A big problem with maintaining SPARC is that the only full-system SPARC
regression test we have uses a proprietary Solaris boot image that can't be
distributed, meaning many people can't run the regression and can't debug
problems when they occur. (That's why it took so long to fix the previous
bug.) If you have the capability of building a simple freely distributable
full-system boot test that we could integrate with our regressions, that
would actually help a lot in terms of our ability to keep SPARC support
from rotting away.
The bits necessary for running the SPARC full-system are available here:
http://www.oracle.com/technetwork/systems/opensparc/index.html
The T1 relevant stuff is here:

Based on the notes here:
http://gedare-csphd.blogspot.dk/2010/05/week-in-m5.html
it is possible to get gem5 SPARC full-system running.
The only thing needed is replacing the Solaris 10 image with an image for
the relevant OS, e.g.
ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-7.0/sparc64/installation/miniroot/miniroot.fs.gz
(unzipped first..)
or
ftp://ftp.openbsd.org/pub/OpenBSD/5.8/sparc64/miniroot58.fs
Same should be possible for e.g. HelenOS.
Please note that the NetBSD 7.0 image is actually useless since no SPARC
sun4v support is available in the netbsd-7 release branch
