- solver: align matrix population along the various solvers
- solver: delete dead code
- renamed nl_double to nl_fptype and use nl_fptype where previously
double has been used.
- renamed param_double_t to param_fp_t
- Removed code no longer used
- Add noexcept where appropriate
- split pparser.[c|h] into ppreprocessor and ptokenizer
- smaller optimizations, e.g. use of std::size_t
- fix lint warnings
- Added support for line markers to the preprocessor and parser.
- Added support for include processing to the preprocessor.
- Moved sources base type to plib to be used for preprocessor includes.
This enables to include e.g. from rom memory regions.
- Renamed some defines
- moved netlists out of driver code into audio/ or machine/ as
nl_xxx.cpp files.
- identified and documented extended validation
- updated arcade, mess and nl targets
- Fix SUBMODEL
- move to strongly typed matrix sort constant
- extend maximum matrix size to 512x512
- optionally do parallel processing based on total operations
- templatize GMRES solver loops
This fixes an over simplification. Logic devices implicitly assumed that
GND/VDD actually is connected to GND(i.e. 0V). There is no immediate
benefit from this change. It is a preparation for the future
scalability. Now all power terminals (typically 7/14, 8/16) have to be
explicitly connected to the supply rails.
Also added a validation mode to the netlist core. This is not
intended for running, but solely to better indentify pins which
are not properly connected.
This effectively reverts b380514764 and
c24473ddff, restoring the state at
598cd52272.
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.
Memory management in plib is now alignment-aware. All allocations
respect c++11 alignas. Selected classes like parray and aligned_vector
also provide hints (__builtin_assume_aligned) to g++ and clang.
The alignment optimizations have little impact on the current use cases.
They only become effective on bigger data processing.
What has a measurable impact is memory pooling. This speeds up netlist
games like breakout and pong by about 5%.
Tested with linux, macosx and windows cross builds. All features are
disabled since I can not rule out they may temporarily break more exotic
builds.
Set USE_MEMPOOL to 1 to try this (max 5% performance increase).
For mingw, there is no alignment support. This triggers -Wattribute
errors which due to -Werror crash the build.
- convert macros to c++ code.
- order of device creation should not depend on std lib.
- some state saving cleanup.
- added support for clang-tidy to makefile.
- modifications triggered by clang-tidy-9.
- Removed dead code.
- nltool now adds a define NLTOOL_VERSION. This can be tested in
netlists. It is used in kidniki to ensure I stop committing
debug parameters.
- Optimized the proposal for no-deactivate hints.
- Documented in breakout that hints were manually optimized.
- Minor optimizations in the order of 2% enhancement.
This is an effort to separate netlist creation from netlist execution.
The primary target is to avoid that code which will only run during
execution is able to call setup code and thus create ugly hacks.
This change removes all string extensions like trim, rpad, left, right,
... from pstring and replaces them by function templates.
This aligns a lot better with the intentions of the standard library.
- more use of c++ features
- some CRTP in pfmtlog
- demangled code for truthtables
- use more constexpr
- rewrite main loop
- use default constructors and assignment operators were applicable.
- optimized 7448 and 9316
All of this has decreased startup time by approx. 25% to 30%. Complex
netlists like pong or kidniki are parsed, analyzed and constructed in
around 15 ms. Run performance has increased by about 5%.
All in all not to bad. A game like pong uses a clock of 7 MHz (after
division by 2). Thats 14 MHz clock invocations. Running at over 200%, 28
MHz. On a 3.9 GHz Machine about 140 cycles/clock change.
[Couriersud]
- Fixed crashes on terminals without nets (i.e. connected to a rail)
- Reviewed "FIXMEs" and corrected some minor ones.
- Made m_cur_analog protected.
- Fixed pmf delegates to work with msvc.
- More optimizations to the solver code.
- Started work on a better signal pipeline in nlwav
- Only generate documentation for entities which are documented.
[Couriersud]
Device implementations (all cpp files in netlist/devices) now should
only include nl_base.h.
Netlist implementation sources should only include "net_lib.h".
Refactored netlist.h and netlist.cpp to avoid namespace congestion in
netlist.h.
Fixed VC2015 build. (nw)
