|
*
|
|
*Purpose:
|
|
* This file contains constant and type definitions for handling
|
|
* floating point exceptions [ANSI/IEEE std. 754]
|
|
*
|
|
* [Public]
|
|
*
|
|
*Revision History:
|
|
* 03-01-92 GDP written
|
|
* 04-05-92 GDP calling convention macros
|
|
* 01-21-93 GJF Removed support for C6-386's _cdecl.
|
|
* 04-06-93 SKS Replace _CRTAPI1/2 with __cdecl, _CRTVAR1 with nothing
|
|
* 09-01-93 GJF Merged Cuda and NT SDK versions.
|
|
* 09-24-93 GJF Removed dummy args from _fpieee_flt prototype.
|
|
* 01-13-94 RDL Added #ifndef _LANGUAGE_ASSEMBLY for asm includes.
|
|
* 01-24-94 GJF Merged in 01-13 change above (from crt32 tree on
|
|
* \\orville\razzle).
|
|
* 11-03-94 GJF Ensure 8 byte alignment.
|
|
* 02-11-95 CFW Add _CRTBLD to avoid users getting wrong headers.
|
|
* 02-14-95 CFW Clean up Mac merge.
|
|
* 12-14-95 JWM Add "#pragma once".
|
|
* 02-21-97 GJF Cleaned out obsolete support for _CRTAPI* and _NTSDK.
|
|
* Also, detab-ed.
|
|
* 09-30-97 JWM Restored not-so-obsolete _CRTAPI1 support.
|
|
* 10-07-97 RDL Added IA64.
|
|
* 09-11-98 JWM Added Katmai exception support.
|
|
* 05-13-99 PML Remove _CRTAPI1
|
|
* 05-17-99 PML Remove all Macintosh support.
|
|
* 03-01-00 PML Add WNI exception support.
|
|
* 09-14-00 PML Add alignment for 64-bit, 128-bit types (vs7#160260).
|
|
* 03-24-01 PML Enable 64-bit/128-bit type alignment on x86.
|
|
* 06-13-01 PML Compile clean -Za -W4 -Tc (vs7#267063)
