Subject: 	* subsegs.h (segment_info_type): Use fix_tail field even if
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=1b96bdce15535044d1b2b17b0e99c4beab0bf31f;p=deliverable%2Fbinutils-gdb.git

	* subsegs.h (segment_info_type): Use fix_tail field even if
	BFD_ASSEMBLER.
	* subsegs.c (subseg_change): Initialize fix_tail field.
	(subseg_get): Likewise.
	* write.c (frags_chained): New static variable.
	(fix_new_internal): If frags_chained is set, use fix_root and
	fix_tail from seg_info (now_seg), rather than frchain_now.
	(chain_frchains_together_1): Set fix_tail field.
	(chain_frchains_together): Set frags_chained.
