The tier mis-compiled and has been hard-gated off since 2026-06-25; overlay
gaps fall to gcc/tcc shards and the dirty-RAM interpreter, unchanged.
Re-do on master of the removal validated on the stale branch (6da8c02),
reconciled with everything master grew since the fork:
- Delete overlay_sljit.{c,h}, overlay_compile_worker.{c,h}, lib/sljit,
runtime/tests/sljit_*.c, and the runtime.cmake sources/include-dirs.
- Strip the sljit provider/backend from code_provider.{c,h},
overlay_backend.{c,h} ("sljit" in overlay_backend/PSX_OVERLAY_BACKEND now
degrades to auto so stale configs still boot), main.cpp, debug_server.c
(sljit_status/sljit_async/sljit_try TCP commands), overlay_loader.{c,h}
(live policy, JIT-on-miss, persisted-shard cache, async worker glue,
psx_sljit_call/cop2/memx host helpers — reachable only via the removed
cpu->sljit_helpers table), and cpu_state.h (SLJIT_HLP_* enum + the
sljit_helpers[] member; CPUState layout change reshards via the cg tag).
- Master-only entanglement resolved before deletion: 28165d6's Einhander WS
player-X bound emit existed in three paths (gcc code_generator, sljit,
dirty_ram_interp). The gcc shard link contract now forwards
psx_ws_player_x_bound (ABI v13, previous commit), so deleting the sljit
emit path loses no widescreen behavior; ffc6688's game-dispatch block
inside the dead psx_sljit_call helper goes with it.
- Reword comments that described sljit as a live backend (gpu.{c,h},
ws_*_detect.h, cosim_state.c, dirty_ram_interp.c, autocompile.h,
boot_state.h, config_loader.h, compile_overlays.py, and the CPS marker
comments the recompiler emits).
recompiler psxrecomp-game builds clean; game runtimes rebuilt + boot-verified
separately.

/* code_provider.h — the backend-agnostic code-production seam.
|
|
*
|
|
* One interface the overlay capture/dispatch spine talks to instead of calling
|
|
* a specific backend directly. The validated gcc/tcc spawn->DLL->rescan path is
|
|
* its implementation. Everything that makes overlays correct — content-keyed
|
|
* multi-candidate dispatch, per-call live-byte validation, the self-mod
|
|
* blacklist, the coverage manifest — is backend-blind.
|
|
*
|
|
* Production is BATCH / ASYNC (request / busy / poll_main): kicked by the
|
|
* autocapture tick, spawns a compiler off-thread, applied later via a cache
|
|
* rescan on the emu thread. Seconds of latency; many fragments per run. A
|
|
* provider sets the hooks it supports and leaves the rest NULL; callers
|
|
* null-check before invoking.
|
|
*
|
|
* (The in-process sljit JIT provider — a synchronous on-miss producer with a
|
|
* compile_fragment hook — was removed 2026-07-15; it had been disabled by
|
|
* default since 2026-06-25 due to an emitter bug. Gaps gcc/tcc have not yet
|
|
* covered fall to the interpreter, the always-safe precision-over-recall floor.)
