debugging, verification, symbolic execution




Software debugging for concrete execution enjoys a mature suite of tools, but debugging symbolic execution is still in its infancy. It carries unique challenges, as a single state can lead to multiple branches representing different sets of conditions, and symbolic states must be ’matched’ against logical conditions. Some of today’s otherwise mature symbolic-execution tools still rely on plain-text log files for debugging, which provide no good overview of the execution process and can quickly become overwhelming. We introduce a debugger for Gillian’s verification mode—complete with a custom interface—and ponder the potential for this interface and the protocol behind it to be used outside of Gillian.
