*cmiscdat.c - miscellaneous C run-time data
|
|
*
|
|
* Copyright (c) 1989-2001, Microsoft Corporation. All rights reserved.
|
|
*
|
|
*Purpose:
|
|
* Includes floating point conversion table (for C float output).
|
|
*
|
|
* When floating point I/O conversions are done, but no floating-point
|
|
* variables or expressions are used in the C program, we use the
|
|
* _cfltcvt_tab[] to map these cases to the _fptrap entry point,
|
|
* which prints "floating point not loaded" and dies.
|
|
*
|
|
* This table is initialized to six copies of _fptrap by default.
|
|
* If floating-point is linked in (_fltused), these table entries
|
|
* are reset (see input.c, output.c, fltused.asm, and fltuseda.asm).
|
|
*
|
|
*Revision History:
|
|
* 06-29-89 PHG module created, based on asm version
|
|
* 04-06-90 GJF Added #include <cruntime.h>. Also, fixed the copyright
|
|
* and cleaned up the formatting a bit.
|
|
* 07-31-90 SBM Updated comments slightly
|
|
* 08-29-90 SBM Added #include <internal.h> and <fltintrn.h>,
|
|
* removed _fptrap() prototype
|
|
* 04-19-93 SKS Remove obsolete variable _sigintoff
|
|
* 11-30-95 SKS Removed obsolete comments about 16-bit functionality.

|
