Stephen Anthony 275666b0af The annual copyright year update. 2019-01-01 11:35:51 -03:30
Stephen Anthony ebe18877f9 Fairly large refactoring of RWP functionality.
- abstracted RWP code into Cart base class (only F8SC converted for now)
- RWP now works by analysing RAM accesses before and after each instruction, catching all occurrences

Fixes for compiling without debugger support.

thrust26 1dfc221a1a fixed RWP by using the last access type 2018-12-08 15:51:16 +01:00
Stephen Anthony abfc01b483 Rework trapping on 'read from write port' functionality.
The new code introduces a generic 'EmulationWarning' exception that can
be thrown for any reason.  The RWP functionality has been ported to use
this, with the main benefit that if we ever have to add new exceptional
cases, we no longer need to modify M6502 class; it will pick up on the
new exceptions and pass them to the EmulationWorker as necessary.

Functionally, the RWP stuff works the same as before, just with a
different implementation behind the scenes.

Stephen Anthony d18f11afa2 Remove Serializable::name() method, and all reference to it in state files.
- this both speeds up load/save of state files, and makes them smaller
- affects both on-disk files, and Time Machine functionality

* Allows to revert much of the complexity of my previous fix.

added ZP code tracking
2017-09-16 22:37:19 +02:00
Stephen Anthony 3a02c54b0a Updated FE scheme to that described by the original FE patent application.
- This emulation is much simpler, and takes the scheme from being
esoteric to being a simple hotspot-based scheme
- The original patent application for the FE scheme describes in perfect
detail what is happening, and although the previous code worked, it
was complex and actually hid what was really happening.

Now that the scheme is hotspot-based, the debugger can be extended to
work better with it.  That part comes next.

stephena dd96a80e7e Updated build requirement for Windows to Visual Studio 2015. This allowa to use 'constexpr', which this patch does for a few classes.

unique_ptr.

stephena 9e23bc3580 Some bugs indicated by running Stella through Coverity. Note that many
of these aren't actually bugs per-se, but are to follow good programming
practices.

stephena f539cef173 I decided to turn on '-Weverything' compiler flag in Clang++ to
see what errors are present in the code.  This is the first pass
in cleaning up the errors it found.

stephena 4792b534d5 Fairly large commit, but basically it is only enabling the 'override'
C++11 keyword.  This makes developing/maintaining class hierarchies
more manageable.

stephena e7fb7318fb Bumped version #.
Introduce namespace to class MD5, so the method call is now MD5::hash()
instead of simply MD5().

Added C++11 '= delete' constructors to most classes, to more clearly
indicate the intent of the class.  Note that this isn't absolutely
necessary, but is considered good form.  I will be teaching a C++ class
over the summer using Stella for examples, so it makes sense to follow
the standard and the textbook recommendations :)

Removed constexpr, since VC++ 2013 doesn't support it yet.
