AMD embraces AVX making a new superset with SSE5(256bit support)

[Hans de Vries]

More information on AVX support in BD cores,directly from senior architect Mr. Christie,as response to Agner Fog's inquiry in comments section of the blog.

According to Dave Christie, AMD will support all Intel instructions in Bulldozer, including AVX, SSE4.1-2, AES and PCLMULQDQ.

So, everthing fine, everthing ok, so far for compatibility.
It takes an astounding endurance and resilience to get the message through though.

It might well be that it's not true that Intel changed the FMA stuff just to make things hard for AMD.
They had no real obligation to publish AVX that early anyway. It's more likely simply an implementation issue.
