| 16 ! we don't create a new frame yet, but work within the frame of the calling | |
| 17 ! function to give ourselves the other parameters we want | |
| 18 | |
| 19 mov %o0, %o1 ! shuffle the index up to 2nd place | |
| 20 mov %i0, %o0 ! the original 'this' | |
| 21 add %fp, 0x7ff + 136, %o2 ! previous stack top adjusted to the first argument slot (beyond 'this') | |
| 22 | |
| 23 ! save off the original incoming parameters that arrived in | |
| 24 ! registers, the ABI guarantees the space for us to do this | |
| 25 stx %i1, [%fp + 0x7ff + 136] | |
| 26 stx %i2, [%fp + 0x7ff + 144] | |
| 27 stx %i3, [%fp + 0x7ff + 152] | |
| 28 stx %i4, [%fp + 0x7ff + 160] | |
| 29 stx %i5, [%fp + 0x7ff + 168] | |
| 30 ! now we can build our own stack frame | |
| 31 save %sp,-(128 + 64),%sp ! room for the register window and | |
| 32 ! struct pointer, rounded up to 0 % 64 | |
| 33 ! our function now appears to have been called | |
| 34 ! as SharedStub(nsISupports* that, uint32_t index, uint32_t* args) | |
| 35 ! so we can just copy these through | |
