+code generator into target-specific machine instructions.  There are several 
+well-known ways to do this in the literature.  LLVM have three types of
+instruction selector.  1. SelectionDAG 2. FastIsel 3. GlobalIsel.
+
+`GlobalIsel <https://llvm.org/docs/GlobalISel/index.html>`_ is intended to 
+be a replacement of SelectionDAG and FastIsel. 
 
 Portions of the DAG instruction selector are generated from the target
 description (``*.td``) files.  Our goal is for the entire instruction selector
