Good because SPECFP2000 for ppc64 is 0.5% better (SPECInt2000 is the
same) on the branch than on the mainline at the last merge point.  And
this patch could remove this achievement.

There's now daily SPEC2k and C++bench (tramp3d, DLV and others) numbers from dataflow branch available from http://www.suse.de/~gcctest/SPEC/C{INT|FP}/sb-haydn-df-64/ and http://www.suse.de/~gcctest/c++bench-haydn-df/ (or follow the links from gcctest's home page)
