Used by updated makelist and software list code. [Aaron Giles] Updated png2bdc and makelist tools to not leak memory and use more modern techniques (no more MAX_DRIVERS in makelist, for example). [Aaron Giles] Deprecated auto_strdup and removed all uses by way of caller-managed astrings and the software list rewrite. [Aaron Giles] Rewrote software list management: [Aaron Giles] * removed the notion of a software_list that is separate from a software_list_device; they are one and the same now * moved several functions into device_image_interface since they really didn't belong in the core software list class * lots of simplification as a result of the above changes Additional notes (no whatsnew): Moved definition of FPTR to osdcomm.h. Some changes happened in the OSD code to fix issues, especially regarding freeing arrays. SDL folks may need to fix up some of these. The following devices still are using tokens and should be modernized (I found them because they kept their token as void * and tried to delete it, which you can't): namco_52xx_device (mame/audio/namco52.c) namco_54xx_device (mame/audio/namco54.c) namco_06xx_device (mame/machine/namco06.c) namco_50xx_device (mame/machine/namco50.c) namco_51xx_device (mame/machine/namco51.c) namco_53xx_device (mame/machine/namco53.c) voodoo_device (emu/video/voodoo.c) mos6581_device (emu/sound/mos6581.c) aica_device (emu/sound/aica.c) scsp_device (emu/sound/scsp.c) dmadac_sound_device (emu/sound/dmadac.c) s3c2440_device (emu/machine/s3c2440.c) wd1770_device (emu/machine/wd17xx.c) latch8_device (emu/machine/latch8.c) duart68681_device (emu/machine/68681.c) s3c2400_device (emu/machine/s3c2400.c) s3c2410_device (emu/machine/s3c2410.c) strataflash_device (mess/machine/strata.c) hd63450_device (mess/machine/hd63450.c) tap_990_device (mess/machine/ti99/990_tap.c) omti8621_device (mess/machine/omti8621.c) vdt911_device (mess/video/911_vdt.c) apollo_graphics_15i (mess/video/apollo.c) asr733_device (mess/video/733_asr.c)
* Another round of auto_alloc_array conversions. Aaron Giles2014-02-201-31/+19

* QT Debugger: Adds trackpc command, allowing for a visual display of where the Andrew Gardner2013-04-201-0/+4
| | | | | | | | | | | | | | | | | | | | program counter has visited in the dasm windows. Run "help trackpc" in the debugger to see the options. [Andrew Gardner] Out of whatsnew: This isn't enabled by default because of how sloooow it is to disassemble each opcode when you want to compute its crc32. That can be sped up with lookup tables and the like. There's a good chance I should pull the 'clear tracks' argument into its own command, but it functions as-is. This can be added to the windows debugger with a simple change to the osd display code.

* Since nobody checks for NULLs anyway, make Aaron Giles2012-09-191-31/+31
| | | | | | | | | | | | 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 Giles2012-09-171-8/+8

* Add safe_pc() and safe_pcbase() methods to device_t. Aaron Giles2012-09-111-2/+2
| | | | | | Convert all cpu_get_pc() to safe_pc() and cpu_getpreviouspc() to safe_basepc(). Removed the old macros.
* Move devices into a proper hierarchy and handle naming Aaron Giles2012-01-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Collapsed device_config and device_t into one class. Updated all Aaron Giles2011-04-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Switch from m_machine to machine() everywhere. In some cases this Aaron Giles2011-04-181-8/+8
| | | | | | | | | | | meant adding a machine() accessor but it's worth it for consistency. This will allow future changes from reference to pointer to happen transparently for devices. [Aaron Giles] Simple S&R: m_machine( *[^ (!=;]) machine()\1
* BIG update. Aaron Giles2011-03-291-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 *)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | supporting cleaner implementations of drivers in the explicitly OO world. Expect a follow-on of several more changes to clean up from this one, which deliberately tried to avoid touching much driver code. Converted address_space to a class, and moved most members behind accessor methods, apart from space->machine and space->cpu. Removed external references to 8le/8be/16le/16be/32le/32be/64le/64be. All external access is now done via virtual functions read_byte()/read_word()/etc. Moved differentiation between the endianness and the bus width internal to memory.c, and also added a new axis to support small/large address spaces, which allows for faster lookups on spaces smaller than 18 bits. Provided methods for most global memory operations within the new address_space class. These will be bulk converted in a future update, but for now there are inline wrappers to hide this change from existing callers. Created new module delegate.h which implements C++ delegates in a form that works for MAME. Details are in the opening comment. Delegates allow member functions of certain classes to be used as callbacks, which will hopefully be the beginning of the end of fetching the driver_data field in most callbacks. All classes that host delegates must derive from bindable_object. Today, all devices and driver_data do implicitly via their base class. Defined delegates for read/write handlers. The new delegates are always passed an address_space reference, along with offset, data, and mask. Delegates can refer to methods either in the driver_data class or in a device class. To specify a callback in an address map, just use AM_READ_MEMBER(class, member). In fact, all existing AM_ macros that take read/write handlers can now accept delegates in their place. Delegates that are specified in an address map are proto-delegates which have no object; they are bound to their object when the corresponding address_space is created. Added machine->m_nonspecific_space which can be passed as the required address_space parameter to the new read/write methods in legacy situations where the space is not provided. Eventually this can go away but we will need it for a while yet. Added methods to the new address_space class to dynamically install delegates just like you can dynamically install handlers today. Delegates installed this way must be pre-bound to their object. Moved beathead's read/write handlers into members of beathead_state as an example of using the new delegates. This provides examples of both static (via an address_map) and dynamic (via install_handler calls) mapping using delegates. Added read/write member functions to okim6295_device as an example of using delegates to call devices. Updated audio/williams.c as a single example of calling the device via its member function callbacks. These will be bulk updated in a future update, and the old global callbacks removed. Changed the DIRECT_UPDATE_CALLBACKs into delegates as well. Updated all users to the new function format. Added methods on direct_read_data for configuring the parameters in a standard way to make the implementation clearer. Created a simple_list template container class for managing the common singly-linked lists we use all over in the project. Many other internal changes in memory.c, mostly involving restructuring the code into proper classes.

* Moved debugging structure away from CPUs only and attached to all Aaron Giles2010-07-061-4/+3
| | | | | | | | | | | | | | | | devices. Debugger now creates one for each device. C++-ified most debugger operations to hang off the debugging class, and updated most callers. This still needs a little cleanup, but it fixes most issues introduced when the CPUs were moved to their own devices. Got rid of cpu_count, cpu_first, cpu_next, etc. as they were badly broken. Also removed cpu_is_executing, cpu_is_suspended, cpu_get_local_time, and cpu_abort_timeslice. Some minor name changes: state_value() -> state() state_set_value() -> set_state()

Updated member variables to match new naming convention. Changed the running_machine to take a constructed machine_config object in the constructor, instead of creating one itself, for consistency.
