--- Comment #8 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Martin Uecker <uec...@gcc.gnu.org>: https://gcc.gnu.org/g:54be338589ea93ad4ff53d22adde476a0582537b commit r14-3004-g54be338589ea93ad4ff53d22adde476a0582537b Author: Martin Uecker <uec...@tugraz.at> Date: Fri Aug 4 07:48:21 2023 +0200 c: _Generic should not warn in non-active branches [PR68193,PR97100,PR110703] To avoid false diagnostics, use c_inhibit_evaluation_warnings when a generic association is known to not match during parsing. We may still generate false positives if the default branch comes earler than a specific association that matches. PR c/68193 PR c/97100 PR c/110703 gcc/c/: * c-parser.cc (c_parser_generic_selection): Inhibit evaluation warnings branches that are known not be taken during parsing. gcc/testsuite/ChangeLog: * gcc.dg/pr68193.c: New test.
