Select loops (by file and line number) for deeper analysis.

GUI Equivalent

Survey >




<string> is a comma-separated list of files/line numbers in the following format: file1:line1.


No default argument

Actions Modified



Selecting loops of interest can decrease collection overhead.

Do not confuse the mark-up-loops action with the mark-up-list action option. The mark-up-loops action coupled with the select action option enables a GUI checkbox; therefore loop selection persists beyond the duration of the mark-up-loops action and applies to downstream analyses, such as Dependencies and Memory Access Patterns analyses. The collect action coupled with the mark-up-list action option simulates enabling a GUI checkbox; therefore loop selection persists only for the duration of the collect action.


  1. Run a Survey analysis to identify loops of interest.

  2. Select those loops for deeper analysis.
