nit: could we make consts somewhere that represent this 0 1 2 3 4 stuff better for easier readability?
Uh oh!

Yeah, we have one in
cuda_std
and I didn't want to duplicate it. A followup should add arustc_codegen_nvvm-types
crate thatcuda_std
andrustc_codegen_nvvm
could share (rust-gpu
has a "-types" crate for just this reason). Irust-gpu
also hasrspirv
for spirv-specific info encoded in rust types, so perhaps it should be something likercuda
? we could move the cuda error code mapping out ofcust
into it as well 🤔 )
