Francois Pichet a9f436b064 Revert 132332 (Microsoft friend as a forward declaration), John McCall pointed out a better/simpler way to do it.

Francois Pichet 3fd47df366 For compatibility with MSVC, a friend declaration also act as a forward declaration if the tag name is not already declared. The tag name is declared in the next outermost non record scope.
Example:

class A {
  friend class B;
  B* b;
};
B* global_b;

Francois Pichet a8032e96b5 MSVC doesn't do any validation regarding exception specification.

Francois Pichet efb1af9ae8 Emulate a MSVC bug where if during an using declaration name lookup, the declaration found is unaccessible (private) and that declaration was bring into scope via another using declaration whose target declaration is accessible (public) then no error is generated.
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.

Francois Pichet c2fac71c75 Revert 131347. It asserts if the specialization in within a class template:
template<class U> 
struct X1 {
  template<class T> void f(T*);
  template<> void f(int*) { } 
};

Won't be so simple. I need to think more about it.

Francois Pichet 6744e14d9c In Microsoft mode, allow template function explicit specialization at class scope.
Necessary to parse MFC and MSVC standard lib code.

Example:
struct X {
  template<class T> void f(T) { }
  template<> void f(int) { } 
}

Francois Pichet b796b632a8 In Microsoft mode, allow conversion from pointer to integral type no matter what size the integral type is. Necessary to parse MFC code.
Example:
void f(char *ptr) {
  char var = (char)ptr;
}

Francois Pichet e900b10a29 Downgrade error "static declaration of 'foo' follows non-static declaration" to a warning in Microsoft mode.

Francois Pichet 48c946e5ef In Microsoft mode, within class scope, if a CXXScopeSpec's type is equal to the type of one of the base classes then downgrade the missing typename error to a warning. Up to now this is the only case I found where MSVC doesn't require "typename" at class scope. Really strange!
This fixes 1 error when parsing the MSVC 2008 header files.
Example:

template<class T> class A {
public:
  typedef int TYPE;
};
template<class T> class B : public A<T> {
public:
  A<T>::TYPE a; // no typename required because A<T> is a base class.
};

Francois Pichet 53fe2bb29e MSVC accepts that default parameters be redefined for member functions
of template class. The new value is ignored.

This fixes 1 error when parsing MSVC 2010 header files with clang.

Francois Pichet 3096d209bf Accept __declspec(dllimport) for function defined at class scope in Microsoft mode.
This fixes a bunch of errors when compiling MSVC header files with the -DDLL flag.

Francois Pichet 13b4e68642 Downgrade err_mismatched_exception_spec to a ExtWarning in Microsoft mode. MSVC doesn't do any validation on exception specifications.

John McCall 8feeb49662 Semantic checking for exception specifications should be triggered by
whether C++ exceptions are enabled, not exceptions in general.  PR9358.

Douglas Gregor 996a735b88 We need a longer long when testing this pathe Microsoft fixed-underlying-type extension for enumeration types
llvm-svn: 126250
2011-02-22 21:42:31 +00:00
Douglas Gregor a1aec29a2d Enable enumeration types with a fixed underlying type, e.g.,
enum X : long { Value = 0x100000000 };

when in Microsoft-extension mode (-fms-extensions). This (now C++0x)
feature has been supported since Microsoft Visual Studio .NET 2003.

Francois Pichet a310806ae5 Microsoft enum extensions. 2 things will change on -fms-extensions:
1. enum underlying type is int by default.
2. Error "enumerator value is not representable in the underlying type"is a ExtWarning

Assigning an underlying integral type to an enum forward declaration will come in a next patch.
