     in the frame for the function that called SharedStub are the

 */

 SharedStub:

 ! we don't create a new frame yet, but work within the frame of the calling

 ! function to give ourselves the other parameters we want

         mov     %o0, %o1            ! shuffle the index up to 2nd place

         mov     %i0, %o0            ! the original 'this'

         add     %fp, 72, %o2        ! previous stack top adjusted to the first argument slot (beyond 'this')

 ! save off the original incoming parameters that arrived in 

 ! registers, the ABI guarantees the space for us to do this

         st      %i1, [%fp + 72]

         st      %i2, [%fp + 76]

         st      %i3, [%fp + 80]

         st      %i4, [%fp + 84]

         st      %i5, [%fp + 88]

 ! now we can build our own stack frame

         save    %sp,-(64 + 32),%sp  ! room for the register window and

                                     ! struct pointer, rounded up to 0 % 32

 ! our function now appears to have been called

 ! as SharedStub(nsISupports* that, uint32_t index, uint32_t* args)

 ! so we can just copy these through

         mov     %i0, %o0

         mov     %i1, %o1

         mov     %i2, %o2

         call    PrepareAndDispatch

         nop

         mov     %o0,%i0             ! propagate return value

         b .LL1

         nop

 .LL1:

         ret

         restore

        .size    SharedStub, .-SharedStub

        .type    SharedStub, #function
