Some mnemonics like PMOVMSKB cannot even be expressed with the interface that
is offered. It returns a 32-bit word consisting of only the high bit of every
byte in the MMX or SSE register.
Since I've tried other workarounds up inline asm and hard coding hex values and
nothing worked, I've set this bug to 'major'.
The inline asm workaround usually ends in this:
Internal error: backend/cgcod.c 1561
But that's not what this bug report is about. I'm just stating that there are
more SIMD bugs lurking under the surface.
