Usage of AVX in 32 bit code

[Gunther]

I've Windows XP mode as an VM installed on my Win7. It works well. But there is one problem. By testing the support of the AVX instructions, such an easy instruction like:

Code Select Expand


        vmovaps    ymm0, [ecx]

is generating a GPF. The data array is aligned by 32, so what could be the reason? Any ideas?

Windows XP does not support AVX instructions. Also, it seems that Virtual PC only supports up to SSE2.

That could be the reason. Is there a better alternative?

1) don't use AVX instructions
or
2) use an environment  that supports them

Good proposal.
