[Ffmpeg-devel] Anyone tried Intel compiler?

I haven't used it on ffmpeg, but have on similar
code (signal processing and 3D rendering). We
typically saw a measurable speed increase for fp math.
However, one issue to be aware of is that the ICC
compiler intentionally cripples SIMD-optimized
routines when not running on P4 architecture. (All
AMD and even P3) Because we had a mix of P3, P4, and
AMD machines, over-all/averaged performance was lower
than with gcc.
