4447         obstack alignment.
4448         * frags.h (frags): Declaration deleted.

4456         (subseg_set_rest): Save and restore frag_now in frch_frag_now
4457         field of frchainS.  Don't create new frags on section switch, and

4459         section, set frchain_now to absolute_frchain.  Verify that
4460         frch_last and frag_now match on entry and exit.  Initialize

4472         allocation.

4492
4493         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
4494         frag_now_fix instead of accessing obstack info directly.

4497
