--- Comment #3 from CVS 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:7840b4dc05539cf5575b3e9ff57ff5f6c3da2cae commit r11-2648-g7840b4dc05539cf5575b3e9ff57ff5f6c3da2cae Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Aug 11 16:46:49 2020 +0200 c-family: Fix ICE in get_atomic_generic_size [PR96545] As the testcase shows, we would ICE if the type of the first argument of various atomic builtins was pointer to (non-void) incomplete type, we would assume that TYPE_SIZE_UNIT must be non-NULL. This patch diagnoses it instead. And also changes the TREE_CODE != INTEGER_CST check to !tree_fits_uhwi_p, as we use tree_to_uhwi after this and at least in theory the int could be too large and not fit. 2020-08-11 Jakub Jelinek <ja...@redhat.com> PR c/96545 * c-common.c (get_atomic_generic_size): Require that first argument's type points to a complete type and use tree_fits_uhwi_p instead of just INTEGER_CST TREE_CODE check for the TYPE_SIZE_UNIT. * c-c++-common/pr96545.c: New test.
