File processing method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a file processing method and device, and the method comprises the steps: obtaining a module file in a firmware interface system and an entry address of the module file during operation, carrying out the compiling and decompiling of the module file, and obtaining a source code instruction employing an assembly language corresponding to the module file, wherein the source code instruction carries a corresponding address offset, and processing the source code instruction into a source code instruction with link information according to the entry address and the address offset, so that a module file is automatically processed to obtain the source code instruction with the link information, and therefore, the problem that a real environment cannot be completely simulated during debugging on a virtual machine is avoided, so that developers are helped to quickly and directly find the actual running address of the code of each module file, and the problems such as crash at a certain address and the like can be accurately positioned.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a file processing method, a file processing device, an electronic device and a readable storage medium. Background technique [0002] UEFI (Unified Extensible Firmware Interface, Unified Extensible Firmware Interface) is a personal computer system specification used to define the software interface between the operating system and system firmware, as a substitute for BIOS (BasicInput Output System, Basic Input Output System) Program. The extensible firmware interface is responsible for power-on self-test, contacting the operating system, and providing an interface connecting the operating system and hardware. [0003] In UEFI, many programs are not a complete executable file, they are divided into some relatively independent module files, for example, DLL (Dynamic Link Library, dynamic link library) files. The entry address of each module is dynamically loaded when it...

Problems solved by technology

[0006] The technical problem to be solved by the embodiments of the present invention is to provide a file processing method, device, electronic equipment, and readable storage medium, so as to solve the problem that it is difficult to find the address where the code of each module actually runs, and thus it is difficult to locate the cause of the crash.
