--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.
