While you're at it, please check if load/store multiple
insns have this problem too, and add -mno-multiple if
needed.  Also, old CBE used to have the same problem with
lwa insns; I have this old patch to GCC to add an -m option
to disable its use, I could try to dig it up if the problem
is still there on new CBEs?
