X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=43eba180841a33f29ccc7130e9892ecf852e7c87;p=platform%2Fupstream%2Fbinutils.git

convert to_thread_architecture

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

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