joerg added a comment. There are two issues I have with the flags right now. The first one you are addressing with this patch. The second issue is they remain CC1-only flags. Can we introduce a proper "-emit-raw-llvm" flag to work like "-emit-llvm" but without the additional IR processing. We can make "-disable-llvm-optzns" an alias on the CC1-level for backwards compatibility. It is fine as a second step, but it would be nice to consider the big picture before shuffling things around.
