Synopsis:
    #include <mmintrin.h>
    __m64 _m_pxor(__m64 *m1, __m64 *m2);

Description:
    A bit-wise logical XOR is performed between 64-bit multimedia operands
    m1 and m2 and the result is stored in memory.

Returns:
    The bit-wise logical exclusive OR of two 64-bit values is returned.

Example:
    #include <stdio.h>
    #include <mmintrin.h>

    #define AS_QWORD "%16.16Lx"

    __m64   a;
    __m64   b = { 0x0123456789abcdef };
    __m64   c = { 0xfedcba9876543210 };

    void main()
      {
        a = _m_pxor( b, c );
        printf( "m1="AS_QWORD"\n"
                "m2="AS_QWORD"\n"
                "mm="AS_QWORD"\n",
                b, c, a );
      }

    produces the following:

    m1=0123456789abcdef
    m2=fedcba9876543210
    mm=ffffffffffffffff
