3685 expression-valued symbol, and calling fix_new_exp recursively.
3686 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
3687 undefined symbol and a constant, fold the constant into the fixup,
3688 and refer to the undefined symbol directly. Then process the
3689 fixup again from scratch.

3726 always use vfprintf, because libiberty will provide it if the
3727 native system doesn't. Also, always make format be const.
3728 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

3744 deciding whether to record it.
3745 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
3746 false (if defined) as well as checking for reg_section.
3747 (listing_listing): Iterate fetching lines while line number is too
3748 low, and we haven't run off the end of the input file.
3750 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
3752 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
3754 * ecoff.c (ecoff_generate_asm_lineno): check if
3755 current_stabs_filename is NULL before strcmp.
3756 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
3759 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3761 * config/ho-*.h: Now-unused files deleted.
3763 * symbols.c (copy_symbol_attributes): New function. Copies BFD
3764 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
3765 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
3766 zero. Don't call obj_frob_forward_symbol.
3767 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
3768 X_add_number is zero.
3769 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
3771 * config/tc-i960.c: Lots of whitespace, comment reformatting,
3773 (strchr): Don't declare.

3775 md_estimate_size_before_relax, md_ri_to_chars,
3776 md_create_short_jump, md_create_long_jump.
3777 (brtab_emit): Use data_section, not SEG_DATA.
3779 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3781 * config/vms-conf.h: new file, manually derived from conf.in.
3782 * config-gas.com: use it, and eliminate obsolete "host.h".

3786 * config/tc-ppc.c (ppc_current_block): New static variable.
3787 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to

3791 (ppc_es): Clear ppc_current_block.
3792 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
3793 from the csect of the enclosing block.
3795 * config/tc-mips.c (insns_since_cache_access): Remove.
3796 (append_insn): Remove setting of insns_since_cache_access, and
3797 special 4600 handling; it turns out not to be required.
3799 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3801 * config/tc-mips.c (md_shortopts): Remove E.
3802 (md_longopts): Add EB and EL.
3803 (md_parse_option): Handle -EB and -EL as separate options, rather
3804 than as a single -E option with an argument.

3808 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
3809 involving global symbols too.
3811 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3813 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
3815 * configure.in: Test for remove, not delete. Fix cross-assembler
3817 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
3820 * read.c (pseudo_set, case O_symbol): If
3821 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
3822 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
3823 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
3825 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
3827 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
3828 many others): new macros; values obtained from "DSTRECRDS.SDL".
3829 * config/obj-vms.h (various): use them.
3830 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
3831 representation (only enum bitfields can avoid being bitstrings).
3832 (bitfield_suffix, setup_basic_type): new routines.
3833 (VMS_typedef_parse): use them. Now recognize bitfields of all
3834 integral types, not just type `int'. Caveat: the representation
3835 used for bitfields still does not work for objects placed in
3836 registers, and gcc's optimizer sometimes puts small structs there.
3838 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3840 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
3841 bit from const_flag.
3842 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
3843 (tc_frob_label): define this to call vms_check_for_special_label,
3844 and declare the latter.
3845 * config/obj-vms.c (vax_g_doubles): declare this file-scope
3847 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
3848 (vms_check_for_special_label): new routine (tc_frob_label).
3849 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
3850 and `gcc2_compiled.' labels; they won't reach here any more.
3851 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
3852 double', use `vax_g_doubles' flag to select type of double.
3853 (VMS_write_object_file) [traceback setup]: don't pass symbols
3854 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
3855 and TBT_Routine_End functions.

3859 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
3860 S_GET_VALUE() to avoid many repeated function calls.
3861 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
3862 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
3863 gets requested. [All the HACK_DEC_C_STARTUP code appears to
3864 be obsolete; gcc does it automatically for vms target. It's
3865 also misnamed, because it is for the "VAX C" run-time library,
3866 not the newer "DEC C" one which has much different startup code.]
3867 {various}: use `S_SET_xxx(symbol,new_value)' rather than
3868 `S_GET_xxx(symbol) = new_value'.
3870 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3872 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
3873 not &bfd_abs_section.
3875 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3877 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
3879 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
3881 * expr.c (expr): Don't reduce the difference of two symbols in the
3882 same frag if the symbols are not in normal sections.
3884 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
3885 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
3886 (obj_attach_unwind_info): Do not define. Not needed anymore.

3888 (struct hppa_fix_struct): Delete fx_unwind field and all references.
3889 (fix_new_hppa): Last arg is now a pointer to an int. Do not
3890 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
3891 fixups, store 32bits of unwind information in the fx_addnumber
3893 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
3894 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
3895 pointer to 32 bits of unwind info.
3896 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
3897 pointer to the dummy symbol; set the addend field to fx_addnumber.
3898 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
3899 rather than &bfd_XXX_section.
3901 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3903 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
3904 value by one; discard adjustments previously being made. From
3907 VMS- and Vax-related changes from Pat Rankin:
3908 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
3909 * vmsconf.sh: no longer have make-gas.com echo text about needing
3910 to modify the gcc-vms driver when intending to use with gcc 1.x.
3911 * as.c (parse_options): suppress 'v' from std_short_options and
3912 eliminate VMS-specific conditional initialization;
3913 [default case]: check for '-v' if md_parse_options doesn't recognize
3915 [default case, #if VMS]: check for filename argument when '-v' seen;
3917 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
3918 for O_big literal operands (double floats and long long ints);
3919 [VMS, md_shortopts]: add second colon after 'v';
3920 (md_parse_options) [VMS, case 'v']: check for argument, so
3921 caller can handle `-v' w/o arg.

3978 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
3979 to ensure that older versions of autoconf aren't used.
3980 * Makefile.in: Added @configure_input@ line.
3981 (configure): Deleted rule.

4066 * ecoff.c (ecoff_build_symbols): If BSF_FUNCTION is set for an
4067 external symbol with no type, set the type to st_Proc rather than

4116 Update for autoconf beta 1.112:
4117 * aclocal.m4 (GAS_CHECK_DECL_NEEDED, GAS_WORKING_ASSERT): New
4119 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
4120 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
4121 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
4122 message to try to ease confusion about autoconf's
4123 "cross-compiling" message.
4124 * acconfig.h (NEED_DECLARATION_MALLOC, NEED_DECLARATION_FREE,
4125 NEED_DECLARATION_ERRNO): Renamed from NEED_*_DECLARATION.

4972 (control_regs): New pointer.
4973 (m68k_ip): Use control_regs instead of testing CPU every time.

5565 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
5566 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
5568 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
5569 branch with an instruction that uses $at, in case the branch is
5571 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
5572 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
5573 to make it pcrel_offset.
5574 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
5575 reloc->address; another gruesome hack to get gas reloc handling to
5578 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5580 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
5583 (emit_insn): New function.
5584 (md_assemble): Call it.
5585 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
5587 (lituse_pending): New variable. Set by anything that generates a
5588 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
5589 tested by code that might want to emit a LITUSE reloc.
5590 (emit_unaligned_io): New function. Currently calls md_assemble,
5591 but it should eventually be converted to generate the insn itself
5592 and call emit_insn directly.
5593 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
5594 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
5595 emit_bis_r): Likewise.

5599 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
5600 unaligned memory access macros.
5601 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
5602 the value can't be resolved.
5604 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5606 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
5607 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
5608 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
5610 (mips_force_relocation): New function.
5611 (md_apply_fix): Set fixP->fx_done appropriately.
5612 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

5620 * config/tc-mips.c (enum mips_pic_level): New enum.
5621 (mips_pic): Change from int to enum mips_pic_level. Change all
5622 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
5623 (load_address): Handle EMBEDDED_PIC.
5624 (macro): Handle EMBEDDED_PIC in all PIC cases.
5625 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
5626 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
5627 -non_shared to use NO_PIC (this is how the Irix 5 assembler
5628 works). Do not permit -G with SVR4_PIC.
5629 (s_abicalls): Warn if -G was used, and force -G 0.
5630 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
5631 anything but a.out, not just for ELF. For ECOFF, don't generate a
5632 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
5634 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
5636 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5638 * config/tc-hppa.c (create_new_space): Use ints, not chars as
5639 parameters to avoid losing when compiling with HP CC.
5640 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
5642 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5644 * Makefile.in (config-stamp): If `defs' is defined, emit a
5645 preprocessor directive to create a macro named by this value into
5646 config.new; don't explicitly go for BFD_ASSEMBLER.
5647 * configure.in: Define `defs', not `BFDDEF'. Set it to
5648 MANY_SEGMENTS for any obj-coffbfd target.
5649 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
5650 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
5652 (LOCAL_LOADLIBES): Deleted.
5653 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
5654 * config/m88kcoff.mt (TDEFINES): Ditto.

5680 bfd_set_symtab is called.
5681 (dump_section_relocs): Note whether a symbol is a section symbol
5683 (adjust_reloc_syms): For now, always supply an absolute symbol for
5684 fixups without symbols but not yet `done'. Use section_symbol to
5685 get the symbol, instead of going directly for abs_symbol.
5686 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
5687 reloc is not a section symbol and is not in the symbol table.
5688 (set_symtab): New function, broken out from write_object_file.
5689 Counts symbol table instead of relying on an earlier count.
5690 (write_object_file): Call set_symtab, but do it after potentially
5691 invoking the *_frob_file macros. Don't bother counting symbols.
5692 Call symbol_remove, instead of expanding it in place. Moved the
5693 conditionalized `object_file_size' declaration down to
5694 conditionalized block where it's used. When using the absolute
5695 symbol for a fixup without a symbol, set sy_used_in_reloc.
5696 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
5697 the correct symbol for the absolute section.
5699 * subsegs.c (section_symbol): Use symbol_new instead of
5700 symbol_make, since we may want it to go into the symbol table.
5701 Make the new symbol have internal linkage. If
5702 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
5703 symbol with the newly created GAS symbol.
5704 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
5705 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

5710 (in_signed_range): New function.
5712 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
5713 (sparc_ip, label "immediate"): Reject constants for pcrel
5714 instructions only if the relocation type indicates a "call"
5715 instruction and the offset is within range of a "jmpl %g0". If
5716 it's not in range, use the absolute section symbol plus an offset.
5717 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
5719 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
5721 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
5724 * configure.in: Eliminated all targets using obj-coff but not
5725 defining BFD_ASSEMBLER; I think all such targets that are
5726 supported will be matched by real CPU-OS combinations earlier in
5728 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
5729 some comments about the dpx2 configuration, but left it disabled,
5730 since it couldn't be reached before.
5731 (target a29k-amd-ebmonold): Deleted.
5733 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

5741 the 'j' operand if there are no further alternatives for this
5744 * config/obj-coffbfd.c (adjust_stab_section): Initialize
5745 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
5746 is not SEG_UNKNOWN rather than checking whether it is >= 0.
5748 * config/tc-mips.c (mips_align): Take new argument, label, and use
5749 it instead of global insn_label.
5750 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
5751 call to mips_emit_delay and pass it to mips_align.
5753 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5755 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
5757 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
5758 argument to a .callinfo directive. Don't loop forever on errors.

5766 S_IS_EXTERNAL when deciding whether to discard a symbol.
5768 * config-gas.com: Scan Makefile.in, not version.c, for current
5769 version number. Delete all versions of temp files when finished
5770 with them. Create config.h.
5772 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
5773 values to reduce number of lookups with S_GET_VALUE. Skip debug
5774 symbols to avoid "a really nasty bug". (From Holger Teutsch,
5775 holger@botbso.rhein-main.de.)
5776 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
5777 field. (Also from Holger Teutsch.) Watch for a would-be register
5778 mask that spans frags.
5780 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
5781 this_base, not line_base. (Patch from Andreas Arens,

5784 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
5785 look local if they're exported or undefined. Used to be done for
5788 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
5789 Get it from the looked-up symbol, instead of using the string from
5790 the input stream, which is no longer null-terminated.
5791 (LEX_PCT): New macro, defaults to 0.
5792 (lex_type): Use it for `%'.
5794 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

5844 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
5845 0xffff for 'j' to be compatible with MIPS assembler. These

7913 OPTIONAL_REGISTER_PREFIX if either is already defined.
7915 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
7917 * configure.in: Set bfd_gas for all sparc targets. Added facility
7918 for keeping or rejecting configurations still under development;
7919 default is to assume production environment, and reject configs
7920 still being worked on. Mark Elf configurations (except sparc and
7921 i386) as developmental. Deleted cases matching some generic names
7922 in favor of more specific names. (E.g., when we get Alpha

7939 through inclusion of tc-hppa.h. Delete all forward declarations
7940 for functions only used within tc-hppa.c, likewise for structures,
7941 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
7942 conditional code in a few small places.
7944 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
7945 structures, global variables, forward declarations together.

7947 conditional code -- try to group conditional code together
7948 into a few places. Make all functions and variables which
7949 are only used within tc-hppa.c static. PARAMize all functions.
7950 Add comments to functions. Delete unused functions, variables,
7951 #defines, etc. Delete unused members within structures. Delete
7952 ldil;ble hacks -- it is believed they were installed to work
7953 around old gas bugs. Avoid using mixed case for local
7954 functions, variables, and structures. Fix formatting problems
7955 not found by GNU-indent. Add FIXME notices for things which
7956 should be worked on the near future. Delete lots of old
7957 useless (1.36 PA-SOM) code.

7974 * config/tc-hppa.c: Likewise.
7976 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
7977 of elf32_symbol_type.
7978 (pa_export_args): Likewise.
7979 (elf_hppa_final_processing): Likewise.

7986 a multiple of the section alignment rather than always a
7989 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
7990 bits are zero (eg they specify no relocations), then do not even
7991 bother adding their entries to thesymextn section.

8036 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
8038 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
8039 ELF, since the ELF object format does not have these type of
8040 relocations. Change the abort into as as_bad and return
8041 BFD_RELOC_NONE to silence compiler warnings.
8042 (md_assemble): Keep track of the instruction size. Allow white

10425 dependencies are read, not when they are used).
10427 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
10428 a29k .bss section; the mondfe program doesn't like it.

10449 source directory, if that's not the current directory.
10451 * configure.in (per-host): Accept MIPS host with BSD version
10453 (per-target): Classify i486 as i386. Use generic cpu_type instead

10477 avoid some redefinition complaints on some systems.
10478 (const, volatile): Don't need these conditionally defined if we
10479 use CONST and VOLATILE from ansidecl.h.
10480 (seg_name): Use CONST, not const.
10482 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
10484 * config/tc-mips.c: Reindented to GNU standards.

10488 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
10489 (fixup_segment): Add a29k special case; the linker is not prepared
10490 to see a segment offset here.

10493 9 to only keep a space in between identifier characters.
10495 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)

10528 dropping a space immediately following an identifier.

10542 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
10543 by the section vma.
10545 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is

10606 prototypes for all static functions. Moved existing minimal
10607 debugging format support info #ifndef OBJ_ECOFF blocks.

10656 * make-gas.com: Find obstack.obj if it's not in the current
10658 * read.c (s_ignore): Don't declare is_end_of_line. It's
10659 redundant, and triggers a VMS gcc compiler bug.
10661 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
10662 current segment as an argument. (Ignored in all cases but VMS.)
10663 All callers and definitions changed.
10665 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
10667 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING
10668 case compile again.
10670 Tue Mar 2 08:53:34 1993 Ken Raeburn (raeburn@cygnus.com)
10672 * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,
10673 so "~0x80" won't be rejected.
10675 * config/obj-elf.c: No longer include elf/reloc.h.
10676 (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
10677 (obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out
10679 (obj_elf_xstab): New routine.
10680 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
10681 argument to s_ignore. Put "#if 0" around unused code.
10682 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
10683 Call elf_xstabs for .stabs and .xstabs operators.
10685 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
10687 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
10690 * configure.in: mips-bsd configuration was missing format spec.
10693 * Makefile.in (Makefile): Depends on configure.in.
10695 * config/tc-mips.c (append_insn): Don't check for alignment of
10696 frag in memory; alignment of instructions in section is a separate
10699 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
10702 * listing.h: Always provide function declarations, not macros, so
10705 Tue Mar 2 00:50:43 1993 John Gilmore (gnu@cygnus.com)

10712 instructions. Accept integer prefetch function numbers.
10714 Wed Feb 24 14:58:19 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
10716 * config/tc-sparc.c (s_xword): Now call big_cons, so large
10717 constants are accepted, but symbolic values are not. GCC will not
10718 generate the latter currently.
10720 * frags.c (frag_init): New function.
10721 (zero_address_frag, bss_address_frag): Now initialized at run
10723 * as.c (main): Call frag_init.

10766 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
10767 (fixup_segment): Make sure common-section symbols get treated the
10768 same as undefined symbols.

10774 * tc.h (md_operand, md_convert_frag, tc_headers_hook,
10775 md_section_align, md_undefined_symbol): Don't provide prototypes
10776 if these are defined as macros.
10777 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and

10799 new section/subsection.
10801 * read.c: Don't include ctype.h.
10802 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
10803 for now; should be machine-dependent.
10805 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format

10997 For now, only accept "no", until the merge is done.
10999 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
11000 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
11001 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
11002 * read.c: Finish conversion to S_* macros in the VMS only
11003 parts of the program. Add "const" modifier to hex_value.

11006 * expr.c: Add "const" modifier to hex_value.
11007 * symbols.c: Finish conversion to S_* macros in the VMS only
11008 parts of the program. Add "const" modifier to
11009 md_[long,short]_jump_size. Remove declaration of const_flag
11010 (which will be declared in obj-vms.h).
11011 * write.c: Add "const" modifier to md_[long,short]_jump_size.
11012 Fix arguments to VMS_write_object_file.
11013 * config-gas.com: New file. Script for VMS systems to set up the
11014 configuration to build gas for VMS, and create config.status.
11015 * make-gas.com: Redone to work with new scheme.
11016 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
11018 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

11022 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
11023 types of malformed stabs. Change parsing algorithm so that we are
11024 more certain of having all of the information that we need on hand.
11025 * obj-vms.c (final_forward_reference): New function, used to help
11026 resolve the data types of as many struct elements as possible

11033 g++ compiler is incapable of doing this.
11034 * tc-vax.c: Add '1' option for backward compatibility with older GCC
11036 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

11044 SEG_DATA or SEG_E1 if needed.
11045 (s_lcomm): Likewise with bss_section.
11046 (s_fill): Use memset, not bzero.

11072 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
11073 mapping to segT enum values.
11074 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
11075 if these are used or defined, if BFD_ASSEMBLER.
11076 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
11077 subseg_new split into two functions.
11078 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.

11100 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
11101 * config/te-sco386.h (LOCAL_LABEL): Don't define.
11102 (DOT_LABEL_PREFIX): Define.
11103 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
11104 name rather than L0\001.
11105 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
11107 * symbols.c, symbols.h (local_bss_counter): Removed.
11108 * write.c (write_object_file): bss no longer uses
11109 local_bss_counter. Pass correct data and bss size to
11110 VMS_write_object_file.
11111 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
11112 argument, rather than using local_bss_counter.

11116 (size_section): Restored sanity check.
11117 (do_relocs_for): Base section address on s_paddr rather than
11118 computing it. Adjust a29k R_IHIHALF special case to account for
11119 section paddr (used to require paddr to be zero). If there are no
11120 reclos, set s_relptr to 0. Set relocation size in object_headers.
11121 (fill_section): Always set s_vaddr here, removing
11122 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
11123 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
11124 Set STYP_INFO for .comment.
11125 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
11126 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

11128 H_{SET,GET}_* macros.
11129 (do_linenos_for): Set lineno size in object_headers.
11130 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
11131 set s_vaddr here. If string_byte_count remains 4, set it back to
11132 0, and only write strings out if there are some. Call
11133 fill_section before do_relocs_for and do_linenos_for.
11134 (obj_coff_section): Handle optional quoted second argument giving
11135 section characteristics.
11136 (obj_coff_bss): Added to handle .bss.
11137 (obj_coff_ident): Added to handle .ident (puts string in .comment

11140 (fixup_mdeps): Change to segment. Call frag_wane after
11142 (fixup_segment): Explicitly check S_IS_COMMON before making 386
11143 adjustment (already happened only for common symbols, but this is
11145 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
11146 * config/tc-i386.c (s_bss): Don't use if I386COFF.

11151 (LOCAL_LABEL): Removed definition.
11152 (DOT_LABEL_PREFIX): Defined.
11154 Mon Dec 28 10:32:05 1992 Ken Raeburn (raeburn@cygnus.com)
11156 * app.c (app_push): Use memcpy, not bcopy.
11157 (do_scrub_next_char): For \", return " not '.
11158 (symbol_chars): Now const.
11160 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
11161 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
11163 * config/obj-coff.h: Don't use #elif.
11165 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
11166 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
11168 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
11170 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

11184 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
11186 * listing.c: Call xmalloc, not malloc; don't declare malloc.
11188 * Changes to support SCO 3.2v4:
11189 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
11190 SEG_BSS, fill with NOP_OPCODE.
11191 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
11192 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
11193 using ZERO_BASED_SEGMENTS.
11194 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
11195 never set segment address for SEG_E2 (.bss) and don't write out
11196 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
11197 (obj_coff_endef): Don't merge labels or symbols awaiting forward
11198 definitions, and don't merge tags with non-tags. Check for .bf
11199 rather than just checking whether the second character is b and
11200 the third character is f.
11201 (obj_coff_val): gcc can generate values which we don't handle
11202 correctly; discard information for now, since it only affects the
11203 debugging information.
11204 (tag_find_or_name): Don't insert tags in the symbol table.
11205 (yank_symbols): Don't merge labels.
11206 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

11208 set segment address if ZERO_BASED_SEGMENTS.
11209 (obj_coff_section): Accept and ignore a trailing quoted string, as
11210 used in AT&T i386 syntax.

11356 z8000 documentation
11357 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
11360 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
11362 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
11364 * subsegs.h: add extern to segment_info declaration.
11366 * read.h: added extern declarations for comment_chars,
11367 line_comment_chars, and line_separator_chars.
11368 read.c, app.c: removed definitions of comment_chars,
11369 line_comment_chars, and line_separator_chars.
11371 * tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
11372 still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
11374 (insert_reg): put REGISTER_PREFIX before register names before

11388 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
11389 constant will not fit in an immediate field.
11390 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

11394 * obj-coff.c (callj_table): Delete global variable.
11395 (obj_emit_relocations): Define it locally here, and only if
11396 TC_I960 is defined.
11398 * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.

11428 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
11429 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
11430 be used to set them all to zero as was done before.
11431 (fill_section): segment addresses now set in write_object_file.
11432 (fill_section): Don't set STYP_NOLOAD for .bss section.
11433 (fixup_segment): 386 uses strange common symbol format.
11434 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for

11455 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
11457 * configure.in: recognize i386-*-bsd emulation.
11459 Thu Oct 1 23:05:12 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
11461 * configure.in: use the cpu-vendor-os triple for host and target
11463 Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com)

11466 * tc-z8k.c: lots of bug fixes
11468 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
11470 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
11471 #elif, since it is not supported by old compilers.
11472 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
11473 couple of expressions in tc-m68k.c.
11475 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11477 * read.c (cons): If NO_RELOC is defined, use it.
11479 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
11481 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
11483 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
11484 local labels to start with a .) and set REGISTER_PREFIX to %.
11485 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
11487 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
11489 * messages.c: Comment changes.
11491 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
11493 * as.h: Test if __STDC__ is defined only, don't test its value.
11494 * messages.c: If __STDC__ is not defined, define NO_STDARG.
11496 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
11498 * listing.c (debugging_pseudo): Add stabs and stabn as things to
11501 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
11503 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
11504 sections starting from zero, rather than making them consecutive.
11505 This makes subsequent reloc calculations easier, esp if the object
11506 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
11507 allocate lcomm in .data rather than in .bss. It seems that some
11508 tools can't cope with a non-zero sized bss before linkage.
11510 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11512 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
11513 throughout. That enum no longer means what we thought it meant.
11515 * tc-m68k.c (md_assemble, md_parse_option): Handle new
11516 "-mno-688[58]1" options.
11518 * tc-m68k.c: Added CPU32 support.
11520 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11522 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.

11526 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
11527 Change LIBDEPS dependence to LIBS.
11529 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
11531 * Makefile.in (install): if $(tooldir) exists, install as in
11534 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
11536 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
11537 .word is < -32768 or > 32767. The -J flag causes the error to be
11538 ignored. This is to catch over-sized switches generated by gcc on
11539 systems which don't support the broken .word hack.
11540 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
11541 write.c (fixup_segment): check for signed .word overflow if
11542 WARN_SIGNED_OVERFLOW_WORD.
11544 * write.c (fixup_segment): fixed missing parens in expression
11545 checking for byte or word overflow.
11547 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

11549 WARN_SIGNED_OVERFLOW_WORD.
11551 * obj-coffbfd.c (fixup_segment): fixed missing parens in
11552 expression checking for byte or word overflow.
11554 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11556 Support for i386 coff
11557 * obj-coffbfd.h : added stuff
11558 * tc-i386.c (tc_coff_fix2rtype): new function
11559 * tc-i386.h : new coff defines

11658 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
11659 written with indirection on the last two operands, which can be
11660 either data or address registers. Added a new operand type 'r'
11661 which accepts either register type. Added '(' to notend stuff in
11662 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

12003 * expr.c: If an expression is single comma, then return with

12024 * listing.c: Put back defuns
12025 * read.c: modified to accept MRI syntax, put back listing pseudo
12026 ops so that an assembler built with NO_LISTING ignores list ops
12028 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
12029 machine is a SPARC or a 29K.
12030 * config/obj-aout.c: added s_sect pseudo op
12031 * config/obj-coffbfd.c: lints, set the filehdr flags right and
12032 fill in the timestamp.
12033 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
12034 anymore, define all the relocs which the tc-<x> bit will use so we
12035 can translate from them to the coff types.
12036 * config/tc-a29k.c: reloc_type isn't ane enum any more
12037 * config/tc-m68k.c: Added NO_RELOC definition.
12039 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
12041 * Makefile.in: put header files before C source for TAGS; remove
12042 references to non-existent syscalls.h.
12044 * read.c, write.c subsegs.c: back out the .bss changes.
12046 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
12048 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
12050 * a.out.h: removed.
12052 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
12054 * symbols.c (local_label_name): symbols now start with ^A.
12056 * read.c, subsegs.c, write.c obj-coff.c: added handling of
12057 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
12058 generate these sections. .align: will use NOP_OPCODE or 0
12059 for padding. This is just for being nice to the
12062 * expr.c (operand): changed to generate local label "\001L0"
12063 starting with a ^A so that it is recognized as a local label.
12065 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
12067 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
12068 i/o opcodes - inb, inw, outb and outw. string manipulation with
12069 att syntax - scmp, slod, smov, ssca, ssto.
12071 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
12072 to just after .file .
12074 In obj_crawl_symbol_chain() where it tries to put the external
12075 symbols apart, with the condition:
12076 (!S_IS_DEFINED(symbolP) &&
12077 !S_IS_DEBUG(symbolP) &&
12078 !SF_GET_STATICS(symbolP))
12079 it was moving too many symbols out. So I switch it back to the
12081 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
12083 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
12084 so that we don't use the F_RELFLG which make the linker complain
12085 that somebody has stripped the relocation info.
12087 Also, the AIX ld program require that the relocation table
12088 is sorted by r_vaddr like the standard ATT assembler does.
12090 [he also changed the sizeof(struct ...)'s into the coff
12091 style FOOSZ macros. I'm not sure this is right, but I can't
12092 remember why. xoxorich.]
12094 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
12096 * Makefile.in, configure.in, doc: use the doc. Build it, install
12099 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
12101 * read.c: white space and comments only.
12103 * configure.in: use the new atof-ns32.c for ns32k.
12105 * write.c: comment change only.
12107 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
12108 aren't yet integrated.
12110 * tc-i860.[hc]: blew off the dust. Something must still be done
12111 about conflicting relocation types.
12113 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
12116 * tc-i960.c, tc-sparc.c: white space and comments only.
12118 * tc-a29k.h: delete duplicate macro definition.
12120 * new file atof-ns32k.c copied from hack's last unreleased gas.
12122 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
12124 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
12127 * nearly everything. flush ChangeLog, package as gas-1.92.1.
12128 ChangeLog's prior to this are sketchy at best. I have logs.
12129 They just aren't ChangeLogs.
