1 Wed Jun 8 06:28:37 1994 Bill Cox (bill@cygnus.com)
3 * Makefile.in (check): Delete as.new dependency, so that

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

55 md_parse_option. Remove md_parse_long_option.
56 * config/tc-ns32k.c: Rename `struct option' to `struct ns32k_option'.
57 * config/tc-i386.h: Don't define md_parse_option.

76 m68040_control_regs, m68060_control_regs): New arrays.
77 (control_regs): New pointer.
78 (m68k_ip): Use control_regs instead of testing CPU every time.

82 m68851 choice. Set control_regs.
83 (md_parse_option): Handle "68060".
84 * configure.in: Setting cpu_type, recognize m68060 too.
86 * config/obj-coff.c (fixup_segment) [!BFD_ASSEMBLER]

118 Fri May 27 10:05:53 1994 Ken Raeburn (raeburn@cygnus.com)
120 Merged in changes from gas-2.3 net release:
122 * Makefile.in (VERSION): Updated to cygnus-2.3.1.

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

164 hardcoded `0xa3's with macro DBG_S_C_ADVANCED_TYPE from obj-vms.h.
165 (VMS_typedef_parse): eliminate redundant if-then-else when
166 allocating new symbol entry and linking it to VMS_Symbol_type_list.
168 Tue May 17 20:47:31 1994 Pat Rankin (rankin@eql.caltech.edu)
170 * config/obj-vms.c (Write_VMS_MHD_Records): don't try to interpret
171 the contents of the GAS_VERSION string when falling back to it for
172 language processor identification.
174 * make-gas.com, vmsconf.sh (ENVIRON): fix misspelling of
175 `psect_attr' in linker options.

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

442 all arguments have been processed.

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

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

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

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

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

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

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

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

727 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
728 (load_address): Handle EMBEDDED_PIC.
729 (macro): Handle EMBEDDED_PIC in all PIC cases.
730 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
731 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
732 -non_shared to use NO_PIC (this is how the Irix 5 assembler
733 works). Do not permit -G with SVR4_PIC.
734 (s_abicalls): Warn if -G was used, and force -G 0.
735 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
736 anything but a.out, not just for ELF. For ECOFF, don't generate a
737 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
739 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
741 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

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

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

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

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

870 * write.c (write_object_file): Check both S_IS_LOCAL and
871 S_IS_EXTERNAL when deciding whether to discard a symbol.
873 * config-gas.com: Scan Makefile.in, not version.c, for current
874 version number. Delete all versions of temp files when finished
875 with them. Create config.h.
877 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
878 values to reduce number of lookups with S_GET_VALUE. Skip debug
879 symbols to avoid "a really nasty bug". (From Holger Teutsch,
880 holger@botbso.rhein-main.de.)
881 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
882 field. (Also from Holger Teutsch.) Watch for a would-be register
883 mask that spans frags.
885 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
886 this_base, not line_base. (Patch from Andreas Arens,
887 ari@obelix.av.rwth-aachen.de.)
889 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
890 look local if they're exported or undefined. Used to be done for
893 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
894 Get it from the looked-up symbol, instead of using the string from
895 the input stream, which is no longer null-terminated.
896 (LEX_PCT): New macro, defaults to 0.
897 (lex_type): Use it for `%'.
899 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
900 (vip_op): Now static, and returns void. Callers changed. Added
902 (vip): Ditto. Call as_fatal directly if a program bug is

906 * Makefile.in (literal.o): Provide dependencies.
908 * configure.in: Set new makefile variable OPCODES_LIB.

960 (obj_coff_section): Declare.
961 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
962 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this
963 work. It still doesn't. It now fails to compile, instead of

2902 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2903 the table, require that the one without bit 0x1000000 set come
2904 first. Require further that it be case 'b' or 'P'. The a29k

2958 * write.c (write_relocs): For relocs that are pc_relative and
2959 pcrel_offset and not partial_inplace, adjust reloc->addend to

3015 for keeping or rejecting configurations still under development;
3016 default is to assume production environment, and reject configs
3017 still being worked on. Mark Elf configurations (except sparc and
3018 i386) as developmental. Deleted cases matching some generic names
3019 in favor of more specific names. (E.g., when we get Alpha

3036 through inclusion of tc-hppa.h. Delete all forward declarations
3037 for functions only used within tc-hppa.c, likewise for structures,
3038 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
3039 conditional code in a few small places.
3041 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3042 structures, global variables, forward declarations together.

3044 conditional code -- try to group conditional code together
3045 into a few places. Make all functions and variables which
3046 are only used within tc-hppa.c static. PARAMize all functions.
3047 Add comments to functions. Delete unused functions, variables,
3048 #defines, etc. Delete unused members within structures. Delete
3049 ldil;ble hacks -- it is believed they were installed to work
3050 around old gas bugs. Avoid using mixed case for local
3051 functions, variables, and structures. Fix formatting problems
3052 not found by GNU-indent. Add FIXME notices for things which
3053 should be worked on the near future. Delete lots of old
3054 useless (1.36 PA-SOM) code.

3066 which do not involve function symbols.
3068 * config/tc-hppa.h: Reindent with GNU-indent. Delete references

3071 * config/tc-hppa.c: Likewise.
3073 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
3074 of elf32_symbol_type.
3075 (pa_export_args): Likewise.
3076 (elf_hppa_final_processing): Likewise.

3082 * config/tc-hppa.c: (md_section_align): Align all sections to
3083 a multiple of the section alignment rather than always a
3086 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
3087 bits are zero (eg they specify no relocations), then do not even
3088 bother adding their entries to thesymextn section.

3127 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3129 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3130 ELF, since the ELF object format does not have these type of
3131 relocations. Change the abort into as as_bad and return
3132 BFD_RELOC_NONE to silence compiler warnings.
3133 (md_assemble): Keep track of the instruction size. Allow white
3134 space between the $ and the constant for compatibility with older
3135 gases and other assemblers.
3136 (i386_operand): Skip spaces between $ and expression.
3137 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

4197 * Extensive changes to permit symbols to contain any expression
4198 type and to delay the computation of the expression until the
4199 value is actually needed. This permits setting symbols to values
4200 calculated based on object code size. Expressions were changed to
4201 no longer be in a section, to stop the overloading of segment and
4202 expression type that previously occurred.

4290 (previous_section, previous_subsection): New vars.
4291 (obj_elf_section): Save current place in case DWARF code wants us
4292 to pop back to it. Handle unquoted section name as well as quoted
4293 section name. Don't crash on invalid strings.
4294 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

4406 sy_resolved and sy_resolving single bit fields.
4407 * symbols.c (symbol_new): Don't initialize sy_forward field.

5542 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5544 * Makefile.in: add dvi target; as-$(config).texinfo might live in

5596 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5598 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

5647 prototypes for all static functions. Moved existing minimal
5648 debugging format support info #ifndef OBJ_ECOFF blocks.

5699 * read.c (s_ignore): Don't declare is_end_of_line. It's
5700 redundant, and triggers a VMS gcc compiler bug.
5702 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5703 current segment as an argument. (Ignored in all cases but VMS.)
5704 All callers and definitions changed.

6021 (operand): Treat zero byte as end-of-operand.
6023 * configure.in (per-target): Look for with_bfd_assembler option.
6024 For now, only accept "no", until the merge is done.
6026 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
6027 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
6028 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
6029 * read.c: Finish conversion to S_* macros in the VMS only
6030 parts of the program. Add "const" modifier to hex_value.
6031 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
6033 * expr.c: Add "const" modifier to hex_value.
6034 * symbols.c: Finish conversion to S_* macros in the VMS only
6035 parts of the program. Add "const" modifier to
6036 md_[long,short]_jump_size. Remove declaration of const_flag
6037 (which will be declared in obj-vms.h).
6038 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6039 Fix arguments to VMS_write_object_file.
6040 * config-gas.com: New file. Script for VMS systems to set up the

6049 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6050 types of malformed stabs. Change parsing algorithm so that we are

6057 * obj-vms.c (VMS_write_object_file): Define all vtable psects
6058 as symbols as well in the object file. Look for external functions

6096 (section_alignment): Declare only if not BFD_ASSEMBLER.
6097 (big_section, reg_section, pass1_section, diff_section,
6098 absent_section, text_section, data_section, bss_section): If
6099 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
6100 mapping to segT enum values.
6101 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
6102 if these are used or defined, if BFD_ASSEMBLER.
6103 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old

6107 * as.h (volatile): Don't define if already defined.
6108 (had_errors, had_warnings): Provide prototypes for ANSI C even if
6110 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
6111 declare with format attribute for -Wformat checking.
6113 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
6115 * app.c, config/tc-*.c: Don't include read.h, since it is already
6118 * These are based on patches from Minh Tran-le
6119 <mtranle@paris.intellicorp.com>.
6120 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
6121 obj_format coffbfd and gas_target i386coff for target.
6122 (i[34]86-*-isc*): New host (uses sysv).
6123 * config/i386aix.mt: Removed (no longer used).
6124 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
6126 (LDFLAGS): Added, defined as -shlib.
6127 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
6128 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6129 (DOT_LABEL_PREFIX): Define.
6130 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
6131 name rather than L0\001.
6132 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
6134 * symbols.c, symbols.h (local_bss_counter): Removed.
6135 * write.c (write_object_file): bss no longer uses
6136 local_bss_counter. Pass correct data and bss size to
6137 VMS_write_object_file.

6141 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
6142 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
6143 (size_section): Restored sanity check.
6144 (do_relocs_for): Base section address on s_paddr rather than
6145 computing it. Adjust a29k R_IHIHALF special case to account for
6146 section paddr (used to require paddr to be zero). If there are no
6147 reclos, set s_relptr to 0. Set relocation size in object_headers.
6148 (fill_section): Always set s_vaddr here, removing
6149 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6150 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6151 Set STYP_INFO for .comment.
6152 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
6153 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

6155 H_{SET,GET}_* macros.
6156 (do_linenos_for): Set lineno size in object_headers.
6157 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6158 set s_vaddr here. If string_byte_count remains 4, set it back to
6159 0, and only write strings out if there are some. Call
6160 fill_section before do_relocs_for and do_linenos_for.
6161 (obj_coff_section): Handle optional quoted second argument giving
6162 section characteristics.
6163 (obj_coff_bss): Added to handle .bss.
6164 (obj_coff_ident): Added to handle .ident (puts string in .comment
6166 (obj_coff_lcomm): Put common symbols in .bss, not .data.
6167 (fixup_mdeps): Change to segment. Call frag_wane after
6169 (fixup_segment): Explicitly check S_IS_COMMON before making 386
6170 adjustment (already happened only for common symbols, but this is
6172 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

6183 * app.c (app_push): Use memcpy, not bcopy.
6184 (do_scrub_next_char): For \", return " not '.
6185 (symbol_chars): Now const.
6187 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6188 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6190 * config/obj-coff.h: Don't use #elif.
6192 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6193 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
6195 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

6219 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6220 using ZERO_BASED_SEGMENTS.
6221 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6222 never set segment address for SEG_E2 (.bss) and don't write out
6223 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6224 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6225 definitions, and don't merge tags with non-tags. Check for .bf
6226 rather than just checking whether the second character is b and
6227 the third character is f.
6228 (obj_coff_val): gcc can generate values which we don't handle
6229 correctly; discard information for now, since it only affects the
6230 debugging information.
6231 (tag_find_or_name): Don't insert tags in the symbol table.
6232 (yank_symbols): Don't merge labels.
6233 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6236 (obj_coff_section): Accept and ignore a trailing quoted string, as
6237 used in AT&T i386 syntax.
6238 (fixup_segment): Take segment as argument. On the i386, adjust PC
6239 relative addends by the segment vaddr.
6240 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
6241 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

6288 options. Updated options documentation for m68k. Some minor
6289 wording/punctuation changes.

6378 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
6379 could be doing emulation.
6381 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6384 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
6387 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
6389 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

6413 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6415 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6416 constant will not fit in an immediate field.
6417 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
6419 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

6452 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6454 * Support for i386-sysv.
6455 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6459 (fill_section): Don't set STYP_NOLOAD for .bss section.
6460 (fixup_segment): 386 uses strange common symbol format.

6479 * tc-m68k.c (get_num): make it work for all segments, not just the
6482 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
6484 * configure.in: recognize i386-*-bsd emulation.

6493 * tc-z8k.c: lots of bug fixes
6495 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6497 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6498 #elif, since it is not supported by old compilers.
6499 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6500 couple of expressions in tc-m68k.c.
6502 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6504 * read.c (cons): If NO_RELOC is defined, use it.
6506 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6508 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6510 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6511 local labels to start with a .) and set REGISTER_PREFIX to %.
6512 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6514 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
6516 * messages.c: Comment changes.
6518 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
6520 * as.h: Test if __STDC__ is defined only, don't test its value.
6521 * messages.c: If __STDC__ is not defined, define NO_STDARG.
6523 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
6525 * listing.c (debugging_pseudo): Add stabs and stabn as things to
6528 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6530 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6531 sections starting from zero, rather than making them consecutive.
6532 This makes subsequent reloc calculations easier, esp if the object
6533 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6534 allocate lcomm in .data rather than in .bss. It seems that some
6535 tools can't cope with a non-zero sized bss before linkage.
6537 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6539 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6540 throughout. That enum no longer means what we thought it meant.
6542 * tc-m68k.c (md_assemble, md_parse_option): Handle new
6543 "-mno-688[58]1" options.
6545 * tc-m68k.c: Added CPU32 support.
6547 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

6553 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
6554 Change LIBDEPS dependence to LIBS.
6556 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6558 * Makefile.in (install): if $(tooldir) exists, install as in
6561 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6563 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6564 .word is < -32768 or > 32767. The -J flag causes the error to be
6565 ignored. This is to catch over-sized switches generated by gcc on
6566 systems which don't support the broken .word hack.
6567 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6568 write.c (fixup_segment): check for signed .word overflow if
6569 WARN_SIGNED_OVERFLOW_WORD.
6571 * write.c (fixup_segment): fixed missing parens in expression
6572 checking for byte or word overflow.
6574 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

7056 machine is a SPARC or a 29K.
7057 * config/obj-aout.c: added s_sect pseudo op
7058 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7059 fill in the timestamp.

7071 * read.c, write.c subsegs.c: back out the .bss changes.
7073 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7075 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.

7081 * symbols.c (local_label_name): symbols now start with ^A.
7083 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7084 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7085 generate these sections. .align: will use NOP_OPCODE or 0
7086 for padding. This is just for being nice to the
7089 * expr.c (operand): changed to generate local label "\001L0"
7090 starting with a ^A so that it is recognized as a local label.
7092 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7094 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7095 i/o opcodes - inb, inw, outb and outw. string manipulation with
7096 att syntax - scmp, slod, smov, ssca, ssto.
7098 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7099 to just after .file .
7101 In obj_crawl_symbol_chain() where it tries to put the external
7102 symbols apart, with the condition:
7103 (!S_IS_DEFINED(symbolP) &&
7104 !S_IS_DEBUG(symbolP) &&
7105 !SF_GET_STATICS(symbolP))
7106 it was moving too many symbols out. So I switch it back to the
7108 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7110 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7111 so that we don't use the F_RELFLG which make the linker complain
7112 that somebody has stripped the relocation info.
7114 Also, the AIX ld program require that the relocation table
7115 is sorted by r_vaddr like the standard ATT assembler does.
7117 [he also changed the sizeof(struct ...)'s into the coff
7118 style FOOSZ macros. I'm not sure this is right, but I can't
7119 remember why. xoxorich.]

7123 * Makefile.in, configure.in, doc: use the doc. Build it, install
7126 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
7128 * read.c: white space and comments only.
7130 * configure.in: use the new atof-ns32.c for ns32k.
7132 * write.c: comment change only.
7134 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7135 aren't yet integrated.
7137 * tc-i860.[hc]: blew off the dust. Something must still be done
7138 about conflicting relocation types.
7140 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7143 * tc-i960.c, tc-sparc.c: white space and comments only.
7145 * tc-a29k.h: delete duplicate macro definition.
7147 * new file atof-ns32k.c copied from hack's last unreleased gas.
7149 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7151 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7154 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7155 ChangeLog's prior to this are sketchy at best. I have logs.
7156 They just aren't ChangeLogs.
