   3         * subsegs.c (subseg_new): Set output_section of new section.
   4         * as.c (perform_an_assemly_pass): Don't set output_section here.
   5         * expr.c (expr_part, expr): Turn off section assertions for ECOFF,
   6         since it has additional sections.
   7         * read.c (s_lcomm): For MIPS ECOFF, put small objects in .sbss,
   8         not bss_section.
   9         * config/obj-ecoff.h (TARGET_SYMBOL_FIELDS): Added
  10         ecoff_undefined field.
  11         * config/obj-ecoff.c (obj_symbol_new_hook): Initialize
  12         ecoff_undefined field.
  13         (add_file): If using stabs, just output a stabs symbol rather than
  14         creating a new fdr.
  15         (obj_ecoff_begin, obj_ecoff_bend): Ignore line number by reading
  16         it with get_absolute_expression, rather than skipping it by hand.
  17         (obj_ecoff_loc): If using stabs, just output a stabs symbol rather
  18         than ECOFF line number information.
  19         (obj_ecoff_stab): Accept non-zero values for stabs line number.
  20         (ecoff_build_symbols): Set ifilesym correctly.  Set storage class
  21         to small, undefined and/or readonly sections if appropriate.
  22         Don't output symbol names containing \001 characters.
  23         (ecoff_frob_file): Make sure at least one fdr is output.

  26         (md_assemble): Set gp size of output BFD.
  27         (gp_reference): New function; returns 1 if expression can be
  28         accesssed via gp.  Always returns 0 if not using ECOFF.

  30         possible.
  31         (macro): Generate sequences using gp if possible.
  32         (md_parse_option): Ignore -EL and -EB.  Parse -G.

  39         * output-file.c (output_file_create): Don't call as_perror for
  40         filename rejected by application.
  41
  42         * as.c (main) [BFD_ASSEMBLER]: If errors occur, close and unlink
  43         the output file.
  44
  45         * doc/as.texinfo: Don't use @value in node names for the moment;
  46         references don't appear to work right.
  47
  48         * as.h (const, volatile): Put these definitions back, and use
  49         them.
  50
  51         * doc/as.texinfo: First pass at using new texinfo features --
  52         variables, conditional tests.  Far from complete.
  53
  54 Mon Mar 29 16:05:40 1993  Ken Raeburn  (raeburn@cambridge.cygnus.com)
  55
  56         * read.c: Temporary hack to handle some 64-bit constants.  This
  57         should be redone later.
  58         (target_big_endian): Declare.
  59         (big_cons): If it's set, reverse order of bytes being copied.
  60         * config/tc-sparc.c (md_begin): Set target_big_endian.

  65         forward pointers properly.
  66
  67 Mon Mar 29 13:47:33 1993  Steve Chamberlain  (sac@thepub.cygnus.com)
  68
  69         * config/obj-coffbfd.c (do_relocs_for): Fix bug where nrelocs
  70         wasn't being stored into scnhdr.

  74         if a label has been seen.
  75
  76 Mon Mar 29 12:56:56 1993  Ian Lance Taylor  (ian@cygnus.com)
  77
  78         * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
  79         the bottom (make expands variables in dependencies when the
  80         dependencies are read, not when they are used).
  81
  82         * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
  83         a29k .bss section; the mondfe program doesn't like it.
  84
  85 Sun Mar 28 08:12:53 1993  Ken Raeburn  (raeburn@kr-pc.cygnus.com)
  86
  87         * config/tc-m68k.c: Use PARAMS macro, and use CONST instead of
  88         const.
  89         (current_architecture): Don't need initializer.
  90
  91 Fri Mar 26 08:12:48 1993  Ken Raeburn  (raeburn@cambridge.cygnus.com)
  92
  93         * doc/none.m4: Define Z8000.
  94         * doc/Makefile.in (as-*.texinfo): Refer to $(srcdir).  Remove the
  95         texinfo file before recreating it.
  96         (TEXI2DVI): Need to set TEXINPUTS if "make as.dvi" is to work in
  97         this directory.
  98         (srcdir): Delete second, bogus definition.
  99         (as.info): Look for as-*.texinfo in current directory rather than
 100         in $(srcdir).
 101         (as.dvi): Ditto.
 102         (dvi): New rule.
 103         * doc/configure.in: Create links to all as-*.texinfo files in the

 106         * configure.in (per-host):  Accept MIPS host with BSD version
 107         number.
 108         (per-target): Classify i486 as i386.  Use generic cpu_type instead
 109         of target_cpu in selecting format etc.
 110
 111         * app.c (do_scrub_next_char): Use .appfile, not .app-file.
 112         * read.c (potable): Change .app-file to .appfile.
 113
 114         * config/ho-decstatn.h: Renamed from ho-decstation.h.
 115         * configure.in: Adjusted.
 116
 117         * config/obj-bfd-sunos.*: Unused; deleted.
 118
 119         * Makefile.in (version.c, vers-stamp): Deleted.
 120         (config.h): Define GAS_VERSION.
 121         * as.c (version_string): Deleted declaration.
 122         (main): Look for GAS_VERSION instead.
 123
 124         * doc/as.texinfo: Updated description of -a* (listing) options,
 125         and describe how to pass them through from gcc.
 126
 127         * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
 128         process relocs if there aren't any relocs to process.  Avoids
 129         malloc/free bug on SCO too.
 130
 131         * as.h: Move local include files below system include files, to
 132         avoid some redefinition complaints on some systems.
 133         (const, volatile): Don't need these conditionally defined if we
 134         use CONST and VOLATILE from ansidecl.h.
 135         (seg_name): Use CONST, not const.
 136
 137 Fri Mar 26 10:22:04 1993  Ian Lance Taylor  (ian@cygnus.com)
 138
 139         * config/tc-mips.c: Reindented to GNU standards.
 140
 141 Thu Mar 25 08:59:14 1993  Ian Lance Taylor  (ian@cygnus.com)
 142
 143         * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
 144         (fixup_segment): Add a29k special case; the linker is not prepared
 145         to see a segment offset here.
 146
 147         * app.c (do_scrub_next_char): Added new state, 10, modifying state
 148         9 to only keep a space in between identifier characters.
 149
 150 Wed Mar 24 02:16:22 1993  david d `zoo' zuhn  (zoo at poseidon.cygnus.com)
 151
 152         * Makefile.in: add dvi target; as-$(config).texinfo might live in
 153         srcdir, might be in objdir.
 154
 155         * doc/Makefile.in: dvi depends on as.dvi
 156
 157 Mon Mar 22 23:59:13 1993  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)
 158
 159         * Makefile.in: add installcheck target

 164
 165 Sat Mar 20 12:50:51 1993  Ken Raeburn  (raeburn@urth.cygnus.com)
 166
 167         * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
 168         bignums, but don't emit error message.
 169
 170 Fri Mar 19 21:02:19 1993  Jim Wilson  (wilson@sphagnum.cygnus.com)
 171
 172         * Makefile.in (targ-cpu.o): Depend on config.h.
 173
 174 Wed Mar 17 16:44:06 1993  Ian Lance Taylor  (ian@cygnus.com)
 175
 176         * app.c (do_scrub_next_char): Added new state, 9, to avoid
 177         dropping a space immediately following an identifier.
 178         * expr.c, write.c: Rewrote assert expressions to not use multiple
 179         lines; I don't think that can be done portably.
 180         * config/tc-mips.c (macro): Use $AT if target register is zero in
 181         load instruction, which it can be for a floating point load.
 182

 184
 185         * write.c (write_contents): Compute the relocs before writing out
 186         the section contents.
 187         * config/obj-ecoff.h, config/obj-ecoff.c: Numerous changes to get
 188         symbol table and values right.
 189         * config/tc-mips.h (LOCAL_LABEL): If OBJ_ECOFF, any label starting
 190         with $L is local.
 191         * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
 192         by the section vma.
 193
 194         * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
 195         z8k-opc.h, not z8k.h.
 196
 197         * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
 198         symbol.

 201
 202         * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
 203
 204 Fri Mar 12 12:00:07 1993  Ian Lance Taylor  (ian@cygnus.com)
 205
 206         * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
 207         to be on a single line.
 208
 209 Thu Mar 11 17:56:22 1993  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 210
 211         * Makefile.in (config.h): Create file, writing out definitions of
 212         target cpu, alias, and canonical name.
 213         (ALL_CFLAGS): No longer define TARGET_CPU.
 214
 215         * Makefile.in (check): Print a message, instead of quitting
 216         silently.
 217
 218         * as.c (main): Don't catch any signals, for now.
 219
 220         * version.c: Deleted.
 221         * Makefile.in: Generate it, putting in only the version number
 222         itself.
 223         (VERSION): New variable.
 224         * as.c: Include config.h.
 225         (main): Reformatted version string.  Include target alias.  Don't
 226         print if not requested (i.e., unknown -v argument).
 227
 228         * as.c (stralloc): Deleted.
 229         (main): Call strdup instead.

 238
 239         * as.c (EXIT_SUCCESS, EXIT_FAILURE): Define to normal values if
 240         not already defined.
 241         (main, got_sig): Use them.

 246
 247         * config/obj-ecoff.c, config/obj-ecoff.h: Preliminary ECOFF
 248         support.
 249
 250         * config/tc-mips.h (TARGET_FORMAT): Define based on OBJ_AOUT vs.
 251         OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
 252         (struct loc, struct proc, struct file): Moved to tc-mips.c within
 253         #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
 254         * config/tc-mips.c: Rearranged for ECOFF support.  Added
 255         prototypes for all static functions.  Moved existing minimal
 256         debugging format support info #ifndef OBJ_ECOFF blocks.
 257         (macro_build_lui): Eliminated sign_extend argument, because ECOFF
 258         does not support a non sign extended high 16 bits reloc.  Adjusted
 259         all callers accordingly.
 260         (tc_get_register): Renamed from get_register, and made non-static.
 261
 262         * config/mips-big.mt, config/mips-lit.mt: New files.  Define
 263         TARGET_BYTES_BIG_ENDIAN and TARGET_BYTES_LITTLE_ENDIAN,
 264         respectively.
 265         * configure.in (mips-*-bsd*): Use gas_target mips-lit.
 266         (mips-*-ultrix*, mips-*-irix*, mips-*-ecoff): New targets, using
 267         obj_format ecoff and gas_target mips-lit or mips-big.
 268
 269 Tue Mar  9 07:43:01 1993  Ken Raeburn  (raeburn@cygnus.com)
 270
 271         * version.c: Bump to version 2.0.1.
 272
 273 Tue Mar  9 07:40:06 1993  Ian Lance Taylor  (ian@cygnus.com)
 274
 275         * write.c (chain_frchains_together): Check that seg_info (section)
 276         is not NULL.
 277         (write_object_file): Call obj_frob_file after setting the symbols,
 278         not before.

 286         * config/tc-i386.h (TC_COUNT_RELOC): Look for fx_addsy only.
 287
 288 Fri Mar  5 09:05:55 1993  Ian Lance Taylor  (ian@cygnus.com)
 289
 290         * read.h: Define stringer here.
 291         read.c, config/obj-ieee.c, config/obj-tcm88k.c: Not any of these
 292         places.
 293
 294 Thu Mar  4 11:52:23 1993  Steve Chamberlain  (sac@thepub.cygnus.com)
 295
 296         * read.c (s_space): Multiply repeat count by mult, not fill.
 297
 298 Thu Mar  4 05:20:42 1993  Ken Raeburn  (raeburn@cygnus.com)
 299
 300         * read.c: Include ctype.h.

 302 Wed Mar  3 10:41:46 1993  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 303
 304         Patches from Eric Youngdale:
 305         * make-gas.com: Find obstack.obj if it's not in the current
 306         directory.
 307         * read.c (s_ignore): Don't declare is_end_of_line.  It's
 308         redundant, and triggers a VMS gcc compiler bug.
 309
 310         * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
 311         current segment as an argument.  (Ignored in all cases but VMS.)
 312         All callers and definitions changed.
 313
 314 Tue Mar  2 11:56:19 1993  Ian Lance Taylor  (ian@cygnus.com)
 315
 316         * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING
 317         case compile again.
 318
 319 Tue Mar  2 08:53:34 1993  Ken Raeburn  (raeburn@cygnus.com)
 320
 321         * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,
 322         so "~0x80" won't be rejected.
 323
 324         * config/obj-elf.c: No longer include elf/reloc.h.
 325         (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
 326         (obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out
 327         routines.
 328         (obj_elf_xstab): New routine.
 329         (obj_elf_set_size): Call as_warn, not fprintf.  Pass desired
 330         argument to s_ignore.  Put "#if 0" around unused code.
 331         (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
 332         Call elf_xstabs for .stabs and .xstabs operators.
 333
 334         * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
 335
 336         * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
 337         present.
 338
 339         * configure.in: mips-bsd configuration was missing format spec.
 340         Should use aout.
 341
 342         * Makefile.in (Makefile): Depends on configure.in.
 343
 344         * config/tc-mips.c (append_insn): Don't check for alignment of
 345         frag in memory; alignment of instructions in section is a separate
 346         matter.
 347
 348         * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
 349         C availability.

 624
 625         * expr.c (operand): If character other than comma or newline is a
 626         logical end-of-line character, use the newline case.

 628         (operand): Set X_add_number field for floating-point numbers.
 629         (operand): Treat zero byte as end-of-operand.
 630
 631         * configure.in (per-target): Look for with_bfd_assembler option.
 632         For now, only accept "no", until the merge is done.
 633
 634         Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
 635         * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
 636           config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
 637         * read.c: Finish conversion to S_* macros in the VMS only
 638           parts of the program. Add "const" modifier to hex_value.
 639         * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
 640           "ifdef OBJ_VMS".
 641         * expr.c: Add "const" modifier to hex_value.
 642         * symbols.c: Finish conversion to S_* macros in the VMS only
 643           parts of the program.  Add "const" modifier to
 644           md_[long,short]_jump_size. Remove declaration of const_flag
 645           (which will be declared in obj-vms.h).
 646         * write.c: Add "const" modifier to md_[long,short]_jump_size.
 647           Fix arguments to VMS_write_object_file.
 648         * config-gas.com: New file.  Script for VMS systems to set up the
 649           configuration to build gas for VMS, and create config.status.
 650         * make-gas.com: Redone to work with new scheme.
 651         * obj-vms.c: Patch to fix bug where we were not correctly parsing the
 652           stabs directives.
 653         * obj-vms.c:  Define macros COPY_LONG and COPY_SHORT which
 654           will swap bytes if needed on a big endian system.  Use throughout
 655           as needed.
 656         * obj-vms.c (obj_aout_stab):  Add code to generate listing file.
 657         * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
 658           types of malformed stabs.  Change parsing algorithm so that we are
 659           more certain of having all of the information that we need on hand.
 660         * obj-vms.c (final_forward_reference):  New function, used to help
 661           resolve the data types of as many struct elements as possible
 662           when some part of the struct is not fully defined by the compiler.
 663         * obj-vms.c (VMS_LSYM_Parse):  Correctly handle case of continuation
 664           stabs directives.
 665         * obj-vms.c (VMS_write_object_file): Define all vtable psects
 666           as symbols as well in the object file.  Look for external functions
 667           that start with "__vt.", and turn them into variables, since the
 668           g++ compiler is incapable of doing this.
 669         * tc-vax.c: Add '1' option for backward compatibility with older GCC
 670           versions.
 671         * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

 677
 678         * read.c (s_data): Always use "data_section", since it'll map to
 679         SEG_DATA or SEG_E1 if needed.
 680         (s_lcomm): Likewise with bss_section.
 681         (s_fill): Use memset, not bzero.

 699         * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
 700         (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
 701         (segment_name) If BFD_ASSEMBLER, look up BFD section name;
 702         otherwise, use seg_name array.
 703         (seg_name): Declare only if not BFD_ASSEMBLER.
 704         (section_alignment): Declare only if not BFD_ASSEMBLER.
 705         (big_section, reg_section, pass1_section, diff_section,
 706         absent_section, text_section, data_section, bss_section): If

 716         (had_errors, had_warnings): Provide prototypes for ANSI C even if
 717         NO_STDARG.
 718         (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
 719         declare with format attribute for -Wformat checking.
 720
 721 Wed Dec 30 10:18:57 1992  Ian Lance Taylor  (ian@cygnus.com)
 722
 723         * app.c, config/tc-*.c: Don't include read.h, since it is already
 724         included by as.h.
 725
 726         * These are based on patches from Minh Tran-le
 727         <mtranle@paris.intellicorp.com>.
 728         * configure.in (i[34]86-ibm-aix*): Accept i486 for host.  Use
 729         obj_format coffbfd and gas_target i386coff for target.
 730         (i[34]86-*-isc*): New host (uses sysv).
 731         * config/i386aix.mt: Removed (no longer used).
 732         * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
 733         (MINUS_G): Removed.
 734         (LDFLAGS): Added, defined as -shlib.
 735         * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
 736         * config/te-sco386.h (LOCAL_LABEL): Don't define.
 737         (DOT_LABEL_PREFIX): Define.
 738         * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
 739         name rather than L0\001.
 740         * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
 741         local_bss_counter.
 742         * symbols.c, symbols.h (local_bss_counter): Removed.
 743         * write.c (write_object_file): bss no longer uses
 744         local_bss_counter.  Pass correct data and bss size to
 745         VMS_write_object_file.
 746         * config/obj-vms.c (VMS_write_object_file): Accept bss size as

 751         (size_section): Restored sanity check.
 752         (do_relocs_for): Base section address on s_paddr rather than
 753         computing it.  Adjust a29k R_IHIHALF special case to account for
 754         section paddr (used to require paddr to be zero).  If there are no
 755         reclos, set s_relptr to 0.  Set relocation size in object_headers.
 756         (fill_section): Always set s_vaddr here, removing
 757         ZERO_BASED_SEGMENTS case.  Force s_scnptr for bss to 0.  Don't set
 758         NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
 759         Set STYP_INFO for .comment.
 760         (coff_header_append): Use object headers and H_{SET,GET}_* macros.
 761         Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

 764         (do_linenos_for): Set lineno size in object_headers.
 765         (write_object_file): Use H_{SET,GET}_* macros.  Don't bother to
 766         set s_vaddr here.  If string_byte_count remains 4, set it back to
 767         0, and only write strings out if there are some.  Call
 768         fill_section before do_relocs_for and do_linenos_for.
 769         (obj_coff_section): Handle optional quoted second argument giving
 770         section characteristics.
 771         (obj_coff_bss): Added to handle .bss.
 772         (obj_coff_ident): Added to handle .ident (puts string in .comment
 773         section).
 774         (obj_coff_lcomm): Put common symbols in .bss, not .data.
 775         (fixup_mdeps): Change to segment.  Call frag_wane after
 776         md_convert_frag.
 777         (fixup_segment): Explicitly check S_IS_COMMON before making 386
 778         adjustment (already happened only for common symbols, but this is
 779         clearer).
 780         * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
 781         * config/tc-i386.c (s_bss): Don't use if I386COFF.
 782         (md_pseudo_table): Ignore .optim and .noopt.
 783         (tc_coff_sizemachdep): New function.
 784         * config/tc-i386.h (REVERSE_SORT_RELOCS): Undef, for SVR3
 785         compatibility.
 786         (LOCAL_LABEL): Removed definition.
 787         (DOT_LABEL_PREFIX): Defined.

 793         (symbol_chars): Now const.
 794
 795         * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
 796         and "0b".  If LOCAL_LABELS_DOLLAR, check for "0$".
 797
 798         * config/obj-coff.h: Don't use #elif.
 799
 800         * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
 801         have it.  (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
 802
 803 Wed Dec 16 12:12:33 1992  Ian Lance Taylor  (ian@cygnus.com)

 820
 821         * listing.c: Call xmalloc, not malloc; don't declare malloc.
 822
 823         * Changes to support SCO 3.2v4:

 827         * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
 828         using ZERO_BASED_SEGMENTS.
 829         (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
 830         never set segment address for SEG_E2 (.bss) and don't write out
 831         SEG_E2 contents.  Set .init and .fini sections to STYP_TEXT.
 832         (obj_coff_endef): Don't merge labels or symbols awaiting forward
 833         definitions, and don't merge tags with non-tags.  Check for .bf
 834         rather than just checking whether the second character is b and
 835         the third character is f.
 836         (obj_coff_val): gcc can generate values which we don't handle
 837         correctly; discard information for now, since it only affects the
 838         debugging information.
 839         (tag_find_or_name): Don't insert tags in the symbol table.
 840         (yank_symbols): Don't merge labels.
 841         (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

 843         set segment address if ZERO_BASED_SEGMENTS.
 844         (obj_coff_section): Accept and ignore a trailing quoted string, as
 845         used in AT&T i386 syntax.
 846         (fixup_segment): Take segment as argument.  On the i386, adjust PC
 847         relative addends by the segment vaddr.
 848         * tc-i386.h: Define SUB_SEGMENT_ALIGN.
 849         * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
 850         * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

 871         (magic_number_for_object_file): Don't define if OBJ_VMS.
 872
 873         * config/obj-vms.c: Changes for traditional C.

1012         M68KCOFF.
1013
1014         * obj-coffbfd.c (fill_section): set STYP_NOLOAD bit for .bss
1015         section.
1016
1017         * atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
1018         comment_chars, line_comment_chars and line_seperator_chars
1019         consistently const, and always initialized them.  Included read.h.

1021 Thu Nov  5 17:55:41 1992  Jim Wilson  (wilson@sphagnum.cygnus.com)
1022
1023         * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
1024         constant will not fit in an immediate field.
1025         (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

1027 Wed Nov  4 07:50:46 1992  Ken Raeburn  (raeburn@cygnus.com)
1028
1029         * obj-coff.c (callj_table): Delete global variable.
1030         (obj_emit_relocations): Define it locally here, and only if
1031         TC_I960 is defined.
1032
1033         * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.
1034         (m68k_ip): Don't warn about bignum used as float bit-pattern.
1035
1036         * obj-coff.c: Replaced ANSI and non-ANSI function declarations
1037         with a single set using PARAMS macro.
1038
1039         * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length
1040         of 2.
1041
1042         * tc-i960.c: Missed a couple of 0->NO_RELOC conversions.
1043
1044         * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
1045         so widening works consistently.
1046
1047 Wed Oct 28 08:52:34 1992  Ken Raeburn  (raeburn@cygnus.com)
1048
1049         * version.c: Put conditional "const" before version_string, not
1050         before dummy function for VMS.  Now version 1.91.03.
1051
1052         * app.c (do_scrub_next_char): Need double-\ before `000' to show
1053         printed rep of null character.

1055 Fri Oct 23 14:40:38 1992  Ian Lance Taylor  (ian@cygnus.com)
1056
1057         * obj-coffbfd.c (write_object_file): check return value of
1058         bfd_close_all_done.
1059
1060 Tue Oct 20 12:18:08 1992  Ian Lance Taylor  (ian@cygnus.com)
1061
1062         * Support for i386-sysv.
1063         obj-coffbfd.c (do_relocs_for, write_object_file): set segment
1064         addresses to reasonable sizes.  New define ZERO_BASED_SEGMENTS can
1065         be used to set them all to zero as was done before.
1066         (fill_section): segment addresses now set in write_object_file.
1067         (fill_section): Don't set STYP_NOLOAD for .bss section.
1068         (fixup_segment): 386 uses strange common symbol format.
1069         tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
1070         compatibility with SVR3.2 linker.
1071         * configure.in: i386-sysv and i386-sco use coffbfd.
1072

1078         hosts, use the sysv configuration for solaris2
1079
1080 Mon Oct  5 09:28:57 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
1081
1082          fix i960+non-bfd coff bit rot.
1083         * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
1084         support for C source listings. (obj_coff_endef): look in the right
1085         part of the symbol for the symbol name
1086
1087         * tc-m68k.c (get_num): make it work for all segments, not just the
1088         first three.
1089
1090 Mon Oct  5 03:30:36 1992  Mark Eichin  (eichin at tweedledumber.cygnus.com)
1091

1103 Tue Sep 29 10:51:55 1992  Ian Lance Taylor  (ian@cygnus.com)
1104
1105         * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
1106         #elif, since it is not supported by old compilers.
1107         ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
1108         couple of expressions in tc-m68k.c.
1109
1110 Mon Sep 28 21:18:24 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
1111
1112         * read.c (cons): If NO_RELOC is defined, use it.
1113
1114         * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
1115
1116 Fri Sep 25 18:18:52 1992  Ian Lance Taylor  (ian@cygnus.com)
1117
1118         * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
1119         local labels to start with a .) and set REGISTER_PREFIX to %.
1120         tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
1121
1122 Fri Sep 25 17:53:43 1992  John Gilmore  (gnu@cygnus.com)

1125

1127
1128         * as.h: Test if __STDC__ is defined only, don't test its value.
1129         * messages.c: If __STDC__ is not defined, define NO_STDARG.
1130
1131 Thu Sep 24 12:42:32 1992  Brendan Kehoe  (brendan@rtl.cygnus.com)

1136 Tue Sep 22 13:02:07 1992  Sean Eric Fagan  (sef@cygnus.com)
1137
1138         * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
1139         sections starting from zero, rather than making them consecutive.
1140         This makes subsequent reloc calculations easier, esp if the object
1141         format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
1142         allocate lcomm in .data rather than in .bss.  It seems that some
1143         tools can't cope with a non-zero sized bss before linkage.
1144
1145 Tue Sep 22 15:10:51 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
1146
1147         * tc-m68k.c: Replace "enum m68k_architecture" with "int"
1148         throughout.  That enum no longer means what we thought it meant.
1149
1150         * tc-m68k.c (md_assemble, md_parse_option): Handle new
1151         "-mno-688[58]1" options.
1152
1153         * tc-m68k.c: Added CPU32 support.

1158
1159 Tue Sep 15 17:25:05 1992  Jim Wilson  (wilson@sphagnum.cygnus.com)
1160
1161         * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.

1165
1166         * Makefile.in (install): if $(tooldir) exists, install as in
1167         $(tooldir)/bin.
1168
1169 Sun Sep 13 20:30:10 1992  Ian Lance Taylor  (ian@cygnus.com)
1170
1171         * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
1172         .word is < -32768 or > 32767.  The -J flag causes the error to be
1173         ignored.  This is to catch over-sized switches generated by gcc on
1174         systems which don't support the broken .word hack.
1175         as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
1176         write.c (fixup_segment): check for signed .word overflow if
1177         WARN_SIGNED_OVERFLOW_WORD.
1178
1179         * write.c (fixup_segment): fixed missing parens in expression
1180         checking for byte or word overflow.
1181
1182         * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
1183         obj-coffbfd.c (fixup_segment): check for signed .word overflow if
1184         WARN_SIGNED_OVERFLOW_WORD.
1185
1186         * obj-coffbfd.c (fixup_segment): fixed missing parens in
1187         expression checking for byte or word overflow.
1188
1189 Fri Sep 11 10:21:04 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
1190

1197
1198         * input-scrub.c (input_scrub_push): call input_file_begin, not
1199         input_scrub_begin.
1200         messages.c (as_perror): print ": " between the passed in error and
1201         the strerror, like perror does.
1202
1203 Wed Sep  9 11:06:25 1992  Ian Lance Taylor  (ian@cygnus.com)
1204
1205         * Makefile.in: use gas_target instead of modifying target_cpu.
1206         From Steve Chamberlain:
1207         Makefile.in: Handle m68*-*-coff*.
1208         read.c, read.h: add mult argument to s_space
1209
1210         * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
1211          Motorola and MIT syntax; gas can now assemble either type of
1212          file.
1213         tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
1214         From Steve Chamberlain:
1215         m68kcoff.mt: for m68k COFF.
1216         obj-coffbfd.c: (fixup_mdeps) added
1217          (size_section) removed bad sanity check
1218          (fill_section) added rs_machine_dependent case
1219          (write_object_file) call fixup_mdeps
1220          (fixup_segment) set fx_subsy to 0.
1221         obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
1222          handle m68k.
1223         tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
1224          pseudo ops.
1225

1250         tc-i960.c (md_ri_to_chars): Always output bout object file in
1251         little endian byte order (used to use endianness of host).
1252
1253 Tue Aug 25 15:50:48 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
1254
1255         * config/tc-m68k.c (init_table): Now const.  Always include 68851
1256         data, so that "bc" is available to 68040 cache instructions.
1257         Added "tt0", "tt1", and 68ec030 variants.
1258         (md_assemble): Complain if 68000 (only) and 68881 are specified.
1259         (enum _register): Added TT0, TT1.
1260         (m68k_ip, cases '3' and 't'): Handle new operand type codes.  Pass
1261         line number correctly in "internal error" messages.  Don't print
1262         architecture-mismatch message for operand errors.
1263
1264         From Colin Smith (colin@wrs.com):
1265         * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

1276
1277         * Makefile.in: defined TARGET_CPU for C code so that it can choose
1278         one element of a family.

1280         * tc-m68k.c: use TARGET_CPU to choose default cpu type.
1281
1282         * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
1283         so that we can assemble hand-written libgcc code.
1284

1286
1287         * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
1288         has already been formatted (but may still contain %-characters).
1289         (as_bad): Likewise.
1290
1291 Wed Aug 19 11:20:59 1992  Ian Lance Taylor  (ian@cygnus.com)
1292
1293         * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
1294         written with indirection on the last two operands, which can be
1295         either data or address registers.  Added a new operand type 'r'
1296         which accepts either register type.  Added '(' to notend stuff in
1297         tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

1311         (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is

1314
1315         * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
1316         their not having symbols associated.
1317
1318         * tc-i960.c (norelax, instrument_branches): Default initializer is
1319         sufficient.
1320         (linkrelax): Delete variable definition.
1321         (mem_fmt): Call fix_new with NO_RELOC.
1322         (tc_bout_fix_to_chars): Handle alignment relocs.

1637
1638         * expr.c: If an expression is single comma, then return with
1639         SEG_ABSENT rather than an error - since the sparc front end does

1641
1642         * as.h: include bfd.h if using many sections

1658         expressions. Also easier to read now.
1659         * listing.c: Put back defuns
1660         * read.c: modified to accept MRI syntax, put back listing pseudo
1661         ops so that an assembler built with NO_LISTING ignores list ops
1662         rather than pukes.
1663         * write.c, write.h: fixs - only keep a reloc type in a fix if the target
1664         machine is a SPARC or a 29K.
1665         * config/obj-aout.c: added s_sect pseudo op
1666         * config/obj-coffbfd.c: lints, set the filehdr flags right and
1667         fill in the timestamp.
1668         * config/obj-coffbfd.h: Since we don't include aout/reloc.h
1669         anymore, define all the relocs which the tc-<x> bit will use so we
1670         can translate from them to the coff types.
1671         * config/tc-a29k.c: reloc_type isn't ane enum any more
1672         * config/tc-m68k.c: Added NO_RELOC definition.

1683         * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
1684
1685         * a.out.h: removed.

1688
1689         * symbols.c (local_label_name): symbols now start with ^A.
1690
1691         * read.c, subsegs.c, write.c obj-coff.c: added handling of
1692           `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
1693           generate these sections.  .align: will use NOP_OPCODE or 0
1694           for padding. This is just for being nice to the
1695           disassembler.
1696
1697         * expr.c (operand): changed to generate local label "\001L0"
1698           starting with a ^A so that it is recognized as a local label.
1699
1700         * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
1701
1702         * tc-i386.c: tc-i386.c: added handling of the following opcodes:
1703           i/o opcodes - inb, inw, outb and outw.  string manipulation with
1704           att syntax - scmp, slod, smov, ssca, ssto.
1705
1706         * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
1707           to just after .file .
1708
1709           In obj_crawl_symbol_chain() where it tries to put the external
1710           symbols apart, with the condition:
1711             (!S_IS_DEFINED(symbolP) &&
1712              !S_IS_DEBUG(symbolP) &&
1713              !SF_GET_STATICS(symbolP))
1714           it was moving too many symbols out. So I switch it back to the
1715           condition:
1716             (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
1717
1718           In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
1719           so that we don't use the F_RELFLG which make the linker complain
1720           that somebody has stripped the relocation info.
1721
1722           Also, the AIX ld program require that the relocation table
1723           is sorted by r_vaddr like the standard ATT assembler does.
1724
1725           [he also changed the sizeof(struct ...)'s into the coff
1726           style FOOSZ macros.  I'm not sure this is right, but I can't
1727           remember why.  xoxorich.]

1730
1731         * Makefile.in, configure.in, doc: use the doc.  Build it, install
1732           it, clean it, etc.
1733
1734 Tue Feb 18 02:21:25 1992  K. Richard Pixley  (rich at cygnus.com)
1735
1736         * read.c: white space and comments only.
1737
1738         * configure.in: use the new atof-ns32.c for ns32k.
1739
1740         * write.c: comment change only.
1741
1742         * tc-m88k.[hc]: pulled in from hack's unfinished work.  These
1743           aren't yet integrated.
1744
1745         * tc-i860.[hc]: blew off the dust.  Something must still be done
1746           about conflicting relocation types.
1747
1748         * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
1749           real thing.
1750
1751         * tc-i960.c, tc-sparc.c: white space and comments only.
1752
1753         * tc-a29k.h: delete duplicate macro definition.
1754
1755         * new file atof-ns32k.c copied from hack's last unreleased gas.

1758
1759         * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
1760           rather than abort.
1761
1762         * nearly everything.  flush ChangeLog, package as gas-1.92.1.
1763           ChangeLog's prior to this are sketchy at best.  I have logs.
1764           They just aren't ChangeLogs.
