15 Fri Jun 3 23:35:36 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
17 * read.c (emit_expr): Use memset to zero out memory, rather than
18 going through md_number_to_chars. This permits handling symbolic
19 arguments when the size is larger than sizeof (valueT), if
20 TC_CONS_FIX_NEW is prepared to handle the case (as it is on MIPS).
22 Fri Jun 3 12:50:13 1994 David J. MacKenzie (djm@rtl.cygnus.com)

71 m68040_control_regs, m68060_control_regs): New arrays.
72 (control_regs): New pointer.
73 (m68k_ip): Use control_regs instead of testing CPU every time.

142 new VMS symbol-type macros; signed and unsigned quadword integers,
143 for `long long' support. Their values come from the existing
144 DSC$K_DTYPE_QU and DSC$K_DTYPE_Q macros in <descrip.h>. The
145 VMS debugger now recognizes `long long' variables correctly.
146 config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
147 for gcc2's predefined types "long double" (same as double, as
148 per gcc's current state), "long long int", "long long unsigned
149 int", and final `otherwise' case (to avoid uninitialized type
150 and size fields). [caveat: predefined types "complex int",
151 "complex float", "complex double", and "complex long double" are
154 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
155 of 0, because the latter indicates success rather than failure

161 allocating new symbol entry and linking it to VMS_Symbol_type_list.
163 Tue May 17 20:47:31 1994 Pat Rankin (rankin@eql.caltech.edu)
165 * config/obj-vms.c (Write_VMS_MHD_Records): don't try to interpret
166 the contents of the GAS_VERSION string when falling back to it for
167 language processor identification.
169 * make-gas.com, vmsconf.sh (ENVIRON): fix misspelling of
170 `psect_attr' in linker options.

193 * config/tc-hppa.c (pa_ip): Use R_HPPA_ABS_CALL, not R_HPPA for
196 Tue May 17 12:50:46 1994 Jeff Law (law@snake.cs.utah.edu)
198 * config/tc-hppa.c (pa_parse_fp_cmp_cond): Report an error
199 on a partial completer match.

540 argument, the reloc type.
541 (load_register): Pass reloc type to macro_build for 'u'.
542 (macro): Likewise. For M_LA_AB permit a difference expression

589 elf_tc_make_sections stuff. It was there to support PA braindamage
590 which has been fixed, and in the case of elf_tc_make_sections is
591 redundant with elf_tc_final_processing.

611 don't spew remainder of input file in error message.
612 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
613 message with reloc type and try to process remainder of file.
615 * doc/Makefile.in (install-info-as, install-info-gasp): New
616 targets, now explicitly checking $(srcdir) for info files.
617 (install-info): Depend on both of them; do nothing more.

625 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
626 flag rather than signedp field. Only permit extended range if
627 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
628 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
630 * config/tc-ppc.c (ppc_size): New static variable.
631 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
632 (md_begin): If an instruction has a size specific flag set, only
633 add it if we are assembling that size.
635 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
637 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
638 cross section PC relative relocs right for COFF and ELF.
640 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
642 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

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

665 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
666 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
668 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
669 branch with an instruction that uses $at, in case the branch is
671 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
672 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
673 to make it pcrel_offset.
674 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
675 reloc->address; another gruesome hack to get gas reloc handling to
678 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
680 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using

684 (md_assemble): Call it.
685 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
687 (lituse_pending): New variable. Set by anything that generates a
688 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
689 tested by code that might want to emit a LITUSE reloc.
690 (emit_unaligned_io): New function. Currently calls md_assemble,
691 but it should eventually be converted to generate the insn itself
692 and call emit_insn directly.
693 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
694 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
695 emit_bis_r): Likewise.

702 the value can't be resolved.
704 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
706 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
707 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

723 (load_address): Handle EMBEDDED_PIC.
724 (macro): Handle EMBEDDED_PIC in all PIC cases.
725 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
726 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
727 -non_shared to use NO_PIC (this is how the Irix 5 assembler
728 works). Do not permit -G with SVR4_PIC.
729 (s_abicalls): Warn if -G was used, and force -G 0.
730 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
731 anything but a.out, not just for ELF. For ECOFF, don't generate a
732 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
734 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
736 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

742 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
744 * Makefile.in (config-stamp): If `defs' is defined, emit a
745 preprocessor directive to create a macro named by this value into
746 config.new; don't explicitly go for BFD_ASSEMBLER.
747 * configure.in: Define `defs', not `BFDDEF'. Set it to
748 MANY_SEGMENTS for any obj-coffbfd target.
749 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
750 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
752 (LOCAL_LOADLIBES): Deleted.
753 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
754 * config/m88kcoff.mt (TDEFINES): Ditto.

780 bfd_set_symtab is called.
781 (dump_section_relocs): Note whether a symbol is a section symbol
783 (adjust_reloc_syms): For now, always supply an absolute symbol for
784 fixups without symbols but not yet `done'. Use section_symbol to
785 get the symbol, instead of going directly for abs_symbol.
786 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
787 reloc is not a section symbol and is not in the symbol table.
788 (set_symtab): New function, broken out from write_object_file.
789 Counts symbol table instead of relying on an earlier count.
790 (write_object_file): Call set_symtab, but do it after potentially
791 invoking the *_frob_file macros. Don't bother counting symbols.
792 Call symbol_remove, instead of expanding it in place. Moved the
793 conditionalized `object_file_size' declaration down to
794 conditionalized block where it's used. When using the absolute
795 symbol for a fixup without a symbol, set sy_used_in_reloc.
796 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
797 the correct symbol for the absolute section.
799 * subsegs.c (section_symbol): Use symbol_new instead of
800 symbol_make, since we may want it to go into the symbol table.
801 Make the new symbol have internal linkage. If
802 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
803 symbol with the newly created GAS symbol.
804 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
805 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

810 (in_signed_range): New function.
812 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
813 (sparc_ip, label "immediate"): Reject constants for pcrel
814 instructions only if the relocation type indicates a "call"
815 instruction and the offset is within range of a "jmpl %g0". If
816 it's not in range, use the absolute section symbol plus an offset.
817 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
819 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
821 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
824 * configure.in: Eliminated all targets using obj-coff but not
825 defining BFD_ASSEMBLER; I think all such targets that are
826 supported will be matched by real CPU-OS combinations earlier in
828 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
829 some comments about the dpx2 configuration, but left it disabled,
830 since it couldn't be reached before.
831 (target a29k-amd-ebmonold): Deleted.
833 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

841 the 'j' operand if there are no further alternatives for this
844 * config/obj-coffbfd.c (adjust_stab_section): Initialize
845 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
846 is not SEG_UNKNOWN rather than checking whether it is >= 0.
848 * config/tc-mips.c (mips_align): Take new argument, label, and use
849 it instead of global insn_label.
850 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
851 call to mips_emit_delay and pass it to mips_align.
853 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
855 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
857 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
858 argument to a .callinfo directive. Don't loop forever on errors.
860 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
861 use pre-defined registers as arguments.

865 * write.c (write_object_file): Check both S_IS_LOCAL and
866 S_IS_EXTERNAL when deciding whether to discard a symbol.
868 * config-gas.com: Scan Makefile.in, not version.c, for current
869 version number. Delete all versions of temp files when finished
870 with them. Create config.h.
872 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
873 values to reduce number of lookups with S_GET_VALUE. Skip debug

875 holger@botbso.rhein-main.de.)
876 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
877 field. (Also from Holger Teutsch.) Watch for a would-be register
878 mask that spans frags.
880 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
881 this_base, not line_base. (Patch from Andreas Arens,
882 ari@obelix.av.rwth-aachen.de.)
884 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
885 look local if they're exported or undefined. Used to be done for
888 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
889 Get it from the looked-up symbol, instead of using the string from
890 the input stream, which is no longer null-terminated.

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

955 (obj_coff_section): Declare.
956 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
957 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

959 silently compiling to do nothing.
960 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define only if
962 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

2643 an example of marker relocations.
2644 * write.c (write_relocs): Instead of assuming size of a relocation
2645 is 4 bytes, pick up the size from relocation itself.

2675 pass new argument for i, j and o cases.
2676 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2897 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2898 the table, require that the one without bit 0x1000000 set come
2899 first. Require further that it be case 'b' or 'P'. The a29k
2900 opcode table already meets these constraints.
2901 (machine_ip): When handling case 'i' or 'A', make sure that the

2953 * write.c (write_relocs): For relocs that are pc_relative and
2954 pcrel_offset and not partial_inplace, adjust reloc->addend to

3010 for keeping or rejecting configurations still under development;
3011 default is to assume production environment, and reject configs
3012 still being worked on. Mark Elf configurations (except sparc and
3013 i386) as developmental. Deleted cases matching some generic names
3014 in favor of more specific names. (E.g., when we get Alpha

3031 through inclusion of tc-hppa.h. Delete all forward declarations
3032 for functions only used within tc-hppa.c, likewise for structures,
3033 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
3034 conditional code in a few small places.
3036 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3037 structures, global variables, forward declarations together.

3039 conditional code -- try to group conditional code together
3040 into a few places. Make all functions and variables which
3041 are only used within tc-hppa.c static. PARAMize all functions.
3042 Add comments to functions. Delete unused functions, variables,
3043 #defines, etc. Delete unused members within structures. Delete
3044 ldil;ble hacks -- it is believed they were installed to work
3045 around old gas bugs. Avoid using mixed case for local
3046 functions, variables, and structures. Fix formatting problems
3047 not found by GNU-indent. Add FIXME notices for things which
3048 should be worked on the near future. Delete lots of old
3049 useless (1.36 PA-SOM) code.

3066 * config/tc-hppa.c: Likewise.
3068 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
3069 of elf32_symbol_type.
3070 (pa_export_args): Likewise.

3078 a multiple of the section alignment rather than always a
3081 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

3122 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3124 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3125 ELF, since the ELF object format does not have these type of
3126 relocations. Change the abort into as as_bad and return
3127 BFD_RELOC_NONE to silence compiler warnings.
3128 (md_assemble): Keep track of the instruction size. Allow white
3129 space between the $ and the constant for compatibility with older
3130 gases and other assemblers.
3131 (i386_operand): Skip spaces between $ and expression.
3132 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

4194 value is actually needed. This permits setting symbols to values
4195 calculated based on object code size. Expressions were changed to
4196 no longer be in a section, to stop the overloading of segment and
4197 expression type that previously occurred.
4199 * as.c (big_section, pass1_section, diff_section, absent_section):

5642 prototypes for all static functions. Moved existing minimal
5643 debugging format support info #ifndef OBJ_ECOFF blocks.

5694 * read.c (s_ignore): Don't declare is_end_of_line. It's
5695 redundant, and triggers a VMS gcc compiler bug.
5697 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5698 current segment as an argument. (Ignored in all cases but VMS.)
5699 All callers and definitions changed.

6016 (operand): Treat zero byte as end-of-operand.
6018 * configure.in (per-target): Look for with_bfd_assembler option.
6019 For now, only accept "no", until the merge is done.
6021 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
6022 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
6023 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
6024 * read.c: Finish conversion to S_* macros in the VMS only
6025 parts of the program. Add "const" modifier to hex_value.
6026 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
6028 * expr.c: Add "const" modifier to hex_value.
6029 * symbols.c: Finish conversion to S_* macros in the VMS only
6030 parts of the program. Add "const" modifier to
6031 md_[long,short]_jump_size. Remove declaration of const_flag
6032 (which will be declared in obj-vms.h).
6033 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6034 Fix arguments to VMS_write_object_file.
6035 * config-gas.com: New file. Script for VMS systems to set up the

6052 * obj-vms.c (VMS_write_object_file): Define all vtable psects
6053 as symbols as well in the object file. Look for external functions

6094 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
6095 mapping to segT enum values.
6096 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
6097 if these are used or defined, if BFD_ASSEMBLER.
6098 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6099 subseg_new split into two functions.

6102 * as.h (volatile): Don't define if already defined.
6103 (had_errors, had_warnings): Provide prototypes for ANSI C even if
6105 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
6106 declare with format attribute for -Wformat checking.
6108 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
6110 * app.c, config/tc-*.c: Don't include read.h, since it is already
6113 * These are based on patches from Minh Tran-le
6114 <mtranle@paris.intellicorp.com>.
6115 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
6116 obj_format coffbfd and gas_target i386coff for target.
6117 (i[34]86-*-isc*): New host (uses sysv).
6118 * config/i386aix.mt: Removed (no longer used).
6119 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
6121 (LDFLAGS): Added, defined as -shlib.
6122 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
6123 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6124 (DOT_LABEL_PREFIX): Define.
6125 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
6126 name rather than L0\001.
6127 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
6129 * symbols.c, symbols.h (local_bss_counter): Removed.
6130 * write.c (write_object_file): bss no longer uses
6131 local_bss_counter. Pass correct data and bss size to
6132 VMS_write_object_file.

6136 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
6137 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
6138 (size_section): Restored sanity check.
6139 (do_relocs_for): Base section address on s_paddr rather than
6140 computing it. Adjust a29k R_IHIHALF special case to account for
6141 section paddr (used to require paddr to be zero). If there are no
6142 reclos, set s_relptr to 0. Set relocation size in object_headers.
6143 (fill_section): Always set s_vaddr here, removing
6144 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6145 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6146 Set STYP_INFO for .comment.
6147 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
6148 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

6150 H_{SET,GET}_* macros.
6151 (do_linenos_for): Set lineno size in object_headers.
6152 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6153 set s_vaddr here. If string_byte_count remains 4, set it back to
6154 0, and only write strings out if there are some. Call
6155 fill_section before do_relocs_for and do_linenos_for.
6156 (obj_coff_section): Handle optional quoted second argument giving
6157 section characteristics.
6158 (obj_coff_bss): Added to handle .bss.
6159 (obj_coff_ident): Added to handle .ident (puts string in .comment
6161 (obj_coff_lcomm): Put common symbols in .bss, not .data.
6162 (fixup_mdeps): Change to segment. Call frag_wane after
6164 (fixup_segment): Explicitly check S_IS_COMMON before making 386
6165 adjustment (already happened only for common symbols, but this is
6167 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

6179 (do_scrub_next_char): For \", return " not '.
6180 (symbol_chars): Now const.
6182 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6183 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6185 * config/obj-coff.h: Don't use #elif.
6187 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6188 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
6190 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

6214 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6215 using ZERO_BASED_SEGMENTS.
6216 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6217 never set segment address for SEG_E2 (.bss) and don't write out
6218 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6219 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6220 definitions, and don't merge tags with non-tags. Check for .bf
6221 rather than just checking whether the second character is b and
6222 the third character is f.
6223 (obj_coff_val): gcc can generate values which we don't handle
6224 correctly; discard information for now, since it only affects the
6225 debugging information.
6226 (tag_find_or_name): Don't insert tags in the symbol table.
6227 (yank_symbols): Don't merge labels.
6228 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6234 relative addends by the segment vaddr.
6235 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
6236 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

6373 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
6374 could be doing emulation.
6376 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6379 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
6382 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
6384 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

6408 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6410 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6411 constant will not fit in an immediate field.
6412 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
6414 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

6447 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6449 * Support for i386-sysv.
6450 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6454 (fill_section): Don't set STYP_NOLOAD for .bss section.
6455 (fixup_segment): 386 uses strange common symbol format.

6474 * tc-m68k.c (get_num): make it work for all segments, not just the
6477 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
6479 * configure.in: recognize i386-*-bsd emulation.

6488 * tc-z8k.c: lots of bug fixes
6490 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6492 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6493 #elif, since it is not supported by old compilers.
6494 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6495 couple of expressions in tc-m68k.c.
6497 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6499 * read.c (cons): If NO_RELOC is defined, use it.
6501 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6503 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6505 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6506 local labels to start with a .) and set REGISTER_PREFIX to %.
6507 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6509 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
6511 * messages.c: Comment changes.
6513 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
6515 * as.h: Test if __STDC__ is defined only, don't test its value.
6516 * messages.c: If __STDC__ is not defined, define NO_STDARG.
6518 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
6520 * listing.c (debugging_pseudo): Add stabs and stabn as things to
6523 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6525 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6526 sections starting from zero, rather than making them consecutive.
6527 This makes subsequent reloc calculations easier, esp if the object
6528 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6529 allocate lcomm in .data rather than in .bss. It seems that some
6530 tools can't cope with a non-zero sized bss before linkage.
6532 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6534 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6535 throughout. That enum no longer means what we thought it meant.
6537 * tc-m68k.c (md_assemble, md_parse_option): Handle new
6538 "-mno-688[58]1" options.
6540 * tc-m68k.c: Added CPU32 support.
6542 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6544 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
6546 Tue Sep 15 17:25:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6548 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
6549 Change LIBDEPS dependence to LIBS.
6551 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6553 * Makefile.in (install): if $(tooldir) exists, install as in
6556 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6558 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6559 .word is < -32768 or > 32767. The -J flag causes the error to be
6560 ignored. This is to catch over-sized switches generated by gcc on
6561 systems which don't support the broken .word hack.
6562 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6563 write.c (fixup_segment): check for signed .word overflow if
6564 WARN_SIGNED_OVERFLOW_WORD.
6566 * write.c (fixup_segment): fixed missing parens in expression
6567 checking for byte or word overflow.
6569 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
6570 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
6571 WARN_SIGNED_OVERFLOW_WORD.

6574 expression checking for byte or word overflow.
6576 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)

7051 machine is a SPARC or a 29K.
7052 * config/obj-aout.c: added s_sect pseudo op
7053 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7054 fill in the timestamp.

7076 * symbols.c (local_label_name): symbols now start with ^A.
7078 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7079 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7080 generate these sections. .align: will use NOP_OPCODE or 0
7081 for padding. This is just for being nice to the
7084 * expr.c (operand): changed to generate local label "\001L0"
7085 starting with a ^A so that it is recognized as a local label.
7087 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7089 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7090 i/o opcodes - inb, inw, outb and outw. string manipulation with
7091 att syntax - scmp, slod, smov, ssca, ssto.
7093 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7094 to just after .file .
7096 In obj_crawl_symbol_chain() where it tries to put the external
7097 symbols apart, with the condition:
7098 (!S_IS_DEFINED(symbolP) &&
7099 !S_IS_DEBUG(symbolP) &&
7100 !SF_GET_STATICS(symbolP))
7101 it was moving too many symbols out. So I switch it back to the
7103 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7105 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7106 so that we don't use the F_RELFLG which make the linker complain
7107 that somebody has stripped the relocation info.
7109 Also, the AIX ld program require that the relocation table
7110 is sorted by r_vaddr like the standard ATT assembler does.
7112 [he also changed the sizeof(struct ...)'s into the coff
7113 style FOOSZ macros. I'm not sure this is right, but I can't
7114 remember why. xoxorich.]

7118 * Makefile.in, configure.in, doc: use the doc. Build it, install
7121 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
7123 * read.c: white space and comments only.
7125 * configure.in: use the new atof-ns32.c for ns32k.
7127 * write.c: comment change only.
7129 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7130 aren't yet integrated.
7132 * tc-i860.[hc]: blew off the dust. Something must still be done
7133 about conflicting relocation types.
7135 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7138 * tc-i960.c, tc-sparc.c: white space and comments only.
7140 * tc-a29k.h: delete duplicate macro definition.
7142 * new file atof-ns32k.c copied from hack's last unreleased gas.
7144 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7146 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7149 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7150 ChangeLog's prior to this are sketchy at best. I have logs.
7151 They just aren't ChangeLogs.
