* Rename LangOptions::Microsoft to LangOptions::MicrosoftExt to make it clear ↵Francois Pichet2011-09-171-1/+1
| | | | | | | | that this flag must be used only for Microsoft extensions and not emulation; to avoid confusion with the new LangOptions::MicrosoftMode flag. Many of the code now under LangOptions::MicrosoftExt will eventually be moved under the LangOptions::MicrosoftMode flag. llvm-svn: 139987

Example: class A { public: int f(); }; class B : public A { private: using A::f; }; class C : public B { private: using B::f; }; Here, B::f is private so this should fail in Standard C++, but because B::f refers to A::f which is public MSVC accepts it. This fixes 1 error when parsing MFC code with clang. llvm-svn: 131896
* Undo enough of r131143 to make private copy ctor diags say "copy ↵Matt Beaumont-Gay2011-05-191-2/+6

* Re-do R131114 without breaking code.Alexis Hunt2011-05-101-6/+4
| | | | | | | | | I've edited one diagnostic which would print "copy constructor" for copy constructors and "constructor" for any other constructor. If anyone is extremely enamored with this, it can be reinstated with a simple boolean flag rather than calling getSpecialMember, which is inappropriate. llvm-svn: 131143

* When parsing an out-of-line member function declaration, we must delayJohn McCall2011-02-141-7/+13
| | | | | | | | | | | | | | | | | | | | | | access-control diagnostics which arise from the portion of the declarator following the scope specifier, just in case access is granted by friending the individual method. This can also happen with in-line member function declarations of class templates due to templated-scope friend declarations. We were really playing fast-and-loose before with this sort of thing, and it turned out to work because *most* friend functions are in file scope. Making us delay regardless of context exposed several bugs with how we were manipulating delay. I ended up needing a concept of a context that's independent of the declarations in which it appears, and then I actually had to make some things save contexts correctly, but delay should be much cleaner now. I also encapsulated all the delayed-diagnostics machinery in a single subobject of Sema; this is a pattern we might want to consider rolling out to other components of Sema. llvm-svn: 125485

* White-listing templated-scope friend decls is a good idea, but doing itJohn McCall2010-10-161-2/+3
| | | | | | | | by marking the decl invalid isn't. Make some steps towards supporting these and then hastily shut them down at the last second by marking them as unsupported. llvm-svn: 116661
* Handle dependent friends more explicitly and deal with the possibilityJohn McCall2010-10-121-0/+4
| | | | | | | | of templated-scope friends by marking them invalid and white-listing all accesses until such time as we implement them. Fixes a crash, this time without a broken test case. llvm-svn: 116364
* Add a quick-and-dirty hack to give a better diagnostic for [class.protected]John McCall2010-09-031-0/+55
| | | | | | | | | | restrictions. The note's not really on the right place given its wording, but putting a second note on the call site (or muddying the wording) doesn't appeal. There are corner cases where this can be wrong, but I'm not concerned. llvm-svn: 112950

* Propagate whether an id-expression is the immediate argument ofJohn McCall2010-08-271-1/+1
| | | | | | | | | | | | | | | | | | | an '&' expression from the second caller of ActOnIdExpression. Teach template argument deduction that an overloaded id-expression doesn't give a valid type for deduction purposes to a non-static member function unless the expression has the correct syntactic form. Teach ActOnIdExpression that it shouldn't try to create implicit member expressions for '&function', because this isn't a permitted form of use for member functions. Teach CheckAddressOfOperand to diagnose these more carefully. Some of these cases aren't reachable right now because earlier diagnostics interrupt them. llvm-svn: 112258

* Pull DelayedDiagnostic and AccessedEntity out into their own header.John McCall2010-08-251-4/+6
| | | | | | | | This works courtesy of the new SmallVector<..., 0> specialization that doesn't require a complete type. Note that you'll need to pull at least SmallVector.h from LLVM to compile successfully. llvm-svn: 112114

* Partial fix for PR7267 based on comments by John McCall on an earlier patch.Chandler Carruth2010-06-281-0/+15
| | | | | | | | | | | | | | | | | | This is more targeted, as it simply provides toggle actions for the parser to turn access checking on and off. We then use these to suppress access checking only while we parse the template-id (included scope specifier) of an explicit instantiation and explicit specialization of a class template. The specialization behavior is an extension, as it seems likely a defect that the standard did not exempt them as it does explicit instantiations. This allows the very common practice of specializing trait classes to work for private, internal types. This doesn't address instantiating or specializing function templates, although those apparently already partially work. The naming and style for the Action layer isn't my favorite, comments and suggestions would be appreciated there. llvm-svn: 106993
