--- Comment #1 from Reid Kleckner <rnk at google.com> ---
Looks like the frontend forgot to add uwtable, which clang adds.

See the comment above AttrKind about this:
http://llvm.org/docs/doxygen/html/classllvm_1_1Attribute.html#aab7ee4b8fd1d3e7e4cea87868855e60e

And the implementation of Function::needsUnwindTableEntry:
  /// @brief True if this function needs an unwind table.
  bool needsUnwindTableEntry() const {
    return hasUWTable() || !doesNotThrow();
  }
