Subject: [Bug libc/357] getcontext() on ppc32 destroys saved parameter 1 in caller's frame
Date: Mon, 30 Aug 2004 23:22:00 -0000	[thread overview]
Message-ID: <20040830232202.17433.qmail@sourceware.org> (raw)

------- Additional Comments From sjmunroe at us dot ibm dot com  2004-08-30 23:22 -------
Created an attachment (id=179)
 --> (http://sources.redhat.com/bugzilla/attachment.cgi?id=179&action=view)
Here is a patch to try

This patch fixes the problem in the testcase and preserves all registers except
R3. It was the minimum change that would work. But Paul Mackerras points out I
don't really have to perserve any of the volatile registers and burning a few
more registers would speed the code up a bit. I'll look at that tomorrow.
