*
* 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)
* movd zz, mm3
* femms
* }
*
* printf ("value of zz = %f\n", zz);
* }
