I've looked through the AVS2/AVS ... includes, but can't figure out the intended syntax for this instruction. I've tried a number of possiblities:

Code:


vpmovsxdq ymm0,:16 [mem]
vpmovsxdq ymm0,:32 [mem]

vpmovsxdq ymm0,dqword [mem]
vpmovsxdq ymm0,yword [mem]

vpmovsxdq ymm0,dqword ptr [mem]
vpmovsxdq ymm0, ptr [mem]

I could only get it to work by removing all type information from the memory definition and the instruction. But it would be nice to know how to override this one.

DQWORD does work. Embarassed

Thought for sure that I'd tried that.

DQWORD also has a synonym XWORD. Please note the symmetry:

Code:

VPMOVSXDQ ymm1, xmm2
VPMOVSXDQ ymm1, xword [mem]
