早期freebsd实现

/****** A Version of the famous dhrystone benchmark ******* */
/* 
 Sun Oct  1 10:40:53 1989  Doug Lea  (dl at g.oswego.edu)
 Changes made to the standard version to run under C++:

 * include standard  prototypes for printf and exit
 * include Int.h and Char.h
 * convert all `int' and `char' to `Int' and `Char' 
    (except those needed for timing)
 * predeclare all functions
 * convert all function headers from old-C
 * Change name of struct tms tms to Tms
 * wrote mystrcpy and mystrcmp to handle Chars, not chars
 * added coercion to bad-looking Proc3 call in Proc1
 * initialized String1Loc in Proc0
 * use `new' instead of malloc


This program is marginally useful in looking at the effects of various
C++ constructs when defining a heavily constructive class like
Int and Char. The Int.h and Char.h files can be compiled several
ways, as listed at the top of each

 *	"DHRYSTONE" Benchmark Program
 *
 *	Version:	C/1, 12/01/84
 *
 *	Date:		PROGRAM updated 11/02/85, RESULTS updated 12/13/85
 *
 *	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,vax135,..}!houxm!castor!pcrat!rer
 *
 *			and thanks to all that do.  Space prevents listing
 *			the names of those who have provided some of these
 *			results.
 *
 *	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.  I'm not going
 *			to list a compiler in a better place because if it
 *			had register variables it might do better. No
 *			register variables is a big loss in my book.
 *
 *	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.

 *
 *	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.
