Survey: Can we drop support for LLVM versions prior to 3.5?

[Kai Nacke via digitalmars-d-ldc]

Hi all!

Currently LDC can be compiled with LLVM 3.1-3.6 with support for 
LLVM trunk constantly added.

Because the LLVM API is not stable this broad support becomes 
more and more a burden. It is also likely that this set of LLVM 
libraries will not be supported by the new Travis container 
(which I like to use because of more RAM and CPU cores).

Versions 3.1, 3.2 and 3.3 have serious bugs which forces us to 
disable optimizations for some tests. Especially 3.3 is unusable 
with OS X!

Therefore I like to know which LLVM version do you use with LDC.

If no one objects then the plan would be that the next major 
release is the last one which can be compiled with LLVM 3.1-3.4.

Please give feedback!

Regards,
Kai
