CG_ANNOTATE(1)                    cg_annotate                   CG_ANNOTATE(1)



NAME
       cg_annotate - post-processing tool for Cachegrind

SYNOPSIS
       cg_annotate [options] cachegrind-out-file [source-files...]

DESCRIPTION
       cg_annotate takes one or more Cachegrind output files and prints data
       about the profiled program in an easy-to-read form.

OPTIONS
       -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.
