 502         entry and exit, and that old frag_now has non-zero type.  Replace
 503         "know" uses with "assert".  Use frag_alloc instead of mucking with
 504         obstack alignment.

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

 516         section, set frchain_now to absolute_frchain.  Verify that
 517         frch_last and frag_now match on entry and exit.  Initialize
 518         per-chain obstack, and under gcc, set required alignment to that
 519         needed by fragS structure.

 529         allocation.

 549
 550         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
 551         frag_now_fix instead of accessing obstack info directly.
