[LLVMdev] Is the online demo using outdated binaries?

[Óscar Fuentes]

Throwing this C++ code at the online demo:

struct S {
  double d;
  unsigned u;
};

S foo() {
  return S();
}

produces this LLVM C++ API code:

(...)
  PAListPtr func__Z3foov_PAL = 0;
  {
    SmallVector<ParamAttrsWithIndex, 4> Attrs;
    ParamAttrsWithIndex PAWI;
    PAWI.index = 0; PAWI.attrs = 0  | ParamAttr::NoUnwind;
    Attrs.push_back(PAWI);
    PAWI.index = 1; PAWI.attrs = 0  | ParamAttr::StructRet | ParamAttr::NoAlias;
    Attrs.push_back(PAWI);
    func__Z3foov_PAL = PAListPtr::get(Attrs.begin(), Attrs.end());
    
  }
  func__Z3foov->setParamAttrs(func__Z3foov_PAL);
(...)

Please note that it uses index 1 for the return attributes, which is
inconsistent with what ReleaseNotes.html TOT says:

...
* Return value attributes are stored at index 0. Function attributes are
stored at index ~0U. Parameter attributes are stored at index that
matches parameter number.
...

Apart from this, the online demo page mentions llvm2cpp, which does not
exists since 2.3:
