<p>Except when the <tt>inbounds</tt> keyword is present, there is no limitation
on indexing beyond the end of the array implied by the static type (though
any loads or stores must of course be within the bounds of the allocated
object!). This means that single-dimension 'variable sized array' addressing
can be implemented in LLVM with a zero length array type. An implementation
of 'pascal style arrays' in LLVM could use the type
"<tt>{ i32, [0 x float]}</tt>", for example.</p>

used as function return types. The specific limit on how large an aggregate
