    M llvm/lib/Transforms/InstCombine/InstCombineAddSub.cpp
    M llvm/test/Transforms/InstCombine/sub-xor.ll
    M llvm/test/Transforms/PhaseOrdering/X86/pr88239.ll

  Log Message:
  -----------
  [InstCombine] Don't use dominating conditions to transform sub into xor. (#88566)

Other passes are unable to reverse this transform if we use dominating
conditions.
    
Fixes #88239.
