Re: [gentoo-user] Re: CFLAGS "...-O3 -pipe" vs "...O2 "

[Andrey Vul]

don't use -O3 unless you need _extreme_ performance
-O2 -finline-functions is close to -O3 but doesn't use -fno-home-register
For toolchain, I just stick to -O2. For power-hungry apps, I use -O2
-finline-functions
glibc developer said that inlining with gcc 4.2 screws up code, so on
the safe side, just use -O2 for toolchain, -O2 -finline-functions for
everything else
