When a built-in function is supported on your architecture, it will be compiled directly, and will not result in an external reference. Some built-in functions are always supported. Some are only supported directly if the architecture supports them. Some have a fallback in libgcc.a, which means that the C library does not need to provide a version. If you have a question about a specific built-in function, please ask that question. Ian
