+       * linux-low.c (linux_wait_1): Avoid setting need_step_over is
+       there's a GDB breakpoint at stop_pc.  Always report a trap to GDB
+       if we could tell there's a GDB breakpoint at stop_pc.
+       (need_step_over_p): Don't do a step over if we find a GDB
+       breakpoint at the resume PC.
+
+       * mem-break.c (struct raw_breakpoint): New.
+       (enum bkpt_type): New type `gdb_breakpoint'.
+       (struct breakpoint): Delete the `PC', `old_data' and `inserted'
+       fields.  New field `raw'.
+       (find_raw_breakpoint_at): New.
+       (set_raw_breakpoint_at): Handle refcounting.  Create a raw
+       breakpoint instead.

+       (delete_raw_breakpoint): New.
+       (release_breakpoint): New.
+       (delete_breakpoint): Rename to...
+       (delete_breakpoint_1): ... this.  Add proc parameter.  Use
+       release_breakpoint.  Return ENOENT.
+       (delete_breakpoint): Reimplement.
+       (find_breakpoint_at): Delete.
+       (find_gdb_breakpoint_at): New.
+       (delete_breakpoint_at): Delete.

+       (gdb_breakpoint_here): New.
+       (set_reinsert_breakpoint): Use release_breakpoint.
+       (uninsert_breakpoint): Rename to ...
+       (uninsert_raw_breakpoint): ... this.
+       (uninsert_breakpoints_at): Adjust to handle raw breakpoints.
+       (reinsert_raw_breakpoint): Change parameter type to
+       raw_breakpoint.
+       (reinsert_breakpoints_at): Adjust to handle raw breakpoints
+       instead.
+       (check_breakpoints): Adjust.  Use release_breakpoint.
+       (breakpoint_here): Rewrite using find_raw_breakpoint_at.
+       (breakpoint_inserted_here): Ditto.
+       (check_mem_read): Adjust to iterate over raw breakpoints instead.
+       Don't trust the breakpoint's shadow if it is not inserted.
+       (check_mem_write): Adjust to iterate over raw breakpoints instead.
+       (delete_all_breakpoints): Adjust.
+       (free_all_breakpoints): Mark all breakpoints as uninserted, and
+       use delete_breakpoint_1.
+
+       * mem-break.h (breakpoints_supported): Delete declaration.
+       (set_gdb_breakpoint_at): Declare.
+       (gdb_breakpoint_here): Declare.
+       (delete_breakpoint_at): Delete.
+       (delete_gdb_breakpoint_at): Declare.
+
