Dead Memory

If a value is stored in memory, once it's location is never read from again the compiler can consider that memory as "free," and overwrite it

Test Cases

Yul Input

{
    let x:u32 := 700
    mstore(0x100, x)

    let z := mload(0x100)
    let y:u32 := 100

    let a := add(z, y)
    mstore(0x200, a)
}

Assembly Output

//Should store `a` at memory slot 0x100
