Hello all,
I am using Athlon64 X2 processor with the
CFLAGS="-march=k8 -O2 -pipe -fomit-frame-pointer" option.
Can I use the -march=native option instead of that?
You can see which options -march=native would use by running this command:
gcc -Q --help=target -march=native
(thanks to Daniel Iliev for the tip)
Perhaps I'm missing something but running the above gives me the impression that -march=native
actually only configures the bare minimal install. I'm not seeing -mmmx or -msse3 enabled on my
k8-sse3 for instance ( amongst much else ).
