cg_annotate - post-processing tool for Cachegrind
cg_annotate [options] cachegrind-out-file [source-files...]
takes an output file produced by the Valgrind tool Cachegrind and prints the information in an easy-to-read form.
Show the help message.
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
file (and use the order in the file). Useful if you want to concentrate on, for example, I cache misses (--show=I1mr,I2mr), or data read misses (--show=D1mr,D2mr), or L2 data misses (--show=D2mr,D2mw). Best used in conjunction with
--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
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 L2 read misses or 1% of L2 write misses, use this option:
--auto=<no|yes> [default: no]
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
options can be given to add multiple directories.
