LibOpIfNP

Git Source

Opcode to choose between two values based on a condition. If is eager, meaning both values are evaluated before the condition is checked.

Functions

integrity

function integrity(IntegrityCheckStateNP memory, Operand) internal pure returns (uint256, uint256);

run

IF IF is a conditional. If the first item on the stack is nonero, the second item is returned, else the third item is returned.

function run(InterpreterStateNP memory, Operand, Pointer stackTop) internal pure returns (Pointer);

referenceFn

Gas intensive reference implementation of IF for testing.

function referenceFn(InterpreterStateNP memory, Operand, uint256[] memory inputs)
    internal
    pure
    returns (uint256[] memory outputs);
