Author: mgorny Date: Thu Jan 3 08:43:27 2019 New Revision: 350329 URL: http://llvm.org/viewvc/llvm-project?rev=350329&view=rev Log: [clangd] Fix detecting atomics in stand-alone builds
Include CheckAtomic CMake module from LLVM in order to detect support for atomics when building stand-alone. Otherwise, the HAVE_CXX_ATOMICS64_WITHOUT_LIB variable is undefined and clangd wrongly attempts to link -latomic on systems not using the library.
