-code generator currently targets a generic P6-like processor. As such, it
-produces a few P6-and-above instructions (like conditional moves), but it does
-not make use of newer features like MMX or SSE. In the future, the X86 backend
-will have sub-target support added for specific processor families and
-implementations.</p>
+code generator is capable of targeting a variety of x86-32 and x86-64
+processors, and includes support for ISA extensions such as MMX and SSE.
