   1 Sat Jan  4 16:34:16 1992  John Gilmore  (gnu at cygnus.com)
   2
   3         * as.h:  Move redefine of xfree.
   4         * config/ho-generic.h:  Declare free(), since it's used without
   5         ()s in obstack_begin.
   6         * read.c:  Use xmalloc, not malloc.
   7         * expr.c, input-scrub.c, write.c:  Avoid "know" macros
   8         that cover more than one line, since this causes char strings
   9         with embedded newlines.
  10
  11 Wed Dec 11 18:13:07 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
  12         * configure.in: handle rename of obj-coffbfd
  13         * config/obj-coffbfd.c: lint, don't fixup relocs if H8300, use
  14         tc_reloc_mangle to prepare relocation if one available
  15         * config/tc-h8300.h: added tc_reloc_mangle routine
  16

  18
  19         * input-file.c: don't close a NULL file pointer.
  20

  34
  35 Thu Dec  5 22:46:23 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
  36
  37         * Makefile.in: idestdir and ddestdir go away.  Added
  38           copyrights and shift gpl to v2.  Added ChangeLog if it
  39           didn't exist. docdir and mandir now keyed off datadir by
  40           default.
  41
  42 Wed Dec  4 10:28:48 1991  Steve Chamberlain  (sac at cygnus.com)
  43
  44         * config/obj-coff-bfd.c (crawl_symbol_chain): only move a
  45         symbol to the end of a file if it really is external.
  46
  47
  48 Sat Nov 30 23:03:59 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
  49
  50         * as.h: reloc.h->aout/reloc.h.
  51         * a.out.gnu.h: reloc.h->aout/reloc.h
  52
  53 Thu Nov 28 13:21:41 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
  54
  55         * config/obj-coff-bfd: made multiple sections with subsections
  56         work.
  57         * config/tc-h8300.c: made $ statement sep, and int alloc 2 bytes.
  58
  59
  60 Mon Nov 25 17:26:22 1991  Steve Chamberlain  (sac at cygnus.com)
  61
  62         * as.c: (perform_an_assembly_pass): moved declaration of i to
  63         avoid a syntax error. Now always create the three default
  64         sections when in MANY_SEGMENTS mode.
  65         * as.h: New improved way of specifying MANY_SEGMENTS
  66         * configure.in: hds object format is now coff-bfd
  67         * subsegs.h: add line numbers and section stuff to the
  68         segment_info structure. (But go back later and fix.. this is
  69         COFF specific)
  70
  71
  72 Thu Oct 24 17:25:59 1991  Steve Chamberlain  (steve at rtl.cygnus.com)
  73
  74         * config/obj-coff.c (obj_coff_dim): Allows newline to end a
  75         .dim statement.
  76
  77 Mon Oct 21 09:25:33 1991  Steve Chamberlain  (steve at rtl.cygnus.com)
  78
  79         * configure.in: added ebmon entry.
  80         * output-file.c (output_file_create, output_file_close) added
  81         stuff to use bfd.
  82         * write.c: more bfd support
  83         * config/obj-coff.c  config/obj-coff.h use bfd for swapping
  84         header info.
  85         * tc-a29k: added the reloc types we support now
  86
  87
  88 Mon Oct 14 11:44:03 1991  Roland H. Pesch  (pesch at cygnus.com)
  89
  90         * doc/Makefile (as.ms): one more sed workaround for texi2roff
  91         (as.mm, as.me): new targets
  92
  93 Fri Oct 11 18:18:37 1991  Roland H. Pesch  (pesch at cygnus.com)
  94
  95         * doc/Makefile: new targets as.info, as.ms
  96         doc/as.texinfo: minor changes for texi2roff-2
  97         Makefile.in: revise 'doc' target.
  98
  99 Fri Jan  4 12:48:22 EST 1991    Jay Fenlason (hack@ai.mit.edu)
 100
 101         * messages.c  Moved as_perror from input-scrub.c  Modified the
 102         error messages to look better.
 103
 104         * output-file.c Don't call as_fatal, just call exit()
 105
 106         expr.c Slightly improve checking for foo-foo case in
 107         clean_up_expression().  Detect foo: bar: ... foo-bar...
 108
 109 Tue Dec  4 16:29:20 EST 1990    Jay Fenlason (hack@ai.mit.edu)
 110
 111         * m68k.c  Fixed an obscure bug involving AOFF mode with a
 112         large constant displacement (Was forgetting to output the
 113         extension word.)
 114
 115         make-gas.com  Added a three line patch from Eric Youngdale that
 116         makes it possible to submit make-gas.com to a batch queue.
 117
 118 Wed Nov 21 15:07:51 EST 1990    Jay Fenlason (hack@ai.mit.edu)
 119
 120         * vms.c  (VMS_TBT_Routine_END)  Add a four line patch from
 121         Eric Youngdale.
 122
 123 Tue Nov 13 14:02:15 EST 1990    Jay Fenlason (hack@ai.mti.edu)
 124
 125         * vms-dbg.c (VMS_DBG_record())  Another one character patch from
 126         Eric Youngdale.
 127
 128 Mon Oct 29 15:49:21 EST 1990    Jay Fenlason (hack@ai.mit.edu)
 129
 130         * read.c  Replace some as_warn calls with as_bad.
 131
 132 Fri Oct 26 15:21:15 EDT 1990    Jay Fenlason (hack@ai.mit.edu)
 133
 134         * i386.c, i860.c, ns32k.c       Add const changes.
 135
 136 Mon Oct 22 14:04:26 EDT 1990    Jay Fenlason (hack@ai.mit.edu)
 137
 138         * sparc.c       Add const changes.
 139
 140         * make-gas.com  define const= for VMS, since many older versions of
 141         GCC don't work correctly with const under VMS.
 142
 143 Thu Oct 18 12:44:11 EDT 1990    Jay Fenlason (hack@ai.mit.edu)
 144
 145         * i860.c i860-opcode.h  Added patches from rgb@mcc.com
 146
 147         * read.c, symbols.c, vms.c, + new_file vms-dbg-module.c
 148         Added Eric Youngdale's <YOUNGDALE@v6550c.nrl.navy.mil> VMS debugging
 149         patches, so debugging GCC output now works.
 150
 151         * hash.c (hash_grow)  Remember to blank out the wall entry in the new
 152         hash table.  This is important on systems where malloc() returns
 153         non-zero storage. . .
 154
 155 Tue Oct 16 10:11:35 EDT 1990    Jay Fenlason (hack@ai.mit.edu)
 156
 157         * output-file.c (output_file_create)  if output filename is given as
 158         '-', write to stdout.
 159
 160         * m68k.c Finally get the PCREL code to work right.  Add relaxation of
 161         PCREL stuff  This small fix from Ken Woodland
 162         (kenny%datacube.uucp@uunet.uu.net).
 163
 164         * m68k.c  Added some const declarations to constants.  (md_relax_table,
 165         md_pseudo_table, etc. . .)
 166
 167 Thu Oct 11 11:15:10 EDT 1990    Jay Fenlason (hack@ai.mit.edu)
 168
 169         * Makefile, read.c, write.c Include the i860 port.
 170         (New files i860.c i860-opcode.h i860.h)
 171
 172         * m68k.c Fix some addressing modes, (AOFF, AINDEX, etc) to work in
 173         PC relative mode.
 174
 175         * (all over)  Raeburn's const hacking.  This reduces the data-space size by
 176         declaring many tables, etc, as 'const'.
 177
 178 Mon Oct 22 22:48:22 1990  John Gilmore  (gnu at cygint)
 179
 180         Make gas work if you turn on the know() checks.
 181
 182         * app.c:  Only pass a single space through:  the one after
 183         the opcode.  All other whitespace is removed, to match the
 184         expectations of the parser in read.c.
 185
 186         * as.h: Remove obsolete comments.  Remove JF's NDEBUG so
 187         that know() can really work if you turn it on.  Make
 188         SEG_MAXIMUM_ORDINAL == SEG_REGISTER.
 189
 190         * expr.c (operand):  Change BITS_PER_INT to 8*sizeof(int).
 191
 192         * input-scrub.c:  strlen("\0") doesn't return 1...
 193         (as_where):  Add space after line number in errors, like gcc.
 194
 195         * m68k.c (s_bss):  Fake .bss into data section 255.
 196         We can't cope with a real "BSS section" yet, but we can at
 197         least do the right thing less efficiently (with lots of
 198         zeroes).
 199
 200         * read.c:  Turn lots of as_warn()'s into as_bad()'s.
 201
 202         * read.h (SKIP_WHITESPACE):  Replace last instance of ASSERT()
 203         with know().
 204
 205         * sparc.c (s_seg):  We can't put frags into the BSS segment
 206         yet, so just fake bss seg as 255th data segment.
 207
 208         * vax.c:  Remove \'s from continued macro *parameters*.  These
 209         must have been added after the last time someone turned on
 210         know() checking...
 211
 212         * write.c (relax_segment):  Refine what we know() about the
 213         symbols referenced during relaxation.
 214
 215         * Makefile (OTHER_ALIGN):  Remove, handled in tables now.
 216         Flip options a bit.  These options really ought to go
 217         elsewhere.
 218
 219 Sun Oct 21 03:57:21 1990  John Gilmore  (gnu at cygint)
 220
 221         Sun-3 fixes.
 222
 223         * expr.c, write.c:  Missing semicolon after know().
 224
 225         * write.c (fixup_segment):  Allow pc-relative accesses to undefined
 226         external symbols.  Previously this would turn off pc-rel calc
 227         of displacement, while leaving pc-rel opcode alone, botching.
 228
 229         * m68k.c (m68k_ip):  Allow pc-relative effective addresses
 230         for source operands.  "pea" instructions are a good example
 231         where we can shorten from abs long to pc+16bit.
 232         (md_convert_frag):  Fix "JBSR" comments to refer to "JSR", the
 233         actual instruction.  Insert comments about bug in 68000 bcc
 234         and dbcc long code (that doesn't get exercised much).  Add
 235         comments about long pcrel displacements for -pic.  Remove
 236         "this code has not been tested" comment.
 237         (md_estimate_size_before_relax):  Now that fixup_segment
 238         doesn't shortcircuit pc-relative fixups for undefined symbols,
 239         only output them if -pic; else turn them absolute, which is
 240         slightly faster.  More JBSR->JSR comments.
 241         (md_parse_options):  Parse -pic.
 242
 243 Fri Oct 19 14:35:20 1990  John Gilmore  (gnu at cygint)
 244
 245         * Make sparc assembler more compatible with Sun assembler.
 246         sparc.c:  reformat pseudo-op table to match main table.
 247         (md_assemble):  Add SPECIAL_CASE_FDIV to assemble FDIV*
 248         instructions as fdiv followed by fmovs to get around chip bug.
 249         (s_common, s_seg):  Accept "bss" section name.
 250         (md_assemble):  Handle "set" instructions with absolute
 251         operands, that only take one instruction rather than two.
 252         sparc-opcode.h (fdiv*):  Mark instructions "S"pecial.
 253         subsegs.c (subseg_change):  Move tail pointer too.
 254         symbols.c (colon):  Allow new definitions to override .comm symbols,
 255         as in VMS.  Sun CC depends on this.
 256         write.c (new_fix):  Always take r_type argument, not just on sparc.
 257         Chain fixP's in order, using tail pointer, so relocation
 258         records come out in forward order like Sun as.  Remove SPARC
 259         ifdefs.
 260         write.h: Add seg_fix_tailP, data_fix_tailP, text_fix_tailP.
 261
 262         * am29k.c: Use s_align_bytes rather than a local copy.
 263
 264         * read.c (s_align):  Rather than ifdef it, make two functions,
 265         s_align_bytes and s_align_ptwo.  Individual pseudo-op tables
 266         can call whichever one they like.
 267
 268         * write.c (append):  Move from append.c to here.
 269         append.c:  Remove file.
 270
 271         * Makefile (MDSRC, mdsrc):  Easy way to edit all md.c's.
 272         Fix options.  Add option for -DDEBUG for know() and assert().
 273         Remove append.c, am29k.h.  Don't build special read-sparc.o.
 274         Remove sparc.h.  "make clean" removes am29k .o's.  Add
 275         dependencies on reloc.h.
 276
 277 Thu Oct 18 17:56:34 1990  John Gilmore  (gnu at cygint)
 278
 279         * Generalize sparc extensions to relocation info.  Gas now
 280         keeps relocation information internally in a different format
 281         than how it is stored in the resulting .o.  md_ri_to_bytes()
 282         converts to external format.  md_reloc_size says how large
 283         each relocation record is in external format.
 284         sparc.h:  Remove this file.  Rename to reloc.h.  Rename struct
 285         to reloc_info_generic.
 286         reloc.h:  Add relocation types for AMD 29000.
 287         read.c, write.c:  Always call fix_new with reloc-type argument.
 288         write.c (emit_relocations): Make md_ri_to_bytes write directly
 289         to output area rather than overwriting its argument then
 290         bcopying it.
 291         md.h:  Declare md_reloc_size and md_ri_to_bytes.
 292         i386.c, am29k.c, vax.c, ms32k.c, m68k.c, sparc.c: include reloc.h.
 293         (md_reloc_size): Specify correct value.
 294         (md_ri_to_bytes):  Convert format from internal to external.
 295
 296         write.c (write_object_file):  Call md_section_align() which
 297         rounds section sizes up if desired.
 298         sparc.c (md_section_align):  Round to 8 byte boundary.
 299         i386.c, am29k.c, vax.c, ns32k.c, m68k.c (md_section_align):  Nop.
 300
 301 Mon Oct 15 22:06:11 1990  John Gilmore  (gnu at cygint)
 302
 303         Changes in support of the AMD 29000 version of gas.
 304
 305         * am29k-opcode.h:  Add dummy entry to end so we can examine
 306         item N+1 without exceeding table.
 307
 308         * am29k.h:  New include file, derived from sparc.h.  Kludged
 309         together, still needs major work to get relocation working.
 310
 311         * am29k.c:  New file, derived from sparc.c.
 312         Put 29k-specific ASM29K pseudo-ops into table.
 313         Change comment_chars to ASM29K.
 314         Change s_seg to s_use.
 315         Change s_sparc_align to s_29k_align, default operand to 4.
 316         (define_some_regs):  Define special register names.
 317         (md_begin):  Preprocess opcode table to mash together all
 318         the variants of single opcodes.  This simplifies later handling.
 319         Call define_some_regs to preset special reg names.
 320         (parse_operand):  Add, parses out an operand from a stmt.
 321         (machine_ip):  Simplify, since 29K is simpler asm language.
 322         Handle the various keyletters in the opcode table.
 323
 324
 325         Handle include files in the assembler, with a .include
 326         pseudo-op.
 327         * as.h (input_scrub_include_file):  declare.
 328         * as.c (perform_an_assembly_pass):  Avoid buffer hacking.
 329         Start us off in text segment.
 330         * read.c (read_a_source_file):  Take a name as argument,
 331         internalize all buffer handling.  Don't start a new text
 332         subsegment on each entry.  Actually use the start and end
 333         pointers returned by input_scrub_next_buffer.
 334         (s_include):  Call input_scrub_include_file for .include.
 335         * input-scrub.c:  Fix comments.
 336         (struct input_save):  Add, for saving state at .include.
 337         (input_scrub_push, input_scrub_pop):  Add, push & pop state.
 338         (input_scrub_begin):  Initialize next_saved_file.
 339         (input_scrub_end):  Free buffer.
 340         (input_scrub_include_file):  Add, to include a file.
 341         (input_scrub_close):  Add, to close a file.
 342         (input_scrub_next_buffer):  Set buffer-start address for
 343         caller.  If we hit EOF and were included, pop to previous file.
 344         * input-file.c:  Remove old includes.  Remove old file-descriptor
 345         hacking code, that was commented out.
 346         (struct saved_file):  Add, for saving state at .include.

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

 364         dependent) lexer table meanings.
 365
 366
 367         Encapsulate knowledge of segment types in fewer places.
 368         This allows us to add the "SEG_REGISTER" type, as well as
 369         providing flexibility for eventual COFF/ELF support.
 370         * struc-symbol.h (symbol_to_segment, symbol_to_segment_type,
 371         set_symbol_segment, set_symbol_segment_keep_ext,
 372         segment_name):  Define macros to encapsulate this info.

 376         write.c:  Use macros.
 377         * i386.c, m68k.c, ns32k.c, vax.c, write.c: Change 2nd arg type of

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

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

 471
 472         * as.c  #include <sys/types.h> if _POSIX_SOURCE defined.  This because
 473         <signal.h> uses pid_t that's defined in it.
 474
 475         * m68k.c reverse the sense of -l option, and allow :w and :l to
 476         override the default size of AOFF indexes.
 477
 478         Also, allow -l to shorten branches to unknown labels from LONG to WORD.

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

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

 833         I hope this works!

 857         on the text /* ****/
 858

 902
 903         * Makefile: Removed $< references that seem
 904         to choke some versions of make.
 905
 906         * frags.c (frag_grow): Fixed to deal with requests for very
 907         large frags (larger than frags.chunk_size).
 908
 909         * app.c (do_scrub_next_char): Have it ignore any characters
 910         after the filename in a # line "filename".
 911
 912         * sparc.c (s_common): On an error, don't print out
 913         input_line_pointer past the end of the line where the error is.
 914
 915         * atof-generic.c (atof_generic): Accept any case for
 916         inf and nan.
 917
 918         * m68k.c (m68_ip): Don't use PC-relative mode for alterable

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

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

 957
 958         * sparc-opcode.h: Added duplicate [i+1] entries to go with
 959         the [1+i] entries already there.  A kludgy fix, but it works.
 960
 961 Mon Jul 24 17:20:03 1989  Jay Fenlason  (hack)
 962
 963         * write.c (relax_segment): Modified rs_org code so it won't
 964         occasionally dump core.
 965
 966         * write.c (pseudo_set): Modified SEG_DIFFERENCE to (perhaps)
 967         allow one to set a symbol to the difference of two other symbols.
 968

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

1042         the various descriptions.
1043
1044         * m68k.c (add_fix): Replace occurrences of "width==" with
1045         "(width)==".  This correct a precedence problem.

1275         * Added patches from pace to files as.h i386.c i386-opcode.h
1276           imull foo,%eax no longer gets assembled into the 32-64 bit

1278
1279           jcxz/jecxz were backwards
1280
1281           There was a bug when using %ebp as a base register with no
1282           displacement
1283
1284           Instructions like andb $0xffffff, %al used to put out too many
1285           immediate bytes
1286
1287           The splitting jump instructions across frags could happen when
1288           obstack_room()==6 too.
