Embodiment Construction

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] In the prior art, an ELF file only includes a code segment and a data segment, and does not include data type metadata information. At the same time, the current ELF file does not contain the metadata of the data type expressing the target data, and the host program has no way to realize the preloading of the program module.

Abstract

The invention provides an ELF file generation method containing data type information of target data, an ELF file, equipment and a storage medium. The ELF file comprises at least one data segment anda metadata segment corresponding to the data segment. Target data is stored in the data segment; wherein metadata describing the data type of the target data is stored in the metadata segment. By adding and storing the data segment containing the metadata describing the data type of the target data into the existing ELF file, the data type description information of the type data of the program module needing to be dynamically obtained can be preloaded, and therefore preloading of the program module can be achieved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to an ELF generating method including data type information of target data, an ELF file including data type information of target data, equipment and a storage medium. Background technique [0002] ELF format file In computer science, is a format file used for binaries, executables, object code, shared libraries, and core dumps. The ELF format file was developed and released by the UNIX System Laboratory (USL) as the Application Binary Interface (ABI), and it is also the main executable file format of Linux. [0003] ELF file consists of 4 parts, namely ELF header (ELF header), program header table (Program header table), section (Section) and section header table (Section header table). In fact, not all of the content is necessarily contained in one file, nor are they necessarily arranged as shown. [0004] Currently, development programs are all modularized, and it is ne...
