[GarfTornion]

Matches 26 US functions of reservation batch 52: 4 in net.text, 6 in game, 2 in core, and 14 in overlays (7 l00_multiplayer_menu, 7 shared/L11/L15). All are small (16-128 bytes). The first commit also stages 24 near misses in nonmatching/ with their measured verdicts; three are updated by later commits.

func_01EACEF0, func_01EB4DD0, func_01EA8BD0, func_01EDA958 (net); func_00547DC8, func_00547E00, func_00548040, func_00548078, func_00548DA0, func_00501988 (game); func_00154010, func_0012E8C8 (core); func_L00_00519CF0, func_L00_00709290, func_L00_00709980, func_L00_00710750, func_L00_00753158, func_L00_007099A0, func_L00_0077A2F8 (l00 overlay); func_L01_003C90CC, func_L01_0043C180, func_L01_0048AD68, func_L01_004BDD78, func_L01_00573B60, func_L11_003C5088, func_L15_004E38C4 (shared overlays).

How they were matched

• 9 from m2c plus flag/compiler sweeps: func_01EACEF0 (@ee296 -O2 -G0), func_L11_003C5088 (-fno-schedule-insns -fno-schedule-insns2), and func_01EB4DD0, func_L00_00519CF0, func_L00_00709290, func_L00_00709980, func_L00_00753158, func_L01_003C90CC, func_L15_004E38C4 from their drafts.
• 6, four of them through the permuter: the 0x44-stride accessor family func_00547DC8, func_00547E00, func_00548040, func_00548078 (C written as T *p = &param; on a clamped index, which is what the allocator needs), plus func_00154010 (@ee296 -O2 -G0 with a u32 counter for sltiu) and func_L00_00710750 (store order).
• 3 from a hint or a matched neighbour: func_00548DA0 (permuter hint rewritten as plain C), func_01EA8BD0 (the 16-byte argument slots turned out to be the 8-byte-aggregate ABI of src/net/01EB4DE8.c, and the handler is read as a struct member), func_L01_0043C180.
• 4 from statement order and the hazard-nop compiler: func_01EDA958 and func_00501988 build with @ee296 -O2 -G8, the only compiler that emits the R5900 sllv/div.s latency nops retail carries (-G0 moves the globals off $gp and does not match); func_01EDA958 also needs a u32 counter copied from its u16 parameter, otherwise GCC re-truncates inside the loop. func_L00_007099A0 is a statement order (the unconditional store before the final if), func_L00_0077A2F8 a store order (the pairwise reverse of retail's).
• 4 from C-shape rules: func_L01_004BDD78 (comparing the masked value signedly blocks GCC's single-bit sra+andi fold), func_0012E8C8 (the function returns 0 - retail's daddu $v0,$zero,$zero - and the tail written as an array index keeps %hi in a register; @ee29 -O2 -G0 like its neighbours), func_L01_00573B60 (a mode(TI) 16-byte copy), func_L01_0048AD68 (u128 tmp[1] homes a TImode local on the stack, which a scalar does not).

No #define aliases, volatile, inline asm or hard-coded addresses.

Verification

upstream/main at 0bddadfd is merged in (the merge commit regenerates the derived files), and the branch tip is 6672aa1a:

• full tools/build.sh: 8,414 objects;
• tools/audit_matches.py: 5,650 exact, 164 pre-existing non-exact; no line names any of the 26;
• tools/audit_relocs.py: 27 records and no unresolved target, none of them ours;
• config/us/map.tsv 7,741 match, config/pal/map.tsv 8,327 match;
• tools/progress.py --check for US and PAL: US 7,695 of 18,170 functions / 745,840 of 5,781,432 bytes (12.90%), PAL 8,062 of 18,134 / 850,424 of 5,810,856 (14.64%).

Reserved in #112. Independent of #121 and #137 (no file in common).

The remaining 24 functions of the reservation stay in nonmatching/ with their measurements: 6 are not functions (four catalogue fragments, a shared entry point and a hardware-register routine), 10 are closed by measured compiler or layout behaviour, and 8 are one register-allocation choice away from exact.
