Those interested in profile-guided optimization may try a time-consuming process.

  1. Make instrumented package:
    • Set environment variable or edit PKGBUILD: _build_instrumented=true
    • Resulting package: pcsx2-instrumented-avx-git
  2. Create raw profiles using instrumented package.
    • LLVM_PROFILE_FILE="default_%9m.profraw" pcsx2-qt
    • Use a "representative" sample of roms.
    • After 9 runs, profraw files will be overwritten.
  3. Process profiles:
    • llvm-profdata merge -output=pcsx2-avx-git.profdata *.profraw
  4. Rebuild package.
    • Put pcsx2-avx-git.profdata in same folder with PKGBUILD.
    • Look for message: "Compiling with profile-guided optimization."
    • Profile can be reused. Re-profile when there are too many "function control flow change" warnings.
    • Resulting package: pcsx2-avx-git

This package targets x86-64-v3 instructions. Performance benefit over standard builds is minimal because of dynamic dispatch.

  • Avoid flagging and commenting at the same time for the same issue.
    • Flag for common issues with standard solutions, like submodule updates.
    • Comment for issues requiring explanation or debugging.
      • Use a pastebin for blocks of text more than a few lines.
