<br></div><div><div> template<typename T> class B;</div><div> </div>
<div> template <typename T><br></div><div> class A {</div><div> template<typename S> friend class B<S>::ty;</div><div> };</div><div> template <typename T> class B {</div><div> struct ty {};</div>
<div> };</div><div> </div><div> void test() {</div><div> (void)sizeof(A<int>);</div><div> }</div></div><div><br></div><div>you didn't update CheckFriendTypeDecl or any of its callers. CheckFriendTypeDecl does this: <br>
</div><div><br></div> // C++11 [class.friend]p3:<div> // A friend declaration that does not declare a function shall have one</div><div> // of the following forms:</div><div> // friend elaborated-type-specifier ;</div>
<div> // friend simple-type-specifier ;</div><div> // friend typename-specifier ;</div><div> if (getLangOpts().CPlusPlus11 && LocStart != FriendLoc)</div><div> Diag(FriendLoc, diag::err_friend_not_first_in_declaration) << T;</div>
<div><br></div><div>what happens is that LocStart now starts at the "template" keyword while the FriendLoc is the "friend" keyword.</div><div><br></div><div>I'm going to try fixing it tonight, but if I can't then I might have to revert it temporarily and please resubmit when you have this bug fixed.</div>
