(Although column widths are automatically minimised, a wide terminal is clearly useful.)
Each source file is clearly marked (
User-annotated source
) as having been chosen manually for annotation.
If the file was found in one of the directories specified with the
-I
/
--include
option, the directory and file are both
given.
Each line is annotated with its event counts. Events not applicable for a line are represented by a dot. This is useful
for distinguishing between an event which cannot happen, and one which can but did not.
Sometimes only a small section of a source file is executed. To minimise uninteresting output, Cachegrind only shows
annotated lines and lines within a small distance of annotated lines. Gaps are marked with the line numbers so you
know which part of a file the shown code comes from, eg:
