Some steps depend on properties ensured by ``BlockFlattener``, ``FunctionGrouper``, ``ForLoopInitRewriter``. Some steps depend on properties ensured by ``BlockFlattener``, ``FunctionGrouper``, ``ForLoopInitRewriter``.
For this reason the Yul optimizer always applies them before applying any steps supplied by the user. For this reason the Yul optimizer always applies them before applying any steps supplied by the user.
The ReasoningBasedSimplifier is an optimizer step that is currently not enabled
in the default set of steps. It uses an SMT solver to simplify arithmetic expressions
and boolean conditions. It has not received thorough testing or validation yet and can produce
non-reproducible results, so please use with care!
