CONSOLIDATION.md Phase 2. Each of these existed only in a repository about to
be retired, or as an untracked file on one disk -- which, for anything that
has to survive a machine, is the same as not existing.
xex2-format.md 39 KB the XEX2 container format

The first two are byte-identical to xex2tractor's copies, verified with cmp,
and byte-identical again to the loose untracked copies in the project root:
three copies, zero of them tracked.
docs/reference/ is deliberately its own directory with a README that says
what it is NOT: nothing here is a finding, and no docs/re/ page should cite it
as evidence. Reference material filed beside measurements is how a borrowed
table starts getting read as a result.

# Xenia Canary — PowerPC Instruction Reference
|
|
|
|
Complete catalog of all **455 PowerPC instructions** implemented in the Xenia (canary)
|
|
Xbox 360 emulator. These instructions are defined in `tools/ppc-instructions.xml` and
|
|
code-generated into the emitter/decoder/disassembler pipeline.
|
|
|
|
## Architecture Overview
|
|
|
|
```
|
|
PPC Binary → Decoder (ppc_opcode_lookup_gen.cc)
|
|
→ Frontend Emit (ppc_emit_*.cc) → HIR (intermediate representation)
|
|
→ Backend Sequences (x64_seq_*.cc / a64_seq_*.cc) → Host Machine Code
|
|
```
|
|
|
|
