Many-core architecture-oriented gdb debugger automatic test technology

Abstract

The invention discloses a many-core architecture-oriented gdb debugger automatic test technology. Based on a heterogeneous many-core processor, the technology comprises the following steps: S1, deploying a test program and a gdbinit file; S2, starting an automatic test script, traversing all test programs under the test directory by the automatic test script, and recording a real-time running state of the debugger into a debugging log; S3, when the test script runs, starting a background program, monitoring the running time of the test program, comparing the recorded running time of the test program with a set time threshold, if the running time of the test program is less than or equal to the time threshold, continuing to execute the next test program, and if the running time of the testprogram is greater than the time threshold, judging that the test program is hooked; S4, outputting debugging logs. According to the invention, the problem of long-time stagnation of the debugger caused by the fact that a test program is hooked in the test process of the gdb debugger is solved, the operation is simple and convenient, the consumed manpower and hardware resources are less, the efficiency is higher, and the stability is good.

Description

technical field [0001] The invention belongs to the technical field of optimization of heterogeneous many-core processors, and in particular relates to an automatic testing technology of a gdb debugger oriented to many-core architecture. Background technique [0002] While the heterogeneous many-core processor has become the mainstream architecture of high-performance computing, which provides convenience for the fast running of parallel programs, it also puts forward higher requirements for the debugging support of heterogeneous many-core programs. However, due to the complex structure of many-core processors, and as the scale of parallel programs becomes larger and more complex, the gdb debugger often produces some unexpected problems during use, and some occasional errors often It takes a lot of manpower and time to find out, which makes the gdb function test on many-core processors face severe challenges. [0003] At present, most of the function tests of the gdb debugg...
