------- Comment #22 from steven at gcc dot gnu dot org 2010-03-18 08:31 -------
In the test case from bug 43286, should_replace_address does not perform the
following replacement because the address cost is the same and the replacement
is only done if new_rtx is more expensive than old_rtx.
old_rtx
(plus:SI (reg/v/f:SI 133 [ saveArea ])
(const_int 8 [0x8]))
new_rtx
(plus:SI (reg/v/f:SI 140 [ fp ])
(const_int -8 [0xfffffffffffffff8]))
This is the same situation as described in comment #16.
