Paolo,
I have no problem with this patch. I would like to see it go in.
However, the ppc only has pre* auto insns and the x86 has none.
You need to test this on a machine that has post* auto insns like the
arm or the ia-64. Unfortunately we do not have these ports working
yet. If you want to track down some bugs on these ports, we would be
happy for the help.
