The dcompute parts in the compiler could definitely be improved 
(but it's nowhere on my priorities list). What I tried to get at 
by linking my comment [1] is that you can generally target 
NVPTX/AMDGCN directly, without any @compute stuff, and in that 
case importing and using intrinsics from that .di works without 
any issues.
