Add a quick loop to clean these up afterwards if we can getaway with modifying an existing compare instruction instead.(StructurizeCFG is generally run late in the pipeline so instcombinedoes not clean them up for us.)Differential Revision: https://reviews.llvm.org/D118623 List of files: /llvm-project-15.0.7/llvm/test/Transforms/StructurizeCFG/bug36015.ll Mon, 31 Jan 2022 16:56:32 +0000 Jay Foad <jay.foad@amd.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/Transforms/StructurizeCFG/bug36015.ll#8faad296 Revert "[Local] invertCondition: try modifying an existing ICmpInst"This reverts commit a6b54ddaba2d5dc0f72dcc4591c92b9544eb0016.Apparently it is not safe to modify the condition even if it passes thehasOneUse test, because StructurizeCFG might have other references tothe condition that are not manifest in the IR use-def chains.
