alexandre,

when we did the dataflow stuff, my expertise was primarily in deciding which
problems could be applied to which of the passes and how and when to actually
(re)solve the equations.    i left most of the scanning of the actual rtl to
people like stevenb, richard sandiford, bonzini and dannyb.  This question is
really beyond my level of rtl expertise and i would get one of the first three
involved if i were you.

sorry

kenny
