Richard Smith	8b86f2d401	Implement final resolution of DR1402: implicitly-declared move operators that ... would be deleted are still declared, but are ignored by overload resolution. Also, don't delete such members if a subobject has no corresponding move operation and a non-trivial copy. This causes us to implicitly declare move operations in more cases, but risks move-assigning virtual bases multiple times in some circumstances (a warning for that is to follow). llvm-svn: 193969	2013-11-04 01:48:18 +00:00
Richard Smith	b4d2a15d17	If a defaulted special member is implicitly deleted, check whether it's ... overriding a non-deleted virtual function. The existing check for this doesn't catch this case, because it fires before we mark the method as deleted. llvm-svn: 178563	2013-04-02 19:38:47 +00:00
David Blaikie	7e414261f6	Implement C++ 10.3p16 - overrides involving deleted functions must match. ... Only deleted functions may override deleted functions and non-deleted functions may only override non-deleted functions. llvm-svn: 166082	2012-10-17 00:47:58 +00:00
