In existing formalisms, such reasoning typically either fails or is subject to stringent side conditions on formulas (notably .) that significantly impair automation. We suggest two formal syntactic additions that collectively remove the need for such side conditions: first, the

Because of these subtleties, a number of unsound arguments in such proofs have been made over the years..In this work, we address the challenge of bu

We demonstrate the flexibility of Code2Inv by means of two small-scale yet expressive instances: a loop invariant synthesizer for C programs, and a Constrained Horn Clause (CHC) solver.

In so doing, we take a step towards transferring modular, scalable techniques from the world of program verification to bug catching.
