Sometimes I try it and benchmark it.
I use it only for compiling C files of codecs, like libavcodec and libmpeg2.
Anyway, there are few C-only files causing the compiler to crash :)
About 2 monts ago, i've got ~20% speedup when i recompiled a few files of
libavcodec with icc. Now I got 10% slowdown, thanks to Michael's
asm optimizations. So I don't recommend icc for mplayer now.
