This defines common definitions used in writing SMTLIB (2.0 and later), and
yices outputs from Expr
values.
The writer is designed to support solvers with arithmetic, propositional logic, bitvector, tuples (aka. structs), and arrays.
It maps complex Expr values to either structs or arrays depending on what the solver supports (structs are preferred if both are supported).
It maps multi-dimensional arrays to either arrays with structs as indices if structs are supported or nested arrays if they are not.
The solver should detect when something is not supported and give an error rather than sending invalid output to a file.

:: SMTWriter h | |
=> WriterConn t h | Connection to SMT solver. |
-> SMTEvalFunctions h | |
-> IO (GroundEvalFn t) |
The function creates a function for evaluating elts to concrete values given a connection to an SMT solver along with some functions for evaluating different types of terms to concrete values.
data CollectorResults h a Source #
This describes the result that was collected from the solver.

mkBaseExpr :: SMTWriter h => Expr t tp -> SMTCollector t h (Term h) Source #
Convert an element to a base expression.
runInSandbox :: SupportTermOps (Term h) => WriterConn t h -> SMTCollector t h a -> IO (CollectorResults h a) Source #
This runs the side collector and collects the results.
