NewGVN tables are not cleared out between the initial run of NewGVN and the verification. In case of phi-of-ops optimization, OpSafeForPHIOfOps goes out of sync between the two runs. One operand might not be safe for one basic block, but it might be safe for one of its successors. In this case, the operand will be added in OpSafeForPHIOfOps map. In verification phase, we reuse OpSafeForPHIOfOps without updating it again. As a result, the operand will be considered safe for phi-of-ops optimization even for the case that it is not. This patch fixes this problem. Fix for 53807. Reviewed By: asbirlea Differential Revision: https://reviews.llvm.org/D130910 |
