================ Comment at: llvm/test/CodeGen/X86/O3-pipeline.ll:147 +; CHECK-NEXT: X86 Load Value Injection (LVI) Load Hardening ; CHECK-NEXT: Fixup Statepoint Caller Saved ; CHECK-NEXT: PostRA Machine Sink ---------------- I'm curious what happens if we add AU.setPreservesCFG() to getAnalysisUsage in FixupStatepointCallerSaved.cpp From a quick look through that pass it doesn't look like it changes the Machine CFG. PostRA Machine Sink already preserves CFG. So I think that should remove the dominator tree construction after PostRA machine sink.
