+       * breakpoint.c (need_moribund_for_location_type): New function.
+       (bpstat_stop_status): Don't skipping checking moribund locations
+       of breakpoint types which the target tell caused a stop.
+       (program_breakpoint_here_p): New function, factored out from ...
+       (bp_loc_is_permanent): ... this.
+       (update_global_location_list): Don't create a moribund location if
+       the target supports reporting stops of the type of the removed
+       breakpoint.
+       * breakpoint.h (program_breakpoint_here_p): New declaration.
+       * infrun.c (adjust_pc_after_break): Return early if the target has
+       already adjusted the PC.  Add comments.
+       (handle_signal_stop): If nothing explains a signal, and the target
+       tells us the stop was caused by a software breakpoint, check if
+       there's a breakpoint instruction in the memory.  If so, adjust the
+       PC before presenting the stop to the user.  Otherwise, ignore the
+       trap.  If nothing explains a signal, and the target tells us the
+       stop was caused by a hardware breakpoint, ignore the trap.
+       * target.h (struct target_ops) <to_stopped_by_sw_breakpoint,
+       to_supports_stopped_by_sw_breakpoint, to_stopped_by_hw_breakpoint,
+       to_supports_stopped_by_hw_breakpoint>: New fields.

+       (target_stopped_by_hw_breakpoint)
