Both batch targets are met in one pass: 22 new bodies (23 including the P7-T5
match), taking the project from 11 distinct bodies to 34 -- past the phase
milestone of 30 -- across 39 registered regions.
The batch is dominated by the small leaf shapes the worklist ranks first:
empty function (4 duplicate addresses), byte/halfword/word setters, field
getters, a word-buffer clearer, and eight gp-relative getters/setters. Every one
was byte-identical on the first or second attempt, and every extent came from
tools/sf3_extents rather than a hand-derived end.
Three shapes needed diagnosis, and two were solved:
- 0x8003636C was 16 bytes instead of 12 because `return 1` forced a second
`li v0,1` into the delay slot; the original leaves 1 in v0 as scratch, so the
function is `void`.
- 0x800F7FB4 needed the parameter reused as the loop counter.
Four candidates are recorded as bounded negatives or deferrals rather than
guesses:
- 0x800F7FB4: the loop body reproduces exactly, but the original has no frame
and every tested formulation allocates 8 bytes (five C forms, and an
-O1/-O2/-O3/-fomit-frame-pointer matrix). Stopped after two distinct attempts.
- 0x800F8AEC: the original schedules `lui` / `jr ra` / `addiu` with the low half
in the delay slot; the reconstruction emits `lui` / `addiu` / `jr ra` / `nop`.
- 0x80010810: GTE (COP2) code needing the SDK's GTE macros, which the build has
no headers for.
- 0x800FB5D4 (`move v0,sp`) and 0x80103FCC/0x80103FEC (BIOS `syscall` wrappers)
and 0x8001EAFC (a shared jump block, not a standalone function).
make gate: c_regions=39, 0 differing bytes, SHA-1 e173426c. Extents verify agrees
on all 39 regions. 168 synthetic tests.
