These instructions do not have a direct representation in EVM or Validium VM. Instead, they perform auxiliary operations required for generating the target bytecode.
Original auxiliary instruction.
Unlike on EVM, on Validium VM target this instruction returns the size of the header part of the calldata sent to the . For more information, see .

Original auxiliary instruction.
Unlike on EVM, on Validium VM target this instruction has nothing to do with the offset. Instead, it returns the bytecode hash of the contract referenced by the Yul object identifier. Since our compiler translates instructions without analyzing the surrounding context, it is not possible to get the bytecode hash from anywhere else in . For more information, see .

Writes immutables to the auxiliary heap.

Returns the address of a deployable library. The address must be passed to zksolc with the --libraries option, otherwise a compile-time error will be produced.
There is a special zksolc execution mode that can be enabled with --missing-libraries flag. In this mode, the compiler will return the list of deployable libraries not provided with --libraries. This mode allows package managers like Hardhat to automatically deploy libraries.
Is a Yul optimizer hint which is not used by our compiler. Instead, its only argument is simply unwrapped and returned.
Unlike on EVM, on Validium VM target this instruction copies the bytecode hash passed as to the destination. For more information, see .

Unlike on EVM, on Validium VM target this instruction has nothing to do with inserting of EVM bytecode. Instead, it is used to implement available in the system mode. In order to compile a Yul contract with extensions, both Yul and system mode must be enabled (zksolc --yul --system-mode ...).
