code: @Override
      public void visitMethod(Method obj) {
          suspectLocals.clear();
          int[] parmRegs = RegisterUtils.getParameterRegisters(obj);
          for (int pr : parmRegs) {
              suspectLocals.put(Integer.valueOf(pr), new RegisterInfo(RegisterUtils.getLocalVariableEndRange(obj.getLocalVariableTable(), pr, 0)));
          }
      }
