Seeking primary maintainer for LLVM

[Michel Alexandre Salim]

Dear all,

I will be reducing my involvement in packaging LLVM -- I am no longer
regularly using it, the work required to keep it up-to-date is
relatively straightforward, but there are several deficiencies that I
feel others are better positioned to address:

- - Refactorig LLVM's build system to properly use versioned shared
objects. I note that other distributions, and BSD, are still using
static linking, so we appear to be the only ones attempting to package
LLVM properly.
- - Dealing with Clang breaking when GCC is updated, and compatibility
issues with secondary architectures

Thanks to Jens for doing the 3.2 update -- and others who've been
contributing packaging patches.

Let me know if you're interested, and I'll release the package then.

Best regards,

I've never looked at llvm internals before, but it would be a fun
challenge for me.  I can take it up if you're OK with things being
broken occasionally while I figure things out.  Of course, if someone
else who has a clue wants to take it up, I'd like it if I could
co-maintain.

Given that Mesa depends on LLVM, I suppose brokenness in anything but
Rawhide is not really advisable.

I'd be happy to give you and Jens co-maintainership though, until a
more permanent maintainer steps forward (ideally one of those who have
committed semi-regularly before).

Thanks,

I expect myself, ajax or glisse need to step up to this, I'm probably
worst choice at the moment, but I can at least find the time with juhp
to the llvm/mesa lockstep updates.

Yeah, I can take this on.  I will caution that most bugs in any of the
language frontends are probably just going to be immediately moved to
upstream, and I'm mostly going to lean on the secondary arch maintainers
for arch-specific bugs.  (And that I am absolutely _not_ owning it in
EPEL or RHEL, though if someone else wants to I'm happy to advise.)  But
other than that, sure, why not.

Great! I've just released the package, please take it up at your
earliest convenience.

I am happy to help maintain package for now as a comaintainer at least.
I am not really a llvm/clang user either - my main motivation for
using/fixing it so far is that ghc uses llvm as a backend on ARM.

I think it would be best if someone who is actively using
llvm and clang directly and familiar with it and upstream
maintained the package but if noone wants to maintain it right now
I can help to maintain it for the time being at least.

Thanks for Michel for maintaining it for a long time.

And FYI, this is not just a matter of guidelines. Static LLVM also breaks 
when you have multiple libraries all using LLVM being linked together, e.g. 
OpenGTL and Mesa. Fedora switching to shared LLVM fixed those symbol 
conflicts, so going back to static is not an option.
