| </pre></div> |
| |
| |
| <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 |
| .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 |
| </pre></div> |
| |
| </dd> |
| <dt><code>--help</code></dt> |
| <dd><p>Show a summary of acceptable arguments and options. |
| </p> |
| </dd> |
| <dt><code>-d</code></dt> |
| <dt><code>-o</code></dt> |
| <dt><code>-x</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 |
| format these are included in the bss size. |
| </p> |
| </dd> |
| <dt><code>-t</code></dt> |
| <dt><code>--totals</code></dt> |
| <dd><p>Show totals of all objects listed (Berkeley format listing mode only). |
| </p> |
| </dd> |
| <dt><code>--target=<var>bfdname</var></code></dt> |
| <dd><a name="index-object-code-format-2"></a> |
| <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. |
| See <a href="Target-Selection.html#Target-Selection">Target Selection</a>, for more information. |
