* core/vm: reuse Keccak-256 hashes across opcode executions (#17863)Péter Szilágyi2018-10-081-1/+15
|
* core/vm: add switches to select evm+ewasm interpreters (#17687)Guillaume Ballet2018-09-201-0/+5
| | | | | Interpreter initialization is left to the PRs implementing them. Options for external interpreters are passed after a colon in the `--vm.ewasm` and `--vm.evm` switches.
* core/vm: Hide read only flag from Interpreter interface (#17461)Paweł Bylica2018-09-081-16/+9
| | | | | Makes Interface interface a bit more stateless and abstract. Obviously this change is dictated by EVMC design. The EVMC tries to keep the responsibility for EVM features totally inside the VMs, if feasible. This makes VM "stateless" because VM does not need to pass any information between executions, all information is included in parameters of the execute function.
* core/vm: support for multiple interpreters (#17093)Guillaume Ballet2018-07-251-7/+46
| | | | | | - Define an Interpreter interface - One contract can call contracts from other interpreter types. - Pass the interpreter to the operands instead of the evm. This is meant to prevent type assertions in operands.
* core/vm: reuse bigint pools across transactions (#17070)Guillaume Ballet2018-07-031-1/+11

* core/vm: track 63/64 call gas off stack (#15563)Felix Lange2017-11-291-18/+10
| | | | | | | | | | | | | | | | | * core/vm: track 63/64 call gas off stack Gas calculations in gasCall* relayed the available gas for calls by replacing it on the stack. This lead to inconsistent traces, which we papered over by copying the pre-execution stack in trace mode. This change relays available gas using a temporary variable, off the stack, and allows removing the weird copy. * core/vm: remove stackCopy * core/vm: pop call gas into pool * core/vm: to -> addr
* build: enable unconvert linter (#15456)ferhat elmas2017-11-111-2/+2

* consensus, core/*, params: metropolis preparation refactorJeffrey Wilcke2017-05-181-30/+50
| | | | | | | | | | | | | | | | | | | | | | | | This commit is a preparation for the upcoming metropolis hardfork. It prepares the state, core and vm packages such that integration with metropolis becomes less of a hassle. * Difficulty calculation requires header instead of individual parameters * statedb.StartRecord renamed to statedb.Prepare and added Finalise method required by metropolis, which removes unwanted accounts from the state (i.e. selfdestruct) * State keeps record of destructed objects (in addition to dirty objects) * core/vm pre-compiles may now return errors * core/vm pre-compiles gas check now take the full byte slice as argument instead of just the size * core/vm now keeps several hard-fork instruction tables instead of a single instruction table and removes the need for hard-fork checks in the instructions * core/vm contains a empty restruction function which is added in preparation of metropolis write-only mode operations * Adds the bn256 curve * Adds and sets the metropolis chain config block parameters (2^64-1)
* core/vm: use uint64 instead of *big.Int in tracer (#3805)Yohann Leon2017-03-221-6/+2

* params: core, core/vm, miner: 64bit gas instructionsJeffrey Wilcke2017-02-141-0/+208
| | | | | | | | | | | | | | | | | Reworked the EVM gas instructions to use 64bit integers rather than arbitrary size big ints. All gas operations, be it additions, multiplications or divisions, are checked and guarded against 64 bit integer overflows. In additon, most of the protocol paramaters in the params package have been converted to uint64 and are now constants rather than variables. * common/math: added overflow check ops * core: vmenv, env renamed to evm * eth, internal/ethapi, les: unmetered eth_call and cancel methods * core/vm: implemented big.Int pool for evm instructions * core/vm: unexported intPool methods & verification methods * core/vm: added memoryGasCost overflow check and test
