Hello,


I have a question about register allocation using a graph coloring
algorithm.
The front-end of my compiler produces a three address code
representation.
The register allocation should be performed on the intermediate
representation (to assign temporaries to registers) or should I choose
the instructions of the target processor first, assuming an infinite
number of registers and then use the register allocation to match the
actual set of registers ?
