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

 232         (subseg_set_rest): Save and restore frag_now in frch_frag_now
 233         field of frchainS.  Don't create new frags on section switch, and
 234         use frag_alloc when creating a new frag chain.  For absolute
 235         section, set frchain_now to absolute_frchain.  Verify that
 236         frch_last and frag_now match on entry and exit.  Initialize
 237         per-chain obstack, and under gcc, set required alignment to that
 238         needed by fragS structure.

 241
 242         * stabs.c (get_stab_string_offset): Only copy input string if a
 243         fresh copy is needed, not if the section already exists.
 244         (s_stab_generic): Cache stab section name to bypass lookups, since
 245         usually it will match.  Could be made faster still by changing the
 246         memory allocation rules.

 248         allocation.

 268
 269         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
 270         frag_now_fix instead of accessing obstack info directly.
 271         * config/tc-arm.c (s_ltorg): Ditto.
