            Bug ID: 45919
           Summary: Different AST exposed for functions tagged with
                    __stdcall.
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: libclang
          Assignee: unassignedclangbugs at nondot.org
          Reporter: emilio at crisal.io
                CC: klimek at google.com, llvm-bugs at lists.llvm.org,

                    unassignedclangbugs at nondot.org
        Depends on: 39705

See https://github.com/rust-lang/rust-bindgen/issues/1778.

For the following function, there's a bunch of CXCursor_ParamDecl:

  typedef
    void
    EVT_VIGEM_X360_NOTIFICATION(
        void* Client,
        void* Target,
        unsigned char LargeMotor,
        unsigned char SmallMotor,
        unsigned char LedNumber,
        void* UserData
    );

  typedef EVT_VIGEM_X360_NOTIFICATION *PFN_VIGEM_X360_NOTIFICATION;

Now add __stdcall:

  typedef
    void __stdcall
    EVT_VIGEM_X360_NOTIFICATION(
        void* Client,
        void* Target,
        unsigned char LargeMotor,
        unsigned char SmallMotor,
        unsigned char LedNumber,
        void* UserData
    );

  typedef EVT_VIGEM_X360_NOTIFICATION *PFN_VIGEM_X360_NOTIFICATION;

And they go missing.
