First testcase in pr44364 tickles this bug on mainline too. Looks like we need
the following.

Thank you Alan.
Trunk and 4.5 branch is affected, the 4.4 branch just built.

Actually, that's the wrong patch. The correct one stops
rs6000_split_multireg_move being called in this case, by modifying
define_mode_iterator DIFD in rs6000.md.

--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=20859&action=view)
fix pr42427 fallout
Would someone with e500 hardware please bootstrap and regression test this
patch? I'm running powerpc-linux bootstrap to ensure pr42427 doesn't regress.

I believe Edmar already bootstrapped and regtested the same patch.

I'll note that the thread I pointed to in the previous comment mentioned that I
thought we should be handling DDmode the same as DFmode (normally we do), but
Joseph's post here:
http://gcc.gnu.org/ml/gcc-patches/2008-06/msg00270.html
shows why we don't want to do that for the e500.

Reassigning since Edmar's identical patch predates mine.
