--- Comment #2 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Martin Uecker <[email protected]>: https://gcc.gnu.org/g:68d3f1e2c20efe07f99de3720d1732c4b987ff22 commit r17-1397-g68d3f1e2c20efe07f99de3720d1732c4b987ff22 Author: Martin Uecker <[email protected]> Date: Sat Jun 6 15:08:19 2026 +0200 c: fix wrong encoding for zero-sized arrays [PR125618] This reverts one change from 106970adca69c9c577e6c75f4e69a08cd9ea2df0 that replaced build_range_type with build_index_type. In the function complete_array_type this breaks zero-sized arrays created from an empty initializer which there are represented using the C++ FE way [0, -1] causing issues on 32 bit architectures. After this partial revert this representation remains inconsistent to the usual C FE representation [0, NULL_TREE] (as before by change). PR c/125618 gcc/c-family/ChangeLog: * c-common.cc (complete_array_type): Change back to using build_range_type.
