1618
1619         * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when

1625         (frag_grow, frag_more, frag_variant, frag_now_fix,

1627         frags variable.
1628         (frag_new): Ditto.  Verify that frch_last and frag_now match on
1629         entry and exit, and that old frag_now has non-zero type.  Replace
1630         "know" uses with "assert".  Use frag_alloc instead of mucking with
1631         obstack alignment.
1632         * frags.h (frags): Declaration deleted.
1633         * subsegs.h (struct frchain): Add new field frch_frag_now.

1638         not initialize frags obstack.  Set frag_now to point to
1639         dummy_obstack.  Initialize absolute_frchain.
1640         (subseg_set_rest): Save and restore frag_now in frch_frag_now
1641         field of frchainS.  Don't create new frags on section switch, and
1642         use frag_alloc when creating a new frag chain.  For absolute
1643         section, set frchain_now to absolute_frchain.  Verify that
1644         frch_last and frag_now match on entry and exit.  Initialize
1645         per-chain obstack, and under gcc, set required alignment to that
1646         needed by fragS structure.
1647
1648         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
1649
1650         * stabs.c (get_stab_string_offset): Only copy input string if a
1651         fresh copy is needed, not if the section already exists.
1652         (s_stab_generic): Cache stab section name to bypass lookups, since
1653         usually it will match.  Could be made faster still by changing the
1654         memory allocation rules.
