I don't know about Mac OS, but on Ubuntu, LTO and PGO apparently make Python around 10% faster (see #17781). However, that data point refers to GCC's LTO, not LLVM's. Personally I'm interested in LTO because I want to obtain whole-program LLVM bitcode files (for use in a research project about instrumentation). However, if there is something I can help (e.g., running benchmarks with different compilation settings), let me know. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21122> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
