| | | | | | | suddenly silenced * streamline templates in addrmap.h * get rid of overloads on read/write member names - this will become even more important in the near future
* Make MCFG_DEVICE_ADD and callable device types more flexible: Vas Crabb2018-05-042-0/+5
| | | | | | | | | | | | | | | | | | | | | * Allows defaulted clocks (see subtle example with vboy) * Allows additional constructors (see RS232 port in tranz330) * Allows use of device finder in place of tag in MCFG_DEVICE_ADD * Requires out-of-line destructor for devices using incomplete types * Requires XTAL or explicit u32 for clocks for devices with private types Devices must still define the standard constructor. When writing additional constructors, be aware that the constructor runs before device_add_mconfig in the context of the existing device, not the new device. See osborne1, zorba, tranz330, and vboy for examples of this in use. Compilation is a bit slower, but this is temporary while refactoring is in progress. Eliminated the need for MCFG_SOUND_ROUTE_EX. Removed macros from slot option configuration - they just obfuscated code and slowed it down with needless dynamic casts, but didn't actually simplify it.

* emumem: API change [O. Galibert] Olivier Galibert2017-11-293-14/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * direct_read_data is now a template which takes the address bus shift as a parameter. * address_space::direct<shift>() is now a template method that takes the shift as a parameter and returns a pointer instead of a reference * the address to give to {read|write}_* on address_space or direct_read_data is now the address one wants to access Longer explanation: Up until now, the {read|write}_* methods required the caller to give the byte offset instead of the actual address. That's the same on byte-addressing CPUs, e.g. the ones everyone knows, but it's different on the word/long/quad addressing ones (tms, sharc, etc...) or the bit-addressing one (tms340x0). Changing that required templatizing the direct access interface on the bus addressing granularity, historically called address bus shift. Also, since everybody was taking the address of the reference returned by direct(), and structurally didn't have much choice in the matter, it got changed to return a pointer directly. Longest historical explanation: In a cpu core, the hottest memory access, by far, is the opcode fetching. It's also an access with very good locality (doesn't move much, tends to stay in the same rom/ram zone even when jumping around, tends not to hit handlers), which makes efficient caching worthwhile (as in, 30-50% faster core iirc on something like the 6502, but that was 20 years ago and a number of things changed since then). In fact, opcode fetching was, in the distant past, just an array lookup indexed by pc on an offset pointer, which was updated on branches. It didn't stay that way because more elaborate access is often needed (handlers, banking with instructions crossing a bank...) but it still ends up with a frontend of "if the address is still in the current range read from pointer+address otherwise do the slowpath", e.g. two usually correctly predicted branches plus the read most of the time. Then the >8 bits cpus arrived. That was ok, it just required to do the add to a u8 *, then convert to a u16/u32 * and do the read. At the asm level, it was all identical except for the final read, and read_byte/word/long being separate there was no test (and associated overhead) added in the path. Then the word-addressing CPUs arrived with, iirc, the tms cpus used in atari games. They require, to read from the pointer, to shift the address, either explicitely, or implicitely through indexing a u16 *. There were three possibilities: 1- create a new read_* method for each size and granularity. That amounts to a lot of copy/paste in the end, and functions with identical prototypes so the compiler can't detect you're using the wrong one. 2- put a variable shift in the read path. That was too expensive especially since the most critical cpus are byte-addressing (68000 at the time was the key). Having bit-adressing cpus which means the shift can either be right or left depending on the variable makes things even worse. 3- require the caller to do the shift himself when needed. The last solution was chosen, and starting that day the address was a byte offset and not the real address. Which is, actually, quite surprising when writing a new cpu core or, worse, when using the read/write methods from the driver code. But since then, C++ happened. And, in particular, templates with non-type parameters. Suddendly, solution 1 can be done without the copy/paste and with different types allowing to detect (at runtime, but systematically and at startup) if you got it wrong, while still generating optimal code. So it was time to switch to that solution and makes the address parameter sane again. Especially since it makes mucking in the rest of the memory subsystem code a lot more understandable.
* dvdisasm: Overhaul [O. Galibert] Olivier Galibert2017-11-265-453/+455
| | | | | | | | Disassemblers are now independant classes. Not only the code is cleaner, but unidasm has access to all the cpu cores again. The interface to the disassembly method has changed from byte buffers to objects that give a result to read methods. This also adds support for lfsr and/or paged PCs.

* Move static data out of devices into the device types. This is a ↵ Vas Crabb2017-05-142-71/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | significant change, so please pay attention. 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.

This helps catch headers that don't #include things that they use.
