With your recent patch, GCC HEAD has some regression test failures,
which used to pass.  There are 1 new failures, and 7
failures that existed before and after that patch; 0 failures
have been fixed.

The new failures are:
native gcc.sum gcc.dg/ppc-vector-memcpy.c


This was caused by:
+2005-06-01  Josh Conner <jconner@apple.com>

+	PR 21478
+	* gimplify.c (gimplify_init_constructor): Don't spill initializer

But we are getting better results now than before on this testcase.

The testcase was testing for memcpy but we now get memset plus a store.

The array should be changed to be initialized with { 1,1,1,1,1,1,1,1 }

But I don't have time to do that at the moment.

Thanks,
Andrew Pinski
