   7
   8         * Makefile.in: add dvi target; as-$(config).texinfo might live in

  33         dropping a space immediately following an identifier.
  34         * expr.c, write.c: Rewrote assert expressions to not use multiple
  35         lines; I don't think that can be done portably.
  36         * config/tc-mips.c (macro): Use $AT if target register is zero in
  37         load instruction, which it can be for a floating point load.

  46         with $L is local.
  47         * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
  48         by the section vma.
  49
  50         * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is

  66
  67         * Makefile.in (config.h): Create file, writing out definitions of

  69         (ALL_CFLAGS): No longer define TARGET_CPU.
  70
  71         * Makefile.in (check): Print a message, instead of quitting
  72         silently.
  73
  74         * as.c (main): Don't catch any signals, for now.
  75
  76         * version.c: Deleted.

 107         OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
 108         (struct loc, struct proc, struct file): Moved to tc-mips.c within
 109         #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
 110         * config/tc-mips.c: Rearranged for ECOFF support.  Added
 111         prototypes for all static functions.  Moved existing minimal
 112         debugging format support info #ifndef OBJ_ECOFF blocks.
 113         (macro_build_lui): Eliminated sign_extend argument, because ECOFF
 114         does not support a non sign extended high 16 bits reloc.  Adjusted
 115         all callers accordingly.
 116         (tc_get_register): Renamed from get_register, and made non-static.
 117
 118         * config/mips-big.mt, config/mips-lit.mt: New files.  Define

 131         * write.c (chain_frchains_together): Check that seg_info (section)
 132         is not NULL.
 133         (write_object_file): Call obj_frob_file after setting the symbols,

 156         Patches from Eric Youngdale:
 157         * make-gas.com: Find obstack.obj if it's not in the current
 158         directory.
 159         * read.c (s_ignore): Don't declare is_end_of_line.  It's
 160         redundant, and triggers a VMS gcc compiler bug.
 161
 162         * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
 163         current segment as an argument.  (Ignored in all cases but VMS.)
 164         All callers and definitions changed.
 165
 166 Tue Mar  2 11:56:19 1993  Ian Lance Taylor  (ian@cygnus.com)
 167
 168         * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING

 170
 171 Tue Mar  2 08:53:34 1993  Ken Raeburn  (raeburn@cygnus.com)
 172
 173         * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,
 174         so "~0x80" won't be rejected.
 175
 176         * config/obj-elf.c: No longer include elf/reloc.h.
 177         (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
 178         (obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out

 180         (obj_elf_xstab): New routine.
 181         (obj_elf_set_size): Call as_warn, not fprintf.  Pass desired
 182         argument to s_ignore.  Put "#if 0" around unused code.
 183         (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
 184         Call elf_xstabs for .stabs and .xstabs operators.
 185
 186         * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
 187

 189         present.
 190
 191         * configure.in: mips-bsd configuration was missing format spec.
 192         Should use aout.
 193
 194         * Makefile.in (Makefile): Depends on configure.in.
 195
 196         * config/tc-mips.c (append_insn): Don't check for alignment of
 197         frag in memory; alignment of instructions in section is a separate
 198         matter.
 199
 200         * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
 201         C availability.
 202
 203         * listing.h: Always provide function declarations, not macros, so
 204         pcc won't lose.
 205
 206 Tue Mar  2 00:50:43 1993  John Gilmore  (gnu@cygnus.com)

 244         * config/obj-aout.c: Use PARAMS macro for declarations.  Remove
 245         "IGNORE_DEBUG" conditional, since both branches are identical.

 264         * write.h (fix_new): Update prototype.
 265
 266         * tc.h (md_operand, md_convert_frag, tc_headers_hook,

 279         (symbol_find, symbol_find_base): Likewise.
 280         (S_IS_*, S_GET_*, S_SET_*) [BFD_ASSEMBLER]: New functions.
 281         * symbols.h: Fix prototypes for new const arguments.  Add

 291         new section/subsection.
 292

 294         (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
 295         for now; should be machine-dependent.
 296
 297         * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
 298         targets, forcing BFD use.

 354
 355         * write.c: Reordered some functions for better inlining.

 399
 400         * subsegs.h (segment_info_type): Always define.  Omit field scnhdr
 401         if not MANY_SEGMENTS.  Define new field bfd_section if

 461         md_relax_table): Use default zero initialization.
 462         (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

 464
 465 Thu Jan  7 08:58:21 1993  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)

 474
 475 Tue Jan  5 08:42:16 1993  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 476
 477         * expr.c (operand): If character other than comma or newline is a
 478         logical end-of-line character, use the newline case.
 479         From Eric Youngdale:
 480         (operand): Set X_add_number field for floating-point numbers.
 481         (operand): Treat zero byte as end-of-operand.
 482
 483         * configure.in (per-target): Look for with_bfd_assembler option.
 484         For now, only accept "no", until the merge is done.
 485
 486         Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
 487         * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
 488           config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
 489         * read.c: Finish conversion to S_* macros in the VMS only
 490           parts of the program. Add "const" modifier to hex_value.
 491         * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
 492           "ifdef OBJ_VMS".
 493         * expr.c: Add "const" modifier to hex_value.
 494         * symbols.c: Finish conversion to S_* macros in the VMS only
 495           parts of the program.  Add "const" modifier to
 496           md_[long,short]_jump_size. Remove declaration of const_flag
 497           (which will be declared in obj-vms.h).
 498         * write.c: Add "const" modifier to md_[long,short]_jump_size.
 499           Fix arguments to VMS_write_object_file.
 500         * config-gas.com: New file.  Script for VMS systems to set up the
 501           configuration to build gas for VMS, and create config.status.
 502         * make-gas.com: Redone to work with new scheme.
 503         * obj-vms.c: Patch to fix bug where we were not correctly parsing the
 504           stabs directives.
 505         * obj-vms.c:  Define macros COPY_LONG and COPY_SHORT which
 506           will swap bytes if needed on a big endian system.  Use throughout
 507           as needed.
 508         * obj-vms.c (obj_aout_stab):  Add code to generate listing file.
 509         * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
 510           types of malformed stabs.  Change parsing algorithm so that we are
 511           more certain of having all of the information that we need on hand.
 512         * obj-vms.c (final_forward_reference):  New function, used to help
 513           resolve the data types of as many struct elements as possible
 514           when some part of the struct is not fully defined by the compiler.
 515         * obj-vms.c (VMS_LSYM_Parse):  Correctly handle case of continuation
 516           stabs directives.
 517         * obj-vms.c (VMS_write_object_file): Define all vtable psects
 518           as symbols as well in the object file.  Look for external functions
 519           that start with "__vt.", and turn them into variables, since the
 520           g++ compiler is incapable of doing this.
 521         * tc-vax.c: Add '1' option for backward compatibility with older GCC
 522           versions.
 523         * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
 524         * input-scrub.c (as_where): Fix bug where as would crash if we did not
 525           have the name of the source file yet.
 526         * config/ho-vms.h: define HO_VMS, not HO_VAX.
 527
 528 Mon Jan  4 05:17:26 1993  Ken Raeburn  (raeburn@cygnus.com)
 529
 530         * read.c (s_data): Always use "data_section", since it'll map to
 531         SEG_DATA or SEG_E1 if needed.
 532         (s_lcomm): Likewise with bss_section.
 533         (s_fill): Use memset, not bzero.
 534
 535 Thu Dec 31 04:29:27 1992  Ken Raeburn  (raeburn@kr-pc.cygnus.com)
 536
 537         * read.c: Deleted some code under "#ifdef DONTDEF" that was for
 538         handling GDB symbol table data.
 539
 540         * config/obj-aout.h (segment_name): Delete definition.
 541         (seg_name): Delete declaration.
 542         * config/obj-bout.h (segment_name, seg_name): Ditto.
 543         * config/obj-vms.h (segment_name, seg_name): Ditto.
 544         * config/obj-coff.h (segment_name): Ditto.

 546
 547         * Changes for BFD_ASSEMBLER:

 549         BFD_ASSEMBLER.
 550         (obj_header_append, obj_pre_write_hook): Ditto.
 551         * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
 552         (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
 553         (segment_name) If BFD_ASSEMBLER, look up BFD section name;
 554         otherwise, use seg_name array.
 555         (seg_name): Declare only if not BFD_ASSEMBLER.
 556         (section_alignment): Declare only if not BFD_ASSEMBLER.
 557         (big_section, reg_section, pass1_section, diff_section,
 558         absent_section, text_section, data_section, bss_section): If
 559         BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
 560         mapping to segT enum values.
 561         (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
 562         if these are used or defined, if BFD_ASSEMBLER.
 563         (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
 564         subseg_new split into two functions.
 565         (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
 566
 567         * as.h (volatile): Don't define if already defined.
 568         (had_errors, had_warnings): Provide prototypes for ANSI C even if
 569         NO_STDARG.
 570         (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
 571         declare with format attribute for -Wformat checking.
 572
 573 Wed Dec 30 10:18:57 1992  Ian Lance Taylor  (ian@cygnus.com)
 574
 575         * app.c, config/tc-*.c: Don't include read.h, since it is already
 576         included by as.h.
 577
 578         * These are based on patches from Minh Tran-le
 579         <mtranle@paris.intellicorp.com>.
 580         * configure.in (i[34]86-ibm-aix*): Accept i486 for host.  Use
 581         obj_format coffbfd and gas_target i386coff for target.
 582         (i[34]86-*-isc*): New host (uses sysv).
 583         * config/i386aix.mt: Removed (no longer used).
 584         * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
 585         (MINUS_G): Removed.
 586         (LDFLAGS): Added, defined as -shlib.
 587         * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
 588         * config/te-sco386.h (LOCAL_LABEL): Don't define.
 589         (DOT_LABEL_PREFIX): Define.
 590         * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
 591         name rather than L0\001.
 592         * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
 593         local_bss_counter.
 594         * symbols.c, symbols.h (local_bss_counter): Removed.
 595         * write.c (write_object_file): bss no longer uses
 596         local_bss_counter.  Pass correct data and bss size to
 597         VMS_write_object_file.
 598         * config/obj-vms.c (VMS_write_object_file): Accept bss size as
 599         argument, rather than using local_bss_counter.
 600         * config/tc-m88k.c (s_bss): Don't use local_bss_counter.
 601         * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.

 603         (size_section): Restored sanity check.
 604         (do_relocs_for): Base section address on s_paddr rather than
 605         computing it.  Adjust a29k R_IHIHALF special case to account for
 606         section paddr (used to require paddr to be zero).  If there are no
 607         reclos, set s_relptr to 0.  Set relocation size in object_headers.
 608         (fill_section): Always set s_vaddr here, removing
 609         ZERO_BASED_SEGMENTS case.  Force s_scnptr for bss to 0.  Don't set
 610         NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
 611         Set STYP_INFO for .comment.
 612         (coff_header_append): Use object headers and H_{SET,GET}_* macros.
 613         Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
 614         (crawl_symbols): Handle 8 character section name correctly.  Use
 615         H_{SET,GET}_* macros.
 616         (do_linenos_for): Set lineno size in object_headers.
 617         (write_object_file): Use H_{SET,GET}_* macros.  Don't bother to
 618         set s_vaddr here.  If string_byte_count remains 4, set it back to
 619         0, and only write strings out if there are some.  Call
 620         fill_section before do_relocs_for and do_linenos_for.
 621         (obj_coff_section): Handle optional quoted second argument giving
 622         section characteristics.
 623         (obj_coff_bss): Added to handle .bss.
 624         (obj_coff_ident): Added to handle .ident (puts string in .comment
 625         section).
 626         (obj_coff_lcomm): Put common symbols in .bss, not .data.
 627         (fixup_mdeps): Change to segment.  Call frag_wane after
 628         md_convert_frag.
 629         (fixup_segment): Explicitly check S_IS_COMMON before making 386
 630         adjustment (already happened only for common symbols, but this is
 631         clearer).
 632         * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
 633         * config/tc-i386.c (s_bss): Don't use if I386COFF.
 634         (md_pseudo_table): Ignore .optim and .noopt.
 635         (tc_coff_sizemachdep): New function.
 636         * config/tc-i386.h (REVERSE_SORT_RELOCS): Undef, for SVR3
 637         compatibility.
 638         (LOCAL_LABEL): Removed definition.
 639         (DOT_LABEL_PREFIX): Defined.
 640
 641 Mon Dec 28 10:32:05 1992  Ken Raeburn  (raeburn@cygnus.com)
 642
 643         * app.c (app_push): Use memcpy, not bcopy.
 644         (do_scrub_next_char): For \", return " not '.
 645         (symbol_chars): Now const.
 646
 647         * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
 648         and "0b".  If LOCAL_LABELS_DOLLAR, check for "0$".
 649
 650         * config/obj-coff.h: Don't use #elif.
 651
 652         * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't

 656
 657         * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is
 658         already defined.
 659
 660 Tue Dec 15 12:40:11 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
 661
 662         * app.c (do_scrub_begin): allow single quote strings if so
 663         configured.
 664
 665         * config/*z8k*: checkpoint
 666
 667 Sun Dec 13 00:04:38 1992  Ian Lance Taylor  (ian@cygnus.com)
 668
 669         * read.c (read_a_source_file): avoid calling xmalloc (0).
 670
 671 Sat Dec 12 15:26:34 1992  Ian Lance Taylor  (ian@cygnus.com)
 672
 673         * listing.c: Call xmalloc, not malloc; don't declare malloc.
 674
 675         * Changes to support SCO 3.2v4:
 676         * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
 677         SEG_BSS, fill with NOP_OPCODE.
 678         * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
 679         * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
 680         using ZERO_BASED_SEGMENTS.
 681         (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
 682         never set segment address for SEG_E2 (.bss) and don't write out
 683         SEG_E2 contents.  Set .init and .fini sections to STYP_TEXT.
 684         (obj_coff_endef): Don't merge labels or symbols awaiting forward
 685         definitions, and don't merge tags with non-tags.  Check for .bf
 686         rather than just checking whether the second character is b and
 687         the third character is f.
 688         (obj_coff_val): gcc can generate values which we don't handle
 689         correctly; discard information for now, since it only affects the
 690         debugging information.
 691         (tag_find_or_name): Don't insert tags in the symbol table.
 692         (yank_symbols): Don't merge labels.
 693         (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
 694         already defined.  Fill subsegments with NOP_OPCODE, not 0.  Don't
 695         set segment address if ZERO_BASED_SEGMENTS.
 696         (obj_coff_section): Accept and ignore a trailing quoted string, as
 697         used in AT&T i386 syntax.
 698         (fixup_segment): Take segment as argument.  On the i386, adjust PC
 699         relative addends by the segment vaddr.
 700         * tc-i386.h: Define SUB_SEGMENT_ALIGN.
 701         * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
 702         * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

 862         putting them in the symbol table.
 863         * tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not
 864         M68KCOFF.
 865
 866         * obj-coffbfd.c (fill_section): set STYP_NOLOAD bit for .bss
 867         section.
 868
 869         * atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
 870         comment_chars, line_comment_chars and line_seperator_chars
 871         consistently const, and always initialized them.  Included read.h.

 883         TC_I960 is defined.
 884
 885         * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.
 886         (m68k_ip): Don't warn about bignum used as float bit-pattern.
 887
 888         * obj-coff.c: Replaced ANSI and non-ANSI function declarations

 900
 901         * version.c: Put conditional "const" before version_string, not

 915         obj-coffbfd.c (do_relocs_for, write_object_file): set segment

 918         (fill_section): segment addresses now set in write_object_file.
 919         (fill_section): Don't set STYP_NOLOAD for .bss section.

 930         hosts, use the sysv configuration for solaris2
 931
 932 Mon Oct  5 09:28:57 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
 933
 934          fix i960+non-bfd coff bit rot.
 935         * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
 936         support for C source listings. (obj_coff_endef): look in the right

 954
 955 Tue Sep 29 10:51:55 1992  Ian Lance Taylor  (ian@cygnus.com)
 956
 957         * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
 958         #elif, since it is not supported by old compilers.
 959         ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
 960         couple of expressions in tc-m68k.c.
 961
 962 Mon Sep 28 21:18:24 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 963
 964         * read.c (cons): If NO_RELOC is defined, use it.
 965
 966         * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
 967
 968 Fri Sep 25 18:18:52 1992  Ian Lance Taylor  (ian@cygnus.com)
 969
 970         * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
 971         local labels to start with a .) and set REGISTER_PREFIX to %.
 972         tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
 973
 974 Fri Sep 25 17:53:43 1992  John Gilmore  (gnu@cygnus.com)

 988 Tue Sep 22 13:02:07 1992  Sean Eric Fagan  (sef@cygnus.com)
 989
 990         * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
 991         sections starting from zero, rather than making them consecutive.
 992         This makes subsequent reloc calculations easier, esp if the object
 993         format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
 994         allocate lcomm in .data rather than in .bss.  It seems that some
 995         tools can't cope with a non-zero sized bss before linkage.
 996
 997 Tue Sep 22 15:10:51 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 998
 999         * tc-m68k.c: Replace "enum m68k_architecture" with "int"
1000         throughout.  That enum no longer means what we thought it meant.

1003         "-mno-688[58]1" options.

1022
1023         * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
1024         .word is < -32768 or > 32767.  The -J flag causes the error to be
1025         ignored.  This is to catch over-sized switches generated by gcc on
1026         systems which don't support the broken .word hack.
1027         as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.

1061
1062         * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
1063          Motorola and MIT syntax; gas can now assemble either type of
1064          file.
1065         tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

1106
1107         * config/tc-m68k.c (init_table): Now const.  Always include 68851
1108         data, so that "bc" is available to 68040 cache instructions.
1109         Added "tt0", "tt1", and 68ec030 variants.

1143 Wed Aug 19 11:20:59 1992  Ian Lance Taylor  (ian@cygnus.com)
1144
1145         * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
1146         written with indirection on the last two operands, which can be
1147         either data or address registers.  Added a new operand type 'r'
1148         which accepts either register type.  Added '(' to notend stuff in

1375
1376         * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
1377         calc the base of relocs correctly.
1378         * tc-a29k.c (parse_operand): allow expressions to be in any section.
1379

1391         * Makefile.in: the tooldir copy of gas goes directly in tooldir.
1392
1393 Tue Apr 14 14:50:22 1992  Ken Raeburn  (Raeburn@Cygnus.COM)
1394
1395         * write.c (write_object_file): For b.out format, round up section
1396         start addresses to match required alignment.
1397
1398 Thu Apr  9 05:45:29 1992  Ken Raeburn  (Raeburn@Cygnus.COM)
1399
1400         * Makefile.in (install): Install into $(tooldir)/bin, since that's
1401         where gcc looks for it.
1402
1403 Tue Apr  7 15:12:15 1992  Sean Eric Fagan  (sef@cygnus.com)
1404
1405         * Makefile.in:  Changed some lines to be less confusing for some

1420
1421         * Makefile.in: pass down MAKEINFO explicitly on info.

1424
1425 Fri Mar 13 08:03:03 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
1426
1427         * flonum-const.c: renamed flonum-konst.c to stop dos name

1429
1430 Thu Mar 12 04:42:38 1992  K. Richard Pixley  (rich@cygnus.com)
1431
1432         * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from

1434

1436
1437         * configure.in: vxworks68 gets te-sun3.h.
1438
1439         * expr.c: remove limitation that local_labels_dollar or
1440           local_labels_fb must be < 10.
1441
1442         * symbols.c: remove local_labels_dollar, replace with a function
1443           interface for a sparse array.  All users adjusted.
1444
1445         * te-sun3.h: add LOCAL_LABELS_DOLLAR.
1446
1447 Sat Mar  7 00:06:25 1992  K. Richard Pixley  (rich@rtl.cygnus.com)
1448
1449         * doc/Makefile.in: commented out line for building as-all.texinfo.
1450           This is temporary.
1451
1452         * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
1453
1454 Fri Mar  6 21:57:18 1992  K. Richard Pixley  (rich@cygnus.com)

1465
1466 Sat Feb 29 13:59:10 1992  Michael Tiemann  (tiemann@cygnus.com)
1467
1468         * Makefile.in (strerror.o): Add rule so that broken Sun make can
1469         work in subdirs.
1470
1471 Wed Feb 26 19:26:28 1992  Steve Chamberlain  (sac at thepub.cygnus.com)
1472
1473         * read.c, obj-coffbfd.c : fix h8300 specific bit rot
1474
1475         * expr.c (operand): if can't work out what sort of operand it is,
1476         then look through FLT_CHARS for a hint.
1477
1478 Wed Feb 26 18:04:40 1992  K. Richard Pixley  (rich@cygnus.com)
1479
1480         * Makefile.in, configure.in: removed traces of namesubdir,
1481           -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
1482           copyrights to '92, changed some from Cygnus to FSF.
1483
1484         * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
1485           -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
1486           copyrights to '92, changed some from Cygnus to FSF.
1487
1488 Tue Feb 25 14:17:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
1489
1490         * expr.c: If an expression is single comma, then return with
1491         SEG_ABSENT rather than an error - since the sparc front end does
1492         really strange things with things like fbge,a
1493
1494         * as.h: include bfd.h if using many sections
1495         * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
1496         local labels didn't work.
1497         * listing.c (list_symbol_table): don't core dump when there's no
1498         symbol there.
1499         * write.c, write.h: call fix_new with the right number of args on
1500         the H8.
1501         * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
1502         errors nices
1503
1504 Sat Feb 22 12:26:28 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
1505
1506         * app.c: MRI compatibility - allow single quote to start a string.
1507         * as.c: fix typo recently introduced.
1508         * as.h : Don't include aout/reloc.h - it's not right for COFF!
1509         * expr.c: Much rewriting, to accomodate MRI syntax for
1510         expressions. Also easier to read now.
1511         * listing.c: Put back defuns
1512         * read.c: modified to accept MRI syntax, put back listing pseudo
1513         ops so that an assembler built with NO_LISTING ignores list ops
1514         rather than pukes.
1515         * write.c, write.h: fixs - only keep a reloc type in a fix if the target
1516         machine is a SPARC or a 29K.
1517         * config/obj-aout.c: added s_sect pseudo op
1518         * config/obj-coffbfd.c: lints, set the filehdr flags right and
1519         fill in the timestamp.
1520         * config/obj-coffbfd.h: Since we don't include aout/reloc.h
1521         anymore, define all the relocs which the tc-<x> bit will use so we
1522         can translate from them to the coff types.
1523         * config/tc-a29k.c: reloc_type isn't ane enum any more
1524         * config/tc-m68k.c: Added NO_RELOC definition.
1525
1526 Fri Feb 21 06:21:07 1992  K. Richard Pixley  (rich@rtl.cygnus.com)
1527
1528         * Makefile.in: put header files before C source for TAGS; remove
1529           references to non-existent syscalls.h.
1530
1531         * read.c, write.c subsegs.c: back out the .bss changes.
1532
1533         * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
1534
1535         * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
1536
1537         * a.out.h: removed.
1538
1539 Fri Feb 21 01:08:48 1992  Minh Tran-Le (TRANLE@INTELLICORP.COM)
1540
1541         * symbols.c (local_label_name): symbols now start with ^A.
1542
1543         * read.c, subsegs.c, write.c obj-coff.c: added handling of
1544           `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
1545           generate these sections.  .align: will use NOP_OPCODE or 0
1546           for padding. This is just for being nice to the
1547           disassembler.
1548
1549         * expr.c (operand): changed to generate local label "\001L0"
1550           starting with a ^A so that it is recognized as a local label.
1551
1552         * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
1553
1554         * tc-i386.c: tc-i386.c: added handling of the following opcodes:
1555           i/o opcodes - inb, inw, outb and outw.  string manipulation with
1556           att syntax - scmp, slod, smov, ssca, ssto.
1557
1558         * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
1559           to just after .file .
1560
1561           In obj_crawl_symbol_chain() where it tries to put the external
1562           symbols apart, with the condition:
1563             (!S_IS_DEFINED(symbolP) &&
1564              !S_IS_DEBUG(symbolP) &&
1565              !SF_GET_STATICS(symbolP))
1566           it was moving too many symbols out. So I switch it back to the
1567           condition:
1568             (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
1569
1570           In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
1571           so that we don't use the F_RELFLG which make the linker complain
1572           that somebody has stripped the relocation info.
1573
1574           Also, the AIX ld program require that the relocation table
1575           is sorted by r_vaddr like the standard ATT assembler does.
1576
1577           [he also changed the sizeof(struct ...)'s into the coff
1578           style FOOSZ macros.  I'm not sure this is right, but I can't
1579           remember why.  xoxorich.]

1581 Fri Feb 21 01:08:48 1992  K. Richard Pixley  (rich@cygnus.com)
1582
1583         * Makefile.in, configure.in, doc: use the doc.  Build it, install
1584           it, clean it, etc.
1585
1586 Tue Feb 18 02:21:25 1992  K. Richard Pixley  (rich at cygnus.com)
1587
1588         * read.c: white space and comments only.
1589
1590         * configure.in: use the new atof-ns32.c for ns32k.
1591
1592         * write.c: comment change only.
1593
1594         * tc-m88k.[hc]: pulled in from hack's unfinished work.  These
1595           aren't yet integrated.
1596
1597         * tc-i860.[hc]: blew off the dust.  Something must still be done
1598           about conflicting relocation types.
1599
1600         * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
1601           real thing.
1602
1603         * tc-i960.c, tc-sparc.c: white space and comments only.
1604
1605         * tc-a29k.h: delete duplicate macro definition.
1606
1607         * new file atof-ns32k.c copied from hack's last unreleased gas.
1608
1609 Mon Feb 17 07:51:06 1992  K. Richard Pixley  (rich at cygnus.com)
1610
1611         * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
1612           rather than abort.
1613
1614         * nearly everything.  flush ChangeLog, package as gas-1.92.1.
1615           ChangeLog's prior to this are sketchy at best.  I have logs.
1616           They just aren't ChangeLogs.
