We were previously mixing bits of eth mainnet, cdk-erigon, etc...

Now the prover (i.e. evm_arithmetization) supports 3 network features:

  • eth_mainnet (by default for now): full Ethereum equivalence, Cancun HF
  • polygon_pos: Prunes the ignored bits of Cancun from Napoli upgrade1 and supports incoming PIP-302
  • cdk_erigon: Prunes the ignored bits of Cancun irrelevant for CDK, includes LxLy pre-state execution3 and (yet unimplemented) post-state execution4, as well as the EIP-1559 variant for L2s.

Notes:

  • Removed the parallel feature (as we will always want it enabled, and this allows to not mess up when calling --no-default-features to change network)
  • Commented out the bls12 Kernel file as being unused at the moment
  • Tweaked all integration tests (apart from global_exit_root) to run under eth_mainnet feature flag.

Based on #594

closes #575
closes #563

Looks good, thanks!

Nit: I think an invalid instruction will be caught elsewhere anyway, so we don't need to make a distinction here.

It seems weird to me to have BYTES 1 lying around for an instruction that doesn't exist. Even though as you point this would get caught elsewhere, I think we'd rather not have invalid Kernel bits if we have workarounds

Nit: is there no way to panic here in a const?

You can't compile if you do not have a usize (like if you were to rely on unreachable!() for instance), and I didn't want to have the else only be equivalent to the last network feature in case we were to add another chain later on (as it would easily mess things up)

Can't we just put the entire section concerning the burn address behind this cfg?

This would require to conditionally remove this field from PublicValuesTarget but I think we'd prefer keep it consistent with the non target version
