Saleem Abdulrasool	2d5e95c00d	cmake: include what you use ... Add a missing include. This is important in the case HandleLLVMOptions is included prior to the missing CheckCXXSourceCompiles or CheckCXXCompilerFlag which includes CheckCXXSourceCompiles. llvm-svn: 262949	2016-03-08 18:56:00 +00:00
Reid Kleckner	9fac19f02e	[cmake] Check the compiler version first ... Otherwise users get messages from CheckAtomic about missing libatomic instead of a sensible message that says "use GCC 4.7 or newer". I structured the change along the lines of HandleLLVMStdlib.cmake, so that the standalone build of Clang still gets the compiler version check.
