...oes not clear the MMX state using emms?
For my project I'm already manually inserting emms instructions in the right
places, so I'd really like 64-bit vector operations to be lowered to MMX
instructions for best performance. So is there some way to get that behavior
back? I tried making IsVerbotenVectorType return false but that didn't
appear to help.
