+ * func_800B0E64 — 104 bytes at 0x800B0E64..0x800B0ECC
+ *
+ * Four zero-fills of fixed-size regions, then one gp-resident word cleared. First spelling.
+ *
+ *     addiu sp,sp,-0x18 / sw ra,16(sp)   frame 24: ra at 0x10, no other saved register, so
+ *                                        nothing is live across the four calls.
+ *     lui a0,0x8014 / addiu a0,a0,-14884 0x8013C5DC, materialised as a SYMBOL (addiu, not
+ *                                        ori -- cookbook 89).  The first a0 is built BEFORE
+ *                                        the ra save; the later ones after each call returns.
+ *     move a1,zero                       the fill value is 0 ...
+ *     jal 0x800266A8 / li a2,6864        ... and the size is the call's delay slot.
+ *     ... x3 with 176 and 8624 bytes at 0x8013E0AC and 0x8013E15C
+ *     addiu a0,gp,3568                   the FOURTH target is `gp`+-relative -- one
+ *                                        instruction, not a lui/addiu pair.  gp is 0x80121938,
+ *                                        so this is 0x80122728, an already-registered gp symbol.
+ *     jal 0x800266A8 / li a2,4
+ *     sw zero,1768(gp)                   the tail clears the gp-resident word at 0x80122020.
+ *
+ * The four calls differ only in destination and size, and the sizes (6864 / 176 / 8624 / 4) are
+ * taken straight from the `li` immediates. All four go to the same callee, so the argument shape
+ * is paid once: (destination, 0, size) with the size in the jump delay slot every time.
+ *
+ * The address forms are the one byte-bearing choice here, and they are NOT uniform:
+ *   * the first three are ABSOLUTE (`lui 0x8014` + `addiu`), so their symbols carry no gp marker;
+ *   * the fourth is `gp`+-relative (`addiu a0,gp,3568`), which needs the symbol to be gp-marked
+ *     in the registry -- an `&symbol` whose marker is absent silently resolves absolutely and
+ *     costs the extra `lui` (cookbook 30's name-keyed-gp trap, cookbook 46).
+ *
+ * LIMITS: func_800266A8 is a cross-reference by address only; the (dest, value, size) reading is
+ * from the emitted argument registers and the delay-slot `li`, not from a recovered prototype.
+ * `D_8013C5DC` / `D_8013E0AC` / `D_8013E15C` are address symbols (name == address, so they need
+ * no registry row) declared as `char[]` to make them pass as addresses; the true object types and
+ * sizes are not recovered -- only the three sizes the source passes. `D_80122728` and
+ * `D_80122020` are the already-registered gp-marked globals at gp+3568 and gp+1768.
