Also, look Ma - no magic prologue!
Slot card additions run in the context of the slot itself, which isn't
entirely intuitive. Slot configuration needs a bunch of other cleanup
anyway.
Concrete device types now have a call operator that instantiates a
device.
This change means you *must* use DECLARE_DEVICE_TYPE to declare the
public interface of your device, even if it's device_t. If you want
to use private implementation classes, use DEFINE_DEVICE_TYPE_PRIVATE
and instantiate the object finders.
The core changes are:
* Short name, full name and source file are no longer members of device_t, they are part of the device type
* MACHINE_COFIG_START no longer needs a driver class
* MACHINE_CONFIG_DERIVED_CLASS is no longer necessary
* Specify the state class you want in the GAME/COMP/CONS line
* The compiler will work out the base class where the driver init member is declared
* There is one static device type object per driver rather than one per machine configuration
Use DECLARE_DEVICE_TYPE or DECLARE_DEVICE_TYPE_NS to declare device type.
* DECLARE_DEVICE_TYPE forward-declares teh device type and class, and declares extern object finders.
* DECLARE_DEVICE_TYPE_NS is for devices classes in namespaces - it doesn't forward-declare the device type.
Use DEFINE_DEVICE_TYPE or DEFINE_DEVICE_TYPE_NS to define device types.
* These macros declare storage for the static data, and instantiate the device type and device finder templates.
The rest of the changes are mostly just moving stuff out of headers that shouldn't be there, renaming stuff for consistency, and scoping stuff down where appropriate.
Things I've actually messed with substantially:
* More descriptive names for a lot of devices
* Untangled the fantasy sound from the driver state, which necessitates breaking up sound/flip writes
* Changed DECO BSMT2000 ready callback into a device delegate
* Untangled Microprose 3D noise from driver state
* Used object finders for CoCo multipak, KC85 D002, and Irem sound subdevices
* Started to get TI-99 stuff out of the TI-990 directory and arrange bus devices properly
* Started to break out common parts of Samsung ARM SoC devices
* Turned some of FM, SID, SCSP DSP, EPIC12 and Voodoo cores into something resmbling C++
* Tried to make Z180 table allocation/setup a bit safer
* Converted generic keyboard/terminal to not use WRITE8 - space/offset aren't relevant
* Dynamically allocate generic terminal buffer so derived devices (e.g. teleprinter) can specify size
* Imporved encapsulation of Z80DART channels
* Refactored the SPC7110 bit table generator loop to make it more readable
* Added wrappers for SNES PPU operations so members can be made protected
* Factored out some boilerplate for YM chips with PSG
* toaplan2 gfx
* stic/intv resolution
* Video System video
* Out Run/Y-board sprite alignment
* GIC video hookup
* Amstrad CPC ROM box members
* IQ151 ROM cart region
* MSX cart IRQ callback resolution time
* SMS passthrough control devices starting subslots
I've smoke-tested several drivers, but I've probably missed something. Things I've missed will likely blow up spectacularly with failure to bind errors and the like. Let me know if there's more subtle breakage (could have happened in FM or Voodoo).
And can everyone please, please try to keep stuff clean. In particular, please stop polluting the global namespace. Keep things out of headers that don't need to be there, and use things that can be scoped down rather than macros.
It feels like an uphill battle trying to get this stuff under control while more of it's added.
- Have set_unscaled_clock and set_clock_scale not call notify_clock_changed unless the device has been started.
- Owner-derived clocks are now updated whenever the owner's clock is changed, including at configuration time. This simplifies the configuration of various NES clones.
- Add clock_update_delegate type to represent device-generated clock outputs that may be dynamically modified. The model implementation of this is the CLK output in I8085A.
* MAME now walks all devices when generating -lx output irrespective of whether they're actually instantiated anywhere or not.
* -lx is at least 30% faster than previous implementation.
* Only possible drawback is that filtering drivers no longer filters devices.
* Make device_creator a variable template and get rid of the ampersands
* Remove screen.h and speaker.h from emu.h and add where necessary
* Centralise instantiations of screen and speaker finder templates
* Add/standardise #include guards in many hearers
* Remove many redundant #includes
* Order #includesr to help catch headers that can't be #included alone
(nw) This changes #include order to be prefix, unit header if applicable
then other stuff roughly in order from most dependent to least dependent
library. This helps catch headers that don't #include things that they
use.
* New abbreviated types are in osd and util namespaces, and also in global namespace for things that #include "emu.h"
* Get rid of import of cstdint types to global namespace (C99 does this anyway)
* Remove the cstdint types from everything in emu
* Get rid of U64/S64 macros
* Fix a bug in dps16 caused by incorrect use of macro
* Fix debugcon not checking for "do " prefix case-insensitively
* Fix a lot of messed up tabulation
* More constexpr
* Fix up many __names
Use standard uint64_t, uint32_t, uint16_t or uint8_t instead of UINT64, UINT32, UINT16 or UINT8
also use standard int64_t, int32_t, int16_t or int8_t instead of INT64, INT32, INT16 or INT8
* Eliminate a lot of boilerplate code from devfind.h
* Keep instantiation of templates in one place to improve build time
* Remove some dangerous accessors
to unpack tiny_rom_entry structures at runtime.
WARNING - I've done preliminary testing on a tiny build (pacman works), but nothing more. I know for a fact that a full compile fails
Rewrite or remove every last instance of MCFG_DEVICE_CONFIG and its two aliases, including within comments and dead code.
Make the Z80/Z180 daisy chain an interface that interfaces with the existing interface. Z8000 has been hooked up to this as well (p8000_16 already configures it), but currently does nothing with it.
- Eliminate the cached device_t::m_region pointer and its region() getter method. Devices that need to bind to a region with the same tag should use optional/required_memory_region or optional/required_region_ptr with DEVICE_SELF as the subtag; this improves error checking. (DEVICE_SELF has been moved to device.h for greater visibility in the source.)
- Allow required/optional_region_ptr to specify a specific length which must match that of the region found.
- Implement finder_base::finder_tag() getter for diagnostic purposes.
- Perform some (not very efficient) validity checks on memory region finders instead of allowing them to automatically pass.
- Privatize device_memory_interface::m_addrspace.
C++11 range-based for loops can now iterate over simple_list, tagged_list, core_options, device_t::subdevice_list, device_t::interface_list, render_primitive_list and all subclasses of the above, and much code has been refactored to use them. Most core classes that have these lists as members now have methods that return the lists themselves, replacing most of the methods that returned the object at an owned list's head. (A few have been retained due to their use in drivers or OSD.)
device_t now manages subdevice and interface lists through subclasses, but has given up the work of adding and removing subdevices to machine_config.
memory_manager has its tagged lists exposed, though the old rooted tag lookup methods have been removed (they were privatized already).
* Make stream_format return characters printed

* Remove now-unnecessary I64FMT from calls to logerror/popmessage
* Put some lib/util stuff in util:: namespace
* Some fixes to Japanese translation
