or ENDIANNESS_BIG based on the LSB_FIRST definition. Unlink LSB_FIRST,
ENDIANNESS_NATIVE always exists and can be used in expressions without
invoking the preprocessor.
Added macro ENDIAN_VALUE_LE_BE() which selects one of two values based
on the endianness passed in. Also added NATIVE_ENDIAN_VALUE_LE_BE()
which calls ENDIAN_VALUE_LE_BE with ENDIANNESS_NATIVE.
Updated a number of drivers and call sites to use these macros in favor
of #ifdef LSB_FIRST.

Intel i860 CPU core added. [Jason Eckhardt]
(The CPU core doesn't have accurate cycle counts for each opcode yet, but it'll have them soon. I believe that is the main culprit behind the sync of the two i860s and the 68k being outta' whack. You can still see the i860s do their thing and rasterize a voxel? groundplane and some simple polygon bad guys).

Subject: [patch] static/const/include fixes
Hi mamedev,
Here's my aperiodic code cleanup patch for MAME, adding static/const
and adjusting header files. In a few places I went a bit further.
1. arm7core.[ch],segas24.[ch]: Rewrote some abuses of the HANDLER
macros to use _func types instead.
2. m37710: Removed some long dead state save functions.
3. spc700: Removed the interface declarations and functions. Most of
it is handled by CPU_GET_INFO, some of it was no longer implemented,
and since pointerization it wasn't possible to call it externally
anyhow.
4. segac2: I removed the palette variables aliasing the megadrive ones
and just used the megadrive ones directly.
5. snes: All the obc1_, DSP1_, DSP2_ exports were made static. I'd
avoided doing this previously for fear it might break MESS, but after
auditing I'm fairly certain this shouldn't cause problems.

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()

during early initialization when the CPU cores generally need it.
Removed the dummy CPU core and cpuintrf.c.

Subject: [patch] Make Machine static!
Hi mamedev,
This large patch completes the removal of the use of Machine
throughout MAME. It does so primarily by adding machine, device or
space to various apis and modifying the callers, but for some
remaining cases it adds a new api, mame_get_running_machine(), which
will be called instead. There are only 14 uses of this api currently,
and that number should drop over time.
There are a few changes of note:
1. 6821pia.c. I attached machine to the 'device' structure. I'm
working on converting this to a proper device, but that change isn't
ready.
2. fddebug.c. I added a proper header so that the apis won't get
accidentally converted to static again.
3. scsi.c. I added a machine to SCSIInstance.
4. system16.c. I modified sys16_patch_code to take an array of
patches.
4. custom.h. I added the owning sound device to the reset/stop
routines as well as the token. Note that passing only the device
would require exposing the internals of custom_sound, as the token
passed is not the device token, but the token returned from the
CUSTOM_START routine. Better ideas here are welcome.
4. ppc2c0x.c. To avoid changing more interfaces, the init routine
saves the videorom location rather than looks it up each time.
I tried to choose what I felt was the natural parameter for an api,
rather than always pass machine, but in some cases I used machine to
limit the number of additional changes. Some additional cleanup here
is probably warranted, I'll look into that later once I'm recovered
from this two-week project.

interfaces when handling strings. Namely, the generic
get_info functions allocate a temporary string and the
device in question copies its string to the target,
instead of assigning a const char *. Updated all device
and sound cores to operate this way.
Added the concept of a cpu_state_table, which is
supplied by the CPU cores and which describes all the
register state accessible to the debugger and other
subsystems. The format of the table is such that most
data can be simply fetched from memory without the
further involvement of the CPU core, including the
display of common formats. Extensibility points are
available for custom display and for importing/exporting
the data to intermediate variables for more complicated
scenarios. Updated the ADSP21xx, TMS340x0, and i86 cores
to use this.
Removed the old debugger register list, which was never
used. Replaced it with using ordering from the
cpu_state_table.
Renamed REG_PC -> REG_GENPC, REG_SP -> REG_GENSP, and
REG_PREVIOUSPC -> REG_GENPCBASE. Updated a few spots
that were using these directly. Moved these definitions
into the end of the register area rather than leaving
them outside which put them in a weird range.
i86/i286/i386/nec/v30mz:
* renamed i86.h -> i86priv.h
* renamed i86intrf.h -> i86.h
* consolidated i88intrf.h, i186intf.h, i188intf.h, etc into i86.h
m6805:
* moved memory read/write macros out of public header
m37710:

specified when the device is added, and the clock is available in
the device_config directly via device->clock. Updated all devices
that have a clock to specify it when adding the device, rather than
as part of their configuration. As part of this work, also created
device-specific _ADD and _REMOVE macros to simplify configuration.
Dfined a generic device execute function callback, though it
is not used yet. The long term plan is that any device with an
execute callback will be scheduled along with the CPUs. Now that
CPUs are devices, their scheduling will be moved over to this
logic eventually.
Changed various NVRAM devices to fetch their default memory region
from the device->region rather than specifying it in the
configuration.
Moved a number of CPUINFO_PTR_* constants to CPUINFO_FCT_*.
Fixed several drivers that manually created their own gfx_elements
to fill in the machine object, so they no longer crash.
Fixed incorrect CPU display on info screen (recently broken).
Moved device startup to *before* the DRIVER_INIT is called. This
is to allow the DRIVER_INIT to configure devices that have been
properly allocated. So far I don't see any negative effects, but
be on the lookout if something weird shows up.
Rewrote the device iteration logic to make use of the typenext
field and the newly-introduced classnext field for iterating more
efficiently through devices of a given type or class.
Fixed behavior of MDRV_CPU_REPLACE so it does not delete and then
re-add a CPU (causing the order to change).

Change cpu_type from an enumeration into a pointer to the

For now all CPUs are declared in cpuintrf.h, but

file, and the driver should #include that header.
Added function cpu_get_type() to return the CPU type.
Changed several cpu_* functions into macros that call
through to the equivalent device_* function.
The device system now maintains a parallel list of devices
based on type, for faster iteration through all devices
of a given type.
Cleaned up code that looped over CPUs via the machine->cpu
array to now loop using the type-based device list.

Disabled the use of PULSE_LINE for any input lines except NMI and RESET.
Added a helper function generic_pulse_irq_line() for doing a single-cycle
assert/deassert for those few drivers remaining that were trying to use
PULSE_LINE directly.
This is a reworked/expanded version of the patch I sent yesterday.
This one is split into three parts:
1. This introduces function macros for SAMPLES_START,
CUSTOM_{START,STOP,RESET}, and ANTIC_RENDERER.
2. This introduces running_machine *machine throughout MAME.
Principally it adds running_machine *machine = Machine to the top of
functions, but in some static functions the parameter is added
directly. Some similar changes in 99xxcore.h, v9938.c, v9938mod.c,
galaxold.c, psx.c, taito_l.c are also made to eliminate Machine
params. No global API is changed.
3. This changes the APIs introduced in the first part to pass device
or space as appropriate. A few similar changes in some other global
apis are made as well.
The net result of this sequence of patches is to remove 40% of the
Machine references and 27 deprecat.h includes.

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.

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

to manually reset the CPU after making the change (since it
has already been reset).

The most common api coupling was with address maps in the CPU cores,
which this patch addresses by introducing a new macro,
ADDRESS_MAP_NAME (mimicing what is done in devintrf.h). There were a
handful of related problems in some drivers which this patch also
fixes. Some remaining issues I left alone (laserdisk apis reference
rom, video_update, machine_config, ksys573 use of nvram_handler,
megadriv use of ipt), in principle all the apis need _NAME variants to
encode the conventions.
