* misc: remove "all rights reserved" copyright comment, hap2025-01-222-3/+0
| | | | mcs51: remove old changelog from comments, remove copypasted comment block
* Demote tautological-compare to a warning again. Vas Crabb2024-11-271-3/+3
| | | | | | | clang on Windows x86-64 is getting upset about code that is making no assumptions about the relative sizes of uint64_t and long. Also, fixed more #include guards.
* dynax/dynax.cpp: Added DIP switches that are sometimes populated to Ougon no ↵ Vas Crabb2024-11-271-3/+4
| | | | | | Pai. Also fixed a bunch more #include guards.
* diexec: Add callback to allow debugger to break into the middle of wait-type ↵ AJR2024-11-171-0/+1
| | | | | | | | | | instructions whose execution time is normally indefinite. When this happens, a special message may be printed to the debug console stating the location of the last actual instruction executed before the wait (if there was one). Note that since the callback ignores the current value of the program counter, this special type of debugger break cannot be entered through breakpoints or instruction stepping commands. The callback also leaves no effect on PC history tracking or trace logs. * cpu/hd61700, cpu/tms32031: Add standard IRQ callback * cpu/m68000gen.py: Change name of invoked executable to bin/python3 * cpu/m6809: Eliminate PC "massaging" for SYNC and similar instructions
* Added ATTR_COLD to common lifecycle methods for many files in src/devices. ↵ holub2024-09-271-2/+2

* Debugger feature improvements AJR2022-03-271-0/+2
| | | | | | | | - Add 'gbt' and 'gbf' debugger commands to step until a true or false conditional branch has been detected. - Update over 100 of the disassemblers in MAME to output a new STEP_COND flag for all conditional branches. Besides being used for execution of the new 'gbt' and 'gbf' commands, this flag also now helps the debugger 'out' command to properly handle conditional return instructions. - Remove STEP_OVER from many instructions that aren't actually subroutine calls (e.g. DJNZ on Z80). A 'gni' debugger command (go next instruction) has been added to accommodate some of the misuse. - Add instruction flag support to several more disassemblers that lacked them entirely (e.g. st62xx) - Don't pass over delay slots for debugging in ASAP core
* Remove a few outdated references to MESS Dirk Best2021-12-021-7/+0

* Debugger-related feature removals and cleanup AJR2021-08-151-5/+0
| | | | | | | | - Remove the hotspot read tracker. This was never robustly implemented, but changes to the memory system made it much less useful, and the "speedup opportunities" which it aimed to determine are not very important from a current emulation standpoint. - Remove the CURSP/GENSP state symbol and the generic sp() getter. Stacking semantics vary too much between CPU architectures for this to be of much use. (A "SP" symbol has been added to a few CPU cores whose stack pointers were otherwise not being registered.) - Remove the cached pointer to device_state_interface and the state() fast accessor from device_t. Most users of device_state_interface either already had a pointer to the specific CPU device type or needed to check first for the presence of the interface. - Change the PC memory write tracker to use pcbase(), which works even when the instruction callback is masked out, instead of peeking at the PC history index. - Remove some obsolete watchpoint-related definitions from machine.h.

* Split S-SMP and S-DSP implement in snes_snd.cpp (#6417) cam9002020-04-042-4/+11
| | | | | | | | * Split S-SMP and S-DSP implement in snes_snd.cpp both convert memory handler into device_memory_interface, Internalize ROM region of S-SMP s_smp.cpp : Use callback for S-DSP interface, Split internal and external memory space snes.cpp : Convert WRAM into shared_ptr * s_dsp.cpp : Reduce #define macros
* Update spc700.cpp David Viens2020-02-011-6/+8
| | | | | | | | OP_TCLR1 and OP_TSET1 Tested fix as suggested here https://mametesters.org/view.php?id=5409 This makes Blargg's CPU_tset_tclr pass (from spc_smp.sfc) Removed page crossing penalty on EA_DIY Doing so allowed some of our internal S-SMP/S-DSP tests to pass

| | | | | Resolve MT06901 and MT07419 Also it fixes other games like Cliffhanger, Taekwon-Do and Super Tekkyuu Fight
* diexec: Interrupt API changes (nw) AJR2018-05-181-0/+1
| | | | | | - PULSE_LINE is no longer a value. Existing uses have been changed to pulse_input_line with attotime::zero as the second argument. - Formerly only INPUT_LINE_NMI and INPUT_LINE_RESET were allowed with PULSE_LINE. INPUT_LINE_NMI no longer receives special handling; instead, CPU devices must specify which of their input lines are edge-triggered and thus may be used with zero-width pulses by overriding the execute_input_edge_triggered predicate. INPUT_LINE_RESET is still special-cased, however. - execute_default_irq_vector now allows a different default vector to be specified for each input line. This added flexibility may or may not prove useful.

* dvdisasm: Overhaul [O. Galibert] Olivier Galibert2017-11-264-82/+88
| | | | | | | | 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 Crabb2017-05-142-11/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Self-registering devices prep: Vas Crabb2017-02-271-1/+1
| | | | | | | | | | | | | | * 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.
