I believe this is by choice because no one has yet written an unwinder for the ARM exception tables for Ada :( .

Ada is supposed to be using the same libgcc unwinder as the rest of the compiler. So this cannot be it, exactly.

I don't follow Ada much, so if it's not the unwinder then the next place to look would be the generator.


Googling around -
http://gcc.gnu.org/ml/gcc-patches/2009-09/msg00471.html appears to suggest that GNAT needs to know more to generate the ARM EH unwind tables for the ZCX approach.


On Aarch64 life should be much simpler given that it uses the standard eh_frame mechanisms.



Perhaps some silly bit of configury is wrong?

If things have changed maybe it is ....
