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
