global functions which are now superceded by the operators and
methods on the class. [Aaron Giles]
Required mappings are:
attotime_make(a,b) => attotime(a,b)
attotime_to_double(t) => t.as_double()
double_to_attotime(d) => attotime::from_double(d)
attotime_to_attoseconds(t) => t.as_attoseconds()
attotime_to_ticks(t,f) => t.as_ticks(f)
ticks_to_attotime(t,f) => attotime::from_ticks(t,f)
attotime_add(a,b) => a + b
attotime_add_attoseconds(a,b) => a + attotime(0, b)
attotime_sub(a,b) => a - b
attotime_sub_attoseconds(a,b) => a - attotime(0, b)
attotime_compare(a,b) == 0 => a == b
attotime_compare(a,b) != 0 => a != b
attotime_compare(a,b) < 0 => a < b
attotime_compare(a,b) <= 0 => a <= b
attotime_compare(a,b) > 0 => a > b
attotime_compare(a,b) >= 0 => a >= b
attotime_mul(a,f) => a * f
attotime_div(a,f) => a / f
attotime_min(a,b) => min(a,b)
attotime_max(a,b) => max(a,b)
attotime_is_never(t) => t.is_never()
attotime_string(t,p) => t.as_string(p)
In addition, some existing #defines still exist but will go away:
attotime_zero => attotime::zero
attotime_never => attotime::never
ATTOTIME_IN_SEC(s) => attotime::from_seconds(s)
ATTOTIME_IN_MSEC(m) => attotime::from_msec(m)
ATTOTIME_IN_USEC(u) => attotime::from_usec(u)
ATTOTIME_IN_NSEC(n) => attotime::from_nsec(n)
ATTOTIME_IN_HZ(h) => attotime::from_hz(h)
- Created new central header "emu.h"; this should be included
by pretty much any driver or device as the first include. This
file in turn includes pretty much everything a driver or device
will need, minus any other devices it references. Note that
emu.h should *never* be included by another header file.
- Updated all files in the core (src/emu) to use emu.h.
- Removed a ton of redundant and poorly-tracked header includes
from within other header files.
- Temporarily changed driver.h to map to emu.h until we update
files outside of the core.
Added class wrapper around tagmap so it can be directly included
and accessed within objects that need it. Updated all users to
embed tagmap objects and changed them to call through the class.
Added nicer functions for finding devices, ports, and regions in
a machine:
machine->device("tag") -- return the named device, or NULL
machine->port("tag") -- return the named port, or NULL
machine->region("tag"[, &length[, &flags]]) -- return the
named region and optionally its length and flags
Made the device tag an astring. This required touching a lot of
code that printed the device to explicitly fetch the C-string
from it. (Thank you gcc for flagging that issue!)
osd_free(). They take the same parameters as malloc() and free().
Renamed mamecore.h -> emucore.h.
New C++-aware memory manager, implemented in emualloc.*. This is a
simple manager that allows you to add any type of object to a
resource pool. Most commonly, allocated objects are added, and so
a set of allocation macros is provided to allow you to manage
objects in a particular pool:
pool_alloc(p, t) = allocate object of type 't' and add to pool 'p'
pool_alloc_clear(p, t) = same as above, but clear the memory first
pool_alloc_array(p, t, c) = allocate an array of 'c' objects of type
't' and add to pool 'p'
pool_alloc_array_clear(p, t, c) = same, but with clearing
pool_free(p, v) = free object 'v' and remove it from the pool
Note that pool_alloc[_clear] is roughly equivalent to "new t" and
pool_alloc_array[_clear] is roughly equivalent to "new t[c]". Also
note that pool_free works for single objects and arrays.
There is a single global_resource_pool defined which should be used
for any global allocations. It has equivalent macros to the pool_*
macros above that automatically target the global pool.
In addition, the memory module defines global new/delete overrides
that access file and line number parameters so that allocations can
be tracked. Currently this tracking is only done if MAME_DEBUG is
enabled. In debug builds, any unfreed memory will be printed at
the end of the session.
emualloc.h also has #defines to disable malloc/free/realloc/calloc.
Since emualloc.h is included by emucore.h, this means pretty much
all code within the emulator is forced to use the new allocators.
Although straight new/delete do work, their use is discouraged, as
any allocations made with them will not be tracked.
Changed the familar auto_alloc_* macros to map to the resource pool
model described above. The running_machine is now a class and contains
a resource pool which is automatically destructed upon deletion. If
you are a driver writer, all your allocations should be done with
auto_alloc_*.
Changed all drivers and files in the core using malloc/realloc or the
old alloc_*_or_die macros to use (preferably) the auto_alloc_* macros
instead, or the global_alloc_* macros if necessary.
Added simple C++ wrappers for astring and bitmap_t, as these need
proper constructors/destructors to be used for auto_alloc_astring and
auto_alloc_bitmap.
Removed references to the winalloc prefix file. Most of its
functionality has moved into the core, save for the guard page
allocations, which are now implemented in osd_alloc and osd_free.
convert between attotimes and a clock tick at an integral frequency.
Changed the 6532 RIOT device into a proper device. Rewrote the
logic to be simpler and leverage the new attotime functions. Changed
the I/O port setters to specify a mask, and changed the I/O port
callbacks to pass in the previous value. Updated tourtabl and
gameplan drivers to use the new device interface.
Converted audio/starwars.c, audio/exidy.c, and audio/gottlieb.c to
use the new RIOT implementation instead of rolling their own.
Began gottlieb.c cleanup. Converted palette calculations to resistor
weights. Corrected video timing. Reduced the number of separate
machine drivers. Fixed incorrect spriteram sizes. Populated full
memory maps for the main CPU and the rev 1 sound board. More to
come.
constructors to tokenized lists. For the most part
this is a non-invasive change, except for those drivers
using MDRV_WATCHDOG_TIME_INIT. In order to allow for
tokenization of attotimes, a set of new macros is
provided called UINT64_ATTOTIME_IN_x() which follows the
same pattern as ATTOTIME_IN_x() but packs the attotime
down into a single 64-bit value for easier tokenization.
Separated MDRV_DEVICE_CONFIG_DATA into 32-bit and 64-bit
versions. Added floating-point versions with configurable
resolutions.
Fixed several errors in the machine drivers which were
caught by the additional checks now done in the machine
config detokenization code.
Converted speakers into devices. Machine->config no
longer houses an array of speakers; instead they are
iterated through using the new macros (defined in sound.h)
speaker_output_first() and speaker_output_next(). Updated
all relevant code to do this.
Improved game info display with multiple screens. Fixed
bug which caused all screens to display equally.
Added typedefs for all the machine config callback
functions at the top of driver.h.
- removed years from copyright notices
- removed redundant (c) from copyright notices
- updated "the MAME Team" to be "Nicola Salmoria and the MAME Team"
