* move forks constants, rename errors * Move vm/utils to vm/interpreter/utils * initial opcodes refactoring * Add refactored Comparison & Bitwise Logic Operations * Add sha3 and address, simplify macro, support pop 0 * balance, origin, caller, callValue * fix gas copy opcodes gas costs, add callDataLoad/Size/Copy, CodeSize/Copy and gas price opcode * Update with 30s, 40s, 50s opcodes + impl of balance + stack improvement * add push, dup, swap, log, create and call operations * finish opcode implementation * Add the new dispatching logic * Pass the opcode test * Make test_vm_json compile * halt execution without exceptions for Return, Revert, selfdestruct (fix #62) * Properly catch and recover from EVM exceptions (stack underflow ...) * Fix byte op * Fix jump regressions * Update for latest devel, don't import old dispatch code as quasiBoolean macro is broken by latest devel * Fix sha3 regression on empty memory slice and until end of range slice * Fix padding / range error on expXY_success (gas computation left) * update logging procs * Add tracing - expXY_success is not a regression, sload stub was accidentally passing the test * Reuse the same stub as OO implementation * Delete previous opcode implementation * Delete object oriented fork code * Delete exceptions that were used as control flows * delete base.nim 🔥, yet another OO remnants * Delete opcode table * Enable omputed gotos and compile-time gas fees * Revert const gasCosts -> generates SIGSEGV * inline push, swap and dup opcodes * loggers are now template again, why does this pass new tests? * Trigger CI rebuild after rocksdb fix https://github.com/status-im/nim-rocksdb/pull/5 * Address review comment on "push" + VMTests in debug mode (not release) * Address review comment: don't tag fork by default, make opcode impl grepable * Static compilation fixes after rebasing * fix the initialization of the VM database * add a missing import * Deactivate balance and sload test following #59 * Reactivate stack check (deactivated in #59, necessary to pass tests) * Merge remaining opcodes implementation from #59 * Merge callDataLoad and codeCopy fixes, todo simplify see #67
