Used by executive to build VM traces.

Required Methods

Spawn subtracer which will be used to trace deeper levels of execution.

Spawn subtracer which will be used to trace deeper levels of execution.

Consumes self and returns the VM trace.

Provided Methods

Trace the preparation to execute a single instruction. @returns true if trace_executed should be called.

Trace the finalised execution of a single instruction.
