...t convinced me that I really could go with a stack machine for the work I'm doing. I'm planning on implementing register allocation based partially on your paper. Actually, I was wondering if any of your lcc implementation work was publicly available. -- Wesley J.

...format that I can easily read from Python, where the I'm implemented the bulk of my actual backend. I'm doing this largely to avoid writing an .ll or .bc parser (which wouldn't be terrible, but I'm not sure how stable those formats really are). -- Wesley J.

...;m just trying to make sure I'm taking the right approach before I run head first into any dead ends. Ultimately, I'd rather do things "right" than "fast", since in my experience, "right" takes less time in the long run. ;) -- Wesley J.

Wesley, Regarding access to the source code; I would send you the code, but I might be stepping on a few toes. The person to speak to is Chris Bailey at the University of York (in the UK). However it is written for the lcc tree-based IR, rather than the SSA-based IR of LLVM, so I don't think it will be that much use. A lot of the analysis it does is to find information that is explicit in
