CG_ANNOTATE(1) Release 3.5.0 CG_ANNOTATE(1)
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,I2mr), or data read misses (--show=D1mr,D2mr), or L2 data misses (--show=D2mr,D2mw). 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: 99%] Sets the threshold for the function-by-function summary. Functions are shown that account for more than X% of 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 the functions that cover 99% of L2 read misses and 99% 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 couldnt 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.
