I agree. But when moving the code llvm thinks it is something cheap, and its is not, which is also a performance problem. Things would be much easier if we could tell an instruction belongs to a WWM region. https://github.com/llvm/llvm-project/pull/123124 _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
