C++11 range-based for loops can now iterate over simple_list, tagged_list, core_options, device_t::subdevice_list, device_t::interface_list, render_primitive_list and all subclasses of the above, and much code has been refactored to use them. Most core classes that have these lists as members now have methods that return the lists themselves, replacing most of the methods that returned the object at an owned list's head. (A few have been retained due to their use in drivers or OSD.)
device_t now manages subdevice and interface lists through subclasses, but has given up the work of adding and removing subdevices to machine_config.
memory_manager has its tagged lists exposed, though the old rooted tag lookup methods have been removed (they were privatized already).

Fixed an annoying inconsistency between memory_share and memory_region:
the width() method of the former returned the width in bits (8, 16, 32 or 64)
while the width() method of the latter returned the width in bytes
(1, 2, 4 or 8). Now both classes have a bitwidth() method and a bytewidth()
method. Updated all callers to use whichever one was more appropriate.
Removed the implicit-cast-to-any-integer-pointer ability of memory_regions,
which was rather unsafe (if you weren't careful with your * operators and
casts it was easy to accidentally get a pointer to the memory_region object
itself instead of to the data, with no warning from the compiler... or at
least I kept doing it) Updated all devices and drivers that were accessing
regions that way to use a region_ptr_finder when possible, and otherwise to
call base() explicitly.

[Aaron Giles]
* these classes now no longer take a resource_pool; everything is
managed globally -- this means that objects added to lists must be
allocated with global_alloc
* added new auto_pointer<> template which wraps a pointer and auto-frees
it upon destruction; it also defaults to NULL so it doesn't need to
be explicitly initialized
* moved tagged_list template to tagmap.h
Redo of the low-level memory tracking system: [Aaron Giles]
* moved low-level tracking out of emu\emualloc into lib\util\corealloc
so it can be shared among all components and used by core libraries
* global_alloc and friends no longer use a resource pool to track
allocations; turns out this was a wholly redundant system that wasted
a lot of memory
* removed global_resource_pool entirely
* added global_free_array to delete arrays allocated with
global_alloc_array
* added tracking of object versus array allocation; we will now error
if you use global_free on an array, or global_free_array on an object
Added new utility helper const_string_pool which can be used to
efficiently accumulate strings that are not intended to be modified.
Used by updated makelist and software list code. [Aaron Giles]
Updated png2bdc and makelist tools to not leak memory and use more modern
techniques (no more MAX_DRIVERS in makelist, for example). [Aaron Giles]
Deprecated auto_strdup and removed all uses by way of caller-managed
astrings and the software list rewrite. [Aaron Giles]
Rewrote software list management: [Aaron Giles]
* removed the notion of a software_list that is separate from a
software_list_device; they are one and the same now
* moved several functions into device_image_interface since they really
didn't belong in the core software list class
* lots of simplification as a result of the above changes
Additional notes (no whatsnew):
Moved definition of FPTR to osdcomm.h.
Some changes happened in the OSD code to fix issues, especially regarding
freeing arrays. SDL folks may need to fix up some of these.
The following devices still are using tokens and should be modernized
(I found them because they kept their token as void * and tried to
delete it, which you can't):

Tilemap system: numerous changes:
* Moved remaining legacy macros and typedefs to tilelgcy.h. This revealed
a few drivers mixing and matching modern & legcy, which have now been
fixed.
* Changed get info callback signature to no longer pass the user_data
pointer, but instead pass a reference to the tilemap object itself.
Updated those few drivers using user_data to pull it out of the
tilemap object with the new user_data() getter method.
* Changed get info and mapping callbacks to be device_delegates so that
they can be described at config time.
* Added tilemap_memory object that is used internally for reading/
writing to memory that backs a tilemap. This object is used to track
a memory pointer that backs tilemap memory, and also is designed to
transparently handle all bus width and endianness associated with
reading and writing data in a tilemap.
* Incorporated two tilemap_memory objects (basemem and extmem) into the
tilemap object and added accessors to them, as well as read/write
handlers for reading/writing to entries stored in the memory. This
means that tilemap get info callbacks can now easily read data out of
the tilemap in a generic way.
* Rejiggered the initialization sequence for tilemap objects so that
the tilemap_manager is not required to be present at instantiation.
* Created a new tilemap_device, which can be used to declare a tilemap
in the machine config, and which also is a tilemap object itself.
The tilemap device will look for shared memory regions called
"<tag>" and "<tag>_ext" and automatically plug them into the tilemap.
The device also provides write handlers that can be used to write
to the tilemap memory and mark tiles dirty, saving the need for each
driver to write their own.
Device system: moved required/optional device finders to a new header
devfind.h.
Atari drivers: removed all playfield and alpha memory and tilemap
variables, apart from those needed by atarivc-using games (this will
become a device in a future update). Updated all Atari 16-bit drivers to
use the new tilemap_device instead, which provides all the needed
functionality in a more generic way.

Situation:
- you have a device (pc-fdc) with a memory map on it
- you map it dynamically into a cpu (maincpu) address space with install_device (isa-fdc does that)
- the device pc-fdc has a subdevice (upd765)
- the subdevice upd765 has its own memory map
- the pc-fdc memory map includes the upd765 memory map through AM_DEVICE("upd765", ...)
Before the fix, the code would search for upd765 as a subdevice of
maincpu and not of pc-fdc.

non-templatized helper class so that the code can live
co-located, rather than invading device.h.
Changed the read/write delegates to derive from
device_delegate. Updated the address map macros to create
these properly.
Removed remnants of the old AM_BASE/SIZE macros from the
memory system.
|
| |
|
|
|
|

All legacy device callbacks are now promoted to delegates
and handed off to the modern read/write handler managers.
Fixed ibm5150 and surely many other broken systems. (nw)

to 8-bit handlers to match the others. To ease
pain, added DECLARE_READ/WRITE_HANDLER macros that
set up a default parameter. Also updated devcb so
that the handlers can be called with or without the
mem_mask. [Aaron Giles]

read/write handlers to take an address_space & instead
of an address_space *. Also update pretty much all other
functions to take a reference where appropriate.

READ/WRITE_DEVICE*_HANDLERs are now passed an
address_space &, and the 8-bit variants get a mem_mask
as well. This means they are now directly compatible
with the member function delegates. Added a generic
address space to the driver_device that can be used
when no specific address space is available. Also
added DECLARE_READ/WRITE_DEVICE*_HANDLER macros to
declare device callbacks with default mem_mask
parameters. [Aaron Giles]

Just call install_device on the space with as parameters:
- start and end of the mapping zone
- device (not pointer to the device)
- map method
and optionally, if the device data width is not the same than the
space data width:
- device data width (for consistency checking)
- unit mask
For instance, the static mapping:
AM_RANGE(0x02114100, 0x02114107) AM_DEVICE8("fdc", n82077aa_device, amap, 0xffffffff)
can be converted to a dynamic mapping (where fdc is a pointer to the device):
machine().device("maincpu")->memory().space(AS_PROGRAM)->
install_device(0x02114100, 0x02114107, *fdc, &n82077aa_device::amap, 8, 0xffffffff);

memory_region management into the memory manager instead
of directly in the machine. Hid the global region method;
now all regions must be looked up relative to a device.
If you're a member function, you can just use memregion("tag")
directly. If you're a global function or a device referencing
global regions, use machine().root_device().memregion("tag")
to look up regions relative to the root.
S&R to convert all references:
machine([()]*)\.region
machine\1\.root_device\(\).subregion
Then remove redundant machine().root_device() within src/mame:
([ \t])machine\(\)\.root_device\(\)\.
\1
And use state->memregion() if we have a state variable present:
(state *= *[^;]+driver_data[^}]+)([^ \t]*)machine[()]*\.root_device\(\)\.
\1state->
Finally some cleanup:
screen.state->
state->
device->state->
state->
space->state->
state->
And a few hand-tweaks.
