Graph decompositions such as decomposition by clique separators and modular decomposition are of crucial importance for designing efficient graph algorithms. Clique separators in graphs were used by Tarjan as a divide-and-conquer approach for solving various problems such as the
Instruction scheduling and register allocation are two very In this paper, we solve register allocation and instruction scheduling simultaneously using integer linear programming (ILP). theform ulation?a new ???v ariableU has taken several approaches, including: branch-andbound e
-Register allocation may be viewed as a graph coloring problem. Each node in the graph stands for a computed quantity that resides in a machine register, and two nodes are connected by an edge if the quantities interfere with each other, that is, if they are simultaneously live a
Compilers play an important part in the system performance improvement. A compilation process is to translate source code from a highlevel programming language to a lower level language. For embedded systems, the system resource such as the number of registers, cache size, and me
Two of the most important phases of code generation for instruction level parallel processors are register allocation and instruction scheduling. Applying these two phase separately has major drawbacks like the introduction of false dependences, or a higher register pressure and
