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.
