Hi, can anybody tell me what are the cflags for an Athlon 1G? Thanks very much!

well... i've never heard of flags for different chip architectures... although it makes sense that they should exist...

does anyone else have any light to shine on this one? i feel like i should know this

gcc-2.95
CFLAGS = -s -static -O3 -fomit-frame-pointer -Wall
-mcpu=pentiumpro \
-march=pentiumpro -malign-functions=4 -funroll-loops \
-fexpensive-optimizations -malign-double
-fschedule-insns2 \
-mwide-multiply

gcc-3.x
CFLAGS = -s -static -O3 -fomit-frame-pointer -Wall \
-mcpu=athlon \
-march=athlon -malign-functions=4 -funroll-loops \
-fexpensive-optimizations -malign-double \
-fschedule-insns2 \
-mwide-multiply

Thanks to guys at AMD support and the source article (somewhat dated) at : http://aboutlinux.com/art_k7opt1_a.html.

Good luck.
