* Various optimisations to code generaton. Vas Crabb2023-03-261-6/+5
| | | | | | | | | | | | | | | util/bitmap.cpp, util/palette.cpp: Marked lots of things constexpr. Bitmaps don't throw exceptions on allocation failure, they just become invalid. Almost nothing in MAME actually checks for this. emu/profiler.cpp: Abort if the profile stack overflows rather than throwing an exception. This is a developer feature and if it overflows, the code is broken. Calling a noreturn noexcept function generates less code than throwing an exception, which adds up. util/strformat.cpp: Traded away some unnecessary flexibility for more compact code. The stream objects must derive from std::basic_ostream now - they can't just be any old objects with the expected operators.

* bus/ISA: Added HP82321A BASIC Language coprocessor (#10926) Sven Schnelle2023-03-241-0/+5
| | | | | | | * emu: add defer_access() method, which is useful for keeping the cpu in a loop restarting the current instruction to emulate waitstates. * add HP82321A Basic Language Coprocessor This adds support for the HP82321A Basic language coprocessor, which emulates a HP9816 system with a 68K cpu. See http://www.hpmuseum.net/display_item.php?hw=681 for more details and software to run on this card.

* Move static data out of devices into the device types. This is a ↵ Vas Crabb2017-05-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Introduce u8/u16/u32/u64/s8/s16/s32/s64 Vas Crabb2016-11-191-1/+1
| | | | | | | | | | | | * 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
* NOTICE (TYPE NAME CONSOLIDATION) Miodrag Milanovic2016-10-221-1/+1
| | | | | 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
* Revert software-installed slot/image options when changing software AJR2016-04-041-1/+24
| | | | | - Remove emu.h's stealth include of emuopts.h through mconfig.h; reduce dependency on emuopts.h in other headers and source files. - MCFG_CPU_FORCE_NO_DRC is now a CPU configuration parameter rather than a global one; it still works to override the -drc option setting.
