Cilk with -lcilkrts (was: Re: [wwwdocs] RFC - mention Cilk Plus in the GCC 4.9 release notes)

It would be also good if the documentation mentioned that you have to

Wouldn't it make more sense to automatically add the option? For

I don't understand spec well enough to say if your patch is enough. (but have to document then that -fcilkplus is also needed on the link command) -Andi
