See this comment: https://github.com/llvm/llvm-project/issues/97466#issuecomment-2211752286

To share the code would be more work than I currently have time to do. My goal was to try to fix immediate flang crash issue for x86. (ARM doesn't crash for invalid CPU, but it does something different.) Perhaps we can fix x86 now and file a new "feature" issue for trying to get some code re-use in flang and clang?
