This is probably more appropriate for the plugin's mailing list:

rather than the general gcc list...

If you're not particularly familiar with Python, then it may be easier
to write the pass directly in C.

If you're new, it's probably easiest to do it within a plugin, see:
http://gcc.gnu.org/wiki/plugins
http://gcc.gnu.org/onlinedocs/gccint/Plugins.html
LWN had an excellent tutorial on creating a new gcc pass via a plugin
here: https://lwn.net/Articles/457543/ [1]
Hope this is helpful

[1] fwiw I ported the example from the tutorial to Python here:
