Techniques for combining veneers, indirect addressing instructions used in ARM program code.

摘要

Methods and computer program products for generating an update package based on a comparison between a base data image and a new data image, wherein the update package includes a set of instructions used for, in a remote client device, creating the new data image from the base data image, are provided. One method includes determining, by a Binary Differencing Engine (BDE), differences between the base data image and the new data image, determining, by the BDE, whether to use at least one of a branch and call instructions, generating, by the BDE, a veneer when any of the at least one of a branch and call instructions exceeds a corresponding address range, each veneer including an address, associating, by the BDE, addresses of two or more veneers with a common update package instruction, and generating, by the BDE, the update package using one or more update package instructions and associated addresses.
