To the best of my information, at the very least
-fno-asynchronous-unwind-tables has no effect on debuggability
if debug info is present.
Thus is it should be set always.
Did you check whether -fno-unwind-tables has any effect at all?
I think this one is potentially not completely safe (we do have
C++ code) and it would be better to not add it unless it really
provides a significant benefit.
