607 (selftest::run_cp_tests): Move decl to bottom of file.
608 (null_node_p): New inline function.
609 (selftest::cp_pt_c_tests): New decl.
610 (selftest::cp_tree_c_tests): New decl.
611 * cvt.c (build_expr_type_conversion): Replace comparison with
612 null_node with call to null_node_p.
613 * error.c (args_to_string): Likewise.
614 * except.c (build_throw): Likewise.
615 * mangle.c (write_expression): Skip location wrapper nodes.
616 * parser.c (literal_integer_zerop): New function.
617 (cp_parser_postfix_expression): Call maybe_add_location_wrapper on
618 the result for RID_TYPEID. Pass true for new "wrap_locations_p"
619 param of cp_parser_parenthesized_expression_list. When calling
620 warn_for_memset, replace integer_zerop calls with
621 literal_integer_zerop, eliminating the double logical negation
622 cast to bool. Eliminate the special-casing for CONST_DECL in
623 favor of the fold_for_warn within warn_for_memset.
624 (cp_parser_parenthesized_expression_list): Add "wrap_locations_p"
625 param, defaulting to false. Convert "expr" to a cp_expr, and call
626 maybe_add_location_wrapper on it when wrap_locations_p is true.
627 (cp_parser_unary_expression): Call maybe_add_location_wrapper on
628 the result for RID_ALIGNOF and RID_SIZEOF.
629 (cp_parser_builtin_offsetof): Likewise.
630 * pt.c: Include "selftest.h".
631 (tsubst_copy): Handle location wrappers.
632 (tsubst_copy_and_build): Likewise.
633 (build_non_dependent_expr): Likewise.
634 (selftest::test_build_non_dependent_expr): New function.
635 (selftest::cp_pt_c_tests): New function.
636 * tree.c: Include "selftest.h".
637 (lvalue_kind): Handle VIEW_CONVERT_EXPR location wrapper nodes.
638 (selftest::test_lvalue_kind): New function.
639 (selftest::cp_tree_c_tests): New function.
640 * typeck.c (string_conv_p): Strip any location wrapper from "exp".
641 (cp_build_binary_op): Replace comparison with null_node with call
643 (build_address): Use location of operand when building address
646 2018-01-10 Marek Polacek <polacek@redhat.com>
649 * call.c (build_conditional_expr_1): Check complain before warning.
650 * pt.c (tsubst_copy_and_build) <case COND_EXPR>: Suppress
651 -Wduplicated-branches.
653 2018-01-10 Jakub Jelinek <jakub@redhat.com>
656 * call.c (maybe_warn_class_memaccess): Add forward declaration.
657 Change last argument from tree * to const vec<tree, va_gc> *, adjust
658 args uses and check number of operands too. Don't strip away any
659 nops. Use maybe_constant_value when looking for INTEGER_CST args.
660 Deal with src argument not having pointer type. Check
661 tree_fits_uhwi_p before calling tree_to_uhwi. Remove useless
663 (build_over_call): Call maybe_warn_class_memaccess here on the
665 (build_cxx_call): Rather than here on converted arguments.
667 2018-01-10 Paolo Carlini <paolo.carlini@oracle.com>
670 * init.c (build_vec_init): Avoid building an INIT_EXPR with
671 error_mark_node as second argument.
673 2018-01-09 Jakub Jelinek <jakub@redhat.com>
676 * constexpr.c (cxx_eval_statement_list): Ignore DEBUG_BEGIN_STMTs
677 in STATEMENT_LIST. Remove unneeded assert.

681 David Sherwood <david.sherwood@arm.com>
683 * constexpr.c (cxx_eval_array_reference): Handle polynomial
685 (cxx_fold_indirect_ref): Handle polynomial TYPE_VECTOR_SUBPARTS.
686 * call.c (build_conditional_expr_1): Likewise.
687 * decl.c (cp_finish_decomp): Likewise.

693 2018-01-03 Jakub Jelinek <jakub@redhat.com>
696 * typeck.c (build_static_cast_1): For static casts to reference types,
697 call build_base_path with flag_delete_null_pointer_checks as nonnull
698 instead of always false. When -fsanitize=null, call
699 ubsan_maybe_instrument_reference on the NULL reference INTEGER_CST.
700 * cp-gimplify.c (cp_genericize_r): Don't walk subtrees of UBSAN_NULL
701 call if the first argument is INTEGER_CST with REFERENCE_TYPE.
703 2018-01-03 Nathan Sidwell <nathan@acm.org>
706 * method.c (make_alias_for): Copy DECL_CONTEXT.
708 2018-01-03 Marek Polacek <polacek@redhat.com>
711 * decl.c (grokdeclarator): Don't warn about MVP in typename context.

715 PR preprocessor/83602
716 * name-lookup.c (lookup_name_fuzzy): Don't use macro_use_before_def
720 * cp-gimplify.c (cp_fold) <case NOP_EXPR>: If the operand folds to
721 error_mark_node, return error_mark_node.
723 Update copyright years.
725 2018-01-02 Jakub Jelinek <jakub@redhat.com>
728 * tree.c (replace_placeholders_r): Pass NULL as last argument to
729 cp_walk_tree instead of d->pset. If non-TREE_CONSTANT and
730 non-PLACEHOLDER_EXPR tree has been seen already, set *walk_subtrees
732 (replace_placeholders): Pass NULL instead of &pset as last argument
