2005-09-02 Borut Razem <borut.razem@siol.net>
	* doc/gpsimWin32.html: linking with glib-2.6.6, gtk+-2.6.9, pango-1.8.2

2005-09-02 Manuel Bouyer <bouyer@antioche.eu.org>
	* src/16bit-registers.cc: PCL accesses were using program memory
	indexes instead of program memory addresses.
	* src/14bit-tmrs.cc: TMR2:current_value() would return the
	contents of PR2 even when configured for normal operation.
	* src/p18x.cc: typo in porte names.
	
2005-09-01 Manuel Bouyer <bouyer@antioche.eu.org>
	* src/p18x.cc: Fix crash when an 18F252	is instantiated.
	* src/gpsim_time.cc: Disabled unnecessary debug printing
	* src/uart.cc: Fixed spurious uart transmit. Add io sink for
	Receiver. 

2005-08-31 J.R. Heisey <jrheisey@sourceforge.com>
	* src/processor.cc: Fixed a crashing bug when the --source=disable
	option is used.

2005-08-30 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/input.cc: Created function parse_string_only() which
	will parse the passed in command string with out emptying
	existing commands from the buffer.
	Modified LLStack::GetNext() and LLStack::Pop() to not remove
	the last LLStack object.
	Fixed memory leak in LLStack::Pop().
	
	* cli/ui_gpsim.cc: Added EOL to injected abort_gpsim_now
	command.

2005-08-30 Scott Dattalo <scott@dattalo.com>
	* src/gpsim_time.h, src/gpsim_time.cc, bitlog.cc: Made the
	constant 'END_OF_TIME' part of the Cycle_Counter class. This is
	now used to initialize members of the ThreeStateLogger class.

2005-08-30 Scott Dattalo <scott@dattalo.com>
	* src/processor.h, src/processor.cc, src/pic_processor.cc: Fixed
	step-over feature for the 18F family.
	
2005-08-30 Scott Dattalo <scott@dattalo.com>
	* regression/rt.sh: The new version of the regression test script
	was not checked in yesterday. This new version creates a simple
	stc file and invokes a single regression test. It then checks to
	see if the test was successful.
	* regression/simulate, regression/create_stc: Removed from CVS.

2005-08-29 J.R. Heisey <jrheisey@sourceforge.com>
	* src/ioports.cc, src/ioports.h: Added PortModule::getPin().
	Fixed a few compiler warnings.

	src/src.vcproj: Added bit.cc and bit.h.

	src/stimuli.cc, src/symbol.cc, src/symbol.h: Changed references
	of IOPORT to PortRegister.

2005-08-29 Scott Dattalo <scott@dattalo.com>
	* modules/encoder.cc, modules/logic.cc, modules/paraface.cc,
	modules/push_button.cc, modules/switch.cc, src/i2c-ee.cc, src/p12x.cc
	IOPIN::update_direction method now has a refresh option.
	* src/ioports.h, src/ioports.cc:
	- Added several options to control when I/O pins refresh their state
	  information (with respect to stimuli that is).
	- PicPortBRegister::get () had the wrong parameter signature and
	thus was not getting invoked (the parent get() method was getting
	invoked instead).
	* modules/usart.cc: updating to new iopin api. Added new code and
	removed a bunch dead code and generally cleaned things up - it's
	still not working yet though.
	* src/12bit-processors.cc, src/12bit-processors.h, src/p16f62x.cc:
	pic-processor.cc, pic-processor.h, processor.h
	set_config_word now returns true if the config word address is
	successfully set.
	* src/pic-processor.cc: Fixed bug with
	init_program_memory_at_index() - it was not setting the
	configuration word if the address was in configuration memory.
	* src/bitlog.cc: Added a 'ThreeStateEventLogger' that's analogous
	to the bit and byte logger. 
	* src/intcon.cc: Turned off some debugging code.
	* src/registers.h: fixed typo in comment
	* src/stimuli.cc, src/stimuli.h: Iopin's were checking Z state
	before W state - this caused a W-state condition to be returned as
	a Z-state. In addition, the getDrivingState() was being checked as
	opposed to the getDrivenState().
	- Added getMonitor() method.
	* src/uart.h, src/uart.cc: Updating to new I/O pin design. And
	numerous changes to clean up and fix the code - this is still not
	working though.
	
2005-08-23 Scott Dattalo <scott@dattalo.com>
	* run_regression.sh, rt.sh: Redesigned the regression tests to
	make use of new gpsim scripting features. Also, all tests have
	been converted from absolute-mode to object-code mode.

2005-08-22 Scott Dattalo <scott@dattalo.com>
	* src/ioports.cc: Fixed typo in pullup in setDefaultPullupControl
	method. 

2005-08-21 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/input.cc, cli/input.h, gpsim/main.cc: Added two
	command options. Option -E will echo commands to the
	console. Useful for stc debugging. This will also
	display all the command line parameters. Useful when
	another tool launches gpsim but does not display the
	command line.

	gpsim/main.cc, src/init.cc: Option '-S disable' will
	prevent source code from being loaded. Usefule for
	automated regression testing. '-S enable' will enable
	source code loading. See online help.
	
	* src/p16x7x.cc: Fixed an sign/unsigned warning.

	* src/processor.h: Test function for whether source file
	is open.

	* src/sim_context.cc, src/sim_context.h: Added new
	global boolean property called EnableSourceLoad. Setting
	it to false will prevent source code from being loaded.
	Purpose is when gpsim is used for automated regression
	testing to speed things up.

	* src/stimuli.cc: Fixed a crashing bug when port()
	operator is used with out any module explicitly entered
	as a parameter.

	* src/symbol.h, src/value.h: Added findBoolean() to
	Symbol_Table.

	* src/value.h: Added a equals operator to Boolean.

2005-08-19 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/input.cc: Added code to allow stc files with <CR><LF>
	for Windows EOL to be read under Linux.

2005-08-18 J.R. Heisey <jrheisey@sourceforge.com>
	* src/processor.cc, src/processor.h, src/registers.cc,
	src/symbol.cc: Added two processor boolean attributes
	BreakOnValidRegisterRead and BreakOnInvalidRegisterWrite.

	* src/breakpoints.cc, src/breakpoints.h, src/cmd_gpsim.h,
	plat/win32/gpsim.def, cli/input.cc, cli/ui_gpsim.cc,
	gpsim/main.cc: Added -e or --exit command line option
	that accepts a parameter onbreak. This causes gpsim to
	exit when the simulation halts.

2005-08-11 Scott Dattalo <scott@dattalo.com>
	* src/breakpoints.cc, src/breakpoints.h: Allowed breakpoint 
	expressions for breakpoint instructions to act like assertions.
	* src/cmd_manager.h, src/cod.cc, src/gpsim_interface.h,
	  src/modules.cc, src/modules.h, cli/input.cc:
	Added the capability to run multiple module scripts.
	* cli/ui_gpsim.cc: Fixed bug guint64 formatted output.
	* regression/logic_test/Makefile, regression/logic_test/logic_test.asm:
	The new I/O port design more correctly implements I/O pins and
	this exposed a bug in the regression test. Also, this regression
	test was used to develop the multiple Module Script feature.

2005-08-11 J.R. Heisey <jrheisey@sourceforge.com>
	* src/stimuli.cc, src/stimuli.h, src/symbol.cc, src/symbol.h:
	Quick fix of when trying to attach an input data stimuli that
	was broken a couple of checkins ago.

2005-08-11 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.nsi: bump build number

2005-08-11 Scott Dattalo <scott@dattalo.com>
	* src/ioports.cc, src/ioports.h: Added the PeripheralSignalSource
	class to simplify the connection of I/O pins to peripherals. Also,
	added more documentation about the I/O port design.
	* src/p16x7x.h, src/p16x7x.cc, src/p16f87x.cc: The Analog to
	Digital convertor peripheral now connects to I/O pins again. Also,
	the A2D module was redesigned so that less of the internal
	implementation is exposed. 
	* src/14bit-tmrs.h, src/14bit-tmrs.cc, src/ssp.h, src/ssp.cc,
	src/p16x6x.cc: Updated the peripheral connections with the new
	PeripheralSignalSource class.

2005-08-10 J.R. Heisey <jrheisey@sourceforge.com>
	* src/stimuli.cc, src/stimuli.h, src/symbol.cc, src/symbol.h,
	cli/cmd_attach.cc, cli/cmd_attach.h, cli/parse.yy,
	cli/scan.ll, plat/win32/gpsim.def: Modified
	the attach command with the pin() and port() operators.
	Now you can use one of 4 variations of these operators to
	specify the module, port name and/or pin number that represents
	the underlying stimulus object. An example of how to use: if
	a pin number is defined as a program file symbol, you
	may use the symbol name in the port() or pin() operators.
	This way your STC file can be more generic and support a
	variety of firmware code files as long as you use the same
	symbol name for the pin. See the online help for more details.

	The pin() operator refers to package based pins. The port()
	operator refers to port based pins. Other stimulus may still
	be refered to using just the name of the stimulus.

	* src/attributes.cc: Changed a few global symbols so that
	Symbol_Table::Clear() does not remove them.

	* src/fopen-path.cc, src/fopen-path.h, gpsim/main.cc:
	Fixed -L source path command line option.
	Added code to support a gpsim SourcePath global string symbol
	that give command prompt access to the source search path.

	* src/ioports.h: Fixed a warning message about the destructor
	of PinModule not being virtual.

	* src/symbol.cc,h, cli/cmd_symbol.cc: Added the ability to
	use the '.' character as a trailing wild card in the symbol
	command. Example PIC. will list all symbols that begin with
	the letters PIC.

2005-08-04 Scott Dattalo <scott@dattalo.com>
	* gui/gui_breadboard.cc, src/symbol.h, src/symbol.cc,
	src/stimuli.cc:
	Verified that template issues with gcc 3.4.X have been resolved
	and removed a #define that had beed added to get around this.

2005-08-06 Scott Dattalo <scott@dattalo.com>
	* src/ssp.h, src/ssp.cc: Updated the SSP peripheral with the new
	I/O port API.
	* src/14bit-processors.h, src/p16f87x.cc, src/p16f87x.h,
	src/p16x6x.cc, src/p16x6x.h, src/p16x7x.cc, src/p16x7x.h: Updated
	to the new SSP API.

2005-08-04 J.R. Heisey <jrheisey@sourceforge.com>
	* symbol.cc, symbol.h: Fixed the template compile problems for
	gcc 3.4.4 due to new bugs in gcc. I didn't see this issue using
	gcc 3..3.3 on linux. I only have 3.4.4 version of the compiler
	under cygwin. I've left the #define commented out so someone can
	test it under linux before removing the #ifdef's.

2005-08-04 Scott Dattalo <scott@dattalo.com>
	* gui/gui_breadboard.cc, src/symbol.h, src/symbol.cc, src/stimuli.cc:
	Backed out some of the symbol changes made by JR because the code
	doesn't compile on Linux (gcc 3.4.2). At the moment, this means
	that stimuli and node dumps do not work. 

2005-08-04 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_node.cc, plat/win32/gpsim.def, gui/gui_breadboard.cc,
	modules/resistor.cc, src/stimuli.cc, src/stimuli.h,
	src/symbol.cc, src/symbol.h, src/value.h: Eliminated the
	node_list and stimulus_list. There are now Symbol_Table
	functions and iterators available for node_symbol and
	stimulus_symbol objects which contain Stimulus_Node and
	stimulus objects respectively.
	Adjusted the way stimulus and stimulus_Node objects are
	named. Unnamed objects are not put into the symbol table.
	The respective new_name() functions will add the objects
	into the symbol table appropriately. Removes several
	references that added these objects to the symbol table.

	Also modified the PullupResister to name the res IO_bi_directional
	i/o pin to pullupname + ".pin". Now the PullupResister
	exists in the symbol table as a module with what ever you
	named it. The pin is attribute of the PullupResister module.
	Whew!

2005-08-04 Scott Dattalo <scott@dattalo.com>
	* src/uart.cc, src/uart.h, src/p16x6x.cc, src/16bit-processors.cc,
	src/16bit-registers.cc, src/16bit-registers.h, src/p16f62x.cc:
	Add I/O source and sink connections to the usart peripheral. So
	now the usart is connected to I/O pins using the new I/O port design.

2005-08-02 J.R. Heisey <jrheisey@sourceforge.com>
	* src/os_dependent.cc, src/processor.cc,h, src/cod.cc,
	plat/win32/gpsim.def: Fixed a problem where loading a
	program file (no STC) using the GUI resulted source code
	not being found even though that source was in the same
	folder as the program file.

	* gui/gui_menu.cc: Fixed the display of cycle count in
	cycles where %Lx was used in a sprintf instead of the
	platform independent project macro PRINTF_INT64_MODIFIER.

2005-08-02 Scott Dattalo <scott@dattalo.com>
	* src/16bit-processors.cc, src/p18x.cc: The new I/O port register
	symbols were getting added to the symbol table twice. Also, the
	eeprom peripheral for some of the 18f devices was not getting
	created.

2005-08-02 J.R. Heisey <jrheisey@sourceforge.com>
	src/cmd_gpsim.h
	* src/cod.cc: Removed an error message from PicCodProgramFileType::
	open_a_file() that is handled externally.

	* src/registers.cc: Fixed a bug in RegisterValue::toString()
	not displaying enough digits.

	* src/value.h, src/symbol.h, src/registers.h, gui/gui_register.h:
	Added some conversion and equals operators.

	* cli/ui_gpsim.cc, src/cmd_gpsim.h: Added several string
	formatting routines.

	* plat/win32/gpsim.def: Updated for new pin I/o routines.

	* gui/gui_watch.cc, gui/gui_watch.h: Updated display of values
	to account for uninitialized bits and bit masked register
	symbols.

2005-08-01 Scott Dattalo <scott@dattalo.com>
	* src/p16x5x.h, src/p16x5x.cc: Upgraded the P16C54 and P16C55 to
	the new I/O port design.

	* src/16bit-processors.cc, src/16bit-registers.cc,
	src/16bit-registers.h, src/p18x.cc, src/p18x.h:
	Completed converting the 16-bit core I/O ports to the new I/O
	redesign (note - the peripheral-to-I/O mapping still needs to be
	completed). 

	* src/ioports.h, src/ioports.cc: deprecated the old PIC_IOPORT
	class and all of its children.
	
2005-08-01 Scott Dattalo <scott@dattalo.com>
	* src/14bit-processors.cc, src/14bit-processors.h,
	src/14bit-tmrs.cc, src/14bit-tmrs.h, src/intcon.cc, src/intcon.h,
	src/pir.h, src/p16x6x.cc, src/p16x6x.h, src/ioports.cc,
	src/ioports.h, src/p16x7x.cc, src/p12x.cc:

	-- The intcon and pir registers were not getting set up correctly for
	   the midrange devices.
	-- Added 'sinks' and 'sources' for the CCP module.
	
	* src/16bit-processors.cc, src/16bit-processors.h, src/p18x.cc,
	src/p18x.h: Began porting the new I/O port design to the 16bit
	core devices. 

	* src/symbol.cc: Added a diagnostic message that is printed
	whenever a register symbol with a null cpu is added to the symbol
	table.

	* regression/run_regression.sh, regression/p18f452_ports.asm,
	regression/p18f452_ports.stc:
	-- Added new regression test to test the P18F family I/O ports.
	-- Redesigned the processor construction sequence.
	-- The P18F1220 did not have PortB pullup resistors.

2005-07-30 J.R. Heisey <jrheisey@sourceforge.com>
	* src/symbol.cc, src/symbol.h: Added a list of symbols
	that are defined from the gpsim command line. The list
	and the symbol values are preserved when the symbol table
	is cleared due to a new processor being allocated.
	Removed the add() function that accepted a symbol type
	as a string. See comments for cmd_symbol.cc,h.

	* src/attributes.cc, src/sim_context.cc, src/sim_context.h:
	Changed or added calls to the symbol table.
	
	* cli/ui_gpsim.cc, src/cmd_gpsim.h: Added functions to render
	integer values to strings based on a system level defined
	radix. The radix will be exposed as a global attribute.
	There are distinct radix definitions for program addresses,
	RAM addresses and data values. Will expose a global attribute
	to define the prefix for displaying hexidecimal values. The
	default is '$'.

	* gpsim/main.cc: Added -D command line option for defining
	symbols and their values to be placed into the symbol
	table.

	* src/value.cc, src/value.h: Added string parsing and
	constructor functions for each data type. Used for
	the command line parsing of symbol definitions.

	* cli/cmd_symbol.cc,h, cli/cmd_load.cc,h, cli/parse.yy:
	The load command will now accept symbols as input for the
	filename. Combined with	the symbol defines on the command
	line, one STC file can be used to open any program file by
	defining a symbol on the gpsim command line and referencing
	that symbol in the load commmand.
	* The symbol command can now be used to create a symbol from
	the gpsim command prompt or an STC file. The syntax is
	symbol <newsymbol>=<value>. Types include string, integer,
	float and boolean.

	* gpsim/gpsim.vcproj, gui/gui_menu.cc, gui/gui_regwin.cc:
	Removed the references for gtk_file_selection_get_filename_utf8().
	This was added due to compile time issues with gtkextra-2.1
	under Visual Studio .NET. The VS.NET build links a gtkextra
	static lib into the exe. Even if you can get it to compile,
	sometimes gpsim will crash before its main() function is
	entered. The use of gtkextra-2.1 under VS.NET is not
	recommended and I have reverted the gpsim.vcproj back to
	gtkextra-2.0.

	* src/program_files.cc: Changed error handling logic
	to prevent a "list file not found" error from displaying
	in an inappropriate situation.

2005-07-29 Scott Dattalo <scott@dattalo.com>
	* src/ioports.cc, src/ioports.h, src/p12x.cc, src/p16x6x.cc,
	src/registers.h, src/stimuli.cc, src/stimuli.h, src/symbol.cc,
	src/tmr0.cc, src/tmr0.h:
	Introduced the concept of Multi-State logic to stimuli.


2005-07-15 J.R. Heisey <jrheisey@sourceforge.com>
	* src/symbol.cc: Added check to prevent a symbol name of a null string
	from being added as a symbol.

	* src/stimuli.cc: Added a check to prevent a IOPIN name null string
	pointer	from being added to the symbol table.

	* modules/resistor.cc: PullupResistor() constructor was setting
	its attribute before it had set its own name resulting in the
	attribute name not being scoped correctly.

	* src/breakpoints.cc, src/breakpoints.h, cli/cmd_break.cc,
	cli/cmd_break.h: Added code to support break expressions of
	the form (Reg & mask BoolOp value) where BoolOp includes
	<, >, <=, >= and != operators. Just need to change the print()
	and action() console output functions of the break classes and
	uncomment code in parse.yy.

2005-07-26 Scott Dattalo <scott@dattalo.com>
	* src/bit.h, src/bit.cc, src/Makefile.am: Added new files to
	handle a 'Bit' object. This code was formerly tucked away in
	registers.cc. 
	* src/stimuli.h, src/ioports.h, src/ioports.cc: Added a control
	object for the PinModule to handle I/O pin pullups. Also, added an
	option to prohibit certain stimulus updates whenever I/O pin state
	information changes.
	
2005-07-26 Scott Dattalo <scott@dattalo.com>
	* src/16bit-instructions.cc,
	regression/instructions_16bit/instructions_16bit.asm: Fixed bug
	with 16bit processors Table Read (more index vs address). Thanks
	to Peter Onion for pointing this (and other 16bit stuff out).
	
2005-07-26 Scott Dattalo <scott@dattalo.com>
	* src/i2c-ee.cc, src/i2c-ee.h, src/ioports.cc, src/ioports.h,
	src/p12x.cc, src/stimuli.cc, src/stimuli.h: Fixed 12CE51x internal
	eeprom peripheral. 
	* gui/gui_menu.cc, gui/gui_regwin.cc: Removed dependency on gtk
	win32 port.

2005-07-25 Scott Dattalo <scott@dattalo.com>
	* regression/instructions_16bit/instructions_16bit.asm: added
	tests for multi-word instructions.
	* regression/p12ce518/p12ce518.asm: debugging eeprom i2c interface
	* gui/gui_src_opcode.cc, src/16bit-instructions.cc,
	src/16bit-instructions.h: Fixed more problems with address <-->
	index mapping. (and there are still some issues remaing with the
	program memory viewer).
	* src/i2c-ee.cc, src/ioports.cc, src/ioports.h, src/p12x.cc,
	src/p12x.h: The eeprom i2c interface is broken...

	* gpsim/gpsim.vcproj, doc/gpsimWin32.html, plat/win32/gpsim.nsi:
	  use pthreads-w32-2-7-0-release
	* cli/scan.ll: corrected typo

2005-07-22 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_disasm.cc: rnages were disassembling wrong addresses
	* gui/gui_src_asm.cc: cleanup

	Implenting new ioport design for 12bit cores.
	Fixed bugs with resets.
	* src/16bit-hexdecode.cc, src/16bit-instructions.cc,
	  src/16bit-processors.h, src/16bit-registers.cc, src/cod.cc:
	16bit processors were not getting loaded properly due to some
	bugs with address <-> index mapping

2005-07-21 Scott Dattalo <scott@dattalo.com>
	* src/ioports.h, src/ioports.cc: classes derived from PortRegister
	can now specify the type of PinModule class.

	I/O Port Redesign: These files have been updated to accommodate a
	new I/O Port design. Currently the design applies only to the
	mid-range PIC family, but will be propogated to the 12 and 16 bit
	cores too.

	In summary, the I/O pins are now managed with I/O pin modules. A
	port register maintains an array of these modules. In the old
	design, the I/O pins were managed directly by the Port
	registers. New classes have been designed to allow multiple signal
	sources, signal controls, and signal sinks for I/O pins. These new
	objects can be added at will and thus allow the exact behavior of
	an I/O pin be tailored to a specific processor (and even changed
	dynamically). Thus a base class in the processor heirarchy can
	instantiate a register object, and the derived processors populate
	it with custom functionality.

	* cli/cmd_break.cc: documentation clean up
	* modules/usart.cc, modules/usart.h: tinkering - 
	* regression/logic_test/Makefile,
	regression/logic_test/logic_test.asm: Incorporates an un-released
	gpasm feature of the .direct macro. This feature allows multiple
	strings to be passed to gpasm.
	* regression/p16f84/p16f84.asm: Bug fix in PORTB pullup test


2005-07-15 J.R. Heisey <jrheisey@sourceforge.com>
	* gui/gui_watch.cc, gui/gui_watch.h: Fixed problem with
	register symbol names not displaying in the Watch
	window. Introduced this	bug when I made the bit mask feature
	in register symbols.

	* gui/gui_regwin.cc:  Fixed problem with register symbol 
	names not displaying in the RAM window. Introduced this 
	bug when I made the bit mask feature in register symbols.

2005-07-11 J.R. Heisey <jrheisey@sourceforge.com>
	* src/breakpoints.cc, h, src/cmd_gpsim.h, src/symbol.cc,
	plat/win32/gpsim.def, gpsim/main.cc, cli/ui_gpsim.cc,
	cli/ui_gpsim.h: Made changes so that when hitting a
	break will display program and register address symbols. 

	* src/breakpoint.cc: Removed calls to eval_Expression()
	where it is not necessary. Enhanced the break on value
	action text to include symbols and bit mask value.

	* cli/ui_gpsim.cc,h, gpsim/main.cc: Added functions that
	help display program and register address symbols along
	with the address value.

	* src/trigger.cc: Fixed problem in TriggerObject::
	eval_Expression() that was preventing non-expression
	based break points to not fire.

	* src/symbol.cc: Added check in Symbol_Table::
	findRegisterSymbol() to get register bit mask defined
	for the CPU when the passed in value is zero.


2005-07-10 J.R. Heisey <jrheisey@sourceforge.com>
	* plat/win32/gpsim.def, src/symbol.cc, src/symbol.h:
	Change function name from findRegister() to findRegisterSymbol()
	to reflect the return type. Added new findRegisterSymbol()
	version that takes a single address parameter. Did some
	minor code optimization of the findRegister() function.
	Due to the introductions of register symbol bit mask, I
	modified findRegister() to only return symbols that are
	defined for all bits of the register.

	* src/processor.cc: Changed some entry condition checks to
	allow processor::disassemble to disassemble one program
	address. Also made some minor code optimizations.

2005-07-06 Borut Razem <borut.razem@siol.net>
	* src/breakpoints.cc, src/gpsim_time.cc, src/interface.cc, src/processor.src, src/trace.cc:
	  declare dummy_bp, dummy_cycles, dummy_gi, dummy_get_active_cpu, dummy_set_active_cpu
	  and dummy_trace as non static to compile with gcc 3.4.4
	* plat/win32/gpsim.nsi: corrected version number to 0.21.8
	* gpsim/gpsim.vcproj, gpsim/makefile.mingw: linking with libgtkextra-win32-2.1.lib
	* doc/gpsimWin32.html: linking with gtk+extra-2.1.1, glib-2.6.5,
	  gtk+-2.6.8, pango-1.8.0, 1.9.0, fontconfig-2.2.2-20040412
	* plat/win32/make.mingw: change gcc command line options mcpu with mtune
	  to compile with gcc 3.4.4

2005-07-08 J.R. Heisey <jrheisey@sourceforge.com>
	* plat/win32/gpsim.def, src/symbol.cc, src/symbol.h:
	Added version of Symbol_Table::findRegister() that takes a bitmask
	parameter. Added Symbol_Table::findConstant() for future use.
	Need to implement a symbol to referenced from address
	cross reference.

	* gui/gui_src_opcode.cc, src/processor.cc: Fixed issues
	accessing program memory arrays using address instead
	of an appropriate index.

	* gui/gui_src_opcode.cc, src/processor.cc: Fixed issues
	with Processor::disassemble() function not traversing
	over break points to find the base instruction object.


2005-07-07 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_break.cc, cli/cmd_break.h: Code to display
	address labels in break related messages.

	* plat/win32/gpsim.def, src/pic-instructions.cc,
	src/pic-instructions.h,	src/processor.cc, src/processor.h,
	src/symbol.cc: Code to display address labels in a
	disassembly output. Added members to Processor class to
	support a page mask and offset mask that can be used to
	calculate absolute addresses for disassembly output for
	JUMP and CALL instructions. See the functions
	CalcJumpAbsoluteAddress() and CalcCallAbsoluteAddress();

2005-07-06 J.R. Heisey <jrheisey@sourceforge.com>
	* src/stimuli.cc, src/symbol.cc, src/symbol.h:
	Fixed a problem where renamed stimulus_symbol objects
	were getting lost. This caused a error when running
	the regression test digital_stim.

2005-07-06 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.nsi: NSIS 2.07 compatible

2005-07-05 J.R. Heisey <jrheisey@sourceforge.com>
	* src/symbol.cc, h: The access to a derived object's name()
	function was broken when I made the name() function in the
	base class const. I've propogated the const attribute to
	overriden versions of name().
	- Somewhere along this process on of my program variables stopped
	being added to the symbol table. So, I've changed the if statement
	that determines when a duplicate variable exists in the symbol
	table.
	- I've added a function called findProgramAddressLabel() so
	that a label name can be displayed where appropriate.

	* src/breakpoints.cc: Changed ::print() functions to output
	program memory labels where they could. Changed implementation
	to use the Console object rather than cout.

	* src/registers.cc: InvalidRegiser() constructor was not setting
	its address member variable. Now the address is included in the
	console warning.

	* src/attributes.cc: WarnModeAttribute() was not setting its
	value member variable.
	-  init_attributes() added some constant attributes for reset types.

2005-07-01 Scott Dattalo <scott@dattalo.com>
	* cli/scan.ll, cli/parse.yy, cli/input.cc: The recently added
	command line error processing change did not compile under Linux
	and was free a constant pointer.
	* gui/gui_main.cc, gpsim/main.cc: The command line prompt was
	always selected.

2005-07-01 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/scan.ll, cli/parse.yy, cli/input.cc,h:
	- Full command line text is displayed when a command line error
	occures.
	- Command line buffers are cleared appropriately after a command
	line error.

2005-06-30 Scott Dattalo <scott@dattalo.com>
	* regression/logic_test/logic_test.asm,
	regression/logic_test/Makefile, regression/logic_test/16f873.lkr:
	Added a regression test for gpsim Logic Modules.

2005-06-30 J.R. Heisey <jrheisey@sourceforge.com>
	* src/breakpoints.cc, src/breakpoints.h, cli/cmd_break.cc:
	New break point dump filtering.
	break r dumps register read break points.
	break w dumps register write break points.
	break e dumps execution break points.

	* cli/cmd_disasm.cc: Updated disassemble command on line help
	to reflect reality.

2005-06-30 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc, gpsim/main.cc, gui/gui_main.cc,
	src/gpsim_interface.h, src/interface.cc, src/modules.cc,
	src/modules.h, src/processor.cc:
	Added methods to the gpsim_interface class that manage the state
	of gui. This is done so that gui-based modules can query the gui
	state and conditionally build their graphical portions. 
	* modules/led.cc, modules/logic.cc:
	The Logic and LED modules now will not build any graphics if the
	gui is not initialized.
	Pin names were getting added to the symbol twice.

2005-06-27 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.cc, src/stimuli.h:
	Added putState()/getState() methods and removed putDrivingState
	method from the stimulus class. The purpose of this is to abstract
	away whether a node is driving or not. The main affect is in the
	gui breadboard where the state of I/O pins is queried.
	* gui/gui_breadboard.cc, gui/gui_breadboard.h, modules/usart.cc,
	modules/video.cc, modules/video.h, src/14bit-tmrs.cc,
	src/i2c-ee.cc, src/ssp.cc, 
	src/uart.cc: Updated calls to new stimulus class API.
	* modules/logic.cc, modules/logic.h: The logic gate modules had
	bit rotted. 

2005-06-26 J.R. Heisey <jrheisey@sourceforge.com>
	* plat/win32/gpsim.def, src/processor.cc, src/processor.h:
	New function Processor::init_program_memory_at_index() to
	continue the separation of PM address from PM array index.

2005-06-26 Scott Dattalo <scott@dattalo.com>
	* src/trace.cc: The wrong variable was being used to index the
	program counter array. This caused the trace to get an invalid
	instruction.

2005-06-26 Scott Dattalo <scott@dattalo.com>
	* INSTALL: Added notes from Bas Wijnen regarding Debian.

2005-06-25 Scott Dattalo <scott@dattalo.com>
	* src/symbol.cc, regression/simulate: The new 'BITS' indicator for
	register symbol queries broke the regression test. Now, the BITS
	indicator is only displayed if only a portion of the register
	applies to a register symbol. 

2005-06-24 J.R. Heisey <jrheisey@sourceforge.com>
	* src/modules.cc: Fixed a bug in Module::get() where
	a derive class does not override this function, now
	this function will return a null string.
	This fixes problems when a derived class is being
	displayed in the GUI symbol window causing a UTF-8
	warning.
	* src/symbol.cc: Fixed an introduced null pointer
	exception.

2005-06-23 J.R. Heisey <jrheisey@sourceforge.com>
	* plat/win32/gpsim.def, src/symbol.cc, src/symbol.h:
	register_symbol::m_uMask is used to mask out bits not
	associated with the symbol after retrieving the value
	from the register. Masked bit values are right shifted such
	that if the 16th bit is high in the register and
	m_uMask = 0x80, then the symbol value returned	
	or displayed will be one.	
	Likewise to set the 16th bit of our example register_symbol 
	you would set the register_symbol value to 0x01 and
	not 0x80. No other bits in the register are changed.
	It works as if this symbol is its own register. The encoding
	into the target register is hidden by register_symbol.
	The default value of m_uMask is 0xff so that no bits are
	masked out.
	An new version of Symbol_Table::add_register() may be used
	to add masked register_symbol objects to the symbol table.
	register_symbol::copy() is changed to return the correct
	symbol string.

2005-06-21 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_run.cc: Added help text saying that CTRL->C
	will stop a running simulation.

	* src/breakpoints.cc, src/processor.cc, src/processor.h,
	src/trace.cc, plat/win32/gpsim.def, gui/gui_profile.cc,
	gui/gui_src_asm.cc:
	There was significant ambiguity for some functions
	that appear to accept an simulation address but acted upon
	it as a ProgramMemoryAccess index. The ProgramMemoryAccess 
	indexing operator was a prime example. I have eliminated
	the indexing operator and added the functions getFromAddress()
	and getFromIndex() to make things more explicitly clear.
	I have also removed put() and get() and added putToAddress()
	and putToIndex(). Other new functions are
	hasValid_opcode_at_address() and hasValid_opcode_at_index().
	This mostly effected gui code so the simulation itself
	should have no impact.
	The original intent of this change was to fix bugs in the 
	gui where double clicking on a breakpoint icon in the
	source window would not toggle the breakpoint.

2005-06-17 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_dump.cc: dump register for special registers 
	broken when pReg->isa() and Register::SFR_REGISTER were 
	not being used. Now we dump the registers listed in 
	MemoryAccess::SpecialRegisters.

	* cli/input.cc: Implemented the	ability to break running 
	firmware using Ctrl->C key when running under Windows.
	It would previously exit gpsim.

	* gpsim/main.cc: Changed logic so the -i on the gpsim
	command line will not attempt to start the gui interface.
	
	* cli/cmd_break.cc, cli/cmd_clear.cc, cli/cmd_disasm.cc,
	cli/cmd_dump.cc, cli/cmd_frequency.cc, cli/cmd_help.cc,
	cli/cmd_load.cc, cli/cmd_module.cc, cli/cmd_processor.cc,
	cli/cmd_step.cc, cli/cmd_stimulus.cc, cli/cmd_trace.cc,
	cli/cmd_version.cc, cli/command.cc, cli/command.h:
	Implemented command abbreviations. Made abbreviations for
	several often used commands.

2005-06-14 J.R. Heisey <jrheisey@sourceforge.com>
	gui/gui_src.h, gui/gui_src_asm.cc, gui/gui_statusbar.cc,
	src/processor.cc, src/processor.h, src/registers.h:
	Fixed some problems with the source window optimization.
	Fixed problem with the text search dialog not searching
	alternate source windows.
	Fixed problem with Set PC Here from an alternate window.

2005-06-13 J.R. Heisey <jrheisey@sourceforge.com>
	*src/cmd_manager.cc, src/cmd_manager.h, src/modules.cc,
	cli/cmd_shell.cc: Fixed introduced bug where the command
	line interface from a library module was not accessible.
	A ! bang character alone lists the command line interfaces.

2005-06-13 Scott Dattalo <scott@dattalo.com>
	* configure.ac: Fixed recently introduced typo.
	* src/attributes.cc: Cycle counter attribute now prints correctly again.
	* src/processor.cc, src/processor.h: fixed bug in
	IsAddressInRange()  method, also reversed return value to match
	meaning of name (now returns true if the address is in range). 
	* src/symbol.cc: Symbol table dump was not showing symbol values.
	* src/registers.cc: fixed warning message for when invalid
	registers are accessed.

2005-06-10 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.cc, src/stimuli.h, src/symbol.cc, src/symbol.h:
	Stimuli symbols were not getting added to the symbol table when
	their name was being changed.

2005-06-10 J.R. Heisey <jrheisey@sourceforge.com>
	*src/gpsim_object.cc,h: Small change to allow name() call
	in a const variable context.

	*plat/win32/gpsim.def, src/processor.cc, src/stimuli.cc,
	src/symbol.cc, src/symbol.h, gui/gui_profile.cc: Changed
	the implementation of the Symbol_Table class to order
	by symbol name so that a binary search will improve lookup
	speed.

2005-06-10 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_stimulus.cc, doc/gpsim.lyx: Updated documentation.

2005-06-09 J.R. Heisey <jrheisey@sourceforge.com>
	*cli/cmd_module.cc: Added extra help for module command.

	*gui/gui_src.h, gui/gui_src_asm.cc, plat/win32/gpsim.def,
	src/processor.cc,h: Changed the parsing of the source for
	formatted display to speed things up during file loading.
	Source is now cached in a form for rendering to the formatted
	text window.

2005-06-09 Scott Dattalo <scott@dattalo.com>
	* gui/gui_main.cc, gui/gui_regwin.cc, gui/gui_src.cc,
	gui/gui_src_asm.cc, gui/gui_src_opcode.cc, configure.ac:
	Found the source of a bug that causes gpsim to hang when gtk-2.6.7
	and gtkextra-2.0 are used. The problem is either with gtkextra or
	the interaction of it with gtk. gpsim currently has in place a
	stop-gap measure to prevent the problem from keeping the simulator
	from being unusable.

2005-06-06 J.R. Heisey <jrheisey@sourceforge.com>
	*src/os_dependent.cc: The environment variable GPSIMPATH may be
	used to specify folders where shared libraries may be found. This
	is primarily for windows developers of gpsim.
	- Small change to prevent load_library() from displaying an error
	message that is not needed.

	*cli/cmd_node.cc: Use a reference instead of allocating a string
	on the local stack.

	*modules/modules.vcproj: Changed Visual Studio build of modules
	to libgpsim_modules.dll


2005-06-04 Scott Dattalo <scott@dattalo.com>
	* gui/gui.h, gui/gui_menu.cc, gui/gui_object.cc, gui/gui_object.h,
	gui/gui_src_asm.cc, gui/gui_statusbar.cc, gui/gui_statusbar.h:
	-- removed the cycle counter and time view from the status bar of
	the register and source windows and moved them to the window that
	contains the buttons.
	-- fixed text-width bugs in the status window.
	-- rewrote the implementation of the gui update code.
	-- Created a 'TimeWidget' class and a 'TimeFormatter' class for
	displaying the cycle counter object.
	-- Added a MainWindow class (kind of empty now).
	-- Re-introduced a few of the GTKWAIT macros.

2005-06-04 Scott Dattalo <scott@dattalo.com>
	* configure.ac, gpsim/Makefile.am: remove the explicit checks for
	the pthread library. 
	
2005-06-04 Scott Dattalo <scott@dattalo.com>
	* gpsim/main.cc: Allow filenames whose first character is a
	number.

2005-06-04 Scott Dattalo <scott@dattalo.com>
	Patch from: Rob Pearce <rob@bdt-home.demon.co.uk>
	* src/cod.cc: Fixed gramatical error.
	* src/eeprom.cc, src/eeprom.h: Added a new state to the eeprom
	state machine to fix ??
	* src/ioports.cc: fix to the 628 porta comparator.
	
2005-06-03 Scott Dattalo <scott@dattalo.com>
	* gui/gui_main.cc: Added a call to g_main_iteration() to allow GTK
	events to get processed. (This replaces the GTKWAIT macro that was
	removed in the previous commit).

2005-06-02 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc, gui/gui_main.cc: Removed GTKWAIT
	macros. Apparently on newer versions of GTK these macros block
	indefinitely. On really old versions of GTK (pre 2.0) these macros
	were necessary.

2005-05-26 J.R. Heisey <jrheisey@sourceforge.com>
	* src/breakpoints.cc,h, plat/win32/gpsim.def: added
	register assertions functionality. Can now assert the
	register value with !=, <=, >=, <, and > operators.

2005-06-01 Scott Dattalo <scott@dattalo.com>
	* src/os_dependent.cc: Printed an error message if
	a shared library fails to open.

2005-05-26 J.R. Heisey <jrheisey@sourceforge.com>
	* src/program_files.cc: Fixed crashing bug when no file
	types are able to open a program file.

2005-05-25 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.nsi, extras/lcd/makefile.mingw:
	added missing files to the WIN32 installation package in
	order to be able to compile the LCD modue; make LCD module
	mingw makefile a litle bit more flexible

2005-05-24 Scott Dattalo <scott@dattalo.com>
	* src/cod.cc, src/breakpoints.cc, src/trigger.cc,
	regression/assertions/assertions.asm: Added support
	for scripts embedded in .cod files.

2005-05-24 Scott Dattalo <scott@dattalo.com>
	* src/modules.h, src/modules.cc, src/processor.cc,
	src/breakpoints.cc, src/pic-processor.cc, src/hexutils.cc,
	gui/gui_src.cc, gui/gui_src_asm.cc, cli/scan.ll,
	src/cmd_manager.h, cli/cmd_dump.cc:
	
	-- renamed the enum's for the SIMULATION_MODE(s) (the
	enum 'INITIAL' collides with a macro in flex)
	-- added support for module scripts
	-- If a symbol begins with a period, then the scanner
	will automatically prepend the active processor name.
	(This is a short cut for accessing processor attributes).

2005-05-24 Borut Razem <borut.razem@siol.net>
	* doc/gpsimWin32.html, gpsim/gpsim.vcproj, gpsim/makefile.mingw:
	WIN32 with official release of gtk+extra-2.0.0

2005-05-22 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_break.cc, cli/cmd_break.h, cli/parse.yy, cli/scan.ll,
	src/breakpoints.cc, src/breakpoints.h, src/operator.cc,
	src/trigger.cc, src/trigger.h, src/value.cc:
	Added the capability of associating user defined messages with
	break points.
	Break point expressions (if present) are now displayed when the
	break points are displayed.
	* regression/assertions/Makefile,
	regression/assertions/assertions.asm: Use the coff.inc include
	file supplied with gputils and specifically the macros for
	assertions. 

2005-05-21 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_break.h, cli/cmd_break.cc, cli/input.cc, cli/parse.yy,
	src/cod.cc, src/breakpoints.cc: Execution breakpoints were failing
	to propogate execute() if an attached expression evaluated false.
	Added support for gpasm style assertions.
	* cli/scan.ll: Shell command escape character ('!') was
	conflicting with the not operator.
	* regression/assertions/assertions.asm,
	regression/assertions/Makefile, regression/assertions/16f873.lkr:
	Added a regression test for gpasm assertions.

2005-05-20 Scott Dattalo <scott@dattalo.com>
	* cli/scan.ll, regression/run_regression.sh,
	regression/macro_test/macro_test.stc:  Macros can now be nested.

2005-05-20 Scott Dattalo <scott@dattalo.com>
	* gui/gui_profile.cc: ifdef'd out code that a) is seldom (never?)
	used and b) incompatible with the latest official release of
	gtkextra. 
	
2005-05-19 Scott Dattalo <scott@dattalo.com>
	* src/ttoken.h, src/ttoken.cc, src/bytelog.cc, src/bytelog.h,
	src/pthread-wrap.h: Create a gpsim namespace and place the objects
	in these files in there.
	* cli/scan.ll: removed some printf debugging junk.

2005-05-19 Scott Dattalo <scott@dattalo.com>
	* cli/scan.ll, cli/cmd_macro.cc, cli/parse.yy, cli/input.cc:
	A recent change in string processing broke macros. Also, began
	adding code to support nested macros.
	* regression/macro_test/macro_test.asm,
	regression/macro_test/macro_test.stc: Added new regression test
	for macros.
	
2005-05-18 Scott Dattalo <scott@dattalo.com>
	* cli/scan.ll: Fixed end-of-line scan bug introduced on 5-16.

2005-05-16 J.R. Heisey <jrheisey@sourceforge.com>
	* src/os_dependent.cc: Added debug code to allow alternate
	directory paths for module libraries so I can specify debug
	build locations for shared libraries.
	* src/program_files.cc: Fixed bug caused by symbol table not
	being cleared when Program files are loaded.
	* src/modules.cc: Fixed bug when a module library failed to 
	load it was still being added to the installed library list.
	* configure.ac: bumped build number to 0.21.5

2005-05-16 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc, cli/scan.h, cli/scan.ll, cli/input.cc: command
	assertions where causing parse errors.

2005-05-14 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_processor.cc: The processor command wasn't working
	because of a typo in an if statement.
	* cli/parse.yy, cli/cmd_break.cc, cli/cmd_break.h: Added 'break
	#number' to allow inspection of an individual break point. Clean
	up some memory 	management.
	* src/breakpoints.cc: 'dump1()' wasn't checking to see if the
	break point number was valid.
	* src/os_dependent.cc: non-windows file extension comparisons were
	not working.
	* src/pic-processor.cc, src/symbol.h, src/symbol.cc, src/value.cc:
	val_symbols like the PIC program counter can now be parts of gpsim
	expressions.
	* src/cod.cc: hack - line number offset errof.
	* doc/gpsim.lyx: Updated the documentation.

2005-05-12 Scott Dattalo <scott@dattalo.com>
	* gui/gui_regwin.cc, gui/gui_src_opcode.cc, gui/gui_src_asm.cc:
	Removed calls to GTKWAIT because they sometimes block in the newer
	version (2.6.7) of GTK. Thanks to Micah Carrick for pin-pointing
	this one.
	
2005-05-11 Scott Dattalo <scott@dattalo.com>
	* src/sim_context.cc: The included file "direct.h" does not exist
	on FC3.

2005-05-10 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_load.cc: Updated on line help for load command.
	* gui/gui_src_asm.cc: Removed a call to gtk_widget_destory()
	in SourcePage::Close() where it was causing a crash in Windows.
	* cli/scan.ll: Defined literal string values to be quoted. This
	was done so that quoted Windows paths in the load command to 
	accommodate colons for drive designation and backslashes for
	folder delimiters.
	* gpsim/main.cc: Added the gpsim.exe startup folder to the
	module/library search path.
	* src/sim_context.cc, src/errors.h: Added an error message to CSimulationContext::
	LoadProgram().
	* cli/cmd_module.cc, src/modules.cc, src/modules.h,
	src/os_dependent.cc, gpsim/main.cc: Added code to not load
	a module library that is already loaded.

2005-05-06 J.R. Heisey <jrheisey@sourceforge.com>
	* gui/gui_regwin.cc:  Fixed crash that occurs when RAM register
	count is not a multiple of 16.
	* plat/win32/gpsim.def: Added new function reference.
	* src/processor.cc:  Fixed broken list command
	* src/sim_context.cc: Fixed broken register output on stepping
	that broken on previous check in. Test for open file failure.
	* src/program_files.h: Add new error code.

2005-05-05 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_break.cc, cli/cmd_disasm.cc, cli/cmd_dump.cc,
	cli/cmd_frequency.cc, cli/cmd_list.cc, cli/cmd_load.cc,
	cli/cmd_load.h, cli/cmd_log.cc, cli/cmd_processor.cc,
	cli/cmd_reset.cc, cli/cmd_step.cc, cli/cmd_x.cc, cli/command.cc,
	cli/command.h, cli/input.cc, cli/input.h, cli/parse.yy,
	src/cod.cc, src/cod.h, src/hexutils.cc, src/Makefile.am,
	src/modules.h, src/os_dependent.cc, src/pic-processor.cc,
	src/pic-processor.h, src/processor.cc, src/processor.h,
	src/program_files.cc, src/program_files.h, src/sim_context.cc,
	src/sim_context.h, src/src.vcproj, src/symbol.cc, src/symbol.h,
	config_win32.h.in, configure.ac, plat/win32/gpsim.def,
	gui/gui_menu.cc, gui/gui_src_asm.cc, gui/gui_statusbar.cc,
	gpsim/Makefile.am:
	- Replaced the cli and gui references to hexfiles verses
	cod file with program files. Gpsim will now figure out
	the file type and load the file.
	- Both the gui and cli will recoginze command files by the stc
	file extension. All other files are assumed to be program files.
	- The c, h and s load options of the load command will be accepted
	for backwards compatibility of existing command files but are no
	longer needed.
	- The processor command is not optional. If the program file
	contains the information about the processor type, gpsim will
	allocate the processor type based on the program file information.
	Using the processor command overrides this behavior.

2005-05-01 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def: MSVC sync

2005-04-29 Scott Dattalo <scott@dattalo.com>
	* HISTORY, README, INSTALL, configure.ac, gpsim.spec.in: Updates
	for the 0.21.4 
	* extras/lcd/ChangeLog, Makefile.am, configure.in: bumped the Rev
	of the LCD module to 0.2.4

2005-04-29 Scott Dattalo <scott@dattalo.com>
	* src/breakpoints.cc: Register assertions were not halting
	simulation when assertion was true.
	
2005-04-26 Scott Dattalo <scott@dattalo.com>
	* cli/Makefile.am, examples/14bit/Makefile.am: Updated so that
	'make dist' would work again.
	* src/attributes.cc, src/init.cc: Moved attribute initialization
	from init.cc to attributes.cc 
	* src/breakpoints.cc, src/symbol.cc, src/symbol.h, src/trigger.cc:
	Complex expressions are now fully supported. Updated the help info
	for the break command to reflect the new syntax (more work
	needed).
	
2005-04-26 Scott Dattalo <scott@dattalo.com>
	* src/breakpoints.cc, src/breakpoints.h, cli/parse.yy,
	cli/cmd_break.cc, cli/cmd_break.h: continuing with complex break
	expressions. 

2005-04-25 Scott Dattalo <scott@dattalo.com>
	* src/trigger.h, src/trigger.cc, src/breakpoints.cc: Added complex 
	expressions to the TriggerObject class. (not complete)

2005-04-23 Borut Razem <borut.razem@siol.net>
	* src/bitlog.cc, src/bytelog.cc, src/ttoken.cc: removed #define IN_MODULE
	* plat/win32/gpsim.def, modules/makefile.mingw, src/makefile.mingw,
	modules/modules.vcproj, src/src.vcproj: MINGW sync
	* gpsim/makefile.mingw: force linker to onclude BoolEventLogger class
	methods in gpsim.exe, so that they can be referenced by modules
	* src/modules.cc (get_attribute): fixed attribute name comparison
	* src/sim_context.h: added end of line at end of file
	* plat/win32/gpsim.nsi: remove pthreadVC1.dll

2005-04-22 Scott Dattalo <scott@dattalo.com>
	* bitlog.cc, bitlog.h, bytelog.cc, bytelog.h, ttoken.cc, ttoken.h,
	pthread-wrap.h: moved these from the modules/ directory into the
	src/ directory.

2005-04-19 J.R. Heisey <jrheisey@sourceforge.com>
	* src/breakpoints.cc, src/processor.cc, src/processor.h:
	Fixed corruption when clearing a Breakpoint_Instruction object.
	The object was not removed properly from the chain of instruction
	objects in the pma.

2005-04-19 Scott Dattalo <scott@dattalo.com>
	* src/os_dependent.cc: Added 'errno.h' to the list of include
	files. (without this, os_dependent.cc wouldn't compile on
	FC3-64bit). 

2005-04-19 Scott Dattalo <scott@dattalo.com>
	* src/symbol.cc, src/symbol.h: Fixed reference to symbol table
	that was preventing compilation on Linux.

2005-04-19 J.R. Heisey <jrheisey@sourceforge.com>
	*  gui/gui_src_asm.cc, gui/gui_statusbar.cc, gui/gui_statusbar.h:
	Modified the statusbar so that it can handle a switch from
	one processor to another.
	* src/sim_context.cc, src/symbol.cc,h: Fixed a crash on gpsim
	exit.
	* src/os_dependent.c: added test in load_library() to the first
	call to sLoad() to determine whether the a failure was due
	to the library file not found or some other error. This needs
	to be completed for the linux builds.

2005-04-18 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.cc: Stimulus_Node destructor now removes itself from
	the symbol table.

2005-04-17 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.h, src/stimuli.cc: Added methods to control the
	resistance and voltage of the IO_bi_directional_pu pullup resistor.

2005-04-16 Scott Dattalo <scott@dattalo.com>
	* src/symbol.cc: set methods for register symbol now initialize
	the "init" field in the register object.

2005-04-16 J.R. Heisey <jrheisey@sourceforge.com>
	* src/value.cc,h, src/symbol.cc,h, src/processor.cc,h,
	src/pic-processor.cc,h, makefile.mingw, Makefile.am,
	cli/input.cc, cli/init.cc, gui/gui_symbols.cc, gui/gui_stack.cc,
	gui/gui_src_asm.cc, gui/gui_profile.cc, src/gpsim_time.cc,
	plat/win32/gpsim.def, src/cod.cc, cli/cmd_processor.cc,
	added src/sim_context.cc.h: Restructured classes in preparation
	for allowing a simulation context to be reset for a new processor
	with out having to close the program and with out memory leaks.
	The new class CSimulationContext, implemented as a singleton for
	now, owns a CProcessorList. The singelton class
	ProcessorContructorList is used to create processor objects.
	Eventually CSimulationContext may own Breakpoints, Symbol_Table
	and the active_cpu objects. For now. there are accessor functions
	to get to the global objects. CSimulationContext.set_processor()
	will check for a matching processor in the processor list before
	allocating a new processor.
	Processor related classes now delete the objects that they own
	on destruction. May not be conprehensive. set_processor() currently
	deletes a matching processor object rather than reinitializing it
	for a new simulation session.

2005-04-15 Scott Dattalo <scott@dattalo.com>
	* cli/command.h, cli/input.cc, cli/parse.yy, cli/scan.ll,
	gpsim/main.cc: Finished support for reentrant parsing.
	* cli/cmd_disasm.cc: Cleaned up a buglet in printing.
	* src/attributes.cc, src/attributes.h, src/pic-processor.cc,
	src/processor.cc, src/processor.h: Added an attribute that
	controls the behavior of simulator when a reset is encountered. 

2005-04-15 Scott Dattalo <scott@dattalo.com>
	* src/cod.cc, cli/cmd_run.cc, cli/cmd_run.h, cli/input.cc,
	cli/input.h, cli/parse.yy, cli/scan.ll:
	Added initial support for .COD file assertions.
	  -- Parser is now reentrant
	  -- gpsim's CLI interface is now a registered interface
	     that can be referenced and accessed by the simulation
	     engine.
	* src/ioports.cc: experimental tinkering

2005-04-14 Scott Dattalo <scott@dattalo.com>
	* build.xml: configure was not getting invoked.

2005-04-14 Scott Dattalo <scott@dattalo.com>
	* build.xml: autoconf was not getting invoked...

2005-04-13 Scott Dattalo <scott@dattalo.com>
	* build.xml: An XML script for an experimental regression tool
	(based on the open source projects "ant" and "CruiseControl").

2005-04-09 Borut Razem <borut.razem@siol.net>
	* cli/makefile.mingw, src/makefile.mingw: MINGW sync

2005-04-08 J.R. Heisey <jrheisey@sourceforge.com>
	* src/breakpoints.cc, src/cmd_manager.cc,h, gpsim/main.cc,
	src/processor.cc,h, cli/ui_gpsim.cc,h, src/registers.cc,
	cli.vcproj, gpsim.vcproj, src.vcproj: Created a IUserInterface
	and CGpsimUserInterface as the implementation with functions to
	write predefined parameterized strings to the console (or in the
	future a GUI popup).
	Modules call the C function GetUserInterface() to retrieve an
	instance of CGpsimUserInterface as a IUserInterface.
	Using IUserInterface functions is the prefered way of writing error
	and notification messages to the gpsim console from other modules.

2005-04-08 Scott Dattalo <scott@dattalo.com>
	* cli/parse.yy, cli/cmd_break.h: Added support for a break command
	like: 
	    break r|w reg(N) 
	Where N is an integer and 'reg' is the new reg operator.

2005-04-08 Scott Dattalo <scott@dattalo.com>
	* cli/parse.yy, cli/scan.ll: Added a "reg()" operator that can cast
	integers into registers (although this is not fully implemented
	yet).
	A single quote before an identifier now acts as an 'escape'
	character. This allows user defined strings to collide with gpsim
	built in strings. (e.g. If a user has a variable named help, its
	contents can be examined by typing 'help at the command line).

2005-04-07 J.R. Heisey <jrheisey@sourceforge.com>
	src/breakpoints.cc: Fixed a memory leak by properly removing
	chained BreakpointRegister objects from the Register chain when
	clearing a break object. When the chain is properly maintained
	the object may be deleted.

2005-04-07 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/scan.ll, cli/parse.yy, cli/cmd_break.cc,h,
	src/processor.cc,h, src/pic-processor.cc, operator.cc,h,
	src/breakpoints.cc: Changed the break command syntax.
	Added code to support the syntax.

2005-04-07 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_manager.h, cli/cmd_manager.cc, cli/cmd_gpsim.h:
	moved from cli/ to src/
	* src/processor.cc, src/Makefile.am, src/interface.cc,
	src/processor.cc, gpsim/main.cc, cli/Makefile.am,
	cli/cmd_manager.cc, cli/cmd_module.cc, cli/cmd_shell.cc:
	Updated these files to use the newly relocated .h files. The reason
	for doing this is to fix a src/ dependency on cli/ files. When
	src/ depends on cli/ then any module that links against the gpsim
	library must also link against the cli library.
	* src/registers.cc: added a Bit class (currently not used though)
	* src/symbol.cc: attribute symbols that wrap other symbols now change
	the name of the wrapped symbol. This allows heirarchical names
	such as processor_name.attribute to appear in the symbol table.

2005-04-06 J.R. Heisey <jrheisey@sourceforge.com>
	* src/processor.cc.h: Two new break message functions.

2005-04-05 J.R. Heisey <jrheisey@sourceforge.com>
	* src/value.h, src/registers.cc,h, src/processor.cc.h,
	src/preakpoints.cc,h, plat/win32/gpsim.def: Implemented
	classes and functions for displaying the register address
	and possible value for break on read and break on write.

2005-04-05 J.R. Heisey <jrheisey@sourceforge.com>
	* gpsim/main.cc, src/interface.cc, src/gpsim_interface.h,
	cli/cmd_manager.h: Added code to support for an external module to
	access the global ISimConsole object from the Interface class.

2005-04-04 J.R. Heisey <jrheisey@sourceforge.com>
	* src/processor.cc,h: Added the function Processor::IsAddressInRange().
	Use IsAddressInRange() in ProgramMemoryAccess::get_src_line() and
	ProgramMemoryAccess::operator [](unsigned int address)

2005-04-02 Scott Dattalo <scott@dattalo.com>
	* src/processor.cpp: Reverted the change J.R. made on 2005-03-31
	because it breaks the gui for the 18F family of PICs. We'll need
	to come up with another way of solving the initial PC value
	problem.
	
2005-03-31 J.R. Heisey <jrheisey@sourceforge.com>
	* src/processor.cpp: Changed call ProgramCounter->get_PC() to
	ProgramCounter->get_value() to fix a problem where the initial
	position of the PC in the source was not getting set properly.
	Return value is used for indexing into source code line.
	Mostly used by the UI so should not affect behavior.

2005-03-30 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_dump.cc: Changed ram dump command to handle ram sizes
	greater than one byte.
	* cli/cmd_x.cc: Removed call to dump.dump(DUMP_SFRS) since previous
	call to dump.dump(DUMP_RAM) already dump thes sfrs too.ram halt.
	* Cleaned up a couple of GUI error messages. (invalid window handle,
	invalid value strings)

2005-03-24 J.R. Heisey <jrheisey@sourceforge.com>
	* src/breakpoints.cc, src/processor.cc, h, cli/cmd_clear.cc:
	Fixed crash in Breakpoints::clear() that I reintroduced in my last checkin.
	Also Fixed the original memory leak by properly removing chained 
	Breakpoint_Instruction objects from the instruction chain when clearing a
	break object. When the chain is properly maintained the object may be
	deleted. Perhaps this should be a temporary fix until a base class
	for Breakpoint_Instruction all have a replaced member.

2005-03-23 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc: changed the comment text color to 'dim gray'

2005-03-23 Scott Dattalo <scott@dattalo.com>
	* src/value.cc: Fixed write to a null pointer in String::get(char
	*buf, int len).
	* src/symbol.cc: Fixed infinite loop in 
	char *register_symbol::name (char *buf, int len).
	* regression/ccp/ccp.asm: added more features to the ccp
	regression test.
	
2005-03-22 J.R. Heisey <jrheisey@sourceforge.com>
	* gui/gui_watch.cc: Fixed problem with register values > 127 causing pango runtime warnings

2005-03-21 J.R. Heisey <jrheisey@sourceforge.com>
	* src/breakpoints.cc, src/processor.h: created a notification
	to Processor when breakpoints are set or cleared. Cleaned up
	code in breakpoints.cc.

2005-03-23 Scott Dattalo <scott@dattalo.com>
	* src/16bit-instructions.cc: The NEGF instruction for the 18f
	family was erroneously writing the negated result to W.
	* regression/instructions_16bit/instructions_16bit.asm: added a
	regression test for the NEGF instruction.

2005-03-21 J.R. Heisey <jrheisey@sourceforge.com>
	* src/processor.cc: Copy a null string to input parameter
	Processor::get(char *cP, int len) because not value is
	associate with a Processor object. Fixes trace errors from
	pango when the symbol window is scrolled to some symbol objects.
	* src/value.cc: Copy a null string to input parameter
	String::get(char *buf, int len) when not value string is
	allocated. Fixes trace errors from pango when symbol window
	is scrolled to some symbol objects.

2005-03-18 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_load.cc/h, src/cod.cc/h, cli/input.cc, cli/parse.yy:
	added error checking for opening cod, hex and stc files.
	Particularily when opened from the GUI.

2005-03-17 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.cc: tweaking of I/O thresholds.

2005-03-16 Scott Dattalo <scott@dattalo.com>
	* cli/scan.ll, src/stimuli.h, src/stimuli.cc, src/symbol.cc,
	src/symbol.h: Added/enhanced methods for searching, adding, and
	removing symbols and stimuli.

2005-03-14 J.R. Heisey <jrheisey@sourceforge.com>
	* src/modules.h, modules.cc, os_dependent.cc: Elimaticated
	undesired error message on failure to load a function of a
	module.
	Simplified Module_Library() constructor to use os independent
	api call get_library_export()

2005-03-14 Scott Dattalo <scott@dattalo.com>
	* plat/win32/gpsim.def: MSVC sync.
	* modules/modules.vcproj: Use new pthread library.
	* gui/gui_register.h, gui/gui_regwin.cc: pass registerValue by
	value in getValueAsString() method.

2005-03-03 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def: MSVC sync

2005-03-10 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.cc: Added an 'X' state to getBitChar method
	of the IO_open_collector class.

2005-03-09 Borut Razem <borut.razem@siol.net>
	* modules/makefile.mingw: pthreads upgrade

2005-03-08 Scott Dattalo <scott@dattalo.com>
	* src/value.cc, gui/gui_profile.cc, gui/gui_statusbar.cc,
	gui/gui_trace.cc: Corrected temporary hack regarding PRINTF_INT64_MODIFIER

2005-03-08 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.nsi: removed examples\14bit\*.inc
	* cli/cmd_manager.h: added newline at the end of file
	* doc/gpsimWin32.html: atk upgraded to 1.8.0

2005-03-08 Scott Dattalo <scott@dattalo.com>
	* regression/ccp/ccp.asm: improvements to ccp regression test
	* gui/gui_profile.cc, gui/gui_trace.cc, gui/gui_statusbar.cc,
	src/value.cc: Temporarily removed windows-specific macro.
	* src/stimulus.cc, src/stimuli.h: Cleaned up asynchronous stimuli
	* src/registers.h, src/ssp.cc, src/ioports.cc, src/14bit-tmrs.cc:
	Made the default register class access functions all go through
	one function to obtain a register's value.

2005-02-26 Scott Dattalo <scott@dattalo.com>
	* src/processor.h, src/trace.h, src/breakpoints.h, src/symbol.h,
	src/gpsim_interface.h, src/gpsim_time.h:
	The external references demarcated by 'IN_MODULE' were not getting
	resolved in FC3. Since these were introduced to resolve a linking
	problem with WIN32 DLL's, I made the demarcation dependent on only
	Windows. 

2005-02-25 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.h, src/stimuli.cc: Added methods to the IOPIN class
	to differentiate between a pin driving a node and one being driven
	by a node.
	* src/14bit-tmrs.cc, src/i2c-ee.cc, src/packages.cc, src/ssp.cc,
	src/stimuli.cc, src/stimuli.h, src/uart.cc, extras/lcd/lcd.cc,
	gui/gui_breadboard.cc, modules/logic.cc, modules/logic.h,
	modules/usart.cc, modules/video.cc, modules/video.h: Propogate
	IOPIN change to all consumers.

2005-02-24 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.h, src/stimuli.cc: Added impedance thresholds
	to differentiate strong, weak, and floating drivers.

2005-02-16 Scott Dattalo <scott@dattalo.com>
	* src/ioports.cc: experiments in ioport redesign.

2005-02-16 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.h, src/stimuli.cc: Added 'getBitChar()' method to
	the open collector stimulus class.

2005-02-15 Scott Dattalo <scott@dattalo.com>
	* src/ioports.cc, src/ioports.h: Added a 'getIO' method to the
	IOPIN class that will allow an individual I/O pin in a port to be
	accessed.
	* src/stimuli.h, src/stimuli.cc: Add more state information to the
	snode class. Also, added the 'getBitChar()' method that will
	return the state of the stimulus in the form of an ASCII character
	(e.g. 0,1,Z,W).

2005-02-11 Scott Dattalo <scott@dattalo.com>
	* src/os_dependent.cc: Libraries stored in system directories were
	getting ignored.

2005-02-09 Scott Dattalo <scott@dattalo.com>
	* src/Makefile.am: Newly added src file 'os_dependent.cc' was not
	part of the Makefile
	* cli/input.cc, src/os_dependent.cc: abstracted some os dependent
	changes that were recently added

2005-02-01 Scott Dattalo <scott@dattalo.com>
	* src/processor.h, src/processor.cc, src/trace.cc: Added 'Debug()'
	method to processor class and call it whenever a register
	assertion occur.s

2005-01-30 Borut Razem <borut.razem@siol.net>
	* config_win32.h.in, configure_win32.awk: extract version, package and
	  bugreport values from configure.ac

2005-01-26 Scott Dattalo <scott@dattalo.com>
	* configure.ac: repositioned the call to the m4 macro wi_READLINE_LIB
	so that it would run properly.

2005-01-26 Scott Dattalo <scott@dattalo.com>
	* plat/win32/gpsim.def: added more external cross references.
	* module/modules.vcproj: changed from pthreadVC1.lib to
	pthreadVC.lib.

2005-01-23 Scott Dattalo <scott@dattalo.com>
	* configure.ac: Craig Franklin updated gpsim's configure files. It
	turns out there was a tiny bug preventing things to build a
	*second* time (the first time would work fine)
	* src/gpsim_time.h, src/gpsim_time.cc, src/init.cc: The newly
	added and globally instantiated StopWatch class' constructor was
	making calls to the globally instantiated (but not necessarily
	constructed) Symbol_Table class. Now, StopWatch::init() will make
	the calls to the symbol table.

2005-01-21 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def, src/src.vcproj: MSVC sync
	* doc/gpsimWin32.html: gpsim works with flex 2.4.31

2005-01-20 Scott Dattalo <scott@dattalo.com>
	* src/breakpoints.cc: Trigger actions were not printing
	execution breakpoint messages.
	* src/registers.h, src/registers.cc: Added a skip_start function to
	the program counter.

2005-01-19 Scott Dattalo <scott@dattalo.com>
	* src/registers.cc, src/registers.h, src/gpsim_object.cc,
	  src/gpsim_object.h, src/symbol.cc, src/symbol.h,
	  src/value.cc, src/value.h: Added the 'toBitStr' method
	to gpsim_object and propopogated the change through the
	derived classes. Also, the register class now calls get() to 
	obtain the value printed with toString and toBitStr instead
	of directly using its value object.

2005-01-17 Scott Dattalo <scott@dattalo.com>
	* src/gpsim_time.h, src/gpsim_time.cc: Finished the StopWatch
	class.
	* src/value.cc, src/value.h, src/attributes.cc, src/attributes.h:
	Added attribute breakpoints. For attributes that can be associated
	with breakpoints, you can now write 'break attribute' to set a
	breakpoint on that attribute.
	* cli/Makefile.am, cli/cmd_break.cc, cli/cmd_break.h,
	cli/cmd_help.cc, cli/command.cc, cli/parse.yy: The 'stopwatch'
	command is now handled by attributes. Added the following
	attributes:
	stopwatch, stopwatch.enable, stopwatch.direction,
	stopwatch.rollover.
	The 'stopwatch' attribute supports breakpoints, so the 'break
	stopwatch'  command will break whenever the stopwatch rolls over.

2005-01-15 Scott Dattalo <scott@dattalo.com>
	* src/attributes.cc, src/attributes.h: New files to support gpsim
	attributes.
	* src/Makefile.am, src/makefile.mingw: added the new files to the
	make files.

2005-01-14 Scott Dattalo <scott@dattalo.com>
	* gpsim/main.cc, gui/gui_main.cc: The gtk main loop is now started
	even if the command line option --cli is specified. This way, the
	GIOChannels will still operate.

2005-01-13 Scott Dattalo <scott@dattalo.com>
	* cli/sockect.cc, src/value.cc: Added support for 'Socket Sinks'
	and 'Socket Sources'. These essentially are two ways in which a
	client can choose to communicate with gpsim. 

2005-01-10 Scott Dattalo <scott@dattalo.com>
	* cli/sockect.cc, src/protocol.cc, src/protocol.h,
	src/symbol.cc, src/symbol.h, src/value.cc,src/value.h:
	Fixed bugs associated with socket notify links.

2005-01-09 Scott Dattalo <scott@dattalo.com>
	* src/ioports.cc: Began I/O port redesign.
	* cli/socket.cc, src/protocol.h: Added Socket callbacks.
	* examples/scripts/client3.cc, examples/scripts/makefile,
	examples/scripts/client_interface.cc,
	examples/scripts/client_interface.h: Added a new client script
	example illustrating socket callbacks.
	* gui/gui_main.cc: removed a printf debug statement.

2005-01-09 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def: MSVC sync
	* doc/gpsimWin32.html: dependedncy on gawk, ...
	* cli/cli.vcproj, cli/scan.ll: make it work with flex 2.4.31
	* plat/win32/gpsim.nsi, modules/makefile.mingw, modules/modules.vcproj:
	  pthreads 2005-01-03
	* gui/gui_menu.cc: use utf-8 encoded LATIN SMALL LETTER Z WITH CARON
	  instead LATIN SMALL LETTER Z.

2005-01-07 Scott Dattalo <scott@dattalo.com>
	* src/16bit-processors.cc: stop gap hack - added registers
	to hold the places of the analog SFR's
	* cli/socket.cc, src/protocol.h, src/value.cc, src/value.h:
	More socket improvements.

2005-01-05 Scott Dattalo <scott@dattalo.com>
	* src/breakpoints.cc, src/gpsim_classes.h, src/gpsim_interface.h,
	src/interface.cc, src/modules.cc, src/modules.h,
	src/pic-processor.cc, src/protocol.cc, src/protocol.h,
	cli/command.cc, cli/socket.cc:
	Enhancements to support the socket interface. Added a run command
	and a reset command and made them invocable via the interface class.

2005-01-02 Scott Dattalo <scott@dattalo.com>
	* gui/gui_main.cc, cli/input.cc, src/interface.cc: Added function
	'gUseThreads()' and use it to run-time select the usage of threads.

2005-01-02 Borut Razem <borut.razem@siol.net>
	* gui/gui_break.cc, gui/dialog.cc, gui/gui_init.cc, gui/gui_menu.cc,
	  gui/gui_processor.cc, gui/gui_src.cc, gui/gui_src_asm.cc
	  gui/gui_src_opcode.cc: removed unneeded include gtkcombobox.h
	* gui/gui_breadboard.cc: fixed compiler warnings
	* cli/Makefile.am, gui/Makefile.am: added AM_ preffix to CFLAGS,
	  CXXFLAGS, CPPFLAGS and YFLAGS
	* doc/gpsimWin32.html: gtk+ version 2.4.14, XHTML 1.0 Transitional compliant,
	  gtk+extra-2-1.1.0-20050102
	* doc/gpsim_cvs.html: changed first build instructions

2004-12-17 Scott Dattalo <scott@dattalo.com>
	* gui/gui_main.cc, src/interface.cc, cli/socket.cc: removed
	dependencies on GTK 2.0.

2004-12-19 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.nsi: added examples/scripts/client_interface.h
	  to installation
	* mingw/makefile.mingw, gpsim/gpsim.vcproj: added gthread-2.0.lib
	* src/src.vcproj: removed plat\win32\glist.cpp from project; CLI
	  mode now requires linking with full glib library; added src/trigger.cc
	  and src/trigger.h to the project
	* modules/modules.vcproj: pthreads to the project
	* gpsim.sln: removed building of modules in CLI configuration

2004-12-17 Scott Dattalo <scott@dattalo.com>
	* gui/gui_main.cc, src/interface.cc: replaced pthread_* calls and
	declarations with the corresponding GTK ones.

2004-12-17 Scott Dattalo <scott@dattalo.com>
	* gui/gui_main.cc, src/interface.cc: Added experimental code to
	test threading.

2004-12-16 Scott Dattalo <scott@dattalo.com>
	* gui/gui_main.cc, gui/gui_menu.cc: Use the interface instead of
	the cpu pointer to initiate simulation.
	* src/Makefile.am, src/trigger.cc, src/trigger.h,
	src/breakpoints.cc, src/breakpoints.h: Split the
	trigger classes away from the breakpoint classes.
	* src/gpsim_interface.h, src/init.cc, src/interface.cc,
	src/pic-processor.cc, src/protocol.cc, src/protocol.h,
	src/trace.h, cli/cmd_run.cc, cli/cmd_set.cc, cli/cmd_trace.cc,
	cli/input.cc, cli/socket.cc:
	Attempted (but failed) to add a feature that would allow a socket
	interface to send data to the simulator while a simulation is
	running. It turns out that the giochannel stuff used to control
	the socket runs in the gui event loop. The only time the socket is
	handled is whenever the loop can run. However, since gpsim is a
	single threaded application (the gui does spawn its own private
	thread), the gui event loop only runs whenever the simulation
	gives it cpu time. Thus it's not possible for a socket to update
	the simulation except when the gui is being refreshed!
	* examples/scripts/client.cc, examples/scripts/gensquares.asm,
	examples/scripts/makefile, examples/scripts/client2.cc,
	examples/scripts/client_interface.cc,
	examples/scripts/client_interface.h:
	Added a class to encapsulate the gpsim client socket
	interface. Added another example to test socket updates while the
	simulation is running.

2004-12-16 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def: MSVC sync
	* src/14bit-registers.h: declare void
	  Status_register::put(unsigned int new_value) as virtual, not inline
	* gui/gui_src_opcode.cc: removed definition of unused variable pm_size
	  in method SourceBrowserOpcode_Window::NewProcessor()
	* extras/lcd/makefile.mingw: added
	* plat/win32/gpsim.nsi: added additional files from examples\scripts to
	  the package
	* cli/input.cc: function have_line() is needed also in non GUI mode
	* gui/profile.cc, gui/gui_statusbar.cc, gui/gui_stopwatch.cc,
	  gui/gui_trace.cc, src/14bit-tmrs.cc, src/16bit-registers.cc,
	  src/eeprom.cc, src/i2c-ee.cc, src/interface.cc, src/interface.h,
	  src/ioports.cc, src/p16x7x.cc, src/pic-processor.cc,
	  src/pic-registers.cc, src/ssp.cc, src/stimuli.cc, src/tmr0.cc,
	  src/uart.cc: replace direct access to cycles with a getter
	  function get_cycles()

2004-12-15 Scott Dattalo <scott@dattalo.com>
	* src/init.cc, src/gpsim_time.cc:
	Delayed creation of the cycle counter attribute. It turns out that
	this attribute was created in the Cycle_Counter constructor which
	is called by the globally instantiated 'cycles' object. On
	Windows, this call happened before the symbol table was
	inititialized .

2004-12-14 Scott Dattalo <scott@dattalo.com>
	* src/init.cc: added new function for initialization. Also added
	new attribute 'sim.verbosity' that will control the simulator's
	verbosity. Note, this duplicates the behavior of the global
	variable 'verbose'. However, the goal is to phase out the global
	variable.
	* cli/cmd_run.cc: the run command now examines the new verbosity
	attribute.
	* src/pic-processor.cc, src/pic-processor.h, src/processor.cc,
	src/processor.h: the run member function now takes a parameter
	that controls whether or text will be printed.
	* cli/socket.cc:
	* src/interface.h: added extern def for new init function.
	* gpsim/main.cc: call new initialization function
	* src/breakpoints.cc: removed superfluous carriage return print.
	* examples/scripts/README, examples/scripts/client.cc,
	examples/scripts/makefile:  added  new files to illustrate
	scripting.
	* examples/scripts/gensquares.asm: minor tweak to simplify example
	regression test. 

2004-12-14 Scott Dattalo <scott@dattalo.com>
	* cli/scan.ll, cli/socket.cc, src/protocol.cc, src/protocol.h,
	src/value.cc: Fixed compilation issues with FC3 on an Athlon 64.

2004-12-11 Borut Razem <borut.razem@siol.net>
	* src/makefile.mingw, src/src.vcproj: added protocol.cc and protocol.h
	* plat/win32/gpsim.def: MSVC sync

2004-12-10 Scott Dattalo <scott@dattalo.com>
	* src/gpsim_time.cc: Added a "cycles" attribute for interfacing
	with the cycle counter class.
	* src/protocol.cc, src/protocol.h, src/symbol.cc, src/symbol.h,
	src/value.cc, src/value.h, cli/socket.cc: 
	More improvements to the protocol stuff.

2004-12-09 Scott Dattalo <scott@dattalo.com>
	* src/protocol.h, src/protocol.cc, src/Makefile.am: New files to
	support a communication protocol for gpsim.
	* cli/socket.cc: moved much of the protocol related stuff to the
	new files.
	* src/value.h, src/value.cc, src/symbol.h, src/symbol.cc: Symbols
	and Values can now be assigned by Packets.
	* src/12bit-instructions.h, src/12bit-processors.h,
	src/14bit-instructions.h, src/14bit-processors.h,
	src/14bit-tmrs.h, src/16bit-processors.h, src/16bit-tmrs.h,
	src/breakpoints.h, src/p12x.h, src/p16f62x.h, src/p16x5x.h,
	src/p16x6x.h, src/p16x8x.h, src/pic-instructions.h,
	src/pic-processor.h, src/processor.h, src/trace.h, src/xref.h:
	fixed typo in GPL disclaimer.

2004-12-07 Scott Dattalo <scott@dattalo.com>
	* cli/socket.cc: More socket clean up
	* src/modules.cc, src/modules.h, src/processor.cc,
	src/processor.h, src/symbol.cc, src/symbol.h: Removed deprecated
	code for setting/getting attributes. Added a new member function
	to the module_symbol that allows a character string to assign
	values to a module (this doesn't do anything yet).

	* modules/resistor.cc, modules/resistor.h, modules/usart.cc,
	modules/usart.h: removed deprecated set_attribute member function.

2004-12-06 Scott Dattalo <scott@dattalo.com>
	* cli/socket.cc: Experimenting with binary data. Cleaned up socket
	link creation. Added a generic symbol read/write socket command.

2004-12-06 Scott Dattalo <scott@dattalo.com>
	* cli/socket.cc: Wrap gtk2.x calls with #defines

2004-12-02 Scott Dattalo <scott@dattalo.com>
	* cli/socket.cc: More additions to SocketLinks. It's now possible
	to tie a socket to a gpsim attribute. This allows an external
	application to directly control gpsim's behavior.

2004-12-02 Scott Dattalo <scott@dattalo.com>
	* src/pic-processor.h, src/pic-processor.cc, src/p16f87x.h,
	src/p16f87x.cc: Added the PIC 16f876

2004-12-01 Scott Dattalo <scott@dattalo.com>
	* cli/socket.cc: Fixed the socket interface for issues related
	to gtk 2.x. Began adding the SockeLink class. This class will
	sit on top of the socket interface and will hide it from the 
	clients. The clients will be able to open SocketLinks and connect
	directly to gpsim internal objects.

2004-12-01 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def: MSVC sync

2004-11-30 Scott Dattalo <scott@dattalo.com>
	* gpsim/gpsim.vcproj: Removed references to files resource.h and
	gpsim.rc.

2004-11-30 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_break.cc, cli/cmd_break.h, cli/cmd_help.cc, cli/cmd_help.h,
	cli/cmd_load.cc, cli/cmd_load.h, cli/cmd_log.cc, cli/cmd_log.h,
	cli/cmd_macro.cc,, cli/cmd_macro.h, cli/cmd_module.cc, cli/cmd_module.h,
	cli/cmd_processor.cc,, cli/cmd_processor.h, cli/cmd_symbol.cc,
	cli/cmd_symbol.h, cli/command.cc, cli/misc.h, cli/parse.yy, cli/scan.ll:
	Changed the parser token STRING to LITERAL_STRING_T. The reason for
	this is to allow string type attributes to be treated like numeric 
	attributes.
	* src/pic-processor.cc, src/pic-processor.h, src/processor.cc,
	src/processor.h, src/symbol.cc, src/symbol.h, src/value.cc,
	src/value.h:
	- Enhanced the 'String' class so that 1) it uses char * instead
	of STL string (yes this IS an enhancement) 2) the set() and get()
	methods can read and write to the String class.
	- Changed many instances of 'char *' to 'const char *'.

2004-11-29 Scott Dattalo <scott@dattalo.com>
	* src/pic-processor.cc, src/processor.cc, src/processor.h,
	src/trace.cc, src/value.cc, src/value.h: Change Integer,
	Boolean, and Float classes back to hold values of native types
	(as opposed to holding pointers to the native types).
	* modules/video.cc: changed reference to cpu->frequency to 
	cpu->set_frequency

2004-11-29 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_stimulus.cc: register stim were not getting started.
	* regression/register_stim/register_stim.[asm|stc], 
	regression/run_regression.sh:
	Added a regression test for register stimuli.
	
2004-11-29 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.h, src/stimuli.cc, src/value.cc, src/value.h: Redesigned
	the 'asynchronous_stimulus' to be a 'ValueStimulus'.
	Added a new stimulus type: AttributeStimulus. An attribute stimulus
	is a stimulus that can be tied directly to some attribute. For example,
	a register symbol is a type of attribute. So an attribute stimulus
	can be tied to a register symbol to create a 'register stimulus'.
	* cli/cmd_stimulus.cc, cli/command.cc, cli/parse.yy: Added support
	for attribute stimuli.

2004-11-28 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def: MSVC sync

2004-11-24 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc: operator[] for FileContext was not checking
	negative indices.

2004-11-24 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc: yet another attempt to fix tab completion.
	* modules/binary_indicator.cc, modules/binary_indicator.h
	modules/bitlog.h, modules/led.h, modules/logic.cc, modules/logic.h,
	modules/paraface.h, modules/resistor.cc, modules/video.cc,
	modules/video.h: Changed IO_input to IOPIN for all pins. This
	is an attempt to remove a warning message regarding IO_input that
	is generated while building under CygWin.
	* modules/makefile.mingw, plat/win32/gpsim.nsi: Renamed modules.dll
	to a slightly more descriptive gpsim_modules.dll 
	* src/i2c-ee.cc, src/p12.cc, src/p16f62x.cc, src/p17c75x.cc, 
	src/stimuli.h: exchanged references to IO_input to IOPIN.

2004-11-23 Scott Dattalo <scott@dattalo.com>
	* plat/win32/gpsim.def, modules/modules.vcproj: MSVC sync
	* modules/*.cc: removed (char *) casts in calls to new_name()
	* gpsim/main.cc: removed some unnecessary includes.
	* gpsim/gpsim.vcproj: MSVC sync
	* cli/input.cc: removed some debug stuff
	* cli/cmd_log.cc: removed unreferenced variable.

2004-11-23 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def, modules/modules.vcproj: MSVC sync

2004-11-23 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc: The tab completion fix for window's now causes
	a crash on Linux. Sigh. Now both oses are supported (without crashes)
	
2004-11-23 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc: Fixed tab completion related window's crash
	* gui/gui_symbols.cc: Windows doesn't support strndup()
	
2004-11-22 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc: buffer overflow in command_generator().
	* src/ioports.cc, src/pic-registers.cc, src/registers.cc,
	src/stimuli.cc: valgrind check - unitialized memory.
	* src/value.h, src/value.cc, src/interface.h, src/symbol.cc,
	src/symbol.h, gui/gui_profile.cc, gui/gui_regwin.cc, gui/gui_regwin.h,
	gui/gui_src.cc, gui/gui_src.h, gui/gui_src_asm.cc, gui/gui_stack.cc,
	gui/gui_symbols.cc, gui/gui_watch.cc, gui/gui_watch.h:
	The gui was accessing the symbol table improperly. A new 
	Symbol_Table_Iterator class was created to abstract accesses to the 
	symbol table. In addition, get() and set() methods were added to
	the symbol classes that will allow reading/writing symbol values
	using strings.
	
2004-11-19 Scott Dattalo <scott@dattalo.com>
	* gui/gui_breadboard.cc, gui/gui_regwin.cc, cli/parse.yy: valgrind
	check - fixed some uninitialized memory.
	
2004-11-19 Scott Dattalo <scott@dattalo.com>
	* gui/gui_breadboard.cc: Don't let modules open a closed breadboard 
	window.
	
2004-11-18 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc: disallow TAB characters under windows since it
	causes a crash most of the time.
	* modules/bitlog.cc, modules/bytelog.cc, modules/ttoken.cc,
	modules/makefile.mingw: These were not getting built under windows.
	* plat/win32/gpsim.nsi: added pthreadVC.dll to gpsim's windows binary
	distribution.
	* doc/gpsimWin32.html: Updated documentation for pthreads.
	
2004-11-17 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc, src/value.cc, src/value.h: made Integer,Float
	and Boolean values get() and set() their values through just one
	member function. This allows derived attributes to trap reads and
	writes to the values.
	
2004-11-16 Scott Dattalo <scott@dattalo.com>
	* src/value.h, src/value.cc, src/processor.h, src/processor.cc,
	src/pic-processor.cc, src/symbol.h, src/symbol.cc: Added 3 new
	attributes: SafeMode, WarnMode, and UnknownMode to control the
	simulator's behavior under certain simulation conditions. Attribute
	handling has also been enhanced.
	* cli/parse.yy, cli/cmd_help.cc, cli/cmd_help.h: Help command
	will display information about attributes.
	
2004-11-15 Scott Dattalo <scott@dattalo.com>
	* src/ioports.h, src/ioports.cc, src/16bit-registers.cc: Beginning
	to redesign I/O ports.

2004-11-14 Scott Dattalo <scott@dattalo.com>
	* src/i2c-ee.cc, src/ioports.cc, src/ioports.h, src/stimuli.cc,
	src/uart.cc: The usart has bitrotted. The relatively recent I/O pin
	changes broke this and probably other peripherals too.
	* modules/Makefile.am: added new files.
	* modules/pthread-wrap.h, modules/ttoken.cc, modules/ttoken.h:
	The token class provides co-routine support for modules.
	* modules/bitlog.cc, modules/bitlog.h, modules/bytelog.cc,
	modules/bytelog.h: Bit and Byte event loggers. bitlog was originally
	part of the uart module.
	* modules/usart.cc, modules/usart.h: removed the bit logger class and
	am now making an attempt to resurrect this code. 

2004-11-10 Scott Dattalo <scott@dattalo.com>
	* cmd/cmd_break.cc: updated the help description for 'break'
	* src/operator.cc, src/symbol.h, src/symbol.cc: Allow registers
	to be type-cast into integers.

2004-11-10 Scott Dattalo <scott@dattalo.com>

2004-11-07 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def, plat/win32/gpsim.nsi, src/makefile.mingw,
	  src/src.vcproj: MSVC sync
	* doc/gpsimWin32.html: updated glib version to 2.4.7, gtk+ version to 2.4.13

	gui/gui_symbol.cc, src/symbol.cc, src/symbol.h, src/value.cc
	src/value.h:
	gpsim symbols now support more of the methods of the Value class.
	
2004-11-05 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_clear.cc, cli/cmd_disasm.cc, cli/cmd_set.cc
	cli/command.cc, cli/scan.ll, gui/gui_breadboard.cc, src/errors.cc
	src/expr.cc, src/operator.cc, src/value.cc, src/value.h:
	Cleaned up the Value class. 

2004-11-05 Scott Dattalo <scott@dattalo.com>
	* src/attribute.h, src/attribute.cc, Makefile.am: Removed attribute.*
	from gpsim. The class 'Value' has replaced it.
	
2004-11-04 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_break.cc, cli/cmd_log.cc, cli/cmd_symbol.cc, cli/cmd_x.cc,

	src/processor.h, src/symbol.cc, src/symbol.h, src/value.cc,
	src/value.h:
	- Rearranged class heirarchy so that gpsimValue derives from
	gpsimObject instead of Value.
	- Substitued the Value class for those places where the Attribute
	class is used.
	* modules/encoder.cc, modules/led.cc, modules/logic.cc, 
	modules/push_button.cc, modules/resistor.cc, modules/switch.cc,
	modules/usart.cc, modules/video.cc

2004-11-04 Scott Dattalo <scott@dattalo.com>
	* regression/create_stc, regression/simulate, src/expr.cc,
	src/symbol.cc, src/symbol.h, src/value.cc:
	Regression tests were failing due to recent parser changes.

2004-11-03 Scott Dattalo <scott@dattalo.com>
	* cli/parse.yy, cli/scan.ll, src/14bit-registers.cc, src/16bit-instructions.cc,

	Added command line assignments. Now you can write stuff like:
	  temp1 = temp2 << 4
	where temp1 and temp2 are two registers.

2004-11-02 Scott Dattalo <scott@dattalo.com>
	* src/attribute.cc, src/attribute.h, src/modules.cc, src/modules.h:
	cleaned up include dependencies.

2004-11-02 Scott Dattalo <scott@dattalo.com>

2004-10-20 Scott Dattalo <scott@dattalo.com>
	* src/16bit-instructions.cc: Fixed bug in DECF instruction.
	* regression/instructions_16bit/instructions_16bit.asm: Added
	decf instruction to the regression test.
	
2004-10-20 Scott Dattalo <scott@dattalo.com>
	* src/ioports.cc, src/ioports.h, src/stimuli.cc, src/stimuli.h:
	PORTB pullups updated. 
	Added an overloaded update() member to Stimulus_Node that doesn't
	require time as an input (we never used it anyway).
	
2004-10-19 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.h, src/stimuli.cc, src/ioports.cc, src/i2c-ee.cc:
	Optimized I/O port stimulus updates.

	to stimuli.

2004-10-18 Scott Dattalo <scott@dattalo.com>
	* src/gpsim_classes.h, src/registers.h: Added EXTERNAL_RESET and
	BOD_RESET types.
	
2004-10-17 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def: MSVC sync
	* src/symbol.cc: fixed gpsim crash on WIN32 in remove_module()

2004-10-13 Scott Dattalo <scott@dattalo.com>
	* src/cod.cc: Applied patch from Craig Franklin that adds support
	for reading .cod file message area.

2004-10-12 Scott Dattalo <scott@dattalo.com>
	* src/gpsim_time.cc: Added diagnostic printf's
	* src/pic-processor.cc, src/pic-processor.h, src/processor.cc,
	src/processor.h: add an option to not update the gui while single
	stepping.

2004-10-11 Scott Dattalo <scott@dattalo.com>
	* src/cod.cc, src/processor.cc: Applied, but modified, patch from
	Craig Franklin that brings gpsim up to date with new gputils release.

2004-10-07 Scott Dattalo <scott@dattalo.com>
	* gui/gui_breadboard.cc, gui/gui_breadboard.h, gui/gui_menu.cc:
	Cleaned up the gui breadboard code a little by making the gui_module
	structure a GuiModule class. In addition, new modules are queued 
	into the breadboard and realized only after the breadboard has
	been built.
	
2004-10-07 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_opcode.cc: window was being built before cpu had been
	initialized.
	* cli/cmd_disasm.cc, src/processor.cc, src/trace.cc: Disassembling
	and tracing had wrong addresses for the 18F family (again...)
	
2004-10-06 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src.h, gui/gui_src_asm.cc, gui/gui_src_opcode.cc,
	gui/gui_statusbar.cc, src/breakpoints.cc: Fixed breakpoint
	icon refreshing. Also fixed  Source browser window creation if either
	~/gpsim is missing or the registry hasn't been initialized

2004-10-05 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc: Moved the creation of the Search Dialog
	window out of Build() and into its own function. Changed the behavior 
	of the signal callbacks to conform to GTK+ 2.X

2004-10-04 Scott Dattalo <scott@dattalo.com>
	* README, INSTALL: Cleaned up stale documentation.
	
2004-10-04 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc: Send an extra CR to the parser when loading a
	command file. Turns out that when the gui loads a file, the
	parser doesn't process it until another CR is seen.
	
2004-10-04 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc, gui/gui_regwin.cc, gui/gui_breadboard.cc:
	Removed some debugging printfs.
	* gui/gui_object.cc:
	With GTK+ 2.2.1 under linux, the gtk_widget_show() was losing
	the (x,y) position of the window.
	
2004-10-04 Scott Dattalo <scott@dattalo.com>
	* gui/gui_breadboard.cc, gui/gui_breadboard.h:
	The breadboard expose events invalidated drawing areas which in
	turn recursively generated expose events. I'm not sure why this
	code worked with GTK+ 1.x

2004-10-04 Scott Dattalo <scott@dattalo.com>
	* gui/gui_breadboard.cc, gui/gui.h, gui/gui_stopwatch.cc,
	gui/gui_object.cc, gui/gui_main.cc, gui/gui_object.h,

	gui/gui_stack.cc, gui/gui_stopwatch.cc, gui/gui_symbols.cc,
	gui/gui_trace.cc, gui/gui_watch.cc:
	Work in progress - trying to resolve breadboard start up
	issues with GTK+ 2.X .

2004-10-03 Borut Razem <borut.razem@siol.net>
	* config_win32.h.in, plat/win32/configure_win32.awk,
	  cli/cli.vcproj, src/src.vcproj,
	  plat/win32/make.mingw, makefile.mingw, cli/makefile.mingw, gpsim/makefile.mingw,
	  gui/makefile.mingw, modules/makefile.mingw, src/makefile.mingw:
	  added configure_win32.awk script, which takes version number from
	  configure.in and inserts them into config_win32.h.in and generates cofig.h
	* plat/win32/gpsim.def: MSVC sync

2004-10-01 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc, src/processor.h, gui/gui.h, gui/gui_regwin.c
	gui/gui_asm.cc, gui/gui_src_opcode.c, plat/win32/make.mingw:
	Stabilizing windows port. Apparently under windows there's a
	problem if you issue too many gui calls to the GTK library. I
	found that this can be mitigated by periodically clearing out
	the gtk event queue.

2004-09-29 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc, gui/gui_menu.cc, gui/gui_src_asm.cc, 
	src/modules.h, src/modules.cc, src/processor.cc,
	src/pic-processor.cc, src/pic-processor.h, src/trace.h
	plat/win32/gpsim.def: Clean ups to get the Windows
	port to compile.

2004-09-29 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc, src/pic-instructions.cc: Uninitialized variables
	in the instruction class were causing the source browser to
	place objects beyond the range allocated to the source browser.
	This confused GTK+ 2.x.

2004-09-28 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_load.cc, cmd/input.cc:
	Allow loading of filenames with spaces. (note, gpsim's
	command line interface still does not support this).

2004-09-28 Scott Dattalo <scott@dattalo.com>
	* gui/gui_main.cc, gui/gui_menu.cc, gui/gui_object.cc, 
	gui/gui_object.h, gui/gui_regwin.cc, gui/gui_src.h,
	gui/gui_src_asm.cc, src/gpsim_interface.h, M src/interface.cc:
	- Fixed a few bugs caused by upgrading to GTK+ 2.x:
	  -- Window state was not being saved
	  -- Register window font was fouled up
	  -- Source browser pixel position calculations are different
	  There are still some other bugs that need to be fixed: 
	  -- The breadboard window somehow prevents the Source browser
	     window from opening
	  -- <control>Q no longer quits
	  -- scrolling in source browser only works if the scroll pane
	     has focus
	  -- The register window cheats in guessing character width.

2004-09-24 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc: save_state() was skipping address 0.
	* src/registers.cc: Bit string encoding has been enhanced

2004-09-15 Scott Dattalo <scott@dattalo.com>
	* gui/gui_regwin.h, gui/gui_regwin.cc: max allowable registers
	is 64k (used to be 4k)
	* gui/gui_src_asm.cc: improperly initialized instructions were
	causing a core dump.

2004-09-19 Borut Razem <borut.razem@siol.net>
	* configure.in: gpsim is configured to link with GTK+ 2.x by default.
	  Use --enable-gtk1 for linking with GTK+ 1.x (deprecated).

2004-09-15 Scott Dattalo <scott@dattalo.com>
	* gui/gui_regwin.cc, gui/gui_src_asm.cc: Fixed ranging checks.

2004-09-15 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc, src/processor.h, src/pic-processor.cc:
	getWriteTT and getReadTT used to return TraceType objects,
	but now they return unsigned ints.

2004-09-15 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc, src/trace.cc, gui/gui_src_opcode.cc:
	- 18f processors' addresses were off by a factor of two in
	disassembly operations.

2004-09-14 Borut Razem <borut.razem@siol.net>
	* cli/cli.cvproj, src/src.vcproj, plat/win32/gpsim.def: MSVC sync
	* cli/makefile.mingw, src/makefile.mingw: MinGW sync
	* plat/win32/gpsim.nsi: corrected revision number to 0.22.3

2004-09-14 Scott Dattalo <scott@dattalo.com>
	* regression/p12ce518/p12c518.asm, regression/p12ce518/p12c518.stc,
	regression/p12ce518/EEdriver.asm: Added a regression test
	for the 12ce518.
	* src/stimuli.cc, src/i2c-ee.cc, src/ioports.cc, src/stimuli.h,
	src/14bit-registers.cc:
	Fixed stimuli so that the 12CE518 internal EEPROM would work.
	
2004-09-13 Scott Dattalo <scott@dattalo.com>
	* src/i2c-ee.cc, src/i2c-ee.h, src/ioports.cc, src/p12x.cc,
	src/stimuli.cc, src/stimuli.h: Partially check in for work
	on the 12ce518 bug (internal I/O pins).

2004-09-12 Scott Dattalo <scott@dattalo.com>
	* cli/Makefile.am, cli/errors.cc, cli/errors.h:
	* src/Makefile.am, src/errors.cc, src/errors.h:
	Moved errors.* from cli/ to src/
	* src/expr.cc, src/operator.cc, cli/cmd_disasm.cc,
	cli/cmd_set.cc, cli/cmd_x.cc, cli/command.cc, cli/command.h,
	cli/parse.yy, cli/scan.ll:
	Updated the directory path for including errors.h.

2004-09-12 Borut Razem <borut.razem@siol.net>
	* cli/cli.cvproj, src/src.vcproj, plat/win32/gpsim.def: MSVC sync
	* cli/makefile.mingw, src/makefile.mingw, gpsim/makefile.mignw: MinGW sync

2004-09-11 Scott Dattalo <scott@dattalo.com>
	* configure.in: Bumped the Revision up to 0.22.3 since there
	have been *so* many changes.
	* cli/expr.h, cli/expr.cc, cli/operator.cc, cli/operator.h:
	  - moved to the src/ directory
	* src/expr.h, src/expr.cc: copied from the cli/ directory
	* src/Makefile.am, cli/Makefile.am
	* src/symbol.h, src/value.h, src/symbol.cc, src/value.cc:
	  - It turns out that gpsim's symbols are essentially identical
	to the value objects that were recently added to support
	expression parsing. Since expressions need to handle symbols
	too, I decided to make the Value class a base class for 
	gpsimValue. Now, much of what has been written for 
	expressions will naturally handle many of gpsim fundamental
	types.
	* src/pic-processor.cc, src/pic-processor.h, src/eeprom.cc,
	src/eeprom.h, src/14bit-registers.cc: The W register, eeprom,
	and option register states were not saved during a processor
	'save_state()' call.
	* src/p12x.cc: internal 12ce518 i2c module was not connected 
	correctly.
	* cli/cmd_clear.cc, cli/cmd_disasm.cc, cli/cmd_frequency.cc,
	cli/cmd_log.h, cli/cmd_macro.cc, cli/cmd_module.h,

	* cli/cmd_x.cc, cli/expr.cc, cli/expr.h, cli/operator.cc,
	cli/operator.h, cli/parse.yy, cli/scan.ll:
	 - Added command line comparison expressions.
	* src/pic-processor.cc, src/pic-registers.cc, src/symbol.cc,
	src/symbol.h, src/value.cc, src/value.h:
	- Added support for a generic symbol type.
	- Added the pic PC object to the symbol table.
	* regression/digital_stim/digital_stim.stc:
	The new expression parsing introduced a grammer conflict that
	requires a stimulus data list to be expressed differently.

2004-09-08 Scott Dattalo <scott@dattalo.com>
	* src/14bit-registers.h, src/14bit-tmrs.h, src/breakpoints.cc,

	gui/gui_profile.cc, modules/encoder.h, modules/paraface.h
	modules/usart.cc:
	Started adding Triggers and Actions.
	* regression/run_regression.sh: Added the digital_stim 
	regression test to the list of tests to run.

2004-09-07 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.cc, src/stimuli.h, cmd_x.cc, cmd_stimulus.cc:
	Digital asynchronous stimuli were not getting the proper voltage
	data values. 
	Enhanced the asynchronous stimulus by making the data array an
	array of C++ objects instead of a type casted structured.

2004-09-06 Scott Dattalo <scott@dattalo.com>
	* examples/14bit/analog_stim2.stc, examples/14bit/ap.stc,
	examples/14bit/async_pulse.stc, examples/14bit/async_stim2.stc,
	examples/14bit/dtmf.stc, examples/12bit/gpio_stim.stc:
	- Updated the asynchronous stimulus syntax in all of the example
	startup scripts

2004-09-05 Scott Dattalo <scott@dattalo.com>
	* src/ioport.cc, src/stimuli.cc:
	Applied patch from Robert Pearce regarding I/O Pins and stimuli
	Fixed a couple more issues with I/O pins and contention.

2004-09-02 Borut Razem <borut.razem@siol.net>
	* cli/socket.cc: read complete line before procesing,
	  support for different line endings (LF, CR-FL)
	* cli/cmd_macro.cc: enable compilation on VS 7.1

2004-09-02 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_macro.cc:
	Clarified the help description for the macro command.
	
2004-09-02 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_macro.cc, cli/cmd_macro.h, cli/scan.h, cli/scan.ll: 
	Completed support for parameterized macros

2004-09-02 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_macro.cc, cli/cmd_macro.h, cli/input.cc,
	cli/parse.yy, cli/scan.ll: Added support for parameterized
	macros. This is not completed

2004-09-02 Borut Razem <borut.razem@siol.net>
	* cli/input.cc, cli/socket.cc: socket port to WIN32
	* gpsim/gpsim.vcproj, cli/cli.vcproj, cli/makefile.mingw,
	  gpsim/makefile.mingw: added cmd_macro.* and socket.cc to
	  the project, wsock32.lib dependency

2004-09-01 Scott Dattalo <scott@dattalo.com>
	* cli/parse.yy: Fixed a bug that caused old versions of bison
	to choke.
	
2004-09-01 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_macro.cc, cli/input.cc:
	Converted the LLInput struct into a class. Now, the macro
	command can invoke a macro and redirect it's output to the
	parser stream.
	* src/trace.cc, src/trace.h:
	Added the ProcessorTraceObject to the TraceObject heirarchy.
	Now, TraceObjects no longer store info about a processor.
	(Thus modules can be processor agnostic.)
	
2004-09-01 Scott Dattalo <scott@dattalo.com>
	* src/p16x5x.cc: The 16C55 processor was only declaring a 
	package of 18 pins (instead of 28).

2004-08-31 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_macro.cc, cli/cmd_macro.h:
	Added the 'macro' command.
	* cli/Makefile.am, cli/parse.yy, cli/command.cc, cli/scan.ll:
	Parser now calls the gpsim command cmd_macro.
	
2004-08-31 Scott Dattalo <scott@dattalo.com>
	* cli/scan.ll, cli/parse.yy:
	Added language support for macro definitions. (although,
	macros are not yet supported).
	
2004-08-29 Borut Razem <borut.razem@siol.net>
	* plat/win32/gsim.def, cli/makefile.migw, src/makefile.migw,
	  cli/cli.vcproj, src/src.vcproj: updated
	* cli/errors.h, cli/scan.ll: corrected include paths
	* plat/win32/gpsim.nsi: gpsom.pdf included in WIN32 setup
	* doc/gpsimWin32.html: gtk+ 2.4.7

2004-08-27 Scott Dattalo <scott@dattalo.com>
	* src/breakpoints.cc, src/gpsim_object.cc, src/gpsim_object.h,
	  src/modules.cc, src/modules.h, src/pic-processor.cc,
	  gui/gui_src_asm.cc, gui/gui_statusbar.cc:
	The Module class was overriding functionality provided in the
	gpsimObject class. This caused problems for external processors 
	(That is, processors not a part of gpsim).

2004-08-26 Scott Dattalo <scott@dattalo.com>
	* src/gpsim_object.cc, src/gpsim_object.h: New files that
	support the gpsimObject class. This is a base class for 
	almost all gpsim objects.
	* cli/viewable.cc, cli/viewable.h: Removed. The functionality
	that was provide by these was moved to gpsimObject.
	* src/Makefile.am, src/modules.h, src/registers.cc,
	  src/registers.h, src/symbol.cc, src/value.cc, src/value.h,

	* src/stimuli.cc, src/symbol.cc, src/symbol.h,
	  gui/gui_profile.cc, gui/gui_stack.cc, gui/gui_symbols.cc
	  cli/scan.ll:
	The symbol class is now derived from the gpsimValue class.
	This change allows some of the recent enhancements created
	for other things to be applied to symbols as well.
	* examples/14bit/p16c64_pwm.stc, examples/14bit/portc_stim.stc:
	The PWM module was crashing. I'm not sure why, but I think
	what actually was happening that the example stc file
	was just broken.

2004-08-25 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_trace.cc, src/14bit-registers.cc, src/trace.cc,
	  src/trace.h: Removed a stale option to the trace command
	and added a new option that will allow the decode trace
	buffer to be saved to a file.

2004-08-25 Manuel Bouyer <bouyer@antioche.eu.org>
	* src/stimuli.cc: fixed bug in finding the node voltage when
	3 or more stimuli are attached to a node.

2004-08-24 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.cc: Attaching three or more stimuli to
	one node caused gpsim to hang.

2004-08-24 Manuel Bouyer <bouyer@antioche.eu.org>
	* src/stimuli.cc: Fixed iopin stimulus update.

	  cli/cmd_symbol.h, cli/expr.cc, cli/expr.h, cli/parse.yy,
	  cli/scan.ll, src/stimuli.cc, src/stimuli.h, src/symbol.h:
	The attach command can now accept a list of symbols. Also,
	Nodes and stimuli are now added to the symbol table whenever
	they're constructed.

2004-08-19 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc: writeTT and readTT were not initialized
	in Processor constructor.

2004-08-18 Scott Dattalo <scott@dattalo.com>
	* src/registers.cc, src/registers.h, src/symbol.cc,
	  src/symbol.h, src/trace.cc, src/trace.h, cli/cmd_symbol.cc,
	  cli/cmd_symbol.h, cli/expr.cc, cli/expr.h, cli/parse.yy,
	  cli/scan.ll:
	More improvements to tracing.
	Added some more symbolic command line processing.

2004-08-16 Scott Dattalo <scott@dattalo.com>
	* src/trace.cc, src/trace.h:

	  cli/cmd_trace.cc:
	Two categories of changes have been made: First, the unitialized register
	concept has been propogated to all of the register constructions. Second,
	tracing has been improved yet again.

	* plat/win32/gpsim.nsi: packaging of MinGW executables
	* gpsim/gpsim.vcproj: cleanup
	* plat/win32/make.mingw, cli/makefile.mingw, gpsim/makefile.mingw,

	src/pic-registers.cc, src/trace.cc, src/trace.h: The newly rewritten
	trace printing code was broken. The good news is that while fixing
	it, I found a way to save a little simulation time by not tracing
	the instruction opcodes.

2004-07-29 Scott Dattalo <scott@dattalo.com>
	* src/ioports.cc, src/ioports.h, src/modules.cc, src/registers.cc,

	modules/paraface.h, modules/resistor.cc, modules/resistor.h,
	modules/usart.cc, modules/video.cc, modules/video.h:
	Rewrote the way stimuli are handled. Before, gpsim only used
	a single parameter (more or less) to represent the state of
	an stimulus. Now, two parameters are used. Currently, these
	parameters are designated as the voltage and impedance. Before,
	the single parameter was somewhat similar to a current.

	* cli/input.c: define gpsim_rl_getc() only if defined HAVE_READLINE &&
	  defined HAVE_GUI

2004-06-09 Scott Dattalo <scott@dattalo.com>
	* cli/expr.cc, cli/expr.h, cli/viewable.h, cli/viewable.cc, 
	cli/operator.h, cli/operator.cc: New files to support parsing
	* cli/parse.yy, cli/scan.ll: added new parsing and lexing rules
	for expression parsing.
	* src/stimuli.cc: Manuel Boyer found and fixed a bug where the
	a named stimulus was ignoring its newly assigned name.

2004-06-09 Scott Dattalo <scott@dattalo.com>
	* cli/parse.yy, cli/scan.ll, cli/misc.h, cli/cmd_stimulus.cc, cli/command.h
	Cleaned up the parser by removing the explicit YYABORT and YYACCEPT macros.
	Also, redesigned the parser implementation of the stimulus command.
	
2004-06-03 Scott Dattalo <scott@dattalo.com>
	* examples/12bit/it_12bit.asm: removed
	* regressions/instructions_12bit/instructions_12bit.asm: added

	* src/eeprom.cc: The eeprom memory access object was not getting
	initialized.
	* src/stimuli.cc: applied patch from Manuel Boyer. The IO_open_collector
	was duplicating the base class' job of setting the pin name.
	
2004-06-02 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_break.cc, src/processor.cc: 18fxxx addressing was broken.

	correctly.)
	
2004-06-01 Scott Dattalo <scott@dattalo.com>
	* src/value.h: Made the string &name() member function in the 
	gpsimValue class virtual.
	
2004-05-31 Scott Dattalo <scott@dattalo.com>
	* almost all files: Since the Register class and the Instruction class
	are now derived from gpsimValue, all objects that use registers
	and instructions have to change. These changes have been propogated
	through gpsim. Next, the gui will start taking advantage of the
	abstractness that this change introduces.
	* src/16bit-instructions.cc, src/14bit-instructions.h: Manuel Boyer
	reported two bugs with the 16bit subwf instruction. He fixed one
	(N-bit was ignored) with a patch and I fixed the other (OV bit was 
	ignored).

2004-05-27 Scott Dattalo <scott@dattalo.com>
	* src/value.h, src/value.cc: New files that support abstract values.
	* src/register.h, src/pic-instructions.h:
	Now all base objects that have values are derived from the new
	gpsimValue object.

	support a customizable message that will be displayed when the
	break is encountered.

2004-05-21 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc, src/register.h, register.cc, gui/gui_register.h,

	* src/register.h: Added new accessor member functions to the Register
	class to manipulate the new way register values are represented.
	
2004-05-20 Scott Dattalo <scott@dattalo.com>
	* Tons of files... Changed the Register class' 'unsigned int value'
	field to an object. The get() and put() accessor functions now provide
	read and write access.

2004-05-20 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc: Syntax highlighting now is only applied to lines
	that are associated with generated code.
	
2004-05-16 Scott Dattalo <scott@dattalo.com>
	* src/processor.h, src/processor.cc:
	Added mapping between program memory and source file line numbers

2004-05-15 Scott Dattalo <scott@dattalo.com>
	* src/pic-processor: If the simulation is started from an address that has
	an execution break, now gpsim will ignore that break.
	* xpm/canbreak.xpm: New xpm that's used to indicate source lines that will
	accept breakpoints.
	* gui/gui_src.h, gui/gui_src_asm.h: Added 'canbreak' XPM to the source
	browser lines that can accept break points. NOTE: this code currently
	leaks memory!

2004-05-12  Manuel Bouyer <bouyer@antioche.eu.org>
	* src/16bit-instructions.cc, src/p18x.cc, src/p18x.h, src/pic-instructions.cc,
	 src/pic-processor.cc, src/pic-processor.h: Fix usart problems in 18x devices.
	* src/pir.cc, src/pir.h, src/uart.cc, src/uart.h: Fix usart bugs.
	(Changes were submitted as a patch and applied by Scott).
	
2004-05-15 Scott Dattalo <scott@dattalo.com>
	* src/xref.h, xref.cc: added get_value() member function to XrefObject class

	access

2004-04-21 Borut Razem <borut.razem@siol.net>
	* src/gpsim_interface.h, src/gpsim_time.h, src/processor.cc, src/symbol.cc,
	src/trace.cc: create instances of inline methods by taking theirs address,
	so that they can be accessed from dynamic loadable modules

2004-04-19 Scott Dattalo <scott@dattalo.com>
	* modules/binary_indicator.cc, modules/encoder.cc,
	modules/gpsim_modules.cc, modules/led.cc, modules/logic.cc,

	* src/14bit-tmrs.cc: The TMR2 peripheral failed to properly clear
	its breakpoint whenever it was being turned off.
	*src/modules.h: string.h was not getting included.
	
2004-04-13 Scott Dattalo <scott@dattalo.com>
	* src/breakpoints.cc, src/breakpoints.h: 
	Redesigned breakpoints so that a) they're more object oriented and b) more
	easily extensible.

	and redesigning the whole Breakpoint class.
	
2004-04-07  Bert Driehuis <driehuis@playbeing.org>
	* extras/lcd/lcd.cc:  reference was made to a no-longer existing API
	* extras/lcd/module_manager.cc: contained comments
	which were out of date, that hampered readability.
	* src/modules.cc: will not load two shared extension modules, if the
	first does not have an "initialize" routine. As a side effect of
	debugging this one, the error reporting of the dynaloader has been
	expanded. The trick turned out to be to clear pre-existing error
	conditions with a dummy call to dlerror(). An alternative
	implementation would call dlerror in an else clause when loading
	"initialize" fails, but doing it like this patch does it has the
	advantage of also dealing with like errors in libraries gpsim might
	use. For a similar situation, look up "not a typewriter" and "perror"
	in Google.
	- did not immediately fail when incomplete linking
	conditions exist. By changing to RTLD_NOW, a bad dynamic module will
	be detected at load time rather than at run time. *** this will break
	broken modules out there that until now appeared to have worked ***

	browser windows can now get a unique name.
	
2004-03-30 Scott Dattalo  <scott@dattalo.com>
	* numeous files throughout gpsim: The Module class now uses 
	a string type instead of a 'char *' for the module name. Also,
	the gui x and y coordinate were removed from the module class (I
	still want to remove the 'widget' member too).
	* modules/usart.cc: calls to the old gpsim api were still lingering
	around here.
	* gui/gui_src_asm.cc, gui/gui_src.h, src/processor.h: more browser
	splitting stuff.

	The GUI_Object 'name' member has been changed from a char * to a
	private string and is now no longer directly accessed by the derived
	classes. New methods set_name() and and name() control the access.
	
2004-03-24 Scott Dattalo  <scott@dattalo.com>
	* gui/gui_src_asm.cc, gui/gui_src.h: Added BreakPointList class to handle

	cli/cmd_x.cc, cli/cmd_run.cc, cli/cmd_dump.h, cli/cmd_dump.cc:
	The gpsim library, which is the code comprised of everything
	in the src/ subdirectory, now has no dependencies on the gui
	or cli code base. This makes it possible to link against
	just libgpsim. 

2004-02-25 Scott Dattalo  <scott@dattalo.com>
	* gui/gui_stopwatch.cc, extras/rs232-gen/rs232-gen.c:
	changed all references of atoll to strtoll. bug 820326
	
2004-02-25 Hans-Juergen Dorn <hans.dorn@apl-landau.de>
	* src/16bit-registers.cc: gpsim was pushing onto
	the stack before decrementing the stack pointer. Also,
	the gpsim internally formatted address was being pushed.
	
2004-02-17  Scott Dattalo  <scott@dattalo.com>
	* gui/gui_scope.cc: expose and resizing kind of work.

2004-02-17  Scott Dattalo  <scott@dattalo.com>
	* gui/gui_scope.cc: taking off the rough edges.
	
2004-02-16  Scott Dattalo  <scott@dattalo.com>

	* gui/Makefile.am: add the gui_scope.cc to the list
	* gui/gui_regwin.cc: Check for null pointers
	* gui/gui_symbols.cc: Check for null pointers

	src/12bit-processors.h, src/12bit-processors.cc
	Added FSR_12 - a new class for the 12-bit core. I also redesigned the
	way FSR and INDF interact.
	* src/p18x.cc - the 18f252 package pins weren't defined.
	
2004-02-13  Scott Dattalo  <scott@dattalo.com>
	* src/processor.cc, src/processor.h, src/pic-processor.cc, src/cod.cc:
	Support for new file context
	* gui/gui_src_asm.cc, gui/gui_profile.cc:
	Use the new file context code.
	
2004-02-12  Scott Dattalo  <scott@dattalo.com>
	* src/interface.cc, src/interface.h:
	Finally, the C-style interface is gone (or nearly gone).
	* src/processor.cc, src/processor.h, src/cod.cc
	Redesigning the "file_context" object.
	* gui/gui_watch.cc, gui/gui_profile.cc:

2004-02-11  Scott Dattalo  <scott@dattalo.com>
	* gui/* changed calls to gpsim_* to the C++ interface.
	* src/interface.cc - removed many of the gpsim_* functions
	* src/stimuli.cc, cli/cmd_set.cc - changed calls to gpsim_* to
	the C++ interface.
	
2004-02-10  Scott Dattalo  <scott@dattalo.com>
	* src/processor.cc, src/processor.h, src/pic-processor.cc, src/pic-processor.h:
	Added step, run, and finish members to the ProgramMemoryAccess class

2004-02-10  Scott Dattalo  <scott@dattalo.com>
	* gui/gui_symbol.cc, src/symbol.h, src/symbol.cc
	Cleaned up symbol api.
	
2004-02-09  Scott Dattalo  <scott@dattalo.com>
	* all files!
	'NULL' has been replaced with '0' throughout all of gpsim.
	The reason is two-fold: 1) MAC users were having trouble compiling
	2) Stroustrup says NULL shouldn't be used in C++ :).
	
2004-02-08  Scott Dattalo  <scott@dattalo.com>
	* src/processor.cc, src/processor.h, gui/gui_src.cc, gui/gui_src_asm.cc,
	gui/gui_break.cc: Fixed 'ProgramMemoryAccess' class for the 18f devices
	* src/16bit-processors, src/p18x.cc: Removed some debug stuff
	* extras/lcd/*: Changed the LCD module from version 0.2.0 to 0.2.1
	
2004-02-06  Scott Dattalo  <scott@dattalo.com>
	* tons of files changed...
	Removed 'break_point' member from the Register class
	Changed the mechanism for checking how a break point is set on
	a register.
	* gui/gui.h, gui/gui_watch.cc, gui/gui_regwin.cc: modified GUIRegister
	class to adopt to changes made in the break point stuff. Also
	add rma member for getting access to processor registers.
	
2004-02-05  Scott Dattalo  <scott@dattalo.com>
	* src/pic-processor.h
	Fixed a nasty, nasty bug. The "GP_Processor" pointer in the
	pic_processor class was conditionally compiled. However the
	condition (HAVE_GUI) occurs in the include file config.h. Now
	the bug is that config.h was not included in all cases. Some
	classes were derived from pic_processor with this definition
	while others weren't. Syntactically, everything was okay. But
	the compile had the conflicting information for the size of
	pic_processor class.
	* src/* - whole bunch of other files touched while looking for
	this bug.

2004-02-04  Scott Dattalo  <scott@dattalo.com>
	* src/processor.cc
	Experimenting with operator [] for the ProgramMemoryAccess class.

2004-02-02  Scott Dattalo  <scott@dattalo.com>
	* src/intcon.*, src/processor.*, src/16bit-processor.*
	Fixed the weird bug that was discussed in the 2004-01-30 entry. The
	problem was basically invalid type casting. In the processor class
	heirarchy, there are about 5 or 6 levels of inheritance. Most of
	the time gpsim accesses a processor's details through one of the
	base classes. Sometimes though, an object needs access to somthing
	specific to a processor. In these cases, gpsim would type cast
	a pointer to the specific processor. The bug is that you can't
	safely type cast a base class object into a derived class object
	in C++.

2004-01-30  Scott Dattalo  <scott@dattalo.com>
	* almost all source files - still trying to sort out include 
	dependencies. There's a weird bug where gcc is adding an extra
	4-byte offset to pointers in some instances. I have no clue why...
	
2004-01-29  Scott Dattalo  <scott@dattalo.com>
	* almost all source files - trying to sort out include dependencies
	
2004-01-28  Scott Dattalo  <scott@dattalo.com>
	* src/pir.h moved all of the PIR*::put()'s to the PIR base class
	* src/intcon.h, src/intcon.cc moved inline functions that called
	bp and trace objects from the header file to the .cc file.
	* src/pir.cc new file - added so that inline functions that called
	bp and trace objects could be removed from the header file.
	* src/Makefile.am added pir.cc to the list of src files.
	
2004-01-26  Scott Dattalo  <scott@dattalo.com>
	* src/* gui/*
	  Replaced references to 'file_register' with 'Register'.
	  Removed many gpsim_*() calls. 
	  Renamed the program_memory_access class to ProgramMemoryAccess.
	  Moved processor member functions associated with code breakpoints
	  into the ProgramMemoryAccess class.
	
2004-01-26  Scott Dattalo  <scott@dattalo.com>
	* src/register.h, src/register.cc, src/pic-register.h, src/pic-processor.h,
	  src/14bit-registers.cc
	cleaned up some include file dependencies.
	moved the program counter class.
	
2004-01-23  Scott Dattalo  <scott@dattalo.com>
	* src/trace.cc, src/trace.h: added boolean event logger
	* src/intcon.cc, src/16bit-*: Debugging an interrupt problem
	with the 16-bit core
	
2004-01-22  Scott Dattalo  <scott@dattalo.com>

	into the CrossReferenceToGUI class.
	* src/pir.h: fixed default names of the PIR registers

2004-01-03  Scott Dattalo  <scott@dattalo.com>
	* Applied patch from Borut Razem - adds new files to Visual Studio project files.
	
2004-01-03  Scott Dattalo  <scott@dattalo.com>
	* Applied patch from Bradley McLean mailto:bradlist@bradm.net that adds support
	for the 18f1320.
	* Applied patch from Mike Durian that fixes an 18f SUB instruction.

2003-12-31  Scott Dattalo  <scott@dattalo.com>
	* Applied patch from Mike Durian. He's added several files to more reasonably
	group together portions of the simulator. In addition, he's added eeprom support
	to the 18f devices
	* src/eeprom.cc - new file to consolidate eeprom related stuff
	* src/intcon.cc - new file to consolidate variations in intcon registers
	* src/pie.cc - new file for pie register
	* src/intcon.h 
	* src/pir.h 
	* src/pic-instructions - fixed bug in 18f banking

	* cli/input.cc:
	    - added function get_dir_delim(), which searches for both /
	      and \ delimiters on WIN32 systems.
	    - fixed bug in gpsim_read(): logic for deallocating input_buf
	      was moved out of 'if (chars_left > 0)' block.
	    - some code cleaning, some compiler warnings fixed
	* cli/input.h:
	    - added declarations of exit_gpsim() and get_dir_delim()
	* gpsim/main.cc:
	    - removed declaration of exit_gpsim(), now included in cli/input.h
	* src/14bit-registers.cc:
	    - deallocation of name_str1 is already done in ~Register().
	* cod.cc:
	    - included cli/input.h for declaration of get_dir_delim()
	    - substr() replaced with get_string(), which gets the string from .cod
	      file. strings in .cod file are represented as:
	      - first byte defines the string length
	      - the string starts at the second byte.
	    - read_src_files_from_cod(): conversion to DOS file name
	    - open_cod_file() opens .cod file in binary mode
	* src/pic-instructions.cc:
	    - initialize xref to NULL if HAVE_GUI not defined
	* src/processor.cc,
	* src/processor.h:

2003-11-29  Scott Dattalo  <scott@dattalo.com>
	* src/pic-processor.cc - rewrote the way gpsim groups together all of
	the processors it supports. Now the ProcessorConstructor class will
	allow processors to be instantiated anywhere in the code (before, they
	were declared in one giant array.)

2003-11-29  Scott Dattalo  <scott@dattalo.com>
	* src/16bit-registers.cc - Access to PLUSWx are now signed.
	
2003-11-28  Scott Dattalo  <scott@dattalo.com>

	* src/cod.cc - Endian bug
	* gui/gui_processor.cc - use memset instead of bzero.
	
2003-09-14  Scott Dattalo  <scott@dattalo.com>
 	* src/gpsim_time.h - changed cycle counter break point from a Singly linked
	list to a doubly linked list. This is in preparation for separating module
	time from pic processor time so that when the PIC goes to sleep, time 
	doesn't stop.
	
2003-09-07  Scott Dattalo  <scott@dattalo.com>
	* src/p16f62x.h - duplicate declaration of intcon register
	
2003-09-07  Scott Dattalo  <scott@dattalo.com>
	* src/breakpoints.cc - this time the 'Too many cycle counter breakpoints' was
	fixed. BTW the problem was that 'clear_break' was not putting the cleared
	breakpoint back into the 'inactive' list
	
2003-09-07  Scott Dattalo  <scott@dattalo.com>
	* src/pic_processor.cc -- Fixed the "Too many cycle counter breakpoints" bug
	* src/interface.cc        It turns out that the "realtime" stuff was 
	* src/breakpoints.cc      1) duplicating a class declaration. 2) not clearing
	* src/breakpoints.h       cycle counter break points.
	* gpsim.sln - added for win32 port.
	
2003-08-30  Scott Dattalo  <scott@dattalo.com>
	* src/p12x.cc -- The 12c5xx will reset if an I/O is toggled and the processor
	is sleeping.

2003-08-27  Scott Dattalo  <scott@dattalo.com>
	* config_win32.h.in - added

2003-08-25  Scott Dattalo  <scott@dattalo.com>
	* src/ioports.cc - more 16f628 Port A fixes
	
2003-08-19  Scott Dattalo  <scott@dattalo.com>
	* eXdbm/parse.c - "char" is used to store result of fgetc, but
			EOF doesn't fit in the default unsigned chars.
	* src/cod.cc - an endian issue which made symbol values come out wrong.
		- note these fixes came from a patch attached to an anonymous  bug report
	
2003-08-18  Scott Dattalo  <scott@dattalo.com>
	* src/ioports.cc - Port A on the F62x devices was named "ioport"
	* src/p16f62x.cc - intcon was not declared at 0x8b (bug 566165)
	* regression/p16f628.asm  - Added a regression test for the f68
	* regression/p16f628.stc

2003-08-17  Scott Dattalo  <scott@dattalo.com>
	* regression/* started the regression test directory. Only two
	tests are performed: instruction validation for the midrange
	family and a simple node test.
	
2003-08-17  Scott Dattalo  <scott@dattalo.com>
	* Huge patch from Borut Razem mailto:borut.razem@siol.net that enables
	gpsim to be compiled with MS Visual C under Windows.

	
2003-06-19  Scott Dattalo  <scott@dattalo.com>

	* src/gpsim_time.h Multiple breaks at one Cycle were getting clobbered.
	* src/gpsim_time.cc

	* src/pic-processor.h add pll_scale for the 18f devices.
	
2003-05-25  Scott Dattalo  <scott@dattalo.com>

	* src/breakpoints.cc program memory break points were not working.
	* Started formatting the Changelog properly

	* Enhanced module interface - now LCD module works with gpsim
	* Patch from Rudy Moore to fix TMR0 bug
	* Beautified the Single Step and Trace dump outputs
	* Added break on stack overflow and underflow
	* Added break mask to wv/rv type break points. Now you can specify
	  which bits are significant.
	* Added "abort_gpsim_now" command. This will unconditionally abort gpsim.
	* Added "--cli" command line option. Invokes gpsim in command line 
	  mode even if it has been configured to use the gui.
	* Program viewer can now display ASCII encode text in "dt" tables
	* Symbolic setting of execution breaks was not working.
	* C++ bugs fixed
	* Fixed WDT during SLEEP bug reported by Tor Fredrik Aas mailto:tfa@abn.hibu.no
	* USART baud rates were generated incorrectly and have been fixed.
	* TXIF was handled improperly (reported by Wojciech Zabolotny <wzab@ise.pw.edu.pl>)
	* TMR1 was incrementing even when disabled (Reported by Wojciech)
	* Patch from JG for Suse 7.1. 
	* Patch from Robert Pearce to add 16C55
	* Sleep now works for 12c5xx.
	* Config word now works for 12c5xx
	* GPIO can wake a sleeping 12c5xx
	* Added pullup/pulldown resistors to the gpsim modules (idea from SET)
	* Numerous patches from from (SET) Salvador mailto:salvador@inti.gov.ar
	* SET - added "frequency" command
	* SET - Added time field to the gui status bar.
	* Carlos Nieves nega - Massive patch for the 17cxx core
	* Carlos Nieves nega - Registers for 17cxx core
	* From Salvador Eduardo Tropea mailto:salvador@inti.gov.ar
	  * Modified: In gpsim/main.cc put a cast in poptGetContext call, but perhaps
	    is a fault in the version I use of popt, double check it.
	  * Added: gtk_window_set_wmclass calls to help Enlightenment to remmember the
	   positions of the windows.     
	  * Added: In gui/gui_main.c a couple of #undef to avoid redefinitions in
	    eXdbm.h. Also check if that's OK for the eXdbm you are using.
	  * Modified: Moved the INTCON register from _14bit_18pins class to child
	    classes. That's because I needed to inherit from it and P16X6X_processor
	    and both defines INTCON. I also think things are more clear in this way.
	  * Fixed: A bug in the A/D routines. If you started a conversion at the same
	    time you were enabling the A/D this conversion was aborted. To fix it I
	    transfered new_value to value before calling start_conversion().
	  * Added: Partial support for 16C712 and 16C716 CPUs, they inherit from 14bits
	    18pins processors because they have 18 pins and also from 16x6x because
	    they have TMR1, TMR2 and Capture/Compare facilities like in 16C63. I could
	    check it deeply, just the A/D part. I also didn't implement the DATACCP and
	    TRISCCP registers, I don't know how they work, but I think they control the
	    use of some I/O pins (normal or CCP function).

03FEB00 gpsim-0.18.0
 o cli - added 'processor pins' command to display
         the state of a pic's I/O pins
 o cli - added 'set' command for modifying gpsim behavior
         flags. set options supported:
         -- verbose - if set, diagnostic info will be displayed
         -- radix - not supported yet
         -- gui_update - controls the rate at which the gui is refreshed
 o cli - added 's' option to the dump command to display only the
         special function registers (and not the rest of ram).
 o 18cxxx:
   -- TBLRD & TBLWT instructions are now supported
   -- MULLW & MULWF instructions are now supported
   -- configuration word support
   -- tmr0 interrupt

 o gui - added Watch window
 o gui - added more color coding to register window
 o gui - removed stagnant menu selections
 o gui - window state is saved between gpsim sessions
   -- This requires a new package `eXdbm'.
 o getopt is now used to process invocation options (now you can
   have spaces between the options and file names).
 o support >64k object code in .cod files
 o gtksheet has been removed from the distribution
   -- This means that you'll have to install gtk+-extra, the
      package that supports gtk-sheet (see INSTALL)
 o .cod file format bug fixes (you'll need the latest gpasm)
 o __config word for 18cxxx family is now supported 

16NOV99 gpsim-0.17.0

 o gui - Symbol window added
 o 18Cxxx
   -- Interrupts are now supported
   -- TMR0 is implemented
   -- USART asynchronous mode is supported
 o automake is now used to create the makefiles
 o version numbering has changed so that 'minor releases' (which by definition
   are the only ones I've made) are now expressed in the middle revision instead
   of the last revision number.
 o numerous bug fixes
 o Cycle counter is now 64 bits.


gpsim-0.0.16
 o 18Cxxx core has been added
 o Ralf Forsberg has joined me in development. His major contributions 
   have been in the gui code. Some of what he's done:
   - Wrote a new source browser with these features:
     -- Syntax highlighting (e.g. opcodes and comments are colored differently)
     -- Iconic indicators (e.g. bitmaps indicating breaks, current pc...)
     -- Multiple sources
   - Significant restructuring of the gpsim to gui interface


28JUL99 gpsim-0.0.15
 o gui - asm source browser
 o gui - program memory browser
 o gui - register viewer enhancements
 o gui - control menu
 o numerous bug fixes

30JUN99 gpsim-0.0.14
  o gui
  o numerous bug fixes

25APR99 gpsim-0.0.13
  o Split the command line interface from simulator
    - created a `src' directory for the simulator
    - created a `cli' directory for the command line interface
  o Re-wrote the cli to use bison and flex (whew - whatabitch)
  o Hi-Tech C-compiler .cod files can be loaded by gpsim now.
  o Fixed C++ errors that egcs abhored but gcc ignored.

08MAR99 gpsim-0.0.12
  o Added support for .cod files (mostly in cod.cc)
  o Added more symbolic debugging features
  o Added 'list' command for listing source files
  o Updated the 'load' command for loading .cod files
  o Repeat last command with carriage return
  o Added more documentation

10JAN99 gpsim-0.0.11
  o Added support for the PIC16C74
  o Fixed core dumps associated with the 12C50x (again, dammit)
  o Fundamentally changed the way registers are created.
  o Added a 'config' script

20DEC98 gpsim-0.0.10
  o Added support for the PIC16C71
  o Enhanced the asynchronous stimulus to support analog values
  o Added a triangle_wave stimulus (mainly for testing)
  o Changed the behavior of 'run' to ignore a breakpoint if there is one set
    at the current instruction (see below)
  o Added a few examples illustrating the use of analog stimuli

07DEC98 gpsim-0.0.9
  o Added support for the 12c508 and 12c509
  o Bug Fixes:
     - DC bit wasn't updated correctly in add's and sub's (if W was the destination)
     - stack was rolling over after 7 pushes
     - goto's and call's were limited to 10 bits
  o Added the command line option '-v' and the command version. Both echo 
    gpsim's version.
  o Enhanced 'it.asm' and added 'it_12bit.asm' - two routines that exercise
    gpsim's ability to simulate the pic instructions.
  o Added a trace for skipped instructions (before you'd see skipped instructions
    the same as non skipped ones in the trace buffer).


16NOV98 gpsim-0.0.8

  o added new file p16x6x
  o added support for the PIC16C61
  o began support for the PIC16C64
  o Changed the command line invocation: -p now selects a processor and not a core (e.g. -p14 used to be the way gp
sim liked to select a device within the midrange, 14-bit family; now you must specify the specific device you wish 
to simulate: -pp16c61 .)
  o Generally overhauled everything in anticipation of supporting the 12-bit core


30SEP98 gpsim-0.0.6
  o <CNTRL C> now can asynchronously halt the execution.
