in r86005 and unintentionally changed the default from -O3 to -O2. - It's odd the things automated perf testing turns up! :) - Also, the configure diff is messed up slightly. It looks like someone either didn't regenerate configure correctly (or I didn't), or autoconf has some funnyness in it. Eric, any ideas? This has been at -O2 for so long, that I am slightly nervous that this change will uncover miscompiles of LLVM on other systems. If that is the case, I think we should just set the default universally at -O3, and let developers/vendors use -O3 if they want it and have tested it. llvm-svn: 100941
