|
|
|
<p>The <small>GNU</small> <code>size</code> utility lists the section sizes—and the total
|
size—for each of the object or archive files <var>objfile</var> in its
|
argument list. By default, one line of output is generated for each
|
object file or each module in an archive.
|
</p>
|
<p><var>objfile</var>… are the object files to be examined.
|
If none are specified, the file <code>a.out</code> will be used.
|
</p>
|
|
|
<p>The command line options have the following meanings:
|
</p>
|
<dl compact="compact">
|
<dt><code>-A</code></dt>
|
<dt><code>-B</code></dt>
|
<dt><code>--format=<var>compatibility</var></code></dt>
|
<dd><a name="index-size-display-format"></a>
|
<p>Using one of these options, you can choose whether the output from <small>GNU</small>
|
<code>size</code> resembles output from System V <code>size</code> (using <samp>-A</samp>,
|
or <samp>--format=sysv</samp>), or Berkeley <code>size</code> (using <samp>-B</samp>, or
|
<samp>--format=berkeley</samp>). The default is the one-line format similar to
|
Berkeley’s.
|
</p>
|
<p>Here is an example of the Berkeley (default) format of output from
|
<code>size</code>:
|
</p><div class="smallexample">
|
<pre class="smallexample">$ size --format=Berkeley ranlib size
|
text data bss dec hex filename
|
294880 81920 11592 388392 5ed28 ranlib
|
294880 81920 11888 388688 5ee50 size
|
</pre></div>
|
|
<p>This is the same data, but displayed closer to System V conventions:
|
</p>
|
<div class="smallexample">
|
<pre class="smallexample">$ size --format=SysV ranlib size
|
ranlib :
|
section size addr

|
|
|

</pre></div>

</dd>

<dt><code>--help</code></dt>

<dt><code>--radix=<var>number</var></code></dt>
|
<dd><a name="index-size-number-format"></a>
|
<a name="index-radix-for-section-sizes"></a>
|
<p>Using one of these options, you can control whether the size of each
|
section is given in decimal (<samp>-d</samp>, or <samp>--radix=10</samp>); octal
|
(<samp>-o</samp>, or <samp>--radix=8</samp>); or hexadecimal (<samp>-x</samp>, or
|
<samp>--radix=16</samp>). In <samp>--radix=<var>number</var></samp>, only the three
|
values (8, 10, 16) are supported. The total size is always given in two
|
radices; decimal and hexadecimal for <samp>-d</samp> or <samp>-x</samp> output, or
|
octal and hexadecimal if you’re using <samp>-o</samp>.
|
</p>
|
</dd>
|
<dt><code>--common</code></dt>

<dd><p>Print total size of common symbols in each file. When using Berkeley

|
<p>Specify that the object-code format for <var>objfile</var> is
|
<var>bfdname</var>. This option may not be necessary; <code>size</code> can
|
automatically recognize many formats.
