- at the old thread's pc location, then switch to that thread
- and return TRUE, else return FALSE and don't do a thread
- switch (or rather, don't seem to have done a thread switch).
-
- Ptrace-based gdb will always return FALSE to the thread-switch
- query, and thus also to PREPARE_TO_PROCEED.
-
- The important thing is whether there is a BPT instruction,
- not how many user breakpoints there are. So we have to worry
- about things like these:
-
- o Non-bp stop -- NO
-
- o User hits bp, no switch -- NO
-
- o User hits bp, switches threads -- YES
-
- o User hits bp, deletes bp, switches threads -- NO
-
- o User hits bp, deletes one of two or more bps
- at that PC, user switches threads -- YES
-
- o Plus, since we're buffering events, the user may have hit a
- breakpoint, deleted the breakpoint and then gotten another
- hit on that same breakpoint on another thread which
- actually hit before the delete. (FIXME in breakpoint.c
- so that "dead" breakpoints are ignored?) -- NO
-
- For these reasons, we have to violate information hiding and
- call "breakpoint_here_p". If core gdb thinks there is a bpt
- here, that's what counts, as core gdb is the one which is
- putting the BPT instruction in and taking it out.
-

- default_prepare_to_proceed() has been added.
