In D110057 we moved LoopFlatten to a LoopPassManager. This caused a performance regression for our 64-bit targets (the 32-bit were unaffected), the pass is no longer triggering for a motivating example. The reason is that the IR is just very different than expected; we try to match loop statements and particular uses of induction variables. The easiest is to just move LoopFlatten to a place in the pipeline where the IR is as expected, which is just before IndVarSimplify. This means we move it from LPM2 to LPM1, so that it actually runs just a bit earlier from where it was running before. IndVarSimplify is responsible for significant rewrites that are difficult to "look through" in LoopFlatten. Differential Revision: https://reviews.llvm.org/D116612 |
