4735 * call.c (maybe_warn_class_memaccess): Add forward declaration.
4736 Change last argument from tree * to const vec<tree, va_gc> *, adjust
4737 args uses and check number of operands too. Don't strip away any
4738 nops. Use maybe_constant_value when looking for INTEGER_CST args.
4739 Deal with src argument not having pointer type. Check
4740 tree_fits_uhwi_p before calling tree_to_uhwi. Remove useless
4742 (build_over_call): Call maybe_warn_class_memaccess here on the
4744 (build_cxx_call): Rather than here on converted arguments.
4746 2018-01-10 Paolo Carlini <paolo.carlini@oracle.com>
4749 * init.c (build_vec_init): Avoid building an INIT_EXPR with
4750 error_mark_node as second argument.
4752 2018-01-09 Jakub Jelinek <jakub@redhat.com>
4755 * constexpr.c (cxx_eval_statement_list): Ignore DEBUG_BEGIN_STMTs
4756 in STATEMENT_LIST. Remove unneeded assert.

4762 * constexpr.c (cxx_eval_array_reference): Handle polynomial
4764 (cxx_fold_indirect_ref): Handle polynomial TYPE_VECTOR_SUBPARTS.
4765 * call.c (build_conditional_expr_1): Likewise.
4766 * decl.c (cp_finish_decomp): Likewise.
4767 * mangle.c (write_type): Likewise.
4768 * typeck.c (structural_comptypes): Likewise.
4769 (cp_build_binary_op): Likewise.
4770 * typeck2.c (process_init_constructor_array): Likewise.
4772 2018-01-03 Jakub Jelinek <jakub@redhat.com>
4775 * typeck.c (build_static_cast_1): For static casts to reference types,
4776 call build_base_path with flag_delete_null_pointer_checks as nonnull
4777 instead of always false. When -fsanitize=null, call
4778 ubsan_maybe_instrument_reference on the NULL reference INTEGER_CST.
4779 * cp-gimplify.c (cp_genericize_r): Don't walk subtrees of UBSAN_NULL
4780 call if the first argument is INTEGER_CST with REFERENCE_TYPE.
4782 2018-01-03 Nathan Sidwell <nathan@acm.org>
4785 * method.c (make_alias_for): Copy DECL_CONTEXT.
4787 2018-01-03 Marek Polacek <polacek@redhat.com>
4790 * decl.c (grokdeclarator): Don't warn about MVP in typename context.

4794 PR preprocessor/83602
4795 * name-lookup.c (lookup_name_fuzzy): Don't use macro_use_before_def
4799 * cp-gimplify.c (cp_fold) <case NOP_EXPR>: If the operand folds to
4800 error_mark_node, return error_mark_node.
4802 Update copyright years.
4804 2018-01-02 Jakub Jelinek <jakub@redhat.com>
4807 * tree.c (replace_placeholders_r): Pass NULL as last argument to
4808 cp_walk_tree instead of d->pset. If non-TREE_CONSTANT and
4809 non-PLACEHOLDER_EXPR tree has been seen already, set *walk_subtrees
4810 to false and return.
4811 (replace_placeholders): Pass NULL instead of &pset as last argument
4814 2018-01-02 Nathan Sidwell <nathan@acm.org>
4816 * constexpr.c (cxx_bind_parameters_in_call): Remove unneeded local
