--- Comment #22 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:31c3b67dfc6e67773d13260bc38b833663698b74 commit r14-2753-g31c3b67dfc6e67773d13260bc38b833663698b74 Author: Jonathan Wakely <jwak...@redhat.com> Date: Mon Jul 24 11:45:43 2023 +0100 libstdc++; Do not use strtold for hppa-hpux [PR110653] When I switched std::stold to depend on HAVE_STRTOLD that enabled it for hppa-hpux which defines HAVE_BROKEN_STRTOLD. Add a check for that macro so that we don't use strtold, and fall through to the check for double and long double having the same representation. That should mean we define a conforming std::stold in terms of std::stod, instead of trying to use the broken strtold. Also fix a logic error in the fallback definition of std::stod, which should not treat zero as a subnormal number. libstdc++-v3/ChangeLog: PR libstdc++/110653 * include/bits/basic_string.h [!HAVE_STOF] (stof): Do not throw an exception for zero result. [HAVE_BROKEN_STRTOLD] (stold): Do not use strtold.
