[Q] Need sources for register allocation

Hi,


I would like to know what free code there is available for
implementing register allocation for a backend we are implementing.


Our target is a virtual machine with a RISC-like load/store
architecture. At the moment we generate code using an unlimited number
of registers and now we want to map the virtual registers to a
reasonable number of real registers (32, 64).


We have thought of the classical graph-coloring approach.


Any pointers to such code will be appreciated.
