Adds [[input.decompressed_section]] toml block + Yay0/PERS-SZP wrapper
decoders + an in-memory section synthesis pass. Required for games
like Pokemon Stadium where Stadium's CPU-side decompressor materializes
fragment bytes at runtime and the static recompiler can't see them in
the ELF/ROM-direct path.
User-facing config:
[[input.decompressed_section]]
name = "fragment78"
vram = 0x8FF00000
rom_wrapper = 0x9E93F0
wrapper_format = "pers_szp_yay0"
Pipeline:
1. compression/{yay0,pers_szp}.{h,cpp} decode the wrapper.
2. decompressed.cpp parses the FRAGMENT-format header (relocOffset,
sizeInRam) + Stadium-format reloc table, translates it to
N64Recomp::Reloc entries (R_MIPS_32/26/HI16/LO16) with paired
HI16/LO16 immediate computation, and synthesizes a Section
handed to the existing recompilation pipeline. Stores
decompressed bytes into context.rom at synthetic_rom =
0xFE000000 | rom_wrapper to keep them out of real-ROM addr space.
3. Two functions per fragment: the +0x00 entry trampoline (J + nop)
and the +0x20 implementation (runs to first jr ra in body).
4. After all decompressed sections are added, retargets each
R_MIPS_32 reloc to whichever existing section's vram range
contains its target address (cross-section pointer support).
Adds [output] collision_policy:
"error" (default) — abort the build if two emitted symbols collide
on name; print both colliders + how to opt in.
"suffix" — auto-disambiguate by appending __rom_<rom_addr>
to colliding symbols. Suffix only appears where
collisions exist.
Validated end-to-end on Stadium's fragment78 (wrapper at ROM 0x9E93F0,
decomp_size=0x25340, 319 relocs). Recompiled func_8FF00020 dispatches
to runtime_addr+0x24DC0 correctly; Stadium boots past the prior
crash point, no regression on the N64 logo + PIKA jingle.
Future work: pattern form ([[input.decompressed_section_pattern]]) for
slots like vram 0x8FF00000 where Stadium streams 279 different
fragments at the same link addr. Validation script
(tools/_validate_dynfrag.py in the consumer repo) confirms 268 distinct
content-hashes, 23MB total payload — feasible as engine work.
