Yep.  The above works for me as well.  cuda_620 (sm_62 IIUC) is 
the highest currently allowed via the --mdcompute-targets 
interface.  I'll work on expanding that.

I'm not sure if the "i1" type can just plug in to 
gen_gccbuiltins.cpp as previously discussed but I'll look at that 
as well.

Thanks.
