2007-11-29 Stop infrun from tracking breakpoint insertion status.Vladimir Prus1-44/+17
The checks of breakpoints_inserted before calling remove_breakpoints are removed, as remove_breakpoint won't touch uninserted breakpoints. In a number of places, we're interested if a breakpoint is inserted at particular PC, and we now use breakpoint_inserted_here_p. In a few places, insert_breakpoints can be called unconditionally, since it won't try to insert already inserted breakpoint. * breakpoint.h (regular_breakpoint_inserted_here_p): New declaration. * breakpoint.c (regular_breakpoint_inserted_here_p): New. (breakpoint_inserted_here_p): Use regular_breakpoint_inserted_here_p. * infrun.c (breakpoints_inserted): Remove. (resume): Don't check for breakpoints_inserted before remove_hw_watchpoints. Use breakpoint_inserted_here_p. (proceed, init_wait_for_inferior): Don't set breakpoints_inserted. (handle_inferior_event): Don't use breakpoints_inserted. Use breakpoints_meant_to_be_inserted and breakpoints_inserted_here_p. (insert_step_resume_breakpoint_at_sal, keep_going): Use breakpoints_meant_to_be_inserted. Don't set breakpoints_inserted. (normal_stop): Don't check for breakpoints_inserted. Don't set breakpoints_inserted. (keep_going): Don't check for breakpoints_inserted.
