   8         LEX_IS_STRINGQUOTE, and LEX_IS_ONECHAR_QUOTE.
   9
  10         * config/te-irix.h: New file; irix needs a different LOCAL_LABEL

  45         (obj_ecoff_begin, obj_ecoff_bend): Ignore line number by reading
  46         it with get_absolute_expression, rather than skipping it by hand.
  47         (obj_ecoff_loc): If using stabs, just output a stabs symbol rather
  48         than ECOFF line number information.
  49         (obj_ecoff_stab): Accept non-zero values for stabs line number.
  50         (ecoff_build_symbols): Set ifilesym correctly.  Set storage class

  72         * as.c (main) [BFD_ASSEMBLER]: If errors occur, close and unlink
  73         the output file.
  74
  75         * doc/as.texinfo: Don't use @value in node names for the moment;

  77
  78         * as.h (const, volatile): Put these definitions back, and use
  79         them.
  80
  81         * doc/as.texinfo: First pass at using new texinfo features --

  83
  84 Mon Mar 29 16:05:40 1993  Ken Raeburn  (raeburn@cambridge.cygnus.com)
  85
  86         * read.c: Temporary hack to handle some 64-bit constants.  This

 107
 108         * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
 109         the bottom (make expands variables in dependencies when the

 111
 112         * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
 113         a29k .bss section; the mondfe program doesn't like it.
 114
 115 Sun Mar 28 08:12:53 1993  Ken Raeburn  (raeburn@kr-pc.cygnus.com)
 116
 117         * config/tc-m68k.c: Use PARAMS macro, and use CONST instead of
 118         const.

 123         * doc/none.m4: Define Z8000.
 124         * doc/Makefile.in (as-*.texinfo): Refer to $(srcdir).  Remove the
 125         texinfo file before recreating it.
 126         (TEXI2DVI): Need to set TEXINPUTS if "make as.dvi" is to work in
 127         this directory.
 128         (srcdir): Delete second, bogus definition.
 129         (as.info): Look for as-*.texinfo in current directory rather than

 131         (as.dvi): Ditto.
 132         (dvi): New rule.
 133         * doc/configure.in: Create links to all as-*.texinfo files in the

 137         number.
 138         (per-target): Classify i486 as i386.  Use generic cpu_type instead
 139         of target_cpu in selecting format etc.

 145         * configure.in: Adjusted.
 146
 147         * config/obj-bfd-sunos.*: Unused; deleted.
 148
 149         * Makefile.in (version.c, vers-stamp): Deleted.
 150         (config.h): Define GAS_VERSION.
 151         * as.c (version_string): Deleted declaration.
 152         (main): Look for GAS_VERSION instead.
 153
 154         * doc/as.texinfo: Updated description of -a* (listing) options,
 155         and describe how to pass them through from gcc.
 156
 157         * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
 158         process relocs if there aren't any relocs to process.  Avoids
 159         malloc/free bug on SCO too.
 160
 161         * as.h: Move local include files below system include files, to
 162         avoid some redefinition complaints on some systems.
 163         (const, volatile): Don't need these conditionally defined if we
 164         use CONST and VOLATILE from ansidecl.h.
 165         (seg_name): Use CONST, not const.
 166
 167 Fri Mar 26 10:22:04 1993  Ian Lance Taylor  (ian@cygnus.com)
 168

 170
 171 Thu Mar 25 08:59:14 1993  Ian Lance Taylor  (ian@cygnus.com)
 172
 173         * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
 174         (fixup_segment): Add a29k special case; the linker is not prepared
 175         to see a segment offset here.
 176
 177         * app.c (do_scrub_next_char): Added new state, 10, modifying state
 178         9 to only keep a space in between identifier characters.
 179
 180 Wed Mar 24 02:16:22 1993  david d `zoo' zuhn  (zoo at poseidon.cygnus.com)
 181
 182         * Makefile.in: add dvi target; as-$(config).texinfo might live in
 183         srcdir, might be in objdir.
 184
 185         * doc/Makefile.in: dvi depends on as.dvi
 186
 187 Mon Mar 22 23:59:13 1993  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)
 188

 196
 197         * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
 198         bignums, but don't emit error message.
 199
 200 Fri Mar 19 21:02:19 1993  Jim Wilson  (wilson@sphagnum.cygnus.com)
 201
 202         * Makefile.in (targ-cpu.o): Depend on config.h.
 203
 204 Wed Mar 17 16:44:06 1993  Ian Lance Taylor  (ian@cygnus.com)
 205
 206         * app.c (do_scrub_next_char): Added new state, 9, to avoid
 207         dropping a space immediately following an identifier.
 208         * expr.c, write.c: Rewrote assert expressions to not use multiple
 209         lines; I don't think that can be done portably.
 210         * config/tc-mips.c (macro): Use $AT if target register is zero in
 211         load instruction, which it can be for a floating point load.
 212

 214
 215         * write.c (write_contents): Compute the relocs before writing out
 216         the section contents.
 217         * config/obj-ecoff.h, config/obj-ecoff.c: Numerous changes to get
 218         symbol table and values right.
 219         * config/tc-mips.h (LOCAL_LABEL): If OBJ_ECOFF, any label starting
 220         with $L is local.
 221         * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
 222         by the section vma.
 223
 224         * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
 225         z8k-opc.h, not z8k.h.
 226
 227         * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
 228         symbol.

 231
 232         * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
 233
 234 Fri Mar 12 12:00:07 1993  Ian Lance Taylor  (ian@cygnus.com)
 235
 236         * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
 237         to be on a single line.

 240
 241         * Makefile.in (config.h): Create file, writing out definitions of
 242         target cpu, alias, and canonical name.
 243         (ALL_CFLAGS): No longer define TARGET_CPU.
 244
 245         * Makefile.in (check): Print a message, instead of quitting
 246         silently.
 247
 248         * as.c (main): Don't catch any signals, for now.
 249
 250         * version.c: Deleted.
 251         * Makefile.in: Generate it, putting in only the version number
 252         itself.
 253         (VERSION): New variable.
 254         * as.c: Include config.h.
 255         (main): Reformatted version string.  Include target alias.  Don't

 282         (struct loc, struct proc, struct file): Moved to tc-mips.c within
 283         #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
 284         * config/tc-mips.c: Rearranged for ECOFF support.  Added
 285         prototypes for all static functions.  Moved existing minimal
 286         debugging format support info #ifndef OBJ_ECOFF blocks.
 287         (macro_build_lui): Eliminated sign_extend argument, because ECOFF
 288         does not support a non sign extended high 16 bits reloc.  Adjusted
 289         all callers accordingly.
 290         (tc_get_register): Renamed from get_register, and made non-static.
 291
 292         * config/mips-big.mt, config/mips-lit.mt: New files.  Define
 293         TARGET_BYTES_BIG_ENDIAN and TARGET_BYTES_LITTLE_ENDIAN,

 305         * write.c (chain_frchains_together): Check that seg_info (section)
 306         is not NULL.
 307         (write_object_file): Call obj_frob_file after setting the symbols,

 321         read.c, config/obj-ieee.c, config/obj-tcm88k.c: Not any of these
 322         places.
 323
 324 Thu Mar  4 11:52:23 1993  Steve Chamberlain  (sac@thepub.cygnus.com)

 333
 334         Patches from Eric Youngdale:
 335         * make-gas.com: Find obstack.obj if it's not in the current
 336         directory.
 337         * read.c (s_ignore): Don't declare is_end_of_line.  It's
 338         redundant, and triggers a VMS gcc compiler bug.
 339
 340         * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
 341         current segment as an argument.  (Ignored in all cases but VMS.)
 342         All callers and definitions changed.
 343
 344 Tue Mar  2 11:56:19 1993  Ian Lance Taylor  (ian@cygnus.com)
 345

 681         * obj-vms.c: Patch to fix bug where we were not correctly parsing the
 682           stabs directives.
 683         * obj-vms.c:  Define macros COPY_LONG and COPY_SHORT which
 684           will swap bytes if needed on a big endian system.  Use throughout
 685           as needed.
 686         * obj-vms.c (obj_aout_stab):  Add code to generate listing file.
 687         * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
 688           types of malformed stabs.  Change parsing algorithm so that we are
 689           more certain of having all of the information that we need on hand.
 690         * obj-vms.c (final_forward_reference):  New function, used to help
 691           resolve the data types of as many struct elements as possible
 692           when some part of the struct is not fully defined by the compiler.
 693         * obj-vms.c (VMS_LSYM_Parse):  Correctly handle case of continuation
 694           stabs directives.
 695         * obj-vms.c (VMS_write_object_file): Define all vtable psects
 696           as symbols as well in the object file.  Look for external functions
 697           that start with "__vt.", and turn them into variables, since the
 698           g++ compiler is incapable of doing this.
 699         * tc-vax.c: Add '1' option for backward compatibility with older GCC
 700           versions.
 701         * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
 702         * input-scrub.c (as_where): Fix bug where as would crash if we did not
 703           have the name of the source file yet.
 704         * config/ho-vms.h: define HO_VMS, not HO_VAX.

 707
 708         * read.c (s_data): Always use "data_section", since it'll map to
 709         SEG_DATA or SEG_E1 if needed.
 710         (s_lcomm): Likewise with bss_section.
 711         (s_fill): Use memset, not bzero.
 712
 713 Thu Dec 31 04:29:27 1992  Ken Raeburn  (raeburn@kr-pc.cygnus.com)

 729         * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
 730         (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
 731         (segment_name) If BFD_ASSEMBLER, look up BFD section name;
 732         otherwise, use seg_name array.
 733         (seg_name): Declare only if not BFD_ASSEMBLER.
 734         (section_alignment): Declare only if not BFD_ASSEMBLER.
 735         (big_section, reg_section, pass1_section, diff_section,
 736         absent_section, text_section, data_section, bss_section): If
 737         BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,

 739         (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
 740         if these are used or defined, if BFD_ASSEMBLER.

 742         subseg_new split into two functions.
 743         (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
 744
 745         * as.h (volatile): Don't define if already defined.
 746         (had_errors, had_warnings): Provide prototypes for ANSI C even if
 747         NO_STDARG.
 748         (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
 749         declare with format attribute for -Wformat checking.
 750
 751 Wed Dec 30 10:18:57 1992  Ian Lance Taylor  (ian@cygnus.com)
 752
 753         * app.c, config/tc-*.c: Don't include read.h, since it is already
 754         included by as.h.
 755
 756         * These are based on patches from Minh Tran-le
 757         <mtranle@paris.intellicorp.com>.
 758         * configure.in (i[34]86-ibm-aix*): Accept i486 for host.  Use
 759         obj_format coffbfd and gas_target i386coff for target.
 760         (i[34]86-*-isc*): New host (uses sysv).
 761         * config/i386aix.mt: Removed (no longer used).
 762         * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
 763         (MINUS_G): Removed.
 764         (LDFLAGS): Added, defined as -shlib.
 765         * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
 766         * config/te-sco386.h (LOCAL_LABEL): Don't define.
 767         (DOT_LABEL_PREFIX): Define.
 768         * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
 769         name rather than L0\001.
 770         * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
 771         local_bss_counter.
 772         * symbols.c, symbols.h (local_bss_counter): Removed.
 773         * write.c (write_object_file): bss no longer uses
 774         local_bss_counter.  Pass correct data and bss size to
 775         VMS_write_object_file.
 776         * config/obj-vms.c (VMS_write_object_file): Accept bss size as
 777         argument, rather than using local_bss_counter.

 781         (size_section): Restored sanity check.
 782         (do_relocs_for): Base section address on s_paddr rather than
 783         computing it.  Adjust a29k R_IHIHALF special case to account for
 784         section paddr (used to require paddr to be zero).  If there are no
 785         reclos, set s_relptr to 0.  Set relocation size in object_headers.
 786         (fill_section): Always set s_vaddr here, removing
 787         ZERO_BASED_SEGMENTS case.  Force s_scnptr for bss to 0.  Don't set
 788         NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
 789         Set STYP_INFO for .comment.
 790         (coff_header_append): Use object headers and H_{SET,GET}_* macros.
 791         Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

 794         (do_linenos_for): Set lineno size in object_headers.
 795         (write_object_file): Use H_{SET,GET}_* macros.  Don't bother to
 796         set s_vaddr here.  If string_byte_count remains 4, set it back to
 797         0, and only write strings out if there are some.  Call
 798         fill_section before do_relocs_for and do_linenos_for.
 799         (obj_coff_section): Handle optional quoted second argument giving
 800         section characteristics.
 801         (obj_coff_bss): Added to handle .bss.
 802         (obj_coff_ident): Added to handle .ident (puts string in .comment
 803         section).
 804         (obj_coff_lcomm): Put common symbols in .bss, not .data.
 805         (fixup_mdeps): Change to segment.  Call frag_wane after
 806         md_convert_frag.
 807         (fixup_segment): Explicitly check S_IS_COMMON before making 386
 808         adjustment (already happened only for common symbols, but this is
 809         clearer).
 810         * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
 811         * config/tc-i386.c (s_bss): Don't use if I386COFF.
 812         (md_pseudo_table): Ignore .optim and .noopt.
 813         (tc_coff_sizemachdep): New function.
 814         * config/tc-i386.h (REVERSE_SORT_RELOCS): Undef, for SVR3
 815         compatibility.
 816         (LOCAL_LABEL): Removed definition.
 817         (DOT_LABEL_PREFIX): Defined.

 823         (symbol_chars): Now const.
 824
 825         * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
 826         and "0b".  If LOCAL_LABELS_DOLLAR, check for "0$".
 827
 828         * config/obj-coff.h: Don't use #elif.
 829
 830         * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
 831         have it.  (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
 832
 833 Wed Dec 16 12:12:33 1992  Ian Lance Taylor  (ian@cygnus.com)

 848
 849 Sat Dec 12 15:26:34 1992  Ian Lance Taylor  (ian@cygnus.com)
 850
 851         * listing.c: Call xmalloc, not malloc; don't declare malloc.
 852
 853         * Changes to support SCO 3.2v4:
 854         * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
 855         SEG_BSS, fill with NOP_OPCODE.

 857         * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
 858         using ZERO_BASED_SEGMENTS.
 859         (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
 860         never set segment address for SEG_E2 (.bss) and don't write out
 861         SEG_E2 contents.  Set .init and .fini sections to STYP_TEXT.
 862         (obj_coff_endef): Don't merge labels or symbols awaiting forward
 863         definitions, and don't merge tags with non-tags.  Check for .bf
 864         rather than just checking whether the second character is b and
 865         the third character is f.
 866         (obj_coff_val): gcc can generate values which we don't handle
 867         correctly; discard information for now, since it only affects the
 868         debugging information.
 869         (tag_find_or_name): Don't insert tags in the symbol table.
 870         (yank_symbols): Don't merge labels.
 871         (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
 872         already defined.  Fill subsegments with NOP_OPCODE, not 0.  Don't
 873         set segment address if ZERO_BASED_SEGMENTS.
 874         (obj_coff_section): Accept and ignore a trailing quoted string, as
 875         used in AT&T i386 syntax.
 876         (fixup_segment): Take segment as argument.  On the i386, adjust PC
 877         relative addends by the segment vaddr.
 878         * tc-i386.h: Define SUB_SEGMENT_ALIGN.
 879         * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
 880         * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

 897
 898         * Makefile.in (as.new): Don't bother saving as.old.
 899
 900         * write.c: Conditionalize on OBJ_VMS, not VMS.
 901         (magic_number_for_object_file): Don't define if OBJ_VMS.
 902
 903         * config/obj-vms.c: Changes for traditional C.

1009         * all files: Whitespace changes for GNU indentation style, done by
1010         GNU `indent'.  Some cleanup still needed, especially of comments.
1011
1012         * configure.in: No te-386bsd.h file exists; don't try to use it.
1013
1014         * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
1015
1016         * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
1017         could be doing emulation.
1018
1019 Thu Nov 19 11:47:19 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
1020
1021         z8000 documentation

1032         line_comment_chars, and line_separator_chars.
1033         read.c, app.c: removed definitions of comment_chars,
1034         line_comment_chars, and line_separator_chars.
1035
1036         * tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
1037         still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
1038         the register name.
1039         (insert_reg): put REGISTER_PREFIX before register names before
1040         putting them in the symbol table.
1041         * tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not
1042         M68KCOFF.
1043
1044         * obj-coffbfd.c (fill_section): set STYP_NOLOAD bit for .bss
1045         section.
1046
1047         * atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
1048         comment_chars, line_comment_chars and line_seperator_chars
1049         consistently const, and always initialized them.  Included read.h.
1050
1051 Thu Nov  5 17:55:41 1992  Jim Wilson  (wilson@sphagnum.cygnus.com)
1052
1053         * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
1054         constant will not fit in an immediate field.
1055         (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
1056
1057 Wed Nov  4 07:50:46 1992  Ken Raeburn  (raeburn@cygnus.com)
1058
1059         * obj-coff.c (callj_table): Delete global variable.
1060         (obj_emit_relocations): Define it locally here, and only if
1061         TC_I960 is defined.
1062
1063         * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.
1064         (m68k_ip): Don't warn about bignum used as float bit-pattern.
1065
1066         * obj-coff.c: Replaced ANSI and non-ANSI function declarations
1067         with a single set using PARAMS macro.
1068
1069         * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length
1070         of 2.
1071
1072         * tc-i960.c: Missed a couple of 0->NO_RELOC conversions.
1073
1074         * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
1075         so widening works consistently.
1076
1077 Wed Oct 28 08:52:34 1992  Ken Raeburn  (raeburn@cygnus.com)
1078
1079         * version.c: Put conditional "const" before version_string, not
1080         before dummy function for VMS.  Now version 1.91.03.
1081
1082         * app.c (do_scrub_next_char): Need double-\ before `000' to show
1083         printed rep of null character.
1084
1085 Fri Oct 23 14:40:38 1992  Ian Lance Taylor  (ian@cygnus.com)
1086
1087         * obj-coffbfd.c (write_object_file): check return value of
1088         bfd_close_all_done.
1089
1090 Tue Oct 20 12:18:08 1992  Ian Lance Taylor  (ian@cygnus.com)
1091
1092         * Support for i386-sysv.
1093         obj-coffbfd.c (do_relocs_for, write_object_file): set segment
1094         addresses to reasonable sizes.  New define ZERO_BASED_SEGMENTS can
1095         be used to set them all to zero as was done before.
1096         (fill_section): segment addresses now set in write_object_file.
1097         (fill_section): Don't set STYP_NOLOAD for .bss section.
1098         (fixup_segment): 386 uses strange common symbol format.
1099         tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
1100         compatibility with SVR3.2 linker.
1101         * configure.in: i386-sysv and i386-sco use coffbfd.
1102
1103         * app.c (do_scrub_next_char): discard whitespace after a label.
1104

1108         hosts, use the sysv configuration for solaris2
1109
1110 Mon Oct  5 09:28:57 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
1111
1112          fix i960+non-bfd coff bit rot.
1113         * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
1114         support for C source listings. (obj_coff_endef): look in the right
1115         part of the symbol for the symbol name
1116
1117         * tc-m68k.c (get_num): make it work for all segments, not just the
1118         first three.
1119
1120 Mon Oct  5 03:30:36 1992  Mark Eichin  (eichin at tweedledumber.cygnus.com)
1121
1122         * configure.in: recognize i386-*-bsd emulation.
1123

1130         * obj-coffbfd.c (write_object_file): don't fixup for the z8k
1131         * tc-z8k.c: lots of bug fixes

1133 Tue Sep 29 10:51:55 1992  Ian Lance Taylor  (ian@cygnus.com)
1134
1135         * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
1136         #elif, since it is not supported by old compilers.
1137         ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
1138         couple of expressions in tc-m68k.c.
1139
1140 Mon Sep 28 21:18:24 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
1141
1142         * read.c (cons): If NO_RELOC is defined, use it.
1143
1144         * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
1145
1146 Fri Sep 25 18:18:52 1992  Ian Lance Taylor  (ian@cygnus.com)
1147
1148         * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
1149         local labels to start with a .) and set REGISTER_PREFIX to %.
1150         tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
1151
1152 Fri Sep 25 17:53:43 1992  John Gilmore  (gnu@cygnus.com)
1153
1154         * messages.c:  Comment changes.
1155
1156 Fri Sep 25 14:12:58 1992  Ken Raeburn  (raeburn@kyriath.cygnus.com)
1157
1158         * as.h: Test if __STDC__ is defined only, don't test its value.
1159         * messages.c: If __STDC__ is not defined, define NO_STDARG.
1160
1161 Thu Sep 24 12:42:32 1992  Brendan Kehoe  (brendan@rtl.cygnus.com)
1162
1163         * listing.c (debugging_pseudo): Add stabs and stabn as things to
1164         ignore.
1165
1166 Tue Sep 22 13:02:07 1992  Sean Eric Fagan  (sef@cygnus.com)
1167
1168         * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
1169         sections starting from zero, rather than making them consecutive.
1170         This makes subsequent reloc calculations easier, esp if the object
1171         format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
1172         allocate lcomm in .data rather than in .bss.  It seems that some
1173         tools can't cope with a non-zero sized bss before linkage.
1174
1175 Tue Sep 22 15:10:51 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
1176
1177         * tc-m68k.c: Replace "enum m68k_architecture" with "int"
1178         throughout.  That enum no longer means what we thought it meant.
1179
1180         * tc-m68k.c (md_assemble, md_parse_option): Handle new
1181         "-mno-688[58]1" options.
1182
1183         * tc-m68k.c: Added CPU32 support.

1185 Fri Sep 18 08:02:18 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
1186
1187         * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
1188
1189 Tue Sep 15 17:25:05 1992  Jim Wilson  (wilson@sphagnum.cygnus.com)
1190
1191         * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
1192         Change LIBDEPS dependence to LIBS.
1193
1194 Tue Sep 15 15:32:02 1992  Ian Lance Taylor  (ian@cygnus.com)
1195
1196         * Makefile.in (install): if $(tooldir) exists, install as in
1197         $(tooldir)/bin.
1198
1199 Sun Sep 13 20:30:10 1992  Ian Lance Taylor  (ian@cygnus.com)
1200
1201         * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
1202         .word is < -32768 or > 32767.  The -J flag causes the error to be
1203         ignored.  This is to catch over-sized switches generated by gcc on
1204         systems which don't support the broken .word hack.
1205         as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
1206         write.c (fixup_segment): check for signed .word overflow if
1207         WARN_SIGNED_OVERFLOW_WORD.
1208
1209         * write.c (fixup_segment): fixed missing parens in expression
1210         checking for byte or word overflow.
1211
1212         * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
1213         obj-coffbfd.c (fixup_segment): check for signed .word overflow if
1214         WARN_SIGNED_OVERFLOW_WORD.
1215
1216         * obj-coffbfd.c (fixup_segment): fixed missing parens in
1217         expression checking for byte or word overflow.
1218
1219 Fri Sep 11 10:21:04 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
1220
1221         Support for i386 coff
1222         * obj-coffbfd.h : added stuff
1223         * tc-i386.c (tc_coff_fix2rtype): new function
1224         * tc-i386.h : new coff defines
1225
1226 Thu Sep 10 09:23:15 1992  Ian Lance Taylor  (ian@cygnus.com)
1227
1228         * input-scrub.c (input_scrub_push): call input_file_begin, not
1229         input_scrub_begin.
1230         messages.c (as_perror): print ": " between the passed in error and
1231         the strerror, like perror does.
1232
1233 Wed Sep  9 11:06:25 1992  Ian Lance Taylor  (ian@cygnus.com)
1234
1235         * Makefile.in: use gas_target instead of modifying target_cpu.
1236         From Steve Chamberlain:
1237         Makefile.in: Handle m68*-*-coff*.
1238         read.c, read.h: add mult argument to s_space
1239
1240         * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
1241          Motorola and MIT syntax; gas can now assemble either type of
1242          file.
1243         tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
1244         From Steve Chamberlain:
1245         m68kcoff.mt: for m68k COFF.
1246         obj-coffbfd.c: (fixup_mdeps) added
1247          (size_section) removed bad sanity check
1248          (fill_section) added rs_machine_dependent case
1249          (write_object_file) call fixup_mdeps
1250          (fixup_segment) set fx_subsy to 0.
1251         obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
1252          handle m68k.
1253         tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
1254          pseudo ops.
1255
1256 Tue Sep  8 17:10:58 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)

1262         * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
1263         including zero are accepted, pass +0.0.
1264

1280         tc-i960.c (md_ri_to_chars): Always output bout object file in
1281         little endian byte order (used to use endianness of host).
1282
1283 Tue Aug 25 15:50:48 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
1284
1285         * config/tc-m68k.c (init_table): Now const.  Always include 68851
1286         data, so that "bc" is available to 68040 cache instructions.
1287         Added "tt0", "tt1", and 68ec030 variants.
1288         (md_assemble): Complain if 68000 (only) and 68881 are specified.
1289         (enum _register): Added TT0, TT1.
1290         (m68k_ip, cases '3' and 't'): Handle new operand type codes.  Pass
1291         line number correctly in "internal error" messages.  Don't print
1292         architecture-mismatch message for operand errors.
1293
1294         From Colin Smith (colin@wrs.com):
1295         * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
1296         than install_operand.
1297

1299
1300         * listing.c (buffer_line): rewind to the start of include
1301         files, they might be included twice.

1304
1305 Mon Aug 24 12:45:43 1992  Ian Lance Taylor  (ian@cygnus.com)
1306
1307         * Makefile.in: defined TARGET_CPU for C code so that it can choose
1308         one element of a family.
1309
1310         * tc-m68k.c: use TARGET_CPU to choose default cpu type.
1311
1312         * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
1313         so that we can assemble hand-written libgcc code.
1314
1315 Fri Aug 21 14:38:44 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
1316
1317         * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
1318         has already been formatted (but may still contain %-characters).
1319         (as_bad): Likewise.
1320
1321 Wed Aug 19 11:20:59 1992  Ian Lance Taylor  (ian@cygnus.com)
1322
1323         * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
1324         written with indirection on the last two operands, which can be
1325         either data or address registers.  Added a new operand type 'r'
1326         which accepts either register type.  Added '(' to notend stuff in
1327         tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
1328

1685         * as.c: fix typo recently introduced.
1686         * as.h : Don't include aout/reloc.h - it's not right for COFF!
1687         * expr.c: Much rewriting, to accomodate MRI syntax for
1688         expressions. Also easier to read now.
1689         * listing.c: Put back defuns
1690         * read.c: modified to accept MRI syntax, put back listing pseudo
1691         ops so that an assembler built with NO_LISTING ignores list ops
1692         rather than pukes.
1693         * write.c, write.h: fixs - only keep a reloc type in a fix if the target
1694         machine is a SPARC or a 29K.
1695         * config/obj-aout.c: added s_sect pseudo op
1696         * config/obj-coffbfd.c: lints, set the filehdr flags right and
1697         fill in the timestamp.
1698         * config/obj-coffbfd.h: Since we don't include aout/reloc.h
1699         anymore, define all the relocs which the tc-<x> bit will use so we
1700         can translate from them to the coff types.
1701         * config/tc-a29k.c: reloc_type isn't ane enum any more
1702         * config/tc-m68k.c: Added NO_RELOC definition.

1705
1706         * Makefile.in: put header files before C source for TAGS; remove
1707           references to non-existent syscalls.h.
1708
1709         * read.c, write.c subsegs.c: back out the .bss changes.
1710
1711         * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
1712
1713         * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
1714
1715         * a.out.h: removed.

1718
1719         * symbols.c (local_label_name): symbols now start with ^A.
1720
1721         * read.c, subsegs.c, write.c obj-coff.c: added handling of
1722           `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
1723           generate these sections.  .align: will use NOP_OPCODE or 0
1724           for padding. This is just for being nice to the
1725           disassembler.
1726
1727         * expr.c (operand): changed to generate local label "\001L0"
1728           starting with a ^A so that it is recognized as a local label.
1729
1730         * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
1731
1732         * tc-i386.c: tc-i386.c: added handling of the following opcodes:
1733           i/o opcodes - inb, inw, outb and outw.  string manipulation with
1734           att syntax - scmp, slod, smov, ssca, ssto.
1735
1736         * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
1737           to just after .file .
1738
1739           In obj_crawl_symbol_chain() where it tries to put the external
1740           symbols apart, with the condition:
1741             (!S_IS_DEFINED(symbolP) &&
1742              !S_IS_DEBUG(symbolP) &&
1743              !SF_GET_STATICS(symbolP))
1744           it was moving too many symbols out. So I switch it back to the
1745           condition:
1746             (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
1747
1748           In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
1749           so that we don't use the F_RELFLG which make the linker complain
1750           that somebody has stripped the relocation info.
1751
1752           Also, the AIX ld program require that the relocation table
1753           is sorted by r_vaddr like the standard ATT assembler does.
1754
1755           [he also changed the sizeof(struct ...)'s into the coff
1756           style FOOSZ macros.  I'm not sure this is right, but I can't
1757           remember why.  xoxorich.]

1760
1761         * Makefile.in, configure.in, doc: use the doc.  Build it, install
1762           it, clean it, etc.
1763
1764 Tue Feb 18 02:21:25 1992  K. Richard Pixley  (rich at cygnus.com)
1765
1766         * read.c: white space and comments only.
1767
1768         * configure.in: use the new atof-ns32.c for ns32k.
1769
1770         * write.c: comment change only.
1771
1772         * tc-m88k.[hc]: pulled in from hack's unfinished work.  These
1773           aren't yet integrated.
1774
1775         * tc-i860.[hc]: blew off the dust.  Something must still be done
1776           about conflicting relocation types.
1777
1778         * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
1779           real thing.
1780
1781         * tc-i960.c, tc-sparc.c: white space and comments only.
1782
1783         * tc-a29k.h: delete duplicate macro definition.
1784
1785         * new file atof-ns32k.c copied from hack's last unreleased gas.

1788
1789         * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
1790           rather than abort.
1791
1792         * nearly everything.  flush ChangeLog, package as gas-1.92.1.
1793           ChangeLog's prior to this are sketchy at best.  I have logs.
1794           They just aren't ChangeLogs.
