-'``llvm.noalias``' Intrinsic
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Syntax:
-"""""""
-
-::
-
-      declare <type>* @llvm.noalias.p<address space><type>(<type>* %ptr, metadata %scopes)
-
-Overview:
-"""""""""
-
-``llvm.noalias`` allows the optimizer to assume that memory accesses using
-pointers :ref:`based <pointeraliasing>` on the return value don't alias with
-memory accesses, tagged with the provided ``noalias`` scope, using pointers not
-derived from the return value.
-
-Arguments:
-""""""""""
-
-The first argument is the pointer on which the aliasing assumption is being
-placed. This pointer value is returned, but parts of the optimizer ignore this
-fact so that data dependencies on the return value will be maintained. The
-aliasing assumptions apply only to uses of pointers
-:ref:`based <pointeraliasing>` on the return value.
-
-The second argument is metadata that is a list of ``noalias`` metadata
-references. The format is identical to that required for ``noalias`` metadata.
-This list should have only one element.
-
-Semantics:
-""""""""""
-
-``llvm.noalias`` allows the optimizer to assume that memory accesses using
-pointers :ref:`based <pointeraliasing>` on from the return value don't alias
-with memory accesses, tagged with compatible ``noalias`` scopes (i.e. the scope
-provided to the intrinsic must be one of the scopes with which the access is
-tagged), using pointers not based on the return value.  See the description of
-``alias.scope`` and ``noalias`` metadata for more information. The aliasing
-assumptions apply only to uses of pointers based on the return value, and
-accesses using those pointers must themselves be tagged with ``noalias``
-metadata with compatible scopes.
-
-Unlike ``alias.scope`` metadata, which applies to only the access to which it
-is attached, the ``llvm.noalias`` intrinsic applies to all pointers based on
-from the return value. Placing an ``llvm.noalias`` intrinsic outside of a loop
-provides a mechanism for communicating that certain memory accesses don't alias
-with uses of a pointer in any loop iteration. This works only if the
-``llvm.noalias`` intrinsic itself dominates the loop body.
-
-Note that the use of ``alias.scope`` metadata does not block potential
-optimizations, as ``llvm.noalias`` might, and so use of  ``alias.scope``
-metadata when possible is recommended. Nevertheless, no code is generated for
-this intrinsic.
