X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=22bcceeec6bfd4373fa8d09acff66115800f0455;p=deliverable%2Fbinutils-gdb.git

convert to_get_tib_address

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

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