Turn on IR optimizer

[guidanoli]

📚 Context

The Solidity compiler comes with an IR optimized that is turned off by default.
This optimizer can improve gas costs of function calls and contract size.
After doing a quick experiment with Via-IR, I've observed significant reductions on both metrics.
Here are some functions with significant gas cost improvements (median discrepancy):

• ApplicationFactory.newApplication: -20.5%
• SelfHostedApplicationFactory.deployContracts: -9.1%
• Application.validateOutput: -9.7%
• Application.executeOutput: -2.6%

✔️ Solution

Turn Via-IR on foundry.toml and hardhat.config.ts.
