 142         BFD_ASSEMBLER is defined.

 145         * frags.c (frags): Variable deleted.
 146         (frag_alloc): New function.
 147         (frag_grow, frag_more, frag_variant, frag_now_fix,

 150         (frag_new): Ditto.  Verify that frch_last and frag_now match on
 151         entry and exit, and that old frag_now has non-zero type.  Replace
 152         "know" uses with "assert".  Use frag_alloc instead of mucking with
 153         obstack alignment.
 154         * frags.h (frags): Declaration deleted.
 155         * subsegs.h (struct frchain): Add new field frch_frag_now.

 158         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
 159         give it any stricter alignment than frchainS structures need.  Do
 160         not initialize frags obstack.  Set frag_now to point to
 161         dummy_obstack.  Initialize absolute_frchain.
 162         (subseg_set_rest): Save and restore frag_now in frch_frag_now
 163         field of frchainS.  Don't create new frags on section switch, and
 164         use frag_alloc when creating a new frag chain.  For absolute
 165         section, set frchain_now to absolute_frchain.  Verify that
 166         frch_last and frag_now match on entry and exit.  Initialize
 167         per-chain obstack, and under gcc, set required alignment to that
 168         needed by fragS structure.
 169
 170         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
 171
 172         * stabs.c (get_stab_string_offset): Only copy input string if a
 173         fresh copy is needed, not if the section already exists.
 174         (s_stab_generic): Cache stab section name to bypass lookups, since
 175         usually it will match.  Could be made faster still by changing the
 176         memory allocation rules.
 177         (s_xstab): Cache section name to bypass repeated string
 178         allocation.
 179

 182         * listing.c (frag_now): Don't declare.

 189         * read.c (read_begin): Use it.

 195         testsuite directory.
 196         (clean-here): Don't delete testsuite.  Instead, delete only the
 197         files within it that would be generated by running tests.
 198
 199         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
 200         frag_now_fix instead of accessing obstack info directly.
 201         * config/tc-arm.c (s_ltorg): Ditto.
 202         (md_assemble): Ditto.
 203
 204         * config/tc-i386.c (md_assemble): Call frag_grow instead of
 205         obstack_room.

 208
 209         * stabs.c (aout_process_stab): Insert debug symbol into symbol
