I understand that Morgan-core Durons (the >1GHz ones I believe) are just Athlon-XP's with less cache, so you can use -march=athlon-xp which will be (slightly) faster. My CFLAGS for an Athlon XP 1800+ are: CFLAGS="-march=athlon-xp -O3 -pipe -mcpu=athlon-xp -m3dnow -mmmx -msse -mfpmath=sse,387 -finline-functions -fmerge-all-constants -fthread-jumps -fomit-frame-pointer -fexpensive-optimizations -ffast-math -fforce-addr -falign-functions=64 -falign-jumps=4 -falign-loops=4 -frerun-cse-after-loop -frerun-loop-opt -fprefetch-loop-arrays -maccumulate-outgoing-args" Which contains some duplications but _seems_ to work perfectly. Note this will probably make people cry "Are you crazy and/or stupid!?" and developers will likely refuse to do troubleshooting on any problems you may have. -Eric -- I know it all.
