I am working on developing register allocator for irregular
architectures (with register
pair, and banks) and plan to base my work on graph coloring register
I wonder if LLVM already has basic graph coloring register
allocator, or somebody is
working on it?
Also, I'm not sure what is the best way to even describe the
register constraints in
- How can I describe register pairs?
- It it possible to have overlapping register classes?
