485 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
486 -non_shared to use NO_PIC (this is how the Irix 5 assembler
487 works). Do not permit -G with SVR4_PIC.
488 (s_abicalls): Warn if -G was used, and force -G 0.
489 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
490 anything but a.out, not just for ELF. For ECOFF, don't generate a
491 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
493 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
495 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

501 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
503 * Makefile.in (config-stamp): If `defs' is defined, emit a
504 preprocessor directive to create a macro named by this value into
505 config.new; don't explicitly go for BFD_ASSEMBLER.
506 * configure.in: Define `defs', not `BFDDEF'. Set it to
507 MANY_SEGMENTS for any obj-coffbfd target.
508 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
509 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
511 (LOCAL_LOADLIBES): Deleted.
512 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
513 * config/m88kcoff.mt (TDEFINES): Ditto.
514 * config/ebmon29k.mt: Deleted.
515 * config/h8300hds.mt: Deleted.
516 * config/ic960coff.mt: Deleted.
517 * config/sparc.mt: Deleted.

539 bfd_set_symtab is called.
540 (dump_section_relocs): Note whether a symbol is a section symbol
542 (adjust_reloc_syms): For now, always supply an absolute symbol for
543 fixups without symbols but not yet `done'. Use section_symbol to
544 get the symbol, instead of going directly for abs_symbol.
545 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
546 reloc is not a section symbol and is not in the symbol table.
547 (set_symtab): New function, broken out from write_object_file.
548 Counts symbol table instead of relying on an earlier count.
549 (write_object_file): Call set_symtab, but do it after potentially
550 invoking the *_frob_file macros. Don't bother counting symbols.
551 Call symbol_remove, instead of expanding it in place. Moved the
552 conditionalized `object_file_size' declaration down to
553 conditionalized block where it's used. When using the absolute
554 symbol for a fixup without a symbol, set sy_used_in_reloc.
555 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
556 the correct symbol for the absolute section.
558 * subsegs.c (section_symbol): Use symbol_new instead of
559 symbol_make, since we may want it to go into the symbol table.
560 Make the new symbol have internal linkage. If
561 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
562 symbol with the newly created GAS symbol.
563 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
564 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
566 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.

569 (in_signed_range): New function.
571 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
572 (sparc_ip, label "immediate"): Reject constants for pcrel
573 instructions only if the relocation type indicates a "call"
574 instruction and the offset is within range of a "jmpl %g0". If
575 it's not in range, use the absolute section symbol plus an offset.
576 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
578 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
580 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
583 * configure.in: Eliminated all targets using obj-coff but not
584 defining BFD_ASSEMBLER; I think all such targets that are
585 supported will be matched by real CPU-OS combinations earlier in
587 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
588 some comments about the dpx2 configuration, but left it disabled,
589 since it couldn't be reached before.
590 (target a29k-amd-ebmonold): Deleted.
592 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

600 the 'j' operand if there are no further alternatives for this
603 * config/obj-coffbfd.c (adjust_stab_section): Initialize
604 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
605 is not SEG_UNKNOWN rather than checking whether it is >= 0.
607 * config/tc-mips.c (mips_align): Take new argument, label, and use
608 it instead of global insn_label.
609 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
610 call to mips_emit_delay and pass it to mips_align.
612 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
614 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
616 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
617 argument to a .callinfo directive. Don't loop forever on errors.
619 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
620 use pre-defined registers as arguments.
622 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
624 * write.c (write_object_file): Check both S_IS_LOCAL and
625 S_IS_EXTERNAL when deciding whether to discard a symbol.
627 * config-gas.com: Scan Makefile.in, not version.c, for current
628 version number. Delete all versions of temp files when finished
629 with them. Create config.h.
631 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
632 values to reduce number of lookups with S_GET_VALUE. Skip debug
633 symbols to avoid "a really nasty bug". (From Holger Teutsch,
634 holger@botbso.rhein-main.de.)
635 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
636 field. (Also from Holger Teutsch.) Watch for a would-be register
637 mask that spans frags.
639 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
640 this_base, not line_base. (Patch from Andreas Arens,
641 ari@obelix.av.rwth-aachen.de.)
643 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
644 look local if they're exported or undefined. Used to be done for
647 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

651 (lex_type): Use it for `%'.
653 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
654 (vip_op): Now static, and returns void. Callers changed. Added

2382 descriptor information to the BFD symbol.
2383 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

2434 pass new argument for i, j and o cases.
2435 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
2436 special handling when generating SVR4 PIC code.
2437 (mips_ip, tc_get_register, s_frame): Use macros FP, SP, GP and AT
2438 rather than hard coded constants.
2439 (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and

2656 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2657 the table, require that the one without bit 0x1000000 set come

2768 * configure.in: Set bfd_gas for all sparc targets. Added facility
2769 for keeping or rejecting configurations still under development;
2770 default is to assume production environment, and reject configs
2771 still being worked on. Mark Elf configurations (except sparc and
2772 i386) as developmental. Deleted cases matching some generic names
2773 in favor of more specific names. (E.g., when we get Alpha
2774 support, we'll still only support VMS for Vax.)

2777 * config/tc-sparc.c (md_end): Function deleted.
2778 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

2788 against placing additional object-file dependent code here. Warn
2789 against contaminating all of GAS with the internals of tc-hppa.c
2790 through inclusion of tc-hppa.h. Delete all forward declarations
2791 for functions only used within tc-hppa.c, likewise for structures,
2792 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2793 conditional code in a few small places.
2795 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2796 structures, global variables, forward declarations together.

2798 conditional code -- try to group conditional code together
2799 into a few places. Make all functions and variables which
2800 are only used within tc-hppa.c static. PARAMize all functions.
2801 Add comments to functions. Delete unused functions, variables,
2802 #defines, etc. Delete unused members within structures. Delete
2803 ldil;ble hacks -- it is believed they were installed to work
2804 around old gas bugs. Avoid using mixed case for local
2805 functions, variables, and structures. Fix formatting problems
2806 not found by GNU-indent. Add FIXME notices for things which
2807 should be worked on the near future. Delete lots of old
2808 useless (1.36 PA-SOM) code.
2810 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
2811 field of the fixS structure. Needed to build unwind

2820 which do not involve function symbols.
2822 * config/tc-hppa.h: Reindent with GNU-indent. Delete references

2837 a multiple of the section alignment rather than always a
2840 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

3951 * Extensive changes to permit symbols to contain any expression
3952 type and to delay the computation of the expression until the
3953 value is actually needed. This permits setting symbols to values
3954 calculated based on object code size. Expressions were changed to
3955 no longer be in a section, to stop the overloading of segment and
3956 expression type that previously occurred.
3958 * as.c (big_section, pass1_section, diff_section, absent_section):
3960 (expr_section): Added (used for dummy symbols which hold

4044 (previous_section, previous_subsection): New vars.
4045 (obj_elf_section): Save current place in case DWARF code wants us
4046 to pop back to it. Handle unquoted section name as well as quoted
4047 section name. Don't crash on invalid strings.
4048 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

4157 * Removed sy_forward and replaced it with an undefined expression
4158 as the value of a symbol.
4159 * struc-symbol.h (struct symbol): Removed sy_forward field. Added
4160 sy_resolved and sy_resolving single bit fields.
4161 * symbols.c (symbol_new): Don't initialize sy_forward field.
4162 (resolve_symbol_value): New function to adjust symbol value by
4163 fragment address, using recursion to resolve forward symbols.

4165 * read.c (pseudo_set): Set symbolP->sy_value to an undefined
4166 expression rather than setting symbolP->sy_forward.
4167 * write.c (write_object_file): Use resolve_symbol_value on
4168 symbols, keeping the common case (the old behaviour) inline.

5164 than ECOFF line number information.
5165 (obj_ecoff_stab): Accept non-zero values for stabs line number.

5226 dependencies are read, not when they are used).
5228 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
5229 a29k .bss section; the mondfe program doesn't like it.

5274 process relocs if there aren't any relocs to process. Avoids
5275 malloc/free bug on SCO too.
5277 * as.h: Move local include files below system include files, to
5278 avoid some redefinition complaints on some systems.
5279 (const, volatile): Don't need these conditionally defined if we
5280 use CONST and VOLATILE from ansidecl.h.
5281 (seg_name): Use CONST, not const.
5283 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5285 * config/tc-mips.c: Reindented to GNU standards.

5289 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5290 (fixup_segment): Add a29k special case; the linker is not prepared
5291 to see a segment offset here.
5293 * app.c (do_scrub_next_char): Added new state, 10, modifying state

5296 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5298 * Makefile.in: add dvi target; as-$(config).texinfo might live in

5314 bignums, but don't emit error message.
5316 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
5318 * Makefile.in (targ-cpu.o): Depend on config.h.
5320 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5322 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5323 dropping a space immediately following an identifier.
5324 * expr.c, write.c: Rewrote assert expressions to not use multiple
5325 lines; I don't think that can be done portably.
5326 * config/tc-mips.c (macro): Use $AT if target register is zero in
5327 load instruction, which it can be for a floating point load.
5329 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5350 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5352 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5353 to be on a single line.

5401 prototypes for all static functions. Moved existing minimal
5402 debugging format support info #ifndef OBJ_ECOFF blocks.
5403 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
5404 does not support a non sign extended high 16 bits reloc. Adjusted
5405 all callers accordingly.
5406 (tc_get_register): Renamed from get_register, and made non-static.
5408 * config/mips-big.mt, config/mips-lit.mt: New files. Define

5451 * make-gas.com: Find obstack.obj if it's not in the current
5453 * read.c (s_ignore): Don't declare is_end_of_line. It's
5454 redundant, and triggers a VMS gcc compiler bug.
5456 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5457 current segment as an argument. (Ignored in all cases but VMS.)
5458 All callers and definitions changed.

5755 md_relax_table): Use default zero initialization.
5756 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5757 latter, instead of selecting with preprocessor conditionals.
5759 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5761 * configure.in: recognise all sparclite variants

5769 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5771 * expr.c (operand): If character other than comma or newline is a
5772 logical end-of-line character, use the newline case.
5773 From Eric Youngdale:
5774 (operand): Set X_add_number field for floating-point numbers.
5775 (operand): Treat zero byte as end-of-operand.
5777 * configure.in (per-target): Look for with_bfd_assembler option.
5778 For now, only accept "no", until the merge is done.
5780 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5781 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5782 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5783 * read.c: Finish conversion to S_* macros in the VMS only
5784 parts of the program. Add "const" modifier to hex_value.
5785 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5787 * expr.c: Add "const" modifier to hex_value.
5788 * symbols.c: Finish conversion to S_* macros in the VMS only
5789 parts of the program. Add "const" modifier to
5790 md_[long,short]_jump_size. Remove declaration of const_flag
5791 (which will be declared in obj-vms.h).
5792 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5793 Fix arguments to VMS_write_object_file.
5794 * config-gas.com: New file. Script for VMS systems to set up the
5795 configuration to build gas for VMS, and create config.status.
5796 * make-gas.com: Redone to work with new scheme.
5797 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5799 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5800 will swap bytes if needed on a big endian system. Use throughout
5802 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5803 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5804 types of malformed stabs. Change parsing algorithm so that we are
5805 more certain of having all of the information that we need on hand.
5806 * obj-vms.c (final_forward_reference): New function, used to help
5807 resolve the data types of as many struct elements as possible
5808 when some part of the struct is not fully defined by the compiler.

5811 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5812 as symbols as well in the object file. Look for external functions
5813 that start with "__vt.", and turn them into variables, since the
5814 g++ compiler is incapable of doing this.
5815 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5817 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5818 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5819 have the name of the source file yet.
5820 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5822 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5824 * read.c (s_data): Always use "data_section", since it'll map to
5825 SEG_DATA or SEG_E1 if needed.
5826 (s_lcomm): Likewise with bss_section.
5827 (s_fill): Use memset, not bzero.
5829 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5850 (section_alignment): Declare only if not BFD_ASSEMBLER.
5851 (big_section, reg_section, pass1_section, diff_section,
5852 absent_section, text_section, data_section, bss_section): If
5853 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5854 mapping to segT enum values.
5855 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5856 if these are used or defined, if BFD_ASSEMBLER.
5857 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5858 subseg_new split into two functions.
5859 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5861 * as.h (volatile): Don't define if already defined.
5862 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5864 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5865 declare with format attribute for -Wformat checking.
5867 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5869 * app.c, config/tc-*.c: Don't include read.h, since it is already
5872 * These are based on patches from Minh Tran-le
5873 <mtranle@paris.intellicorp.com>.
5874 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5875 obj_format coffbfd and gas_target i386coff for target.
5876 (i[34]86-*-isc*): New host (uses sysv).
5877 * config/i386aix.mt: Removed (no longer used).
5878 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5880 (LDFLAGS): Added, defined as -shlib.
5881 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5882 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5883 (DOT_LABEL_PREFIX): Define.
5884 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5885 name rather than L0\001.
5886 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5888 * symbols.c, symbols.h (local_bss_counter): Removed.
5889 * write.c (write_object_file): bss no longer uses
5890 local_bss_counter. Pass correct data and bss size to
5891 VMS_write_object_file.

5897 (size_section): Restored sanity check.
5898 (do_relocs_for): Base section address on s_paddr rather than
5899 computing it. Adjust a29k R_IHIHALF special case to account for
5900 section paddr (used to require paddr to be zero). If there are no
5901 reclos, set s_relptr to 0. Set relocation size in object_headers.
5902 (fill_section): Always set s_vaddr here, removing
5903 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5904 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5905 Set STYP_INFO for .comment.
5906 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5907 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5909 H_{SET,GET}_* macros.
5910 (do_linenos_for): Set lineno size in object_headers.
5911 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5912 set s_vaddr here. If string_byte_count remains 4, set it back to
5913 0, and only write strings out if there are some. Call
5914 fill_section before do_relocs_for and do_linenos_for.
5915 (obj_coff_section): Handle optional quoted second argument giving
5916 section characteristics.
5917 (obj_coff_bss): Added to handle .bss.
5918 (obj_coff_ident): Added to handle .ident (puts string in .comment

5938 (do_scrub_next_char): For \", return " not '.
5939 (symbol_chars): Now const.
5941 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5942 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5944 * config/obj-coff.h: Don't use #elif.
5946 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5947 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5949 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5951 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5973 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5974 using ZERO_BASED_SEGMENTS.
5975 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5976 never set segment address for SEG_E2 (.bss) and don't write out
5977 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5978 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5979 definitions, and don't merge tags with non-tags. Check for .bf
5980 rather than just checking whether the second character is b and
5981 the third character is f.
5982 (obj_coff_val): gcc can generate values which we don't handle
5983 correctly; discard information for now, since it only affects the
5984 debugging information.
5985 (tag_find_or_name): Don't insert tags in the symbol table.
5986 (yank_symbols): Don't merge labels.
5987 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6042 options. Updated options documentation for m68k. Some minor
6043 wording/punctuation changes.

6126 GNU `indent'. Some cleanup still needed, especially of comments.
6128 * configure.in: No te-386bsd.h file exists; don't try to use it.
6130 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
6132 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
6133 could be doing emulation.
6135 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6138 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6165 consistently const, and always initialized them. Included read.h.
6167 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6169 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6170 constant will not fit in an immediate field.
6171 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
6173 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
6175 * obj-coff.c (callj_table): Delete global variable.

6190 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
6191 so widening works consistently.
6193 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
6195 * version.c: Put conditional "const" before version_string, not

6203 * obj-coffbfd.c (write_object_file): check return value of
6206 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6208 * Support for i386-sysv.
6209 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
6210 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
6211 be used to set them all to zero as was done before.

6213 (fill_section): Don't set STYP_NOLOAD for .bss section.
6214 (fixup_segment): 386 uses strange common symbol format.

6233 * tc-m68k.c (get_num): make it work for all segments, not just the
6236 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
6238 * configure.in: recognize i386-*-bsd emulation.

6247 * tc-z8k.c: lots of bug fixes
6249 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6251 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6252 #elif, since it is not supported by old compilers.
6253 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6254 couple of expressions in tc-m68k.c.
6256 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6258 * read.c (cons): If NO_RELOC is defined, use it.
6260 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6262 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6264 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6265 local labels to start with a .) and set REGISTER_PREFIX to %.
6266 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6268 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

6282 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6284 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6285 sections starting from zero, rather than making them consecutive.
6286 This makes subsequent reloc calculations easier, esp if the object
6287 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6288 allocate lcomm in .data rather than in .bss. It seems that some
6289 tools can't cope with a non-zero sized bss before linkage.
6291 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6293 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6294 throughout. That enum no longer means what we thought it meant.

6297 "-mno-688[58]1" options.
6299 * tc-m68k.c: Added CPU32 support.

6310 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6312 * Makefile.in (install): if $(tooldir) exists, install as in
6315 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6317 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6318 .word is < -32768 or > 32767. The -J flag causes the error to be
6319 ignored. This is to catch over-sized switches generated by gcc on
6320 systems which don't support the broken .word hack.
6321 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6322 write.c (fixup_segment): check for signed .word overflow if
6323 WARN_SIGNED_OVERFLOW_WORD.
6325 * write.c (fixup_segment): fixed missing parens in expression
6326 checking for byte or word overflow.
6328 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
6329 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
6330 WARN_SIGNED_OVERFLOW_WORD.

6340 * tc-i386.h : new coff defines
6342 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6344 * input-scrub.c (input_scrub_push): call input_file_begin, not
6346 messages.c (as_perror): print ": " between the passed in error and
6347 the strerror, like perror does.
6349 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6351 * Makefile.in: use gas_target instead of modifying target_cpu.
6352 From Steve Chamberlain:
6353 Makefile.in: Handle m68*-*-coff*.
6354 read.c, read.h: add mult argument to s_space
6356 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6357 Motorola and MIT syntax; gas can now assemble either type of
6359 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
6360 From Steve Chamberlain:
6361 m68kcoff.mt: for m68k COFF.
6362 obj-coffbfd.c: (fixup_mdeps) added

6365 (write_object_file) call fixup_mdeps
6366 (fixup_segment) set fx_subsy to 0.
6367 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6369 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6372 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6374 * Makefile.in (LIBS): Include opcode library.
6376 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6396 tc-i960.c (md_ri_to_chars): Always output bout object file in
6397 little endian byte order (used to use endianness of host).
6399 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6401 * config/tc-m68k.c (init_table): Now const. Always include 68851
6402 data, so that "bc" is available to 68040 cache instructions.
6403 Added "tt0", "tt1", and 68ec030 variants.
6404 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6405 (enum _register): Added TT0, TT1.
6406 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6407 line number correctly in "internal error" messages. Don't print
6408 architecture-mismatch message for operand errors.
6410 From Colin Smith (colin@wrs.com):
6411 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6412 than install_operand.

6416 * listing.c (buffer_line): rewind to the start of include
6417 files, they might be included twice.

6424 one element of a family.
6426 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
6428 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6429 so that we can assemble hand-written libgcc code.
6431 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6433 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6434 has already been formatted (but may still contain %-characters).
6437 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6439 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6440 written with indirection on the last two operands, which can be
6441 either data or address registers. Added a new operand type 'r'
6442 which accepts either register type. Added '(' to notend stuff in
6443 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6445 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

6461 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6462 their not having symbols associated.
6464 * tc-i960.c (norelax, instrument_branches): Default initializer is
6466 (linkrelax): Delete variable definition.

6489 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
6490 being used with args swapped, causing occasional lossage when
6491 refilling buffers after an include file.
6493 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
6495 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6496 version. Discard bogus DONTDEF version.
6497 (as_warn, as_bad, as_fatal): Likewise.

6501 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6502 selected architecture, print a message saying so and listing what

6524 * read.c (s_fill): make the .fill size clamped error a warn and
6525 fix bug where 0's were always placed.
6527 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
6528 two bytes of any constant with 0xff:

6547 * configure.in (mips host): Accept "ultrix" with version number.
6549 * expr.c (floating_constant): Separate "=-" to avoid confusing
6550 ancient or broken compilers.
6552 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
6553 processor/opcode mismatch, so reword the error message.
6554 (md_assemble): If no CPU has been set (even if FPU/PMMU
6555 characteristics have been), default to 68020. Don't need extra
6556 quotes around error string.
6558 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6560 * read.c (potable): Revert sac's incorrect change made Jul 13.

6638 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6640 * write.c (write_object_file): keep the fix_tail clean, which
6641 fixes a bug in -R where relocations were being lost.

6690 start addresses to match required alignment.
6692 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6694 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6695 where gcc looks for it.
6697 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6699 * Makefile.in: Changed some lines to be less confusing for some

6765 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6767 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6769 * expr.c (operand): if can't work out what sort of operand it is,
6770 then look through FLT_CHARS for a hint.
6772 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6774 * Makefile.in, configure.in: removed traces of namesubdir,

6778 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6779 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6780 copyrights to '92, changed some from Cygnus to FSF.
6782 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6784 * expr.c: If an expression is single comma, then return with
6785 SEG_ABSENT rather than an error - since the sparc front end does
6786 really strange things with things like fbge,a
6788 * as.h: include bfd.h if using many sections
6789 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6790 local labels didn't work.
6791 * listing.c (list_symbol_table): don't core dump when there's no
6793 * write.c, write.h: call fix_new with the right number of args on
6795 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6798 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6800 * app.c: MRI compatibility - allow single quote to start a string.
6801 * as.c: fix typo recently introduced.
6802 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6803 * expr.c: Much rewriting, to accomodate MRI syntax for
6804 expressions. Also easier to read now.
6805 * listing.c: Put back defuns
6806 * read.c: modified to accept MRI syntax, put back listing pseudo
6807 ops so that an assembler built with NO_LISTING ignores list ops
6809 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6810 machine is a SPARC or a 29K.
6811 * config/obj-aout.c: added s_sect pseudo op
6812 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6813 fill in the timestamp.
6814 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6815 anymore, define all the relocs which the tc-<x> bit will use so we
6816 can translate from them to the coff types.
6817 * config/tc-a29k.c: reloc_type isn't ane enum any more
6818 * config/tc-m68k.c: Added NO_RELOC definition.
6820 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6822 * Makefile.in: put header files before C source for TAGS; remove
6823 references to non-existent syscalls.h.
6825 * read.c, write.c subsegs.c: back out the .bss changes.
6827 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6829 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6833 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6835 * symbols.c (local_label_name): symbols now start with ^A.
6837 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6838 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6839 generate these sections. .align: will use NOP_OPCODE or 0
6840 for padding. This is just for being nice to the
6843 * expr.c (operand): changed to generate local label "\001L0"
6844 starting with a ^A so that it is recognized as a local label.
6846 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6848 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6849 i/o opcodes - inb, inw, outb and outw. string manipulation with
6850 att syntax - scmp, slod, smov, ssca, ssto.
6852 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6853 to just after .file .
6855 In obj_crawl_symbol_chain() where it tries to put the external
6856 symbols apart, with the condition:
6857 (!S_IS_DEFINED(symbolP) &&
6858 !S_IS_DEBUG(symbolP) &&
6859 !SF_GET_STATICS(symbolP))
6860 it was moving too many symbols out. So I switch it back to the
6862 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6864 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6865 so that we don't use the F_RELFLG which make the linker complain
6866 that somebody has stripped the relocation info.
6868 Also, the AIX ld program require that the relocation table
6869 is sorted by r_vaddr like the standard ATT assembler does.
6871 [he also changed the sizeof(struct ...)'s into the coff
6872 style FOOSZ macros. I'm not sure this is right, but I can't
6873 remember why. xoxorich.]
6875 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6877 * Makefile.in, configure.in, doc: use the doc. Build it, install

6882 * read.c: white space and comments only.
6884 * configure.in: use the new atof-ns32.c for ns32k.
6886 * write.c: comment change only.
6888 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6889 aren't yet integrated.
6891 * tc-i860.[hc]: blew off the dust. Something must still be done
6892 about conflicting relocation types.
6894 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6897 * tc-i960.c, tc-sparc.c: white space and comments only.
6899 * tc-a29k.h: delete duplicate macro definition.
6901 * new file atof-ns32k.c copied from hack's last unreleased gas.
6903 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6905 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6908 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6909 ChangeLog's prior to this are sketchy at best. I have logs.
6910 They just aren't ChangeLogs.
6914 version-control: never
