--- Comment #5 from GCC 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:114abf075c1e28358173756042049c9992ae6572 commit r15-5055-g114abf075c1e28358173756042049c9992ae6572 Author: Martin Uecker <uec...@tugraz.at> Date: Fri Nov 1 10:15:44 2024 +0100 c: minor fixes related to arrays of unspecified size The patch for PR117145 and PR117245 also fixed PR100420 and PR116284 which are bugs related to arrays of unspecified size. Those are now represented as variable size arrays with size (0, 0). There are still some loose ends, which are resolved here by 1. adding a testcase for PR116284, 2. moving code related to creation and detection of arrays of unspecified sizes in their own functions, 3. preferring a specified size over an unspecified size when forming a composite type as required by C99 (PR118391) 4. removing useless code in comptypes_internal and composite_type_internal.
