Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Seems BIT_FIELD_REF is already handled in chkp_process_stmt (and e.g. TARGET_MEM_REF too), but not in the other routine. Just noticed: case ARRAY_RANGE_REF: printf("ARRAY_RANGE_REF\n"); debug_gimple_stmt(gsi_stmt(*iter)); debug_tree(node); gcc_unreachable (); break; that really shouldn't have made through (wrong formatting, printing on stdout), guess gcc_unreachable (); alone without break; afterwards would be more than enough.
