- Subject: [PATCH] record: make record goto begin/end sub-commands
The "record goto" command scans its arguments for "begin", "start", or "end".
Turn those into sub-commands.
Document the "record goto" command.
CC: Eli Zaretskii <eliz@gnu.org>
2013-05-06 Markus Metzger <markus.t.metzger@intel.com>
* record.c (record_goto_cmdlist): New.
(cmd_record_goto): Split into this ...
(cmd_record_goto_begin): ... this
(cmd_record_goto_end): ... and this.
(_initialize_record): Change "record goto" to prefix command.
Add commands for "record goto begin" and "record goto end".
Add an alias for "record goto start" to "record goto begin".
doc/
* gdb.texinfo (Process Record and Replay): Document the
"record goto" command and its sub-commands.
