Comment (by Roland Haas):

You may also find useful suggested options on https://software.intel.com/content/www/us/en/develop/documentation/vtune-help/top/set-up-analysis-target/linux-targets/compiler-switches-for-performance-analysis-on-linux-targets.html where eg -parallel-source-info=2 would be one option that they recommend but that the ET’s option lists would typically not set (we tend to set -g and -O2 is the Intel compiler’s default).
