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

81 m68040_control_regs, m68060_control_regs): New arrays.
82 (control_regs): New pointer.
83 (m68k_ip): Use control_regs instead of testing CPU every time.

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

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

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

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

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

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

635 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
636 flag rather than signedp field. Only permit extended range if
637 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
638 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
640 * config/tc-ppc.c (ppc_size): New static variable.
641 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.

645 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
647 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
648 cross section PC relative relocs right for COFF and ELF.

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

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

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

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

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

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

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

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

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

876 S_IS_EXTERNAL when deciding whether to discard a symbol.
878 * config-gas.com: Scan Makefile.in, not version.c, for current
879 version number. Delete all versions of temp files when finished
880 with them. Create config.h.
882 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
883 values to reduce number of lookups with S_GET_VALUE. Skip debug

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

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

2364 make a final decision at the end of assembly when all
2365 information is known. Added PIC support for all symbol
2367 (mips_ip): Don't permit anything but a number after $ for a
2368 coprocessor register. Don't use .lit4 or .lit8 sections when

2376 if .cpload is not in noreorder section.
2377 (s_cprestore): Ignore .cprestore if not generating PIC code.
2378 (s_gpword, s_cpadd): New functions.
2379 (tc_get_register): Added frame argument; if true, set

2399 * Makefile.in (REAL_SOURCES): Added ecoff.c.
2400 (REAL_HEADERS): Added ecoff.h.
2401 (OBJS): Added ecoff.o.

2419 frag of type rs_machine_dependent rather than looking through
2422 * read.c (read_a_source_file): If we find a bad pseudo-op,
2423 do a continue to go on to the next line rather than a break.

2434 a zero size section.
2436 * write.c (write_relocs): In RELOC_EXPANSION_POSSIBLE case, base
2437 data offset on reloc[0]->address rather than reloc[j]->address, so

2440 * write.c (chain_frchains_together, relax_and_size_seg,
2441 adjust_reloc_syms, write_relocs): Make third argument PTR, not
2442 char *, to match definition of bfd_map_over_sections.

2445 as starting a CPP line directive unless it is a '#' and is the
2446 very first characters on the line (i.e., do not permit leading

2616 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
2617 standard hpux include files to pick up various function decls.
2619 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

2633 descriptor information to the BFD symbol.
2634 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

2653 an example of marker relocations.
2654 * write.c (write_relocs): Instead of assuming size of a relocation
2655 is 4 bytes, pick up the size from relocation itself.

2685 pass new argument for i, j and o cases.
2686 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2907 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2908 the table, require that the one without bit 0x1000000 set come
2909 first. Require further that it be case 'b' or 'P'. The a29k
2910 opcode table already meets these constraints.
2911 (machine_ip): When handling case 'i' or 'A', make sure that the

2963 * write.c (write_relocs): For relocs that are pc_relative and
2964 pcrel_offset and not partial_inplace, adjust reloc->addend to

3020 for keeping or rejecting configurations still under development;
3021 default is to assume production environment, and reject configs
3022 still being worked on. Mark Elf configurations (except sparc and
3023 i386) as developmental. Deleted cases matching some generic names
3024 in favor of more specific names. (E.g., when we get Alpha

3041 through inclusion of tc-hppa.h. Delete all forward declarations
3042 for functions only used within tc-hppa.c, likewise for structures,
3043 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
3044 conditional code in a few small places.
3046 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3047 structures, global variables, forward declarations together.

3049 conditional code -- try to group conditional code together
3050 into a few places. Make all functions and variables which
3051 are only used within tc-hppa.c static. PARAMize all functions.
3052 Add comments to functions. Delete unused functions, variables,
3053 #defines, etc. Delete unused members within structures. Delete
3054 ldil;ble hacks -- it is believed they were installed to work
3055 around old gas bugs. Avoid using mixed case for local
3056 functions, variables, and structures. Fix formatting problems
3057 not found by GNU-indent. Add FIXME notices for things which
3058 should be worked on the near future. Delete lots of old
3059 useless (1.36 PA-SOM) code.

3071 which do not involve function symbols.
3073 * config/tc-hppa.h: Reindent with GNU-indent. Delete references

3076 * config/tc-hppa.c: Likewise.
3078 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
3079 of elf32_symbol_type.
3080 (pa_export_args): Likewise.
3081 (elf_hppa_final_processing): Likewise.

3087 * config/tc-hppa.c: (md_section_align): Align all sections to
3088 a multiple of the section alignment rather than always a
3091 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
3092 bits are zero (eg they specify no relocations), then do not even
3093 bother adding their entries to thesymextn section.

3132 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3134 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3135 ELF, since the ELF object format does not have these type of
3136 relocations. Change the abort into as as_bad and return
3137 BFD_RELOC_NONE to silence compiler warnings.
3138 (md_assemble): Keep track of the instruction size. Allow white
3139 space between the $ and the constant for compatibility with older
3140 gases and other assemblers.
3141 (i386_operand): Skip spaces between $ and expression.
3142 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

4202 * Extensive changes to permit symbols to contain any expression
4203 type and to delay the computation of the expression until the
4204 value is actually needed. This permits setting symbols to values
4205 calculated based on object code size. Expressions were changed to
4206 no longer be in a section, to stop the overloading of segment and
4207 expression type that previously occurred.

4295 (previous_section, previous_subsection): New vars.
4296 (obj_elf_section): Save current place in case DWARF code wants us
4297 to pop back to it. Handle unquoted section name as well as quoted
4298 section name. Don't crash on invalid strings.
4299 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

4411 sy_resolved and sy_resolving single bit fields.
4412 * symbols.c (symbol_new): Don't initialize sy_forward field.

5652 prototypes for all static functions. Moved existing minimal
5653 debugging format support info #ifndef OBJ_ECOFF blocks.

5704 * read.c (s_ignore): Don't declare is_end_of_line. It's
5705 redundant, and triggers a VMS gcc compiler bug.
5707 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5708 current segment as an argument. (Ignored in all cases but VMS.)
5709 All callers and definitions changed.

6026 (operand): Treat zero byte as end-of-operand.
6028 * configure.in (per-target): Look for with_bfd_assembler option.
6029 For now, only accept "no", until the merge is done.
6031 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
6032 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
6033 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
6034 * read.c: Finish conversion to S_* macros in the VMS only
6035 parts of the program. Add "const" modifier to hex_value.
6036 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
6038 * expr.c: Add "const" modifier to hex_value.
6039 * symbols.c: Finish conversion to S_* macros in the VMS only
6040 parts of the program. Add "const" modifier to
6041 md_[long,short]_jump_size. Remove declaration of const_flag
6042 (which will be declared in obj-vms.h).
6043 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6044 Fix arguments to VMS_write_object_file.
6045 * config-gas.com: New file. Script for VMS systems to set up the
6046 configuration to build gas for VMS, and create config.status.

6054 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6055 types of malformed stabs. Change parsing algorithm so that we are

6062 * obj-vms.c (VMS_write_object_file): Define all vtable psects
6063 as symbols as well in the object file. Look for external functions

6113 (had_errors, had_warnings): Provide prototypes for ANSI C even if
6115 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
6116 declare with format attribute for -Wformat checking.
6118 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
6120 * app.c, config/tc-*.c: Don't include read.h, since it is already
6123 * These are based on patches from Minh Tran-le
6124 <mtranle@paris.intellicorp.com>.
6125 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
6126 obj_format coffbfd and gas_target i386coff for target.
6127 (i[34]86-*-isc*): New host (uses sysv).
6128 * config/i386aix.mt: Removed (no longer used).
6129 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
6131 (LDFLAGS): Added, defined as -shlib.
6132 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
6133 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6134 (DOT_LABEL_PREFIX): Define.
6135 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
6136 name rather than L0\001.
6137 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
6139 * symbols.c, symbols.h (local_bss_counter): Removed.
6140 * write.c (write_object_file): bss no longer uses
6141 local_bss_counter. Pass correct data and bss size to
6142 VMS_write_object_file.

6148 (size_section): Restored sanity check.
6149 (do_relocs_for): Base section address on s_paddr rather than
6150 computing it. Adjust a29k R_IHIHALF special case to account for
6151 section paddr (used to require paddr to be zero). If there are no
6152 reclos, set s_relptr to 0. Set relocation size in object_headers.
6153 (fill_section): Always set s_vaddr here, removing
6154 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6155 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6156 Set STYP_INFO for .comment.

6161 (do_linenos_for): Set lineno size in object_headers.
6162 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6163 set s_vaddr here. If string_byte_count remains 4, set it back to
6164 0, and only write strings out if there are some. Call
6165 fill_section before do_relocs_for and do_linenos_for.
6166 (obj_coff_section): Handle optional quoted second argument giving
6167 section characteristics.
6168 (obj_coff_bss): Added to handle .bss.
6169 (obj_coff_ident): Added to handle .ident (puts string in .comment
6171 (obj_coff_lcomm): Put common symbols in .bss, not .data.
6172 (fixup_mdeps): Change to segment. Call frag_wane after
6174 (fixup_segment): Explicitly check S_IS_COMMON before making 386
6175 adjustment (already happened only for common symbols, but this is
6177 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

6189 (do_scrub_next_char): For \", return " not '.
6190 (symbol_chars): Now const.
6192 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6193 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6195 * config/obj-coff.h: Don't use #elif.
6197 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6198 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

6225 using ZERO_BASED_SEGMENTS.
6226 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6227 never set segment address for SEG_E2 (.bss) and don't write out
6228 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6229 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6230 definitions, and don't merge tags with non-tags. Check for .bf
6231 rather than just checking whether the second character is b and
6232 the third character is f.
6233 (obj_coff_val): gcc can generate values which we don't handle
6234 correctly; discard information for now, since it only affects the
6235 debugging information.

6237 (yank_symbols): Don't merge labels.
6238 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6293 options. Updated options documentation for m68k. Some minor
6294 wording/punctuation changes.

6383 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
6384 could be doing emulation.
6386 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6389 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
6392 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
6394 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

6418 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6420 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6421 constant will not fit in an immediate field.
6422 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
6424 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

6457 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6459 * Support for i386-sysv.
6460 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6464 (fill_section): Don't set STYP_NOLOAD for .bss section.
6465 (fixup_segment): 386 uses strange common symbol format.

6484 * tc-m68k.c (get_num): make it work for all segments, not just the
6487 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
6489 * configure.in: recognize i386-*-bsd emulation.

6498 * tc-z8k.c: lots of bug fixes
6500 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6502 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6503 #elif, since it is not supported by old compilers.
6504 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6505 couple of expressions in tc-m68k.c.
6507 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6509 * read.c (cons): If NO_RELOC is defined, use it.
6511 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6513 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6515 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6516 local labels to start with a .) and set REGISTER_PREFIX to %.
6517 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6519 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
6521 * messages.c: Comment changes.
6523 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
6525 * as.h: Test if __STDC__ is defined only, don't test its value.
6526 * messages.c: If __STDC__ is not defined, define NO_STDARG.
6528 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
6530 * listing.c (debugging_pseudo): Add stabs and stabn as things to
6533 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6535 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6536 sections starting from zero, rather than making them consecutive.
6537 This makes subsequent reloc calculations easier, esp if the object
6538 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6539 allocate lcomm in .data rather than in .bss. It seems that some
6540 tools can't cope with a non-zero sized bss before linkage.
6542 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6544 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6545 throughout. That enum no longer means what we thought it meant.
6547 * tc-m68k.c (md_assemble, md_parse_option): Handle new
6548 "-mno-688[58]1" options.
6550 * tc-m68k.c: Added CPU32 support.
6552 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6554 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
6556 Tue Sep 15 17:25:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6558 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
6559 Change LIBDEPS dependence to LIBS.
6561 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6563 * Makefile.in (install): if $(tooldir) exists, install as in
6566 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6568 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6569 .word is < -32768 or > 32767. The -J flag causes the error to be
6570 ignored. This is to catch over-sized switches generated by gcc on
6571 systems which don't support the broken .word hack.
6572 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6573 write.c (fixup_segment): check for signed .word overflow if
6574 WARN_SIGNED_OVERFLOW_WORD.

7061 machine is a SPARC or a 29K.
7062 * config/obj-aout.c: added s_sect pseudo op
7063 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7064 fill in the timestamp.

7073 * Makefile.in: put header files before C source for TAGS; remove
7074 references to non-existent syscalls.h.
7076 * read.c, write.c subsegs.c: back out the .bss changes.
7078 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7080 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.

7086 * symbols.c (local_label_name): symbols now start with ^A.
7088 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7089 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7090 generate these sections. .align: will use NOP_OPCODE or 0
7091 for padding. This is just for being nice to the
7094 * expr.c (operand): changed to generate local label "\001L0"
7095 starting with a ^A so that it is recognized as a local label.
7097 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7099 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7100 i/o opcodes - inb, inw, outb and outw. string manipulation with
7101 att syntax - scmp, slod, smov, ssca, ssto.
7103 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7104 to just after .file .
7106 In obj_crawl_symbol_chain() where it tries to put the external
7107 symbols apart, with the condition:
7108 (!S_IS_DEFINED(symbolP) &&
7109 !S_IS_DEBUG(symbolP) &&
7110 !SF_GET_STATICS(symbolP))
7111 it was moving too many symbols out. So I switch it back to the
7113 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7115 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7116 so that we don't use the F_RELFLG which make the linker complain
7117 that somebody has stripped the relocation info.
7119 Also, the AIX ld program require that the relocation table
7120 is sorted by r_vaddr like the standard ATT assembler does.
7122 [he also changed the sizeof(struct ...)'s into the coff
7123 style FOOSZ macros. I'm not sure this is right, but I can't
7124 remember why. xoxorich.]

7128 * Makefile.in, configure.in, doc: use the doc. Build it, install
7131 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
7133 * read.c: white space and comments only.
7135 * configure.in: use the new atof-ns32.c for ns32k.
7137 * write.c: comment change only.
7139 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7140 aren't yet integrated.
7142 * tc-i860.[hc]: blew off the dust. Something must still be done
7143 about conflicting relocation types.
7145 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7148 * tc-i960.c, tc-sparc.c: white space and comments only.
7150 * tc-a29k.h: delete duplicate macro definition.
7152 * new file atof-ns32k.c copied from hack's last unreleased gas.
7154 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7156 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7159 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7160 ChangeLog's prior to this are sketchy at best. I have logs.
7161 They just aren't ChangeLogs.
