I've been investigating the libgcc sources, what do you think of something alike this solution

Today in "gcc/libgcc/Makefile.in" its filtered on which functions that should be compiled with unwind-info:

   # These might cause a divide overflow trap and so are compiled with
   # unwinder info.
   LIB2_DIVMOD_FUNCS = _divdi3 _moddi3 _udivdi3 _umoddi3 _udiv_w_sdiv _udivmoddi4

What if this could be overridden by configuration option?

In addition to that it would be nice if the target configuration can override this also.
