If the convention expects the caller to preserve its LR, then LR is never live out of the call. If the callee restores the LR to the value before the call (e.g. by popping it from the stack), then LR is a live-out.
I haven't looked at the updated testcases in detail, but I see that most of the changes are in treating LR as live (whereas it was dead before). At the first glance that doesn't look right. https://github.com/llvm/llvm-project/pull/73553 _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
