* Since nobody checks for NULLs anyway, make Aaron Giles2012-09-191-30/+36
| | | | | | | | | | | | device_memory_interface::space() assert against NULL and return a reference, and pushed references throughout all address space usage in the system. Added a has_space() method to check for those rare case when it is ambiguous. [Aaron Giles] Also reinstated the generic space and added fatal error handlers if anyone tries to actually read/write from it.
* Memory handler normalization, part 2. Change legacy Aaron Giles2012-09-171-212/+192
| | | | | | | read/write handlers to take an address_space & instead of an address_space *. Also update pretty much all other functions to take a reference where appropriate. [Aaron Giles]
* First pass at modernizing struct definitions. Aaron Giles2012-09-151-2/+1

* In device_state_interface, rename state() to state_int() Aaron Giles2012-09-111-2/+2
| | | | | | | | | | | | | | | and set_state() to set_state_int() for consistency. Update all callers. Also add set_pc() helper and updated all callers to use that instead of set_state_int(STATE_GENPC) [Aaron Giles] Added device_t::state() method to get the state interface. Added redundant device_state_interface::state() method to catch redundant use of it. [Aaron Giles] Removed cpu_get_reg() and cpu_set_reg() macros in favor of using the above methods. [Aaron Giles]

* Changed device->subregion to device->memregion. Moved Aaron Giles2012-04-201-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | memory_region management into the memory manager instead of directly in the machine. Hid the global region method; now all regions must be looked up relative to a device. If you're a member function, you can just use memregion("tag") directly. If you're a global function or a device referencing global regions, use machine().root_device().memregion("tag") to look up regions relative to the root. S&R to convert all references: machine([()]*)\.region machine\1\.root_device\(\).subregion Then remove redundant machine().root_device() within src/mame: ([ \t])machine\(\)\.root_device\(\)\. \1 And use state->memregion() if we have a state variable present: (state *= *[^;]+driver_data[^}]+)([^ \t]*)machine[()]*\.root_device\(\)\. \1state-> Finally some cleanup: screen.state-> state-> device->state-> state-> space->state-> state-> And a few hand-tweaks.

* Move devices into a proper hierarchy and handle naming Aaron Giles2012-01-241-15/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and paths consistently for devices, I/O ports, memory regions, memory banks, and memory shares. [Aaron Giles] NOTE: there are likely regressions lurking here, mostly due to devices not being properly found. I have temporarily added more logging to -verbose to help understand what's going on. Please let me know ASAP if anything that is being actively worked on got broken. As before, the driver device is the root device and all other devices are owned by it. Previously all devices were kept in a single master list, and the hierarchy was purely logical. With this change, each device owns its own list of subdevices, and the hierarchy is explicitly manifest. This means when a device is removed, all of its subdevices are automatically removed as well. A side effect of this is that walking the device list is no longer simple. To address this, a new set of iterator classes is provided, which walks the device tree in a depth first manner. There is a general device_iterator class for walking all devices, plus templates for a device_type_iterator and a device_interface_iterator which are used to build iterators for identifying only devices of a given type or with a given interface. Typedefs for commonly-used cases (e.g., screen_device_iterator, memory_interface_iterator) are provided. Iterators can also provide counts, and can perform indexed lookups. All device name lookups are now done relative to another device. The maching_config and running_machine classes now have a root_device() method to get the root of the hierarchy. The existing machine->device("name") is now equivalent to machine->root_device().subdevice("name"). A proper and normalized device path structure is now supported. Device names that start with a colon are treated as absolute paths from the root device. Device names can also use a caret (^) to refer to the owning device. Querying the device's tag() returns the device's full path from the root. A new method basetag() returns just the final tag. The new pathing system is built on top of the device_t::subtag() method, so anyone using that will automatically support the new pathing rules. Each device has its own internal map to cache successful lookups so that subsequent lookups should be very fast. Updated every place I could find that referenced devices, memory regions, I/O ports, memory banks and memory shares to leverage subtag/subdevice (or siblingtag/siblingdevice which are built on top). Removed the device_list class, as it doesn't apply any more. Moved some of its methods into running_machine instead. Simplified the device callback system since the new pathing can describe all of the special-case devices that were previously handled manually. Changed the core output function callbacks to be delegates. Completely rewrote the validity checking mechanism. The validity checker is now a proper C++ class, and temporarily takes over the error and warning outputs. All errors and warnings are collected during a session, and then output in a consistent manner, with an explicit driver and source file listed for each one, as well as additional device and/or I/O port contexts where appropriate. Validity checkers should no longer explicitly output this information, just the error, assuming that the context is provided. Rewrote the software_list_device as a modern device, getting rid of the software_list_config abstraction and simplifying things. Changed the way FLAC compiles so that it works like other external libraries, and also compiles successfully for MSVC builds.

* Switch to using delegates for some callbacks: Aaron Giles2011-04-271-4/+4
| | | | | | | | | | | | - non-device timer callbacks - machine state changing callbacks - configuration callbacks - per-screen VBLANK callbacks - DRC backend callbacks For the timer case only, I added wrappers for the old-style functions. Over time, drivers should switch to device timers instead, reducing the number of timers that are directly allocated through the scheduler.
* Collapsed device_config and device_t into one class. Updated all Aaron Giles2011-04-271-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | existing modern devices and the legacy wrappers to work in this environment. This in general greatly simplifies writing a modern device. [Aaron Giles] General notes: * some more cleanup probably needs to happen behind this change, but I needed to get it in before the next device modernization or import from MESS :) * new template function device_creator which automatically defines the static function that creates the device; use this instead of creating a static_alloc_device_config function * added device_stop() method which is called at around the time the previous device_t's destructor was called; if you auto_free anything, do it here because the machine is gone when the destructor is called * changed the static_set_* calls to pass a device_t & instead of a device_config * * for many devices, the static config structure member names over- lapped the device's names for devcb_* functions; in these cases the members in the interface were renamed to have a _cb suffix * changed the driver_enumerator to only cache 100 machine_configs because caching them all took a ton of memory; fortunately this implementation detail is completely hidden behind the driver_enumerator interface * got rid of the macros for creating derived classes; doing it manually is now clean enough that it isn't worth hiding the details in a macro

* Remove redundant item cpu from address_space, in favor of Aaron Giles2011-03-291-12/+12
| | | | | | | | | | | space->device(). S: space->cpu-> R: space->device\(\)\. S: space->cpu R: \&space->device\(\)
* BIG update. Aaron Giles2011-03-291-129/+129
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove redundant machine items from address_space and device_t. Neither machine nor m_machine are directly accessible anymore. Instead a new getter machine() is available which returns a machine reference. So: space->machine->xxx ==> space->machine().xxx device->machine->yyy ==> device->machine().yyy Globally changed all running_machine pointers to running_machine references. Any function/method that takes a running_machine takes it as a required parameter (1 or 2 exceptions). Being consistent here gets rid of a lot of odd &machine or *machine, but it does mean a very large bulk change across the project. Structs which have a running_machine * now have that variable renamed to m_machine, and now have a shiny new machine() method that works like the space and device methods above. Since most of these are things that should eventually be devices anyway, consider this a step in that direction. 98% of the update was done with regex searches. The changes are architected such that the compiler will catch the remaining errors: // find things that use an embedded machine directly and replace // with a machine() getter call S: ->machine-> R: ->machine\(\)\. // do the same if via a reference S: \.machine-> R: \.machine\(\)\. // convert function parameters to running_machine & S: running_machine \*machine([^;]) R: running_machine \&machine\1 // replace machine-> with machine. S: machine-> R: machine\. // replace &machine() with machine() S: \&([()->a-z0-9_]+machine\(\)) R: \1 // sanity check: look for this used as a cast (running_machine &) // and change to this: *(running_machine *)
* Cleanup of machine.h. Shuffled some fields around, and moved several Aaron Giles2011-03-281-2/+2
| | | | | | | | | | | | | to private member variables with accessors: machine->m_respool ==> machine->respool() machine->config ==> machine->config() machine->gamedrv ==> machine->system() machine->m_regionlist ==> machine->first_region() machine->sample_rate ==> machine->sample_rate() Also converted internal lists to use simple_list.
* Created new enum type address_spacenum for specifying an address Aaron Giles2011-03-271-19/+28
| | | | | | | | | | | | space by index. Update functions and methods that accepted an address space index to take an address_spacenum instead. Note that this means you can't use a raw integer in ADDRESS_SPACE macros, so instead of 0 use the enumerated AS_0. Standardized the project on the shortened constants AS_* over the older ADDRESS_SPACE_*. Removed the latter to prevent confusion. Also centralized the location of these definitions to memory.h.
* Added device_t::memory() to fetch a reference to the memory interface, Aaron Giles2011-03-271-17/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | or assert if not present. Split address_space::install_[legacy_]handler into install_[legacy_]read_handler, install_[legacy_]write_handler, and install_[legacy_]readwrite_handler. Added variants of address_space handler installers which don't take mirror or mask parameters, since this is by far the most common case. Deprecated API cleanup. Simple search & replace: cpu_suspend ==> device_suspend cpu_resume ==> device_resume cpu_yield ==> device_yield cpu_spin ==> device_spin cpu_spinuntil_trigger ==> device_spin_until_trigger cpu_spinuntil_time ==> device_spin_until_time cpu_spinuntil_int ==> device_spin_until_interrupt cpu_eat_cycles ==> device_eat_cycles cpu_adjust_icount ==> device_adjust_icount cpu_triggerint ==> device_triggerint cpu_set_input_line ==> device_set_input_line cpu_set_input_line_vector ==> device_set_input_line_vector cpu_set_input_line_and_vector ==> device_set_input_line_and_vector cpu_set_irq_callback ==> device_set_irq_callback More complex changes: device_memory(device) ==> device->memory() device_get_space(device, spacenum) ==> device->memory().space(spacenum) cpu_get_address_space(cpu, spacenum) ==> cpu->memory().space(spacenum) cputag_get_address_space(mach, tag, spacenum) ==> mach->device("tag")->memory().space(spacenum) cputag_get_clock(mach, tag) ==> mach->device("tag")->unscaled_clock() cputag_set_clock(mach, tag, hz) ==> mach->device("tag")->set_unscaled_clock(hz) Some regex'es for the more prevalent cases above: S: cpu_get_address_space( *)\(( *)([^,]+)( *), * R: \3->memory().space\1\(\2 S: cputag_get_address_space( *)\(( *)([^,]+)( *),( *)([^,]+)( *), * R: \3->device\1\(\2\6\7\)->memory().space\1\(\2 S: cputag_get_clock( *)\(( *)([^,]+)( *),( *)([^ )]+) *\) R: \3->device\1\(\2\6\7\)->unscaled_clock\(\)
* Converted core_options to a class. Removed a bunch of marginal Aaron Giles2011-03-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | functionality in favor of alternate mechanisms. Errors are now reported via an astring rather than via callbacks. Every option must now specify a type (command, integer, float, string, boolean, etc). Command behavior has changed so that only one command is permitted. [Aaron Giles] Changed fileio system to accept just a raw searchpath instead of an options/option name combination. [Aaron Giles] Created emu_options class dervied from core_options which wraps core emulator options. Added mechanisms to cleanly change the system name and add/remove system-specific options, versus the old way using callbacks. Also added read accessors for all the options, to ensure consistency in how parameters are handled. Changed most core systems to access emu_options instead of core_options. Also changed machine->options() to return emu_options. [Aaron Giles] Created cli_options class derived from emu_options which adds the command-line specific options. Updated clifront code to leverage the new class and the new core behaviors. cli_execute() now accepts a cli_options object when called. [Aaron Giles] Updated both SDL and Windows to have their own options classes, derived from cli_options, which add the OSD-specific options on top of everything else. Added accessors for all the options so that queries are strongly typed and simplified. [Aaron Giles] Out of whatsnew: I've surely screwed up some stuff, though I have smoke tested a bunch of things. Let me know if you hit anything odd. Also I know this change will impact the WINUI stuff, please let me know if there are issues. All the functionality necessary should still be present. If it's not obvious, please talk to me before adding stuff to the core_options class.
* mame_file is now emu_file and is a class. It is required Aaron Giles2011-02-121-14/+6
| | | | | | | | | | | | | | | | | | | | | | | | to pass a core_options object to the constructor, along with a search path. This required pushing either a running_machine or a core_options through some code that wasn't previously ready to handle it. emu_files can be reused over multiple open/close sessions, and a lot of core code cleaned up nicely as things were converted to them. Also created a file_enumerator class for iterating over files in a searchpath. This replaces the old mame_openpath functions. Changed machine->options() to return a reference. Removed public nvram_open() and fixed jchan/kaneko16 to stop directly saving NVRAM. Removed most of the mame_options() calls; this will soon go away entirely, so don't add any more. Added core_options to device_validity_check() so they can be used to validate things.

| | | | | | | | | | | | | | | | | Also replace timer_get_time() with machine->time() 1. Main conversion timer_get_time( *)\( *([^)]+) *\) \2->time\1() 2. Cleanup #1 &machine->time machine.time 3. Cleanup #2 &m_machine->time m_machine.time
* Attotime bulk conversion step: Aaron Giles2011-02-031-2/+2
| | | | | | | | | | | | | | | | | | attotime_zero => attotime::zero attotime_never => attotime::never ATTOTIME_IN_SEC(s) => attotime::from_seconds(s) ATTOTIME_IN_MSEC(m) => attotime::from_msec(m) ATTOTIME_IN_USEC(u) => attotime::from_usec(u) ATTOTIME_IN_NSEC(n) => attotime::from_nsec(n) ATTOTIME_IN_HZ(h) => attotime::from_hz(h) Also, changed the following MCFG macros to require a full attotime specification: MCFG_TIMER_ADD_PERIODIC MCFG_QUANTUM_TIME MCFG_WATCHDOG_TIME_INIT
* Converted attotime to a class, with proper operators. Removed old Aaron Giles2011-02-031-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | global functions which are now superceded by the operators and methods on the class. [Aaron Giles] Required mappings are: attotime_make(a,b) => attotime(a,b) attotime_to_double(t) => t.as_double() double_to_attotime(d) => attotime::from_double(d) attotime_to_attoseconds(t) => t.as_attoseconds() attotime_to_ticks(t,f) => t.as_ticks(f) ticks_to_attotime(t,f) => attotime::from_ticks(t,f) attotime_add(a,b) => a + b attotime_add_attoseconds(a,b) => a + attotime(0, b) attotime_sub(a,b) => a - b attotime_sub_attoseconds(a,b) => a - attotime(0, b) attotime_compare(a,b) == 0 => a == b attotime_compare(a,b) != 0 => a != b attotime_compare(a,b) < 0 => a < b attotime_compare(a,b) <= 0 => a <= b attotime_compare(a,b) > 0 => a > b attotime_compare(a,b) >= 0 => a >= b attotime_mul(a,f) => a * f attotime_div(a,f) => a / f attotime_min(a,b) => min(a,b) attotime_max(a,b) => max(a,b) attotime_is_never(t) => t.is_never() attotime_string(t,p) => t.as_string(p) In addition, some existing #defines still exist but will go away: attotime_zero => attotime::zero attotime_never => attotime::never ATTOTIME_IN_SEC(s) => attotime::from_seconds(s) ATTOTIME_IN_MSEC(m) => attotime::from_msec(m) ATTOTIME_IN_USEC(u) => attotime::from_usec(u) ATTOTIME_IN_NSEC(n) => attotime::from_nsec(n) ATTOTIME_IN_HZ(h) => attotime::from_hz(h)
* NetBSD support [Thomas Klausner] R. Belmont2011-02-021-1/+1
| | | | | | | | | Not for whatsnew: I added -Wno-conversion unconditionally to disable the warnings Thomas reported. That setting is the default for GCC out-of-the-box but apparently not on NetBSD. As far as I know it shouldn't cause a problem with any GCC version back to at least 4.0.0 so we're safe even on PPC OSX, but do let me know if hilarity ensues.
* C++-ified the sound and streams interfaces. Combined sound.c and streams.c Aaron Giles2011-01-271-2/+2
| | | | | | | | | | | | | | | | | | | into one file, and separated the speaker device into its own file. Generalized the concept of dynamically assigned inputs and re-wired the speaker to work this way, so it is now treated just like any other sound device. Added methods to the device_sound_interface for controlling output gain and mapping device inputs/outputs to stream inputs/outputs. Also made the sound_stream_update() method pure virtual, so all modern sound devices must use the new mechanism for stream updates. Primary changes outside of the core are: stream_update(stream) == stream->update() stream_create(device,...) == machine->sound().stream_alloc(*device,...) sound_global_enable(machine,enable) == machine->sound().system_enable(enable) Beyond this, the patterns are relatively obvious for the remaining calls.
* SDL OS/2 fixes [K.O. Myung-Hun] R. Belmont2011-01-101-1/+1

* Ok, last major rename for this round: Aaron Giles2011-01-011-3/+3
| | | | | | | | | | | | | | | | memory_region() == machine->region()->base() memory_region_length() == machine->region()->bytes() region_info -> memory_region Regex searches: S: memory_region( *)\(( *)([^,&]+), *([^)]+)\) R: \3->region\1\(\2\4\)->base\(\) S: memory_region_length( *)\(( *)([^,&]+), *([^)]+)\) R: \3->region\1\(\2\4\)->bytes\(\)
* Add directxor parameter to direct memory accessors. Update all callers Aaron Giles2010-12-311-13/+14
| | | | | | | | | that manually XORed addresses to pass the XOR instead. This improves behavior when direct accessors hit non-RAM regions, or when watchpoints are used, because we now know the original, un-xored address and can fall back to standard read/write handlers properly. Also fixes glitched disassembly when read watchpoints are enabled.
* Fixed BSD compile [ElBarto] R. Belmont2010-12-061-1/+3

* Split the screen device into a separate module. Aaron Giles2010-12-021-1/+1
| | | | | Converted global video routines into a video_manager. Moved video manager initialization earlier in startup.

* Converted the expression engine to C++, did the usual cleanup. Aaron Giles2010-11-011-155/+90
|
* Create new class osd_interface to house OSD callbacks. Added new Aaron Giles2010-10-211-16/+17
| | | | | | | | | module osdepend.c with default empty implementations. Changed mame_execute() and cli_execute() to accept a reference to an osd_interface which is provided by the caller. Updated SDL and Windows OSD to create an osd_interface-derived class and moved their OSD callbacks to be members.
* Converted render.c objects into C++ objects. Updated all callers. Aaron Giles2010-10-131-7/+7

* Cleanups and version bump.mame0139u3 Aaron Giles2010-09-191-14/+14

* Integrated comments into debugcpu.c, and removed debugcmt.c. Modernized Aaron Giles2010-09-051-8/+364
| | | | the code and updated so it actually works with the modern debug classes.
* Have each device create its own device_debug instead of letting the Aaron Giles2010-09-041-6/+15
| | | | | | | debugger do it. This allows the device to start itself up before the debugger tries to figure out what to do with it. Fixes the problem where register names were not populated into the symbol table correctly after I shuffled the initialization order.
* Since previous fix made lot of issues, found better solution for this ↵ Miodrag Milanovic2010-08-221-1/+1
| | | | astring bool problem (no whatsnew)
* Added bool operator to astring, returning true if the string is Aaron Giles2010-08-211-3/+3
| | | | | | not empty. Conveniently, this creates ambiguity if you write astring == NULL. Rooted out remaining cases where we were doing that and fixed them.
* Remove final set of legacy inlines from memory.h. Mostly affects CPU Aaron Giles2010-08-191-9/+9
| | | | | cores, which all now cache a copy of space->direct() and use it for direct accesses.
