109 * config/obj-coff.c (coff_frob_symbol): Use C_STAT for the .text
110 section symbol, not C_LABEL.
112 * config/tc-mips.c (mips_ip): Permit a modifier in 'o' case, and

164 * read.c (emit_expr): Use memset to zero out memory, rather than
165 going through md_number_to_chars. This permits handling symbolic
166 arguments when the size is larger than sizeof (valueT), if
167 TC_CONS_FIX_NEW is prepared to handle the case (as it is on MIPS).

219 (control_regs): New pointer.
220 (m68k_ip): Use control_regs instead of testing CPU every time.

512 * listing.c (list_symbol_table): Print "NO DEFINED SYMBOLS" and
513 "NO UNDEFINED SYMBOLS" if there aren't any, instead of displaying
514 the header with an empty list.
516 * config/obj-coffbfd.c (fill_section): Check COFF_NOLOAD_PROBLEM
517 also before setting STYP_NOLOAD for .bss section.

537 Define as macros instead of enumerators, since the Apollo compiler
538 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum

545 [TE_APOLLO] (OBJ_COFF_OMIT_OPTIONAL_HEADER): Undefine. That is,
546 do include the optional header for Apollo target.
547 (COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
549 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
550 can be used within a label name.
552 * config/tc-m68k.h (m68k_init_after_args): Declare.
553 (tc_init_after_args): Define as m68k_init_after_args.
554 * config/tc-m68k.c (m68k_init_after_args): New function,

576 * listing.c (list_symbol_table): Don't print register symbols as
579 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
580 underscores, since symbol_new will already have done it.
581 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
583 * as.c (main): If tc_init_after_args is defined, invoke it after
584 all arguments have been processed.

587 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
588 section instead of .text. Call create_target_segments.
589 * read.c (demand_copy_string): No longer static.

593 * config/tc-mips.c (append_insn): Permit branches to be switched
594 with the preceding instruction even if .set nobopt has been seen.
595 .set nobopt actually controls whether to bring up an instruction
596 from the branch target, which gas does not currently support.

614 multiple of alignment power specified in bfd target vector.
616 * gasp.c: Include ctype.h.

654 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
656 * expr.c (operand): Try to parse "0f" and "0b" sequences as
657 floating point and binary numbers respectively; if it doesn't
658 work, treat them as local labels.
660 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
661 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
663 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
665 * vmsconf.sh: In generated file, get ".obj" suffix right, build
666 source files from other directories into objects in the current
667 directory, and specify PSECT attributes explicitly to linker.
668 Also added missing label.
669 * Makefile.in (stamp-mk.com): Reference new variable
670 VMS_OTHER_OBJS for list of non-local object files, instead of

687 argument, the reloc type.
688 (load_register): Pass reloc type to macro_build for 'u'.
689 (macro): Likewise. For M_LA_AB permit a difference expression
690 when generating embedded PIC code between an arbitrary symbol and
691 a symbol in the .text section.

733 (hppa_tc_symbol): Likewise.
735 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
736 elf_tc_make_sections stuff. It was there to support PA braindamage
737 which has been fixed, and in the case of elf_tc_make_sections is
738 redundant with elf_tc_final_processing.
740 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
742 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

752 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
753 value into the file if the fixup will not generate a reloc.
755 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
757 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
758 don't spew remainder of input file in error message.
759 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
760 message with reloc type and try to process remainder of file.
762 * doc/Makefile.in (install-info-as, install-info-gasp): New
763 targets, now explicitly checking $(srcdir) for info files.
764 (install-info): Depend on both of them; do nothing more.
766 Mon Apr 4 17:06:04 1994 Jeffrey A. Law (law@cygnus.com)
768 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
770 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
772 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
773 flag rather than signedp field. Only permit extended range if
774 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
775 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
777 * config/tc-ppc.c (ppc_size): New static variable.
778 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
779 (md_begin): If an instruction has a size specific flag set, only
780 add it if we are assembling that size.
782 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
784 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
785 cross section PC relative relocs right for COFF and ELF.
787 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
789 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

800 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
801 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
802 and -many (all architectures).

813 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
815 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
816 branch with an instruction that uses $at, in case the branch is
818 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
819 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
820 to make it pcrel_offset.
821 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
822 reloc->address; another gruesome hack to get gas reloc handling to
825 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
827 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using

831 (md_assemble): Call it.
832 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
834 (lituse_pending): New variable. Set by anything that generates a
835 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
836 tested by code that might want to emit a LITUSE reloc.
837 (emit_unaligned_io): New function. Currently calls md_assemble,
838 but it should eventually be converted to generate the insn itself
839 and call emit_insn directly.
840 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
841 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
842 emit_bis_r): Likewise.

849 the value can't be resolved.
851 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
853 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
854 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
855 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

869 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
870 (load_address): Handle EMBEDDED_PIC.
871 (macro): Handle EMBEDDED_PIC in all PIC cases.
872 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
873 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
874 -non_shared to use NO_PIC (this is how the Irix 5 assembler
875 works). Do not permit -G with SVR4_PIC.
876 (s_abicalls): Warn if -G was used, and force -G 0.
877 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
878 anything but a.out, not just for ELF. For ECOFF, don't generate a
879 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
881 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
883 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

889 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
891 * Makefile.in (config-stamp): If `defs' is defined, emit a
892 preprocessor directive to create a macro named by this value into
893 config.new; don't explicitly go for BFD_ASSEMBLER.
894 * configure.in: Define `defs', not `BFDDEF'. Set it to
895 MANY_SEGMENTS for any obj-coffbfd target.
896 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
897 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
899 (LOCAL_LOADLIBES): Deleted.
900 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
901 * config/m88kcoff.mt (TDEFINES): Ditto.
902 * config/ebmon29k.mt: Deleted.

904 * config/ic960coff.mt: Deleted.
905 * config/sparc.mt: Deleted.

907 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
908 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

927 bfd_set_symtab is called.
928 (dump_section_relocs): Note whether a symbol is a section symbol
930 (adjust_reloc_syms): For now, always supply an absolute symbol for
931 fixups without symbols but not yet `done'. Use section_symbol to
932 get the symbol, instead of going directly for abs_symbol.
933 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
934 reloc is not a section symbol and is not in the symbol table.
935 (set_symtab): New function, broken out from write_object_file.
936 Counts symbol table instead of relying on an earlier count.
937 (write_object_file): Call set_symtab, but do it after potentially
938 invoking the *_frob_file macros. Don't bother counting symbols.
939 Call symbol_remove, instead of expanding it in place. Moved the
940 conditionalized `object_file_size' declaration down to
941 conditionalized block where it's used. When using the absolute
942 symbol for a fixup without a symbol, set sy_used_in_reloc.
943 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
944 the correct symbol for the absolute section.
946 * subsegs.c (section_symbol): Use symbol_new instead of
947 symbol_make, since we may want it to go into the symbol table.
948 Make the new symbol have internal linkage. If
949 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
950 symbol with the newly created GAS symbol.
951 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
952 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2757 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
2758 standard hpux include files to pick up various function decls.
2760 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

2793 of interest to the linker. ENTRY/EXIT relocations for SOM are
2794 an example of marker relocations.

2823 assuming BFD_RELOC_LO16. Don't try to convert BFD_RELOC_LO16 to
2824 BFD_RELOC_MIPS_GPREL. Added new case a.
2825 (set_at, load_register, macro): Changed calls to macro_build to
2826 pass new argument for i, j and o cases.

3160 OPTIONAL_REGISTER_PREFIX if either is already defined.
3162 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
3164 * configure.in: Set bfd_gas for all sparc targets. Added facility
3165 for keeping or rejecting configurations still under development;
3166 default is to assume production environment, and reject configs
3167 still being worked on. Mark Elf configurations (except sparc and
3168 i386) as developmental. Deleted cases matching some generic names
3169 in favor of more specific names. (E.g., when we get Alpha

3187 for functions only used within tc-hppa.c, likewise for structures,
3188 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
3189 conditional code in a few small places.
3191 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3192 structures, global variables, forward declarations together.

3195 into a few places. Make all functions and variables which
3196 are only used within tc-hppa.c static. PARAMize all functions.
3197 Add comments to functions. Delete unused functions, variables,
3198 #defines, etc. Delete unused members within structures. Delete
3199 ldil;ble hacks -- it is believed they were installed to work
3200 around old gas bugs. Avoid using mixed case for local
3201 functions, variables, and structures. Fix formatting problems
3202 not found by GNU-indent. Add FIXME notices for things which
3203 should be worked on the near future. Delete lots of old
3204 useless (1.36 PA-SOM) code.

3233 a multiple of the section alignment rather than always a
3236 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
3237 bits are zero (eg they specify no relocations), then do not even
3238 bother adding their entries to thesymextn section.

3279 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
3280 call strchr for each character to see if it is a special char,

3282 of text, data and bss sections to 4.
3283 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3285 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3286 ELF, since the ELF object format does not have these type of
3287 relocations. Change the abort into as as_bad and return
3288 BFD_RELOC_NONE to silence compiler warnings.
3289 (md_assemble): Keep track of the instruction size. Allow white
3290 space between the $ and the constant for compatibility with older
3291 gases and other assemblers.

4301 are also magic, and have special default flag settings.
4302 (obj_elf_frob_symbol): Since the return value from this function

4366 * Extensive changes to permit symbols to contain any expression
4367 type and to delay the computation of the expression until the
4368 value is actually needed. This permits setting symbols to values
4369 calculated based on object code size. Expressions were changed to
4370 no longer be in a section, to stop the overloading of segment and
4371 expression type that previously occurred.
4373 * as.c (big_section, pass1_section, diff_section, absent_section):
4375 (expr_section): Added (used for dummy symbols which hold

4459 (previous_section, previous_subsection): New vars.
4460 (obj_elf_section): Save current place in case DWARF code wants us
4461 to pop back to it. Handle unquoted section name as well as quoted
4462 section name. Don't crash on invalid strings.
4463 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

4575 sy_resolved and sy_resolving single bit fields.
4576 * symbols.c (symbol_new): Don't initialize sy_forward field.

5610 than ECOFF line number information.
5611 (obj_ecoff_stab): Accept non-zero values for stabs line number.

5638 references don't appear to work right.
5640 * as.h (const, volatile): Put these definitions back, and use
5643 * doc/as.texinfo: First pass at using new texinfo features --
5644 variables, conditional tests. Far from complete.

5670 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
5671 the bottom (make expands variables in dependencies when the
5672 dependencies are read, not when they are used).
5674 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
5675 a29k .bss section; the mondfe program doesn't like it.

5696 source directory, if that's not the current directory.
5698 * configure.in (per-host): Accept MIPS host with BSD version

5720 process relocs if there aren't any relocs to process. Avoids
5721 malloc/free bug on SCO too.
5723 * as.h: Move local include files below system include files, to
5724 avoid some redefinition complaints on some systems.
5725 (const, volatile): Don't need these conditionally defined if we
5726 use CONST and VOLATILE from ansidecl.h.
5727 (seg_name): Use CONST, not const.
5729 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5731 * config/tc-mips.c: Reindented to GNU standards.
5733 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
5735 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5736 (fixup_segment): Add a29k special case; the linker is not prepared
5737 to see a segment offset here.
5739 * app.c (do_scrub_next_char): Added new state, 10, modifying state
5740 9 to only keep a space in between identifier characters.
5742 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5744 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5745 srcdir, might be in objdir.
5747 * doc/Makefile.in: dvi depends on as.dvi

5765 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
5766 bignums, but don't emit error message.
5768 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
5770 * Makefile.in (targ-cpu.o): Depend on config.h.
5772 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5774 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5775 dropping a space immediately following an identifier.
5776 * expr.c, write.c: Rewrote assert expressions to not use multiple
5777 lines; I don't think that can be done portably.
5778 * config/tc-mips.c (macro): Use $AT if target register is zero in
5779 load instruction, which it can be for a floating point load.
5781 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5792 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
5793 z8k-opc.h, not z8k.h.
5795 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
5798 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5800 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
5802 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5804 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

5853 prototypes for all static functions. Moved existing minimal
5854 debugging format support info #ifndef OBJ_ECOFF blocks.
5855 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
5856 does not support a non sign extended high 16 bits reloc. Adjusted
5857 all callers accordingly.
5858 (tc_get_register): Renamed from get_register, and made non-static.
5860 * config/mips-big.mt, config/mips-lit.mt: New files. Define

5903 * make-gas.com: Find obstack.obj if it's not in the current
5905 * read.c (s_ignore): Don't declare is_end_of_line. It's
5906 redundant, and triggers a VMS gcc compiler bug.
5908 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5909 current segment as an argument. (Ignored in all cases but VMS.)
5910 All callers and definitions changed.

5928 argument to s_ignore. Put "#if 0" around unused code.
5929 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
5930 Call elf_xstabs for .stabs and .xstabs operators.
5932 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
5934 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
5937 * configure.in: mips-bsd configuration was missing format spec.
5940 * Makefile.in (Makefile): Depends on configure.in.
5942 * config/tc-mips.c (append_insn): Don't check for alignment of
5943 frag in memory; alignment of instructions in section is a separate

5963 * config/tc-sparc.c (s_xword): Now call big_cons, so large
5964 constants are accepted, but symbolic values are not. GCC will not
5965 generate the latter currently.
5967 * frags.c (frag_init): New function.
5968 (zero_address_frag, bss_address_frag): Now initialized at run
5970 * as.c (main): Call frag_init.

6014 (fixup_segment): Make sure common-section symbols get treated the
6015 same as undefined symbols.
6016 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type
6017 bfd_reloc_code_real_type. Use seg_fix_{root,tail}P derived from

6046 new section/subsection.
6048 * read.c: Don't include ctype.h.
6049 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
6050 for now; should be machine-dependent.
6052 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
6053 targets, forcing BFD use.

6057 * config/tc-sparc.c: Use PARAMS macro for static function
6058 declarations. Use BFD_RELOC_ macros everywhere, with
6059 compatibility macros declared for non-BFD mode.

6071 of referencing fields directly.
6073 * write.c (cvt_frag_to_fill): New function; extracted from
6075 (write_object_file) [! BFD_ASSEMBLER]: Call it.
6076 (relax_and_size_seg) [BFD_ASSEMBLER]: New function; relax section
6077 and set its size and flags.
6079 * struc-symbol.h (struct symbol) [BFD_ASSEMBLER]: Replace some

6237 * expr.c (operand): If character other than comma or newline is a
6238 logical end-of-line character, use the newline case.
6239 From Eric Youngdale:
6240 (operand): Set X_add_number field for floating-point numbers.
6241 (operand): Treat zero byte as end-of-operand.
6243 * configure.in (per-target): Look for with_bfd_assembler option.
6244 For now, only accept "no", until the merge is done.
6246 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
6247 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
6248 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
6249 * read.c: Finish conversion to S_* macros in the VMS only
6250 parts of the program. Add "const" modifier to hex_value.

6253 * expr.c: Add "const" modifier to hex_value.
6254 * symbols.c: Finish conversion to S_* macros in the VMS only
6255 parts of the program. Add "const" modifier to
6256 md_[long,short]_jump_size. Remove declaration of const_flag
6257 (which will be declared in obj-vms.h).
6258 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6259 Fix arguments to VMS_write_object_file.
6260 * config-gas.com: New file. Script for VMS systems to set up the
6261 configuration to build gas for VMS, and create config.status.
6262 * make-gas.com: Redone to work with new scheme.
6263 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
6265 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
6266 will swap bytes if needed on a big endian system. Use throughout
6268 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
6269 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6270 types of malformed stabs. Change parsing algorithm so that we are
6271 more certain of having all of the information that we need on hand.
6272 * obj-vms.c (final_forward_reference): New function, used to help
6273 resolve the data types of as many struct elements as possible
6274 when some part of the struct is not fully defined by the compiler.

6277 * obj-vms.c (VMS_write_object_file): Define all vtable psects
6278 as symbols as well in the object file. Look for external functions

6280 g++ compiler is incapable of doing this.
6281 * tc-vax.c: Add '1' option for backward compatibility with older GCC
6283 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
6284 * input-scrub.c (as_where): Fix bug where as would crash if we did not
6285 have the name of the source file yet.
6286 * config/ho-vms.h: define HO_VMS, not HO_VAX.
6288 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
6290 * read.c (s_data): Always use "data_section", since it'll map to
6291 SEG_DATA or SEG_E1 if needed.
6292 (s_lcomm): Likewise with bss_section.
6293 (s_fill): Use memset, not bzero.
6295 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

6316 (section_alignment): Declare only if not BFD_ASSEMBLER.
6317 (big_section, reg_section, pass1_section, diff_section,
6318 absent_section, text_section, data_section, bss_section): If
6319 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
6320 mapping to segT enum values.
6321 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
6322 if these are used or defined, if BFD_ASSEMBLER.
6323 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6324 subseg_new split into two functions.
6325 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6327 * as.h (volatile): Don't define if already defined.
6328 (had_errors, had_warnings): Provide prototypes for ANSI C even if
6330 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
6331 declare with format attribute for -Wformat checking.
6333 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
6335 * app.c, config/tc-*.c: Don't include read.h, since it is already
6338 * These are based on patches from Minh Tran-le
6339 <mtranle@paris.intellicorp.com>.
6340 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
6341 obj_format coffbfd and gas_target i386coff for target.
6342 (i[34]86-*-isc*): New host (uses sysv).
6343 * config/i386aix.mt: Removed (no longer used).
6344 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
6346 (LDFLAGS): Added, defined as -shlib.
6347 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
6348 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6349 (DOT_LABEL_PREFIX): Define.
6350 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
6351 name rather than L0\001.

6363 (size_section): Restored sanity check.
6364 (do_relocs_for): Base section address on s_paddr rather than
6365 computing it. Adjust a29k R_IHIHALF special case to account for
6366 section paddr (used to require paddr to be zero). If there are no
6367 reclos, set s_relptr to 0. Set relocation size in object_headers.
6368 (fill_section): Always set s_vaddr here, removing
6369 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6370 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6371 Set STYP_INFO for .comment.
6372 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
6373 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

6375 H_{SET,GET}_* macros.
6376 (do_linenos_for): Set lineno size in object_headers.
6377 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6378 set s_vaddr here. If string_byte_count remains 4, set it back to
6379 0, and only write strings out if there are some. Call
6380 fill_section before do_relocs_for and do_linenos_for.
6381 (obj_coff_section): Handle optional quoted second argument giving
6382 section characteristics.
6383 (obj_coff_bss): Added to handle .bss.
6384 (obj_coff_ident): Added to handle .ident (puts string in .comment

6404 (do_scrub_next_char): For \", return " not '.
6405 (symbol_chars): Now const.
6407 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6408 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6410 * config/obj-coff.h: Don't use #elif.
6412 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6413 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
6415 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
6417 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

6437 SEG_BSS, fill with NOP_OPCODE.
6438 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
6439 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6440 using ZERO_BASED_SEGMENTS.
6441 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6442 never set segment address for SEG_E2 (.bss) and don't write out
6443 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6444 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6445 definitions, and don't merge tags with non-tags. Check for .bf
6446 rather than just checking whether the second character is b and
6447 the third character is f.
6448 (obj_coff_val): gcc can generate values which we don't handle
6449 correctly; discard information for now, since it only affects the
6450 debugging information.
6451 (tag_find_or_name): Don't insert tags in the symbol table.
6452 (yank_symbols): Don't merge labels.
6453 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6508 options. Updated options documentation for m68k. Some minor
6509 wording/punctuation changes.

6591 * all files: Whitespace changes for GNU indentation style, done by
6592 GNU `indent'. Some cleanup still needed, especially of comments.
6594 * configure.in: No te-386bsd.h file exists; don't try to use it.
6596 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
6598 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
6599 could be doing emulation.
6601 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6604 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6631 consistently const, and always initialized them. Included read.h.
6633 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6635 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6636 constant will not fit in an immediate field.
6637 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
6639 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
6641 * obj-coff.c (callj_table): Delete global variable.

6656 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
6657 so widening works consistently.
6659 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
6661 * version.c: Put conditional "const" before version_string, not

6664 * app.c (do_scrub_next_char): Need double-\ before `000' to show
6665 printed rep of null character.
6667 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
6669 * obj-coffbfd.c (write_object_file): check return value of
6672 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6674 * Support for i386-sysv.
6675 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
6676 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
6677 be used to set them all to zero as was done before.
6678 (fill_section): segment addresses now set in write_object_file.
6679 (fill_section): Don't set STYP_NOLOAD for .bss section.
6680 (fixup_segment): 386 uses strange common symbol format.

6699 * tc-m68k.c (get_num): make it work for all segments, not just the
6702 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
6704 * configure.in: recognize i386-*-bsd emulation.

6713 * tc-z8k.c: lots of bug fixes
6715 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6717 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6718 #elif, since it is not supported by old compilers.
6719 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6720 couple of expressions in tc-m68k.c.
6722 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6724 * read.c (cons): If NO_RELOC is defined, use it.
6726 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6728 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6730 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6731 local labels to start with a .) and set REGISTER_PREFIX to %.
6732 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6734 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

6748 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6750 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6751 sections starting from zero, rather than making them consecutive.
6752 This makes subsequent reloc calculations easier, esp if the object
6753 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6754 allocate lcomm in .data rather than in .bss. It seems that some
6755 tools can't cope with a non-zero sized bss before linkage.
6757 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6759 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6760 throughout. That enum no longer means what we thought it meant.

6763 "-mno-688[58]1" options.
6765 * tc-m68k.c: Added CPU32 support.

6774 Change LIBDEPS dependence to LIBS.
6776 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6778 * Makefile.in (install): if $(tooldir) exists, install as in
6781 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6783 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6784 .word is < -32768 or > 32767. The -J flag causes the error to be
6785 ignored. This is to catch over-sized switches generated by gcc on
6786 systems which don't support the broken .word hack.
6787 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6788 write.c (fixup_segment): check for signed .word overflow if
6789 WARN_SIGNED_OVERFLOW_WORD.
6791 * write.c (fixup_segment): fixed missing parens in expression
6792 checking for byte or word overflow.
6794 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
6795 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
6796 WARN_SIGNED_OVERFLOW_WORD.

6804 * obj-coffbfd.h : added stuff
6805 * tc-i386.c (tc_coff_fix2rtype): new function
6806 * tc-i386.h : new coff defines
6808 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6810 * input-scrub.c (input_scrub_push): call input_file_begin, not
6812 messages.c (as_perror): print ": " between the passed in error and
6813 the strerror, like perror does.
6815 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6817 * Makefile.in: use gas_target instead of modifying target_cpu.
6818 From Steve Chamberlain:
6819 Makefile.in: Handle m68*-*-coff*.
6820 read.c, read.h: add mult argument to s_space
6822 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6823 Motorola and MIT syntax; gas can now assemble either type of
6825 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
6826 From Steve Chamberlain:
6827 m68kcoff.mt: for m68k COFF.
6828 obj-coffbfd.c: (fixup_mdeps) added

6831 (write_object_file) call fixup_mdeps
6832 (fixup_segment) set fx_subsy to 0.
6833 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6835 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6838 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6840 * Makefile.in (LIBS): Include opcode library.
6842 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6862 tc-i960.c (md_ri_to_chars): Always output bout object file in
6863 little endian byte order (used to use endianness of host).
6865 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6867 * config/tc-m68k.c (init_table): Now const. Always include 68851
6868 data, so that "bc" is available to 68040 cache instructions.
6869 Added "tt0", "tt1", and 68ec030 variants.
6870 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6871 (enum _register): Added TT0, TT1.
6872 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6873 line number correctly in "internal error" messages. Don't print
6874 architecture-mismatch message for operand errors.
6876 From Colin Smith (colin@wrs.com):
6877 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6878 than install_operand.

6882 * listing.c (buffer_line): rewind to the start of include
6883 files, they might be included twice.

6890 one element of a family.
6892 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
6894 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6895 so that we can assemble hand-written libgcc code.
6897 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6899 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6900 has already been formatted (but may still contain %-characters).
6903 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6905 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6906 written with indirection on the last two operands, which can be
6907 either data or address registers. Added a new operand type 'r'
6908 which accepts either register type. Added '(' to notend stuff in
6909 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6911 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

6923 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
6924 defined, call it. Change segments before calling fixup_segment.
6925 (relax_align): If linkrelax, provide extra padding.
6927 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6928 their not having symbols associated.
6930 * tc-i960.c (norelax, instrument_branches): Default initializer is
6932 (linkrelax): Delete variable definition.

6955 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
6956 being used with args swapped, causing occasional lossage when
6957 refilling buffers after an include file.
6959 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
6961 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6962 version. Discard bogus DONTDEF version.
6963 (as_warn, as_bad, as_fatal): Likewise.

6967 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6968 selected architecture, print a message saying so and listing what

6990 * read.c (s_fill): make the .fill size clamped error a warn and
6991 fix bug where 0's were always placed.
6993 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
6994 two bytes of any constant with 0xff:

6998 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
6999 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.

7013 * configure.in (mips host): Accept "ultrix" with version number.
7015 * expr.c (floating_constant): Separate "=-" to avoid confusing
7016 ancient or broken compilers.
7018 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
7019 processor/opcode mismatch, so reword the error message.
7020 (md_assemble): If no CPU has been set (even if FPU/PMMU
7021 characteristics have been), default to 68020. Don't need extra
7022 quotes around error string.
7024 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
7026 * read.c (potable): Revert sac's incorrect change made Jul 13.

7104 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
7106 * write.c (write_object_file): keep the fix_tail clean, which
7107 fixes a bug in -R where relocations were being lost.

7156 start addresses to match required alignment.
7158 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
7160 * Makefile.in (install): Install into $(tooldir)/bin, since that's
7161 where gcc looks for it.
7163 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
7165 * Makefile.in: Changed some lines to be less confusing for some

7231 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
7233 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
7235 * expr.c (operand): if can't work out what sort of operand it is,
7236 then look through FLT_CHARS for a hint.
7238 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
7240 * Makefile.in, configure.in: removed traces of namesubdir,

7244 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
7245 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
7246 copyrights to '92, changed some from Cygnus to FSF.
7248 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7250 * expr.c: If an expression is single comma, then return with
7251 SEG_ABSENT rather than an error - since the sparc front end does
7252 really strange things with things like fbge,a
7254 * as.h: include bfd.h if using many sections
7255 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
7256 local labels didn't work.
7257 * listing.c (list_symbol_table): don't core dump when there's no
7259 * write.c, write.h: call fix_new with the right number of args on
7261 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
7264 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7266 * app.c: MRI compatibility - allow single quote to start a string.
7267 * as.c: fix typo recently introduced.
7268 * as.h : Don't include aout/reloc.h - it's not right for COFF!
7269 * expr.c: Much rewriting, to accomodate MRI syntax for
7270 expressions. Also easier to read now.
7271 * listing.c: Put back defuns
7272 * read.c: modified to accept MRI syntax, put back listing pseudo
7273 ops so that an assembler built with NO_LISTING ignores list ops
7275 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7276 machine is a SPARC or a 29K.
7277 * config/obj-aout.c: added s_sect pseudo op
7278 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7279 fill in the timestamp.
7280 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7281 anymore, define all the relocs which the tc-<x> bit will use so we
7282 can translate from them to the coff types.
7283 * config/tc-a29k.c: reloc_type isn't ane enum any more
7284 * config/tc-m68k.c: Added NO_RELOC definition.
7286 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
7288 * Makefile.in: put header files before C source for TAGS; remove
7289 references to non-existent syscalls.h.
7291 * read.c, write.c subsegs.c: back out the .bss changes.
7293 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7295 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
7299 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7301 * symbols.c (local_label_name): symbols now start with ^A.
7303 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7304 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7305 generate these sections. .align: will use NOP_OPCODE or 0
7306 for padding. This is just for being nice to the
7309 * expr.c (operand): changed to generate local label "\001L0"
7310 starting with a ^A so that it is recognized as a local label.
7312 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7314 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7315 i/o opcodes - inb, inw, outb and outw. string manipulation with
7316 att syntax - scmp, slod, smov, ssca, ssto.
7318 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7319 to just after .file .
7321 In obj_crawl_symbol_chain() where it tries to put the external
7322 symbols apart, with the condition:
7323 (!S_IS_DEFINED(symbolP) &&
7324 !S_IS_DEBUG(symbolP) &&
7325 !SF_GET_STATICS(symbolP))
7326 it was moving too many symbols out. So I switch it back to the
7328 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7330 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7331 so that we don't use the F_RELFLG which make the linker complain
7332 that somebody has stripped the relocation info.
7334 Also, the AIX ld program require that the relocation table
7335 is sorted by r_vaddr like the standard ATT assembler does.
7337 [he also changed the sizeof(struct ...)'s into the coff
7338 style FOOSZ macros. I'm not sure this is right, but I can't
7339 remember why. xoxorich.]
7341 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
7343 * Makefile.in, configure.in, doc: use the doc. Build it, install
7346 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
7348 * read.c: white space and comments only.
7350 * configure.in: use the new atof-ns32.c for ns32k.
7352 * write.c: comment change only.
7354 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7355 aren't yet integrated.
7357 * tc-i860.[hc]: blew off the dust. Something must still be done
7358 about conflicting relocation types.
7360 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7363 * tc-i960.c, tc-sparc.c: white space and comments only.
7365 * tc-a29k.h: delete duplicate macro definition.
7367 * new file atof-ns32k.c copied from hack's last unreleased gas.
7369 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7371 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7374 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7375 ChangeLog's prior to this are sketchy at best. I have logs.
7376 They just aren't ChangeLogs.
7383 version-control: never
