[LLVMdev] Can insertvalue ignore its last operand?

[Jianzhou Zhao]

Hi,

Some of my code is compiled to

  %insert2 = insertvalue { float, float } %insert, float %33

When the index value (the last operand) is omitted, does it mean it
uses some default value, say 0?
The manual does not allow this syntax though.
  http://llvm.org/docs/LangRef.html#i_insertvalue

Thanks.
