5118         obstack alignment.

5127         (subseg_set_rest): Save and restore frag_now in frch_frag_now
5128         field of frchainS.  Don't create new frags on section switch, and

5130         section, set frchain_now to absolute_frchain.  Verify that
5131         frch_last and frag_now match on entry and exit.  Initialize

5143         allocation.

5163
5164         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
5165         frag_now_fix instead of accessing obstack info directly.
