+Wed May 3 13:59:54 MDT 1995 Bryan Ford <baford@cs.utah.edu>
+
+ Merged in diffs from UK02p12 to UK02p15:
+
+ Wed May 3 10:47:41 MDT 1995 Bryan Ford <baford@cs.utah.edu>
+
+ * Released UK02p15.
+
+ * mig_string.h: include string.h instead of strings.h
+
+ * user.c, lexxer.l: changed index/rindex to strchr/strrchr.
+
+Fri Feb 10 13:25:54 MST 1995 Bryan Ford <baford@cs.utah.edu>
+
+ Merged in diffs from UK02p7 to UK02p9:
+
+ Sun, 29 Jan 1995 Remy.Card@masi.ibp.fr (Remy CARD)
+
+ Fixed a bug that causes mig to generate bad file names
+ in #include directives when generating the user source file.
+
+Fri Nov 25 13:56:32 MST 1994 Bryan Ford (baford@cs.utah.edu)
+
+ Merged in diffs from UK02p6 to UK02p7:
+
+ * MIG now compiles under BSD without 'vm_???_t' types
+ conflicting between host (BSD) and target (Mach)
+ header files. Basically, the MIG source files compiled
+ to run on the host machine no longer include mach/message.h;
+ instead they get the needed defines through cpu.h
+ which is built by compiling cpu.sym for the target machine.
+
+Mon Aug 29 18:31:21 1994 Bryan Ford (baford@cs.utah.edu)
+
+ * got rid of /usr/bin pathname in call to basename:
+ basename isn't always in /usr/bin.
+
+Fri Aug 26 11:36:10 1994 Louis-D. Dubeau (hallu@info.polymtl.ca)
+
+ * Fixed mig.sh to pass -imacros flags to CPP correctly.
+
+Tue Sep 6 10:00:29 1994 Roland McGrath (roland@churchy.gnu.ai.mit.edu)
+
+ * Released UK02p6.
+

+
+ * Other minor portability fixes.
+
+Mon Aug 15 18:37:47 1994 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
+
+ * global.c (more_global): Prepend RoutinePrefix to ServerDemux
+ even for non-default value of ServerDemux.
+
+Fri Jul 8 14:36:53 1994 Roland McGrath (roland@churchy.gnu.ai.mit.edu)
+
+ * routine.h (rtSkip): Take int arg.
+ * routine.c (rtSkip): Take int arg and increment by that many.
+ * parser.y (Statement): Grok `skip N;'; pass int arg to rtSkip.
+
+Fri May 13 15:08:56 1994 Michael I Bushnell (mib@churchy.gnu.ai.mit.edu)
+
+ * user.c (WriteMsgCheckReceive): Deallocate the reply port also if
+ we get one of the send errors that can cause the message to be
+ partially sent and then destroyed; otherwise we might later get a
+ spurious send-once notification.
+
+Wed Aug 4 10:34:42 1993 Michael I. Bushnell (mib at ernst.gnu.ai.mit.edu)
+
+ * Makefile: Don't use flex or bison; use lex and yacc instead.

+ *
+ * DESIGN:
+ * Mig uses a lexxer module created by lex from lexxer.l and
+ * a parser module created by yacc from parser.y to parse an
+ * interface definitions module for a mach server.
+ * The parser module calls routines in statement.c
+ * and routines.c to build a list of statement structures.
+ * The most interesting statements are the routine definitions
+ * which contain information about the name, type, characteristics
+ * of the routine, an argument list containing information for
+ * each argument type, and a list of special arguments. The
+ * argument type structures are build by routines in type.c
+ * Once parsing is completed, the three code generation modules:
+ * header.c user.c and server.c are called sequentially. These
+ * do some code generation directly and also call the routines
+ * in utils.c for common (parameterized) code generation.

+ * ABSTRACT:
+ * Provides the routine used by parser.c to generate

+ * The parser generates a threaded list of statements
+ * of which the most interesting are the various kinds
+ * routine statments. The routine structure is defined
+ * in routine.h which includes it name, kind of routine
+ * and other information,
+ * a pointer to an argument list which contains the name
+ * and type information for each argument, and a list
+ * of distinguished arguments, eg. Request and Reply
+ * ports, waittime, retcode etc.

+ * reply msg. These bits (with akbReplyInit, akbRequestQC, akbReplyQC)
+ * control msg structure declarations packing, and checking of
+ * mach_msg_type_t fields.
+ *
+ * akbUserArg means this argument is an argument to the user-side stub.
+ * akbServerArg means this argument is an argument to
+ * the server procedure called by the server-side stub.
+ *
+ * The akbSend* and akbReturn* bits control packing/extracting values
+ * in the request and reply messages.
+ *
+ * akbSend means the argument's value is carried in the request msg.
+ * akbSendBody implies akbSend; the value is carried in the msg body.
+ * akbSendSnd implies akbSend; the value is stuffed into the request.
+ * akbSendRcv implies akbSend; the value is pulled out of the request.
+ *
+ * akbReturn, akbReturnBody, akbReturnSnd, akbReturnRcv are defined
+ * similarly but apply to the reply message.
+ *
+ * User-side code generation (header.c, user.c) and associated code
+ * should use akbSendSnd and akbReturnRcv, but not akbSendRcv and
+ * akbReturnSnd. Server-side code generation (server.c) is reversed.
+ * Code generation should use the more specific akb{Send,Return}{Snd,Rcv}
+ * bits when possible, instead of akb{Send,Return}.
+ *
+ * Note that akRetCode and akReturn lack any Return bits, although
+ * there is a value in the msg. These guys are packed/unpacked
+ * with special code, unlike other arguments.
+ *
+ * akbReplyInit implies akbReply. It means the server-side stub
+ * should initialize the argument's msg_type field in the reply msg.
+ * Some special arguments (RetCode, Dummy, Tid) have their msg_type
+ * fields in the reply message initialized by the server demux
+ * function; these arguments have akbReply but not akbReplyInit.
+ *
+ * akbRequestQC implies akbRequest. If it's on, then the
+ * mach_msg_type_t value in the request message can be checked quickly
+ * (by casting to an int and checking with a single comparison).
+ * akbReplyQC has the analogous meaning with respect to akbReply.
+ *
+ * akbVariable means the argument has variable-sized inline data.
+ * It isn't currently used for code generation, but routine.c
+ * does use it internally. It is added in rtAugmentArgKind.
+ *
+ * akbReplyCopy and akbVarNeeded help control code generation in the
+ * server-side stub. The preferred method of handling data in the
+ * server-side stub avoids copying into/out-of local variables. In
+ * arguments get passed directly to the server proc from the request msg.
+ * Out arguments get stuffed directly into the reply msg by the server proc.
+ * For InOut arguments, the server proc gets the address of the data in
+ * the request msg, and the resulting data gets copied to the reply msg.
+ * Some arguments need a local variable in the server-side stub. The
+ * code extracts the data from the request msg into the variable, and
+ * stuff the reply msg from the variable.
+ *
+ * akbReplyCopy implies akbReply. It means the data should get copied
+ * from the request msg to the reply msg after the server proc is called.
+ * It is only used by akInOut. akTid doesn't need it because the tid
+ * data in the reply msg is initialized in the server demux function.
+ *
+ * akbVarNeeded means the argument needs a local variable in the
+ * server-side stub. It is added in rtAugmentArgKind and
+ * rtCheckVariable. An argument shouldn't have all three of
+ * akbReturnSnd, akbVarNeeded and akbReplyCopy, because this indicates
+ * the reply msg should be stuffed both ways.
+ *
+ * akbDestroy helps control code generation in the server-side stub.
+ * It means this argument has a destructor function which should be called.
+ *
+ * Header file generation (header.c) uses:
+ * akbUserArg
+ *
+ * User stub generation (user.c) uses:
+ * akbUserArg, akbRequest, akbReply, akbSendSnd,
+ * akbSendBody, akbReturnRcv, akbReplyQC
+ *
+ * Server stub generation (server.c) uses:
+ * akbServerArg, akbRequest, akbReply, akbSendRcv, akbReturnSnd,
+ * akbReplyInit, akbReplyCopy, akbVarNeeded, akbSendBody, akbRequestQC
+ *
+ *
+ * During code generation, the routine, argument, and type data structures
+ * are read-only. The code generation functions' output is their only
+ * side-effect.

+ * The symbol table is a simple self-organizing linked list.
+ *
+ * The function itCheckDecl checks & fills in computed information.
+ * Every type actually used (pointed at by argType) is so processed.
+ *
+ * The itInName, itOutName, itSize, itNumber, itInLine, itLongForm,
+ * and itDeallocate fields correspond directly to mach_msg_type_t fields.
+ * For out-of-line variable sized types, itNumber is zero. For
+ * in-line variable sized types, itNumber is the maximum size of the
+ * array. itInName is the msgt_name value supplied to the kernel,
+ * and itOutName is the msgt_name value received from the kernel.
+ * Either or both may be MACH_MSG_TYPE_POLYMORPHIC, indicating a
+ * "polymorphic" msgt_name. For itInName, this means the user
+ * supplies the value with an argument. For itOutName, this means the
+ * the value is returned in an argument.
+ *
+ * The itInNameStr and itOutNameStr fields contain "printing" versions
+ * of the itInName and itOutName values. The mapping from number->string
+ * is not into (eg, MACH_MSG_TYPE_UNSTRUCTURED/MACH_MSG_TYPE_BOOLEAN/
+ * MACH_MSG_TYPE_BIT). These fields are used for code-generation and
+ * pretty-printing.
+ *
+ * itFlags contains the user's requests for itLongForm and itDeallocate
+ * values. itCheckDecl takes it into account when setting itLongForm
+ * and itDeallocate, but they can be overridden (with a warning message).
+ *
+ * itTypeSize is the calculated size of the C type, in bytes.
+ * itPadSize is the size of any padded needed after the data field.
+ * itMinTypeSize is the minimum size of the data field, including padding.
+ * For variable-length inline data, it is zero.
+ *
+ * itUserType, itServerType, itTransType are the C types used in
+ * code generation. itUserType is the C type passed to the user-side stub
+ * and used for msg declarations in the user-side stub. itServerType
+ * is the C type used for msg declarations in the server-side stub.
+ * itTransType is the C type passed to the server function by the
+ * server-side stub. Normally it differs from itServerType only when
+ * translation functions are defined.
+ *
+ * itInTrans and itOutTrans are translation functions. itInTrans
+ * takes itServerType values and returns itTransType values. itOutTrans
+ * takes itTransType vaulues and returns itServerType values.
+ * itDestructor is a finalization function applied to In arguments
+ * after the server-side stub calls the server function. It takes
+ * itTransType values. Any combination of these may be defined.
+ *
+ * The following type specification syntax modifies these values:
+ * type new = old
+ * ctype: name // itUserType and itServerType
+ * cusertype: itUserType
+ * cservertype: itServerType
+ * intran: itTransType itInTrans(itServerType)
+ * outtran: itServerType itOutTrans(itTransType)
+ * destructor: itDestructor(itTransType);
+ *
+ * At most one of itStruct and itString should be TRUE. If both are
+ * false, then this is assumed to be an array type (msg data is passed
+ * by reference). If itStruct is TRUE, then msg data is passed by value
+ * and can be assigned with =. If itString is TRUE, then the msg_data
+ * is a null-terminated string, assigned with strncpy. The itNumber
+ * value is a maximum length for the string; the msg field always
+ * takes up this much space.
+ *
+ * itVarArray means this is a variable-sized array. If it is inline,
+ * then itStruct and itString are FALSE. If it is out-of-line, then
+ * itStruct is TRUE (because pointers can be assigned).
+ *
+ * itIndefinite means this is an indefinite-length array - it may be sent
+ * either inline or out-of-line. itNumber is assigned so that at most
+ * 2048 bytes are sent inline.
+ *
+ * itElement points to any substructure that the type may have.
+ * It is only used with variable-sized array types.

+ * successive arguments (left-to-right), as is the case for a machine
+ * with a downward-growing stack with arguments pushed right-to-left.
+ *
+ * To write, for example, fprintf() using this routine, the code
+ *
+ * fprintf(fd, format, args)
+ * FILE *fd;
+ * char *format;
+ * {
+ * _doprnt_ansi(format, &args, fd);
+ * }
+ *
+ * would suffice. (This example does not handle the fprintf's "return
+ * value" correctly, but who looks at the return value of fprintf
+ * anyway?)
+ *
+ * This version implements the following printf features:
+ *
+ * %d decimal conversion
+ * %u unsigned conversion
+ * %x hexadecimal conversion
+ * %X hexadecimal conversion with capital letters
+ * %o octal conversion
+ * %c character
+ * %s string
+ * %m.n field width, precision
+ * %-m.n left adjustment
+ * %0m.n zero-padding
+ * %*.* width and precision taken from arguments
+ *
+ * This version does not implement %f, %e, or %g. It accepts, but
+ * ignores, an `l' as in %ld, %lo, %lx, and %lu, and therefore will not
+ * work correctly on machines for which sizeof(long) != sizeof(int).
+ * It does not even parse %D, %O, or %U; you should be using %ld, %o and
+ * %lu if you mean long conversion.
+ *
+ * As mentioned, this version does not return any reasonable value.
+ *
+ * Permission is granted to use, modify, or propagate this code as
+ * long as this notice is incorporated.
