    ARC Subroutine that Performs a Swap Operation

    Please help an ARC subroutine that performs a swap operation on the 32-bit operands
    x=25
    y=50
    which are stored in memory. Please use as few registers as possible. Thanks!!

    UPDATE: The ARC is a 32-bit machine with byte addressable memory. It can manipulate 32 bit data types, but all data is stored in memory as bytes, and the address of a 32 bit word is the address of its byte that has the lowest address.
