| <h2 class="chapter">19 Specifying a Debugging Target</h2> |
| |
| <p><a name="index-debugging-target-1030"></a>A <dfn>target</dfn> is the execution environment occupied by your program. |
| |
| <p>Often, <span class="sc">gdb</span> runs in the same host environment as your program; |
| in that case, the debugging target is specified as a side effect when |
| you use the <code>file</code> or <code>core</code> commands. When you need more |
| flexibility—for example, running <span class="sc">gdb</span> on a physically separate |
| host, or controlling a standalone system over a serial port or a |
| realtime system over a TCP/IP connection—you can use the <code>target</code> |
| command to specify one of the target types configured for <span class="sc">gdb</span> |
| (see <a href="Target-Commands.html#Target-Commands">Commands for Managing Targets</a>). |
| |
| <p><a name="index-target-architecture-1031"></a>It is possible to build <span class="sc">gdb</span> for several different <dfn>target |
| architectures</dfn>. When <span class="sc">gdb</span> is built like that, you can choose |
| one of the available architectures with the <kbd>set architecture</kbd> |
| command. |
| |
| |
| <a name="index-set-architecture-1032"></a> |
| <a name="index-show-architecture-1033"></a> |
| <dl><dt><code>set architecture </code><var>arch</var><dd>This command sets the current target architecture to <var>arch</var>. The |
| value of <var>arch</var> can be <code>"auto"</code>, in addition to one of the |
| supported architectures. |
| |
| <br><dt><code>show architecture</code><dd>Show the current target architecture. |
| |
| <br><dt><code>set processor</code><dt><code>processor</code><dd><a name="index-set-processor-1034"></a><a name="index-show-processor-1035"></a>These are alias commands for, respectively, <code>set architecture</code> |
| and <code>show architecture</code>. |
