| <h2 class="chapter">19 Specifying a Debugging Target</h2> |
| |
| <a name="index-debugging-target"></a> |
| <p>A <em>target</em> is the execution environment occupied by your program. |
| </p> |
| <p>Often, <small>GDB</small> 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 <small>GDB</small> 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 <small>GDB</small> |
| (see <a href="Target-Commands.html#Target-Commands">Commands for Managing Targets</a>). |
| </p> |
| <a name="index-target-architecture"></a> |
| <p>It is possible to build <small>GDB</small> for several different <em>target |
| architectures</em>. When <small>GDB</small> is built like that, you can choose |
| one of the available architectures with the <kbd>set architecture</kbd> |
| command. |
| </p> |
| <dl compact="compact"> |
| <dd><a name="index-set-architecture"></a> |
| <a name="index-show-architecture"></a> |
| </dd> |
| <dt><code>set architecture <var>arch</var></code></dt> |
| <dd><p>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. |
| </p> |
| </dd> |
| <dt><code>show architecture</code></dt> |
| <dd><p>Show the current target architecture. |
| </p> |
| </dd> |
| <dt><code>set processor</code></dt> |
| <dt><code>processor</code></dt> |
| <dd><a name="index-set-processor"></a> |
| <a name="index-show-processor"></a> |
| <p>These are alias commands for, respectively, <code>set architecture</code> |
| and <code>show architecture</code>. |
