--- Comment #5 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:e0c3066c14ad98d130ddd1183be3caaeea19c63b commit r16-894-ge0c3066c14ad98d130ddd1183be3caaeea19c63b Author: Jonathan Wakely <jwak...@redhat.com> Date: Fri May 16 13:05:51 2025 +0100 libstdc++: Support std::abs for 128-bit integers and floats [PR96710] Currently we only provide std::abs(__int128) and std::abs(__float128) for non-strict modes, i.e. -std=gnu++NN but not -std=c++NN. This defines those overloads for strict modes too, as a small step towards resolving PR 96710 (which will eventually mean that __int128 satisfies the std::integral concept). libstdc++-v3/ChangeLog: PR libstdc++/96710 * include/bits/std_abs.h [__SIZEOF_INT128__] (abs(__int128)): Define. [_GLIBCXX_USE_FLOAT128] (abs(__float128)): Enable definition for strict modes. * testsuite/26_numerics/headers/cmath/82644.cc: Use strict_std instead of defining __STRICT_ANSI__. * testsuite/26_numerics/headers/cstdlib/abs128.cc: New test.
