Rafael Espindola [Tue, 3 Sep 2013 21:05:13 +0000 (21:05 +0000)]
Don't emit an available_externally vtable pointing to linkonce_odr funcs.

This fixes pr13124.

From the discussion at
http://lists.cs.uiuc.edu/pipermail/cfe-dev/2012-June/022606.html
we know that we cannot make funcions in a weak_odr vtable also weak_odr. They
should remain linkonce_odr.

The side effect is that we cannot emit a available_externally vtable unless we
also emit a copy of the function. This also has an issue: If codegen is going
to output a function, sema has to mark it used. Given llvm.org/pr9114, it looks
like sema cannot be more aggressive at marking functions used because
of vtables.

This leaves us with a few unpleasant options:

* Marking functions in vtables used if possible. This sounds a bit sloppy, so
  we should avoid it.
* Producing available_externally vtables only when all the functions in it are
  already used or weak_odr. This would cover cases like

--------------------
struct foo {
  virtual ~foo();
};
struct bar : public foo {
  virtual void zed();
};
void f() {
  foo *x(new bar);
  delete x;
}
void g(bar *x) {
  x->~bar(); // force the destructor to be used
}
--------------------------

and

----------------------------------
template<typename T>
struct bar {
  virtual ~bar();
};
template<typename T>
bar<T>::~bar() {
}

// make the destructor weak_odr instead of linkonce_odr
extern template class bar<int>;

void f() {
  bar<int> *x(new bar<int>);
  delete x;
}
----------------------------

These look like corner cases, so it is unclear if it is worth it.

* And finally: Just nuke this optimization. That is what this patch implements.

Mark that qualifiers can prefix the auto type. This seems to just have
been an oversight, as it definitely works. Every test which changed had
the const written on the LHS of the auto already.

Yes, many people feel that 'const' and other qualifiers belong on the

*overwhelming* places the qualifiers on the LHS when it can and on the

inlined, since this feature is still broken. Still, this is sufficient to

Sema: avoid reuse of Exprs when synthesizing operator=

Summary:
Previously, Sema was reusing parts of the AST when synthesizing an assignment
operator, turning it into a AS-dag. This caused problems for the static
analyzer, which assumed an expression appears in the tree only once.

Here I make sure to always create a fresh Expr, when inserting something into
the AST, fixing PR16745 in the process.

function, rather than having a separate pass over dynamic classes at the end of
