Some follow-up info...
I can get the below code to compile now and run on the mobile 6
emulator. However, if I uncomment the line __m64 ret =
_mm_adds_pi32( a, b ); below, I get the compile error that follows
it.
void _m_empty(void);
__m64 a = ;
__m64 b = ;
a.m64_u32[1] = 1;
b.m64_u32[1] = 2;
printf( "a.m64_u32: %d \n", a.m64_u32[ 1 ] );
// __m64 ret = _mm_adds_pi32( a, b );
Error 14 error C2275: '__m64' : illegal use of this type as an
expression
Error 15 error C2146: syntax error : missing ';' before identifier
'ret'
Error 16 error C2065: 'ret' : undeclared identifier
Error 17 error C2440: '=' : cannot convert from '__m64' to 'int'
Thanks,
Mike
