967 are also magic, and have special default flag settings.
968 (obj_elf_frob_symbol): Since the return value from this function
969 isn't used, don't bother calling obj_elf_write_symbol_p, since it
970 doesn't accomplish anything else.
972 * config/tc-sparc.c (md_section_align): Round up section size only
975 * symbols.c: Don't define DEBUG by default.
977 Thu Jul 22 12:09:41 1993 Ian Lance Taylor (ian@cygnus.com)

982 undefined_section for the return value.
984 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a

1002 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
1003 case to set obj_format=elf. Must go before i386-*-sysv* case that
1004 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
1005 *-*-solaris case, and move to before *-sysv* case that wants to
1006 set obj_format to coff.

1032 * Extensive changes to permit symbols to contain any expression
1033 type and to delay the computation of the expression until the
1034 value is actually needed. This permits setting symbols to values
1035 calculated based on object code size. Expressions were changed to
1036 no longer be in a section, to stop the overloading of segment and
1037 expression type that previously occurred.
1039 * as.c (big_section, pass1_section, diff_section, absent_section):
1041 (expr_section): Added (used for dummy symbols which hold

1125 (previous_section, previous_subsection): New vars.
1126 (obj_elf_section): Save current place in case DWARF code wants us
1127 to pop back to it. Handle unquoted section name as well as quoted
1128 section name. Don't crash on invalid strings.
1129 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
1132 * config/obj-elf.h: Don't include struc-symbol.h.

1241 sy_resolved and sy_resolving single bit fields.
1242 * symbols.c (symbol_new): Don't initialize sy_forward field.

2404 dropping a space immediately following an identifier.
2405 * expr.c, write.c: Rewrote assert expressions to not use multiple
2406 lines; I don't think that can be done portably.
2407 * config/tc-mips.c (macro): Use $AT if target register is zero in
2408 load instruction, which it can be for a floating point load.

2482 prototypes for all static functions. Moved existing minimal
2483 debugging format support info #ifndef OBJ_ECOFF blocks.

2532 * make-gas.com: Find obstack.obj if it's not in the current
2534 * read.c (s_ignore): Don't declare is_end_of_line. It's
2535 redundant, and triggers a VMS gcc compiler bug.
2537 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
2538 current segment as an argument. (Ignored in all cases but VMS.)
2539 All callers and definitions changed.

2856 (operand): Treat zero byte as end-of-operand.
2858 * configure.in (per-target): Look for with_bfd_assembler option.
2859 For now, only accept "no", until the merge is done.
2861 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
2862 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
2863 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
2864 * read.c: Finish conversion to S_* macros in the VMS only
2865 parts of the program. Add "const" modifier to hex_value.
2866 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
2868 * expr.c: Add "const" modifier to hex_value.
2869 * symbols.c: Finish conversion to S_* macros in the VMS only
2870 parts of the program. Add "const" modifier to
2871 md_[long,short]_jump_size. Remove declaration of const_flag
2872 (which will be declared in obj-vms.h).
2873 * write.c: Add "const" modifier to md_[long,short]_jump_size.
2874 Fix arguments to VMS_write_object_file.
2875 * config-gas.com: New file. Script for VMS systems to set up the
2876 configuration to build gas for VMS, and create config.status.
2877 * make-gas.com: Redone to work with new scheme.
2878 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
2880 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
2881 will swap bytes if needed on a big endian system. Use throughout
2883 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
2884 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
2885 types of malformed stabs. Change parsing algorithm so that we are
2886 more certain of having all of the information that we need on hand.
2887 * obj-vms.c (final_forward_reference): New function, used to help
2888 resolve the data types of as many struct elements as possible
2889 when some part of the struct is not fully defined by the compiler.
2890 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
2892 * obj-vms.c (VMS_write_object_file): Define all vtable psects
2893 as symbols as well in the object file. Look for external functions
2894 that start with "__vt.", and turn them into variables, since the
2895 g++ compiler is incapable of doing this.
2896 * tc-vax.c: Add '1' option for backward compatibility with older GCC
2898 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
2899 * input-scrub.c (as_where): Fix bug where as would crash if we did not
2900 have the name of the source file yet.
2901 * config/ho-vms.h: define HO_VMS, not HO_VAX.
2903 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
2905 * read.c (s_data): Always use "data_section", since it'll map to
2906 SEG_DATA or SEG_E1 if needed.
2907 (s_lcomm): Likewise with bss_section.
2908 (s_fill): Use memset, not bzero.
2910 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
2912 * read.c: Deleted some code under "#ifdef DONTDEF" that was for
2913 handling GDB symbol table data.
2915 * config/obj-aout.h (segment_name): Delete definition.
2916 (seg_name): Delete declaration.

2926 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
2927 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
2928 (segment_name) If BFD_ASSEMBLER, look up BFD section name;
2929 otherwise, use seg_name array.
2930 (seg_name): Declare only if not BFD_ASSEMBLER.
2931 (section_alignment): Declare only if not BFD_ASSEMBLER.
2932 (big_section, reg_section, pass1_section, diff_section,
2933 absent_section, text_section, data_section, bss_section): If
2934 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
2935 mapping to segT enum values.
2936 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
2937 if these are used or defined, if BFD_ASSEMBLER.
2938 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
2939 subseg_new split into two functions.
2940 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
2942 * as.h (volatile): Don't define if already defined.
2943 (had_errors, had_warnings): Provide prototypes for ANSI C even if
2945 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
2946 declare with format attribute for -Wformat checking.
2948 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2950 * app.c, config/tc-*.c: Don't include read.h, since it is already
2953 * These are based on patches from Minh Tran-le
2954 <mtranle@paris.intellicorp.com>.
2955 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
2956 obj_format coffbfd and gas_target i386coff for target.
2957 (i[34]86-*-isc*): New host (uses sysv).
2958 * config/i386aix.mt: Removed (no longer used).
2959 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2961 (LDFLAGS): Added, defined as -shlib.
2962 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2963 * config/te-sco386.h (LOCAL_LABEL): Don't define.
2964 (DOT_LABEL_PREFIX): Define.
2965 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
2966 name rather than L0\001.
2967 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
2969 * symbols.c, symbols.h (local_bss_counter): Removed.
2970 * write.c (write_object_file): bss no longer uses
2971 local_bss_counter. Pass correct data and bss size to
2972 VMS_write_object_file.

2977 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
2978 (size_section): Restored sanity check.
2979 (do_relocs_for): Base section address on s_paddr rather than
2980 computing it. Adjust a29k R_IHIHALF special case to account for
2981 section paddr (used to require paddr to be zero). If there are no
2982 reclos, set s_relptr to 0. Set relocation size in object_headers.
2983 (fill_section): Always set s_vaddr here, removing
2984 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
2985 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2986 Set STYP_INFO for .comment.
2987 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
2988 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

2990 H_{SET,GET}_* macros.
2991 (do_linenos_for): Set lineno size in object_headers.
2992 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2993 set s_vaddr here. If string_byte_count remains 4, set it back to
2994 0, and only write strings out if there are some. Call
2995 fill_section before do_relocs_for and do_linenos_for.
2996 (obj_coff_section): Handle optional quoted second argument giving
2997 section characteristics.
2998 (obj_coff_bss): Added to handle .bss.
2999 (obj_coff_ident): Added to handle .ident (puts string in .comment

3005 adjustment (already happened only for common symbols, but this is
3007 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
3008 * config/tc-i386.c (s_bss): Don't use if I386COFF.

3019 (do_scrub_next_char): For \", return " not '.
3020 (symbol_chars): Now const.
3022 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3023 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3025 * config/obj-coff.h: Don't use #elif.
3027 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3028 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

3054 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
3055 using ZERO_BASED_SEGMENTS.
3056 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
3057 never set segment address for SEG_E2 (.bss) and don't write out
3058 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3059 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3060 definitions, and don't merge tags with non-tags. Check for .bf
3061 rather than just checking whether the second character is b and
3062 the third character is f.
3063 (obj_coff_val): gcc can generate values which we don't handle
3064 correctly; discard information for now, since it only affects the
3065 debugging information.

3067 (yank_symbols): Don't merge labels.
3068 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3330 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
3332 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
3333 #elif, since it is not supported by old compilers.
3334 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
3335 couple of expressions in tc-m68k.c.
3337 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3339 * read.c (cons): If NO_RELOC is defined, use it.
3341 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
3343 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
3345 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
3346 local labels to start with a .) and set REGISTER_PREFIX to %.
3347 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
3349 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

3360 * listing.c (debugging_pseudo): Add stabs and stabn as things to
3363 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
3365 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
3366 sections starting from zero, rather than making them consecutive.
3367 This makes subsequent reloc calculations easier, esp if the object
3368 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
3369 allocate lcomm in .data rather than in .bss. It seems that some
3370 tools can't cope with a non-zero sized bss before linkage.
3372 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3374 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
3375 throughout. That enum no longer means what we thought it meant.

3378 "-mno-688[58]1" options.
3380 * tc-m68k.c: Added CPU32 support.

3393 * Makefile.in (install): if $(tooldir) exists, install as in
3396 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
3398 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
3399 .word is < -32768 or > 32767. The -J flag causes the error to be
3400 ignored. This is to catch over-sized switches generated by gcc on
3401 systems which don't support the broken .word hack.
3402 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
3403 write.c (fixup_segment): check for signed .word overflow if
3404 WARN_SIGNED_OVERFLOW_WORD.
3406 * write.c (fixup_segment): fixed missing parens in expression
3407 checking for byte or word overflow.
3409 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

3423 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
3425 * input-scrub.c (input_scrub_push): call input_file_begin, not
3427 messages.c (as_perror): print ": " between the passed in error and
3428 the strerror, like perror does.
3430 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

3433 From Steve Chamberlain:
3434 Makefile.in: Handle m68*-*-coff*.
3435 read.c, read.h: add mult argument to s_space
3437 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
3438 Motorola and MIT syntax; gas can now assemble either type of
3440 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

3446 (write_object_file) call fixup_mdeps
3447 (fixup_segment) set fx_subsy to 0.
3448 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
3450 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
3453 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3455 * Makefile.in (LIBS): Include opcode library.

3480 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3482 * config/tc-m68k.c (init_table): Now const. Always include 68851
3483 data, so that "bc" is available to 68040 cache instructions.
3484 Added "tt0", "tt1", and 68ec030 variants.
3485 (md_assemble): Complain if 68000 (only) and 68881 are specified.
3486 (enum _register): Added TT0, TT1.
3487 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
3488 line number correctly in "internal error" messages. Don't print
3489 architecture-mismatch message for operand errors.
3491 From Colin Smith (colin@wrs.com):
3492 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
3493 than install_operand.

3514 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
3515 has already been formatted (but may still contain %-characters).
3518 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
3520 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
3521 written with indirection on the last two operands, which can be
3522 either data or address registers. Added a new operand type 'r'
3523 which accepts either register type. Added '(' to notend stuff in
3524 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

3822 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3824 * doc/Makefile.in: commented out line for building as-all.texinfo.
3827 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
3829 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
3831 * Makefile.in: added check target.
3833 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3835 * Makefile.in: added tooldir and program_prefix.
3837 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
3839 * write.{c,h} (fix_new): Make these declarations consistent.
3841 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
3843 * Makefile.in (strerror.o): Add rule so that broken Sun make can
3846 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
3848 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
3850 * expr.c (operand): if can't work out what sort of operand it is,
3851 then look through FLT_CHARS for a hint.
3853 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
3855 * Makefile.in, configure.in: removed traces of namesubdir,
3856 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
3857 copyrights to '92, changed some from Cygnus to FSF.
3859 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
3860 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
3861 copyrights to '92, changed some from Cygnus to FSF.
3863 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3865 * expr.c: If an expression is single comma, then return with
3866 SEG_ABSENT rather than an error - since the sparc front end does
3867 really strange things with things like fbge,a
3869 * as.h: include bfd.h if using many sections
3870 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
3871 local labels didn't work.
3872 * listing.c (list_symbol_table): don't core dump when there's no
3874 * write.c, write.h: call fix_new with the right number of args on
3876 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
3879 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3881 * app.c: MRI compatibility - allow single quote to start a string.
3882 * as.c: fix typo recently introduced.
3883 * as.h : Don't include aout/reloc.h - it's not right for COFF!
3884 * expr.c: Much rewriting, to accomodate MRI syntax for
3885 expressions. Also easier to read now.
3886 * listing.c: Put back defuns
3887 * read.c: modified to accept MRI syntax, put back listing pseudo
3888 ops so that an assembler built with NO_LISTING ignores list ops
3890 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
3891 machine is a SPARC or a 29K.
3892 * config/obj-aout.c: added s_sect pseudo op
3893 * config/obj-coffbfd.c: lints, set the filehdr flags right and
3894 fill in the timestamp.
3895 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
3896 anymore, define all the relocs which the tc-<x> bit will use so we
3897 can translate from them to the coff types.
3898 * config/tc-a29k.c: reloc_type isn't ane enum any more
3899 * config/tc-m68k.c: Added NO_RELOC definition.
3901 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3903 * Makefile.in: put header files before C source for TAGS; remove
3904 references to non-existent syscalls.h.
3906 * read.c, write.c subsegs.c: back out the .bss changes.
3908 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
3910 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
3914 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
3916 * symbols.c (local_label_name): symbols now start with ^A.
3918 * read.c, subsegs.c, write.c obj-coff.c: added handling of
3919 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
3920 generate these sections. .align: will use NOP_OPCODE or 0
3921 for padding. This is just for being nice to the
3924 * expr.c (operand): changed to generate local label "\001L0"
3925 starting with a ^A so that it is recognized as a local label.
3927 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
3929 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
3930 i/o opcodes - inb, inw, outb and outw. string manipulation with
3931 att syntax - scmp, slod, smov, ssca, ssto.
3933 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
3934 to just after .file .
3936 In obj_crawl_symbol_chain() where it tries to put the external
3937 symbols apart, with the condition:
3938 (!S_IS_DEFINED(symbolP) &&
3939 !S_IS_DEBUG(symbolP) &&
3940 !SF_GET_STATICS(symbolP))
3941 it was moving too many symbols out. So I switch it back to the
3943 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3945 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3946 so that we don't use the F_RELFLG which make the linker complain
3947 that somebody has stripped the relocation info.
3949 Also, the AIX ld program require that the relocation table
3950 is sorted by r_vaddr like the standard ATT assembler does.
3952 [he also changed the sizeof(struct ...)'s into the coff
3953 style FOOSZ macros. I'm not sure this is right, but I can't
3954 remember why. xoxorich.]
3956 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
3958 * Makefile.in, configure.in, doc: use the doc. Build it, install
3961 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
3963 * read.c: white space and comments only.
3965 * configure.in: use the new atof-ns32.c for ns32k.
3967 * write.c: comment change only.
3969 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
3970 aren't yet integrated.
3972 * tc-i860.[hc]: blew off the dust. Something must still be done
3973 about conflicting relocation types.
3975 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3978 * tc-i960.c, tc-sparc.c: white space and comments only.
3980 * tc-a29k.h: delete duplicate macro definition.
3982 * new file atof-ns32k.c copied from hack's last unreleased gas.
3984 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3986 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3989 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3990 ChangeLog's prior to this are sketchy at best. I have logs.
3991 They just aren't ChangeLogs.
