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

96 (last_movec_reg): New macro.
97 (m68000_control_regs, m68010_control_regs, m68020_control_regs,
98 m68040_control_regs, m68060_control_regs): New arrays.
99 (control_regs): New pointer.
100 (m68k_ip): Use control_regs instead of testing CPU every time.

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

169 new VMS symbol-type macros; signed and unsigned quadword integers,
170 for `long long' support. Their values come from the existing
171 DSC$K_DTYPE_QU and DSC$K_DTYPE_Q macros in <descrip.h>. The
172 VMS debugger now recognizes `long long' variables correctly.
173 config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
174 for gcc2's predefined types "long double" (same as double, as
175 per gcc's current state), "long long int", "long long unsigned
176 int", and final `otherwise' case (to avoid uninitialized type
177 and size fields). [caveat: predefined types "complex int",
178 "complex float", "complex double", and "complex long double" are
181 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
182 of 0, because the latter indicates success rather than failure

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

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

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

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

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

711 (md_assemble): Call it.
712 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
714 (lituse_pending): New variable. Set by anything that generates a
715 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
716 tested by code that might want to emit a LITUSE reloc.
717 (emit_unaligned_io): New function. Currently calls md_assemble,
718 but it should eventually be converted to generate the insn itself
719 and call emit_insn directly.
720 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
721 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
722 emit_bis_r): Likewise.

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

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

771 * Makefile.in (config-stamp): If `defs' is defined, emit a
772 preprocessor directive to create a macro named by this value into
773 config.new; don't explicitly go for BFD_ASSEMBLER.
774 * configure.in: Define `defs', not `BFDDEF'. Set it to
775 MANY_SEGMENTS for any obj-coffbfd target.
776 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
777 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
779 (LOCAL_LOADLIBES): Deleted.
780 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
781 * config/m88kcoff.mt (TDEFINES): Ditto.

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

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

868 the 'j' operand if there are no further alternatives for this
871 * config/obj-coffbfd.c (adjust_stab_section): Initialize
872 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
873 is not SEG_UNKNOWN rather than checking whether it is >= 0.
875 * config/tc-mips.c (mips_align): Take new argument, label, and use
876 it instead of global insn_label.
877 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
878 call to mips_emit_delay and pass it to mips_align.
880 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
882 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
884 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
885 argument to a .callinfo directive. Don't loop forever on errors.
887 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
888 use pre-defined registers as arguments.
890 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
892 * write.c (write_object_file): Check both S_IS_LOCAL and
893 S_IS_EXTERNAL when deciding whether to discard a symbol.
895 * config-gas.com: Scan Makefile.in, not version.c, for current
896 version number. Delete all versions of temp files when finished
897 with them. Create config.h.
899 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
900 values to reduce number of lookups with S_GET_VALUE. Skip debug

902 holger@botbso.rhein-main.de.)
903 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
904 field. (Also from Holger Teutsch.) Watch for a would-be register
905 mask that spans frags.
907 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
908 this_base, not line_base. (Patch from Andreas Arens,
909 ari@obelix.av.rwth-aachen.de.)
911 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
912 look local if they're exported or undefined. Used to be done for
915 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
916 Get it from the looked-up symbol, instead of using the string from
917 the input stream, which is no longer null-terminated.
918 (LEX_PCT): New macro, defaults to 0.
919 (lex_type): Use it for `%'.
921 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
922 (vip_op): Now static, and returns void. Callers changed. Added
924 (vip): Ditto. Call as_fatal directly if a program bug is

2670 an example of marker relocations.
2671 * write.c (write_relocs): Instead of assuming size of a relocation
2672 is 4 bytes, pick up the size from relocation itself.

2702 pass new argument for i, j and o cases.
2703 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2924 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2925 the table, require that the one without bit 0x1000000 set come
2926 first. Require further that it be case 'b' or 'P'. The a29k

3037 for keeping or rejecting configurations still under development;
3038 default is to assume production environment, and reject configs
3039 still being worked on. Mark Elf configurations (except sparc and
3040 i386) as developmental. Deleted cases matching some generic names
3041 in favor of more specific names. (E.g., when we get Alpha

3058 through inclusion of tc-hppa.h. Delete all forward declarations
3059 for functions only used within tc-hppa.c, likewise for structures,
3060 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
3061 conditional code in a few small places.
3063 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3064 structures, global variables, forward declarations together.

3066 conditional code -- try to group conditional code together
3067 into a few places. Make all functions and variables which
3068 are only used within tc-hppa.c static. PARAMize all functions.
3069 Add comments to functions. Delete unused functions, variables,
3070 #defines, etc. Delete unused members within structures. Delete
3071 ldil;ble hacks -- it is believed they were installed to work
3072 around old gas bugs. Avoid using mixed case for local
3073 functions, variables, and structures. Fix formatting problems
3074 not found by GNU-indent. Add FIXME notices for things which
3075 should be worked on the near future. Delete lots of old
3076 useless (1.36 PA-SOM) code.
3078 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
3079 field of the fixS structure. Needed to build unwind
3080 descriptors correctly.

3088 which do not involve function symbols.
3090 * config/tc-hppa.h: Reindent with GNU-indent. Delete references

3105 a multiple of the section alignment rather than always a
3108 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
3109 bits are zero (eg they specify no relocations), then do not even
3110 bother adding their entries to thesymextn section.

3149 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3151 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3152 ELF, since the ELF object format does not have these type of
3153 relocations. Change the abort into as as_bad and return
3154 BFD_RELOC_NONE to silence compiler warnings.
3155 (md_assemble): Keep track of the instruction size. Allow white
3156 space between the $ and the constant for compatibility with older
3157 gases and other assemblers.
3158 (i386_operand): Skip spaces between $ and expression.
3159 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

4219 * Extensive changes to permit symbols to contain any expression
4220 type and to delay the computation of the expression until the
4221 value is actually needed. This permits setting symbols to values
4222 calculated based on object code size. Expressions were changed to
4223 no longer be in a section, to stop the overloading of segment and
4224 expression type that previously occurred.
4226 * as.c (big_section, pass1_section, diff_section, absent_section):
4228 (expr_section): Added (used for dummy symbols which hold

4312 (previous_section, previous_subsection): New vars.
4313 (obj_elf_section): Save current place in case DWARF code wants us
4314 to pop back to it. Handle unquoted section name as well as quoted
4315 section name. Don't crash on invalid strings.
4316 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
4319 * config/obj-elf.h: Don't include struc-symbol.h.
4320 (obj_elf_frob_symbol): Declare arg as struct symbol *.

4404 (omagic): Removed unused variable.
4406 * Preliminary support for m88k-coff.

4428 sy_resolved and sy_resolving single bit fields.
4429 * symbols.c (symbol_new): Don't initialize sy_forward field.

5564 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5566 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5567 srcdir, might be in objdir.

5594 * config/tc-mips.c (macro): Use $AT if target register is zero in
5595 load instruction, which it can be for a floating point load.

5627 (ALL_CFLAGS): No longer define TARGET_CPU.
5629 * Makefile.in (check): Print a message, instead of quitting
5632 * as.c (main): Don't catch any signals, for now.

5669 prototypes for all static functions. Moved existing minimal
5670 debugging format support info #ifndef OBJ_ECOFF blocks.

5719 * make-gas.com: Find obstack.obj if it's not in the current
5721 * read.c (s_ignore): Don't declare is_end_of_line. It's
5722 redundant, and triggers a VMS gcc compiler bug.
5724 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5725 current segment as an argument. (Ignored in all cases but VMS.)
5726 All callers and definitions changed.

6039 * expr.c (operand): If character other than comma or newline is a
6040 logical end-of-line character, use the newline case.
6041 From Eric Youngdale:
6042 (operand): Set X_add_number field for floating-point numbers.
6043 (operand): Treat zero byte as end-of-operand.
6045 * configure.in (per-target): Look for with_bfd_assembler option.
6046 For now, only accept "no", until the merge is done.
6048 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
6049 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
6050 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
6051 * read.c: Finish conversion to S_* macros in the VMS only
6052 parts of the program. Add "const" modifier to hex_value.
6053 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
6055 * expr.c: Add "const" modifier to hex_value.
6056 * symbols.c: Finish conversion to S_* macros in the VMS only
6057 parts of the program. Add "const" modifier to
6058 md_[long,short]_jump_size. Remove declaration of const_flag
6059 (which will be declared in obj-vms.h).
6060 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6061 Fix arguments to VMS_write_object_file.
6062 * config-gas.com: New file. Script for VMS systems to set up the
6063 configuration to build gas for VMS, and create config.status.
6064 * make-gas.com: Redone to work with new scheme.
6065 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
6067 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
6068 will swap bytes if needed on a big endian system. Use throughout
6070 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
6071 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6072 types of malformed stabs. Change parsing algorithm so that we are
6073 more certain of having all of the information that we need on hand.
6074 * obj-vms.c (final_forward_reference): New function, used to help
6075 resolve the data types of as many struct elements as possible
6076 when some part of the struct is not fully defined by the compiler.
6077 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
6079 * obj-vms.c (VMS_write_object_file): Define all vtable psects
6080 as symbols as well in the object file. Look for external functions
6081 that start with "__vt.", and turn them into variables, since the
6082 g++ compiler is incapable of doing this.
6083 * tc-vax.c: Add '1' option for backward compatibility with older GCC
6085 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
6086 * input-scrub.c (as_where): Fix bug where as would crash if we did not

6107 * config/obj-coffbfd.h (segment_name): Ditto.
6109 * Changes for BFD_ASSEMBLER:
6110 * obj.h (obj_crawl_symbol_chain): Declare only if not
6112 (obj_header_append, obj_pre_write_hook): Ditto.
6113 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
6114 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

6119 (big_section, reg_section, pass1_section, diff_section,
6120 absent_section, text_section, data_section, bss_section): If
6121 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
6122 mapping to segT enum values.

6124 if these are used or defined, if BFD_ASSEMBLER.
6125 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old

6130 (had_errors, had_warnings): Provide prototypes for ANSI C even if
6132 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
6133 declare with format attribute for -Wformat checking.
6135 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
6137 * app.c, config/tc-*.c: Don't include read.h, since it is already
6140 * These are based on patches from Minh Tran-le
6141 <mtranle@paris.intellicorp.com>.
6142 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
6143 obj_format coffbfd and gas_target i386coff for target.
6144 (i[34]86-*-isc*): New host (uses sysv).
6145 * config/i386aix.mt: Removed (no longer used).
6146 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
6148 (LDFLAGS): Added, defined as -shlib.
6149 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
6150 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6151 (DOT_LABEL_PREFIX): Define.
6152 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
6153 name rather than L0\001.

6156 * symbols.c, symbols.h (local_bss_counter): Removed.
6157 * write.c (write_object_file): bss no longer uses

6165 (size_section): Restored sanity check.
6166 (do_relocs_for): Base section address on s_paddr rather than
6167 computing it. Adjust a29k R_IHIHALF special case to account for
6168 section paddr (used to require paddr to be zero). If there are no
6169 reclos, set s_relptr to 0. Set relocation size in object_headers.
6170 (fill_section): Always set s_vaddr here, removing
6171 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6172 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6173 Set STYP_INFO for .comment.

6178 (do_linenos_for): Set lineno size in object_headers.
6179 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6180 set s_vaddr here. If string_byte_count remains 4, set it back to
6181 0, and only write strings out if there are some. Call
6182 fill_section before do_relocs_for and do_linenos_for.
6183 (obj_coff_section): Handle optional quoted second argument giving
6184 section characteristics.
6185 (obj_coff_bss): Added to handle .bss.
6186 (obj_coff_ident): Added to handle .ident (puts string in .comment

6189 (fixup_mdeps): Change to segment. Call frag_wane after
6191 (fixup_segment): Explicitly check S_IS_COMMON before making 386
6192 adjustment (already happened only for common symbols, but this is
6194 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

6206 (do_scrub_next_char): For \", return " not '.
6207 (symbol_chars): Now const.
6209 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6210 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6212 * config/obj-coff.h: Don't use #elif.
6214 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6215 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
6217 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

6242 using ZERO_BASED_SEGMENTS.
6243 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6244 never set segment address for SEG_E2 (.bss) and don't write out
6245 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6246 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6247 definitions, and don't merge tags with non-tags. Check for .bf
6248 rather than just checking whether the second character is b and
6249 the third character is f.
6250 (obj_coff_val): gcc can generate values which we don't handle
6251 correctly; discard information for now, since it only affects the
6252 debugging information.

6254 (yank_symbols): Don't merge labels.
6255 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6400 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
6401 could be doing emulation.
6403 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6406 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6435 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6437 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6438 constant will not fit in an immediate field.
6439 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
6441 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

6514 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
6515 * tc-z8k.c: lots of bug fixes
6517 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6519 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6520 #elif, since it is not supported by old compilers.
6521 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6522 couple of expressions in tc-m68k.c.
6524 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6526 * read.c (cons): If NO_RELOC is defined, use it.
6528 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6530 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6532 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6533 local labels to start with a .) and set REGISTER_PREFIX to %.
6534 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6536 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
6538 * messages.c: Comment changes.

6550 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6552 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6553 sections starting from zero, rather than making them consecutive.
6554 This makes subsequent reloc calculations easier, esp if the object
6555 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6556 allocate lcomm in .data rather than in .bss. It seems that some
6557 tools can't cope with a non-zero sized bss before linkage.
6559 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6561 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

6583 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6585 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6586 .word is < -32768 or > 32767. The -J flag causes the error to be
6587 ignored. This is to catch over-sized switches generated by gcc on
6588 systems which don't support the broken .word hack.
6589 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6590 write.c (fixup_segment): check for signed .word overflow if

6620 From Steve Chamberlain:
6621 Makefile.in: Handle m68*-*-coff*.
6622 read.c, read.h: add mult argument to s_space
6624 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6625 Motorola and MIT syntax; gas can now assemble either type of

6669 * config/tc-m68k.c (init_table): Now const. Always include 68851
6670 data, so that "bc" is available to 68040 cache instructions.
6671 Added "tt0", "tt1", and 68ec030 variants.
6672 (md_assemble): Complain if 68000 (only) and 68881 are specified.

6701 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6702 has already been formatted (but may still contain %-characters).
6705 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6707 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6708 written with indirection on the last two operands, which can be
6709 either data or address registers. Added a new operand type 'r'
6710 which accepts either register type. Added '(' to notend stuff in
6711 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

7072 expressions. Also easier to read now.
7073 * listing.c: Put back defuns
7074 * read.c: modified to accept MRI syntax, put back listing pseudo
7075 ops so that an assembler built with NO_LISTING ignores list ops
7077 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7078 machine is a SPARC or a 29K.
7079 * config/obj-aout.c: added s_sect pseudo op
7080 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7081 fill in the timestamp.
7082 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7083 anymore, define all the relocs which the tc-<x> bit will use so we
7084 can translate from them to the coff types.
7085 * config/tc-a29k.c: reloc_type isn't ane enum any more
7086 * config/tc-m68k.c: Added NO_RELOC definition.

7090 * Makefile.in: put header files before C source for TAGS; remove
7091 references to non-existent syscalls.h.
7093 * read.c, write.c subsegs.c: back out the .bss changes.
7095 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7097 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.

7103 * symbols.c (local_label_name): symbols now start with ^A.
7105 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7106 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7107 generate these sections. .align: will use NOP_OPCODE or 0
7108 for padding. This is just for being nice to the
7111 * expr.c (operand): changed to generate local label "\001L0"
7112 starting with a ^A so that it is recognized as a local label.
7114 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7116 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7117 i/o opcodes - inb, inw, outb and outw. string manipulation with
7118 att syntax - scmp, slod, smov, ssca, ssto.
7120 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7121 to just after .file .
7123 In obj_crawl_symbol_chain() where it tries to put the external
7124 symbols apart, with the condition:
7125 (!S_IS_DEFINED(symbolP) &&
7126 !S_IS_DEBUG(symbolP) &&
7127 !SF_GET_STATICS(symbolP))
7128 it was moving too many symbols out. So I switch it back to the
7130 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7132 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7133 so that we don't use the F_RELFLG which make the linker complain
7134 that somebody has stripped the relocation info.
7136 Also, the AIX ld program require that the relocation table
7137 is sorted by r_vaddr like the standard ATT assembler does.
7139 [he also changed the sizeof(struct ...)'s into the coff
7140 style FOOSZ macros. I'm not sure this is right, but I can't
7141 remember why. xoxorich.]

7145 * Makefile.in, configure.in, doc: use the doc. Build it, install
7148 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
7150 * read.c: white space and comments only.
7152 * configure.in: use the new atof-ns32.c for ns32k.
7154 * write.c: comment change only.
7156 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7157 aren't yet integrated.
7159 * tc-i860.[hc]: blew off the dust. Something must still be done
7160 about conflicting relocation types.
7162 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7165 * tc-i960.c, tc-sparc.c: white space and comments only.
7167 * tc-a29k.h: delete duplicate macro definition.
7169 * new file atof-ns32k.c copied from hack's last unreleased gas.
7171 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7173 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7176 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7177 ChangeLog's prior to this are sketchy at best. I have logs.
7178 They just aren't ChangeLogs.
7182 version-control: never
