  89         accepting the 4100 as a MIPS architecture variant (md_begin,
  90         macro_build, mips_ip, md_parse_option). Adding suitable
  91         command-line OPTIONs, and updating the help text (md_show_usage).
  92
  93 Wed Oct 18 13:20:32 1995  Ken Raeburn  <raeburn@cygnus.com>
  94
  95         * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
  96         BFD_ASSEMBLER is defined.
  97
  98         * Use one active frag and one obstack per frag chain:
  99         * frags.c (frags): Variable deleted.
 100         (frag_alloc): New function.
 101         (frag_grow, frag_more, frag_variant, frag_now_fix,
 102         frag_append_1_char): Refer to frchain_now->frch_obstack instead of
 103         frags variable.
 104         (frag_new): Ditto.  Verify that frch_last and frag_now match on
 105         entry and exit, and that old frag_now has non-zero type.  Replace
 106         "know" uses with "assert".  Use frag_alloc instead of mucking with
 107         obstack alignment.
 108         * frags.h (frags): Declaration deleted.
 109         * subsegs.h (struct frchain): Add new field frch_frag_now.
 110         * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
 111         variables.
 112         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
 113         give it any stricter alignment than frchainS structures need.  Do
 114         not initialize frags obstack.  Set frag_now to point to
 115         dummy_obstack.  Initialize absolute_frchain.
 116         (subseg_set_rest): Save and restore frag_now in frch_frag_now
 117         field of frchainS.  Don't create new frags on section switch, and
 118         use frag_alloc when creating a new frag chain.  For absolute
 119         section, set frchain_now to absolute_frchain.  Verify that
 120         frch_last and frag_now match on entry and exit.  Initialize
 121         per-chain obstack, and under gcc, set required alignment to that
 122         needed by fragS structure.
 123
 124         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
 125
 126         * stabs.c (get_stab_string_offset): Only copy input string if a
 127         fresh copy is needed, not if the section already exists.
 128         (s_stab_generic): Cache stab section name to bypass lookups, since
 129         usually it will match.  Could be made faster still by changing the
 130         memory allocation rules.
 131         (s_xstab): Cache section name to bypass repeated string
 132         allocation.
 133
 134         * frags.c (frag_new): Deleted register declarations.
 135
 136         * listing.c (frag_now): Don't declare.

 138         * as.c (chunksize): New variable.
 139         (debug_memory): New variable.
 140         (main): If debug_memory is set, reduce chunksize and
 141         _bfd_chunksize.
 142         * as.h (chunksize): Declare it.
 143         * read.c (read_begin): Use it.
 144
 145         * config/tc-alpha.c (md_shortopts): Include 'g'.
 146         (md_parse_option): Ignore it.
 147
 148         * Makefile.in (distclean): Remove Makefile and config.status from
 149         testsuite directory.
 150         (clean-here): Don't delete testsuite.  Instead, delete only the
 151         files within it that would be generated by running tests.
 152
 153         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
 154         frag_now_fix instead of accessing obstack info directly.
 155         * config/tc-arm.c (s_ltorg): Ditto.
 156         (md_assemble): Ditto.
 157
 158         * config/tc-i386.c (md_assemble): Call frag_grow instead of
 159         obstack_room.
 160
 161 Wed Oct 18 12:22:59 1995  Ken Raeburn  <raeburn@cygnus.com>
 162
 163         * stabs.c (aout_process_stab): Insert debug symbol into symbol
 164         chain after parsing value expression, if any, to avoid separating
 165         continued .stabs lines.
 166
 167 Mon Oct 16 10:56:41 1995  Ian Lance Taylor  <ian@cygnus.com>

 173
 174         * config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for

 177         (ppc_arch): Ditto.
 178         (md_begin): For duplicate instructions, print all duplicates
 179         before aborting.
