-- | Hard wired things related to registers.
-- This is module is preventing the native code generator being able to
-- emit code for non-host architectures.
--
-- TODO: Do a better job of the overloading, and eliminate this module.
-- We'd probably do better with a Register type class, and hook this to
-- Instruction somehow.
--
-- TODO: We should also make arch specific versions of RegAlloc.Graph.TrivColorable
