--- Comment #3 from CVS 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:f69a8299c1d95548e1539227fb7b8f5581aeb29b commit r13-4117-gf69a8299c1d95548e1539227fb7b8f5581aeb29b Author: Jonathan Wakely <jwak...@redhat.com> Date: Wed Nov 16 20:47:39 2022 +0000 libstdc++: Ensure std::to_chars overloads all declared in <format> [PR107720] For powerpc64le we need to be able to format both of __ieee128 and __ibm128, so we need the std::to_chars overloads for both types to be visible at once. The __ieee128 overloads are always visible in C++23 mode, because they're used to implement the _Float128 overloads. The __ibm128 overloads are only visible when long double is __ibm128. libstdc++-v3/ChangeLog: PR libstdc++/107720 * include/std/format [_GLIBCXX_LONG_DOUBLE_ALT128_COMPAT]: Declare overloads of std::to_chars for the alternative long double type.
