--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%]
--auto=<no|yes> [default: no]
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:
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.
