Abstract

We present a unified frontend for retargetable compilers that performs analysis of the target processor model. Our approach bridges the gap between structural and behavioral processor models for retargetable compilation. This is achieved by means of instruction set extraction. The extraction technique is based on a BDD data structure which significantly improves control signal analysis in the target processor compared to previous approaches.
