Return

---

STOP

Original EVM instruction.

This instruction is a RETURN with an empty data payload.

LLVM IR

The same as for RETURN.

The LLVM IR generator code is common for Yul and EVMLA representations.

RETURN

Original EVM instruction.

This instruction works differently in deploy code. For more information, see the ZKsync Era documentation.

LLVM IR

define void @__return(i256 %0, i256 %1, i256 %2) "noinline-oz" #5 personality i32()* @__personality {
entry:
  %abi = call i256@__aux_pack_abi(i256 %0, i256 %1, i256 %2)
  tail call void @llvm.syncvm.return(i256 %abi)
  unreachable
}

The LLVM IR generator code is common for Yul and EVMLA representations.

REVERT

Original EVM instruction.

LLVM IR

define void @__revert(i256 %0, i256 %1, i256 %2) "noinline-oz" #5 personality i32()* @__personality {
entry:
  %abi = call i256@__aux_pack_abi(i256 %0, i256 %1, i256 %2)
  tail call void @llvm.syncvm.revert(i256 %abi)
  unreachable
}

The LLVM IR generator code is common for Yul and EVMLA representations.

INVALID

Original EVM instruction.

This instruction is a REVERT with an empty data payload, but it also burns all the available gas.

LLVM IR

The same as for REVERT.

The LLVM IR generator code is common for Yul and EVMLA representations.
