--- Comment #3 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:92b38ec84f2990d217f036dc6c5a32cde5ecfb93 commit r14-9879-g92b38ec84f2990d217f036dc6c5a32cde5ecfb93 Author: Jonathan Wakely <jwak...@redhat.com> Date: Mon Apr 8 17:37:32 2024 +0100 libstdc++: Fix build for targets without FP std::from_chars [PR114633] If the faster std::from_chars is not supported for floating-point types then just extract the value from the stream using operator>>. This fixes a build error for targets where __cpp_lib_to_chars is not defined. libstdc++-v3/ChangeLog: PR libstdc++/114633 * include/bits/chrono_io.h (_Parser::operator()) <'S'>: Use stream extraction if std::from_chars is not available.
