Emitter side of the value-propagation engine (ENHANCEMENTS.md G1.10):
- recompiler/src/pgxp_hook_emitter.{h,cpp} (new, in the codegen-hash
surface): ONE hook grammar shared by BOTH emitters, wrapping loads/
stores/COP2 transfers and precision-carrying ALU ops (moves, add/sub,
or-merge, shifts, LUI, HI/LO, muldiv) with PGXP_*() macros. Clobberable
sources are captured into locals before the statement. Precision-
destroying ops (AND/XOR/SLT/...) are deliberately unhooked - validate-
on-read drops their stale shadows for free.
- code_generator.cpp: central append in translate_instruction; LWC2/SWC2
emissions capture the RAW loaded/stored word (a masked GTE register
write must validate against the word as loaded).
- strict_translator.cpp: translate() wraps translate_impl()'s c_code with
the shared grammar; deferred load-delay variants hook the psx_ldd temp.
- BIOS regenerated, fingerprints verified CHANGED (SCPH1001 + OpenBIOS;
42.6k/12.2k macro sites). Base runtime + 33/33 tests green against it.
- Gating: macros expand only under -DPSX_PGXP=1. runtime.cmake grows a
PGXP option on psxrecomp_add_runtime_target (defines PSX_PGXP=1 +
PSX_OVERLAY_FLAVOR=2, _pgxp exe suffix) and PSX_PGXP_VARIANT to build
the sibling target from the same generated tree (framework runtime +
game wrapper). No ABI version bump needed: the appended PGXPHooks
table is NULL-tolerant and the flavor half of the ABI tag rejects any
host/DLL flavor mix.
- Shard caches: flavor folded into the cache tag (cg<V>_<hash>_gc<hash>
_f<flavor>) in overlay_loader.c + compile_overlays.py so base and pgxp
caches never share a directory; compile_overlays.py passes
-DPSX_PGXP=1 when flavor bit 2 is set; overlay preamble forwards
psx_pgxp_* through the table. PSX_OVERLAY_CODEGEN_VER 9 -> 10.
- Env overrides PSX_GEOMETRY_CORRECTION / PSX_PERSPECTIVE_TEXTURING /
PSX_PGXP_CPU_MODE (validation path: free-running headless boots arm
from the first vertex); census grew produced/swc2_stores and the pgxp
verb reports suppress/active gate state.
Validated: PSXRecomp_pgxp.exe boots the recompiled BIOS with hooks armed
(engine active, per-vertex lookups flowing; the BIOS shell has no RTPS
content so produced=0 there is correct - coverage measurement moves to a
3D title in phase 3).

# codegen_hash_sources.cmake — the CANONICAL list of recompiler codegen sources
|
|
# folded into the overlay cache tag hash (hash_codegen.cmake).
|
|
#
|
|
# Included from BOTH:
|
|
# - runtime/runtime.cmake (bakes the hash into the runtime's cg tag)
|
|
# - recompiler/CMakeLists.txt (bakes the SAME hash into psxrecomp-game,
|
|
# exposed via `--codegen-hash`)
|
|
# so the two hash computations can never drift by list divergence. Any file
|
|
# added to the emitter pipeline must be added HERE, once.
|
|
#
|
|
# Input: PSXRECOMP_CODEGEN_HASH_ROOT — the psxrecomp repo root.
|
|
# Output: PSXRECOMP_CODEGEN_HASH_SRCS — absolute paths to hash.
|
|
|
|
# NOTE: include the emitter .cpp translation units, not just their headers. A
|
|
# change confined to full_function_emitter.cpp (e.g. the 2026-07-03 Class-A
|
|
# shell-window overlay-dispatch fix) alters both generated dispatch and overlay
|
|
# code but left the hash unchanged when only the .h files were listed — a stale
|
|
# overlay-cache hazard (same class as the "ws emission not in cg hash" gap).

# --- Shard COMPILE surface -------------------------------------------------
|
|
# The cg tag must invalidate on anything a shard compiles/links against, not
|
|
# just what the emitter WRITES. A change to the overlay ABI header, the
|
|
# CPUState layout, or the dispatch-shim link contract leaves the emitter
|
|
# sources untouched — so without these the tag stayed put, existing DLLs kept
|
|
# loading, and every NEW shard silently failed to compile against the moved-on
|
|
# runtime (the recurring "header change broke the shards" class). Folding the
|
|
# compile surface in makes such a change reshard SAME-TREE instead of breaking
|
|
# silently. overlay_api.h pulls cpu_state.h and its cycle-helper headers; the
|
|
# .inc is the shim every shard links against.
