Embodiment Construction
[0063] In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0064] Mach-O is a file format, which is the format of executable files on the macOS operating system, similar to the PE format (PortableExecutable) on Windows and the elf format (ExecutableandLinkingFormat) on Linux. C, C++, swift, and OC written by project developers can finally be compiled and linked to generate Mach-O executable files.
[0065] Assembly Language is a low-level language used in electronic computers, microprocessors, microcontrollers or other programmable devices, also known as symbolic languages. In assembly language, the opcodes of machine instructions are replaced by mnemonics, and the addresses of instructions or operands are replaced by address symbols or labels. In different devices, assembly language c...

Embodiments of the present invention provide a method, device, electronic device, and readable medium for detecting a function call. By acquiring the global symbol table and the dynamic symbol table in the application project file, the dynamic symbol table and the dynamic symbol table are extracted from the global symbol table. The target symbol corresponding to the symbol, according to the target symbol, determine the target function that matches the name of the function to be detected and the target address of the target function, and determine the target symbol from the global symbol table through the dynamic symbol table to realize function positioning, which effectively improves the accuracy of function positioning. Then, the global symbol table is disassembled to generate assembly instructions, and according to the assembly instructions and the target address of the target function, whether the target function is called is detected, and the call detection result is generated. The function address of the function is verified, and the located function is effectively called and detected, and the full detection of the calling of the target function in the application project file is realized.
Description
technical field [0001] The present invention relates to the technical field of data processing, and in particular, to a method for detecting a function call, a device for detecting a function call, an electronic device and a computer-readable medium. Background technique [0002] Xcode is an integrated development environment provided by Apple to developers, which can be used to develop macOS, iOS, WatchOS and tvOS applications. It is a user interface with unified user interface design, coding, testing and debugging. Among them, in the project development process of the application, when developers want to search for related functions in the project, they can only search through the Xcode search box. However, in this search process, the project cannot be fully searched, and the search coverage is not enough. Comprehensive, it is prone to missed detection, and each detection requires manual input of the function name, which is low in detection efficiency. Or, hook the relate...
