1140         (frag_new): Ditto.  Verify that frch_last and frag_now match on
1141         entry and exit, and that old frag_now has non-zero type.  Replace
1142         "know" uses with "assert".  Use frag_alloc instead of mucking with
1143         obstack alignment.
1144         * frags.h (frags): Declaration deleted.
1145         * subsegs.h (struct frchain): Add new field frch_frag_now.

1152         (subseg_set_rest): Save and restore frag_now in frch_frag_now
1153         field of frchainS.  Don't create new frags on section switch, and

1155         section, set frchain_now to absolute_frchain.  Verify that
1156         frch_last and frag_now match on entry and exit.  Initialize
1157         per-chain obstack, and under gcc, set required alignment to that

1161
1162         * stabs.c (get_stab_string_offset): Only copy input string if a

1164         (s_stab_generic): Cache stab section name to bypass lookups, since
1165         usually it will match.  Could be made faster still by changing the
1166         memory allocation rules.
1167         (s_xstab): Cache section name to bypass repeated string
1168         allocation.

1188
1189         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
1190         frag_now_fix instead of accessing obstack info directly.

1192         (md_assemble): Ditto.
1193
