@ -8,7 +8,7 @@ Compiler Features:
* Yul IR Code Generation: Improved copy routines for arrays with packed storage layout.
* Yul Optimizer: Add rule to convert `mod(mul(X, Y), A)` into `mulmod(X, Y, A)`, if `A` is a power of two.
* Yul Optimizer: Add rule to convert `mod(add(X, Y), A)` into `addmod(X, Y, A)`, if `A` is a power of two.
* Code Generator: More efficient code for checked addition and subtraction.
Bugfixes:
* Commandline Interface: Disallow the following options outside of the compiler mode: ``--via-ir``,``--metadata-literal``, ``--metadata-hash``, ``--model-checker-show-unproved``, ``--model-checker-div-mod-no-slacks``, ``--model-checker-engine``, ``--model-checker-invariants``, ``--model-checker-solvers``, ``--model-checker-timeout``, ``--model-checker-contracts``, ``--model-checker-targets``.
