------------------------------------------------------------------------ r196294 | arnolds | 2013-12-03 08:33:06 -0800 (Tue, 03 Dec 2013) | 7 lines opt: Mirror vectorization presets of clang clang enables vectorization at optimization levels > 1 and size level < 2. opt should behave similarily. Loop vectorization and SLP vectorization can be disabled with the flags -disable-(loop/slp)-vectorization. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@196649 91177308-0d34-0410-b5e6-96231b3b80d8
