Hello Everyone,
This patch is for the Cilkplus branch affecting both C and C++ compilers.
The dwarf output function was looking for debugging information for an
internally generated spawn helper which is not there. So this patch will make
sure that those functions are excluded.
Thanks,
Balaji V. Iyer.
