In most cases we do not set debug locs on PHI nodes or expect them to have debug locs, but there are some cases where we explicitly set/check them - most often in loop optimizations, where PHIs may have source locations relevant to the loop induction variable, and in InstCombine where we perform transformations between ordinary instructions and PHIs. I don't _think_ we have a well-defined policy in place, but since they're sometimes useful it's a good rule-of-thumb to propagate them if doing so makes sense. https://github.com/llvm/llvm-project/pull/133492 _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
