When the interprocedural (ipa-*) passes are running, is loop
information preserved? I'm having a hard time trying to find out if it
is in fact preserved.
I notice that loop structures can be created by flow_loops_find() in
cfgloop.c, However, this function does not appear to be aware that
there may be other functions than cfun, and as such seems not entirely
friendly to IPA.
Would a valid solution be to set cfun myself and call flow_loops_find()?
