Release 3.24.0                                     03/19/2025                                     CG_ANNOTATE(1)

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,usingorderintheCachegrindoutputfile]
           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:orderintheCachegrindoutputfile]
           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.
