goto-synthesizer - Man Page

Synthesize and apply loop contracts of goto binaries.

Synopsis

goto-synthesizer [-?] [-h] [--help]: show help
goto-synthesizer --version: show version and exit
goto-synthesizer [options] in [out]: perform synthesis and loop-contracts transformation

Description

goto-synthesis reads a GOTO binary, performs loop-contracts synthesis and program transformation for the synthesized contracts, and then writes the resulting program as GOTO binary on disk.

Options

-loop-contracts-no-unwind: do not unwind transformed loops after applying the synthesized loop contracts
--dump-loop-contracts: dump the synthesized loop contracts as JSON
--json-output file: specify the output destination of the loop-contracts JSON

Accepts all of cbmc's options plus the following backend options

--object-bits n

number of bits used for object addresses

--sat-solver solver

use specified SAT solver

--external-sat-solver cmd

command to invoke SAT solver process

--no-sat-preprocessor

disable the SAT solver's simplifier

--dimacs

generate CNF in DIMACS format

--beautify

beautify the counterexample (greedy heuristic)

--smt1

use default SMT1 solver (obsolete)

--smt2

use default SMT2 solver (Z3)

--bitwuzla

use Bitwuzla

--boolector

use Boolector

--cprover-smt2

use CPROVER SMT2 solver

use CVC3

use CVC4

use CVC5

use MathSAT

use Yices

use Z3

use theory of floating-point arithmetic

--refine

use refinement procedure (experimental)

--refine-arrays

use refinement for arrays only

--refine-arithmetic

refinement of arithmetic expressions only

--max-node-refinement

maximum refinement iterations for arithmetic expressions

--incremental-smt2-solver cmd

Use the incremental SMT backend where cmd is the command to invoke the SMT solver of choice.
Example invocations:
--incremental-smt2-solver 'z3 -smt2 -in' (use the Z3 solver).
--incremental-smt2-solver 'cvc5 --lang=smtlib2.6 --incremental' (use the CVC5 solver).

Note that:
The solver name must be in the "PATH" or be an executable with full path.
The SMT solver should accept incremental SMTlib v2.6 formatted input from the stdin.
The SMT solver should support the QF_AUFBV logic.
