working on something, hold off syncing.
Defined macros for core CPU functions: CPU_INIT, CPU_RESET, CPU_EXIT,
CPU_EXECUTE, along with macros for the name and for calling, in the
spirit of the devintrf.h macros. More will come later.
Changed init, reset, exit, and execute interfaces to be passed a
const device_config * object. This is a fake object for the moment,
but encapsulates the machine pointer and token. Eventually this will
be a real device.
Changed the CPU IRQ callbacks to a proper type, and added a device
parameter to them.
Updated all CPU cores to the new macros and parameters.
Note that this changes the way we "pointer"-ify cores. I'll send an
update shortly.
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.
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.
- Styling changes
- Added instruction cycle counts.
- Added interrupt support.
- Added HALT support.
- Fixed INT instruction.
- Added incomplete support for DIV and MUL instructions.
- Fixed MOV [#nnnn],BA and MOV [#nnnn],HL instructions.
Subject: [patch] Remove more Machine globals, #include "deprecat.h"
Hi mamedev,
The attached patch goes through and converts a number of Machine
globals to machine locals, and then removes #include "deprecat.h" if
appropriate. The script that generated it is included, since the
patch itself is rather large and would have been time consuming to
produce otherwise.
The script doesn't convert cases of Machine that aren't in common
macros. I'll try to tackle those later if someone doesn't beat me to
it.

src/emu/cpu/m68000/m68kmame.c:
src/emu/cpu/minx/minx.c:
- Fixed compilation errors on CPU cores not enabled in MAME
src/emu/inptport.c:
src/emu/inptport.h:
- Readded input_port_set_digital_value() (which is needed for natural
keyboard inpout in MESS)
- Added a running_machine parameter to inputx_update()
Subject: [patch] CPU/SOUND independence fixes
Hi mamedev,
Here's some updates to the CPU/SOUND cores to improve build
independence. While I was at it, I rescued the M65CE02 core from
bitrot hell (perhaps m65ce02.[ch] should just be deleted), and fixed
some MESS cores that were broken by the deprecat.h changes.
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.
Updated all CPU cores to return a CPUINFO_INT_CLOCK_MULTIPLIER of 1.
Changed the core to actually respect both CPUINFO_INT_CLOCK_MULTIPLIER and CPUINFO_INT_CLOCK_DIVIDER.
Updated a number of drivers to use cpunum_get_clock() instead of Machine->drv->cpu[x].clock.
***** Raw input clock speeds should now be specified for all CPUs in the MACHINE_DRIVER. *****
Removed explicit divisors from all drivers using the following CPU types,
which were already specifying non-1 values for CPUINFO_INT_CLOCK_DIVIDER:
* COP4x0
* I8039/8048 families
* M68(7)05, HD63705
* M6809E
* PIC16C5X
* TMS32010
* TMS340x0
In a few cases, it appears that the divisor was not being used, so I guessed in those cases whether or not
the specified clock speed was raw.
- removed years from copyright notices
- removed redundant (c) from copyright notices
- updated "the MAME Team" to be "Nicola Salmoria and the MAME Team"
This small patch makes some minor "code quality" improvements to MAME.
First off, some remaing static/const qualifier missed cases were
addressed. Secondly, a few cases of missing #include "foo.h" were
added. Thirdly, a few global names were modified to make them less
generic/more consistent (voodoo.c, vrender0.c, lethal.c, rungun.c,
zac2650.c). Fourthly, some dead/useless code was removed
(i8051.c,model1.c,romcmp.c).
