Remove llvm-upgrade and update tests. llvm-svn: 48103
2008-03-09 16:16:40 +08:00
Add a routine to swap branch instruction operands, and update any profile metadata at the same time. Use it to preserve metadata attached to a branch when re-writing it in InstCombine. Add metadata to the canonicalize_branch InstCombine test, and check that it is tranformed correctly. Reviewed by Nick Lewycky! llvm-svn: 142168
