What steps will reproduce the problem?
1. Run CUDA program linked with gpuocelot as in documentation.

What is the expected output? What do you see instead?
- Should run normally with "llvm" backend.
Runs normally (but slow) only with "emulated" backend.

What version of the product are you using? On what operating system?
-Latest from svn, latest llvm-3.4svn, Gentoo GNU/Linux linux-3.8.8, glibc-2.15, 
gcc-4.6.3

Please provide any additional information below.
-Could not find any clues on google.

I don't have time to learn all the details so I found the type that was 
'invalid' - ir::PTXInstruction::Const and added it to the choice list.
Brute force worked.
Why Const was not included?
Thanks.
