Hi Yang, nice to meet you.
I agree with LLVM changing code from the development branch, but in this
case, the compilation is failing because they switched to a stricter
language convention, so it might be wiser to fix the code sooner then later.
Im also creating beignet packages for future inclusion in ubuntu (im just a
community contributor, not a canonical employee), and ive been testing
beignet + opencl (mesa) for radeon and intel drivers. So it would help me
alot if you guys could fix this compilation, since i have a few bugs i want
to commit to you guys but i need to test latest mesa, intel, radeon code.
Best regards
