X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d9db5b2141d86dafe7b437f521ee98beffac381d;p=binutils-gdb.git

convert to_use_agent

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

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