Author: jlebar Date: Wed Mar 23 17:42:27 2016 New Revision: 264205 URL: http://llvm.org/viewvc/llvm-project?rev=264205&view=rev Log: [CUDA] Don't define __NVCC__.
Summary: We decided this makes life too difficult for code authors. For example, people may want to detect NVCC and disable variadic templates, which NVCC does not support, but which we do. Since people are going to have to change compiler flags *anyway* in order to compile with clang, if they really want the old behavior, they can pass -D__NVCC__. Tested with tensorflow and thrust, no apparent problems.
