* gimple.c (gimple_types_compatible_p_1) <ARRAY_TYPE>: Remove bogus
size handling. (gimple_canonical_types_compatible_p) <ARRAY_TYPE>: Likewise. (iterative_hash_gimple_type): Adjust comment. (iterative_hash_canonical_type): Likewise. Hash the bounds of the domain for an array type instead of the domain type itself. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@187807 138bc75d-0d04-0410-961f-82ee72b054a4
