macro from the source code. All MAME builds now include
the debugger, and it is enabled/disabled exclusively by
the runtime command-line/ini settings. This is a minor
speed hit for now, but will be further optimized going
forward.
Changed the 'd' suffix in the makefile to apply to DEBUG
builds (versus DEBUGGER builds as it did before).
Changed machine->debug_mode to machine->debug_flags.
These flags now indicate several things, such as whether
debugging is enabled, whether CPU cores should call the
debugger on each instruction, and whether there are live
watchpoints on each address space.
Redesigned a significant portion of debugcpu.c around
the concept of maintaining these flags globally and a
similar, more complete set of flags internally for each
CPU. All previous functionality should work as designed
but should be more robust and faster to work with.
Added new debugger hooks for starting/stopping CPU
execution. This allows the debugger to decide whether
or not a given CPU needs to call the debugger on each
instruction during the coming timeslice.
Added new debugger hook for reporting exceptions.
Proper exception breakpoints are not yet implemented.
Added new module debugger.c which is where global
debugger functions live.
1. In the MIPS core:
- renamed struct mips3_config -> mips3_config
- updated all drivers to the new names
- removed MIPS3DRC_STRICT_COP0 flag, which is no longer used
- a few minor cleanups
2. In the CPU interface:
- added new 'intention' parameter to the translate callback to
indicate read/write/fetch access, user/supervisor mode, and
a flag for debugging
- updated all call sites to pass an appropriate value
- updated all CPU cores to the new prototype
3. In the UML:
- added new opcode SETC to set the carry flag from a source bit
- added new opcode BSWAP to swap bytes within a value
- updated C, x86, x64 back-ends to support the new opcodes
- updated disassembler to support the new opcodes
4. In the DRC frontend:
- fixed bug in handling edge case with the PC near the 0 or ~0
* Input ports are now maintained hierarchically. At the top
level are input ports, which contain a list of fields. Each
field represents one or more bits of the port. Certain fields
such as DIP switches and configuration switches contain a
list of settings, which can be selected. DIP switch fields
can also contain a list of DIP switch locations.
* Normalized behavior of port overrides (via PORT_INCLUDE or
by defining multiple overlapping bits). All fields within a
port are kept in strict increasing bit order, so altered DIP
switches are now kept in the appropriate order. This addresses
MAMETesters bug 01671.
* Live port state is now fully separate from configured
state. This is manifested in a similar way to devices, where
a const list of ports can be managed either offline or live.
Each port has a pointer to an opaque set of live state which
is NULL when offline or valid when live. Each port also has
a running_machine * which is also NULL when offline.
* Because of this new arrangement, the conversion from tokens
to a list of ports now requires reasonably complex memory
allocation, so these port lists must be explicitly allocated
and freed (they are not mantained by automatic resource
allocation).
* Custom and changed callbacks now take a pointer to a field
config instead of a running machine. This provides more
information about what field triggered the change notification.
The machine can be found by referenced field->port->machine.
* The inptport.c module has been cleaned up and many
ambiguities resolved. Most of this is internal, though it did
result in osd_customize_inputport_list() being changed to
osd_customize_input_type_list(). The parameter to this function
is now a linked list instead of an array, and the structures
referenced have been reorganized somewhat.
* Updated config.c to pass machine parameters to its callbacks.
* Updated validity checks, XML output, and UI system to handle
the new structures.
* Moved large table of default input settings to a separate
include file inpttype.h.
* Removed gross hacks in trackfld and hyperspt NVRAM. These
may be broken as a result.
Subject: Machine -> machine cleanups
This patch changes "Machine" to "machine", when the runnin-machine
parameter is already available. In some cases I could even remove the
dprecat.h.
I will look for some occurances where it can be easily changed and
afterward take a step at adding the running_machine parameter in a
few places.
All callers that used 0 for the screen number now use machine->primary_screen
As a gap meassure, Where necessary, create a parallel set of video_screen_*_scrnum functions that take scrnum
All callers that specified a specific screen number now call the *_scrnum versions
Changed game info screen and overlay UI to display the screen tag instead of screen number
suffixed with _func. Did this throughout the core and
drivers I was familiar with.
Fixed gcc compiler error with recent render.c changes.
gcc does not like explicit (int) casts on float or
double functions. This is fracking annoying and stupid,
but there you have it.
- Added a video_screen_register_vbl_cb() function for registering VBLANK callbanks
- Changed inptport.c and debugcpu.c to make use the VBLANK callbacks
- Added video_screen_get_time_until_vblank_start()
- CCPU and anything using cpu_scalebyfcount() are currently broken
- I did some fairly extensive testing, but this is a very signficant internal change,
so some things may have broke
a new compile-time define (ENABLE_DEBUGGER). This means that MAME_DEBUG no longer means
"enable debugger", it simply enables debugging features such as assertions and debug code
in drivers.
Also removed the various levels of opbase protection in memory.h and always just turned
on full bounds checking.
Fixed build break due to missing ampoker.lay -> ampoker2.lay renaming.
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
- removed years from copyright notices
- removed redundant (c) from copyright notices
- updated "the MAME Team" to be "Nicola Salmoria and the MAME Team"
