Support for emitting libcalls for __atomic_fetch_nand and __atomic_{add,sub,and,or,xor,nand}_fetch was missing; add it, and some test cases. Differential Revision: http://reviews.llvm.org/D10847 This fixes "cannot compile this atomic library call yet" errors when compiling code which calls the above builtins, on arm < v6. END
