   2
   3         * as.h:  Move redefine of xfree.
   4         * read.c:  Use xmalloc, not malloc.
   5         * expr.c, input-scrub.c, write.c:  Avoid "know" macros
   6         that cover more than one line, since this causes char strings
   7         with embedded newlines.
   8
   9 Wed Dec 11 18:13:07 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
  10         * configure.in: handle rename of obj-coffbfd
  11         * config/obj-coffbfd.c: lint, don't fixup relocs if H8300, use
  12         tc_reloc_mangle to prepare relocation if one available

  16
  17         * input-file.c: don't close a NULL file pointer.

  32
  33 Thu Dec  5 22:46:23 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
  34
  35         * Makefile.in: idestdir and ddestdir go away.  Added
  36           copyrights and shift gpl to v2.  Added ChangeLog if it
  37           didn't exist. docdir and mandir now keyed off datadir by
  38           default.
  39
  40 Wed Dec  4 10:28:48 1991  Steve Chamberlain  (sac at cygnus.com)
  41
  42         * config/obj-coff-bfd.c (crawl_symbol_chain): only move a
  43         symbol to the end of a file if it really is external.
  44
  45
  46 Sat Nov 30 23:03:59 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
  47
  48         * as.h: reloc.h->aout/reloc.h.
  49         * a.out.gnu.h: reloc.h->aout/reloc.h
  50

  52
  53         * config/obj-coff-bfd: made multiple sections with subsections
  54         work.
  55         * config/tc-h8300.c: made $ statement sep, and int alloc 2 bytes.
  56
  57
  58 Mon Nov 25 17:26:22 1991  Steve Chamberlain  (sac at cygnus.com)
  59
  60         * as.c: (perform_an_assembly_pass): moved declaration of i to
  61         avoid a syntax error. Now always create the three default
  62         sections when in MANY_SEGMENTS mode.
  63         * as.h: New improved way of specifying MANY_SEGMENTS
  64         * configure.in: hds object format is now coff-bfd
  65         * subsegs.h: add line numbers and section stuff to the
  66         segment_info structure. (But go back later and fix.. this is
  67         COFF specific)
  68
  69
  70 Thu Oct 24 17:25:59 1991  Steve Chamberlain  (steve at rtl.cygnus.com)
  71
  72         * config/obj-coff.c (obj_coff_dim): Allows newline to end a
  73         .dim statement.
  74
  75 Mon Oct 21 09:25:33 1991  Steve Chamberlain  (steve at rtl.cygnus.com)
  76
  77         * configure.in: added ebmon entry.
  78         * output-file.c (output_file_create, output_file_close) added
  79         stuff to use bfd.
  80         * write.c: more bfd support
  81         * config/obj-coff.c  config/obj-coff.h use bfd for swapping
  82         header info.
  83         * tc-a29k: added the reloc types we support now
  84
  85
  86 Mon Oct 14 11:44:03 1991  Roland H. Pesch  (pesch at cygnus.com)
  87
  88         * doc/Makefile (as.ms): one more sed workaround for texi2roff
  89         (as.mm, as.me): new targets
  90
  91 Fri Oct 11 18:18:37 1991  Roland H. Pesch  (pesch at cygnus.com)
  92
  93         * doc/Makefile: new targets as.info, as.ms
  94         doc/as.texinfo: minor changes for texi2roff-2

  96
  97 Fri Jan  4 12:48:22 EST 1991    Jay Fenlason (hack@ai.mit.edu)
  98
  99         * messages.c  Moved as_perror from input-scrub.c  Modified the
 100         error messages to look better.
 101
 102         * output-file.c Don't call as_fatal, just call exit()
 103
 104         expr.c Slightly improve checking for foo-foo case in
 105         clean_up_expression().  Detect foo: bar: ... foo-bar...
 106
 107 Tue Dec  4 16:29:20 EST 1990    Jay Fenlason (hack@ai.mit.edu)
 108
 109         * m68k.c  Fixed an obscure bug involving AOFF mode with a
 110         large constant displacement (Was forgetting to output the
 111         extension word.)
 112
 113         make-gas.com  Added a three line patch from Eric Youngdale that
 114         makes it possible to submit make-gas.com to a batch queue.
 115
 116 Wed Nov 21 15:07:51 EST 1990    Jay Fenlason (hack@ai.mit.edu)
 117
 118         * vms.c  (VMS_TBT_Routine_END)  Add a four line patch from
 119         Eric Youngdale.
 120
 121 Tue Nov 13 14:02:15 EST 1990    Jay Fenlason (hack@ai.mti.edu)
 122
 123         * vms-dbg.c (VMS_DBG_record())  Another one character patch from
 124         Eric Youngdale.
 125
 126 Mon Oct 29 15:49:21 EST 1990    Jay Fenlason (hack@ai.mit.edu)
 127
 128         * read.c  Replace some as_warn calls with as_bad.
 129
 130 Fri Oct 26 15:21:15 EDT 1990    Jay Fenlason (hack@ai.mit.edu)
 131
 132         * i386.c, i860.c, ns32k.c       Add const changes.
 133
 134 Mon Oct 22 14:04:26 EDT 1990    Jay Fenlason (hack@ai.mit.edu)
 135
 136         * sparc.c       Add const changes.
 137
 138         * make-gas.com  define const= for VMS, since many older versions of
 139         GCC don't work correctly with const under VMS.
 140
 141 Thu Oct 18 12:44:11 EDT 1990    Jay Fenlason (hack@ai.mit.edu)
 142
 143         * i860.c i860-opcode.h  Added patches from rgb@mcc.com
 144
 145         * read.c, symbols.c, vms.c, + new_file vms-dbg-module.c
 146         Added Eric Youngdale's <YOUNGDALE@v6550c.nrl.navy.mil> VMS debugging
 147         patches, so debugging GCC output now works.
 148
 149         * hash.c (hash_grow)  Remember to blank out the wall entry in the new
 150         hash table.  This is important on systems where malloc() returns
 151         non-zero storage. . .
 152
 153 Tue Oct 16 10:11:35 EDT 1990    Jay Fenlason (hack@ai.mit.edu)
 154
 155         * output-file.c (output_file_create)  if output filename is given as
 156         '-', write to stdout.
 157
 158         * m68k.c Finally get the PCREL code to work right.  Add relaxation of
 159         PCREL stuff  This small fix from Ken Woodland
 160         (kenny%datacube.uucp@uunet.uu.net).
 161
 162         * m68k.c  Added some const declarations to constants.  (md_relax_table,
 163         md_pseudo_table, etc. . .)
 164
 165 Thu Oct 11 11:15:10 EDT 1990    Jay Fenlason (hack@ai.mit.edu)
 166
 167         * Makefile, read.c, write.c Include the i860 port.
 168         (New files i860.c i860-opcode.h i860.h)
 169
 170         * m68k.c Fix some addressing modes, (AOFF, AINDEX, etc) to work in
 171         PC relative mode.
 172
 173         * (all over)  Raeburn's const hacking.  This reduces the data-space size by
 174         declaring many tables, etc, as 'const'.
 175
 176 Mon Oct 22 22:48:22 1990  John Gilmore  (gnu at cygint)
 177
 178         Make gas work if you turn on the know() checks.
 179
 180         * app.c:  Only pass a single space through:  the one after
 181         the opcode.  All other whitespace is removed, to match the
 182         expectations of the parser in read.c.
 183
 184         * as.h: Remove obsolete comments.  Remove JF's NDEBUG so
 185         that know() can really work if you turn it on.  Make
 186         SEG_MAXIMUM_ORDINAL == SEG_REGISTER.
 187
 188         * expr.c (operand):  Change BITS_PER_INT to 8*sizeof(int).
 189
 190         * input-scrub.c:  strlen("\0") doesn't return 1...
 191         (as_where):  Add space after line number in errors, like gcc.
 192
 193         * m68k.c (s_bss):  Fake .bss into data section 255.
 194         We can't cope with a real "BSS section" yet, but we can at
 195         least do the right thing less efficiently (with lots of
 196         zeroes).
 197
 198         * read.c:  Turn lots of as_warn()'s into as_bad()'s.
 199
 200         * read.h (SKIP_WHITESPACE):  Replace last instance of ASSERT()
 201         with know().
 202
 203         * sparc.c (s_seg):  We can't put frags into the BSS segment
 204         yet, so just fake bss seg as 255th data segment.
 205
 206         * vax.c:  Remove \'s from continued macro *parameters*.  These
 207         must have been added after the last time someone turned on
 208         know() checking...
 209
 210         * write.c (relax_segment):  Refine what we know() about the
 211         symbols referenced during relaxation.
 212
 213         * Makefile (OTHER_ALIGN):  Remove, handled in tables now.
 214         Flip options a bit.  These options really ought to go
 215         elsewhere.
 216
 217 Sun Oct 21 03:57:21 1990  John Gilmore  (gnu at cygint)
 218
 219         Sun-3 fixes.
 220
 221         * expr.c, write.c:  Missing semicolon after know().
 222
 223         * write.c (fixup_segment):  Allow pc-relative accesses to undefined
 224         external symbols.  Previously this would turn off pc-rel calc
 225         of displacement, while leaving pc-rel opcode alone, botching.
 226
 227         * m68k.c (m68k_ip):  Allow pc-relative effective addresses
 228         for source operands.  "pea" instructions are a good example
 229         where we can shorten from abs long to pc+16bit.
 230         (md_convert_frag):  Fix "JBSR" comments to refer to "JSR", the
 231         actual instruction.  Insert comments about bug in 68000 bcc
 232         and dbcc long code (that doesn't get exercised much).  Add
 233         comments about long pcrel displacements for -pic.  Remove
 234         "this code has not been tested" comment.
 235         (md_estimate_size_before_relax):  Now that fixup_segment
 236         doesn't shortcircuit pc-relative fixups for undefined symbols,
 237         only output them if -pic; else turn them absolute, which is
 238         slightly faster.  More JBSR->JSR comments.
 239         (md_parse_options):  Parse -pic.
 240
 241 Fri Oct 19 14:35:20 1990  John Gilmore  (gnu at cygint)
 242
 243         * Make sparc assembler more compatible with Sun assembler.
 244         sparc.c:  reformat pseudo-op table to match main table.
 245         (md_assemble):  Add SPECIAL_CASE_FDIV to assemble FDIV*
 246         instructions as fdiv followed by fmovs to get around chip bug.
 247         (s_common, s_seg):  Accept "bss" section name.
 248         (md_assemble):  Handle "set" instructions with absolute
 249         operands, that only take one instruction rather than two.
 250         sparc-opcode.h (fdiv*):  Mark instructions "S"pecial.
 251         subsegs.c (subseg_change):  Move tail pointer too.
 252         symbols.c (colon):  Allow new definitions to override .comm symbols,
 253         as in VMS.  Sun CC depends on this.
 254         write.c (new_fix):  Always take r_type argument, not just on sparc.
 255         Chain fixP's in order, using tail pointer, so relocation
 256         records come out in forward order like Sun as.  Remove SPARC
 257         ifdefs.
 258         write.h: Add seg_fix_tailP, data_fix_tailP, text_fix_tailP.
 259
 260         * am29k.c: Use s_align_bytes rather than a local copy.
 261
 262         * read.c (s_align):  Rather than ifdef it, make two functions,
 263         s_align_bytes and s_align_ptwo.  Individual pseudo-op tables
 264         can call whichever one they like.
 265
 266         * write.c (append):  Move from append.c to here.
 267         append.c:  Remove file.
 268
 269         * Makefile (MDSRC, mdsrc):  Easy way to edit all md.c's.
 270         Fix options.  Add option for -DDEBUG for know() and assert().
 271         Remove append.c, am29k.h.  Don't build special read-sparc.o.
 272         Remove sparc.h.  "make clean" removes am29k .o's.  Add
 273         dependencies on reloc.h.
 274
 275 Thu Oct 18 17:56:34 1990  John Gilmore  (gnu at cygint)
 276
 277         * Generalize sparc extensions to relocation info.  Gas now
 278         keeps relocation information internally in a different format
 279         than how it is stored in the resulting .o.  md_ri_to_bytes()
 280         converts to external format.  md_reloc_size says how large
 281         each relocation record is in external format.
 282         sparc.h:  Remove this file.  Rename to reloc.h.  Rename struct
 283         to reloc_info_generic.
 284         reloc.h:  Add relocation types for AMD 29000.
 285         read.c, write.c:  Always call fix_new with reloc-type argument.
 286         write.c (emit_relocations): Make md_ri_to_bytes write directly
 287         to output area rather than overwriting its argument then
 288         bcopying it.
 289         md.h:  Declare md_reloc_size and md_ri_to_bytes.
 290         i386.c, am29k.c, vax.c, ms32k.c, m68k.c, sparc.c: include reloc.h.
 291         (md_reloc_size): Specify correct value.
 292         (md_ri_to_bytes):  Convert format from internal to external.
 293
 294         write.c (write_object_file):  Call md_section_align() which
 295         rounds section sizes up if desired.
 296         sparc.c (md_section_align):  Round to 8 byte boundary.
 297         i386.c, am29k.c, vax.c, ns32k.c, m68k.c (md_section_align):  Nop.
 298
 299 Mon Oct 15 22:06:11 1990  John Gilmore  (gnu at cygint)
 300
 301         Changes in support of the AMD 29000 version of gas.
 302
 303         * am29k-opcode.h:  Add dummy entry to end so we can examine
 304         item N+1 without exceeding table.
 305
 306         * am29k.h:  New include file, derived from sparc.h.  Kludged
 307         together, still needs major work to get relocation working.
 308
 309         * am29k.c:  New file, derived from sparc.c.
 310         Put 29k-specific ASM29K pseudo-ops into table.
 311         Change comment_chars to ASM29K.
 312         Change s_seg to s_use.
 313         Change s_sparc_align to s_29k_align, default operand to 4.
 314         (define_some_regs):  Define special register names.
 315         (md_begin):  Preprocess opcode table to mash together all
 316         the variants of single opcodes.  This simplifies later handling.
 317         Call define_some_regs to preset special reg names.
 318         (parse_operand):  Add, parses out an operand from a stmt.
 319         (machine_ip):  Simplify, since 29K is simpler asm language.
 320         Handle the various keyletters in the opcode table.
 321
 322
 323         Handle include files in the assembler, with a .include
 324         pseudo-op.
 325         * as.h (input_scrub_include_file):  declare.
 326         * as.c (perform_an_assembly_pass):  Avoid buffer hacking.
 327         Start us off in text segment.
 328         * read.c (read_a_source_file):  Take a name as argument,
 329         internalize all buffer handling.  Don't start a new text
 330         subsegment on each entry.  Actually use the start and end
 331         pointers returned by input_scrub_next_buffer.
 332         (s_include):  Call input_scrub_include_file for .include.
 333         * input-scrub.c:  Fix comments.
 334         (struct input_save):  Add, for saving state at .include.
 335         (input_scrub_push, input_scrub_pop):  Add, push & pop state.
 336         (input_scrub_begin):  Initialize next_saved_file.
 337         (input_scrub_end):  Free buffer.
 338         (input_scrub_include_file):  Add, to include a file.
 339         (input_scrub_close):  Add, to close a file.
 340         (input_scrub_next_buffer):  Set buffer-start address for
 341         caller.  If we hit EOF and were included, pop to previous file.
 342         * input-file.c:  Remove old includes.  Remove old file-descriptor
 343         hacking code, that was commented out.
 344         (struct saved_file):  Add, for saving state at .include.
 345         (input_file_push, input_file_pop):  Add, push & pop state.
 346         (input_file_open):  Don't buffer all files in one place.

 353
 354
 355         * app.c:  Allow overriding of character meanings by machine
 356         dependent strings.  Avoid wiring character constants into app.c.
 357         (do_scrub_begin):  New meanings override old ones, not "OR" them.

 360         into a switch for speed.  Don't assume ';' is line terminator.
 361         Reorganize switch on characters, into a switch on their (machine-
 362         dependent) lexer table meanings.
 363
 364
 365         Encapsulate knowledge of segment types in fewer places.
 366         This allows us to add the "SEG_REGISTER" type, as well as
 367         providing flexibility for eventual COFF/ELF support.
 368         * struc-symbol.h (symbol_to_segment, symbol_to_segment_type,
 369         set_symbol_segment, set_symbol_segment_keep_ext,
 370         segment_name):  Define macros to encapsulate this info.

 374         write.c:  Use macros.
 375         * i386.c, m68k.c, ns32k.c, vax.c, write.c: Change 2nd arg type of
 376         md_estimate_size_before_relax.
 377         * expr.c, read.c:  Change 'type' arg to symbol_new.

 384         * subseg.c:  Add types to tables.
 385         * expr.c (operand):  Symbols of SEG_REGISTER type are

 388
 389
 390         Allow machine descriptions to cleanly extend the set of
 391         possible operands.
 392         * expr.c (operand):  Call md_operand before rejecting an
 393         operand as unacceptable.
 394         * md.h:  declare.
 395         * i386.c, ns32k.c, m68k.c, sparc.c, vax.c:  Define null function.
 396         * am29k.c (md_operand):  Use this for %% and & prefix operators.
 397
 398
 399         Allow machine descriptions to cleanly permit symbols to be
 400         predefined upon first usage.
 401         * symbols.c (symbol_find_or_make):  Call md_undefined_symbol
 402         before making an undefined symbol.
 403         * md.h:  declare.
 404         * i386.c, ns32k.c, m68k.c, sparc.c, vax.c:  Define null function.
 405         * am29k.c (md_undefined_symbol):  use this for the local and
 406         global register names; since there are hundreds of them, it
 407         only defines them upon their first use.
 408         * expr.c (operand):  Call symbol_find_or_make rather than
 409         roll our own undefined symbols.
 410
 411
 412         Miscellaneous changes:
 413
 414         * as.h (know):  Make this useful if DEBUG defined.
 415
 416         * write.h: Support SPARC-like relocation throughout all
 417         versions.
 418
 419         * read.c (read_a_source_file): Report the name of invalid
 420         pseudo-ops.  Don't double-report junk characters.  Close the
 421         input file, which gas never used to do.
 422         (ignore_rest_of_line):  Report junk chars in ascii if
 423         printable.
 424         (s_ignore):  Ignore entire statement; used for 'listing
 425         control' statements from ASM29K, e.g. .eject.
 426
 427         * read.c (s_lsym):  Handle register equates too.
 428
 429         * read.c:  Add most ASM29K pseudo-ops to the master table.
 430         Not all are implemented yet.
 431
 432         * cond.c:  New file, for functions implementing conditional
 433         assembly pseudo-ops: .ifdef, .ifndef, .else, .endif, .ifseq,
 434         .ifsne, .end.  So far, they are just stubbed out.
 435
 436         * read.c (pobegin):  Allow the machine dependent pseudo-op
 437         table to override the generic one.  Remove #ifdef SPARC
 438         on .word, since it can now be overridden.
 439
 440         * expr.c (operand):  Support radix-2 constants.  Kill off
 441         support for octals with digits '8' and '9'.  Initial steps
 442         toward more general support for local-labels.
 443
 444         * symbols.h (symbol_table_lookup):  Remove macro, change all
 445         occurrences (in read.c, expr.c, symbols.c) to symbol_find.
 446
 447         * read.h (is_end_of_line):  Define for external use.
 448
 449         * i386.c (alloca):  Use builtin_alloca or include or extern.
 450
 451         * Makefile:  Add ALL and all: entries.  Add asm29k entries.
 452         Add cond.c and cond.o.  Remove special handling for messages.o.
 453         Add lint entry.

 465         that the locations in question do.  A xix line patch from Michael Bloom

 469
 470         * as.c  #include <sys/types.h> if _POSIX_SOURCE defined.  This because
 471         <signal.h> uses pid_t that's defined in it.
 472
 473         * m68k.c reverse the sense of -l option, and allow :w and :l to
 474         override the default size of AOFF indexes.
 475
 476         Also, allow -l to shorten branches to unknown labels from LONG to WORD.

 487 Tue Sep  4 11:40:21 EDT 1990    Jay Fenlason
 488
 489         * read.c (pseudo_set) Compain if we're setting the symbol to the
 490         difference of two symbols which are in different frags.  (We can't
 491         find out how far apart they are.)
 492
 493 Wed Aug 15 12:18:58 EDT 1990    Jay Fenlason
 494
 495         * m68k.c (m68k_ip_op)  Dyke out the code that deals with parsing
 496         :[wl] at the end of expressions since it is handled in get_num()
 497         and this was putting the result in the wrong place anyway.
 498         Corrected a couple of other references to ->isiz instead of con?->e_siz

 707                 with references to the -h option.  These small VMS patches
 708                 from Angel Li (angel@flipper.miami.edu).

 735
 736         * messages.c New function: as_bad  This is like as_warn, except
 737         -W doesn't disable it, and calling it inhibits production of an
 738         object file and causes a non-zero exit code.
 739

 774         correct addressing mode and byte-order for broken-word stuff.
 775

 792
 793         * atof-generic.c (atof_generic)  Ignore trailing zeroes after a decimal
 794         point.  For some reason trailing zeroes (but not trailing nonzeroes) were
 795         causing loss of precision.  I don't know why. . .
 796
 797         * vms.c Change copyright notice.  Install changes from Kenneth Adelman
 798         (adelman@tgv.com) for c++?  (A dozen lines or so)

 814
 815         * atof-m68k.c (atof_m68k)  Don't put the bits[] array on the stack,

 827         * vax.c (all)  Ran vax through indent -gnu to make it readable.
 828
 829         vax.c (vip_op)  Correctly assemble code like jmp $*0x11223344
 830         by setting vip_nbytes to 4 when using an immediate address.
 831         I hope this works!
 832
 833         m68k.c (s_proc (new))  Added s_proc no-op pseudo-op.
 834
 835         Makefile  Added instructions for compiling on Sequent Symmetry
 836         and HP 9000/300.
 837
 838         a.out.h Modified to compile on Sequent and HP above.  (HP port

 855         on the text /* ****/
 856
 857         * sparc.c (sparc_ip):  Don't abort on insns that use the Alternate

 869         * atof-ns32k.c  Include as.h so that sysV stuff (bzero) will be
 870         defined if needed.  These ns32k changes from
 871         nixbur!mollers.pad@seismo.css.gov (Josef Moellers)

 890

 900
 901         * Makefile: Removed $< references that seem
 902         to choke some versions of make.
 903
 904         * frags.c (frag_grow): Fixed to deal with requests for very
 905         large frags (larger than frags.chunk_size).
 906
 907         * app.c (do_scrub_next_char): Have it ignore any characters
 908         after the filename in a # line "filename".
 909
 910         * sparc.c (s_common): On an error, don't print out
 911         input_line_pointer past the end of the line where the error is.
 912
 913         * atof-generic.c (atof_generic): Accept any case for
 914         inf and nan.
 915
 916         * m68k.c (m68_ip): Don't use PC-relative mode for alterable

 923
 924 Fri Aug 11 16:01:16 1989  Roland McGrath  (roland at apple-gunkies.ai.mit.edu)
 925
 926         * sparc-opcode.h (struct sparc_opcode): Replaced `mask' field with
 927         `lose'; removed `last' field.  Updated all opcodes accordingly.
 928         Fixed several opcodes that generated the wrong instructions.
 929         sparc.c (md_begin, sparc_ip): Changed to use new struct sparc_opcode.

 931 Thu Aug  3 14:44:24 1989  Jay Fenlason  (hack at apple-gunkies.ai.mit.edu)
 932

 941
 942         * sparc.c (comment_chars[]): Removed '|' because it was causing
 943         problems.  Probably not the best fix, since I suspect other
 944         assemblers (68020) may get | in .stabs also, and the 68020 needs
 945         the '|' comment character.

 955
 956         * sparc-opcode.h: Added duplicate [i+1] entries to go with
 957         the [1+i] entries already there.  A kludgy fix, but it works.
 958
 959 Mon Jul 24 17:20:03 1989  Jay Fenlason  (hack)
 960
 961         * write.c (relax_segment): Modified rs_org code so it won't
 962         occasionally dump core.
 963
 964         * write.c (pseudo_set): Modified SEG_DIFFERENCE to (perhaps)
 965         allow one to set a symbol to the difference of two other symbols.
 966

 983
 984         * atof-generic.c: Fixed type in #ifdef __GNUC__.
 985
 986         * sparc-opcode.h: Handle "mov REG, %y".
 987
 988         * make-gas.com: Know that error.c no longer exists.
 989
 990         * sparc.c: Handle [expr+reg].
 991         Don't call getExpression when looking for an immediate and getting
 992         something that starts with % and isn't %hi or %lo.

1013         * make-gas.com, version.c, hex-value.c, flonum-const.c: VMS fixes.
1014

1040         the various descriptions.
1041
1042         * m68k.c (add_fix): Replace occurrences of "width==" with
1043         "(width)==".  This correct a precedence problem.

1052         defined as a .comm and is now trying to be defined locally.
1053         Also, redefining a symbol is a fatal, not a warning.
1054
1055         * m68k.c: Fixed a bug in using bignums as literal bit patterns for
1056         floating-point numbers.

1272
1273         * Added patches from pace to files as.h i386.c i386-opcode.h
1274           imull foo,%eax no longer gets assembled into the 32-64 bit
1275           multiply, which clobbers %edx behind gcc's back
1276
1277           jcxz/jecxz were backwards
1278
1279           There was a bug when using %ebp as a base register with no
1280           displacement
1281
1282           Instructions like andb $0xffffff, %al used to put out too many
1283           immediate bytes
1284
1285           The splitting jump instructions across frags could happen when
1286           obstack_room()==6 too.
