--- Comment #1 from amker at gcc dot gnu.org ---
Seems HPPA only supports small int in addressing mode "REG+OFFSET" of floating
mode load/store.  In effect, we can only group every two address iv uses,
resulting in 20 iv uses.  Even with this restriction, code generated with
iv_use groups is better than before.
I am going to refine the test by further relaxing nuse.

--- Comment #2 from Jeffrey A. Law  ---
HPPA 1.0 and 1.1 only support a 5 bit offset in REG+D addressing modes for
floating point loads/stores.  So, yes, it's quite limited.

For HPPA 2.0 and beyond a 14 bit offset is supported.
