R600g crashes while I try to use LLVM support in it. LLVM: 1:3.4~svn194296-1~exp1 Mesa: e7a5905d8a3960b0981750f8131e3af9acbfcdb8
Error message before segfault: 0x6af6c0: i32 = GlobalAddress<<4 x float> (i32)* @llvm.R600.interp.const> 0 [ORD=1]
Even running glxinfo causes this error.

--- Comment #1 from Krzysztof A. Sobiecki sobkas@gmail.com --- Tried LLVM version 1:3.4~svn194202-1~exp1 and it have the same problem, and I think it worked with an older Mesa. Will bisect Mesa in the future.
