Jeffrey Wilcke	361082ec4b	cmd/evm, core/vm, test: refactored VM and core ... * Moved `vm.Transfer` to `core` package and changed execution to call `env.Transfer` instead of `core.Transfer` directly. * core/vm: byte code VM moved to jump table instead of switch * Moved `vm.Transfer` to `core` package and changed execution to call `env.Transfer` instead of `core.Transfer` directly. * Byte code VM now shares the same code as the JITVM * Renamed Context to Contract * Changed initialiser of state transition & unexported methods * Removed the Execution object and refactor `Call`, `CallCode` & `Create` in to their own functions instead of being methods. * Removed the hard dep on the state for the VM. The VM now depends on a Database interface returned by the environment. In the process the core now depends less on the statedb by usage of the env * Moved `Log` from package `core/state` to package `core/vm`.	9 years ago
Jeffrey Wilcke	32395ddb89	core/vm: fixed jit error & added inline docs ... opNumber did not create a new big int which could lead to the block's number being modified.	9 years ago
Jeffrey Wilcke	ac697326a6	core/vm: reduced big int allocations ... Reduced big int allocation by making stack items modifiable. Instead of adding items such as `common.Big0` to the stack, `new(big.Int)` is added instead. One must expect that any item that is added to the stack might change.	9 years ago
Jeffrey Wilcke	184e9ae9a8	core, tests: reduced state copy by N calls ... Reduced the amount of state copied that are required by N calls by doing a balance check prior to any state modifications.	9 years ago
Jeffrey Wilcke	846f34f78b	core/vm, tests: implemented semi-jit vm ... * changed stack and removed stack ptr. Let go decide on slice reuse.	9 years ago
