Some extra expected assembler output addi instructions. The difference in the
assembler is this:
12,15d11
< rldicl 5,5,0,60
< li 9,32
< addi 10,5,-48
< add 5,10,1
16a13
> li 9,32
17a15,16
> rldicl 5,5,0,60
> add 5,10,5
32,35d30
< rldicl 5,5,0,60
< li 9,32
< addi 10,5,-48
< add 5,10,1
36a32
> li 9,32
37a34,35
> rldicl 5,5,0,60
> add 5,10,5
53,56d50
< rldicl 5,5,0,60
< li 9,32
< addi 10,5,-48
< add 5,10,1
57a52
> li 9,32
58a54,55
> rldicl 5,5,0,60
> add 5,10,5
So it looks like 3 extra addi's are generated.
