What4.Interface

Defines interface between the simulator and terms that are sent to the SAT or SMT solver. The simulator can use a richer set of types, but the symbolic values must be representable by types supported by this interface.

A solver backend is defined in terms of a type parameter sym, which is the type that tracks whatever state or context is needed by that particular backend. To instantiate the solver interface, one must provide several type family definitions and class instances for sym:

type SymExpr sym :: BaseType -> *

Type of symbolic expressions.

type BoundVar sym :: BaseType -> *

Representation of bound variables in symbolic expressions.

type SymFn sym :: Ctx BaseType -> BaseType -> *

Representation of symbolic functions.

instance IsExprBuilder sym

Functions for building expressions of various types.

instance IsSymExprBuilder sym

Functions for building expressions with bound variables and quantifiers.

instance IsExpr (SymExpr sym)

Recognizers for various kinds of literal expressions.

instance OrdF (SymExpr sym)

instance TestEquality (SymExpr sym)

instance HashableF (SymExpr sym)

The canonical implementation of these interface classes is found in What4.Expr.Builder.

IsExprBuilder

class (IsExpr (SymExpr sym), HashableF (SymExpr sym), TestEquality (SymAnnotation sym), OrdF (SymAnnotation sym), HashableF (SymAnnotation sym)) => IsExprBuilder sym where

This class allows the simulator to build symbolic expressions.

Methods of this class refer to type families SymExpr sym and SymFn sym.

Note: Some methods in this class represent operations that are partial functions on their domain (e.g., division by 0). Such functions will have documentation strings indicating that they are undefined under some conditions.

The behavior of these functions is generally to throw an error if it is concretely obvious that the function results in an undefined value; but otherwise they will silently produce an unspecified value of the expected type.

Methods

getConfiguration :: sym -> Config

Retrieve the configuration object corresponding to this solver interface.

setSolverLogListener :: sym -> Maybe (SolverEvent -> IO ()) -> IO ()

Install an action that will be invoked before and after calls to backend solvers. This action is primarily intended to be used for logging/profiling/debugging purposes. Passing Nothing to this function disables logging.

getSolverLogListener :: sym -> IO (Maybe (SolverEvent -> IO ()))

Get the currently-installed solver log listener, if one has been installed.

logSolverEvent :: sym -> SolverEvent -> IO ()

Provide the given even to the currently installed solver log listener, if any.

getStatistics :: sym -> IO Statistics

Get statistics on execution from the initialization of the symbolic interface to this point. May return zeros if gathering statistics isn't supported.

getCurrentProgramLoc :: sym -> IO ProgramLoc

Get current location of program for term creation purposes.

setCurrentProgramLoc :: sym -> ProgramLoc -> IO ()

Set current location of program for term creation purposes.

isEq :: sym -> SymExpr sym tp -> SymExpr sym tp -> IO (Pred sym)

Return true if two expressions are equal. The default implementation dispatches eqPred, bvEq, natEq, intEq, realEq, cplxEq, structEq, or arrayEq, depending on the type.

baseTypeIte :: sym -> Pred sym -> SymExpr sym tp -> SymExpr sym tp -> IO (SymExpr sym tp)

Take the if-then-else of two expressions. The default implementation dispatches itePred, bvIte, natIte, intIte, realIte, cplxIte, structIte, or arrayIte, depending on the type.

annotateTerm :: sym -> SymExpr sym tp -> IO (SymAnnotation sym tp, SymExpr sym tp)

Given a symbolic expression, annotate it with a unique identifier that can be used to maintain a connection with the given term. The SymAnnotation is intended to be used as the key in a hash table or map to additional data can be maintained alongside the terms. The returned SymExpr has the same semantics as the arugmnent, but has embedded in it the SymAnnotation value so that it can be used later during term traversals.

Note, the returned annotation is not necessarily fresh; if an already-annotated term is passed in, the same annotation value will be returned.

truePred :: sym -> Pred sym

Constant true predicate

falsePred :: sym -> Pred sym

Constant false predicate

notPred :: sym -> Pred sym -> IO (Pred sym)

Boolean negation

andPred :: sym -> Pred sym -> Pred sym -> IO (Pred sym)

impliesPred :: sym -> Pred sym -> Pred sym -> IO (Pred sym)

xorPred :: sym -> Pred sym -> Pred sym -> IO (Pred sym)

Exclusive-or operation

eqPred :: sym -> Pred sym -> Pred sym -> IO (Pred sym)

Equality of boolean values

itePred :: sym -> Pred sym -> Pred sym -> Pred sym -> IO (Pred sym)

natLit :: sym -> Natural -> IO (SymNat sym)

A natural number literal.

natAdd :: sym -> SymNat sym -> SymNat sym -> IO (SymNat sym)

Add two natural numbers.

natSub :: sym -> SymNat sym -> SymNat sym -> IO (SymNat sym)

Subtract one number from another.

The result is undefined if this would result in a negative number.

natMul :: sym -> SymNat sym -> SymNat sym -> IO (SymNat sym)

Multiply one number by another.

natDiv :: sym -> SymNat sym -> SymNat sym -> IO (SymNat sym)

natDiv sym x y performs division on naturals.

The result is undefined if y equals 0.

natDiv and natMod satisfy the property that given

  d <- natDiv sym x y
  m <- natMod sym x y

and y > 0, we have that y * d + m = x and m < y.

natMod :: sym -> SymNat sym -> SymNat sym -> IO (SymNat sym)

natMod sym x y returns x mod y.

See natDiv for a description of the properties the return value is expected to satisfy.

natIte :: sym -> Pred sym -> SymNat sym -> SymNat sym -> IO (SymNat sym)

If-then-else applied to natural numbers.

natEq :: sym -> SymNat sym -> SymNat sym -> IO (Pred sym)

Equality predicate for natural numbers.

natLe :: sym -> SymNat sym -> SymNat sym -> IO (Pred sym)

If-then-else applied to integers.

intEq :: sym -> SymInteger sym -> SymInteger sym -> IO (Pred sym)

Integer equality.

intLe :: sym -> SymInteger sym -> SymInteger sym -> IO (Pred sym)

Integer less-than-or-equal.

intLt :: sym -> SymInteger sym -> SymInteger sym -> IO (Pred sym)

Integer less-than.

intAbs :: sym -> SymInteger sym -> IO (SymInteger sym)

Compute the absolute value of an integer.

intDiv :: sym -> SymInteger sym -> SymInteger sym -> IO (SymInteger sym)

intDiv x y computes the integer division of x by y. This division is interpreted the same way as the SMT-Lib integer theory, which states that div and mod are the unique Eucledian division operations satisfying the following for all y /= 0:

• x * (div x y) + (mod x y) == x

•  0 <= mod x y < abs y

The value of intDiv x y is undefined when y = 0.

Integer division requires nonlinear support whenever the divisor is not a constant.

Note: div x y is floor (x/y) when y is positive (regardless of sign of x) and ceiling (x/y) when y is negative. This is neither of the more common "round toward zero" nor "round toward -inf" definitions.

Some useful theorems that are true of this division/modulus pair: * mod x y == mod x (- y) == mod x (abs y) * div x (-y) == -(div x y)

intMod :: sym -> SymInteger sym -> SymInteger sym -> IO (SymInteger sym)

intMod x y computes the integer modulus of x by y. See intDiv for more details.

The value of intMod x y is undefined when y = 0.

Integer modulus requires nonlinear support whenever the divisor is not a constant.

intDivisible :: sym -> SymInteger sym -> Natural -> IO (Pred sym)

intDivisible x k is true whenever x is an integer divisible by the known natural number k. In other words `divisible x k` holds if there exists an integer z such that `x = k*z`.

bvUdiv :: 1 <= w => sym -> SymBV sym w -> SymBV sym w -> IO (SymBV sym w)

Unsigned bitvector division.

The result of bvUdiv x y is undefined when y is zero, but is otherwise equal to floor( x / y ).

bvUrem :: 1 <= w => sym -> SymBV sym w -> SymBV sym w -> IO (SymBV sym w)

Unsigned bitvector remainder.

The result of bvUrem x y is undefined when y is zero, but is otherwise equal to x - (bvUdiv x y) * y.

bvSdiv :: 1 <= w => sym -> SymBV sym w -> SymBV sym w -> IO (SymBV sym w)

Signed bitvector division. The result is truncated to zero.

The result of bvSdiv x y is undefined when y is zero, but is equal to floor(x/y) when x and y have the same sign, and equal to ceiling(x/y) when x and y have opposite signs.

NOTE! However, that there is a corner case when dividing MIN_INT by -1, in which case an overflow condition occurs, and the result is instead MIN_INT.

bvSrem :: 1 <= w => sym -> SymBV sym w -> SymBV sym w -> IO (SymBV sym w)

The result of bvSrem x y is undefined when y is zero, but is otherwise equal to x - (bvSdiv x y) * y.
