The menu.rc and loader.rc files will now be replaced during
upgrades. Please migrate local changes to menu.rc.local and
loader.rc.local instead.

GNU Binutils versions of addr2line, c++filt, nm, readelf, size,
strings and strip have been removed. The src.conf(5) knob
WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools.
20150728:
As ZFS requires more kernel stack pages than is the default on some
architectures e.g. i386, it now warns if KSTACK_PAGES is less than
ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing).
Please consider using 'options KSTACK_PAGES=X' where X is greater
than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations.

Instead, a pointer to the entry with the new information should be

.Sh DESCRIPTION
The
.Nm
utility creates and maintains groups of files combined into an
archive.
Once an archive has been created, new files can be added to it, and
existing files can be extracted, deleted or replaced.
.Pp
Files are named in the archive by their last file name component,
so if a file referenced by a path containing a
.Dq /
is archived, it will be named by the last component of the path.
Similarly when matching paths listed on the command line against
file names stored in the archive, only the last component of the
path will be compared.
.Pp
The normal use of
.Nm
is for the creation and maintenance of libraries suitable for use
with the link editor
.Xr ld 1 ,
although it is not restricted to this purpose.
The
.Nm
utility can create and manage an archive symbol table (see
.Xr ar 5 )
used to speed up link editing operations.
If a symbol table is present in an archive, it will be
kept up-to-date by subsequent operations on the archive.
.Sh OPTIONS
The
.Nm
utility supports the following options:
.Bl -tag -width indent
.It Fl a Ar member-after
When used with option
.Fl m
this option specifies that the archive members specified by
arguments
.Ar
are moved to after the archive member named by argument
.Ar member-after .
When used with option
.Fl r
this option specifies that the files specified by arguments
.Ar
are added after the archive member named by argument
.Ar member-after .
.It Fl b Ar member-before
When used with option
.Fl m
this option specifies that the archive members specified by
arguments
.Ar
are moved to before the archive member named by argument
.Ar member-before .
When used with option
.Fl r
this option specifies that the files specified by arguments
.Ar
are added before the archive member named by argument
.Ar member-before .
.It Fl c
Suppress the informational message printed when a new archive is
created using the
.Fl r
and
.Fl q
options.
.It Fl C
Prevent extracted files from replacing like-named files
in the file system.
.It Fl d
Delete the members named by arguments
.Ar
from the archive specified by argument
.Ar archive .
The archive's symbol table, if present, is updated to reflect
the new contents of the archive.
.It Fl D
When used in combination with the
.Fl r
or
.Fl q
option, insert 0's instead of the real mtime, uid and gid values
and 0644 instead of file mode from the members named by arguments
.Ar .
This ensures that checksums on the resulting archives are reproducible
when member contents are identical.
.It Fl f
Synonymous with option
.Fl T .
.It Fl F Ar flavor | Fl -flavor Ar flavor
Create archives with the specified archive format.
Legal values for argument
.Ar flavor
are:
.Bl -tag -width indent -compact
.It Ar bsd
Create BSD format archives.
.It Ar gnu
An alias for
.Ar svr4 .
.It Ar svr4
Create SVR4 format archives.
.El
If this option is not specified,
.Nm
will create archives using the SVR4 format.
.It Fl i Ar member-before
Synonymous with option
.Fl b .
.It Fl j
This option is accepted for compatibility with the
.Tn FreeBSD
version of the
.Nm
utility, but is ignored.
.It Fl l
This option is accepted for compatibility with GNU
.Xr ar 1 ,
but is ignored.
.It Fl m
Move archive members specified by arguments
.Ar
within the archive.
If a position has been specified by one of the
.Fl a ,
.Fl b
or
.Fl i
options, the members are moved to before or after the specified
position.
If no position has been specified, the specified members are moved
to the end of the archive.
If the archive has a symbol table, it is updated to reflect the
new contents of the archive.
.It Fl M
Read and execute MRI librarian commands from standard input.
The commands understood by the
.Nm
utility are described in the section
.Sx "MRI Librarian Commands" .
.It Fl o
Preserve the original modification times of members when extracting
them.
.It Fl p
Write the contents of the specified archive members named by
arguments
.Ar
to standard output.
If no members were specified, the contents of all the files in the
archive are written in the order they appear in the archive.
.It Fl q
Append the files specified by arguments
.Ar
to the archive specified by argument
.Ar archive
without checking if the files already exist in the archive.
The archive symbol table will be updated as needed.
If the file specified by the argument
.Ar archive
does not already exist, a new archive will be created.
.It Fl r
Replace (add) the files specified by arguments
.Ar
in the archive specified by argument
.Ar archive ,
creating the archive if necessary.
Replacing existing members will not change the order of members within
the archive.
If a file named in arguments
.Ar
does not exist, existing members in the archive that match that
name are not changed.
New files are added to the end of the archive unless one of the
positioning options
.Fl a ,
.Fl b
or
.Fl i
is specified.
The archive symbol table, if it exists, is updated to reflect the
new state of the archive.
.It Fl s
Add an archive symbol table (see
.Xr ar 5 )
to the archive specified by argument
.Ar archive .
Invoking
.Nm
with the
.Fl s
option alone is equivalent to invoking
.Xr ranlib 1 .
.It Fl S
Do not generate an archive symbol table.
.It Fl t
For
.Nm ,
list the files specified by arguments
.Ar
in the order in which they appear in the archive, one per line.
If no files are specified, all files in the archive are listed.
.It Fl T
Use only the first fifteen characters of the archive member name or
command line file name argument when naming archive members.
.It Fl u
Conditionally update the archive or extract members.
When used with the
.Fl r
option, files named by arguments
.Ar
will be replaced in the archive if they are newer than their
archived versions.
When used with the
.Fl x
option, the members specified by arguments
.Ar
will be extracted only if they are newer than the corresponding
files in the file system.
.It Fl v
Provide verbose output.
When used with the
.Fl d ,
.Fl m ,
.Fl q
or
.Fl x
options,
.Nm
gives a file-by-file description of the archive modification being
performed, which consists of three white-space separated fields:
the option letter, a dash
.Dq "-" ,
and the file name.
When used with the
.Fl r
option,
.Nm
displays the description as above, but the initial letter is an
.Dq a
if the file is added to the archive, or an
.Dq r
if the file replaces a file already in the archive.
When used with the
.Fl p
option, the name of the file enclosed in
.Dq <
and
.Dq >
characters is written to standard output preceded by a single newline
character and followed by two newline characters.
The contents of the named file follow the file name.
When used with the
.Fl t
option,
.Nm
displays eight whitespace separated fields:
the file permissions as displayed by
.Xr strmode 3 ,
decimal user and group IDs separated by a slash (
.Dq / Ns ) ,
the file size in bytes, the file modification time in
.Xr strftime 3
format
.Dq "%b %e %H:%M %Y" ,
and the name of the file.
.It Fl V
Print a version identifier and exit.
.It Fl x
Extract archive members specified by arguments
.Ar
into the current directory.
If no members have been specified, extract all members of the archive.
If the file corresponding to an extracted member does not exist it
will be created.
If the file corresponding to an extracted member does exist, its owner
and group will not be changed while its contents will be overwritten
and its permissions will set to that entered in the archive.
The file's access and modification time would be that of the time
of extraction unless the
.Fl o
option was specified.
.It Fl z
This option is accepted for compatibility with the
.Tn FreeBSD
version of the
.Nm
utility, but is ignored.
.El
.Ss "MRI Librarian Commands"
If the
.Fl M
option is specified, the
.Nm
utility will read and execute commands from its standard input.
If standard input is a terminal, the
.Nm
utility will display the prompt
.Dq Li "AR >"
before reading a line, and will continue operation even if errors are
encountered.
If standard input is not a terminal, the
.Nm
utility will not display a prompt and will terminate execution on
encountering an error.
.Pp
Each input line contains a single command.
Words in an input line are separated by whitespace characters.
The first word of the line is the command, the remaining words are
the arguments to the command.
The command word may be specified in either case.
Arguments may be separated by commas or blanks.
.Pp
Empty lines are allowed and are ignored.
Long lines are continued by ending them with the
.Dq Li +
character.
.Pp
The
.Dq Li *
and
.Dq Li "\;"
characters start a comment.
Comments extend till the end of the line.
.Pp
When executing an MRI librarian script the
.Nm
utility works on a temporary copy of an archive.
Changes to the copy are made permanent using the
.Ic save
command.
.Pp
Commands understood by the
.Nm
utility are:
.Bl -tag -width indent
.It Ic addlib Ar archive | Ic addlib Ar archive Pq Ar member Oo Li , Ar member Oc Ns ...
Add the contents of the archive named by argument
.Ar archive
to the current archive.
If specific members are named using the arguments
.Ar member ,
then those members are added to the current archive.
If no members are specified, the entire contents of the archive
are added to the current archive.
.It Ic addmod Ar member Oo Li , Ar member Oc Ns ...
Add the files named by arguments
.Ar member
to the current archive.
.It Ic clear
Discard all the contents of the current archive.
.It Ic create Ar archive
Create a new archive named by the argument

Delete the modules named by the arguments
.Ar member
from the current archive.
.It Ic directory Ar archive Po Ar member Oo Li , Ar member Oc Ns ... Pc Op Ar outputfile
List each named module in the archive.
The format of the output depends on the verbosity setting set using
the
.Ic verbose
command.
Output is sent to standard output, or to the file specified by
argument
.Ar outputfile .
.It Ic end
Exit successfully from the
.Nm
utility.
Any unsaved changes to the current archive will be discarded.

.Sh NAME
.Nm ar
.Nd archive file format for
.Xr ar 1
and
.Xr ranlib 1
.Sh SYNOPSIS
.In ar.h
.Sh DESCRIPTION
.Xr ar 1
archives are created and managed by the
.Xr ar 1
and
.Xr ranlib 1
utilities.
These archives are typically used during program development to
hold libraries of program objects.
An
.Xr ar 1
archive is contained in a single operating system file.
.Pp
This manual page documents two variants of the
.Xr ar 1
archive format: the BSD archive format, and the SVR4/GNU archive
format.
.Pp
In both variants the archive file starts with an identifying byte
sequence of the seven ASCII characters
.Sq Li "!<arch>"
followed by a ASCII linefeed character
.Po
see the constant
.Dq ARMAG
in the header file
.In ar.h
.Pc .
.Pp
Archive members follow the initial identifying byte sequence.
Each archive member is prefixed by a fixed size header describing the
file attributes associated with the member.
.Ss "Archive Headers"
An archive header describes the file attributes for the archive member that
follows it.
The
.Xr ar 5
format only supports a limited number of attributes: the file name,
the file creation time stamp, the uid and gid of the creator, the file
mode and the file size.
.Pp
Archive headers are placed at an even byte offset in the archive file.
If the data for an archive member ends at an odd byte offset, then a
padding byte with value 0x0A is used to position the next archive
header on an even byte offset.
.Pp
An archive header comprises the following fixed sized fields:
.Bl -tag -width "Li ar_name"
.It Ar ar_name
(16 bytes) The file name of the archive member.
The format of this field varies between the BSD and SVR4/GNU formats and
is described in more detail in the section
.Sx "Representing File Names"
below.
.It Ar ar_date
(12 bytes) The file modification time for the member in seconds since the
epoch, encoded as a decimal number.
.It Ar ar_uid
(6 bytes) The uid associated with the archive member, encoded as a
decimal number.
.It Ar ar_gid
(6 bytes) The gid associated with the archive member, encoded as a
decimal number.
.It Ar ar_mode
(8 bytes) The file mode for the archive member, encoded as an octal
number.
.It Ar ar_size
(10 bytes) In the SVR4/GNU archive format this field holds the size in
bytes of the archive member, encoded as a decimal number.
In the BSD archive format, for short file names, this field
holds the size in bytes of the archive member, encoded as a decimal
number.
For long file names
.Po
see
.Sx "Representing File Names"
below
.Pc ,
the field contains the combined size of the
archive member and its file name, encoded as a decimal number.
.It Ar ar_fmag
(2 bytes) This field holds 2 bytes with values 0x96 and 0x0A
respectively, marking the end of the header.
.El
.Pp
Unused bytes in the fields of an archive header are set to the value
0x20.
.Ss "Representing File Names"
The BSD and SVR4/GNU variants use different schemes for encoding file
names for members.
.Bl -tag -width "SVR4/GNU"
.It "BSD"
File names that are up to 16 bytes long and which do not contain
embedded spaces are stored directly in the
.Ar ar_name
field of the archive header.
File names that are either longer than 16 bytes or which contain
embedded spaces are stored immediately after the archive header
and the
.Ar ar_name
field of the archive header is set to the string
.Dq "#1/"
followed by a decimal representation of the number of bytes needed for
the file name.
In addition, the
.Ar ar_size
field of the archive header is set to the decimal representation of
the combined sizes of the archive member and the file name.
The file contents of the member follows the file name without further
padding.
.Pp
As an example, if the file name for a member was
.Dq "A B"
and its contents was the string
.Dq "C D" ,
then the
.Ar ar_name
field of the header would contain
.Dq Li "#1/3" ,
the
.Ar ar_size
field of the header would contain
.Dq Li 6 ,
and the bytes immediately following the header would be 0x41, 0x20,
0x42, 0x43, 0x20 and 0x44
.Po
ASCII
.Dq "A BC D"
.Pc .
.It "SVR4/GNU"
File names that are up to 15 characters long are stored directly in the
.Ar ar_name
field of the header, terminated by a
.Dq Li /
character.
.Pp
If the file name is larger than would fit in space for the
.Ar ar_name
field, then the actual file name is kept in the archive
string table
.Po
see
.Sx "Archive String Tables"
below
.Pc ,
and the decimal offset of the file name in the string table is stored
in the
.Ar ar_name
field, prefixed by a
.Dq Li /
character.
.Pp
As an example, if the real file name has been stored at offset 768 in
the archive string table, the
.Ar ar_name
field of the header will contain the string
.Dq /768 .
.El
.Ss "Special Archive Members"
The following archive members are special.
.Bl -tag -width indent
.It Dq Li /
In the SVR4/GNU variant of the archive format, the archive member with
name
.Dq Li /
denotes an archive symbol table.
If present, this member will be the very first member in the
archive.
.It Dq Li //
In the SVR4/GNU variant of the archive format, the archive member with
name
.Dq Li //
denotes the archive string table.
This special member is used to hold filenames that do not fit in the
file name field of the header
.Po
see
.Sx "Representing File Names"
above
.Pc .
If present, this member immediately follows the archive symbol table
if an archive symbol table is present, or is the first member otherwise.
.It Dq Li "__.SYMDEF"
This special member contains the archive symbol table in the BSD
variant of the archive format.
If present, this member will be the very first member in the
archive.
.El
.Ss "Archive String Tables"
An archive string table is used in the SVR4/GNU archive format to hold
file names that are too large to fit into the constraints of the
.Ar ar_name
field of the archive header.
An archive string table contains a sequence of file names.
Each file name in the archive string table is terminated by the
byte sequence 0x2F, 0x0A
.Po
the ASCII string
.Dq "/\en"
.Pc .
No padding is used to separate adjacent file names.
.Ss "Archive Symbol Tables"
Archive symbol tables are used to speed up link editing by providing a
mapping between the program symbols defined in the archive
and the corresponding archive members.
Archive symbol tables are managed by the
.Xr ranlib 1
utility.
.Pp
The format of archive symbol tables is as follows:
.Bl -tag -width "SVR4/GNU"
.It BSD
In the BSD archive format, the archive symbol table comprises
of two parts: a part containing an array of
.Vt "struct ranlib"
descriptors, followed by a part containing a symbol string table.
The sizes and layout of the structures that make up a BSD format
archive symbol table are machine dependent.
.Pp
The part containing
.Vt "struct ranlib"
descriptors begins with a field containing the size in bytes of the
array of
.Vt "struct ranlib"
descriptors encoded as a C
.Vt long
value.
.Pp
The array of
.Vt "struct ranlib"
descriptors follows the size field.
Each
.Vt "struct ranlib"
descriptor describes one symbol.
.Pp
A
.Vt "struct ranlib"
descriptor comprises two fields:
.Bl -tag -width "Ar ran_strx" -compact
.It Ar ran_strx
.Pq C Vt long
This field contains the zero-based offset of the symbol name in the
symbol string table.
.It Ar ran_off
.Pq C Vt long
This field is the file offset to the archive header for the archive
member defining the symbol.
.El
.Pp
The part containing the symbol string table begins with a field
containing the size in bytes of the string table, encoded as a C
.Vt long
value.
This string table follows the size field, and contains
NUL-terminated strings for the symbols in the symbol table.
.It SVR4/GNU
In the SVR4/GNU archive format, the archive symbol table starts with a
4-byte binary value containing the number of entries contained in the
archive symbol table.
This count of entries is stored most significant byte first.
.Pp
Next, there are
.Ar count
4-byte numbers, each stored most significant byte first.
Each number is a binary offset to the archive header for the member in
the archive file for the corresponding symbol table entry.
.Pp
After the binary offset values, there are
.Ar count
NUL-terminated strings in sequence, holding the symbol names for
the corresponding symbol table entries.
.El
.Sh STANDARDS COMPLIANCE
The
.Xr ar 1
archive format is not currently specified by a standard.
.Pp
This manual page documents the
.Xr ar 1
archive formats used by the
.Bx 4.4
and
.Ux SVR4
operating system releases.

.Sh NAME
.Nm ranlib
.Nd update archive symbol tables
.Sh SYNOPSIS
.Nm
.Op Fl D
.Op Fl t
.Ar archive Ns ...
.Nm
.Fl V
.Sh DESCRIPTION
The
.Nm ranlib
utility is used to update an existing archive symbol table in an
.Xr ar 1
archive, or to add an archive symbol table to an archive lacking one.
.Sh OPTIONS
The
.Nm
utility supports the following options:
.Bl -tag -width indent
.It Fl D
Use zeros for the mtime, uid and gid fields, and use mode 0644 for the
file mode field for all archive member headers.
This ensures that checksums on the resulting archives are reproducible
when member contents are identical.
.It Fl t
This option is accepted, but is ignored.
.It Fl V
Print a version identifier and exit.
.El
.Sh EXAMPLES
To update the archive symbol table for an archive
.Pa lib.a ,
use:
.Dl "ranlib lib.a"
.Sh DIAGNOSTICS
.Ex -std
.Sh SEE ALSO
.Xr ar 1 ,
.Xr ld 1 ,
.Xr archive 3 ,
.Xr elf 3 ,
.Xr ar 5
.Sh HISTORY
The
.Nm
command first appeared in AT&T UNIX Version 7.
.Pp
In
.Fx 8.0 ,
.An Kai Wang Aq Mt kaiw@FreeBSD.org
reimplemented
.Nm
using the
.Lb libarchive
and the
.Lb libelf .

.Sh NAME
.Nm brandelf
.Nd mark an ELF binary for a specific ABI
.Sh SYNOPSIS
.Nm
.Op Fl V | Fl -version
.Op Fl f Ar ELF_ABI_number
.Op Fl h | Fl -help
.Op Fl l
.Op Fl t Ar brand
.Op Fl v
.Ar
.Sh DESCRIPTION
The
.Nm
utility marks an ELF binary to be run under a certain ABI.
.Pp
The options are as follows:
.Bl -tag -width indent
.It Fl f Ar ELF_ABI_number
Forces branding with the supplied ELF ABI number.
Incompatible with the
.Fl t
option.
These values are assigned by SCO/USL.
.It Fl h | Fl -help
Print a usage message and exit.
.It Fl l
Writes the list of all known ELF types to standard output.
.It Fl t Ar brand
Brands the given ELF binaries to be of the ABI specified by argument
.Ar brand .
Supported ABIs include
.Dq Li 86Open ,
.Dq Li AIX ,
.Dq Li ARM ,
.Dq Li AROS ,
.Dq Li FreeBSD ,
.Dq Li GNU ,
.Dq Li HP/UX ,
.Dq Li Hurd ,
.Dq Li IRIX ,
.Dq Li Linux
(an alias for
.Dq Li GNU ) ,
.Dq Li Modesto ,
.Dq Li NSK ,
.Dq Li NetBSD ,
.Dq Li None ,
.Dq Li OpenBSD ,
.Dq Li OpenVMS ,
.Dq Li Standalone ,
.Dq Li SVR4
(an alias for
.Dq Li None ) ,
.Dq Li Solaris
and
.Dq Li Tru64 .
.It Fl v
This option is accepted for compatibility with other versions of
.Nm ,
but is otherwise ignored.
.It Fl V | Fl -version
Print a version identifier and exit.
.El
.Pp
If the options
.Fl f Ar ELF_ABI_number
or
.Fl t Ar brand
were specified,
.Nm
will brand the files named by command-line arguments
.Ar
to be of type
.Ar ELF_ABI_number
or
.Ar brand
respectively.
.Pp
If neither of the
.Fl f
or
.Fl t
options were specified,
.Nm
will display the current branding for the files named by the arguments
.Ar .
.Sh EXIT STATUS
Exit status is 0 on success, and 1 if the command
fails if a file does not exist, is too short, fails to brand properly,
or the brand requested is not one of the known types and the
.Fl f
option is not set.
.Sh EXAMPLES
The following is an example of a typical usage
of the
.Nm
command:
.Bd -literal -offset indent
brandelf file
brandelf -t GNU file

.IX Header "DESCRIPTION"
\&\fBaddr2line\fR translates addresses into file names and line numbers.
Given an address in an executable or an offset in a section of a relocatable
object, it uses the debugging information to figure out which file name and
line number are associated with it.
.PP
The executable or relocatable object to use is specified with the \fB\-e\fR
option. The default is the file \fIa.out\fR. The section in the relocatable
object to use is specified with the \fB\-j\fR option.
.PP
\&\fBaddr2line\fR has two modes of operation.
.PP
In the first, hexadecimal addresses are specified on the command line,
and \fBaddr2line\fR displays the file name and line number for each
address.
.PP
In the second, \fBaddr2line\fR reads hexadecimal addresses from
standard input, and prints the file name and line number for each
address on standard output. In this mode, \fBaddr2line\fR may be used
in a pipe to convert dynamically chosen addresses.
.PP
The format of the output is \fB\s-1FILENAME:LINENO\s0\fR. The file name and
line number for each address is printed on a separate line. If the
\&\fB\-f\fR option is used, then each \fB\s-1FILENAME:LINENO\s0\fR line is
preceded by a \fB\s-1FUNCTIONNAME\s0\fR line which is the name of the function
containing the address.
.PP
If the file name or function name can not be determined,
\&\fBaddr2line\fR will print two question marks in their place. If the
line number can not be determined, \fBaddr2line\fR will print 0.

If the address belongs to a function that was inlined, the source
information for all enclosing scopes back to the first non-inlined
function will also be printed. For example, if \f(CW\*(C`main\*(C'\fR inlines
\&\f(CW\*(C`callee1\*(C'\fR which inlines \f(CW\*(C`callee2\*(C'\fR, and address is from
\&\f(CW\*(C`callee2\*(C'\fR, the source information for \f(CW\*(C`callee1\*(C'\fR and \f(CW\*(C`main\*(C'\fR
will also be printed.

.IP "\fB@\fR\fIfile\fR" 4
.IX Item "@file"
Read command-line options from \fIfile\fR. The options read are
inserted in place of the original @\fIfile\fR option. If \fIfile\fR
does not exist, or cannot be read, then the option will be treated
literally, and not removed.
.Sp
Options in \fIfile\fR are separated by whitespace. A whitespace
character may be included in an option by surrounding the entire
option in either single or double quotes. Any character (including a
backslash) may be included by prefixing the character to be included
with a backslash. The \fIfile\fR may itself contain additional
@\fIfile\fR options; any such options will be processed recursively.

\&\s-1GNU\s0 \fBnm\fR lists the symbols from object files \fIobjfile\fR....
If no object files are listed as arguments, \fBnm\fR assumes the file
\&\fIa.out\fR.
.PP
For each symbol, \fBnm\fR shows:
.IP "\(bu" 4
The symbol value, in the radix selected by options (see below), or
hexadecimal by default.
.IP "\(bu" 4
The symbol type. At least the following types are used; others are, as
well, depending on the object file format. If lowercase, the symbol is
local; if uppercase, the symbol is global (external).
.RS 4
.ie n .IP """A""" 4
.el .IP "\f(CWA\fR" 4
.IX Item "A"
The symbol's value is absolute, and will not be changed by further
linking.
.ie n .IP """B""" 4
.el .IP "\f(CWB\fR" 4

The symbol is in the uninitialized data section (known as \s-1BSS\s0).
.ie n .IP """C""" 4
.el .IP "\f(CWC\fR" 4
.IX Item "C"
The symbol is common. Common symbols are uninitialized data. When
linking, multiple common symbols may appear with the same name. If the
symbol is defined anywhere, the common symbols are treated as undefined
references.
.ie n .IP """D""" 4
.el .IP "\f(CWD\fR" 4
.IX Item "D"
The symbol is in the initialized data section.
.ie n .IP """G""" 4
.el .IP "\f(CWG\fR" 4
.IX Item "G"
The symbol is in an initialized data section for small objects. Some
object file formats permit more efficient access to small data objects,
such as a global int variable as opposed to a large global array.
.ie n .IP """I""" 4
.el .IP "\f(CWI\fR" 4
.IX Item "I"
The symbol is an indirect reference to another symbol. This is a \s-1GNU\s0
extension to the a.out object file format which is rarely used.
.ie n .IP """N""" 4
.el .IP "\f(CWN\fR" 4
.IX Item "N"
The symbol is a debugging symbol.
.ie n .IP """R""" 4
.el .IP "\f(CWR\fR" 4
.IX Item "R"
The symbol is in a read only data section.
.ie n .IP """S""" 4
.el .IP "\f(CWS\fR" 4
.IX Item "S"
The symbol is in an uninitialized data section for small objects.
.ie n .IP """T""" 4

.IX Item "T"
The symbol is in the text (code) section.
.ie n .IP """U""" 4
.el .IP "\f(CWU\fR" 4
.IX Item "U"
The symbol is undefined.
.ie n .IP """V""" 4
.el .IP "\f(CWV\fR" 4
.IX Item "V"
The symbol is a weak object. When a weak defined symbol is linked with
a normal defined symbol, the normal defined symbol is used with no error.
When a weak undefined symbol is linked and the symbol is not defined,
the value of the weak symbol becomes zero with no error.
.ie n .IP """W""" 4
.el .IP "\f(CWW\fR" 4
.IX Item "W"
The symbol is a weak symbol that has not been specifically tagged as a
weak object symbol. When a weak defined symbol is linked with a normal
defined symbol, the normal defined symbol is used with no error.
When a weak undefined symbol is linked and the symbol is not defined,
the value of the symbol is determined in a system-specific manner without
error. On some systems, uppercase indicates that a default value has been
specified.
.ie n .IP """\-""" 4

.IX Item "-"
The symbol is a stabs symbol in an a.out object file. In this case, the

Display the dynamic symbols rather than the normal symbols. This is
only meaningful for dynamic objects, such as certain types of shared
libraries.
.IP "\fB\-f\fR \fIformat\fR" 4
.IX Item "-f format"
.PD 0
.IP "\fB\-\-format=\fR\fIformat\fR" 4
.IX Item "--format=format"
.PD
Use the output format \fIformat\fR, which can be \f(CW\*(C`bsd\*(C'\fR,
\&\f(CW\*(C`sysv\*(C'\fR, or \f(CW\*(C`posix\*(C'\fR. The default is \f(CW\*(C`bsd\*(C'\fR.
Only the first character of \fIformat\fR is significant; it can be
either upper or lower case.
.IP "\fB\-g\fR" 4
.IX Item "-g"
.PD 0
.IP "\fB\-\-extern\-only\fR" 4
.IX Item "--extern-only"
.PD
Display only external symbols.
.IP "\fB\-l\fR" 4
.IX Item "-l"
.PD 0
.IP "\fB\-\-line\-numbers\fR" 4
.IX Item "--line-numbers"
.PD
For each symbol, use debugging information to try to find a filename and
line number. For a defined symbol, look for the line number of the
address of the symbol. For an undefined symbol, look for the line
number of a relocation entry which refers to the symbol. If line number
information can be found, print it after the other symbol information.
.IP "\fB\-n\fR" 4
.IX Item "-n"
.PD 0
.IP "\fB\-v\fR" 4
.IX Item "-v"
.IP "\fB\-\-numeric\-sort\fR" 4
.IX Item "--numeric-sort"
.PD
Sort symbols numerically by their addresses, rather than alphabetically
by their names.
.IP "\fB\-p\fR" 4
.IX Item "-p"
.PD 0
.IP "\fB\-\-no\-sort\fR" 4
.IX Item "--no-sort"
.PD
Do not bother to sort the symbols in any order; print them in the order
encountered.
.IP "\fB\-P\fR" 4
.IX Item "-P"
.PD 0
.IP "\fB\-\-portability\fR" 4
.IX Item "--portability"
.PD
Use the \s-1POSIX\s0.2 standard output format instead of the default format.
Equivalent to \fB\-f posix\fR.
.IP "\fB\-S\fR" 4
.IX Item "-S"
.PD 0
.IP "\fB\-\-print\-size\fR" 4
.IX Item "--print-size"
.PD
Print size, not the value, of defined symbols for the \f(CW\*(C`bsd\*(C'\fR output format.
.IP "\fB\-s\fR" 4
.IX Item "-s"
.PD 0
.IP "\fB\-\-print\-armap\fR" 4
.IX Item "--print-armap"
.PD
When listing symbols from archive members, include the index: a mapping
(stored in the archive by \fBar\fR or \fBranlib\fR) of which modules
contain definitions for which names.
.IP "\fB\-r\fR" 4
.IX Item "-r"
.PD 0
.IP "\fB\-\-reverse\-sort\fR" 4
.IX Item "--reverse-sort"
.PD
Reverse the order of the sort (whether numeric or alphabetic); let the
last come first.
.IP "\fB\-\-size\-sort\fR" 4
.IX Item "--size-sort"
Sort symbols by size. The size is computed as the difference between
the value of the symbol and the value of the symbol with the next higher
value. If the \f(CW\*(C`bsd\*(C'\fR output format is used the size of the symbol
is printed, rather than the value, and \fB\-S\fR must be used in order
both size and value to be printed.
.IP "\fB\-\-special\-syms\fR" 4
.IX Item "--special-syms"
Display symbols which have a target-specific special meaning. These
symbols are usually used by the target for some special processing and
are not normally helpful when included included in the normal symbol
lists. For example for \s-1ARM\s0 targets this option would skip the mapping
symbols used to mark transitions between \s-1ARM\s0 code, \s-1THUMB\s0 code and
data.
.IP "\fB\-t\fR \fIradix\fR" 4
.IX Item "-t radix"
.PD 0
.IP "\fB\-\-radix=\fR\fIradix\fR" 4
.IX Item "--radix=radix"
.PD
Use \fIradix\fR as the radix for printing the symbol values. It must be
\&\fBd\fR for decimal, \fBo\fR for octal, or \fBx\fR for hexadecimal.
.IP "\fB\-\-target=\fR\fIbfdname\fR" 4
.IX Item "--target=bfdname"
Specify an object code format other than your system's default format.
.IP "\fB\-u\fR" 4
.IX Item "-u"
.PD 0
.IP "\fB\-\-undefined\-only\fR" 4
.IX Item "--undefined-only"
.PD
Display only undefined symbols (those external to each object file).
.IP "\fB\-\-defined\-only\fR" 4
.IX Item "--defined-only"
Display only defined symbols for each object file.
.IP "\fB\-V\fR" 4
.IX Item "-V"
.PD 0
.IP "\fB\-\-version\fR" 4
.IX Item "--version"
.PD
Show the version number of \fBnm\fR and exit.
.IP "\fB\-X\fR" 4
.IX Item "-X"
This option is ignored for compatibility with the \s-1AIX\s0 version of
\&\fBnm\fR. It takes one parameter which must be the string
\&\fB32_64\fR. The default mode of \s-1AIX\s0 \fBnm\fR corresponds
to \fB\-X 32\fR, which is not supported by \s-1GNU\s0 \fBnm\fR.
.IP "\fB\-\-help\fR" 4
.IX Item "--help"
Show a summary of the options to \fBnm\fR and exit.
.IP "\fB@\fR\fIfile\fR" 4
.IX Item "@file"
Read command-line options from \fIfile\fR. The options read are
inserted in place of the original @\fIfile\fR option. If \fIfile\fR
does not exist, or cannot be read, then the option will be treated
literally, and not removed.
.Sp
Options in \fIfile\fR are separated by whitespace. A whitespace
character may be included in an option by surrounding the entire
option in either single or double quotes. Any character (including a
backslash) may be included by prefixing the character to be included
with a backslash. The \fIfile\fR may itself contain additional
@\fIfile\fR options; any such options will be processed recursively.

\&\fBreadelf\fR displays information about one or more \s-1ELF\s0 format object
files. The options control what particular information to display.
.PP
\&\fIelffile\fR... are the object files to be examined. 32\-bit and
64\-bit \s-1ELF\s0 files are supported, as are archives containing \s-1ELF\s0 files.
.PP
This program performs a similar function to \fBobjdump\fR but it
goes into more detail and it exists independently of the \s-1BFD\s0
library, so if there is a bug in \s-1BFD\s0 then readelf will not be
affected.

Don't break output lines to fit into 80 columns. By default
\&\fBreadelf\fR breaks section header and segment listing lines for
64\-bit \s-1ELF\s0 files, so that they fit into 80 columns. This option causes
\&\fBreadelf\fR to print each section header resp. each segment one a
single line, which is far more readable on terminals wider than 80 columns.

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \s-1GNU\s0 \fBsize\fR utility lists the section sizes\-\-\-and the total
size\-\-\-for each of the object or archive files \fIobjfile\fR in its
argument list. By default, one line of output is generated for each
object file or each module in an archive.
.PP
\&\fIobjfile\fR... are the object files to be examined.
If none are specified, the file \f(CW\*(C`a.out\*(C'\fR will be used.
.SH "OPTIONS"
.IX Header "OPTIONS"
The command line options have the following meanings:
.IP "\fB\-A\fR" 4
.IX Item "-A"
.PD 0
.IP "\fB\-B\fR" 4
.IX Item "-B"
.IP "\fB\-\-format=\fR\fIcompatibility\fR" 4
.IX Item "--format=compatibility"
.PD
Using one of these options, you can choose whether the output from \s-1GNU\s0
\&\fBsize\fR resembles output from System V \fBsize\fR (using \fB\-A\fR,
or \fB\-\-format=sysv\fR), or Berkeley \fBsize\fR (using \fB\-B\fR, or
\&\fB\-\-format=berkeley\fR). The default is the one-line format similar to
Berkeley's.
.Sp
Here is an example of the Berkeley (default) format of output from
\&\fBsize\fR:
.Sp
.Vb 4
\& $ size \-\-format=Berkeley ranlib size
\& text data bss dec hex filename
\& 294880 81920 11592 388392 5ed28 ranlib
\& 294880 81920 11888 388688 5ee50 size
.Ve
.Sp
This is the same data, but displayed closer to System V conventions:
.Sp
.Vb 7
\& $ size \-\-format=SysV ranlib size
\& ranlib :
\& section size addr
\& .text 294880 8192

\& .text 294880 8192
\& .data 81920 303104
\& .bss 11888 385024
\& Total 388688
.Ve
.IP "\fB\-\-help\fR" 4
.IX Item "--help"
Show a summary of acceptable arguments and options.
.IP "\fB\-d\fR" 4
.IX Item "-d"
.PD 0
.IP "\fB\-o\fR" 4
.IX Item "-o"
.IP "\fB\-x\fR" 4
.IX Item "-x"
.IP "\fB\-\-radix=\fR\fInumber\fR" 4
.IX Item "--radix=number"
.PD
Using one of these options, you can control whether the size of each
section is given in decimal (\fB\-d\fR, or \fB\-\-radix=10\fR); octal
(\fB\-o\fR, or \fB\-\-radix=8\fR); or hexadecimal (\fB\-x\fR, or
\&\fB\-\-radix=16\fR). In \fB\-\-radix=\fR\fInumber\fR, only the three
values (8, 10, 16) are supported. The total size is always given in two
radices; decimal and hexadecimal for \fB\-d\fR or \fB\-x\fR output, or
octal and hexadecimal if you're using \fB\-o\fR.
.IP "\fB\-t\fR" 4
.IX Item "-t"
.PD 0
.IP "\fB\-\-totals\fR" 4
.IX Item "--totals"
.PD
Show totals of all objects listed (Berkeley format listing mode only).
.IP "\fB\-\-target=\fR\fIbfdname\fR" 4
.IX Item "--target=bfdname"
Specify that the object-code format for \fIobjfile\fR is
\&\fIbfdname\fR. This option may not be necessary; \fBsize\fR can
automatically recognize many formats.
.IP "\fB\-V\fR" 4
.IX Item "-V"
.PD 0
.IP "\fB\-\-version\fR" 4
.IX Item "--version"
.PD
Display the version number of \fBsize\fR.
.IP "\fB@\fR\fIfile\fR" 4
.IX Item "@file"
Read command-line options from \fIfile\fR. The options read are
inserted in place of the original @\fIfile\fR option. If \fIfile\fR
does not exist, or cannot be read, then the option will be treated
literally, and not removed.
.Sp
Options in \fIfile\fR are separated by whitespace. A whitespace
character may be included in an option by surrounding the entire
option in either single or double quotes. Any character (including a
backslash) may be included by prefixing the character to be included
with a backslash. The \fIfile\fR may itself contain additional
@\fIfile\fR options; any such options will be processed recursively.

existing file. When this argument is used, only one \fIobjfile\fR

.PD 0
.IP "\fB\-\-wildcard\fR" 4
.IX Item "--wildcard"
.PD
Permit regular expressions in \fIsymbolname\fRs used in other command
line options. The question mark (?), asterisk (*), backslash (\e) and
square brackets ([]) operators can be used anywhere in the symbol
name. If the first character of the symbol name is the exclamation
point (!) then the sense of the switch is reversed for that symbol.
For example:
.Sp
.Vb 1
\& \-w \-K !foo \-K fo*
.Ve
.Sp
would cause strip to only keep symbols that start with the letters
\&\*(L"fo\*(R", but to discard the symbol \*(L"foo\*(R".
.IP "\fB\-x\fR" 4
.IX Item "-x"
.PD 0
.IP "\fB\-\-discard\-all\fR" 4
.IX Item "--discard-all"

Remove non-global symbols.
.IP "\fB\-X\fR" 4
.IX Item "-X"
.PD 0
.IP "\fB\-\-discard\-locals\fR" 4
.IX Item "--discard-locals"
.PD
Remove compiler-generated local symbols.
(These usually start with \fBL\fR or \fB.\fR.)
.IP "\fB\-\-keep\-file\-symbols\fR" 4
.IX Item "--keep-file-symbols"
When stripping a file, perhaps with \fB\-\-strip\-debug\fR or
\&\fB\-\-strip\-unneeded\fR, retain any symbols specifying source file names,
which would otherwise get stripped.
.IP "\fB\-\-only\-keep\-debug\fR" 4
.IX Item "--only-keep-debug"
Strip a file, removing contents of any sections that would not be
stripped by \fB\-\-strip\-debug\fR and leaving the debugging sections
intact. In \s-1ELF\s0 files, this preserves all note sections in the output.
.Sp
The intention is that this option will be used in conjunction with
\&\fB\-\-add\-gnu\-debuglink\fR to create a two part executable. One a
stripped binary which will occupy less space in \s-1RAM\s0 and in a
distribution and the second a debugging information file which is only
needed if debugging abilities are required. The suggested procedure
to create these files is as follows:
.RS 4
.IP "1.<Link the executable as normal. Assuming that it is called>" 4
.IX Item "1.<Link the executable as normal. Assuming that it is called>"
\&\f(CW\*(C`foo\*(C'\fR then...

.el .IP "1.<Run \f(CWobjcopy \-\-only\-keep\-debug foo foo.dbg\fR to>" 4
.IX Item "1.<Run objcopy --only-keep-debug foo foo.dbg to>"
create a file containing the debugging info.
.ie n .IP "1.<Run ""objcopy \-\-strip\-debug foo"" to create a>" 4
.el .IP "1.<Run \f(CWobjcopy \-\-strip\-debug foo\fR to create a>" 4

.el .IP "1.<Run \f(CWobjcopy \-\-add\-gnu\-debuglink=foo.dbg foo\fR>" 4
.IX Item "1.<Run objcopy --add-gnu-debuglink=foo.dbg foo>"
to add a link to the debugging info into the stripped executable.
.RE
.RS 4
.Sp
Note \- the choice of \f(CW\*(C`.dbg\*(C'\fR as an extension for the debug info
file is arbitrary. Also the \f(CW\*(C`\-\-only\-keep\-debug\*(C'\fR step is
optional. You could instead do this:
.IP "1.<Link the executable as normal.>" 4
.IX Item "1.<Link the executable as normal.>"
.PD 0
.ie n .IP "1.<Copy ""foo"" to ""foo.full"">" 4
.el .IP "1.<Copy \f(CWfoo\fR to \f(CWfoo.full\fR>" 4
.IX Item "1.<Copy foo to foo.full>"
.ie n .IP "1.<Run ""strip \-\-strip\-debug foo"">" 4
.el .IP "1.<Run \f(CWstrip \-\-strip\-debug foo\fR>" 4
.IX Item "1.<Run strip --strip-debug foo>"
.ie n .IP "1.<Run ""objcopy \-\-add\-gnu\-debuglink=foo.full foo"">" 4
.el .IP "1.<Run \f(CWobjcopy \-\-add\-gnu\-debuglink=foo.full foo\fR>" 4
.IX Item "1.<Run objcopy --add-gnu-debuglink=foo.full foo>"
.RE
.RS 4
.PD
.Sp
ie the file pointed to by the \fB\-\-add\-gnu\-debuglink\fR can be the
full executable. It does not have to be a file created by the
\&\fB\-\-only\-keep\-debug\fR switch.
.Sp
Note \- this switch is only intended for use on fully linked files. It
does not make sense to use it on object files where the debugging
information may be incomplete. Besides the gnu_debuglink feature
currently only supports the presence of one filename containing
debugging information, not multiple filenames on a one-per-object-file
basis.
.RE
.IP "\fB\-V\fR" 4

Verbose output: list all object files modified. In the case of
archives, \fBstrip \-v\fR lists all members of the archive.
.IP "\fB@\fR\fIfile\fR" 4
.IX Item "@file"
Read command-line options from \fIfile\fR. The options read are
inserted in place of the original @\fIfile\fR option. If \fIfile\fR
does not exist, or cannot be read, then the option will be treated
literally, and not removed.
.Sp
Options in \fIfile\fR are separated by whitespace. A whitespace
character may be included in an option by surrounding the entire
option in either single or double quotes. Any character (including a
backslash) may be included by prefixing the character to be included
with a backslash. The \fIfile\fR may itself contain additional
@\fIfile\fR options; any such options will be processed recursively.
