Identifying global state within GCC


I had a go at writing a custom pass to try to locate places where GCC
makes use of global state.

You can see the pass here (which I implemented using gcc-python-plugin):
https://gcc-python-plugin.readthedocs.org/en/latest/working-with-c.html#finding-global-variables

A build log from recompiling gcc using this pass can be seen at:
http://fedorapeople.org/~dmalcolm/gcc/2013-05-01/make.log
(about 12MB in size; I killed it when I saw that stage 1 was done).

I'm sure there are quite a few false positives in there.

Hope this is helpful.  FWIW I had an earlier version of the pass which
merely gave *declaration* sites for global variables, rather than all
*uses* of such variables.
