- /* This include file defines the interface between the main part
- of the debugger, and the part which is target-specific, or
- specific to the communications interface between us and the
- target.
-
- A TARGET is an interface between the debugger and a particular
- kind of file or process. Targets can be STACKED in STRATA,
- so that more than one target can potentially respond to a request.
- In particular, memory accesses will walk down the stack of targets
- until they find a target that is interested in handling that particular
- address. STRATA are artificial boundaries on the stack, within
- which particular kinds of targets live. Strata exist so that
- people don't get confused by pushing e.g. a process target and then
- a file target, and wondering why they can't see the current values
- of variables any more (the file target is handling them and they
- never get to the process target). So when you push a file target,
- it goes into the file stratum, which is always below the process
- stratum. */

- distinguishing between various kinds of SIGSEGV, or not
- distinguishing hitting a breakpoint from finishing a single step).
