Selecting Formats for Multi-Format Instructions in Binary Translation of Code from a Hybrid Source Instruction Set Architecture to a Unitary Target Instruction Set Architecture

摘要

A method, according to one aspect, may include estimating costs associated with translating a multi-format instruction of a source instruction set architecture to instructions of a target instruction set architecture by using a different format of the multi-format instruction for each of the costs, and selecting a format for the multiformat instruction based at least in part on the estimated costs. Methods of organizing or grouping multi-format instructions based on register use relationships. Software, hardware, and computer systems to implement the methods are also disclosed.
