3703 (md_begin): Don't mips_cpu if it was already set.
3704 (md_parse_option): For -mipsN, don't set mips_cpu if it was
3705 already set. For -mcpu=, just set mips_cpu, not mips_isa.

3709 * config/tc-mips.c (md_pseudo_table): If OBJ_ELF, handle .section.
3710 (s_elf_section): New static function.
3711 * ecoff.c (ecoff_build_symbols): Don't abort if we don't recognize

3716 * config/tc-hppa.c (md_apply_fix): Set new_val to 8 for all
3717 fixups to branch instructions (not just pc-relative ones) which

3747 * config/tc-hppa.c: Eliminate all uses of fx_addnumber.
3748 (tc_gen_reloc): Simplify. It's no longer necessary to set a
3749 reloc's addend field to zero for function symbols.
3750 (md_apply_fix): Simplify. For fixups which will require a SOM
3751 reloc, just clear out the necessary bits in the output file.

3755 * Makefile.in (BISON): Use bison -y, not bison.

3769 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
3771 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
3772 it's better to use the one in libiberty.
3774 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3776 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
3777 change; it breaks the rs6000 support, and doesn't seem to be
3780 Wed Oct 12 11:56:50 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
3782 * config/tc-i386.h,te-netbsd532.h (TARGET_FORMAT): Changed to

3788 rather than explicitly adding the frag address.
3789 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark

3791 used to be added by coff_add_linesym, removed Oct 7.
3792 (coff_adjust_section_syms): Ignore sections with no seginfo.
3794 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3796 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a
3797 "stage" symlink to the appropriate stage* directory, and use it
3798 instead in the -B options.
3799 (comparison): Revert yesterday's change.
3801 Tue Oct 11 16:48:11 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

3806 Tue Oct 11 15:24:00 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
3808 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
3809 for an embedded PIC switch expression, since the definition of
3810 S_IS_LOCAL was changed.
3812 Tue Oct 11 15:05:11 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
3814 * Makefile.in (comparison): When comparing as.new or gasp.new, try
3815 running the binary through sed to avoid differences due to
3816 "stage1" or "stage2" having been written into the binary.
3818 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
3820 ELF symbol size handling, based on code from Eric Youngdale:
3821 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an
3822 expression pointer to the symbol structure, used for `size'
3823 expressions that couldn't be reduced to constants when initially
3825 (elf_frob_symbol): Declare.

3828 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
3830 (obj_elf_size): Deleted unused code. If size is non-reducible
3831 expression, allocate some storage for the sy_obj field and copy
3833 (elf_frob_symbol): New function. Computes sizes, calls
3834 ecoff_frob_symbol if appropriate.
3836 * write.c (fixup_segment): For i386 elf and coff (for now), don't
3837 add in value of symbol from another defined section of the file.

3883 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
3885 (diststuff): New target; builds DISTSTUFF.
3886 (realclean): Separate target, depend on clean and distclean, then
3888 * make-gas.com: Deleted.

3896 Add a space after "pc-relative" in the error message.
3897 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
3898 BFD_RELOC_386_GOTOFF relocs.

3902 (TC_VALIDATE_FIX): New macro -- call it.
3903 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.

3908 * write.h (struct fix): Added new bitfield fx_plt, for fixups
3909 referring to PLT entries.
3910 * write.c (fix_new_internal): Initialize fx_plt to zero.
3911 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
3912 Don't adjust fx_offset by frag address, since S_GET_VALUE now
3913 includes the frag address.
3914 (fixup_segment): Changed local var PCREL to type int, added PLT.
3915 If PC-relative fixup refers to a PLT entry for a symbol in the
3916 current section, don't reduce it.

3922 and after processing.
3923 (print_fixup): Added prototype. Show address on first line. Show
3924 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if

3938 Show fx_r_type and fx_addsy fields.
3940 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3942 * configure.in: Set bfd_gas for all sparc targets in one place,
3943 instead of separately for each. Correctly handle user-supplied
3944 "--enable-bfd-gas" option.
3946 * gdbinit.in: Move "break abort" to end, in case gdb complains.
3948 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
3951 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
3952 processing if add_symbol is undefined or in expr_section.
3953 (resolve_symbol_value, case O_add): For symbol plus
3954 constant-valued symbol, convert to O_symbol and re-reduce.
3955 (S_GET_VALUE): If symbol needs resolving, resolve it.
3956 (indent_level): No longer static.
3957 (print_symbol_value_1): Don't print frag address if it matches

3961 (print_expr_1): Fix whitespace before printing X_add_number.
3963 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
3964 not symbol_new, for symbols holding expression values.
3965 * expr.h (make_expr_symbol): Move declaration here.
3966 * write.c (fix_new_exp): Handle O_add by creating an
3967 expression-valued symbol, and calling fix_new_exp recursively.
3968 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
3969 undefined symbol and a constant, fold the constant into the fixup,
3970 and refer to the undefined symbol directly. Then process the
3971 fixup again from scratch.
3972 (write_object_file): Before calling adjust_reloc_syms, make a pass
3973 through the symbol list trying to resolve values.
3975 * write.c (print_fixup): New routine, for debugging.
3976 (write_relocs): Call bfd_install_relocation. Deleted various
3977 hacks for working around problems with bfd_perform_relocation.
3979 * Makefile.in (VERSION): Update to 2.4.90.
3981 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3983 * Makefile.in (gasp.o): Depends upon config.h.
3985 * config/tc-mips.c: Include subsegs.h.
3986 (md_apply_fix): If an unconditional b or bal overflows, and we are
3987 not assembling PIC code, replace it with a j or jal.
3989 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
3990 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
3992 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3994 * write.c (write_relocs): Add file name and line number to
3995 as_fatal calls. Handle bfd_reloc_overflow case specifically when
3996 RELOC_EXPANSION_POSSIBLE.
3998 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4000 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
4001 here. Use them for deciding which PRINTF*LIKE macro definitions
4003 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
4004 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
4005 default definitions matching what we were doing before.
4006 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
4007 always use the varargs form if not using stdarg. It's safe to
4008 always use vfprintf, because libiberty will provide it if the
4009 native system doesn't. Also, always make format be const.
4010 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
4012 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

4025 (listing_newline): Check filename as well as line number when
4026 deciding whether to record it.
4027 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
4028 false (if defined) as well as checking for reg_section.
4029 (listing_listing): Iterate fetching lines while line number is too
4030 low, and we haven't run off the end of the input file.
4032 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
4034 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
4036 * ecoff.c (ecoff_generate_asm_lineno): check if
4037 current_stabs_filename is NULL before strcmp.
4038 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
4041 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4043 * config/ho-*.h: Now-unused files deleted.
4045 * symbols.c (copy_symbol_attributes): New function. Copies BFD
4046 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
4047 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
4048 zero. Don't call obj_frob_forward_symbol.
4049 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
4050 X_add_number is zero.
4051 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
4053 * config/tc-i960.c: Lots of whitespace, comment reformatting,
4055 (strchr): Don't declare.
4056 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
4057 md_estimate_size_before_relax, md_ri_to_chars,
4058 md_create_short_jump, md_create_long_jump.
4059 (brtab_emit): Use data_section, not SEG_DATA.
4061 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
4063 * config/vms-conf.h: new file, manually derived from conf.in.
4064 * config-gas.com: use it, and eliminate obsolete "host.h".
4066 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4068 * config/tc-ppc.c (ppc_current_block): New static variable.
4069 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
4070 ppc_current_block. Don't move around any stab symbol, just those
4072 (ppc_bs): Set ppc_current_block.
4073 (ppc_es): Clear ppc_current_block.
4074 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
4075 from the csect of the enclosing block.
4077 * config/tc-mips.c (insns_since_cache_access): Remove.
4078 (append_insn): Remove setting of insns_since_cache_access, and
4079 special 4600 handling; it turns out not to be required.
4081 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4083 * config/tc-mips.c (md_shortopts): Remove E.
4084 (md_longopts): Add EB and EL.
4085 (md_parse_option): Handle -EB and -EL as separate options, rather
4086 than as a single -E option with an argument.
4088 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
4090 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
4091 involving global symbols too.
4093 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4095 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
4097 * configure.in: Test for remove, not delete. Fix cross-assembler
4099 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
4102 * read.c (pseudo_set, case O_symbol): If
4103 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
4104 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
4105 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
4107 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
4109 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
4110 many others): new macros; values obtained from "DSTRECRDS.SDL".
4111 * config/obj-vms.h (various): use them.
4112 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
4113 representation (only enum bitfields can avoid being bitstrings).
4114 (bitfield_suffix, setup_basic_type): new routines.
4115 (VMS_typedef_parse): use them. Now recognize bitfields of all
4116 integral types, not just type `int'. Caveat: the representation
4117 used for bitfields still does not work for objects placed in
4118 registers, and gcc's optimizer sometimes puts small structs there.
4120 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
4122 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
4123 bit from const_flag.
4124 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
4125 (tc_frob_label): define this to call vms_check_for_special_label,
4126 and declare the latter.
4127 * config/obj-vms.c (vax_g_doubles): declare this file-scope
4129 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
4130 (vms_check_for_special_label): new routine (tc_frob_label).
4131 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
4132 and `gcc2_compiled.' labels; they won't reach here any more.
4133 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
4134 double', use `vax_g_doubles' flag to select type of double.
4135 (VMS_write_object_file) [traceback setup]: don't pass symbols
4136 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
4137 and TBT_Routine_End functions.
4139 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
4141 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
4142 S_GET_VALUE() to avoid many repeated function calls.
4143 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
4144 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
4145 gets requested. [All the HACK_DEC_C_STARTUP code appears to
4146 be obsolete; gcc does it automatically for vms target. It's
4147 also misnamed, because it is for the "VAX C" run-time library,
4148 not the newer "DEC C" one which has much different startup code.]

5197 * read.c (emit_expr): Use memset to zero out memory, rather than
5198 going through md_number_to_chars. This permits handling symbolic

5251 m68040_control_regs, m68060_control_regs): New arrays.
5252 (control_regs): New pointer.
5253 (m68k_ip): Use control_regs instead of testing CPU every time.
5254 Use last_movec_reg too. In error messages, handle 68060, and
5255 print 68060 for mfloat, too.
5256 (m68k_init_after_args): Handle "68060". Use m68040up for making
5257 m68851 choice. Set control_regs.

5545 * listing.c (list_symbol_table): Print "NO DEFINED SYMBOLS" and
5546 "NO UNDEFINED SYMBOLS" if there aren't any, instead of displaying
5547 the header with an empty list.
5549 * config/obj-coffbfd.c (fill_section): Check COFF_NOLOAD_PROBLEM
5550 also before setting STYP_NOLOAD for .bss section.
5552 * config/tc-m68k.c (flag_reg_prefix_optional): New variable.
5553 Initialized to value of REGISTER_PREFIX_OPTIONAL, if defined, or

5556 register prefix to be absent.
5557 (m68k_ip_op): Accept `&' also for immediate constants.
5558 (insert_reg): Don't bother with (two!?) sanity checks of the
5559 symbol table when inserting each register.

5569 * config/tc-m68k.c (DATA, ADDR, SP, FPREG, COPNUM, BAD, BAC):
5570 Define as macros instead of enumerators, since the Apollo compiler
5571 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum

5574 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
5575 R_DIR16, and R_DIR32 relocs.
5576 * config/tc-m68k.h [TE_APOLLO] (COFF_MAGIC, COFF_AOUTHDR_MAGIC):
5577 Use Apollo versions.
5578 [TE_APOLLO] (OBJ_COFF_OMIT_OPTIONAL_HEADER): Undefine. That is,

5585 * config/tc-m68k.h (m68k_init_after_args): Declare.
5586 (tc_init_after_args): Define as m68k_init_after_args.
5587 * config/tc-m68k.c (m68k_init_after_args): New function,
5588 containing one-shot code from md_assemble. Added warning for

5605 masks, rather than using the now obsolete fake .reginfo section.
5607 Fri Apr 22 15:17:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5609 * listing.c (list_symbol_table): Don't print register symbols as
5612 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
5613 underscores, since symbol_new will already have done it.

5616 * as.c (main): If tc_init_after_args is defined, invoke it after
5617 all arguments have been processed.

5620 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
5621 section instead of .text. Call create_target_segments.
5622 * read.c (demand_copy_string): No longer static.
5624 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5626 * config/tc-mips.c (append_insn): Permit branches to be switched
5627 with the preceding instruction even if .set nobopt has been seen.
5628 .set nobopt actually controls whether to bring up an instruction
5629 from the branch target, which gas does not currently support.
5631 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5633 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

5646 * config/tc-sparc.c (md_section_align): Always round up to
5647 multiple of alignment power specified in bfd target vector.
5649 * gasp.c: Include ctype.h.

5680 (add_procedure): Set first_proc_ptr if it hasn't been set.
5681 (ecoff_build_lineno): If the first procedure does not start at
5682 address zero, insert a dummy line to compensate.
5684 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
5687 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5689 * expr.c (operand): Try to parse "0f" and "0b" sequences as
5690 floating point and binary numbers respectively; if it doesn't
5691 work, treat them as local labels.
5693 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
5694 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
5696 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
5698 * vmsconf.sh: In generated file, get ".obj" suffix right, build
5699 source files from other directories into objects in the current
5700 directory, and specify PSECT attributes explicitly to linker.
5701 Also added missing label.
5702 * Makefile.in (stamp-mk.com): Reference new variable

5720 argument, the reloc type.
5721 (load_register): Pass reloc type to macro_build for 'u'.
5722 (macro): Likewise. For M_LA_AB permit a difference expression
5723 when generating embedded PIC code between an arbitrary symbol and
5724 a symbol in the .text section.
5725 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and

5766 (hppa_tc_symbol): Likewise.
5768 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
5769 elf_tc_make_sections stuff. It was there to support PA braindamage
5770 which has been fixed, and in the case of elf_tc_make_sections is
5771 redundant with elf_tc_final_processing.
5773 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5775 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

5790 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
5791 don't spew remainder of input file in error message.
5792 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
5793 message with reloc type and try to process remainder of file.
5795 * doc/Makefile.in (install-info-as, install-info-gasp): New
5796 targets, now explicitly checking $(srcdir) for info files.
5797 (install-info): Depend on both of them; do nothing more.

5801 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
5803 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5805 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
5806 flag rather than signedp field. Only permit extended range if
5807 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
5808 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
5810 * config/tc-ppc.c (ppc_size): New static variable.
5811 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
5812 (md_begin): If an instruction has a size specific flag set, only
5813 add it if we are assembling that size.
5815 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5817 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
5818 cross section PC relative relocs right for COFF and ELF.
5820 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5822 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
5823 (OBJ_PROCESS_STAB): Don't define.

5827 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
5828 the type of symbol set symbols which happen to be in the absolute
5829 or undefined section.
5831 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
5833 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
5834 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
5835 and -many (all architectures).

5846 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
5848 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
5849 branch with an instruction that uses $at, in case the branch is
5851 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
5852 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
5853 to make it pcrel_offset.
5854 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
5855 reloc->address; another gruesome hack to get gas reloc handling to
5858 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5860 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
5863 (emit_insn): New function.
5864 (md_assemble): Call it.
5865 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
5867 (lituse_pending): New variable. Set by anything that generates a
5868 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
5869 tested by code that might want to emit a LITUSE reloc.
5870 (emit_unaligned_io): New function. Currently calls md_assemble,
5871 but it should eventually be converted to generate the insn itself
5872 and call emit_insn directly.
5873 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
5874 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
5875 emit_bis_r): Likewise.
5876 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
5877 (alpha_ip, label get_macro): Don't emit the final instruction if
5879 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
5880 unaligned memory access macros.
5881 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
5882 the value can't be resolved.
5884 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5886 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
5887 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

5900 * config/tc-mips.c (enum mips_pic_level): New enum.
5901 (mips_pic): Change from int to enum mips_pic_level. Change all
5902 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
5903 (load_address): Handle EMBEDDED_PIC.
5904 (macro): Handle EMBEDDED_PIC in all PIC cases.
5905 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
5906 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
5907 -non_shared to use NO_PIC (this is how the Irix 5 assembler
5908 works). Do not permit -G with SVR4_PIC.
5909 (s_abicalls): Warn if -G was used, and force -G 0.
5910 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
5911 anything but a.out, not just for ELF. For ECOFF, don't generate a
5912 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
5914 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.

5922 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5924 * Makefile.in (config-stamp): If `defs' is defined, emit a
5925 preprocessor directive to create a macro named by this value into
5926 config.new; don't explicitly go for BFD_ASSEMBLER.
5927 * configure.in: Define `defs', not `BFDDEF'. Set it to
5928 MANY_SEGMENTS for any obj-coffbfd target.
5929 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
5930 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
5932 (LOCAL_LOADLIBES): Deleted.
5933 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
5934 * config/m88kcoff.mt (TDEFINES): Ditto.
5935 * config/ebmon29k.mt: Deleted.
5936 * config/h8300hds.mt: Deleted.
5937 * config/ic960coff.mt: Deleted.
5938 * config/sparc.mt: Deleted.
5939 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
5940 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
5941 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
5942 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

5960 bfd_set_symtab is called.
5961 (dump_section_relocs): Note whether a symbol is a section symbol
5963 (adjust_reloc_syms): For now, always supply an absolute symbol for
5964 fixups without symbols but not yet `done'. Use section_symbol to
5965 get the symbol, instead of going directly for abs_symbol.
5966 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
5967 reloc is not a section symbol and is not in the symbol table.
5968 (set_symtab): New function, broken out from write_object_file.
5969 Counts symbol table instead of relying on an earlier count.
5970 (write_object_file): Call set_symtab, but do it after potentially
5971 invoking the *_frob_file macros. Don't bother counting symbols.
5972 Call symbol_remove, instead of expanding it in place. Moved the
5973 conditionalized `object_file_size' declaration down to
5974 conditionalized block where it's used. When using the absolute
5975 symbol for a fixup without a symbol, set sy_used_in_reloc.
5976 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
5977 the correct symbol for the absolute section.
5979 * subsegs.c (section_symbol): Use symbol_new instead of
5980 symbol_make, since we may want it to go into the symbol table.

7859 pass new argument for i, j and o cases.
7860 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

8081 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
8082 the table, require that the one without bit 0x1000000 set come
8083 first. Require further that it be case 'b' or 'P'. The a29k
8084 opcode table already meets these constraints.
8085 (machine_ip): When handling case 'i' or 'A', make sure that the

8141 * write.c (write_relocs): For relocs that are pc_relative and
8142 pcrel_offset and not partial_inplace, adjust reloc->addend to

8193 OPTIONAL_REGISTER_PREFIX if either is already defined.
8195 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
8197 * configure.in: Set bfd_gas for all sparc targets. Added facility
8198 for keeping or rejecting configurations still under development;
8199 default is to assume production environment, and reject configs
8200 still being worked on. Mark Elf configurations (except sparc and
8201 i386) as developmental. Deleted cases matching some generic names
8202 in favor of more specific names. (E.g., when we get Alpha
8203 support, we'll still only support VMS for Vax.)

8219 through inclusion of tc-hppa.h. Delete all forward declarations
8220 for functions only used within tc-hppa.c, likewise for structures,
8221 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
8222 conditional code in a few small places.
8224 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
8225 structures, global variables, forward declarations together.

8227 conditional code -- try to group conditional code together
8228 into a few places. Make all functions and variables which
8229 are only used within tc-hppa.c static. PARAMize all functions.
8230 Add comments to functions. Delete unused functions, variables,
8231 #defines, etc. Delete unused members within structures. Delete
8232 ldil;ble hacks -- it is believed they were installed to work
8233 around old gas bugs. Avoid using mixed case for local
8234 functions, variables, and structures. Fix formatting problems
8235 not found by GNU-indent. Add FIXME notices for things which
8236 should be worked on the near future. Delete lots of old
8237 useless (1.36 PA-SOM) code.
8239 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
8240 field of the fixS structure. Needed to build unwind
8241 descriptors correctly.

8266 a multiple of the section alignment rather than always a
8269 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
8270 bits are zero (eg they specify no relocations), then do not even
8271 bother adding their entries to thesymextn section.

8312 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
8313 call strchr for each character to see if it is a special char,
8314 instead add a second loop over special_chars. Set alignment
8315 of text, data and bss sections to 4.
8316 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
8318 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
8319 ELF, since the ELF object format does not have these type of
8320 relocations. Change the abort into as as_bad and return
8321 BFD_RELOC_NONE to silence compiler warnings.

9334 are also magic, and have special default flag settings.
9335 (obj_elf_frob_symbol): Since the return value from this function

9399 * Extensive changes to permit symbols to contain any expression
9400 type and to delay the computation of the expression until the
9401 value is actually needed. This permits setting symbols to values
9402 calculated based on object code size. Expressions were changed to
9403 no longer be in a section, to stop the overloading of segment and
9404 expression type that previously occurred.
9406 * as.c (big_section, pass1_section, diff_section, absent_section):
9408 (expr_section): Added (used for dummy symbols which hold

9492 (previous_section, previous_subsection): New vars.
9493 (obj_elf_section): Save current place in case DWARF code wants us
9494 to pop back to it. Handle unquoted section name as well as quoted
9495 section name. Don't crash on invalid strings.
9496 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

9605 * Removed sy_forward and replaced it with an undefined expression
9606 as the value of a symbol.

9608 sy_resolved and sy_resolving single bit fields.
9609 * symbols.c (symbol_new): Don't initialize sy_forward field.

9613 * read.c (pseudo_set): Set symbolP->sy_value to an undefined
9614 expression rather than setting symbolP->sy_forward.

10701 Mon Mar 29 12:56:56 1993 Ian Lance Taylor (ian@cygnus.com)
10703 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
10704 the bottom (make expands variables in dependencies when the
10705 dependencies are read, not when they are used).
10707 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
10708 a29k .bss section; the mondfe program doesn't like it.

10723 (srcdir): Delete second, bogus definition.
10724 (as.info): Look for as-*.texinfo in current directory rather than
10728 * doc/configure.in: Create links to all as-*.texinfo files in the
10729 source directory, if that's not the current directory.
10731 * configure.in (per-host): Accept MIPS host with BSD version
10733 (per-target): Classify i486 as i386. Use generic cpu_type instead

10753 process relocs if there aren't any relocs to process. Avoids
10754 malloc/free bug on SCO too.
10756 * as.h: Move local include files below system include files, to
10757 avoid some redefinition complaints on some systems.
10758 (const, volatile): Don't need these conditionally defined if we
10759 use CONST and VOLATILE from ansidecl.h.
10760 (seg_name): Use CONST, not const.
10762 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
10764 * config/tc-mips.c: Reindented to GNU standards.

10768 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

10773 9 to only keep a space in between identifier characters.
10775 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
10777 * Makefile.in: add dvi target; as-$(config).texinfo might live in
10778 srcdir, might be in objdir.
10780 * doc/Makefile.in: dvi depends on as.dvi

10807 * app.c (do_scrub_next_char): Added new state, 9, to avoid
10808 dropping a space immediately following an identifier.
10809 * expr.c, write.c: Rewrote assert expressions to not use multiple
10810 lines; I don't think that can be done portably.
10811 * config/tc-mips.c (macro): Use $AT if target register is zero in
10812 load instruction, which it can be for a floating point load.
10814 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

10819 symbol table and values right.
10820 * config/tc-mips.h (LOCAL_LABEL): If OBJ_ECOFF, any label starting
10822 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
10823 by the section vma.
10825 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
10826 z8k-opc.h, not z8k.h.
10828 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
10831 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

10882 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
10883 (struct loc, struct proc, struct file): Moved to tc-mips.c within

10885 * config/tc-mips.c: Rearranged for ECOFF support. Added
10886 prototypes for all static functions. Moved existing minimal
10887 debugging format support info #ifndef OBJ_ECOFF blocks.
10888 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
10889 does not support a non sign extended high 16 bits reloc. Adjusted

10936 * make-gas.com: Find obstack.obj if it's not in the current
10938 * read.c (s_ignore): Don't declare is_end_of_line. It's
10939 redundant, and triggers a VMS gcc compiler bug.
10941 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
10942 current segment as an argument. (Ignored in all cases but VMS.)
10943 All callers and definitions changed.
10945 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
10947 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING

10967 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
10970 * configure.in: mips-bsd configuration was missing format spec.
10973 * Makefile.in (Makefile): Depends on configure.in.
10975 * config/tc-mips.c (append_insn): Don't check for alignment of

10996 * config/tc-sparc.c (s_xword): Now call big_cons, so large
10997 constants are accepted, but symbolic values are not. GCC will not
10998 generate the latter currently.

11034 Use S_SET_TYPE, S_GET_TYPE, and S_GET_DESC instead of directly
11035 referencing symbol structure members.
11036 (obj_aout_frob_symbol) [BFD_ASSEMBLER]: New function.
11038 * as.h (struct frag): Reordered a couple of fields for better

11046 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
11047 (fixup_segment): Make sure common-section symbols get treated the
11048 same as undefined symbols.
11049 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type

11055 md_section_align, md_undefined_symbol): Don't provide prototypes
11056 if these are defined as macros.
11057 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and

11253 * config/tc-sparc.c (architecture_requested, warn_on_bump,
11254 md_relax_table): Use default zero initialization.
11255 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

11268 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
11270 * expr.c (operand): If character other than comma or newline is a
11271 logical end-of-line character, use the newline case.
11272 From Eric Youngdale:
11273 (operand): Set X_add_number field for floating-point numbers.
11274 (operand): Treat zero byte as end-of-operand.
11276 * configure.in (per-target): Look for with_bfd_assembler option.
11277 For now, only accept "no", until the merge is done.
11279 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
11280 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
11281 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
11282 * read.c: Finish conversion to S_* macros in the VMS only
11283 parts of the program. Add "const" modifier to hex_value.
11284 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
11286 * expr.c: Add "const" modifier to hex_value.
11287 * symbols.c: Finish conversion to S_* macros in the VMS only
11288 parts of the program. Add "const" modifier to
11289 md_[long,short]_jump_size. Remove declaration of const_flag
11290 (which will be declared in obj-vms.h).
11291 * write.c: Add "const" modifier to md_[long,short]_jump_size.
11292 Fix arguments to VMS_write_object_file.
11293 * config-gas.com: New file. Script for VMS systems to set up the
11294 configuration to build gas for VMS, and create config.status.
11295 * make-gas.com: Redone to work with new scheme.
11296 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
11298 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
11299 will swap bytes if needed on a big endian system. Use throughout
11301 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
11302 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
11303 types of malformed stabs. Change parsing algorithm so that we are
11304 more certain of having all of the information that we need on hand.
11305 * obj-vms.c (final_forward_reference): New function, used to help
11306 resolve the data types of as many struct elements as possible
11307 when some part of the struct is not fully defined by the compiler.
11308 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
11310 * obj-vms.c (VMS_write_object_file): Define all vtable psects
11311 as symbols as well in the object file. Look for external functions

11321 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
11323 * read.c (s_data): Always use "data_section", since it'll map to
11324 SEG_DATA or SEG_E1 if needed.
11325 (s_lcomm): Likewise with bss_section.
11326 (s_fill): Use memset, not bzero.
11328 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

11348 (seg_name): Declare only if not BFD_ASSEMBLER.
11349 (section_alignment): Declare only if not BFD_ASSEMBLER.
11350 (big_section, reg_section, pass1_section, diff_section,
11351 absent_section, text_section, data_section, bss_section): If
11352 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
11353 mapping to segT enum values.
11354 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
11355 if these are used or defined, if BFD_ASSEMBLER.
11356 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
11357 subseg_new split into two functions.
11358 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
11360 * as.h (volatile): Don't define if already defined.
11361 (had_errors, had_warnings): Provide prototypes for ANSI C even if

11364 declare with format attribute for -Wformat checking.
11366 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
11368 * app.c, config/tc-*.c: Don't include read.h, since it is already

11372 <mtranle@paris.intellicorp.com>.
11373 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
11374 obj_format coffbfd and gas_target i386coff for target.

11376 * config/i386aix.mt: Removed (no longer used).
11377 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
11378 (MINUS_G): Removed.
11379 (LDFLAGS): Added, defined as -shlib.
11380 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
11381 * config/te-sco386.h (LOCAL_LABEL): Don't define.
11382 (DOT_LABEL_PREFIX): Define.
11383 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label

11387 * symbols.c, symbols.h (local_bss_counter): Removed.
11388 * write.c (write_object_file): bss no longer uses
11389 local_bss_counter. Pass correct data and bss size to
11390 VMS_write_object_file.
11391 * config/obj-vms.c (VMS_write_object_file): Accept bss size as

11396 (size_section): Restored sanity check.
11397 (do_relocs_for): Base section address on s_paddr rather than
11398 computing it. Adjust a29k R_IHIHALF special case to account for
11399 section paddr (used to require paddr to be zero). If there are no
11400 reclos, set s_relptr to 0. Set relocation size in object_headers.
11401 (fill_section): Always set s_vaddr here, removing
11402 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
11403 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
11404 Set STYP_INFO for .comment.
11405 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
11406 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

11408 H_{SET,GET}_* macros.
11409 (do_linenos_for): Set lineno size in object_headers.
11410 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
11411 set s_vaddr here. If string_byte_count remains 4, set it back to
11412 0, and only write strings out if there are some. Call
11413 fill_section before do_relocs_for and do_linenos_for.
11414 (obj_coff_section): Handle optional quoted second argument giving
11415 section characteristics.
11416 (obj_coff_bss): Added to handle .bss.
11417 (obj_coff_ident): Added to handle .ident (puts string in .comment

11437 (do_scrub_next_char): For \", return " not '.
11438 (symbol_chars): Now const.
11440 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
11441 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
11443 * config/obj-coff.h: Don't use #elif.
11445 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
11446 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
11448 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
11450 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

11462 * read.c (read_a_source_file): avoid calling xmalloc (0).
11464 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
11466 * listing.c: Call xmalloc, not malloc; don't declare malloc.
11468 * Changes to support SCO 3.2v4:
11469 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
11470 SEG_BSS, fill with NOP_OPCODE.
11471 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
11472 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
11473 using ZERO_BASED_SEGMENTS.
11474 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
11475 never set segment address for SEG_E2 (.bss) and don't write out
11476 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
11477 (obj_coff_endef): Don't merge labels or symbols awaiting forward
11478 definitions, and don't merge tags with non-tags. Check for .bf
11479 rather than just checking whether the second character is b and
11480 the third character is f.
11481 (obj_coff_val): gcc can generate values which we don't handle
11482 correctly; discard information for now, since it only affects the
11483 debugging information.
11484 (tag_find_or_name): Don't insert tags in the symbol table.
11485 (yank_symbols): Don't merge labels.
11486 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
11487 already defined. Fill subsegments with NOP_OPCODE, not 0. Don't
11488 set segment address if ZERO_BASED_SEGMENTS.
11489 (obj_coff_section): Accept and ignore a trailing quoted string, as
11490 used in AT&T i386 syntax.
11491 (fixup_segment): Take segment as argument. On the i386, adjust PC
11492 relative addends by the segment vaddr.
11493 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
11494 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

11636 z8000 documentation
11637 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
11640 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
11642 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
11644 * subsegs.h: add extern to segment_info declaration.
11646 * read.h: added extern declarations for comment_chars,
11647 line_comment_chars, and line_separator_chars.
11648 read.c, app.c: removed definitions of comment_chars,
11649 line_comment_chars, and line_separator_chars.

11668 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
11669 constant will not fit in an immediate field.

11674 * obj-coff.c (callj_table): Delete global variable.
11675 (obj_emit_relocations): Define it locally here, and only if
11676 TC_I960 is defined.
11678 * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.

11707 * Support for i386-sysv.
11708 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
11709 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
11710 be used to set them all to zero as was done before.
11711 (fill_section): segment addresses now set in write_object_file.
11712 (fill_section): Don't set STYP_NOLOAD for .bss section.
11713 (fixup_segment): 386 uses strange common symbol format.

11748 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
11750 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
11751 #elif, since it is not supported by old compilers.
11752 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
11753 couple of expressions in tc-m68k.c.
11755 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11757 * read.c (cons): If NO_RELOC is defined, use it.

11763 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
11764 local labels to start with a .) and set REGISTER_PREFIX to %.
11765 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
11767 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
11769 * messages.c: Comment changes.
11771 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

11774 * messages.c: If __STDC__ is not defined, define NO_STDARG.
11776 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
11778 * listing.c (debugging_pseudo): Add stabs and stabn as things to
11781 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
11783 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
11784 sections starting from zero, rather than making them consecutive.
11785 This makes subsequent reloc calculations easier, esp if the object
11786 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
11787 allocate lcomm in .data rather than in .bss. It seems that some
11788 tools can't cope with a non-zero sized bss before linkage.
11790 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11792 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
11793 throughout. That enum no longer means what we thought it meant.
11795 * tc-m68k.c (md_assemble, md_parse_option): Handle new
11796 "-mno-688[58]1" options.
11798 * tc-m68k.c: Added CPU32 support.
11800 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11802 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.

11811 * Makefile.in (install): if $(tooldir) exists, install as in
11814 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
11816 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
11817 .word is < -32768 or > 32767. The -J flag causes the error to be
11818 ignored. This is to catch over-sized switches generated by gcc on
11819 systems which don't support the broken .word hack.
11820 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
11821 write.c (fixup_segment): check for signed .word overflow if
11822 WARN_SIGNED_OVERFLOW_WORD.
11824 * write.c (fixup_segment): fixed missing parens in expression
11825 checking for byte or word overflow.
11827 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
11828 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
11829 WARN_SIGNED_OVERFLOW_WORD.
11831 * obj-coffbfd.c (fixup_segment): fixed missing parens in
11832 expression checking for byte or word overflow.

11839 * tc-i386.h : new coff defines
11841 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
11843 * input-scrub.c (input_scrub_push): call input_file_begin, not
11845 messages.c (as_perror): print ": " between the passed in error and
11846 the strerror, like perror does.
11848 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

11855 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
11856 Motorola and MIT syntax; gas can now assemble either type of
11858 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
11859 From Steve Chamberlain:
11860 m68kcoff.mt: for m68k COFF.
11861 obj-coffbfd.c: (fixup_mdeps) added
11862 (size_section) removed bad sanity check
11863 (fill_section) added rs_machine_dependent case
11864 (write_object_file) call fixup_mdeps
11865 (fixup_segment) set fx_subsy to 0.
11866 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
11868 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
11871 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11873 * Makefile.in (LIBS): Include opcode library.

11894 * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
11895 tc-i960.c (md_ri_to_chars): Always output bout object file in
11896 little endian byte order (used to use endianness of host).
11898 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11900 * config/tc-m68k.c (init_table): Now const. Always include 68851
11901 data, so that "bc" is available to 68040 cache instructions.
11902 Added "tt0", "tt1", and 68ec030 variants.
11903 (md_assemble): Complain if 68000 (only) and 68881 are specified.
11904 (enum _register): Added TT0, TT1.
11905 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
11906 line number correctly in "internal error" messages. Don't print
11907 architecture-mismatch message for operand errors.
11909 From Colin Smith (colin@wrs.com):
11910 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
11911 than install_operand.
11913 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11915 * listing.c (buffer_line): rewind to the start of include
11916 files, they might be included twice.
11918 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
11920 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
11922 * Makefile.in: defined TARGET_CPU for C code so that it can choose
11923 one element of a family.
11925 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
11927 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
11928 so that we can assemble hand-written libgcc code.
11930 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11932 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
11933 has already been formatted (but may still contain %-characters).
11934 (as_bad): Likewise.
11936 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
11938 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
11939 written with indirection on the last two operands, which can be
11940 either data or address registers. Added a new operand type 'r'
11941 which accepts either register type. Added '(' to notend stuff in
11942 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
11944 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
11946 * as.h (enum _relax_state): Start off at one, not zero, to better
11947 catch uninitialized-variable errors.
11948 (linkrelax): Declare new variable.
11950 * messages.c (warning_count, error_count): Default initializer is
11953 * write.c: Merged some declarations, using PARMS macro.
11954 (text_frag_root, data_frag_root, bss_frag_root, text_last_frag,
11955 data_last_frag): No longer static.
11956 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
11957 defined, call it. Change segments before calling fixup_segment.
11958 (relax_align): If linkrelax, provide extra padding.
11960 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
11961 their not having symbols associated.
11963 * tc-i960.c (norelax, instrument_branches): Default initializer is
11965 (linkrelax): Delete variable definition.

12049 ancient or broken compilers.
12051 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
12052 processor/opcode mismatch, so reword the error message.
12053 (md_assemble): If no CPU has been set (even if FPU/PMMU
12054 characteristics have been), default to 68020. Don't need extra
12055 quotes around error string.

12193 * Makefile.in (install): Install into $(tooldir)/bin, since that's
12194 where gcc looks for it.
12196 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
12198 * Makefile.in: Changed some lines to be less confusing for some

12228 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
12230 * configure.in: vxworks68 gets te-sun3.h.
12232 * expr.c: remove limitation that local_labels_dollar or
12233 local_labels_fb must be < 10.
12235 * symbols.c: remove local_labels_dollar, replace with a function
12236 interface for a sparse array. All users adjusted.
12238 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
12240 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

12264 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
12266 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
12268 * expr.c (operand): if can't work out what sort of operand it is,
12269 then look through FLT_CHARS for a hint.
12271 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
12273 * Makefile.in, configure.in: removed traces of namesubdir,
12274 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
12275 copyrights to '92, changed some from Cygnus to FSF.
12277 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
12278 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
12279 copyrights to '92, changed some from Cygnus to FSF.
12281 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
12283 * expr.c: If an expression is single comma, then return with
12284 SEG_ABSENT rather than an error - since the sparc front end does
12285 really strange things with things like fbge,a
12287 * as.h: include bfd.h if using many sections
12288 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
12289 local labels didn't work.
12290 * listing.c (list_symbol_table): don't core dump when there's no
12292 * write.c, write.h: call fix_new with the right number of args on
12294 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
12297 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
12299 * app.c: MRI compatibility - allow single quote to start a string.
12300 * as.c: fix typo recently introduced.
12301 * as.h : Don't include aout/reloc.h - it's not right for COFF!
12302 * expr.c: Much rewriting, to accomodate MRI syntax for
12303 expressions. Also easier to read now.
12304 * listing.c: Put back defuns
12305 * read.c: modified to accept MRI syntax, put back listing pseudo
12306 ops so that an assembler built with NO_LISTING ignores list ops
12308 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
12309 machine is a SPARC or a 29K.
12310 * config/obj-aout.c: added s_sect pseudo op
12311 * config/obj-coffbfd.c: lints, set the filehdr flags right and
12312 fill in the timestamp.
12313 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
12314 anymore, define all the relocs which the tc-<x> bit will use so we
12315 can translate from them to the coff types.
12316 * config/tc-a29k.c: reloc_type isn't ane enum any more
12317 * config/tc-m68k.c: Added NO_RELOC definition.
12319 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
12321 * Makefile.in: put header files before C source for TAGS; remove
12322 references to non-existent syscalls.h.
12324 * read.c, write.c subsegs.c: back out the .bss changes.
12326 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
12328 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
12330 * a.out.h: removed.
12332 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
12334 * symbols.c (local_label_name): symbols now start with ^A.
12336 * read.c, subsegs.c, write.c obj-coff.c: added handling of
12337 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
12338 generate these sections. .align: will use NOP_OPCODE or 0
12339 for padding. This is just for being nice to the
12342 * expr.c (operand): changed to generate local label "\001L0"
12343 starting with a ^A so that it is recognized as a local label.
12345 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
12347 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
12348 i/o opcodes - inb, inw, outb and outw. string manipulation with
12349 att syntax - scmp, slod, smov, ssca, ssto.
12351 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
12352 to just after .file .
12354 In obj_crawl_symbol_chain() where it tries to put the external
12355 symbols apart, with the condition:
12356 (!S_IS_DEFINED(symbolP) &&
12357 !S_IS_DEBUG(symbolP) &&
12358 !SF_GET_STATICS(symbolP))
12359 it was moving too many symbols out. So I switch it back to the
12361 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
12363 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
12364 so that we don't use the F_RELFLG which make the linker complain
12365 that somebody has stripped the relocation info.
12367 Also, the AIX ld program require that the relocation table
12368 is sorted by r_vaddr like the standard ATT assembler does.
12370 [he also changed the sizeof(struct ...)'s into the coff
12371 style FOOSZ macros. I'm not sure this is right, but I can't
12372 remember why. xoxorich.]
12374 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
12376 * Makefile.in, configure.in, doc: use the doc. Build it, install
12379 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
12381 * read.c: white space and comments only.
12383 * configure.in: use the new atof-ns32.c for ns32k.
12385 * write.c: comment change only.
12387 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
12388 aren't yet integrated.
12390 * tc-i860.[hc]: blew off the dust. Something must still be done
12391 about conflicting relocation types.
12393 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
12396 * tc-i960.c, tc-sparc.c: white space and comments only.
12398 * tc-a29k.h: delete duplicate macro definition.
12400 * new file atof-ns32k.c copied from hack's last unreleased gas.
12402 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
12404 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
12407 * nearly everything. flush ChangeLog, package as gas-1.92.1.
12408 ChangeLog's prior to this are sketchy at best. I have logs.
12409 They just aren't ChangeLogs.
