Subject: Current gcc warnings on ia64, hppa and sparc
Message-ID: <[email protected]>
Content-Type: text/plain; charset=ISO-8859-1
Hi all,
As a few servers of the GCC Compile Farm are shutdown on June, 30th because of
difficulties in their maintenance, I have just run a last build of CURRENT.
These servers were pretty interesting: Debian ia64 (HP zx6000), Debian hppa
(HP 9000/785/J6000), Debian sparc (Sun Enterprise 4500) and OpenBSD 5.1 sparc64
(Sun V210) are not easy to find for testing!
Here are the points that need investigating. I write this mail to keep a trace
of them.
Besides, a few components are shared with C TAP Harness and rra-c-util, so
maybe it could be worthwhile fixing the issues there too.
