<br>
we have currently three Ada related configuration options:<br>
<br>
* CONFIGURE_GNAT_RTEMS<br>
<br>
* CONFIGURE_MAXIMUM_ADA_TASKS<br>
<br>
* CONFIGURE_MAXIMUM_FAKE_ADA_TASKS<br>
<br>
The CONFIGURE_MAXIMUM_FAKE_ADA_TASKS option has no effect. The <br>
CONFIGURE_GNAT_RTEMS is mandatory to use the CONFIGURE_MAXIMUM_ADA_TASKS <br>
option. So, if you just use<br>
<br>
#define CONFIGURE_MAXIMUM_ADA_TASKS 123<br>
<br>
then you get a re-definition warning and hopefully pay attention to it. <br>
This is not very user friendly from point of view.<br>
<br>
The CONFIGURE_MAXIMUM_ADA_TASKS just adds the configured count to <br>
CONFIGURE_MAXIMUM_POSIX_THREADS.<br>
<br>
I would obsolete all three options.<br></blockquote><div><br></div><div>The original purpose of these was to:</div><div><br></div><div>CONFIGURE_GNAT_RTEMS - add in resources required by Ada run-time independent</div><div>of the number of Ada tasks (e.g. POSIX threads)</div><div><br></div><div>CONFIGURE_MAXIMUM_ADA_TASKS - add in POSIX threads, condition variable,</div><div>and mutex required for each Ada task</div><div><br></div><div>CONFIGURE_MAXIMUM_FAKE_ADA_TASKS - add in condition variables and mutex</div><div>required by Ada run-time for a task/thread created outside the Ada run-time which </div><div>invokes Ada code and is thus a user of the run-time.</div><div><br></div><div>Given that you can turn on unlimited threads now and condition variables and mutexes</div><div>are static, I don't think they have a need any longer.
