[cfe-dev] clang -fms-extensions mode, tasks to do.

[Francois Pichet]

For people interesting in improving the -fms-extensions mode of clang,
here is a non complete list of tasks to do.
Those are some of the extensions that must be added to clang in order
to parse the Windows SDK header files bundled with VS 2008.
I plan to address every one of those in roughly that order but if you
want to help that's more than welcome because
the amount of time I can put on clang is (unfortunately) limited.

BTW those are just parsing issues (--fsyntax-only).

MSVC issues:

1. clang must parse this:
   extern "C++" template<class T> f(T a);

2. clang must parse this:
     0x6cb9a43e+(1), <== hexadecimal literal lexing  issue


3. type_info predeclared, IUnknown predeclared
  add "class type_info;struct IUnknown;" in MacroBuilder?

4. __pragma support
	
5. __uuidof opertor

6. flexible array member in union

example:
typedef struct _PROPERTYINSTEX
{
    WORD Length;
     union
    {
        BYTE Byte[];
        WORD Word[];
        DWORD Dword[];
        LARGE_INTEGER LargeInt[];
        SYSTEMTIME SysTime[];
        TYPED_STRING TypedString;
    };
} PROPERTYINSTEX;


7. clang must parse this: (superfluous A::)
     class A {
         int A::f() { return 0; }
      };


8. clang must parse this:
     enum TATA {
          a = (TATA) 3
      };
	
9. MSVC Compiler Intrinsics
    ex: __noop
