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.
