[PATCH 1/2] Use std::map for MI commands in mi-cmds.c
- From: didier dot nadeau at gmail dot com

- Subject: [PATCH 1/2] Use std::map for MI commands in mi-cmds.c
- Authentication-results: sourceware.org; auth=none
- References: <1486100763-16933-1-git-send-email-didier.nadeau@gmail.com>
From: Didier Nadeau <didier.nadeau@gmail.com>
This changes the hashmap used in mi-cmds.c from a custom
structure to std::map. This is done to be able to add new
MI commands at runtime, the previous structure had a fixed
size array.
gdb/ChangeLog:
2017-02-02 Didier Nadeau <didier.nadeau@gmail.com>
* mi/mi-cmds.h (mi_cmd_up): New typedef.
(mi_lookup): Rename to ...
(mi_cmd_lookup): this.
* mi/mi-cmds.c (_initialize_mi_cmds): Remove declaration.
(lookup_table): Remove declaration.
(build_table): Remove declaration.
(mi_table): Rename to ...
(mi_cmd_table): this and change to std::map.
(insert_mi_cmd_entry): New function.
(DEF_MI_CMD_CLI_1, DEF_MI_CMD_CLI, DEF_MI_CMD_MI,
DEF_MI_CMD_MI_1): Remove macros.
(mi_cmds): Remove array.
(mi_lookup): Rename to ...
(mi_cmd_lookup): this.
(create_mi_cmd): New function.
(struct mi_cmd_stats): Remove.
(stats): Remove.
(add_mi_cmd_cli, add_mi_cmd_mi): New functions.
(lookup_table): Remove.
(build_table): Remove parameter.
* mi/mi-parse.c (mi_parse): Change call from mi_lookup to
mi_cmd_lookup.
* mi/mi-cmd-info.c (mi_cmd_info_gdb_mi_command): Change call
from mi_lookup to mi_cmd_lookup.
