The Amstrad volunteers itself to be single sided. Everything else stays as it was.

Specifically to resolve an error with shift being pressed at startup due to a failure to establish a default value for that flag, but applying the same principle across the board.

Added the option not to include ready line support in the 6502 core, and took advantage of it in the Electron, Oric and Vic-20 implementations. Also tagged those as forceinline and/or override final where applicable.

Split the static analyser functionality so that it's possible just to ask for the set of media implied by a particular file. Extended ConfigurationTarget so that media alone can be pushed to a machine.

Moves the Electron implementation behind a more opaque interface, in line with changes elsewhere.

Expanded interface so that an external machine caller can request a string be typed without any knowledge of whatever it intends to do re: CharacterMappers. Which is immediately useful in paste functionality.

Within the Typer framework: hatched out CharacterMapper as a distinct thing from the target for keypresses, better to formalise responsibility but also to make it easy cleanly to sever that stuff into its own little part.

Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty.

Brought Typer into the new run_for orthodoxy, making it easier to clock consistently regardless of unit. Which necessitated adding a negative operator for WrappedInts.

Thomas Harte
9ef232157b
Revoked the operator bool() on WrappedInt as providing an indirect means for implicit but incorrect assignment to unwrapped ints. Got explicit about run_for intention and simplified HalfClockReceiver slightly by building a lossy and a flushing conversion to Cycles into HalfCycles. Adapted the all-RAM Z80 properly to return HalfCycles.

Switched definitively to the works-for-now approach of requiring an explicit opt-in where somebody wants to clock a whole-cycle receiver from a half-cycle clock.

Added explicit signedness cast.

Switched to Cycles as the result from the 6502 perform_bus_operation, helping slightly to clarify what you're intended to return and reducing type jumping within the 6502 implementation.

Relocated ClockReceiver.hpp as it's a dependency for parts of the static analyser, and therefore needs to be distinct from the actual emulation parts.

Eliminated redundant uses of ClockReceiver and sought to ensure that proper run_fors are inherited all the way down.

Clean ups along the Electron::Tape line: ensured that the ClockReceiver is opted into only once, and that its run_for propagates all the way along the chain.

Formalised the use of a cycles count with a divider, bringing a few additional plain-int users into the fold.

Reduced int/Cycle conversions in the Electron and on the Atari 2600, where the current framework makes it possible to do so.

Switched CRTMachine over to use Cycles as an explicit statement of units, and followed through on the effects of that.

Factored out the table-lookup approach to being a typer, and adjusted so as definitely to limit myself to positive offset table lookups.

Abstracted the concept of an Acorn shifter away from being a PLLParser. The Acorn tape parser now skips using that class and uses the shifter. The actual Electron also uses the shifter. So the two are completely aligned. Net result: the Electron should successfully load exactly when static analysis was successful.

Oh yuck, it looks like I've repeated this same test in two different places. Must figure out where to factor it out to. But in the meantime, the emulated Electron has just loaded its first CSW.

Settled definitively on flush as more communicative than synchronise (and slightly more locale neutral); culled some more duplication from the Z80.

Pulled the 6502 into a CPU namespace, making it an instance of something that has micro-opcodes and schedules them, and factoring out the formulation of a register pair.

Resolved spurious static analyser issue; screen mode will always be 0–6 but it doesn't know that. Setting a non-zero divider doesn't feel worth worrying about for a cleaner compile.
