 *
 * 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);
