52/* This include file defines the interface between the main part
53 of the debugger, and the part which is target-specific, or
54 specific to the communications interface between us and the
55 target.
56
57 A TARGET is an interface between the debugger and a particular
58 kind of file or process. Targets can be STACKED in STRATA,
59 so that more than one target can potentially respond to a request.
60 In particular, memory accesses will walk down the stack of targets
61 until they find a target that is interested in handling that particular
62 address. STRATA are artificial boundaries on the stack, within
63 which particular kinds of targets live. Strata exist so that
64 people don't get confused by pushing e.g. a process target and then
65 a file target, and wondering why they can't see the current values
66 of variables any more (the file target is handling them and they
67 never get to the process target). So when you push a file target,
68 it goes into the file stratum, which is always below the process
69 stratum.
70
71 Note that rather than allow an empty stack, we always have the
72 dummy target at the bottom stratum, so we can call the target
73 methods without checking them. */

1982 with respect to when they trigger and how you can move past them.
1983
1984 Those are: continuable, steppable, and non-steppable.
1985
1986 Continuable watchpoints are like x86's -- those trigger after the
1987 memory access's side effects are fully committed to memory. I.e.,
1988 they trap with the PC pointing at the next instruction already.
1989 Continuing past such a watchpoint is doable by just normally
1990 continuing, hence the name.
1991
1992 Both steppable and non-steppable watchpoints trap before the memory
1993 access. I.e, the PC points at the instruction that is accessing
1994 the memory. So GDB needs to single-step once past the current
1995 instruction in order to make the access effective and check whether
1996 the instruction's side effects change the watched expression.
1997
1998 Now, in order to step past that instruction, depending on
1999 architecture and target, you can have two situations:
2000
2001 - steppable watchpoints: you can single-step with the watchpoint
2002 still armed, and the watchpoint won't trigger again.
2003
2004 - non-steppable watchpoints: if you try to single-step with the
2005 watchpoint still armed, you'd trap the watchpoint again and the
2006 thread wouldn't make any progress. So GDB needs to temporarily
2007 remove the watchpoint in order to step past it.
2008
2009 If your target/architecture does not signal that it has either
2010 steppable or non-steppable watchpoints via either
2011 target_have_steppable_watchpoint or
2012 gdbarch_have_nonsteppable_watchpoint, GDB assumes continuable
