Abstract
An optimization apparatus is provided for removing hazards from a program by rearranging instructions for each program segment. The apparatus comprises: a Directed Acyclic Graph (DAG) generating means for generating DAGs for each program segment; a hazard marking means for marking hazard-including combinations of a parent instruction and a child instruction in the DAGs for hazard; and a rearranging means for rearranging the instructions for each program segment so that instructions are inserted between the instructions of each marked combination, wherein the inserted instructions do not destroy values stored in resources used by the instructions of the marked combination.
