<h5>Overview:</h5>
<p>As in many languages, the pointer type represents a pointer or reference to
another object, which must live in memory. Pointer types may have an optional
address space attribute defining the target-specific numbered address space
where the pointed-to object resides. The default address space is zero.</p>
<p>The pointer type is used to specify memory locations.
Pointers are commonly used to reference objects in memory.</p>
<p>Pointer types may have an optional address space attribute defining the
numbered address space where the pointed-to object resides. The default
address space is number zero. The semantics of non-zero address
spaces are target-specific.</p>
<p>Note that LLVM does not permit pointers to void (<tt>void*</tt>) nor does it
permit pointers to labels (<tt>label*</tt>). Use <tt>i8*</tt> instead.</p>
