+  Notes on how to update libm based on Intel's libm releases
+  ----------------------------------------------------------
+
+This source code in this directory is currently based on Intel libm
+v2.1 as available from:
+
+  http://www.intel.com/software/products/opensource/libraries/num.htm
+
+To ease importing, fix some bugs, and simplify integration into libc,
+it is also necessary to apply the patch at:
+
+  ftp://ftp.hpl.hp.com/pub/linux-ia64/intel-libm-041228.diff.gz
+
+The expectation is that Intel will integrate most if not all of these
+changes into future releases of libm, so this patching step can
+hopefully be omitted in the future.
+
+Once the patched libm sources are extracted in a directory $LIBM, they
+can be imported into the libc source tree at $LIBC with the following
+step:
+
+	$ cd $LIBC/src/sysdep/ia64/fpu
+	$ ./import_intel_libm $LIBM
+
+This should produce a number of "Importing..." messages, without
+showing any errors.
+
+At this point, you should be able to build glibc in the usual fashion.
+We assume you do this in directory $OBJ.  Once the build has
+completed, run "make check" to verify that all (math) checks succeed.
+If these checks succeed, you should also run the following commands to
+verify that the new libm doesn't pollute the name-space and has proper
+size-info for the data objects:
+
+	$ cd $LIBC/src/sysdep/ia64/fpu
+	$ import_check $OBJ/math/
+
+There should be no (unexpected) errors reported by this script.
+
+As an optional step, you may also want to confirm that the new libm
+exports the exact same global symbols as the old one.
+
+If you want to see the changes introduced by the "import_intel_libm"
+script, you can run the commands:
+
+	$ cd $LIBC/src/sysdep/ia64/fpu
+	$ import_diffs
+
+That's it.

+
+// Description
+//=========================================
+// The acos function computes the principal value of the arc cosine of x.
+// acos(0) returns Pi/2, acos(1) returns 0, acos(-1) returns Pi.
+// A doman error occurs for arguments not in the range [-1,+1].
+//
+// The acos function returns the arc cosine in the range [0, Pi] radians.
+//
+// There are 8 paths:
+// 1. x = +/-0.0
+//    Return acos(x) = Pi/2 + x
+//
+// 2. 0.0 < |x| < 0.625
+//    Return acos(x) = Pi/2 - x - x^3 *PolA(x^2)
+//    where PolA(x^2) = A3 + A5*x^2 + A7*x^4 +...+ A35*x^32
+//
+// 3. 0.625 <=|x| < 1.0
+//    Return acos(x) = Pi/2 - asin(x) =
+//                   = Pi/2 - sign(x) * ( Pi/2 - sqrt(R) * PolB(R))
+//    Where R = 1 - |x|,
+//          PolB(R) = B0 + B1*R + B2*R^2 +...+B12*R^12
+//
+//    sqrt(R) is approximated using the following sequence:
+//        y0 = (1 + eps)/sqrt(R) - initial approximation by frsqrta,
+//             |eps| < 2^(-8)
+//        Then 3 iterations are used to refine the result:
+//        H0 = 0.5*y0
+//        S0 = R*y0
+//
+//        d0 = 0.5 - H0*S0
+//        H1 = H0 + d0*H0
+//        S1 = S0 + d0*S0
+//
+//        d1 = 0.5 - H1*S1
+//        H2 = H1 + d0*H1
+//        S2 = S1 + d0*S1
+//
+//        d2 = 0.5 - H2*S2
+//        S3 = S3 + d2*S3
+//
+//        S3 approximates sqrt(R) with enough accuracy for this algorithm
+//
+//    So, the result should be reconstracted as follows:
+//    acos(x) = Pi/2 - sign(x) * (Pi/2 - S3*PolB(R))
+//
+//    But for optimization purposes the reconstruction step is slightly
+//    changed:
+//    acos(x) = Cpi + sign(x)*PolB(R)*S2 - sign(x)*d2*S2*PolB(R)
+//        where Cpi = 0 if x > 0 and Cpi = Pi if x < 0
+//
+// 4. |x| = 1.0
+//    Return acos(1.0) = 0.0, acos(-1.0) = Pi
+//
+// 5. 1.0 < |x| <= +INF
+//    A doman error occurs for arguments not in the range [-1,+1]
+//
+// 6. x = [S,Q]NaN
+//    Return acos(x) = QNaN
+//
+// 7. x is denormal
+//    Return acos(x) = Pi/2 - x,
+//
+// 8. x is unnormal
+//    Normalize input in f8 and return to the very beginning of the function

+// History
+//==============================================================
+// 02/02/00 Initial version
+// 06/28/00 Improved speed
+// 06/31/00 Changed register allocation because of some duplicate macros
+//          moved nan exit bundle up to gain a cycle.
+// 08/15/00 Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 08/17/00 Changed predicate register macro-usage to direct predicate
+//          names due to an assembler bug.
+// 10/17/00 Improved speed of x=0 and x=1 paths, set D flag if x denormal.
+// 03/13/01 Corrected sign of imm1 value in dep instruction.
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 02/06/03 Reordered header: .section, .global, .proc, .align
+// 04/17/03 Moved mutex after label

+// Description
+//=========================================
+// The acosf function computes the principle value of the arc sine of x.
+// A doman error occurs for arguments not in the range [-1,+1].
+
+// The acosf function returns the arc cosine in the range [0, +pi] radians.
+// acos(1) returns +0
+// acos(x) returns a Nan and raises the invalid exception for |x| >1
+
+// |x| <= sqrt(2)/2. get Ax and Bx

+// Overview of operation
+// ==============================================================
+//
+// There are 7 paths:
+// 1. x = 1.0
+//    Return acosh(x) = 0.0
+// 2. 1.0 < x < 1.000499725341796875(0x3FF0020C00000000)
+//    Return acosh(x) = sqrt(x-1) * Pol4(x), where Pol4(x) =
+//      (((x*C4 + C3)*(x-1) + C2)*(x-1) + C1)*(x-1) + C0
+
+// 3. 1.000499725341796875(0x3FF0020C00000000) <= x < 2^63
+//    Return acosh(x) = log(x + sqrt(x^2 -1.0))
+//    To compute x + sqrt(x^2 -1.0) modified Newton Raphson method is used
+//      (3 iterations)
+//    Algorithm description for log function see below.
+//
+// 4. 2^63 <= x < +INF
+//    Return acosh(x) = log(2*x)
+//    Algorithm description for log function see below.
+//
+// 5. x = +INF
+//    Return acosh(x) = +INF
+//
+// 6. x = [S,Q]NaN
+//    Return acosh(x) = QNaN
+//
+// 7. x < 1.0
+//    It's domain error. Error handler with tag = 136 is called
+//
+//==============================================================
+// Algorithm Description for log(x) function
+// Below we are using the fact that inequality x - 1.0 > 2^(-6) is always
+//   true for this acosh implementation
+//
+// Consider  x = 2^N 1.f1 f2 f3 f4...f63
+// Log(x) = log(frcpa(x) x/frcpa(x))
+//        = log(1/frcpa(x)) + log(frcpa(x) x)
+//        = -log(frcpa(x)) + log(frcpa(x) x)
+//
+// frcpa(x)       = 2^-N frcpa((1.f1 f2 ... f63)
+//
+// -log(frcpa(x)) = -log(C)
+//                = -log(2^-N) - log(frcpa(1.f1 f2 ... f63))
+//
+// -log(frcpa(x)) = -log(C)
+//                = +Nlog2 - log(frcpa(1.f1 f2 ... f63))
+//
+// -log(frcpa(x)) = -log(C)
+//                = +Nlog2 + log(frcpa(1.f1 f2 ... f63))
+//
+// Log(x) = log(1/frcpa(x)) + log(frcpa(x) x)
+//
+// Log(x) =  +Nlog2 + log(1./frcpa(1.f1 f2 ... f63)) + log(frcpa(x) x)
+// Log(x) =  +Nlog2 - log(/frcpa(1.f1 f2 ... f63))   + log(frcpa(x) x)
+// Log(x) =  +Nlog2 + T                              + log(frcpa(x) x)
+//
+// Log(x) =  +Nlog2 + T                     + log(C x)
+//
+// Cx = 1 + r
+//
+// Log(x) =  +Nlog2 + T  + log(1+r)
+// Log(x) =  +Nlog2 + T  + Series( r - r^2/2 + r^3/3 - r^4/4 ....)
+//
+// 1.f1 f2 ... f8 has 256 entries.
+// They are 1 + k/2^8, k = 0 ... 255
+// These 256 values are the table entries.
+//
+// Implementation
+//==============================================================
+// C = frcpa(x)
+// r = C * x - 1
+//
+// Form rseries = r + P1*r^2 + P2*r^3 + P3*r^4 + P4*r^5 + P5*r^6
+//
+// x = f * 2*n where f is 1.f_1f_2f_3....f_63
+// Nfloat = float(n)  where n is the true unbiased exponent
+// pre-index = f_1f_2....f_8
+// index = pre_index * 16
+// get the dxt table entry at index + offset = T
+//
+// result = (T + Nfloat * log(2)) + rseries
+//
+// The T table is calculated as follows
+// Form x_k = 1 + k/2^8 where k goes from 0... 255
+//      y_k = frcpa(x_k)
+//      log(1/y_k)  in quad and round to double-extended
+//
+

+// f9 -> f15,  f32 -> f65
+
+// General registers used:
+// r14 -> r27, r32 -> r39

+// There are 7 paths:
+// 1. x = 1.0
+//    Return acoshf(x) = 0.0
+// 2. 1.0 < x < 1.000499725341796875(0x3FF0020C00000000)
+//    Return acoshf(x) = sqrt(x-1) * Pol4(x),

+// 3. 1.000499725341796875(0x3FF0020C00000000) <= x < 2^51
+//    Return acoshf(x) = log(x + sqrt(x^2 -1.0))
+//    To compute x + sqrt(x^2 -1.0) modified Newton Raphson method is used
+//      (2 iterations)
+//    Algorithm description for log function see below.
+//
+// 4. 2^51 <= x < +INF
+//    Return acoshf(x) = log(2*x)
+//    Algorithm description for log function see below.

+// 6. x = [S,Q]NaN
+//    Return acoshf(x) = QNaN
+//
+// 7. x < 1.0
+//    It's domain error. Error handler with tag = 137 is called

+// Algorithm Description for log(x) function
+// Below we are using the fact that inequality x - 1.0 > 2^(-6) is always
+//   true for this acosh implementation
+//
+// Consider  x = 2^N 1.f1 f2 f3 f4...f63
+// Log(x) = log(frcpa(x) x/frcpa(x))
+//        = log(1/frcpa(x)) + log(frcpa(x) x)
+//        = -log(frcpa(x)) + log(frcpa(x) x)
+//
+// frcpa(x)       = 2^-N frcpa((1.f1 f2 ... f63)
+//
+// -log(frcpa(x)) = -log(C)
+//                = -log(2^-N) - log(frcpa(1.f1 f2 ... f63))
+//
+// -log(frcpa(x)) = -log(C)
+//                = +Nlog2 - log(frcpa(1.f1 f2 ... f63))
+//
+// -log(frcpa(x)) = -log(C)
+//                = +Nlog2 + log(frcpa(1.f1 f2 ... f63))
+//
+// Log(x) = log(1/frcpa(x)) + log(frcpa(x) x)
+//
+// Log(x) =  +Nlog2 + log(1./frcpa(1.f1 f2 ... f63)) + log(frcpa(x) x)
+// Log(x) =  +Nlog2 - log(/frcpa(1.f1 f2 ... f63))   + log(frcpa(x) x)
+// Log(x) =  +Nlog2 + T                              + log(frcpa(x) x)
+//
+// Log(x) =  +Nlog2 + T                     + log(C x)
+//
+// Cx = 1 + r
+//
+// Log(x) =  +Nlog2 + T  + log(1+r)
+// Log(x) =  +Nlog2 + T  + Series( r - r^2/2 + r^3/3 - r^4/4 ....)
+//
+// 1.f1 f2 ... f8 has 256 entries.
+// They are 1 + k/2^8, k = 0 ... 255
+// These 256 values are the table entries.
+//
+// Implementation
+//==============================================================
+// C = frcpa(x)
+// r = C * x - 1
+//
+// Form rseries = r + P1*r^2 + P2*r^3 + P3*r^4
+//
+// x = f * 2*n where f is 1.f_1f_2f_3....f_63
+// Nfloat = float(n)  where n is the true unbiased exponent
+// pre-index = f_1f_2....f_8
+// index = pre_index * 8
+// get the dxt table entry at index + offset = T
+//
+// result = (T + Nfloat * log(2)) + rseries
+//
+// The T table is calculated as follows
+// Form x_k = 1 + k/2^8 where k goes from 0... 255
+//      y_k = frcpa(x_k)
+//      log(1/y_k)  in quad and round to double

+//
+// There are 6 paths:
+// 1. x = 1
+//    Return acoshl(x) = 0;
+//
+// 2. x < 1
+//    Return acoshl(x) = Nan (Domain error, error handler call with tag 135);
+//
+// 3. x = [S,Q]Nan or +INF
+//    Return acoshl(x) = x + x;
+//
+// 4. 'Near 1': 1 < x < 1+1/8
+//    Return acoshl(x) = sqrtl(2*y)*(1-P(y)/Q(y)),
+//                   where y = 1, P(y)/Q(y) - rational approximation
+//
+// 5. 'Huges': x > 0.5*2^64
+//    Return acoshl(x) = (logl(2*x-1));
+//
+// 6. 'Main path': 1+1/8 < x < 0.5*2^64

+// The formula is acoshl(x) = sqrtl(2*y)*(1-P(y)/Q(y)),

+//

+// 2) Compute in parallel sqrtl(2*y) and P(y)/Q(y)
+//    a) sqrtl computation method described below (main path algorithm, item 2))
+//       As result we obtain (gg+gl) - multiprecision result
+//       as pair of double extended values
+//    b) P(y) and Q(y) calculated without any extra precision manipulations
+//    c) P/Q division:
+//       y = frcpa(Q)         initial approximation of 1/Q
+//       z = P*y              initial approximation of P/Q

+//
+//       e3 = e + e1^2
+//       y2 = y + y1*e3 = y + y*(e+e^2+..+e^6)

+// **********************************************************************
+//
+// There are 3 parts of x+sqrt(x^2-1) computation:
+//
+//  1) m2 = (m2_hi+m2_lo) = x^2-1 obtaining
+//     ------------------------------------
+//     m2_hi = x2_hi - 1, where x2_hi = x * x;
+//     m2_lo = x2_lo + p1_lo, where
+//                            x2_lo = FMS(x*x-x2_hi),
+//                            p1_lo = (1 + m2_hi) - x2_hi;
+//
+//  2) g = (g_hi+g_lo) = sqrt(m2) = sqrt(m2_hi+m2_lo)
+//     ----------------------------------------------
+//     r = invsqrt(m2_hi) (8-bit reciprocal square root approximation);
+//     g = m2_hi * r (first 8 bit-approximation of sqrt);
+//
+//     h = 0.5 * r;
+//     e = 0.5 - g * h;
+//     g = g * e + g (second 16 bit-approximation of sqrt);
+//
+//     h = h * e + h;
+//     e = 0.5 - g * h;
+//     g = g * e + g (third 32 bit-approximation of sqrt);
+//
+//     h = h * e + h;
+//     e = 0.5 - g * h;
+//     g_hi = g * e + g (fourth 64 bit-approximation of sqrt);
+//
+//     Remainder computation:
+//     h = h * e + h;
+//     d = (m2_hi - g_hi * g_hi) + m2_lo;
+//     g_lo = d * h;
+//
+//  3) b = (b_hi + b_lo) = x + g, where g = (g_hi + g_lo) = sqrt(x^2-1)
+//     -------------------------------------------------------------------
+//     b_hi = (g_hi + x) + gl;
+//     b_lo = (x - b_hi) + g_hi + gl;
+//
+//  Now we pass b presented as sum b_hi + b_lo to special version
+//  of logl function which accept a pair of arguments as
+//  mutiprecision value.
+//
+//  Special log algorithm overview
+//  ================================
+//   Here we use a table lookup method. The basic idea is that in
+//   order to compute logl(Arg) for an argument Arg in [1,2),
+//   we construct a value G such that G*Arg is close to 1 and that
+//   logl(1/G) is obtainable easily from a table of values calculated
+//   beforehand. Thus
+//
+//      logl(Arg) = logl(1/G) + logl((G*Arg - 1))
+//
+//   Because |G*Arg - 1| is small, the second term on the right hand
+//   side can be approximated by a short polynomial. We elaborate
+//   this method in four steps.
+//
+//   Step 0: Initialization
+//
+//   We need to calculate logl( X+1 ). Obtain N, S_hi such that
+//
+//      X = 2^N * ( S_hi + S_lo )   exactly
+//
+//   where S_hi in [1,2) and S_lo is a correction to S_hi in the sense
+//   that |S_lo| <= ulp(S_hi).
+//
+//   For the special version of logl: S_lo = b_lo
+//   !-----------------------------------------------!
+//
+//   Step 1: Argument Reduction
+//
+//   Based on S_hi, obtain G_1, G_2, G_3 from a table and calculate
+//
+//      G := G_1 * G_2 * G_3
+//      r := (G * S_hi - 1) + G * S_lo
+//
+//   These G_j's have the property that the product is exactly
+//   representable and that |r| < 2^(-12) as a result.
+//
+//   Step 2: Approximation
+//
+//   logl(1 + r) is approximated by a short polynomial poly(r).
+//
+//   Step 3: Reconstruction
+//
+//   Finally, logl( X ) = logl( X+1 ) is given by
+//
+//   logl( X )   =   logl( 2^N * (S_hi + S_lo) )
+//                 ~=~  N*logl(2) + logl(1/G) + logl(1 + r)
+//                 ~=~  N*logl(2) + logl(1/G) + poly(r).
+//
+//   For detailed description see logl or log1pl function, regular path.

+// Implementation
+//
+// For |s| in [2^{-4}, sqrt(2)/2]:
+// Let t= 2^k*1.b1 b2..b6 1, where s= 2^k*1.b1 b2.. b52
+// acos(s)= pi/2-asin(t)-asin(r), where r= s*sqrt(1-t^2)-t*sqrt(1-s^2), i.e.
+// r= (s-t)*sqrt(1-t^2)-t*sqrt(1-t^2)*(sqrt((1-s^2)/(1-t^2))-1)
+// asin(r)-r evaluated as 9-degree polynomial (c3*r^3+c5*r^5+c7*r^7+c9*r^9)
+// The 64-bit significands of sqrt(1-t^2), 1/(1-t^2) are read from the table,
+// along with the high and low parts of asin(t) (stored as two double precision
+// values)
+//
+// |s| in (sqrt(2)/2, sqrt(255/256)):
+// Let t= 2^k*1.b1 b2..b6 1, where (1-s^2)*frsqrta(1-s^2)= 2^k*1.b1 b2..b6..
+// acos(|s|)= asin(t)-asin(r)
+// acos(-|s|)=pi-asin(t)+asin(r),   r= s*t-sqrt(1-s^2)*sqrt(1-t^2)
+// To minimize accumulated errors, r is computed as
+// r= (t*s)_s-t^2*y*z+z*y*(t^2-1+s^2)_s+z*y*(1-s^2)_s*x+z'*y*(1-s^2)*PS29+
+// +(t*s-(t*s)_s)+z*y*((t^2-1-(t^2-1+s^2)_s)+s^2)+z*y*(1-s^2-(1-s^2)_s)+
+// +ez*z'*y*(1-s^2)*(1-x),
+// where y= frsqrta(1-s^2), z= (sqrt(1-t^2))_s (rounded to 24 significant bits)
+// z'= sqrt(1-t^2), x= ((1-s^2)*y^2-1)/2
+//
+// |s|<2^{-4}: evaluate asin(s) as 17-degree polynomial, return pi/2-asin(s)
+// (or simply return pi/2-s, if|s|<2^{-64})
+//
+// |s| in [sqrt(255/256), 1): acos(|s|)= asin(sqrt(1-s^2))
+// acos(-|s|)= pi-asin(sqrt(1-s^2))
+// use 17-degree polynomial for asin(sqrt(1-s^2)),
+// 9-degree polynomial to evaluate sqrt(1-s^2)
+// High order term is (pi)_high-(y*(1-s^2))_high, for s<0,
+// or y*(1-s^2)_s, for s>0

+
+// Description
+//=========================================
+// The asin function computes the principal value of the arc sine of x.
+// asin(0) returns 0, asin(1) returns pi/2, asin(-1) returns -pi/2.
+// A doman error occurs for arguments not in the range [-1,+1].
+//
+// The asin function returns the arc sine in the range [-pi/2, +pi/2] radians.
+//
+// There are 8 paths:
+// 1. x = +/-0.0
+//    Return asin(x) = +/-0.0
+//
+// 2. 0.0 < |x| < 0.625
+//    Return asin(x) = x + x^3 *PolA(x^2)
+//    where PolA(x^2) = A3 + A5*x^2 + A7*x^4 +...+ A35*x^32
+//
+// 3. 0.625 <=|x| < 1.0
+//    Return asin(x) = sign(x) * ( Pi/2 - sqrt(R) * PolB(R))
+//    Where R = 1 - |x|,
+//          PolB(R) = B0 + B1*R + B2*R^2 +...+B12*R^12
+//
+//    sqrt(R) is approximated using the following sequence:
+//        y0 = (1 + eps)/sqrt(R) - initial approximation by frsqrta,
+//             |eps| < 2^(-8)
+//        Then 3 iterations are used to refine the result:
+//        H0 = 0.5*y0
+//        S0 = R*y0
+//
+//        d0 = 0.5 - H0*S0
+//        H1 = H0 + d0*H0
+//        S1 = S0 + d0*S0
+//
+//        d1 = 0.5 - H1*S1
+//        H2 = H1 + d0*H1
+//        S2 = S1 + d0*S1
+//
+//        d2 = 0.5 - H2*S2
+//        S3 = S3 + d2*S3
+//
+//        S3 approximates sqrt(R) with enough accuracy for this algorithm
+//
+//    So, the result should be reconstracted as follows:
+//    asin(x) = sign(x) * (Pi/2 - S3*PolB(R))
+//
+//    But for optimization perposes the reconstruction step is slightly
+//    changed:
+//    asin(x) = sign(x)*(Pi/2 - PolB(R)*S2) + sign(x)*d2*S2*PolB(R)
+//
+// 4. |x| = 1.0
+//    Return asin(x) = sign(x)*Pi/2
+//
+// 5. 1.0 < |x| <= +INF
+//    A doman error occurs for arguments not in the range [-1,+1]
+//
+// 6. x = [S,Q]NaN
+//    Return asin(x) = QNaN
+//
+// 7. x is denormal
+//    Return asin(x) = x + x^3,
+//
+// 8. x is unnormal
+//    Normalize input in f8 and return to the very beginning of the function
+//

+// History
+//==============================================================
+// 02/02/00 Initial version
+// 06/28/00 Improved speed
+// 06/31/00 Changed register allocation because of some duplicate macros
+//          moved nan exit bundle up to gain a cycle.
+// 08/08/00 Improved speed by avoiding SIR flush.
+// 08/15/00 Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 08/17/00 Changed predicate register macro-usage to direct predicate
+//          names due to an assembler bug.
+// 10/17/00 Improved speed of x=0 and x=1 paths, set D flag if x denormal.
+// 03/13/01 Corrected sign of imm1 value in dep instruction.
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 02/06/03 Reordered header: .section, .global, .proc, .align

+// Background
+//
+// Implementation
+//
+// For |s| in [2^{-4}, sqrt(2)/2]:
+// Let t= 2^k*1.b1 b2..b6 1, where s= 2^k*1.b1 b2.. b52
+// asin(s)= asin(t)+asin(r), where r= s*sqrt(1-t^2)-t*sqrt(1-s^2), i.e.
+// r= (s-t)*sqrt(1-t^2)-t*sqrt(1-t^2)*(sqrt((1-s^2)/(1-t^2))-1)
+// asin(r)-r evaluated as 9-degree polynomial (c3*r^3+c5*r^5+c7*r^7+c9*r^9)
+// The 64-bit significands of sqrt(1-t^2), 1/(1-t^2) are read from the table,
+// along with the high and low parts of asin(t) (stored as two double precision
+// values)
+//
+// |s| in (sqrt(2)/2, sqrt(255/256)):
+// Let t= 2^k*1.b1 b2..b6 1, where (1-s^2)*frsqrta(1-s^2)= 2^k*1.b1 b2..b6..
+// asin(|s|)= pi/2-asin(t)+asin(r), r= s*t-sqrt(1-s^2)*sqrt(1-t^2)
+// To minimize accumulated errors, r is computed as
+// r= (t*s)_s-t^2*y*z+z*y*(t^2-1+s^2)_s+z*y*(1-s^2)_s*x+z'*y*(1-s^2)*PS29+
+// +(t*s-(t*s)_s)+z*y*((t^2-1-(t^2-1+s^2)_s)+s^2)+z*y*(1-s^2-(1-s^2)_s)+
+// +ez*z'*y*(1-s^2)*(1-x),
+// where y= frsqrta(1-s^2), z= (sqrt(1-t^2))_s (rounded to 24 significant bits)
+// z'= sqrt(1-t^2), x= ((1-s^2)*y^2-1)/2
+//
+// |s|<2^{-4}: evaluate as 17-degree polynomial
+// (or simply return s, if|s|<2^{-64})
+//
+// |s| in [sqrt(255/256), 1): asin(|s|)= pi/2-asin(sqrt(1-s^2))
+// use 17-degree polynomial for asin(sqrt(1-s^2)),
+// 9-degree polynomial to evaluate sqrt(1-s^2)
+// High order term is (pi/2)_high-(y*(1-s^2))_high

+// History
+//==============================================================
+// 02/02/00  Initial version
+// 04/04/00  Unwind support added
+// 08/15/00  Bundle added after call to __libm_error_support to properly
+//           set [the previously overwritten] GR_Parameter_RESULT.
+// 08/17/00  Changed predicate register macro-usage to direct predicate
+//           names due to an assembler bug.
+// 09/28/00  Updated to set invalid on SNaN inputs
+// 01/19/01  Fixed flags for small results
+// 04/13/01  Rescheduled to make all paths faster
+// 05/20/02  Cleaned up namespace and sf0 syntax
+// 08/20/02  Corrected inexact flag and directed rounding symmetry bugs
+// 02/06/03  Reordered header: .section, .global, .proc, .align
+// 04/17/03  Added missing mutex directive
+// 12/23/03  atan2(NaN1,NaN2) now QNaN1, for consistency with atan2f, atan2l
+//
+// API
+//==============================================================
+// double atan2(double Y, double X)
+//
+// Overview of operation
+//==============================================================
+//
+// The atan2 function returns values in the interval [-pi,+pi].
+//
+// There are two basic paths: swap true and swap false.
+// atan2(Y,X) ==> atan2(V/U) where U >= V. If Y > X, we must swap.
+//
+// p6  swap True    |Y| > |X|
+// p7  swap False   |Y| <= |X|
+// p8  X+   (If swap=True p8=p9=0)
+// p9  X-
+//
+// all the other predicates p10 thru p15 are false for the main path
+//
+// Simple trigonometric identities show
+//   Region 1 (-45 to +45 degrees):
+//         X>0, |Y|<=X, V=Y, U=X     atan2(Y,X) = sgnY * (0 + atan(V/U))
+//
+//   Region 2 (-90 to -45 degrees, and +45 to +90 degrees):
+//         X>0, |Y|>X, V=X, U=Y      atan2(Y,X) = sgnY * (pi/2 - atan(V/U))
+//
+//   Region 3 (-135 to -90 degrees, and +90 to +135 degrees):
+//         X<0, |Y|>X, V=X, U=Y      atan2(Y,X) = sgnY * (pi/2 + atan(V/U))
+//
+//   Region 4 (-180 to -135 degrees, and +135 to +180 degrees):
+//         X<0, |Y|<=X, V=Y, U=X      atan2(Y,X) = sgnY * (pi - atan(V/U))
+//
+// So the result is always of the form atan2(Y,X) = P + sgnXY * atan(V/U)
+//
+// We compute atan(V/U) from the identity
+//      atan(z) + atan([(V/U)-z] / [1+(V/U)z])
+//      where z is a limited precision approximation (16 bits) to V/U
+//
+// z is calculated with the assistance of the frcpa instruction.
+//
+// atan(z) is calculated by a polynomial z + z^3 * p(w),  w=z^2
+// where p(w) = P0+P1*w+...+P22*w^22
+//
+// Let d = [(V/U)-z] / [1+(V/U)z]) = (V-U*z)/(U+V*z)
+//
+// Approximate atan(d) by d + P0*d^3
+// Let F = 1/(U+V*z) * (1-a), where |a|< 2^-8.8.
+// Compute q(a) = 1 + a + ... + a^5.
+// Then F*q(a) approximates the reciprocal to more than 50 bits.

+// Description
+//=========================================
+// The atan2 function computes the principle value of the arc tangent of y/x using
+// the signs of both arguments to determine the quadrant of the return value.
+// A domain error may occur if both arguments are zero.
+
+// The atan2 function returns the arc tangent of y/x in the range [-pi,+pi] radians.
+
+//..
+//..Let (v,u) = (y,x) if |y| <= |x|, and (v,u) = (x,y) otherwise. Note that
+//..v and u can be negative. We state the relationship between atan2(y,x) and
+//..atan(v/u).
+//..
+//..Let swap = false if v = y, and swap = true if v = x.
+//..Define C according to the matrix
+//..
+//..                   TABLE FOR C
+//..                              x +ve       x -ve
+//..   no swap (swap = false)    sgn(y)*0     sgn(y)*pi
+//..   swap    (swap = true )    sgn(y)*pi/2  sgn(y)*pi/2
+//..
+//..   atan2(y,x) =  C +  atan(v/u)  if no swap
+//..   atan2(y,x) =  C -  atan(v/u)  if  swap
+//..
+//..These relationship is more efficient to compute as we accommodate signs in v and u
+//..saving the need to obtain the absolute value before computation can proceed.
+//..
+//..Suppose (v,u) = (y,x), we calculate atan(v/u) as follows:
+//..A = y * frcpa(x)    (so A = (y/x)(1 - beta))
+//..atan(y/x) = atan(A) + atan( ((y/x)-A))/(1 + (y/x)A) ), the second term is
+//..a correction.
+//..atan(A) is approximated by a polynomial
+//..A + p1 A^3 + p2 A^5 + ... + p10 A^21,
+//..atan(G) is approximated as follows:
+//..Let G = (y - Ax)/(x + Ay), atan(G) can be approximated by G + g * p1
+//..where g is a limited precision approximation to G via g = (y - Ax)*frcpa(x + Ay).
+//..
+//..Suppose (v,u) = (x,y), we calculate atan(v/u) as follows:
+//..Z = x * frcpa(y)    (so Z = (x/y)(1 - beta))
+//..atan(x/y) = atan(Z) + atan( ((x/y)-Z))/(1 + (x/y)Z) ), the second term is
+//..a correction.
+//..atan(Z) is approximated by a polynomial
+//..Z + p1 Z^3 + p2 Z^5 + ... + p10 Z^21,
+//..atan(T) is approximated as follows:
+//..Let T = (x - Ay)/(y + Ax), atan(T) can be approximated by T + t * p1
+//..where t is a limited precision approximation to T via t = (x - Ay)*frcpa(y + Ax).
+//..
+//..
+//..A = y * frcpa(x)
+//..atan(A) ~=~ A + p1 A^3 + ... + P10 A^21
+//..
+//..This polynomial is computed as follows:
+//..Asq = A*A; Acub = A*Asq, A4 = Asq*Asq
+//..A5 = Asq*Acub, A6 = Asq*A4; A11 = A5 * A6
+//..
+//..poly_A1 = p9 + Asq*p10, poly_A2 = p7 + Asq*p8, poly_A3 = p5 + Asq*p6
+//..poly_A1 = poly_A2 + A4 * poly_A1
+//..poly_A1 = poly_A3 + A4 * poly_A1
+//..
+//..poly_A4 = p1 * A
+//,,poly_A5 = p3 + Asq * p4, poly_A4 = A + Asq*poly_A4
+//..poly_A5 = p2 + Asq * poly_A5
+//..poly_A4 = poly_A4 + A5 * poly_A5
+//..
+//..atan_A = poly_A4 + A11 * poly_A1
+//..
+//..atan(G) is approximated as follows:
+//..G_numer = y - A*x, G_denom = x + A*y
+//..H1 = frcpa(G_denom)
+//..H_beta = 1 - H1 * G_denom
+//..H2 = H1 + H1 * H_beta
+//..H_beta2 = H_beta*H_beta
+//..H3 = H2 + H2*H_beta2
+//..g = H1 * G_numer; gsq = g*g; atan_G = g*p1, atan_G = atan_G*gsq
+//..atan_G = G_numer*H3 + atan_G
+//..
+//..
+//..A = y * frcpa(x)
+//..atan(A) ~=~ A + p1 A^3 + ... + P10 A^21
+//..
+//..This polynomial is computed as follows:
+//..Asq = A*A; Acub = A*Asq, A4 = Asq*Asq

+// double atanh(double)
+//
+// Overview of operation
+// ==============================================================
+//
+// There are 7 paths:
+// 1. x = +/-0.0
+//    Return atanh(x) = +/-0.0
+//
+// 2. 0.0 < |x| < 1/4
+//    Return atanh(x) = Po2l(x),
+//    where Po2l(x) = (((((((((C9*x^2 + C8)*x^2 + C7)*x^2 + C6)*x^2 +
+//          C5)*x^2 + C4)*x^2 + C3)*x^2 + C2)*x^2 + C1)* x^2 + C0)*x^3 + x
+// 3. 1/4 <= |x| < 1
+//    Return atanh(x) = sign(x) * log((1 + |x|)/(1 - |x|))
+//    To compute (1 + |x|)/(1 - |x|) modified Newton Raphson method is used
+//    (3 iterations)
+//    Algorithm description for log function see below.
+//
+// 4. |x| = 1
+//    Return atanh(x) = sign(x) * +INF
+//
+// 5. 1 < |x| <= +INF
+//    Return atanh(x) = QNaN
+//
+// 6. x = [S,Q]NaN
+//    Return atanh(x) = QNaN
+//
+// 7. x = denormal
+//    Return atanh(x) = x
+//
+//==============================================================
+// Algorithm Description for log(x) function
+// Below we are using the fact that inequality x - 1.0 > 2^(-6) is always true
+// for this atanh implementation
+//
+// Consider  x = 2^N 1.f1 f2 f3 f4...f63
+// Log(x) = log(x * frcpa(x) / frcpa(x))
+//        = log(x * frcpa(x)) + log(1/frcpa(x))
+//        = log(x * frcpa(x)) - log(frcpa(x))
+//
+// frcpa(x)       = 2^-N * frcpa(1.f1 f2 ... f63)
+//
+// -log(frcpa(x)) = -log(C)
+//                = -log(2^-N) - log(frcpa(1.f1 f2 ... f63))
+//
+// -log(frcpa(x)) = -log(C)
+//                = N*log2 - log(frcpa(1.f1 f2 ... f63))
+//
+//
+// Log(x) = log(1/frcpa(x)) + log(frcpa(x) x)
+//
+// Log(x) = N*log2 + log(1./frcpa(1.f1 f2 ... f63)) + log(x * frcpa(x))
+// Log(x) = N*log2 + T                              + log(frcpa(x) x)
+//
+// Log(x) = N*log2 + T                              + log(C * x)
+//
+// C * x = 1 + r
+//
+// Log(x) = N*log2 + T + log(1 + r)
+// Log(x) = N*log2 + T + Series(r - r^2/2 + r^3/3 - r^4/4 + ...)
+//
+// 1.f1 f2 ... f8 has 256 entries.
+// They are 1 + k/2^8, k = 0 ... 255
+// These 256 values are the table entries.
+//
+// Implementation
+//==============================================================
+// C = frcpa(x)
+// r = C * x - 1
+//
+// Form rseries = r + P1*r^2 + P2*r^3 + P3*r^4 + P4*r^5 + P5*r^6
+//
+// x = f * 2*N where f is 1.f_1f_2f_3...f_63
+// Nfloat = float(n)  where n is the true unbiased exponent
+// pre-index = f_1f_2....f_8
+// index = pre_index * 16
+// get the dxt table entry at index + offset = T
+//
+// result = (T + Nfloat * log(2)) + rseries
+//
+// The T table is calculated as follows
+// Form x_k = 1 + k/2^8 where k goes from 0... 255
+//      y_k = frcpa(x_k)
+//      log(1/y_k)  in quad and round to double-extended
+//
+//
+// Registers used
+//==============================================================
+// Floating Point registers used:
+// f8, input
+// f32 -> f77
+
+// General registers used:
+// r14 -> r27, r33 -> r39
+
+// Predicate registers used:
+// p6 -> p14
+
+// p10, p11      to indicate is argument positive or negative
+// p12           to filter out case when x = [Q,S]NaN or +/-0
+// p13           to filter out case when x = denormal
+// p6, p7        to filter out case when |x| >= 1
+// p8            to filter out case when |x| < 1/4

+//
+// Overview of operation
+//==============================================================
+// Background
+//
+//
+// There are 7 paths:
+// 1. x = +/-0.0
+//    Return atanhf(x) = +/-0.0
+//
+// 2. 0.0 < |x| <= MAX_DENORMAL_ABS
+//    Return atanhf(x) = x + sign(x)*x^2
+//
+// 3. MAX_DENORMAL_ABS < |x| < 2^(-20)
+//    Return atanhf(x) = Pol3(x), where Pol3(x) = x + x^3
+//
+// 4. 2^(-20) <= |x| < 1
+//    Return atanhf(x) = 0.5 * (log(1 + x) - log(1 - x))
+//    Algorithm description for log function see below.
+//
+// 5. |x| = 1
+//    Return atanhf(x) = sign(x) * +INF
+//
+// 6. 1 < |x| <= +INF
+//    Return atanhf(x) = QNaN
+//
+// 7. x = [S,Q]NaN
+//    Return atanhf(x) = QNaN
+//
+//==============================================================
+// Algorithm Description for log(x) function
+//
+// Consider  x = 2^N * 1.f1 f2 f3 f4...f63
+// log(x) = log(x * frcpa(x) / frcpa(x))
+//        = log(x * frcpa(x)) + log(1/frcpa(x))
+//        = log(x * frcpa(x)) - log(frcpa(x))
+//
+// frcpa(x) = 2^(-N) * frcpa(1.f1 f2 ... f63)
+//
+// -log(frcpa(x)) = -log(C)
+//                = -log(2^(-N)) - log(frcpa(1.f1 f2 ... f63))
+//
+// -log(frcpa(x)) = -log(C)
+//                = N*log2 - log(frcpa(1.f1 f2 ... f63))
+//
+//
+// log(x) = log(1/frcpa(x)) + log(frcpa(x) x)
+//
+// log(x) = N*log2 + log(1./frcpa(1.f1 f2 ... f63)) + log(x * frcpa(x))
+// log(x) = N*log2 + T                              + log(frcpa(x) x)
+//
+// Log(x) = N*log2 + T                              + log(C * x)
+//
+// C * x = 1 + r
+//
+// log(x) = N*log2 + T + log(1 + r)
+// log(x) = N*log2 + T + Series(r)
+//
+// 1.f1 f2 ... f8 has 256 entries.
+// They are 1 + k/2^8, k = 0 ... 255
+// These 256 values are the table entries.
+//
+// Implementation
+//==============================================================
+// C = frcpa(x)
+// r = C * x - 1
+//
+// Form rseries = r + P1*r^2 + P2*r^3 + P3*r^4
+//
+// x = f * 2*N where f is 1.f_1f_2f_3...f_63
+// Nfloat = float(n)  where n is the true unbiased exponent
+// pre-index = f_1f_2....f_8
+// index = pre_index * 16
+// get the dxt table entry at index + offset = T
+//
+// result = (T + Nfloat * log(2)) + rseries
+//
+// The T table is calculated as follows
+// Form x_k = 1 + k/2^8 where k goes from 0... 255
+//      y_k = frcpa(x_k)
+//      log(1/y_k)  in quad and round to double-extended
+
+// Registers used
+//==============================================================
+// Floating Point registers used:
+// f8, input
+// f32 -> f59
+
+// General registers used:
+// r14 -> r29, r32 -> r39
+
+// Predicate registers used:
+// p6 -> p9
+
+// p6           to filter out case when |x| >= 1
+// p7           to filter out case when x = [Q,S]NaN or +/-0
+// p8           to filter out case when |x| < 2^(-20)
+// p9           to filter out case when x = denormal

+// Overview
+//
+// The method consists of two cases.
+//
+// If      |x| < 1/32  use case atanhl_near_zero;
+// else                 use case atanhl_regular;
+//
+// Case atanhl_near_zero:
+//
+//   atanhl(x) can be approximated by the Taylor series expansion
+//   up to order 17.
+//
+// Case atanhl_regular:
+//
+//   Here we use formula atanhl(x) = sign(x)*log1pl(2*|x|/(1-|x|))/2 and
+//   calculation is subdivided into two stages. The first stage is
+//   calculating of X = 2*|x|/(1-|x|). The second one is calculating of
+//   sign(x)*log1pl(X)/2. To obtain required accuracy we use precise division
+//   algorythm output of which is a pair of two extended precision values those
+//   approximate result of division with accuracy higher than working
+//   precision. This pair is passed to modified log1pl function.
+//
+//
+//   1. calculating of X = 2*|x|/(1-|x|)
+//   ( based on Peter Markstein's "IA-64 and Elementary Functions" book )
+//   ********************************************************************
+//
+//     a = 2*|x|
+//     b = 1 - |x|
+//     b_lo = |x| - (1 - b)
+//
+//     y = frcpa(b)         initial approximation of 1/b
+//     q = a*y              initial approximation of a/b
+//
+//     e = 1 - b*y
+//     e2 = e + e^2
+//     e1 = e^2
+//     y1 = y + y*e2 = y + y*(e+e^2)
+//
+//     e3 = e + e1^2
+//     y2 = y + y1*e3 = y + y*(e+e^2+..+e^6)
+//
+//     r = a - b*q
+//     e = 1 - b*y2
+//     X = q + r*y2         high part of a/b
+//
+//     y3 = y2 + y2*e4
+//     r1 = a - b*X
+//     r1 = r1 - b_lo*X
+//     X_lo = r1*y3         low part of a/b
+//
+//   2. special log1p algorithm overview
+//   ***********************************
+//
+//    Here we use a table lookup method. The basic idea is that in
+//    order to compute logl(Arg) = log1pl (Arg-1) for an argument Arg in [1,2),
+//    we construct a value G such that G*Arg is close to 1 and that
+//    logl(1/G) is obtainable easily from a table of values calculated
+//    beforehand. Thus
+//
+//      logl(Arg) = logl(1/G) + logl(G*Arg)
+//           = logl(1/G) + logl(1 + (G*Arg - 1))
+//
+//    Because |G*Arg - 1| is small, the second term on the right hand
+//    side can be approximated by a short polynomial. We elaborate
+//    this method in several steps.
+//
+//    Step 0: Initialization
+//    ------
+//    We need to calculate logl(X + X_lo + 1). Obtain N, S_hi such that
+//
+//      X + X_lo + 1 = 2^N * ( S_hi + S_lo )   exactly
+//
+//    where S_hi in [1,2) and S_lo is a correction to S_hi in the sense
+//    that |S_lo| <= ulp(S_hi).
+//
+//    For the special version of log1p we add X_lo to S_lo (S_lo = S_lo + X_lo)
+//    !-----------------------------------------------------------------------!
+//
+//    Step 1: Argument Reduction
+//    ------
+//    Based on S_hi, obtain G_1, G_2, G_3 from a table and calculate
+//
+//      G := G_1 * G_2 * G_3
+//      r := (G * S_hi - 1) + G * S_lo
+//
+//    These G_j's have the property that the product is exactly
+//    representable and that |r| < 2^(-12) as a result.
+//
+//    Step 2: Approximation
+//    ------
+//    logl(1 + r) is approximated by a short polynomial poly(r).
+//
+//    Step 3: Reconstruction
+//    ------
+//    Finally, log1pl(X + X_lo) = logl(X + X_lo + 1) is given by
+//
+//    logl(X + X_lo + 1) =  logl(2^N * (S_hi + S_lo))
+//                      ~=~ N*logl(2) + logl(1/G) + logl(1 + r)
+//                      ~=~ N*logl(2) + logl(1/G) + poly(r).

+// 04/04/00 Unwind support added
+// 08/15/00 Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 05/07/01 Reworked to improve speed of all paths
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 11/15/02 Improved speed with new algorithm
+// 03/31/05 Reformatted delimiters between data tables

+
+// Overview of operation
+//==============================================================
+// Case 1:  0 < |x| < 0.25
+//  Evaluate cosh(x) by a 12th order polynomial
+//  Care is take for the order of multiplication; and A2 is not exactly 1/4!,
+//  A3 is not exactly 1/6!, etc.
+//  cosh(x) = 1 + (A1*x^2 + A2*x^4 + A3*x^6 + A4*x^8 + A5*x^10 + A6*x^12)
+//
+// Case 2:  0.25 < |x| < 710.47586
+//  Algorithm is based on the identity cosh(x) = ( exp(x) + exp(-x) ) / 2.
+//  The algorithm for exp is described as below.  There are a number of
+//  economies from evaluating both exp(x) and exp(-x).  Although we
+//  are evaluating both quantities, only where the quantities diverge do we
+//  duplicate the computations.  The basic algorithm for exp(x) is described
+//  below.
+//
+// Take the input x. w is "how many log2/128 in x?"
+//  w = x * 128/log2
+//  n = int(w)
+//  x = n log2/128 + r + delta
+
+//  n = 128M + index_1 + 2^4 index_2
+//  x = M log2 + (log2/128) index_1 + (log2/8) index_2 + r + delta
+
+//  exp(x) = 2^M  2^(index_1/128)  2^(index_2/8) exp(r) exp(delta)
+//       Construct 2^M
+//       Get 2^(index_1/128) from table_1;
+//       Get 2^(index_2/8)   from table_2;

+//*********************************************************************
+// 02/02/00 Initial version
+// 02/16/00 The error tag for coshf overflow changed to 65 (from 64).
+// 04/04/00 Unwind support added
+// 08/15/00 Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 05/07/01 Reworked to improve speed of all paths
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 11/15/02 Improved algorithm based on expf
+// 03/31/05 Reformatted delimiters between data tables

+// Overview of operation
+//*********************************************************************
+// Case 1:  0 < |x| < 0.25
+//  Evaluate cosh(x) by a 8th order polynomial
+//  Care is take for the order of multiplication; and A2 is not exactly 1/4!,
+//  A3 is not exactly 1/6!, etc.
+//  cosh(x) = 1 + (A1*x^2 + A2*x^4 + A3*x^6 + A4*x^8)
+//
+// Case 2:  0.25 < |x| < 89.41598
+//  Algorithm is based on the identity cosh(x) = ( exp(x) + exp(-x) ) / 2.
+//  The algorithm for exp is described as below.  There are a number of
+//  economies from evaluating both exp(x) and exp(-x).  Although we
+//  are evaluating both quantities, only where the quantities diverge do we
+//  duplicate the computations.  The basic algorithm for exp(x) is described
+//  below.
+//
+// Take the input x. w is "how many log2/128 in x?"
+//  w = x * 64/log2
+//  NJ = int(w)
+//  x = NJ*log2/64 + R
+
+//  NJ = 64*n + j
+//  x = n*log2 + (log2/64)*j + R
+//
+//  So, exp(x) = 2^n * 2^(j/64)* exp(R)
+//
+//  T =  2^n * 2^(j/64)
+//       Construct 2^n
+//       Get 2^(j/64) table
+//           actually all the entries of 2^(j/64) table are stored in DP and
+//           with exponent bits set to 0 -> multiplication on 2^n can be
+//           performed by doing logical "or" operation with bits presenting 2^n
+
+//  exp(R) = 1 + (exp(R) - 1)
+//  P = exp(R) - 1 approximated by Taylor series of 3rd degree
+//      P = A3*R^3 + A2*R^2 + R, A3 = 1/6, A2 = 1/2
+//
+
+//  The final result is reconstructed as follows
+//  exp(x) = T + T*P

+// History
+//==============================================================
+// 02/02/00 Initial version
+// 04/04/00 Unwind support added
+// 08/15/00 Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 01/23/01 Set inexact flag for large args.
+// 05/07/01 Reworked to improve speed of all paths
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 12/06/02 Improved performance
+//
+// API
+//==============================================================
+// long double = coshl(long double)
+// input  floating point f8
+// output floating point f8
+//
+// Registers used
+//==============================================================
+// general registers:
+// r14 -> r40
+// predicate registers used:
+// p6 -> p11
+// floating-point registers used:
+// f9 -> f15; f32 -> f90;
+// f8 has input, then output
+//
+// Overview of operation
+//==============================================================
+// There are seven paths
+// 1. 0 < |x| < 0.25          COSH_BY_POLY
+// 2. 0.25 <=|x| < 32         COSH_BY_TBL
+// 3. 32 <= |x| < 11357.21655 COSH_BY_EXP (merged path with COSH_BY_TBL)
+// 4. |x| >= 11357.21655      COSH_HUGE
+// 5. x=0                     Done with early exit
+// 6. x=inf,nan               Done with early exit
+// 7. x=denormal              COSH_DENORM
+//
+// For double extended we get overflow for x >= 400c b174 ddc0 31ae c0ea

+//
+//
+// 1. COSH_BY_POLY   0 < |x| < 0.25
+// ===============
+// Evaluate cosh(x) by a 12th order polynomial
+// Care is take for the order of multiplication; and P2 is not exactly 1/4!,
+// P3 is not exactly 1/6!, etc.
+// cosh(x) = 1 + (P1*x^2 + P2*x^4 + P3*x^6 + P4*x^8 + P5*x^10 + P6*x^12)
+//
+// 2. COSH_BY_TBL   0.25 <= |x| < 32.0
+// =============
+// cosh(x) = cosh(B+R)
+//         = cosh(B)cosh(R) + sinh(B)sinh(R)
+//
+// ax = |x| = M*log2/64 + R
+// B = M*log2/64
+// M = 64*N + j
+//   We will calculate M and get N as (M-j)/64
+//   The division is a shift.
+// exp(B)  = exp(N*log2 + j*log2/64)
+//         = 2^N * 2^(j*log2/64)
+// cosh(B) = 1/2(e^B + e^-B)
+//         = 1/2(2^N * 2^(j*log2/64) + 2^-N * 2^(-j*log2/64))
+// cosh(B) = (2^(N-1) * 2^(j*log2/64) + 2^(-N-1) * 2^(-j*log2/64))
+// sinh(B) = (2^(N-1) * 2^(j*log2/64) - 2^(-N-1) * 2^(-j*log2/64))
+// 2^(j*log2/64) is stored as Tjhi + Tjlo , j= -32,....,32
+// Tjhi is double-extended (80-bit) and Tjlo is single(32-bit)
+//
+// R = ax - M*log2/64
+// R = ax - M*log2_by_64_hi - M*log2_by_64_lo
+// exp(R) = 1 + R +R^2(1/2! + R(1/3! + R(1/4! + ... + R(1/n!)...)
+//        = 1 + p_odd + p_even
+//        where the p_even uses the A coefficients and the p_even uses
+//        the B coefficients
+//
+// So sinh(R) = 1 + p_odd + p_even -(1 -p_odd -p_even)/2 = p_odd
+//    cosh(R) = 1 + p_even
+//    cosh(B) = C_hi + C_lo
+//    sinh(B) = S_hi
+// cosh(x) = cosh(B)cosh(R) + sinh(B)sinh(R)
+//
+// 3. COSH_BY_EXP   32.0 <= |x| < 11357.21655  ( 400c b174 ddc0 31ae c0ea )
+// ==============

+// History
+//==============================================================
+// 2/02/00  Initial version
+// 3/07/00  exp(inf)  = inf but now does NOT call error support
+//          exp(-inf) = 0   but now does NOT call error support
+// 4/04/00  Unwind support added
+// 8/15/00  Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 11/30/00 Reworked to shorten main path, widen main path to include all
+//          args in normal range, and add quick exit for 0, nan, inf.
+// 12/05/00 Loaded constants earlier with setf to save 2 cycles.
+// 02/05/02 Corrected uninitialize predicate in POSSIBLE_UNDERFLOW path
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 09/07/02 Force inexact flag
+// 11/15/02 Split underflow path into zero/nonzero; eliminated fma in main path
+// 05/30/03 Set inexact flag on unmasked overflow/underflow
+// 03/31/05 Reformatted delimiters between data tables

+// 09/06/02 Improved performance; no inexact flags on exact cases
+// 01/29/03 Added missing } to bundle templates

+//
+// Overview of operation
+//==============================================================
+// Background
+//
+// Implementation
+//
+// Let x= (K + fh + fl + r)/log2(10), where
+// K is an integer, fh= 0.b1 b2 b3 b4 b5,
+// fl= 2^{-5}* 0.b6 b7 b8 b8 b10 (fh, fl >= 0),
+// and |r|<2^{-11}
+// Th is a table that stores 2^fh (32 entries) rounded to
+// double extended precision (only mantissa is stored)
+// Tl is a table that stores 2^fl (32 entries) rounded to
+// double extended precision (only mantissa is stored)
+//
+// 10^x is approximated as
+// 2^K * Th [ f ] * Tl [ f ] * (1+c1*e+c1*r+c2*r^2+c3*r^3+c4*r^4),
+// where e= (x*log2(10)_hi-RN(x*log2(10)_hi))+log2(10)_lo*x
+
+// Note there are only 22 non-zero values that produce an exact result:
+//  1.0, 2.0, ... 22.0.
+// We test for these cases and use s1 to avoid setting the inexact flag.
+
+// Special values
+//==============================================================
+// exp10(0)= 1

+// History
+//==============================================================
+// 08/25/00 Initial version
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 09/06/02 Improved performance and accuracy; no inexact flags on exact cases
+// 01/29/03 Added missing } to bundle templates
+// 12/16/04 Call error handling on underflow.
+// 03/31/05 Reformatted delimiters between data tables
+//
+// API
+//==============================================================
+// float exp10f(float)
+//
+// Overview of operation
+//==============================================================
+// Background
+//
+// Implementation
+//
+// Let x= (K + fh + fl + r)/log2(10), where
+// K is an integer, fh= 0.b1 b2 b3 b4 b5,
+// fl= 2^{-5}* 0.b6 b7 b8 b8 b10 (fh, fl >= 0),
+// and |r|<2^{-11}
+// Th is a table that stores 2^fh (32 entries) rounded to
+// double extended precision (only mantissa is stored)
+// Tl is a table that stores 2^fl (32 entries) rounded to
+// double extended precision (only mantissa is stored)
+//
+// 10^x is approximated as
+// 2^K * Th [ f ] * Tl [ f ] * (1+c1*r+c2*r^2)
+
+// Note there are only 10 non-zero values that produce an exact result:
+//  1.0, 2.0, ... 10.0.
+// We test for these cases and use s1 to avoid setting the inexact flag.
+
+// Special values
+//==============================================================
+// exp10(0)= 1
+// exp10(+inf)= inf
+// exp10(-inf)= 0
+//

+// History
+//==============================================================
+// 08/25/00 Initial version
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 02/06/03 Reordered header: .section, .global, .proc, .align
+// 05/08/03 Reformatted assembly source; corrected overflow result for round to
+//          -inf and round to zero; exact results now don't set inexact flag
+// 12/16/04 Call error handling on underflow.

+// API
+//==============================================================

+//
+// Overview of operation
+//==============================================================
+// Background
+//
+// Implementation
+//
+// Let x= (K + f + r)/log2(10), where
+// K is an integer, f= 0.b1 b2... b8 (f>= 0),
+// and |r|<2^{-9}
+// T is a table that stores 2^f (256 entries) rounded to
+// double extended precision (only mantissa is stored)
+// D stores (2^f/T [ f ] - 1), rounded to single precision
+//
+// 10^x is approximated as
+// 2^K * T [ f ] * ((1+c1*r+c2*r^2+...+c6*r^6)*(1+c1*e)+D [ f ] ),
+// where e= log2(10)_lo*x+(log2(10)_hi*x-RN(log2(10)_hi*x))
+//
+
+
+
+// Special values

+// exp10(+inf)= inf
+// exp10(-inf)= 0

+//==============================================================
+// 08/25/00  Initial version
+// 05/20/02  Cleaned up namespace and sf0 syntax
+// 09/05/02  Improved performance
+// 01/17/03  Fixed to call error support when x=1024.0
+// 03/31/05  Reformatted delimiters between data tables

+//
+// Overview of operation
+//==============================================================
+// Background
+//
+// Implementation
+//
+// Let x= (K + fh + fl + r), where
+// K is an integer, fh= 0.b1 b2 b3 b4 b5,
+// fl= 2^{-5}* 0.b6 b7 b8 b8 b10 (fh, fl >= 0),
+// and |r|<2^{-11}
+// Th is a table that stores 2^fh (32 entries) rounded to
+// double extended precision (only mantissa is stored)
+// Tl is a table that stores 2^fl (32 entries) rounded to
+// double extended precision (only mantissa is stored)
+//
+// 2^x is approximated as
+// 2^K * Th [ f ] * Tl [ f ] * (1+c1*r+c2*r^2+c3*r^3+c4*r^4)
+
+// Note: We use the following trick to speed up conversion from FP to integer:
+//
+// Let  x = K + r, where K is an integer, and  |r| <= 0.5
+// Let N be the number of significand bits for the FP format used
+//   ( N=64 for double-extended, N=53 for double)
+//
+// Then let y = 1.5 * 2^(N-1)  +  x    for RN mode
+//          K = y -  1.5 * 2^(N-1)
+//          r  = x - K
+//
+// If we want to obtain the integer part and the first m fractional bits of x,
+// we can use the same trick, but with a constant of  1.5 * 2^(N-1-m):
+//
+// Let x = K + f + r
+// f = 0.b_1 b_2 ... b_m
+// |r| <= 2^(-m-1)
+//
+// Then let y = 1.5 * 2^(N-1-m)  +  x    for RN mode
+//          (K+f) = y -  1.5 * 2^(N-1-m)
+//          r  = x - K

+// History
+//==============================================================
+// 08/25/00  Initial version
+// 05/20/02  Cleaned up namespace and sf0 syntax
+// 09/05/02  Improved performance and accuracy
+// 01/17/03  Fixed to call error support when x=128.0
+// 03/31/05  Reformatted delimiters between data tables
+//
+// API
+//==============================================================

+//
+// Overview of operation
+//==============================================================
+// Background
+//
+// Implementation
+//
+// Let x= (K + fh + fl + r), where
+// K is an integer, fh= 0.b1 b2 b3 b4 b5,
+// fl= 2^{-5}* 0.b6 b7 b8 b8 b10 (fh, fl >= 0),
+// and |r|<2^{-11}
+// Th is a table that stores 2^fh (32 entries) rounded to
+// double extended precision (only mantissa is stored)
+// Tl is a table that stores 2^fl (32 entries) rounded to
+// double extended precision (only mantissa is stored)
+//
+// 2^x is approximated as
+// 2^K * Th [ f ] * Tl [ f ] * (1+c1*r+c2*r^2)
+
+// Note: We use the following trick to speed up conversion from FP to integer:
+//
+// Let  x = K + r, where K is an integer, and  |r| <= 0.5
+// Let N be the number of significand bits for the FP format used
+//   ( N=64 for double-extended, N=53 for double)
+//
+// Then let y = 1.5 * 2^(N-1)  +  x    for RN mode
+//          K = y -  1.5 * 2^(N-1)
+//          r  = x - K
+//
+// If we want to obtain the integer part and the first m fractional bits of x,
+// we can use the same trick, but with a constant of  1.5 * 2^(N-1-m):
+//
+// Let x = K + f + r
+// f = 0.b_1 b_2 ... b_m
+// |r| <= 2^(-m-1)
+//
+// Then let y = 1.5 * 2^(N-1-m)  +  x    for RN mode
+//          (K+f) = y -  1.5 * 2^(N-1-m)
+//          r  = x - K

+// Overview of operation
+//*********************************************************************
+// Take the input x. w is "how many log2/128 in x?"
+//  w = x * 64/log2
+//  NJ = int(w)
+//  x = NJ*log2/64 + R
+
+//  NJ = 64*n + j
+//  x = n*log2 + (log2/64)*j + R
+//
+//  So, exp(x) = 2^n * 2^(j/64)* exp(R)
+//
+//  T =  2^n * 2^(j/64)
+//       Construct 2^n
+//       Get 2^(j/64) table
+//           actually all the entries of 2^(j/64) table are stored in DP and
+//           with exponent bits set to 0 -> multiplication on 2^n can be
+//           performed by doing logical "or" operation with bits presenting 2^n
+
+//  exp(R) = 1 + (exp(R) - 1)
+//  P = exp(R) - 1 approximated by Taylor series of 3rd degree
+//      P = A3*R^3 + A2*R^2 + R, A3 = 1/6, A2 = 1/2
+//
+
+//  The final result is reconstructed as follows
+//  exp(x) = T + T*P

+// 04/04/00 Unwind support added
+// 08/15/00 Bundle added after call to __libm_error_support to properly

+// History
+//====================================================================
+// 02/02/00 Initial version
+// 03/02/00 New Algorithm
+// 04/04/00 Unwind support added
+// 08/15/00 Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 11/28/00 Set FR_Y to f9
+// 03/11/02 Fixed flags for fmodf(qnan,zero)
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 02/10/03 Reordered header: .section, .global, .proc, .align
+// 04/28/03 Fix: fmod(sNaN,0) no longer sets errno

+//  |i|<|a/b| and |a/b-i|<1
+
+// Algorithm
+//====================================================================
+// a). if |a|<|b|, return a
+// b). get quotient and reciprocal overestimates accurate to
+//     33 bits (q2,y2)
+// c). if the exponent difference (exponent(a)-exponent(b))
+//     is less than 32, truncate quotient to integer and
+//     finish in one iteration
+// d). if exponent(a)-exponent(b)>=32 (q2>=2^32)
+//     round quotient estimate to single precision (k=RN(q2)),
+//     calculate partial remainder (a'=a-k*b),
+//     get quotient estimate (a'*y2), and repeat from c).

+// History:
+// 02/02/00 hand-optimized
+// 04/04/00 Unwind support added
+// 06/26/00 new version
+// 08/15/00 Bundle added after call to __libm_error_support to properly

+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 02/10/03 Reordered header: .section, .global, .proc, .align

+// 05/26/00 Fix bug when x a double-extended denormal;
+//          if x=0 call error routine, per C9X
+// 08/15/00 Bundle added after call to __libm_error_support to properly

+//==============================================================
+// int ilogbl( long double x );
+//
+// Overview of operation
+//==============================================================
+// The ilogbl function extracts the exponent of x as an integer
+// and returns it in r8
+//
+// ilogbl is similar to logbl but differs in the following ways:
+//         +-inf
+//            ilogbl: returns INT_MAX
+//             logbl: returns +inf
+//         Nan  returns FP_LOGBNAN (which is either INT_MAX or INT_MIN)
+//            ilogbl: returns INT_MAX (7fffffff)
+//             logbl: returns QNAN (quietized SNAN)
+//         0    returns FP_ILOGB0 (which is either INT_MIN or -INT_MAX)
+//            ilogbl: returns -INT_MAX (80000001)
+//             logbl: returns -inf, raises the divide-by-zero exception,
+//                   and calls libm_error_support to set domain error
+//
+// Registers used

+// Overview of operation
+//==============================================================
+// Background
+// ----------
+//
+// This algorithm is based on fact that
+// log(a b) = log(a) + log(b).
+// In our case we have x = 2^N f, where 1 <= f < 2.
+// So
+//   log(x) = log(2^N f) = log(2^N) + log(f) = n*log(2) + log(f)
+//
+// To calculate log(f) we do following
+//   log(f) = log(f * frcpa(f) / frcpa(f)) =
+//          = log(f * frcpa(f)) + log(1/frcpa(f))
+//
+// According to definition of IA-64's frcpa instruction it's a
+// floating point that approximates 1/f using a lookup on the
+// top of 8 bits of the input number's significand with relative
+// error < 2^(-8.886). So we have following
+//
+// |(1/f - frcpa(f)) / (1/f))| = |1 - f*frcpa(f)| < 1/256
+//
+// and
+//
+// log(f) = log(f * frcpa(f)) + log(1/frcpa(f)) =
+//        = log(1 + r) + T
+//
+// The first value can be computed by polynomial P(r) approximating
+// log(1 + r) on |r| < 1/256 and the second is precomputed tabular
+// value defined by top 8 bit of f.
+//
+// Finally we have that  log(x) ~ (N*log(2) + T) + P(r)
+//
+// Note that if input argument is close to 1.0 (in our case it means
+// that |1 - x| < 1/256) we can use just polynomial approximation
+// because x = 2^0 * f = f = 1 + r and
+// log(x) = log(1 + r) ~ P(r)
+//
+//
+// To compute log10(x) we use the simple identity
+//
+//  log10(x) = log(x)/log(10)
+//
+// so we have that
+//
+//  log10(x) = (N*log(2) + T  + log(1+r)) / log(10) =
+//           = N*(log(2)/log(10)) + (T/log(10)) + log(1 + r)/log(10)
+//
+//
+// Implementation
+// --------------
+// It can be seen that formulas for log and log10 differ from one another
+// only by coefficients and tabular values. Namely as log as log10 are
+// calculated as (N*L1 + T) + L2*Series(r) where in case of log
+//   L1 = log(2)
+//   T  = log(1/frcpa(x))
+//   L2 = 1.0
+// and in case of log10
+//   L1 = log(2)/log(10)
+//   T  = log(1/frcpa(x))/log(10)
+//   L2 = 1.0/log(10)
+//
+// So common code with two different entry points those set pointers
+// to the base address of coresponding data sets containing values
+// of L2,T and prepare integer representation of L1 needed for following
+// setf instruction.
+//
+// Note that both log and log10 use common approximation polynomial
+// it means we need only one set of coefficients of approximation.
+//
+//
+// 1. |x-1| >= 1/256
+//   InvX = frcpa(x)
+//   r = InvX*x - 1
+//   P(r) = r*((r*A3 - A2) + r^4*((A4 + r*A5) + r^2*(A6 + r*A7)),
+//   all coefficients are calcutated in quad and rounded to double
+//   precision. A7,A6,A5,A4 are stored in memory whereas A3 and A2
+//   created with setf.
+//
+//   N = float(n) where n is true unbiased exponent of x
+//
+//   T is tabular value of log(1/frcpa(x)) calculated in quad precision
+//   and represented by two floating-point numbers 64-bit Thi and 32-bit Tlo.
+//   To load Thi,Tlo we get bits from 55 to 62 of register format significand
+//   as index and calculate two addresses
+//     ad_Thi = Thi_table_base_addr + 8 * index
+//     ad_Tlo = Tlo_table_base_addr + 4 * index
+//
+//   L2 (1.0 or 1.0/log(10) depending on function) is calculated in quad
+//   precision and rounded to double extended; it's loaded from memory.
+//
+//   L1 (log(2) or log10(2) depending on function) is calculated in quad
+//   precision and represented by two floating-point 64-bit numbers L1hi,L1lo
+//   stored in memory.
+//
+//   And final result = ((L1hi*N + Thi) + (N*L1lo + Tlo)) + L2*P(r)
+//
+//
+// 2. |x-1| < 1/256
+//   r = x - 1
+//   P(r) = r*((r*A3 - A2) + r^4*((A4 + r*A5) + r^2*(A6 + r*A7)),
+//   A7,A6,A5A4,A3,A2 are the same as in case |x-1| >= 1/256
+//
+//   And final results
+//     log(x)   = P(r)
+//     log10(x) = L2*P(r)
+//
+// 3. How we define is input argument such that |x-1| < 1/256 or not.
+//
+//    To do it we analyze biased exponent and integer representation of
+//    input argument
+//
+//      a) First we test is biased exponent equal to 0xFFFE or 0xFFFF (i.e.
+//         we test is 0.5 <= x < 2). This comparison can be performed using
+//         unsigned version of cmp instruction in such a way
+//         biased_exponent_of_x - 0xFFFE < 2
+//
+//
+//      b) Second (in case when result of a) is true) we need to compare x
+//         with 1-1/256 and 1+1/256 or in double precision memory representation
+//         with 0x3FEFE00000000000 and 0x3FF0100000000000 correspondingly.
+//         This comparison can be made like in a), using unsigned
+//         version of cmp i.e. ix - 0x3FEFE00000000000 < 0x0000300000000000.
+//         0x0000300000000000 is difference between 0x3FF0100000000000 and
+//         0x3FEFE00000000000
+//
+//    Note: NaT, any NaNs, +/-INF, +/-0, negatives and unnormalized numbers are
+//          filtered and processed on special branches.

+// double log2(double)
+//
+// Overview of operation
+//=================================================================
+// Background
+//
+// Implementation
+//
+// Let x = 2^l * m, where     m=1.b1 b2 ... b8 b9 ... b52
+//     y=frcpa(m),   r=m*y-1, f=b1 b2 .. b8 (table index)
+// j=0 if f<128; j=1 if f>=128
+// T is a table that stores log2(1/y) (in entries 1..255) rounded to
+//   double extended precision; f is used as an index; T[255]=0
+//
+// If f=0 and b9=0, r is set to 2^{-8}* 0.b9 b10 ... b52 = m-1 (fractional part of m),
+//                  and 0 is used instead of T[0]
+//                  (polynomial evaluation only, for m=1+r, 0<=r<2^{-9})
+// If f=255, r is set to (m-2)/2  (T[255]=0, and only polynomial evaluation is used
+//                                 for m=2(1-r'), 0<=r'<2^{-9})
+//
+// log2(x) is approximated as
+//     (l-j) + T[f] + (c1*r+c2*r^2+...+c7*r^7), if f>0
+//
+
+
+// Special values
+//=================================================================
+//  log2(0)=-inf, raises Divide by Zero
+//  log2(+inf)=inf
+//  log2(x)=NaN,  raises Invalid if x<0
+//
+
+
+// Registers used

+// float log2f(float)
+//
+// Overview of operation
+//==============================================================
+// Background
+//
+// Implementation
+//
+// Let x = 2^l * m, where     m=1.b1 b2 ... b8 b9 ... b52
+//     y=frcpa(m),   r=m*y-1, f=b1 b2 .. b8 (table index)
+// j=0 if f<128; j=1 if f>=128
+// T is a table that stores log2(1/y) (in entries 1..255) rounded to
+//   double extended precision; f is used as an index; T[255]=0
+//
+// If f=0 and b9=0, r is set to 2^{-8}* 0.b9 b10 ... b52 = m-1 (fractional part of m),
+//                  and 0 is used instead of T[0]
+//                  (polynomial evaluation only, for m=1+r, 0<=r<2^{-9})
+// If f=255, r is set to (m-2)/2  (T[255]=0, and only polynomial evaluation is used
+//                                 for m=2(1-r'), 0<=r'<2^{-9})
+//
+// log2f(x) is approximated as
+//     (l-j) + T[f] + (c1*r+c2*r^2+...+c6*r^6), if f>0
+//
+
+
+// Special values
+//==============================================================
+//  log2f(0)=-inf, raises Divide by Zero
+//  log2f(+inf)=inf
+//  log2f(x)=NaN,  raises Invalid if x<0
+//
+

+//
+// Overview of operation
+//==============================================================
+// Background
+//
+// Implementation
+//
+// Let x = 2^l * m, where     m=1.b1 b2 ... b8 b9 ... b52
+//     y=frcpa(m),   r=m*y-1, f=b1 b2 .. b8
+// T_hi is a table that stores the 24 most significant bits of log2(1/y)
+// (in entries 1..255) in single precision format
+// T_low is a table that stores (log2(1/y)-T_high), rounded to double
+// precision
+//
+// f is used as an index; T_high[255]=T_low[255]=0
+//
+// If f=0 and b9=0, r is set to 2^{-8}* 0.b9 b10 ... b52 = m-1 (fractional part of m),
+//                  and 0 is used instead of T_high[0], T_low[0]
+//                  (polynomial evaluation only, for m=1+r, 0<=r<2^{-9})
+// If f=255, r is set to (m-2)/2  (T[255]=0, and only polynomial evaluation is used
+//                                 for m=2(1-r'), 0<=r'<2^{-9})
+//
+// If 2^{-9}<=m<2-2^{-8} or (input not near 1), let C1r=(2^{16}+C1*r)-2^{16}
+//                       and let E=((RN(m*y)-1)-r)+(m*y-RN(m*y))
+// Else let C1r=C1*r (rounded to 64 significant bits)  and let  E=0
+//
+// Let D=C1*r-C1r
+//
+//
+// log2l(x) is approximated as
+//     (l+T_high[f]+C1r) + (D+r*(c1+c2*r+c3*r^2...+c8*r^7)+(T_low[f]+C_1*E))
+//
+
+
+// Special values
+//==============================================================
+//  log2l(0)=-inf, raises Divide by Zero
+//  log2l(+inf)=inf
+//  log2l(x)=NaN,  raises Invalid if x<0

+// Overview of operation
+//==============================================================
+// Background
+// ----------
+//
+// This algorithm is based on fact that
+// log(a b) = log(a) + log(b).
+//
+// In our case we have x = 2^N f, where 1 <= f < 2.
+// So
+//   log(x) = log(2^N f) = log(2^N) + log(f) = n*log(2) + log(f)
+//
+// To calculate log(f) we do following
+//   log(f) = log(f * frcpa(f) / frcpa(f)) =
+//          = log(f * frcpa(f)) + log(1/frcpa(f))
+//
+// According to definition of IA-64's frcpa instruction it's a
+// floating point that approximates 1/f using a lookup on the
+// top of 8 bits of the input number's significand with relative
+// error < 2^(-8.886). So we have following
+//
+// |(1/f - frcpa(f)) / (1/f))| = |1 - f*frcpa(f)| < 1/256
+//
+// and
+//
+// log(f) = log(f * frcpa(f)) + log(1/frcpa(f)) =
+//        = log(1 + r) + T
+//
+// The first value can be computed by polynomial P(r) approximating
+// log(1 + r) on |r| < 1/256 and the second is precomputed tabular
+// value defined by top 8 bit of f.
+//
+// Finally we have that  log(x) ~ (N*log(2) + T) + P(r)
+//
+// Note that if input argument is close to 1.0 (in our case it means
+// that |1 - x| < 1/256) we can use just polynomial approximation
+// because x = 2^0 * f = f = 1 + r and
+// log(x) = log(1 + r) ~ P(r)
+//
+//
+// To compute log10(x) we just use identity:
+//
+//  log10(x) = log(x)/log(10)
+//
+// so we have that
+//
+//  log10(x) = (N*log(2) + T  + log(1+r)) / log(10) =
+//           = N*(log(2)/log(10)) + (T/log(10)) + log(1 + r)/log(10)
+//
+//
+// Implementation
+// --------------
+// It can be seen that formulas for log and log10 differ from one another
+// only by coefficients and tabular values. Namely as log as log10 are
+// calculated as (N*L1 + T) + L2*Series(r) where in case of log
+//   L1 = log(2)
+//   T  = log(1/frcpa(x))
+//   L2 = 1.0
+// and in case of log10
+//   L1 = log(2)/log(10)
+//   T  = log(1/frcpa(x))/log(10)
+//   L2 = 1.0/log(10)
+//
+// So common code with two different entry points those set pointers
+// to the base address of coresponding data sets containing values
+// of L2,T and prepare integer representation of L1 needed for following
+// setf instruction can be used.
+//
+// Note that both log and log10 use common approximation polynomial
+// it means we need only one set of coefficients of approximation.
+//
+// 1. Computation of log(x) for |x-1| >= 1/256
+//   InvX = frcpa(x)
+//   r = InvX*x - 1
+//   P(r) = r*((1 - A2*r) + r^2*(A3 - A4*r)) = r*P2(r),
+//   A4,A3,A2 are created with setf inctruction.
+//   We use Taylor series and so A4 = 1/4, A3 = 1/3,
+//   A2 = 1/2 rounded to double.
+//
+//   N = float(n) where n is true unbiased exponent of x
+//
+//   T is tabular value of log(1/frcpa(x)) calculated in quad precision
+//   and rounded to double. To T we get bits from 55 to 62 of register
+//   format significand of x and calculate address
+//     ad_T = table_base_addr + 8 * index
+//
+//   L2 (1.0 or 1.0/log(10) depending on function) is calculated in quad
+//   precision and rounded to double; it's loaded from memory
+//
+//   L1 (log(2) or log10(2) depending on function) is calculated in quad
+//   precision and rounded to double; it's created with setf.
+//
+//   And final result = P2(r)*(r*L2) + (T + N*L1)
+//
+//
+// 2. Computation of log(x) for |x-1| < 1/256
+//   r = x - 1
+//   P(r) = r*((1 - A2*r) + r^2*(A3 - A4*r)) = r*P2(r),
+//   A4,A3,A2 are the same as in case |x-1| >= 1/256
+//
+//   And final result = P2(r)*(r*L2)
+//
+// 3. How we define is input argument such that |x-1| < 1/256 or not.
+//
+//    To do it we analyze biased exponent and significand of input argment.
+//
+//      a) First we test is biased exponent equal to 0xFFFE or 0xFFFF (i.e.
+//         we test is 0.5 <= x < 2). This comparison can be performed using
+//         unsigned version of cmp instruction in such a way
+//         biased_exponent_of_x - 0xFFFE < 2
+//
+//
+//      b) Second (in case when result of a) is true) we need to compare x
+//         with 1-1/256 and 1+1/256 or in register format representation with
+//         0xFFFEFF00000000000000 and 0xFFFF8080000000000000 correspondingly.
+//         As far as biased exponent of x here can be equal only to 0xFFFE or
+//         0xFFFF we need to test only last bit of it. Also signifigand always
+//         has implicit bit set to 1 that can be exluded from comparison.
+//         Thus it's quite enough to generate 64-bit integer bits of that are
+//         ix[63] = biased_exponent_of_x[0] and ix[62-0] = significand_of_x[62-0]
+//         and compare it with 0x7F00000000000000 and 0x80800000000000000 (those
+//         obtained like ix from register representatinos of 255/256 and
+//         257/256). This comparison can be made like in a), using unsigned
+//         version of cmp i.e. ix - 0x7F00000000000000 < 0x0180000000000000.
+//         0x0180000000000000 is difference between 0x80800000000000000 and
+//         0x7F00000000000000.
+//
+//    Note: NaT, any NaNs, +/-INF, +/-0, negatives and unnormalized numbers are
+//          filtered and processed on special branches.

+// Overview
+//
+// The method consists of two cases.
+//
+// If      |X-1| < 2^(-7)	use case log_near1;
+// else      			use case log_regular;
+//
+// Case log_near1:
+//
+//   logl( 1 + X ) can be approximated by a simple polynomial
+//   in W = X-1. This polynomial resembles the truncated Taylor
+//   series W - W^/2 + W^3/3 - ...
+//
+// Case log_regular:
+//
+//   Here we use a table lookup method. The basic idea is that in
+//   order to compute logl(Arg) for an argument Arg in [1,2), we
+//   construct a value G such that G*Arg is close to 1 and that
+//   logl(1/G) is obtainable easily from a table of values calculated
+//   beforehand. Thus
+//
+//      logl(Arg) = logl(1/G) + logl(G*Arg)
+//      	 = logl(1/G) + logl(1 + (G*Arg - 1))
+//
+//   Because |G*Arg - 1| is small, the second term on the right hand
+//   side can be approximated by a short polynomial. We elaborate
+//   this method in four steps.
+//
+//   Step 0: Initialization
+//
+//   We need to calculate logl( X ). Obtain N, S_hi such that
+//
+//      X = 2^N * S_hi 	exactly
+//
+//   where S_hi in [1,2)
+//
+//   Step 1: Argument Reduction
+//
+//   Based on S_hi, obtain G_1, G_2, G_3 from a table and calculate
+//
+//      G := G_1 * G_2 * G_3
+//      r := (G * S_hi - 1)
+//
+//   These G_j's have the property that the product is exactly
+//   representable and that |r| < 2^(-12) as a result.
+//

+//
+//       W := X - 1
+//       Wsq := W * W

+//       W6  := W4*Wsq
+//       Y_hi := W + Wsq*(P_1 + W*(P_2 + W*(P_3 + W*P_4))
+//       Y_lo := W6*(P_5 + W*(P_6 + W*(P_7 + W*P_8)))
+//
+// Case log_regular:
+//
+// We present the algorithm in four steps.
+//
+//   Step 0. Initialization
+//   ----------------------
+//
+//   Z := X
+//   N := unbaised exponent of Z
+//   S_hi := 2^(-N) * Z
+//
+//   Step 1. Argument Reduction
+//   --------------------------
+//
+//   Let
+//
+//      Z = 2^N * S_hi = 2^N * 1.d_1 d_2 d_3 ... d_63
+//
+//   We obtain G_1, G_2, G_3 by the following steps.
+//
+//
+//      Define		X_0 := 1.d_1 d_2 ... d_14. This is extracted
+//      		from S_hi.
+//
+//      Define		A_1 := 1.d_1 d_2 d_3 d_4. This is X_0 truncated
+//      		to lsb = 2^(-4).
+//
+//      Define		index_1 := [ d_1 d_2 d_3 d_4 ].
+//
+//      Fetch 		Z_1 := (1/A_1) rounded UP in fixed point with
+//      fixed point	lsb = 2^(-15).
+//      		Z_1 looks like z_0.z_1 z_2 ... z_15
+//      	        Note that the fetching is done using index_1.
+//      		A_1 is actually not needed in the implementation
+//      		and is used here only to explain how is the value
+//      		Z_1 defined.
+//
+//      Fetch		G_1 := (1/A_1) truncated to 21 sig. bits.
+//      floating pt.	Again, fetching is done using index_1. A_1
+//      		explains how G_1 is defined.
+//
+//      Calculate	X_1 := X_0 * Z_1 truncated to lsb = 2^(-14)
+//      		     = 1.0 0 0 0 d_5 ... d_14
+//      		This is accomplised by integer multiplication.
+//      		It is proved that X_1 indeed always begin
+//      		with 1.0000 in fixed point.
+//
+//
+//      Define		A_2 := 1.0 0 0 0 d_5 d_6 d_7 d_8. This is X_1
+//      		truncated to lsb = 2^(-8). Similar to A_1,
+//      		A_2 is not needed in actual implementation. It
+//      		helps explain how some of the values are defined.
+//
+//      Define		index_2 := [ d_5 d_6 d_7 d_8 ].
+//
+//      Fetch 		Z_2 := (1/A_2) rounded UP in fixed point with
+//      fixed point	lsb = 2^(-15). Fetch done using index_2.
+//      		Z_2 looks like z_0.z_1 z_2 ... z_15
+//
+//      Fetch		G_2 := (1/A_2) truncated to 21 sig. bits.
+//      floating pt.
+//
+//      Calculate	X_2 := X_1 * Z_2 truncated to lsb = 2^(-14)
+//      		     = 1.0 0 0 0 0 0 0 0 d_9 d_10 ... d_14
+//      		This is accomplised by integer multiplication.
+//      		It is proved that X_2 indeed always begin
+//      		with 1.00000000 in fixed point.
+//
+//
+//      Define		A_3 := 1.0 0 0 0 0 0 0 0 d_9 d_10 d_11 d_12 d_13 1.
+//      		This is 2^(-14) + X_2 truncated to lsb = 2^(-13).
+//
+//      Define		index_3 := [ d_9 d_10 d_11 d_12 d_13 ].
+//
+//      Fetch		G_3 := (1/A_3) truncated to 21 sig. bits.
+//      floating pt.	Fetch is done using index_3.
+//
+//      Compute		G := G_1 * G_2 * G_3.
+//
+//      This is done exactly since each of G_j only has 21 sig. bits.
+//
+//      Compute
+//
+//      	r := (G*S_hi - 1)
+//
+//
+//  Step 2. Approximation
+//  ---------------------
+//
+//   This step computes an approximation to logl( 1 + r ) where r is the
+//   reduced argument just obtained. It is proved that |r| <= 1.9*2^(-13);
+//   thus logl(1+r) can be approximated by a short polynomial:
+//
+//      logl(1+r) ~=~ poly = r + Q1 r^2 + ... + Q4 r^5
+//
+//
+//  Step 3. Reconstruction
+//  ----------------------
+//
+//   This step computes the desired result of logl(X):
+//
+//      logl(X)  =   logl( 2^N * S_hi )
+//      	  =   N*logl(2) + logl( S_hi )
+//      	  =   N*logl(2) + logl(1/G) +
+//      	      logl(1 + G*S_hi - 1 )
+//
+//   logl(2), logl(1/G_j) are stored as pairs of (single,double) numbers:
+//   log2_hi, log2_lo, log1byGj_hi, log1byGj_lo. The high parts are
+//   single-precision numbers and the low parts are double precision
+//   numbers. These have the property that
+//
+//      N*log2_hi + SUM ( log1byGj_hi )
+//
+//   is computable exactly in double-extended precision (64 sig. bits).
+//   Finally
+//
+//      Y_hi := N*log2_hi + SUM ( log1byGj_hi )
+//      Y_lo := poly_hi + [ poly_lo +
+//              ( SUM ( log1byGj_lo ) + N*log2_lo ) ]

+// History
+//==============================================================
+// 02/02/00 Initial version
+// 02/03/00 Added p12 to definite over/under path. With odd power we did not
+//          maintain the sign of x in this path.
+// 04/04/00 Unwind support added
+// 04/19/00 pow(+-1,inf) now returns NaN
+//          pow(+-val, +-inf) returns 0 or inf, but now does not call error
+//          support
+//          Added s1 to fcvt.fx because invalid flag was incorrectly set.
+// 08/15/00 Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 09/07/00 Improved performance by eliminating bank conflicts and other stalls,
+//          and tweaking the critical path
+// 09/08/00 Per c99, pow(+-1,inf) now returns 1, and pow(+1,nan) returns 1
+// 09/28/00 Updated NaN**0 path
+// 01/20/01 Fixed denormal flag settings.
+// 02/13/01 Improved speed.
+// 03/19/01 Reordered exp polynomial to improve speed and eliminate monotonicity
+//          problem in round up, down, and to zero modes.  Also corrected
+//          overflow result when x negative, y odd in round up, down, zero.
+// 06/14/01 Added brace missing from bundle
+// 12/10/01 Corrected case where x negative, 2^52 <= |y| < 2^53, y odd integer.
+// 12/20/01 Fixed monotonity problem in round to nearest.
+// 02/08/02 Fixed overflow/underflow cases that were not calling error support.
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 08/29/02 Improved Itanium 2 performance
+// 09/21/02 Added branch for |y*log(x)|<2^-11 to fix monotonicity problems.
+// 02/10/03 Reordered header: .section, .global, .proc, .align
+// 03/31/05 Reformatted delimiters between data tables
+//

+//
+// Overview of operation
+//==============================================================
+//
+// Three steps...
+// 1. Log(x)
+// 2. y Log(x)
+// 3. exp(y log(x))
+//
+// This means we work with the absolute value of x and merge in the sign later.
+//      Log(x) = G + delta + r -rsq/2 + p
+// G,delta depend on the exponent of x and table entries. The table entries are
+// indexed by the exponent of x, called K.
+//
+// The G and delta come out of the reduction; r is the reduced x.
+//
+// B = frcpa(x)
+// xB-1 is small means that B is the approximate inverse of x.
+//
+//      Log(x) = Log( (1/B)(Bx) )
+//             = Log(1/B) + Log(Bx)
+//             = Log(1/B) + Log( 1 + (Bx-1))
+//
+//      x  = 2^K 1.x_1x_2.....x_52
+//      B= frcpa(x) = 2^-k Cm
+//      Log(1/B) = Log(1/(2^-K Cm))
+//      Log(1/B) = Log((2^K/ Cm))
+//      Log(1/B) = K Log(2) + Log(1/Cm)
+//
+//      Log(x)   = K Log(2) + Log(1/Cm) + Log( 1 + (Bx-1))
+//
+// If you take the significand of x, set the exponent to true 0, then Cm is
+// the frcpa. We tabulate the Log(1/Cm) values. There are 256 of them.
+// The frcpa table is indexed by 8 bits, the x_1 thru x_8.
+// m = x_1x_2...x_8 is an 8-bit index.
+//
+//      Log(1/Cm) = log(1/frcpa(1+m/256)) where m goes from 0 to 255.
+//
+// We tabluate as two doubles, T and t, where T +t is the value itself.
+//
+//      Log(x)   = (K Log(2)_hi + T) + (Log(2)_hi + t) + Log( 1 + (Bx-1))
+//      Log(x)   =  G + delta           + Log( 1 + (Bx-1))
+//
+// The Log( 1 + (Bx-1)) can be calculated as a series in r = Bx-1.
+//
+//      Log( 1 + (Bx-1)) = r - rsq/2 + p
+//
+// Then,
+//
+//      yLog(x) = yG + y delta + y(r-rsq/2) + yp
+//      yLog(x) = Z1 + e3      + Z2         + Z3 + (e2 + e3)
+//
+//
+//     exp(yLog(x)) = exp(Z1 + Z2 + Z3) exp(e1 + e2 + e3)
+//
+//
+//       exp(Z3) is another series.
+//       exp(e1 + e2 + e3) is approximated as f3 = 1 + (e1 + e2 + e3)
+//
+//       Z1 (128/log2) = number of log2/128 in Z1 is N1
+//       Z2 (128/log2) = number of log2/128 in Z2 is N2
+//
+//       s1 = Z1 - N1 log2/128
+//       s2 = Z2 - N2 log2/128
+//

+//       N = N1 + N2
+//

+//       exp(Z)       = exp(s) exp(N log2/128)
+//
+//       exp(r)       = exp(Z - N log2/128)
+//
+//      r = s + d = (Z - N (log2/128)_hi) -N (log2/128)_lo
+//                =  Z - N (log2/128)

+//      n log2/128 = n_7n_6n_5 16 log2/128 + n_4n_3n_2n_1 log2/128
+//      n log2/128 = n_7n_6n_5 log2/8 + n_4n_3n_2n_1 log2/128
+//      n log2/128 = I2 log2/8 + I1 log2/128

+//      exp(Z)    = exp(s) (1+d1) (1+d2)(2^M) 2^I2/8 2^I1/128
+//      exp(Z)    = exp(s) f1 f2 (2^M) 2^I2/8 2^I1/128
+//
+// I1, I2 are table indices. Use a series for exp(s).
+// Then get exp(Z)
+//
+//     exp(yLog(x)) = exp(Z1 + Z2 + Z3) exp(e1 + e2 + e3)
+//     exp(yLog(x)) = exp(Z) exp(Z3) f3
+//     exp(yLog(x)) = exp(Z)f3 exp(Z3)
+//     exp(yLog(x)) = A exp(Z3)
+//
+// We actually calculate exp(Z3) -1.
+// Then,
+//     exp(yLog(x)) = A + A( exp(Z3)   -1)
+//
+
+// Table Generation
+//==============================================================
+
+// The log values
+// ==============
+// The operation (K*log2_hi) must be exact. K is the true exponent of x.
+// If we allow gradual underflow (denormals), K can be represented in 12 bits
+// (as a two's complement number). We assume 13 bits as an engineering
+// precaution.
+//
+//           +------------+----------------+-+
+//           |  13 bits   | 50 bits        | |
+//           +------------+----------------+-+
+//           0            1                66
+//                        2                34
+//
+// So we want the lsb(log2_hi) to be 2^-50
+// We get log2 as a quad-extended (15-bit exponent, 128-bit significand)
+//
+//      0 fffe b17217f7d1cf79ab c9e3b39803f2f6af (4...)
+//
+// Consider numbering the bits left to right, starting at 0 thru 127.
+// Bit 0 is the 2^-1 bit; bit 49 is the 2^-50 bit.
+//
+//  ...79ab
+//     0111 1001 1010 1011
+//     44
+//     89
+//
+// So if we shift off the rightmost 14 bits, then (shift back only
+// the top half) we get
+//
+//      0 fffe b17217f7d1cf4000 e6af278ece600fcb dabc000000000000
+//
+// Put the right 64-bit signficand in an FR register, convert to double;
+// it is exact. Put the next 128 bits into a quad register and round to double.
+// The true exponent of the low part is -51.
+//
+// hi is 0 fffe b17217f7d1cf4000
+// lo is 0 ffcc e6af278ece601000
+//
+// Convert to double memory format and get
+//
+// hi is 0x3fe62e42fefa39e8
+// lo is 0x3cccd5e4f1d9cc02
+//
+// log2_hi + log2_lo is an accurate value for log2.
+//
+//
+// The T and t values
+// ==================
+// A similar method is used to generate the T and t values.
+//
+// K * log2_hi + T  must be exact.
+//
+// Smallest T,t
+// ----------
+// The smallest T,t is
+//       T                   t
+// 0x3f60040155d58800, 0x3c93bce0ce3ddd81  log(1/frcpa(1+0/256))=  +1.95503e-003
+//
+// The exponent is 0x3f6 (biased)  or -9 (true).
+// For the smallest T value, what we want is to clip the significand such that
+// when it is shifted right by 9, its lsb is in the bit for 2^-51. The 9 is the
+// specific for the first entry. In general, it is 0xffff - (biased 15-bit
+// exponent).
+
+// Independently, what we have calculated is the table value as a quad
+// precision number.
+// Table entry 1 is
+// 0 fff6 80200aaeac44ef38 338f77605fdf8000
+//
+// We store this quad precision number in a data structure that is
+//    sign:           1
+//    exponent:      15
+//    signficand_hi: 64 (includes explicit bit)
+//    signficand_lo: 49
+// Because the explicit bit is included, the significand is 113 bits.
+//
+// Consider significand_hi for table entry 1.
+//
+//
+// +-+--- ... -------+--------------------+
+// | |
+// +-+--- ... -------+--------------------+
+// 0 1               4444444455555555556666
+//                   2345678901234567890123
+//
+// Labeled as above, bit 0 is 2^0, bit 1 is 2^-1, etc.
+// Bit 42 is 2^-42. If we shift to the right by 9, the bit in
+// bit 42 goes in 51.
+//
+// So what we want to do is shift bits 43 thru 63 into significand_lo.
+// This is shifting bit 42 into bit 63, taking care to retain shifted-off bits.
+// Then shifting (just with signficaand_hi) back into bit 42.
+//
+// The shift_value is 63-42 = 21. In general, this is
+//      63 - (51 -(0xffff - 0xfff6))
+// For this example, it is
+//      63 - (51 - 9) = 63 - 42  = 21
+//
+// This means we are shifting 21 bits into significand_lo. We must maintain more
+// that a 128-bit signficand not to lose bits. So before the shift we put the
+// 128-bit significand into a 256-bit signficand and then shift.
+// The 256-bit significand has four parts: hh, hl, lh, and ll.
+//
+// Start off with
+//      hh         hl         lh         ll
+//      <64>       <49><15_0> <64_0>     <64_0>
+//
+// After shift by 21 (then return for significand_hi),
+//      <43><21_0> <21><43>   <6><58_0>  <64_0>
+//
+// Take the hh part and convert to a double. There is no rounding here.
+// The conversion is exact. The true exponent of the high part is the same as
+// the true exponent of the input quad.
+//
+// We have some 64 plus significand bits for the low part. In this example, we
+// have 70 bits. We want to round this to a double. Put them in a quad and then
+// do a quad fnorm.
+// For this example the true exponent of the low part is
+//      true_exponent_of_high - 43 = true_exponent_of_high - (64-21)
+// In general, this is
+//      true_exponent_of_high - (64 - shift_value)
+//
+//
+// Largest T,t
+// ----------
+// The largest T,t is
+// 0x3fe62643fecf9742, 0x3c9e3147684bd37d  log(1/frcpa(1+255/256))=+6.92171e-001
+//
+// Table entry 256 is
+// 0 fffe b1321ff67cba178c 51da12f4df5a0000
+//
+// The shift value is

+//
+// The true exponent of the low part is

+// History
+//==============================================================
+// 02/02/00 Initial version
+// 02/03/00 Added p12 to definite over/under path. With odd power we did not
+//          maintain the sign of x in this path.
+// 04/04/00 Unwind support added
+// 04/19/00 pow(+-1,inf) now returns NaN
+//          pow(+-val, +-inf) returns 0 or inf, but now does not call error
+//          support
+//          Added s1 to fcvt.fx because invalid flag was incorrectly set.
+// 08/15/00 Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 09/07/00 Improved performance by eliminating bank conflicts and other stalls,
+//          and tweaking the critical path
+// 09/08/00 Per c99, pow(+-1,inf) now returns 1, and pow(+1,nan) returns 1
+// 09/28/00 Updated NaN**0 path
+// 01/20/01 Fixed denormal flag settings.
+// 02/13/01 Improved speed.
+// 03/19/01 Reordered exp polynomial to improve speed and eliminate monotonicity
+//          problem in round up, down, and to zero modes.  Also corrected
+//          overflow result when x negative, y odd in round up, down, zero.
+// 06/14/01 Added brace missing from bundle
+// 12/10/01 Corrected case where x negative, 2^23 <= |y| < 2^24, y odd integer.
+// 02/08/02 Fixed overflow/underflow cases that were not calling error support.
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 08/29/02 Improved Itanium 2 performance
+// 02/10/03 Reordered header: .section, .global, .proc, .align
+// 10/09/03 Modified algorithm to improve performance, reduce table size, and
+//          fix boundary case powf(2.0,-150.0)
+// 03/31/05 Reformatted delimiters between data tables
+//
+// API
+//==============================================================

+//
+// Overview of operation
+//==============================================================
+//
+// Three steps...
+// 1. Log(x)
+// 2. y Log(x)
+// 3. exp(y log(x))
+//
+// This means we work with the absolute value of x and merge in the sign later.
+//      Log(x) = G + delta + r -rsq/2 + p
+// G,delta depend on the exponent of x and table entries. The table entries are
+// indexed by the exponent of x, called K.
+//
+// The G and delta come out of the reduction; r is the reduced x.
+//
+// B = frcpa(x)
+// xB-1 is small means that B is the approximate inverse of x.
+//
+//      Log(x) = Log( (1/B)(Bx) )
+//             = Log(1/B) + Log(Bx)
+//             = Log(1/B) + Log( 1 + (Bx-1))
+//
+//      x  = 2^K 1.x_1x_2.....x_52
+//      B= frcpa(x) = 2^-k Cm
+//      Log(1/B) = Log(1/(2^-K Cm))
+//      Log(1/B) = Log((2^K/ Cm))
+//      Log(1/B) = K Log(2) + Log(1/Cm)
+//
+//      Log(x)   = K Log(2) + Log(1/Cm) + Log( 1 + (Bx-1))
+//
+// If you take the significand of x, set the exponent to true 0, then Cm is
+// the frcpa. We tabulate the Log(1/Cm) values. There are 256 of them.
+// The frcpa table is indexed by 8 bits, the x_1 thru x_8.
+// m = x_1x_2...x_8 is an 8-bit index.
+//
+//      Log(1/Cm) = log(1/frcpa(1+m/256)) where m goes from 0 to 255.
+//
+// We tabluate as one double, T for single precision power
+//
+//      Log(x)   = (K Log(2)_hi + T) + (K Log(2)_lo) + Log( 1 + (Bx-1))
+//      Log(x)   =  G                +     delta     + Log( 1 + (Bx-1))
+//
+// The Log( 1 + (Bx-1)) can be calculated as a series in r = Bx-1.
+//
+//      Log( 1 + (Bx-1)) = r - rsq/2 + p
+//        where p = r^3(P0 + P1*r + P2*r^2)
+//
+// Then,
+//
+//      yLog(x) = yG + y delta + y(r-rsq/2) + yp
+//      yLog(x) = Z1 + e3      + Z2         + Z3
+//
+//
+//     exp(yLog(x)) = exp(Z1 + Z2) exp(Z3) exp(e3)
+//
+//
+//       exp(Z3) is another series.
+//       exp(e3) is approximated as f3 = 1 +  e3
+//
+//       exp(Z1 + Z2) = exp(Z)
+//       Z (128/log2) = number of log2/128 in Z is N
+//
+//       s = Z - N log2/128
+//
+//       exp(Z)       = exp(s) exp(N log2/128)
+//
+//       exp(r)       = exp(Z - N log2/128)
+//
+//      r = s + d = (Z - N (log2/128)_hi) -N (log2/128)_lo
+//                =  Z - N (log2/128)
+//
+//      Z         = s+d +N (log2/128)
+//
+//      exp(Z)    = exp(s) (1+d) exp(N log2/128)
+//
+//      N = M 128 + n
+//
+//      N log2/128 = M log2 + n log2/128
+//
+//      n is 8 binary digits = n_7n_6...n_1
+//
+//      n log2/128 = n_7n_6n_5 16 log2/128 + n_4n_3n_2n_1 log2/128
+//      n log2/128 = n_7n_6n_5 log2/8 + n_4n_3n_2n_1 log2/128
+//      n log2/128 = I2 log2/8 + I1 log2/128
+//
+//      N log2/128 = M log2 + I2 log2/8 + I1 log2/128
+//
+//      exp(Z)    = exp(s) (1+d) exp(log(2^M) + log(2^I2/8) + log(2^I1/128))
+//      exp(Z)    = exp(s) f12 (2^M) 2^I2/8 2^I1/128
+//
+// I1, I2 are table indices. Use a series for exp(s).
+// Then get exp(Z)
+//
+//     exp(yLog(x)) = exp(Z) exp(Z3) f3
+//     exp(yLog(x)) = exp(Z)f3 exp(Z3)
+//     exp(yLog(x)) = A exp(Z3)
+//
+// We actually calculate exp(Z3) -1.
+// Then,
+//     exp(yLog(x)) = A + A( exp(Z3)   -1)
+//
+
+// Table Generation
+//==============================================================
+
+// The log values
+// ==============
+// The operation (K*log2_hi) must be exact. K is the true exponent of x.
+// If we allow gradual underflow (denormals), K can be represented in 12 bits
+// (as a two's complement number). We assume 13 bits as an engineering
+// precaution.
+//
+//           +------------+----------------+-+
+//           |  13 bits   | 50 bits        | |
+//           +------------+----------------+-+
+//           0            1                66
+//                        2                34
+//
+// So we want the lsb(log2_hi) to be 2^-50
+// We get log2 as a quad-extended (15-bit exponent, 128-bit significand)
+//
+//      0 fffe b17217f7d1cf79ab c9e3b39803f2f6af (4...)
+//
+// Consider numbering the bits left to right, starting at 0 thru 127.
+// Bit 0 is the 2^-1 bit; bit 49 is the 2^-50 bit.
+//
+//  ...79ab
+//     0111 1001 1010 1011
+//     44
+//     89
+//
+// So if we shift off the rightmost 14 bits, then (shift back only
+// the top half) we get
+//
+//      0 fffe b17217f7d1cf4000 e6af278ece600fcb dabc000000000000
+//
+// Put the right 64-bit signficand in an FR register, convert to double;
+// it is exact. Put the next 128 bits into a quad register and round to double.
+// The true exponent of the low part is -51.
+//
+// hi is 0 fffe b17217f7d1cf4000
+// lo is 0 ffcc e6af278ece601000
+//
+// Convert to double memory format and get
+//
+// hi is 0x3fe62e42fefa39e8
+// lo is 0x3cccd5e4f1d9cc02
+//
+// log2_hi + log2_lo is an accurate value for log2.
+//
+//
+// The T and t values
+// ==================
+// A similar method is used to generate the T and t values.
+//
+// K * log2_hi + T  must be exact.
+//
+// Smallest T,t
+// ----------
+// The smallest T,t is
+//       T                   t
+// 0x3f60040155d58800, 0x3c93bce0ce3ddd81  log(1/frcpa(1+0/256))=  +1.95503e-003
+//
+// The exponent is 0x3f6 (biased)  or -9 (true).
+// For the smallest T value, what we want is to clip the significand such that
+// when it is shifted right by 9, its lsb is in the bit for 2^-51. The 9 is the
+// specific for the first entry. In general, it is 0xffff - (biased 15-bit
+// exponent).
+
+// Independently, what we have calculated is the table value as a quad
+// precision number.
+// Table entry 1 is
+// 0 fff6 80200aaeac44ef38 338f77605fdf8000
+//
+// We store this quad precision number in a data structure that is
+//    sign:           1
+//    exponent:      15
+//    signficand_hi: 64 (includes explicit bit)
+//    signficand_lo: 49
+// Because the explicit bit is included, the significand is 113 bits.
+//
+// Consider significand_hi for table entry 1.
+//
+//
+// +-+--- ... -------+--------------------+
+// | |
+// +-+--- ... -------+--------------------+
+// 0 1               4444444455555555556666
+//                   2345678901234567890123
+//
+// Labeled as above, bit 0 is 2^0, bit 1 is 2^-1, etc.
+// Bit 42 is 2^-42. If we shift to the right by 9, the bit in
+// bit 42 goes in 51.
+//
+// So what we want to do is shift bits 43 thru 63 into significand_lo.
+// This is shifting bit 42 into bit 63, taking care to retain shifted-off bits.
+// Then shifting (just with signficaand_hi) back into bit 42.
+//
+// The shift_value is 63-42 = 21. In general, this is
+//      63 - (51 -(0xffff - 0xfff6))
+// For this example, it is
+//      63 - (51 - 9) = 63 - 42  = 21
+//
+// This means we are shifting 21 bits into significand_lo. We must maintain more
+// that a 128-bit signficand not to lose bits. So before the shift we put the
+// 128-bit significand into a 256-bit signficand and then shift.
+// The 256-bit significand has four parts: hh, hl, lh, and ll.
+//
+// Start off with
+//      hh         hl         lh         ll
+//      <64>       <49><15_0> <64_0>     <64_0>
+//
+// After shift by 21 (then return for significand_hi),
+//      <43><21_0> <21><43>   <6><58_0>  <64_0>
+//
+// Take the hh part and convert to a double. There is no rounding here.
+// The conversion is exact. The true exponent of the high part is the same as
+// the true exponent of the input quad.
+//
+// We have some 64 plus significand bits for the low part. In this example, we
+// have 70 bits. We want to round this to a double. Put them in a quad and then
+// do a quad fnorm.
+// For this example the true exponent of the low part is
+//      true_exponent_of_high - 43 = true_exponent_of_high - (64-21)
+// In general, this is
+//      true_exponent_of_high - (64 - shift_value)
+//
+//
+// Largest T,t
+// ----------
+// The largest T,t is
+// 0x3fe62643fecf9742, 0x3c9e3147684bd37d  log(1/frcpa(1+255/256))=+6.92171e-001
+//
+// Table entry 256 is
+// 0 fffe b1321ff67cba178c 51da12f4df5a0000
+//
+// The shift value is
+//      63 - (51 -(0xffff - 0xfffe)) = 13
+//
+// The true exponent of the low part is
+//      true_exponent_of_high - (64 - shift_value)
+//      -1 - (64-13) = -52
+// Biased as a double, this is 0x3cb

+// History
+//====================================================================
+// 02/02/00 Initial version
+// 03/02/00 New Algorithm
+// 04/04/00 Unwind support added
+// 07/21/00 Fixed quotient=2^{24*m+23}*1.q1...q23 1 bug
+// 08/15/00 Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 11/29/00 Set FR_Y to f9
+// 05/20/02 Cleaned up namespace and sf0 syntax

+// double remainder(double,double);
+//
+// Overview of operation
+//====================================================================
+//  remainder(a,b)=a-i*b,
+//  where i is an integer such that, if b!=0 and a is finite,
+//  |a/b-i|<=1/2. If |a/b-i|=1/2, i is even.
+//
+// Algorithm
+//====================================================================
+// a). eliminate special cases
+// b). if |a/b|<0.25 (first quotient estimate), return a
+// c). use single precision divide algorithm to get quotient q
+//     rounded to 24 bits of precision
+// d). calculate partial remainders (using both q and q-ulp);
+//     select one and RZ(a/b) based on the sign of |a|-|b|*q
+// e). if the exponent difference (exponent(a)-exponent(b))
+//     is less than 24 (quotient estimate<2^{24}-2), use RZ(a/b)
+//     and sticky bits to round to integer; exit loop and
+//     calculate final remainder
+// f). if exponent(a)-exponent(b)>=24, select new value of a as
+//     the partial remainder calculated using RZ(a/b);
+//     repeat from c).
+//
+// Special cases
+//====================================================================
+// a=+/- Inf, or b=+/-0: return NaN, call libm_error_support
+// a=NaN or b=NaN: return NaN

+// float remainderf(float,float);
+//
+// Overview of operation
+//====================================================================
+//  remainder(a,b)=a-i*b,
+//  where i is an integer such that, if b!=0 and a is finite,
+//  |a/b-i|<=1/2. If |a/b-i|=1/2, i is even.
+//
+// Algorithm
+//====================================================================
+// a). eliminate special cases
+// b). if |a/b|<0.25 (first quotient estimate), return a
+// c). use single precision divide algorithm to get quotient q
+//     rounded to 24 bits of precision
+// d). calculate partial remainders (using both q and q-ulp);
+//     select one and RZ(a/b) based on the sign of |a|-|b|*q
+// e). if the exponent difference (exponent(a)-exponent(b))
+//     is less than 24 (quotient estimate<2^{24}-2), use RZ(a/b)
+//     and sticky bits to round to integer; exit loop and
+//     calculate final remainder
+// f). if exponent(a)-exponent(b)>=24, select new value of a as
+//     the partial remainder calculated using RZ(a/b);
+//     repeat from c).
+//
+// Special cases
+//====================================================================
+// a=+/- Inf, or b=+/-0: return NaN, call libm_error_support
+// a=NaN or b=NaN: return NaN
+//
+// Registers used

+// long double remainderl(long double,long double);
+//
+// Overview of operation
+//====================================================================
+//  remainder(a,b)=a-i*b,
+//  where i is an integer such that, if b!=0 and a is finite,
+//  |a/b-i|<=1/2. If |a/b-i|=1/2, i is even.
+//
+// Algorithm
+//====================================================================
+// a). eliminate special cases
+// b). if |a/b|<0.25 (first quotient estimate), return a
+// c). use single precision divide algorithm to get quotient q
+//     rounded to 24 bits of precision
+// d). calculate partial remainders (using both q and q-ulp);
+//     select one and RZ(a/b) based on the sign of |a|-|b|*q
+// e). if the exponent difference (exponent(a)-exponent(b))
+//     is less than 24 (quotient estimate<2^{24}-2), use RZ(a/b)
+//     and sticky bits to round to integer; exit loop and
+//     calculate final remainder
+// f). if exponent(a)-exponent(b)>=24, select new value of a as
+//     the partial remainder calculated using RZ(a/b);
+//     repeat from c).
+//
+// Special cases
+//====================================================================
+// a=+/- Inf, or b=+/-0: return NaN, call libm_error_support
+// a=NaN or b=NaN: return NaN
+//
+// Registers used

+// API
+//==============================================================

+
+// Overview of operation
+//==============================================================
+// Case 1:  0 < |x| < 2^-60
+//  Result = x, computed by x+sgn(x)*x^2) to handle flags and rounding
+//
+// Case 2:  2^-60 < |x| < 0.25
+//  Evaluate sinh(x) by a 13th order polynomial
+//  Care is take for the order of multiplication; and A1 is not exactly 1/3!,
+//  A2 is not exactly 1/5!, etc.
+//  sinh(x) = x + (A1*x^3 + A2*x^5 + A3*x^7 + A4*x^9 + A5*x^11 + A6*x^13)
+//
+// Case 3:  0.25 < |x| < 710.47586
+//  Algorithm is based on the identity sinh(x) = ( exp(x) - exp(-x) ) / 2.
+//  The algorithm for exp is described as below.  There are a number of
+//  economies from evaluating both exp(x) and exp(-x).  Although we
+//  are evaluating both quantities, only where the quantities diverge do we
+//  duplicate the computations.  The basic algorithm for exp(x) is described
+//  below.
+//
+// Take the input x. w is "how many log2/128 in x?"
+//  w = x * 128/log2
+//  n = int(w)
+//  x = n log2/128 + r + delta
+
+//  n = 128M + index_1 + 2^4 index_2
+//  x = M log2 + (log2/128) index_1 + (log2/8) index_2 + r + delta
+
+//  exp(x) = 2^M  2^(index_1/128)  2^(index_2/8) exp(r) exp(delta)
+//       Construct 2^M
+//       Get 2^(index_1/128) from table_1;
+//       Get 2^(index_2/8)   from table_2;
+//       Calculate exp(r) by 5th order polynomial
+//          r = x - n (log2/128)_high
+//          delta = - n (log2/128)_low
+//       Calculate exp(delta) as 1 + delta
+
+
+// Special values
+//==============================================================
+// sinh(+0)    = +0
+// sinh(-0)    = -0
+
+// sinh(+qnan) = +qnan
+// sinh(-qnan) = -qnan
+// sinh(+snan) = +qnan
+// sinh(-snan) = -qnan
+
+// sinh(-inf)  = -inf

+
+// Overflow and Underflow

+// Overview of operation
+//*********************************************************************
+// Case 1:  0 < |x| < 2^-60
+//  Result = x, computed by x+sgn(x)*x^2) to handle flags and rounding
+//
+// Case 2:  2^-60 < |x| < 0.25
+//  Evaluate sinh(x) by a 9th order polynomial
+//  Care is take for the order of multiplication; and A2 is not exactly 1/5!,
+//  A3 is not exactly 1/7!, etc.
+//  sinh(x) = x + (A1*x^3 + A2*x^5 + A3*x^7 + A4*x^9)
+//
+// Case 3:  0.25 < |x| < 89.41598
+//  Algorithm is based on the identity sinh(x) = ( exp(x) - exp(-x) ) / 2.
+//  The algorithm for exp is described as below.  There are a number of
+//  economies from evaluating both exp(x) and exp(-x).  Although we
+//  are evaluating both quantities, only where the quantities diverge do we
+//  duplicate the computations.  The basic algorithm for exp(x) is described
+//  below.
+//
+// Take the input x. w is "how many log2/128 in x?"
+//  w = x * 64/log2
+//  NJ = int(w)
+//  x = NJ*log2/64 + R
+
+//  NJ = 64*n + j
+//  x = n*log2 + (log2/64)*j + R
+//
+//  So, exp(x) = 2^n * 2^(j/64)* exp(R)
+//
+//  T =  2^n * 2^(j/64)
+//       Construct 2^n
+//       Get 2^(j/64) table
+//           actually all the entries of 2^(j/64) table are stored in DP and
+//           with exponent bits set to 0 -> multiplication on 2^n can be
+//           performed by doing logical "or" operation with bits presenting 2^n
+
+//  exp(R) = 1 + (exp(R) - 1)
+//  P = exp(R) - 1 approximated by Taylor series of 3rd degree
+//      P = A3*R^3 + A2*R^2 + R, A3 = 1/6, A2 = 1/2
+//
+
+//  The final result is reconstructed as follows
+//  exp(x) = T + T*P

+// 1. SINH_BY_POLY   0 < |x| < 0.25
+// ===============
+// Evaluate sinh(x) by a 13th order polynomial
+// Care is take for the order of multiplication; and P_1 is not exactly 1/3!,
+// P_2 is not exactly 1/5!, etc.
+// sinh(x) = sign * (series(e^x) - series(e^-x))/2
+//         = sign * (ax + ax^3/3! + ax^5/5! + ax^7/7! + ax^9/9! + ax^11/11!

+//         = sign * (ax   + Y_lo)
+// sinh(x) = sign * (Y_hi + Y_lo)
+// Note that ax = |x|
+//
+// 2. SINH_BY_TBL   0.25 <= |x| < 32.0
+// =============
+// sinh(x) = sinh(B+R)
+//         = sinh(B)cosh(R) + cosh(B)sinh(R)
+//
+// ax = |x| = M*log2/64 + R
+// B = M*log2/64
+// M = 64*N + j
+//   We will calculate M and get N as (M-j)/64
+//   The division is a shift.
+// exp(B)  = exp(N*log2 + j*log2/64)
+//         = 2^N * 2^(j*log2/64)
+// sinh(B) = 1/2(e^B -e^-B)
+//         = 1/2(2^N * 2^(j*log2/64) - 2^-N * 2^(-j*log2/64))
+// sinh(B) = (2^(N-1) * 2^(j*log2/64) - 2^(-N-1) * 2^(-j*log2/64))
+// cosh(B) = (2^(N-1) * 2^(j*log2/64) + 2^(-N-1) * 2^(-j*log2/64))
+// 2^(j*log2/64) is stored as Tjhi + Tjlo , j= -32,....,32
+// Tjhi is double-extended (80-bit) and Tjlo is single(32-bit)
+//
+// R = ax - M*log2/64
+// R = ax - M*log2_by_64_hi - M*log2_by_64_lo
+// exp(R) = 1 + R +R^2(1/2! + R(1/3! + R(1/4! + ... + R(1/n!)...)
+//        = 1 + p_odd + p_even
+//        where the p_even uses the A coefficients and the p_even uses
+//        the B coefficients
+//
+// So sinh(R) = 1 + p_odd + p_even -(1 -p_odd -p_even)/2 = p_odd
+//    cosh(R) = 1 + p_even
+//    sinh(B) = S_hi + S_lo
+//    cosh(B) = C_hi
+// sinh(x) = sinh(B)cosh(R) + cosh(B)sinh(R)
+//
+// 3. SINH_BY_EXP   32.0 <= |x| < 11357.21655  ( 400c b174 ddc0 31ae c0ea )
+// ==============
+// Can approximate result by exp(x)/2 in this region.
+// Y_hi = Tjhi
+// Y_lo = Tjhi * (p_odd + p_even) + Tjlo
+// sinh(x) = Y_hi + Y_lo

+// 4. SINH_HUGE     |x| >= 11357.21655  ( 400c b174 ddc0 31ae c0ea )

+// Overview
+//
+// The method consists of three cases.
+//
+// If      512 <= x < OVERFLOW_BOUNDARY   use case lgamma_pstirling;
+// else if 1 < x < 512                    use case lgamma_regular;
+// else if -17 < x < 1                    use case lgamma_negrecursion;
+// else if -512 <  x < -17                use case lgamma_negpoly;
+// else if x < -512                       use case lgamma_negstirling;
+// else if x is close to negative
+//         roots of ln(GAMMA(x))          use case lgamma_negroots;
+//
+//
+// Case 512 <= x < OVERFLOW_BOUNDARY
+// ---------------------------------
+//   Here we use algorithm based on the Stirling formula:
+//   ln(GAMMA(x)) = ln(sqrt(2*Pi)) + (x-0.5)ln(x) - x + (W2 + W4/x^2)/x
+//
+// Case 1 < x < 512
+// ----------------
+//   To calculate GAMMA(x) on this interval we use polynomial approximation
+//   on following intervals [0.875; 1.25), [1.25; 1.75), [1.75, 2.25),
+//   [2.25; 4), [2^i; 2^(i+1)), i=2..8
+//
+//   Following variants of approximation and argument reduction are used:
+//    1. [0.875; 1.25)
+//       ln(GAMMA(x)) ~ (x-1.0)*P17(x-1.0)
+//
+//    2. [1.25; 1.75)
+//       ln(GAMMA(x)) ~ (x-LocalMinimun)*P17(x-LocalMinimun)
+//
+//    3. [1.75, 2.25)
+//       ln(GAMMA(x)) ~ (x-2.0)*P17(x-2.0)
+//
+//    4. [2.25; 4)
+//       ln(GAMMA(x)) ~ P22(x)
+//
+//    5. [2^i; 2^(i+1)), i=2..8
+//       ln(GAMMA(x)) ~ P22((x-2^i)/2^i)
+//
+// Case -17 < x < 1
+// ----------------
+//   Here we use the recursive formula:
+//   ln(GAMMA(x)) = ln(GAMMA(x+1)) - ln(x)
+//
+//   Using this formula we reduce argument to base interval [1.0; 2.0]
+//
+// Case -512 <  x < -17
+// --------------------
+//   Here we use the formula:
+//   ln(GAMMA(-x)) = ln(Pi/(x*GAMMA(x)*sin(Pi*x))) =
+//   = -ln(x) - ln((GAMMA(x)) - ln(sin(Pi*r)/(Pi*r)) - ln(|r|)
+//   where r = x - rounded_to_nearest(x), i.e |r| <= 0.5 and
+//   ln(sin(Pi*r)/(Pi*r)) is approximated by 14-degree polynomial of r^2
+//
+//
+// Case x < -512
+// -------------
+//   Here we use algorithm based on the Stirling formula:
+//   ln(GAMMA(-x)) = -ln(sqrt(2*Pi)) + (-x-0.5)ln(x) + x - (W2 + W4/x^2)/x -
+//   - ln(sin(Pi*r)/(Pi*r)) - ln(|r|)
+//   where r = x - rounded_to_nearest(x).
+//
+// Neighbourhoods of negative roots
+// --------------------------------
+//   Here we use polynomial approximation
+//   ln(GAMMA(x-x0)) = ln(GAMMA(x0)) + (x-x0)*P14(x-x0),
+//   where x0 is a root of ln(GAMMA(x)) rounded to nearest double
+//   precision number.

+// Overview
+//
+// The method consists of three cases.
+//
+// If      2^13 <= x < OVERFLOW_BOUNDARY  use case lgammaf_pstirling;
+// else if 1 < x < 2^13                   use case lgammaf_regular;
+// else if -9 < x < 1                     use case lgammaf_negrecursion;
+// else if -2^13 <  x < -9                use case lgammaf_negpoly;
+// else if x < -2^13                      use case lgammaf_negstirling;
+// else if x is close to negative
+//         roots of ln(GAMMA(x))          use case lgammaf_negroots;
+//
+//
+// Case 2^13 <= x < OVERFLOW_BOUNDARY
+// ----------------------------------
+//   Here we use algorithm based on the Stirling formula:
+//     ln(GAMMA(x)) = ln(sqrt(2*Pi)) + (x-0.5)*ln(x) - x
+//
+// Case 1 < x < 2^13
+// -----------------
+//   To calculate ln(GAMMA(x)) for such arguments we use polynomial
+//   approximation on following intervals: [1.0; 1.25), [1.25; 1.5),
+//   [1.5, 1.75), [1.75; 2), [2; 4), [2^i; 2^(i+1)), i=1..8
+//
+//   Following variants of approximation and argument reduction are used:
+//    1. [1.0; 1.25)
+//       ln(GAMMA(x)) ~ (x-1.0)*P7(x)
+//
+//    2. [1.25; 1.5)
+//       ln(GAMMA(x)) ~ ln(GAMMA(x0))+(x-x0)*P8(x-x0),
+//       where x0 - point of local minimum on [1;2] rounded to nearest double
+//       precision number.
+//
+//    3. [1.5; 1.75)
+//       ln(GAMMA(x)) ~ P8(x)
+//
+//    4. [1.75; 2.0)
+//       ln(GAMMA(x)) ~ (x-2)*P7(x)
+//
+//    5. [2; 4)
+//       ln(GAMMA(x)) ~ (x-2)*P10(x)
+//
+//    6. [2^i; 2^(i+1)), i=2..8
+//       ln(GAMMA(x)) ~ P10((x-2^i)/2^i)
+//
+// Case -9 < x < 1
+// ---------------
+//   Here we use the recursive formula:
+//   ln(GAMMA(x)) = ln(GAMMA(x+1)) - ln(x)
+//
+//   Using this formula we reduce argument to base interval [1.0; 2.0]
+//
+// Case -2^13 < x < -9
+// --------------------
+//   Here we use the formula:
+//   ln(GAMMA(x)) = ln(Pi/(|x|*GAMMA(|x|)*sin(Pi*|x|))) =
+//   = -ln(|x|) - ln((GAMMA(|x|)) - ln(sin(Pi*r)/(Pi*r)) - ln(|r|)
+//   where r = x - rounded_to_nearest(x), i.e |r| <= 0.5 and
+//   ln(sin(Pi*r)/(Pi*r)) is approximated by 8-degree polynomial of r^2
+//
+// Case x < -2^13
+// --------------
+//   Here we use algorithm based on the Stirling formula:
+//   ln(GAMMA(x)) = -ln(sqrt(2*Pi)) + (|x|-0.5)ln(x) - |x| -
+//   - ln(sin(Pi*r)/(Pi*r)) - ln(|r|)
+//   where r = x - rounded_to_nearest(x).
+//
+// Neighbourhoods of negative roots
+// --------------------------------
+//   Here we use polynomial approximation
+//   ln(GAMMA(x-x0)) = ln(GAMMA(x0)) + (x-x0)*P14(x-x0),
+//   where x0 is a root of ln(GAMMA(x)) rounded to nearest double
+//   precision number.
+//
+//
+// Claculation of logarithm
+// ------------------------
+//   Consider  x = 2^N * xf so
+//   ln(x) = ln(frcpa(x)*x/frcpa(x))
+//         = ln(1/frcpa(x)) + ln(frcpa(x)*x)
+//
+//   frcpa(x) = 2^(-N) * frcpa(xf)
+//
+//   ln(1/frcpa(x)) = -ln(2^(-N)) - ln(frcpa(xf))
+//                  = N*ln(2) - ln(frcpa(xf))
+//                  = N*ln(2) + ln(1/frcpa(xf))
+//
+//   ln(x) = ln(1/frcpa(x)) + ln(frcpa(x)*x) =
+//         = N*ln(2) + ln(1/frcpa(xf)) + ln(frcpa(x)*x)
+//         = N*ln(2) + T + ln(frcpa(x)*x)
+//
+//   Let r = 1 - frcpa(x)*x, note that r is quite small by
+//   absolute value so
+//
+//   ln(x) = N*ln(2) + T + ln(1+r) ~ N*ln(2) + T + Series(r),
+//   where T - is precomputed tabular value,
+//   Series(r) = (P3*r + P2)*r^2 + (P1*r + 1)

+// ALGORITHM DESCRIPTION
+//
+// Below we suppose that there is log(z) function which takes an long
+// double argument and returns result as a pair of long double numbers
+// lnHi and lnLo (such that sum lnHi + lnLo provides ~80 correct bits
+// of significand). Algorithm description for such log(z) function
+// see below.
+// Also, it this algorithm description we use the following notational
+// conventions:
+// a) pair A = (Ahi, Alo) means number A represented as sum of Ahi and Alo
+// b) C = A + B = (Ahi, Alo) + (Bhi, Blo) means multi-precision addition.
+//    The result would be C = (Chi, Clo). Notice, that Clo shouldn't be
+//    equal to Alo + Blo
+// c) D = A*B = (Ahi, Alo)*(Bhi, Blo) = (Dhi, Dlo) multi-precisiion
+//    multiplication.
+//
+// So, lgammal has the following computational paths:
+// 1) |x| < 0.5
+//    P = A1*|x| + A2*|x|^2 + ... + A22*|x|^22
+//    A1, A2, A3 represented as a sum of two double precision
+//    numbers and multi-precision computations are used for 3 higher
+//    terms of the polynomial. We get polynomial as a sum of two
+//    double extended numbers: P = (Phi, Plo)
+//    1.1) x > 0
+//         lgammal(x) = P - log(|x|) = (Phi, Plo) - (lnHi(|x|), lnLo(|x|))
+//    1.2) x < 0
+//         lgammal(x) = -P - log(|x|) - log(sin(Pi*x)/(Pi*x))
+//         P and log(|x|) are computed by the same way as in 1.1;
+//         - log(sin(Pi*x)/(Pi*x)) is approximated by a polynomial Plnsin.
+//         Plnsin:= fLnSin2*|x|^2 + fLnSin4*|x|^4 + ... + fLnSin36*|x|^36
+//         The first coefficient of Plnsin is represented as sum of two
+//         double precision numbers (fLnSin2, fLnSin2L). Multi-precision
+//         computations for higher two terms of Plnsin are used.
+//         So, the final result is reconstructed by the following formula
+//         lgammal(x) = (-(Phi, Plo) - (lnHi(|x|), lnLo(|x|))) -
+//                      - (PlnsinHi,PlnsinLo)
+//

+//                                   approximate value is ~1.46
+//
+//    lgammal(x) is approximated by the polynomial of 25th degree: P25(t)
+//    P25(t) = A0 + A1*t + ... + A25*t^25 = (Phi, Plo) + t^4*P21(t),

+//    (Phi, Plo) = ((A0, A0L) + (A1, A1L)*t) + t^2 *((A2, A2L) + (A3, A3L)*t),
+//    (Ai, AiL) - coefficients represented as pairs of DP numbers.
+//
+//    P21(t) = (PolC(t)*t^8 + PolD(t))*t^8 + PolE(t),
+//    where
+//    PolC(t) = C21*t^5 + C20*t^4 + ... + C16,
+//    C21 = A25, C20 = A24, ..., C16 = A20

+//
+// 4) 10.0 < x <= Overflow Bound ("positive Sterling" range)
+//    lgammal(x) is approximated using Sterling's formula:
+//    lgammal(x) ~ ((x*(lnHi(x) - 1, lnLo(x))) - 0.5*(lnHi(x), lnLo(x))) +
+//                 + ((Chi, Clo) + S(1/x))
+//    where
+//    C = (Chi, Clo) - pair of double precision numbers representing constant
+//    0.5*ln(2*Pi);
+//    S(1/x) = 1/x * (B2 + B4*(1/x)^2 + ... + B20*(1/x)^18), B2, ..., B20 are
+//    Bernulli numbers. S is computed in native precision and then added to
+//    Clo;
+//    lnHi(x) - 1 is computed in native precision and the multiprecision
+//    multiplication (x, 0) *(lnHi(x) - 1, lnLo(x)) is used.
+//
+// 5) -INF < x <= -2^63, any negative integer < 0
+//    All numbers in this range are integers -> error handler is called
+//
+// 6) -2^63 < x <= -0.75 ("negative Sterling" range), x is "far" from root,
+//    lgammal(-t) for positive t is approximated using the following formula:
+//    lgammal(-t) = -lgammal(t)-log(t)-log(|dT|)+log(sin(Pi*|dT|)/(Pi*|dT|))
+//        where dT = -t -round_to_nearest_integer(-t)
+//    Last item is approximated by the same polynomial as described in 1.2.
+//    We split the whole range into three subranges due to different ways of
+//    approximation of the first terms.
+//    6.1) -2^63 < x < -6.0 ("negative Sterling" range)
+//       lgammal(t) is approximated exactly as in #4. The only difference that
+//       for -13.0 < x < -6.0 subrange instead of Bernulli numbers we use their
+//       minimax approximation on this range.
+//       log(t), log(|dT|) are approximated by the log routine mentioned above.
+//    6.2) -6.0 < x <= -0.75, |x + 1|> 2^(-7)
+//       log(t), log(|dT|) are approximated by the log routine mentioned above,
+//       lgammal(t) is approximated by polynomials of the 25th degree similar
+//       to ones from #2. Arguments z of the polynomials are as follows
+//       a) 0.75 <= t < 1.0 - 2^(-7),  z = 2*t - 1.5
+//       b) 1.0 - 2^(-7)  < t < 2.0,   z = t - 1.5
+//       c) 2.0  < t < 3.0,   z = t/2 - 1.5
+//       d) 3.0  < t < 4.0,   z = t/2 - 1.5. Notice, that range reduction is
+//          the same as in case c) but the set of coefficients is different
+//       e) 4.0  < t < 6.0,   z = t/4 - 1.5
+//    6.3) |x + 1| <= 2^(-7)
+//       log(1 + (x-1)) is approximated by Taylor series,
+//       log(sin(Pi*|dT|)/(Pi*|dT|)) is still approximated by polynomial but
+//       it has just 4th degree.
+//       log(|dT|) is approximated by the log routine mentioned above.
+//       lgammal(-x) is approximated by polynomial of 8th degree from (-x + 1).
+//
+// 7) -20.0 < x < -2.0, x falls in root "neighbourhood".
+//    "Neighbourhood" means that |lgammal(x)| < epsilon, where epsilon is
+//    different for every root (and it is stored in the table), but typically
+//    it is ~ 0.15. There are 35 roots significant from "double extended"
+//    point of view. We split all the roots into two subsets: "left" and "right"
+//    roots. Considering [-(N+1), -N] range we call root as "left" one if it
+//    lies closer to -(N+1) and "right" otherwise. There is no "left" root in
+//    the [-20, -19] range (it exists, but is insignificant for double extended
+//    precision). To determine if x falls in root "neighbourhood" we store
+//    significands of all the 35 roots as well as epsilon values (expressed
+//    by the left and right bound).
+//    In these ranges we approximate lgammal(x) by polynomial series of 19th
+//    degree:
+//    lgammal(x) = P19(t) = A0 + A1*t + ...+ A19*t^19, where t = x - EDP_Root,
+//    EDP_Root is the exact value of the corresponding root rounded to double
+//    extended precision. So, we have 35 different polynomials which make our
+//    table rather big. We may hope that x falls in root "neighbourhood"
+//    quite rarely -> ther might be no need in frequent use of different
+//    polynomials.
+//    A0, A1, A2, A3 are represented as pairs of double precision numbers,
+//    A4, A5 are long doubles, and to decrease the size of the table we
+//    keep the rest of coefficients in just double precision
+//
+//*********************************************************************
+// Algorithm for log(X) = (lnHi(X), lnLo(X))
+//
+//   ALGORITHM
+//
+//   Here we use a table lookup method. The basic idea is that in
+//   order to compute logl(Arg) for an argument Arg in [1,2), we
+//   construct a value G such that G*Arg is close to 1 and that
+//   logl(1/G) is obtainable easily from a table of values calculated
+//   beforehand. Thus
+//
+//      logl(Arg) = logl(1/G) + logl(G*Arg)
+//                = logl(1/G) + logl(1 + (G*Arg - 1))
+//
+//   Because |G*Arg - 1| is small, the second term on the right hand
+//   side can be approximated by a short polynomial. We elaborate
+//   this method in four steps.
+//
+//   Step 0: Initialization
+//
+//   We need to calculate logl( X ). Obtain N, S_hi such that
+//
+//      X = 2^N * S_hi exactly
+//
+//   where S_hi in [1,2)
+//
+//   Step 1: Argument Reduction
+//
+//   Based on S_hi, obtain G_1, G_2, G_3 from a table and calculate
+//
+//      G := G_1 * G_2 * G_3
+//      r := (G * S_hi - 1)
+//
+//   These G_j's have the property that the product is exactly
+//   representable and that |r| < 2^(-12) as a result.
+//
+//   Step 2: Approximation
+//
+//
+//   logl(1 + r) is approximated by a short polynomial poly(r).
+//
+//   Step 3: Reconstruction
+//
+//
+//   Finally, logl( X ) is given by
+//
+//   logl( X )   =   logl( 2^N * S_hi )
+//                 ~=~  N*logl(2) + logl(1/G) + logl(1 + r)
+//                 ~=~  N*logl(2) + logl(1/G) + poly(r).
+//
+//   IMPLEMENTATION
+//
+//   Step 0. Initialization
+//   ----------------------
+//
+//   Z := X
+//   N := unbaised exponent of Z
+//   S_hi := 2^(-N) * Z
+//
+//   Step 1. Argument Reduction
+//   --------------------------
+//
+//   Let
+//
+//      Z = 2^N * S_hi = 2^N * 1.d_1 d_2 d_3 ... d_63
+//
+//   We obtain G_1, G_2, G_3 by the following steps.
+//
+//
+//      Define          X_0 := 1.d_1 d_2 ... d_14. This is extracted
+//                      from S_hi.
+//
+//      Define          A_1 := 1.d_1 d_2 d_3 d_4. This is X_0 truncated
+//                      to lsb = 2^(-4).
+//
+//      Define          index_1 := [ d_1 d_2 d_3 d_4 ].
+//
+//      Fetch           Z_1 := (1/A_1) rounded UP in fixed point with
+//      fixed point     lsb = 2^(-15).
+//                      Z_1 looks like z_0.z_1 z_2 ... z_15
+//                      Note that the fetching is done using index_1.
+//                      A_1 is actually not needed in the implementation
+//                      and is used here only to explain how is the value
+//                      Z_1 defined.
+//
+//      Fetch           G_1 := (1/A_1) truncated to 21 sig. bits.
+//      floating pt.    Again, fetching is done using index_1. A_1
+//                      explains how G_1 is defined.
+//
+//      Calculate       X_1 := X_0 * Z_1 truncated to lsb = 2^(-14)
+//                           = 1.0 0 0 0 d_5 ... d_14

+//                      This is 2^(-14) + X_2 truncated to lsb = 2^(-13).

+//
+//
+//  Step 2. Approximation
+//  ---------------------
+//
+//   This step computes an approximation to logl( 1 + r ) where r is the
+//   reduced argument just obtained. It is proved that |r| <= 1.9*2^(-13);
+//   thus logl(1+r) can be approximated by a short polynomial:
+//
+//      logl(1+r) ~=~ poly = r + Q1 r^2 + ... + Q4 r^5
+//
+//
+//  Step 3. Reconstruction
+//  ----------------------
+//
+//   This step computes the desired result of logl(X):
+//
+//      logl(X)  =   logl( 2^N * S_hi )
+//               =   N*logl(2) + logl( S_hi )
+//               =   N*logl(2) + logl(1/G) +
+//                      logl(1 + G*S_hi - 1 )
+//
+//   logl(2), logl(1/G_j) are stored as pairs of (single,double) numbers:
+//   log2_hi, log2_lo, log1byGj_hi, log1byGj_lo. The high parts are
+//   single-precision numbers and the low parts are double precision
+//   numbers. These have the property that
+//
+//      N*log2_hi + SUM ( log1byGj_hi )
+//
+//   is computable exactly in double-extended precision (64 sig. bits).
+//   Finally
+//
+//      lnHi(X) := N*log2_hi + SUM ( log1byGj_hi )
+//      lnLo(X) := poly_hi + [ poly_lo +
+//              ( SUM ( log1byGj_lo ) + N*log2_lo ) ]

+// I. Introduction
+// ===============
+//
+// For the forward trigonometric functions sin, cos, sincos, and
+// tan, the original algorithms for IA 64 handle arguments up to
+// 1 ulp less than 2^63 in magnitude. For double-extended arguments x,
+// |x| >= 2^63, this routine returns N and r_hi, r_lo where
+//
+//    x  is accurately approximated by
+//    2*K*pi  +  N * pi/2  +  r_hi + r_lo,  |r_hi+r_lo| <= pi/4.
+//    CASE = 1 or 2.
+//    CASE is 1 unless |r_hi + r_lo| < 2^(-33).
+//
+// The exact value of K is not determined, but that information is
+// not required in trigonometric function computations.
+//
+// We first assume the argument x in question satisfies x >= 2^(63).
+// In particular, it is positive. Negative x can be handled by symmetry:
+//
+//   -x  is accurately approximated by
+//         -2*K*pi  +  (-N) * pi/2  -  (r_hi + r_lo),  |r_hi+r_lo| <= pi/4.
+//
+// The idea of the reduction is that
+//
+//       x  *  2/pi   =   N_big  +  N  +  f,      |f| <= 1/2
+//
+// Moreover, for double extended x, |f| >= 2^(-75). (This is an
+// non-obvious fact found by enumeration using a special algorithm
+// involving continued fraction.) The algorithm described below

+//
+// III. Algorithm
+// ==============
+//
+// This describes the algorithm in the most natural way using
+// unsigned interger multiplication. The implementation section
+// describes how the integer arithmetic is simulated.
+//
+// STEP 0. Initialization
+// ----------------------
+//
+// Let the input argument x be
+//
+//     x = 2^m * ( 1. b_1 b_2 b_3 ... b_63 ),  63 <= m <= 16383.
+//
+// The first crucial step is to fetch four 64-bit portions of 2/pi.
+// To fulfill this goal, we calculate the bit position L of the
+// beginning of these 256-bit quantity by
+//
+//     L :=  62 - m.
+//
+// Note that -16321 <= L <= -1 because 63 <= m <= 16383; and that
+// the storage of 2/pi is adequate.
+//
+// Fetch P_1, P_2, P_3, P_4 beginning at bit position L thus:
+//
+//      bit position  L  L-1  L-2    ...  L-63
+//
+//      P_1    =      b   b    b     ...    b
+//
+// each b can be 0 or 1. Also, let P_0 be the two bits correspoding to
+// bit positions L+2 and L+1. So, when each of the P_j is interpreted
+// with appropriate scaling, we have
+//
+//      2/pi  =  P_big  + P_0 + (P_1 + P_2 + P_3 + P_4)  +  P_small
+//
+// Note that P_big and P_small can be ignored. The reasons are as follow.
+// First, consider P_big. If P_big = 0, we can certainly ignore it.
+// Otherwise, P_big >= 2^(L+3). Now,
+//
+//        P_big * ulp(x) >=  2^(L+3) * 2^(m-63)
+//                   >=  2^(65-m  +  m-63 )
+//                   >=  2^2
+//
+// Thus, P_big * x is an integer of the form 4*K. So
+//
+//       x = 4*K * (pi/2) + x*(P_0 + P_1 + P_2 + P_3 + P_4)*(pi/2)
+//                + x*P_small*(pi/2).
+//
+// Hence, P_big*x corresponds to information that can be ignored for
+// trigonometic function evaluation.
+//
+// Next, we must estimate the effect of ignoring P_small. The absolute
+// error made by ignoring P_small is bounded by
+//
+//       |P_small * x|  <=  ulp(P_4) * x
+//                  <=  2^(L-255) * 2^(m+1)
+//                  <=  2^(62-m-255 + m + 1)
+//                  <=  2^(-192)
+//
+// Since for double-extended precision, x * 2/pi = integer + f,
+// 0.5 >= |f| >= 2^(-75), the relative error introduced by ignoring
+// P_small is bounded by 2^(-192+75) <= 2^(-117), which is acceptable.
+//
+// Further note that if x is split into x_hi + x_lo where x_lo is the
+// two bits corresponding to bit positions 2^(m-62) and 2^(m-63); then
+//
+//       P_0 * x_hi
+//
+// is also an integer of the form 4*K; and thus can also be ignored.
+// Let M := P_0 * x_lo which is a small integer. The main part of the
+// calculation is really the multiplication of x with the four pieces
+// P_1, P_2, P_3, and P_4.
+//
+// Unless the reduced argument is extremely small in magnitude, it
+// suffices to carry out the multiplication of x with P_1, P_2, and
+// P_3. x*P_4 will be carried out and added on as a correction only
+// when it is found to be needed. Note also that x*P_4 need not be
+// computed exactly. A straightforward multiplication suffices since
+// the rounding error thus produced would be bounded by 2^(-3*64),
+// that is 2^(-192) which is small enough as the reduced argument
+// is bounded from below by 2^(-75).
+//
+// Now that we have four 64-bit data representing 2/pi and a
+// 64-bit x. We first need to calculate a highly accurate product
+// of x and P_1, P_2, P_3. This is best understood as integer
+// multiplication.
+//
+//
+// STEP 1. Multiplication

+//                    ---------   ---------   ---------
+//
+//                                            ---------
+//             X                              |   X   |
+//                                            ---------
+//      ----------------------------------------------------
+//
+//                                 ---------   ---------
+//                               |  A_hi |   |  A_lo |
+//                               ---------   ---------
+//

+//                   |  B_hi |   |  B_lo |
+//                   ---------   ---------
+//
+//
+//        ---------   ---------
+//       |  C_hi |   |  C_lo |
+//       ---------   ---------

+//       ---------   ---------   ---------   ---------
+//       |  S_0  |   |  S_1  |   |  S_2  |   |  S_3  |
+//       ---------   ---------   ---------   ---------
+//
+//
+//
+// STEP 2. Get N and f
+// -------------------
+//
+// Conceptually, after the individual pieces S_0, S_1, ..., are obtained,
+// we have to sum them and obtain an integer part, N, and a fraction, f.
+// Here, |f| <= 1/2, and N is an integer. Note also that N need only to
+// be known to module 2^k, k >= 2. In the case when |f| is small enough,
+// we would need to add in the value x*P_4.
+//
+//
+// STEP 3. Get reduced argument
+// ----------------------------
+//
+// The value f is not yet the reduced argument that we seek. The
+// equation
+//
+//       x * 2/pi = 4K  + N  + f
+//
+// says that
+//
+//         x   =  2*K*pi  + N * pi/2  +  f * (pi/2).
+//
+// Thus, the reduced argument is given by
+//
+//       reduced argument =  f * pi/2.
+//
+// This multiplication must be performed to extra precision.
+//
+// IV. Implementation
+// ==================
+//
+// Step 0. Initialization
+// ----------------------
+//
+// Set sgn_x := sign(x); x := |x|; x_lo := 2 lsb of x.
+//
+// In memory, 2/pi is stored contigously as
+//
+//  0x00000000 0x00000000 0xA2F....
+//                       ^
+//                       |__ implied binary bit
+//
+// Given x = 2^m * 1.xxxx...xxx; we calculate L := 62 - m. Thus
+// -1 <= L <= -16321. We fetch from memory 5 integer pieces of data.
+//
+// P_0 is the two bits corresponding to bit positions L+2 and L+1
+// P_1 is the 64-bit starting at bit position  L
+// P_2 is the 64-bit starting at bit position  L-64
+// P_3 is the 64-bit starting at bit position  L-128
+// P_4 is the 64-bit starting at bit position  L-192
+//
+// For example, if m = 63, P_0 would be 0 and P_1 would look like
+// 0xA2F...
+//
+// If m = 65, P_0 would be the two msb of 0xA, thus, P_0 is 10 in binary.
+// P_1 in binary would be  1 0 0 0 1 0 1 1 1 1 ....
+//
+// Step 1. Multiplication
+// ----------------------
+//
+// At this point, P_1, P_2, P_3, P_4 are integers. They are
+// supposed to be interpreted as
+//
+//  2^(L-63)     * P_1;
+//  2^(L-63-64)  * P_2;
+//  2^(L-63-128) * P_3;
+// 2^(L-63-192) * P_4;
+//
+// Since each of them need to be multiplied to x, we would scale
+// both x and the P_j's by some convenient factors: scale each
+// of P_j's up by 2^(63-L), and scale x down by 2^(L-63).
+//
+//   p_1 := fcvt.xf ( P_1 )
+//   p_2 := fcvt.xf ( P_2 ) * 2^(-64)
+//   p_3 := fcvt.xf ( P_3 ) * 2^(-128)
+//   p_4 := fcvt.xf ( P_4 ) * 2^(-192)
+//   x   := replace exponent of x by -1
+//          because 2^m    * 1.xxxx...xxx  * 2^(L-63)
+//          is      2^(-1) * 1.xxxx...xxx
+//
+// We are now faced with the task of computing the following

+// 02/10/03 Reordered header: .section, .global, .proc, .align
+// 08/08/03 Improved performance
+// 02/11/04 cis is moved to the separate file.
+// 03/31/05 Reformatted delimiters between data tables
+//
+// API
+//==============================================================
+// 1) void sincos(double, double*s, double*c)
+// 2) __libm_sincos - internal LIBM function, that accepts
+//    argument in f8 and returns cosine through f8, sine through f9
+//
+// Overview of operation
+//==============================================================
+//
+// Step 1
+// ======
+// Reduce x to region -1/2*pi/2^k ===== 0 ===== +1/2*pi/2^k  where k=4
+//    divide x by pi/2^k.
+//    Multiply by 2^k/pi.
+//    nfloat = Round result to integer (round-to-nearest)
+//
+// r = x -  nfloat * pi/2^k
+//    Do this as ((((x -  nfloat * HIGH(pi/2^k))) -
+//                        nfloat * LOW(pi/2^k)) -
+//                        nfloat * LOWEST(pi/2^k) for increased accuracy.
+//    pi/2^k is stored as two numbers that when added make pi/2^k.
+//       pi/2^k = HIGH(pi/2^k) + LOW(pi/2^k)
+//    HIGH and LOW parts are rounded to zero values,
+//    and LOWEST is rounded to nearest one.
+//
+// x = (nfloat * pi/2^k) + r
+//    r is small enough that we can use a polynomial approximation
+//    and is referred to as the reduced argument.
+//
+// Step 3
+// ======
+// Take the unreduced part and remove the multiples of 2pi.
+// So nfloat = nfloat (with lower k+1 bits cleared) + lower k+1 bits
+//
+//    nfloat (with lower k+1 bits cleared) is a multiple of 2^(k+1)
+//    N * 2^(k+1)
+//    nfloat * pi/2^k = N * 2^(k+1) * pi/2^k + (lower k+1 bits) * pi/2^k
+//    nfloat * pi/2^k = N * 2 * pi + (lower k+1 bits) * pi/2^k
+//    nfloat * pi/2^k = N2pi + M * pi/2^k
+//
+//
+// Sin(x) = Sin((nfloat * pi/2^k) + r)
+//        = Sin(nfloat * pi/2^k) * Cos(r) + Cos(nfloat * pi/2^k) * Sin(r)
+//
+//          Sin(nfloat * pi/2^k) = Sin(N2pi + Mpi/2^k)
+//                               = Sin(N2pi)Cos(Mpi/2^k) + Cos(N2pi)Sin(Mpi/2^k)
+//                               = Sin(Mpi/2^k)
+//
+//          Cos(nfloat * pi/2^k) = Cos(N2pi + Mpi/2^k)
+//                               = Cos(N2pi)Cos(Mpi/2^k) + Sin(N2pi)Sin(Mpi/2^k)
+//                               = Cos(Mpi/2^k)
+//
+// Sin(x) = Sin(Mpi/2^k) Cos(r) + Cos(Mpi/2^k) Sin(r)
+//
+//
+// Step 4
+// ======
+// 0 <= M < 2^(k+1)
+// There are 2^(k+1) Sin entries in a table.
+// There are 2^(k+1) Cos entries in a table.
+//
+// Get Sin(Mpi/2^k) and Cos(Mpi/2^k) by table lookup.
+//
+//
+// Step 5
+// ======
+// Calculate Cos(r) and Sin(r) by polynomial approximation.
+//
+// Cos(r) = 1 + r^2 q1  + r^4 q2 + r^6 q3 + ... = Series for Cos
+// Sin(r) = r + r^3 p1  + r^5 p2 + r^7 p3 + ... = Series for Sin
+//
+// and the coefficients q1, q2, ... and p1, p2, ... are stored in a table
+//
+//
+// Calculate
+// Sin(x) = Sin(Mpi/2^k) Cos(r) + Cos(Mpi/2^k) Sin(r)
+//
+// as follows
+//
+//    S[m] = Sin(Mpi/2^k) and C[m] = Cos(Mpi/2^k)
+//    rsq = r*r
+//
+//
+//    P = p1 + r^2p2 + r^4p3 + r^6p4
+//    Q = q1 + r^2q2 + r^4q3 + r^6q4
+//
+//       rcub = r * rsq
+//       Sin(r) = r + rcub * P
+//              = r + r^3p1  + r^5p2 + r^7p3 + r^9p4 + ... = Sin(r)
+//
+//            The coefficients are not exactly these values, but almost.
+//
+//            p1 = -1/6  = -1/3!
+//            p2 = 1/120 =  1/5!
+//            p3 = -1/5040 = -1/7!
+//            p4 = 1/362889 = 1/9!
+//
+//       P =  r + rcub * P
+//
+//    Answer = S[m] Cos(r) + C[m] P
+//
+//       Cos(r) = 1 + rsq Q
+//       Cos(r) = 1 + r^2 Q
+//       Cos(r) = 1 + r^2 (q1 + r^2q2 + r^4q3 + r^6q4)
+//       Cos(r) = 1 + r^2q1 + r^4q2 + r^6q3 + r^8q4 + ...
+//
+//       S[m] Cos(r) = S[m](1 + rsq Q)
+//       S[m] Cos(r) = S[m] + S[m] rsq Q
+//       S[m] Cos(r) = S[m] + s_rsq Q
+//       Q           = S[m] + s_rsq Q
+//
+// Then,
+//
+//    Answer = Q + C[m] P

+//  Mathematical Description
+//  ========================
+//
+//  The computation of FSIN and FCOS is best handled in one piece of
+//  code. The main reason is that given any argument Arg, computation
+//  of trigonometric functions first calculate N and an approximation
+//  to alpha where
+//
+//  Arg = N pi/2 + alpha, |alpha| <= pi/4.
+//
+//  Since
+//
+//  cos( Arg ) = sin( (N+1) pi/2 + alpha ),
+//
+//  therefore, the code for computing sine will produce cosine as long
+//  as 1 is added to N immediately after the argument reduction
+//  process.
+//
+//  Let M = N if sine
+//      N+1 if cosine.
+//
+//  Now, given
+//
+//  Arg = M pi/2  + alpha, |alpha| <= pi/4,
+//
+//  let I = M mod 4, or I be the two lsb of M when M is represented
+//  as 2's complement. I = [i_0 i_1]. Then
+//
+//  sin( Arg ) = (-1)^i_0  sin( alpha ) if i_1 = 0,
+//             = (-1)^i_0  cos( alpha )     if i_1 = 1.
+//
+//  For example:
+//       if M = -1, I = 11
+//         sin ((-pi/2 + alpha) = (-1) cos (alpha)
+//       if M = 0, I = 00
+//         sin (alpha) = sin (alpha)
+//       if M = 1, I = 01
+//         sin (pi/2 + alpha) = cos (alpha)
+//       if M = 2, I = 10
+//         sin (pi + alpha) = (-1) sin (alpha)
+//       if M = 3, I = 11
+//         sin ((3/2)pi + alpha) = (-1) cos (alpha)
+//
+//  The value of alpha is obtained by argument reduction and
+//  represented by two working precision numbers r and c where
+//
+//  alpha =  r  +  c     accurately.
+//
+//  The reduction method is described in a previous write up.
+//  The argument reduction scheme identifies 4 cases. For Cases 2
+//  and 4, because |alpha| is small, sin(r+c) and cos(r+c) can be
+//  computed very easily by 2 or 3 terms of the Taylor series
+//  expansion as follows:
+//
+//  Case 2:
+//  -------
+//
+//  sin(r + c) = r + c - r^3/6  accurately
+//  cos(r + c) = 1 - 2^(-67)    accurately
+//
+//  Case 4:
+//  -------
+//
+//  sin(r + c) = r + c - r^3/6 + r^5/120    accurately
+//  cos(r + c) = 1 - r^2/2 + r^4/24     accurately
+//
+//  The only cases left are Cases 1 and 3 of the argument reduction
+//  procedure. These two cases will be merged since after the
+//  argument is reduced in either cases, we have the reduced argument
+//  represented as r + c and that the magnitude |r + c| is not small
+//  enough to allow the usage of a very short approximation.
+//
+//  The required calculation is either
+//
+//  sin(r + c)  =  sin(r)  +  correction,  or
+//  cos(r + c)  =  cos(r)  +  correction.
+//
+//  Specifically,
+//
+//  sin(r + c) = sin(r) + c sin'(r) + O(c^2)
+//         = sin(r) + c cos (r) + O(c^2)
+//         = sin(r) + c(1 - r^2/2)  accurately.
+//  Similarly,
+//
+//  cos(r + c) = cos(r) - c sin(r) + O(c^2)
+//         = cos(r) - c(r - r^3/6)  accurately.
+//
+//  We therefore concentrate on accurately calculating sin(r) and
+//  cos(r) for a working-precision number r, |r| <= pi/4 to within
+//  0.1% or so.
+//
+//  The greatest challenge of this task is that the second terms of
+//  the Taylor series
+//
+//  r - r^3/3! + r^r/5! - ...
+//
+//  and
+//
+//  1 - r^2/2! + r^4/4! - ...
+//
+//  are not very small when |r| is close to pi/4 and the rounding
+//  errors will be a concern if simple polynomial accumulation is
+//  used. When |r| < 2^-3, however, the second terms will be small
+//  enough (6 bits or so of right shift) that a normal Horner
+//  recurrence suffices. Hence there are two cases that we consider
+//  in the accurate computation of sin(r) and cos(r), |r| <= pi/4.
+//
+//  Case small_r: |r| < 2^(-3)
+//  --------------------------
+//
+//  Since Arg = M pi/4 + r + c accurately, and M mod 4 is [i_0 i_1],
+//  we have
+//
+//  sin(Arg) = (-1)^i_0 * sin(r + c)    if i_1 = 0
+//       = (-1)^i_0 * cos(r + c)    if i_1 = 1
+//
+//  can be accurately approximated by
+//
+//  sin(Arg) = (-1)^i_0 * [sin(r) + c]  if i_1 = 0
+//           = (-1)^i_0 * [cos(r) - c*r] if i_1 = 1
+//
+//  because |r| is small and thus the second terms in the correction
+//  are unneccessary.
+//
+//  Finally, sin(r) and cos(r) are approximated by polynomials of
+//  moderate lengths.
+//
+//  sin(r) =  r + S_1 r^3 + S_2 r^5 + ... + S_5 r^11
+//  cos(r) =  1 + C_1 r^2 + C_2 r^4 + ... + C_5 r^10
+//
+//  We can make use of predicates to selectively calculate
+//  sin(r) or cos(r) based on i_1.
+//
+//  Case normal_r: 2^(-3) <= |r| <= pi/4
+//  ------------------------------------
+//
+//  This case is more likely than the previous one if one considers
+//  r to be uniformly distributed in [-pi/4 pi/4]. Again,
+//
+//  sin(Arg) = (-1)^i_0 * sin(r + c)    if i_1 = 0
+//           = (-1)^i_0 * cos(r + c)    if i_1 = 1.
+//
+//  Because |r| is now larger, we need one extra term in the
+//  correction. sin(Arg) can be accurately approximated by
+//
+//  sin(Arg) = (-1)^i_0 * [sin(r) + c(1-r^2/2)]      if i_1 = 0
+//           = (-1)^i_0 * [cos(r) - c*r*(1 - r^2/6)]    i_1 = 1.
+//
+//  Finally, sin(r) and cos(r) are approximated by polynomials of
+//  moderate lengths.
+//
+//  sin(r) =  r + PP_1_hi r^3 + PP_1_lo r^3 +
+//                PP_2 r^5 + ... + PP_8 r^17
+//
+//  cos(r) =  1 + QQ_1 r^2 + QQ_2 r^4 + ... + QQ_8 r^16
+//
+//  where PP_1_hi is only about 16 bits long and QQ_1 is -1/2.
+//  The crux in accurate computation is to calculate
+//
+//  r + PP_1_hi r^3   or  1 + QQ_1 r^2
+//
+//  accurately as two pieces: U_hi and U_lo. The way to achieve this
+//  is to obtain r_hi as a 10 sig. bit number that approximates r to
+//  roughly 8 bits or so of accuracy. (One convenient way is
+//
+//  r_hi := frcpa( frcpa( r ) ).)
+//
+//  This way,
+//
+//  r + PP_1_hi r^3 =  r + PP_1_hi r_hi^3 +
+//                          PP_1_hi (r^3 - r_hi^3)
+//              =  [r + PP_1_hi r_hi^3]  +
+//             [PP_1_hi (r - r_hi)
+//                (r^2 + r_hi r + r_hi^2) ]
+//              =  U_hi  +  U_lo
+//
+//  Since r_hi is only 10 bit long and PP_1_hi is only 16 bit long,
+//  PP_1_hi * r_hi^3 is only at most 46 bit long and thus computed
+//  exactly. Furthermore, r and PP_1_hi r_hi^3 are of opposite sign
+//  and that there is no more than 8 bit shift off between r and
+//  PP_1_hi * r_hi^3. Hence the sum, U_hi, is representable and thus
+//  calculated without any error. Finally, the fact that
+//
+//  |U_lo| <= 2^(-8) |U_hi|
+//
+//  says that U_hi + U_lo is approximating r + PP_1_hi r^3 to roughly
+//  8 extra bits of accuracy.
+//
+//  Similarly,
+//
+//  1 + QQ_1 r^2  =  [1 + QQ_1 r_hi^2]  +
+//                      [QQ_1 (r - r_hi)(r + r_hi)]
+//            =  U_hi  +  U_lo.
+//
+//  Summarizing, we calculate r_hi = frcpa( frcpa( r ) ).
+//
+//  If i_1 = 0, then
+//
+//    U_hi := r + PP_1_hi * r_hi^3
+//    U_lo := PP_1_hi * (r - r_hi) * (r^2 + r*r_hi + r_hi^2)
+//    poly := PP_1_lo r^3 + PP_2 r^5 + ... + PP_8 r^17
+//    correction := c * ( 1 + C_1 r^2 )
+//
+//  Else ...i_1 = 1
+//
+//    U_hi := 1 + QQ_1 * r_hi * r_hi
+//    U_lo := QQ_1 * (r - r_hi) * (r + r_hi)
+//    poly := QQ_2 * r^4 + QQ_3 * r^6 + ... + QQ_8 r^16
+//    correction := -c * r * (1 + S_1 * r^2)
+//
+//  End
+//
+//  Finally,
+//
+//  V := poly + ( U_lo + correction )
+//
+//                 /    U_hi  +  V         if i_0 = 0
+//  result := |
+//                 \  (-U_hi) -  V         if i_0 = 1
+//
+//  It is important that in the last step, negation of U_hi is
+//  performed prior to the subtraction which is to be performed in
+//  the user-set rounding mode.

+// History
+//==============================================================
+// 02/01/02 Initial version
+// 02/18/02 Large arguments processing routine is excluded.
+//          External interface entry points are added
+// 02/26/02 Added temporary return of results in r8, r9
+// 03/13/02 Corrected restore of predicate registers
+// 03/19/02 Added stack unwind around call to __libm_cisf_large
+// 09/05/02 Work range is widened by reduction strengthen (2 parts of Pi/16)
+// 02/10/03 Reordered header: .section, .global, .proc, .align
+// 02/11/04 cisf is moved to the separate file.
+// 03/31/05 Reformatted delimiters between data tables
+
+// API
+//==============================================================
+// 1) void sincosf(float, float*s, float*c)
+// 2) __libm_sincosf - internal LIBM function, that accepts
+//    argument in f8 and returns cosine through f8, sine through f9
+
+//
+// Overview of operation
+//==============================================================
+//
+// Step 1
+// ======
+// Reduce x to region -1/2*pi/2^k ===== 0 ===== +1/2*pi/2^k  where k=4
+//    divide x by pi/2^k.
+//    Multiply by 2^k/pi.
+//    nfloat = Round result to integer (round-to-nearest)
+//
+// r = x -  nfloat * pi/2^k
+//    Do this as (x -  nfloat * HIGH(pi/2^k)) - nfloat * LOW(pi/2^k) for increased accuracy.
+//    pi/2^k is stored as two numbers that when added make pi/2^k.
+//       pi/2^k = HIGH(pi/2^k) + LOW(pi/2^k)
+//    HIGH part is rounded to zero, LOW - to nearest
+//
+// x = (nfloat * pi/2^k) + r
+//    r is small enough that we can use a polynomial approximation
+//    and is referred to as the reduced argument.
+//
+// Step 3
+// ======
+// Take the unreduced part and remove the multiples of 2pi.
+// So nfloat = nfloat (with lower k+1 bits cleared) + lower k+1 bits
+//
+//    nfloat (with lower k+1 bits cleared) is a multiple of 2^(k+1)
+//    N * 2^(k+1)
+//    nfloat * pi/2^k = N * 2^(k+1) * pi/2^k + (lower k+1 bits) * pi/2^k
+//    nfloat * pi/2^k = N * 2 * pi + (lower k+1 bits) * pi/2^k
+//    nfloat * pi/2^k = N2pi + M * pi/2^k
+//
+//
+// Sin(x) = Sin((nfloat * pi/2^k) + r)
+//        = Sin(nfloat * pi/2^k) * Cos(r) + Cos(nfloat * pi/2^k) * Sin(r)
+//
+//          Sin(nfloat * pi/2^k) = Sin(N2pi + Mpi/2^k)
+//                               = Sin(N2pi)Cos(Mpi/2^k) + Cos(N2pi)Sin(Mpi/2^k)
+//                               = Sin(Mpi/2^k)
+//
+//          Cos(nfloat * pi/2^k) = Cos(N2pi + Mpi/2^k)
+//                               = Cos(N2pi)Cos(Mpi/2^k) + Sin(N2pi)Sin(Mpi/2^k)
+//                               = Cos(Mpi/2^k)
+//
+// Sin(x) = Sin(Mpi/2^k) Cos(r) + Cos(Mpi/2^k) Sin(r)
+//
+//
+// Step 4
+// ======
+// 0 <= M < 2^(k+1)
+// There are 2^(k+1) Sin entries in a table.
+// There are 2^(k+1) Cos entries in a table.
+//
+// Get Sin(Mpi/2^k) and Cos(Mpi/2^k) by table lookup.
+//
+//
+// Step 5
+// ======
+// Calculate Cos(r) and Sin(r) by polynomial approximation.
+//
+// Cos(r) = 1 + r^2 q1  + r^4 q2 = Series for Cos
+// Sin(r) = r + r^3 p1  + r^5 p2 = Series for Sin
+//
+// and the coefficients q1, q2 and p1, p2 are stored in a table
+//
+//
+// Calculate
+// Sin(x) = Sin(Mpi/2^k) Cos(r) + Cos(Mpi/2^k) Sin(r)
+//
+// as follows
+//
+//    S[m] = Sin(Mpi/2^k) and C[m] = Cos(Mpi/2^k)
+//    rsq = r*r
+//
+//
+//    P = p1 + r^2p2
+//    Q = q1 + r^2q2
+//
+//       rcub = r * rsq
+//       Sin(r) = r + rcub * P
+//              = r + r^3p1  + r^5p2 = Sin(r)
+//
+//       P =  r + rcub * P
+//
+//    Answer = S[m] Cos(r) + C[m] P
+//
+//       Cos(r) = 1 + rsq Q
+//       Cos(r) = 1 + r^2 Q
+//       Cos(r) = 1 + r^2 (q1 + r^2q2)
+//       Cos(r) = 1 + r^2q1 + r^4q2
+//
+//       S[m] Cos(r) = S[m](1 + rsq Q)
+//       S[m] Cos(r) = S[m] + S[m] rsq Q
+//       S[m] Cos(r) = S[m] + s_rsq Q
+//       Q           = S[m] + s_rsq Q
+//
+// Then,
+//

+//  Mathematical Description
+//  ========================
+//
+//  The computation of FSIN and FCOS performed in parallel.
+//
+//  Arg = N pi/2 + alpha, |alpha| <= pi/4.
+//
+//  cosl( Arg ) = sinl( (N+1) pi/2 + alpha ),
+//
+//  therefore, the code for computing sine will produce cosine as long
+//  as 1 is added to N immediately after the argument reduction
+//  process.
+//
+//  Let M = N if sine
+//      N+1 if cosine.
+//
+//  Now, given
+//
+//  Arg = M pi/2  + alpha, |alpha| <= pi/4,
+//
+//  let I = M mod 4, or I be the two lsb of M when M is represented
+//  as 2's complement. I = [i_0 i_1]. Then
+//
+//  sinl( Arg ) = (-1)^i_0  sinl( alpha ) if i_1 = 0,
+//             = (-1)^i_0  cosl( alpha )     if i_1 = 1.
+//
+//  For example:
+//       if M = -1, I = 11
+//         sin ((-pi/2 + alpha) = (-1) cos (alpha)
+//       if M = 0, I = 00
+//         sin (alpha) = sin (alpha)
+//       if M = 1, I = 01
+//         sin (pi/2 + alpha) = cos (alpha)
+//       if M = 2, I = 10
+//         sin (pi + alpha) = (-1) sin (alpha)
+//       if M = 3, I = 11
+//         sin ((3/2)pi + alpha) = (-1) cos (alpha)
+//
+//  The value of alpha is obtained by argument reduction and
+//  represented by two working precision numbers r and c where
+//
+//  alpha =  r  +  c     accurately.
+//
+//  The reduction method is described in a previous write up.
+//  The argument reduction scheme identifies 4 cases. For Cases 2
+//  and 4, because |alpha| is small, sinl(r+c) and cosl(r+c) can be
+//  computed very easily by 2 or 3 terms of the Taylor series
+//  expansion as follows:
+//
+//  Case 2:
+//  -------
+//
+//  sinl(r + c) = r + c - r^3/6 accurately
+//  cosl(r + c) = 1 - 2^(-67) accurately
+//
+//  Case 4:
+//  -------
+//
+//  sinl(r + c) = r + c - r^3/6 + r^5/120 accurately
+//  cosl(r + c) = 1 - r^2/2 + r^4/24    accurately
+//
+//  The only cases left are Cases 1 and 3 of the argument reduction
+//  procedure. These two cases will be merged since after the
+//  argument is reduced in either cases, we have the reduced argument
+//  represented as r + c and that the magnitude |r + c| is not small
+//  enough to allow the usage of a very short approximation.
+//
+//  The required calculation is either
+//
+//  sinl(r + c)  =  sinl(r)  +  correction,  or
+//  cosl(r + c)  =  cosl(r)  +  correction.
+//
+//  Specifically,
+//
+//  sinl(r + c) = sinl(r) + c sin'(r) + O(c^2)
+//       = sinl(r) + c cos (r) + O(c^2)
+//       = sinl(r) + c(1 - r^2/2)  accurately.
+//  Similarly,
+//
+//  cosl(r + c) = cosl(r) - c sinl(r) + O(c^2)
+//       = cosl(r) - c(r - r^3/6)  accurately.
+//
+//  We therefore concentrate on accurately calculating sinl(r) and
+//  cosl(r) for a working-precision number r, |r| <= pi/4 to within
+//  0.1% or so.
+//
+//  The greatest challenge of this task is that the second terms of
+//  the Taylor series
+//
+//  r - r^3/3! + r^r/5! - ...
+//
+//  and
+//
+//  1 - r^2/2! + r^4/4! - ...
+//
+//  are not very small when |r| is close to pi/4 and the rounding
+//  errors will be a concern if simple polynomial accumulation is
+//  used. When |r| < 2^-3, however, the second terms will be small
+//  enough (6 bits or so of right shift) that a normal Horner
+//  recurrence suffices. Hence there are two cases that we consider
+//  in the accurate computation of sinl(r) and cosl(r), |r| <= pi/4.
+//
+//  Case small_r: |r| < 2^(-3)
+//  --------------------------
+//
+//  Since Arg = M pi/4 + r + c accurately, and M mod 4 is [i_0 i_1],
+//  we have
+//
+//  sinl(Arg) = (-1)^i_0 * sinl(r + c)  if i_1 = 0
+//     = (-1)^i_0 * cosl(r + c)   if i_1 = 1
+//
+//  can be accurately approximated by
+//
+//  sinl(Arg) = (-1)^i_0 * [sinl(r) + c]  if i_1 = 0
+//           = (-1)^i_0 * [cosl(r) - c*r] if i_1 = 1
+//
+//  because |r| is small and thus the second terms in the correction
+//  are unneccessary.
+//
+//  Finally, sinl(r) and cosl(r) are approximated by polynomials of
+//  moderate lengths.
+//
+//  sinl(r) =  r + S_1 r^3 + S_2 r^5 + ... + S_5 r^11
+//  cosl(r) =  1 + C_1 r^2 + C_2 r^4 + ... + C_5 r^10
+//
+//  We can make use of predicates to selectively calculate
+//  sinl(r) or cosl(r) based on i_1.
+//
+//  Case normal_r: 2^(-3) <= |r| <= pi/4
+//  ------------------------------------
+//
+//  This case is more likely than the previous one if one considers
+//  r to be uniformly distributed in [-pi/4 pi/4]. Again,
+//
+//  sinl(Arg) = (-1)^i_0 * sinl(r + c)  if i_1 = 0
+//           = (-1)^i_0 * cosl(r + c)   if i_1 = 1.
+//
+//  Because |r| is now larger, we need one extra term in the
+//  correction. sinl(Arg) can be accurately approximated by
+//
+//  sinl(Arg) = (-1)^i_0 * [sinl(r) + c(1-r^2/2)]      if i_1 = 0
+//           = (-1)^i_0 * [cosl(r) - c*r*(1 - r^2/6)]    i_1 = 1.
+//
+//  Finally, sinl(r) and cosl(r) are approximated by polynomials of
+//  moderate lengths.
+//
+//  sinl(r) =  r + PP_1_hi r^3 + PP_1_lo r^3 +
+//                PP_2 r^5 + ... + PP_8 r^17
+//
+//  cosl(r) =  1 + QQ_1 r^2 + QQ_2 r^4 + ... + QQ_8 r^16
+//
+//  where PP_1_hi is only about 16 bits long and QQ_1 is -1/2.
+//  The crux in accurate computation is to calculate
+//
+//  r + PP_1_hi r^3   or  1 + QQ_1 r^2
+//
+//  accurately as two pieces: U_hi and U_lo. The way to achieve this
+//  is to obtain r_hi as a 10 sig. bit number that approximates r to
+//  roughly 8 bits or so of accuracy. (One convenient way is
+//
+//  r_hi := frcpa( frcpa( r ) ).)
+//
+//  This way,
+//
+//  r + PP_1_hi r^3 =  r + PP_1_hi r_hi^3 +
+//                          PP_1_hi (r^3 - r_hi^3)
+//            =  [r + PP_1_hi r_hi^3]  +
+//         [PP_1_hi (r - r_hi)
+//            (r^2 + r_hi r + r_hi^2) ]
+//            =  U_hi  +  U_lo
+//
+//  Since r_hi is only 10 bit long and PP_1_hi is only 16 bit long,
+//  PP_1_hi * r_hi^3 is only at most 46 bit long and thus computed
+//  exactly. Furthermore, r and PP_1_hi r_hi^3 are of opposite sign
+//  and that there is no more than 8 bit shift off between r and
+//  PP_1_hi * r_hi^3. Hence the sum, U_hi, is representable and thus
+//  calculated without any error. Finally, the fact that
+//
+//  |U_lo| <= 2^(-8) |U_hi|
+//
+//  says that U_hi + U_lo is approximating r + PP_1_hi r^3 to roughly
+//  8 extra bits of accuracy.
+//
+//  Similarly,
+//
+//  1 + QQ_1 r^2  =  [1 + QQ_1 r_hi^2]  +
+//                      [QQ_1 (r - r_hi)(r + r_hi)]
+//          =  U_hi  +  U_lo.
+//
+//  Summarizing, we calculate r_hi = frcpa( frcpa( r ) ).
+//
+//  If i_1 = 0, then
+//
+//    U_hi := r + PP_1_hi * r_hi^3
+//    U_lo := PP_1_hi * (r - r_hi) * (r^2 + r*r_hi + r_hi^2)
+//    poly := PP_1_lo r^3 + PP_2 r^5 + ... + PP_8 r^17
+//    correction := c * ( 1 + C_1 r^2 )
+//
+//  Else ...i_1 = 1
+//
+//    U_hi := 1 + QQ_1 * r_hi * r_hi
+//    U_lo := QQ_1 * (r - r_hi) * (r + r_hi)
+//    poly := QQ_2 * r^4 + QQ_3 * r^6 + ... + QQ_8 r^16
+//    correction := -c * r * (1 + S_1 * r^2)
+//
+//  End
+//
+//  Finally,
+//
+//  V := poly + ( U_lo + correction )
+//
+//                 /    U_hi  +  V         if i_0 = 0
+//  result := |
+//                 \  (-U_hi) -  V         if i_0 = 1
+//
+//  It is important that in the last step, negation of U_hi is
+//  performed prior to the subtraction which is to be performed in
+//  the user-set rounding mode.

+// Mathematical Description
+//
+// We consider the computation of FPTAN of Arg. Now, given
+//
+//      Arg = N pi/2  + alpha,          |alpha| <= pi/4,
+//
+// basic mathematical relationship shows that
+//
+//      tan( Arg ) =  tan( alpha )     if N is even;
+//                 = -cot( alpha )      otherwise.
+//
+// The value of alpha is obtained by argument reduction and
+// represented by two working precision numbers r and c where
+//
+//      alpha =  r  +  c     accurately.
+//
+// The reduction method is described in a previous write up.
+// The argument reduction scheme identifies 4 cases. For Cases 2
+// and 4, because |alpha| is small, tan(r+c) and -cot(r+c) can be
+// computed very easily by 2 or 3 terms of the Taylor series
+// expansion as follows:
+//
+// Case 2:
+// -------
+//
+//      tan(r + c) = r + c + r^3/3          ...accurately
+//        -cot(r + c) = -1/(r+c) + r/3          ...accurately
+//
+// Case 4:
+// -------
+//
+//      tan(r + c) = r + c + r^3/3 + 2r^5/15     ...accurately
+//        -cot(r + c) = -1/(r+c) + r/3 + r^3/45     ...accurately
+//
+//
+// The only cases left are Cases 1 and 3 of the argument reduction
+// procedure. These two cases will be merged since after the
+// argument is reduced in either cases, we have the reduced argument
+// represented as r + c and that the magnitude |r + c| is not small
+// enough to allow the usage of a very short approximation.
+//
+// The greatest challenge of this task is that the second terms of
+// the Taylor series for tan(r) and -cot(r)
+//
+//      r + r^3/3 + 2 r^5/15 + ...
+//
+// and
+//
+//      -1/r + r/3 + r^3/45 + ...
+//
+// are not very small when |r| is close to pi/4 and the rounding
+// errors will be a concern if simple polynomial accumulation is
+// used. When |r| < 2^(-2), however, the second terms will be small
+// enough (5 bits or so of right shift) that a normal Horner
+// recurrence suffices. Hence there are two cases that we consider
+// in the accurate computation of tan(r) and cot(r), |r| <= pi/4.
+//
+// Case small_r: |r| < 2^(-2)
+// --------------------------
+//
+// Since Arg = N pi/4 + r + c accurately, we have
+//
+//      tan(Arg) =  tan(r+c)            for N even,
+//            = -cot(r+c)          otherwise.
+//
+// Here for this case, both tan(r) and -cot(r) can be approximated
+// by simple polynomials:
+//
+//      tan(r) =    r + P1_1 r^3 + P1_2 r^5 + ... + P1_9 r^19
+//        -cot(r) = -1/r + Q1_1 r   + Q1_2 r^3 + ... + Q1_7 r^13
+//
+// accurately. Since |r| is relatively small, tan(r+c) and
+// -cot(r+c) can be accurately approximated by replacing r with
+// r+c only in the first two terms of the corresponding polynomials.
+//
+// Note that P1_1 (and Q1_1 for that matter) approximates 1/3 to
+// almost 64 sig. bits, thus
+//
+//      P1_1 (r+c)^3 =  P1_1 r^3 + c * r^2     accurately.
+//
+// Hence,
+//
+//      tan(r+c) =    r + P1_1 r^3 + P1_2 r^5 + ... + P1_9 r^19
+//                     + c*(1 + r^2)
+//
+//        -cot(r+c) = -1/(r+c) + Q1_1 r   + Q1_2 r^3 + ... + Q1_7 r^13
+//               + Q1_1*c
+//
+//
+// Case normal_r: 2^(-2) <= |r| <= pi/4
+// ------------------------------------
+//
+// This case is more likely than the previous one if one considers
+// r to be uniformly distributed in [-pi/4 pi/4].
+//
+// The required calculation is either
+//
+//      tan(r + c)  =  tan(r)  +  correction,  or
+//        -cot(r + c)  = -cot(r)  +  correction.
+//
+// Specifically,

+// We will employ a table-driven approach. Let

+// the form
+//
+//      tan(x)  as  x  +  x * P, where
+//           P  =   x^2 * (P2_1 + x^2 * (P2_2 + x^2 * P2_3))
+//
+// Because |x| <= 2^(-7), tan(B) + x approximates tan(B) + tan(x)
+// to a relative accuracy better than 2^(-18). Thus, a good
+// initial guess of 1/( tan(B) + tan(x) ) to initiate the iterative
+// division is:
+//
+//      1/(tan(B) + tan(x))      is approximately
+//      1/(tan(B) +   x)         is
+//      cot(B)/(1 + x*cot(B))    is approximately
+//      C_hi / ( 1 + C_hi * x )  is approximately
+//
+//      C_hi * [ 1 - (C_hi * x) + (C_hi * x)^2 ]
+//
+// The calculation of -cot(r+c) therefore proceed as follows:

+//      Cx     := C_hi * x

+//      P     := xsq * (P1_1 + xsq*(P1_2 + xsq*P1_3))
+//      ...V_hi serves as an initial guess of 1/(tan(B) + tan(x))
+//         ...good to about 18 bits of accuracy
+//
+//      tanx     := x + x*P
+//      D     := T_hi + tanx
+//      ...D is a double precision denominator: tan(B) + tan(x)
+//
+//      V_hi     := V_hi + V_hi*(1 - V_hi*D)
+//      ....V_hi approximates 1/(tan(B)+tan(x)) to 40 bits
+//
+//      V_lo     := V_hi * ( [ (1 - V_hi*T_hi) - V_hi*tanx ]
+//                           - V_hi*T_lo )   ...observe all order
+//         ...V_hi + V_lo approximates 1/(tan(B) + tan(x))

+// 3. Implementation Notes
+// =======================
+//
+//   Table entries T_hi, T_lo; C_hi, C_lo; SC_inv
+//
+//   Recall that 2^(-2) <= |r| <= pi/4;
+//
+//      r = sgn_r * 2^k * 1.b_1 b_2 ... b_63
+//
+//   and
+//
+//        B = 2^k * 1.b_1 b_2 b_3 b_4 b_5 1
+//
+//   Thus, for k = -2, possible values of B are
+//
+//          B = 2^(-2) * ( 1 + index/32  +  1/64 ),
+//      index ranges from 0 to 31
+//
+//   For k = -1, however, since |r| <= pi/4 = 0.78...
+//   possible values of B are
+//
+//        B = 2^(-1) * ( 1 + index/32  +  1/64 )
+//      index ranges from 0 to 19.

+// double asinh(double)
+//
+// Overview of operation
+// ==============================================================
+//
+// There are 7 paths:
+// 1. x = 0.0
+//    Return asinh(x) = 0.0
+//
+// 2. 0.0 <|x| < 2^(-3)
+//    Return asinh(x) = POL13(x),
+//         where POL13(x) = (x^2*C13 + ...)*x^2 + C5)*x^2 + C3)*x^3 + x
+//
+// 3. 2^(-3) <= |x| < 2^63
+//    Return asinh(x) = sign(x)*(log(|x| + sqrt(x^2 + 1.0)))
+//    To compute x + sqrt(x^2 + 1.0) modified Newton Raphson method is used
+//      (3 iterations)
+//    Algorithm description for log function see below.
+//
+// 4. 2^63 <= |x| < +INF
+//    Return asinh(x) = sign(x)*log(2*|x|)
+//    Algorithm description for log function see below.
+//
+// 5. x = INF
+//    Return asinh(x) = INF
+//
+// 6. x = [S,Q]NaN
+//    Return asinh(x) = QNaN
+//
+// 7. x = denormal
+//    Return asinh(x) = x correctly rounded
+//
+//==============================================================
+// Algorithm Description for log(x) function
+// Below we are using the fact that inequality x - 1.0 > 2^(-6) is always
+//   true for this asinh implementation
+//
+// Consider  x = 2^N 1.f1 f2 f3 f4...f63
+// Log(x) = log(frcpa(x) x/frcpa(x))
+//        = log(1/frcpa(x)) + log(frcpa(x) x)
+//        = -log(frcpa(x)) + log(frcpa(x) x)
+//
+// frcpa(x)       = 2^-N frcpa((1.f1 f2 ... f63)
+//
+// -log(frcpa(x)) = -log(C)
+//                = -log(2^-N) - log(frcpa(1.f1 f2 ... f63))
+//
+// -log(frcpa(x)) = -log(C)
+//                = +Nlog2 - log(frcpa(1.f1 f2 ... f63))
+//
+// -log(frcpa(x)) = -log(C)
+//                = +Nlog2 + log(frcpa(1.f1 f2 ... f63))
+//
+// Log(x) = log(1/frcpa(x)) + log(frcpa(x) x)
+//
+// Log(x) =  +Nlog2 + log(1./frcpa(1.f1 f2 ... f63)) + log(frcpa(x) x)
+// Log(x) =  +Nlog2 - log(/frcpa(1.f1 f2 ... f63))   + log(frcpa(x) x)
+// Log(x) =  +Nlog2 + T                              + log(frcpa(x) x)
+//
+// Log(x) =  +Nlog2 + T                     + log(C x)
+//
+// Cx = 1 + r
+//
+// Log(x) =  +Nlog2 + T  + log(1+r)
+// Log(x) =  +Nlog2 + T  + Series( r - r^2/2 + r^3/3 - r^4/4 ....)
+//
+// 1.f1 f2 ... f8 has 256 entries.
+// They are 1 + k/2^8, k = 0 ... 255
+// These 256 values are the table entries.
+//
+// Implementation
+//==============================================================
+// C = frcpa(x)
+// r = C * x - 1
+//
+// Form rseries = r + P1*r^2 + P2*r^3 + P3*r^4 + P4*r^5 + P5*r^6
+//
+// x = f * 2*n where f is 1.f_1f_2f_3....f_63
+// Nfloat = float(n)  where n is the true unbiased exponent
+// pre-index = f_1f_2....f_8
+// index = pre_index * 16
+// get the dxt table entry at index + offset = T
+//
+// result = (T + Nfloat * log(2)) + rseries
+//
+// The T table is calculated as follows
+// Form x_k = 1 + k/2^8 where k goes from 0... 255
+//      y_k = frcpa(x_k)
+//      log(1/y_k)  in quad and round to double-extended
+//
+//

+// f9 -> f15,  f32 -> f68

+//==============================================================
+// Algorithm Description for log(x) function
+// Below we are using the fact that inequality x - 1.0 > 2^(-6) is always
+// true for this asinh implementation
+//
+// Consider  x = 2^N 1.f1 f2 f3 f4...f63
+// Log(x) = log(frcpa(x) x/frcpa(x))
+//        = log(1/frcpa(x)) + log(frcpa(x) x)
+//        = -log(frcpa(x)) + log(frcpa(x) x)
+//
+// frcpa(x)       = 2^-N frcpa((1.f1 f2 ... f63)
+//
+// -log(frcpa(x)) = -log(C)
+//                = -log(2^-N) - log(frcpa(1.f1 f2 ... f63))
+//
+// -log(frcpa(x)) = -log(C)
+//                = +Nlog2 - log(frcpa(1.f1 f2 ... f63))
+//
+// -log(frcpa(x)) = -log(C)
+//                = +Nlog2 + log(frcpa(1.f1 f2 ... f63))
+//
+// Log(x) = log(1/frcpa(x)) + log(frcpa(x) x)
+//
+// Log(x) =  +Nlog2 + log(1./frcpa(1.f1 f2 ... f63)) + log(frcpa(x) x)
+// Log(x) =  +Nlog2 - log(/frcpa(1.f1 f2 ... f63))   + log(frcpa(x) x)
+// Log(x) =  +Nlog2 + T                              + log(frcpa(x) x)
+//
+// Log(x) =  +Nlog2 + T                     + log(C x)
+//
+// Cx = 1 + r
+//
+// Log(x) =  +Nlog2 + T  + log(1+r)
+// Log(x) =  +Nlog2 + T  + Series( r - r^2/2 + r^3/3 - r^4/4 ....)
+//
+// 1.f1 f2 ... f8 has 256 entries.
+// They are 1 + k/2^8, k = 0 ... 255
+// These 256 values are the table entries.
+//
+// Implementation
+//==============================================================
+// C = frcpa(x)
+// r = C * x - 1
+//
+// Form rseries = r + P1*r^2 + P2*r^3 + P3*r^4
+//
+// x = f * 2*n where f is 1.f_1f_2f_3....f_63
+// Nfloat = float(n)  where n is the true unbiased exponent
+// pre-index = f_1f_2....f_8
+// index = pre_index * 8
+// get the dxt table entry at index + offset = T
+//
+// result = (T + Nfloat * log(2)) + rseries
+//
+// The T table is calculated as follows
+// Form x_k = 1 + k/2^8 where k goes from 0... 255
+//      y_k = frcpa(x_k)
+//      log(1/y_k)  in quad and round to double-extended

+// Main path algorithm
+// ( thanks to Peter Markstein for the idea of sqrt(x^2+1) computation! )
+// *************************************************************************
+//
+// There are 3 parts of x+sqrt(x^2+1) computation:
+//
+//  1) p2 = (p2_hi+p2_lo) = x^2+1 obtaining
+//     ------------------------------------
+//     p2_hi = x2_hi + 1, where x2_hi = x * x;
+//     p2_lo = x2_lo + p1_lo, where
+//                            x2_lo = FMS(x*x-x2_hi),
+//                            p1_lo = (1 - p2_hi) + x2_hi;
+//
+//  2) g = (g_hi+g_lo) = sqrt(p2) = sqrt(p2_hi+p2_lo)
+//     ----------------------------------------------
+//     r = invsqrt(p2_hi) (8-bit reciprocal square root approximation);
+//     g = p2_hi * r (first 8 bit-approximation of sqrt);
+//
+//     h = 0.5 * r;
+//     e = 0.5 - g * h;
+//     g = g * e + g (second 16 bit-approximation of sqrt);
+//
+//     h = h * e + h;
+//     e = 0.5 - g * h;
+//     g = g * e + g (third 32 bit-approximation of sqrt);
+//
+//     h = h * e + h;
+//     e = 0.5 - g * h;
+//     g_hi = g * e + g (fourth 64 bit-approximation of sqrt);
+//
+//     Remainder computation:
+//     h = h * e + h;
+//     d = (p2_hi - g_hi * g_hi) + p2_lo;
+//     g_lo = d * h;
+//
+//  3) b = (b_hi + b_lo) = x + g, where g = (g_hi + g_lo) = sqrt(x^2+1)
+//     -------------------------------------------------------------------
+//     b_hi = (g_hi + x) + gl;
+//     b_lo = (g_hi - b_hi) + x + gl;
+//
+//  Now we pass b presented as sum b_hi + b_lo to special version
+//  of logl function which accept a pair of arguments as
+//  'mutiprecision' value.
+//
+//  Special log algorithm overview
+//  ================================
+//   Here we use a table lookup method. The basic idea is that in
+//   order to compute logl(Arg) = logl (Arg-1) for an argument Arg in [1,2),
+//   we construct a value G such that G*Arg is close to 1 and that
+//   logl(1/G) is obtainable easily from a table of values calculated
+//   beforehand. Thus
+//
+//      logl(Arg) = logl(1/G) + logl((G*Arg - 1))
+//
+//   Because |G*Arg - 1| is small, the second term on the right hand
+//   side can be approximated by a short polynomial. We elaborate
+//   this method in four steps.
+//
+//   Step 0: Initialization
+//
+//   We need to calculate logl( X ). Obtain N, S_hi such that
+//
+//      X = 2^N * ( S_hi + S_lo )   exactly
+//
+//   where S_hi in [1,2) and S_lo is a correction to S_hi in the sense
+//   that |S_lo| <= ulp(S_hi).
+//
+//   For the special version of logl: S_lo = b_lo
+//   !-----------------------------------------------!
+//
+//   Step 1: Argument Reduction
+//
+//   Based on S_hi, obtain G_1, G_2, G_3 from a table and calculate
+//
+//      G := G_1 * G_2 * G_3
+//      r := (G * S_hi - 1) + G * S_lo
+//
+//   These G_j's have the property that the product is exactly
+//   representable and that |r| < 2^(-12) as a result.
+//
+//   Step 2: Approximation
+//
+//   logl(1 + r) is approximated by a short polynomial poly(r).
+//
+//   Step 3: Reconstruction
+//
+//   Finally,
+//
+//   logl( X )   =   logl( 2^N * (S_hi + S_lo) )
+//                 ~=~  N*logl(2) + logl(1/G) + logl(1 + r)
+//                 ~=~  N*logl(2) + logl(1/G) + poly(r).
+//
+//   For detailed description see logl or log1pl function, regular path.

+// History
+//==============================================================
+// 02/02/00  Initial version
+// 04/13/00  Improved speed
+// 04/19/00  Removed the qualifying predicate from the fmerge.s that
+//           takes the absolute value.
+// 06/16/00  Reassigned FP registers to eliminate stalls on loads
+// 08/30/00  Saved 5 cycles in main path by rearranging large argument logic
+//           and delaying use of result of fcmp in load by 1 group
+// 05/20/02  Cleaned up namespace and sf0 syntax
+// 08/20/02  Use atan2 algorithm with x=1 for better accuracy
+// 02/06/03  Reordered header: .section, .global, .proc, .align

+//
+// Overview of operation
+//==============================================================
+//
+// The atan function returns values in the interval [-pi/2,+pi/2].
+//
+// The algorithm used is the atan2(Y,X) algorithm where we fix X=1.0.
+//
+// There are two basic paths: swap true and swap false.
+// atan2(Y,X) ==> atan2(V/U) where U >= V. If Y > X, we must swap.
+//
+// p6  swap True    |Y| > |X|
+// p7  swap False   |Y| <= |X|
+//
+//
+// Simple trigonometric identities show
+//   Region 1
+//         |Y|<=1.0, V=Y, U=1.0     atan2(Y,X) = sgnY * (0 + atan(V/U))
+//
+//   Region 2
+//         |Y|>1.0, V=1.0, U=Y      atan2(Y,X) = sgnY * (pi/2 - atan(V/U))
+//
+//
+// We compute atan(V/U) from the identity
+//      atan(z) + atan([(V/U)-z] / [1+(V/U)z])
+//      where z is a limited precision approximation (16 bits) to V/U
+//
+// z is calculated with the assistance of the frcpa instruction.
+//
+// atan(z) is calculated by a polynomial z + z^3 * p(w),  w=z^2
+// where p(w) = P0+P1*w+...+P22*w^22
+//
+// Let d = [(V/U)-z] / [1+(V/U)z]) = (V-U*z)/(U+V*z)
+//
+// Approximate atan(d) by d + P0*d^3
+// Let F = 1/(U+V*z) * (1-a), where |a|< 2^-8.8.
+// Compute q(a) = 1 + a + ... + a^5.
+// Then F*q(a) approximates the reciprocal to more than 50 bits.

+//==============================================================
+// 02/20/00 Initial version
+// 08/17/00 Changed predicate register macro-usage to direct predicate
+//          names due to an assembler bug.
+// 02/06/02 Corrected .section statement
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 02/06/03 Reordered header: .section, .global, .proc, .align;
+//          added missing bundling
+
+//
+// Assembly macros

+// Mathematical Description
+// ---------------------------
+//
+// The function ATANL( Arg_Y, Arg_X ) returns the "argument"
+// or the "phase" of the complex number
+//
+//           Arg_X + i Arg_Y
+//
+// or equivalently, the angle in radians from the positive
+// x-axis to the line joining the origin and the point
+// (Arg_X,Arg_Y)
+//
+//
+//        (Arg_X, Arg_Y) x
+//                        \
+//                \
+//                 \
+//                  \
+//                   \ angle between is ATANL(Arg_Y,Arg_X)
+
+
+
+
+//                    \
+//                     ------------------> X-axis
+
+//                   Origin
+//
+// Moreover, this angle is reported in the range [-pi,pi] thus
+//
+//      -pi <= ATANL( Arg_Y, Arg_X ) <= pi.
+//
+// From the geometry, it is easy to define ATANL when one of
+// Arg_X or Arg_Y is +-0 or +-inf:
+//
+//
+//      \ Y |
+//     X \  |  +0  | -0  |  +inf |  -inf  |  finite non-zero
+//        \ |      |     |       |        |
+//    ______________________________________________________
+//          |            |       |        |
+//     +-0  |   Invalid/ |  pi/2 | -pi/2  |  sign(Y)*pi/2
+//          |    qNaN    |       |        |

+//  non-zero| sign(Y)*0: |       |        |
+//       | sign(Y)*pi |       |        |
+//
+//
+// One must take note that ATANL is NOT the arctangent of the
+// value Arg_Y/Arg_X; but rather ATANL and arctan are related
+// in a slightly more complicated way as follows:
+//
+// Let U := max(|Arg_X|, |Arg_Y|);  V := min(|Arg_X|, |Arg_Y|);
+// sign_X be the sign bit of Arg_X, i.e., sign_X is 0 or 1;
+// s_X    be the sign     of Arg_X, i.e., s_X = (-1)^sign_X;
+//
+// sign_Y be the sign bit of Arg_Y, i.e., sign_Y is 0 or 1;
+// s_Y    be the sign     of Arg_Y, i.e., s_Y = (-1)^sign_Y;
+//
+// swap   be 0  if |Arg_X| >= |Arg_Y|  and 1 otherwise.
+//
+// Then, ATANL(Arg_Y, Arg_X) =
+//
+//       /    arctan(V/U)     \      sign_X = 0 & swap = 0
+//       | pi/2 - arctan(V/U) |      sign_X = 0 & swap = 1
+// s_Y * |                    |
+//       |  pi  - arctan(V/U) |      sign_X = 1 & swap = 0
+//       \ pi/2 + arctan(V/U) /      sign_X = 1 & swap = 1
+//
+//
+// This relationship also suggest that the algorithm's major
+// task is to calculate arctan(V/U) for 0 < V <= U; and the
+// final Result is given by
+//
+//      s_Y * { (P_hi + P_lo) + sigma * arctan(V/U) }
+//
+// where
+//
+//   (P_hi,P_lo) represents M(sign_X,swap)*(pi/2) accurately
+//
+//   M(sign_X,swap) = 0  for sign_X = 0 and swap = 0
+//              1  for swap   = 1
+//              2  for sign_X = 1 and swap = 0
+//
+// and
+//
+//   sigma = { (sign_X  XOR  swap) :  -1.0 : 1.0 }
+//
+//      =  (-1) ^ ( sign_X XOR swap )
+//
+// Both (P_hi,P_lo) and sigma can be stored in a table and fetched
+// using (sign_X,swap) as an index. (P_hi, P_lo) can be stored as a
+// double-precision, and single-precision pair; and sigma can
+// obviously be just a single-precision number.
+//
+// In the algorithm we propose, arctan(V/U) is calculated to high accuracy
+// as A_hi + A_lo. Consequently, the Result ATANL( Arg_Y, Arg_X ) is
+// given by
+//
+//    s_Y*P_hi + s_Y*sigma*A_hi + s_Y*(sigma*A_lo + P_lo)
+//
+// We now discuss the calculation of arctan(V/U) for 0 < V <= U.
+//
+// For (V/U) < 2^(-3), we use a simple polynomial of the form
+//
+//      z + z^3*(P_1 + z^2*(P_2 + z^2*(P_3 + ... + P_8)))
+//
+// where z = V/U.
+//
+// For the sake of accuracy, the first term "z" must approximate V/U to
+// extra precision. For z^3 and higher power, a working precision
+// approximation to V/U suffices. Thus, we obtain:
+//
+//      z_hi + z_lo = V/U  to extra precision and
+//      z           = V/U  to working precision
+//
+// The value arctan(V/U) is delivered as two pieces (A_hi, A_lo)
+//
+//      (A_hi,A_lo) = (z_hi, z^3*(P_1 + ... + P_8) + z_lo).
+//
+//
+// For 2^(-3) <= (V/U) <= 1, we use a table-driven approach.
+// Consider
+//
+//      (V/U) = 2^k * 1.b_1 b_2 .... b_63 b_64 b_65 ....
+//
+// Define
+//
+//       z_hi = 2^k * 1.b_1 b_2 b_3 b_4 1
+//
+// then
+//                                            /                \
+//                                            |  (V/U) - z_hi  |
+
+//      arctan(V/U) = arctan(z_hi) + acrtan| -------------- |
+//                                            | 1 + (V/U)*z_hi |

+//
+//                                            /                \
+//                                            |   V - z_hi*U   |
+

+//                                            |   U + V*z_hi   |
+//                                            \                /
+//
+//                  = arctan(z_hi) + acrtan( V' / U' )
+//
+//
+// where
+//
+//      V' = V - U*z_hi;   U' = U + V*z_hi.
+//
+// Let
+//
+//      w_hi + w_lo  = V'/U' to extra precision and
+//           w       = V'/U' to working precision
+//
+// then we can approximate arctan(V'/U') by
+//
+//      arctan(V'/U') = w_hi + w_lo
+//                     + w^3*(Q_1 + w^2*(Q_2 + w^2*(Q_3 + w^2*Q_4)))
+//
+//                       = w_hi + w_lo + poly
+//
+// Finally, arctan(z_hi) is calculated beforehand and stored in a table
+// as Tbl_hi, Tbl_lo. Thus,
+//
+//      (A_hi, A_lo) = (Tbl_hi, w_hi+(poly+(w_lo+Tbl_lo)))
+//
+// This completes the mathematical description.

+// Overview of operation
+//==============================================================
+// Background
+//
+// Implementation
+//
+// Let y= frcpa(a), where a is the argument
+//
+// cbrt(a)= cbrt(a*y)/cbrt(y) = cbrt(1 - (1-a*y)) * (1/cbrt(y))
+//
+// For all values of y, the 3 possible significands of 1/cbrt(y)
+// are stored in a table (T0) to 64 bits of accuracy. (There are
+// 3 possible significands because the exponent of y modulo 3
+// can be 0, 1, or 2.)
+//
+//
+// * cbrt(1 - (1-a*y)) is approximated by a degree-2 polynomial
+//
+// 1 - (1/3)*r - (1/9)*r^2
+//
+// in r = 1-a*y.
+//
+// The table values are stored for three exponent values and are
+// then multiplied by 2^(e/3) where e is the exponent of the input number.
+// This computation is carried out in parallel with the polynomial
+// evaluation:
+//
+// T= 2^(e/3) * T0

+//
+// Overview of operation
+//==============================================================
+// Background
+//
+// Implementation
+//
+// The result is computed as
+// cbrt(x)= cbrt(1 - (1 - x*y)) * (1/cbrt(y))
+// where y = frcpa(x) = (-1)^sgn_y * 2^(3*k+j) * m_y,
+//       m_y in [1,2),  j in {0,1,2}
+//
+//  cbrt(1 - (1 - x*y)) is approximated by a degree-6 polynomial
+//  in r= 1 - x*y :
+// P = 1 - c_1 r - c_2 * r^2 - c_3 * r^3 - c_4 * r^4 - c_5 * r^5 - c_6 * r^6
+//
+//
+// The values (1/cbrt(y)) are stored as two tables of constants T_hi
+// (double-extended precision) and D (single precision) as follows:
+// T_hi (1 + D)= 1/cbrt(y) to about 80 bits of accuracy
+//
+// The tables are only stored for three exponent values (i.e.
+// only for 2^j * m_y, where j in {0,1,2} and m_y covers the 256
+// possible mantissas for an frcpa result); the index is formed
+// by the 8 leading mantissa bits of x, which is the same index used
+// by the hardware to get frcpa(x).
+//
+// The table values are multiplied by 2^k where e is the exponent of
+// the input number.  This multiplication is carried out in parallel with
+// the polynomial evaluation:
+// T= 2^(k) * T_hi

+// 02/18/02 Large arguments processing routine excluded
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 06/03/02 Insure inexact flag set for large arg result
+// 09/05/02 Work range is widened by reduction strengthen (3 parts of Pi/16)
+// 02/10/03 Reordered header: .section, .global, .proc, .align
+// 08/08/03 Improved performance
+// 10/28/04 Saved sincos_r_sincos to avoid clobber by dynamic loader

+// Overview of operation
+//==============================================================
+//
+// Step 1
+// ======
+// Reduce x to region -1/2*pi/2^k ===== 0 ===== +1/2*pi/2^k  where k=4
+//    divide x by pi/2^k.
+//    Multiply by 2^k/pi.
+//    nfloat = Round result to integer (round-to-nearest)
+//
+// r = x -  nfloat * pi/2^k
+//    Do this as ((((x -  nfloat * HIGH(pi/2^k))) -
+//                        nfloat * LOW(pi/2^k)) -
+//                        nfloat * LOWEST(pi/2^k) for increased accuracy.
+//    pi/2^k is stored as two numbers that when added make pi/2^k.
+//       pi/2^k = HIGH(pi/2^k) + LOW(pi/2^k)
+//    HIGH and LOW parts are rounded to zero values,
+//    and LOWEST is rounded to nearest one.
+//
+// x = (nfloat * pi/2^k) + r
+//    r is small enough that we can use a polynomial approximation
+//    and is referred to as the reduced argument.
+//
+// Step 3
+// ======
+// Take the unreduced part and remove the multiples of 2pi.
+// So nfloat = nfloat (with lower k+1 bits cleared) + lower k+1 bits
+//
+//    nfloat (with lower k+1 bits cleared) is a multiple of 2^(k+1)
+//    N * 2^(k+1)
+//    nfloat * pi/2^k = N * 2^(k+1) * pi/2^k + (lower k+1 bits) * pi/2^k
+//    nfloat * pi/2^k = N * 2 * pi + (lower k+1 bits) * pi/2^k
+//    nfloat * pi/2^k = N2pi + M * pi/2^k
+//
+//
+// Sin(x) = Sin((nfloat * pi/2^k) + r)
+//        = Sin(nfloat * pi/2^k) * Cos(r) + Cos(nfloat * pi/2^k) * Sin(r)
+//
+//          Sin(nfloat * pi/2^k) = Sin(N2pi + Mpi/2^k)
+//                               = Sin(N2pi)Cos(Mpi/2^k) + Cos(N2pi)Sin(Mpi/2^k)
+//                               = Sin(Mpi/2^k)
+//
+//          Cos(nfloat * pi/2^k) = Cos(N2pi + Mpi/2^k)
+//                               = Cos(N2pi)Cos(Mpi/2^k) + Sin(N2pi)Sin(Mpi/2^k)
+//                               = Cos(Mpi/2^k)
+//
+// Sin(x) = Sin(Mpi/2^k) Cos(r) + Cos(Mpi/2^k) Sin(r)
+//
+//
+// Step 4
+// ======
+// 0 <= M < 2^(k+1)
+// There are 2^(k+1) Sin entries in a table.
+// There are 2^(k+1) Cos entries in a table.
+//
+// Get Sin(Mpi/2^k) and Cos(Mpi/2^k) by table lookup.
+//
+//
+// Step 5
+// ======
+// Calculate Cos(r) and Sin(r) by polynomial approximation.
+//
+// Cos(r) = 1 + r^2 q1  + r^4 q2 + r^6 q3 + ... = Series for Cos
+// Sin(r) = r + r^3 p1  + r^5 p2 + r^7 p3 + ... = Series for Sin
+//
+// and the coefficients q1, q2, ... and p1, p2, ... are stored in a table
+//
+//
+// Calculate
+// Sin(x) = Sin(Mpi/2^k) Cos(r) + Cos(Mpi/2^k) Sin(r)
+//
+// as follows
+//
+//    S[m] = Sin(Mpi/2^k) and C[m] = Cos(Mpi/2^k)
+//    rsq = r*r
+//
+//
+//    P = p1 + r^2p2 + r^4p3 + r^6p4
+//    Q = q1 + r^2q2 + r^4q3 + r^6q4
+//
+//       rcub = r * rsq
+//       Sin(r) = r + rcub * P
+//              = r + r^3p1  + r^5p2 + r^7p3 + r^9p4 + ... = Sin(r)
+//
+//            The coefficients are not exactly these values, but almost.
+//
+//            p1 = -1/6  = -1/3!
+//            p2 = 1/120 =  1/5!
+//            p3 = -1/5040 = -1/7!
+//            p4 = 1/362889 = 1/9!
+//
+//       P =  r + rcub * P
+//
+//    Answer = S[m] Cos(r) + [Cm] P
+//
+//       Cos(r) = 1 + rsq Q
+//       Cos(r) = 1 + r^2 Q
+//       Cos(r) = 1 + r^2 (q1 + r^2q2 + r^4q3 + r^6q4)
+//       Cos(r) = 1 + r^2q1 + r^4q2 + r^6q3 + r^8q4 + ...
+//
+//       S[m] Cos(r) = S[m](1 + rsq Q)
+//       S[m] Cos(r) = S[m] + Sm rsq Q
+//       S[m] Cos(r) = S[m] + s_rsq Q
+//       Q         = S[m] + s_rsq Q
+//
+// Then,
+//

+// 08/31/00 Saved 2 cycles in main path, and 9 in other paths.
+// 09/20/00 The updated tables regressed to an old version, so reinstated them
+// 10/18/00 Changed one table entry to ensure symmetry
+// 01/03/01 Improved speed, fixed flag settings for small arguments.
+// 02/18/02 Large arguments processing routine excluded
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 06/03/02 Insure inexact flag set for large arg result
+// 09/05/02 Single precision version is made using double precision one as base
+// 02/10/03 Reordered header: .section, .global, .proc, .align
+// 03/31/05 Reformatted delimiters between data tables

+//
+// Overview of operation
+//==============================================================
+//
+// Step 1
+// ======
+// Reduce x to region -1/2*pi/2^k ===== 0 ===== +1/2*pi/2^k  where k=4
+//    divide x by pi/2^k.
+//    Multiply by 2^k/pi.
+//    nfloat = Round result to integer (round-to-nearest)
+//
+// r = x -  nfloat * pi/2^k
+//    Do this as (x -  nfloat * HIGH(pi/2^k)) - nfloat * LOW(pi/2^k)
+
+//    for increased accuracy.
+//    pi/2^k is stored as two numbers that when added make pi/2^k.
+//       pi/2^k = HIGH(pi/2^k) + LOW(pi/2^k)
+//    HIGH part is rounded to zero, LOW - to nearest
+//
+// x = (nfloat * pi/2^k) + r
+//    r is small enough that we can use a polynomial approximation
+//    and is referred to as the reduced argument.
+//
+// Step 3
+// ======
+// Take the unreduced part and remove the multiples of 2pi.
+// So nfloat = nfloat (with lower k+1 bits cleared) + lower k+1 bits
+//
+//    nfloat (with lower k+1 bits cleared) is a multiple of 2^(k+1)
+//    N * 2^(k+1)
+//    nfloat * pi/2^k = N * 2^(k+1) * pi/2^k + (lower k+1 bits) * pi/2^k
+//    nfloat * pi/2^k = N * 2 * pi + (lower k+1 bits) * pi/2^k
+//    nfloat * pi/2^k = N2pi + M * pi/2^k
+//
+//
+// Sin(x) = Sin((nfloat * pi/2^k) + r)
+//        = Sin(nfloat * pi/2^k) * Cos(r) + Cos(nfloat * pi/2^k) * Sin(r)
+//
+//          Sin(nfloat * pi/2^k) = Sin(N2pi + Mpi/2^k)
+//                               = Sin(N2pi)Cos(Mpi/2^k) + Cos(N2pi)Sin(Mpi/2^k)
+//                               = Sin(Mpi/2^k)
+//
+//          Cos(nfloat * pi/2^k) = Cos(N2pi + Mpi/2^k)
+//                               = Cos(N2pi)Cos(Mpi/2^k) + Sin(N2pi)Sin(Mpi/2^k)
+//                               = Cos(Mpi/2^k)
+//
+// Sin(x) = Sin(Mpi/2^k) Cos(r) + Cos(Mpi/2^k) Sin(r)
+//
+//
+// Step 4
+// ======
+// 0 <= M < 2^(k+1)
+// There are 2^(k+1) Sin entries in a table.
+// There are 2^(k+1) Cos entries in a table.
+//
+// Get Sin(Mpi/2^k) and Cos(Mpi/2^k) by table lookup.
+//
+//
+// Step 5
+// ======
+// Calculate Cos(r) and Sin(r) by polynomial approximation.
+//
+// Cos(r) = 1 + r^2 q1  + r^4 q2  = Series for Cos
+// Sin(r) = r + r^3 p1  + r^5 p2  = Series for Sin
+//
+// and the coefficients q1, q2 and p1, p2 are stored in a table
+//
+//
+// Calculate
+// Sin(x) = Sin(Mpi/2^k) Cos(r) + Cos(Mpi/2^k) Sin(r)
+//
+// as follows
+//
+//    S[m] = Sin(Mpi/2^k) and C[m] = Cos(Mpi/2^k)
+//    rsq = r*r
+//
+//
+//    P = P1 + r^2*P2
+//    Q = Q1 + r^2*Q2
+//
+//       rcub = r * rsq
+//       Sin(r) = r + rcub * P
+//              = r + r^3p1  + r^5p2 = Sin(r)
+//
+//            The coefficients are not exactly these values, but almost.
+//
+//            p1 = -1/6  = -1/3!
+//            p2 = 1/120 =  1/5!
+//            p3 = -1/5040 = -1/7!
+//            p4 = 1/362889 = 1/9!
+//
+//       P =  r + r^3 * P
+//
+//    Answer = S[m] Cos(r) + C[m] P
+//
+//       Cos(r) = 1 + rsq Q
+//       Cos(r) = 1 + r^2 Q
+//       Cos(r) = 1 + r^2 (q1 + r^2q2)
+//       Cos(r) = 1 + r^2q1 + r^4q2
+//
+//       S[m] Cos(r) = S[m](1 + rsq Q)
+//       S[m] Cos(r) = S[m] + S[m] rsq Q
+//       S[m] Cos(r) = S[m] + s_rsq Q
+//       Q         = S[m] + s_rsq Q
+//
+// Then,

+//  Mathematical Description
+//  ========================
+//
+//  The computation of FSIN and FCOS is best handled in one piece of
+//  code. The main reason is that given any argument Arg, computation
+//  of trigonometric functions first calculate N and an approximation
+//  to alpha where
+//
+//  Arg = N pi/2 + alpha, |alpha| <= pi/4.
+//
+//  Since
+//
+//  cosl( Arg ) = sinl( (N+1) pi/2 + alpha ),
+//
+//  therefore, the code for computing sine will produce cosine as long
+//  as 1 is added to N immediately after the argument reduction
+//  process.
+//
+//  Let M = N if sine
+//      N+1 if cosine.
+//
+//  Now, given
+//
+//  Arg = M pi/2  + alpha, |alpha| <= pi/4,
+//
+//  let I = M mod 4, or I be the two lsb of M when M is represented
+//  as 2's complement. I = [i_0 i_1]. Then
+//
+//  sinl( Arg ) = (-1)^i_0  sinl( alpha )        if i_1 = 0,
+//             = (-1)^i_0  cosl( alpha )     if i_1 = 1.
+//
+//  For example:
+//       if M = -1, I = 11
+//         sin ((-pi/2 + alpha) = (-1) cos (alpha)
+//       if M = 0, I = 00
+//         sin (alpha) = sin (alpha)
+//       if M = 1, I = 01
+//         sin (pi/2 + alpha) = cos (alpha)
+//       if M = 2, I = 10
+//         sin (pi + alpha) = (-1) sin (alpha)
+//       if M = 3, I = 11
+//         sin ((3/2)pi + alpha) = (-1) cos (alpha)
+//
+//  The value of alpha is obtained by argument reduction and
+//  represented by two working precision numbers r and c where
+//
+//  alpha =  r  +  c     accurately.
+//
+//  The reduction method is described in a previous write up.
+//  The argument reduction scheme identifies 4 cases. For Cases 2
+//  and 4, because |alpha| is small, sinl(r+c) and cosl(r+c) can be
+//  computed very easily by 2 or 3 terms of the Taylor series
+//  expansion as follows:
+//
+//  Case 2:
+//  -------
+//
+//  sinl(r + c) = r + c - r^3/6        accurately
+//  cosl(r + c) = 1 - 2^(-67)        accurately
+//
+//  Case 4:
+//  -------
+//
+//  sinl(r + c) = r + c - r^3/6 + r^5/120        accurately
+//  cosl(r + c) = 1 - r^2/2 + r^4/24                accurately
+//
+//  The only cases left are Cases 1 and 3 of the argument reduction
+//  procedure. These two cases will be merged since after the
+//  argument is reduced in either cases, we have the reduced argument
+//  represented as r + c and that the magnitude |r + c| is not small
+//  enough to allow the usage of a very short approximation.
+//
+//  The required calculation is either
+//
+//  sinl(r + c)  =  sinl(r)  +  correction,  or
+//  cosl(r + c)  =  cosl(r)  +  correction.
+//
+//  Specifically,
+//
+//        sinl(r + c) = sinl(r) + c sin'(r) + O(c^2)
+//                   = sinl(r) + c cos (r) + O(c^2)
+//                   = sinl(r) + c(1 - r^2/2)  accurately.
+//  Similarly,
+//
+//        cosl(r + c) = cosl(r) - c sinl(r) + O(c^2)
+//                   = cosl(r) - c(r - r^3/6)  accurately.
+//
+//  We therefore concentrate on accurately calculating sinl(r) and
+//  cosl(r) for a working-precision number r, |r| <= pi/4 to within
+//  0.1% or so.
+//
+//  The greatest challenge of this task is that the second terms of
+//  the Taylor series
+//
+//        r - r^3/3! + r^r/5! - ...
+//
+//  and
+//
+//        1 - r^2/2! + r^4/4! - ...
+//
+//  are not very small when |r| is close to pi/4 and the rounding
+//  errors will be a concern if simple polynomial accumulation is
+//  used. When |r| < 2^-3, however, the second terms will be small
+//  enough (6 bits or so of right shift) that a normal Horner
+//  recurrence suffices. Hence there are two cases that we consider
+//  in the accurate computation of sinl(r) and cosl(r), |r| <= pi/4.
+//
+//  Case small_r: |r| < 2^(-3)
+//  --------------------------
+//
+//  Since Arg = M pi/4 + r + c accurately, and M mod 4 is [i_0 i_1],
+//  we have
+//
+//        sinl(Arg) = (-1)^i_0 * sinl(r + c)        if i_1 = 0
+//                 = (-1)^i_0 * cosl(r + c)         if i_1 = 1
+//
+//  can be accurately approximated by
+//
+//  sinl(Arg) = (-1)^i_0 * [sinl(r) + c]        if i_1 = 0
+//           = (-1)^i_0 * [cosl(r) - c*r] if i_1 = 1
+//
+//  because |r| is small and thus the second terms in the correction
+//  are unneccessary.
+//
+//  Finally, sinl(r) and cosl(r) are approximated by polynomials of
+//  moderate lengths.
+//
+//  sinl(r) =  r + S_1 r^3 + S_2 r^5 + ... + S_5 r^11
+//  cosl(r) =  1 + C_1 r^2 + C_2 r^4 + ... + C_5 r^10
+//
+//  We can make use of predicates to selectively calculate
+//  sinl(r) or cosl(r) based on i_1.
+//
+//  Case normal_r: 2^(-3) <= |r| <= pi/4
+//  ------------------------------------
+//
+//  This case is more likely than the previous one if one considers
+//  r to be uniformly distributed in [-pi/4 pi/4]. Again,
+//
+//  sinl(Arg) = (-1)^i_0 * sinl(r + c)        if i_1 = 0
+//           = (-1)^i_0 * cosl(r + c)         if i_1 = 1.
+//
+//  Because |r| is now larger, we need one extra term in the
+//  correction. sinl(Arg) can be accurately approximated by
+//
+//  sinl(Arg) = (-1)^i_0 * [sinl(r) + c(1-r^2/2)]      if i_1 = 0
+//           = (-1)^i_0 * [cosl(r) - c*r*(1 - r^2/6)]    i_1 = 1.
+//
+//  Finally, sinl(r) and cosl(r) are approximated by polynomials of
+//  moderate lengths.
+//
+//        sinl(r) =  r + PP_1_hi r^3 + PP_1_lo r^3 +
+//                      PP_2 r^5 + ... + PP_8 r^17
+//
+//        cosl(r) =  1 + QQ_1 r^2 + QQ_2 r^4 + ... + QQ_8 r^16
+//
+//  where PP_1_hi is only about 16 bits long and QQ_1 is -1/2.
+//  The crux in accurate computation is to calculate
+//
+//  r + PP_1_hi r^3   or  1 + QQ_1 r^2
+//
+//  accurately as two pieces: U_hi and U_lo. The way to achieve this
+//  is to obtain r_hi as a 10 sig. bit number that approximates r to
+//  roughly 8 bits or so of accuracy. (One convenient way is
+//
+//  r_hi := frcpa( frcpa( r ) ).)
+//
+//  This way,
+//
+//        r + PP_1_hi r^3 =  r + PP_1_hi r_hi^3 +
+//                                PP_1_hi (r^3 - r_hi^3)
+//                        =  [r + PP_1_hi r_hi^3]  +
+//                           [PP_1_hi (r - r_hi)
+//                              (r^2 + r_hi r + r_hi^2) ]
+//                        =  U_hi  +  U_lo
+//
+//  Since r_hi is only 10 bit long and PP_1_hi is only 16 bit long,
+//  PP_1_hi * r_hi^3 is only at most 46 bit long and thus computed
+//  exactly. Furthermore, r and PP_1_hi r_hi^3 are of opposite sign
+//  and that there is no more than 8 bit shift off between r and
+//  PP_1_hi * r_hi^3. Hence the sum, U_hi, is representable and thus
+//  calculated without any error. Finally, the fact that
+//
+//        |U_lo| <= 2^(-8) |U_hi|
+//
+//  says that U_hi + U_lo is approximating r + PP_1_hi r^3 to roughly
+//  8 extra bits of accuracy.
+//
+//  Similarly,
+//
+//        1 + QQ_1 r^2  =  [1 + QQ_1 r_hi^2]  +
+//                            [QQ_1 (r - r_hi)(r + r_hi)]
+//                      =  U_hi  +  U_lo.
+//
+//  Summarizing, we calculate r_hi = frcpa( frcpa( r ) ).
+//
+//  If i_1 = 0, then
+//
+//    U_hi := r + PP_1_hi * r_hi^3
+//    U_lo := PP_1_hi * (r - r_hi) * (r^2 + r*r_hi + r_hi^2)
+//    poly := PP_1_lo r^3 + PP_2 r^5 + ... + PP_8 r^17
+//    correction := c * ( 1 + C_1 r^2 )
+//
+//  Else ...i_1 = 1
+//
+//    U_hi := 1 + QQ_1 * r_hi * r_hi
+//    U_lo := QQ_1 * (r - r_hi) * (r + r_hi)
+//    poly := QQ_2 * r^4 + QQ_3 * r^6 + ... + QQ_8 r^16
+//    correction := -c * r * (1 + S_1 * r^2)
+//
+//  End
+//
+//  Finally,
+//
+//        V := poly + ( U_lo + correction )
+//
+//                 /    U_hi  +  V         if i_0 = 0
+//        result := |
+//                 \  (-U_hi) -  V         if i_0 = 1
+//
+//  It is important that in the last step, negation of U_hi is
+//  performed prior to the subtraction which is to be performed in
+//  the user-set rounding mode.

+//  Algorithmic Description
+//  =======================
+//
+//  The argument reduction algorithm is tightly integrated into FSIN
+//  and FCOS which share the same code. The following is complete and
+//  self-contained. The argument reduction description given

+//   * If Arg is +-0, +-inf, NaN, NaT, go to Step 10 for special
+//     handling.
+//   * If |Arg| < 2^24, go to Step 2 for reduction of moderate
+//     arguments. This is the most likely case.
+//   * If |Arg| < 2^63, go to Step 8 for pre-reduction of large

+// Overview of operation
+//==============================================================
+// Background
+//
+//
+// There are 9 paths:
+// 1. x = +/-0.0
+//    Return erf(x) = +/-0.0
+//
+// 2. 0.0 < |x| < 0.5
+//    Return erf(x) = x *Pol9(x^2)
+//
+// 3. For several subranges of 0.5 <= |x| < 5.90625
+//    Return erf(x) = sign(x)*Pol19(y),
+//    where y = (|x|-b)/a, Pol19(y) = A0 + A1*y^1 + A2*y^2 + ... + A19*y^19
+//
+//    For each subrange there is particular set of coefficients.
+//    Below is the list of subranges:
+//    3.1 0.5 <= |x| < 1.0     b = a = 0.5
+//    3.2 1.0 <= |x| < 2.0,    b = a = 1.0
+//    3.3 2.0 <= |x| < 3.25    b = a = 2.0

+// Overview of operation
+//==============================================================
+// 1. 0 <= x <= 28.0
+//
+//    erfc(x)  = P14(z) * exp( -x^2 ), z = x - x(i).
+//
+//    Comment:
+//
+//    Let x(i) = -1.0 + 2^(i/4),i=0,...19. So we have 20 unequal
+//    argument intervals [x(i),x(i+1)] with length ratio q = 2^(1/4).
+//    Values x(i) we have in the table erfc_xb_table.
+//
+//    Let x(i)<= x < x(i+1).
+//    We can find i as exponent of number (x + 1)^4.
+//
+//    Let P14(z) - polynomial approximation of degree 14 for function
+//    erfc(z+x(i)) * exp( (z+x(i))^2) and 0 <= z <= x(i+1)-x(i).
+//    Polynomial coeffitients we have in the table erfc_p_table.
+//
+//    So we can find result for erfc(x) as above.
+//    Algorithm description for exp function see below.
+//
+// 2. -6 <= x < 0
+//
+//      erfc(x)  = 2.0 - erfc(-x)
+//
+// 3. x > 28.0
+//    erfc(x)  ~=~ 0.0
+//
+// 4. x < -6.0
+//    erfc(x)  ~=~ 2.0
+
+// Special values
+//==============================================================
+// erfc(+0)    = 1.0
+// erfc(-0)    = 1.0
+
+// erfc(+qnan) = +qnan
+// erfc(-qnan) = -qnan
+// erfc(+snan) = +qnan
+// erfc(-snan) = -qnan
+
+// erfc(-inf)  = 2.0
+// erfc(+inf)  = +0

+//==============================================================
+// Take double exp(double) from libm_64.
+//
+// Overview of operation
+//==============================================================
+// Take the input x. w is "how many log2/128 in x?"
+//  w = x * 128/log2
+//  n = int(w)
+//  x = n log2/128 + r + delta
+
+//  n = 128M + index_1 + 2^4 index_2
+//  x = M log2 + (log2/128) index_1 + (log2/8) index_2 + r + delta
+
+//  exp(x) = 2^M  2^(index_1/128)  2^(index_2/8) exp(r) exp(delta)
+//       Construct 2^M
+//       Get 2^(index_1/128) from table_1;
+//       Get 2^(index_2/8)   from table_2;
+//       Calculate exp(r) by series
+//          r = x - n (log2/128)_high
+//          delta = - n (log2/128)_low
+//       Calculate exp(delta) as 1 + delta
+//==============================================================
+//  Comment for exp for erfc:
+//
+//  We use quad precision for calculate input argument -x^2 and add
+//  result low bits to value delta in exp.

+//    Comment:
+//
+//    Let x(0)=0, x(i) = 2^(i), i=1,...3, x(4)= 10.06
+//
+//    Let x(i)<= x < x(i+1).
+//    We can find i as exponent of argument x (let i = 0 for 0<= x < 2  )
+//
+//    Let P15(x) - polynomial approximation of degree 15 for function
+//    erfcf(x) * exp( x^2) and x(i) <= x <= x(i+1), i = 0,1,2,3
+//    Polynomial coeffitients we have in the table erfc_p_table.
+//
+//    So we can find result for erfcf(x) as above.
+//    Algorithm description for exp function see below.
+//
+// 2. -4.4 <= x < 0

+//    Comment:
+//
+//    Let x(i) = -1.0 + 2^(i/4),i=0,...27. So we have 28 unequal
+//    argument intervals [x(i),x(i+1)] with length ratio q = 2^(1/4).
+//    Values xc(i) we have in the table erfc_xc_table,xc(i)=x(i)for i = 0
+//    and xc(i)= 0.5*( x(i)+x(i+1) ) for i>0.
+//
+//    Let x(i)<= x < x(i+1).
+//    We can find i as exponent of number (x + 1)^4.
+//
+//    Let P15(z)= a0+ a1*z +..+a15*z^15 - polynomial approximation of degree 15
+//    for function      erfcl(z+xc(i)) * expl( (z+xc(i))^2)* (dx+z+xc(i)) and
+//    -0.5*[x(i+1)-x(i)] <= z <= 0.5*[x(i+1)-x(i)].
+//
+//    Let  Q(z)= (P(z)- S)/S, S = a0, rounded to 16 bits.
+//    Polynomial coeffitients for Q(z) we have in the table erfc_Q_table as
+//    long double values
+//
+//    We use multi precision to calculate input argument -x^2 for expl and
+//    for u = 1/(dx + x).
+//
+//    Algorithm description for expl function see below. In accordance with
+//    denotation of this algorithm we have for expl:
+//
+//    expl(X) ~=~ 2^K*T_1*(1+W_1)*T_2*(1+W_2)*(1+ poly(r)), X = -x^2.

+//
+//    where dy - low bits of x^2 and u, u*du - hi and low bits of 1/(dx + x).
+//
+//    The order of calculations is the next:
+//
+//    1)  M = 2^K*T_1*T_2*S          without rounding error,
+//    2)  W = W_1 + (W_2 + W_1*W_2), where 1+W  ~=~ (1+W_1)(1+W_2),
+//    3)  H = W - dy,                where 1+H  ~=~ (1+W )(1-dy),
+//    4)  R = poly(r)*H + poly(r),
+//    5)  R = H + R              ,   where 1+R  ~=~ (1+H )(1+poly(r)),
+//    6)  G = Q(z)*R + Q(z),
+//    7)  R1 = R + du,               where 1+R1 ~=~ (1+R)(1+du),
+//    8)  G1 = R1 + G,               where 1+G1 ~=~ (1+R1)(1+Q(z)),
+//    9)  V  = G1*M*u,

+//
+// **** High Level Overview ****
+//
+// The method consists of three cases.
+//
+// If           |X| < Tiny  use case exp_tiny;
+// else if  |X| < 2^(-6)    use case exp_small;
+// else     use case exp_regular;
+//
+// Case exp_tiny:
+//
+//   1 + X     can be used to approximate exp(X)
+//   X + X^2/2 can be used to approximate exp(X) - 1
+//
+// Case exp_small:
+//
+//   Here, exp(X) and exp(X) - 1 can all be
+//   approximated by a relatively simple polynomial.
+//
+//   This polynomial resembles the truncated Taylor series
+//
+//  exp(w) = 1 + w + w^2/2! + w^3/3! + ... + w^n/n!
+//
+// Case exp_regular:
+//
+//   Here we use a table lookup method. The basic idea is that in
+//   order to compute exp(X), we accurately decompose X into
+//
+//   X = N * log(2)/(2^12)  + r,    |r| <= log(2)/2^13.
+//
+//   Hence
+//
+//   exp(X) = 2^( N / 2^12 ) * exp(r).
+//
+//   The value 2^( N / 2^12 ) is obtained by simple combinations
+//   of values calculated beforehand and stored in table; exp(r)
+//   is approximated by a short polynomial because |r| is small.
+//
+//   We elaborate this method in 4 steps.
+//
+//   Step 1: Reduction
+//
+//   The value 2^12/log(2) is stored as a double-extended number
+//   L_Inv.
+//
+//   N := round_to_nearest_integer( X * L_Inv )
+//
+//   The value log(2)/2^12 is stored as two numbers L_hi and L_lo so
+//   that r can be computed accurately via
+//
+//   r := (X - N*L_hi) - N*L_lo
+//
+//   We pick L_hi such that N*L_hi is representable in 64 sig. bits
+//   and thus the FMA   X - N*L_hi   is error free. So r is the
+//   1 rounding error from an exact reduction with respect to
+//
+//   L_hi + L_lo.
+//
+//   In particular, L_hi has 30 significant bit and can be stored
+//   as a double-precision number; L_lo has 64 significant bits and
+//   stored as a double-extended number.
+//
+//   Step 2: Approximation
+//
+//   exp(r) - 1 is approximated by a short polynomial of the form
+//
+//   r + A_1 r^2 + A_2 r^3 + A_3 r^4 .
+//
+//   Step 3: Composition from Table Values
+//
+//   The value 2^( N / 2^12 ) can be composed from a couple of tables
+//   of precalculated values. First, express N as three integers
+//   K, M_1, and M_2 as
+//
+//     N  =  K * 2^12  + M_1 * 2^6 + M_2
+//
+//   Where 0 <= M_1, M_2 < 2^6; and K can be positive or negative.
+//   When N is represented in 2's complement, M_2 is simply the 6
+//   lsb's, M_1 is the next 6, and K is simply N shifted right
+//   arithmetically (sign extended) by 12 bits.
+//
+//   Now, 2^( N / 2^12 ) is simply
+//
+//      2^K * 2^( M_1 / 2^6 ) * 2^( M_2 / 2^12 )
+//
+//   Clearly, 2^K needs no tabulation. The other two values are less
+//   trivial because if we store each accurately to more than working
+//   precision, than its product is too expensive to calculate. We
+//   use the following method.
+//
+//   Define two mathematical values, delta_1 and delta_2, implicitly
+//   such that
+//
+//     T_1 = exp( [M_1 log(2)/2^6]  -  delta_1 )
+//     T_2 = exp( [M_2 log(2)/2^12] -  delta_2 )
+//
+//   are representable as 24 significant bits. To illustrate the idea,
+//   we show how we define delta_1:
+//
+//     T_1     := round_to_24_bits( exp( M_1 log(2)/2^6 ) )
+//     delta_1  = (M_1 log(2)/2^6) - log( T_1 )
+//
+//   The last equality means mathematical equality. We then tabulate
+//
+//     W_1 := exp(delta_1) - 1
+//     W_2 := exp(delta_2) - 1
+//
+//   Both in double precision.
+//
+//   From the tabulated values T_1, T_2, W_1, W_2, we compose the values
+//   T and W via
+//
+//     T := T_1 * T_2           ...exactly
+//     W := W_1 + (1 + W_1)*W_2
+//
+//   W approximates exp( delta ) - 1  where delta = delta_1 + delta_2.
+//   The mathematical product of T and (W+1) is an accurate representation
+//   of 2^(M_1/2^6) * 2^(M_2/2^12).
+//
+//   Step 4. Reconstruction
+//
+//   Finally, we can reconstruct exp(X), exp(X) - 1.
+//   Because

+//   **** Algorithm Details ****
+//
+//   A careful algorithm must be used to realize the mathematical ideas
+//   accurately. We describe each of the three cases. We assume SAFE
+//   is preset to be TRUE.
+//
+//   Case exp_tiny:
+//
+//   The important points are to ensure an accurate result under
+//   different rounding directions and a correct setting of the SAFE
+//   flag.
+//
+//   If expm1 is 1, then
+//      SAFE  := False  ...possibility of underflow
+//      Scale := 1.0
+//      Y_hi  := X
+//      Y_lo  := 2^(-17000)
+//   Else
+//      Scale := 1.0
+//      Y_hi  := 1.0
+//      Y_lo  := X  ...for different rounding modes
+//   Endif
+//
+//   Case exp_small:
+//
+//   Here we compute a simple polynomial. To exploit parallelism, we split
+//   the polynomial into several portions.
+//
+//   Let r = X
+//
+//   If exp     ...i.e. exp( argument )
+//

+//      Y_hi    := X
+//      Scale   := 1.0
+//
+//   Endif
+//
+//  Case exp_regular:
+//
+//  The previous description contain enough information except the
+//  computation of poly and the final Y_hi and Y_lo in the case for
+//  exp(X)-1.
+//
+//  The computation of poly for Step 2:
+//
+//   rsq := r*r
+//   poly := r + rsq*(A_1 + r*(A_2 + r*A_3))
+//
+//  For the case exp(X) - 1, we need to incorporate 2^(-K) into
+//  Y_hi and Y_lo at the end of Step 4.
+//
+//   If K > 10 then
+//      Y_lo := Y_lo - 2^(-K)
+//   Else
+//      If K < -10 then
+//   Y_lo := Y_hi + Y_lo

+//
+// Overview of operation
+//==============================================================
+// Background
+//
+//
+// There are 8 paths:
+// 1. x = +/-0.0
+//    Return erff(x) = +/-0.0
+//
+// 2. 0.0 < |x| < 0.125
+//    Return erff(x) = x *Pol3(x^2),
+//    where Pol3(x^2) = C3*x^6 + C2*x^4 + C1*x^2 + C0
+//
+// 3. 0.125 <= |x| < 4.0
+//    Return erff(x) = sign(x)*PolD(x)*PolC(|x|) + sign(x)*PolA(|x|),
+//    where sign(x)*PolD(x) = sign(x)*(|x|^7 + D2*x^6 + D1*|x|^5 + D0*x^4),
+//          PolC(|x|) = B0*x^4 + C3*|x|^3 + C2*|x|^2 + C1*|x| + C0,
+//          PolA(|x|) = A3|x|^3 + A2*x^2 + A1*|x| + A0
+//
+//    Actually range 0.125<=|x|< 4.0 is splitted to 5 subranges.
+//    For each subrange there is particular set of coefficients.
+//    Below is the list of subranges:
+//    3.1 0.125 <= |x| < 0.25
+//    3.2 0.25 <= |x| < 0.5
+//    3.3 0.5 <= |x| < 1.0
+//    3.4 1.0 <= |x| < 2.0
+//    3.5 2.0 <= |x| < 4.0
+//
+// 4. 4.0 <= |x| < +INF
+//    Return erff(x) = sign(x)*(1.0d - 2^(-52))
+//
+// 5. |x| = INF
+//    Return erff(x) = sign(x) * 1.0
+//
+// 6. x = [S,Q]NaN
+//    Return erff(x) = QNaN
+//
+// 7. x is positive denormal
+//    Return erff(x) = C0*x - x^2,
+//    where C0 = 2.0/sqrt(Pi)
+//
+// 8. x is negative denormal
+//    Return erff(x) = C0*x + x^2,
+//    where C0 = 2.0/sqrt(Pi)
+//
+// Registers used
+//==============================================================
+// Floating Point registers used:
+// f8, input
+// f32 -> f59
+
+// General registers used:
+// r32 -> r45, r2, r3
+
+// Predicate registers used:
+// p0, p6 -> p12, p14, p15
+
+// p6           to filter out case when x = [Q,S]NaN or +/-0
+// p7           to filter out case when x = denormal
+// p8           set if |x| >= 0.3125, used also to process denormal input
+// p9           to filter out case when |x| = inf
+// p10          to filter out case when |x| < 0.125
+// p11          to filter out case when 0.125 <= |x| < 4.0
+// p12          to filter out case when |x| >= 4.0
+// p14          set to 1 for positive x
+// p15          set to 1 for negative x

+//
+// Algorithm description
+// ---------------------
+//
+// There are 4 paths:
+//
+// 1. Special path: x = 0, Inf, NaNs, denormal
+//    Return erfl(x) = +/-0.0 for zeros
+//    Return erfl(x) = QNaN for NaNs
+//    Return erfl(x) = sign(x)*1.0 for Inf
+//    Return erfl(x) = (A0H+A0L)*x + x^2, ((A0H+A0L) = 2.0/sqrt(Pi))
+//                                             for denormals
+//
+// 2. [0;1/8] path: 0.0 < |x| < 1/8
+//    Return erfl(x) = x*(A1H+A1L) + x^3*A3 + ... + x^15*A15
+//
+// 3. Main path: 1/8 <= |x| < 6.53
+//    For several ranges of 1/8 <= |x| < 6.53
+//    Return erfl(x) = sign(x)*((A0H+A0L) + y*(A1H+A1L) + y^2*(A2H+A2L) +
+//                                       + y^3*A3 + y^4*A4 + ... + y^25*A25 )
+//    where y = (|x|/a) - b
+//
+//    For each range there is particular set of coefficients.
+//    Below is the list of ranges:
+//    1/8  <= |x| < 1/4     a = 0.125, b = 1.5
+//    1/4  <= |x| < 1/2     a = 0.25,  b = 1.5
+//    1/2  <= |x| < 1.0     a = 0.5,   b = 1.5
+//    1.0  <= |x| < 2.0     a = 1.0,   b = 1.5
+//    2.0  <= |x| < 3.25    a = 2.0,   b = 1.5
+//    3.25 <= |x| < 4.0     a = 2.0,   b = 2.0
+//    4.0  <= |x| < 6.53    a = 4.0,   b = 1.5
+//    ( [3.25;4.0] subrange separated for monotonicity issues resolve )
+//
+// 4. Saturation path: 6.53 <= |x| < +INF
+//    Return erfl(x) = sign(x)*(1.0 - tiny_value)
+//    (tiny_value ~ 1e-1233)
+//
+// Implementation notes
+// --------------------
+//
+// 1. Special path: x = 0, INF, NaNa, denormals
+//
+//    This branch is cut off by one fclass operation.
+//    Then zeros+nans, infinities and denormals processed separately.
+//    For denormals we had to use multiprecision A0 coefficient to reach
+//    necessary accuracy: (A0H+A0L)*x-x^2
+//
+// 2. [0;1/8] path: 0.0 < |x| < 1/8
+//
+//    First coefficient of polynomial we must split to multiprecision too.
+//    Also we can parallelise computations:
+//    (x*(A1H+A1L)) calculated in parallel with "tail" (x^3*A3 + ... + x^15*A15)
+//    Furthermore the second part is factorized using binary tree technique.
+//
+// 3. Main path: 1/8 <= |x| < 6.53
+//
+//    Multiprecision have to be performed only for first few
+//    polynomial iterations (up to 3-rd x degree)
+//    Here we use the same parallelisation way as above:
+//    Split whole polynomial to first, "multiprecision" part, and second,
+//    so called "tail", native precision part.
+//
+//    1) Multiprecision part:
+//    [v1=(A0H+A0L)+y*(A1H+A1L)] + [v2=y^2*((A2H+A2L)+y*A3)]
+//    v1 and v2 terms calculated in parallel
+//
+//    2) Tail part:
+//    v3 = x^4 * ( A4 + x*A5 + ... + x^21*A25 )
+//    v3 is splitted to 2 even parts (10 coefficient in each one).
+//    These 2 parts are also factorized using binary tree technique.
+//
+//    So Multiprecision and Tail parts cost is almost the same
+//    and we have both results ready before final summation.
+//
+// 4. Saturation path: 6.53 <= |x| < +INF
+//
+//    We use formula sign(x)*(1.0 - tiny_value) instead of simple sign(x)*1.0
+//    just to meet IEEE requirements for different rounding modes in this case.
+//

+// History
+//==============================================================
+// 02/02/00 Initial Version
+// 04/04/00 Unwind support added
+// 08/15/00 Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 07/07/01 Improved speed of all paths
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 11/20/02 Improved speed, algorithm based on exp
+// 03/31/05 Reformatted delimiters between data tables
+
+// API
+//==============================================================
+// double expm1(double)
+
+// Overview of operation
+//==============================================================
+// 1. Inputs of Nan, Inf, Zero, NatVal handled with special paths
+//
+// 2. |x| < 2^-60
+//    Result = x, computed by x + x*x to handle appropriate flags and rounding
+//
+// 3. 2^-60 <= |x| < 2^-2
+//    Result determined by 13th order Taylor series polynomial
+//    expm1f(x) = x + Q2*x^2 + ... + Q13*x^13
+//
+// 4. x < -48.0
+//    Here we know result is essentially -1 + eps, where eps only affects
+//    rounded result.  Set I.
+//
+// 5. x >= 709.7827
+//    Result overflows.  Set I, O, and call error support
+//
+// 6. 2^-2 <= x < 709.7827  or  -48.0 <= x < -2^-2
+//    This is the main path.  The algorithm is described below:
+
+// Take the input x. w is "how many log2/128 in x?"
+//  w = x * 128/log2
+//  n = int(w)
+//  x = n log2/128 + r + delta
+
+//  n = 128M + index_1 + 2^4 index_2
+//  x = M log2 + (log2/128) index_1 + (log2/8) index_2 + r + delta
+
+//  exp(x) = 2^M  2^(index_1/128)  2^(index_2/8) exp(r) exp(delta)
+//       Construct 2^M
+//       Get 2^(index_1/128) from table_1;
+//       Get 2^(index_2/8)   from table_2;
+//       Calculate exp(r) by series by 5th order polynomial
+//          r = x - n (log2/128)_high
+//          delta = - n (log2/128)_low
+//       Calculate exp(delta) as 1 + delta
+
+
+// Special values
+//==============================================================
+// expm1(+0)    = +0.0
+// expm1(-0)    = -0.0
+
+// expm1(+qnan) = +qnan
+// expm1(-qnan) = -qnan
+// expm1(+snan) = +qnan
+// expm1(-snan) = -qnan
+
+// expm1(-inf)  = -1.0
+// expm1(+inf)  = +inf
+
+// Overflow and Underflow
+//=======================
+// expm1(x) = largest double normal when
+//     x = 709.7827 = 40862e42fefa39ef
+//
+// Underflow is handled as described in case 2 above.

+// Overview of operation
+//*********************************************************************
+// 1. Inputs of Nan, Inf, Zero, NatVal handled with special paths
+//
+// 2. |x| < 2^-40
+//    Result = x, computed by x + x*x to handle appropriate flags and rounding
+//
+// 3. 2^-40 <= |x| < 2^-2
+//    Result determined by 8th order Taylor series polynomial
+//    expm1f(x) = x + A2*x^2 + ... + A8*x^8
+//
+// 4. x < -24.0
+//    Here we know result is essentially -1 + eps, where eps only affects
+//    rounded result.  Set I.
+//
+// 5. x >= 88.7228
+//    Result overflows.  Set I, O, and call error support
+//
+// 6. 2^-2 <= x < 88.7228  or  -24.0 <= x < -2^-2
+//    This is the main path.  The algorithm is described below:
+
+// Take the input x. w is "how many log2/128 in x?"
+//  w = x * 64/log2
+//  NJ = int(w)
+//  x = NJ*log2/64 + R
+
+//  NJ = 64*n + j
+//  x = n*log2 + (log2/64)*j + R
+//
+//  So, exp(x) = 2^n * 2^(j/64)* exp(R)
+//
+//  T =  2^n * 2^(j/64)
+//       Construct 2^n
+//       Get 2^(j/64) table
+//           actually all the entries of 2^(j/64) table are stored in DP and
+//           with exponent bits set to 0 -> multiplication on 2^n can be
+//           performed by doing logical "or" operation with bits presenting 2^n
+
+//  exp(R) = 1 + (exp(R) - 1)
+//  P = exp(R) - 1 approximated by Taylor series of 3rd degree
+//      P = A3*R^3 + A2*R^2 + R, A3 = 1/6, A2 = 1/2
+//
+
+//  The final result is reconstructed as follows
+//  expm1f(x) = T*P + (T - 1.0)
+
+// Special values
+//*********************************************************************
+// expm1f(+0)    = +0.0
+// expm1f(-0)    = -0.0
+
+// expm1f(+qnan) = +qnan
+// expm1f(-qnan) = -qnan
+// expm1f(+snan) = +qnan
+// expm1f(-snan) = -qnan

+// expm1f(-inf)  = -1.0
+// expm1f(+inf)  = +inf
+
+// Overflow and Underflow
+//*********************************************************************
+// expm1f(x) = largest single normal when
+//     x = 88.7228 = 0x42b17217

+// appropriately.  Note that SAFE not set (false) does not mean

+// guarantees the opposite.
+//
+// **** High Level Overview ****
+//
+// The method consists of three cases.
+//
+// If           |X| < Tiny	use case exp_tiny;
+// else if	|X| < 2^(-m)	use case exp_small; m=12 for exp, m=7 for expm1
+// else		use case exp_regular;
+//
+// Case exp_tiny:
+//
+//   1 + X     can be used to approximate exp(X)
+//   X + X^2/2 can be used to approximate exp(X) - 1
+//
+// Case exp_small:
+//
+//   Here, exp(X) and exp(X) - 1 can all be
+//   approximated by a relatively simple polynomial.
+//
+//   This polynomial resembles the truncated Taylor series
+//
+//	exp(w) = 1 + w + w^2/2! + w^3/3! + ... + w^n/n!
+//
+// Case exp_regular:
+//
+//   Here we use a table lookup method. The basic idea is that in
+//   order to compute exp(X), we accurately decompose X into
+//
+//   X = N * log(2)/(2^12)  + r,	|r| <= log(2)/2^13.
+//
+//   Hence
+//
+//   exp(X) = 2^( N / 2^12 ) * exp(r).
+//
+//   The value 2^( N / 2^12 ) is obtained by simple combinations
+//   of values calculated beforehand and stored in table; exp(r)
+//   is approximated by a short polynomial because |r| is small.
+//
+//   We elaborate this method in 4 steps.
+//
+//   Step 1: Reduction
+//
+//   The value 2^12/log(2) is stored as a double-extended number
+//   L_Inv.
+//
+//   N := round_to_nearest_integer( X * L_Inv )
+//
+//   The value log(2)/2^12 is stored as two numbers L_hi and L_lo so
+//   that r can be computed accurately via
+//
+//   r := (X - N*L_hi) - N*L_lo
+//
+//   We pick L_hi such that N*L_hi is representable in 64 sig. bits
+//   and thus the FMA   X - N*L_hi   is error free. So r is the
+//   1 rounding error from an exact reduction with respect to
+//
+//   L_hi + L_lo.
+//
+//   In particular, L_hi has 30 significant bit and can be stored
+//   as a double-precision number; L_lo has 64 significant bits and
+//   stored as a double-extended number.
+//
+//   Step 2: Approximation
+//
+//   exp(r) - 1 is approximated by a short polynomial of the form
+//
+//   r + A_1 r^2 + A_2 r^3 + A_3 r^4 .
+//
+//   Step 3: Composition from Table Values
+//
+//   The value 2^( N / 2^12 ) can be composed from a couple of tables
+//   of precalculated values. First, express N as three integers
+//   K, M_1, and M_2 as
+//
+//     N  =  K * 2^12  + M_1 * 2^6 + M_2
+//
+//   Where 0 <= M_1, M_2 < 2^6; and K can be positive or negative.
+//   When N is represented in 2's complement, M_2 is simply the 6
+//   lsb's, M_1 is the next 6, and K is simply N shifted right
+//   arithmetically (sign extended) by 12 bits.
+//
+//   Now, 2^( N / 2^12 ) is simply
+//
+//      2^K * 2^( M_1 / 2^6 ) * 2^( M_2 / 2^12 )
+//
+//   Clearly, 2^K needs no tabulation. The other two values are less
+//   trivial because if we store each accurately to more than working
+//   precision, than its product is too expensive to calculate. We
+//   use the following method.
+//
+//   Define two mathematical values, delta_1 and delta_2, implicitly
+//   such that
+//
+//     T_1 = exp( [M_1 log(2)/2^6]  -  delta_1 )
+//     T_2 = exp( [M_2 log(2)/2^12] -  delta_2 )
+//
+//   are representable as 24 significant bits. To illustrate the idea,
+//   we show how we define delta_1:
+//
+//     T_1     := round_to_24_bits( exp( M_1 log(2)/2^6 ) )
+//     delta_1  = (M_1 log(2)/2^6) - log( T_1 )
+//
+//   The last equality means mathematical equality. We then tabulate
+//
+//     W_1 := exp(delta_1) - 1
+//     W_2 := exp(delta_2) - 1
+//
+//   Both in double precision.
+//
+//   From the tabulated values T_1, T_2, W_1, W_2, we compose the values
+//   T and W via
+//
+//     T := T_1 * T_2			...exactly
+//     W := W_1 + (1 + W_1)*W_2
+//
+//   W approximates exp( delta ) - 1  where delta = delta_1 + delta_2.
+//   The mathematical product of T and (W+1) is an accurate representation
+//   of 2^(M_1/2^6) * 2^(M_2/2^12).
+//
+//   Step 4. Reconstruction
+//
+//   Finally, we can reconstruct exp(X), exp(X) - 1.
+//   Because
+//
+//	X = K * log(2) + (M_1*log(2)/2^6  - delta_1)
+//		       + (M_2*log(2)/2^12 - delta_2)
+//		       + delta_1 + delta_2 + r 		...accurately
+//   We have
+//
+//	exp(X) ~=~ 2^K * ( T + T*[exp(delta_1+delta_2+r) - 1] )
+//	       ~=~ 2^K * ( T + T*[exp(delta + r) - 1]         )
+//	       ~=~ 2^K * ( T + T*[(exp(delta)-1)
+//				 + exp(delta)*(exp(r)-1)]   )
+//             ~=~ 2^K * ( T + T*( W + (1+W)*poly(r) ) )
+//             ~=~ 2^K * ( Y_hi  +  Y_lo )
+//
+//   where Y_hi = T  and Y_lo = T*(W + (1+W)*poly(r))
+//
+//   For exp(X)-1, we have
+//
+//	exp(X)-1 ~=~ 2^K * ( Y_hi + Y_lo ) - 1
+//		 ~=~ 2^K * ( Y_hi + Y_lo - 2^(-K) )
+//
+//   and we combine Y_hi + Y_lo - 2^(-N)  into the form of two
+//   numbers  Y_hi + Y_lo carefully.
+//
+//   **** Algorithm Details ****
+//
+//   A careful algorithm must be used to realize the mathematical ideas
+//   accurately. We describe each of the three cases. We assume SAFE
+//   is preset to be TRUE.
+//
+//   Case exp_tiny:
+//
+//   The important points are to ensure an accurate result under
+//   different rounding directions and a correct setting of the SAFE
+//   flag.
+//
+//   If expm1 is 1, then
+//      SAFE  := False	...possibility of underflow
+//      Scale := 1.0

+//   Else
+//      Scale := 1.0
+//      Y_hi  := 1.0
+//      Y_lo  := X	...for different rounding modes
+//   Endif
+//
+//   Case exp_small:
+//
+//   Here we compute a simple polynomial. To exploit parallelism, we split
+//   the polynomial into several portions.
+//
+//   Let r = X
+//
+//   If exp 	...i.e. exp( argument )

+//      Y_lo    := rsq*(poly_hi +  rsq*poly_lo)
+//      Y_hi    := X
+//      Scale   := 1.0
+//
+//   Endif
+//
+//  Case exp_regular:
+//
+//  The previous description contain enough information except the
+//  computation of poly and the final Y_hi and Y_lo in the case for
+//  exp(X)-1.
+//
+//  The computation of poly for Step 2:
+//
+//   rsq := r*r
+//   poly := r + rsq*(A_1 + r*(A_2 + r*A_3))
+//
+//  For the case exp(X) - 1, we need to incorporate 2^(-K) into
+//  Y_hi and Y_lo at the end of Step 4.
+//
+//   If K > 10 then
+//      Y_lo := Y_lo - 2^(-K)
+//   Else
+//      If K < -10 then

+// History
+//==============================================================
+// 02/03/00 Initial version
+// 05/26/00 Fix bug when x a double-extended denormal;
+//          if x=0 call error routine, per C9X
+// 08/15/00 Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 01/20/01 Fixed result for x=0, corrected error tag value.
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 01/20/03 Improved performance
+//
+// API
+//==============================================================
+// int ilogb( double x );
+//
+// Overview of operation
+//==============================================================
+// The ilogb function extracts the exponent of x as an integer
+// and returns it in r8
+//
+// ilogb is similar to logb but differs in the following ways:
+//         +-inf
+//            ilogb: returns INT_MAX
+//             logb: returns +inf
+//         Nan  returns FP_LOGBNAN (which is either INT_MAX or INT_MIN)
+//            ilogb: returns INT_MAX (7fffffff)
+//             logb: returns QNAN (quietized SNAN)
+//         0    returns FP_ILOGB0 (which is either INT_MIN or -INT_MAX)
+//            ilogb: returns -INT_MAX (80000001)
+//             logb: returns -inf, raises the divide-by-zero exception,
+//                   and calls libm_error_support to set domain error
+//
+// Registers used
+//==============================================================
+// general registers used:
+// r26 -> r39
+// r36 -> r39 used as parameters to error path
+//
+// predicate registers used:
+// p6 -> p10

+// History
+//==============================================================
+// 02/03/00 Initial version
+// 05/26/00 Fix bug when x a double-extended denormal;
+//          if x=0 call error routine, per C9X
+// 08/15/00 Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 01/20/01 Fixed result for x=0
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 01/20/03 Improved performance
+//
+// API
+//==============================================================
+// int ilogbf( float x );
+//
+// Overview of operation
+//==============================================================
+// The ilogbf function extracts the exponent of x as an integer
+// and returns it in r8
+//
+// ilogbf is similar to logbf but differs in the following ways:
+//         +-inf
+//            ilogbf: returns INT_MAX
+//             logbf: returns +inf
+//         Nan  returns FP_LOGBNAN (which is either INT_MAX or INT_MIN)
+//            ilogbf: returns INT_MAX (7fffffff)
+//             logbf: returns QNAN (quietized SNAN)
+//         0    returns FP_ILOGB0 (which is either INT_MIN or -INT_MAX)
+//            ilogbf: returns -INT_MAX (80000001)
+//             logbf: returns -inf, raises the divide-by-zero exception,
+//                   and calls libm_error_support to set domain error
+//
+// Registers used
+//==============================================================
+// general registers used:
+// r26 -> r39
+// r36 -> r39 used as parameters to error path
+//
+// predicate registers used:
+// p6 -> p10
+// floating-point registers used:
+// f9, f10, f11
+// f8, input

+// 02/10/03 Reordered header: .section, .global, .proc, .align
+// 08/04/03 Improved performance

+// log1p(x) = log(x+1)
+//
+// Overview of operation
+//==============================================================
+// Background
+// ----------
+//
+// This algorithm is based on fact that
+// log1p(x) = log(1+x) and
+// log(a b) = log(a) + log(b).
+// In our case we have 1+x = 2^N f, where 1 <= f < 2.
+// So
+//   log(1+x) = log(2^N f) = log(2^N) + log(f) = n*log(2) + log(f)
+//
+// To calculate log(f) we do following
+//   log(f) = log(f * frcpa(f) / frcpa(f)) =
+//          = log(f * frcpa(f)) + log(1/frcpa(f))
+//
+// According to definition of IA-64's frcpa instruction it's a
+// floating point that approximates 1/f using a lookup on the
+// top of 8 bits of the input number's + 1 significand with relative
+// error < 2^(-8.886). So we have following
+//
+// |(1/f - frcpa(f)) / (1/f))| = |1 - f*frcpa(f)| < 1/256
+//
+// and
+//
+// log(f) = log(f * frcpa(f)) + log(1/frcpa(f)) =
+//        = log(1 + r) + T
+//
+// The first value can be computed by polynomial P(r) approximating
+// log(1 + r) on |r| < 1/256 and the second is precomputed tabular
+// value defined by top 8 bit of f.
+//
+// Finally we have that  log(1+x) ~ (N*log(2) + T) + P(r)
+//
+// Note that if input argument is close to 0.0 (in our case it means
+// that |x| < 1/256) we can use just polynomial approximation
+// because 1+x = 2^0 * f = f = 1 + r and
+// log(1+x) = log(1 + r) ~ P(r)
+//
+//
+// Implementation
+// --------------
+//
+// 1. |x| >= 2^(-8), and x > -1
+//   InvX = frcpa(x+1)
+//   r = InvX*(x+1) - 1
+//   P(r) = r*((r*A3 - A2) + r^4*((A4 + r*A5) + r^2*(A6 + r*A7)),
+//   all coefficients are calcutated in quad and rounded to double
+//   precision. A7,A6,A5,A4 are stored in memory whereas A3 and A2
+//   created with setf.
+//
+//   N = float(n) where n is true unbiased exponent of x
+//
+//   T is tabular value of log(1/frcpa(x)) calculated in quad precision
+//   and represented by two floating-point numbers 64-bit Thi and 32-bit Tlo.
+//   To load Thi,Tlo we get bits from 55 to 62 of register format significand
+//   as index and calculate two addresses
+//     ad_Thi = Thi_table_base_addr + 8 * index
+//     ad_Tlo = Tlo_table_base_addr + 4 * index
+//
+//   L1 (log(2)) is calculated in quad
+//   precision and represented by two floating-point 64-bit numbers L1hi,L1lo
+//   stored in memory.
+//
+//   And final result = ((L1hi*N + Thi) + (N*L1lo + Tlo)) + P(r)
+//
+//
+// 2. 2^(-80) <= |x| < 2^(-8)
+//   r = x
+//   P(r) = r*((r*A3 - A2) + r^4*((A4 + r*A5) + r^2*(A6 + r*A7)),
+//   A7,A6,A5,A4,A3,A2 are the same as in case |x| >= 1/256
+//
+//   And final results
+//     log(1+x)   = P(r)
+//
+// 3. 0 < |x| < 2^(-80)
+//   Although log1p(x) is basically x, we would like to preserve the inexactness
+//   nature as well as consistent behavior under different rounding modes.
+//   We can do this by computing the result as
+//
+//     log1p(x) = x - x*x
+//
+//
+//    Note: NaT, any NaNs, +/-INF, +/-0, negatives and unnormalized numbers are
+//          filtered and processed on special branches.

+// float log1pf(float)
+//
+// log1p(x) = log(x+1)
+//
+// Overview of operation
+//==============================================================
+// Background
+// ----------
+//
+// This algorithm is based on fact that
+// log1p(x) = log(1+x) and
+// log(a b) = log(a) + log(b).
+// In our case we have 1+x = 2^N f, where 1 <= f < 2.
+// So
+//   log(1+x) = log(2^N f) = log(2^N) + log(f) = n*log(2) + log(f)
+//
+// To calculate log(f) we do following
+//   log(f) = log(f * frcpa(f) / frcpa(f)) =
+//          = log(f * frcpa(f)) + log(1/frcpa(f))
+//
+// According to definition of IA-64's frcpa instruction it's a
+// floating point that approximates 1/f using a lookup on the
+// top of 8 bits of the input number's + 1 significand with relative
+// error < 2^(-8.886). So we have following
+//
+// |(1/f - frcpa(f)) / (1/f))| = |1 - f*frcpa(f)| < 1/256
+//
+// and
+//
+// log(f) = log(f * frcpa(f)) + log(1/frcpa(f)) =
+//        = log(1 + r) + T
+//
+// The first value can be computed by polynomial P(r) approximating
+// log(1 + r) on |r| < 1/256 and the second is precomputed tabular
+// value defined by top 8 bit of f.
+//
+// Finally we have that  log(1+x) ~ (N*log(2) + T) + P(r)
+//
+// Note that if input argument is close to 0.0 (in our case it means
+// that |x| < 1/256) we can use just polynomial approximation
+// because 1+x = 2^0 * f = f = 1 + r and
+// log(1+x) = log(1 + r) ~ P(r)
+//
+//
+// Implementation
+// --------------
+//
+// 1. |x| >= 2^(-8), and x > -1
+//   InvX = frcpa(x+1)
+//   r = InvX*(x+1) - 1
+//   P(r) = r*((1 - A2*4) + r^2*(A3 - A4*r)) = r*P2(r),
+//   A4,A3,A2 are created with setf instruction.
+//   We use Taylor series and so A4 = 1/4, A3 = 1/3,
+//   A2 = 1/2 rounded to double.
+//
+//   N = float(n) where n is true unbiased exponent of x
+//
+//   T is tabular value of log(1/frcpa(x)) calculated in quad precision
+//   and rounded to double.  To load T we get bits from 55 to 62 of register
+//   format significand as index and calculate address
+//     ad_T = table_base_addr + 8 * index
+//
+//   L1 (log(2)) is calculated in quad precision and rounded to double;
+//   it's created with setf
+//
+//   And final result = P2(r)*r + (T + N*L1)
+//
+//
+// 2. 2^(-40) <= |x| < 2^(-8)
+//   r = x
+//   P(r) = r*((1 - A2*4) + r^2*(A3 - A4*r)) = r*P2(r),
+//   A4,A3,A2 are the same as in case |x| >= 1/256
+//
+//   And final result = P2(r)*r
+//
+// 3. 0 < |x| < 2^(-40)
+//   Although log1p(x) is basically x, we would like to preserve the inexactness
+//   nature as well as consistent behavior under different rounding modes.
+//   We can do this by computing the result as
+//
+//     log1p(x) = x - x*x
+//
+//
+//    Note: NaT, any NaNs, +/-INF, +/-0, negatives and unnormalized numbers are
+//          filtered and processed on special branches.
+//
+
+//
+// Special values

+// Overview
+//
+// The method consists of three cases.
+//
+// If      |X| < 2^(-80)	use case log1p_small;
+// else    |X| < 2^(-7)	        use case log_near1;
+// else      			use case log_regular;
+//
+// Case log1p_small:
+//
+//   log1pl( X ) = logl( X+1 ) can be approximated by X
+//
+// Case log_near1:
+//
+//   log1pl( X ) = log( X+1 ) can be approximated by a simple polynomial
+//   in W = X. This polynomial resembles the truncated Taylor
+//   series W - W^/2 + W^3/3 - ...
+//
+// Case log_regular:
+//
+//   Here we use a table lookup method. The basic idea is that in
+//   order to compute logl(Arg) = log1pl (Arg-1) for an argument Arg in [1,2),
+//   we construct a value G such that G*Arg is close to 1 and that
+//   logl(1/G) is obtainable easily from a table of values calculated
+//   beforehand. Thus
+//
+//      logl(Arg) = logl(1/G) + logl(G*Arg)
+//      	 = logl(1/G) + logl(1 + (G*Arg - 1))
+//
+//   Because |G*Arg - 1| is small, the second term on the right hand
+//   side can be approximated by a short polynomial. We elaborate
+//   this method in four steps.
+//
+//   Step 0: Initialization
+//
+//   We need to calculate logl( X+1 ). Obtain N, S_hi such that
+//
+//      X+1 = 2^N * ( S_hi + S_lo )   exactly
+//
+//   where S_hi in [1,2) and S_lo is a correction to S_hi in the sense
+//   that |S_lo| <= ulp(S_hi).
+//
+//   Step 1: Argument Reduction
+//
+//   Based on S_hi, obtain G_1, G_2, G_3 from a table and calculate
+//
+//      G := G_1 * G_2 * G_3
+//      r := (G * S_hi - 1) + G * S_lo
+//
+//   These G_j's have the property that the product is exactly
+//   representable and that |r| < 2^(-12) as a result.
+//
+//   Step 2: Approximation
+//
+//
+//   logl(1 + r) is approximated by a short polynomial poly(r).
+//
+//   Step 3: Reconstruction
+//
+//
+//   Finally, log1pl( X ) = logl( X+1 ) is given by
+//
+//   logl( X+1 )   =   logl( 2^N * (S_hi + S_lo) )
+//                 ~=~  N*logl(2) + logl(1/G) + logl(1 + r)
+//                 ~=~  N*logl(2) + logl(1/G) + poly(r).
+//
+// **** Algorithm ****
+//
+// Case log1p_small:
+//
+// Although log1pl(X) is basically X, we would like to preserve the inexactness
+// nature as well as consistent behavior under different rounding modes.
+// We can do this by computing the result as
+//
+//     log1pl(X) = X - X*X
+//
+//
+// Case log_near1:
+//
+// Here we compute a simple polynomial. To exploit parallelism, we split
+// the polynomial into two portions.
+//
+//       W := X
+//       Wsq := W * W
+//       W4  := Wsq*Wsq
+//       W6  := W4*Wsq
+//       Y_hi := W + Wsq*(P_1 + W*(P_2 + W*(P_3 + W*P_4))
+//       Y_lo := W6*(P_5 + W*(P_6 + W*(P_7 + W*P_8)))
+//
+// Case log_regular:
+//
+// We present the algorithm in four steps.
+//
+//   Step 0. Initialization
+//   ----------------------
+//
+//   Z := X + 1
+//   N := unbaised exponent of Z
+//   S_hi := 2^(-N) * Z
+//   S_lo := 2^(-N) * { (max(X,1)-Z) + min(X,1) }
+//
+//   Step 1. Argument Reduction
+//   --------------------------
+//
+//   Let
+//
+//      Z = 2^N * S_hi = 2^N * 1.d_1 d_2 d_3 ... d_63
+//
+//   We obtain G_1, G_2, G_3 by the following steps.
+//
+//
+//      Define		X_0 := 1.d_1 d_2 ... d_14. This is extracted
+//      		from S_hi.
+//
+//      Define		A_1 := 1.d_1 d_2 d_3 d_4. This is X_0 truncated
+//      		to lsb = 2^(-4).
+//
+//      Define		index_1 := [ d_1 d_2 d_3 d_4 ].
+//
+//      Fetch 		Z_1 := (1/A_1) rounded UP in fixed point with
+//      fixed point	lsb = 2^(-15).
+//      		Z_1 looks like z_0.z_1 z_2 ... z_15
+//      	        Note that the fetching is done using index_1.
+//      		A_1 is actually not needed in the implementation
+//      		and is used here only to explain how is the value
+//      		Z_1 defined.
+//
+//      Fetch		G_1 := (1/A_1) truncated to 21 sig. bits.
+//      floating pt.	Again, fetching is done using index_1. A_1
+//      		explains how G_1 is defined.
+//
+//      Calculate	X_1 := X_0 * Z_1 truncated to lsb = 2^(-14)
+//      		     = 1.0 0 0 0 d_5 ... d_14
+//      		This is accomplised by integer multiplication.
+//      		It is proved that X_1 indeed always begin
+//      		with 1.0000 in fixed point.
+//
+//
+//      Define		A_2 := 1.0 0 0 0 d_5 d_6 d_7 d_8. This is X_1
+//      		truncated to lsb = 2^(-8). Similar to A_1,
+//      		A_2 is not needed in actual implementation. It
+//      		helps explain how some of the values are defined.
+//
+//      Define		index_2 := [ d_5 d_6 d_7 d_8 ].
+//
+//      Fetch 		Z_2 := (1/A_2) rounded UP in fixed point with
+//      fixed point	lsb = 2^(-15). Fetch done using index_2.
+//      		Z_2 looks like z_0.z_1 z_2 ... z_15
+//
+//      Fetch		G_2 := (1/A_2) truncated to 21 sig. bits.

+//      		     = 1.0 0 0 0 0 0 0 0 d_9 d_10 ... d_14
+//      		This is accomplised by integer multiplication.
+//      		It is proved that X_2 indeed always begin
+//      		with 1.00000000 in fixed point.
+//
+//
+//      Define		A_3 := 1.0 0 0 0 0 0 0 0 d_9 d_10 d_11 d_12 d_13 1.
+//      		This is 2^(-14) + X_2 truncated to lsb = 2^(-13).
+//
+//      Define		index_3 := [ d_9 d_10 d_11 d_12 d_13 ].
+//
+//      Fetch		G_3 := (1/A_3) truncated to 21 sig. bits.
+//      floating pt.	Fetch is done using index_3.
+//
+//      Compute		G := G_1 * G_2 * G_3.

+//      This is done exactly since each of G_j only has 21 sig. bits.
+//
+//      Compute
+//
+//      	r := (G*S_hi - 1) + G*S_lo using 2 FMA operations.
+//
+//      Thus r approximates G*(S_hi + S_lo) - 1 to within a couple of
+//      rounding errors.
+//
+//
+//  Step 2. Approximation
+//  ---------------------
+//
+//   This step computes an approximation to logl( 1 + r ) where r is the
+//   reduced argument just obtained. It is proved that |r| <= 1.9*2^(-13);
+//   thus logl(1+r) can be approximated by a short polynomial:
+//
+//      logl(1+r) ~=~ poly = r + Q1 r^2 + ... + Q4 r^5
+//
+//
+//  Step 3. Reconstruction
+//  ----------------------
+//
+//   This step computes the desired result of logl(X+1):
+//
+//      logl(X+1) =   logl( 2^N * (S_hi + S_lo) )
+//      	  =   N*logl(2) + logl( S_hi + S_lo) )
+//      	  =   N*logl(2) + logl(1/G) +
+//      	      logl(1 + G * ( S_hi + S_lo ) - 1 )
+//
+//   logl(2), logl(1/G_j) are stored as pairs of (single,double) numbers:
+//   log2_hi, log2_lo, log1byGj_hi, log1byGj_lo. The high parts are
+//   single-precision numbers and the low parts are double precision
+//   numbers. These have the property that
+//
+//      N*log2_hi + SUM ( log1byGj_hi )
+//
+//   is computable exactly in double-extended precision (64 sig. bits).
+//   Finally
+//
+//      Y_hi := N*log2_hi + SUM ( log1byGj_hi )
+//      Y_lo := poly_hi + [ poly_lo +
+//              ( SUM ( log1byGj_lo ) + N*log2_lo ) ]

+// Overview of operation
+//==============================================================
+// The logb function extracts the exponent of x as an integer in
+// floating-point format.
+// logb computes log2 of x as a double
+//
+// logb is similar to ilogb but differs in the  following ways:
+//         +-inf
+//            ilogb: returns INT_MAX
+//             logb: returns +inf
+//         Nan  returns FP_LOGBNAN (which is either INT_MAX or INT_MIN)
+//            ilogb: returns INT_MAX (7fffffff)
+//             logb: returns QNAN (quietized SNAN)
+//         0    returns FP_ILOGB0 (which is either INT_MIN or -INT_MAX)
+//            ilogb: returns -INT_MAX (80000001)
+//             logb: returns -inf, raises the divide-by-zero exception,

+// long double logbl( long double x );
+//
+// Overview of operation
+//==============================================================
+// The logbl function extracts the exponent of x as an integer in
+// floating-point format.
+// logbl computes log2 of x as a long double
+//
+// logbl is similar to ilogbl but differs in the following ways:
+//         +-inf
+//            ilogbl: returns INT_MAX
+//             logbl: returns +inf
+//         Nan  returns FP_LOGBNAN (which is either INT_MAX or INT_MIN)
+//            ilogbl: returns INT_MAX (7fffffff)
+//             logbl: returns QNAN (quietized SNAN)
+//         0    returns FP_ILOGB0 (which is either INT_MIN or -INT_MAX)
+//            ilogbl: returns -INT_MAX (80000001)
+//             logbl: returns -inf, raises the divide-by-zero exception,
+//                   and calls libm_error_support to set domain error
+//

+//==============================================================
+// 02/02/00 Initial version
+// 03/03/00 Modified to conform to C9X, and improve speed of main path
+// 03/14/00 Fixed case where x is a power of 2, and x > y, improved speed
+// 04/04/00 Unwind support added
+// 05/12/00 Fixed erroneous denormal flag setting for exponent change cases 1,3
+// 08/15/00 Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 09/09/00 Updated fcmp so that qnans do not raise invalid
+// 12/15/00 Corrected behavior when both args are zero to conform to C99, and
+//          fixed flag settings for several cases
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 02/10/03 Reordered header: .section, .global, .proc, .align

+// 03/14/00 Fixed case where x is a power of 2, and x > y, improved speed
+// 04/04/00 Unwind support added
+// 05/12/00 Fixed erroneous denormal flag setting for exponent change cases 1,3
+// 08/15/00 Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 09/09/00 Updated fcmp so that qnans do not raise invalid.
+// 12/15/00 Fixed case of smallest long double normal to largest denormal,
+//          now adhere to C99 for two zero args, and fixed flag settings
+//          for several cases
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 02/10/03 Reordered header: .section, .global, .proc, .align

+// History
+//==============================================================
+// 02/02/00 Initial version
+// 04/04/00 Unwind support added
+// 12/27/00 Improved speed
+// 02/21/01 Updated to call tanl
+// 05/30/02 Added cot
+// 02/10/03 Reordered header: .section, .global, .proc, .align
+//
+// API
+//==============================================================
+// double tan(double x);
+// double cot(double x);
+//
+// Overview of operation
+//==============================================================
+// If the input value in radians is |x| >= 1.xxxxx 2^10 call the
+// older slower version.
+//
+// The new algorithm is used when |x| <= 1.xxxxx 2^9.
+//
+// Represent the input X as Nfloat * pi/2 + r
+//    where r can be negative and |r| <= pi/4
+//
+//     tan_W  = x * 2/pi
+//     Nfloat = round_int(tan_W)
+//
+//     tan_r  = x - Nfloat * (pi/2)_hi
+//  a) tan_r  = tan_r - Nfloat * (pi/2)_lo (for tan)
+//  b) tan_r  = Nfloat * (pi/2)_lo - tan_r (for cot)
+//
+// We have two paths: p8, when Nfloat is even and p9. when Nfloat is odd.
+//  a) for tan:  p8: tan(X) =  tan(r)
+//               p9: tan(X) = -cot(r)
+//  b) for cot:  p9: cot(X) =  cot(r)
+//               p8: cot(X) = -tan(r)
+//
+// Each is evaluated as a series. The p9 path requires 1/r.
+//
+// The coefficients used in the series are stored in a table as
+// are the pi constants.
+//
+// Registers used
+//==============================================================
+//
+// predicate registers used:
+// p6-12
+//
+// floating-point registers used:
+// f10-15, f32-106
+// f8, input
+//
+// general registers used
+// r14-26, r32-39

+// History
+//==============================================================
+// 02/02/00 Initial version
+// 04/04/00 Unwind support added
+// 12/27/00 Improved speed
+// 02/21/01 Updated to call tanl
+// 05/30/02 Improved speed, added cotf.
+// 11/25/02 Added explicit completer on fnorm
+// 02/10/03 Reordered header: .section, .global, .proc, .align
+// 04/17/03 Eliminated redundant stop bits
+// 03/31/05 Reformatted delimiters between data tables
+//
+// APIs
+//==============================================================
+// float tanf(float)
+// float cotf(float)
+//
+// Algorithm Description for tanf
+//==============================================================
+// The tanf function computes the principle value of the tangent of x,
+// where x is radian argument.
+//
+// There are 5 paths:
+// 1. x = +/-0.0
+//    Return tanf(x) = +/-0.0
+//
+// 2. x = [S,Q]NaN
+//    Return tanf(x) = QNaN
+//
+// 3. x = +/-Inf
+//    Return tanf(x) = QNaN
+//
+// 4. x = r + (Pi/2)*N, N = RoundInt(x*(2/Pi)), N is even, |r|<Pi/4
+//    Return tanf(x) = P19(r) = A1*r + A3*r^3 + A5*r^5 + ... + A19*r^19 =
+//    = r*(A1 + A3*t + A5*t^2 + ... + A19*t^9) = r*P9(t), where t = r^2
+//
+// 5. x = r + (Pi/2)*N, N = RoundInt(x*(2/Pi)), N is odd, |r|<Pi/4
+//    Return tanf(x) = -1/r + P11(r) = -1/r + B1*r + B3*r^3 + ... + B11*r^11 =
+//    = -1/r + r*(B1 + B3*t + B5*t^2 + ... + B11*t^5) = -1/r + r*P11(t),
+//    where t = r^2
+//
+// Algorithm Description for cotf
+//==============================================================
+// The cotf function computes the principle value of the cotangent of x,
+// where x is radian argument.
+//
+// There are 5 paths:
+// 1. x = +/-0.0
+//    Return cotf(x) = +/-Inf and error handling is called
+//
+// 2. x = [S,Q]NaN
+//    Return cotf(x) = QNaN
+//
+// 3. x = +/-Inf
+//    Return cotf(x) = QNaN
+//
+// 4. x = r + (Pi/2)*N, N = RoundInt(x*(2/Pi)), N is odd, |r|<Pi/4
+//    Return cotf(x) = P19(-r) = A1*(-r) + A3*(-r^3) + ... + A19*(-r^19) =
+//    = -r*(A1 + A3*t + A5*t^2 + ... + A19*t^9) = -r*P9(t), where t = r^2
+//
+// 5. x = r + (Pi/2)*N, N = RoundInt(x*(2/Pi)), N is even, |r|<Pi/4
+//    Return cotf(x) = 1/r + P11(-r) = 1/r + B1*(-r) + ... + B11*(-r^11) =
+//    = 1/r - r*(B1 + B3*t + B5*t^2 + ... + B11*t^5) = 1/r - r*P11(t),
+//    where t = r^2
+//
+//    We set p10 and clear p11 if computing tanf, vice versa for cotf.

+//
+// Algorithm description
+// ---------------------
+//
+// There are 4 paths:
+//
+// 1. Special path: x = 0, Inf, NaNs, denormals
+//    Return tanh(x) = +/-0.0 for zeros
+//    Return tanh(x) = QNaN for NaNs
+//    Return tanh(x) = sign(x)*1.0 for Inf
+//    Return tanh(x) = x + x^2   for - denormals
+//    Return tanh(x) = x - x^2   for + denormals
+//
+// 2. Near zero path: 0.0 < |x| < 0.25
+//    Return tanh(x) = x + x^3*A3 + ... + x^19*A19
+//
+// 3. Main path: 0.25 <= |x| < 19.0625
+//    For several ranges of 0.25 <= |x| < 19.0625
+//    Return tanh(x) = sign(x)*(A0 + y*A1 + y^2*A2 +
+//                                       + y^3*A3 + ... + y^19*A19)
+//    where y = (|x|/a) - b
+//
+//    For each range there is particular set of coefficients.
+//    Below is the list of ranges:
+//    1/4  <= |x| < 1/2     a = 0.25, b = 1.0
+//    1/2  <= |x| < 1.0     a = 0.5,  b = 1.0
+//    1.0  <= |x| < 2.0     a = 1.0,  b = 1.0
+//    2.0  <= |x| < 3.25    a = 2.0,  b = 1.0
+//    3.25 <= |x| < 4.0     a = 2.0,  b = 2.0
+//    4.0  <= |x| < 6.5     a = 4.0,  b = 1.0
+//    6.5  <= |x| < 8.0     a = 4.0,  b = 2.0
+//    8.0  <= |x| < 13.0    a = 8.0,  b = 1.0
+//    13.0 <= |x| < 16.0    a = 8.0,  b = 2.0
+//    16.0 <= |x| < 19.0625 a = 16.0, b = 1.0
+//    ( [3.25;4.0], [6.5;8.0], [13.0;16.0] subranges separated
+//                               for monotonicity issues resolve )
+//
+// 4. Saturation path: 19.0625 <= |x| < +INF
+//    Return tanh(x) = sign(x)*(1.0 - tiny_value)
+//    (tiny_value ~ 2^(-63))
+//
+// Registers used
+//==============================================================================
+// Floating Point registers used:
+// f8 = input, output
+// f32 -> f64
+//

+// r32 -> r51, r2, r3
+//
+// Predicate registers used:
+// p6, p8, p10, p11, p12, p14, p15
+// p6           arg is zero, denormal or special IEEE
+// p8           to filter out case when signd(x) > 1.625
+// p10          to filter out case when |x| < 0.25
+// p11          to filter out case when signd(x) <= 1.625
+// p12          to filter out case when |x| >= 19.0625
+// p14          set to 1 for positive x
+// p15          set to 1 for negative x

+// float tanhf(float)
+//
+// Overview of operation
+//==============================================================
+// Background
+//
+//
+// There are 9 paths:
+// 1. x = +/-0.0
+//    Return tanhf(x) = +/-0.0
+//
+// 2. 0.0 < |x| < 0.3125
+//    Return tanhf(x) = x + x^3*Pol3(x^2),
+//    where Pol3(x^2) = C3*x^6 + C2*x^4 + C1*x^2 + C0
+//
+// 3. 0.3125 <= |x| < 8.0
+//    Return tanhf(x) = sign(x)*PolD(x)*PolC(|x|) + sign(x)*PolA(|x|),
+//    where sign(x)*PolD(x) = sign(x)*(|x|^7 + D2*x^6 + D1*|x|^5 + D0*x^4),
+//          PolC(|x|) = B0*x^4 + C3*|x|^3 + C2*|x|^2 + C1*|x| + C0,
+//          PolA(|x|) = A3|x|^3 + A2*x^2 + A1*|x| + A0
+//
+//    Actually range 0.3125<=|x|< 8.0 is split to 5 subranges.
+//    For each subrange there is particular set of coefficients.
+//    Below is the list of subranges:
+//    3.1 0.3125 <= |x| < 0.5
+//    3.2 0.5 <= |x| < 1.0
+//    3.3 1.0 <= |x| < 2.0
+//    3.4 2.0 <= |x| < 4.0
+//    3.5 4.0 <= |x| < 8.0
+//
+// 4. 8.0 <= |x| < 9.125
+//    Return tanhf(x) = sign(x)*(A3|x|^3 + A2*x^2 + A1*|x| + A0)
+//
+// 5. 9.125 <= |x| < +INF
+//    Return tanhf(x) = sign(x)*(1.0d - 2^(-52))
+//
+// 6. |x| = INF
+//    Return tanhf(x) = sign(x) * 1.0
+//
+// 7. x = [S,Q]NaN
+//    Return tanhf(x) = QNaN
+//
+// 8. x is positive denormal
+//    Return tanhf(x) = x - x^2
+//
+// 9. x is negative denormal
+//    Return tanhf(x) = x + x^2
+//
+// Registers used
+//==============================================================
+// Floating Point registers used:
+// f8, input
+// f32 -> f59
+
+// General registers used:
+// r32 -> r46, r2, r3
+
+// Predicate registers used:
+// p0, p6 -> p15
+
+// p6           to filter out case when x = [Q,S]NaN or +/-0
+// p7           to filter out case when x = denormal
+// p8           set if |x| >= 0.3125, used also to process denormal input
+// p9           to filter out case when |x| = inf
+// p10          to filter out case when |x| < 0.3125
+// p11          to filter out case when 0.3125 <= |x| < 9.125
+// p12          to filter out case when |x| >= 9.125
+// p13          to filter out case when 8.0 <= |x| < 9.125
+// p14          set to 1 for positive x
+// p15          set to 1 for negative x

+//
+// Overview of operation
+//==============================================================
+//
+// Algorithm description
+// ---------------------
+//
+// There are 4 paths:
+//
+// 1. Special path: x = 0, Inf, NaNs, denormal
+//    Return tanhl(x) = +/-0.0 for zeros
+//    Return tanhl(x) = QNaN for NaNs
+//    Return tanhl(x) = sign(x)*1.0 for Inf
+//    Return tanhl(x) = x + x^2   for - denormals
+//    Return tanhl(x) = x - x^2   for + denormals
+//
+// 2. [0;1/8] path: 0.0 < |x| < 1/8
+//    Return tanhl(x) = x + x^3*A3 + ... + x^15*A15
+//
+// 3. Main path: 1/8 <= |x| < 22.8
+//    For several ranges of 1/8 <= |x| < 22.8
+//    Return tanhl(x) = sign(x)*((A0H+A0L) + y*(A1H+A1L) + y^2*(A2H+A2L) +
+//                                       + y^3*A3 + y^4*A4 + ... + y^25*A25 )
+//    where y = (|x|/a) - b
+//
+//    For each range there is particular set of coefficients.
+//    Below is the list of ranges:
+//    1/8  <= |x| < 1/4     a = 0.125, b = 1.5
+//    1/4  <= |x| < 1/2     a = 0.25,  b = 1.5
+//    1/2  <= |x| < 1.0     a = 0.5,   b = 1.5
+//    1.0  <= |x| < 2.0     a = 1.0,   b = 1.5
+//    2.0  <= |x| < 3.25    a = 2.0,   b = 1.5
+//    3.25 <= |x| < 4.0     a = 2.0,   b = 2.0
+//    4.0  <= |x| < 6.5     a = 4.0,   b = 1.5
+//    6.5  <= |x| < 8.0     a = 4.0,   b = 2.0
+//    8.0  <= |x| < 13.0    a = 8.0,   b = 1.5
+//    13.0 <= |x| < 16.0    a = 8.0,   b = 2.0
+//    16.0 <= |x| < 22.8    a = 16.0,  b = 1.5
+//    ( [3.25;4.0], [6.5;8.0], [13.9;16.0] subranges separated
+//                               for monotonicity issues resolve )
+//
+// 4. Saturation path: 22.8 <= |x| < +INF
+//    Return tanhl(x) = sign(x)*(1.0 - tiny_value)
+//    (tiny_value ~ 1e-1233)
+//
+// Implementation notes
+// --------------------
+//
+// 1. Special path: x = 0, INF, NaNa, denormals
+//
+//    This branch is cut off by one fclass operation.
+//    Then zeros+nans, infinities and denormals processed separately.
+//    For denormals we use simple fma operaton x+x*x (- for +denorms)
+//
+// 2. [0;1/8] path: 0.0 < |x| < 1/8
+//
+//    Here we use simple polynimial computations, where last step
+//    is performed as x + x^3*A3+...
+//    The rest of polynomial is factorized using binary tree technique.
+//
+// 3. Main path: 1/8 <= |x| < 22.8
+//
+//    Multiprecision have to be performed only for first few
+//    polynomial iterations (up to 3-rd x degree)
+//    Here we use the same parallelisation way as above:
+//    Split whole polynomial to first, "multiprecision" part, and second,
+//    so called "tail", native precision part.
+//
+//    1) Multiprecision part:
+//    [v1=(A0H+A0L)+y*(A1H+A1L)] + [v2=y^2*((A2H+A2L)+y*A3)]
+//    v1 and v2 terms calculated in parallel
+//
+//    2) Tail part:
+//    v3 = x^4 * ( A4 + x*A5 + ... + x^21*A25 )
+//    v3 is splitted to 2 even parts (10 coefficient in each one).
+//    These 2 parts are also factorized using binary tree technique.
+//
+//    So Multiprecision and Tail parts cost is almost the same
+//    and we have both results ready before final summation.
+//
+//    Some tricks were applied to maintain symmetry at direct
+//    rounding modes (to +/-inf). We had to set result sign
+//    not at the last operation but much more earlier and at
+//    several places.
+//
+// 4. Saturation path: 22.8 <= |x| < +INF
+//
+//    We use formula sign(x)*(1.0 - tiny_value) instead of simple sign(x)*1.0
+//    just to meet IEEE requirements for different rounding modes in this case.

+//    Below are mathematical and algorithmic descriptions for tanl.

+//    and invert sign of the computed result.
+//
+//*********************************************************************
+//
+// Mathematical Description
+//
+// We consider the computation of FPTANL of Arg. Now, given
+//
+//      Arg = N pi/2  + alpha,          |alpha| <= pi/4,
+//
+// basic mathematical relationship shows that
+//
+//      tan( Arg ) =  tan( alpha )     if N is even;
+//                 = -cot( alpha )      otherwise.
+//
+// The value of alpha is obtained by argument reduction and
+// represented by two working precision numbers r and c where
+//
+//      alpha =  r  +  c     accurately.
+//
+// The reduction method is described in a previous write up.
+// The argument reduction scheme identifies 4 cases. For Cases 2
+// and 4, because |alpha| is small, tan(r+c) and -cot(r+c) can be
+// computed very easily by 2 or 3 terms of the Taylor series
+// expansion as follows:
+//
+// Case 2:
+// -------
+//
+//      tan(r + c) = r + c + r^3/3          ...accurately
+//     -cot(r + c) = -1/(r+c) + r/3          ...accurately
+//
+// Case 4:
+// -------
+//
+//      tan(r + c) = r + c + r^3/3 + 2r^5/15     ...accurately
+//     -cot(r + c) = -1/(r+c) + r/3 + r^3/45     ...accurately
+//
+//
+// The only cases left are Cases 1 and 3 of the argument reduction
+// procedure. These two cases will be merged since after the
+// argument is reduced in either cases, we have the reduced argument
+// represented as r + c and that the magnitude |r + c| is not small
+// enough to allow the usage of a very short approximation.
+//
+// The greatest challenge of this task is that the second terms of
+// the Taylor series for tan(r) and -cot(r)
+//
+//      r + r^3/3 + 2 r^5/15 + ...
+//
+// and
+//
+//      -1/r + r/3 + r^3/45 + ...
+//
+// are not very small when |r| is close to pi/4 and the rounding
+// errors will be a concern if simple polynomial accumulation is
+// used. When |r| < 2^(-2), however, the second terms will be small
+// enough (5 bits or so of right shift) that a normal Horner
+// recurrence suffices. Hence there are two cases that we consider
+// in the accurate computation of tan(r) and cot(r), |r| <= pi/4.
+//
+// Case small_r: |r| < 2^(-2)
+// --------------------------
+//
+// Since Arg = N pi/4 + r + c accurately, we have
+//
+//      tan(Arg) =  tan(r+c)            for N even,
+//               = -cot(r+c)            otherwise.
+//
+// Here for this case, both tan(r) and -cot(r) can be approximated
+// by simple polynomials:
+//
+//      tan(r) =    r + P1_1 r^3 + P1_2 r^5 + ... + P1_9 r^19
+//     -cot(r) = -1/r + Q1_1 r   + Q1_2 r^3 + ... + Q1_7 r^13
+//
+// accurately. Since |r| is relatively small, tan(r+c) and
+// -cot(r+c) can be accurately approximated by replacing r with
+// r+c only in the first two terms of the corresponding polynomials.
+//
+// Note that P1_1 (and Q1_1 for that matter) approximates 1/3 to
+// almost 64 sig. bits, thus
+//
+//      P1_1 (r+c)^3 =  P1_1 r^3 + c * r^2     accurately.
+//
+// Hence,
+//
+//      tan(r+c) =    r + P1_1 r^3 + P1_2 r^5 + ... + P1_9 r^19
+//                     + c*(1 + r^2)
+//
+//        -cot(r+c) = -1/(r+c) + Q1_1 r   + Q1_2 r^3 + ... + Q1_7 r^13
+//               + Q1_1*c
+//
+//
+// Case normal_r: 2^(-2) <= |r| <= pi/4
+// ------------------------------------
+//
+// This case is more likely than the previous one if one considers
+// r to be uniformly distributed in [-pi/4 pi/4].
+//
+// The required calculation is either
+//
+//      tan(r + c)  =  tan(r)  +  correction,  or
+//     -cot(r + c)  = -cot(r)  +  correction.
+//
+// Specifically,
+//
+//      tan(r + c) =  tan(r) + c tan'(r)  + O(c^2)
+//                 =  tan(r) + c sec^2(r) + O(c^2)
+//                 =  tan(r) + c SEC_sq     ...accurately
+//                as long as SEC_sq approximates sec^2(r)
+//                to, say, 5 bits or so.
+//
+// Similarly,
+//
+//     -cot(r + c) = -cot(r) - c cot'(r)  + O(c^2)
+//                 = -cot(r) + c csc^2(r) + O(c^2)
+//                 = -cot(r) + c CSC_sq     ...accurately
+//                as long as CSC_sq approximates csc^2(r)
+//                to, say, 5 bits or so.
+//
+// We therefore concentrate on accurately calculating tan(r) and
+// cot(r) for a working-precision number r, |r| <= pi/4 to within
+// 0.1% or so.
+//
+// We will employ a table-driven approach. Let
+//
+//      r = sgn_r * 2^k * 1.b_1 b_2 ... b_5 ... b_63
+//        = sgn_r * ( B + x )
+//
+// where
+//
+//      B = 2^k * 1.b_1 b_2 ... b_5 1
+//      x = |r| - B
+//
+// Now,
+//                   tan(B)  +   tan(x)
+//      tan( B + x ) =  ------------------------
+//                   1 -  tan(B)*tan(x)
+//
+//               /                         \
+//               |   tan(B)  +   tan(x)          |
+
+//      = tan(B) +  | ------------------------ - tan(B) |
+//               |     1 -  tan(B)*tan(x)          |
+//               \                         /
+//
+//                 sec^2(B) * tan(x)
+//      = tan(B) + ------------------------
+//                 1 -  tan(B)*tan(x)
+//
+//                (1/[sin(B)*cos(B)]) * tan(x)
+//      = tan(B) + --------------------------------
+//                      cot(B)  -  tan(x)
+//
+//
+// Clearly, the values of tan(B), cot(B) and 1/(sin(B)*cos(B)) are
+// calculated beforehand and stored in a table. Since
+//
+//      |x| <= 2^k * 2^(-6)  <= 2^(-7)  (because k = -1, -2)
+//
+// a very short polynomial will be sufficient to approximate tan(x)
+// accurately. The details involved in computing the last expression
+// will be given in the next section on algorithm description.
+//
+//
+// Now, we turn to the case where cot( B + x ) is needed.
+//
+//
+//                   1 - tan(B)*tan(x)
+//      cot( B + x ) =  ------------------------
+//                   tan(B)  +  tan(x)
+//
+//               /                           \
+//               |   1 - tan(B)*tan(x)              |
+
+//      = cot(B) +  | ----------------------- - cot(B) |
+//               |     tan(B)  +  tan(x)            |
+//               \                           /
+//
+//               [tan(B) + cot(B)] * tan(x)
+//      = cot(B) - ----------------------------
+//                   tan(B)  +  tan(x)
+//
+//                (1/[sin(B)*cos(B)]) * tan(x)
+//      = cot(B) - --------------------------------
+//                      tan(B)  +  tan(x)
+//
+//
+// Note that the values of tan(B), cot(B) and 1/(sin(B)*cos(B)) that
+// are needed are the same set of values needed in the previous
+// case.
+//
+// Finally, we can put all the ingredients together as follows:
+//
+//      Arg = N * pi/2 +  r + c          ...accurately
+//
+//      tan(Arg) =  tan(r) + correction    if N is even;
+//               = -cot(r) + correction    otherwise.
+//
+// For Cases 2 and 4,
+//
+//     Case 2:
+//     tan(Arg) =  tan(r + c) = r + c + r^3/3           N even

+//
+// Overview
+//
+// The method consists of three cases.
+//
+// If       2 <= x < OVERFLOW_BOUNDARY      use case tgamma_regular;
+// else if    0 < x < 2                     use case tgamma_from_0_to_2;
+// else    if  -(i+1) <  x < -i, i = 0...184 use case tgamma_negatives;
+//
+// Case 2 <= x < OVERFLOW_BOUNDARY
+// -------------------------------
+//   Here we use algorithm based on the recursive formula
+//   GAMMA(x+1) = x*GAMMA(x). For that we subdivide interval
+//   [2; OVERFLOW_BOUNDARY] into intervals [16*n; 16*(n+1)] and
+//   approximate GAMMA(x) by polynomial of 22th degree on each
+//   [16*n; 16*n+1], recursive formula is used to expand GAMMA(x)
+//   to [16*n; 16*n+1]. In other words we need to find n, i and r
+//   such that x = 16 * n + i + r where n and i are integer numbers
+//   and r is fractional part of x. So GAMMA(x) = GAMMA(16*n+i+r) =
+//   = (x-1)*(x-2)*...*(x-i)*GAMMA(x-i) =
+//   = (x-1)*(x-2)*...*(x-i)*GAMMA(16*n+r) ~
+//   ~ (x-1)*(x-2)*...*(x-i)*P22n(r).
+//
+//   Step 1: Reduction
+//   -----------------
+//    N = [x] with truncate
+//    r = x - N, note 0 <= r < 1
+//
+//    n = N & ~0xF - index of table that contains coefficient of
+//                   polynomial approximation
+//    i = N & 0xF  - is used in recursive formula
+//
+//
+//   Step 2: Approximation
+//   ---------------------
+//    We use factorized minimax approximation polynomials
+//    P22n(r) = A22*(r^2+C01(n)*R+C00(n))*
+//              *(r^2+C11(n)*R+C10(n))*...*(r^2+CA1(n)*R+CA0(n))
+//
+//   Step 3: Recursion
+//   -----------------
+//    In case when i > 0 we need to multiply P22n(r) by product
+//    R(i)=(x-1)*(x-2)*...*(x-i). To reduce number of fp-instructions
+//    we can calculate R as follow:
+//    R(i) = ((x-1)*(x-2))*((x-3)*(x-4))*...*((x-(i-1))*(x-i)) if i is
+//    even or R = ((x-1)*(x-2))*((x-3)*(x-4))*...*((x-(i-2))*(x-(i-1)))*
+//    *(i-1) if i is odd. In both cases we need to calculate
+//    R2(i) = (x^2-3*x+2)*(x^2-7*x+12)*...*(x^2+x+2*j*(2*j-1)) =
+//    = (x^2-3*x+2)*(x^2-7*x+12)*...*((x^2+x)+2*j*(2*(j-1)+(1-2*x))) =
+//    = (RA+2*(2-RB))*(RA+4*(4-RB))*...*(RA+2*j*(2*(j-1)+RB))
+//    where j = 1..[i/2], RA = x^2+x, RB = 1-2*x.
+//
+//   Step 4: Reconstruction
+//   ----------------------
+//    Reconstruction is just simple multiplication i.e.
+//    GAMMA(x) = P22n(r)*R(i)
+//
+// Case 0 < x < 2
+// --------------
+//    To calculate GAMMA(x) on this interval we do following
+//        if 1 <= x < 1.25   than  GAMMA(x) = P15(x-1)
+//        if 1.25 <= x < 1.5 than  GAMMA(x) = P15(x-x_min) where
+//        x_min is point of local minimum on [1; 2] interval.
+//        if 1.5  <= x < 2.0 than  GAMMA(x) = P15(x-1.5)
+//    and
+//        if 0 < x < 1 than GAMMA(x) = GAMMA(x+1)/x
+//
+// Case -(i+1) <  x < -i, i = 0...184
+// ----------------------------------
+//    Here we use the fact that GAMMA(-x) = PI/(x*GAMMA(x)*sin(PI*x)) and
+//    so we need to calculate GAMMA(x), sin(PI*x)/PI. Calculation of
+//    GAMMA(x) is described above.
+//
+//   Step 1: Reduction
+//   -----------------
+//    Note that period of sin(PI*x) is 2 and range reduction for
+//    sin(PI*x) is like to range reduction for GAMMA(x)
+//    i.e r = x - [x] with exception of cases
+//    when r > 0.5 (in such cases r = 1 - (x - [x])).
+//
+//   Step 2: Approximation
+//   ---------------------
+//    To approximate sin(PI*x)/PI = sin(PI*(2*n+r))/PI =
+//    = (-1)^n*sin(PI*r)/PI Taylor series is used.
+//    sin(PI*r)/PI ~ S21(r).
+//
+//   Step 3: Division
+//   ----------------
+//    To calculate 1/(x*GAMMA(x)*S21(r)) we use frcpa instruction
+//    with following Newton-Raphson interations.

+//
+// Overview
+//
+// The method consists of three cases.
+//
+// If       2 <= x < OVERFLOW_BOUNDARY   use case tgamma_regular;
+// else if  0 < x < 2                    use case tgamma_from_0_to_2;
+// else if  -(i+1) <  x < -i, i = 0...43 use case tgamma_negatives;
+//
+// Case 2 <= x < OVERFLOW_BOUNDARY
+// -------------------------------
+//   Here we use algorithm based on the recursive formula
+//   GAMMA(x+1) = x*GAMMA(x). For that we subdivide interval
+//   [2; OVERFLOW_BOUNDARY] into intervals [8*n; 8*(n+1)] and
+//   approximate GAMMA(x) by polynomial of 22th degree on each
+//   [8*n; 8*n+1], recursive formula is used to expand GAMMA(x)
+//   to [8*n; 8*n+1]. In other words we need to find n, i and r
+//   such that x = 8 * n + i + r where n and i are integer numbers
+//   and r is fractional part of x. So GAMMA(x) = GAMMA(8*n+i+r) =
+//   = (x-1)*(x-2)*...*(x-i)*GAMMA(x-i) =
+//   = (x-1)*(x-2)*...*(x-i)*GAMMA(8*n+r) ~
+//   ~ (x-1)*(x-2)*...*(x-i)*P12n(r).
+//
+//   Step 1: Reduction
+//   -----------------
+//    N = [x] with truncate
+//    r = x - N, note 0 <= r < 1
+//
+//    n = N & ~0xF - index of table that contains coefficient of
+//                   polynomial approximation
+//    i = N & 0xF  - is used in recursive formula
+//
+//
+//   Step 2: Approximation
+//   ---------------------
+//    We use factorized minimax approximation polynomials
+//    P12n(r) = A12*(r^2+C01(n)*r+C00(n))*
+//              *(r^2+C11(n)*r+C10(n))*...*(r^2+C51(n)*r+C50(n))
+//
+//   Step 3: Recursion
+//   -----------------
+//    In case when i > 0 we need to multiply P12n(r) by product
+//    R(i,x)=(x-1)*(x-2)*...*(x-i). To reduce number of fp-instructions
+//    we can calculate R as follow:
+//    R(i,x) = ((x-1)*(x-2))*((x-3)*(x-4))*...*((x-(i-1))*(x-i)) if i is
+//    even or R = ((x-1)*(x-2))*((x-3)*(x-4))*...*((x-(i-2))*(x-(i-1)))*
+//    *(i-1) if i is odd. In both cases we need to calculate
+//    R2(i,x) = (x^2-3*x+2)*(x^2-7*x+12)*...*(x^2+x+2*j*(2*j-1)) =
+//    = ((x^2-x)+2*(1-x))*((x^2-x)+6*(2-x))*...*((x^2-x)+2*(2*j-1)*(j-x)) =
+//    = (RA+2*RB)*(RA+6*(1-RB))*...*(RA+2*(2*j-1)*(j-1+RB))
+//    where j = 1..[i/2], RA = x^2-x, RB = 1-x.
+//
+//   Step 4: Reconstruction
+//   ----------------------
+//    Reconstruction is just simple multiplication i.e.
+//    GAMMA(x) = P12n(r)*R(i,x)
+//
+// Case 0 < x < 2
+// --------------
+//    To calculate GAMMA(x) on this interval we do following
+//        if 1.0  <= x < 1.25  than  GAMMA(x) = P7(x-1)
+//        if 1.25 <= x < 1.5   than  GAMMA(x) = P7(x-x_min) where
+//              x_min is point of local minimum on [1; 2] interval.
+//        if 1.5  <= x < 1.75  than  GAMMA(x) = P7(x-1.5)
+//        if 1.75 <= x < 2.0   than  GAMMA(x) = P7(x-1.5)
+//    and
+//        if 0 < x < 1 than GAMMA(x) = GAMMA(x+1)/x
+//
+// Case -(i+1) <  x < -i, i = 0...43
+// ----------------------------------
+//    Here we use the fact that GAMMA(-x) = PI/(x*GAMMA(x)*sin(PI*x)) and
+//    so we need to calculate GAMMA(x), sin(PI*x)/PI. Calculation of
+//    GAMMA(x) is described above.
+//
+//   Step 1: Reduction
+//   -----------------
+//    Note that period of sin(PI*x) is 2 and range reduction for
+//    sin(PI*x) is like to range reduction for GAMMA(x)
+//    i.e rs = x - round(x) and |rs| <= 0.5.
+//
+//   Step 2: Approximation
+//   ---------------------
+//    To approximate sin(PI*x)/PI = sin(PI*(2*n+rs))/PI =
+//    = (-1)^n*sin(PI*rs)/PI Taylor series is used.
+//    sin(PI*rs)/PI ~ S17(rs).
+//
+//   Step 3: Division
+//   ----------------
+//    To calculate 1/x and 1/(GAMMA(x)*S12(rs)) we use frcpa
+//    instruction with following Newton-Raphson interations.

+// Algorithm description
+// ---------------------
+//
+// There are 3 main paths in the implementation
+// (and additional special values branches)
+//
+// 1) |X| >= 13 - Stirling formula computation
+//    a) Positive arguments:
+//       TGAMMAL(X) = exp((X-0.5)*ln(X) - X + C + S(Z)),
+//       where C = 0.5*ln(2*Pi) , Z = 1/Z, S(Z) - Bernulli polynomial
+//       (up to 'B18' term).
+//       Some of these calculation done in multiprecision.
+//       Ln returns multiprecision result too
+//       and exp also accepts and returns pair of values.
+//
+//    b) Negative arguments
+//       TGAMMAL(-X) = PI/(X*TGAMMAL(X)*sin(PI*X)).
+//       (X*sin(PI*X))/PI calculated in parallel with TGAMMAL.
+//       Here we use polynomial of 9th degree with 2 multiprecision steps.
+//       Argument range reduction is:
+//       N = [x] with round to nearest, r = x - N, -0.5 <= r < 0.5
+//       After ((X-0.5)*ln(X) - X + C + S(Z)) completed we just invert
+//       its result and compute exp with negative argument (1/exp(x)=exp(-x))
+//       Then we multiply exp result to PI/(X*sin(PI*X)).
+//
+// 2) 1 <= |X| < 13 - Polynomial part
+//    a) Positive arguments:
+//       All values are splitted to such intervals as:
+//       #0->[2;3], #1->[3,4], #2->[5,6]...
+//       For even intervals we just use polynomial computation with degree 20
+//       and first 6 multiprecision computations.
+//       Range reduction looks like
+//       N = [x] with truncate, r = x - N - 0.5, -0.5 <= r < 0.5
+//       For odd intervals we use reccurent formula:
+//       TGAMMAL(X) = TGAMMA(X-1)*(X-1)
+//       [1;2] interval is splitted to 3 subranges:
+//       [1;1.25], [1.25;1.75], [1.75;2] with the same polynomial forms
+//
+//    b) Negative arguments
+//       TGAMMAL(-X) = PI/(X*TGAMMAL(X)*sin(PI*X)).
+//       (X*sin(PI*X))/PI calculated in parallel with TGAMMAL.
+//       After multiplication by TGAMMAL(X) result we calculate reciprocal
+//       and get final result.
+//
+// 3) 0 < |X| < 1 - Near 0 part
+//    a) Here we use reccurent formula TGAMMAL(X) = TGAMMAL(X+1)/X
+//       TGAMMAL(X+1) calculated as shown above,
+//       1/X result obtained in parallel. Then we just multiply these values.
+//       There is only additional separated subrange: [0;0.125] with specific
+//       polynomial constants set.
+//
+//    b) Negative arguments
+//       TGAMMAL(-X) = PI/(TGAMMAL(X+1)*sin(PI*X)).
+//       There is no need to compute 1/X.
