/*	EVERBODY:	Please read "APOLOGY" below. -rick 01/06/86 *			See introduction in net.arch, or net.micro * *	"DHRYSTONE" Benchmark Program * *	Version:	C/1.1, 12/01/84 * *	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. *		 * RESULTS BEGIN HERE * *----------------DHRYSTONE VERSION 1.1 RESULTS BEGIN-------------------------- * * MACHINE	MICROPROCESSOR	OPERATING	COMPILER	DHRYSTONES/SEC. * TYPE				SYSTEM				NO REG	REGS * --------------------------	------------	-----------	--------------- * Apple IIe	65C02-1.02Mhz	DOS 3.3		Aztec CII v1.05i  37	  37 * -		Z80-2.5Mhz	CPM-80 v2.2	Aztec CII v1.05g  91	  91 * -		8086-8Mhz	RMX86 V6	Intel C-86 V2.0	 197	 203LM?? * IBM PC/XT	8088-4.77Mhz	COHERENT 2.3.43	Mark Williams	 259	 275 * -		8086-8Mhz	RMX86 V6	Intel C-86 V2.0	 287	 304 ?? * Fortune 32:16 68000-6Mhz	V7+sys3+4.1BSD  cc		 360	 346 * PDP-11/34A	w/FP-11C	UNIX V7m	cc		 406	 449 * Macintosh512	68000-7.7Mhz	Mac ROM O/S	DeSmet(C ware)	 625	 625 * VAX-11/750	w/FPA		UNIX 4.2BSD	cc		 831	 852 * DataMedia 932 68000-10Mhz	UNIX sysV	cc		 837	 888 * Plexus P35	68000-12.5Mhz	UNIX sysIII	cc		 835	 894 * ATT PC7300	68010-10Mhz	UNIX 5.0.3	cc		 973	1034 * Compaq II	80286-8Mhz	MSDOS 3.1	MS C 3.0 	1086	1140 LM * IBM PC/AT    80286-7.5Mhz    Venix/286 SVR2  cc              1159    1254 *15 * Compaq II	80286-8Mhz	MSDOS 3.1	MS C 3.0 	1190	1282 MM * MicroVAX II	-		Mach/4.3	cc		1361	1385 * DEC uVAX II	-		Ultrix-32m v1.1	cc		1385	1399 * Compaq II	80286-8Mhz	MSDOS 3.1	MS C 3.0 	1351	1428 * VAX 11/780	-		UNIX 4.2BSD	cc		1417	1441 * VAX-780/MA780		Mach/4.3	cc		1428	1470 * VAX 11/780	-		UNIX 5.0.1	cc 4.1.1.31	1650	1640 * Ridge 32C V1	-		ROS 3.3		Ridge C (older)	1628	1695 * Gould PN6005	-		UTX 1.1c+ (4.2)	cc		1732	1884 * Gould PN9080	custom ECL	UTX-32 1.1C	cc		4745	4992 * VAX-784	-		Mach/4.3	cc		5263	5555 &4 * VAX 8600	-		4.3 BSD		cc		6329	6423 * Amdahl 5860	-		UTS sysV	cc 1.22	       28735   28846 * IBM3090/200	-		?		?	       31250   31250 * * *----------------DHRYSTONE VERSION 1.0 RESULTS BEGIN-------------------------- * * MACHINE	MICROPROCESSOR	OPERATING	COMPILER	DHRYSTONES/SEC. * TYPE				SYSTEM				NO REG	REGS * --------------------------	------------	-----------	--------------- * Commodore 64	6510-1MHz	C64 ROM		C Power 2.8	  36	  36 * HP-110	8086-5.33Mhz	MSDOS 2.11	Lattice 2.14	 284	 284 * IBM PC/XT	8088-4.77Mhz	PC/IX		cc		 271	 294 * CCC 3205	-		Xelos(SVR2) 	cc		 558	 592 * Perq-II	2901 bitslice	Accent S5c 	cc (CMU)	 301	 301 * IBM PC/XT	8088-4.77Mhz	COHERENT 2.3.43	MarkWilliams cc  296	 317 * Cosmos	68000-8Mhz	UniSoft		cc		 305	 322 * IBM PC/XT	8088-4.77Mhz	Venix/86 2.0	cc		 297	 324 * DEC PRO 350  11/23           Venix/PRO SVR2  cc               299     325 * IBM PC	8088-4.77Mhz	MSDOS 2.0	b16cc 2.0	 310	 340 * PDP11/23	11/23           Venix (V7)      cc               320     358 * Commodore Amiga		?
