[Bug ports/2682] On ARM EABI, exit should be marked EXIDX_CANTUNWIND


------- Additional Comments From jsm28 at gcc dot gnu dot org  2006-05-22 11:33 -------
Yes, it's a general C++ requirement from 18.3 [lib.support.start.term] paragraph 5.

If on a given platform you can tell that there isn't unwind information for the
stack frame for exit, then the unwinding will stop there; it's a peculiarity of
ARM unwind information that you can't tell that and need unwind information all
the way up the stack until explicitly marked to stop unwinding.  I don't know
how or whether this (avoiding unwinding through exit) works on IA64 where
everything has unwind information by default.
