LLVM 3.5 or LLVM get me error
"LLVM ERROR: Do not know how to split the result of this operator!"
 for lot operations done by Mesa llvmpipe.

LLVM is compiled with -march=native.

On my A8-3870 I getting these errors, on AMD Athlon 64 X2 TK-55 same examples
work very well.

Attaching /proc/cpuinfo

I can do tests if needed except compiling LLVM with debug.
