Constant Folding

Evaluate all expressions which can be evaluated at compile time

    c := add(100, 15)
    a := add(c, 50)
    b := add(b, 10)

Should compiled down to a block which just PUSH's the result of 175 onto the stack.

Test Cases

1. Input Yul

{
    let c:u32 := add(100, 15)
    let a:u32 := sub(c, 50)
    let b:u32 := mul(a, 10)
    let d:u32 := div(b, 2)
}

1. Assembly Output

use.std::math::u256
 
begin
    # Assigning to d #
        # u32 literal 425 #
        push.425
end

2. Input Yul

{
    let c := add(100, 15)
    let a := sub(c, 50)
    let b := mul(a, 10)
    let d := div(b, 2)
}

2. Assembly Output

use.std::math::u256
 
 
begin
    # Assigning to d #
        # u256 literal: 425 #
        push.425        push.0          push.0          push.0          push.0          push.0          push.0          push.0         

end
