When looking into a regression for the PS3 toolchain (when I merged from 4.1.1
to 4.3.0), I noticed fwprop1 does not prop addresses at all since loop_father
will always be non NULL as the "outer loop" always exists. The outer loop
includes the whole function. I have a patch which fixes the issue and I just
need to test it. I am going to put this as a regression as cse1 used to prop
these addresses but we no longer do.
