Subject: convert to_can_accel_watchpoint_condition
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=77cdffe90e96b731eae441f08a69eaa231d65a7b;p=binutils-gdb.git

convert to_can_accel_watchpoint_condition

2014-02-19  Tom Tromey  <tromey@redhat.com>

	* target-delegates.c: Rebuild.
	* target.c (update_current_target): Don't inherit or default
	to_can_accel_watchpoint_condition.
	* target.h (struct target_ops)
	<to_can_accel_watchpoint_condition>: Use TARGET_DEFAULT_RETURN.
