Not sure if meaningful in any way, but noticed that the following command also fails:
ccall(“llvm.nvvm.cp.async.commit.group”, llvmcall, Cvoid, ())
ERROR: LLVM error: Cannot select: intrinsic %llvm.nvvm.cp.async.commit.group
Stacktrace:
[1] handle_error(reason::Cstring)
@ LLVM ~/.julia/packages/LLVM/2JPxT/src/core/context.jl:194
Also, llvm.nvvm.membar.sys is now formally depreciated (again not sure if useful info).
