-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,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%]
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
--show-percs=<no|yes> [default: yes]
When enabled, a percentage is printed next to all event
counts. This helps gauge the relative importance of each
function and line.
--auto=<no|yes> [default: yes]
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.
