Subject: [BUGFIX PATCH 0/3] perf/probe: Fix available line bugs
Date: Thu, 24 Oct 2019 18:12:27 +0900	[thread overview]
Message-ID: <157190834681.1859.7399361844806238387.stgit@devnote2> (raw)

Hi,

Here are some bugfixes related to showing available line (--line/-L)
option. I found that gcc generated some subprogram DIE with only
range attribute but no entry_pc or low_pc attributes.
In that case, perf probe failed to show the available lines in that
subprogram (function). To fix that, I introduced some bugfixes to
handle such cases correctly.

Thank you,
