integers. This is defined to be "I64" on MSVC and recent mingw compilers,
and "ll" for all others.
Updated all instances of 64-bit prints to use the new macro.
Changed bilinear filter to use faster rgbutil.h version. It would
be even faster if the texture code downconverted to fixed-point
earlier and then used the integer values when doing the texture
lookups.

Subject: MAME Debugger
In some processors (like Z80), it is not possible to put the BPs to
0x000A, 0x000B, 0x000C, 0x000D, 0x000E with the key F9, and if it
is inserted more than 10 BP, the BP A, B, C, D, E cannot be removed
with the key F9.

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.
* Added Crosshair Options menu
- ability to individually enable/disable crosshairs
- ability for them to automatically disappear after a set amount of time
- ability to select crosshair graphic
- all settings are saved in the cfg file
* Removed F1 toggle for crosshairs
* Added new command option -crsshairpath
- store all selectable graphics here
- see config.txt for further info
OSD NOTE: render_load_png() has been changed to no longer force usage of the artwork directory.
Do a search for "render_load_png(" and replace with "render_load_png(OPTION_ARTPATH, " if needed.
----------------------------
F1 is now free to use for something new. I was thinking it would be perfect for a context sensitive help file. Each menu item could have a help tag, that it would look up and display info from an HTML file.
* Fix build of ldplayer on OS X. Since the CUSTOM sound module no longer exists, I
arbitrarily changed it to WAVE, as ar gets upset if it has no input files. I also
removed the -all_load flag for ldplayer from the main makefile as it upsets the linker
on OS X.
* Fix build for PPC64 Linux. (This slightly messes up static branch prediction hints
on OS X and AIX, but OS X for PPC64 is dead, and no- one builds MAME for AIX, and
it will still build, anyway.)
* Paramaterise the arguments to check for NULL in the ATTR_NONNULL macro rather than
just checking the first argument. This requires compiler support for C99 variadic
macros (MSVC2005 and GCC4 have this AFAIK).
Vas
* corrupt files in archives now generate an error
* archive files ending in "/" will not be tested for crc - skip path entries
* add new flag FILE_OPEN_NO_PRELOAD to skip decompressing on open
This is used in audit.c, which only tests whether files exist
* added error checking to all calls to load_file_zipped
compilation:
- new option CPP_COMPILE to trigger this (off by default)
- split CFLAGS into common, C-only, and C++-only flags
- when enabled, CPP_COMPILE causes 'pp' to be appended to
the target name
NOTE THAT THE SYSTEM CANNOT ACTUALLY BE COMPILED THIS WAY
YET. IT IS JUST AN EXPERIMENT.
Modified lib.mak to always build zlib/expat as C regardless
of CPP_COMPILE.
Modified windows.mak to fix warnings with MAXOPT=1, and to
leverage the new CFLAGs definitions.
Modified vconv.c to do appropriate conversions for new C++
options.
Updated sources so that libutil, libocore (Windows), and
libosd (Windows) can be cleanly compiled as C or C++. This
was mostly adding some casts against void *.
Fixed a few more general obvious problems at random
locations in the source:
- device->class is now device->devclass
- TYPES_COMPATIBLE uses typeid() when compiled for C++
- some functions with reserved names ('xor' in particular)
were renamed
- nested enums and structs were pulled out into separate
definitions (under C++ these would need to be scoped to
be referenced)
- TOKEN_VALUE cannot use .field=x initialization in C++ :(
which control the font and size used in the debugger text Windows. These
default to "Lucida Console" and 9pt, which is the same face as previously
hard-coded but 1pt larger. Personally, I prefer "Consolas" 9pt, which is
one of the new "C" fonts included with Windows Vista and later (also
available for free download on older systems). Note that only fixed-width
fonts really work here, for obvious reasons.
(It was doing a double-shift for CPUs with a address shift)
(The bpset command seems to occasionally behave oddly for cpus with address shifts as well. Didn't figure that problem out in the few minutes i looked at it.)
necessary to remove 12 of the final 14 references to the global
Machine. The remaining 2 are in fatalerror() and logerror(), which
are both local to mame.c, so Machine is now fully static.

Subject: [patch] Make Machine static followup
Hi mamedev,
This incremental patch to my last patch undoes the change that caches
the ppu2c0x videorom. I changed the code back to how it behaved
originally, using an existing machine on the chip struct to eliminate
the one troublesome Machine reference.

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.

debugger. In order to get the OSD to update, a new function
debug_view_flush_updates() must be called. Currently this is automatically
called before osd_wait_for_debugger(), and during the periodic updates while
executing. The OSD code may occasionally need to call it under other
circumstances (for example, the Windows code calls it explicitly while
tracking scrollbar thumbs to get live scrolling).

Subject: [patch] Deprecat.h cleanup
Hi mamedev,
This patch changes some global Machine references to use machine,
device->machine, ... instead, and removes any unneeded #include
"deprecat.h" lines as well (about 10% of them in fact). It was
generated using the attached script, and then reverting some cases
where it was overzealous.
~aa
* select correct memory region by default when created
(should be first address space of visible CPU)
* when created, default bytes/chunk is correct
* when changing width, cursor no longer moves around
* memory regions display more than all 0xff now
Also fixed:
* qword big-endian memory reads no longer call little-endian handlers
* memory regions are tracked in creation order (show up in order
in the menu now)
* ROMREGION_DISPOSE memory regions are not disposed if the debugger
is enabled
02683: Pressing F5 while running debugger causes access violation
02669: pandoras: music tempo is too fast
02691: Some drivers with z80/ay8910 Audio: Audio tempo has changed
Also fixed debugger memory leak.
Added a number of new cputag_* macros to cpuexec.h.
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.
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.
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.
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.
- removed unnecessary deprecat.h includes
- replaces Machine with existing running_machine* instances
- re-adds a peroid I accidentally removed when changed a message to
use defines
- adds a running_machine* to win_window_info and debugwin_info to get
rid of most Machine occurances and clean up the running_machine*
parameters I added in the past
