Subject: [PATCH v9 12/29] record-btrace: make ranges include begin and end
Date: Thu, 19 Dec 2013 16:45:00 -0000	[thread overview]
Message-ID: <1387471499-29444-13-git-send-email-markus.t.metzger@intel.com> (raw)
In-Reply-To: <1387471499-29444-1-git-send-email-markus.t.metzger@intel.com>

The "record function-call-history" and "record instruction-history" commands
accept a range "begin, end".  End is not included in both cases.  Include it.

CC: Eli Zaretskii  <eliz@gnu.org>

2013-12-19  Markus Metzger  <markus.t.metzger@intel.com>

	* record-btrace.c (record_btrace_insn_history_range): Include
	end.
	(record_btrace_insn_history_from): Adjust range.
	(record_btrace_call_history_range): Include
	end.
	(record_btrace_call_history_from): Adjust range.

testsuite/
	* gdb.btrace/function_call_history.exp: Update tests.
	* gdb.btrace/instruction_history.exp: Update tests.

doc/
	* gdb.texinfo (Process Record and Replay): Update documentation.
