Add support for the v1i64 type. This makes better code for this:
...
#include <mmintrin.h>
extern __m64 C;
void baz(__v2si *A, __v2si *B)
{
*A = C;
_mm_empty();
}
We get this:
_baz:
call "L1$pb"
"L1$pb":
popl %eax
movl L_C$non_lazy_ptr-"L1$pb"(%eax), %eax
movq (%eax), %mm0
movl 4(%esp), %eax
movq %mm0, (%eax)
emms
ret
GCC gives us this:
_baz:
pushl %ebx
call L3
"L00000000001$pb":
L3:
popl %ebx
subl $8, %esp
movl L_C$non_lazy_ptr-"L00000000001$pb"(%ebx), %eax
movl (%eax), %edx
movl 4(%eax), %ecx
