 // Use AbstractRegister as shortcut

 typedef AbstractRegisterImpl* AbstractRegister;
 // The super class for platform specific registers. Instead of using value objects,
 // registers are implemented as pointers. Subclassing is used so all registers can
 // use the debugging suport below. No virtual functions are used for efficiency.
 // They are canonicalized; i.e., registers are equal if their pointers are equal,
 // and vice versa. A concrete implementation may just map the register onto 'this'.

 // Macros for use in defining Register instances.  We'd like to be
 // able to simply define const instances of the RegisterImpl* for each
 // of the registers needed on a system in a header file.  However many
 // compilers don't handle this very well and end up producing a
 // private definition in every file which includes the header file.
 // Along with the static constructors necessary for initialization it
 // can consume a significant amount of space in the result library.
 //
 // The following macros allow us to declare the instance in a .hpp and
 // produce an enumeration value which has the same number.  Then in a
 // .cpp the the register instance can be defined using the enumeration
 // value.  This avoids the use of static constructors and multiple
 // definitions per .cpp.  In addition #defines for the register can be
 // produced so that the constant registers can be inlined.  These
 // macros should not be used inside other macros, because you may get
 // multiple evaluations of the macros which can give bad results.
 //
 // Here are some example uses and expansions.  Note that the macro
 // invocation is terminated with a ;.
