The bulk of this PR is authored by @lightclient , in the original EOF-work. More recently, the code has been picked up and reworked for the new EOF specification, by @MariusVanDerWijden , in https://github.com/ethereum/go-ethereum/pull/29518, and also @shemnon has contributed with fixes. This PR is an attempt to start eating the elephant one small bite at a time, by selecting only the eof-validation as a standalone piece which can be merged without interfering too much in the core stuff. In this PR: - [x] Validation of eof containers, lifted from #29518, along with test-vectors from consensus-tests and fuzzing, to ensure that the move did not lose any functionality. - [x] Definition of eof opcodes, which is a prerequisite for validation - [x] Addition of `undefined` to a jumptable entry item. I'm not super-happy with this, but for the moment it seems the least invasive way to do it. A better way might be to go back and allowing nil-items or nil execute-functions to denote "undefined". - [x] benchmarks of eof validation speed --------- Co-authored-by: lightclient <lightclient@protonmail.com> Co-authored-by: Marius van der Wijden <m.vanderwijden@live.de> Co-authored-by: Danno Ferrin <danno.ferrin@shemnon.com>
