Author: phosek Date: Thu Apr 6 16:06:33 2017 New Revision: 299711 URL: http://llvm.org/viewvc/llvm-project?rev=299711&view=rev Log: [CMake][libcxx] Use check_c_compiler_flag to check for nodefaultlibs
We're using -nodefaultlibs to avoid the dependency on C++ library when using check_cxx_compiler_flag, and as such we cannot use check_cxx_compiler_flag to check the availability of -nodefaultlibs itself.
