--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-10-12 18:23:13 UTC --- Author: jakub Date: Fri Oct 12 18:23:03 2012 New Revision: 192406 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=192406 Log: PR c/54381 * c-common.h (sizeof_pointer_memaccess_warning): Adjust prototype. * c-common.c (sizeof_pointer_memaccess_warning): Take array of 3 locs and array of 3 trees instead of just single loc and single sizeof_arg tree. Handle __builtin___*_chk builtins too, and also stpncpy, bcopy, bcmp, bzero, snprintf and vsnprintf builtins. For *cmp* builtins that take two sources strings report warnings about first and second source, not about destination and source. * c-parser.c (struct c_tree_loc_pair): Removed. (c_parser_expr_list): Remove struct c_tree_loc_pair * argument, add location_t * and tree * arguments, fill in array of 3 sizeof_arg trees and corresponding locs. (c_parser_attributes, c_parser_objc_keywordexpr): Adjust c_parser_expr_list callers. (c_parser_postfix_expression_after_primary): Likewise. Pass array of 3 sizeof_arg trees and locs (corresponding to first 3 arguments) to sizeof_pointer_memaccess_warning. * semantics.c (finish_call_expr): Pass array of 3 sizeof_arg trees and locs (corresponding to first 3 arguments) to sizeof_pointer_memaccess_warning. * c-c++-common/Wsizeof-pointer-memaccess1.c: New test. * c-c++-common/Wsizeof-pointer-memaccess2.c: New test. * gcc.dg/Wsizeof-pointer-memaccess1.c: New test. * gcc.dg/torture/Wsizeof-pointer-memaccess1.c: Test also stpncpy. Adjust expected wording of warnings for *cmp* builtins. * g++.dg/torture/Wsizeof-pointer-memaccess1.C: Likewise. * g++.dg/torture/Wsizeof-pointer-memaccess2.C: Likewise.
