Abstract :
The authors discuss graph-coloring register assignment in a retargetable compiler for long-instruction-word architectures. Of specific concern is when, during the compilation process, should register assignment be performed. The authors conclude that, for best results, register assignment should follow compaction. They discuss methods of circumventing the implementation problems inherent in such late register assignment
