Division and Modulo With Slack Variables
|
||||||
|
========================================
|
||||||
|
|
||||||
|
Spacer, the default Horn solver used by the SMTChecker, often dislikes division
|
||||||
|
and modulo operations inside Horn rules. Because of that, by default the
|
||||||
|
Solidity division and modulo operations are encoded using the constraint
|
||||||
|
``a = b * d + m`` where ``d = a / b`` and ``m = a % b``.
|
||||||
|
However, other solvers, such as Eldarica, prefer the syntactically precise operations.
|
||||||
|
The command line flag ``--model-checker-div-mod-no-slacks`` and the JSON option
|
||||||
|
``settings.modelChecker.divModNoSlacks`` can be used to toggle the encoding
|
||||||
|
depending on the used solver preferences.
