-
-	* 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  <hmt@cygnus.co.uk>
-
-	* 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  <hmt@cygnus.co.uk>
-
-	* 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.

-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
---------------------
-
-* Added -DFAST_UART to Makefile
- 
-
-version 1.6.1 24-10-95
---------------------
- 
-* 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?)
-
-* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
-
-version 1.2 13-07-95
---------------------
-
-* Fixed bug in interrupt handling (wrong interrupt selected when more that
-one interrupt pending)
-
-* Fixed updating of condition codes during logical instructions (carry and
-overflow were not reset)
-
-* Fixed bug in WRTBR (tt field was wrongly over-written)
-
-version 1.1 07-07-95
---------------------
-
-* Fixed several bugs in the interrupt handler and callback routines.
-(reported by Paul Warren, Alsys)

-
-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
-

-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 <f>	Set the simulated "system clock" to <f> 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 <program>' and debug as
-usual. 
-
-The native simulator commands can be reached using the GDB 'sim'
-command:
-
-sim <sis_command>
-
-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 <file>
-
-Execute a batch file of SIS commands.
-
-+bp <address>
-
-Adds an breakpoint at address <address>.
-
-bp
-
-Prints all breakpoints
-
--bp <num>
-
-Deletes breakpoint <num>. 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 <string>
-
-Print <string> to the simulator window.
-
-float
-
-Prints the FPU registers
-
-go <address> [inst_count]
-
-The go command will set pc to <address> and npc to <address> + 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  <file_name>
-
-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.
-

-/* Thanks to Mike Haertel and Jim Avera for this test.
-   Here is a matrix of mmap possibilities:
-	mmap private not fixed
-	mmap private fixed at somewhere currently unmapped
-	mmap private fixed at somewhere already mapped
-	mmap shared not fixed
-	mmap shared fixed at somewhere currently unmapped
-	mmap shared fixed at somewhere already mapped
-   For private mappings, we should verify that changes cannot be read()
-   back from the file, nor mmap's back from the file at a different
-   address.  (There have been systems where private was not correctly
-   implemented like the infamous i386 svr4.0, and systems where the
-   VM page cache was not coherent with the filesystem buffer cache
-   like early versions of FreeBSD and possibly contemporary NetBSD.)
-   For shared mappings, we should conversely verify that changes get
-   propogated back to all the places they're supposed to be.
-
-   Grep wants private fixed already mapped.
-   The main things grep needs to know about mmap are:
-   * does it exist and is it safe to write into the mmap'd area
-   * how to use it (BSD variants)  */

- * 1. In the host, all IEEE traps are masked
- * 2. After each simulated FPU instruction, check if any exception occured 
- *    by reading the exception bits from the host FPU status register 
- *    (get_accex()).
- * 3. Propagate any exceptions to the simulated FSR.
- * 4. Clear host exception bits
- *
- *
- * This can also be done using ieee_flags() library routine on sun.
