CONSOLIDATION.md Phase 6. Both lived untracked in the project root -- on one
disk, backed up by nothing.
tools/ppc-manual/ 393 files, 3.7 MB. 455 instructions, 350 family pages,
598 mnemonics resolvable through index.json, plus the
generator that produced them.
tools/run-canary.sh the oracle launcher.
🔴 THE LAUNCHER WAS BROKEN IN TWO WAYS AND IS REWRITTEN, not copied:
* it pointed at `xenia-rs/sylpheed.iso`, a SYMLINK. Wine cannot resolve one
and says "path invalid", which reads as a corrupt image rather than a path
problem -- it has cost a session before. It now points at the real file and
warns if handed a symlink.
* it hardcoded one machine's absolute paths, and named `xenia-rs`, which this
consolidation retires. Now derived from the script's own location, with
SYLPH_CANARY_BIN / SYLPH_ISO overrides and a check that each exists.
The standing constraints are in its header where someone will read them: one
emulator at a time, Canary runs MUTED, and never judge a crash or a hang from
a Bash-launched run -- a SIGKILL that looked like the binary was the editor's
process supervisor.
⚠️ The manual's GENERATOR reads the xenia-rs source tree, which is going away.
Its decoder now lives here as crates/sylpheed-ppc, so the generator must be
repointed before it is run again. Recorded in the README rather than left for
someone to discover; the manual's content is checked in and regenerates from
nothing implicitly.

# Form `VC` — VC — Vector Compare (with Rc → CR6)
|
||
|
||
## Bit Layout
|
||
|
||
| Bits | Field | Meaning |
|
||
| --- | --- | --- |
|
||
| 0–5 | `OPCD` | primary opcode (4) |
|
||
| 6–10 | `VRT` | destination vector register |
|
||
| 11–15 | `VRA` | source A |
|
||
| 16–20 | `VRB` | source B |
|
||
| 21 | `Rc` | record-form flag (updates CR6) |
|
||
| 22–31 | `XO` | extended opcode (10 bits) |
|
||
|
