LLVM 3.4-related build failure on Fedora/EPEL nightlies

[nalimilan]

All Fedora/EPEL nightlies have been failing since 2014-12-06 when using LLVM 3.4, but not when using 3.3 or 3.5. Below is the output for Fedora 21.

Bump!

[tkelman]

I think we're skipping 3.4, which is probably why this hasn't been responded to with any urgency.

[ViralBShah]

See #9336.

[nalimilan]

OK. But was the breakage voluntary? If not, since AFAIK LLVM versions are handled using #ifdefs, I thought it would be easy to track down and fix. If some bisection is needed I can do it.

[tkelman]

But was the breakage voluntary?

No, I'm sure it wasn't. Just a lack of people testing or worrying too much about 3.4 most likely.

If not, since AFAIK LLVM versions are handled using #ifdefs, I thought it would be easy to track down and fix.

Based on the timing it's almost definitely due to 55e2ee0

[andreasnoack]

See some of the last comments in #4853 and this #4597 (comment)

[tkelman]

Right, but that would be more of a reason to expect test failures with LLVM 3.4 that might be impossible to fix. I don't see why it would be impossible to compile with LLVM 3.4 if you really want to, especially if it was working before 2 weeks ago, but that configuration would have to be considered unsupported.

[nalimilan]

I'm fine with leaving LLVM 3.4 unsupported, I'll add a 3.3 or 3.5 package to the distributions that need it. But better state this explicitly somewhere.
