 1. If length of transaction data (`initcode`) in a create transaction exceeds `MAX_INITCODE_SIZE`, transaction is invalid. (*Note that this is similar to transactions considered invalid for not meeting the intrinsic gas cost requirement.*)
 2. For a create transaction, extend the transaction data cost formula to include `initcode_cost(initcode)`. (*Note that this is included in transaction intrinsic cost, i.e. transaction with not enough gas to cover initcode cost is invalid.*)
 3. If length of `initcode` to `CREATE` or `CREATE2` instructions exceeds `MAX_INITCODE_SIZE`, instruction execution ends with the result `0` pushed on the stack. Gas for initcode execution is not deducted and caller's nonce is not incremented in this case.

This cost is deducted before the calculation of the resulting contract address and the execution of `initcode`.
