   2
   3         * config/tc-mips.c: Added mips_4100 control, and support for
   4         accepting the 4100 as a MIPS architecture variant (md_begin,
   5         macro_build, mips_ip, md_parse_option). Adding suitable
   6         command-line OPTIONs, and updating the help text (md_show_usage).

   8 Wed Oct 18 13:20:32 1995  Ken Raeburn  <raeburn@cygnus.com>
   9
  10         * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
  11         BFD_ASSEMBLER is defined.
  12
  13         * Use one active frag and one obstack per frag chain:
  14         * frags.c (frags): Variable deleted.
  15         (frag_alloc): New function.
  16         (frag_grow, frag_more, frag_variant, frag_now_fix,
  17         frag_append_1_char): Refer to frchain_now->frch_obstack instead of
  18         frags variable.
  19         (frag_new): Ditto.  Verify that frch_last and frag_now match on
  20         entry and exit, and that old frag_now has non-zero type.  Replace
  21         "know" uses with "assert".  Use frag_alloc instead of mucking with
  22         obstack alignment.
  23         * frags.h (frags): Declaration deleted.
  24         * subsegs.h (struct frchain): Add new field frch_frag_now.
  25         * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
  26         variables.
  27         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
  28         give it any stricter alignment than frchainS structures need.  Do
  29         not initialize frags obstack.  Set frag_now to point to
  30         dummy_obstack.  Initialize absolute_frchain.
  31         (subseg_set_rest): Save and restore frag_now in frch_frag_now
  32         field of frchainS.  Don't create new frags on section switch, and
  33         use frag_alloc when creating a new frag chain.  For absolute
  34         section, set frchain_now to absolute_frchain.  Verify that
  35         frch_last and frag_now match on entry and exit.  Initialize
  36         per-chain obstack, and under gcc, set required alignment to that
  37         needed by fragS structure.
  38
  39         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
  40
  41         * stabs.c (get_stab_string_offset): Only copy input string if a
  42         fresh copy is needed, not if the section already exists.
  43         (s_stab_generic): Cache stab section name to bypass lookups, since
  44         usually it will match.  Could be made faster still by changing the
  45         memory allocation rules.
  46         (s_xstab): Cache section name to bypass repeated string
  47         allocation.
  48
  49         * frags.c (frag_new): Deleted register declarations.
  50
  51         * listing.c (frag_now): Don't declare.
  52
  53         * as.c (chunksize): New variable.
  54         (debug_memory): New variable.
  55         (main): If debug_memory is set, reduce chunksize and
  56         _bfd_chunksize.
  57         * as.h (chunksize): Declare it.
  58         * read.c (read_begin): Use it.
  59
  60         * config/tc-alpha.c (md_shortopts): Include 'g'.
  61         (md_parse_option): Ignore it.
  62
  63         * Makefile.in (distclean): Remove Makefile and config.status from
  64         testsuite directory.
  65         (clean-here): Don't delete testsuite.  Instead, delete only the
  66         files within it that would be generated by running tests.
  67
  68         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
  69         frag_now_fix instead of accessing obstack info directly.
  70         * config/tc-arm.c (s_ltorg): Ditto.
  71         (md_assemble): Ditto.
  72
  73         * config/tc-i386.c (md_assemble): Call frag_grow instead of
  74         obstack_room.
  75
  76 Wed Oct 18 12:22:59 1995  Ken Raeburn  <raeburn@cygnus.com>
  77
  78         * stabs.c (aout_process_stab): Insert debug symbol into symbol
  79         chain after parsing value expression, if any, to avoid separating
  80         continued .stabs lines.
  81
  82 Mon Oct 16 10:56:41 1995  Ian Lance Taylor  <ian@cygnus.com>
  83
  84         * config/tc-mips.c (mips_elf_pseudo_table): Remove.
  85         (mips_pop_insert): Don't call pop_insert on mips_elf_pseudo_table.
  86
  87 Mon Oct 16 07:07:37 1995  Michael Meissner  <meissner@wogglebug.tiac.net>
  88
  89         * config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for
  90         -mcom support and PPC_OPCODE_ANY for -many.
  91         (md_parse_option): Ditto.
  92         (ppc_arch): Ditto.
  93         (md_begin): For duplicate instructions, print all duplicates
  94         before aborting.
  95
  96 Sun Oct 15 22:06:14 1995  Michael Meissner  <meissner@cygnus.com>

  98         * config/tc-ppc.c (md_parse_option): Support for -mcom to turn on
  99         common mode operation.
 100         (md_show_usage): Add -mcom to usage message.
 101

 103
 104         * expr.c (op_rank): Add O_symbol_rva.
 105         * expr.h (operatorT): Add O_symbol_rva.
 106         * read.c (cons_worker): Set O_symbol_rva when necessary.
 107         * write.c (fix_new_exp): Understand O_symbol_rva.

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

 129
 130         * config/obj-elf.c (obj_elf_common): Convert specified byte
 131         alignment to power of two.  Set size of local bss symbol.

 151         despite its being commented out for now.
 152         * doc/c-ns32k.texi: New file.
 153
 154         * sb.c, macro.c: Include string.h.
 155
 156         * Makefile.in (comparison): Only check *.o; we don't care if
 157         timestamps inserted by the native linker differ.
 158
 159         * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern

 169
 170         * config/tc-ppc.c (parse_toc_entry): New function to parse [toc]
 171         qualifiers and detect errors if present.
 172         (md_assemble): Add call to parse_toc_entry. Also added some support
 173         for the [tocv] qualifier.
