--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This is a clear bug in s390_const_int_pool_entry_p.  It just uses
get_pool_constant but ignores get_pool_mode, which on big-endian is
significant.  The function doesn't allow offsets like e.g. simplify-rtx.cc
(avoid_constant_pool_reference), but still needs to deal with mode mismatch=
es.=
