; Test that non-overloaded AMDGCN intrinsics returning pointers with specific
; address spaces are correctly round-tripped through SPIR-V.
;
; SPIR-V represents all pointer types using storage classes, and the Generic
; storage class maps to addrspace(0) in LLVM. Intrinsics like
; llvm.amdgcn.implicitarg.ptr canonically return ptr addrspace(4) (Constant),
; but when round-tripped through SPIR-V, the reader reconstructs them with
; addrspace(0) unless it uses LLVM's canonical intrinsic declaration.
