## Message

```
Sema: restrict what can appear in a naked function

 * Disable runtime calls, since it is not possible to know the proper
   stack adjustment to follow the callee abi.
 * Disable runtime returns, since it is not possible to know where the
   return address is stored in general.
 * Allow implicit returns regardless of the return type, which allows
   naked functions with a non-void return type to be written.

```
