- mapped the blob vs bytes: word0 data header (0x36); clean code 0x4..0x4610 (145 funcs, zero embedded jump-tables/trap-ops); data tail 0x4610..EOF (pointer tables + 78.5KB zeros) - split: [0x0, rodata, hdr] + [0x4, c, resident] + [0x4610, data, tail] - fix 1: the leading data word sits BEFORE code, which fights section_order; emit it as rodata (no-dot) so section_order [.rodata,.text,.data,.bss] places it first @0x800CEDF8 — a 1-word analogue of main's rodata-island, no ld_interleave needed - fix 2: build_path=build (not build/resident) so splat's .ld object paths match the Makefile's build/asm/** + build/src/** pattern rules (only elf/ld/output in build/resident/) - MILESTONE: make build BINARY=resident -> 8e17e02ff8954d07c979449198f7e1645046b353 BYTE-IDENTICAL (365,404 B, end vram 0x80128154); -G0 confirmed (0 gp refs); R22 clean-rebuild green; main still 143dbb89… (no regression) - src/resident/resident.c (143 INCLUDE_ASM stubs) committed; asm/resident/** regenerated

# splat config — Brave Fencer Musashi resident engine blob (MAIN.CD/FILE_010/1.1)
|
|
# Phase 10: rebuild the always-resident engine blob byte-for-byte from disassembly
|
|
# (100% INCLUDE_ASM), as the project's SECOND build binary (alias `resident`).
|
|
#
|
|
# Mirrors config/splat.us.exe.yaml's PSX options (compiler PSYQ, subalign 2,
|
|
# section_order rodata/text/data/bss, find_file_boundaries False) but for a FLAT
|
|
# decompressed blob:
|
|
# - NO header segment (not a PS-X EXE; first word is data 0x00000036, code at +0x04)
|
|
# - NO gp_value (-G0 like the EXE — verify zero ($gp) refs in the disasm, T2)
|
|
# - single code segment @ vram 0x800CEDF8 (load address RAM-proven, Phase 3 T6b)
|
|
# - output nested under asm/resident + src/resident + build/resident (per-binary, so
|
|
# the Makefile OBJS glob keeps it disjoint from main's asm/ + src/)
|
|
# - per-binary undefined_*_auto paths (under build/resident/) so main's stay verbatim
|
|
# - stacked symbols: config/symbols.us.txt (the 27 shared engine globals the blob
|
|
# references) + config/symbols.resident.txt (blob-local, R13/R15-tagged)
|
|
#

# Boundaries: 365,404 B (0x5935C) -> end vram 0x80128154 (4 B under the location-overlay
|
|
# slot 0x80128158). The text/data split is ITERATED against `make check BINARY=resident`
|
|
# in Phase-10 T2 (the Phase-5 precedent); this scaffold starts as one code subsegment.
