Recombining method and device for transplantable executive file

Abstract

The invention discloses a recombining method and device for a transplantable executive file. The method comprises the following steps: reading a functional logic sequence in an original transplantable executive file; obtaining an invoking record of the functional logic sequence; generating a ranking position by adopting the invoking record; and recombining the functional logic sequence according to the ranking position to obtain the target transplantable executive file. According to the method and the device, the invoking record of the functional logic position of the transplantable executive file is obtained to generate the ranking position, and then the functional logic position is recombined according to the ranking position, so that a CPU (Central Processing Unit) can directly read the functional logic position in memory to avoid the frequent reading of a disk by the CPU, reduce the consumption of system resources and reduce the generation of missing page interruption, so that the cold start speed of application programs is increased.

Description

technical field [0001] The present invention relates to the technical field of data optimization, in particular to a method for reorganizing a portable executable file and a device for reorganizing a portable executable file. Background technique [0002] A file is some binary data stored continuously on a computer disk. For different operating systems, the format of its executable file is different. Under Win9x, Win NT / 2000 / XP, the format of the 32-bit executable file is PE (Portable Executable, portable executable file). For example, under the Windows platform, Win32 executable files, such as *.EXE, *.DLL, *.OBJ, *.COX, etc., are all in PE format. [0003] Compilation of executable files is the translation process from source code (usually high-level language) to object code (usually low-level language or machine language) that can be directly executed by a computer or virtual machine. Typical compiler output is an object file consisting of the machine code containing t...

Problems solved by technology

However, the disorder of function symbols will cause the frequency of such page fault interrupts to be much higher than the actual number of times required. Since the speed of the hard disk is much slower than that of the memory, frequent reading of the hard disk seriously affects the startup speed.

In addition, frequent reading of code from hard disk to memory will also increase the memory usage of executable files (such as browsers) when they are running.
