1468         (frag_new): Ditto.  Verify that frch_last and frag_now match on
1469         entry and exit, and that old frag_now has non-zero type.  Replace
1470         "know" uses with "assert".  Use frag_alloc instead of mucking with
1471         obstack alignment.
1472         * frags.h (frags): Declaration deleted.
1473         * subsegs.h (struct frchain): Add new field frch_frag_now.

1480         (subseg_set_rest): Save and restore frag_now in frch_frag_now
1481         field of frchainS.  Don't create new frags on section switch, and

1483         section, set frchain_now to absolute_frchain.  Verify that
1484         frch_last and frag_now match on entry and exit.  Initialize
1485         per-chain obstack, and under gcc, set required alignment to that

1492         (s_stab_generic): Cache stab section name to bypass lookups, since
1493         usually it will match.  Could be made faster still by changing the
1494         memory allocation rules.
1495         (s_xstab): Cache section name to bypass repeated string
1496         allocation.

1516
1517         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
1518         frag_now_fix instead of accessing obstack info directly.

1521
