* Replace "const address_space" with "address_space" throughout the system. Aaron Giles2010-08-191-1/+1
| | | | | | | | | | | The purpose of making it const before was to discourage direct tampering, but private/protected does a better job of that now anyhow, and it is annoying now. s/const[ \t]+address_space\b/address_space/g; Is basically what I did.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Giles2010-07-061-40/+35
| | | | | | | | | | | | | | | | 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()
* Split mame.c into mame.c and machine.c, the latter containing the Aaron Giles2010-06-301-6/+6
| | | | | | | | | | | | | | | | | | | running_machine definition and implementation. Moved global machine-level operations and accessors into methods on the running_machine class. For the most part, this doesn't affect drivers except for a few occasional bits: mame_get_phase() == machine->phase() add_reset_callback() == machine->add_notifier(MACHINE_NOTIFY_RESET, ...) add_exit_callback() == machine->add_notifier(MACHINE_NOTIFY_EXIT, ...) mame_get_base_datetime() == machine->base_datetime() mame_get_current_datetime() == machine->current_datetime() Cleaned up the region_info class, removing most global region accessors except for memory_region() and memory_region_length(). Again, this doesn't generally affect drivers.
* C++-ified the debugger views. Not quite architecturally where I would Aaron Giles2010-06-251-3/+3
| | | | | | | | | | | like them, but it's a start. Split implementation of individual view types out to separate files. Updated all callers. Also: * fixed okim6295 memory view * changed emualloc to free resource pools from earliest to latest so that early objects can safely clean up stuff they allocated

Do not panic; report issues to the list in the short term and I will look into them. There are probably also some details I forgot to mention. Please ask questions if anything is not clear. NOTE: This is a major internal change to the way devices are handled in MAME. There is a small impact on drivers, but the bulk of the changes are to the devices themselves. Full documentation on the new device handling is in progress at http://mamedev.org/devwiki/index.php/MAME_Device_Basics Defined two new casting helpers: [Aaron Giles] downcast<type>(value) should be used for safe and efficient downcasting from a base class to a derived class. It wraps static_cast<> by adding an assert that a matching dynamic_cast<> returns the same result in debug builds. crosscast<type>(value) should be used for safe casting from one type to another in multiple inheritance scenarios. It compiles to a dynamic_cast<> plus an assert on the result. Since it does not optimize down to static_cast<>, you should prefer downcast<> over crosscast<> when you can. Redefined running_device to be a proper C++ class (now called device_t). Same for device_config (still called device_config). All devices and device_configs must now be derived from these base classes. This means each device type now has a pair of its own unique classes that describe the device. Drivers are encouraged to use the specific device types instead of the generic running_device or device_t classes. Drivers that have a state class defined in their header file are encouraged to use initializers off the constructor to locate devices. [Aaron Giles] Removed the following fields from the device and device configuration classes as they never were necessary or provided any use: device class, device family, source file, version, credits. [Aaron Giles] Added templatized variant of machine->device() which performs a downcast as part of the device fetch. Thus machine->device<timer_device>("timer") will locate a device named "timer", downcast it to a timer_device, and assert if the downcast fails. [Aaron Giles] Removed most publically accessible members of running_device/device_t in favor of inline accessor functions. The only remaining public member is machine. Thus all references to device->type are now device->type(), etc. [Aaron Giles] Created a number of device interface classes which are designed to be mix- ins for the device classes, providing specific extended functionality and information. There are standard interface classes for sound, execution, state, nvram, memory, and disassembly. Devices can opt into 0 or more of these classes. [Aaron Giles] Converted the classic CPU device to a standard device that uses the execution, state, memory, and disassembly interfaces. Used this new class (cpu_device) to implement the existing CPU device interface. In the future it will be possible to convert each CPU core to its own device type, but for now they are still all CPU devices with a cpu_type() that specifies exactly which kind of CPU. [Aaron Giles] Created a new header devlegcy.h which wraps the old device interface using some special template classes. To use these with an existing device, simply remove from the device header the DEVICE_GET_INFO() declaration and the #define mapping the ALL_CAPS name to the DEVICE_GET_INFO. In their place #include "devlegcy.h" and use the DECLARE_LEGACY_DEVICE() macro. In addition, there is a DECLARE_LEGACY_SOUND_DEVICE() macro for wrapping existing sound devices into new-style devices, and a DECLARE_LEGACY_NVRAM_DEVICE() for wrapping NVRAM devices. Also moved the token and inline_config members to the legacy device class, as these are not used in modern devices. [Aaron Giles] Converted the standard base devices (VIDEO_SCREEN, SPEAKER, and TIMER) from legacy devices to the new C++ style. Also renamed VIDEO_SCREEN to simply SCREEN. The various global functions that were previously used to access information or modify the state of these devices are now replaced by methods on the device classes. Specifically: video_screen_configure() == screen->configure() video_screen_set_visarea() == screen->set_visible_area() video_screen_update_partial() == screen->update_partial() video_screen_update_now() == screen->update_now() video_screen_get_vpos() == screen->vpos() video_screen_get_hpos() == screen->hpos() video_screen_get_vblank() == screen->vblank() video_screen_get_hblank() == screen->hblank() video_screen_get_width() == screen->width() video_screen_get_height() == screen->height() video_screen_get_visible_area() == screen->visible_area() video_screen_get_time_until_pos() == screen->time_until_pos() video_screen_get_time_until_vblank_start() == screen->time_until_vblank_start() video_screen_get_time_until_vblank_end() == screen->time_until_vblank_end() video_screen_get_time_until_update() == screen->time_until_update() video_screen_get_scan_period() == screen->scan_period() video_screen_get_frame_period() == screen->frame_period() video_screen_get_frame_number() == screen->frame_number() timer_device_adjust_oneshot() == timer->adjust() timer_device_adjust_periodic() == timer->adjust() timer_device_reset() == timer->reset() timer_device_enable() == timer->enable() timer_device_enabled() == timer->enabled() timer_device_get_param() == timer->param() timer_device_set_param() == timer->set_param() timer_device_get_ptr() == timer->get_ptr() timer_device_set_ptr() == timer->set_ptr() timer_device_timeelapsed() == timer->time_elapsed() timer_device_timeleft() == timer->time_left() timer_device_starttime() == timer->start_time() timer_device_firetime() == timer->fire_time() Updated all drivers that use the above functions to fetch the specific device type (timer_device or screen_device) and call the appropriate method. [Aaron Giles] Changed machine->primary_screen and the 'screen' parameter to VIDEO_UPDATE to specifically pass in a screen_device object. [Aaron Giles] Defined a new custom interface for the Z80 daisy chain. This interface behaves like the standard interfaces, and can be added to any device that implements the Z80 daisy chain behavior. Converted all existing Z80 daisy chain devices to new-style devices that inherit this interface. [Aaron Giles] Changed the way CPU state tables are built up. Previously, these were data structures defined by a CPU core which described all the registers and how to output them. This functionality is now part of the state interface and is implemented via the device_state_entry class. Updated all CPU cores which were using the old data structure to use the new form. The syntax is currently awkward, but will be cleaner for CPUs that are native new devices. [Aaron Giles] Converted the okim6295 and eeprom devices to the new model. These were necessary because they both require multiple interfaces to operate and it didn't make sense to create legacy device templates for these single cases. (okim6295 needs the sound interface and the memory interface, while eeprom requires both the nvram and memory interfaces). [Aaron Giles] Changed parameters in a few callback functions from pointers to references in situations where they are guaranteed to never be NULL. [Aaron Giles] Removed MDRV_CPU_FLAGS() which was only used for disabling a CPU. Changed it to MDRV_DEVICE_DISABLE() instead. Updated drivers. [Aaron Giles] Reorganized the token parsing for machine configurations. The core parsing code knows how to create/replace/remove devices, but all device token parsing is now handled in the device_config class, which in turn will make use of any interface classes or device-specific token handling for custom token processing. [Aaron Giles] Moved many validity checks out of validity.c and into the device interface classes. For example, address space validation is now part of the memory interface class. [Aaron Giles] Consolidated address space parameters (bus width, endianness, etc.) into a single address_space_config class. Updated all code that queried for address space parameters to use the new mechanism. [Aaron Giles]
* Made device->tag and devconfig->tag into private member variables (m_tag). Aaron Giles2010-03-081-1/+1
| | | | | | Added inline tag() function to return a const char * version. Updated callers to use this instead of directly accessing tag.cstr() which was awkward.
* Correct a long-standing design flaw: device configuration state Aaron Giles2010-01-181-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | is now separate from runtime device state. I have larger plans for devices, so there is some temporary scaffolding to hold everything together, but this first step does separate things out. There is a new class 'running_device' which represents the state of a live device. A list of these running_devices sits in machine->devicelist and is created when a running_machine is instantiated. To access the configuration state, use device->baseconfig() which returns a reference to the configuration. The list of running_devices in machine->devicelist has a 1:1 correspondance with the list of device configurations in machine->config->devicelist, and most navigation options work equally on either (scanning by class, type, etc.) For the most part, drivers will now deal with running_device objects instead of const device_config objects. In fact, in order to do this patch, I did the following global search & replace: const device_config -> running_device device->static_config -> device->baseconfig().static_config device->inline_config -> device->baseconfig().inline_config and then fixed up the compiler errors that fell out. Some specifics: Removed device_get_info_* functions and replaced them with methods called get_config_*. Added methods for get_runtime_* to access runtime state from the running_device. DEVICE_GET_INFO callbacks are only passed a device_config *. This means they have no access to the token or runtime state at all. For most cases this is fine. Added new DEVICE_GET_RUNTIME_INFO callback that is passed the running_device for accessing data that is live at runtime. In the future this will go away to make room for a cleaner mechanism. Cleaned up the handoff of memory regions from the memory subsystem to the devices.
* Within src/emu, basic conversions: Aaron Giles2010-01-121-1/+1
| | | | | | devtag_get_device ... machine->device() memory_find_address_space ... device->space()
* First round of an attempted cleanup of header files in the system. Aaron Giles2010-01-101-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Created new central header "emu.h"; this should be included by pretty much any driver or device as the first include. This file in turn includes pretty much everything a driver or device will need, minus any other devices it references. Note that emu.h should *never* be included by another header file. - Updated all files in the core (src/emu) to use emu.h. - Removed a ton of redundant and poorly-tracked header includes from within other header files. - Temporarily changed driver.h to map to emu.h until we update files outside of the core. Added class wrapper around tagmap so it can be directly included and accessed within objects that need it. Updated all users to embed tagmap objects and changed them to call through the class. Added nicer functions for finding devices, ports, and regions in a machine: machine->device("tag") -- return the named device, or NULL machine->port("tag") -- return the named port, or NULL machine->region("tag"[, &length[, &flags]]) -- return the named region and optionally its length and flags Made the device tag an astring. This required touching a lot of code that printed the device to explicitly fetch the C-string from it. (Thank you gcc for flagging that issue!)
* Extended the astring class wrapper into something useful, and Aaron Giles2010-01-081-8/+4
| | | | | | | | | | | | | | | | | | useable as a stack object. Also designed the interfaces to allow for chaining operations. And added a casting operator to const char * for seamless use in most functions that take plain old C strings. Changed all uses of astring to use the object directly on the stack or embedded in objects instead of explicitly allocating and deallocating it. Removed a lot of annoying memory management code as a result. Changed interfaces that accepted/returned an astring * to use an astring & instead. Removed auto_alloc_astring(machine). Use auto_alloc(machine, astring) instead.
* NOTE: This change requires two new osd functions: osd_malloc() and Aaron Giles2010-01-081-30/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | osd_free(). They take the same parameters as malloc() and free(). Renamed mamecore.h -> emucore.h. New C++-aware memory manager, implemented in emualloc.*. This is a simple manager that allows you to add any type of object to a resource pool. Most commonly, allocated objects are added, and so a set of allocation macros is provided to allow you to manage objects in a particular pool: pool_alloc(p, t) = allocate object of type 't' and add to pool 'p' pool_alloc_clear(p, t) = same as above, but clear the memory first pool_alloc_array(p, t, c) = allocate an array of 'c' objects of type 't' and add to pool 'p' pool_alloc_array_clear(p, t, c) = same, but with clearing pool_free(p, v) = free object 'v' and remove it from the pool Note that pool_alloc[_clear] is roughly equivalent to "new t" and pool_alloc_array[_clear] is roughly equivalent to "new t[c]". Also note that pool_free works for single objects and arrays. There is a single global_resource_pool defined which should be used for any global allocations. It has equivalent macros to the pool_* macros above that automatically target the global pool. In addition, the memory module defines global new/delete overrides that access file and line number parameters so that allocations can be tracked. Currently this tracking is only done if MAME_DEBUG is enabled. In debug builds, any unfreed memory will be printed at the end of the session. emualloc.h also has #defines to disable malloc/free/realloc/calloc. Since emualloc.h is included by emucore.h, this means pretty much all code within the emulator is forced to use the new allocators. Although straight new/delete do work, their use is discouraged, as any allocations made with them will not be tracked. Changed the familar auto_alloc_* macros to map to the resource pool model described above. The running_machine is now a class and contains a resource pool which is automatically destructed upon deletion. If you are a driver writer, all your allocations should be done with auto_alloc_*. Changed all drivers and files in the core using malloc/realloc or the old alloc_*_or_die macros to use (preferably) the auto_alloc_* macros instead, or the global_alloc_* macros if necessary. Added simple C++ wrappers for astring and bitmap_t, as these need proper constructors/destructors to be used for auto_alloc_astring and auto_alloc_bitmap. Removed references to the winalloc prefix file. Most of its functionality has moved into the core, save for the guard page allocations, which are now implemented in osd_alloc and osd_free.

* Bulk change alert. Aaron Giles2009-04-261-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This update changes the way we handle memory allocation. Rather than allocating in terms of bytes, allocations are now done in terms of objects. This is done via new set of macros that replace the malloc_or_die() macro: alloc_or_die(t) - allocate memory for an object of type 't' alloc_array_or_die(t,c) - allocate memory for an array of 'c' objects of type 't' alloc_clear_or_die(t) - same as alloc_or_die but memset's the memory to 0 alloc_array_clear_or_die(t,c) - same as alloc_array_or_die but memset's the memory to 0 All original callers of malloc_or_die have been updated to call these new macros. If you just need an array of bytes, you can use alloc_array_or_die(UINT8, numbytes). Made a similar change to the auto_* allocation macros. In addition, added 'machine' as a required parameter to the auto-allocation macros, as the resource pools will eventually be owned by the machine object. The new macros are: auto_alloc(m,t) - allocate memory for an object of type 't' auto_alloc_array(m,t,c) - allocate memory for an array of 'c' objects of type 't' auto_alloc_clear(m,t) - allocate and memset auto_alloc_array_clear(m,t,c) - allocate and memset All original calls or auto_malloc have been updated to use the new macros. In addition, auto_realloc(), auto_strdup(), auto_astring_alloc(), and auto_bitmap_alloc() have been updated to take a machine parameter. Changed validity check allocations to not rely on auto_alloc* anymore because they are not done in the context of a machine. One final change that is included is the removal of SMH_BANKn macros. Just use SMH_BANK(n) instead, which is what the previous macros mapped to anyhow.
* CPU interface organization shuffle. The file cpuintrf.h now merely Aaron Giles2008-12-221-1/+1
| | | | | | | | | | | | | | | | | | | describes the interface, but does not contain any implementation. All remaining bits of implementation have been migrated either to cpuexec.c or to debugcpu.c. Specifically, cpu_dasm() is now debug_cpu_disassemble(), and cpu_set_dasm_override() is now debug_cpu_set_dasm_override(). Also moved memory_address_physical() to debug_cpu_translate(), since it was only ever used for debugging. Changed all CPU and sound cores to use memory_find_address_space() instead of cpu_get_address_space(). The former is reliable even during early initialization when the CPU cores generally need it. Removed the dummy CPU core and cpuintrf.c. Changed the core execution loop to directly call the execute function instead of using the inline helper (which has been removed).

* More debugger changes. Aaron Giles2008-12-031-3/+3
| | | | | | | | | | | | | | | | | Added the concept of 'subviews' to the debugger views. The core now creates a list of possible subviews, and the OSD can select between them. This removes code from the OSD that was previously required to find all possible memory and disassembly views. Added machine parameters to debugger console output functions. Fixed some oddities in the memory view. Moved globals to hang off of the machine structure. Fixed bug where the visiblecpu was not updated immediately upon a break.
* Big debugger cleanup. Aaron Giles2008-12-031-3/+2
| | | | | | | | | | | | | | | | | | | | | | | Important note for OSD ports: the get/set property functions have been retired for debug_views. Instead, there are specific functions to perform each get/set operation. In addition, the format of the update callback has changed to pass the osd private data in, and the update callback/osd private data must be passed in at view allocation time. And osd_wait_for_debugger() now gets a CPU object instead of the machine. Removed extra debugger tracking for address spaces and added some of the useful data to the address_space structure. Updated all debugger commands and views to use CPU and address space objects where appropriate. Added new memory functions for converting between bytes and addresses, and for performing translations for a given address space. Removed debugger macros that did similar things in favor of calling these functions. Rewrote most of the memory view handling. Disasm and register views still need some additional tweaking.

* Further debugger cleanup. Symbol tables now have a global ref Aaron Giles2008-11-221-2/+3

* Debugger interfaces cleanup. Still more to do but this compiles and Aaron Giles2008-11-211-17/+21
| | | | | | | works. Added callback parameters to the expression engine. Improved CPU parsing so you can use a CPU tag or index in most commands that take one. Switched to passing CPU and address space objects around where appropriate. Lots of other minor tweaks.
* Another big one. Aaron Giles2008-11-201-2/+2
| | | | | | | | | | | | | | | | | | | | Moved memory global state into a struct hanging off of the machine. Updated almost all memory APIs to take an address_space * where appropriate, and updated all callers. Changed memory internals to use address spaces where appropriate. Changed accessors to point to the memory_* functions instead of the address space-specific functions. Improved internal handling of watchpoints. Added cputag_* functions: cputag_reset(), cputag_get_index(), cputag_get_address_space(). These just expand via macros to an initial fetch of the CPU via cputag_get_cpu() followed by the standard CPU call. Added debugger_interrupt_hook() and debugger_exception_hook() calls which intelligently look at the debugger flags before calling. Did minimal cleanup of debugger, mainly moving CPU-specific data to hang off of the CPU classdata for more direct access.
* Massive API cleanup/change. The primary goal is that all CPU- Aaron Giles2008-11-131-28/+36

All functions that take a CPU device are prefixed with cpu_* All functions that are globally related to cpu execution are prefixed with cpuexec_*. Below is a list of some of the mappings: cpu_boost_interleave -> cpuexec_boost_interleave cpunum_suspend -> cpu_suspend cpunum_resume -> cpu_resume cpunum_is_suspended -> cpu_is_suspended cpunum_get_clock -> cpu_get_clock cpunum_set_clock -> cpu_set_clock cpunum_get_clockscale -> cpu_get_clockscale cpunum_set_clockscale -> cpu_set_clockscale cpunum_get_localtime -> cpu_get_local_time cpunum_gettotalcycles -> cpu_get_total_cycles activecpu_eat_cycles -> cpu_eat_cycles activecpu_adjust_icount -> cpu_adjust_icount cpu_trigger -> cpuexec_trigger cpu_triggertime -> cpuexec_triggertime cpunum_set_input_line -> cpu_set_input_line cpunum_set_irq_callback -> cpu_set_irq_callback In addition, a number of functions retain the same name but now require a specific CPU parameter to be passed in: cpu_yield cpu_spin cpu_spinuntil_time cpu_spinuntil_int cpu_spinuntil_trigger cpu_triggerint Merged cpuint.c into cpuexec.c. One side-effect of this change is that driver reset callbacks are called AFTER the CPUs and devices are reset. This means that if you make changes to the CPU state and expect the reset vectors to recognize the changes in your reset routine, you will need to manually reset the CPU after making the change (since it has already been reset). Added a number of inline helper functions to cpuintrf.h for managing addresses Removed cpu_gettotalcpu(). This information is rarely needed outside of the core and can be obtained by looking at the machine->cpu[] array. Changed CPU interrupt acknowledge callbacks to pass a CPU device instead of machine/cpunum pair. Changed VBLANK and periodic timer callbacks to pass a CPU device instead of machine/cpunum pair. Renamed all information getters from cpu_* to cpu_get_* and from cputype_* to cputype_get_*.
* Major cpuintrf changes: Aaron Giles2008-11-101-4/+5
| | | | | | | | | | | | | | | | | | | | | | * added a set of cpu_* calls which accept a CPU device object; these are now the preferred means of manipulating a CPU * removed the cpunum_* calls; added an array of cpu[] to the running_machine object; converted all existing cpunum_* calls to cpu_* calls, pulling the CPU device object from the new array in the running_machine * removed the activecpu_* calls; added an activecpu member to the running_machine object; converted all existing activecpu_* calls to cpu_* calls, pulling the active CPU device object from the running_machine * changed cpuintrf_push_context() to cpu_push_context(), taking a CPU object pointer; changed cpuintrf_pop_context() to cpu_pop_context(); eventually these will go away * many other similar changes moving toward a model where all CPU references are done by the CPU object and not by index

| | | | | | | | | | | | | | | | | | | | | | | This contains three different patches: 20080829.patch Introducing the running_machine* parameter in a few more places. Next step would be to make the execute_* function aware of it, if that's OK. Also used the machine parameter in memory.c were it's available. 20080829_1.patch The already discussed and probably being rejected removal of dreprecat.h from debugger.h. I think this is a low-risk patch (we had worse cleanups) and it lowers the risk of new code using deprecated function beign introduced in MAME/MESS, because there is no invisible inclusion of deprecat.h anymore (I think one driver - kofball.c - got it with deprecated code). 20080829_2.patch The last Machine -> machine conversion I had sitting in my local tree. I know the proper way is to turn them into devices, but I still haven't looked into that.
* Fixes error: Andrew Gardner2008-02-031-6/+9
| | | | | pool_object_add (via src/emu/debug/debugcmt.c:107): Attempted to add a NULL object of size 0 This was happening when mame_debug_init was being called with 0 CPUs (eg. when starting MAME from the command line without a ROMset specified).
* - Added deprecat.h that contains some deprecated/discouraged contructs (see ↵ Zsolt Vasvari2008-01-251-0/+1
| | | | | | | | | below) The idea is to create extra work if a driver wants to use these and hopefully gives an incentive to look for an alternate solution - Added #include of deprecat.h that rely on these contructs - Removed a bunch of unneccassary #include's from these files
* Copyright cleanup: Aaron Giles2008-01-061-1/+1
| | | | | | - removed years from copyright notices - removed redundant (c) from copyright notices - updated "the MAME Team" to be "Nicola Salmoria and the MAME Team"
* (From Atari Ace) Aaron Giles2007-12-311-7/+2
| | | | | | | | The attached patch adjusts most conditional logging in MAME to use the idiom "do { if (VERBOSE) logerror x; } while (0)". This has the benefit that the compiler checks the syntax of the logging even in the case it will be eliminated, and in fact a number of cases here needed adjustments to compile because of this.
* Initial checkin of MAME 0.121.mame0121 Aaron Giles2007-12-171-0/+570
