Matches 24 small US functions (under 140 bytes) with no matching C yet: 7 in net.text, 1 in game, 16 in level overlays. 16 came straight out of the automatic m2c pass; 8 needed hand fixes. Two of them (func_01EC9060, func_01EC92E8) had drafts in nonmatching/net/; the drafts and their README rows are removed.

The batch was picked from functions nobody had tried, keeping only those m2c decompiles without errors (no syscall, VU0 or other instructions C cannot express here).

How they were matched

• 16 from the automatic pass (m2c draft, the usual clean-ups, then the compiler profiles): func_004B54D8, func_01EA76E8, func_01EC9060, func_01EC92E8, func_01EC94C0, func_01EC96C0, func_01EF03CC, func_01EF9844, func_L00_00513308, func_L00_005195A8, func_L00_0052FA40, func_L00_005463F8, func_L00_00547500, func_L00_00552380, func_L00_00714A80, func_L00_00717DF0. The net ones and func_L00_00513308 build with @ee296 -O2 -G0 -falign-jumps=1 (four of them with -mno-split-addresses), five l00_multiplayer_menu ones with @ee29 -O2 -G0, func_L00_00714A80 with -mno-split-addresses, and two need no cflags line.

• 8 fixed by hand:

  • u8 fields where retail uses lbu/sb (func_L00_00716828, func_L00_00748B20, func_L01_004D90B0);
  • a pointer step m2c scaled by the element size (func_L08_004B8018: 4 bytes, not 16);
  • five arguments where m2c saw four (func_L00_005192C0, func_L00_00528568: retail sets $t0);
  • the flags field read again instead of a cached copy (func_L00_00520548);
  • the array base computed before the index, and the callee declared without parameters: retail's $a1 is only the scaled index (func_L01_00466040).

  Profiles: func_L00_00520548, func_L00_005192C0 and func_L00_00528568 build with @ee29, like their neighbours in l00_multiplayer_menu; the other five need no cflags line.

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

Verification

On main at 4a7372f:

• full tools/build.sh, build_libgcc.sh, build_libm.sh;
• tools/audit_matches.py and tools/audit_relocs.py: no line names any of these functions;
• config/{us,pal}/map.tsv changed only on these rows (match_map --write with and without the new files, applied as a delta), then match_map --check;
• progress.py --check for US and PAL: US 7,163 → 7,187 and PAL 7,644 → 7,667.

Independent of #128 and #130 (no file in common).

Left out: func_0013A0F0 also matches in US, but src/pal/core/0013A0F0.c defines the same symbol with the PAL addresses, and audit_relocs.py checks every object in build/obj/ against the US addresses once the name is exact in US, so the PAL object shows up as 4 mismatches. That looks like a tool issue (the PAL objects should be skipped in the US check), so I kept the function out of this PR.

Reserved in #112.
