type SEval sym :: Type -> Type Source #

Methods

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

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 ()) Source #

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 -> Maybe (SEval sym a) -> String -> SEval sym (SEval sym a) Source #

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) Source #

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.

sPushFrame :: sym -> Name -> Range -> SEval sym a -> SEval sym a Source #

Push a call frame on to the current call stack while evaluating the given action

sWithCallStack :: sym -> CallStack -> SEval sym a -> SEval sym a Source #

Use the given call stack while evaluating the given action

sModifyCallStack :: sym -> (CallStack -> CallStack) -> SEval sym a -> SEval sym a Source #

Apply the given function to the current call stack while evaluating the given action

-> SEval sym a	The "then" computation
-> SEval sym a	The "else" computation
-> SEval sym a

Merge the two given computations according to the predicate.

assertSideCondition :: sym -> SBit sym -> EvalError -> SEval sym () Source #

Assert that a condition must hold, and indicate what sort of error is indicated if the condition fails.

raiseError :: sym -> EvalError -> SEval sym a Source #

Indiciate that an error condition exists

bitAsLit :: sym -> SBit sym -> Maybe Bool Source #

Determine if this symbolic bit is a boolean literal

Arguments

:: sym
-> SWord sym
-> Integer	Bit position to extract
-> SEval sym (SBit sym)

Extract the numbered bit from the word.

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

wordUpdate Source #

Arguments

:: sym
-> SWord sym
-> Integer	Bit position to update
-> SBit sym
-> SEval sym (SWord sym)

Update the numbered bit in the word.

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) Source #

Construct a word value from a finite sequence of bits. NOTE: this assumes that the sequence of bits is big-endian and finite, so the first element of the list will be the most significant bit.

unpackWord :: sym -> SWord sym -> SEval sym [SBit sym] Source #

Deconstruct a packed word value in to a finite sequence of bits. NOTE: this produces a list of bits that represent a big-endian word, so the most significant bit is the first element of the list.

Arguments

:: sym
-> Integer	bit-width
-> SInteger sym
-> SEval sym (SWord sym)

Construct a packed word of the specified width from an integer value.

joinWord :: sym -> SWord sym -> SWord sym -> SEval sym (SWord sym) Source #

splitWord Source #

Arguments

:: sym
-> Integer	left width
-> Integer	right width
-> SWord sym
-> SEval sym (SWord sym, SWord sym)

Take the most-significant bits, and return those bits and the remainder. The first element of the pair is the most significant bits. The two integer sizes must sum to the length of the given word value.

extractWord Source #

Arguments

:: sym
-> Integer	Number of bits to take
-> Integer	starting bit
-> SWord sym
-> SEval sym (SWord sym)

Extract a subsequence of bits from a packed word value. The first integer argument is the number of bits in the resulting word. The second integer argument is the number of less-significant digits to discard. Stated another way, the operation extractWord n i w is equivalent to first shifting w right by i bits, and then truncating to n bits.
