/*
* HISTORY
* $Log: machine.h,v $
* 2 July 1992 Mac Gillon at NeXT
* Changed HPPA subtypes to follow our practice.
*
* 11 September 1992 David E. Bohman at NeXT
* Added CPU_SUBTYPE_486SX to the i386 family.
*
* 16 July 1992 David E. Bohman at NeXT
* Added CPU_SUBTYPE_586 to the i386 family.
*
* 17-Dec-91 Peter King (king) at NeXT
* Added support for the XXX_ALL subtypes. These are used to
* tag object files that can run on any implementation of a
* particular family.
*
* 1-Mar-90 John Seamons (jks) at NeXT
* Redefined cpu_type and cpu_subtype definitions to indicate processor
* architecture instead of product types for the MC680x0.
*
* Revision 2.15 89/10/11 14:39:56 dlb
* Removed should_exit - replaced by action thread.
* [89/01/25 dlb]
*
* Revision 2.14 89/07/14 17:21:39 rvb
* Added CPU types and subtypes for MC68030, MC68040, MC88000,
* HPPA, ARM and Sun4-SPARC.
* [89/07/13 mrt]
*
* Revision 2.12 89/05/30 10:38:58 rvb
* Add R2000 machine types.
* [89/05/30 08:28:53 rvb]
*
* Revision 2.11 89/04/18 16:43:32 mwyoung
* Use <machine/vm_types.h> rather than <vm/vm_param.h> to get
* VM types. Remove old history... none of it was insightful.
*
* The variable declarations should be moved elsewhere.
* [89/01/24 mwyoung]
