\`configure' configures this package to adapt to many kinds of systems. |
|
Usage: $0 [OPTION]... [VAR=VALUE]... |
|
To assign environment variables (e.g., CC, CFLAGS...), specify them as |
VAR=VALUE. See below for descriptions of some of the useful variables. |
|
Defaults for the options are specified in brackets. |
|
Configuration: |
-h, --help display this help and exit |
--help=short display options specific to this package |
--help=recursive display the short help of all the included packages |
-V, --version display version information and exit |
-q, --quiet, --silent do not print \`checking...' messages |
--cache-file=FILE cache test results in FILE [disabled] |
-C, --config-cache alias for \`--cache-file=config.cache' |
-n, --no-create do not create output files |
--srcdir=DIR find the sources in DIR [configure dir or \`..'] |
|

Installation directories: |
--prefix=PREFIX install architecture-independent files in PREFIX |
[$ac_default_prefix] |
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX |
[PREFIX] |
|
By default, \`make install' will install all the files in |
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify |
an installation prefix other than \`$ac_default_prefix' using \`--prefix', |
for instance \`--prefix=\$HOME'. |
|
For better control, use the options below. |
|
Fine tuning of the installation directories: |
--bindir=DIR user executables [EPREFIX/bin] |
--sbindir=DIR system admin executables [EPREFIX/sbin] |
--libexecdir=DIR program executables [EPREFIX/libexec] |
--datadir=DIR read-only architecture-independent data [PREFIX/share] |
--sysconfdir=DIR read-only single-machine data [PREFIX/etc] |
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com] |
--localstatedir=DIR modifiable single-machine data [PREFIX/var] |
--libdir=DIR object code libraries [EPREFIX/lib] |
--includedir=DIR C header files [PREFIX/include] |
--oldincludedir=DIR C header files for non-gcc [/usr/include] |
--infodir=DIR info documentation [PREFIX/info] |
--mandir=DIR man documentation [PREFIX/man] |

cat <<\_ACEOF |
|
Program names: |
--program-prefix=PREFIX prepend PREFIX to installed program names |
--program-suffix=SUFFIX append SUFFIX to installed program names |
--program-transform-name=PROGRAM run sed PROGRAM on installed program names |
|
System types: |
--build=BUILD configure for building on BUILD [guessed] |
--host=HOST cross-compile to build programs to run on HOST [BUILD] |
--target=TARGET configure for building compilers for TARGET [HOST] |

Optional Features: |
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no) |
--enable-FEATURE[=ARG] include FEATURE [ARG=yes] |
--enable-maintainer-mode Enable developer functionality. |
--enable-sim-bswap Use Host specific BSWAP instruction. |
--enable-sim-cflags=opts Extra CFLAGS for use in building simulator |
--enable-sim-debug=opts Enable debugging flags |
--enable-sim-stdio Specify whether to use stdio for console input/output. |
--enable-sim-trace=opts Enable tracing flags |
--enable-sim-profile=opts Enable profiling flags |
|
Some influential environment variables: |
CC C compiler command |
CFLAGS C compiler flags |
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a |
nonstandard directory <lib dir> |
CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have |
headers in a nonstandard directory <include dir> |
CPP C preprocessor |
|
Use these variables to override the choices made by `configure' or to help |
it to find libraries and programs with nonstandard names/locations. |

# intl sister-directory configuration rules. |

|
# The idea behind this macro is that there's no need to repeat all the |
# autoconf probes done by the intl directory - it's already done them |
# for us. In fact, there's no need even to look at the cache for the |
# answers. All we need to do is nab a few pieces of information. |
# The intl directory is set up to make this easy, by generating a |
# small file which can be sourced as a shell script; then we produce |
# the necessary substitutions and definitions for this directory. |

+
+ * configure.in: add termcap and -luser32 for host=cygwin
+ * configure: regenerate
+
+1999-02-11 Hugo Tyson
+
+ * exec.c (dispatch_instruction):
+ Correct the sense of the
+ if (!sparclite) {
+ sregs->trap = TRAP_UNIMP;
+ break;
+ }
+ clause that has been pasted around: it's correct in the SCAN and
+ DIVScc (divide step) cases (where it was probably originally
+ written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
+ ie. instructions only in the SPARC V8 or SPARClite 86x
+ architectures. It was also present when not required for SMUL,
+ SMULcc, UMUL, UMULcc instructions that are present in all
+ architectures.
+
+1999-01-25 Hugo Tyson
+
+ * interf.c (run_sim): Fix a bug in the main loop's handling of
+ annulled delay slot instructions. There is precedent for this
+ change; the _other_ main loop in sis.c gets it right according to
+ my reading of the code.
+
+ The bug is: if an interrupt happens when the next instruction
+ (at sregs->pc) is annulled, the trap is taken (by execute_trap())
+ with the current values of PC and NPC, so when the trap returns,
+ the annulled instruction is indeed executed. Another giveaway is
+ that the annul flag is cleared in execute_trap(): the information
+ is demonstrably discarded.
+
+ The solution is: perform annulling before looking for traps, in
+ fact it's neater to do annulling, see if there's an interrupt and
+ if not, do the instruction, then handle traps be they generated by
+ interrupts pending or by the instruction we might just have done.
+ That's what the sis.c one does.
+
+1999-01-20 Hugo Tyson
+
+ * sis.h: Add asr17 register for support of SparcLITE (at least the
+ Hitachi ones I find before me)
+
+ * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
+ sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
+ Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
+ (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
+ (init_regs): Initialize y and asr17.
+ NB: In instruction-set space, the Y register is asr0; the
+ instructions have different names for human reasons only.
+
+ * sis.c:
+ * interf.c: Set boolean mode variable dumbio if invoked with
+ argument "-dumbio" and mention it of verbose.
+ * erc32.c: if "dumbio" is set, do not assume that there is a
+ terminal type device attached to stdin/stdout. Do not set
+ buffering or mess with tcsetattr or do any read operations in
+ order to make UART interrupts; not input data is supported.
+ This is necessary to allow the sim to be used within the eCos
+ testing infrastructure where stdin/stdout are pipes to a TCL
+ program; the sim hangs otherwise.
+
+Thu Jul 23 07:17:03 1998 Mark Alexander
+
+ * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.
+
+Tue Jul 7 21:12:41 1998 Mark Alexander

+
+Tue Jun 2 15:20:35 1998 Mark Alexander
+
+ * interf.c (sim_open): Use revamped memory_read, which makes
+ byte-swapping unnecessary. Add -sparclite-board option for
+ emulating RAM found on typical SPARClite boards. Print
+ error message for unrecognized option.

+ (fetch_bytes, store_bytes): New helper functions for revamped

+
+Version 2.1 26-02-96
+--------------------
+
+* Fixed bug in "go" command.
+
+version 2.0 05-02-96
+--------------------
+
+* Fixed bug in interrupt force register (erc32.c).
+
+* Change file load function to use bfd_openr.
+
+* SIS should now be endian independent.
+
+version 1.8 24-11-95
+--------------------
+
+* Fixed FPU timing - some sequences of FPU instructions did not calculate
+ the resource dependencies right.
+
+* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
+ but no FPU trap is generated.
+
+version 1.7.1 31-10-95
+--------------------
+
+* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
+ the FPU stays in execute mode.
+
+* Corrected JMPL and RETT timing (these instructions takes two cycles).
+
+
+version 1.7 25-10-95
+--------------------
+
+* Interrupt during annuled instruction corrupted return address - fixed.
+
+
+version 1.6.2 25-10-95

+--------------------
+
+* Fixed bug in STDFQ which caused bus error
+
+
+version 1.6 02-10-95
+--------------------
+
+* Modified srt0.s to include code that initiates registers in IU and FPU
+ and initializes the data segment. The simulator 'load' command does not
+ longer initialize the data segment!
+
+* Corrected MEC timer operation; scalers now divide the frequency by
+ (scaler_value + 1).
+
+* MEC breakpoints are not checked during store operation
+
+
+version 1.5 14-09-95
+--------------------
+
+* Fixed some bugs in the cycle counting for IU & FPU instructions.
+
+* Fixed bug that allowed an annuled instruction to cause memory exception.
+
+* The *ws parameter in mem.c should now contain the number of waitstates
+ required by the memory access (was total number of cycles).
+
+* The supplied srt0.s now clears the BSS (thanks Joel).
+
+version 1.4 22-08-95
+--------------------
+
+* Added a '-g' switch to enable/disable the GNU readline(), which cause
+some problems on solaris 2.x machines.
+
+* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
+may suffer a bit ...
+
+NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
+
+version 1.3 26-07-95
+--------------------
+
+* Fixed bug in mulscc instruction (how could that ever have worked?)
+

+How to use SIS with GDB
+-----------------------
+
+1. Building GDB with SIS
+
+To build GDB with the SIS/ERC32 simulator, configure with option
+'--target sparc-erc32-aout' and build as usual.
+
+2. Attaching the simulator
+
+To attach GDB to the simulator, use:
+
+target sim [options] [files]
+
+The following options are supported:
+
+ -nfp Disable FPU. FPops will cause an FPU disabled trap.
+
+ -freq Set the simulated "system clock" to MHz.
+
+ -v Verbose mode.
+
+ -nogdb Disable GDB breakpoint handling (see below)
+
+The listed [files] are expected to be in aout format and will be
+loaded in the simulator memory prior. This could be used to load
+a boot block at address 0x0 if the application is linked to run
+from RAM (0x2000000).
+
+To start debugging a program type 'load ' and debug as
+usual.
+
+The native simulator commands can be reached using the GDB 'sim'
+command:
+
+sim
+
+Direct simulator commands during a GDB session must be issued
+with care not to disturb GDB's operation ...
+
+For info on supported ERC32 functionality, see README.sis.
+
+
+3. Loading aout files
+
+The GDB load command loads an aout file into the simulator
+memory with the data section starting directly after the text
+section regardless of wich start address was specified for the data
+at link time! This means that your applications either has to include
+a routine that initialise the data segment at the proper address or
+link with the data placed directly after the text section.
+
+A copying routine is fairly simple, just copy all data between
+_etext and _data to a memory loaction starting at _environ. This
+should be done at the same time as the bss is cleared (in srt0.s).
+
+
+4. GDB breakpoint handling
+
+GDB inserts breakpoint in the form of the 'ta 1' instruction. The
+GDB-integrated simulator will therefore recognize the breakpoint
+instruction and return control to GDB. If the application uses
+'ta 1', the breakpoint detection can be disabled with the -nogdb
+switch. In this case however, GDB breakpoints will not work.

+
+SIS - Sparc Instruction Simulator README file (v2.0, 05-02-1996)
+-------------------------------------------------------------------
+
+1. Introduction
+
+The SIS is a SPARC V7 architecture simulator. It consist of two parts,
+the simulator core and a user defined memory module. The simulator
+core executes the instructions while the memory module emulates memory
+and peripherals.
+
+2. Usage
+
+The simulator is started as follows:
+
+sis [-uart1 uart_device1] [-uart2 uart_device2]
+ [-nfp] [-freq frequency] [-c batch_file] [files]
+
+The default uart devices for SIS are /dev/ptypc and /dev/ptypd. The
+-uart[1,2] switch can be used to connect the uarts to other devices.
+Use 'tip /dev/ttypc' to connect a terminal emulator to the uarts.
+The '-nfp' will disable the simulated FPU, so each FPU instruction will
+generate a FPU disabled trap. The '-freq' switch can be used to define
+which "frequency" the simulator runs at. This is used by the 'perf'
+command to calculated the MIPS figure for a particular configuration.
+The give frequency must be an integer indicating the frequency in MHz.
+
+The -c option indicates that sis commands should be read from 'batch_file'
+at startup.
+
+Files to be loaded must be in one of the supported formats (see INSTALLATION),
+and will be loaded into the simulated memory. The file formats are
+automatically recognised.
+
+The script 'startsim' will start the simulator in one xterm window and
+open a terminal emulator (tip) connected to the UART A in a second
+xterm window. Below is description of commands that are recognized by
+the simulator. The command-line is parsed using GNU readline. A command
+history of 64 commands is maintained. Use the up/down arrows to recall
+previous commands. For more details, see the readline documentation.
+
+batch
+
+Execute a batch file of SIS commands.
+
++bp
+
+Adds an breakpoint at address .
+
+bp
+
+Prints all breakpoints
+
+-bp
+
+Deletes breakpoint . Use 'bp' to see which number is assigned to the
+breakpoints.
+
+cont [inst_count]
+
+Continue execution at present position, optionally for [inst_count]
+instructions.
+
+dis [addr] [count]
+
+Disassemble [count] instructions at address [addr]. Default values for
+count is 16 and addr is the present address.
+
+echo
+
+Print to the simulator window.
+
+float
+
+Prints the FPU registers
+
+go [inst_count]
+
+The go command will set pc to and npc to + 4, and start
+execution. No other initialisation will be done. If inst_count is given,
+execution will stop after the specified number of instructions.
+
+help
+
+Print a small help menu for the SIS commands.
+
+hist [trace_length]
+
+Enable the instruction trace buffer. The 'trace_length' last executed
+instructions will be placed in the trace buffer. A 'hist' command without
+a trace_length will display the trace buffer. Specifying a zero trace
+length will disable the trace buffer.
+
+load
+
+Loads a file into simulator memory.
+
+mem [addr] [count]
+
+Display memory at [addr] for [count] bytes. Same default values as above.
+
+quit
+
+Exits the simulator.
+
+perf [reset]
+
+The 'perf' command will display various execution statistics. A 'perf reset'
+command will reset the statistics. This can be used if statistics shall
+be calculated only over a part of the program. The 'run' and 'reset'
+command also resets the statistic information.
+
+reg [reg_name] [value]
+
+Prints and sets the IU regiters. 'reg' without parameters prints the IU
+registers. 'reg [reg_name] [value]' sets the corresponding register to
+[value]. Valid register names are psr, tbr, wim, y, g1-g7, o0-o7 and
+l0-l7.
+
+reset
+
+Performs a power-on reset. This command is equal to 'run 0'.
+
+run [inst_count]
+
+Resets the simulator and starts execution from address 0. If an instruction
+count is given (inst_count), the simulator will stop after the specified
+number of instructions. The event queue is emptied but any set breakpoints
+remain.
+
+step
+
+Equal to 'trace 1'
+
+tra [inst_count]
+
+Starts the simulator at the present position and prints each instruction
+it executes. If an instruction count is given (inst_count), the simulator
+will stop after the specified number of instructions.
+
+Typing a 'Ctrl-C' will interrupt a running simulator.
+
+Short forms of the commands are allowed, e.g 'c' 'co' or 'con' are all
+interpreted as 'cont'.
+
+
+3. Simulator core
+
+The SIS emulates the behavior of the 90C601E and 90C602E sparc IU and
+FPU from Matra MHS. These are roughly equivalent to the Cypress C601
+and C602. The simulator is cycle true, i.e a simulator time is
+maintained and inremented according the IU and FPU instruction timing.
+The parallel execution between the IU and FPU is modelled, as well as
+stalls due to operand dependencies (FPU). The core interacts with the
+user-defined memory modules through a number of functions. The memory
+module must provide the following functions:
+
+int memory_read(asi,addr,data,ws)
+int asi;
+unsigned int addr;
+unsigned int *data;
+int *ws;
+
+int memory_write(asi,addr,data,sz,ws)
+int asi;
+unsigned int addr;
+unsigned int *data;
+int sz;
+int *ws;
+
+int sis_memory_read(addr, data, length)
+unsigned int addr;
+char *data;
+unsigned int length;
+
+int sis_memory_write(addr, data, length)
+unsigned int addr;
+char *data;
+unsigned int length;
+
+int init_sim()
+
+int reset()
+
+int error_mode(pc)
+unsigned int pc;
+
+memory_read() is used by the simulator to fetch instructions and
+operands. The address space identifier (asi) and address is passed as
+parameters. The read data should be assigned to the data pointer
+(*data) and the number of waitstate to *ws. 'memory_read' should return
+0 on success and 1 on failure. A failure will cause a data or
+instruction fetch trap. memory_read() always reads one 32-bit word.
+
+sis_memory_read() is used by the simulator to display and disassemble
+memory contants. The function should copy 'length' bytes of the simulated
+memory starting at 'addr' to '*data'.
+The sis_memory_read() should return 1 on success and 0 on failure.
+Failure should only be indicated if access to unimplemented memory is attempted.
+
+memory_write() is used to write to memory. In addition to the asi
+and address parameters, the size of the written data is given by 'sz'.
+The pointer *data points to the data to be written. The 'sz' is coded
+as follows:
+
+ sz access type
+ 0 byte
+ 1 halfword
+ 2 word
+ 3 double-word
+
+If a double word is written, the most significant word is in data[0] and
+the least significant in data[1].
+
+sis_memory_write() is used by the simulator during loading of programs.
+The function should copy 'length' bytes from *data to the simulated
+memory starting at 'addr'. sis_memory_write() should return 1 on
+success and 0 on failure. Failure should only be indicated if access
+to unimplemented memory is attempted. See erc32.c for more details
+on how to define the memory emulation functions.
+
+The 'init_sim' is called once when the simulator is started. This function
+should be used to perform initialisations of user defined memory or
+peripherals that only have to be done once, such as opening files etc.
+
+The 'reset' is called every time the simulator is reset, i.e. when a
+'run' command is given. This function should be used to simulate a power
+on reset of memory and peripherals.
+
+error_mode() is called by the simulator when the IU goes into error mode,
+typically if a trap is caused when traps are disabled. The memory module
+can then take actions, such as issue a reset.
+
+sys_reset() can be called by the memory module to reset the simulator. A
+reset will empty the event queue and perform a power-on reset.
+
+4. Events and interrupts
+
+The simulator supports an event queue and the generation of processor
+interrupts. The following functions are available to the user-defined
+memory module:
+
+event(cfunc,arg,delta)
+void (*cfunc)();
+int arg;
+unsigned int delta;
+
+set_int(level,callback,arg)
+int level;
+void (*callback)();
+int arg;
+
+clear_int(level)
+int level;
+
+sim_stop()
+
+The 'event' functions will schedule the execution of the function 'cfunc'
+at time 'now + delta' clock cycles. The parameter 'arg' is passed as a
+parameter to 'cfunc'.
+
+The 'set_int' function set the processor interrupt 'level'. When the interrupt
+is taken, the function 'callback' is called with the argument 'arg'. This
+will also clear the interrupt. An interrupt can be cleared before it is
+taken by calling 'clear_int' with the appropriate interrupt level.
+
+The sim_stop function is called each time the simulator stops execution.
+It can be used to flush buffered devices to get a clean state during
+single stepping etc.
+
+See 'erc32.c' for examples on how to use events and interrupts.
+
+5. Memory module
+
+The supplied memory module (erc32.c) emulates the functions of memory and
+the MEC asic developed for the 90C601/2. It includes the following functions:
+
+* UART A & B
+* Real-time clock
+* General purpose timer
+* Interrupt controller
+* Breakpoint register
+* Watchpoint register
+* 512 Kbyte ROM
+* 4 Mbyte RAM
+
+See README.erc32 on how the MEC functions are emulated. For a detailed MEC
+specification, look at the ERC32 home page at URL:
+
+http://www.estec.esa.nl/wsmwww/erc32
+
+6. Compile and linking programs
+
+The directory 'examples' contain some code fragments for SIS.
+The script gccx indicates how the native sunos gcc and linker can be used
+to produce executables for the simulator. To compile and link the provided
+'hello.c', type 'gccx hello.c'. This will build the executable 'hello'.
+Start the simulator by running 'startsim hello', and issue the command 'run.
+After the program is terminated, the IU will be force to error mode through
+a software trap and halt.
+
+The programs are linked with a start-up file, srt0.S. This file includes
+the traptable and window underflow/overflow trap routines.
+
+7. IU and FPU instruction timing.
+
+The simulator provides cycle true simulation. The following table shows
+the emulated instruction timing for 90C601E & 90C602E:
+
+Instructions Cycles
+
+jmpl, rett 2
+load 2
+store 3
+load double 3
+store double 4
+other integer ops 1
+fabs 2
+fadds 4
+faddd 4
+fcmps 4
+fcmpd 4
+fdivs 20
+fdivd 35
+fmovs 2
+fmuls 5
+fmuld 9
+fnegs 2
+fsqrts 37
+fsqrtd 65
+fsubs 4
+fsubd 4
+fdtoi 7
+fdots 3
+fitos 6
+fitod 6
+fstoi 6
+fstod 2
+
+The parallel operation between the IU and FPU is modelled. This means
+that a FPU instruction will execute in parallel with other instructions as
+long as no data or resource dependency is detected. See the 90C602E data
+sheet for the various types of dependencies. Tracing using the 'trace'
+command will display the current simulator time in the left column. This
+time indicates when the instruction is fetched. If a dependency is detetected,
+the following fetch will be delayed until the conflict is resolved.
+
+The load dependency in the 90C601E is also modelled - if the destination
+register of a load instruction is used by the following instruction, an
+idle cycle is inserted.
+
+8. FPU implementation
+
+The simulator maps floating-point operations on the hosts floating point
+capabilities. This means that accuracy and generation of IEEE exceptions is
+host dependent.

+
+1. MEC and ERC32 emulation
+
+The file 'erc32.c' contains a model of the MEC, 512 K rom and 4 M ram.
+
+The following paragraphs outline the implemented MEC functions.
+
+1.1 UARTs
+
+The UARTs are connected to two pseudo-devices, /dev/ttypc and /dev/ttypd.
+The following registers are implemeted:
+
+- UART A RX and TX register (0x01f800e0)
+- UART B RX and TX register (0x01f800e4)
+- UART status register (0x01f800e8)
+
+To speed up simulation, the UARTs operate at approximately 115200 baud.
+The UARTs generate interrupt 4 and 5 after each received or transmitted
+character. The error interrupt is generated if overflow occurs - other
+errors cannot occure.
+
+1.2 Real-time clock and general pupose timer A
+
+The following registers are implemeted:
+
+- Real-time clock timer (0x01f80080, read-only)
+- Real-time clock scaler program register (0x01f80084, write-only)
+- Real-time clock counter program register (0x01f80080, write-only)
+
+- Genearl pupose timer (0x01f80088, read-only)
+- Real-time clock scaler program register (0x01f8008c, write-only)
+- General purpose timer counter prog. register (0x01f80088, write-only)
+
+- Timer control register (0x01f80098, write-only)
+
+1.3 Interrupt controller
+
+The interrupt controller is implemented as in the MEC specification with
+the exception of the interrupt shape register. Since external interrupts
+are not possible, the interrupt shape register is not implemented. The
+only internal interrupts that are generated are the real-time clock,
+the general purpose timer and UARTs. However, all 15 interrupts
+can be tested via the interrupt force register.
+
+The following registers are implemeted:
+
+- Interrupt pending register (0x01f80048, read-only)
+- Interrupt mask register (0x01f8004c, read-write)
+- Interrupt clear register (0x01f80050, write-only)
+- Interrupt force register (0x01f80054, read-write)
+
+1.4 Breakpoint and watchpoint register
+
+The breakpoint and watchpoint functions are implemented as in the MEC
+specification. Traps are correctly generated, and the system fault status
+register is updated accordingly. Implemeted registers are:
+
+- Debug control register (0x01f800c0, read-write)
+- Breakpoint register (0x01f800c4, write-only)
+- Watchpoint register (0x01f800c8, write-only)
+- System fault status register (0x01f800a0, read-write)
+- Firts failing address register (0x01f800a4, read-write)
+
+
+1.5 Memory interface
+
+The following memory areas are valid for the ERC32 simulator:
+
+0x00000000 - 0x00080000 ROM (512 Kbyte, loaded at start-up)
+0x02000000 - 0x02400000 RAM (4 Mbyte, initialised to 0x0)
+0x01f80000 - 0x01f800ff MEC registers
+
+Access to unimplemented MEC registers or non-existing memory will result
+in a memory exception trap. However, access to unimplemented MEC registers
+in the area 0x01f80000 - 0x01f80100 will not cause a memory exception trap.
+The written value will be stored in a register and can be read back. It
+does however not affect the function in any way.
+
+The memory configuartion register is used to define available memory
+in the system. The fields RSIZ and PSIZ are used to set RAM and ROM
+size, the remaining fields are not used. NOTE: after reset, the MEC
+is set to decode 4 Kbyte of ROM and 256 Kbyte of RAM. The memory
+configuration register has to be updated to reflect the available memory.
+
+The waitstate configuration register is used to generate waitstates.
+This register must also be updated with the correct configuration after
+reset.
+
+The memory protection scheme is implemented - it is enabled through bit 3
+in the MEC control register.
+
+The following registers are implemeted:
+
+- MEC control register (bit 3 only) (0x01f80000, read-write)
+- Memory control register (0x01f80010, read-write)
+- Waitstate configuration register (0x01f80018, read-write)
+- Memory access register 0 (0x01f80020, read-write)
+- Memory access register 1 (0x01f80024, read-write)
+
+1.6 Watchdog
+
+The watchdog is implemented as in the specification. The input clock is
+always the system clock regardsless of WDCS bit in mec configuration
+register.
+
+The following registers are implemeted:
+
+- Watchdog program and acknowledge register (0x01f80060, write-only)
+- Watchdog trap door set register (0x01f80064, write-only)
+
+1.7 Software reset register
+
+Implemented as in the specification (0x01f800004, write-only).
+
+1.8 Power-down mode
+
+The power-down register (0x01f800008) is implemented as in the specification.
+However, if the simulator event queue is empty, power-down mode is not
+entered since no interrupt would be generated to exit from the mode. A
+Ctrl-C in the simulator window will exit the power-down mode.
+
+1.9 MEC control register
+
+The following bits are implemented in the MEC control register:
+
+Bit Name Function
+0 PRD Power-down mode enable
+1 SWR Soft reset enable
+3 APR Access protection enable

--- NEWS (nonexistent)
+++ NEWS (revision 223)
@@ -0,0 +1,108 @@
+
+version 2.0 05-02-96
+--------------------
+
+* Switched to bfd library. Any supported format (elf, coff, ...) can be used.
+* The UART devices can be set through -uart1 and -uart2 switches.
+* Switched to GNU readline.
+* Added -c option to run batch files at startup
+* 'reg' command can show different register windows (eg 'reg w3').
+* Use 'help' for online help on simulator commands
+
+version 1.8.1 20-01-96
+--------------------
+
+* added -mevrev0 switch to simulate MEC rev.0 bugs in timer and uart
+
+* added -iurev0 switch to simulate IU rev.0 jmpl/restore bug
+
+* Added sis command 'batch' to run batch files
+
+
+version 1.8 30-10-95
+--------------------
+
+* Added s-record support. Use the '-s' switch with sis or the 'load' command.
+
+* IU load dependencies are now modelled
+
+version 1.7 30-10-95
+--------------------
+
+* Power-down mode implemented in erc32.c.
+
+* Performance display shows the ratio between simulator-time and real-time.
+
+
+version 1.6.2 25-10-95
+--------------------
+
+* The UARTs can now be run at a given speed (simulator time) to better
+ simulate the behaviour of interrupt routines. The "true mode" is
+ selected through a compile switch in the makefile.
+
+
+version 1.6 28-09-95
+--------------------
+
+* Major reorganisation of the code. mec.c and mem.c merged into erc32.c.
+
+* The load command does NOT longer load the initialised data at an address
+ defined by .bdata. This is done in srt0.s using _environ.
+
+* Additional MEC functionallity added - software reset, memory access
+ protection and waitstate configuration register.
+
+* interf.c - a GDB interface added
+
+* -v switch (verbose) added
+
+version 1.5 14-09-95
+--------------------
+
+* Added a instruction trace buffer, enabled through the 'hist' command.
+
+* Added a 'perf' command to display statistics such as instruction mix,
+ CPI, FPU holds etc.
+
+* Added -nfp switch to disable FPU.
+
+* Added -freq switch to set simulated frequency.
+
+version 1.4 22-08-95
+--------------------
+
+* A -g is provided for those who have problems with GNU readline().
+
+version 1.3 26-07-95
+--------------------
+
+* No major news, just a bug fix release ...
+
+
+version 1.2 13-07-95
+--------------------
+
+* Added setting of IU registers through the 'reg' command. See README.
+
+* The GNU readline() function is used for command input. However, a
+ctrl-D still kills the simulator ...
+
+
+version 1.1 07-07-95
+--------------------
+
+
+* Added a 'go' command
+
+* Added cycle counting for interrupt overhead.
+
+* Function 'get_mem_ptr' takes one more parameter to avoid segmentation
+ faults if a.out files are loaded outside the simulated memory. See README.
+
+* Added user-defined function sim_stop().
+
+* Added a reset command. See README.
+
+* Implemented buffered output for MEC uarts to improve output speed.
