--- Comment #2 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:194ab79b580b69554124cf8257b19c957690a8a8 commit r14-8806-g194ab79b580b69554124cf8257b19c957690a8a8 Author: Jakub Jelinek <ja...@redhat.com> Date: Mon Feb 5 18:53:59 2024 +0100 c: Avoid ICE with _BitInt(N) : 0 bitfield [PR113740] finish_struct already made sure not to call build_bitint_type for signed _BitInt(2) : 1; or signed _BitInt(2) : 0; bitfields (but instead build a zero precision integral type, we remove it later), this patch makes sure we do it also for unsigned _BitInt(1) : 0; because of the build_bitint_type assertion that precision is >= (unsigned ? 1 : 2). 2024-02-05 Jakub Jelinek <ja...@redhat.com> PR c/113740 * c-decl.cc (finish_struct): Only use build_bitint_type if bit-field has width larger or equal to minimum _BitInt precision. * gcc.dg/bitint-85.c: New test.
