As a part of our routine internal release testing we found out that the Ptrdist/yacr2 benchmark <https://github.com/llvm/llvm-test-suite/tree/main/MultiSource/Benchmarks/Ptrdist/yacr2> shows an around 10% regression after this commit on Haswell CPUs. It's not blocking us in any way, but you might be interested in confirming that this doesn't indicate an undesired side effect on the generated code.
