Thanks, that looks really nice. I see that my GCC 7 has -fdump-ipa-clones. It would be great if we could integrate that script's functionality with klp-convert somehow, such that it would warn if you're patching a function or a relocation which is affected. Or at least document how a human could do so. -- Josh
