lto-streamer-in.c (lto_read_body_or_constructor): Set TYPE_CANONICAL only for types where LTO sets them.
* lto-streamer-in.c (lto_read_body_or_constructor): Set TYPE_CANONICAL
only for types where LTO sets them.
* tree.c (build_array_type_1): Do ont set TYPE_CANONICAL for LTO.
(make_vector_type): Likewise.
(gimple_canonical_types_compatible_p): Use canonical_type_used_p.
* tree.h (canonical_type_used_p): New inline.
* alias.c (get_alias_set): Handle structural equality for all
types that pass canonical_type_used_p.
(record_component_aliases): Look through all types with
record_component_aliases for possible pointers; sanity check that
the alias sets match.
* lto.c (iterative_hash_canonical_type): Recruse for all types
which pass !canonical_type_used_p.
(gimple_register_canonical_type_1): Sanity check we do not compute
canonical type of anything with !canonical_type_used_p.
(gimple_register_canonical_type): Skip all types that are
!canonical_type_used_p
