No, but it produces better code for Atom, so its interesting.

I'll point out the ALS bug.

I'm trying to get Intel to directly respond to Mans' question on GCC version
compatibility.
I think the ICC compiler should be changed to support the following
attributes:

__attribute__((cold))__attribute__((flatten))__attribute__((force_align_arg_pointer))__attribute__((may_alias))

and then report at least gcc 4.3 front end compatibility
So the ifdef can be simplified to just
#if AV_GCC_VERSION_AT_LEAST(4,3)
