@c ----------------------------------------------------------------------------

@ManPageStart{DESCRIPTION}
@c man begin DESCRIPTION

Reads the @file{gmon.out} file and the profiled executable.  With the
executable, we can reconstruct information about the profiled symbols
and the memory map layout.  The @file{gmon.out} file provides details
about the execution duration for each symbol, as well as data used to
build the call graph.  The profile data is taken from the call graph
profile file (@file{gmon.out} default) which is created by programs
that are compiled with profile arches (i.e., the @samp{-pg} option of
@code{cc}).

For example, this command converts the profile data (@file{gmon.out})
for an executable called @samp{a.out} and stores the data collected in
an experiment directory with the name @samp{example.er}.

@smallexample
$ gprofng display gmon -o example.er ./a.out gmon.out
@end smallexample

@ManPageStart{OPTIONS}
@c man begin OPTIONS

@table @gcctabopt

@item --version
@ifclear man
@IndexSubentry{Options, @code{--version}}
@end ifclear

Print the version number and exit.

@item --help
@ifclear man
@IndexSubentry{Options, @code{--help}}
@end ifclear

Print usage information and exit.

@item -o @var{<exp_name>}
@ifclear man
@IndexSubentry{Options, @code{-o}}
@end ifclear

Specify the name for the experiment directory.  The name has to end with
@samp{.er} and may contain an absolute path (e.g. @file{/tmp/experiment.er}).
An existing experiment with the same name will not be overwritten.

@item -O @var{<exp_name>}
@ifclear man
@IndexSubentry{Options, @code{-O}}
@end ifclear

This is the same as the @samp{-o} option, but unlike this option, silently
overwrites an existing experiment directory with the same name.

@c NOTES section

@ManPageStart{NOTES}
@c man begin NOTES

Any executable in the ELF (Executable and Linkable Format) object
format can be used for profiling with gprofng.  If @var{target} is
missing, the default executable name is @file{a.out}.  If
@var{gmon-file} is missing, the default profile data file name is
@file{gmon.out}.

The user guide for gprofng is maintained as a Texinfo manual.  If the
@command{info} and @command{gprofng} programs are correctly installed, the
command @command{info gprofng} should give access to this document.
