<h5 class="subsubsection">15.4.10.9 Tasking Support when using the Ravenscar Profile</h5>

<p><a name="index-Ravenscar-Profile-1080"></a>
The <dfn>Ravenscar Profile</dfn> is a subset of the Ada tasking features,
specifically designed for systems with safety-critical real-time
requirements.

     
<a name="index-set-ravenscar-task_002dswitching-on-1081"></a>
<a name="index-task-switching-with-program-using-Ravenscar-Profile-1082"></a>
<dl><dt><code>set ravenscar task-switching on</code><dd>Allows task switching when debugging a program that uses the Ravenscar
Profile.  This is the default.

     <p><a name="index-set-ravenscar-task_002dswitching-off-1083"></a><br><dt><code>set ravenscar task-switching off</code><dd>Turn off task switching when debugging a program that uses the Ravenscar
Profile.  This is mostly intended to disable the code that adds support
for the Ravenscar Profile, in case a bug in either <span class="sc">gdb</span> or in
the Ravenscar runtime is preventing <span class="sc">gdb</span> from working properly. 
To be effective, this command should be run before the program is started.

     <p><a name="index-show-ravenscar-task_002dswitching-1084"></a><br><dt><code>show ravenscar task-switching</code><dd>Show whether it is possible to switch from task to task in a program
using the Ravenscar Profile.
