Browse Source 
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.
