--- Comment #3 from Vladimir Makarov <vmakarov at gcc dot gnu.org> ---
Actually, it is not a failure.  I believe it is an improvement.  We have less
move insns now.  The easiest way to fix is to change the expected move insns to
the current number.

I'd prefer changing the exact counts to less or equal number of the counts. 
But I don't know how to write it using dejagnu test directives.
