instructions whose execution time is normally indefinite. When this happens, a special message may be printed to the debug console stating the location of the last actual instruction executed before the wait (if there was one).
Note that since the callback ignores the current value of the program counter, this special type of debugger break cannot be entered through breakpoints or instruction stepping commands. The callback also leaves no effect on PC history tracking or trace logs.

Read callbacks now need a default return value supplied at construction.
Replaced isnull() with isunset() which tells you if the callback wasn't
configured rather than whether it isn't safe to call.
Enabled validation of device callbacks (it seems it was disabled at some
point, probably accidentally).
Device callbacks and object finders now implement the same interface for
resolution.

This simplifies looking up the target device during configuration. It
is useful when configuring child devices in things like CPUs with
integrated peripherals.
emu/device.h: Allow templated subdevice() and siblingdevice() to work
with classes that don't derive from device_t (e.g. classes that derive
from device_interface).
util/delegate.h: Added more noexcept. Won't make much difference as
most of the affected member functions are inline anyway.

members. (#9788)
Primarily, this removes device_t::device_timer, device_t::timer_set,
device_t::synchronize, device_t::timer_expired, and device_timer_id.
Use of device_timer often resulted in unnecessary trampolining in
addition to switch/case overhead on a driver/device level, and
additional logic to manage delegated vs. ID-based timers on a core
level. In the worst cases, devices were performing a switch/case with
only one valid case.
device_scheduler::timer_set is marked deprecated as the only remaining
direct uses are via the Lua engine and a few drivers that need
refactoring anyway. The remaining uses occur via
device_scheduler::synchronize.
As a middle ground between the extremely short timer_alloc() and the
extremely long
machine().scheduler().timer_alloc(timer_expired_delegate(FUNC(widget_device::contoso_tick), this)),
a helper function in device_t has been added which can be invoked with
the following syntax:
timer_alloc(FUNC(widget_device::contoso_tick), this)

- Add 'gbt' and 'gbf' debugger commands to step until a true or false conditional branch has been detected.
- Update over 100 of the disassemblers in MAME to output a new STEP_COND flag for all conditional branches. Besides being used for execution of the new 'gbt' and 'gbf' commands, this flag also now helps the debugger 'out' command to properly handle conditional return instructions.
- Remove STEP_OVER from many instructions that aren't actually subroutine calls (e.g. DJNZ on Z80). A 'gni' debugger command (go next instruction) has been added to accommodate some of the misuse.
- Add instruction flag support to several more disassemblers that lacked them entirely (e.g. st62xx)
- Don't pass over delay slots for debugging in ASAP core

- Remove the hotspot read tracker. This was never robustly implemented, but changes to the memory system made it much less useful, and the "speedup opportunities" which it aimed to determine are not very important from a current emulation standpoint.
- Remove the CURSP/GENSP state symbol and the generic sp() getter. Stacking semantics vary too much between CPU architectures for this to be of much use. (A "SP" symbol has been added to a few CPU cores whose stack pointers were otherwise not being registered.)
- Remove the cached pointer to device_state_interface and the state() fast accessor from device_t. Most users of device_state_interface either already had a pointer to the specific CPU device type or needed to check first for the presence of the interface.
- Change the PC memory write tracker to use pcbase(), which works even when the instruction callback is masked out, instead of peeking at the PC history index.
- Remove some obsolete watchpoint-related definitions from machine.h.

not pointers anymore [O. Galibert]
The last(?) two changes are:
- Add a template parameter to everything (theoretically the address
space width, in practice a level derived from it to keep as much
compatibility between widths as possible) so that the shift size
becomes a constant.
- Change the syntax of declaring and initializing the caches and
specifics so that they're embedded in the owner device. Solves
lifetime issues and also removes one indirection (looking up the base
dispatch pointer through the cache/specific pointer).

fundamental change to show device delegates are configured.
Device delegates are now aware of the current device during
configuration and will resolve string tags relative to it. This means
that device delegates need a device to be supplied on construction so
they can find the machine configuration object. There's a
one-dimensional array helper to make it easier to construct arrays of
device delegates with the same owner. (I didn't make an n-dimensional
one because I didn't hit a use case, but it would be a simple addition.)
There's no more bind_relative_to member - just call resolve() like you
would for a devcb. There's also no need to cast nullptr when creating a
late bind device delegate. The flip side is that for an overloaded or
non-capturing lambda you'll need to cast to the desired type.
There is one less conditional branch in the hot path for calls for
delegates bound to a function pointer of member function pointer. This
comes at the cost of one additional unconditional branch in the hot
path for calls to delegates bound to functoids (lambdas, functions that
don't take an object reference, other callable objects). This applies
to all delegates, not just device delegates.
Address spaces will now print an error message if a late bind error is
encountered while installing a handler. This will give the range and
address range, hopefully making it easier to guess which memory map is
faulty.
For the simple case of allowing a device_delegate member to be
configured, use a member like this:
template <typename... T> void set_foo(T &&...args) { m_foo_cb.set(std::forward<T>(args)...); }
For a case where different delegates need to be used depending on the
function signature, see src/emu/screen.h (the screen update function
setters).
Device delegates now take a target specification and function pointer.
The target may be:
* Target omitted, implying the current device being configured. This
can only be used during configuration. It will work as long as the
current device is not removed/replaced.
* A tag string relative to the current device being configured. This
can only be used during configuration. It will not be callable until
.resolve() is called. It will work as long as the current device is
not removed/replaced.
* A device finder (required_device/optional_device). The delegate will
late bind to the current target of the device finder. It will not
be callable until .resolve() is called. It will work properly if the
target device is replaced, as long as the device finder's base object
isn't removed/replaced.
* A reference to an object. It will be callable immediately. It will
work as long as the target object is not removed/replaced.
The target types and restrictions are pretty similar to what you already
have on object finders and devcb, so it shouldn't cause any surprises.
Note that dereferencing a device finder will changes the effect. To
illustrate this:
...
required_device<some_device> m_dev;
...
m_dev(*this, "dev")
...
// will late bind to "dev" relative to *this
// will work if "dev" hasn't been created yet or is replaced later
// won't work if *this is removed/replaced
// won't be callable until resolve() is called
cb1.set(m_dev, FUNC(some_device::w));
...
// will bind to current target of m_dev
// will not work if m_dev is not resolved
// will not work if "dev" is replaced later
// will be callable immediately
cb2.set(*m_dev, FUNC(some_device::w));
...
The order of the target and name has been reversed for functoids
(lambdas and other callable objects). This allows the NAME macro to
be used on lambdas and functoids. For example:
foo.set_something(NAME([this] (u8 data) { m_something = data; }));
I realise the diagnostic messages get ugly if you use NAME on a large
lambda. You can still give a literal name, you just have to place it
after the lambda rather than before. This is uglier, but it's
intentional. I'm trying to drive developers away from a certain style.
While it's nice that you can put half the driver code in the memory map,
it detracts from readability. It's hard to visualise the memory range
mappings if the memory map functions are punctuated by large lambdas.
There's also slightly higher overhead for calling a delegate bound to a
functoid.
If the code is prettier for trivial lambdas but uglier for non-trivial
lambdas in address maps, it will hopefully steer people away from
putting non-trivial lambdas in memory maps.
There were some devices that were converted from using plain delegates
without adding bind_relative_to calls. I fixed some of them (e.g.
LaserDisc) but I probably missed some. These will likely crash on
unresolved delegate calls.
There are some devices that reset delegates at configuration complete or
start time, preventing them from being set up during configuration (e.g.
src/devices/video/ppu2c0x.cpp and src/devices/machine/68307.cpp). This
goes against the design principles of how device delegates should be
used, but I didn't change them because I don't trust myself to find all
the places they're used.
I've definitely broken some stuff with this (I know about asterix), so
report issues and bear with me until I get it all fixed.
