            <div>Hi,<br>
              <br>
            </div>
            Is there any way to detect which virtual registers are
            assigned to physical registers and which ones are assigned
            to memory slots?<br>
          </div>

    At the LLVM IR level, no.  However, it might be possible for a
    MachineFunctionPass to determine this or to modify the register
    allocator to record this information somewhere for query by a
    MachineFunctionPass later.<br>
    <br>
