   2
   3         * app.c (app_push): Use memcpy, not bcopy.
   4         (do_scrub_next_char): For \", return " not '.
   5         (symbol_chars): Now const.
   6
   7         * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
   8         and "0b".  If LOCAL_LABELS_DOLLAR, check for "0$".
   9
  10         * config/obj-coff.h: Don't use #elif.
  11
  12         * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
  13         have it.  (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
  14
  15 Wed Dec 16 12:12:33 1992  Ian Lance Taylor  (ian@cygnus.com)
  16
  17         * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is
  18         already defined.
  19
  20 Tue Dec 15 12:40:11 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
  21
  22         * app.c (do_scrub_begin): allow single quote strings if so
  23         configured.
  24
  25         * config/*z8k*: checkpoint
  26
  27 Sun Dec 13 00:04:38 1992  Ian Lance Taylor  (ian@cygnus.com)
  28
  29         * read.c (read_a_source_file): avoid calling xmalloc (0).
  30
  31 Sat Dec 12 15:26:34 1992  Ian Lance Taylor  (ian@cygnus.com)
  32
  33         * listing.c: Call xmalloc, not malloc; don't declare malloc.
  34
  35         * Changes to support SCO 3.2v4:
  36         * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
  37         SEG_BSS, fill with NOP_OPCODE.
  38         * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
  39         * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
  40         using ZERO_BASED_SEGMENTS.
  41         (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
  42         never set segment address for SEG_E2 (.bss) and don't write out
  43         SEG_E2 contents.  Set .init and .fini sections to STYP_TEXT.
  44         (obj_coff_endef): Don't merge labels or symbols awaiting forward
  45         definitions, and don't merge tags with non-tags.  Check for .bf
  46         rather than just checking whether the second character is b and
  47         the third character is f.
  48         (obj_coff_val): gcc can generate values which we don't handle
  49         correctly; discard information for now, since it only affects the
  50         debugging information.
  51         (tag_find_or_name): Don't insert tags in the symbol table.
  52         (yank_symbols): Don't merge labels.
  53         (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
  54         already defined.  Fill subsegments with NOP_OPCODE, not 0.  Don't
  55         set segment address if ZERO_BASED_SEGMENTS.
  56         (obj_coff_section): Accept and ignore a trailing quoted string, as
  57         used in AT&T i386 syntax.
  58         (fixup_segment): Take segment as argument.  On the i386, adjust PC
  59         relative addends by the segment vaddr.
  60         * tc-i386.h: Define SUB_SEGMENT_ALIGN.
  61         * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
  62         * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

  75         * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
  76         and leave everything else alone.

  79
  80         * Makefile.in (as.new): Don't bother saving as.old.

 211         (insert_reg): put REGISTER_PREFIX before register names before
 212         putting them in the symbol table.
 213         * tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not
 214         M68KCOFF.
 215
 216         * obj-coffbfd.c (fill_section): set STYP_NOLOAD bit for .bss
 217         section.
 218
 219         * atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
 220         comment_chars, line_comment_chars and line_seperator_chars
 221         consistently const, and always initialized them.  Included read.h.
 222
 223 Thu Nov  5 17:55:41 1992  Jim Wilson  (wilson@sphagnum.cygnus.com)
 224

 228
 229 Wed Nov  4 07:50:46 1992  Ken Raeburn  (raeburn@cygnus.com)
 230
 231         * obj-coff.c (callj_table): Delete global variable.
 232         (obj_emit_relocations): Define it locally here, and only if
 233         TC_I960 is defined.
 234
 235         * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.
 236         (m68k_ip): Don't warn about bignum used as float bit-pattern.
 237
 238         * obj-coff.c: Replaced ANSI and non-ANSI function declarations
 239         with a single set using PARAMS macro.
 240
 241         * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length
 242         of 2.
 243
 244         * tc-i960.c: Missed a couple of 0->NO_RELOC conversions.
 245
 246         * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
 247         so widening works consistently.
 248
 249 Wed Oct 28 08:52:34 1992  Ken Raeburn  (raeburn@cygnus.com)
 250
 251         * version.c: Put conditional "const" before version_string, not
 252         before dummy function for VMS.  Now version 1.91.03.
 253
 254         * app.c (do_scrub_next_char): Need double-\ before `000' to show
 255         printed rep of null character.
 256
 257 Fri Oct 23 14:40:38 1992  Ian Lance Taylor  (ian@cygnus.com)
 258
 259         * obj-coffbfd.c (write_object_file): check return value of
 260         bfd_close_all_done.
 261
 262 Tue Oct 20 12:18:08 1992  Ian Lance Taylor  (ian@cygnus.com)
 263
 264         * Support for i386-sysv.
 265         obj-coffbfd.c (do_relocs_for, write_object_file): set segment
 266         addresses to reasonable sizes.  New define ZERO_BASED_SEGMENTS can
 267         be used to set them all to zero as was done before.
 268         (fill_section): segment addresses now set in write_object_file.
 269         (fill_section): Don't set STYP_NOLOAD for .bss section.

 277 Sat Oct 10 12:33:45 1992  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)
 278
 279         * configure.in: differentiate between SunOS 4 and Solaris2 for Sun4
 280         hosts, use the sysv configuration for solaris2
 281
 282 Mon Oct  5 09:28:57 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
 283
 284          fix i960+non-bfd coff bit rot.
 285         * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
 286         support for C source listings. (obj_coff_endef): look in the right
 287         part of the symbol for the symbol name
 288
 289         * tc-m68k.c (get_num): make it work for all segments, not just the
 290         first three.
 291
 292 Mon Oct  5 03:30:36 1992  Mark Eichin  (eichin at tweedledumber.cygnus.com)

 299
 300 Tue Sep 29 12:22:52 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
 301
 302         * obj-coffbfd.c (write_object_file): don't fixup for the z8k
 303         * tc-z8k.c: lots of bug fixes
 304
 305 Tue Sep 29 10:51:55 1992  Ian Lance Taylor  (ian@cygnus.com)
 306
 307         * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
 308         #elif, since it is not supported by old compilers.
 309         ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
 310         couple of expressions in tc-m68k.c.
 311
 312 Mon Sep 28 21:18:24 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 313
 314         * read.c (cons): If NO_RELOC is defined, use it.
 315
 316         * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
 317
 318 Fri Sep 25 18:18:52 1992  Ian Lance Taylor  (ian@cygnus.com)
 319
 320         * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
 321         local labels to start with a .) and set REGISTER_PREFIX to %.
 322         tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
 323
 324 Fri Sep 25 17:53:43 1992  John Gilmore  (gnu@cygnus.com)
 325
 326         * messages.c:  Comment changes.
 327
 328 Fri Sep 25 14:12:58 1992  Ken Raeburn  (raeburn@kyriath.cygnus.com)
 329
 330         * as.h: Test if __STDC__ is defined only, don't test its value.
 331         * messages.c: If __STDC__ is not defined, define NO_STDARG.
 332
 333 Thu Sep 24 12:42:32 1992  Brendan Kehoe  (brendan@rtl.cygnus.com)

 337
 338 Tue Sep 22 13:02:07 1992  Sean Eric Fagan  (sef@cygnus.com)
 339
 340         * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
 341         sections starting from zero, rather than making them consecutive.
 342         This makes subsequent reloc calculations easier, esp if the object
 343         format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
 344         allocate lcomm in .data rather than in .bss.  It seems that some
 345         tools can't cope with a non-zero sized bss before linkage.
 346
 347 Tue Sep 22 15:10:51 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 348
 349         * tc-m68k.c: Replace "enum m68k_architecture" with "int"
 350         throughout.  That enum no longer means what we thought it meant.
 351
 352         * tc-m68k.c (md_assemble, md_parse_option): Handle new
 353         "-mno-688[58]1" options.
 354

 373         * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
 374         .word is < -32768 or > 32767.  The -J flag causes the error to be
 375         ignored.  This is to catch over-sized switches generated by gcc on

 413          Motorola and MIT syntax; gas can now assemble either type of
 414          file.
 415         tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

 452 Tue Aug 25 15:50:48 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 453
 454         * config/tc-m68k.c (init_table): Now const.  Always include 68851
 455         data, so that "bc" is available to 68040 cache instructions.
 456         Added "tt0", "tt1", and 68ec030 variants.
 457         (md_assemble): Complain if 68000 (only) and 68881 are specified.

 480
 481         * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB

 493         written with indirection on the last two operands, which can be
 494         either data or address registers.  Added a new operand type 'r'
 495         which accepts either register type.  Added '(' to notend stuff in
 496         tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

 703         * config/obj-a.out (s_sect): complain if the user tries to use a
 704         subsegment with a value which might interfere with out -R hackery.
 705         * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
 706         rather than use ugly if tree. (init_regtable): insert register
 707         names into symbol table.

 710
 711         * write.c (write_object_file): keep the fix_tail clean, which
 712         fixes a bug in -R where relocations were being lost.

 736
 737         * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
 738         calc the base of relocs correctly.
 739         * tc-a29k.c (parse_operand): allow expressions to be in any section.
 740
 741 Mon Apr 27 13:13:31 1992  K. Richard Pixley  (rich@cygnus.com)
 742
 743         * as.c, write.c: use -K rather than -k for the broken word warning
 744           option.
 745

 753
 754 Tue Apr 14 14:50:22 1992  Ken Raeburn  (Raeburn@Cygnus.COM)
 755
 756         * write.c (write_object_file): For b.out format, round up section
 757         start addresses to match required alignment.
 758
 759 Thu Apr  9 05:45:29 1992  Ken Raeburn  (Raeburn@Cygnus.COM)
 760
 761         * Makefile.in (install): Install into $(tooldir)/bin, since that's
 762         where gcc looks for it.
 763
 764 Tue Apr  7 15:12:15 1992  Sean Eric Fagan  (sef@cygnus.com)
 765
 766         * Makefile.in:  Changed some lines to be less confusing for some
 767         makes.
 768

 784 Fri Mar 13 08:03:03 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
 785
 786         * flonum-const.c: renamed flonum-konst.c to stop dos name

 790
 791         * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
 792           tc-m68k.h to te-sun3.h.
 793
 794 Wed Mar 11 23:32:42 1992  K. Richard Pixley  (rich@cygnus.com)
 795
 796         * configure.in: vxworks68 gets te-sun3.h.
 797
 798         * expr.c: remove limitation that local_labels_dollar or
 799           local_labels_fb must be < 10.
 800
 801         * symbols.c: remove local_labels_dollar, replace with a function
 802           interface for a sparse array.  All users adjusted.
 803
 804         * te-sun3.h: add LOCAL_LABELS_DOLLAR.
 805
 806 Fri Mar  6 21:57:18 1992  K. Richard Pixley  (rich@cygnus.com)
 807
 808         * Makefile.in: added check target.
 809
 810 Tue Mar  3 15:45:56 1992  K. Richard Pixley  (rich@rtl.cygnus.com)
 811

 813
 814 Sun Mar  1 04:43:19 1992  Michael Tiemann  (tiemann@cygnus.com)
 815
 816         * write.{c,h} (fix_new): Make these declarations consistent.
 817
 818 Sat Feb 29 13:59:10 1992  Michael Tiemann  (tiemann@cygnus.com)
 819
 820         * Makefile.in (strerror.o): Add rule so that broken Sun make can
 821         work in subdirs.
 822
 823 Wed Feb 26 19:26:28 1992  Steve Chamberlain  (sac at thepub.cygnus.com)
 824
 825         * read.c, obj-coffbfd.c : fix h8300 specific bit rot
 826
 827         * expr.c (operand): if can't work out what sort of operand it is,
 828         then look through FLT_CHARS for a hint.
 829
 830 Wed Feb 26 18:04:40 1992  K. Richard Pixley  (rich@cygnus.com)
 831
 832         * Makefile.in, configure.in: removed traces of namesubdir,
 833           -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
 834           copyrights to '92, changed some from Cygnus to FSF.
 835
 836 Tue Feb 25 14:17:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 837
 838         * expr.c: If an expression is single comma, then return with
 839         SEG_ABSENT rather than an error - since the sparc front end does
 840         really strange things with things like fbge,a
 841
 842         * as.h: include bfd.h if using many sections
 843         * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
 844         local labels didn't work.
 845         * listing.c (list_symbol_table): don't core dump when there's no
 846         symbol there.
 847         * write.c, write.h: call fix_new with the right number of args on
 848         the H8.
 849         * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
 850         errors nices
 851
 852 Sat Feb 22 12:26:28 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 853
 854         * app.c: MRI compatibility - allow single quote to start a string.
 855         * as.c: fix typo recently introduced.
 856         * as.h : Don't include aout/reloc.h - it's not right for COFF!
 857         * expr.c: Much rewriting, to accomodate MRI syntax for
 858         expressions. Also easier to read now.
 859         * listing.c: Put back defuns
 860         * read.c: modified to accept MRI syntax, put back listing pseudo
 861         ops so that an assembler built with NO_LISTING ignores list ops
 862         rather than pukes.
 863         * write.c, write.h: fixs - only keep a reloc type in a fix if the target
 864         machine is a SPARC or a 29K.
 865         * config/obj-aout.c: added s_sect pseudo op
 866         * config/obj-coffbfd.c: lints, set the filehdr flags right and
 867         fill in the timestamp.
 868         * config/obj-coffbfd.h: Since we don't include aout/reloc.h
 869         anymore, define all the relocs which the tc-<x> bit will use so we
 870         can translate from them to the coff types.
 871         * config/tc-a29k.c: reloc_type isn't ane enum any more
 872         * config/tc-m68k.c: Added NO_RELOC definition.
 873
 874 Fri Feb 21 06:21:07 1992  K. Richard Pixley  (rich@rtl.cygnus.com)
 875
 876         * Makefile.in: put header files before C source for TAGS; remove
 877           references to non-existent syscalls.h.
 878
 879         * read.c, write.c subsegs.c: back out the .bss changes.
 880
 881         * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
 882
 883         * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
 884
 885         * a.out.h: removed.
 886
 887 Fri Feb 21 01:08:48 1992  Minh Tran-Le (TRANLE@INTELLICORP.COM)
 888
 889         * symbols.c (local_label_name): symbols now start with ^A.
 890
 891         * read.c, subsegs.c, write.c obj-coff.c: added handling of
 892           `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
 893           generate these sections.  .align: will use NOP_OPCODE or 0
 894           for padding. This is just for being nice to the
 895           disassembler.
 896
 897         * expr.c (operand): changed to generate local label "\001L0"
 898           starting with a ^A so that it is recognized as a local label.
 899
 900         * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
 901
 902         * tc-i386.c: tc-i386.c: added handling of the following opcodes:
 903           i/o opcodes - inb, inw, outb and outw.  string manipulation with
 904           att syntax - scmp, slod, smov, ssca, ssto.
 905
 906         * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
 907           to just after .file .
 908
 909           In obj_crawl_symbol_chain() where it tries to put the external
 910           symbols apart, with the condition:
 911             (!S_IS_DEFINED(symbolP) &&
 912              !S_IS_DEBUG(symbolP) &&
 913              !SF_GET_STATICS(symbolP))
 914           it was moving too many symbols out. So I switch it back to the
 915           condition:
 916             (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
 917
 918           In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
 919           so that we don't use the F_RELFLG which make the linker complain
 920           that somebody has stripped the relocation info.
 921
 922           Also, the AIX ld program require that the relocation table
 923           is sorted by r_vaddr like the standard ATT assembler does.
 924
 925           [he also changed the sizeof(struct ...)'s into the coff
 926           style FOOSZ macros.  I'm not sure this is right, but I can't
 927           remember why.  xoxorich.]

 929 Fri Feb 21 01:08:48 1992  K. Richard Pixley  (rich@cygnus.com)
 930
 931         * Makefile.in, configure.in, doc: use the doc.  Build it, install
 932           it, clean it, etc.
 933
 934 Tue Feb 18 02:21:25 1992  K. Richard Pixley  (rich at cygnus.com)
 935
 936         * read.c: white space and comments only.
 937
 938         * configure.in: use the new atof-ns32.c for ns32k.
 939
 940         * write.c: comment change only.
 941
 942         * tc-m88k.[hc]: pulled in from hack's unfinished work.  These
 943           aren't yet integrated.
 944
 945         * tc-i860.[hc]: blew off the dust.  Something must still be done
 946           about conflicting relocation types.
 947
 948         * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
 949           real thing.
 950
 951         * tc-i960.c, tc-sparc.c: white space and comments only.
 952
 953         * tc-a29k.h: delete duplicate macro definition.
 954
 955         * new file atof-ns32k.c copied from hack's last unreleased gas.
 956
 957 Mon Feb 17 07:51:06 1992  K. Richard Pixley  (rich at cygnus.com)
 958
 959         * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
 960           rather than abort.
 961
 962         * nearly everything.  flush ChangeLog, package as gas-1.92.1.
 963           ChangeLog's prior to this are sketchy at best.  I have logs.
 964           They just aren't ChangeLogs.
