3785 2018-01-10 Paolo Carlini <paolo.carlini@oracle.com>
3787 * parser.c (cp_parser_std_attribute_spec): When
3788 token_pair::require_open / require_close return false simply
3789 return error_mark_node, avoid duplicate cp_parser_error about
3790 expected '(' / ')', respectively.
3792 2018-01-10 David Malcolm <dmalcolm@redhat.com>
3795 * call.c (null_ptr_cst_p): Strip location wrappers when
3796 converting from '0' to a pointer type in C++11 onwards.
3797 (conversion_null_warnings): Replace comparison with null_node with
3798 call to null_node_p.
3799 (build_over_call): Likewise.
3800 * cp-gimplify.c (cp_fold): Remove the early bailout when
3801 processing_template_decl.

3807 (selftest::cp_pt_c_tests): New decl.
3808 (selftest::cp_tree_c_tests): New decl.
3809 * cvt.c (build_expr_type_conversion): Replace comparison with
3810 null_node with call to null_node_p.

3816 the result for RID_TYPEID. Pass true for new "wrap_locations_p"
3817 param of cp_parser_parenthesized_expression_list. When calling
3818 warn_for_memset, replace integer_zerop calls with
3819 literal_integer_zerop, eliminating the double logical negation
3820 cast to bool. Eliminate the special-casing for CONST_DECL in
3821 favor of the fold_for_warn within warn_for_memset.
3822 (cp_parser_parenthesized_expression_list): Add "wrap_locations_p"
3823 param, defaulting to false. Convert "expr" to a cp_expr, and call

3841 (build_address): Use location of operand when building address
3844 2018-01-10 Marek Polacek <polacek@redhat.com>
3847 * call.c (build_conditional_expr_1): Check complain before warning.
3848 * pt.c (tsubst_copy_and_build) <case COND_EXPR>: Suppress
3849 -Wduplicated-branches.
3851 2018-01-10 Jakub Jelinek <jakub@redhat.com>
3854 * call.c (maybe_warn_class_memaccess): Add forward declaration.
3855 Change last argument from tree * to const vec<tree, va_gc> *, adjust
3856 args uses and check number of operands too. Don't strip away any
3857 nops. Use maybe_constant_value when looking for INTEGER_CST args.
3858 Deal with src argument not having pointer type. Check
3859 tree_fits_uhwi_p before calling tree_to_uhwi. Remove useless
3861 (build_over_call): Call maybe_warn_class_memaccess here on the
3863 (build_cxx_call): Rather than here on converted arguments.
3865 2018-01-10 Paolo Carlini <paolo.carlini@oracle.com>
3868 * init.c (build_vec_init): Avoid building an INIT_EXPR with
3869 error_mark_node as second argument.
3871 2018-01-09 Jakub Jelinek <jakub@redhat.com>
3874 * constexpr.c (cxx_eval_statement_list): Ignore DEBUG_BEGIN_STMTs
3875 in STATEMENT_LIST. Remove unneeded assert.

3881 * constexpr.c (cxx_eval_array_reference): Handle polynomial
3883 (cxx_fold_indirect_ref): Handle polynomial TYPE_VECTOR_SUBPARTS.
3884 * call.c (build_conditional_expr_1): Likewise.
3885 * decl.c (cp_finish_decomp): Likewise.

3891 2018-01-03 Jakub Jelinek <jakub@redhat.com>
3894 * typeck.c (build_static_cast_1): For static casts to reference types,
3895 call build_base_path with flag_delete_null_pointer_checks as nonnull
3896 instead of always false. When -fsanitize=null, call
3897 ubsan_maybe_instrument_reference on the NULL reference INTEGER_CST.
3898 * cp-gimplify.c (cp_genericize_r): Don't walk subtrees of UBSAN_NULL
3899 call if the first argument is INTEGER_CST with REFERENCE_TYPE.
3901 2018-01-03 Nathan Sidwell <nathan@acm.org>
3904 * method.c (make_alias_for): Copy DECL_CONTEXT.

3914 * name-lookup.c (lookup_name_fuzzy): Don't use macro_use_before_def
3918 * cp-gimplify.c (cp_fold) <case NOP_EXPR>: If the operand folds to
3919 error_mark_node, return error_mark_node.

3923 2018-01-02 Jakub Jelinek <jakub@redhat.com>
3926 * tree.c (replace_placeholders_r): Pass NULL as last argument to
3927 cp_walk_tree instead of d->pset. If non-TREE_CONSTANT and
3928 non-PLACEHOLDER_EXPR tree has been seen already, set *walk_subtrees
3929 to false and return.
