-+If control flow reaches the point of the @code{__builtin_unreachable},
-+the program is undefined.  It is useful in situations where the
-+compiler cannot deduce the unreachability of the code.
-+
-+One such case is immediately following an @code{asm} statement that
-+will either never terminate, or one that transfers control elsewhere
-+and never returns.  In this example, without the
-+@code{__builtin_unreachable}, GCC would issue a warning that control
-+reaches the end of a non-void function.  It would also generate code
-+to return after the @code{asm}.

-+
-+Because the @code{asm} statement unconditionally transfers control out
-+of the function, control will never reach the end of the function
-+body.  The @code{__builtin_unreachable} is in fact unreachable and
-+communicates this fact to the compiler.
-+
-+Another use for @code{__builtin_unreachable} is following a call a
-+function that never returns but that is not declared
-+@code{__attribute__((noreturn))}, as in this example:
-+
-+@smallexample
-+void function_that_never_returns (void);

-+int g (int c)
