================
Comment at: llvm/docs/LangRef.rst:9694-9695
 the position from which to extract the element. The index may be a
-variable of any integer type.
+variable of any integer type, and will be zero extended or truncated 
+depending on the target.
 
----------------
>From a semantics point of view, I think all we need to say is that the value is "treated as unsigned" or words to that effect. I don't think we should mention extending here (and definitely not truncating which sounds like it could change the value!).
