I have made a quick browse through /usr/lib/rpm/rpmrc and I have noticed tht the
âhighestâ available x86 target is pentium4. GCC 4.1.0 allows for at least one
more target, namely prescott. The difference is that in opposite to pentium4,
prescott is able to use sse3 instruction set. It could speed up some programs a
consult redhat-rpm-config for actual opt flags used by the distro:
rpm -E '%optflags'
-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector
--param=ssp-buffer-size=4 -m32 -march=i386 -mtune=generic
