architecture status, please

[Ulrich Drepper]

I think things have stablelized now and we can think about 2.3.2.  Do
all architectures which worked in 2.3.1 work now?  Are any other
architectures which didn't work in 2.3.1 close to working with the
current tree?

I have one small patch queued for tomorrow and need to check the Dist files. 
Besides that PPC32 is fine.

I've heard from SH kernel people that the kernel fixes the syscall
ABI for pread/pwrite* since the old one didn't work properly on SH-4
anyway, and a small fix is required in libc.
I'll send a patch for it till tomorrow. There are no other known
problems on SH.

[PATCH] SH: fix pread/pwrite (Was: architecture status, please)

[kaz Kojima]

Hi,

This is a patch for syscall ABI fixing of pread/pread64/pwrite/pwrite64
on SH linux target. Kernel folks took the MIPS's way.

Regards,
	kaz

Thanks, I've added the patch.

x86-64 works and passes the complete testsuite with the exception of
the linuxthreads/ex18 problem that I mentioned on libc-alpha.

But this didn't work in 2.3.1 either, so we're as good as before - and
in most areas we're better ;-).

So, feel free to go ahead.

A prerelease might be a good idea,

[Andreas Jaeger]

With a fixed kernel for x86-64, I just tested current CVS successfully
with:
- with-tls --without-thread
- normal (--without-tls --without-thread)

The whole testsuite passed.

So, the x86-64 architecture support looks fine with current CVS glibc
and current CVS kernel

and
--with-tls --with-__thread
is what I've tested yesterday (in addition to the usual
--with-tls --without-__thread).

Ditto.

Alpha works --with-tls --without-__thread.

With the sysdep.h patch I sent earlier, Arm seems to be working at least
as well as it did in 2.3.1.  "make check" passes with no errors other
than the normal ones relating to floating point.

unwind info fix for ia64

[David Mosberger]

Here is a small bug-fix for libc's __syscall_error to get the unwind
info correct.  Did "make check" afterwards and ran a test program to
verify that unwinding works correctly now for this function.

I've applied the patch.  Thanks,
