3173         obstack alignment.

3183         field of frchainS.  Don't create new frags on section switch, and

3185         section, set frchain_now to absolute_frchain.  Verify that
3186         frch_last and frag_now match on entry and exit.  Initialize

3198         allocation.

3218
3219         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
3220         frag_now_fix instead of accessing obstack info directly.
