 143         command-line OPTIONs, and updating the help text (md_show_usage).
 144
 145 Wed Oct 18 13:20:32 1995  Ken Raeburn  <raeburn@cygnus.com>

 148         BFD_ASSEMBLER is defined.

 151         * frags.c (frags): Variable deleted.
 152         (frag_alloc): New function.
 153         (frag_grow, frag_more, frag_variant, frag_now_fix,

 156         (frag_new): Ditto.  Verify that frch_last and frag_now match on
 157         entry and exit, and that old frag_now has non-zero type.  Replace
 158         "know" uses with "assert".  Use frag_alloc instead of mucking with
 159         obstack alignment.
 160         * frags.h (frags): Declaration deleted.
 161         * subsegs.h (struct frchain): Add new field frch_frag_now.

 163         variables.
 164         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
 165         give it any stricter alignment than frchainS structures need.  Do
 166         not initialize frags obstack.  Set frag_now to point to
 167         dummy_obstack.  Initialize absolute_frchain.
 168         (subseg_set_rest): Save and restore frag_now in frch_frag_now
 169         field of frchainS.  Don't create new frags on section switch, and
 170         use frag_alloc when creating a new frag chain.  For absolute
 171         section, set frchain_now to absolute_frchain.  Verify that
 172         frch_last and frag_now match on entry and exit.  Initialize
 173         per-chain obstack, and under gcc, set required alignment to that
 174         needed by fragS structure.
 175
 176         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
 177
 178         * stabs.c (get_stab_string_offset): Only copy input string if a
 179         fresh copy is needed, not if the section already exists.
 180         (s_stab_generic): Cache stab section name to bypass lookups, since
 181         usually it will match.  Could be made faster still by changing the
 182         memory allocation rules.
 183         (s_xstab): Cache section name to bypass repeated string
 184         allocation.
 185
 186         * frags.c (frag_new): Deleted register declarations.
 187
 188         * listing.c (frag_now): Don't declare.

 193         _bfd_chunksize.
 194         * as.h (chunksize): Declare it.
 195         * read.c (read_begin): Use it.
 196
 197         * config/tc-alpha.c (md_shortopts): Include 'g'.

 201         testsuite directory.
 202         (clean-here): Don't delete testsuite.  Instead, delete only the
 203         files within it that would be generated by running tests.
 204
 205         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
 206         frag_now_fix instead of accessing obstack info directly.
 207         * config/tc-arm.c (s_ltorg): Ditto.
 208         (md_assemble): Ditto.
 209
 210         * config/tc-i386.c (md_assemble): Call frag_grow instead of

 214
 215         * stabs.c (aout_process_stab): Insert debug symbol into symbol
 216         chain after parsing value expression, if any, to avoid separating
