History
hrkrshnn 2cdd3b2081 Resolving Keccak-256: check if arguments are identifiers early. 
Previously, the check on whether the optimization was useful gas wise was done before checking if
the keccak256 opcode had identifier as arguments. Since the gas meter crashes when encountering
certain Yul opcodes (create, dataoffset, etc.), this optimizer step crashed.

Yul-Based Optimizer

The documentation of the Yul-based optimizer module has been moved to the official Solidity documentation.

Please refer to the optimizer documentation for a description of all optimization stages and how to use the optimizer and to the Yul documentation for more information on the optimization step sequence and a list of abbreviations for each step.
