+/* func_8017D7CC @ ov_SC06_010 (subseg ov_SC06_010_jr_8017A4AC) — 87 ins.
+ *
+ * SEED: func_801822E0 @ ov_SC02_016 (src/ov_SC02_016/ov_SC02_016_jr_8017DC70.c), 91.9% skeleton-similar,
+ * already byte-matched. This is the near-identical sibling.
+ *
+ * Diff vs seed (byte-verified via objdump of the seed's matched .o):
+ *  - Seed uses an explicit `s32 i = 0; do { iVar1 = func_801824AC(); if (iVar1 >= 0) {...} i++; } while (i < 3);`
+ *    — a genuine do-while (no pre-loop guard), with the call's return value (iVar1) kept ONLY in $v1 (never
+ *    saved across calls) and a SEPARATE loop counter `i` in $s3.
+ *  - This target has NO separate counter: the loop variable IS the call's return value itself, tested both
+ *    for the if-guard (>=0) and for loop continuation (<3). Because that variable is reassigned only INSIDE
+ *    the loop body, the while-loop rotation ("if (cond) { preheader; do {...} while(cond); }") needs a
+ *    pre-loop guard test — but since the variable has no source-level initializer before the loop, the guard
+ *    reads whatever is in its (freshly register-allocated, never-yet-written) register: `slti $v0,$s2,3` /
+ *    `beqz $v0,<post-loop>` right after the buf[1]-=0x40 store, with NO assignment to $s2 anywhere before it.
+ *    Reproduced here as a genuinely uninitialized local tested by a `while` loop (matches gcc-2.7.2's
+ *    loop-rotation idiom exactly — the guard is emitted even though the variable's "value" is indeterminate).
+ *  - The `func_80146A6C(...)` calls' 7th argument is `1` here (not `0` as in the seed) — this constant is
+ *    loop-invariant and reused at BOTH call sites, so gcc hoists it once into a callee-saved register ($s4)
+ *    before the loop rather than re-materializing `li $a,1` at each site (the seed's constant is `0`, which
+ *    is free via $zero, so the seed needed no such register — hence the seed has one fewer saved S-register).
+ *  - The post-loop `if (cnt == 0) { ... }` here has NO else-branch (the seed's else called
+ *    `func_80172630((u8*)param_1)`); the asm falls straight from the 3-call if-body into the epilogue.
+ *  - Register roles differ naturally from the seed given the above (actor pointer ends up in $s3 here, not
+ *    $s2 — $s2 is claimed by the loop-return-value variable instead).
+ *
+ * Callee/global renames from the seed (per this TU's own asm ground truth):
+ *   func_801824AC -> func_8017D9A0   (still s32, no args)
+ *   func_80182434 -> func_8017D928   (still void, s32 a0)
+ *   func_80172630 -> (unused; no else-branch in this target)
