 468         * frags.c (frags): Variable deleted.
 469         (frag_alloc): New function.
 470         (frag_grow, frag_more, frag_variant, frag_now_fix,

 473         (frag_new): Ditto.  Verify that frch_last and frag_now match on
 474         entry and exit, and that old frag_now has non-zero type.  Replace
 475         "know" uses with "assert".  Use frag_alloc instead of mucking with
 476         obstack alignment.
 477         * frags.h (frags): Declaration deleted.

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

 488         section, set frchain_now to absolute_frchain.  Verify that
 489         frch_last and frag_now match on entry and exit.  Initialize
 490         per-chain obstack, and under gcc, set required alignment to that
 491         needed by fragS structure.

 497         (s_stab_generic): Cache stab section name to bypass lookups, since

 501         allocation.

 521
 522         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
 523         frag_now_fix instead of accessing obstack info directly.

 525         (md_assemble): Ditto.
 526

 531
 532         * stabs.c (aout_process_stab): Insert debug symbol into symbol
