-//
-// 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.
