* i86: don't clear physical irq pins state at reset hap2024-12-211-9/+5

* 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
* emu/devcb.h: Eliminated the need to call resolve() on callbacks. (#11333) Vas Crabb2023-06-171-1/+0
| | | | | | | | | | | | Read callbacks now need a default return value supplied at construction. Replaced isnull() with isunset() which tells you if the callback wasn't configured rather than whether it isn't safe to call. Enabled validation of device callbacks (it seems it was disabled at some point, probably accidentally). Device callbacks and object finders now implement the same interface for resolution.
* m6801: add i/o ports tri-state callback, hap2023-06-161-1/+1
| | | | misc: correct some typos
* emu/devdelegate.h: Added resolve_safe and resolve_all_safe helpers. Vas Crabb2023-06-131-1/+4
| | | | | | | | | Uses decay rules, so if a delegate returns a reference and you want to supply a referene to an object you don't want copied as the default result, remember to use std::ref. Updated a few devices to use resolve_safe on device delegates to streamline code.

| | | | divtlb: Wrap the constants
* Interrupt callback rationalization AJR2023-03-111-1/+1
| | | | | | | | | | | - Make CPUs pass interrupt return PC as a second argument to standard_irq_callback - Add interrupt return PC to "Stopped at interrupt" message produced by debugger 'gint' command - Add messages to trace logs whenever interrupts are accepted - Attempt to step over interrupt routines for applicable debugger commands - Eliminate standard_irq_callback_member wrapper method - Update many CPU cores to invoke standard_irq_callback at the start of or during interrupt processing, rather than at the end or when the input line changes - Remove IRQ callbacks for some input lines that never cause interrupts - mb88xx, mcs48: Add IRQ callbacks for internal interrupts

* Enable GCC implicit fallthrough warning. Vas Crabb2020-11-151-1/+2
| | | | | | I've guessed whether break or [[fallthrough]] is appropriate. In cases where it looked particularly suspicious, I added a FIXME comment. All of these changes should be reviewed by someone familiar with the code.

| | | | mb86235.cpp: renamed pcs_ptr into pcp, and added a file for future interpreter core (nw)
* i86: Memory stuff (nw) AJR2018-02-041-11/+0
| | | | | | | | - Make read_byte/word and write_byte/word overridable virtual functions (80186 MMU probably will need to override this in the future) - Make fetch_op an alias for fetch (implementations were identical already) - Remove sreg argument from read_byte/word and write_byte/word (it was almost always m_easeg as set by calc_addr, sometimes with dubious evaluation order) - Restrict logic for separating address spaces for CS/ES/SS accesses to 8086/8088 (later x86 models do not broadcast the descriptors) - Encapsulate m_e16 within the only function that used it

* This is too contentious, please put it up for review Vas Crabb2017-08-011-2/+2
| | | | | | Revert "Changes to debugger memory address translation" This reverts commit bb0964f9a284b15851773f5428bd602ca01cc28b.
* Changes to debugger memory address translation AJR2017-08-011-2/+2
| | | | | | - memory_translate now returns an address space number rather a boolean flag, permitting addresses in part of one space to map to an entirely different space. This is primarily intended to help MCUs which have blocks of internal memory that can be dynamically remapped, but may also allow for more accurate emulation of MMUs that drive multiple external address spaces, since the old limit of four address spaces per MAME device has been lifted. - memory_translate has also been made a const method, in spite of a couple of badly behaved CPU cores that can't honestly treat it as one. - The (read|write)_(byte|word|dword|qword|memory|opcode) accessors have been transferred from debugger_cpu to device_memory_interface, with somewhat modified arguments corresponding to the translate function it calls through to if requested.

* 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.

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

* Remove emu.h from headers (nw) Olivier Galibert2017-02-111-0/+1
| | | | | | | | | | | | Per Vas' request. If the compile fails for you (i'm thinking osx and windows native debuggers here in particular), add '#include "emu.h"' as first include of the cpp files that fail. Due to our use of precompilation and forced inclusion, emu.h must be included as the very first non-comment thing we do if we want to be sure msvc compiles are identical to gcc/clang ones. Doing it directly instead of through an include increases the correctness probability by a magnitude.
