CG_ANNOTATE(1)                 cg_annotate                CG_ANNOTATE(1)

NAME         top

       cg_annotate - post-processing tool for Cachegrind

SYNOPSIS         top


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

DESCRIPTION         top

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

OPTIONS         top

       -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.
