[PATCH] D58632: [X86] Improve lowering of idemptotent RMW operations

[Sam McCall via Phabricator via llvm-commits]

It reduces to this point with the same error: F8862002: bugpoint-reduced-simplifycfg.ll <https://reviews.llvm.org/F8862002>

Bugpoint can reduce it further, but to a segfault that I'm not sure is the same error (--append-exit-code doesn't seem to help me): F8862000: bugpoint-reduced-simplified.ll <https://reviews.llvm.org/F8862000>
