functions well, but lacks full integration. It is not yet properly packaged for the Ghidra functions, but lacks full integration. In particular, Ghidra's concept of time is not
distribution, but is available in development environments. It also needs some additional mapped directly to the TTD concept of time. TTD uses a major/minor scheme for ordering events,
protocol support, namely to integrate its notion of time travel with Ghidra's notion. For the where the major index changes when TTD must record a change in state. Events, including thread
time being, we map our time specifications as follows. MS TTD uses a tuple for its time specs, creation/termination, module loads/unloads, syscalls, and other asynchronous changes, merit
both displayed in hexadecimal, e.g., "B5:1A". The first is the "major," which we believe counts new major indices. When you step forward or backward in a trace, the dbgeng API will increment
the events that warrant a snapshot. The second is the "minor," which we believe counts and decrement correspondingly. Ghidra, on the other hand, will only increment.</P>
instructions executed since the major event. Thus, we would like to map the major to a Ghidra
trace snapshot and the minor to steps of p-code emulation. For example, the "B5:1A" notation
would map to "181:26". It should be no surprise the notations are similar, since both MS TTD
and Ghidra (as well as several other "timeless" debuggers) use a snapshot-replay strategy to
recover past machine states. However, we have not yet worked out how to have Ghidra cooperate
with a back end in the replay part of this strategy. Currently, Ghidra will always apply p-code
emulation, despite having a perfectly good and performant back end available. So, for the time
being, we multiply the major number by 1000, thus reserving that many Ghidra snapshots between
major events for MS TTD minor steps. Thus, the notation "B5:1A" will actually map to "181026",
that is snapshot 181026 with no steps of p-code emulation. This hack will fall short if you
visit a time where the minor number exceeds 999.</P>
<P>Furthermore, if you use the Ghidra Debugger UI to visit a past snapshot, the back end is not
yet informed of your intent. You will probably only see stale records of the machine state.
Instead, please use the kd commands from the Terminal to navigate through time. The back end
(MS TTD) will perform the replay, record the snapshot, and command Ghidra to navigate
there.</P>
