Fix strict aliasing warning in rb_int128_to_numeric

2025-12-08T23:01:05+00:00

If we don't have uint128, then rb_int128_to_numeric emits a strict
aliasing warning:

    numeric.c:3641:39: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
    3641 |         return rb_uint128_to_numeric(*(rb_uint128_t*)&n);
         |                                       ^~~~~~~~~~~~~~~~~

Add support for `u128`, `U128`, `s128` and `S128` integers to `IO::Buffer`. (#15399)

Improve performance of bignum[beg, len] (#14007)

Implement rb_big_aref2.
Taking a small slice from large bignum was slow in rb_int_aref2.

Faster Integer.sqrt for large bignum

Integer.sqrt uses Newton's method.
This pull request reduces the precision which was unnecessarily high in each calculation step.

Use `UNDEF_P`
