I didn't modify the code. for some reasons, the linaro ubuntnu 12.04 full file
system uses hard fp compiler, even though I used 4.6 hard fp to do the cross
compile for LLVM, there are some mismatch. So, I have to fallback to 11.04
linaro filesystem, it is softfp, then I used 4.6 softfp compiler to do cross
compile LLVM, then it seems fine. I can run the test cases inside the package
on the target.
I mean float vector has issue. I will add the test case next week.
Regards,
Yi

Good. Do you have any patches you could contribute to pocl for others to get
it more easily running on ARM?

As far as I've understood ARM should be one of the more stable
backends in LLVM. Perhaps this is the floating-point ABI mismatch
issue. What is the test case? All floating point kernels? Float
vectors perhaps?
