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

  23         by the section vma.
  24
  25         * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is

  41
  42         * Makefile.in (config.h): Create file, writing out definitions of
  43         target cpu, alias, and canonical name.
  44         (ALL_CFLAGS): No longer define TARGET_CPU.
  45
  46         * Makefile.in (check): Print a message, instead of quitting
  47         silently.
  48
  49         * as.c (main): Don't catch any signals, for now.
  50
  51         * version.c: Deleted.

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

 106         * write.c (chain_frchains_together): Check that seg_info (section)
 107         is not NULL.
 108         (write_object_file): Call obj_frob_file after setting the symbols,

 130
 131         Patches from Eric Youngdale:
 132         * make-gas.com: Find obstack.obj if it's not in the current
 133         directory.
 134         * read.c (s_ignore): Don't declare is_end_of_line.  It's
 135         redundant, and triggers a VMS gcc compiler bug.
 136
 137         * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
 138         current segment as an argument.  (Ignored in all cases but VMS.)
 139         All callers and definitions changed.
 140
 141 Tue Mar  2 11:56:19 1993  Ian Lance Taylor  (ian@cygnus.com)
 142
 143         * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING

 145
 146 Tue Mar  2 08:53:34 1993  Ken Raeburn  (raeburn@cygnus.com)
 147
 148         * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,
 149         so "~0x80" won't be rejected.
 150
 151         * config/obj-elf.c: No longer include elf/reloc.h.
 152         (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
 153         (obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out

 155         (obj_elf_xstab): New routine.
 156         (obj_elf_set_size): Call as_warn, not fprintf.  Pass desired
 157         argument to s_ignore.  Put "#if 0" around unused code.
 158         (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
 159         Call elf_xstabs for .stabs and .xstabs operators.

 164         present.
 165
 166         * configure.in: mips-bsd configuration was missing format spec.
 167         Should use aout.
 168
 169         * Makefile.in (Makefile): Depends on configure.in.
 170
 171         * config/tc-mips.c (append_insn): Don't check for alignment of
 172         frag in memory; alignment of instructions in section is a separate
 173         matter.
 174
 175         * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
 176         C availability.
 177
 178         * listing.h: Always provide function declarations, not macros, so
 179         pcc won't lose.
 180

 220         "IGNORE_DEBUG" conditional, since both branches are identical.
 221         Use S_SET_TYPE, S_GET_TYPE, and S_GET_DESC instead of directly

 239         * write.h (fix_new): Update prototype.
 240
 241         * tc.h (md_operand, md_convert_frag, tc_headers_hook,

 271
 272         * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
 273         targets, forcing BFD use.

 329
 330         * write.c: Reordered some functions for better inlining.

 374
 375         * subsegs.h (segment_info_type): Always define.  Omit field scnhdr
 376         if not MANY_SEGMENTS.  Define new field bfd_section if

 450 Tue Jan  5 08:42:16 1993  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 451
 452         * expr.c (operand): If character other than comma or newline is a
 453         logical end-of-line character, use the newline case.
 454         From Eric Youngdale:
 455         (operand): Set X_add_number field for floating-point numbers.
 456         (operand): Treat zero byte as end-of-operand.
 457
 458         * configure.in (per-target): Look for with_bfd_assembler option.
 459         For now, only accept "no", until the merge is done.
 460
 461         Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
 462         * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
 463           config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
 464         * read.c: Finish conversion to S_* macros in the VMS only
 465           parts of the program. Add "const" modifier to hex_value.
 466         * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
 467           "ifdef OBJ_VMS".
 468         * expr.c: Add "const" modifier to hex_value.
 469         * symbols.c: Finish conversion to S_* macros in the VMS only
 470           parts of the program.  Add "const" modifier to
 471           md_[long,short]_jump_size. Remove declaration of const_flag
 472           (which will be declared in obj-vms.h).
 473         * write.c: Add "const" modifier to md_[long,short]_jump_size.
 474           Fix arguments to VMS_write_object_file.
 475         * config-gas.com: New file.  Script for VMS systems to set up the
 476           configuration to build gas for VMS, and create config.status.
 477         * make-gas.com: Redone to work with new scheme.
 478         * obj-vms.c: Patch to fix bug where we were not correctly parsing the
 479           stabs directives.
 480         * obj-vms.c:  Define macros COPY_LONG and COPY_SHORT which
 481           will swap bytes if needed on a big endian system.  Use throughout
 482           as needed.
 483         * obj-vms.c (obj_aout_stab):  Add code to generate listing file.
 484         * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
 485           types of malformed stabs.  Change parsing algorithm so that we are
 486           more certain of having all of the information that we need on hand.
 487         * obj-vms.c (final_forward_reference):  New function, used to help
 488           resolve the data types of as many struct elements as possible
 489           when some part of the struct is not fully defined by the compiler.
 490         * obj-vms.c (VMS_LSYM_Parse):  Correctly handle case of continuation
 491           stabs directives.
 492         * obj-vms.c (VMS_write_object_file): Define all vtable psects
 493           as symbols as well in the object file.  Look for external functions
 494           that start with "__vt.", and turn them into variables, since the
 495           g++ compiler is incapable of doing this.
 496         * tc-vax.c: Add '1' option for backward compatibility with older GCC
 497           versions.
 498         * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
 499         * input-scrub.c (as_where): Fix bug where as would crash if we did not
 500           have the name of the source file yet.
 501         * config/ho-vms.h: define HO_VMS, not HO_VAX.
 502
 503 Mon Jan  4 05:17:26 1993  Ken Raeburn  (raeburn@cygnus.com)
 504
 505         * read.c (s_data): Always use "data_section", since it'll map to
 506         SEG_DATA or SEG_E1 if needed.
 507         (s_lcomm): Likewise with bss_section.
 508         (s_fill): Use memset, not bzero.
 509
 510 Thu Dec 31 04:29:27 1992  Ken Raeburn  (raeburn@kr-pc.cygnus.com)
 511
 512         * read.c: Deleted some code under "#ifdef DONTDEF" that was for

 514
 515         * config/obj-aout.h (segment_name): Delete definition.
 516         (seg_name): Delete declaration.
 517         * config/obj-bout.h (segment_name, seg_name): Ditto.

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

 576         * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.

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

 619         (do_scrub_next_char): For \", return " not '.
 620         (symbol_chars): Now const.
 621
 622         * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
 623         and "0b".  If LOCAL_LABELS_DOLLAR, check for "0$".
 624
 625         * config/obj-coff.h: Don't use #elif.
 626
 627         * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
 628         have it.  (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
 629
 630 Wed Dec 16 12:12:33 1992  Ian Lance Taylor  (ian@cygnus.com)

 647
 648         * listing.c: Call xmalloc, not malloc; don't declare malloc.

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

 837         putting them in the symbol table.
 838         * tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not
 839         M68KCOFF.
 840
 841         * obj-coffbfd.c (fill_section): set STYP_NOLOAD bit for .bss
 842         section.
 843
 844         * atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
 845         comment_chars, line_comment_chars and line_seperator_chars
 846         consistently const, and always initialized them.  Included read.h.

 856         * obj-coff.c (callj_table): Delete global variable.
 857         (obj_emit_relocations): Define it locally here, and only if
 858         TC_I960 is defined.
 859
 860         * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.
 861         (m68k_ip): Don't warn about bignum used as float bit-pattern.
 862
 863         * obj-coff.c: Replaced ANSI and non-ANSI function declarations
 864         with a single set using PARAMS macro.
 865
 866         * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length
 867         of 2.
 868
 869         * tc-i960.c: Missed a couple of 0->NO_RELOC conversions.
 870
 871         * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
 872         so widening works consistently.
 873
 874 Wed Oct 28 08:52:34 1992  Ken Raeburn  (raeburn@cygnus.com)
 875
 876         * version.c: Put conditional "const" before version_string, not
 877         before dummy function for VMS.  Now version 1.91.03.
 878
 879         * app.c (do_scrub_next_char): Need double-\ before `000' to show
 880         printed rep of null character.
 881
 882 Fri Oct 23 14:40:38 1992  Ian Lance Taylor  (ian@cygnus.com)
 883
 884         * obj-coffbfd.c (write_object_file): check return value of
 885         bfd_close_all_done.
 886
 887 Tue Oct 20 12:18:08 1992  Ian Lance Taylor  (ian@cygnus.com)
 888
 889         * Support for i386-sysv.
 890         obj-coffbfd.c (do_relocs_for, write_object_file): set segment
 891         addresses to reasonable sizes.  New define ZERO_BASED_SEGMENTS can
 892         be used to set them all to zero as was done before.
 893         (fill_section): segment addresses now set in write_object_file.
 894         (fill_section): Don't set STYP_NOLOAD for .bss section.
 895         (fixup_segment): 386 uses strange common symbol format.
 896         tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
 897         compatibility with SVR3.2 linker.

 904         * configure.in: differentiate between SunOS 4 and Solaris2 for Sun4
 905         hosts, use the sysv configuration for solaris2
 906
 907 Mon Oct  5 09:28:57 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
 908
 909          fix i960+non-bfd coff bit rot.
 910         * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
 911         support for C source listings. (obj_coff_endef): look in the right
 912         part of the symbol for the symbol name
 913
 914         * tc-m68k.c (get_num): make it work for all segments, not just the
 915         first three.
 916
 917 Mon Oct  5 03:30:36 1992  Mark Eichin  (eichin at tweedledumber.cygnus.com)

 926
 927         * obj-coffbfd.c (write_object_file): don't fixup for the z8k
 928         * tc-z8k.c: lots of bug fixes
 929
 930 Tue Sep 29 10:51:55 1992  Ian Lance Taylor  (ian@cygnus.com)
 931
 932         * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
 933         #elif, since it is not supported by old compilers.
 934         ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
 935         couple of expressions in tc-m68k.c.
 936
 937 Mon Sep 28 21:18:24 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 938
 939         * read.c (cons): If NO_RELOC is defined, use it.
 940
 941         * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
 942
 943 Fri Sep 25 18:18:52 1992  Ian Lance Taylor  (ian@cygnus.com)
 944
 945         * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
 946         local labels to start with a .) and set REGISTER_PREFIX to %.
 947         tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
 948
 949 Fri Sep 25 17:53:43 1992  John Gilmore  (gnu@cygnus.com)

 953 Fri Sep 25 14:12:58 1992  Ken Raeburn  (raeburn@kyriath.cygnus.com)
 954
 955         * as.h: Test if __STDC__ is defined only, don't test its value.
 956         * messages.c: If __STDC__ is not defined, define NO_STDARG.
 957
 958 Thu Sep 24 12:42:32 1992  Brendan Kehoe  (brendan@rtl.cygnus.com)
 959
 960         * listing.c (debugging_pseudo): Add stabs and stabn as things to
 961         ignore.
 962
 963 Tue Sep 22 13:02:07 1992  Sean Eric Fagan  (sef@cygnus.com)
 964
 965         * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
 966         sections starting from zero, rather than making them consecutive.
 967         This makes subsequent reloc calculations easier, esp if the object
 968         format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
 969         allocate lcomm in .data rather than in .bss.  It seems that some
 970         tools can't cope with a non-zero sized bss before linkage.
 971
 972 Tue Sep 22 15:10:51 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 973
 974         * tc-m68k.c: Replace "enum m68k_architecture" with "int"
 975         throughout.  That enum no longer means what we thought it meant.
 976
 977         * tc-m68k.c (md_assemble, md_parse_option): Handle new
 978         "-mno-688[58]1" options.
 979
 980         * tc-m68k.c: Added CPU32 support.

 982 Fri Sep 18 08:02:18 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
 983
 984         * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
 985
 986 Tue Sep 15 17:25:05 1992  Jim Wilson  (wilson@sphagnum.cygnus.com)
 987
 988         * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.

 991 Tue Sep 15 15:32:02 1992  Ian Lance Taylor  (ian@cygnus.com)
 992
 993         * Makefile.in (install): if $(tooldir) exists, install as in
 994         $(tooldir)/bin.
 995
 996 Sun Sep 13 20:30:10 1992  Ian Lance Taylor  (ian@cygnus.com)
 997
 998         * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
 999         .word is < -32768 or > 32767.  The -J flag causes the error to be
1000         ignored.  This is to catch over-sized switches generated by gcc on
1001         systems which don't support the broken .word hack.
1002         as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
1003         write.c (fixup_segment): check for signed .word overflow if
1004         WARN_SIGNED_OVERFLOW_WORD.
1005
1006         * write.c (fixup_segment): fixed missing parens in expression

1346
1347         * doc/Makefile.in: use m4 rather than gm4.
1348
1349 Mon May  4 18:56:19 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
1350
1351         * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
1352         calc the base of relocs correctly.
1353         * tc-a29k.c (parse_operand): allow expressions to be in any section.
1354
1355 Mon Apr 27 13:13:31 1992  K. Richard Pixley  (rich@cygnus.com)
1356
1357         * as.c, write.c: use -K rather than -k for the broken word warning
1358           option.
1359
1360 Tue Apr 21 13:35:30 1992  K. Richard Pixley  (rich@cygnus.com)

1363
1364 Wed Apr 15 21:19:31 1992  K. Richard Pixley  (rich@rtl.cygnus.com)
1365
1366         * Makefile.in: the tooldir copy of gas goes directly in tooldir.
1367
1368 Tue Apr 14 14:50:22 1992  Ken Raeburn  (Raeburn@Cygnus.COM)
1369
1370         * write.c (write_object_file): For b.out format, round up section
1371         start addresses to match required alignment.
1372
1373 Thu Apr  9 05:45:29 1992  Ken Raeburn  (Raeburn@Cygnus.COM)
1374
1375         * Makefile.in (install): Install into $(tooldir)/bin, since that's
1376         where gcc looks for it.
1377
1378 Tue Apr  7 15:12:15 1992  Sean Eric Fagan  (sef@cygnus.com)
1379
1380         * Makefile.in:  Changed some lines to be less confusing for some
1381         makes.
1382
1383         * input-file.c:  Conditionalize on _IOFBF, not VMS.
1384
1385         * read.c, write.c:  Change a series of ifdef/elif to
1386         ifdef/else/ifdef etc.
1387
1388 Fri Mar 27 12:21:16 1992  K. Richard Pixley  (rich@cygnus.com)
1389
1390         * symbols.c (fb_label_init): fix sizeof to memset.
1391
1392 Fri Mar 13 15:45:44 1992  K. Richard Pixley  (rich@cygnus.com)
1393
1394         * Makefile.in: install the man page.
1395
1396         * Makefile.in: pass down MAKEINFO explicitly on info.
1397
1398         * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
1399
1400 Fri Mar 13 08:03:03 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
1401
1402         * flonum-const.c: renamed flonum-konst.c to stop dos name
1403         conflict.
1404
1405 Thu Mar 12 04:42:38 1992  K. Richard Pixley  (rich@cygnus.com)
1406
1407         * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
1408           tc-m68k.h to te-sun3.h.
1409
1410 Wed Mar 11 23:32:42 1992  K. Richard Pixley  (rich@cygnus.com)
1411
1412         * configure.in: vxworks68 gets te-sun3.h.
1413
1414         * expr.c: remove limitation that local_labels_dollar or
1415           local_labels_fb must be < 10.
1416
1417         * symbols.c: remove local_labels_dollar, replace with a function
1418           interface for a sparse array.  All users adjusted.
1419
1420         * te-sun3.h: add LOCAL_LABELS_DOLLAR.
1421
1422 Sat Mar  7 00:06:25 1992  K. Richard Pixley  (rich@rtl.cygnus.com)
1423
1424         * doc/Makefile.in: commented out line for building as-all.texinfo.
1425           This is temporary.
1426
1427         * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
1428
1429 Fri Mar  6 21:57:18 1992  K. Richard Pixley  (rich@cygnus.com)
1430
1431         * Makefile.in: added check target.
1432
1433 Tue Mar  3 15:45:56 1992  K. Richard Pixley  (rich@rtl.cygnus.com)
1434
1435         * Makefile.in: added tooldir and program_prefix.
1436
1437 Sun Mar  1 04:43:19 1992  Michael Tiemann  (tiemann@cygnus.com)
1438
1439         * write.{c,h} (fix_new): Make these declarations consistent.
1440
1441 Sat Feb 29 13:59:10 1992  Michael Tiemann  (tiemann@cygnus.com)
1442
1443         * Makefile.in (strerror.o): Add rule so that broken Sun make can
1444         work in subdirs.
1445
1446 Wed Feb 26 19:26:28 1992  Steve Chamberlain  (sac at thepub.cygnus.com)
1447
1448         * read.c, obj-coffbfd.c : fix h8300 specific bit rot
1449
1450         * expr.c (operand): if can't work out what sort of operand it is,
1451         then look through FLT_CHARS for a hint.
1452
1453 Wed Feb 26 18:04:40 1992  K. Richard Pixley  (rich@cygnus.com)
1454
1455         * Makefile.in, configure.in: removed traces of namesubdir,
1456           -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
1457           copyrights to '92, changed some from Cygnus to FSF.
1458
1459         * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
1460           -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
1461           copyrights to '92, changed some from Cygnus to FSF.
1462
1463 Tue Feb 25 14:17:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
1464
1465         * expr.c: If an expression is single comma, then return with
1466         SEG_ABSENT rather than an error - since the sparc front end does
1467         really strange things with things like fbge,a
1468
1469         * as.h: include bfd.h if using many sections
1470         * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
1471         local labels didn't work.
1472         * listing.c (list_symbol_table): don't core dump when there's no
1473         symbol there.
1474         * write.c, write.h: call fix_new with the right number of args on
1475         the H8.
1476         * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
1477         errors nices
1478
1479 Sat Feb 22 12:26:28 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
1480
1481         * app.c: MRI compatibility - allow single quote to start a string.
1482         * as.c: fix typo recently introduced.
1483         * as.h : Don't include aout/reloc.h - it's not right for COFF!
1484         * expr.c: Much rewriting, to accomodate MRI syntax for
1485         expressions. Also easier to read now.
1486         * listing.c: Put back defuns
1487         * read.c: modified to accept MRI syntax, put back listing pseudo
1488         ops so that an assembler built with NO_LISTING ignores list ops
1489         rather than pukes.
1490         * write.c, write.h: fixs - only keep a reloc type in a fix if the target
1491         machine is a SPARC or a 29K.
1492         * config/obj-aout.c: added s_sect pseudo op
1493         * config/obj-coffbfd.c: lints, set the filehdr flags right and
1494         fill in the timestamp.
1495         * config/obj-coffbfd.h: Since we don't include aout/reloc.h
1496         anymore, define all the relocs which the tc-<x> bit will use so we
1497         can translate from them to the coff types.
1498         * config/tc-a29k.c: reloc_type isn't ane enum any more
1499         * config/tc-m68k.c: Added NO_RELOC definition.

1501 Fri Feb 21 06:21:07 1992  K. Richard Pixley  (rich@rtl.cygnus.com)
1502
1503         * Makefile.in: put header files before C source for TAGS; remove
1504           references to non-existent syscalls.h.
1505
1506         * read.c, write.c subsegs.c: back out the .bss changes.
1507
1508         * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
1509
1510         * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
1511
1512         * a.out.h: removed.
1513
1514 Fri Feb 21 01:08:48 1992  Minh Tran-Le (TRANLE@INTELLICORP.COM)
1515
1516         * symbols.c (local_label_name): symbols now start with ^A.
1517
1518         * read.c, subsegs.c, write.c obj-coff.c: added handling of
1519           `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
1520           generate these sections.  .align: will use NOP_OPCODE or 0
1521           for padding. This is just for being nice to the
1522           disassembler.
1523
1524         * expr.c (operand): changed to generate local label "\001L0"
1525           starting with a ^A so that it is recognized as a local label.
1526
1527         * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
1528
1529         * tc-i386.c: tc-i386.c: added handling of the following opcodes:
1530           i/o opcodes - inb, inw, outb and outw.  string manipulation with
1531           att syntax - scmp, slod, smov, ssca, ssto.
1532
1533         * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
1534           to just after .file .
1535
1536           In obj_crawl_symbol_chain() where it tries to put the external
1537           symbols apart, with the condition:
1538             (!S_IS_DEFINED(symbolP) &&
1539              !S_IS_DEBUG(symbolP) &&
1540              !SF_GET_STATICS(symbolP))
1541           it was moving too many symbols out. So I switch it back to the
1542           condition:
1543             (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
1544
1545           In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
1546           so that we don't use the F_RELFLG which make the linker complain
1547           that somebody has stripped the relocation info.
1548
1549           Also, the AIX ld program require that the relocation table
1550           is sorted by r_vaddr like the standard ATT assembler does.
1551
1552           [he also changed the sizeof(struct ...)'s into the coff
1553           style FOOSZ macros.  I'm not sure this is right, but I can't
1554           remember why.  xoxorich.]

1556 Fri Feb 21 01:08:48 1992  K. Richard Pixley  (rich@cygnus.com)
1557
1558         * Makefile.in, configure.in, doc: use the doc.  Build it, install
1559           it, clean it, etc.
1560
1561 Tue Feb 18 02:21:25 1992  K. Richard Pixley  (rich at cygnus.com)
1562
1563         * read.c: white space and comments only.
1564
1565         * configure.in: use the new atof-ns32.c for ns32k.
1566
1567         * write.c: comment change only.
1568
1569         * tc-m88k.[hc]: pulled in from hack's unfinished work.  These
1570           aren't yet integrated.
1571
1572         * tc-i860.[hc]: blew off the dust.  Something must still be done
1573           about conflicting relocation types.
1574
1575         * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
1576           real thing.
1577
1578         * tc-i960.c, tc-sparc.c: white space and comments only.
1579
1580         * tc-a29k.h: delete duplicate macro definition.
1581
1582         * new file atof-ns32k.c copied from hack's last unreleased gas.
1583
1584 Mon Feb 17 07:51:06 1992  K. Richard Pixley  (rich at cygnus.com)
1585
1586         * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
1587           rather than abort.
1588
1589         * nearly everything.  flush ChangeLog, package as gas-1.92.1.
1590           ChangeLog's prior to this are sketchy at best.  I have logs.
1591           They just aren't ChangeLogs.
