gcc - 如何从 gprof 输出中排除内容？

Question

我正在尝试分析我拥有的应用程序，但我不希望与 UI（在 wxWidgets 中制作）相关的任何内容出现在 gprof 的调用图中等。我该怎么做？

Answer 1

从 gprof 手册页：

   -E name
          suppresses the displaying of the graph profile entry for routine
          name  (and  its descendants) as -e, above, and also excludes the
          time spent in name (and its descendants) from the total and per-
          centage  time  computations.  (For example, -E mcount and all of
          the other monitor(3) routines are excluded by default.)
