这个CFLAGS很过分吗？郁闷

orphen

其实我觉得楼主的CFLAGS并不过分，看看我的

1. CFLAGS="-march=k8 -mfpmath=sse -mmmx -msse -msse2 -msse3 -m3dnow -pipe -O3 -fomit-frame-pointer -fforce-addr -finline-functions -finline-limit=400 -fmove-all-movables -freduce-all-givs -freorder-blocks -freorder-functions -fexpensive-optimizations -falign-functions -falign-labels -falign-loops -falign-jumps -frename-registers -fweb -funit-at-a-time -fbranch-target-load-optimize -fbranch-target-load-optimize2"
   
2. CXXFLAGS="${CFLAGS}"

“There's alot of redundency there... and don't expect much sympathy if those cflags break things”
