Thanks Ned, this is interesting!
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. |
