I'm not sure how GEM (another Stony Book University project) relates to
the talk given at this year's GCC Summit, but there was a talk about a
plug-in architecture for GCC to allow modules to operate on the GIMPLE
IR ("Extending GCC with Modular GIMPLE Optimisations" by Sean Callanan).
This work was well received and is currently being prepared on a branch;
I expect it will be introduced to the mainline at some point. You might
like to check out the proceedings of the summit for more details on it:
