tree.c (type_hash_eq): For ARRAY_TYPEs also compare TYPE_SIZE.
2010-09-10 Richard Guenther <rguenther@suse.de>
* tree.c (type_hash_eq): For ARRAY_TYPEs also compare
TYPE_SIZE.
(build_index_type): Implement in terms of build_range_type.
(build_range_type): Do not allow NULL_TREE type, improve
hashing to cover more cases. Set TYPE_STRUCTURAL_EQUALITY_P
if we didn't hash.
* c-decl.c (grokdeclarator): When modifying TYPE_SIZE manually
create a distinct copy of the type.
