[Tomas Matheson via Phabricator via llvm-commits]

tmatheson added a comment.

The same problem exists in the ARM backend, which I fixed internally by implementing new pseudos for the atomicrmw instructions, but hadn't got round to upstreaming it yet. Here it is for comparison: D101164 <https://reviews.llvm.org/D101164>.
