Abstract

The invention relates to a method and system for obtaining a program symbol table. The method includes: extracting symbol table information in program debugging information, storing the symbol table information in a symbol table source file; compiling the symbol table source file to generate a symbol table dynamic link library; running the program and loading the symbol Table dynamic link library, get the program symbol table. The present invention does not need manual search to obtain the symbol table, and does not increase the space of the program at the same time, which effectively solves the problem that the existing program symbol table acquisition method causes the program to occupy a large space and the acquisition efficiency is low, saves the program running space, and improves the efficiency of the program. In order to obtain the efficiency of the symbol table.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and system for obtaining a program symbol table. Background technique [0002] In computer science, a symbol table is a data structure used in language translators such as compilers and interpreters. In a symbol table, each identifier in a program's source code is bound to its declaration or usage information, such as its data type, scope, and memory address. The symbol table needs to continuously collect, record and use relevant information such as the types and characteristics of some grammatical symbols in the source program during the process of compiling the program. This information is generally stored in the system in the form of tables. Such as constant table, variable name table, array name table, process name table, label table, etc., collectively referred to as symbol table. The quality of the symbol table organization, construction and management methods will dire...
