--- Comment #6 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:1fb467dbcc2cdd3bb89fa860a1f86b7e334e0ce3 commit r15-4863-g1fb467dbcc2cdd3bb89fa860a1f86b7e334e0ce3 Author: Jakub Jelinek <ja...@redhat.com> Date: Sat Nov 2 18:47:27 2024 +0100 gimplify: Fix up RAW_DATA_CST related ICE [PR117384] Apparently tree_output_constant_def doesn't strictly guarantee that the returned VAR_DECL will have the same or uselessly convertible type as the type of the constant passed to it, compare_constants says: /* For arrays, check that mode, size and storage order match. */ /* For record and union constructors, require exact type equality. */ The older use of tree_output_constant_def in gimplify.cc was already handling this right: ctor = tree_output_constant_def (ctor); if (!useless_type_conversion_p (type, TREE_TYPE (ctor))) ctor = build1 (VIEW_CONVERT_EXPR, type, ctor); but the spot I've added for RAW_DATA_CST missed this. So, the following patch adds that. 2024-11-02 Jakub Jelinek <ja...@redhat.com> PR middle-end/117384 * gimplify.cc (gimplify_init_ctor_eval): Add VIEW_CONVERT_EXPR around rctor if it doesn't have expected type. * c-c++-common/init-7.c: New test.
