If #pragma lint bit 7 (a value of 128) is set, ORCA/C detects cases where it appears that a function declared as _Noreturn may return.

If #pragma lint bit 7 (a value of 128) is set, ORCA/C detects cases where it appears that a function declared as _Noreturn may return. This detects return statements in _Noreturn functions. It also detects some (but not all) cases where a _Noreturn function could return by executing to the end of the function. (This may also report some cases where the code at the end of a _Noreturn function is not actually reachable. The error message is "lint: function declared _Noreturn can return or has unreachable code.")
