 *	"DHRYSTONE" Benchmark Program

 *	Date:		PROGRAM updated 01/06/86, RESULTS updated 03/31/86
 *
 *	Author:		Reinhold P. Weicker,  CACM Vol 27, No 10, 10/84 pg. 1013
 *			Translated from ADA by Rick Richardson
 *			Every method to preserve ADA-likeness has been used,
 *			at the expense of C-ness.
 *
 *	Compile:	cc -O dry.c -o drynr			: No registers
 *			cc -O -DREG=register dry.c -o dryr	: Registers
 *
 *	Defines:	Defines are provided for old C compiler's
 *			which don't have enums, and can't assign structures.
 *			The time(2) function is library dependant; Most
 *			return the time in seconds, but beware of some, like
 *			Aztec C, which return other units.
 *			The LOOPS define is initially set for 50000 loops.
 *			If you have a machine with large integers and is
 *			very fast, please change this number to 500000 to
 *			get better accuracy.  Please select the way to
 *			measure the execution time using the TIME define.
 *			For single user machines, time(2) is adequate. For
 *			multi-user machines where you cannot get single-user
 *			access, use the times(2) function.  If you have
 *			neither, use a stopwatch in the dead of night.
 *			Use a "printf" at the point marked "start timer"
 *			to begin your timings. DO NOT use the UNIX "time(1)"
 *			command, as this will measure the total time to
 *			run this program, which will (erroneously) include
 *			the time to malloc(3) storage and to compute the
 *			time it takes to do nothing.
 *
 *	Run:		drynr; dryr
 *
 *	Results:	If you get any new machine/OS results, please send to:
 *
 *				ihnp4!castor!pcrat!rick
 *
 *			and thanks to all that do.  Space prevents listing
 *			the names of those who have provided some of these
 *			results.  I'll be forwarding these results to
 *			Rheinhold Weicker.
 *
 *	Note:		I order the list in increasing performance of the
 *			"with registers" benchmark.  If the compiler doesn't
 *			provide register variables, then the benchmark
 *			is the same for both REG and NOREG.
 *
 *	PLEASE:		Send complete information about the machine type,
 *			clock speed, OS and C manufacturer/version.  If
 *			the machine is modified, tell me what was done.
 *			On UNIX, execute uname -a and cc -V to get this info.
 *
 *	80x8x NOTE:	80x8x benchers: please try to do all memory models
 *			for a particular compiler.
 *
 *	APOLOGY (1/30/86):
 *		Well, I goofed things up!  As pointed out by Haakon Bugge,
 *		the line of code marked "GOOF" below was missing from the
 *		Dhrystone distribution for the last several months.  It
 *		*WAS* in a backup copy I made last winter, so no doubt it
 *		was victimized by sleepy fingers operating vi!
 *
 *		The effect of the line missing is that the reported benchmarks
 *		are 15% too fast (at least on a 80286).  Now, this creates
 *		a dilema - do I throw out ALL the data so far collected
 *		and use only results from this (corrected) version, or
 *		do I just keep collecting data for the old version?
 *
 *		Since the data collected so far *is* valid as long as it
 *		is compared with like data, I have decided to keep
 *		TWO lists- one for the old benchmark, and one for the
 *		new.  This also gives me an opportunity to correct one
 *		other error I made in the instructions for this benchmark.
 *		My experience with C compilers has been mostly with
 *		UNIX 'pcc' derived compilers, where the 'optimizer' simply
 *		fixes sloppy code generation (peephole optimization).
 *		But today, there exist C compiler optimizers that will actually
 *		perform optimization in the Computer Science sense of the word,
 *		by removing, for example, assignments to a variable whose
 *		value is never used.  Dhrystone, unfortunately, provides
 *		lots of opportunities for this sort of optimization.
 *
 *		I request that benchmarkers re-run this new, corrected
 *		version of Dhrystone, turning off or bypassing optimizers
 *		which perform more than peephole optimization.  Please
 *		indicate the version of Dhrystone used when reporting the
 *		results to me.

 * NOTE

 *   +   This Macintosh was upgraded from 128K to 512K in such a way that
 *       the new 384K of memory is not slowed down by video generator accesses.
 *   %   Single processor; MC == MASSCOMP
 *   NM  A version 7 C compiler written at New Mexico Tech.
 *   @   vanilla Lattice compiler used with MicroPro standard library
 *   S   Shorts used instead of ints
 *   T	 with Chris Torek's patches (whatever they are).
 *   ~   For WICAT Systems: MB=MultiBus, PB=Proprietary Bus

 *   FH  FHC == Frank Hogg Labs (Hazelwood Uniquad 2 in an FHL box).
 *   FX  The Alliant FX/8 is a system consisting of 1-8 CEs (computation

 *   RT  This is one of the RT's that CMU has been using for awhile.  I'm
 *	 not sure that this is identical to the machine that IBM is selling
 *	 to the public.
 *   i1  Normally, the 386/20 starter kit has a 16k direct mapped cache
 *	 which inserts 2 or 3 wait states on a write thru.  These results
 *	 were obtained by disabling the write-thru, or essentially turning
 *	 the cache into 0 wait state memory.
 *   Nnn This machine has multiple processors, allowing "nn" copies of the
 *	 benchmark to run in the same time as 1 copy.
 *   &nn This machine has "nn" processors, and the benchmark results were
 *	 obtained by having all "nn" processors working on 1 copy of dhrystone.
 *	 (Note, this is different than Nnn. Salesmen like this measure).
 *   ?   I don't trust results marked with '?'.  These were sent to me with
 *       either incomplete info, or with times that just don't make sense.
 *	 ?? means I think the performance is too poor, ?! means too good.

 *	The following program contains statements of a high-level programming
 *	language (C) in a distribution considered representative:
 *
 *	assignments			53%
 *	control statements		32%
 *	procedure, function calls	15%
 *
 *	100 statements are dynamically executed.  The program is balanced with
 *	respect to the three aspects:
 *		- statement type
 *		- operand type (for simple data types)
 *		- operand access
 *			operand global, local, parameter, or constant.
 *
 *	The combination of these three aspects is balanced only approximately.
 *
 *	The program does not compute anything meaningfull, but it is
