Instead of doing a RPO traversal of the whole function remember the blocks containing gathers (typically <= 2) and scan them in dominator-first order. The actual CSE is still quadratic, but I'm not confident that adding a scoped hash table here is worth it as we're only looking at the generated instructions and not arbitrary code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193956 91177308-0d34-0410-b5e6-96231b3b80d8 |
