Program modification method and device

Abstract

The present invention provides a program modification method and device, the method comprising: executing a preset program modification script to obtain a target program file; searching the target program file defined as A target pointer in the first expression form of a preset number of digits, wherein the preset number of digits is smaller than the actual number of digits assigned to the target pointer by the target operating system when the target program is executed by the target operating system; The representation of the target pointer is replaced with a second representation that supports the target operating system. In this way, the automatic modification of the target program file is realized, the efficiency of program modification is improved, and the error rate of program modification is reduced.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for modifying a program. Background technique [0002] With the development of electronic terminal hardware technology, the capability of CPU processors is getting stronger and stronger, and CPUs with higher numbers of digits are more widely used in electronic devices. However, for some applications developed with a lower-digit (such as 32-bit) system as the standard, the code in it is solidified that storing a memory address is a lower-digit number (such as 32-bit), and allocates memory address space When , the allocated memory address is also a lower number of digits (such as 32 bits). When these programs run in a higher-digit (such as 64-bit) system, the system will allocate a higher-digit (such as 64-bit) memory address, then the program will generate an error, resulting in data interception, causing the high-order data to be lost. This results i...

Problems solved by technology

When these programs run in a higher-digit (such as 64-bit) system, the system will allocate a higher-digit (such as 64-bit) memory address, then the program will generate an error, resulting in data interception, causing the high-order data to be lost. resulting in a memory access exception

At this time, it is necessary to modify the data in the program file. For a program file with a lot of program code and a large magnitude, if you manually modify all the memory access codes in the code, it will be very time-consuming and labor-intensive, and manual modification is easy. Mistakes generate modification errors that affect the normal operation of the program
