Problems solved by technology

[0004] Traditional breakpoint setting methods and disadvantages: 1. Starting from the initial breakpoint, manually analyze according to experience, and gradually set the subsequent breakpoint position
The disadvantage is that the time cost is extremely high, it can only be used in the debugging of local program fragments, and the breakpoint setting of the full path coverage of the program cannot be realized

Abstract

The invention provides a breakpoint setting method based on a program running process, electronic equipment and a storage medium, and the breakpoint setting method comprises the following steps: scanning a disassembling file of a to-be-run program, identifying all branch node types, setting related branch node instruction information according to an instruction set system architecture, and setting the disassembling file of the to-be-run program according to the related branch node instruction information. Obtaining an initial jump table recording all branch node information; analyzing the initial jump table, and executing a preset instruction to set a breakpoint table; and when the program is scheduled to a running state, sequentially setting breakpoint addresses for preset instructions according to the breakpoint table and the fixed breakpoint interval granularity, and / or modifying the breakpoint interval granularity through the instructions, adjusting the breakpoint address of the branch node and updating the breakpoint table when a certain branch node is detected to have no fault. In this way, full-automatic analysis in the software verification process can be achieved, only one-time configuration needs to be carried out on the instruction set architecture, and the operation efficiency of the program can be effectively improved.

Description

technical field [0001] The present disclosure relates to the technical field of program debugging, and in particular, to a method for setting a breakpoint based on a program running process, an electronic device and a storage medium. Background technique [0002] The debugger can stop program execution at will, mainly in software breakpoints and hardware breakpoints. A software breakpoint is embodied as a breakpoint instruction added to the program, and the program execution stops when the breakpoint instruction is reached (ie, a software interrupt). [0003] In the software verification process of the chip, especially when large-scale software is used as a benchmark and automatic testing technology is used, it is usually necessary to quickly locate the fault point in the program flow for analysis and verification. To locate faults, you need to export on-site information. When the processor hardware does not have a Trace module, you need to suspend and set breakpoints when ...
