Split-TU: extract JitPowIntegerEmitExponents50to69 (#36387) - #37649
Merged
Conversation
Move compile-time integer ** exponents 50–69 (~16k lines of chained-smul) out of JitPowIntegerEmit so gen-0 spine gets a TU between Mid (30–49) and High (70+). Hub shrinks to a 107-line dispatcher. No behavior change; no new C ABI. Co-authored-by: Cursor <cursoragent@cursor.com>

…37651) Mirror Low/Mid/High — null compile-time fold (runtime exponent) must fall through to MathFpow, not TypeError on the string param. Without this, `pow($n, $runtime_var)` crashes under AOT when the hub dispatches to this TU. Low (1–29), Mid (30–49) and High (70+) already have the guard; Exponents50to69 was extracted without it in #37649.
