by preceding it with "0x". This allows F4 to work properly, for
example, on the 68000 stepping to address a6, which also happens
to be a register name.
This takes full pathname/filename to the font, and the name can have styles
appended as in Windows: [b] for bold, [i] for italic, [s] for strikethrough,
and [u] for underlined. Fonts are rendered at a size of 120 points and scaled
down by the core, which looks superb on high-res displays. (Liberation Sans
that comes with most recent distros looks really good).
Warning: Linux/BSD builds now require SDL_ttf 2.x. On Fedora the required
package names are "SDL_ttf" and "SDL_ttf-devel".
if it owns a given font (based on the name), and if it does, it is
responsible for generating bitmaps on the fly as characters are requested.
Added new option -uifont to specify the UI font. It can be set to a filename,
in which case a BDF font will be loaded. It can also be set to a font name
(assuming the OSD support is present), in which case the OSD font by that
name is used. The default value is 'default' which can be used by the OSD
to substitute a default font or by the OSD, which will default to ui.bdf
as before. In all cases, it falls back to the built-in font by default if
none of the previous options works.
On Windows, the OSD will default to Tahoma as the font name. Also on
Windows, font names can be specified with [b] to indicate bold or [i] to
indicate italic.
module osdepend.c with default empty implementations. Changed
mame_execute() and cli_execute() to accept a reference to an
osd_interface which is provided by the caller.
Updated SDL and Windows OSD to create an osd_interface-derived
class and moved their OSD callbacks to be members.
Added explicit control handler for the console. Ctrl+C/Ctrl+Break now
explicitly terminate the process forcefully, rather than unwinding
through the system in an unexpected state. Other console events
(exit, shutdown, logoff) request a graceful exit.
Moved -effect implementation out of OSD code and into core since
the implementations were identical across Windows/SDL and implemented
in the core itself.
Log: Added preliminary support for saving debugger window locations. [Andrew Gardner]
(Notes)
* I only save the values for the SDL debugger for now.
* There is no loading of these values yet, but if this patch is confirmed good,
loading should be relatively straightforward to add.
* There is a slight chance this might not compile on OSes other than linux.
I will be available via e-mail for the next 10 hours and will assist
with any compilation problems if they occur.
* The patch seems like the "right way" to do things, but if I am doing anything
suspect, please feel free to make suggestions and corrections.
The purpose of making it const before was to discourage direct tampering,
but private/protected does a better job of that now anyhow, and it is
annoying now.
s/const[ \t]+address_space\b/address_space/g;
Is basically what I did.
devices. Debugger now creates one for each device. C++-ified most
debugger operations to hang off the debugging class, and updated
most callers. This still needs a little cleanup, but it fixes most
issues introduced when the CPUs were moved to their own devices.
Got rid of cpu_count, cpu_first, cpu_next, etc. as they were badly
broken. Also removed cpu_is_executing, cpu_is_suspended,
cpu_get_local_time, and cpu_abort_timeslice.
Some minor name changes:
state_value() -> state()
state_set_value() -> set_state()
DECLARE_LEGACY_CPU_DEVICE and DEFINE_LEGACY_CPU_DEVICE. Changed CPUs
to be their own device types, rather than all of type CPU with a
special internal subtype. Note that as part of this process I removed
the CPU_ prefix from the ALL-CAPS device name, so CPU_Z80 is just
plain old Z80 now. This required changing a couple of names like
8080 to I8080 so that there was an alphabetic first character.
Added memory interfaces to the list of fast-access interfaces. To do
this properly I had to add a separate method to devices which is
called immediately after construction, when it is possible to perform
dynamic_casts on fully-constructed objects. (This is just internal,
no changes necessary to the devices themselves.)
Some additional notes:
* SH2 and SH4 had typedefs that conflicted with their CPU_-less names
so I bulk renamed to structures to sh2_state and sh4_state; RB, feel
free to choose alternate names if you don't like 'em
* SCSP was caught doing something to the 3rd indexed CPU. Since several
systems that use SCSP don't even have 3 CPUs, I had no idea what
this was supposed to do, so I changed to it reference "audiocpu"
assuming that stv was the assumed target. This is really gross and
should be a configuration parameter, not a hard-coded assumption.
* created dynamic_bind<> template class to handle dynamically binding to
optionally-supported functions
* wrapped stack walking code in a class
* wrapped symbol lookup code in a class
* added support for parsing objdump-produced symbol dumps which include
non-global functions for much better stack dumps and profiling in gcc builds
Also: modified makefile for win32 targets to automatically run objdump and
produce a .sym file if SYMBOLS is enabled.
- always available now, just specify -profile <n> to enable it
- supports stack walking to uniquely identify call chains; the <n> parameter
to the -profile option specifies how deep to go
- automatically turns off throttling and multithreading, and sets the number of
processors available to 1 (since we only sample the main thread)
- output now uses the common symbol lookup, which actually uses the PDB for
MSVC builds and gives excellent results (may eventually figure out how to
extract gcc symbols someday)
- the top 30 unique call chains are output
running_machine definition and implementation.
Moved global machine-level operations and accessors into methods on the
running_machine class. For the most part, this doesn't affect drivers
except for a few occasional bits:
mame_get_phase() == machine->phase()
add_reset_callback() == machine->add_notifier(MACHINE_NOTIFY_RESET, ...)
add_exit_callback() == machine->add_notifier(MACHINE_NOTIFY_EXIT, ...)
mame_get_base_datetime() == machine->base_datetime()
mame_get_current_datetime() == machine->current_datetime()
Cleaned up the region_info class, removing most global region accessors
except for memory_region() and memory_region_length(). Again, this doesn't
generally affect drivers.
this object which can be called multiple times to append new devices
after the initial machine configuration is set up. Updated member
variables to match new naming convention.
Changed the running_machine to take a constructed machine_config
object in the constructor, instead of creating one itself, for
consistency. Also added machine->total_colors() as a shortcut to
machine->config->m_total_colors.
the device_config constructor. In situations where the proper name is not
known at construction time, a generic name can be specified and then
overridden later once the configuration is complete.
like them, but it's a start. Split implementation of individual view
types out to separate files. Updated all callers.
Also:
* fixed okim6295 memory view
* changed emualloc to free resource pools from earliest to latest
so that early objects can safely clean up stuff they allocated

performance as a result of this change. Do not panic; report issues to the
list in the short term and I will look into them. There are probably also
some details I forgot to mention. Please ask questions if anything is not
clear.
NOTE: This is a major internal change to the way devices are handled in
MAME. There is a small impact on drivers, but the bulk of the changes are
to the devices themselves. Full documentation on the new device handling
is in progress at http://mamedev.org/devwiki/index.php/MAME_Device_Basics
Defined two new casting helpers: [Aaron Giles]
downcast<type>(value) should be used for safe and efficient downcasting
from a base class to a derived class. It wraps static_cast<> by adding
an assert that a matching dynamic_cast<> returns the same result in
debug builds.
crosscast<type>(value) should be used for safe casting from one type to
another in multiple inheritance scenarios. It compiles to a
dynamic_cast<> plus an assert on the result. Since it does not optimize
down to static_cast<>, you should prefer downcast<> over crosscast<>
when you can.
Redefined running_device to be a proper C++ class (now called device_t).
Same for device_config (still called device_config). All devices and
device_configs must now be derived from these base classes. This means
each device type now has a pair of its own unique classes that describe
the device. Drivers are encouraged to use the specific device types
instead of the generic running_device or device_t classes. Drivers that
have a state class defined in their header file are encouraged to use
initializers off the constructor to locate devices. [Aaron Giles]
Removed the following fields from the device and device configuration
classes as they never were necessary or provided any use: device class,
device family, source file, version, credits. [Aaron Giles]
Added templatized variant of machine->device() which performs a downcast
as part of the device fetch. Thus machine->device<timer_device>("timer")
will locate a device named "timer", downcast it to a timer_device, and
assert if the downcast fails. [Aaron Giles]
Removed most publically accessible members of running_device/device_t in
favor of inline accessor functions. The only remaining public member is
machine. Thus all references to device->type are now device->type(), etc.
[Aaron Giles]
Created a number of device interface classes which are designed to be mix-
ins for the device classes, providing specific extended functionality and
information. There are standard interface classes for sound, execution,
state, nvram, memory, and disassembly. Devices can opt into 0 or more of
these classes. [Aaron Giles]
Converted the classic CPU device to a standard device that uses the
execution, state, memory, and disassembly interfaces. Used this new class
(cpu_device) to implement the existing CPU device interface. In the future
it will be possible to convert each CPU core to its own device type, but
for now they are still all CPU devices with a cpu_type() that specifies
exactly which kind of CPU. [Aaron Giles]
Created a new header devlegcy.h which wraps the old device interface using
some special template classes. To use these with an existing device,
simply remove from the device header the DEVICE_GET_INFO() declaration and
the #define mapping the ALL_CAPS name to the DEVICE_GET_INFO. In their
place #include "devlegcy.h" and use the DECLARE_LEGACY_DEVICE() macro.
In addition, there is a DECLARE_LEGACY_SOUND_DEVICE() macro for wrapping
existing sound devices into new-style devices, and a
DECLARE_LEGACY_NVRAM_DEVICE() for wrapping NVRAM devices. Also moved the
token and inline_config members to the legacy device class, as these are
not used in modern devices. [Aaron Giles]
Converted the standard base devices (VIDEO_SCREEN, SPEAKER, and TIMER)
from legacy devices to the new C++ style. Also renamed VIDEO_SCREEN to
simply SCREEN. The various global functions that were previously used to
access information or modify the state of these devices are now replaced
by methods on the device classes. Specifically:
video_screen_configure() == screen->configure()
video_screen_set_visarea() == screen->set_visible_area()
video_screen_update_partial() == screen->update_partial()
video_screen_update_now() == screen->update_now()
video_screen_get_vpos() == screen->vpos()
video_screen_get_hpos() == screen->hpos()
video_screen_get_vblank() == screen->vblank()
video_screen_get_hblank() == screen->hblank()
video_screen_get_width() == screen->width()
video_screen_get_height() == screen->height()
video_screen_get_visible_area() == screen->visible_area()
video_screen_get_time_until_pos() == screen->time_until_pos()
video_screen_get_time_until_vblank_start() ==
screen->time_until_vblank_start()
video_screen_get_time_until_vblank_end() ==
screen->time_until_vblank_end()
video_screen_get_time_until_update() == screen->time_until_update()
video_screen_get_scan_period() == screen->scan_period()
video_screen_get_frame_period() == screen->frame_period()
video_screen_get_frame_number() == screen->frame_number()
timer_device_adjust_oneshot() == timer->adjust()
timer_device_adjust_periodic() == timer->adjust()
timer_device_reset() == timer->reset()
timer_device_enable() == timer->enable()
timer_device_enabled() == timer->enabled()
timer_device_get_param() == timer->param()
timer_device_set_param() == timer->set_param()
timer_device_get_ptr() == timer->get_ptr()
timer_device_set_ptr() == timer->set_ptr()
timer_device_timeelapsed() == timer->time_elapsed()
timer_device_timeleft() == timer->time_left()
timer_device_starttime() == timer->start_time()
timer_device_firetime() == timer->fire_time()
Updated all drivers that use the above functions to fetch the specific
device type (timer_device or screen_device) and call the appropriate
method. [Aaron Giles]
Changed machine->primary_screen and the 'screen' parameter to VIDEO_UPDATE
to specifically pass in a screen_device object. [Aaron Giles]
Defined a new custom interface for the Z80 daisy chain. This interface
behaves like the standard interfaces, and can be added to any device that
implements the Z80 daisy chain behavior. Converted all existing Z80 daisy
chain devices to new-style devices that inherit this interface.
[Aaron Giles]
Changed the way CPU state tables are built up. Previously, these were data
structures defined by a CPU core which described all the registers and how
to output them. This functionality is now part of the state interface and
is implemented via the device_state_entry class. Updated all CPU cores
which were using the old data structure to use the new form. The syntax is
currently awkward, but will be cleaner for CPUs that are native new
devices. [Aaron Giles]
Converted the okim6295 and eeprom devices to the new model. These were
necessary because they both require multiple interfaces to operate and it
didn't make sense to create legacy device templates for these single cases.
(okim6295 needs the sound interface and the memory interface, while eeprom
requires both the nvram and memory interfaces). [Aaron Giles]
Changed parameters in a few callback functions from pointers to references
in situations where they are guaranteed to never be NULL. [Aaron Giles]
Removed MDRV_CPU_FLAGS() which was only used for disabling a CPU. Changed
it to MDRV_DEVICE_DISABLE() instead. Updated drivers. [Aaron Giles]
Reorganized the token parsing for machine configurations. The core parsing
code knows how to create/replace/remove devices, but all device token
parsing is now handled in the device_config class, which in turn will make
use of any interface classes or device-specific token handling for custom
token processing. [Aaron Giles]
Moved many validity checks out of validity.c and into the device interface
classes. For example, address space validation is now part of the memory
interface class. [Aaron Giles]
Consolidated address space parameters (bus width, endianness, etc.) into
a single address_space_config class. Updated all code that queried for
address space parameters to use the new mechanism. [Aaron Giles]
While at it, I also associated ESC to Menu bar toggling when in newui (like many other emulators for Windows), given that user would quit MESS with File > Exit in the menu bar.
