This repo contains example contracts used to demonstrate the YUL IR-optimizer mechanics.
Change your solc version to the one in the contract by executing
solc-select use <version>
To compile any file run the following command
solc --optimize --ir-optimized -o out contracts/<filename>.sol
The contracts can be found in the contracts folder. Once the file is compiled, you can find the IR-optimized version in the out folder under the filename <filename>_opt.yul
