------- Comment #6 from pinskia at gcc dot gnu dot org 2008-01-25 22:35 -------
No this is still not fixed, we get now on the trunk as of yesterday:
foo:
li 0,8
li 9,0
mtctr 0
.p2align 3,,7
.L2:
stfsx 1,3,9
addi 9,9,4
bdnz .L2
blr
In fact I think this is worse, than what was done before but oh well. We still
don't generate the store with update instruction.
