================
Comment at: llvm/test/CodeGen/X86/atomic-rm-bit-test-64.ll:1474
%0 = atomicrmw xor ptr %v, i64 16 monotonic, align 8
- %and = and i64 %0, 16
+ %and = and i64 16, %0
%tobool.not = icmp eq i64 %and, 0
----------------
I'd expect DAG canonicalization to commute this in DAGCombiner::visitAND?
