/***
*setjmp.h - definitions/declarations for setjmp/longjmp routines
*
* Copyright (c) 1985-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
* This file defines the machine-dependent buffer used by
* setjmp/longjmp to save and restore the program state, and
* declarations for those routines.
* [ANSI/System V]
*
* [Public]
*
*Revision History:
* 12-11-87 JCR Added "_loadds" functionality
* 12-18-87 JCR Added _FAR_ to declarations
* 02-10-88 JCR Cleaned up white space
* 05-03-89 JCR Added _INTERNAL_IFSTRIP for relinc usage
* 08-15-89 GJF Cleanup, now specific to OS/2 2.0 (i.e., 386 flat model)
* 10-30-89 GJF Fixed copyright
* 11-02-89 JCR Changed "DLL" to "_DLL"
* 03-01-90 GJF Added #ifndef _INC_SETJMP and #include <cruntime.h>
* stuff. Also, removed some (now) useless preprocessor
* directives.
* 04-10-90 GJF Replaced _cdecl with _CALLTYPE1.
* 05-18-90 GJF Revised for SEH.
* 10-30-90 GJF Moved definition of _JBLEN into cruntime.h.
* 02-25-91 SRW Moved definition of _JBLEN back here [_WIN32_]
* 04-09-91 PNT Added _MAC_ definitions
* 04-17-91 SRW Fixed definition of _JBLEN for i386 and MIPS to not
* include the * sizeof(int) factor [_WIN32_]
* 05-09-91 GJF Moved _JBLEN defs back to cruntime.h. Also, turn on
* intrinsic _setjmp for Dosx32.
* 08-27-91 GJF #ifdef out everything for C++.
* 08-29-91 JCR ANSI naming
* 11-01-91 GDP MIPS compiler support -- Moved _JBLEN back here
* 01-16-92 GJF Fixed _JBLEN and map to _setjmp intrinsic for i386
* target [_WIN32_].
* 05-08-92 GJF Changed _JBLEN to support C8-32 (support for C6-386 has
* been dropped).
* 08-06-92 GJF Function calling type and variable type macros. Revised
* use of compiler/target processor macros.
* 11-09-92 GJF Fixed some preprocessing conditionals.
* 01-03-93 SRW Fold in ALPHA changes
* 01-09-93 SRW Remove usage of MIPS and ALPHA to conform to ANSI
* Use _MIPS_ and _ALPHA_ instead.
* 01-21-93 GJF Removed support for C6-386's _cdecl.
* 02-20-93 GJF Per ChuckG and MartinO, setjmp/longjmp to used in
* C++ programs.
* 03-23-93 SRW Change _JBLEN for MIPS in preparation for SetJmpEx
* 04-06-93 SKS Replace _CRTAPI1/2 with __cdecl, _CRTVAR1 with nothing
* 04-07-93 SKS Add _CRTIMP keyword for CRT DLL model
* 04-13-93 SKS Remove _CRTIMP from _setjmp() -- it's an intrinsic
* 04-23-93 SRW Added _JBTYPE and finalized setjmpex support.
* 06-09-93 SRW Missing one line in previous merge.
* 10-04-93 SRW Fix ifdefs for MIPS and ALPHA to only check for
* _M_?????? defines
* 10-11-93 GJF Merged NT and Cuda versions.
* 01-12-93 PML Increased x86 _JBLEN from 8 to 16. Added new fields
* to _JUMP_BUFFER for use with C9.0.
* 06-16-94 GJF Fix for MIPS from Steve Hanson (Dolphin bug #13818)
* 10-02-94 BWT Add PPC support.
* 11-03-94 GJF Ensure 8 byte alignment.
* 12-29-94 JCF Merged with mac header.
* 01-13-95 JWM Added NLG prototypes.
* 02-11-95 CFW Add _CRTBLD to avoid users getting wrong headers.
* 02-14-95 CFW Clean up Mac merge.
* 06-23-95 JPM Use _setjmp with PowerPC VC compiler
* 12-14-95 JWM Add "#pragma once".
* 04-15-95 BWT Add _setjmpVfp (setjmp with Virtual Frame Pointer) for MIPS
* 08-13-96 BWT Redefine _setjmp to _setjmp on MIPS also
* 02-21-97 GJF Cleaned out obsolete support for _NTSDK. Also,
* detab-ed.
* 09-30-97 JWM Restored not-so-obsolete _CRTAPI1 support.
* 10-07-97 RDL Added IA64.
* 10-02-97 RDL IA64 - 16-byte align jmp_buf and _JUMP_BUFFER.
* 05-13-99 PML Remove _CRTAPI1
* 05-17-99 PML Remove all Macintosh support.
* 10-25-99 PML Temporarily issue error on _M_CEE (VS7#54572).
* 02-25-00 PML Remove _M_CEE error (VS7#81945).
* 11-08-00 PML Remove IA64 FPSR storage, rename reserveds (vs7#182574)
* 11-17-00 PML Put back IA64 FPSR (backing out vs7#182574)
* 03-19-01 BWT Add AMD64 definitions
* 06-13-01 PML Compile clean -Za -W4 -Tc (vs7#267063)
* 07-15-01 PML Remove all ALPHA, MIPS, and PPC code
