From ab821bc6473fe7fa3982d77a837cd5913a35d6f2 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Tue, 6 Sep 2011 14:49:00 +0000 Subject: [PATCH] 2011-09-06 Pedro Alves * event-top.h (MAXPROMPTS, struct prompts): Delete. (set_async_annotation_level, set_async_prompt, pop_prompt) (push_prompt, new_async_prompt): Delete declarations. * top.h (get_prompt, set_prompt): Change prototype. (get_prefix, set_prefix, get_suffix, set_suffix): Delete declarations. * top.c (command_loop): (top_prompt): New global. (get_prefix, set_prefix, get_suffix, ): Delete. (get_prompt, set_prompt): Rewrite. (show_new_async_prompt): Rename to ... (show_prompt): ... this. (init_main): Adjust. Don't handle --annotate=2 here. * event-top.c (new_async_prompt): Delete. (the_prompts): Delete. (more_to_come): Make static. (display_gdb_prompt): Use top_level_prompt() to compute the top level prompt, and don't notify the before_prompt observers directly here. Always trick readline into not trying to display the prompt if sync_execution and displaying the primary prompt. If displaying a local/secondary prompt, always show it, even if sync_execution is set. (change_annotation_level): Delete. (top_level_prompt): New, based on change_annotation_level. (push_prompt, pop_prompt): Delete. (async_disable_stdin): No longer pushes prompt. (command_line_handler): No longer pushes or pops prompt. If more input is expected, call display_gdb_prompt with an explicit empty prompt. (async_stop_sig): Adjust.
