I don't think there is such a clear line between optimized and unoptimized code for this distinction to make sense. For example, the Swift compiler frontend at -Onone generates LLVM IR that looks much more like clang at -O1 and thus exercises the dbg.value pipeline that we typically think of as optimized code even though it isn't really.
