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.

Specifies the events upon which the sorting of the function-by-function entries will be based.

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

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.

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.

Adds a directory to the list in which to search for files. Multiple -I/--include options can be given to add multiple directories.
