+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 the first four components are the same as the *Target Triple*
+(see :ref:`amdgpu-target-triples`), the next component is the same as
+the *Processor* (see :ref:`amdgpu-processors`) and the last component
+is a comma separated list of the enabled *Target Features* that apply
+to *Processor* in the same order as listed in the table
+:ref:`amdgpu-target-feature-table` (see
+:ref:`amdgpu-target-features`). 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"``
