|
|
*
|
|
*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.

|
|
* include the * sizeof(int) factor [_WIN32_]
|
|
* 05-09-91 GJF Moved _JBLEN defs back to cruntime.h. Also, turn on
|
|

|
* 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.

|
|
* 04-07-93 SKS Add _CRTIMP keyword for CRT DLL model
|
|
* 04-13-93 SKS Remove _CRTIMP from _setjmp() -- it's an intrinsic

|
|
* 06-09-93 SRW Missing one line in previous merge.
|
|

|
|
* 10-11-93 GJF Merged NT and Cuda versions.

|
|
* 10-02-94 BWT Add PPC support.
|
|

|
* detab-ed.
|
|
* 09-30-97 JWM Restored not-so-obsolete _CRTAPI1 support.
|
|
* 10-07-97 RDL Added IA64.
