[Gc] [PATCH] Implement the basic atomic primitives for the tilegx/tilepro cpus.

[Chris Metcalf]

* src/Makefile.am (nobase_private_HEADERS): Add tile.h.
* src/atomic_ops.h: Include tile.h file.
* src/atomic_ops/sysdeps/gcc/tile.h: New file.

For libatomic_ops:

This patch is an updated version of the CentOS 6 patch that we have
been carrying as part of our own CentOS-like distribution since 2012.

Hello,

Which gcc/clang have you tested with?
Can we remove everything except include generic.h from tile.h?

Regards,
Ivan

[Chris Metcalf]

I tested with gcc 4.4 and 4.8. My rationale for including the earlier compiler is that it is the shipped compiler with CentOS 6, which we currently support.

Please try with CFLAGS=-DAO_DISABLE_GCC_ATOMICS
Anyway, the mentioned libatomic_ops patch is supposed to be applied to v7.6+ (which is not yet released).

The version of libatomic_ops in Debian has finally been updated to 7.4.4
and cherry-picks 04a86642180 (https://tracker.debian.org/news/808756).
Of course, I went a head and tried to build it, but that fails

I'm not sure what went wrong here. Could you maybe look into it?
Maybe tile.h needs to #include "../test_and_set_t_is_ao_t.h" before
including "generic.h"?
Other than this, the tilegx bootstrap in Debian is slowly progressing
well. The toolchain appears to just work and it builds some 12 packages
already. More to come after libatomic_ops.

Sorry about that ... I got a bit confused between branches at some point
(I messed up mips too, should be fixed now).

Yeah, I guess that cherry-pick is not going to work on 7.4 branch, even though
it applies cleanly. If we can get a backport I will gladly replace
the patch in the
Debian package until the next 7.4 release

https://bugs.debian.org/841771 includes a patch that does not
necessarily work, but it lets libatomic_ops compile and makes compiling
reverse dependencies possible. Thus it helps with bootstrapping Debian
tilegx. I'd hope that libatomic_ops 7.6 is released when the rest of
essential cross compiled to tilegx. I guess I need to send patches for
guile-2.0, libbsd, openssl, gmp, and some more.

Hello Helmut,
I expect to release v7.6 by the end of this year.

Hello Chris,
Does code in libatomic_ops master branch work?

I'm not sure what went wrong here. Could you maybe look into it?
Maybe tile.h needs to #include "../test_and_set_t_is_ao_t.h" before
including "generic.h"?
Other than this, the tilegx bootstrap in Debian is slowly progressing
well. The toolchain appears to just work and it builds some 12 packages
already. More to come after libatomic_ops.

Yes, it reports all 4 tests passed on tilegx as of the current git tip.

This is the first time I've seen a warning tagged onto a Mellanox email that I have sent. Not sure what's going on there.
