Some vendors provide language extensions for specifying whether or not a function throws. For instance, Microsoft Visual Studio provides __declspec(nothrow)), and Clang supports __attribute__((nothrow)). Currently, the vendors do not document the behavior of specifying a nonthrowing function using these extensions. Throwing from a function declared with one of these language extensions is presumed to be undefined behavior.
