Yes, it is harmless, so P4 should be better match.  The test is checking that
loop disambugiation is done one way not the other way while both are correct
choices.

Honza, any news on this?  If it is really harmless, maybe we should just make
it P4, not P2.

(In reply to comment #6)
 I am discussing with Zdenek the proper fix.

Any conclusion in sight?  If not, I'll xfail this as per protocol.

I think revision 133313

http://gcc.gnu.org/ml/gcc-cvs/2008-03/msg00531.html

is the cause.

profile fails

This seems to affect about every target, but it is essentially harmless.
I am discussing with Zdenek the proper fix.

My autotester says loop-25 fails in the same way for cris-elf, due to a patch
committed in the range 133311:133318.
