  32         by the section vma.
  33
  34         * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is

  50
  51         * Makefile.in (config.h): Create file, writing out definitions of

  53         (ALL_CFLAGS): No longer define TARGET_CPU.
  54
  55         * Makefile.in (check): Print a message, instead of quitting
  56         silently.
  57
  58         * as.c (main): Don't catch any signals, for now.
  59
  60         * version.c: Deleted.

  92         (struct loc, struct proc, struct file): Moved to tc-mips.c within
  93         #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
  94         * config/tc-mips.c: Rearranged for ECOFF support.  Added
  95         prototypes for all static functions.  Moved existing minimal
  96         debugging format support info #ifndef OBJ_ECOFF blocks.
  97         (macro_build_lui): Eliminated sign_extend argument, because ECOFF
  98         does not support a non sign extended high 16 bits reloc.  Adjusted
  99         all callers accordingly.
 100         (tc_get_register): Renamed from get_register, and made non-static.
 101
 102         * config/mips-big.mt, config/mips-lit.mt: New files.  Define

 116         is not NULL.
 117         (write_object_file): Call obj_frob_file after setting the symbols,

 140         Patches from Eric Youngdale:
 141         * make-gas.com: Find obstack.obj if it's not in the current
 142         directory.
 143         * read.c (s_ignore): Don't declare is_end_of_line.  It's
 144         redundant, and triggers a VMS gcc compiler bug.
 145
 146         * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
 147         current segment as an argument.  (Ignored in all cases but VMS.)
 148         All callers and definitions changed.
 149
 150 Tue Mar  2 11:56:19 1993  Ian Lance Taylor  (ian@cygnus.com)

 155 Tue Mar  2 08:53:34 1993  Ken Raeburn  (raeburn@cygnus.com)
 156
 157         * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,
 158         so "~0x80" won't be rejected.
 159
 160         * config/obj-elf.c: No longer include elf/reloc.h.
 161         (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
 162         (obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out

 164         (obj_elf_xstab): New routine.
 165         (obj_elf_set_size): Call as_warn, not fprintf.  Pass desired
 166         argument to s_ignore.  Put "#if 0" around unused code.
 167         (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
 168         Call elf_xstabs for .stabs and .xstabs operators.
 169
 170         * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
 171

 173         present.
 174
 175         * configure.in: mips-bsd configuration was missing format spec.
 176         Should use aout.
 177
 178         * Makefile.in (Makefile): Depends on configure.in.
 179
 180         * config/tc-mips.c (append_insn): Don't check for alignment of
 181         frag in memory; alignment of instructions in section is a separate
 182         matter.
 183
 184         * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
 185         C availability.
 186
 187         * listing.h: Always provide function declarations, not macros, so
 188         pcc won't lose.
 189

 282         targets, forcing BFD use.

 338
 339         * write.c: Reordered some functions for better inlining.

 383
 384         * subsegs.h (segment_info_type): Always define.  Omit field scnhdr

 459 Tue Jan  5 08:42:16 1993  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 460
 461         * expr.c (operand): If character other than comma or newline is a
 462         logical end-of-line character, use the newline case.
 463         From Eric Youngdale:
 464         (operand): Set X_add_number field for floating-point numbers.
 465         (operand): Treat zero byte as end-of-operand.
 466
 467         * configure.in (per-target): Look for with_bfd_assembler option.
 468         For now, only accept "no", until the merge is done.
 469
 470         Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
 471         * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
 472           config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
 473         * read.c: Finish conversion to S_* macros in the VMS only
 474           parts of the program. Add "const" modifier to hex_value.
 475         * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
 476           "ifdef OBJ_VMS".
 477         * expr.c: Add "const" modifier to hex_value.
 478         * symbols.c: Finish conversion to S_* macros in the VMS only
 479           parts of the program.  Add "const" modifier to
 480           md_[long,short]_jump_size. Remove declaration of const_flag
 481           (which will be declared in obj-vms.h).
 482         * write.c: Add "const" modifier to md_[long,short]_jump_size.
 483           Fix arguments to VMS_write_object_file.
 484         * config-gas.com: New file.  Script for VMS systems to set up the
 485           configuration to build gas for VMS, and create config.status.
 486         * make-gas.com: Redone to work with new scheme.
 487         * obj-vms.c: Patch to fix bug where we were not correctly parsing the
 488           stabs directives.
 489         * obj-vms.c:  Define macros COPY_LONG and COPY_SHORT which
 490           will swap bytes if needed on a big endian system.  Use throughout
 491           as needed.
 492         * obj-vms.c (obj_aout_stab):  Add code to generate listing file.
 493         * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
 494           types of malformed stabs.  Change parsing algorithm so that we are
 495           more certain of having all of the information that we need on hand.
 496         * obj-vms.c (final_forward_reference):  New function, used to help
 497           resolve the data types of as many struct elements as possible
 498           when some part of the struct is not fully defined by the compiler.
 499         * obj-vms.c (VMS_LSYM_Parse):  Correctly handle case of continuation
 500           stabs directives.
 501         * obj-vms.c (VMS_write_object_file): Define all vtable psects
 502           as symbols as well in the object file.  Look for external functions
 503           that start with "__vt.", and turn them into variables, since the
 504           g++ compiler is incapable of doing this.
 505         * tc-vax.c: Add '1' option for backward compatibility with older GCC
 506           versions.
 507         * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
 508         * input-scrub.c (as_where): Fix bug where as would crash if we did not
 509           have the name of the source file yet.
 510         * config/ho-vms.h: define HO_VMS, not HO_VAX.
 511
 512 Mon Jan  4 05:17:26 1993  Ken Raeburn  (raeburn@cygnus.com)
 513
 514         * read.c (s_data): Always use "data_section", since it'll map to
 515         SEG_DATA or SEG_E1 if needed.
 516         (s_lcomm): Likewise with bss_section.
 517         (s_fill): Use memset, not bzero.
 518
 519 Thu Dec 31 04:29:27 1992  Ken Raeburn  (raeburn@kr-pc.cygnus.com)
 520
 521         * read.c: Deleted some code under "#ifdef DONTDEF" that was for
 522         handling GDB symbol table data.
 523
 524         * config/obj-aout.h (segment_name): Delete definition.
 525         (seg_name): Delete declaration.
 526         * config/obj-bout.h (segment_name, seg_name): Ditto.

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

 587         (size_section): Restored sanity check.
 588         (do_relocs_for): Base section address on s_paddr rather than
 589         computing it.  Adjust a29k R_IHIHALF special case to account for
 590         section paddr (used to require paddr to be zero).  If there are no
 591         reclos, set s_relptr to 0.  Set relocation size in object_headers.
 592         (fill_section): Always set s_vaddr here, removing
 593         ZERO_BASED_SEGMENTS case.  Force s_scnptr for bss to 0.  Don't set
 594         NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
 595         Set STYP_INFO for .comment.
 596         (coff_header_append): Use object headers and H_{SET,GET}_* macros.
 597         Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
 598         (crawl_symbols): Handle 8 character section name correctly.  Use
 599         H_{SET,GET}_* macros.
 600         (do_linenos_for): Set lineno size in object_headers.
 601         (write_object_file): Use H_{SET,GET}_* macros.  Don't bother to
 602         set s_vaddr here.  If string_byte_count remains 4, set it back to
 603         0, and only write strings out if there are some.  Call
 604         fill_section before do_relocs_for and do_linenos_for.
 605         (obj_coff_section): Handle optional quoted second argument giving
 606         section characteristics.
 607         (obj_coff_bss): Added to handle .bss.
 608         (obj_coff_ident): Added to handle .ident (puts string in .comment
 609         section).
 610         (obj_coff_lcomm): Put common symbols in .bss, not .data.
 611         (fixup_mdeps): Change to segment.  Call frag_wane after
 612         md_convert_frag.
 613         (fixup_segment): Explicitly check S_IS_COMMON before making 386
 614         adjustment (already happened only for common symbols, but this is
 615         clearer).
 616         * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
 617         * config/tc-i386.c (s_bss): Don't use if I386COFF.
 618         (md_pseudo_table): Ignore .optim and .noopt.
 619         (tc_coff_sizemachdep): New function.
 620         * config/tc-i386.h (REVERSE_SORT_RELOCS): Undef, for SVR3
 621         compatibility.
 622         (LOCAL_LABEL): Removed definition.
 623         (DOT_LABEL_PREFIX): Defined.

 625 Mon Dec 28 10:32:05 1992  Ken Raeburn  (raeburn@cygnus.com)
 626
 627         * app.c (app_push): Use memcpy, not bcopy.
 628         (do_scrub_next_char): For \", return " not '.
 629         (symbol_chars): Now const.
 630
 631         * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
 632         and "0b".  If LOCAL_LABELS_DOLLAR, check for "0$".
 633
 634         * config/obj-coff.h: Don't use #elif.
 635
 636         * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
 637         have it.  (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
 638
 639 Wed Dec 16 12:12:33 1992  Ian Lance Taylor  (ian@cygnus.com)

 657         * listing.c: Call xmalloc, not malloc; don't declare malloc.
 658
 659         * Changes to support SCO 3.2v4:
 660         * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
 661         SEG_BSS, fill with NOP_OPCODE.
 662         * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
 663         * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
 664         using ZERO_BASED_SEGMENTS.
 665         (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
 666         never set segment address for SEG_E2 (.bss) and don't write out
 667         SEG_E2 contents.  Set .init and .fini sections to STYP_TEXT.
 668         (obj_coff_endef): Don't merge labels or symbols awaiting forward
 669         definitions, and don't merge tags with non-tags.  Check for .bf
 670         rather than just checking whether the second character is b and
 671         the third character is f.
 672         (obj_coff_val): gcc can generate values which we don't handle
 673         correctly; discard information for now, since it only affects the
 674         debugging information.
 675         (tag_find_or_name): Don't insert tags in the symbol table.
 676         (yank_symbols): Don't merge labels.
 677         (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
 678         already defined.  Fill subsegments with NOP_OPCODE, not 0.  Don't
 679         set segment address if ZERO_BASED_SEGMENTS.
 680         (obj_coff_section): Accept and ignore a trailing quoted string, as
 681         used in AT&T i386 syntax.
 682         (fixup_segment): Take segment as argument.  On the i386, adjust PC
 683         relative addends by the segment vaddr.
 684         * tc-i386.h: Define SUB_SEGMENT_ALIGN.
 685         * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
 686         * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

 697         power-of-two alignment for .align.
 698
 699         * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
 700         and leave everything else alone.

 705
 706         * write.c: Conditionalize on OBJ_VMS, not VMS.
 707         (magic_number_for_object_file): Don't define if OBJ_VMS.

 730
 731         * doc/as.texinfo: Regrouped documentation of some command-line
 732         options.  Updated options documentation for m68k.  Some minor
 733         wording/punctuation changes.

 814
 815         * all files: Whitespace changes for GNU indentation style, done by
 816         GNU `indent'.  Some cleanup still needed, especially of comments.

 844         the register name.
 845         (insert_reg): put REGISTER_PREFIX before register names before
 846         putting them in the symbol table.
 847         * tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not
 848         M68KCOFF.
 849
 850         * obj-coffbfd.c (fill_section): set STYP_NOLOAD bit for .bss
 851         section.
 852
 853         * atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
 854         comment_chars, line_comment_chars and line_seperator_chars
 855         consistently const, and always initialized them.  Included read.h.
 856
 857 Thu Nov  5 17:55:41 1992  Jim Wilson  (wilson@sphagnum.cygnus.com)

 862
 863 Wed Nov  4 07:50:46 1992  Ken Raeburn  (raeburn@cygnus.com)
 864
 865         * obj-coff.c (callj_table): Delete global variable.
 866         (obj_emit_relocations): Define it locally here, and only if
 867         TC_I960 is defined.
 868
 869         * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.
 870         (m68k_ip): Don't warn about bignum used as float bit-pattern.
 871
 872         * obj-coff.c: Replaced ANSI and non-ANSI function declarations
 873         with a single set using PARAMS macro.
 874
 875         * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length
 876         of 2.
 877
 878         * tc-i960.c: Missed a couple of 0->NO_RELOC conversions.
 879
 880         * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
 881         so widening works consistently.
 882
 883 Wed Oct 28 08:52:34 1992  Ken Raeburn  (raeburn@cygnus.com)
 884
 885         * version.c: Put conditional "const" before version_string, not
 886         before dummy function for VMS.  Now version 1.91.03.
 887
 888         * app.c (do_scrub_next_char): Need double-\ before `000' to show
 889         printed rep of null character.
 890
 891 Fri Oct 23 14:40:38 1992  Ian Lance Taylor  (ian@cygnus.com)
 892
 893         * obj-coffbfd.c (write_object_file): check return value of
 894         bfd_close_all_done.
 895
 896 Tue Oct 20 12:18:08 1992  Ian Lance Taylor  (ian@cygnus.com)
 897
 898         * Support for i386-sysv.
 899         obj-coffbfd.c (do_relocs_for, write_object_file): set segment
 900         addresses to reasonable sizes.  New define ZERO_BASED_SEGMENTS can
 901         be used to set them all to zero as was done before.
 902         (fill_section): segment addresses now set in write_object_file.
 903         (fill_section): Don't set STYP_NOLOAD for .bss section.
 904         (fixup_segment): 386 uses strange common symbol format.
 905         tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
 906         compatibility with SVR3.2 linker.

 913         * configure.in: differentiate between SunOS 4 and Solaris2 for Sun4
 914         hosts, use the sysv configuration for solaris2
 915
 916 Mon Oct  5 09:28:57 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
 917
 918          fix i960+non-bfd coff bit rot.
 919         * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
 920         support for C source listings. (obj_coff_endef): look in the right
 921         part of the symbol for the symbol name
 922
 923         * tc-m68k.c (get_num): make it work for all segments, not just the
 924         first three.
 925
 926 Mon Oct  5 03:30:36 1992  Mark Eichin  (eichin at tweedledumber.cygnus.com)
 927
 928         * configure.in: recognize i386-*-bsd emulation.

 934 Tue Sep 29 12:22:52 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
 935
 936         * obj-coffbfd.c (write_object_file): don't fixup for the z8k
 937         * tc-z8k.c: lots of bug fixes
 938
 939 Tue Sep 29 10:51:55 1992  Ian Lance Taylor  (ian@cygnus.com)
 940
 941         * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
 942         #elif, since it is not supported by old compilers.
 943         ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
 944         couple of expressions in tc-m68k.c.
 945
 946 Mon Sep 28 21:18:24 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 947
 948         * read.c (cons): If NO_RELOC is defined, use it.
 949
 950         * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
 951
 952 Fri Sep 25 18:18:52 1992  Ian Lance Taylor  (ian@cygnus.com)
 953
 954         * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
 955         local labels to start with a .) and set REGISTER_PREFIX to %.
 956         tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
 957
 958 Fri Sep 25 17:53:43 1992  John Gilmore  (gnu@cygnus.com)
 959
 960         * messages.c:  Comment changes.
 961
 962 Fri Sep 25 14:12:58 1992  Ken Raeburn  (raeburn@kyriath.cygnus.com)
 963
 964         * as.h: Test if __STDC__ is defined only, don't test its value.
 965         * messages.c: If __STDC__ is not defined, define NO_STDARG.
 966
 967 Thu Sep 24 12:42:32 1992  Brendan Kehoe  (brendan@rtl.cygnus.com)
 968
 969         * listing.c (debugging_pseudo): Add stabs and stabn as things to
 970         ignore.
 971
 972 Tue Sep 22 13:02:07 1992  Sean Eric Fagan  (sef@cygnus.com)
 973
 974         * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
 975         sections starting from zero, rather than making them consecutive.
 976         This makes subsequent reloc calculations easier, esp if the object
 977         format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
 978         allocate lcomm in .data rather than in .bss.  It seems that some
 979         tools can't cope with a non-zero sized bss before linkage.
 980
 981 Tue Sep 22 15:10:51 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 982
 983         * tc-m68k.c: Replace "enum m68k_architecture" with "int"
 984         throughout.  That enum no longer means what we thought it meant.
 985
 986         * tc-m68k.c (md_assemble, md_parse_option): Handle new
 987         "-mno-688[58]1" options.
 988
 989         * tc-m68k.c: Added CPU32 support.
 990
 991 Fri Sep 18 08:02:18 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
 992
 993         * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
 994
 995 Tue Sep 15 17:25:05 1992  Jim Wilson  (wilson@sphagnum.cygnus.com)
 996
 997         * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
 998         Change LIBDEPS dependence to LIBS.
 999
1000 Tue Sep 15 15:32:02 1992  Ian Lance Taylor  (ian@cygnus.com)
1001
1002         * Makefile.in (install): if $(tooldir) exists, install as in
1003         $(tooldir)/bin.
1004
1005 Sun Sep 13 20:30:10 1992  Ian Lance Taylor  (ian@cygnus.com)
1006
1007         * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
1008         .word is < -32768 or > 32767.  The -J flag causes the error to be
1009         ignored.  This is to catch over-sized switches generated by gcc on

1357
1358 Mon May  4 18:56:19 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
1359
1360         * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
1361         calc the base of relocs correctly.
1362         * tc-a29k.c (parse_operand): allow expressions to be in any section.
1363
1364 Mon Apr 27 13:13:31 1992  K. Richard Pixley  (rich@cygnus.com)
1365
1366         * as.c, write.c: use -K rather than -k for the broken word warning
1367           option.

1374
1375         * Makefile.in: the tooldir copy of gas goes directly in tooldir.
1376
1377 Tue Apr 14 14:50:22 1992  Ken Raeburn  (Raeburn@Cygnus.COM)
1378
1379         * write.c (write_object_file): For b.out format, round up section
1380         start addresses to match required alignment.
1381
1382 Thu Apr  9 05:45:29 1992  Ken Raeburn  (Raeburn@Cygnus.COM)
1383
1384         * Makefile.in (install): Install into $(tooldir)/bin, since that's
1385         where gcc looks for it.
1386
1387 Tue Apr  7 15:12:15 1992  Sean Eric Fagan  (sef@cygnus.com)
1388
1389         * Makefile.in:  Changed some lines to be less confusing for some
1390         makes.
1391
1392         * input-file.c:  Conditionalize on _IOFBF, not VMS.

1395         ifdef/else/ifdef etc.
1396
1397 Fri Mar 27 12:21:16 1992  K. Richard Pixley  (rich@cygnus.com)
1398
1399         * symbols.c (fb_label_init): fix sizeof to memset.
1400
1401 Fri Mar 13 15:45:44 1992  K. Richard Pixley  (rich@cygnus.com)
1402
1403         * Makefile.in: install the man page.
1404
1405         * Makefile.in: pass down MAKEINFO explicitly on info.
1406
1407         * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
1408
1409 Fri Mar 13 08:03:03 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
1410
1411         * flonum-const.c: renamed flonum-konst.c to stop dos name
1412         conflict.
1413
1414 Thu Mar 12 04:42:38 1992  K. Richard Pixley  (rich@cygnus.com)
1415
1416         * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
1417           tc-m68k.h to te-sun3.h.
1418
1419 Wed Mar 11 23:32:42 1992  K. Richard Pixley  (rich@cygnus.com)
1420
1421         * configure.in: vxworks68 gets te-sun3.h.
1422
1423         * expr.c: remove limitation that local_labels_dollar or
1424           local_labels_fb must be < 10.
1425
1426         * symbols.c: remove local_labels_dollar, replace with a function
1427           interface for a sparse array.  All users adjusted.
1428
1429         * te-sun3.h: add LOCAL_LABELS_DOLLAR.
1430
1431 Sat Mar  7 00:06:25 1992  K. Richard Pixley  (rich@rtl.cygnus.com)
1432
1433         * doc/Makefile.in: commented out line for building as-all.texinfo.
1434           This is temporary.
1435
1436         * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
1437
1438 Fri Mar  6 21:57:18 1992  K. Richard Pixley  (rich@cygnus.com)
1439
1440         * Makefile.in: added check target.
1441
1442 Tue Mar  3 15:45:56 1992  K. Richard Pixley  (rich@rtl.cygnus.com)
1443
1444         * Makefile.in: added tooldir and program_prefix.
1445
1446 Sun Mar  1 04:43:19 1992  Michael Tiemann  (tiemann@cygnus.com)
1447
1448         * write.{c,h} (fix_new): Make these declarations consistent.
1449
1450 Sat Feb 29 13:59:10 1992  Michael Tiemann  (tiemann@cygnus.com)
1451
1452         * Makefile.in (strerror.o): Add rule so that broken Sun make can
1453         work in subdirs.
1454
1455 Wed Feb 26 19:26:28 1992  Steve Chamberlain  (sac at thepub.cygnus.com)
1456
1457         * read.c, obj-coffbfd.c : fix h8300 specific bit rot
1458
1459         * expr.c (operand): if can't work out what sort of operand it is,
1460         then look through FLT_CHARS for a hint.
1461
1462 Wed Feb 26 18:04:40 1992  K. Richard Pixley  (rich@cygnus.com)
1463
1464         * Makefile.in, configure.in: removed traces of namesubdir,
1465           -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
1466           copyrights to '92, changed some from Cygnus to FSF.
1467
1468         * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
1469           -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
1470           copyrights to '92, changed some from Cygnus to FSF.
1471
1472 Tue Feb 25 14:17:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
1473
1474         * expr.c: If an expression is single comma, then return with
1475         SEG_ABSENT rather than an error - since the sparc front end does
1476         really strange things with things like fbge,a
1477
1478         * as.h: include bfd.h if using many sections
1479         * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
1480         local labels didn't work.
1481         * listing.c (list_symbol_table): don't core dump when there's no
1482         symbol there.
1483         * write.c, write.h: call fix_new with the right number of args on
1484         the H8.
1485         * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
1486         errors nices
1487
1488 Sat Feb 22 12:26:28 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
1489
1490         * app.c: MRI compatibility - allow single quote to start a string.
1491         * as.c: fix typo recently introduced.
1492         * as.h : Don't include aout/reloc.h - it's not right for COFF!
1493         * expr.c: Much rewriting, to accomodate MRI syntax for
1494         expressions. Also easier to read now.
1495         * listing.c: Put back defuns
1496         * read.c: modified to accept MRI syntax, put back listing pseudo
1497         ops so that an assembler built with NO_LISTING ignores list ops
1498         rather than pukes.
1499         * write.c, write.h: fixs - only keep a reloc type in a fix if the target
1500         machine is a SPARC or a 29K.
1501         * config/obj-aout.c: added s_sect pseudo op
1502         * config/obj-coffbfd.c: lints, set the filehdr flags right and
1503         fill in the timestamp.
1504         * config/obj-coffbfd.h: Since we don't include aout/reloc.h
1505         anymore, define all the relocs which the tc-<x> bit will use so we
1506         can translate from them to the coff types.
1507         * config/tc-a29k.c: reloc_type isn't ane enum any more
1508         * config/tc-m68k.c: Added NO_RELOC definition.
1509
1510 Fri Feb 21 06:21:07 1992  K. Richard Pixley  (rich@rtl.cygnus.com)
1511
1512         * Makefile.in: put header files before C source for TAGS; remove
1513           references to non-existent syscalls.h.
1514
1515         * read.c, write.c subsegs.c: back out the .bss changes.
1516
1517         * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
1518
1519         * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
1520
1521         * a.out.h: removed.
1522
1523 Fri Feb 21 01:08:48 1992  Minh Tran-Le (TRANLE@INTELLICORP.COM)
1524
1525         * symbols.c (local_label_name): symbols now start with ^A.
1526
1527         * read.c, subsegs.c, write.c obj-coff.c: added handling of
1528           `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
1529           generate these sections.  .align: will use NOP_OPCODE or 0
1530           for padding. This is just for being nice to the
1531           disassembler.
1532
1533         * expr.c (operand): changed to generate local label "\001L0"
1534           starting with a ^A so that it is recognized as a local label.
1535
1536         * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
1537
1538         * tc-i386.c: tc-i386.c: added handling of the following opcodes:
1539           i/o opcodes - inb, inw, outb and outw.  string manipulation with
1540           att syntax - scmp, slod, smov, ssca, ssto.
1541
1542         * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
1543           to just after .file .
1544
1545           In obj_crawl_symbol_chain() where it tries to put the external
1546           symbols apart, with the condition:
1547             (!S_IS_DEFINED(symbolP) &&
1548              !S_IS_DEBUG(symbolP) &&
1549              !SF_GET_STATICS(symbolP))
1550           it was moving too many symbols out. So I switch it back to the
1551           condition:
1552             (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
1553
1554           In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
1555           so that we don't use the F_RELFLG which make the linker complain
1556           that somebody has stripped the relocation info.
1557
1558           Also, the AIX ld program require that the relocation table
1559           is sorted by r_vaddr like the standard ATT assembler does.
1560
1561           [he also changed the sizeof(struct ...)'s into the coff
1562           style FOOSZ macros.  I'm not sure this is right, but I can't
1563           remember why.  xoxorich.]

1565 Fri Feb 21 01:08:48 1992  K. Richard Pixley  (rich@cygnus.com)
1566
1567         * Makefile.in, configure.in, doc: use the doc.  Build it, install
1568           it, clean it, etc.
1569
1570 Tue Feb 18 02:21:25 1992  K. Richard Pixley  (rich at cygnus.com)
1571
1572         * read.c: white space and comments only.
1573
1574         * configure.in: use the new atof-ns32.c for ns32k.
1575
1576         * write.c: comment change only.
1577
1578         * tc-m88k.[hc]: pulled in from hack's unfinished work.  These
1579           aren't yet integrated.
1580
1581         * tc-i860.[hc]: blew off the dust.  Something must still be done
1582           about conflicting relocation types.
1583
1584         * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
1585           real thing.
1586
1587         * tc-i960.c, tc-sparc.c: white space and comments only.
1588
1589         * tc-a29k.h: delete duplicate macro definition.
1590
1591         * new file atof-ns32k.c copied from hack's last unreleased gas.
1592
1593 Mon Feb 17 07:51:06 1992  K. Richard Pixley  (rich at cygnus.com)
1594
1595         * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
1596           rather than abort.
1597
1598         * nearly everything.  flush ChangeLog, package as gas-1.92.1.
1599           ChangeLog's prior to this are sketchy at best.  I have logs.
1600           They just aren't ChangeLogs.
