--- Comment #9 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Joseph Myers <js...@gcc.gnu.org>: https://gcc.gnu.org/g:40749db75caff2fed7b7053e0d1868feaa21bcb4 commit r11-4537-g40749db75caff2fed7b7053e0d1868feaa21bcb4 Author: Joseph Myers <jos...@codesourcery.com> Date: Thu Oct 29 15:05:33 2020 +0000 stdbool.h: Update true and false expansions for C2x C2x has changed the expansions of the true and false macros in <stdbool.h> so that they have type _Bool (including in #if conditions, i.e. an unsigned type in that context). Use the new expansions in GCC's <stdbool.h> for C2x. See bug 82272 for related discussion (but this patch does *not* implement the warning discussed there). Note that it's possible there may be a further change to make bool, true and false keywords (there was support in principle for that at the April WG14 meeting). But currently these expansions of type _Bool are what C2x requires and there isn't actually a paper before WG14 at present that would introduce the new keywords. Bootstrapped with no regressions on x86_64-pc-linux-gnu. gcc/ 2020-10-29 Joseph Myers <jos...@codesourcery.com> * ginclude/stdbool.h [__STDC_VERSION__ > 201710L] (true, false): Define with type _Bool. gcc/testsuite/ 2020-10-29 Joseph Myers <jos...@codesourcery.com> * gcc.dg/c11-bool-1.c, gcc.dg/c2x-bool-1.c, gcc.dg/c99-bool-4.c: New tests.
