[Bug target/25662] [4.0/4.1 Regression] Unrecognizable insn with -O on PPC

[pinskia at gcc dot gnu dot org]

------- Comment #1 from pinskia at gcc dot gnu dot org  2006-01-04 14:37 -------
This works on the mainline as of today but failed with 4.2.0 20051219.

Confirmed.  Though I should note this is really weird as DOM is messing up in
that version of GCC and we still have 1 << -1 which is not being folded.
