CG_ANNOTATE

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:

--sort=D2mr:99,D2mw:99

--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 -I/--include options can be given to add multiple directories.
