; Note: this test mimics how the naming could have been after parsing in IR in
; a LLVMContext where some types were already available; but before the
; remangleIntrinsicFunctions has happened:
; The @llvm.ssa.copy intrinsics will have to be remangled.
; In certain cases (as shown here) the remangling can result in a name clash.
; This is also related to the llvm/test/tools/llvm-linker/remangle.ll testcase that checks
; a similar situation in the bitcode reader.
