[FFmpeg-devel] [PATCH] Allow optimization for pentium4 and core2 with icc

[Carl Eugen Hoyos]

Hi!

Attached patch allows to compile with icc when using --cpu=pentium4 or 
--cpu=core2. Both optimizations need (at least) linking against -lsvml 
which is done with this patch.

Please comment, Carl Eugen
