[cfe-dev] clang + cuda version issue

[Burlen Loring via cfe-dev]

hmm, perhaps this is not the list to ask such a question. Does any one 
have insight to where a new user can get information about the plan for 
supporting more recent cuda versions? is there work in progress? is it 
documented somewhere?

Thanks
