套件：uftrace（0.9.0-1）
Traces and analyzes execution of programs written in C/C++
The uftrace tool is intended for tracing and analyzing the execution of programs written in C or C++. It was heavily inspired by the ftrace framework of the Linux kernel (especially the function graph tracer) and supports userspace programs. It supports various kinds of commands and filters to help analysis of the program's execution and performance.
It traces each function in the executable and shows time durations. It can also trace external library calls - but only entry and exit are supported, and internal function calls within the library cannot be traced unless the library itself was built with profiling enabled.
It can show detailed execution flow at function level, and report which function has the highest overhead. It also shows various information related to the execution environment.
You can setup filters to exclude or include specific functions when tracing. In addition, function arguments and return values can be saved and shown later.
The uftrace tool supports multi-process and/or multi-threaded applications. It can also trace kernel functions as well, with root privileges and if the system enables the function graph tracer in the kernel (CONFIG_FUNCTION_GRAPH_TRACER=y).
