  Optimizing for: corei7-avx

/usr/bin/clang -MMD -MP -D_ISOC99_SOURCE -I. -Iffmpeg -O2 -march=corei7-avx -pipe -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE -Ilibdvdread4 -mdynamic-no-pic -I/opt/local/include/lzo -I/opt/local/include -DPIC -fpie  -I/usr/X11/include -I/opt/local/include/opus  -c -o input/input.o input/input.c
'corei7-avx' is not a recognized processor for this target (ignoring processor)

It's doubtful whether this built an optimised version of mplayer…

clang-3.0 and later do:

$ clang-mp-3.0 -march=corei7-avx -c ~/testl.c 

$ clang-mp-2.9 -march=corei7-avx -c ~/testl.c 
'corei7-avx' is not a recognized processor for this target (ignoring processor)
