 175         * frags.c (frags): Variable deleted.
 176         (frag_alloc): New function.
 177         (frag_grow, frag_more, frag_variant, frag_now_fix,

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

 188         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
 189         give it any stricter alignment than frchainS structures need.  Do
 190         not initialize frags obstack.  Set frag_now to point to
 191         dummy_obstack.  Initialize absolute_frchain.
 192         (subseg_set_rest): Save and restore frag_now in frch_frag_now
 193         field of frchainS.  Don't create new frags on section switch, and
 194         use frag_alloc when creating a new frag chain.  For absolute
 195         section, set frchain_now to absolute_frchain.  Verify that
 196         frch_last and frag_now match on entry and exit.  Initialize
 197         per-chain obstack, and under gcc, set required alignment to that
 198         needed by fragS structure.

 200         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
 201
 202         * stabs.c (get_stab_string_offset): Only copy input string if a
 203         fresh copy is needed, not if the section already exists.
 204         (s_stab_generic): Cache stab section name to bypass lookups, since
 205         usually it will match.  Could be made faster still by changing the
 206         memory allocation rules.
 207         (s_xstab): Cache section name to bypass repeated string
 208         allocation.

 225         testsuite directory.

 228
 229         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
 230         frag_now_fix instead of accessing obstack info directly.
 231         * config/tc-arm.c (s_ltorg): Ditto.
 232         (md_assemble): Ditto.
 233

 238
 239         * stabs.c (aout_process_stab): Insert debug symbol into symbol
