[cfe-dev] Strange return value of Sema::CheckFunctionReturnType

[陳韋任 via cfe-dev]

Hi All,

  While reading Sema::CheckFunctionReturnType in SemaType.cpp [1], I
find something strange.
>From the context, the return value of CheckFunctionReturnType indicate
something is invalid.
If the check fail, CheckFunctionReturnType returns true.

The other two checks in CheckFunctionReturnType return true as I
expected. But the following
check return 0, which should be false.

    if (T->isObjCObjectType()) {
      Diag(Loc, diag::err_object_cannot_be_passed_returned_by_value) << 0 << T;
      return 0;
    }

Is it a bug? Or I am reading the code wrong?

Thanks.
