- From the gcc manpage:

- -O2 turns on all optimization flags specified by -O. It 
also turns on the following optimization flags: -fforce-mem 
- -foptimize-sibling-calls -fstrength-reduce -fcse-follow-jumps 
- -fcse-skip-blocks -frerun-cse-after-loop -frerun-loop-opt 
- -fgcse -fgcse-lm -fgcse-sm -fgcse-las -fdelete-null-pointer-checks 
- -fexpensive-optimizations -fregmove -fschedule-insns 
- -fschedule-insns2 -fsched-interblock -fsched-spec -fcaller-saves 
- -fpeephole2 -freorder-blocks -freorder-functions -fstrict-aliasing 
- -funit-at-a-time -falign-functions -falign-jumps -falign-loops 
^^^^^^^^^^^^^^^^
- -falign-labels -fcrossjumping 
Do I miss something?
