.SH DESCRIPTION
.IX Header "DESCRIPTION"
The GNU \fBsize\fR utility lists the section sizes and the total
size for each of the binary files \fIobjfile\fR on its argument list.
By default, one line of output is generated for each file or each
module if the file is an archive.
.PP
\&\fIobjfile\fR... are the files to be examined.  If none are
specified, the file \f(CW\*(C`a.out\*(C'\fR will be used instead.
.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\-G\fR 4
.IX Item "-G"
.IP \fB\-\-format=\fR\fIcompatibility\fR 4
.IX Item "--format=compatibility"
.PD
Using one of these options, you can choose whether the output from GNU
\&\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.  Alternatively, you can choose the GNU format output
(using \fB\-G\fR, or \fB\-\-format=gnu\fR), this is similar to
Berkeley's output format, but sizes are counted differently.
.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
The Berkeley style output counts read only data in the \f(CW\*(C`text\*(C'\fR
column, not in the \f(CW\*(C`data\*(C'\fR column, the \f(CW\*(C`dec\*(C'\fR and \f(CW\*(C`hex\*(C'\fR
columns both display the sum of the \f(CW\*(C`text\*(C'\fR, \f(CW\*(C`data\*(C'\fR, and
\&\f(CW\*(C`bss\*(C'\fR columns in decimal and hexadecimal respectively.
.Sp
The GNU format counts read only data in the \f(CW\*(C`data\*(C'\fR column, not
the \f(CW\*(C`text\*(C'\fR column, and only displays the sum of the \f(CW\*(C`text\*(C'\fR,
\&\f(CW\*(C`data\*(C'\fR, and \f(CW\*(C`bss\*(C'\fR columns once, in the \f(CW\*(C`total\*(C'\fR column.
The \fB\-\-radix\fR option can be used to change the number base for
all columns.  Here is the same data displayed with GNU conventions:
.Sp
.Vb 4
\&        $ size \-\-format=GNU ranlib size
\&              text       data        bss      total filename
\&            279880      96920      11592     388392 ranlib
\&            279880      96920      11888     388688 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
\&        .data          81920       303104
\&        .bss           11592       385024
\&        Total         388392
\&        
\&        
\&        size  :
\&        section         size         addr
\&        .text         294880         8192
\&        .data          81920       303104
\&        .bss           11888       385024
\&        Total         388688

.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\-\-common\fR 4
.IX Item "--common"
Print total size of common symbols in each file.  When using Berkeley
or GNU format these are included in the bss size.
.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 or GNU format 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\-V\fR 4
.IX Item "-V"
.IP \fB\-\-version\fR 4
.IX Item "--version"
.PD
Display the version number of \fBsize\fR.
.IP \fB\-f\fR 4
.IX Item "-f"
Ignored.  This option is used by other versions of the \fBsize\fR
program, but it is not supported by the GNU Binutils version.
.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.
