PROGRAM:

NAME

opannotate - produce source or assembly annotated with profile data

SYNOPSIS

opannotate [ options ] [profile specification]

DESCRIPTION

opannotate outputs annotated source and/or assembly from profile data of an OProfile
session. See oprofile(1) for how to write profile specifications.

OPTIONS

--assembly / -a
Output annotated assembly. The binary file to be annotated does not need full
debugging information to use this option, but symbol information is required.
Without symbol information, opannotate will silently refuse to annotate the binary.
If this option is combined with --source, then mixed source / assembly annotations
are output.

--demangle / -D none|smart|normal
none: no demangling. normal: use default demangler (default) smart: use pattern-
matching to make C++ symbol demangling more readable.

--exclude-dependent / -x
Do not include application-specific images for libraries, kernel modules and the
kernel. This option only makes sense if the profile session used --separate.

--exclude-file [files]
Exclude all files in the given comma-separated list of glob patterns. This option
is supported solely with the --source option. It can be used to filter out source
files in the output using the following types of specifications:

· filenames (basename -- i.e., no path)

· filename glob specifications (all files whose base filename matches the given
pattern)

· directory segments (all source files located in the specified directory; e.g.
"libio")

· directory segment glob specifications (e.g., "libi*")

--exclude-symbols / -e [symbols]
Exclude all the symbols in the given comma-separated list.

--help / -? / --usage
Show help message.

--image-path / -p [paths]
Comma-separated list of additional paths to search for binaries. This is needed to
find modules in kernels 2.6 and upwards.

--root / -R [path]
A path to a filesystem to search for additional binaries.

--include-file [files]
Only include files in the given comma-separated list of glob patterns. The same
rules apply for this option as for the --exclude-file option.

--merge / -m [lib,cpu,tid,tgid,unitmask,all]
Merge any profiles separated in a --separate session.

--include-symbols / -i [symbols]
Only include symbols in the given comma-separated list.

--objdump-params [params]
Pass the given parameters as extra values when calling objdump. If more than one
option is to be passed to objdump, the parameters must be enclosed in a quoted
string.

An example of where this option is useful is when your toolchain does not
automatically recognize instructions that are specific to your processor. For
example, on IBM POWER7/RHEL 6, objdump must be told that a binary file may have
POWER7-specific instructions. The opannotate option to show the POWER7-specific
instructions is:
--objdump-params=-Mpower7

The opannotate option to show the POWER7-specific instructions, the source code
(--source) and the line numbers (-l) would be:
--objdump-params="-Mpower7 -l --source"

--output-dir / -o [dir]
Output directory. This makes opannotate output one annotated file for each source
file. This option can't be used in conjunction with --assembly.

--search-dirs / -d [paths]
Comma-separated list of paths to search for source files. You may need to use this
option when the debug information for an image contains relative paths.

--base-dirs / -b [paths]
Comma-separated list of paths to strip from debug source files, prior to looking
for them in --search-dirs.

--session-dir=dir_path
Use sample database from the specified directory dir_path instead of the default
location. If --session-dir is not specified, then opannotate will search for
samples in <current_dir>/oprofile_data first. If that directory does not exist, the
standard session-dir of /var/lib/oprofile is used.

--source / -s
Output annotated source. This requires debugging information to be available for
the binaries.

--threshold / -t [percentage]
For annotated assembly, only output data for symbols that have more than the given
percentage of total samples. For profiles using multiple events, if the threshold
is reached for any event, then all sample data for the symbol is shown.

For annotated source, only output data for source files that have more than the
given percentage of total samples. For profiles using multiple events, if the
threshold is reached for any event, then all sample data for the source file is
shown.

--verbose / -V [options]
Give verbose debugging output.

--version / -v
Show version.
