Problems solved by technology
[0003] Static linking usually needs to link the same areas in each compiled module together to become an executable file. Since the object file in the static library before static linking is not an executable unit, the object file will not be calculated before the static linking is completed. Therefore, it is difficult to determine the address parameters of the target code before static linking, which cannot meet the needs of reverse analysis of target files before static linking

The invention provides a code relocation method and device, and the method comprises the steps: firstly obtaining a to-be-relocated target file, and reading a loading command list corresponding to a target code from the target file; wherein the target file is used for generating an executable file through a static link; then, on the basis of the loading command list, searching a relocation information list corresponding to the target code from the target file; then, based on the relocation information list, determining a target address calculation mode and address parameters of the target code; and finally, calculating the address parameter by using the target address calculation mode to obtain address information after the target code is repositioned. According to the method, the target address calculation mode and the address parameter of the target code are determined through the relocation information list, the address parameter is calculated by utilizing the target address calculation mode, the relocated address information is obtained, and the address information of the target code can be determined without a static link.
Description
technical field [0001] The present disclosure relates to the field of computer technology, and in particular, to a code relocation method and device. Background technique [0002] In the process of application development, the code is usually placed in multiple source files, and these source files are not independent, there will be a variety of dependencies, such as one source file may need to call another source file defined functions, but each source file is compiled independently. To this end, the object files generated by compiling these source files need to be linked to form an executable program. The linking process is static linking. [0003] Static linking usually needs to link the same areas in each compiled module together to become an executable file. Since the object file in the static library before static linking is not an executable unit, the object file will not be calculated before the static linking is completed. Therefore, it is difficult to determine the...
