>> Clang 6.0 doesn't support LTO and PGO? > No, it appears not. That's really surprising. I see LTO mentioned in LLVM 3.4 changelog for example: https://releases.llvm.org/3.4/tools/clang/docs/ReleaseNotes.html#new-compiler-flags Did you try to build Python with my PR? Which error message do you get? How can I try? I only own a macbook which runs a recent macOS version. Maybe I could try to get clang 6.0 on Linux. If PGO is not available, just enabling LTO should already make Python faster significantly. I understand why Python is built on macOS 10.9, and this issue and my PR doesn't change anything about that. I don't request to require newer CPU features or to require newer macOS API or syscall. LTO only changes how Python itself is built. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41181> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
