GenericValue

data GenValue sym

Generic value type, parameterized by bit and word types.

NOTE: we maintain an important invariant regarding sequence types. VSeq must never be used for finite sequences of bits. Always use the VWord constructor instead! Infinite sequences of bits are handled by the VStream constructor, just as for other types.

Methods

isReady :: sym -> SEval sym a -> Bool

Check if an operation is "ready", which means its evaluation will be trivial.

sDeclareHole :: sym -> String -> SEval sym (SEval sym a, SEval sym a -> SEval sym ())

Produce a thunk value which can be filled with its associated computation after the fact. A preallocated thunk is returned, along with an operation to fill the thunk with the associated computation. This is used to implement recursive declaration groups.

sDelayFill :: sym -> SEval sym a -> SEval sym a -> SEval sym (SEval sym a)

Delay the given evaluation computation, returning a thunk which will run the computation when forced. Run the retry computation instead if the resulting thunk is forced during its own evaluation.

sSpark :: sym -> SEval sym a -> SEval sym (SEval sym a)

Begin evaluating the given computation eagerly in a separate thread and return a thunk which will await the completion of the given computation when forced.

Arguments

:: sym

-> SWord sym

-> Integer

Bit position to extract

-> SEval sym (SBit sym)

NOTE: this assumes that the sequence of bits is big-endian and finite, so the bit numbered 0 is the most significant bit.

wordUpdate

Arguments

:: sym

-> SWord sym

-> Integer

Bit position to update

-> SBit sym

-> SEval sym (SWord sym)

NOTE: this assumes that the sequence of bits is big-endian and finite, so the bit numbered 0 is the most significant bit.

packWord :: sym -> [SBit sym] -> SEval sym (SWord sym)

largeBitSize :: Integer

WordValue

data WordValue sym

For efficiency reasons, we handle finite sequences of bits as special cases in the evaluator. In cases where we know it is safe to do so, we prefer to used a "packed word" representation of bit sequences. This allows us to rely directly on Integer types (in the concrete evaluator) and SBV's Word types (in the symbolic simulator).

However, if we cannot be sure all the bits of the sequence will eventually be forced, we must instead rely on an explicit sequence of bits representation.

Constructors

WordVal !(SWord sym)

Packed word representation for bit sequences.

LargeBitsVal !Integer !(SeqMap sym)

A large bitvector sequence, represented as a SeqMap of bits.
