[cfe-commits] [Patch] Add warning for semi-colon after class function definition

[Richard Trieu]

This patch adds a warning to catch semi-colons after function definitions.
 The motivation of removing extraneous semi-colons is to make it easier to
see which scopes are being ended by a brace.  Function scopes will end with
a plain brace.  Class scopes will end with brace and semi-colon.

class C {
  void F() {};
};

extra-semi.cc:2:14: warning: extra ';' after function definition
[-Wextra-semi]
  void F() {};
