*crt0fp.asm - floating point not loaded trap

|
|
* Copyright (c) 1989-2001, Microsoft Corporation. All rights reserved.
|
||
|
|
*
|
||
|
|
*Purpose:
|
||
|
|
* To trap certain cases where certain necessary floating-point
|
||
|
|
* software is not loaded. Two specific cases are when no emulator
|
||
|
|
* is linked in but no coprocessor is present, and when floating
|
||
|
|
* point i/o conversions are done, but no floating-point variables
|
||
|
|
* or expressions are used in the program.
|
||
|
|
*
|
||
|
|
*Revision History:
|
||
|
|
* 06-29-89 PHG module created, based on asm version
|
||
|
|
* 04-09-90 GJF Added #include <cruntime.h>. Made calling type
|
||
|
|
* _CALLTYPE1. Also, fixed the copyright.
|
||
|
|
* 04-10-90 GJF Fixed compiler warnings (-W3).
|
||
|
|
* 10-08-90 GJF New-style function declarator.
|
||
|
|
* 10-11-90 GJF Changed _amsg_exit() interface.
|
||
|
|
* 04-06-93 SKS Replace _CRTAPI* with __cdecl

*_fptrap - trap for missing floating-point software
|
||
|
|
*
|
||
|
|
*Purpose:
|
||
|
|
* Catches these cases of incomplete f.p. software linked into a program.
|
||
|
|
*
|
||
|
|
* (1) no coprocessor present, and no emulator linked in
|
||
|
|
*
|
||
|
|
* (2) "%e", "%f", and "%g" i/o conversion formats specified, but
|
||
|
|
* not all conversion software has been linked in, because the
|
||
|
|
* program did not use any floating-point variables or expressions.
|
||
|
|
*
|
||
|
|
*Entry:
|
||
|
|
* None.
|
||
|
|
*
|
||
|
|
*Exit:
|
||
|
|
* Never returns.
|
||
|
|
*
|
||
|
|
*Exceptions:
|
||
|
|
* Transfers control to _amsg_exit which ...
|
||
|
|
* - Writes error message to standard error: "floating point not loaded"
|
||
|
|
* - Terminates the program by calling _exit().
