2488 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
2489 it's better to use the one in libiberty.
2491 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2493 * symbols.c (resolve_symbol_value, case O_symbol): Undo last

2531 * Makefile.in (comparison): When comparing as.new or gasp.new, try
2532 running the binary through sed to avoid differences due to

2551 ecoff_frob_symbol if appropriate.
2553 * write.c (fixup_segment): For i386 elf and coff (for now), don't

2657 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2659 * configure.in: Set bfd_gas for all sparc targets in one place,
2660 instead of separately for each. Correctly handle user-supplied
2661 "--enable-bfd-gas" option.
2663 * gdbinit.in: Move "break abort" to end, in case gdb complains.
2665 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:

2673 (indent_level): No longer static.
2674 (print_symbol_value_1): Don't print frag address if it matches

2678 (print_expr_1): Fix whitespace before printing X_add_number.
2680 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
2681 not symbol_new, for symbols holding expression values.

2683 * write.c (fix_new_exp): Handle O_add by creating an
2684 expression-valued symbol, and calling fix_new_exp recursively.
2685 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
2686 undefined symbol and a constant, fold the constant into the fixup,
2687 and refer to the undefined symbol directly. Then process the
2688 fixup again from scratch.
2689 (write_object_file): Before calling adjust_reloc_syms, make a pass
2690 through the symbol list trying to resolve values.
2692 * write.c (print_fixup): New routine, for debugging.
2693 (write_relocs): Call bfd_install_relocation. Deleted various

2711 * write.c (write_relocs): Add file name and line number to
2712 as_fatal calls. Handle bfd_reloc_overflow case specifically when
2713 RELOC_EXPANSION_POSSIBLE.
2715 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2717 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these

2722 default definitions matching what we were doing before.
2723 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
2724 always use the varargs form if not using stdarg. It's safe to
2725 always use vfprintf, because libiberty will provide it if the

2745 false (if defined) as well as checking for reg_section.
2746 (listing_listing): Iterate fetching lines while line number is too
2747 low, and we haven't run off the end of the input file.
2749 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
2751 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

2767 X_add_number is zero.
2768 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.

2774 md_estimate_size_before_relax, md_ri_to_chars,
2775 md_create_short_jump, md_create_long_jump.
2776 (brtab_emit): Use data_section, not SEG_DATA.
2778 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2780 * config/vms-conf.h: new file, manually derived from conf.in.

2794 * config/tc-mips.c (insns_since_cache_access): Remove.
2795 (append_insn): Remove setting of insns_since_cache_access, and

2798 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2800 * config/tc-mips.c (md_shortopts): Remove E.
2801 (md_longopts): Add EB and EL.
2802 (md_parse_option): Handle -EB and -EL as separate options, rather

2807 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
2808 involving global symbols too.

2812 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
2814 * configure.in: Test for remove, not delete. Fix cross-assembler

2830 representation (only enum bitfields can avoid being bitstrings).
2831 (bitfield_suffix, setup_basic_type): new routines.
2832 (VMS_typedef_parse): use them. Now recognize bitfields of all
2833 integral types, not just type `int'. Caveat: the representation
2834 used for bitfields still does not work for objects placed in
2835 registers, and gcc's optimizer sometimes puts small structs there.
2837 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2839 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
2840 bit from const_flag.
2841 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.

2847 (vms_check_for_special_label): new routine (tc_frob_label).
2848 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
2849 and `gcc2_compiled.' labels; they won't reach here any more.
2850 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
2851 double', use `vax_g_doubles' flag to select type of double.
2852 (VMS_write_object_file) [traceback setup]: don't pass symbols
2853 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin

2861 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
2862 gets requested. [All the HACK_DEC_C_STARTUP code appears to
2863 be obsolete; gcc does it automatically for vms target. It's
2864 also misnamed, because it is for the "VAX C" run-time library,
2865 not the newer "DEC C" one which has much different startup code.]
2866 {various}: use `S_SET_xxx(symbol,new_value)' rather than
2867 `S_GET_xxx(symbol) = new_value'.

2890 fixups, store 32bits of unwind information in the fx_addnumber
2892 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
2893 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
2894 pointer to 32 bits of unwind info.
2895 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
2896 pointer to the dummy symbol; set the addend field to fx_addnumber.

2916 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
2917 for O_big literal operands (double floats and long long ints);
2918 [VMS, md_shortopts]: add second colon after 'v';
2919 (md_parse_options) [VMS, case 'v']: check for argument, so

3118 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
3119 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
3120 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
3121 message to try to ease confusion about autoconf's

3916 * read.c (emit_expr): Use memset to zero out memory, rather than
3917 going through md_number_to_chars. This permits handling symbolic

3971 (control_regs): New pointer.
3972 (m68k_ip): Use control_regs instead of testing CPU every time.

3974 print 68060 for mfloat, too.
3975 (m68k_init_after_args): Handle "68060". Use m68040up for making
3976 m68851 choice. Set control_regs.

4345 * config/tc-mips.c (append_insn): Permit branches to be switched
4346 with the preceding instruction even if .set nobopt has been seen.
4347 .set nobopt actually controls whether to bring up an instruction

4488 elf_tc_make_sections stuff. It was there to support PA braindamage
4489 which has been fixed, and in the case of elf_tc_make_sections is
4490 redundant with elf_tc_final_processing.

4593 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

4627 works). Do not permit -G with SVR4_PIC.
4628 (s_abicalls): Warn if -G was used, and force -G 0.
4629 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for

4684 get the symbol, instead of going directly for abs_symbol.
4685 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
4686 reloc is not a section symbol and is not in the symbol table.
4687 (set_symtab): New function, broken out from write_object_file.
4688 Counts symbol table instead of relying on an earlier count.
4689 (write_object_file): Call set_symtab, but do it after potentially
4690 invoking the *_frob_file macros. Don't bother counting symbols.
4691 Call symbol_remove, instead of expanding it in place. Moved the
4692 conditionalized `object_file_size' declaration down to
4693 conditionalized block where it's used. When using the absolute
4694 symbol for a fixup without a symbol, set sy_used_in_reloc.
4695 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
4696 the correct symbol for the absolute section.
4698 * subsegs.c (section_symbol): Use symbol_new instead of
4699 symbol_make, since we may want it to go into the symbol table.
4700 Make the new symbol have internal linkage. If
4701 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
4702 symbol with the newly created GAS symbol.
4703 (obj_sec_sym_ok_for_reloc): Default to always returning 0.

4711 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
4712 (sparc_ip, label "immediate"): Reject constants for pcrel
4713 instructions only if the relocation type indicates a "call"
4714 instruction and the offset is within range of a "jmpl %g0". If
4715 it's not in range, use the absolute section symbol plus an offset.
4716 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
4718 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
4720 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
4723 * configure.in: Eliminated all targets using obj-coff but not
4724 defining BFD_ASSEMBLER; I think all such targets that are
4725 supported will be matched by real CPU-OS combinations earlier in
4727 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
4728 some comments about the dpx2 configuration, but left it disabled,
4729 since it couldn't be reached before.

4748 it instead of global insn_label.
4749 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
4750 call to mips_emit_delay and pass it to mips_align.

4774 holger@botbso.rhein-main.de.)
4775 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER

4777 mask that spans frags.
4779 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
4780 this_base, not line_base. (Patch from Andreas Arens,

6509 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
6510 standard hpux include files to pick up various function decls.
6512 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

6949 Add comments to functions. Delete unused functions, variables,
6950 #defines, etc. Delete unused members within structures. Delete
6951 ldil;ble hacks -- it is believed they were installed to work
6952 around old gas bugs. Avoid using mixed case for local
6953 functions, variables, and structures. Fix formatting problems
6954 not found by GNU-indent. Add FIXME notices for things which

8118 * Extensive changes to permit symbols to contain any expression
8119 type and to delay the computation of the expression until the
8120 value is actually needed. This permits setting symbols to values
8121 calculated based on object code size. Expressions were changed to
8122 no longer be in a section, to stop the overloading of segment and
8123 expression type that previously occurred.
8125 * as.c (big_section, pass1_section, diff_section, absent_section):
8127 (expr_section): Added (used for dummy symbols which hold

8211 (previous_section, previous_subsection): New vars.
8212 (obj_elf_section): Save current place in case DWARF code wants us
8213 to pop back to it. Handle unquoted section name as well as quoted
8214 section name. Don't crash on invalid strings.
8215 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

8324 * Removed sy_forward and replaced it with an undefined expression
8325 as the value of a symbol.

8327 sy_resolved and sy_resolving single bit fields.
8328 * symbols.c (symbol_new): Don't initialize sy_forward field.

8332 * read.c (pseudo_set): Set symbolP->sy_value to an undefined
8333 expression rather than setting symbolP->sy_forward.

9362 than ECOFF line number information.
9363 (obj_ecoff_stab): Accept non-zero values for stabs line number.

9422 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
9423 the bottom (make expands variables in dependencies when the
9424 dependencies are read, not when they are used).
9426 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
9427 a29k .bss section; the mondfe program doesn't like it.

9448 source directory, if that's not the current directory.
9450 * configure.in (per-host): Accept MIPS host with BSD version

9472 process relocs if there aren't any relocs to process. Avoids
9473 malloc/free bug on SCO too.

9476 avoid some redefinition complaints on some systems.
9477 (const, volatile): Don't need these conditionally defined if we
9478 use CONST and VOLATILE from ansidecl.h.
9479 (seg_name): Use CONST, not const.
9481 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
9483 * config/tc-mips.c: Reindented to GNU standards.
9485 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
9487 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
9488 (fixup_segment): Add a29k special case; the linker is not prepared
9489 to see a segment offset here.
9491 * app.c (do_scrub_next_char): Added new state, 10, modifying state
9492 9 to only keep a space in between identifier characters.
9494 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
9496 * Makefile.in: add dvi target; as-$(config).texinfo might live in
9497 srcdir, might be in objdir.
9499 * doc/Makefile.in: dvi depends on as.dvi

9517 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
9518 bignums, but don't emit error message.
9520 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
9522 * Makefile.in (targ-cpu.o): Depend on config.h.
9524 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
9526 * app.c (do_scrub_next_char): Added new state, 9, to avoid
9527 dropping a space immediately following an identifier.
9528 * expr.c, write.c: Rewrote assert expressions to not use multiple
9529 lines; I don't think that can be done portably.
9530 * config/tc-mips.c (macro): Use $AT if target register is zero in
9531 load instruction, which it can be for a floating point load.
9533 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

9544 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
9545 z8k-opc.h, not z8k.h.
9547 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
9550 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9552 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
9554 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
9556 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
9557 to be on a single line.

9605 prototypes for all static functions. Moved existing minimal
9606 debugging format support info #ifndef OBJ_ECOFF blocks.

9608 does not support a non sign extended high 16 bits reloc. Adjusted
9609 all callers accordingly.
9610 (tc_get_register): Renamed from get_register, and made non-static.
9612 * config/mips-big.mt, config/mips-lit.mt: New files. Define

9655 * make-gas.com: Find obstack.obj if it's not in the current
9657 * read.c (s_ignore): Don't declare is_end_of_line. It's
9658 redundant, and triggers a VMS gcc compiler bug.
9660 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
9661 current segment as an argument. (Ignored in all cases but VMS.)
9662 All callers and definitions changed.

9680 argument to s_ignore. Put "#if 0" around unused code.
9681 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
9682 Call elf_xstabs for .stabs and .xstabs operators.
9684 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
9686 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
9689 * configure.in: mips-bsd configuration was missing format spec.
9692 * Makefile.in (Makefile): Depends on configure.in.
9694 * config/tc-mips.c (append_insn): Don't check for alignment of
9695 frag in memory; alignment of instructions in section is a separate
9698 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI

9715 * config/tc-sparc.c (s_xword): Now call big_cons, so large
9716 constants are accepted, but symbolic values are not. GCC will not
9717 generate the latter currently.
9719 * frags.c (frag_init): New function.
9720 (zero_address_frag, bss_address_frag): Now initialized at run
9722 * as.c (main): Call frag_init.

9765 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
9766 (fixup_segment): Make sure common-section symbols get treated the
9767 same as undefined symbols.
9768 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type
9769 bfd_reloc_code_real_type. Use seg_fix_{root,tail}P derived from

9776 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and
9779 * symbols.c (symbol_new): Argument NAME is now pointer to const.
9780 Simplified STRIP_UNDERSCORE code. Remove assumptions about null
9781 pointers in freshly allocated storage. [BFD_ASSEMBLER]: Get new

9798 new section/subsection.
9800 * read.c: Don't include ctype.h.
9801 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
9802 for now; should be machine-dependent.
9804 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
9805 targets, forcing BFD use.

9809 * config/tc-sparc.c: Use PARAMS macro for static function
9810 declarations. Use BFD_RELOC_ macros everywhere, with
9811 compatibility macros declared for non-BFD mode.
9812 (struct sparc_it) [BFD_ASSEMBLER]: Use bfd_reloc_code_real_type
9813 instead of enum reloc_type.

9972 * config/tc-sparc.c (architecture_requested, warn_on_bump,
9973 md_relax_table): Use default zero initialization.
9974 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

9989 * expr.c (operand): If character other than comma or newline is a
9990 logical end-of-line character, use the newline case.

9992 (operand): Set X_add_number field for floating-point numbers.
9993 (operand): Treat zero byte as end-of-operand.
9995 * configure.in (per-target): Look for with_bfd_assembler option.
9996 For now, only accept "no", until the merge is done.
9998 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
9999 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
10000 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
10001 * read.c: Finish conversion to S_* macros in the VMS only
10002 parts of the program. Add "const" modifier to hex_value.
10003 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
10005 * expr.c: Add "const" modifier to hex_value.
10006 * symbols.c: Finish conversion to S_* macros in the VMS only
10007 parts of the program. Add "const" modifier to
10008 md_[long,short]_jump_size. Remove declaration of const_flag
10009 (which will be declared in obj-vms.h).
10010 * write.c: Add "const" modifier to md_[long,short]_jump_size.
10011 Fix arguments to VMS_write_object_file.
10012 * config-gas.com: New file. Script for VMS systems to set up the
10013 configuration to build gas for VMS, and create config.status.
10014 * make-gas.com: Redone to work with new scheme.
10015 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
10017 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
10018 will swap bytes if needed on a big endian system. Use throughout
10020 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
10021 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
10022 types of malformed stabs. Change parsing algorithm so that we are
10023 more certain of having all of the information that we need on hand.
10024 * obj-vms.c (final_forward_reference): New function, used to help
10025 resolve the data types of as many struct elements as possible
10026 when some part of the struct is not fully defined by the compiler.
10027 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
10029 * obj-vms.c (VMS_write_object_file): Define all vtable psects
10030 as symbols as well in the object file. Look for external functions

10033 * tc-vax.c: Add '1' option for backward compatibility with older GCC
10035 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

10040 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
10042 * read.c (s_data): Always use "data_section", since it'll map to
10043 SEG_DATA or SEG_E1 if needed.
10044 (s_lcomm): Likewise with bss_section.
10045 (s_fill): Use memset, not bzero.
10047 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10049 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

10066 otherwise, use seg_name array.
10067 (seg_name): Declare only if not BFD_ASSEMBLER.
10068 (section_alignment): Declare only if not BFD_ASSEMBLER.
10069 (big_section, reg_section, pass1_section, diff_section,
10070 absent_section, text_section, data_section, bss_section): If
10071 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
10072 mapping to segT enum values.
10073 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
10074 if these are used or defined, if BFD_ASSEMBLER.
10075 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
10076 subseg_new split into two functions.
10077 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
10079 * as.h (volatile): Don't define if already defined.

10083 declare with format attribute for -Wformat checking.
10085 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
10087 * app.c, config/tc-*.c: Don't include read.h, since it is already

10091 <mtranle@paris.intellicorp.com>.
10092 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
10093 obj_format coffbfd and gas_target i386coff for target.
10094 (i[34]86-*-isc*): New host (uses sysv).
10095 * config/i386aix.mt: Removed (no longer used).
10096 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
10097 (MINUS_G): Removed.
10098 (LDFLAGS): Added, defined as -shlib.
10099 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
10100 * config/te-sco386.h (LOCAL_LABEL): Don't define.
10101 (DOT_LABEL_PREFIX): Define.
10102 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
10103 name rather than L0\001.
10104 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
10106 * symbols.c, symbols.h (local_bss_counter): Removed.
10107 * write.c (write_object_file): bss no longer uses
10108 local_bss_counter. Pass correct data and bss size to
10109 VMS_write_object_file.
10110 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
10111 argument, rather than using local_bss_counter.

10115 (size_section): Restored sanity check.
10116 (do_relocs_for): Base section address on s_paddr rather than
10117 computing it. Adjust a29k R_IHIHALF special case to account for
10118 section paddr (used to require paddr to be zero). If there are no
10119 reclos, set s_relptr to 0. Set relocation size in object_headers.
10120 (fill_section): Always set s_vaddr here, removing
10121 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
10122 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
10123 Set STYP_INFO for .comment.
10124 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
10125 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
10126 (crawl_symbols): Handle 8 character section name correctly. Use
10127 H_{SET,GET}_* macros.
10128 (do_linenos_for): Set lineno size in object_headers.
10129 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
10130 set s_vaddr here. If string_byte_count remains 4, set it back to
10131 0, and only write strings out if there are some. Call
10132 fill_section before do_relocs_for and do_linenos_for.
10133 (obj_coff_section): Handle optional quoted second argument giving
10134 section characteristics.
10135 (obj_coff_bss): Added to handle .bss.
10136 (obj_coff_ident): Added to handle .ident (puts string in .comment

10156 (do_scrub_next_char): For \", return " not '.
10157 (symbol_chars): Now const.
10159 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
10160 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
10162 * config/obj-coff.h: Don't use #elif.
10164 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
10165 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
10167 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
10169 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

10187 * Changes to support SCO 3.2v4:
10188 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
10189 SEG_BSS, fill with NOP_OPCODE.
10190 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
10191 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
10192 using ZERO_BASED_SEGMENTS.
10193 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
10194 never set segment address for SEG_E2 (.bss) and don't write out
10195 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
10196 (obj_coff_endef): Don't merge labels or symbols awaiting forward
10197 definitions, and don't merge tags with non-tags. Check for .bf
10198 rather than just checking whether the second character is b and
10199 the third character is f.
10200 (obj_coff_val): gcc can generate values which we don't handle
10201 correctly; discard information for now, since it only affects the
10202 debugging information.
10203 (tag_find_or_name): Don't insert tags in the symbol table.
10204 (yank_symbols): Don't merge labels.
10205 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

10208 (obj_coff_section): Accept and ignore a trailing quoted string, as
10209 used in AT&T i386 syntax.

10211 relative addends by the segment vaddr.
10212 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
10213 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

10355 z8000 documentation
10356 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
10359 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
10361 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
10363 * subsegs.h: add extern to segment_info declaration.
10365 * read.h: added extern declarations for comment_chars,
10366 line_comment_chars, and line_separator_chars.
10367 read.c, app.c: removed definitions of comment_chars,
10368 line_comment_chars, and line_separator_chars.

10387 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
10388 constant will not fit in an immediate field.

10393 * obj-coff.c (callj_table): Delete global variable.
10394 (obj_emit_relocations): Define it locally here, and only if
10395 TC_I960 is defined.
10397 * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.

10427 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
10428 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
10429 be used to set them all to zero as was done before.
10430 (fill_section): segment addresses now set in write_object_file.
10431 (fill_section): Don't set STYP_NOLOAD for .bss section.
10432 (fixup_segment): 386 uses strange common symbol format.

10469 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
10470 #elif, since it is not supported by old compilers.
10471 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
10472 couple of expressions in tc-m68k.c.
10474 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10476 * read.c (cons): If NO_RELOC is defined, use it.

10482 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
10483 local labels to start with a .) and set REGISTER_PREFIX to %.
10484 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
10486 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
10488 * messages.c: Comment changes.
10490 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

10493 * messages.c: If __STDC__ is not defined, define NO_STDARG.
10495 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
10497 * listing.c (debugging_pseudo): Add stabs and stabn as things to
10500 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
10502 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
10503 sections starting from zero, rather than making them consecutive.
10504 This makes subsequent reloc calculations easier, esp if the object
10505 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
10506 allocate lcomm in .data rather than in .bss. It seems that some
10507 tools can't cope with a non-zero sized bss before linkage.
10509 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10511 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10512 throughout. That enum no longer means what we thought it meant.
10514 * tc-m68k.c (md_assemble, md_parse_option): Handle new
10515 "-mno-688[58]1" options.
10517 * tc-m68k.c: Added CPU32 support.
10519 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

10530 * Makefile.in (install): if $(tooldir) exists, install as in
10533 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10535 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10536 .word is < -32768 or > 32767. The -J flag causes the error to be
10537 ignored. This is to catch over-sized switches generated by gcc on
10538 systems which don't support the broken .word hack.
10539 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10540 write.c (fixup_segment): check for signed .word overflow if
10541 WARN_SIGNED_OVERFLOW_WORD.
10543 * write.c (fixup_segment): fixed missing parens in expression
10544 checking for byte or word overflow.
10546 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
10547 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
10548 WARN_SIGNED_OVERFLOW_WORD.

10558 * tc-i386.h : new coff defines
10560 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
10562 * input-scrub.c (input_scrub_push): call input_file_begin, not
10564 messages.c (as_perror): print ": " between the passed in error and
10565 the strerror, like perror does.

10574 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
10575 Motorola and MIT syntax; gas can now assemble either type of
10577 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
10578 From Steve Chamberlain:
10579 m68kcoff.mt: for m68k COFF.
10580 obj-coffbfd.c: (fixup_mdeps) added
10581 (size_section) removed bad sanity check
10582 (fill_section) added rs_machine_dependent case
10583 (write_object_file) call fixup_mdeps
10584 (fixup_segment) set fx_subsy to 0.
10585 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
10587 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
10590 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

10614 tc-i960.c (md_ri_to_chars): Always output bout object file in
10615 little endian byte order (used to use endianness of host).
10617 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10619 * config/tc-m68k.c (init_table): Now const. Always include 68851
10620 data, so that "bc" is available to 68040 cache instructions.
10621 Added "tt0", "tt1", and 68ec030 variants.
10622 (md_assemble): Complain if 68000 (only) and 68881 are specified.
10623 (enum _register): Added TT0, TT1.
10624 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
10625 line number correctly in "internal error" messages. Don't print
10626 architecture-mismatch message for operand errors.
10628 From Colin Smith (colin@wrs.com):
10629 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
10630 than install_operand.

10639 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
10641 * Makefile.in: defined TARGET_CPU for C code so that it can choose
10642 one element of a family.
10644 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
10646 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
10647 so that we can assemble hand-written libgcc code.
10649 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10651 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
10652 has already been formatted (but may still contain %-characters).
10653 (as_bad): Likewise.
10655 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
10657 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
10658 written with indirection on the last two operands, which can be
10659 either data or address registers. Added a new operand type 'r'
10660 which accepts either register type. Added '(' to notend stuff in
10661 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
10663 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
10665 * as.h (enum _relax_state): Start off at one, not zero, to better
10666 catch uninitialized-variable errors.
10667 (linkrelax): Declare new variable.
10669 * messages.c (warning_count, error_count): Default initializer is
10672 * write.c: Merged some declarations, using PARMS macro.

10674 data_last_frag): No longer static.
10675 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
10676 defined, call it. Change segments before calling fixup_segment.
10677 (relax_align): If linkrelax, provide extra padding.
10679 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
10680 their not having symbols associated.
10682 * tc-i960.c (norelax, instrument_branches): Default initializer is
10684 (linkrelax): Delete variable definition.

10707 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
10708 being used with args swapped, causing occasional lossage when
10709 refilling buffers after an include file.
10711 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
10713 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
10714 version. Discard bogus DONTDEF version.
10715 (as_warn, as_bad, as_fatal): Likewise.

10719 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
10720 selected architecture, print a message saying so and listing what
10721 processors support it, rather than saying "operands mismatch".

10772 (md_assemble): If no CPU has been set (even if FPU/PMMU
10773 characteristics have been), default to 68020. Don't need extra
10774 quotes around error string.

10910 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
10912 * Makefile.in (install): Install into $(tooldir)/bin, since that's
10913 where gcc looks for it.
10915 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
10917 * Makefile.in: Changed some lines to be less confusing for some

10957 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
10959 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

10983 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
10985 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
10987 * expr.c (operand): if can't work out what sort of operand it is,
10988 then look through FLT_CHARS for a hint.
10990 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
10992 * Makefile.in, configure.in: removed traces of namesubdir,
10993 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10994 copyrights to '92, changed some from Cygnus to FSF.
10996 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
10997 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10998 copyrights to '92, changed some from Cygnus to FSF.
11000 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11002 * expr.c: If an expression is single comma, then return with
11003 SEG_ABSENT rather than an error - since the sparc front end does
11004 really strange things with things like fbge,a
11006 * as.h: include bfd.h if using many sections
11007 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
11008 local labels didn't work.
11009 * listing.c (list_symbol_table): don't core dump when there's no
11011 * write.c, write.h: call fix_new with the right number of args on
11013 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
11016 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11018 * app.c: MRI compatibility - allow single quote to start a string.
11019 * as.c: fix typo recently introduced.
11020 * as.h : Don't include aout/reloc.h - it's not right for COFF!
11021 * expr.c: Much rewriting, to accomodate MRI syntax for
11022 expressions. Also easier to read now.
11023 * listing.c: Put back defuns
11024 * read.c: modified to accept MRI syntax, put back listing pseudo
11025 ops so that an assembler built with NO_LISTING ignores list ops
11027 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
11028 machine is a SPARC or a 29K.
11029 * config/obj-aout.c: added s_sect pseudo op
11030 * config/obj-coffbfd.c: lints, set the filehdr flags right and
11031 fill in the timestamp.
11032 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
11033 anymore, define all the relocs which the tc-<x> bit will use so we
11034 can translate from them to the coff types.
11035 * config/tc-a29k.c: reloc_type isn't ane enum any more
11036 * config/tc-m68k.c: Added NO_RELOC definition.
11038 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
11040 * Makefile.in: put header files before C source for TAGS; remove
11041 references to non-existent syscalls.h.
11043 * read.c, write.c subsegs.c: back out the .bss changes.
11045 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
11047 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
11049 * a.out.h: removed.
11051 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
11053 * symbols.c (local_label_name): symbols now start with ^A.
11055 * read.c, subsegs.c, write.c obj-coff.c: added handling of
11056 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
11057 generate these sections. .align: will use NOP_OPCODE or 0
11058 for padding. This is just for being nice to the
11061 * expr.c (operand): changed to generate local label "\001L0"
11062 starting with a ^A so that it is recognized as a local label.
11064 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
11066 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
11067 i/o opcodes - inb, inw, outb and outw. string manipulation with
11068 att syntax - scmp, slod, smov, ssca, ssto.
11070 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
11071 to just after .file .
11073 In obj_crawl_symbol_chain() where it tries to put the external
11074 symbols apart, with the condition:
11075 (!S_IS_DEFINED(symbolP) &&
11076 !S_IS_DEBUG(symbolP) &&
11077 !SF_GET_STATICS(symbolP))
11078 it was moving too many symbols out. So I switch it back to the
11080 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
11082 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
11083 so that we don't use the F_RELFLG which make the linker complain
11084 that somebody has stripped the relocation info.
11086 Also, the AIX ld program require that the relocation table
11087 is sorted by r_vaddr like the standard ATT assembler does.
11089 [he also changed the sizeof(struct ...)'s into the coff
11090 style FOOSZ macros. I'm not sure this is right, but I can't
11091 remember why. xoxorich.]
11093 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
11095 * Makefile.in, configure.in, doc: use the doc. Build it, install
11098 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
11100 * read.c: white space and comments only.
11102 * configure.in: use the new atof-ns32.c for ns32k.
11104 * write.c: comment change only.
11106 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
11107 aren't yet integrated.
11109 * tc-i860.[hc]: blew off the dust. Something must still be done
11110 about conflicting relocation types.
11112 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
11115 * tc-i960.c, tc-sparc.c: white space and comments only.
11117 * tc-a29k.h: delete duplicate macro definition.
11119 * new file atof-ns32k.c copied from hack's last unreleased gas.
11121 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
11123 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
11126 * nearly everything. flush ChangeLog, package as gas-1.92.1.
11127 ChangeLog's prior to this are sketchy at best. I have logs.
11128 They just aren't ChangeLogs.
