inline asm constraint for ymm0 register analogous to "Yz" for xmm0

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

Is there a inline asm constraint for ymm0 (AVX) register that works same way
as "Yz"()  for xmm0 (SSE)?
I have to use “x”() at the moment, but it loads to an arbitrary register
that should be moved to ymm0.

The best way to do this would be just to extend “Yz” so that it could handle
any type of *mm0 registers.
Or maybe use something like “x0”?
