+Code Object Target Identification
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The AMDHSA OS uses the following syntax to specify the code object
+target as a single string:
+
+ ``<Architecture>-<Vendor>-<OS>-<Environment>-<Processor><Target Features>``
+
+Where:
+
+ - ``<Architecture>``, ``<Vendor>``, ``<OS>`` and ``<Environment>``
+ are the same as the *Target Triple* (see
+ :ref:`amdgpu-target-triples`).
+
+ - ``<Processor>`` is the same as the *Processor* (see
+ :ref:`amdgpu-processors`).
+
+ - ``<Target Features>`` is a list of the enabled *Target Features*
+ (see :ref:`amdgpu-target-features`), each prefixed by a plus, that
+ apply to *Processor*. The list must be in the same order as listed
+ in the table :ref:`amdgpu-target-feature-table`. Note that *Target
+ Features* must be included in the list if they are enabled even if
+ that is the default for *Processor*.
+
+For example:
+
+ ``"amdgcn-amd-amdhsa--gfx902+xnack"``
