Description Frank Ch. Eigler 2023-08-03 18:50:42 UTC 
The cob= / ob= outputs in the callgrind format include file names to identify the programs that were profiled.
It would be handy if another field could also include the elf buildid of those binaries, so that callgrind files could become more portable / timeless, wherein they don't require the exact same file versions to be installed.  Instead consumer tools could consult debuginfod or similar to fetch the correct executable/debuginfo/source code, by their unique buildid.
