headsup for llvm-3.2

[Jens-Ulrik Petersen]

Hi,

I spend a little time recently working on the llvm package trying
to fix a few Fedora bugs that have been open for a while...

I also think we should really get llvm-3.2 into Fedora 19.
I have done a few tests and scratch builds in
https://bugzilla.redhat.com/show_bug.cgi?id=903100
and am planning to build llvm-3.2 in rawhide this week hopefully.

I was hoping to get a nod first from the package owner (Michel Salim)
but I haven't heard from him yet - I dunno if he is away or just busy.
Anyway seems to me better to do the version as soon as possible
to get it into F19 Rawhide early for more testing.

I think the biggest reverse dependency is mesa which needs
to be updated to 9.1-devel, which Dave Airlie has already
after talking to him.  If you have packages that need rebuilding
for a llvm version bump let me know if you want help with
them otherwise I will try to fix any dependency breakage that occurs.

Are there any plans to bring this to F18?

There was talk about bringing 3.1 to F17 including some support from the
Mesa guys but then nothing actually happened. I would really like it if I
could go through F18 without having to build my own private parallel
installable llvm 3.2 (i need the c++11 memory model support introduced in
3.2 for my lock free algorithms).

Good question

I think it would still be good to do the 3.1 backport to F17.

3.2 requires newer Mesa and also some other version bumps
of reverse deps but perhaps it could be done later for F18
after it has been tested in Rawhide?

But I am not the package owner or comaintainer and
still kind of new to llvm so it is not really my call at this point.

I am planning now to push llvm-3.2 hopefully after the F19 Mass Rebuild
finishes (actually wish I had gotten it in before...).

3.1 doesn't directly affect me any more (since the previous discussion
some time ago f18 has been released) but i do have at least a couple
of f17 machines i would be happy to test with. At least the clang
part.

In the previous discussion [1] and more specifically [2] updating
appears to be a good thing for Mesa. Of course the Mesa people will
know better if that still applies. As with any slightly wider reaching
updates there is certainly no harm in Rawhide first and a reasonable
span in updates-testing.

If you want additional testing for f18 without blocking
updates-testing then repos.fedorapeople.org is also an option for
testing. I know a few people who would be happy to test from there.

Still doesn't prevent discussion so that all the information is
present when whoever does make the call gets around to it.

I'd appreciate llvm 3.2 and mesa 9.1 in F18, as mesa 9.1 brings support
for latest Radeon GPUs (e.g. 7950). Feel free to ping me for testing
when there are koji builds available.

Could you share your instructions for building llvm 3.2 on F18?
I tried rebuilding the F19 package, but it fails with unspecified
linker errors.

I haven't actually built it yet (was waiting as long as I could to see if
this would be done officially). Generally speaking the first step is
changing the gcc/libstdc++ version in the spec and then fix up any minor
issues afterwards, but in order to actually install and use it you need to
rebuild the other packages that depend on it (in a default Fedora setup
that's mainly Mesa) . Mesa is one package I definitely don't understand
which is why I don't like the idea of doing llvm myself.

The other alternative is what I would likely do instead and do a parallel
installable package which of course requires a bit more thought since a lot
of the libs are by default unversioned.

If it does turn out I have to do this myself though I will see about
putting a repo on fedorapeople and announce it here for those that
want/need it.

Ok, llvm-3.2 is now in F19 Rawhide. [1]

Mesa, gambas3, and OpenGTL have been rebuilt, which
should take care of libllvm dependencies,
except for "pure" which no longer seems [2] to build with libedit [3]. :-|
