[binutils-gdb.git] / gas / ChangeLog

Tue Mar 22 13:58:37 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

        * config/tc-mips.c (enum mips_pic_level): New enum.
        (mips_pic): Change from int to enum mips_pic_level.  Change all
        uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
        (load_address): Handle EMBEDDED_PIC.
        (macro): Handle EMBEDDED_PIC in all PIC cases.
        (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC.  If
        OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
        -non_shared to use NO_PIC (this is how the Irix 5 assembler
        works).  Do not permit -G with SVR4_PIC.
        (s_abicalls): Warn if -G was used, and force -G 0.
        (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
        anything but a.out, not just for ELF.  For ECOFF, don't generate a
        BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.

        * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.

Sun Mar 20 16:31:55 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)

        * config/tc-hppa.c (create_new_space): Use ints, not chars as
        parameters to avoid losing when compiling with HP CC.
        (create_new_subspace, update_subspace, fix_new_hppa): Likewise.

Sun Mar 20 14:43:14 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)

        * Makefile.in (config-stamp): If `defs' is defined, emit a
        preprocessor directive to create a macro named by this value into
        config.new; don't explicitly go for BFD_ASSEMBLER.
        * configure.in: Define `defs', not `BFDDEF'.  Set it to
        MANY_SEGMENTS for any obj-coffbfd target.
        * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
        * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
        or BFD_HEADERS.
        (LOCAL_LOADLIBES): Deleted.
        * config/m68kcoff.mt (TDEFINES): Don't define those macros.
        * config/m88kcoff.mt (TDEFINES): Ditto.
        * config/ebmon29k.mt: Deleted.
        * config/h8300hds.mt: Deleted.
        * config/ic960coff.mt: Deleted.
        * config/sparc.mt: Deleted.
        * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
        * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
        * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
        * config/z8k.mt (LOCAL_LOADLIBES): Deleted.
        (TDEFINES): Don't define the coffbfd macros.

        * Makefile.in: Insert makefile fragments before OBJS definition.
        (OBJS): Add $(TE_OBJS).

        * config/obj-coff.c (obj_pseudo_table): Supply "section"
        unconditionally.

        * write.c (set_symtab): Define only if BFD_ASSEMBLER.

Sun Mar 20 12:06:05 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)

        * Makefile.in (STAGESTUFF): Add gasp.new.

Fri Mar 18 20:09:16 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)

        * write.c (symbol_table_frozen): New variable, to be set after
        bfd_set_symtab is called.
        (dump_section_relocs): Note whether a symbol is a section symbol
        or not.
        (adjust_reloc_syms): For now, always supply an absolute symbol for
        fixups without symbols but not yet `done'.  Use section_symbol to
        get the symbol, instead of going directly for abs_symbol.
        (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
        reloc is not a section symbol and is not in the symbol table.
        (set_symtab): New function, broken out from write_object_file.
        Counts symbol table instead of relying on an earlier count.
        (write_object_file): Call set_symtab, but do it after potentially
        invoking the *_frob_file macros.  Don't bother counting symbols.
        Call symbol_remove, instead of expanding it in place.  Moved the
        conditionalized `object_file_size' declaration down to
        conditionalized block where it's used.  When using the absolute
        symbol for a fixup without a symbol, set sy_used_in_reloc.
        (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
        the correct symbol for the absolute section.

        * subsegs.c (section_symbol): Use symbol_new instead of
        symbol_make, since we may want it to go into the symbol table.
        Make the new symbol have internal linkage.  If
        obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
        symbol with the newly created GAS symbol.
        (obj_sec_sym_ok_for_reloc): Default to always returning 0.
        * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
        New macro.
        * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.

        * config/tc-sparc.c: Include subsegs.h.
        (in_signed_range): New function.
        (sparc_ip): Use it.
        (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
        (sparc_ip, label "immediate"): Reject constants for pcrel
        instructions only if the relocation type indicates a "call"
        instruction and the offset is within range of a "jmpl %g0".  If
        it's not in range, use the absolute section symbol plus an offset.
        (md_apply_fix): Use in_signed_range.  Combined _SPARC13 and
        _BASE13 cases.
        (tc_gen_reloc): Permit BFD_RELOC_SPARC13.

        * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
        MANY_SEGMENTS).

        * configure.in: Eliminated all targets using obj-coff but not
        defining BFD_ASSEMBLER; I think all such targets that are
        supported will be matched by real CPU-OS combinations earlier in
        the case statement.
        (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted.  Made
        some comments about the dpx2 configuration, but left it disabled,
        since it couldn't be reached before.
        (target a29k-amd-ebmonold): Deleted.

Thu Mar 17 13:36:09 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)

        * config/tc-hppa.c (pa_import): Correctly handle importing of an
        already defined symbol.

Wed Mar 16 17:11:37 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

        * config/tc-mips.c (mips_ip): Only accept overly large values for
        the 'j' operand if there are no further alternatives for this
        instruction.

        * config/obj-coffbfd.c (adjust_stab_section): Initialize
        stabstrseg to SEG_UNKNOWN, not -1.  After loop, check whether it
        is not SEG_UNKNOWN rather than checking whether it is >= 0.

        * config/tc-mips.c (mips_align): Take new argument, label, and use
        it instead of global insn_label.
        (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
        call to mips_emit_delay and pass it to mips_align.

Wed Mar 16 11:54:12 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)

        * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.

        * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
        argument to a .callinfo directive.  Don't loop forever on errors.

        * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
        use pre-defined registers as arguments.

Mon Mar 14 14:29:45 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)

        * write.c (write_object_file): Check both S_IS_LOCAL and
        S_IS_EXTERNAL when deciding whether to discard a symbol.

        * config-gas.com: Scan Makefile.in, not version.c, for current
        version number.  Delete all versions of temp files when finished
        with them.  Create config.h.

        * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
        values to reduce number of lookups with S_GET_VALUE.  Skip debug
        symbols to avoid "a really nasty bug".  (From Holger Teutsch,
        holger@botbso.rhein-main.de.)
        (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
        field.  (Also from Holger Teutsch.)  Watch for a would-be register
        mask that spans frags.

        * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
        this_base, not line_base.  (Patch from Andreas Arens,
        ari@obelix.av.rwth-aachen.de.)

        * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
        look local if they're exported or undefined.  Used to be done for
        i960 only.

        * read.c (s_lcomm, s_comm): Print symbol name being redefined.
        Get it from the looked-up symbol, instead of using the string from
        the input stream, which is no longer null-terminated.
        (LEX_PCT): New macro, defaults to 0.
        (lex_type): Use it for `%'.

        * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
        (vip_op): Now static, and returns void.  Callers changed.  Added
        forward decl.
        (vip): Ditto.  Call as_fatal directly if a program bug is
        detected.
        (op_hash): Let default initialization suffice.

        * Makefile.in (literal.o): Provide dependencies.

        * configure.in: Set new makefile variable OPCODES_LIB.
        * Makefile.in (LIBS): Use it.

        * Makefile.in (make-gas.com, stamp-mk.com): New targets.
        * vmsconf.sh: New file.
        * make-gas.com: Regenerated from new script.

        * configure.in (sparc*-*-lynxos*): Handle any version number
        suffix after "lynxos".  Set emulation to lynx.

        symbols.
        (ppc_is_toc_sym): Change .toc to .got.
        (md_apply_fix): Change handling of ELF relocs.
        (tc_gen_reloc): Likewise.

Fri Mar 11 17:42:20 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)

        * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
        0xffff for 'j' to be compatible with MIPS assembler.  These
        numbers are actually treated as negative.

        (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

        before indirecting through it.

        * ecoff.h, ecoff.c: New files pulled out of config/obj-ecoff.c to
        support generating ECOFF debugging information for MIPS ELF
        targets.  Compiled only if ECOFF_DEBUGGING is defined.  Changed
        handling of external symbols: it now always generates exactly
        those external symbols that are defined in the global symbol list.
        * Makefile.in (REAL_SOURCES): Added ecoff.c.
        (REAL_HEADERS): Added ecoff.h.
        (OBJS): Added ecoff.o.
        (ecoff.o): New target.

        (obj_ecoff_set_sym_index): Declare.

        * frags.h (frag_grow): Declare.
        * frags.c (frag_grow): Made non-static.

        * write.c (is_dnrange): Do not define if md_relax_frag is defined.
        (relax_segment): If md_relax_frag is defined, use it to handle a
        frag of type rs_machine_dependent rather than looking through
        md_relax_table.

        * read.c (read_a_source_file): If we find a bad pseudo-op,
        do a continue to go on to the next line rather than a break.
        Removed duplicate bad pseudo-op code which was never executed.

        * read.c (s_lcomm): Do not require a comma after the name.

        * write.c (relax_and_size_seg): Don't set SEC_HAS_CONTENTS for a
        bss section.  Set SEC_RELOC if there are any relocations, even for
        a zero size section.

        * write.c (write_relocs): In RELOC_EXPANSION_POSSIBLE case, base
        data offset on reloc[0]->address rather than reloc[j]->address, so
        that multiple relocs can affect different memory locations.

        * write.c (chain_frchains_together, relax_and_size_seg,
        adjust_reloc_syms, write_relocs): Make third argument PTR, not
        char *, to match definition of bfd_map_over_sections.

        * app.c (do_scrub_next_char): Don't interpret a comment character
        as starting a CPP line directive unless it is a '#' and is the
        very first characters on the line (i.e., do not permit leading
        whitespace).

        * messages.c (identify): Make file argument non-const, to match
        callers.

        (tc_gen_reloc): For SOM PLABELs, always set addend to zero for now.
        (md_apply_fix_1): Do not call hppa_field_adjust for any PLABEL
        field.

        ANSI-C features.

        * config/tc-hppa.c (pa_type_args): Renamed from pa_export_args.
        Accept new argument "is_export".  All callers changed.  When
        processing a .export directive for a function, do not allow
        the user to set the type to "CODE", instead warn and set the
        type to "ENTRY".

Mon Nov  8 12:05:07 1993  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

        * config/tc-mips.c (mips_ip, printInsn): Handle 'k' (from Ted

                        Recognise unixware if the user supplies it.

Sun Nov  7 01:02:08 1993  Jeffrey A. Law  (law@snake.cs.utah.edu)

        * First cut at cleaning up PA instruction parsing.
        * config/tc-hppa.c (pa_get_absolute_expression): Accept pointer to
        insn structure as an argument, and a pointer to a string.  All
        callers changed.  Always read any field selector here.  Call
        evaluate absolute to get a return value.
        (evaluate_absolute): Addept pointer to insn structure as its
        argument.  All callers changed.

        into an instruction and continuing the main pa_ip loop.
        (CHECK_FIELD): New macro for simple range checking of fields.
        (pa_ip): Delete unused variables.  Use INSERT_FIELD_AND_CONTINUE
        and CHECK_FIELD.  All immediate fields now pass through
        pa_get_absolute_expression which will also handle field selectors.
        Delete dead code.  Simplify.
        (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
        applied are in range.  Use bfd_put_32 rather than inserting each
        byte of the fixed instrution into the buffer ourselves.

        * write.c (fixup_segment): Delete {SEG,GLOBAL}_DIFF_ALLOWED code,
        it was PA specific and is no longer needed (it's now handled 
        within the PA backend).
        * config/tc-hppa.h (SEG_DIFF_ALLOWED): Delete definition.
        * config/tc-hppa.c (fix_new_hppa): If the subtract symbol for
        a fixup is $global$ change it to NULL as $global$ is really only
        needed long enough to determine the base type of relocation to use.

        * config/tc-hppa.c (create_new_subspace): Initialize subspace_defined.

        * config/tc-hppa.c (pa-ip, case 'z'): Make field selectors work

        pc-relative addressing even if pc-relative flag is already set.

        * config/tc-m68k.c (m68k_ip_op): Use strchr, not index.  Don't
        declare either.

        * doc/Makefile.in (distclean): Delete intermediate files from dvi
        build, but not the dvi or info files.
        * Makefile.in (clean-here): New target; cleans up current
        directory only.
        (distclean): Use it instead of clean.

        * read.c (s_xstab): Don't use alloca.

        * messages.c (identify): New routine; print message identifying
        following messages as coming from assembler.
        (as_show_where, as_bad_internal, as_bad_where): Call it.

        predefined register table.
        (pa_parse_number): Handle %rp in common register shortcut code.
        Consistently set return value to -1 for an error.  Clean up error
        messages and only print them when "print_errors" is true.  Handle
        empty string case like the HP assembler -- assume a value of
        zero.
 
        * config/ho-hpux.h: Do not include ho-sysv.h.  Instead include
        standard hpux include files to pick up various function decls.

        * config/ho-hppaosf.h: Delete _IO* macros.  They are defined in
        stdio.h.  Delete bogus declaration of free.  Get path to
        alloca-conf.h right.

Tue Nov  2 13:57:30 1993  Ken Raeburn  (raeburn@rover.cygnus.com)

        * expr.c (operand): Fix checks for characters following "0b" or

        descriptor information to the BFD symbol.
        (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",
        they are simply markers.  Make R_HPPA_UNWIND_* handling OBJ_ELF
        dependent.
        (pa_build_unwind_subspace): Whole function is OBJ_ELF dependent.
        (pa_entry): Build a R_HPPA_ENTRY relocation when configured for SOM.
        (pa_exit): Likewise, but built a R_HPPA_EXIT relocation.  Do not
        build "end-of-function" symbols for SOM, they are not needed.

        * config/tc-hppa.c (process_exit): Create temporary symbols with
        correct prefixes so they can be eliminated later.

        * config/tc-hppa.c (call_info struct): Delete unused "frame" field.
        (pa_callinfo): Insert framesize into the unwind information as 
        soon as it's available.
        (pa_build_unwind_subspace): Do not insert framesize into the unwind
        information here.

        * Add support for marker type relocations.  These mark areas
        of interest to the linker.  ENTRY/EXIT relocations for SOM are
        an example of marker relocations.
        * write.c (write_relocs): Instead of assuming size of a relocation
        is 4 bytes, pick up the size from relocation itself.
        (fixup_segment): Do not complain that a value is too small for 
        marker relocations.

        Ignore .bgnb and .endb.
        (gp_reference): _gp_disp is never addressed off GP.
        (macro_build): Ignore macros while searching for insn.  For cases
        i, j, and o, accept the reloc type as an argument rather than
        assuming BFD_RELOC_LO16.  Don't try to convert BFD_RELOC_LO16 to
        BFD_RELOC_MIPS_GPREL.  Added new case a.
        (set_at, load_register, macro): Changed calls to macro_build to
        pass new argument for i, j and o cases.
        (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A.  These require
        special handling when generating SVR4 PIC code.
        (mips_ip, tc_get_register, s_frame): Use macros FP, SP, GP and AT
        rather than hard coded constants.
        (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and
        BFD_RELOC_MIPS_CALL16.
        (s_option): Set mips_pic based on .option picN.
        (s_abicalls): New function; set mips_pic to 2.
        (s_cpload): New function; handle .cpload.

        * config/obj-ecoff.c (obj_pseudo_table): Add entries for .bgnb,
        .endb and .verstamp, setting them to s_ignore.

        field.  Define SUBSPACE_DEFINED accessor macro.
        (pa_subspace): Allow user to override subspace attributes for
        built-in subspaces.  Set ssd_defined at the end of fcn -- that
        way the attributes can only be changed once.  Pass newly allocated
        name to is_defined_subspace, not a pointer to the input line.
        Fix typo in space/subspace rework.
        (is_defined_subspace): Delete unused 2nd arg.  All callers changed.

        * config/tc-hppa.c (pa_import): If currently in the text segment

        symbol types which can be set from an IMPORT/EXPORT statement.
        (pa_export_args): Set the pa_symbol_type type based on arguments.

        * Allow backends to override the value of the fake label.
        * write.h (LOCAL_LABEL): Delete DOT_LABEL_PREFIX code.  Instead
        assume backends will define LOCAL_LABEL if anything other than
        'L' is used to denote a local label.
        (FAKE_LABEL_NAME): New macro.  Defines the default name used for
        the "fake" label.
        * expr.c (make_expr_symbol): Delete DOT_LABEL_PREFIX code
        and instead simply use the string defined by FAKE_LABEL_NAME.

        * read.c (s_stab_generic): Likewise.
        * config/tc-hppa.h (FAKE_LABEL_NAME): Define as L$0\001 so it's
        known to be a local label.
        * config/tc-i386.h (DOT_LABEL_PREFIX): Delete.
        (LOCAL_LABEL, FAKE_LABEL_NAME): Define.
        * config/tc-m68k.h (DOT_LABEL_PREFIX): Delete.

        (pa_subspace): Use current_space rather than a lookup via 
        pa_segment_to_space.  Reset BFD section flags as required by 
        the .subspace directive.  Likewise for the section alignment.
        Pass the current space to update_subspace and create_new_subspace.
        (pa_spaces_begin): Only use space/subspace aliases if USE_ALIASES
        is true.  When not using aliases, create a BFD section for each
        subspace encountered.  When not using aliases replace the default
        text, data, and bss segments with new ones.
        (create_new_subspace): When not using aliases each subspace has a 
        section/segment and subsegments are not needed, so set the subsegment
        to zero. 

        * config/tc-hppa.c (pa_parse_space_stmt): If needed, call
        obj_set_section_attributes to pass space attributes to the 
        BFD backend.
        (create_new_space): Likewise.

        SOM relocations.

        * config/tc-hppa.c (pa_comm): Delete incorrect check for symbol

        directive which does not define a "well-known" space and does
        not include a space number as an argument.
        
        * config/tc-hppa.c (pa_def_subspaces): Correct initialization of the
        "defined", "loadable", "code_only" and "space_index" fields.

        (MAX_RELOC_EXPANSION): Likewise.

        * config/tc-hppa.c (log2): Renamed from is_power_of_2.  Fix all
        callers. Now returns log2 (N) for positive N which are an exact
        power of two or -1 for an error.

        * config/tc-hppa.c (pa_callinfo): Range check values provided for

        * config/tc-a29k.c (md_begin): When opcodes are mashed together in
        the table, require that the one without bit 0x1000000 set come
        first.  Require further that it be case 'b' or 'P'.  The a29k
        opcode table already meets these constraints.
        (machine_ip): When handling case 'i' or 'A', make sure that the
        appropriate opcode really exists by looking at the next entry in
        the opcode table.

Wed Oct 27 11:48:56 1993  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

        * config/tc-m68k.c (m68k_ip): Adjust offsets for PC relative

Mon Oct 25 10:20:31 1993  Ken Raeburn  (raeburn@rover.cygnus.com)

        * doc/Makefile.in (install-info): Use "$<*" so VPATH will find
        as.info* even if they're in $(srcdir) (e.g., for FSF
        distributions).

        * write.c (write_relocs): For relocs that are pc_relative and

        (as_where): Return current file name and line number, don't print
        them out.

        OPTIONAL_REGISTER_PREFIX if either is already defined.

        * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".

        * configure.in: Set bfd_gas for all sparc targets.  Added facility
        for keeping or rejecting configurations still under development;
        default is to assume production environment, and reject configs
        still being worked on.  Mark Elf configurations (except sparc and
        i386) as developmental.  Deleted cases matching some generic names
        in favor of more specific names.  (E.g., when we get Alpha
        support, we'll still only support VMS for Vax.)

        * config/tc-sparc.h (md_end): New macro.
        * config/tc-sparc.c (md_end): Function deleted.
        (BFD_RELOC_*): Delete macros that used to help keep the non-bfd
        version compiling.  All sparc targets will use bfd now.
        * tc.h (md_end): Don't declare if it's defined as a macro.

        Changes from Jeff Law and Peter Hoogenboom:

        * read.c (next_char_of_string): Limit octal character constants to
        three digits.

        * config/tc-hppa.h: Major cleanup.  Use GNU-style comments.  Warn
        against placing additional object-file dependent code here.  Warn
        against contaminating all of GAS with the internals of tc-hppa.c
        through inclusion of tc-hppa.h.  Delete all forward declarations
        for functions only used within tc-hppa.c, likewise for structures,
        variables, and #defines.  Try to group OBJ_ELF and OBJ_SOM
        conditional code in a few small places.

        * config/tc-hppa.c: Major cleanup.  Use GNU-style comments.  Group
        structures, global variables, forward declarations together.
        Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
        conditional code -- try to group conditional code together
        into a few places.   Make all functions and variables which
        are only used within tc-hppa.c static.  PARAMize all functions.
        Add comments to functions.  Delete unused functions, variables,
        #defines, etc.  Delete unused members within structures.  Delete
        ldil;ble hacks -- it is believed they were installed to work
        around old gas bugs.   Avoid using mixed case for local
        functions, variables, and structures.  Fix formatting problems
        not found by GNU-indent.  Add FIXME notices for things which
        should be worked on the near future.  Delete lots of old
        useless (1.36 PA-SOM) code.  

        * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
        field of the fixS structure.  Needed to build unwind
        descriptors correctly.

        * write.c: (fixup_segment): Allow expressions such as
        sym1-sym2+const as long as sym2 is $global$.

        * write.c (adjust_reloc_syms): Provide a hook so that a target
        cpu configuration can reject certain relocation reductions.
        * tc-hppa.h (tc_fix_adjustable): New macro.  Only accept relocations
        which do not involve function symbols.

        * config/tc-hppa.h: Reindent with GNU-indent.  Delete references
        to OBJ_OSFROSE.  Fix typos (OBJ_SOME -> OBJ_SOM).  Delete unused
        STAB_FIXUP macro.
        * config/tc-hppa.c: Likewise.

        * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
        of elf32_symbol_type.
        (pa_export_args): Likewise.
        (elf_hppa_final_processing): Likewise.
        (pa_desc): Do not call obj_elf_desc.  (Is pa_desc even needed
        anymore?)
        (hppa_tc_make_sections): Do not declare elf_get_symtab_map any
        ore.

        * config/tc-hppa.c: (md_section_align): Align all sections to
        a multiple of the section alignment rather than always a
        multiple of 8.

        * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
        bits are zero (eg they specify no relocations), then do not even
        bother adding their entries to thesymextn section.

Thu Oct 21 15:44:55 1993  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

        * config/tc-sparc.c (md_parse_option): Accept and ignore -sparc

        characters in state 6.
        * read.c (next_char_of_string): Accept \Xh* and \xh* where h* are
        hexidecimal digits.

        * config/tc-i386.c (md_apply_fix_1): Make cross segment calls work
        for ELF by hacking around bizarre bfd_perform_relocation behaviour
        that I don't dare change.

Thu Oct 14 11:33:25 1993  Michael Meissner  (meissner@osf.org)

        * config/tc-i386.c: (md_begin): Do not zero static arrays.  Don't
        call strchr for each character to see if it is a special char,
        instead add a second loop over special_chars.  Set alignment
        of text, data and bss sections to 4.
        (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
        used again.
        (reloc): Don't return 8 and 16 bit non-PC relative relocations on
        ELF, since the ELF object format does not have these type of
        relocations.  Change the abort into as as_bad and return
        BFD_RELOC_NONE to silence compiler warnings.
        (md_assemble): Keep track of the instruction size.  Allow white
        space between the $ and the constant for compatibility with older
        gases and other assemblers.
        (i386_operand): Skip spaces between $ and expression.
        (tc_gen_reloc): Don't allow anything but 32 bit relocations on
        ELF.  Convert abort into an as_bad and assert into as_fatal.

Wed Oct 13 16:50:55 1993  Ken Raeburn  (raeburn@cambridge.cygnus.com)

        * config/obj-coffbfd.c (fixup_segment) [DIFF_EXPR_OK]: If

        * config/obj-ecoff.c (ecoff_build_symbols): Handle st_End symbol
        for st_StaticProc just like st_Proc.

        * write.c (relax_and_size_all_segments): Moved #endif for OBJ_BOUT
        so that OBJ_BOUT doesn't forget to adjust all the fragments in the

        (obj_elf_frob_symbol): Since the return value from this function
        isn't used, don't bother calling obj_elf_write_symbol_p, since it

        * Extensive changes to permit symbols to contain any expression
        type and to delay the computation of the expression until the
        value is actually needed.  This permits setting symbols to values
        calculated based on object code size.  Expressions were changed to
        no longer be in a section, to stop the overloading of segment and
        expression type that previously occurred.

        * read.c (read_begin): Call obstack_begin with values closer to 1K
        multiples.
        (read_a_source_file, big_cons, float_cons): Use memcpy instead of

        * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when

        undefined symbols.

        * read.c (s_data), config/obj-coffbfd.c (obj_coff_data): If -R,

        * config/tc-hppa.h (tc_frob_label): Define.

        * config/tc-mips.c: Many changes to support simple assembler
        optimization.

        (md_atof): Handle floating point numbers correctly for both
        big and little endian targets.
        (s_align, s_cons): Call mips_align rather than frag_align.

        * config/obj-coffbfd.c (fixup_segment): If TC_M88K, don't adjust

        file).
        * config/tc-m88k.c (md_pcrel_from): Corrected return value.
        (omagic): Removed unused variable.

        * Preliminary support for m88k-coff.

        * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
        a29k .bss section; the mondfe program doesn't like it.

        process relocs if there aren't any relocs to process.  Avoids
        malloc/free bug on SCO too.

        * as.h: Move local include files below system include files, to
        avoid some redefinition complaints on some systems.
        (const, volatile): Don't need these conditionally defined if we
        use CONST and VOLATILE from ansidecl.h.
        (seg_name): Use CONST, not const.

        * Makefile.in: add dvi target; as-$(config).texinfo might live in
        srcdir, might be in objdir.

        dropping a space immediately following an identifier.

        debugging format support info #ifndef OBJ_ECOFF blocks.

        directory.
        * read.c (s_ignore): Don't declare is_end_of_line.  It's
        redundant, and triggers a VMS gcc compiler bug.

        * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
        current segment as an argument.  (Ignored in all cases but VMS.)
        All callers and definitions changed.

Tue Mar  2 11:56:19 1993  Ian Lance Taylor  (ian@cygnus.com)

        * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING
        case compile again.

Tue Mar  2 08:53:34 1993  Ken Raeburn  (raeburn@cygnus.com)

        * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,
        so "~0x80" won't be rejected.

        * config/obj-elf.c: No longer include elf/reloc.h.
        (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
        (obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out
        routines.
        (obj_elf_xstab): New routine.
        (obj_elf_set_size): Call as_warn, not fprintf.  Pass desired
        argument to s_ignore.  Put "#if 0" around unused code.
        (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
        Call elf_xstabs for .stabs and .xstabs operators.

        * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".

        * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
        present.

        * configure.in: mips-bsd configuration was missing format spec.
        Should use aout.

        * Makefile.in (Makefile): Depends on configure.in.

        * config/tc-mips.c (append_insn): Don't check for alignment of
        frag in memory; alignment of instructions in section is a separate
        matter.

        * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
        C availability.

        * listing.h: Always provide function declarations, not macros, so
        pcc won't lose.

        "IGNORE_DEBUG" conditional, since both branches are identical.
        Use S_SET_TYPE, S_GET_TYPE, and S_GET_DESC instead of directly
        referencing symbol structure members.

        (subseg_new) [BFD_ASSEMBLER]: Rewritten to change to new section,
        given section name and subseg number.
        (subseg_set) [BFD_ASSEMBLER]: New function; change to a possibly
        new section/subsection.

        * read.c: Don't include ctype.h.
        (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
        for now; should be machine-dependent.

        (fix_new): Initialize fx_addnumber.

        * listing.c: Don't include target-cpu.h explicitly, since as.h

        * expr.c (operand): If character other than comma or newline is a
        logical end-of-line character, use the newline case.
        From Eric Youngdale:
        (operand): Set X_add_number field for floating-point numbers.
        (operand): Treat zero byte as end-of-operand.

        * configure.in (per-target): Look for with_bfd_assembler option.
        For now, only accept "no", until the merge is done.

        Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
        * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
          config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
        * read.c: Finish conversion to S_* macros in the VMS only
          parts of the program. Add "const" modifier to hex_value.
        * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
          "ifdef OBJ_VMS".
        * expr.c: Add "const" modifier to hex_value.
        * symbols.c: Finish conversion to S_* macros in the VMS only
          parts of the program.  Add "const" modifier to
          md_[long,short]_jump_size. Remove declaration of const_flag
          (which will be declared in obj-vms.h).
        * write.c: Add "const" modifier to md_[long,short]_jump_size.
          Fix arguments to VMS_write_object_file.
        * config-gas.com: New file.  Script for VMS systems to set up the
          configuration to build gas for VMS, and create config.status.
        * make-gas.com: Redone to work with new scheme.
        * obj-vms.c: Patch to fix bug where we were not correctly parsing the
          stabs directives.
        * obj-vms.c:  Define macros COPY_LONG and COPY_SHORT which
          will swap bytes if needed on a big endian system.  Use throughout
          as needed.
        * obj-vms.c (obj_aout_stab):  Add code to generate listing file.
        * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
          types of malformed stabs.  Change parsing algorithm so that we are
          more certain of having all of the information that we need on hand.
        * obj-vms.c (final_forward_reference):  New function, used to help
          resolve the data types of as many struct elements as possible
          when some part of the struct is not fully defined by the compiler.
        * obj-vms.c (VMS_LSYM_Parse):  Correctly handle case of continuation
          stabs directives.
        * obj-vms.c (VMS_write_object_file): Define all vtable psects
          as symbols as well in the object file.  Look for external functions
          that start with "__vt.", and turn them into variables, since the
          g++ compiler is incapable of doing this.
        * tc-vax.c: Add '1' option for backward compatibility with older GCC
          versions.
        * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

          have the name of the source file yet.
        * config/ho-vms.h: define HO_VMS, not HO_VAX.

Mon Jan  4 05:17:26 1993  Ken Raeburn  (raeburn@cygnus.com)

        SEG_DATA or SEG_E1 if needed.
        (s_lcomm): Likewise with bss_section.
        (s_fill): Use memset, not bzero.

        absent_section, text_section, data_section, bss_section): If
        BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
        mapping to segT enum values.
        (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
        if these are used or defined, if BFD_ASSEMBLER.

        NO_STDARG.
        (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
        declare with format attribute for -Wformat checking.

Wed Dec 30 10:18:57 1992  Ian Lance Taylor  (ian@cygnus.com)

        * app.c, config/tc-*.c: Don't include read.h, since it is already
        included by as.h.

        * These are based on patches from Minh Tran-le
        <mtranle@paris.intellicorp.com>.
        * configure.in (i[34]86-ibm-aix*): Accept i486 for host.  Use
        obj_format coffbfd and gas_target i386coff for target.
        (i[34]86-*-isc*): New host (uses sysv).
        * config/i386aix.mt: Removed (no longer used).
        * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
        (MINUS_G): Removed.
        (LDFLAGS): Added, defined as -shlib.
        * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
        * config/te-sco386.h (LOCAL_LABEL): Don't define.
        (DOT_LABEL_PREFIX): Define.
        * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
        name rather than L0\001.
        * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
        local_bss_counter.
        * symbols.c, symbols.h (local_bss_counter): Removed.
        * write.c (write_object_file): bss no longer uses
        local_bss_counter.  Pass correct data and bss size to
        VMS_write_object_file.
        * config/obj-vms.c (VMS_write_object_file): Accept bss size as
        argument, rather than using local_bss_counter.

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

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

        * app.c (app_push): Use memcpy, not bcopy.
        (do_scrub_next_char): For \", return " not '.
        (symbol_chars): Now const.

        * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
        and "0b".  If LOCAL_LABELS_DOLLAR, check for "0$".

        * config/obj-coff.h: Don't use #elif.

        * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
        have it.  (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

Wed Dec 16 12:12:33 1992  Ian Lance Taylor  (ian@cygnus.com)

        * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

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

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

        * subsegs.h: add extern to segment_info declaration.

        * read.h: added extern declarations for comment_chars,

        read.c, app.c: removed definitions of comment_chars,
        line_comment_chars, and line_separator_chars.

        * tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
        still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
        the register name.

        be used to set them all to zero as was done before.
        (fill_section): segment addresses now set in write_object_file.
        (fill_section): Don't set STYP_NOLOAD for .bss section.

        * tc-z8k.c: lots of bug fixes

Tue Sep 29 10:51:55 1992  Ian Lance Taylor  (ian@cygnus.com)

        * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
        #elif, since it is not supported by old compilers.
        ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
        couple of expressions in tc-m68k.c.

Mon Sep 28 21:18:24 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)

        * read.c (cons): If NO_RELOC is defined, use it.

Fri Sep 25 18:18:52 1992  Ian Lance Taylor  (ian@cygnus.com)

        * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
        local labels to start with a .) and set REGISTER_PREFIX to %.
        tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

Fri Sep 25 17:53:43 1992  John Gilmore  (gnu@cygnus.com)

        ignore.

Tue Sep 22 13:02:07 1992  Sean Eric Fagan  (sef@cygnus.com)

        * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
        sections starting from zero, rather than making them consecutive.
        This makes subsequent reloc calculations easier, esp if the object
        format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
        allocate lcomm in .data rather than in .bss.  It seems that some
        tools can't cope with a non-zero sized bss before linkage.

Tue Sep 22 15:10:51 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)

Sat Feb 29 13:59:10 1992  Michael Tiemann  (tiemann@cygnus.com)

        * Makefile.in (strerror.o): Add rule so that broken Sun make can
        work in subdirs.

Wed Feb 26 19:26:28 1992  Steve Chamberlain  (sac at thepub.cygnus.com)

        * read.c, obj-coffbfd.c : fix h8300 specific bit rot

        * expr.c (operand): if can't work out what sort of operand it is,
        then look through FLT_CHARS for a hint.

Wed Feb 26 18:04:40 1992  K. Richard Pixley  (rich@cygnus.com)

        * Makefile.in, configure.in: removed traces of namesubdir,
          -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
          copyrights to '92, changed some from Cygnus to FSF.

        * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
          -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
          copyrights to '92, changed some from Cygnus to FSF.

        * expr.c: If an expression is single comma, then return with
        SEG_ABSENT rather than an error - since the sparc front end does
        really strange things with things like fbge,a

        * as.h: include bfd.h if using many sections
        * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
        local labels didn't work.
        * listing.c (list_symbol_table): don't core dump when there's no
        symbol there.
        * write.c, write.h: call fix_new with the right number of args on
        the H8.
        * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
        errors nices

Sat Feb 22 12:26:28 1992  Steve Chamberlain  (sac at rtl.cygnus.com)

        * app.c: MRI compatibility - allow single quote to start a string.
        * as.c: fix typo recently introduced.
        * as.h : Don't include aout/reloc.h - it's not right for COFF!
        * expr.c: Much rewriting, to accomodate MRI syntax for
        expressions. Also easier to read now.
        * listing.c: Put back defuns
        * read.c: modified to accept MRI syntax, put back listing pseudo
        ops so that an assembler built with NO_LISTING ignores list ops
        rather than pukes.
        * write.c, write.h: fixs - only keep a reloc type in a fix if the target
        machine is a SPARC or a 29K.
        * config/obj-aout.c: added s_sect pseudo op
        * config/obj-coffbfd.c: lints, set the filehdr flags right and
        fill in the timestamp.
        * config/obj-coffbfd.h: Since we don't include aout/reloc.h
        anymore, define all the relocs which the tc-<x> bit will use so we
        can translate from them to the coff types.
        * config/tc-a29k.c: reloc_type isn't ane enum any more
        * config/tc-m68k.c: Added NO_RELOC definition.

Fri Feb 21 06:21:07 1992  K. Richard Pixley  (rich@rtl.cygnus.com)

        * Makefile.in: put header files before C source for TAGS; remove
          references to non-existent syscalls.h.

        * read.c, write.c subsegs.c: back out the .bss changes.

        * obj-aout.c: do not include stab.gnu.h if NO_LISTING.

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

        * a.out.h: removed.

Fri Feb 21 01:08:48 1992  Minh Tran-Le (TRANLE@INTELLICORP.COM)

        * symbols.c (local_label_name): symbols now start with ^A.

        * read.c, subsegs.c, write.c obj-coff.c: added handling of
          `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
          generate these sections.  .align: will use NOP_OPCODE or 0
          for padding. This is just for being nice to the
          disassembler.

        * expr.c (operand): changed to generate local label "\001L0"
          starting with a ^A so that it is recognized as a local label.

        * as.c (perform_an_assembly_pass): zero bss_fix_root, too.

        * tc-i386.c: tc-i386.c: added handling of the following opcodes:
          i/o opcodes - inb, inw, outb and outw.  string manipulation with
          att syntax - scmp, slod, smov, ssca, ssto.

        * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
          to just after .file .

          In obj_crawl_symbol_chain() where it tries to put the external
          symbols apart, with the condition:
            (!S_IS_DEFINED(symbolP) &&
             !S_IS_DEBUG(symbolP) &&
             !SF_GET_STATICS(symbolP))
          it was moving too many symbols out. So I switch it back to the
          condition:
            (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))

          In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
          so that we don't use the F_RELFLG which make the linker complain
          that somebody has stripped the relocation info.

          Also, the AIX ld program require that the relocation table
          is sorted by r_vaddr like the standard ATT assembler does.

          [he also changed the sizeof(struct ...)'s into the coff
          style FOOSZ macros.  I'm not sure this is right, but I can't
          remember why.  xoxorich.]

Fri Feb 21 01:08:48 1992  K. Richard Pixley  (rich@cygnus.com)

        * Makefile.in, configure.in, doc: use the doc.  Build it, install
          it, clean it, etc.

Tue Feb 18 02:21:25 1992  K. Richard Pixley  (rich at cygnus.com)

        * read.c: white space and comments only.

        * configure.in: use the new atof-ns32.c for ns32k.

        * write.c: comment change only.

        * tc-m88k.[hc]: pulled in from hack's unfinished work.  These
          aren't yet integrated.

        * tc-i860.[hc]: blew off the dust.  Something must still be done
          about conflicting relocation types.

        * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
          real thing.

        * tc-i960.c, tc-sparc.c: white space and comments only.

        * tc-a29k.h: delete duplicate macro definition.

        * new file atof-ns32k.c copied from hack's last unreleased gas.

Mon Feb 17 07:51:06 1992  K. Richard Pixley  (rich at cygnus.com)

        * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
          rather than abort.

        * nearly everything.  flush ChangeLog, package as gas-1.92.1.
          ChangeLog's prior to this are sketchy at best.  I have logs.
          They just aren't ChangeLogs.
