Head commit for run: d239d9be4b5a60740f2bbb38ca7f4cdac054c321 / tqchen <[email protected]> [FEAT] BigInt support for arbitrary-precision integer value This PR adds a canonical arbitrary-precision integer value with an inline int64 fast path and one variable-length object for larger values. BigInt is a tagged union that stores either an int64_t or a BigIntObj containing a dynamically sized array of 64-bit words. Key design details include: - Arithmetic automatically promotes to higher precision when needed, preserving integer results without overflow. - Storage is canonical: values that fit in int64_t are always stored inline, and BigIntObj never contains redundant sign-extension words. - Full integer operator coverage includes arithmetic, bitwise operations, shifts, comparisons, and compound assignments, with int64 fast paths and arbitrary-precision fallbacks. - The Python interface automatically exchanges BigInt values as native Python integers, preserving arbitrary precision in both directions. Several common int64 workloads are around 3–4× slower with BigInt than with raw int64_t. We recommend using BigInt when stored values may exceed the int64 range.
