Embodiment Construction

[0055] The technical solution in this application will be described below with reference to the accompanying drawings.

[0056] The embodiments of the present application are mainly applied in the technical field of computer software. Such as figure 1 As shown, it shows the flow of software source code from writing to execution. The top layer is the algorithm and application, the soul of the code, and the top-level computing principle of the entire code. High-level programming language refers to the code language written by programmers, including C language, C++, etc., and the source code programs of various software are also written in high-level programming language. A high-level programming language is converted into assembly language after being assembled by a compiler. Then the assembly language is converted into different machine codes according to different instruction set architectures. The instruction set can be understood as a bridge between software and hardware...

Abstract

The invention provides a cross-platform code conversion method and cross-platform code conversion equipment, which can be applied to the technical field of software migration (namely software transplantation) and the like. The method comprises the following steps: firstly, acquiring a first source code which can be operated on a source platform, and performing syntactic analysis on the first source code to generate a syntax tree corresponding to the first source code; identifying a to-be-converted grammar block in the grammar tree according to a grammar rule provided by the rule base; then, according to a conversion rule provided by the rule base, converting the at least one grammar block to be converted to obtain at least one converted grammar block; and finally, generating a second source code which can run on the target platform according to the obtained converted grammar block. According to the method, the grammar rule and the conversion rule provided by the rule base are used for automatically recognizing the grammar block needing to be modified in the source code and converting the grammar block, the code conversion speed and accuracy are improved, and then efficient software migration can be guaranteed.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a cross-platform code conversion method and device. Background technique [0002] In the field of computer software technology, developers use C language, C++ and other high-level programming languages ​​to write the source code of application software, so that the application software can run on the computing platform (ie: the execution environment of computer software, such as: Wintel architecture, ARM architecture, x86 architecture etc.) to run successfully. With the rapid development of computer technology, the hardware of many computing platforms with the same instruction set architecture is constantly being upgraded, so that the source code originally written may not be directly used on the new version of the computing platform (such as converting the source code from the ARMv7 instruction set architecture Computing platform migrated to ARMv8 instruction set ar...
