Some intrinsics of the LLVM NVPTX backend have argument types
i8 addrspace(x)*
.At the moment, there is no way to
ccall
these intrinsics, sinceRef{T}
is converted to the plaini8*
.As discussed in JuliaGPU/CUDAnative.jl#548, this PR adds an
ASPtr{T, AS}
type whose sole purpose is to ensure that codegen emits an LLVMi8 addrspace(x)*
when usingccall(..., llvmcall, ...)
