I wonder how hard it would be to just use Generic directly to code programs. Probably would just be an exercise in insanity.
OLS: GCC: present and future

We have discussed the notion of reading the various ILs and be able to start compilation from an arbitrary stage in the pipeline. This would allow us to get us closer to implement some degree of unit testing.
For instance, someone finds a bug in dead code elimination that only happens when the IL shows a specific stream of instructions with a specific combination of memory references.
Instead of trying to recreate that IL pattern out of source code, we would be able to create it and feed it to DCE directly. That would eliminate random changes in the first N - 1 passes that may paper over the original bug.
