* MACRO FORMAT
|
|
* ============
|
|
* This file contains inline assembly macros that
|
|
* generate AMD-3D instructions in binary format.
|
|
* Therefore, C or C++ programmer can use AMD-3D instructions
|
|
* without any penalty in their C or C++ source code.
|
|
*
|
|
* The macro's name and format conventions are as follow:
|
|
*
|
|
*
|
|
* 1. First argument of macro is a destination and
|
|
* second argument is a source operand.
|
|
* ex) _asm PFCMPEQ (m3, m4)
|
|
* | |
|
|
* dst src
|
|
*
|
|
* 2. The destination operand can be m0 to m7 only.
|
|
* The source operand can be any one of the register
|
|
* m0 to m7 or _eax, _ecx, _edx, _ebx, _esi, or _edi
|
|
* that contains effective address.
|
|
* ex) _asm PFRCP (M7, M6)
|
|
* ex) _asm PFRCPIT2 (m0, m4)
|
|
* ex) _asm PFMUL (m3, _edi)
|
|
*
|
|
* 3. The prefetch(w) takes one src operand _eax, ecx, _edx,
|
|
* _ebx, _esi, or _edi that contains effective address.
|
|
* ex) _asm PREFETCH (_edi)
|
|
*
|
|
* EXAMPLE
|
|
* =======
|
|
* Following program doesn't do anything but it shows you
|
|
* how to use inline assembly AMD-3D instructions in C.
|
|
* Note that this will only work in flat memory model which
|
|
* segment registers cs, ds, ss and es point to the same
|
|
* linear address space total less than 4GB.
|
|
*
|
|
* Used Microsoft VC++ 5.0
|
|
*
|
|
* #include <stdio.h>
|
|
* #include "amd3d.h"
|
|
*
|
|
* void main ()
|
|
* {
|
|
* float x = (float)1.25;
|
|
* float y = (float)1.25;
|
|
* float z, zz;
|
|
*
|
|
* _asm {
|
|
* movd mm1, x
|
|
* movd mm2, y
|
|
* pfmul (m1, m2)
|
|
* movd z, mm1
|
|
* femms
|
|
* }
|
|
*
|
|
* printf ("value of z = %f\n", z);

|
|
* //
|
|
* // Demonstration of using the memory instead of
|
|
* // multimedia register
|
|
* //
|
|
* _asm {
|
|
* movd mm3, x
|
|
* lea esi, y // load effective address of y
|
|
* pfmul (m3, _esi)
