// isa_hazards_gen.h
/////////////////////////////////////
//
//  Interface for describing instructions that have ISA hazards, and what
//  the hazard is.
//
//  void ISA_Hazards_Begin( const char* archname )
//      Initialize to generate Instruction Set Architecture hazard information
//      for the architecture with the given <archname>.  The information will
//      be written to the files <archname>_hazards.[ch].  
//
//  TYPE ISA_HAZARD
//      An abstract type that represents a type of ISA hazard.
//      No client visible fields.
//
//  ISA_HAZARD Hazard_Create( const char *name )
//      Used to create a new ISA_HAZARD. <name> is used to construct
//      an enumeration constant for this hazard in the generated output
//	of the form: ISA_HAZARD_<name>
//
//  void Hazard_Group( TOP topcode, ... )
//      Lists a group of instructions (by TOP), with a common hazard 
//	specification, terminating in TOP_UNDEFINED. Subsequent
//	statements specify the details of the hazard. The specification
//	is terminated by another Hazard_Group, or ISA_Hazards_End.
//
//  void Hazard_Type( ISA_HAZARD isa_hazard )
//	Indicates the type of the hazard.
//
//  void Hazard_Data( int data )
//	One word of hazard-specific data, e.g. an operand number.
//
//  void Hazard_Post_Ops( int ops )
//	The number of OPs which must follow an OP in the hazard group
//
//  void Hazard_Pre_Ops( int ops )
//	The number of OPs which must precede an OP in the hazard group
//
//  void Hazard_ISA( ISA_SUBSET isa_subset )
//	Not all ISAs have the same hazards. Hazard_ISA specifies that
//	'isa_subset' has the current hazard. Hazard_ISA may be called
//	multiple times per hazard group.
//
//  void ISA_Hazards_End(void)
//      Complete processing.
