(watchpoints_triggered): Iterate over locations. (bpstat_stop_status): Use only first location of a resource watchpoint. (delete_breakpoint): Don't call free_valchain. (print_one_breakpoint): Don't print all locations for watchpoints. (breakpoint_re_set_one): Use update_watchpoint for watchpoints.

2007-12-13Remove unused support for target-based exception catching.Jim Blandy1-7/+0

(target_enable_exception_callback) (target_get_current_exception_event): Delete macros. * target.c (update_current_target): Remove code to inherit and default those members. (debug_to_enable_exception_callback) (debug_to_get_current_exception_event): Delete functions. (setup_target_debug): Don't install those methods. * inf-child.c (inf_child_enable_exception_callback) (inf_child_get_current_exception_event): Delete dummy functions. (inf_child_target): Don't install them in the target vector. * breakpoint.h (enum bptype): Delete bp_catch_catch, bp_catch_throw. * breakpoint.c (cover_target_enable_exception_callback) (ep_is_exception_catchpoint, create_exception_catchpoint): Delete functions. (insert_bp_location, update_breakpoints_after_exec) (remove_breakpoint, ep_is_catchpoint, print_it_typical) (bpstat_stop_status, bpstat_what) (bpstat_get_triggered_catchpoints, print_one_breakpoint_location) (user_settable_breakpoint, allocate_bp_location) (disable_watchpoints_before_interactive_call_start) (enable_watchpoints_after_interactive_call_stop, mention) (delete_breakpoint, breakpoint_re_set_one, disable_command) (enable_command): Remove exception catchpoint cases.

2007-11-30 Make insert_breakpoints return void.Vladimir Prus1-1/+1
* breakpoint.h (insert_breakpoints): Change return type to void. * breakpoint.c (insert_breakpoints): Change return type to void. Rename local return_val variable to error. * infrun.c (keep_going): Instead of checking return value from insert_breakpoints, catch exception.
2007-11-29 Stop infrun from tracking breakpoint insertion status.Vladimir Prus1-0/+2
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. (insert_step_resume_breakpoint_at_sal): Don't insert breakpoints
2007-11-20 Remove unused breakpoint fields.Vladimir Prus1-8/+0
* breakpoint.h (struct breakpoint): Remove from_tty and flag fields. * breakpoint.c (break_command_1): Don't set from_tty and flag field set of breakpoint. (create_ada_exception_breakpoint): Don't set the from_tty field.
