   2
   3         * config/tc-ppc.h (TC_FORCE_RELOCATION_SECTION): Rename from
   4         TC_FORCE_RELOCATION, taking an additional section argument.  If
   5         the section of the target symbol is not the same as the current
   6         section, always force the relocation to be used.
   7         (MD_PCREL_FROM_SECTION): New macro to call md_pcrel_from_section.
   8
   9         * config/tc-ppc.c (md_pcrel_from_section): Rename from the
  10         md_pcrel_from function, taking an additional section argument.
  11         Invoke TC_FORCE_RELOCATION_SECTION instead of TC_FORCE_RELOCATION.
  12
  13         * write.c (TC_FORCE_RELOCATION_SECTION): Define in terms of the
  14         older TC_FORCE_RELOCATION if not defined.
  15         (MD_PCREL_FROM_SECTION): If not defined, invoke md_pcrel_from.
  16         (fixup_segment): Use MD_PCREL_FROM_SECTION instead of
  17         md_pcrel_from, and TC_FORCE_RELOCATION_SECTION instead of
  18         TC_FORCE_RELOCATION.

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