gdb/ * breakpoint.h (print_recreate_thread): Declare. (struct breakpoint): Move step_count, pass_count, number_on_target, static_trace_marker_id, static_trace_marker_id_idx ... (struct tracepoint): ... to this new struct. (get_tracepoint, get_tracepoint_by_number_on_target) (get_tracepoint_by_number): Change return type to struct tracepoint pointer. * breakpoint.c (is_tracepoint_type): New, factored out from is_tracepoint. (is_tracepoint): Adjust. (print_one_breakpoint_location): Cast to struct tracepoint as necessary, and adjust. (print_recreate_catch_fork, print_recreate_catch_vfork) (print_recreate_catch_syscall, print_recreate_catch_exec): Call print_recreate_thread. (init_breakpoint_sal): New, factored out from create_breakpoint_sal. (create_breakpoint_sal): Reimplement. (create_breakpoint): Allocate a struct tracecepoint if the caller wanted a tracepoint. Use init_breakpoint_sal and install_breakpoint. (print_recreate_ranged_breakpoint, print_recreate_watchpoint) (print_recreate_masked_watchpoint) (print_recreate_exception_catchpoint): Call print_recreate_thread. (tracepoint_print_one_detail): Adjust. (tracepoint_print_recreate): Adjust. Call print_recreate_thread. Dump the pass count here. (update_static_tracepoint): Adjust. (addr_string_to_sals): Adjust. (create_tracepoint_from_upload): Adjust. Change return type to struct tracepoint pointer. (trace_pass_set_count): Change parameter type to struct tracepoint pointer, and adjust. (trace_pass_command): Adjust. (get_tracepoint, get_tracepoint_by_number_on_target) (get_tracepoint_by_number): Change return type to struct tracepoint pointer, and adjust. (print_recreate_thread): New, factored out from save_breakpoints. (save_breakpoints): Don't print thread and task and passcount recreation here. * remote.c (remote_download_tracepoint): Adjust. * tracepoint.c (trace_actions_command, validate_actionline) (start_tracing, tfind_1, trace_find_tracepoint_command) (trace_dump_command): Adjust. (find_matching_tracepoint): Change return type to struct tracepoint pointer, and adjust. (merge_uploaded_tracepoints, tfile_get_traceframe_address) (tfile_trace_find, tfile_fetch_registers): Adjust. * tracepoint.h (create_tracepoint_from_upload): Change return type to struct tracepoint pointer. * ada-lang.c (print_recreate_exception): Call print_recreate_thread. * mi/mi-cmd-break.c (mi_cmd_break_passcount): Adjust.
