+Overview:
+"""""""""
+
+The '``llvm.structured.gep``' intrinsic (structured **G**\ et\ **E**\ lement\
**P**\ tr) computes a new pointer address
+resulting of a logical indexing into the ``<source>`` pointer. The returned
+address depends on the indices and may depend on the layout of %basetype at
+runtime.
+
+Arguments:
+""""""""""
+
+``<ty> basetype``:
+The actual value passed is ignored, and should be ``poison``.
+
+``ptr <source>``:
+A pointer to a memory location assumed to hold a completely laid out value
+with the same type as ``basetype``. The physical layout of ``basetype`` is
+target dependent, and is not always known at compile time.
+The assumption this instruction makes on the memory location is only relevant
+to this particular call. A frontend could possibly emit multiple structured
+GEP with the same source pointer but a different ``basetype``.
+
+The ``source`` argument must be annotated with an :ref:`elementtype
+<attr_elementtype>` attribute at the call-site. This attribute specifies the
+type of the element pointed by the pointer source. This type will be
+used along with the provided indices and source operands to compute a new
