Hi Mark and Jakub,

Can we backport the following patch on 3.0 branch:

http://gcc.gnu.org/ml/gcc-patches/2001-11/msg00591.html

2001-11-09  Jakub Jelinek  <jakub@redhat.com>

        * config/sparc/sparc.md (movdf): Avoid calling validize_mem during
        or after reload.


It fixes PR/4410 (verified on 3.0.2/Solaris 8).
It is a regression from 2.95.3.

Thanks,
	Stephane
