As others mentioned, LTO will be contained to a specific package build. Allowing Clang can also *improve* LTO. Specifically, Firefox has a mix of C++ (could use GCC or Clang) and Rust (always LLVM). With Clang, they'd have an all-LLVM build, and could enable cross-language LTO: http://blog.llvm.org/2019/09/closing-gap-cross-language-lto-between.html _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
