We are retargetting gcc to our chip which can post-{in,de}crement the
base register by arbitrary number, not just by the size of the
current machine mode. As far as I can tell at this point, we have no
chance of using "native" gcc notion of post-increment but have to fix
flow.c slightly and rely on the combiner and special machine
description patterns to do the trick.

   My question has several parts:

a) does anybody out there have a similar problem?
b) any other ideas on how to solve the problem?
c) any rumors of GNU changing their mechanism for handling
   autoincrements?

Thanks in advance.
