Hello all.

I recently installed x86_64 on my AMD64 Laptop and was a little disappointed that *MOST* apps to get them to work correctly needed to be used with 32bit emulation. I used to have x86 Gentoo on my box and was told to use CFLAGS "-march=athlon-xp -O2 -pipe -fomit-frame-pointer -msse2".

Is it possible now to just use:
Code:
-march=athlon64 -O2 -pipe -fomit-frame-pointer  ???


Or is that only for a 64bit install?

Thanks Again!

AFAIK -march=athlon64 implies -m64. Other than that and -msse2 they're the same thing, so I would stick to what we know doesn't explode if I were you ;)

In theory with a pure 32 bit install the -m64 should be pretty meaningless though so would probably work, as long as it doesn't affect the ABI setting too?

In short I haven't tried & wouldn't recommend it, but if you're going to let us know what happens :)

I use the following with no problems

-O3 -march=athlon-xp -fomit-frame-pointer -funroll-loops -pipe -m3dnow -mmmx -msse

Please see Which CFLAGS to you use to install gentoo-x86 on Athlon64 ?
