  21
  22         * config/tc-hppa.c (md_pseudo_table): Add new ".nsubspa" opcode.
  23         (pa_subspace): For ".nsubspa", always create a new subspace
  24         with the given attributes, even if one already exists with the
  25         same name.
  26
  27 Tue Oct 24 14:50:38 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
  28
  29         * config/tc-ppc.h (TC_FORCE_RELOCATION_SECTION): Rename from
  30         TC_FORCE_RELOCATION, taking an additional section argument.  If
  31         the section of the target symbol is not the same as the current
  32         section, always force the relocation to be used.
  33         (MD_PCREL_FROM_SECTION): New macro to call md_pcrel_from_section.
  34
  35         * config/tc-ppc.c (md_pcrel_from_section): Rename from the
  36         md_pcrel_from function, taking an additional section argument.
  37         Invoke TC_FORCE_RELOCATION_SECTION instead of TC_FORCE_RELOCATION.

  40         older TC_FORCE_RELOCATION if not defined.
  41         (MD_PCREL_FROM_SECTION): If not defined, invoke md_pcrel_from.
  42         (fixup_segment): Use MD_PCREL_FROM_SECTION instead of
  43         md_pcrel_from, and TC_FORCE_RELOCATION_SECTION instead of
  44         TC_FORCE_RELOCATION.
  45
  46 Mon Oct 23 16:20:04 1995  Ken Raeburn  <raeburn@cygnus.com>
  47
  48         * input-scrub.c (as_where): Set name to null pointer if we don't

  50         * messages.c (identify): Only print filename if non-null.
  51         (as_show_where): Ditto, for line number too.
  52         (as_warn_internal, as_bad_internal): Ditto.
  53
  54         * input-file.c (input_file_open): If the input file can't be
  55         opened, consider it an error.
  56
  57 Mon Oct 23 11:15:44 1995  James G. Smith  <jsmith@pasanda.cygnus.co.uk>
  58
  59         * config/tc-mips.c: Added mips_4100 control, and support for
  60         accepting the 4100 as a MIPS architecture variant (md_begin,
  61         macro_build, mips_ip, md_parse_option). Adding suitable
  62         command-line OPTIONs, and updating the help text (md_show_usage).
  63
  64 Wed Oct 18 13:20:32 1995  Ken Raeburn  <raeburn@cygnus.com>
  65
  66         * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
  67         BFD_ASSEMBLER is defined.
  68
  69         * Use one active frag and one obstack per frag chain:
  70         * frags.c (frags): Variable deleted.
  71         (frag_alloc): New function.
  72         (frag_grow, frag_more, frag_variant, frag_now_fix,
  73         frag_append_1_char): Refer to frchain_now->frch_obstack instead of
  74         frags variable.
  75         (frag_new): Ditto.  Verify that frch_last and frag_now match on
  76         entry and exit, and that old frag_now has non-zero type.  Replace
  77         "know" uses with "assert".  Use frag_alloc instead of mucking with
  78         obstack alignment.
  79         * frags.h (frags): Declaration deleted.
  80         * subsegs.h (struct frchain): Add new field frch_frag_now.
  81         * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
  82         variables.
  83         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
  84         give it any stricter alignment than frchainS structures need.  Do
  85         not initialize frags obstack.  Set frag_now to point to
  86         dummy_obstack.  Initialize absolute_frchain.
  87         (subseg_set_rest): Save and restore frag_now in frch_frag_now
  88         field of frchainS.  Don't create new frags on section switch, and
  89         use frag_alloc when creating a new frag chain.  For absolute
  90         section, set frchain_now to absolute_frchain.  Verify that
  91         frch_last and frag_now match on entry and exit.  Initialize
  92         per-chain obstack, and under gcc, set required alignment to that
  93         needed by fragS structure.
  94
  95         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
  96
  97         * stabs.c (get_stab_string_offset): Only copy input string if a
  98         fresh copy is needed, not if the section already exists.
  99         (s_stab_generic): Cache stab section name to bypass lookups, since
 100         usually it will match.  Could be made faster still by changing the
 101         memory allocation rules.
 102         (s_xstab): Cache section name to bypass repeated string
 103         allocation.
 104
 105         * frags.c (frag_new): Deleted register declarations.
 106
 107         * listing.c (frag_now): Don't declare.
 108
 109         * as.c (chunksize): New variable.
 110         (debug_memory): New variable.
 111         (main): If debug_memory is set, reduce chunksize and
 112         _bfd_chunksize.
 113         * as.h (chunksize): Declare it.
 114         * read.c (read_begin): Use it.
 115
 116         * config/tc-alpha.c (md_shortopts): Include 'g'.
 117         (md_parse_option): Ignore it.
 118
 119         * Makefile.in (distclean): Remove Makefile and config.status from
 120         testsuite directory.
 121         (clean-here): Don't delete testsuite.  Instead, delete only the
 122         files within it that would be generated by running tests.
 123
 124         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
 125         frag_now_fix instead of accessing obstack info directly.
 126         * config/tc-arm.c (s_ltorg): Ditto.
 127         (md_assemble): Ditto.
 128
 129         * config/tc-i386.c (md_assemble): Call frag_grow instead of
 130         obstack_room.
 131
 132 Wed Oct 18 12:22:59 1995  Ken Raeburn  <raeburn@cygnus.com>
 133
 134         * stabs.c (aout_process_stab): Insert debug symbol into symbol
 135         chain after parsing value expression, if any, to avoid separating
 136         continued .stabs lines.
 137
 138 Mon Oct 16 10:56:41 1995  Ian Lance Taylor  <ian@cygnus.com>

 144
 145         * config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for
 146         -mcom support and PPC_OPCODE_ANY for -many.
 147         (md_parse_option): Ditto.
 148         (ppc_arch): Ditto.
 149         (md_begin): For duplicate instructions, print all duplicates
 150         before aborting.
