[PATCH] D27145: Add "RPRED" mechanism for relocation predicates. (5% speedup for `ld.lld -O0`)

[Joerg Sonnenberger via Phabricator via llvm-commits]

joerg added a comment.

The compiler would generally either have to know the overflow behavior of the left shift or add the one conditional I mentioned earlier. But otherwise I don't see why it can't create the transform.
