.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
|
||
|
|

|
||
|
|
.Ve
|
||
|
|
.Sp
|
||
|
|
This is the same data, but displayed closer to System V conventions:
|
||
|
|
.Sp
|
||
|
|
.Vb 7
|
||
|
|
\& $ size \-\-format=SysV ranlib size

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.

|

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.

|

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.
