That's something I've been meaning to ask, the difference I know of right now 
is that `amdgcn--` will not create a ROCm toolchain so we don't do any of that. 
However, I don't know to what extent the `hsa` in the triple matters, because 
there's certain builtins that are tied to the implicit arguments. I never knew 
if that was an `hsa` thing or we considered the code object universal to 
`amdgcn--`. I mostly just meant that IR compiled with `amdgcn--` should be able 
to link with the HSA os version.
