Thanks! @lukel97 @dyung I think this should be included in the 21.x release because this fixes a miscompile (https://github.com/llvm/llvm-project/issues/169905) which existed since LLVM 20.x. If we don't fix it in 21.x, we will have two releases that have this problem. The diffs look large because the candidate registers of `vmerge` instructions have changed, which results in different register allocation results. We have tested llvm-testsuite with this PR and there is no correctness issue. https://github.com/llvm/llvm-project/pull/170604 _______________________________________________ llvm-branch-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
