- CRACK (cheap Opus, no Fable5/calls.c): the 770-ins reach-134 whale's 2-insn residual was a
STRUCT ASSIGN `D_80078E50 = *ent;` (sizeof(ENT)==0x24), NOT an explicit memcpy() call — gcc-2.7.2
-O0 expands a >MOVE_RATIO-word struct copy via emit_block_move->emit_library_call(memcpy),
precomputing dst/src into pseudos then addu into $a0/$a1 = the exact 2 missing moves.
- -O0 SPLIT: whale is a 2nd -O0 region (prologue 21F0A003) in the -O2 'after' segment; carved into
its own -O0 object o0b (splat.ov_SC01_077.yaml 3-way + Makefile CC1FLAGS=-O0; address-sorted
line-split preserves all banked C). ov_SC01_077 == d19c9580.
- memcpy: memcpy=0x8005C324 in symbols.resident.txt (overlays+resident only; main untouched vs its
MEMCPY.o) + __asm__("memcpy") on the engine_core.h block-copy macro (non-builtin C name -> no
built-in codegen, same call).
- MILESTONE: CLEAN fleet check-all 136/136 byte-identical (R22), dedup 1810/0. reach-134 -> ×134 (W9) next.
