Sanjay Patel 8f04b72eb3 [PassManager] adjust VectorCombine placement ... The initial placement of vector-combine in the opt pipeline revealed phase ordering bugs: https://bugs.llvm.org/show_bug.cgi?id=45015 https://bugs.llvm.org/show_bug.cgi?id=42022 This patch contains a few independent changes: 1. Move the pass up in the pipeline, so it happens just after loop-vectorization. This is only to keep vectorization passes together in the pipeline at the moment. I don't have evidence of interaction between these yet. 2. Add an -early-cse pass after -vector-combine to clean up redundant ops. This was partly proposed as far back as rL219644 (which is why it's effectively being moved in the old PM code). This is important because the subsequent -instcombine doesn't work as well without EarlyCSE. With the CSE, -instcombine is able to squash shuffles together in 1 of the tests (because those are simple "select" shuffles). 3. Remove the -vector-combine pass that was running after SLP. We may want to do that eventually, but I don't have a test case to support it yet. Differential Revision: https://reviews.llvm.org/D75145		2020-03-04 11:10:49 -05:00
