490 reloc->address; another gruesome hack to get gas reloc handling to
493 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
495 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
498 (emit_insn): New function.
499 (md_assemble): Call it.
500 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
502 (lituse_pending): New variable. Set by anything that generates a
503 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
504 tested by code that might want to emit a LITUSE reloc.
505 (emit_unaligned_io): New function. Currently calls md_assemble,
506 but it should eventually be converted to generate the insn itself
507 and call emit_insn directly.
508 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
509 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
510 emit_bis_r): Likewise.
511 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
512 (alpha_ip, label get_macro): Don't emit the final instruction if
514 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
515 unaligned memory access macros.
516 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
517 the value can't be resolved.
519 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
521 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
522 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
523 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
525 (mips_force_relocation): New function.
526 (md_apply_fix): Set fixP->fx_done appropriately.
527 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

535 * config/tc-mips.c (enum mips_pic_level): New enum.
536 (mips_pic): Change from int to enum mips_pic_level. Change all
537 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
538 (load_address): Handle EMBEDDED_PIC.
539 (macro): Handle EMBEDDED_PIC in all PIC cases.
540 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
541 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
542 -non_shared to use NO_PIC (this is how the Irix 5 assembler
543 works). Do not permit -G with SVR4_PIC.
544 (s_abicalls): Warn if -G was used, and force -G 0.
545 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
546 anything but a.out, not just for ELF. For ECOFF, don't generate a
547 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
549 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
551 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
553 * config/tc-hppa.c (create_new_space): Use ints, not chars as
554 parameters to avoid losing when compiling with HP CC.

557 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
559 * Makefile.in (config-stamp): If `defs' is defined, emit a
560 preprocessor directive to create a macro named by this value into
561 config.new; don't explicitly go for BFD_ASSEMBLER.
562 * configure.in: Define `defs', not `BFDDEF'. Set it to
563 MANY_SEGMENTS for any obj-coffbfd target.
564 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
565 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
567 (LOCAL_LOADLIBES): Deleted.
568 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
569 * config/m88kcoff.mt (TDEFINES): Ditto.

572 * config/ic960coff.mt: Deleted.
573 * config/sparc.mt: Deleted.

595 bfd_set_symtab is called.
596 (dump_section_relocs): Note whether a symbol is a section symbol
598 (adjust_reloc_syms): For now, always supply an absolute symbol for
599 fixups without symbols but not yet `done'. Use section_symbol to
600 get the symbol, instead of going directly for abs_symbol.
601 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
602 reloc is not a section symbol and is not in the symbol table.
603 (set_symtab): New function, broken out from write_object_file.
604 Counts symbol table instead of relying on an earlier count.
605 (write_object_file): Call set_symtab, but do it after potentially
606 invoking the *_frob_file macros. Don't bother counting symbols.
607 Call symbol_remove, instead of expanding it in place. Moved the
608 conditionalized `object_file_size' declaration down to
609 conditionalized block where it's used. When using the absolute
610 symbol for a fixup without a symbol, set sy_used_in_reloc.
611 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
612 the correct symbol for the absolute section.
614 * subsegs.c (section_symbol): Use symbol_new instead of
615 symbol_make, since we may want it to go into the symbol table.
616 Make the new symbol have internal linkage. If
617 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
618 symbol with the newly created GAS symbol.
619 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
620 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

625 (in_signed_range): New function.
627 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
628 (sparc_ip, label "immediate"): Reject constants for pcrel
629 instructions only if the relocation type indicates a "call"
630 instruction and the offset is within range of a "jmpl %g0". If
631 it's not in range, use the absolute section symbol plus an offset.
632 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
634 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
636 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
639 * configure.in: Eliminated all targets using obj-coff but not
640 defining BFD_ASSEMBLER; I think all such targets that are
641 supported will be matched by real CPU-OS combinations earlier in
643 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
644 some comments about the dpx2 configuration, but left it disabled,
645 since it couldn't be reached before.
646 (target a29k-amd-ebmonold): Deleted.
648 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
650 * config/tc-hppa.c (pa_import): Correctly handle importing of an
651 already defined symbol.

656 the 'j' operand if there are no further alternatives for this
659 * config/obj-coffbfd.c (adjust_stab_section): Initialize
660 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
661 is not SEG_UNKNOWN rather than checking whether it is >= 0.
663 * config/tc-mips.c (mips_align): Take new argument, label, and use
664 it instead of global insn_label.
665 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
666 call to mips_emit_delay and pass it to mips_align.
668 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
670 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
672 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
673 argument to a .callinfo directive. Don't loop forever on errors.
675 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
676 use pre-defined registers as arguments.
678 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
680 * write.c (write_object_file): Check both S_IS_LOCAL and
681 S_IS_EXTERNAL when deciding whether to discard a symbol.
683 * config-gas.com: Scan Makefile.in, not version.c, for current
684 version number. Delete all versions of temp files when finished
685 with them. Create config.h.
687 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
688 values to reduce number of lookups with S_GET_VALUE. Skip debug

690 holger@botbso.rhein-main.de.)
691 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
692 field. (Also from Holger Teutsch.) Watch for a would-be register
693 mask that spans frags.
695 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
696 this_base, not line_base. (Patch from Andreas Arens,
697 ari@obelix.av.rwth-aachen.de.)
699 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
700 look local if they're exported or undefined. Used to be done for
703 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
704 Get it from the looked-up symbol, instead of using the string from
705 the input stream, which is no longer null-terminated.

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

771 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
772 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

2840 * read.c (next_char_of_string): Limit octal character constants to
2843 * config/tc-hppa.h: Major cleanup. Use GNU-style comments. Warn
2844 against placing additional object-file dependent code here. Warn
2845 against contaminating all of GAS with the internals of tc-hppa.c
2846 through inclusion of tc-hppa.h. Delete all forward declarations
2847 for functions only used within tc-hppa.c, likewise for structures,
2848 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2849 conditional code in a few small places.
2851 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2852 structures, global variables, forward declarations together.

2854 conditional code -- try to group conditional code together
2855 into a few places. Make all functions and variables which
2856 are only used within tc-hppa.c static. PARAMize all functions.
2857 Add comments to functions. Delete unused functions, variables,
2858 #defines, etc. Delete unused members within structures. Delete
2859 ldil;ble hacks -- it is believed they were installed to work
2860 around old gas bugs. Avoid using mixed case for local
2861 functions, variables, and structures. Fix formatting problems
2862 not found by GNU-indent. Add FIXME notices for things which
2863 should be worked on the near future. Delete lots of old
2864 useless (1.36 PA-SOM) code.

2893 a multiple of the section alignment rather than always a
2896 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

4007 * Extensive changes to permit symbols to contain any expression
4008 type and to delay the computation of the expression until the
4009 value is actually needed. This permits setting symbols to values
4010 calculated based on object code size. Expressions were changed to
4011 no longer be in a section, to stop the overloading of segment and
4012 expression type that previously occurred.
4014 * as.c (big_section, pass1_section, diff_section, absent_section):
4016 (expr_section): Added (used for dummy symbols which hold

4102 to pop back to it. Handle unquoted section name as well as quoted
4103 section name. Don't crash on invalid strings.

4125 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
4126 calculating opP->isiz; this permits the expression size to be
4127 determined as well, later on.
4129 * expr.c (clean_up_expression): Don't cancel the subtraction of
4132 * read.c (s_data), config/obj-coffbfd.c (obj_coff_data): If -R,

4141 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
4143 * read.c (float_cons): Simplified parsing logic. If
4144 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.
4146 * symbols.c (colon): Rather than a special case for TC_HPPA,
4147 use new macro tc_frob_label.
4148 * config/tc-hppa.h (tc_frob_label): Define.
4150 * config/tc-mips.c: Many changes to support simple assembler

5306 source directory, if that's not the current directory.

5334 avoid some redefinition complaints on some systems.
5335 (const, volatile): Don't need these conditionally defined if we
5336 use CONST and VOLATILE from ansidecl.h.
5337 (seg_name): Use CONST, not const.
5339 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5341 * config/tc-mips.c: Reindented to GNU standards.

5352 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5354 * Makefile.in: add dvi target; as-$(config).texinfo might live in

5374 * Makefile.in (targ-cpu.o): Depend on config.h.
5376 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5378 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5379 dropping a space immediately following an identifier.

5381 lines; I don't think that can be done portably.
5382 * config/tc-mips.c (macro): Use $AT if target register is zero in
5383 load instruction, which it can be for a floating point load.
5385 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5406 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5408 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5409 to be on a single line.

5457 prototypes for all static functions. Moved existing minimal
5458 debugging format support info #ifndef OBJ_ECOFF blocks.

5507 * make-gas.com: Find obstack.obj if it's not in the current
5509 * read.c (s_ignore): Don't declare is_end_of_line. It's
5510 redundant, and triggers a VMS gcc compiler bug.
5512 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5513 current segment as an argument. (Ignored in all cases but VMS.)
5514 All callers and definitions changed.

5811 md_relax_table): Use default zero initialization.
5812 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5813 latter, instead of selecting with preprocessor conditionals.
5815 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5817 * configure.in: recognise all sparclite variants

5827 * expr.c (operand): If character other than comma or newline is a
5828 logical end-of-line character, use the newline case.
5829 From Eric Youngdale:
5830 (operand): Set X_add_number field for floating-point numbers.
5831 (operand): Treat zero byte as end-of-operand.
5833 * configure.in (per-target): Look for with_bfd_assembler option.
5834 For now, only accept "no", until the merge is done.
5836 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5837 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5839 * read.c: Finish conversion to S_* macros in the VMS only
5840 parts of the program. Add "const" modifier to hex_value.
5841 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5843 * expr.c: Add "const" modifier to hex_value.
5844 * symbols.c: Finish conversion to S_* macros in the VMS only
5845 parts of the program. Add "const" modifier to
5846 md_[long,short]_jump_size. Remove declaration of const_flag
5847 (which will be declared in obj-vms.h).
5848 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5849 Fix arguments to VMS_write_object_file.
5850 * config-gas.com: New file. Script for VMS systems to set up the
5851 configuration to build gas for VMS, and create config.status.
5852 * make-gas.com: Redone to work with new scheme.
5853 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5855 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5856 will swap bytes if needed on a big endian system. Use throughout
5858 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5859 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5860 types of malformed stabs. Change parsing algorithm so that we are
5861 more certain of having all of the information that we need on hand.
5862 * obj-vms.c (final_forward_reference): New function, used to help
5863 resolve the data types of as many struct elements as possible
5864 when some part of the struct is not fully defined by the compiler.

5867 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5868 as symbols as well in the object file. Look for external functions
5869 that start with "__vt.", and turn them into variables, since the
5870 g++ compiler is incapable of doing this.
5871 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5873 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5874 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5875 have the name of the source file yet.
5876 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5878 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5880 * read.c (s_data): Always use "data_section", since it'll map to
5881 SEG_DATA or SEG_E1 if needed.
5882 (s_lcomm): Likewise with bss_section.
5883 (s_fill): Use memset, not bzero.
5885 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5907 (big_section, reg_section, pass1_section, diff_section,
5908 absent_section, text_section, data_section, bss_section): If
5909 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5910 mapping to segT enum values.
5911 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5912 if these are used or defined, if BFD_ASSEMBLER.
5913 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5914 subseg_new split into two functions.
5915 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5917 * as.h (volatile): Don't define if already defined.
5918 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5920 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5921 declare with format attribute for -Wformat checking.
5923 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5925 * app.c, config/tc-*.c: Don't include read.h, since it is already
5928 * These are based on patches from Minh Tran-le
5929 <mtranle@paris.intellicorp.com>.
5930 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5931 obj_format coffbfd and gas_target i386coff for target.
5932 (i[34]86-*-isc*): New host (uses sysv).
5933 * config/i386aix.mt: Removed (no longer used).
5934 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5936 (LDFLAGS): Added, defined as -shlib.
5937 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5938 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5939 (DOT_LABEL_PREFIX): Define.
5940 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5941 name rather than L0\001.
5942 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5944 * symbols.c, symbols.h (local_bss_counter): Removed.
5945 * write.c (write_object_file): bss no longer uses

5953 (size_section): Restored sanity check.
5954 (do_relocs_for): Base section address on s_paddr rather than
5955 computing it. Adjust a29k R_IHIHALF special case to account for
5956 section paddr (used to require paddr to be zero). If there are no
5957 reclos, set s_relptr to 0. Set relocation size in object_headers.
5958 (fill_section): Always set s_vaddr here, removing
5959 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5960 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5961 Set STYP_INFO for .comment.
5962 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5963 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5965 H_{SET,GET}_* macros.
5966 (do_linenos_for): Set lineno size in object_headers.
5967 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5968 set s_vaddr here. If string_byte_count remains 4, set it back to
5969 0, and only write strings out if there are some. Call
5970 fill_section before do_relocs_for and do_linenos_for.
5971 (obj_coff_section): Handle optional quoted second argument giving
5972 section characteristics.
5973 (obj_coff_bss): Added to handle .bss.
5974 (obj_coff_ident): Added to handle .ident (puts string in .comment

5994 (do_scrub_next_char): For \", return " not '.
5995 (symbol_chars): Now const.
5997 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5998 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6000 * config/obj-coff.h: Don't use #elif.
6002 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6003 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
6005 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
6007 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

6027 SEG_BSS, fill with NOP_OPCODE.
6028 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
6029 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6030 using ZERO_BASED_SEGMENTS.
6031 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6032 never set segment address for SEG_E2 (.bss) and don't write out
6033 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6034 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6035 definitions, and don't merge tags with non-tags. Check for .bf
6036 rather than just checking whether the second character is b and
6037 the third character is f.
6038 (obj_coff_val): gcc can generate values which we don't handle
6039 correctly; discard information for now, since it only affects the
6040 debugging information.
6041 (tag_find_or_name): Don't insert tags in the symbol table.
6042 (yank_symbols): Don't merge labels.
6043 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6063 power-of-two alignment for .align.
6065 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
6066 and leave everything else alone.

6189 could be doing emulation.
6191 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6194 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6223 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6225 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6226 constant will not fit in an immediate field.
6227 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

6264 * Support for i386-sysv.
6265 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6305 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6307 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6308 #elif, since it is not supported by old compilers.
6309 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6310 couple of expressions in tc-m68k.c.
6312 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6314 * read.c (cons): If NO_RELOC is defined, use it.
6316 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6318 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6320 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6321 local labels to start with a .) and set REGISTER_PREFIX to %.
6322 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6324 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

6338 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6340 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6341 sections starting from zero, rather than making them consecutive.
6342 This makes subsequent reloc calculations easier, esp if the object
6343 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6344 allocate lcomm in .data rather than in .bss. It seems that some
6345 tools can't cope with a non-zero sized bss before linkage.
6347 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6349 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

6368 * Makefile.in (install): if $(tooldir) exists, install as in
6371 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6373 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6374 .word is < -32768 or > 32767. The -J flag causes the error to be
6375 ignored. This is to catch over-sized switches generated by gcc on
6376 systems which don't support the broken .word hack.
6377 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6378 write.c (fixup_segment): check for signed .word overflow if
6379 WARN_SIGNED_OVERFLOW_WORD.
6381 * write.c (fixup_segment): fixed missing parens in expression
6382 checking for byte or word overflow.

6398 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6400 * input-scrub.c (input_scrub_push): call input_file_begin, not
6402 messages.c (as_perror): print ": " between the passed in error and
6403 the strerror, like perror does.

6408 From Steve Chamberlain:
6409 Makefile.in: Handle m68*-*-coff*.
6410 read.c, read.h: add mult argument to s_space
6412 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6413 Motorola and MIT syntax; gas can now assemble either type of
6415 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6421 (write_object_file) call fixup_mdeps
6422 (fixup_segment) set fx_subsy to 0.
6423 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6425 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6428 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6430 * Makefile.in (LIBS): Include opcode library.
6432 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6453 little endian byte order (used to use endianness of host).
6455 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6457 * config/tc-m68k.c (init_table): Now const. Always include 68851
6458 data, so that "bc" is available to 68040 cache instructions.
6459 Added "tt0", "tt1", and 68ec030 variants.
6460 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6461 (enum _register): Added TT0, TT1.
6462 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6463 line number correctly in "internal error" messages. Don't print
6464 architecture-mismatch message for operand errors.
6466 From Colin Smith (colin@wrs.com):
6467 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6468 than install_operand.

6484 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6485 so that we can assemble hand-written libgcc code.

6489 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6490 has already been formatted (but may still contain %-characters).
6493 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6495 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6496 written with indirection on the last two operands, which can be
6497 either data or address registers. Added a new operand type 'r'
6498 which accepts either register type. Added '(' to notend stuff in
6499 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6501 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

6517 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6518 their not having symbols associated.
6520 * tc-i960.c (norelax, instrument_branches): Default initializer is
6522 (linkrelax): Delete variable definition.

6546 being used with args swapped, causing occasional lossage when
6547 refilling buffers after an include file.

6551 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6552 version. Discard bogus DONTDEF version.

6557 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6558 selected architecture, print a message saying so and listing what

6609 processor/opcode mismatch, so reword the error message.
6610 (md_assemble): If no CPU has been set (even if FPU/PMMU
6611 characteristics have been), default to 68020. Don't need extra
6612 quotes around error string.

6694 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6696 * write.c (write_object_file): keep the fix_tail clean, which
6697 fixes a bug in -R where relocations were being lost.
6699 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6701 * configure.in: recognize m680x0 as having sun3 emulation mode for

6746 start addresses to match required alignment.
6748 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6750 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6751 where gcc looks for it.
6753 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6755 * Makefile.in: Changed some lines to be less confusing for some

6821 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6823 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6825 * expr.c (operand): if can't work out what sort of operand it is,
6826 then look through FLT_CHARS for a hint.
6828 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6830 * Makefile.in, configure.in: removed traces of namesubdir,
6831 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6832 copyrights to '92, changed some from Cygnus to FSF.
6834 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6835 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6836 copyrights to '92, changed some from Cygnus to FSF.
6838 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6840 * expr.c: If an expression is single comma, then return with
6841 SEG_ABSENT rather than an error - since the sparc front end does
6842 really strange things with things like fbge,a
6844 * as.h: include bfd.h if using many sections
6845 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6846 local labels didn't work.
6847 * listing.c (list_symbol_table): don't core dump when there's no
6849 * write.c, write.h: call fix_new with the right number of args on
6851 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6854 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6856 * app.c: MRI compatibility - allow single quote to start a string.
6857 * as.c: fix typo recently introduced.
6858 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6859 * expr.c: Much rewriting, to accomodate MRI syntax for
6860 expressions. Also easier to read now.
6861 * listing.c: Put back defuns
6862 * read.c: modified to accept MRI syntax, put back listing pseudo
6863 ops so that an assembler built with NO_LISTING ignores list ops
6865 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6866 machine is a SPARC or a 29K.
6867 * config/obj-aout.c: added s_sect pseudo op
6868 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6869 fill in the timestamp.
6870 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6871 anymore, define all the relocs which the tc-<x> bit will use so we
6872 can translate from them to the coff types.
6873 * config/tc-a29k.c: reloc_type isn't ane enum any more
6874 * config/tc-m68k.c: Added NO_RELOC definition.
6876 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6878 * Makefile.in: put header files before C source for TAGS; remove
6879 references to non-existent syscalls.h.
6881 * read.c, write.c subsegs.c: back out the .bss changes.
6883 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6885 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6889 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6891 * symbols.c (local_label_name): symbols now start with ^A.
6893 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6894 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6895 generate these sections. .align: will use NOP_OPCODE or 0
6896 for padding. This is just for being nice to the
6899 * expr.c (operand): changed to generate local label "\001L0"
6900 starting with a ^A so that it is recognized as a local label.
6902 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6904 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6905 i/o opcodes - inb, inw, outb and outw. string manipulation with
6906 att syntax - scmp, slod, smov, ssca, ssto.
6908 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6909 to just after .file .
6911 In obj_crawl_symbol_chain() where it tries to put the external
6912 symbols apart, with the condition:
6913 (!S_IS_DEFINED(symbolP) &&
6914 !S_IS_DEBUG(symbolP) &&
6915 !SF_GET_STATICS(symbolP))
6916 it was moving too many symbols out. So I switch it back to the
6918 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6920 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6921 so that we don't use the F_RELFLG which make the linker complain
6922 that somebody has stripped the relocation info.
6924 Also, the AIX ld program require that the relocation table
6925 is sorted by r_vaddr like the standard ATT assembler does.
6927 [he also changed the sizeof(struct ...)'s into the coff
6928 style FOOSZ macros. I'm not sure this is right, but I can't
6929 remember why. xoxorich.]
6931 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6933 * Makefile.in, configure.in, doc: use the doc. Build it, install
6936 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6938 * read.c: white space and comments only.
6940 * configure.in: use the new atof-ns32.c for ns32k.
6942 * write.c: comment change only.
6944 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6945 aren't yet integrated.
6947 * tc-i860.[hc]: blew off the dust. Something must still be done
6948 about conflicting relocation types.
6950 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6953 * tc-i960.c, tc-sparc.c: white space and comments only.
6955 * tc-a29k.h: delete duplicate macro definition.
6957 * new file atof-ns32k.c copied from hack's last unreleased gas.
6959 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6961 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6964 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6965 ChangeLog's prior to this are sketchy at best. I have logs.
6966 They just aren't ChangeLogs.
6970 version-control: never
