GCC Plug-in Framework ready to port

Dear mailing list:

My research group (the High-Confidence Operating Systems group at  
Stony Brook University;
home page http://www.fsl.cs.sunysb.edu/hcos/) continues to use a  
modified branch of
Subversion GCC that hosts plug-ins written in C, C++, and (with a  
little work) Python.

We published a GCC Summit paper on this, called "Extending GCC with  
Modular GIMPLE
Optimizations" (Callanan, Dean, and Zadok).  We have developed a  
variety of plug-ins,
including:

- A GIMPLE virtual machine, developed by another team at the university,
- A generic run-time AOP architecture, currently in preparation,
- Bounds-checkers and execution tracers,

and more.

We are willing to contribute the effort necessary to integrate this  
system into the current
main-line GCC, and feel that it is simple and general enough that many  
other systems could
be built on top of it.

We've been off the ML for some time, but we're still out there.  Is  
this something that is
wanted, or have we been overtaken by events and should be porting to  
someone else's
implementation?

Sincerely,
Sean Callanan
