Embodiment Construction

[0034] In order to better understand the technical solutions of the present invention, further description will be given below in conjunction with the accompanying drawings and through specific embodiments. The following examples are not intended to limit the present invention.

[0035] CrossBit is a dynamic binary translation system, which can provide execution environments under heterogeneous architectures by means of translation and optimization for source programs executed on various architectures. In order to achieve multi-source and multi-target, CrossBit uses an intermediate code layer, which reduces translation paths. A binary translator can be formed by only translating the front-end binary imaging program (front-end) into intermediate code blocks, and then translating the intermediate code blocks into corresponding target platform codes (back-end). If the target platform changes, only one backend needs to be changed. Currently, CrossBit supports SimpleScalar, MIPS,...

Abstract

The invention relates to a register allocation method for a super block in a dynamic binary translation system. The method is a simplified graph coloring register allocation method according to the characteristic of the super block of the binary translation system. An interference graph is constructed by activity information of variables in the super block; and then a register allocation problem is converted into an interference graph simplification problem to make an object code of the super block use an object platform register maximally and has the characteristic of high object code execution efficiency. During the allocation, the variables in a basic block are allocated with registers according to the different demands in the field of dynamic binary translation; and the allocation comprises common allocation, mandatory specified register allocation, and mandatory non-specific register allocation. The register allocation method has the characteristic of retargetability and the characteristics of good allocation effect and low allocation expense for the super block. The register allocation method is suitable for a plurality of object platforms, particularly for a multi-source multi-objective binary translation platform.

Description

technical field [0001] The invention relates to a method for allocating registers of a super block in a dynamic binary translation system, which has redirection characteristics and is applicable to various target platforms, especially multi-source and multi-target binary translation platforms. Background technique [0002] Dynamic binary translation is the most widely used method in virtual execution technology. It is an effective means to provide portability for legacy code and improve the platform adaptability of software. It can Dynamically convert the binary program on the source machine platform to run on other target machine platforms. For the dynamic binary translator itself, execution performance is a very important measure. The so-called execution performance means that, taking the efficiency of the source program running under the original architecture as a reference, the lower the efficiency loss of the source program in the operating environment provided by the ...
