/////////////////////////////////////
//
// Interface to create literal classes.
//
//  void ISA_Lits_Begin(void)
//      Initialize to generate literal class information for an architecture.
//      The information will be written to the files targ_isa_lits.[ch].  
//
//  TYPE LIT_RANGE
//      An abstract type that represents a literal range.
//      No client visible fields.
//
//  const LIT_RANGE LIT_RANGE_END
//	A special LIT_RANGE value that is used to mark the end of a
//	list of LIT_RANGE parameters.
//
//  LIT_RANGE ISA_Create_Lit_Range(const char *name, 
//				   long long min, long long max)
//	Create a literal range named <name> (used for debugging/informational
//	purposes only) with minimum value <min> and maximum value <max>.
//
//  LIT_RANGE SignedBitRange(unsigned int bit_size)
//  LIT_RANGE UnsignedBitRange(unsigned int bit_size)
//	Create a signed/unsigned literal range for a bit-field of size
//	<bit_size>.
//
//  TYPE (enum) LIT_CLASS_TYPE
//	An enumeration of the types of literals: eg, UNSIGNED or SIGNED.
//
//  void ISA_Create_Lit_Class (const char *name, LIT_CLASS_TYPE type, ...)
//	Create a LIT CLASS with the <name> and type <type>. The variable
//	argument list contains a sequence of LIT_RANGE parameters to
//	identify one or more disjoint ranges that are legal for the
//	literal class. The list is ended with a parameter of LIT_RANGE_END.
//
//  void ISA_Lits_End(void)
//      Complete processing of literals.
