The phi-of-ops functionality has a function OpIsSafeForPHIOfOps to determine when it's safe to create the new phi. But this function only checks for the obvious dominator conditions and ignores memory. This patch takes the conservative approach and disables phi-of-ops whenever there's a load that doesn't dominate the phi, as its value may be affected by a store inside the loop. This can be improved later to check aliasing between the load/stores. Fixes https://llvm.org/PR53277 Reviewed By: asbirlea Differential Revision: https://reviews.llvm.org/D117999 |
