Valiantsin DzerakhandClaude Opus 5.5 282130a128 Build the game code with an execution profile when the release has one ...

build_game.py --pgo gen builds an instrumented totk.exe (llvm-mingw: MSYS2's clang has no profile runtime) that adds
its counts to <out>/pgo/*.profraw every minute and at exit; plat_exit ends the process with ExitProcess, which skips
compiler-rt's atexit write. tools/pgo.py merges them into build/pgo/pgo-<ver>.profdata with a record of the recomp/
tree it fits. build_game.py --pgo FILE compiles the generated code at -O2 and the runtime with that profile.

make_release.py ships build/pgo's profiles in data/ and builds the runtime libraries with them; the installer passes
the update's profile to build_game.py, and builds at -O1 without one. Profiles name lifted functions by address and
hold branch counts and control-flow hashes of the generated C, no bytes of the game.

1.4.3 on machine A, mean frame by world clock: the fight2 bench 11.49 -> 10.06 ms (-12.5%), a fight outside the
training 13.00 -> 12.24 ms (-5.8%); every window CPU-bound. The profile was trained on scripted runs and 24 minutes
of play.
