-If a `static` function is used as an address-taken function for cross-compartment calls, then the rewriter needs to add `__attribute__((used))` to the function declaration in order for it to link correctly with the generated callgates. Normally the rewriter can achieve this, but if the `static` keyword comes from a macro the rewriter will not be able to insert the attribute. For example:
