   2
   3         * input-scrub.c (as_where): Set name to null pointer if we don't
   4         have a file name.
   5         * messages.c (identify): Only print filename if non-null.
   6         (as_show_where): Ditto, for line number too.
   7         (as_warn_internal, as_bad_internal): Ditto.
   8
   9         * input-file.c (input_file_open): If the input file can't be
  10         opened, consider it an error.
  11
  12 Mon Oct 23 11:15:44 1995  James G. Smith  <jsmith@pasanda.cygnus.co.uk>
  13
  14         * config/tc-mips.c: Added mips_4100 control, and support for
  15         accepting the 4100 as a MIPS architecture variant (md_begin,
  16         macro_build, mips_ip, md_parse_option). Adding suitable
  17         command-line OPTIONs, and updating the help text (md_show_usage).
  18
  19 Wed Oct 18 13:20:32 1995  Ken Raeburn  <raeburn@cygnus.com>
  20
  21         * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
  22         BFD_ASSEMBLER is defined.
  23
  24         * Use one active frag and one obstack per frag chain:
  25         * frags.c (frags): Variable deleted.
  26         (frag_alloc): New function.
  27         (frag_grow, frag_more, frag_variant, frag_now_fix,
  28         frag_append_1_char): Refer to frchain_now->frch_obstack instead of
  29         frags variable.
  30         (frag_new): Ditto.  Verify that frch_last and frag_now match on
  31         entry and exit, and that old frag_now has non-zero type.  Replace
  32         "know" uses with "assert".  Use frag_alloc instead of mucking with
  33         obstack alignment.
  34         * frags.h (frags): Declaration deleted.
  35         * subsegs.h (struct frchain): Add new field frch_frag_now.
  36         * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
  37         variables.
  38         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
  39         give it any stricter alignment than frchainS structures need.  Do
  40         not initialize frags obstack.  Set frag_now to point to
  41         dummy_obstack.  Initialize absolute_frchain.
  42         (subseg_set_rest): Save and restore frag_now in frch_frag_now
  43         field of frchainS.  Don't create new frags on section switch, and
  44         use frag_alloc when creating a new frag chain.  For absolute
  45         section, set frchain_now to absolute_frchain.  Verify that
  46         frch_last and frag_now match on entry and exit.  Initialize
  47         per-chain obstack, and under gcc, set required alignment to that
  48         needed by fragS structure.
  49
  50         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
  51
  52         * stabs.c (get_stab_string_offset): Only copy input string if a
  53         fresh copy is needed, not if the section already exists.
  54         (s_stab_generic): Cache stab section name to bypass lookups, since
  55         usually it will match.  Could be made faster still by changing the
  56         memory allocation rules.
  57         (s_xstab): Cache section name to bypass repeated string
  58         allocation.
  59
  60         * frags.c (frag_new): Deleted register declarations.
  61
  62         * listing.c (frag_now): Don't declare.
  63
  64         * as.c (chunksize): New variable.
  65         (debug_memory): New variable.
  66         (main): If debug_memory is set, reduce chunksize and
  67         _bfd_chunksize.
  68         * as.h (chunksize): Declare it.
  69         * read.c (read_begin): Use it.
  70
  71         * config/tc-alpha.c (md_shortopts): Include 'g'.
  72         (md_parse_option): Ignore it.
  73
  74         * Makefile.in (distclean): Remove Makefile and config.status from
  75         testsuite directory.
  76         (clean-here): Don't delete testsuite.  Instead, delete only the
  77         files within it that would be generated by running tests.
  78
  79         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
  80         frag_now_fix instead of accessing obstack info directly.
  81         * config/tc-arm.c (s_ltorg): Ditto.
  82         (md_assemble): Ditto.
  83
  84         * config/tc-i386.c (md_assemble): Call frag_grow instead of
  85         obstack_room.
  86
  87 Wed Oct 18 12:22:59 1995  Ken Raeburn  <raeburn@cygnus.com>
  88
  89         * stabs.c (aout_process_stab): Insert debug symbol into symbol
  90         chain after parsing value expression, if any, to avoid separating
  91         continued .stabs lines.
  92
  93 Mon Oct 16 10:56:41 1995  Ian Lance Taylor  <ian@cygnus.com>
  94
  95         * config/tc-mips.c (mips_elf_pseudo_table): Remove.
  96         (mips_pop_insert): Don't call pop_insert on mips_elf_pseudo_table.
  97
  98 Mon Oct 16 07:07:37 1995  Michael Meissner  <meissner@wogglebug.tiac.net>
  99
 100         * config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for
 101         -mcom support and PPC_OPCODE_ANY for -many.
 102         (md_parse_option): Ditto.
 103         (ppc_arch): Ditto.
 104         (md_begin): For duplicate instructions, print all duplicates
 105         before aborting.

 110         common mode operation.
 111         (md_show_usage): Add -mcom to usage message.

 116         * expr.h (operatorT): Add O_symbol_rva.
 117         * read.c (cons_worker): Set O_symbol_rva when necessary.
 118         * write.c (fix_new_exp): Understand O_symbol_rva.

 130         the fix_line field.
 131         * config/obj-coff.c (coff_n_line_nos): Rename from n_line_nos, and
 132         make non-static.  Change all users.

 140
 141         * config/obj-elf.c (obj_elf_common): Convert specified byte
 142         alignment to power of two.  Set size of local bss symbol.

 164
 165         * sb.c, macro.c: Include string.h.
 166
 167         * Makefile.in (comparison): Only check *.o; we don't care if

 180
 181         * config/tc-ppc.c (parse_toc_entry): New function to parse [toc]
 182         qualifiers and detect errors if present.
