Question regarding example

[e25519r]

Hello, I was checking out revm and the block traces example.

When I'm summing up the gas_cost of all ops (with a custom Inspector) using a transaction with no calls e.g. WETH.deposit() results to the correct gas usage. initial=21064, instructions=23974 equals expected=45038 for example tx=0x5f0dc1793698b53725b424499ab01d40f3b20b2052faf00851a0d57beed56352.

    fn step_end(&mut self, interp: &mut Interpreter, _context: &mut EvmContext<DB>) {
        let remaining = core::mem::replace(&mut self.remaining, interp.gas.remaining());
        self.total += = remaining.saturating_sub(self.remaining);
    }

Although, when trying transactions that use (DELEGATECALL, CALL ...) the total gas is way higher. initial=23208, instructions=687946 while expected=126582 for example tx=0x2ff4cc105b52a29f5e2f105918c86c2bee14e9e2297d6331365a7efe8c14dada.

I was creating some triggers on JUMPDEST/RETURN,STOP etc or others with context.journaled_state.depth and even if the total was significantly closer, it was never exact.

What would be the best way to get a precise measurement?

Thanks!

Ok, having the json traces showed better whats going on 👍
