Initcode
¶
Bases: Code
Helper class used to generate initcode for the specified deployment code.
The execution gas cost of the initcode is calculated, and also the deployment gas costs for the deployed code.
The initcode can be padded to a certain length if necessary, which does not affect the deployed code.
Other costs such as the CREATE2 hashing costs or the initcode_word_cost of EIP-3860 are not taken into account by any of these calculated costs.

Opcode

- pushed_stack_items: number of items the opcode pushes to the stack
- min_stack_height: minimum stack height required by the opcode

__new__(opcode_or_byte, *, popped_stack_items=0, pushed_stack_items=0, min_stack_height=0, data_portion_length=0)
¶
Creates a new opcode instance.

46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 |
|
__call__(*args_t)
¶
Makes all opcode instances callable to return formatted bytecode, which constitutes a data portion, that is located after the opcode byte, and pre-opcode bytecode, which is normally used to set up the stack.
This useful to automatically format, e.g., push opcodes and their
data sections as Opcodes.PUSH1(0x00)
.
Data sign is automatically detected but for this reason the range
of the input must be:
[-2^(data_portion_bits-1), 2^(data_portion_bits)]
where:
data_portion_bits == data_portion_length * 8
For the stack, the arguments are set up in the opposite order they are given, so the first argument is the last item pushed to the stack.
The resulting stack arrangement does not take into account opcode stack element consumption, so the stack height is not guaranteed to be correct and the user must take this into consideration.
Integers can also be used as stack elements, in which case they are automatically converted to PUSH operations, and negative numbers always use a PUSH32 operation.
