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

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

|
add %fp, 0x7ff + 136, %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 + 0x7ff + 136]

save %sp,-(128 + 64),%sp ! room for the register window and

! as SharedStub(nsISupports* that, PRUint32 index, PRUint32* args)
