Subject: [PATCH]: Core regset support for Linux/SPARC.
Date: Thu, 06 Apr 2006 21:52:00 -0000 [thread overview]
Message-ID: <20060406.145119.102460789.davem@davemloft.net> (raw)
Thankfully the Sparc target layer already had nice generic
support for this, so it was merely a matter of defining some
offsets and some small helper stubs.
Ok to apply?
