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,
