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 From-SVN: r230835
