Thanks for clarifying! The regression seems like an X86 backend issue, unrelated directly to tail duplication for computed gotos. Given that there is no (or a very small) end-to-end regression, I think the change should be included in the release, or an argument should be made for reverting/adjusting https://github.com/llvm/llvm-project/pull/150911 (the version of the PR landed on `main`) https://github.com/llvm/llvm-project/pull/151680 _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
