The user-requested async overlay tiering (interp-now / compile-async / native-next, gcc-if-present
else sljit, always async, file-based handoff) is LARGELY ALREADY IMPLEMENTED — overlay_capture.c
(autocapture on interp pressure) + autocompile.c (background compile via a configured command,
toolchain-probed, watcher thread, file-based) + the code_provider abstraction. It just needed
CPS wiring.
This commit:
- overlay_loader_apply_live_policy: when the active backend is gcc, force sljit-live OFF so a gcc
box is gcc>interp (NOT the previous complementary gcc+sljit). Toolchain-less boxes stay
sljit>interp. PSX_OVERLAY_SLJIT_LIVE still overrides. ("mutually exclusive" per user.)
- ASYNC_OVERLAY_COMPILE.md: re-headed to reflect the feature is built+validated under CPS, with
the deltas this session added (compile_overlays --cps from §25.5, the gcc-only policy, the
dev-config overlay_autocompile_cmd --cps).
VALIDATED under CPS: autocapture fires -> background compile_overlays --cps produces CPS overlay
DLLs -> loader loads them -> dispatch_native rises; gcc box shows 0 sljit shards; ce_profile flat.
The native overlay cache auto-builds as you play (each scene compiles on its first sustained
visit). PRODUCTION game.toml overlay_autocompile_cmd still needs --cps appended when CPS ships.
