Case insensitivity has been preserved for command names, CPU and region tags and certain symbolic parameters (as well as expressions, which were treated as case-insensitive in other contexts), but filenames and character constants are no longer automatically lowercased. * debugcmd.cpp, debugcon.cpp: Remove some superfluous c_str() calls * debugcmd.cpp: Remove local member referencing debugger_cpu, which is accessed only rarely since the console now tracks the visible CPU

* Debugger expression and memory access overhaul AJR2020-05-251-0/+1
| | | | | | | | | | | | | - Memory references in expressions no longer default to the console's visible CPU if no device name was specified, except when entered through the console itself. Expressions in view windows now use the context of the currently selected device instead. - The pcatmem debug command and similar qt mouseover function now produce an error message if the initial address translation fails. Related internal changes (nw) - The debugger_cpu class no longer interprets memory accesses. The existing routines have been moved into symbol_table (which used to invoke them as callbacks), and reimplemented in most other places. Thecode duplication is a bit messy, but could be potentially improved in the future with new utility classes. - The cheat engine no longer needs to hook into the debugger_cpu class or instantiate a dummy instance of it. - The inclusion of debug/express.h within emu.h has been undone. Some debugging structures now need unique_ptr to wrap the resulting incomplete classes; hopefully the performance impact of this is negligible. Another direct consequence is that the breakpoint, watchpoint and registerpoint classes are no longer inside device_debug and have their own source file. - The breakpoint list is now a std::multimap, using the addresses as keys to hopefully expedite lookup. - The visible CPU pointer has been removed from the debugger_cpu class, being now considered a property of the console instead. - Many minor bits of code have been simplified.

| | | | | | | | | | debug/express.cpp, debugcpu.cpp: General cleanup (nw) - Change default base from hardcoded macro to dynamic parameter for parsed_expression - Change symbol table parameters and variables to references or std::reference_wrapper - Remove the (unused) ability to construct a parsed_expression without a symbol table - Eliminate symbol_table &table and void *memory_param arguments from callbacks (superfluous now that std::function can bind everything necessary) - Eliminate globalref pointer from symbol_table - Add explicitly defaulted move constructor and move assignment operator

* debugger: add 'gp' command Sven Schnelle2018-11-061-0/+1
| | | | | | | | | | | | | | gp 'go privilege' starts execution until the privilege mode changes. This can be used to break on task switches. I.e on m68k, one could do: gp { ~sr & 0x2000 && crp_aptr == 0x1234567 } which would execute until the privilege mode changes to user mode and the CPU root pointer is 0x1234567. for cpu code, all that is needed to make this work is calling debugger_privilege_hook() when the execution level changes.

* Rewind feature and RAM savestates. vadosnaprimer2017-12-061-0/+1
| | | | | | | | | | | | | | This starts the work requested in #2398. How RAM states work. Implemented using util::vectorstream. Instead of dumping m_save.m_entry_list to file, it writes them as binary to vectorstream. Compression is not used, as it would slow down the process. The header is written as usual, also in binary. When a state is loaded, the savestate data gets binary-read from vectorstream. How rewind works. Rewind is optional, it can be turned off through MAME GUI while not running. Rewind capacity is available there too. Rewind step hotkey is available from the standard hotkey menu. In the debugger you have the "rewind" command ("rw" shortcut) that works the same as the hotkey. Every time you advance a frame (pause step), rewinder captures a RAM savestate of the frame you were at. It does the same when you do step into/over/out in the debugger. Every time it captures a new state (and when you unpause), it marks as invalid all its states that go after the current machine time, because input might change, so they are not relevant anymore. It keeps their buffers allocated though, for future use. When rewinder runs out of allowed amount of savestates it can have, it invalidates the first state in the list and tosses its unique_ptr to the end of the list, then it uses its buffer to capture a new state. When you hit the rewind step key, or use "rewind" command in the debugger, it loads a state that is immediately before the current machine time. Invalid states between valid ones are not allowed to appear, as that breaks rewinder integrity and causes problems. Rewinder keeps its own set of ram states as a vector of unique_ptr's. All rewinder operations and errors get reported using machine().popmessage().
* (nw) misc cleanup: start replacing auto_alloc_* with smart pointers, get Vas Crabb2017-12-011-8/+10
| | | | | rid of reference constants in the debugger in favour of capturing the value in the bind/lambda (less ugly casting)
* general cleanup: Vas Crabb2017-05-231-2/+0
| | | | | | | | | | | * move rarely-used output and pty interfaces out of emu.h * consolidate and de-duplicate forward declarations, also remove some obsolete ones * clean up more #include guard macros * scope down a few more things (nw) Everyone, please keep forward declarations for src/emu in src/emu/emufwd.h - this will make it far easier to keep them in sync with declarations than having them scattered through all the other files.
* C++-ification of debugger code (misc std::string/std::vector adoption mainly) Nathan Woods2017-03-031-73/+73
|
* Remove emu.h from headers (nw) Olivier Galibert2017-02-111-1/+0
| | | | | | | | | | | | 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.
* Created a new debugger command 'tracesym' Nathan Woods2017-01-151-0/+1

* BIG update. Aaron Giles2011-03-291-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 *)
* 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.

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]
* Correct a long-standing design flaw: device configuration state Aaron Giles2010-01-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Big debugger cleanup. Aaron Giles2008-12-031-2/+13
| | | | | | | | | | | | | | | | | | | | | | | 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.
* Debugger interfaces cleanup. Still more to do but this compiles and Aaron Giles2008-11-211-2/+3
| | | | | | | 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.
* Copyright cleanup: Aaron Giles2008-01-061-1/+1
