NAME
       cg_annotate - post-processing tool for Cachegrind

SYNOPSIS
       cg_annotate [options] cachegrind-out-file [source-files...]

DESCRIPTION
       cg_annotate takes an output file produced by the Valgrind tool Cachegrind
       and prints the information in an easy-to-read form.

OPTIONS
       -h --help
           Show the help message.

       --version
           Show the version number.

       --show=A,B,C [default: all, using order in cachegrind.out.<pid>]
           Specifies which events to show (and the column order). Default is to
           use all present in the cachegrind.out.<pid> file (and use the order
           in the file). Useful if you want to concentrate on, for example, I
           cache misses (--show=I1mr,ILmr), or data read misses
           (--show=D1mr,DLmr), or LL data misses (--show=DLmr,DLmw). Best used
           in conjunction with --sort.

       --sort=A,B,C [default: order in cachegrind.out.<pid>]
           Specifies the events upon which the sorting of the
           function-by-function entries will be based.

       --threshold=X [default: 0.1%]
           Sets the threshold for the function-by-function summary. A function
           is shown if it accounts for more than X% of the counts for the
           primary sort event. If auto-annotating, also affects which files are
           annotated.

           Note: thresholds can be set for more than one of the events by
           appending any events for the --sort option with a colon and a number
           (no spaces, though). E.g. if you want to see each function that
           covers more than 1% of LL read misses or 1% of LL write misses, use
           this option:

           --sort=DLmr:1,DLmw:1

       --show-percs=<no|yes> [default: yes]
           When enabled, a percentage is printed next to all event counts. This
           helps gauge the relative importance of each function and line.

       --auto=<no|yes> [default: yes]
           When enabled, automatically annotates every file that is mentioned in
           the function-by-function summary that can be found. Also gives a list
           of those that couldn't be found.

       --context=N [default: 8]
           Print N lines of context before and after each annotated line. Avoids
           printing large sections of source files that were not executed. Use a
           large number (e.g. 100000) to show all source lines.

       -I<dir> --include=<dir> [default: none]
           Adds a directory to the list in which to search for files. Multiple
           -I/--include options can be given to add multiple directories.
