486 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
487 (load_address): Handle EMBEDDED_PIC.
488 (macro): Handle EMBEDDED_PIC in all PIC cases.
489 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
490 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
491 -non_shared to use NO_PIC (this is how the Irix 5 assembler
492 works). Do not permit -G with SVR4_PIC.
493 (s_abicalls): Warn if -G was used, and force -G 0.
494 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
495 anything but a.out, not just for ELF. For ECOFF, don't generate a
496 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
498 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
500 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

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

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

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

605 the 'j' operand if there are no further alternatives for this
608 * config/obj-coffbfd.c (adjust_stab_section): Initialize
609 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
610 is not SEG_UNKNOWN rather than checking whether it is >= 0.
612 * config/tc-mips.c (mips_align): Take new argument, label, and use
613 it instead of global insn_label.
614 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
615 call to mips_emit_delay and pass it to mips_align.
617 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
619 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
621 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
622 argument to a .callinfo directive. Don't loop forever on errors.
624 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
625 use pre-defined registers as arguments.
627 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
629 * write.c (write_object_file): Check both S_IS_LOCAL and
630 S_IS_EXTERNAL when deciding whether to discard a symbol.
632 * config-gas.com: Scan Makefile.in, not version.c, for current
633 version number. Delete all versions of temp files when finished
634 with them. Create config.h.
636 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
637 values to reduce number of lookups with S_GET_VALUE. Skip debug

639 holger@botbso.rhein-main.de.)
640 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
641 field. (Also from Holger Teutsch.) Watch for a would-be register
642 mask that spans frags.
644 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
645 this_base, not line_base. (Patch from Andreas Arens,
646 ari@obelix.av.rwth-aachen.de.)
648 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
649 look local if they're exported or undefined. Used to be done for
652 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

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

2439 pass new argument for i, j and o cases.
2440 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2443 rather than hard coded constants.
2444 (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and

2661 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2662 the table, require that the one without bit 0x1000000 set come

2774 for keeping or rejecting configurations still under development;
2775 default is to assume production environment, and reject configs
2776 still being worked on. Mark Elf configurations (except sparc and
2777 i386) as developmental. Deleted cases matching some generic names
2778 in favor of more specific names. (E.g., when we get Alpha
2779 support, we'll still only support VMS for Vax.)

2782 * config/tc-sparc.c (md_end): Function deleted.
2783 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

2793 against placing additional object-file dependent code here. Warn
2794 against contaminating all of GAS with the internals of tc-hppa.c
2795 through inclusion of tc-hppa.h. Delete all forward declarations
2796 for functions only used within tc-hppa.c, likewise for structures,
2797 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2798 conditional code in a few small places.
2800 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2801 structures, global variables, forward declarations together.

2803 conditional code -- try to group conditional code together
2804 into a few places. Make all functions and variables which
2805 are only used within tc-hppa.c static. PARAMize all functions.
2806 Add comments to functions. Delete unused functions, variables,
2807 #defines, etc. Delete unused members within structures. Delete
2808 ldil;ble hacks -- it is believed they were installed to work
2809 around old gas bugs. Avoid using mixed case for local
2810 functions, variables, and structures. Fix formatting problems
2811 not found by GNU-indent. Add FIXME notices for things which
2812 should be worked on the near future. Delete lots of old
2813 useless (1.36 PA-SOM) code.
2815 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
2816 field of the fixS structure. Needed to build unwind

3956 * Extensive changes to permit symbols to contain any expression
3957 type and to delay the computation of the expression until the
3958 value is actually needed. This permits setting symbols to values
3959 calculated based on object code size. Expressions were changed to
3960 no longer be in a section, to stop the overloading of segment and
3961 expression type that previously occurred.
3963 * as.c (big_section, pass1_section, diff_section, absent_section):
3965 (expr_section): Added (used for dummy symbols which hold

4165 sy_resolved and sy_resolving single bit fields.
4166 * symbols.c (symbol_new): Don't initialize sy_forward field.

5169 than ECOFF line number information.
5170 (obj_ecoff_stab): Accept non-zero values for stabs line number.

5202 * doc/as.texinfo: First pass at using new texinfo features --
5203 variables, conditional tests. Far from complete.

5231 dependencies are read, not when they are used).
5233 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
5234 a29k .bss section; the mondfe program doesn't like it.

5255 source directory, if that's not the current directory.
5257 * configure.in (per-host): Accept MIPS host with BSD version

5279 process relocs if there aren't any relocs to process. Avoids
5280 malloc/free bug on SCO too.
5282 * as.h: Move local include files below system include files, to
5283 avoid some redefinition complaints on some systems.
5284 (const, volatile): Don't need these conditionally defined if we
5285 use CONST and VOLATILE from ansidecl.h.
5286 (seg_name): Use CONST, not const.
5288 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5290 * config/tc-mips.c: Reindented to GNU standards.

5294 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5295 (fixup_segment): Add a29k special case; the linker is not prepared
5296 to see a segment offset here.
5298 * app.c (do_scrub_next_char): Added new state, 10, modifying state

5301 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5303 * Makefile.in: add dvi target; as-$(config).texinfo might live in

5319 bignums, but don't emit error message.
5321 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
5323 * Makefile.in (targ-cpu.o): Depend on config.h.
5325 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5327 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5328 dropping a space immediately following an identifier.
5329 * expr.c, write.c: Rewrote assert expressions to not use multiple
5330 lines; I don't think that can be done portably.
5331 * config/tc-mips.c (macro): Use $AT if target register is zero in
5332 load instruction, which it can be for a floating point load.
5334 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5355 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5357 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5358 to be on a single line.

5406 prototypes for all static functions. Moved existing minimal
5407 debugging format support info #ifndef OBJ_ECOFF blocks.

5410 all callers accordingly.
5411 (tc_get_register): Renamed from get_register, and made non-static.
5413 * config/mips-big.mt, config/mips-lit.mt: New files. Define

5456 * make-gas.com: Find obstack.obj if it's not in the current
5458 * read.c (s_ignore): Don't declare is_end_of_line. It's
5459 redundant, and triggers a VMS gcc compiler bug.
5461 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5462 current segment as an argument. (Ignored in all cases but VMS.)
5463 All callers and definitions changed.

5594 for now; should be machine-dependent.
5596 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
5597 targets, forcing BFD use.

5760 md_relax_table): Use default zero initialization.
5761 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5762 latter, instead of selecting with preprocessor conditionals.
5764 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5766 * configure.in: recognise all sparclite variants

5776 * expr.c (operand): If character other than comma or newline is a
5777 logical end-of-line character, use the newline case.
5778 From Eric Youngdale:
5779 (operand): Set X_add_number field for floating-point numbers.
5780 (operand): Treat zero byte as end-of-operand.
5782 * configure.in (per-target): Look for with_bfd_assembler option.
5783 For now, only accept "no", until the merge is done.
5785 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5786 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5787 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5788 * read.c: Finish conversion to S_* macros in the VMS only
5789 parts of the program. Add "const" modifier to hex_value.

5792 * expr.c: Add "const" modifier to hex_value.
5793 * symbols.c: Finish conversion to S_* macros in the VMS only
5794 parts of the program. Add "const" modifier to
5795 md_[long,short]_jump_size. Remove declaration of const_flag
5796 (which will be declared in obj-vms.h).
5797 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5798 Fix arguments to VMS_write_object_file.
5799 * config-gas.com: New file. Script for VMS systems to set up the
5800 configuration to build gas for VMS, and create config.status.
5801 * make-gas.com: Redone to work with new scheme.
5802 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5804 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5805 will swap bytes if needed on a big endian system. Use throughout
5807 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5808 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5809 types of malformed stabs. Change parsing algorithm so that we are
5810 more certain of having all of the information that we need on hand.
5811 * obj-vms.c (final_forward_reference): New function, used to help
5812 resolve the data types of as many struct elements as possible
5813 when some part of the struct is not fully defined by the compiler.

5816 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5817 as symbols as well in the object file. Look for external functions
5818 that start with "__vt.", and turn them into variables, since the
5819 g++ compiler is incapable of doing this.
5820 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5822 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5823 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5824 have the name of the source file yet.
5825 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5827 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5829 * read.c (s_data): Always use "data_section", since it'll map to
5830 SEG_DATA or SEG_E1 if needed.
5831 (s_lcomm): Likewise with bss_section.
5832 (s_fill): Use memset, not bzero.
5834 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5855 (section_alignment): Declare only if not BFD_ASSEMBLER.
5856 (big_section, reg_section, pass1_section, diff_section,
5857 absent_section, text_section, data_section, bss_section): If
5858 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5859 mapping to segT enum values.
5860 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5861 if these are used or defined, if BFD_ASSEMBLER.
5862 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5863 subseg_new split into two functions.
5864 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5866 * as.h (volatile): Don't define if already defined.
5867 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5869 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5870 declare with format attribute for -Wformat checking.
5872 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5874 * app.c, config/tc-*.c: Don't include read.h, since it is already
5877 * These are based on patches from Minh Tran-le
5878 <mtranle@paris.intellicorp.com>.
5879 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5880 obj_format coffbfd and gas_target i386coff for target.
5881 (i[34]86-*-isc*): New host (uses sysv).
5882 * config/i386aix.mt: Removed (no longer used).
5883 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5885 (LDFLAGS): Added, defined as -shlib.
5886 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5887 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5888 (DOT_LABEL_PREFIX): Define.
5889 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5890 name rather than L0\001.
5891 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5893 * symbols.c, symbols.h (local_bss_counter): Removed.
5894 * write.c (write_object_file): bss no longer uses
5895 local_bss_counter. Pass correct data and bss size to
5896 VMS_write_object_file.

5902 (size_section): Restored sanity check.
5903 (do_relocs_for): Base section address on s_paddr rather than
5904 computing it. Adjust a29k R_IHIHALF special case to account for
5905 section paddr (used to require paddr to be zero). If there are no
5906 reclos, set s_relptr to 0. Set relocation size in object_headers.
5907 (fill_section): Always set s_vaddr here, removing
5908 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5909 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5910 Set STYP_INFO for .comment.
5911 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5912 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5914 H_{SET,GET}_* macros.
5915 (do_linenos_for): Set lineno size in object_headers.
5916 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5917 set s_vaddr here. If string_byte_count remains 4, set it back to
5918 0, and only write strings out if there are some. Call
5919 fill_section before do_relocs_for and do_linenos_for.
5920 (obj_coff_section): Handle optional quoted second argument giving
5921 section characteristics.
5922 (obj_coff_bss): Added to handle .bss.
5923 (obj_coff_ident): Added to handle .ident (puts string in .comment

5943 (do_scrub_next_char): For \", return " not '.
5944 (symbol_chars): Now const.
5946 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5947 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5949 * config/obj-coff.h: Don't use #elif.
5951 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5952 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5954 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5956 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5978 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5979 using ZERO_BASED_SEGMENTS.
5980 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5981 never set segment address for SEG_E2 (.bss) and don't write out
5982 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5983 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5984 definitions, and don't merge tags with non-tags. Check for .bf
5985 rather than just checking whether the second character is b and
5986 the third character is f.
5987 (obj_coff_val): gcc can generate values which we don't handle
5988 correctly; discard information for now, since it only affects the
5989 debugging information.

5991 (yank_symbols): Don't merge labels.
5992 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6047 options. Updated options documentation for m68k. Some minor
6048 wording/punctuation changes.

6102 xrealloc from xrealloc.c.
6103 * xrealloc.c: Deleted.
6104 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
6106 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
6109 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
6111 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;

6130 * all files: Whitespace changes for GNU indentation style, done by
6131 GNU `indent'. Some cleanup still needed, especially of comments.
6133 * configure.in: No te-386bsd.h file exists; don't try to use it.
6135 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
6137 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
6138 could be doing emulation.
6140 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6143 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6170 consistently const, and always initialized them. Included read.h.
6172 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6174 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6175 constant will not fit in an immediate field.
6176 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
6178 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
6180 * obj-coff.c (callj_table): Delete global variable.

6195 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
6196 so widening works consistently.
6198 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
6200 * version.c: Put conditional "const" before version_string, not
6201 before dummy function for VMS. Now version 1.91.03.
6203 * app.c (do_scrub_next_char): Need double-\ before `000' to show
6204 printed rep of null character.
6206 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
6208 * obj-coffbfd.c (write_object_file): check return value of
6211 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6213 * Support for i386-sysv.
6214 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
6215 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
6216 be used to set them all to zero as was done before.
6217 (fill_section): segment addresses now set in write_object_file.
6218 (fill_section): Don't set STYP_NOLOAD for .bss section.
6219 (fixup_segment): 386 uses strange common symbol format.
6220 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
6221 compatibility with SVR3.2 linker.
6222 * configure.in: i386-sysv and i386-sco use coffbfd.
6224 * app.c (do_scrub_next_char): discard whitespace after a label.

6238 * tc-m68k.c (get_num): make it work for all segments, not just the
6241 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
6243 * configure.in: recognize i386-*-bsd emulation.

6252 * tc-z8k.c: lots of bug fixes
6254 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6256 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6257 #elif, since it is not supported by old compilers.
6258 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6259 couple of expressions in tc-m68k.c.
6261 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6263 * read.c (cons): If NO_RELOC is defined, use it.
6265 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6267 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6269 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6270 local labels to start with a .) and set REGISTER_PREFIX to %.
6271 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6273 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

6287 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6289 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6290 sections starting from zero, rather than making them consecutive.
6291 This makes subsequent reloc calculations easier, esp if the object
6292 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6293 allocate lcomm in .data rather than in .bss. It seems that some
6294 tools can't cope with a non-zero sized bss before linkage.
6296 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6298 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6299 throughout. That enum no longer means what we thought it meant.

6315 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6317 * Makefile.in (install): if $(tooldir) exists, install as in
6320 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6322 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6323 .word is < -32768 or > 32767. The -J flag causes the error to be
6324 ignored. This is to catch over-sized switches generated by gcc on
6325 systems which don't support the broken .word hack.
6326 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6327 write.c (fixup_segment): check for signed .word overflow if
6328 WARN_SIGNED_OVERFLOW_WORD.
6330 * write.c (fixup_segment): fixed missing parens in expression
6331 checking for byte or word overflow.
6333 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

6345 * tc-i386.h : new coff defines
6347 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6349 * input-scrub.c (input_scrub_push): call input_file_begin, not
6351 messages.c (as_perror): print ": " between the passed in error and
6352 the strerror, like perror does.
6354 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6356 * Makefile.in: use gas_target instead of modifying target_cpu.
6357 From Steve Chamberlain:
6358 Makefile.in: Handle m68*-*-coff*.
6359 read.c, read.h: add mult argument to s_space
6361 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6362 Motorola and MIT syntax; gas can now assemble either type of
6364 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
6365 From Steve Chamberlain:
6366 m68kcoff.mt: for m68k COFF.
6367 obj-coffbfd.c: (fixup_mdeps) added

6370 (write_object_file) call fixup_mdeps
6371 (fixup_segment) set fx_subsy to 0.
6372 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6374 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6377 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6379 * Makefile.in (LIBS): Include opcode library.
6381 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
6383 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers

6401 tc-i960.c (md_ri_to_chars): Always output bout object file in
6402 little endian byte order (used to use endianness of host).
6404 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6406 * config/tc-m68k.c (init_table): Now const. Always include 68851
6407 data, so that "bc" is available to 68040 cache instructions.
6408 Added "tt0", "tt1", and 68ec030 variants.
6409 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6410 (enum _register): Added TT0, TT1.
6411 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6412 line number correctly in "internal error" messages. Don't print
6413 architecture-mismatch message for operand errors.
6415 From Colin Smith (colin@wrs.com):
6416 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6417 than install_operand.

6421 * listing.c (buffer_line): rewind to the start of include
6422 files, they might be included twice.

6429 one element of a family.
6431 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
6433 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6434 so that we can assemble hand-written libgcc code.
6436 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6438 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6439 has already been formatted (but may still contain %-characters).
6442 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6444 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6445 written with indirection on the last two operands, which can be
6446 either data or address registers. Added a new operand type 'r'
6447 which accepts either register type. Added '(' to notend stuff in
6448 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6450 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

6463 defined, call it. Change segments before calling fixup_segment.
6464 (relax_align): If linkrelax, provide extra padding.
6466 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6467 their not having symbols associated.
6469 * tc-i960.c (norelax, instrument_branches): Default initializer is
6471 (linkrelax): Delete variable definition.

6494 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
6495 being used with args swapped, causing occasional lossage when
6496 refilling buffers after an include file.
6498 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
6500 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6501 version. Discard bogus DONTDEF version.
6502 (as_warn, as_bad, as_fatal): Likewise.
6504 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
6506 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6507 selected architecture, print a message saying so and listing what
6508 processors support it, rather than saying "operands mismatch".

6525 if TN_SUN3; otherwise align to 2**N-byte bounary.
6527 Thu Aug 6 12:10:39 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6529 * read.c (s_fill): make the .fill size clamped error a warn and
6530 fix bug where 0's were always placed.
6532 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
6533 two bytes of any constant with 0xff:

6537 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
6538 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.

6548 fx_offset into account.
6550 Fri Jul 31 21:53:28 1992 Ken Raeburn (raeburn@cygnus.com)
6552 * configure.in (mips host): Accept "ultrix" with version number.
6554 * expr.c (floating_constant): Separate "=-" to avoid confusing
6555 ancient or broken compilers.
6557 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
6558 processor/opcode mismatch, so reword the error message.
6559 (md_assemble): If no CPU has been set (even if FPU/PMMU
6560 characteristics have been), default to 68020. Don't need extra
6561 quotes around error string.
6563 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6565 * read.c (potable): Revert sac's incorrect change made Jul 13.

6643 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6645 * write.c (write_object_file): keep the fix_tail clean, which
6646 fixes a bug in -R where relocations were being lost.

6695 start addresses to match required alignment.
6697 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6699 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6700 where gcc looks for it.
6702 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6704 * Makefile.in: Changed some lines to be less confusing for some

6770 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6772 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6774 * expr.c (operand): if can't work out what sort of operand it is,
6775 then look through FLT_CHARS for a hint.
6777 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6779 * Makefile.in, configure.in: removed traces of namesubdir,
6780 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6781 copyrights to '92, changed some from Cygnus to FSF.
6783 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6784 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6785 copyrights to '92, changed some from Cygnus to FSF.
6787 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6789 * expr.c: If an expression is single comma, then return with
6790 SEG_ABSENT rather than an error - since the sparc front end does
6791 really strange things with things like fbge,a
6793 * as.h: include bfd.h if using many sections
6794 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6795 local labels didn't work.
6796 * listing.c (list_symbol_table): don't core dump when there's no
6798 * write.c, write.h: call fix_new with the right number of args on
6800 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6803 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6805 * app.c: MRI compatibility - allow single quote to start a string.
6806 * as.c: fix typo recently introduced.
6807 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6808 * expr.c: Much rewriting, to accomodate MRI syntax for
6809 expressions. Also easier to read now.
6810 * listing.c: Put back defuns
6811 * read.c: modified to accept MRI syntax, put back listing pseudo
6812 ops so that an assembler built with NO_LISTING ignores list ops
6814 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6815 machine is a SPARC or a 29K.
6816 * config/obj-aout.c: added s_sect pseudo op
6817 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6818 fill in the timestamp.
6819 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6820 anymore, define all the relocs which the tc-<x> bit will use so we
6821 can translate from them to the coff types.
6822 * config/tc-a29k.c: reloc_type isn't ane enum any more
6823 * config/tc-m68k.c: Added NO_RELOC definition.
6825 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6827 * Makefile.in: put header files before C source for TAGS; remove
6828 references to non-existent syscalls.h.
6830 * read.c, write.c subsegs.c: back out the .bss changes.
6832 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6834 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6838 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6840 * symbols.c (local_label_name): symbols now start with ^A.
6842 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6843 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6844 generate these sections. .align: will use NOP_OPCODE or 0
6845 for padding. This is just for being nice to the
6848 * expr.c (operand): changed to generate local label "\001L0"
6849 starting with a ^A so that it is recognized as a local label.
6851 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6853 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6854 i/o opcodes - inb, inw, outb and outw. string manipulation with
6855 att syntax - scmp, slod, smov, ssca, ssto.
6857 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6858 to just after .file .
6860 In obj_crawl_symbol_chain() where it tries to put the external
6861 symbols apart, with the condition:
6862 (!S_IS_DEFINED(symbolP) &&
6863 !S_IS_DEBUG(symbolP) &&
6864 !SF_GET_STATICS(symbolP))
6865 it was moving too many symbols out. So I switch it back to the
6867 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6869 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6870 so that we don't use the F_RELFLG which make the linker complain
6871 that somebody has stripped the relocation info.
6873 Also, the AIX ld program require that the relocation table
6874 is sorted by r_vaddr like the standard ATT assembler does.
6876 [he also changed the sizeof(struct ...)'s into the coff
6877 style FOOSZ macros. I'm not sure this is right, but I can't
6878 remember why. xoxorich.]
6880 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6882 * Makefile.in, configure.in, doc: use the doc. Build it, install

6887 * read.c: white space and comments only.
6889 * configure.in: use the new atof-ns32.c for ns32k.
6891 * write.c: comment change only.
6893 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6894 aren't yet integrated.
6896 * tc-i860.[hc]: blew off the dust. Something must still be done
6897 about conflicting relocation types.
6899 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6902 * tc-i960.c, tc-sparc.c: white space and comments only.
6904 * tc-a29k.h: delete duplicate macro definition.
6906 * new file atof-ns32k.c copied from hack's last unreleased gas.
6908 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6910 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6913 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6914 ChangeLog's prior to this are sketchy at best. I have logs.
6915 They just aren't ChangeLogs.
6919 version-control: never
