cg_annotate - post-processing tool for Cachegrind
cg_annotate [options] cachegrind-out-file
[source-files...]
cg_annotate takes one or more Cachegrind output files and
prints data about the profiled program in an easy-to-read form.
-h --help
Show the help message.
--version
Show the version number.
--diff
Diff two Cachegrind output files.
--mod-filename <regex> [default: none]
Specifies an s/old/new/ search-and-replace
expression that is applied to all filenames. Useful when differencing, for
removing minor differences in paths between two different versions of a
program that are sitting in different directories. An i suffix makes
the regex case-insensitive, and a g suffix makes it match multiple
times.
--mod-funcname <regex> [default: none]
Like --mod-filename, but for filenames. Useful for
removing minor differences in randomized names of auto-generated functions
generated by some compilers.
--show=A,B,C [default: all, using order in the Cachegrind
output file]
Specifies which events to show (and the column order).
Default is to use all present in the Cachegrind output file (and use the order
in the file). Best used in conjunction with --sort.
--sort=A,B,C [default: order in the Cachegrind output file]
Specifies the events upon which the sorting of the
file:function and function:file entries will be based.
--threshold=X [default: 0.1%]
Sets the significance threshold for the file:function and
function:files sections. A file or function is shown if it accounts for more
than X% of the counts for the primary sort event. If annotating source files,
this also affects which files are annotated.
--show-percs, --no-show-percs, --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.
--annotate, --no-annotate, --auto=<no|yes> [default: yes]
Enables or disables source file annotation.
--context=N [default: 8]
The number of lines of context to show before and after
each annotated line. Use a large number (e.g. 100000) to show all source
lines.
