1201 * call.c (maybe_warn_class_memaccess): Add forward declaration.
1202 Change last argument from tree * to const vec<tree, va_gc> *, adjust
1203 args uses and check number of operands too. Don't strip away any
1204 nops. Use maybe_constant_value when looking for INTEGER_CST args.
1205 Deal with src argument not having pointer type. Check
1206 tree_fits_uhwi_p before calling tree_to_uhwi. Remove useless
1208 (build_over_call): Call maybe_warn_class_memaccess here on the
1210 (build_cxx_call): Rather than here on converted arguments.
1212 2018-01-10 Paolo Carlini <paolo.carlini@oracle.com>
1215 * init.c (build_vec_init): Avoid building an INIT_EXPR with
1216 error_mark_node as second argument.
1218 2018-01-09 Jakub Jelinek <jakub@redhat.com>
1221 * constexpr.c (cxx_eval_statement_list): Ignore DEBUG_BEGIN_STMTs
1222 in STATEMENT_LIST. Remove unneeded assert.

1230 (cxx_fold_indirect_ref): Handle polynomial TYPE_VECTOR_SUBPARTS.
1231 * call.c (build_conditional_expr_1): Likewise.
1232 * decl.c (cp_finish_decomp): Likewise.

1238 2018-01-03 Jakub Jelinek <jakub@redhat.com>
1241 * typeck.c (build_static_cast_1): For static casts to reference types,
1242 call build_base_path with flag_delete_null_pointer_checks as nonnull
1243 instead of always false. When -fsanitize=null, call
1244 ubsan_maybe_instrument_reference on the NULL reference INTEGER_CST.
1245 * cp-gimplify.c (cp_genericize_r): Don't walk subtrees of UBSAN_NULL
1246 call if the first argument is INTEGER_CST with REFERENCE_TYPE.
1248 2018-01-03 Nathan Sidwell <nathan@acm.org>
1251 * method.c (make_alias_for): Copy DECL_CONTEXT.

1256 * decl.c (grokdeclarator): Don't warn about MVP in typename context.

1261 * name-lookup.c (lookup_name_fuzzy): Don't use macro_use_before_def
1265 * cp-gimplify.c (cp_fold) <case NOP_EXPR>: If the operand folds to
1266 error_mark_node, return error_mark_node.
1268 Update copyright years.
1270 2018-01-02 Jakub Jelinek <jakub@redhat.com>
1273 * tree.c (replace_placeholders_r): Pass NULL as last argument to
1274 cp_walk_tree instead of d->pset. If non-TREE_CONSTANT and
1275 non-PLACEHOLDER_EXPR tree has been seen already, set *walk_subtrees
1276 to false and return.
1277 (replace_placeholders): Pass NULL instead of &pset as last argument
