Either add a field for the directory to that struct (the directory is
in the debug info, you can see it at the end of assembly.ll) or
configure your kcachegrind to access those directories. I don't have it
at hand currently but it's sth. like View -> Settings -> Directory
Settings for Source Annotation.


Kind regards,
