Package vm implements the Ethereum Virtual Machine.
|
|
|
|
The vm package implements two EVMs, a byte code VM and a JIT VM. The BC
|
|
(Byte Code) VM loops over a set of bytes and executes them according to a set
|
|
of rules defined in the Ethereum yellow paper. When the BC VM is invokes it
|
|
invokes the JIT VM in a seperate goroutine and compiles the byte code in JIT
|
|
instructions.
|
|
|
|
The JIT VM, when invoked, loops around a set of pre-defined instructions until
|
|
it either runs of gas, causes an internel error, returns or stops. At a later
|
|
stage the JIT VM will see some additional features that will cause sets of
|
|
instructions to be compiled down to segments. Segments are sets of instructions
|
|
that can be ran in one go saving precious time during execution.
