alias.c (struct alias_set_entry): New field has_zero_child.
* alias.c (struct alias_set_entry): New field has_zero_child.
(mem_in_disjoint_alias_sets_p): Return 0 if set in either ase.
(get_alias_set): If language-dependent routine set TYPE_ALIAS_SET,
do nothing.
Call record_component_aliases for aggregate types.
(record_alias_subset): Set has_zero_child.
(record_component_aliases, case ARRAY_TYPE): Do nothing if
TYPE_NONALIASES_COMPONENT.
(record_component_aliases, case RECORD_TYPE): Test
DECL_NONADDRESSABLE_P.
* c-decl.c (grokdeclarator): Set DECL_NONADDRESSABLE_P instead
of TREE_ADDRESSABLE.
* calls.c (initialize_argument_information): Only test
TYPE_TRANSPARENT_UNION for UNION_TYPE.
* function.c (assign_parms): Likewise.
* integrate.c (function_cannot_inline_p): Likewise.
* stor-layout.c (finish_record_layout): Don't call
record_component_aliases.
* tree.h (struct tree_int_cst): Use struct tree_common.
(struct tree_real_cst, struct tree_string): Likewise.
(struct tree_complex, struct tree_identifier): Likewise.
(struct tree_list, struct tree_vec, struct tree_exp): Likewise.
(struct tree_block, struct tree_type, struct tree_decl): Likewise.
(TYPE_TRANSPARENT_UNION): Use UNION_TYPE_CHECK.
(TYPE_NONALIASES_COMPONENT): New macro.
(TYPE_AMBIENT_BOUNDEDNESS): Use FUNCTION_TYPE_CHECK.
(DECL_NONADDRESSABLE_P): New macro.
(struct tree_decl): Reorder bits for clarity of how many left;
add non_adressable.
* cp/cp-tree.h: Use struct tree_common instead of a char array.
* cp/decl.c (grokdeclarator): Set DECL_NONADDRESSABLE_P instead
of TREE_ADDRESSABLE.
