    9595Note that the graph still contains: 
    9696 * '''Variables''' (ie local register that are not yet mapped to particular machine registers) 
    97  * '''Stack-slot addressing modes''', which include late-bound compile-time constants, such as the offset in the frame of the a variable spill location, or BlockId stack-top-on-entry. 
     97 * '''Stack-slot addressing modes''', which include late-bound compile-time constants, such as the offset in the frame of the a variable spill location, or !BlockId stack-top-on-entry. 
    9898 
    9999The invariant is that each node could be done by one machine instruction, provided each `LocalReg` maps to a (suitable) physical register; and an instruction involving a stack-slot can cope with (Sp+n).
