Automatic positioning method and device of compiler error

Abstract

The invention discloses an automatic positioning method and device of a compiler error. The method comprises the following steps of: compiling a source file of an executable program by using the compiler: generating a correct first executable code by using a standard complier and generating a second executable code by using a complier to be error-positioned; reading-in the first executable code and the second executable code by using a program loading tool to finish operation of a first executable program corresponding to the first executable code and a second executable program corresponding to the second executable code; controlling to select functions from the first executable program and the second executable program by using the program loading tool, and realizing positioning of an error function in the second executable program by using a dichotomy and a substitution method. According to the automatic positioning method and device disclosed by the invention, the error can be positioned to be in a function class, the function in the executable codes is directly subjected to error positioning, and the error positioning time is shorter.

Description

technical field [0001] The invention relates to the technical field of compiler development and testing, more specifically, to a method and device for automatically locating compiler errors. Background technique [0002] In the development process of the compiler, the compiler is usually tested by using large-scale application software (for example: SPEC benchmark test package). However, the code volume of large-scale application software is very large, and the number of functions involved is hundreds or even thousands. Once a problem with the compiler causes an error in the application software, it is very time-consuming to locate the problem, and it is difficult to locate the error location and the compiler that caused the error. Quickly locate the cause. Therefore, how to quickly locate the running error is an urgent problem to be solved in the development process of the compiler. [0003] The compilation process of the compiler can be roughly divided into: lexical anal...

AI Technical Summary

Problems solved by technology

[0008] 1. Some errors are not caused by a specific optimization of the compiler. At this time, the correct object code set cannot be compiled by adjusting the options. The solution is to use the standard compiler (such as GCC) in the system to generate the correct object code. collection, but after being located in a file, it is impossible to further locate specific functions in the same source file;

[0009] 2. The processing time is slow: the pre-preparation work is more complicated, and the target file set and the function set in the file need to be prepared first. The automatic positioning tool needs to be relinked every time it is processed to generate a new executable program.
