   3         * Makefile.in (diststuff):  Also make info.

   5
   6 Tue Oct 24 15:21:33 1995  Jeffrey A Law  (law@cygnus.com)
   7
   8         * config/tc-hppa.c (md_pseudo_table): Add new ".nsubspa" opcode.
   9         (pa_subspace): For ".nsubspa", always create a new subspace
  10         with the given attributes, even if one already exists with the
  11         same name.
  12
  13 Tue Oct 24 14:50:38 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
  14
  15         * config/tc-ppc.h (TC_FORCE_RELOCATION_SECTION): Rename from
  16         TC_FORCE_RELOCATION, taking an additional section argument.  If
  17         the section of the target symbol is not the same as the current
  18         section, always force the relocation to be used.
  19         (MD_PCREL_FROM_SECTION): New macro to call md_pcrel_from_section.
  20
  21         * config/tc-ppc.c (md_pcrel_from_section): Rename from the
  22         md_pcrel_from function, taking an additional section argument.
  23         Invoke TC_FORCE_RELOCATION_SECTION instead of TC_FORCE_RELOCATION.
  24
  25         * write.c (TC_FORCE_RELOCATION_SECTION): Define in terms of the
  26         older TC_FORCE_RELOCATION if not defined.
  27         (MD_PCREL_FROM_SECTION): If not defined, invoke md_pcrel_from.
  28         (fixup_segment): Use MD_PCREL_FROM_SECTION instead of
  29         md_pcrel_from, and TC_FORCE_RELOCATION_SECTION instead of
  30         TC_FORCE_RELOCATION.
  31
  32 Mon Oct 23 16:20:04 1995  Ken Raeburn  <raeburn@cygnus.com>
  33
  34         * input-scrub.c (as_where): Set name to null pointer if we don't
  35         have a file name.
  36         * messages.c (identify): Only print filename if non-null.
  37         (as_show_where): Ditto, for line number too.
  38         (as_warn_internal, as_bad_internal): Ditto.
  39
  40         * input-file.c (input_file_open): If the input file can't be
  41         opened, consider it an error.
  42
  43 Mon Oct 23 11:15:44 1995  James G. Smith  <jsmith@pasanda.cygnus.co.uk>
  44
  45         * config/tc-mips.c: Added mips_4100 control, and support for
  46         accepting the 4100 as a MIPS architecture variant (md_begin,
  47         macro_build, mips_ip, md_parse_option). Adding suitable
  48         command-line OPTIONs, and updating the help text (md_show_usage).
  49
  50 Wed Oct 18 13:20:32 1995  Ken Raeburn  <raeburn@cygnus.com>
  51
  52         * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
  53         BFD_ASSEMBLER is defined.
  54
  55         * Use one active frag and one obstack per frag chain:
  56         * frags.c (frags): Variable deleted.
  57         (frag_alloc): New function.
  58         (frag_grow, frag_more, frag_variant, frag_now_fix,
  59         frag_append_1_char): Refer to frchain_now->frch_obstack instead of
  60         frags variable.
  61         (frag_new): Ditto.  Verify that frch_last and frag_now match on
  62         entry and exit, and that old frag_now has non-zero type.  Replace
  63         "know" uses with "assert".  Use frag_alloc instead of mucking with
  64         obstack alignment.
  65         * frags.h (frags): Declaration deleted.
  66         * subsegs.h (struct frchain): Add new field frch_frag_now.
  67         * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
  68         variables.
  69         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
  70         give it any stricter alignment than frchainS structures need.  Do
  71         not initialize frags obstack.  Set frag_now to point to
  72         dummy_obstack.  Initialize absolute_frchain.
  73         (subseg_set_rest): Save and restore frag_now in frch_frag_now
  74         field of frchainS.  Don't create new frags on section switch, and
  75         use frag_alloc when creating a new frag chain.  For absolute
  76         section, set frchain_now to absolute_frchain.  Verify that
  77         frch_last and frag_now match on entry and exit.  Initialize
  78         per-chain obstack, and under gcc, set required alignment to that
  79         needed by fragS structure.
  80
  81         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
  82
  83         * stabs.c (get_stab_string_offset): Only copy input string if a
  84         fresh copy is needed, not if the section already exists.
  85         (s_stab_generic): Cache stab section name to bypass lookups, since
  86         usually it will match.  Could be made faster still by changing the
  87         memory allocation rules.
  88         (s_xstab): Cache section name to bypass repeated string
  89         allocation.
  90
  91         * frags.c (frag_new): Deleted register declarations.
  92
  93         * listing.c (frag_now): Don't declare.
  94
  95         * as.c (chunksize): New variable.
  96         (debug_memory): New variable.
  97         (main): If debug_memory is set, reduce chunksize and
  98         _bfd_chunksize.
  99         * as.h (chunksize): Declare it.
 100         * read.c (read_begin): Use it.
 101
 102         * config/tc-alpha.c (md_shortopts): Include 'g'.
 103         (md_parse_option): Ignore it.
 104
 105         * Makefile.in (distclean): Remove Makefile and config.status from
 106         testsuite directory.
 107         (clean-here): Don't delete testsuite.  Instead, delete only the
 108         files within it that would be generated by running tests.
 109
 110         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
 111         frag_now_fix instead of accessing obstack info directly.
 112         * config/tc-arm.c (s_ltorg): Ditto.
 113         (md_assemble): Ditto.
 114
 115         * config/tc-i386.c (md_assemble): Call frag_grow instead of
 116         obstack_room.
 117
 118 Wed Oct 18 12:22:59 1995  Ken Raeburn  <raeburn@cygnus.com>
 119
 120         * stabs.c (aout_process_stab): Insert debug symbol into symbol
 121         chain after parsing value expression, if any, to avoid separating
 122         continued .stabs lines.
 123
 124 Mon Oct 16 10:56:41 1995  Ian Lance Taylor  <ian@cygnus.com>
 125
 126         * config/tc-mips.c (mips_elf_pseudo_table): Remove.
 127         (mips_pop_insert): Don't call pop_insert on mips_elf_pseudo_table.
 128
 129 Mon Oct 16 07:07:37 1995  Michael Meissner  <meissner@wogglebug.tiac.net>
 130
 131         * config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for
 132         -mcom support and PPC_OPCODE_ANY for -many.
 133         (md_parse_option): Ditto.
 134         (ppc_arch): Ditto.
 135         (md_begin): For duplicate instructions, print all duplicates
 136         before aborting.
