I got it working. The Set function was always overwriting the address of the

It turns out that I was building rtems without the --enable-ada option. The
option is not mentioned in configure --help and gnat still builds fine.
Would it be possible to not have the symbol rtems_task_self if the --enable-ada
switch is off? Then linking gnat should fail with an undefined reference.
I don't know too much of the rtems internals, but maybe it is as easy as adding
ifdefs around the SCORE_EXTERN void *rtems_ada_self in score/threadimpl.h?
Since you work on this area, this task variable should go way, since its
broken on SMP systems. I would replace it
o with functions, e.g. rtems_ada_get_self() and
rtems_ada_set_self(), or
o POSIX keys, or
o thread-local storage.
POSIX keys and thread-local storage would make the --enable-ada option
superfluous. Thread-local storage is more efficient. It is well
supported on ARM, PowerPC and SPARC on RTEMS.
@Joel: What shall I do about the changes I made to gcc/ada/s-osinte-rtems.ads
and newlib/libc/sys/rtems/sys/cpuset.h ? Just send the patches to you or should
I push them to the respective lists with you CC?
Please send them as patches to the corresponding lists and CC
de...@rtems.org.
