25 * This is used by architectures to keep arguments on the stack
26 * untouched by the compiler by keeping them live until the end.
27 * The argument stack may be owned by the assembly-language
28 * caller, not the callee, and gcc doesn't always understand
31 * We have the return value, and a maximum of six arguments.
33 * This should always be followed by a "return ret" for the
34 * protection to work (ie no more work that the compiler might
35 * end up needing stack temporaries for).
