/* INTRODUCTION
 
The or1ksim have various parameters, which can be set in configuration
files. Multiple configurations may be used and switched between at
or1ksim startup.
By default, or1ksim loads condfiguration file from './sim.cfg' and if not
found it checks '~/.or1k/sim.cfg'. If even this file is not found or
all parameters are not defined, default configuration is used.
Users should not rely on default configuration, but rather redefine all
critical settings, since default configuration may differ in newer
versions of the or1ksim.
If multiple configurations are used, user can switch between them by
supplying -f <filename.cfg> option when starting simulator.
 
This file may contain (standard C) only comments - no // support.
Configure files can also be included, using:
include "file_name_to_include"
 
Like normal configuration file, this file is divided in sections,
where each section is described in detail also.
 
Some section also have subsections. One example of such subsection is
block:
 
device <index>
instance specific parameters...
enddevice
 
which creates a device instance.

* "DHRYSTONE" Benchmark Program
* -----------------------------
*
* Version: C, Version 2.1
*
* File: dhry.h (part 1 of 3)
*
* Date: May 25, 1988
*
* Author: Reinhold P. Weicker
* Siemens AG, AUT E 51
* Postfach 3220
* 8520 Erlangen
* Germany (West)
* Phone: [+49]-9131-7-20330
* (8-17 Central European Time)
* Usenet: ..!mcsun!unido!estevax!weicker
*
* Original Version (in Ada) published in
* "Communications of the ACM" vol. 27., no. 10 (Oct. 1984),
* pp. 1013 - 1030, together with the statistics
* on which the distribution of statements etc. is based.
*
* In this C version, the following C library functions are used:
* - strcpy, strcmp (inside the measurement loop)
* - printf, scanf (outside the measurement loop)
* In addition, Berkeley UNIX system calls "times ()" or "time ()"
* are used for execution time measurement. For measurements
* on other systems, these calls have to be changed.
*
* Updated January, 1997 Rick Cramer, Galileo(R) to work with
* the i960jx and Galileo-5 Reference Design.
*
*
* Collection of Results:
* Reinhold Weicker (address see above) and
*
* Rick Richardson
* PC Research. Inc.
* 94 Apple Orchard Drive
* Tinton Falls, NJ 07724
* Phone: (201) 389-8963 (9-17 EST)
* Usenet: ...!uunet!pcrat!rick
*
* Please send results to Rick Richardson and/or Reinhold Weicker.
* Complete information should be given on hardware and software used.
* Hardware information includes: Machine type, CPU, type and size
* of caches; for microprocessors: clock frequency, memory speed
* (number of wait states).
* Software information includes: Compiler (and runtime library)
* manufacturer and version, compilation switches, OS version.
* The Operating System version may give an indication about the
* compiler; Dhrystone itself performs no OS calls in the measurement loop.
*
* The complete output generated by the program should be mailed
* such that at least some checks for correctness can be made.
*
***************************************************************************
*
* History: This version C/2.1 has been made for two reasons:
*
* 1) There is an obvious need for a common C version of
* Dhrystone, since C is at present the most popular system
* programming language for the class of processors
* (microcomputers, minicomputers) where Dhrystone is used most.
* There should be, as far as possible, only one C version of
* Dhrystone such that results can be compared without
* restrictions. In the past, the C versions distributed
* by Rick Richardson (Version 1.1) and by Reinhold Weicker
* had small (though not significant) differences.
*
* 2) As far as it is possible without changes to the Dhrystone
* statistics, optimizing compilers should be prevented from
* removing significant statements.
*
* This C version has been developed in cooperation with
* Rick Richardson (Tinton Falls, NJ), it incorporates many
* ideas from the "Version 1.1" distributed previously by
* him over the UNIX network Usenet.
* I also thank Chaim Benedelac (National Semiconductor),
* David Ditzel (SUN), Earl Killian and John Mashey (MIPS),
* Alan Smith and Rafael Saavedra-Barrera (UC at Berkeley)
* for their help with comments on earlier versions of the
* benchmark.
*
* Changes: In the initialization part, this version follows mostly
* Rick Richardson's version distributed via Usenet, not the
* version distributed earlier via floppy disk by Reinhold Weicker.
* As a concession to older compilers, names have been made
* unique within the first 8 characters.
* Inside the measurement loop, this version follows the
* version previously distributed by Reinhold Weicker.
*
* At several places in the benchmark, code has been added,
* but within the measurement loop only in branches that
* are not executed. The intention is that optimizing compilers
* should be prevented from moving code out of the measurement
* loop, or from removing code altogether. Since the statements
* that are executed within the measurement loop have NOT been
* changed, the numbers defining the "Dhrystone distribution"
* (distribution of statements, operand types and locality)
* still hold. Except for sophisticated optimizing compilers,
* execution times for this version should be the same as
* for previous versions.
*
* Since it has proven difficult to subtract the time for the
* measurement loop overhead in a correct way, the loop check
* has been made a part of the benchmark. This does have
* an impact - though a very minor one - on the distribution
* statistics which have been updated for this version.
*
* All changes within the measurement loop are described
* and discussed in the companion paper "Rationale for
* Dhrystone version 2".
*
* Because of the self-imposed limitation that the order and
* distribution of the executed statements should not be
* changed, there are still cases where optimizing compilers
* may not generate code for some statements. To a certain
* degree, this is unavoidable for small synthetic benchmarks.
* Users of the benchmark are advised to check code listings
* whether code is generated for all statements of Dhrystone.
*
* Version 2.1 is identical to version 2.0 distributed via
* the UNIX network Usenet in March 1988 except that it corrects
* some minor deficiencies that were found by users of version 2.0.
* The only change within the measurement loop is that a
* non-executed "else" part was added to the "if" statement in
* Func_3, and a non-executed "else" part removed from Proc_3.
*
***************************************************************************
*
* Defines: The following "Defines" are possible:
* -DREG=register (default: Not defined)
* As an approximation to what an average C programmer
* might do, the "register" storage class is applied
* (if enabled by -DREG=register)
* - for local variables, if they are used (dynamically)
* five or more times
* - for parameters if they are used (dynamically)
* six or more times
* Note that an optimal "register" strategy is
* compiler-dependent, and that "register" declarations
* do not necessarily lead to faster execution.
* -DNOSTRUCTASSIGN (default: Not defined)
* Define if the C compiler does not support
* assignment of structures.
* -DNOENUMS (default: Not defined)
* Define if the C compiler does not support
* enumeration types.
* -DICACHEON (default: Not defined)
* Adjust performace by conditionally compiling
* these i960jx CACHE paramaters.
* -DICACHEOFF
* -DDCACHEON (default: Not defined)
* -DDCACHEOFF
*
* NOTE: Galileo-5 Board Frequency is set to 33Mhz in the
* file jx-timer.c. If the operating frequency is
* changed by replacing the crystal, then this #define
* must also be changed.
*
***************************************************************************
*
* Compilation model and measurement (IMPORTANT):
*
* This C version of Dhrystone consists of four files:
* - dhry.h (this file, containing global definitions and comments)
* - dhry_1.c (containing the code corresponding to Ada package Pack_1)
* - dhry_2.c (containing the code corresponding to Ada package Pack_2)
* - jx-timer.c (containing the code to access the i960jx timer)
*
* The following "ground rules" apply for measurements:
* - No procedure merging
* - Otherwise, compiler optimizations are allowed but should be indicated
* - Default results are those without register declarations
* See the companion paper "Rationale for Dhrystone Version 2" for a more
* detailed discussion of these ground rules.
*
* For 16-Bit processors (e.g. 80186, 80286), times for all compilation
* models ("small", "medium", "large" etc.) should be given if possible,
* together with a definition of these models for the compiler system used.
*
* Example Intel 960jx compile syntax for Galileo-5.
*
* ic960 -AJA -Tgal5 -O2 -DREG=register dhry_1.c dhry_2.c jx-timer.c
*
**************************************************************************
*
* Dhrystone (C version) statistics:
*
* [Comment from the first distribution, updated for version 2.
* Note that because of language differences, the numbers are slightly
* different from the Ada version.]
*
* The following program contains statements of a high level programming
* language (here: C) in a distribution considered representative:
*
* assignments 52 (51.0 %)
* control statements 33 (32.4 %)
* procedure, function calls 17 (16.7 %)
*
* 103 statements are dynamically executed. The program is balanced with
* respect to the three aspects:
*
* - statement type
* - operand type
* - operand locality
* operand global, local, parameter, or constant.
*
* The combination of these three aspects is balanced only approximately.
*
* 1. Statement Type:
* ----------------- number
*
* V1 = V2 9
* (incl. V1 = F(..)
* V = Constant 12
* Assignment, 7
* with array element
* Assignment, 6
* with record component
* --
* 34 34
*
* X = Y +|-|"&&"|"|" Z 5
* X = Y +|-|"==" Constant 6
* X = X +|- 1 3
* X = Y *|/ Z 2
* X = Expression, 1
* two operators
* X = Expression, 1
* three operators
* --
* 18 18
*
* if .... 14
* with "else" 7
* without "else" 7
* executed 3
* not executed 4
* for ... 7 | counted every time
* while ... 4 | the loop condition
* do ... while 1 | is evaluated
* switch ... 1
* break 1
* declaration with 1
* initialization
* --
* 34 34
*
* P (...) procedure call 11
* user procedure 10
* library procedure 1
* X = F (...)
* function call 6
* user function 5
* library function 1
* --
* 17 17
* ---
* 103
*
* The average number of parameters in procedure or function calls
* is 1.82 (not counting the function values as implicit parameters).
*
*
* 2. Operators
* ------------
* number approximate
* percentage
*
* Arithmetic 32 50.8
*
* + 21 33.3
* - 7 11.1
* * 3 4.8
* / (int div) 1 1.6
*
* Comparison 27 42.8
*
* == 9 14.3
* /= 4 6.3
* > 1 1.6
* < 3 4.8
* >= 1 1.6
* <= 9 14.3
*
* Logic 4 6.3
*
* && (AND-THEN) 1 1.6
* | (OR) 1 1.6
* ! (NOT) 2 3.2
*
* -- -----
* 63 100.1
*
*
* 3. Operand Type (counted once per operand reference):
* ---------------
* number approximate
* percentage
*
* Integer 175 72.3 %
* Character 45 18.6 %
* Pointer 12 5.0 %
* String30 6 2.5 %
* Array 2 0.8 %
* Record 2 0.8 %
* --- -------
* 242 100.0 %
*
* When there is an access path leading to the final operand (e.g. a record
* component), only the final data type on the access path is counted.
*
*
* 4. Operand Locality:
* -------------------
* number approximate
* percentage
*
* local variable 114 47.1 %
* global variable 22 9.1 %
* parameter 45 18.6 %
* value 23 9.5 %
* reference 22 9.1 %
* function result 6 2.5 %
* constant 55 22.7 %
* --- -------
* 242 100.0 %
*
*
* The program does not compute anything meaningful, but it is syntactically
* and semantically correct. All variables have a value assigned to them
* before they are used as a source operand.
*
* There has been no explicit effort to account for the effects of a
* cache, or to balance the use of long or short displacements for code or
* data.

DESCRIPTION
<<vprintf>>, <<vfprintf>>, <<vsprintf>> and <<vsnprintf>> are (respectively)
variants of <<printf>>, <<fprintf>>, <<sprintf>> and <<snprintf>>. They differ
only in allowing their caller to pass the variable argument list as a
<<va_list>> object (initialized by <<va_start>>) rather than directly
accepting a variable number of arguments.
 
RETURNS
The return values are consistent with the corresponding functions:
<<vsprintf>> returns the number of bytes in the output string,
save that the concluding <<NULL>> is not counted.
<<vprintf>> and <<vfprintf>> return the number of characters transmitted.
If an error occurs, <<vprintf>> and <<vfprintf>> return <<EOF>>. No
error returns occur for <<vsprintf>>.
 
PORTABILITY
ANSI C requires all three functions.
 
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
