Subject: [BUGFIX PATCH 5/6] perf/probe: Fix to show inlined function callsite without entry_pc
Date: Fri, 25 Oct 2019 17:47:01 +0900
Message-ID: <157199322107.8075.12659099000567865708.stgit@devnote2> (raw)
In-Reply-To: <157199317547.8075.1010940983970397945.stgit@devnote2>

Fix perf-probe --line option to show inlined function callsite
lines even if the function DIE has only ranges.

Without this,
  # tools/perf/perf probe -L amd_put_event_constraints
  ...
      2  {
      3         if (amd_has_nb(cpuc) && amd_is_nb_event(&event->hw))
                        __amd_put_nb_event_constraints(cpuc, event);
      5  }

With this patch,
  # tools/perf/perf probe -L amd_put_event_constraints
  ...
      2  {
      3         if (amd_has_nb(cpuc) && amd_is_nb_event(&event->hw))
      4                 __amd_put_nb_event_constraints(cpuc, event);
      5  }
