Finalizer after pass?

["Paulo J. Matos" <pocm at soton dot ac dot uk>]

Hello,

I have stumbled upon a very problematic issue. I have been, through a
pass, creating a structure of the gimple tree which fits my interests.
However, my final need is _after_ all gimple functions are processed,
to process that structure to give interesting reports to the user.
Now, I stumbled upon the fact that since passes are called
per-function, I'm generating a structure I'll not be able to access
because I don't know if the function I'm in at a given call is the
last one, nor am I able (afaik) to install a function somewhere to be
called after all functions have been processed. I'd appreciate any
input on this.
Is there a way to install a finalizing function? (to be called after
all functions in the pass have been processed)
Or to know if the current function being processed is the last one?
(maybe if I know the number of times my pass will be called!)

Cheers,
