The situation has improved, as the biv has now been spotted, and the loop
turned into,
.foo:
li 0,8
mtctr 0
.align 4
.L2:
stfs 1,0(3)
addi 3,3,4
bdnz .L2
blr
Unfortunately this has placed the increment after the load, and so
cannot be merged into it. If the loop optimizer knew the target had
pre-inc, it might be able to swap them round by biasing the pointer
before the loop.
