When using TraceDisplay, whats the meaning of the up/down arrow in the beginning of each line?
These are indicators of a PC Discontinuity in the Trace Output. They are implemented with reverence to an address page that would have 0x0 at the top, and 0xFFFFFFFF at the bottom. An up arrow indicates a discontinuity to a lower address. A down arrow indicates a discontinuity to a higher address.
