For reasons unknown to me compile optimizations do not behave for
template code. If the implementation is in separate compile units, the
code compiles and performs.
This needs more attention since for certain compilers there is a
considerable performance degregation. It looks like this is only
triggered if too many variants are declared in one cpp file and the
compiler stops inlining.
Thanks to Aaron Giles who made me think about a different approach.
This is a rewrite from scratch for rom devices. It uses a generic
template to implement rom devices which is used together with a
description struct to define a rom device. This leads to highly
efficient code since all information is available at compile time.
This is also a step forward to support tristate outputs. All rom devices
covered by this approach have tristate or open collector outputs and
thus all code changes to support tristate outputs can now be made
consistently in one file.
Code cleanup to better separate the following stages:
- parsing
- setup
- run
In addition preliminary native tristate support was added. Not yet
production ready, please don't use it.
The two sources act as voltage sources, though noise may also be
injected as conductivy or current noise.
SYS_NOISE_MT_U: Mersenne Twister uniform noise
SYS_NOISE_MT_N: Mersenne Twister normal noise
nld_sys_noise is templated:
using NETLIB_NAME(sys_noise_mt_u) =
NETLIB_NAME(sys_noise)<plib::mt19937_64,
plib::uniform_distribution_t>;
Thus the approach is scalable. The implementation is state save aware,
and thus reproducible results are guaranteed.
An example use case is provided as well, see examples/noise.cpp.
* new WORKING machines
Millennium M505 Arcade Neo Portable Spielkonsole (Family Sport 100-in-1) [TeamEurope]
* new NOT WORKING software list entries
tvgogo.xml : Baseball (US) [Sean Riddle, David Haywood]
tvgogo.xml : What-A-Mole (US) [Sean Riddle, David Haywood]
* added internal NAND dump to didj [Sean Riddle, Clawgrip]
The device can be found in nlm_other.cpp.
Removed nld_ne566.*
Added SYS_SW, SYS_SW2 and SYS_COMP. These are single switch,
alternating switch and a analog comparator with digital outputs.
Renamed RES_SWITCH to SYS_SW.
Added example ne566.cpp in netlist/examples.

MDT 60 Video Display Terminal [Bitsavers, AJR]
z29: Add skeleton for undumped keyboard; try (and fail) to make this work with the MDT 60 keyboard instead
z22: Separate driver (nw)
Changes:
- added known dump checksums of 1101 BIOS
- high-level emulation of GPIB disk devices
- partial implementation of DMA (currently ignores ACCRQ so devices must have zero latency in order for it to work)
- serial is now properly memory-mapped
- modem stub in order to make system properly ignore modem device
- it now boots without any patches and debug scripts
- merged #6597 (needed in order to make disk devices work)
Still not implemented:
- RTC/MACHINE_ID
- modem
- has problems with multiple disk devices working simultaneously (possibly BIOS bug because this BIOS had some problems with that on real device)
* Initial refactor of AVI/MNG movie recording, consolidation of copy and paste
code, hiding of AVI/MNG behind interfaces
* Extracted recording specific code out of src/emu/video.cpp and put into
src/emu/recording.cpp
* Took the opportunity to move slightly more logic out of video.cpp into
recording.cpp
* Bug fix
* Consolidated frame counting logic
Added a define NL_USE_ACADEMIC_SOLVERS and disabled it in the build.
This will not compile in solvers which are either illustrative or only
perform for large sparse matrices like GMRES.
Moved netlist between dasm and utils,expat,... link statements
This fixes the resolution of symbols in netlist code which may be used
in machine/netlist.cpp.
Change tested on ubuntu, windows and macosx.
This commit introduces precompiled static solver code. Due to
additional optimizations the compiler can use because the detail
calculation steps for the solution are known e.g. the kidniki netlist
sees a 100% speed increase.
In all environments (windows/*nix/osx) the source for the static
solver code can be created using
bash src/lib/netlist/nl_create_mame_solvers.sh
This will create src/lib/netlist/generated/static_solvers.cpp which is
compiled into the mame binary.
The script is just a temporary workaround. The intention is that nltool
whill be able to create this file with one call.
There are other improvements in this commit speeding up the processing
of timestep and dynamic calculations.
- PAC2 is now a separate bus with slot devices
- Kanji ROM and RAM PAC2 expansions are no longer built into pasopia7, but may be configured as slot options
- RAM PAC2 expansion made nonvolatile and provided in multiple sizes
- Two PAC2 slots added to pasopia
* Split S-SMP and S-DSP implement in snes_snd.cpp
both convert memory handler into device_memory_interface, Internalize ROM region of S-SMP
s_smp.cpp : Use callback for S-DSP interface, Split internal and external memory space
snes.cpp : Convert WRAM into shared_ptr
* s_dsp.cpp : Reduce #define macros
- com8116: Delete SY2661-1/-2 tables (these are just second sources of SCN2661A/B)
- mc2661: Remove obsolete device
- rs232: Remove 7200 baud setting formerly required by one driver to work around incorrect table
visualiser device and WDL FFT libarary).
I changed the VGM visualiser to use single-precision float which is the
default for WDL FFT. GCC's loop vectoriser can make better use of SSE
with single-precision maths, and the extra precision shouldn't be needed
for the visualisation. If this is a problem, let me know and I'll
revert this and flip the WDL FFT library over the other way.
(nw) The pcap.h header itself has the problematic original BSD license,
including the obnoxious advertising clause. Using tap/tun networking on
Windows provides a much better experience, so the extra setup is worth
it. This patch also allows you to enable pcap on platforms where it's
disabled by default with USE_PCAP=1 if you really want to use it.
* Removed empty nl_examples from dist.mak
* Added copyright acknowledgements and full text of licenses to binary distribution
* Fixed up the list of third-party libraries
* Moved WDL fft.c to 3rdparty
* hp80: added HP82939 serial I/O module.
Fixed a small bug in INS8250 that prevented module self-test to pass.
Improved the interrupt handling of hp80 systems.
* hp80: changed scheduling to use "set_perfect_quantum"
This tool was previously used to generate HTML-formatted source for
the website from releases. It hasn't been used in years, since we
rely on the repository browsing features of GitHub/GitLab/SourceForge.
It also hasn't been updated to handle C++14, Lua, and other changes to
the source. If we do want to publish source code on our own web site
in the future, we'd be better off using an off-the-shelf library to
handle parsing the source.

ioport.cpp:
* better than 50% reduction in compile time, and better locality for static data
* better encapsulation, const correctness and noexcept usage
* When a switch-type input is selected, show feedback when it's pressed
* If an invalid code is entered (e.g. only negatives) abandon the change rather than cycling default/none
* If an invalid code is entered display a message until the user takes some other action
input.cpp updates:
* constexpr crusade on input_code and input_seq and some very slight optimisation to input_seq
* seq_poll* is a frontend function and had no business being in the core, so it's a utility class now
* seq_poll* now exposes a bit more detail, enabling improved interaction on the UI inputs menu
* global state is reduced a little, but the poll_* functions are still members of the input manager with global state
(nw) The Lua engine has been updated in a way that maintains source compatibility with existing Lua
scripts. This is less than ideal, but it minimises impact. Ideally someone (possibly me) will be
able to expose the input sequence poller helper properly. I tested the changes with the cheat and
autofire plugins and I was able to assign sequences. However I found two issues: it's seems
impossible to assign a more complex sequence than a single key/button in the autofire plugin (i.e.
no AND or NOT conditions, I confirmed this is pre-existing, not a regression), and in both the cheat
and autofire plugins I found it a bit unwieldy trying to enter a complex sequence without live
feedback of the sequence as it's built (this was also applicable to MAME's own input mapping menu
until I added the live display yesterday).
