I'm too lazy to power up some, sorry.  But how about looking at
the code, instead?


code filll
         mr      r4,r20
         lwz     r3,0(r31)
         lwz     r5,4(r31)
         mr.     r3,r3
         lwzu    r20,8(r31)
         addi    r31,r31,4
         ble-    0x2c
         addic.  r3,r3,-4
         stw     r4,0(r5)
         addi    r5,r5,4
         bc+     20,lt,0x18
         blr
end-code

(That weirdo "bc" at the end is just an unconditional jump, coded
very strangely).
