--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Thu Jan 26 19:39:40 2017 New Revision: 244949 URL: https://gcc.gnu.org/viewcvs?rev=244949&root=gcc&view=rev Log: PR c++/68727 * cp-tree.def (OFFSETOF_EXPR): Bump number of operands to 2. * cp-tree.h (finish_offsetof): Add OBJECT_PTR argument. * parser.c (cp_parser_builtin_offsetof): Pass result of build_static_cast of null_pointer_node to finish_offsetof. * semantics.c (finish_offsetof): Add OBJECT_PTR argument, use it for -Winvalid-offsetof pedwarn instead of trying to guess original offsetof type from EXPR. Save OBJECT_PTR as a new second operand to OFFSETOF_EXPR. * pt.c (tsubst_copy_and_build) <case OFFSETOF_EXPR>: Adjust finish_offsetof caller, pass the second operand of OFFSETOF_EXPR as OBJECT_PTR. * g++.dg/other/offsetof8.C: Add expected error. * g++.dg/other/offsetof9.C: New test.
