* Revert initialisation of device members in headers. Vas Crabb2022-04-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This is problematic in several ways: * Initialising things at construction that aren't needed until after start slows down -romident, -validate, -listxml, etc. Slot cards can be a particular drain on -listxml and -validate as they're instantiated for every compatible slot. It's more pronounced for array members, too. * Splitting member initialisation between declaration in headers and constructors in source files means you have to look at two places to check for the initial value, and you always need to check the constructor even if an initialiser is present in the header because the constructor initaliser list takes precedence. (This isn't as much of an issue for driver classes because the constructor is most often inlined at declaration, so it isn't far from the member declarations.) * Initialisers in headers for frequently-used devices increases the frequency of recompiling dependent devices/drivers as they're exposed to any changes in initialisers. * Initialisers in frequently-used headers increase build times because there's more for the compiler to parse/cache. (This affects makedep.py as well for single-driver builds, but that's a single pass.) It's not a lot individually, but it adds up given the size of MAME, which keeps increasing. We've already had one contributor banned from GitHub actions for resource usage, we don't want to waste compiler time unnecessarily.

* Fairly significant overhaul of Lua engine and some cleanup. Vas Crabb2020-11-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The things that were previously called device iterators are not iterators in the C++ sense of the word. This is confusing for newcomers. These have been renamed to be device enumerators. Several Lua methods and properties that previously returned tables now return lightweight wrappers for the underlying objects. This means creating them is a lot faster, but you can't modify them, and the performance characteristics of different operations varies. The render manager's target list uses 1-based indexing to be more like idiomatic Lua. It's now possible to create a device enumerator on any device, and then get subdevices (or sibling devices) using a relative tag. Much more render/layout functionality has been exposed to Lua. Layout scripts now have access to the layout file and can directly set the state of an item with no bindings, or register callbacks to obtain state. Some things that were previously methods are now read-only properties. Layout files are no longer required to supply a "name". This was problematic because the same layout file could be loaded for multiple instances of the same device, and each instance of the layout file should use the correct inputs (and in the future outputs) for the device instance it's associated with. This should also fix video output with MSVC builds by avoiding delegates that return things that don't fit in a register.
* Spring cleaning: Vas Crabb2019-11-012-41/+30
| | | | | | | | | | | | * Changed emu_fatalerror to use util::string_format semantics * Fixed some incorrectly marked up stuff in build scripts * Make internal layout compression type a scoped enum (only zlib is supported still, but at least the values aren't magic numbers now) * Fixed memory leaks in Xbox USB * There can only be one "perfect quantum" device - enforce that only the root machine can set it, as allowing subdevices to will cause weird issues with slot cards overiding it * Allow multiple devices to set maximum quantum and use the most restrictive one (it's maximum quantum, it would be minimum interleave) * Got rid of device_slot_card_interface as it wasn't providing value * Added a helper template to reduce certain kinds of boilerplate in slots/buses * Cleaned up some particularly bad slot code (plenty more of that to do), and made some slots more idiomatic
* (nw) Clean up the mess on master Vas Crabb2019-03-261-12/+11
| | | | | | | | | | | | | This effectively reverts b380514764cf857469bae61c11143a19f79a74c5 and c24473ddff715ecec2e258a6eb38960cf8c8e98e, restoring the state at 598cd5227223c3b04ca31f0dbc1981256d9ea3ff. Before pushing, please check that what you're about to push is sane. Check your local commit log and ensure there isn't anything out-of-place before pushing to mainline. When things like this happen, it wastes everyone's time. I really don't need this in a week when real work™ is busting my balls and I'm behind where I want to be with preparing for MAME release.

* Make MCFG_DEVICE_ADD and callable device types more flexible: Vas Crabb2018-05-042-17/+18
| | | | | | | | | | | | | | | | | | | | | * Allows defaulted clocks (see subtle example with vboy) * Allows additional constructors (see RS232 port in tranz330) * Allows use of device finder in place of tag in MCFG_DEVICE_ADD * Requires out-of-line destructor for devices using incomplete types * Requires XTAL or explicit u32 for clocks for devices with private types Devices must still define the standard constructor. When writing additional constructors, be aware that the constructor runs before device_add_mconfig in the context of the existing device, not the new device. See osborne1, zorba, tranz330, and vboy for examples of this in use. Compilation is a bit slower, but this is temporary while refactoring is in progress. Eliminated the need for MCFG_SOUND_ROUTE_EX. Removed macros from slot option configuration - they just obfuscated code and slowed it down with needless dynamic casts, but didn't actually simplify it.
