Bundles state that lives OUTSIDE the xenia-rs repo so a fresh clone on
another machine can be brought up to identical configuration via
migration/setup.sh:
- claude-memory/ ~/.claude/projects/-home-fabi-RE-Project-Sylpheed/memory/
(103 files, 1.1 MB - MEMORY.md + every
project_xenia_rs_*.md from audits
addis_signext through audit-058)
- project-root/dot-claude/ <project-root>/.claude/settings.json
(Stop hook + permissions)
- project-root/ppc-manual/ <project-root>/ppc-manual/
(PowerPC reference docs, 397 files, 3.7 MB)
- project-root/run-canary.sh <project-root>/run-canary.sh
- README.md Human-readable setup checklist
- setup.sh Idempotent installer (also reclones
xenia-canary at pinned HEAD 6de80dffe)
- MANIFEST.md Per-file mapping + per-file-not-bundled
restoration recipe
Excluded from bundle (not shippable via git):
- Sylpheed ISO (7.8 GB; copyright; manual copy required)
- sylpheed.db (395 MB; regenerable from XEX via analysis tooling)
- target/ build artifacts (rebuild on target)
- audit-runs probe firehoses (.log/.stdout/.stderr ~11 GB; rerun if needed)
- audit-runs memory dumps (.bin ~4.5 GB; rerun audit-026/027/029 if needed)
- xenia-canary checkout (setup.sh reclones from
git.mc02.dev/fabi/Xenia-Canary.git at HEAD 6de80dffe)

"""

Scrapes xenia-canary's emit files for the location of each instruction's
|
|
semantic implementation function `InstrEmit_<mnem>`.
|
|
|
|
The files are:
|
|
src/xenia/cpu/ppc/ppc_emit_alu.cc (integer ALU)
|
|
src/xenia/cpu/ppc/ppc_emit_memory.cc (loads/stores/cache/sync)

src/xenia/cpu/ppc/ppc_emit_altivec.cc (VMX + VMX128)
|
|
src/xenia/cpu/ppc/ppc_emit_fpu.cc (floating-point)
|
|
src/xenia/cpu/ppc/ppc_emit_control.cc (branch/CR/SPR/syscall/trap)
|
|
|
|
Returns, for each mnemonic, the relative file path and the starting line
|
|
of the `int InstrEmit_<mnem>(...)` definition.
