Problems solved by technology

This method has the following problems: when each subroutine or most of the subroutines are debugged, the optimized target code of each subroutine is gradually jumped to the debuggable target code until all jump to the debuggable target code Debugging the target code, correspondingly, the running speed of the program will become slower and slower; in addition, using this method, both versions of the target code need to be loaded into the memory, which will greatly consume memory resources

Abstract

An optimized version of a binary and a non-optimized debuggable version of a binary for each compiling unit in the source code program are generated. The optimized versions of binaries of all compiling units are loaded into memory for debugging, which is monitored. In response to determining that a first compiling unit in the source code program is to be debugged, the non-optimized debuggable version of the binary is loaded into a memory location that was previously used by the optimized version of the binary. In response to determining that debugging of a second compiling unit in the source code program is to be cancelled, the optimized version of the binary of the second compiling unit is loaded into a memory location that was previously used by the non-optimized debuggable version of the binary.

Description

technical field [0001] The present invention relates to program debugging, in particular, the present invention relates to a method and system for dynamically switching codes in the debugging process. Background technique [0002] When programming, most applications are debugged at the source code level. The source code is generally written in a high-level language, and the high-level language is mainly compared to the assembly language. It is a programming that is closer to natural language and mathematical formulas. It is basically separated from the hardware system of the machine and written in a way that is easier for people to understand. program. Therefore, the programmer's debugging operations such as stepping, setting breakpoints, etc. are based on the high-level language source code view. However, in fact, what the debugger receives, runs, and operates is the binary code (binary) (compiled version of the source code) of the program to generate the running result. ...
