47 | /* This include file defines the interface between the main part |
48 | of the debugger, and the part which is target-specific, or | |
49 | specific to the communications interface between us and the | |
50 | target. | |
51 | ||
2146d243 RM |
52 | A TARGET is an interface between the debugger and a particular |
53 | kind of file or process. Targets can be STACKED in STRATA, | |
c906108c SS |
54 | so that more than one target can potentially respond to a request. |
55 | In particular, memory accesses will walk down the stack of targets | |
56 | until they find a target that is interested in handling that particular | |
57 | address. STRATA are artificial boundaries on the stack, within | |
58 | which particular kinds of targets live. Strata exist so that | |
59 | people don't get confused by pushing e.g. a process target and then | |
60 | a file target, and wondering why they can't see the current values | |
61 | of variables any more (the file target is handling them and they | |
62 | never get to the process target). So when you push a file target, | |
63 | it goes into the file stratum, which is always below the process | |
a1740ee1 PA |
64 | stratum. |
65 | ||
66 | Note that rather than allow an empty stack, we always have the | |
67 | dummy target at the bottom stratum, so we can call the target | |
68 | methods without checking them. */ | |

1913 | /* GDB's current model is that there are three "kinds" of watchpoints, |
1914 | with respect to when they trigger and how you can move past them. | |
1915 | ||
1916 | Those are: continuable, steppable, and non-steppable. | |
1917 | ||
1918 | Continuable watchpoints are like x86's -- those trigger after the | |
1919 | memory access's side effects are fully committed to memory. I.e., | |
1920 | they trap with the PC pointing at the next instruction already. | |
1921 | Continuing past such a watchpoint is doable by just normally | |
1922 | continuing, hence the name. | |
1923 | ||
1924 | Both steppable and non-steppable watchpoints trap before the memory | |
1925 | access. I.e, the PC points at the instruction that is accessing | |
1926 | the memory. So GDB needs to single-step once past the current | |
1927 | instruction in order to make the access effective and check whether | |
1928 | the instruction's side effects change the watched expression. | |
1929 | ||
1930 | Now, in order to step past that instruction, depending on | |
1931 | architecture and target, you can have two situations: | |
1932 | ||
1933 | - steppable watchpoints: you can single-step with the watchpoint | |
1934 | still armed, and the watchpoint won't trigger again. | |
1935 | ||
1936 | - non-steppable watchpoints: if you try to single-step with the | |
1937 | watchpoint still armed, you'd trap the watchpoint again and the | |
1938 | thread wouldn't make any progress. So GDB needs to temporarily | |
1939 | remove the watchpoint in order to step past it. | |
1940 | ||
1941 | If your target/architecture does not signal that it has either | |
1942 | steppable or non-steppable watchpoints via either | |
1943 | target_have_steppable_watchpoint or | |
1944 | gdbarch_have_nonsteppable_watchpoint, GDB assumes continuable | |
