The release also improves the performance of the DataFlowAnalyzer, which several Yul optimizer steps are built on. As a result, compilation with the Yul optimizer enabled is faster.
In the IR pipeline, the function dispatcher now uses one fewer instruction.
The compiler now warns when swapn, dupn or exchange is used as an identifier in Yul or inline assembly.
EIP-8024 adds opcodes with these names in the Amsterdam upgrade, and the names become reserved starting from the Amsterdam EVM version. Solidity identifiers are not affected.
