Subject: 	* target.c (add_target):  Don't call clean_target on target
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a3ecbe7c52aebaf22ee74dde39964487d606bdb0;p=binutils-gdb.git

	* target.c (add_target):  Don't call clean_target on target
	vectors anymore.
	* (unpush_target):  Test for to_close being set before calling.
	* (target_xfer_memory, target_info):  Check for to_has_memory
	before playing with memory.
