This needs a test case. Going by the original 7MB reproducer I think we need a test case with a conditional branch where both operands are evaluated in different basic blocks but can be CSE'd. I think the compiler should have eliminated the branch as well though since 'bnec $5, $5, ...' is never going to be taken.
