2884 (tc_gen_reloc): Simplify. It's no longer necessary to set a
2885 reloc's addend field to zero for function symbols.
2886 (md_apply_fix): Simplify. For fixups which will require a SOM
2887 reloc, just clear out the necessary bits in the output file.

2907 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
2908 it's better to use the one in libiberty.
2910 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2912 * symbols.c (resolve_symbol_value, case O_symbol): Undo last

2950 * Makefile.in (comparison): When comparing as.new or gasp.new, try
2951 running the binary through sed to avoid differences due to

2970 ecoff_frob_symbol if appropriate.
2972 * write.c (fixup_segment): For i386 elf and coff (for now), don't

3076 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3078 * configure.in: Set bfd_gas for all sparc targets in one place,
3079 instead of separately for each. Correctly handle user-supplied
3080 "--enable-bfd-gas" option.
3082 * gdbinit.in: Move "break abort" to end, in case gdb complains.
3084 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:

3092 (indent_level): No longer static.
3093 (print_symbol_value_1): Don't print frag address if it matches

3097 (print_expr_1): Fix whitespace before printing X_add_number.
3099 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
3100 not symbol_new, for symbols holding expression values.

3102 * write.c (fix_new_exp): Handle O_add by creating an
3103 expression-valued symbol, and calling fix_new_exp recursively.
3104 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
3105 undefined symbol and a constant, fold the constant into the fixup,
3106 and refer to the undefined symbol directly. Then process the
3107 fixup again from scratch.
3108 (write_object_file): Before calling adjust_reloc_syms, make a pass
3109 through the symbol list trying to resolve values.
3111 * write.c (print_fixup): New routine, for debugging.
3112 (write_relocs): Call bfd_install_relocation. Deleted various

3130 * write.c (write_relocs): Add file name and line number to
3131 as_fatal calls. Handle bfd_reloc_overflow case specifically when
3132 RELOC_EXPANSION_POSSIBLE.
3134 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3136 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
3137 here. Use them for deciding which PRINTF*LIKE macro definitions

3140 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
3141 default definitions matching what we were doing before.
3142 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
3143 always use the varargs form if not using stdarg. It's safe to
3144 always use vfprintf, because libiberty will provide it if the
3145 native system doesn't. Also, always make format be const.
3146 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

3164 false (if defined) as well as checking for reg_section.
3165 (listing_listing): Iterate fetching lines while line number is too
3166 low, and we haven't run off the end of the input file.
3168 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
3170 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

3186 X_add_number is zero.
3187 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
3189 * config/tc-i960.c: Lots of whitespace, comment reformatting,
3191 (strchr): Don't declare.

3193 md_estimate_size_before_relax, md_ri_to_chars,
3194 md_create_short_jump, md_create_long_jump.
3195 (brtab_emit): Use data_section, not SEG_DATA.
3197 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3199 * config/vms-conf.h: new file, manually derived from conf.in.
3200 * config-gas.com: use it, and eliminate obsolete "host.h".

3213 * config/tc-mips.c (insns_since_cache_access): Remove.
3214 (append_insn): Remove setting of insns_since_cache_access, and
3215 special 4600 handling; it turns out not to be required.
3217 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3219 * config/tc-mips.c (md_shortopts): Remove E.
3220 (md_longopts): Add EB and EL.
3221 (md_parse_option): Handle -EB and -EL as separate options, rather
3222 than as a single -E option with an argument.

3226 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
3227 involving global symbols too.
3229 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3231 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
3233 * configure.in: Test for remove, not delete. Fix cross-assembler

3249 representation (only enum bitfields can avoid being bitstrings).
3250 (bitfield_suffix, setup_basic_type): new routines.
3251 (VMS_typedef_parse): use them. Now recognize bitfields of all
3252 integral types, not just type `int'. Caveat: the representation
3253 used for bitfields still does not work for objects placed in
3254 registers, and gcc's optimizer sometimes puts small structs there.
3256 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3258 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
3259 bit from const_flag.
3260 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.

3266 (vms_check_for_special_label): new routine (tc_frob_label).
3267 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
3268 and `gcc2_compiled.' labels; they won't reach here any more.
3269 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
3270 double', use `vax_g_doubles' flag to select type of double.
3271 (VMS_write_object_file) [traceback setup]: don't pass symbols
3272 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin

3278 S_GET_VALUE() to avoid many repeated function calls.
3279 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
3280 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
3281 gets requested. [All the HACK_DEC_C_STARTUP code appears to
3282 be obsolete; gcc does it automatically for vms target. It's
3283 also misnamed, because it is for the "VAX C" run-time library,
3284 not the newer "DEC C" one which has much different startup code.]
3285 {various}: use `S_SET_xxx(symbol,new_value)' rather than
3286 `S_GET_xxx(symbol) = new_value'.

3311 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
3312 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
3313 pointer to 32 bits of unwind info.
3314 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
3315 pointer to the dummy symbol; set the addend field to fx_addnumber.

3335 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
3336 for O_big literal operands (double floats and long long ints);
3337 [VMS, md_shortopts]: add second colon after 'v';
3338 (md_parse_options) [VMS, case 'v']: check for argument, so

3537 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
3538 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
3539 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
3540 message to try to ease confusion about autoconf's

4287 Mon Jun 13 12:08:52 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4289 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
4290 to put a common symbol in a set.

4335 * read.c (emit_expr): Use memset to zero out memory, rather than
4336 going through md_number_to_chars. This permits handling symbolic

4390 (control_regs): New pointer.
4391 (m68k_ip): Use control_regs instead of testing CPU every time.
4392 Use last_movec_reg too. In error messages, handle 68060, and
4393 print 68060 for mfloat, too.
4394 (m68k_init_after_args): Handle "68060". Use m68040up for making
4395 m68851 choice. Set control_regs.

4764 * config/tc-mips.c (append_insn): Permit branches to be switched
4765 with the preceding instruction even if .set nobopt has been seen.
4766 .set nobopt actually controls whether to bring up an instruction

4907 elf_tc_make_sections stuff. It was there to support PA braindamage
4908 which has been fixed, and in the case of elf_tc_make_sections is
4909 redundant with elf_tc_final_processing.

5012 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

5046 works). Do not permit -G with SVR4_PIC.
5047 (s_abicalls): Warn if -G was used, and force -G 0.
5048 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for

5105 reloc is not a section symbol and is not in the symbol table.
5106 (set_symtab): New function, broken out from write_object_file.
5107 Counts symbol table instead of relying on an earlier count.
5108 (write_object_file): Call set_symtab, but do it after potentially
5109 invoking the *_frob_file macros. Don't bother counting symbols.
5110 Call symbol_remove, instead of expanding it in place. Moved the
5111 conditionalized `object_file_size' declaration down to
5112 conditionalized block where it's used. When using the absolute
5113 symbol for a fixup without a symbol, set sy_used_in_reloc.
5114 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
5115 the correct symbol for the absolute section.
5117 * subsegs.c (section_symbol): Use symbol_new instead of

5121 symbol with the newly created GAS symbol.

5131 (sparc_ip, label "immediate"): Reject constants for pcrel
5132 instructions only if the relocation type indicates a "call"
5133 instruction and the offset is within range of a "jmpl %g0". If
5134 it's not in range, use the absolute section symbol plus an offset.
5135 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
5137 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
5139 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
5142 * configure.in: Eliminated all targets using obj-coff but not
5143 defining BFD_ASSEMBLER; I think all such targets that are
5144 supported will be matched by real CPU-OS combinations earlier in
5146 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
5147 some comments about the dpx2 configuration, but left it disabled,
5148 since it couldn't be reached before.

5167 it instead of global insn_label.
5168 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
5169 call to mips_emit_delay and pass it to mips_align.

5193 holger@botbso.rhein-main.de.)
5194 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER

7368 Add comments to functions. Delete unused functions, variables,
7369 #defines, etc. Delete unused members within structures. Delete
7370 ldil;ble hacks -- it is believed they were installed to work
7371 around old gas bugs. Avoid using mixed case for local
7372 functions, variables, and structures. Fix formatting problems
7373 not found by GNU-indent. Add FIXME notices for things which

8537 * Extensive changes to permit symbols to contain any expression
8538 type and to delay the computation of the expression until the
8539 value is actually needed. This permits setting symbols to values
8540 calculated based on object code size. Expressions were changed to
8541 no longer be in a section, to stop the overloading of segment and
8542 expression type that previously occurred.
8544 * as.c (big_section, pass1_section, diff_section, absent_section):
8546 (expr_section): Added (used for dummy symbols which hold

8632 to pop back to it. Handle unquoted section name as well as quoted
8633 section name. Don't crash on invalid strings.

8746 sy_resolved and sy_resolving single bit fields.
8747 * symbols.c (symbol_new): Don't initialize sy_forward field.

9781 than ECOFF line number information.
9782 (obj_ecoff_stab): Accept non-zero values for stabs line number.

9861 (srcdir): Delete second, bogus definition.
9862 (as.info): Look for as-*.texinfo in current directory rather than
9866 * doc/configure.in: Create links to all as-*.texinfo files in the
9867 source directory, if that's not the current directory.
9869 * configure.in (per-host): Accept MIPS host with BSD version

9890 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
9891 process relocs if there aren't any relocs to process. Avoids
9892 malloc/free bug on SCO too.

9895 avoid some redefinition complaints on some systems.
9896 (const, volatile): Don't need these conditionally defined if we
9897 use CONST and VOLATILE from ansidecl.h.
9898 (seg_name): Use CONST, not const.
9900 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
9902 * config/tc-mips.c: Reindented to GNU standards.
9904 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
9906 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
9907 (fixup_segment): Add a29k special case; the linker is not prepared
9908 to see a segment offset here.
9910 * app.c (do_scrub_next_char): Added new state, 10, modifying state
9911 9 to only keep a space in between identifier characters.
9913 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
9915 * Makefile.in: add dvi target; as-$(config).texinfo might live in
9916 srcdir, might be in objdir.
9918 * doc/Makefile.in: dvi depends on as.dvi

9941 * Makefile.in (targ-cpu.o): Depend on config.h.
9943 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
9945 * app.c (do_scrub_next_char): Added new state, 9, to avoid
9946 dropping a space immediately following an identifier.
9947 * expr.c, write.c: Rewrote assert expressions to not use multiple
9948 lines; I don't think that can be done portably.
9949 * config/tc-mips.c (macro): Use $AT if target register is zero in
9950 load instruction, which it can be for a floating point load.

9963 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
9964 z8k-opc.h, not z8k.h.
9966 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
9969 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9971 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
9973 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)

10024 prototypes for all static functions. Moved existing minimal
10025 debugging format support info #ifndef OBJ_ECOFF blocks.
10026 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
10027 does not support a non sign extended high 16 bits reloc. Adjusted
10028 all callers accordingly.

10074 * make-gas.com: Find obstack.obj if it's not in the current
10076 * read.c (s_ignore): Don't declare is_end_of_line. It's
10077 redundant, and triggers a VMS gcc compiler bug.
10079 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
10080 current segment as an argument. (Ignored in all cases but VMS.)
10081 All callers and definitions changed.
10083 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
10085 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING

10097 (obj_elf_xstab): New routine.
10098 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
10099 argument to s_ignore. Put "#if 0" around unused code.
10100 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
10101 Call elf_xstabs for .stabs and .xstabs operators.
10103 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
10105 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
10108 * configure.in: mips-bsd configuration was missing format spec.
10111 * Makefile.in (Makefile): Depends on configure.in.
10113 * config/tc-mips.c (append_insn): Don't check for alignment of
10114 frag in memory; alignment of instructions in section is a separate

10134 * config/tc-sparc.c (s_xword): Now call big_cons, so large
10135 constants are accepted, but symbolic values are not. GCC will not
10136 generate the latter currently.
10138 * frags.c (frag_init): New function.
10139 (zero_address_frag, bss_address_frag): Now initialized at run

10173 referencing symbol structure members.
10174 (obj_aout_frob_symbol) [BFD_ASSEMBLER]: New function.
10176 * as.h (struct frag): Reordered a couple of fields for better

10182 (write_object_file) [BFD_ASSEMBLER]: Always handle -R here. Call
10183 fix_new with BFD_RELOC_NONE instead of 0 or NO_RELOC. Call
10184 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
10185 (fixup_segment): Make sure common-section symbols get treated the
10186 same as undefined symbols.
10187 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type
10188 bfd_reloc_code_real_type. Use seg_fix_{root,tail}P derived from
10190 * write.h (fix_new): Update prototype.
10192 * tc.h (md_operand, md_convert_frag, tc_headers_hook,
10193 md_section_align, md_undefined_symbol): Don't provide prototypes
10194 if these are defined as macros.
10195 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and
10198 * symbols.c (symbol_new): Argument NAME is now pointer to const.

10214 (subseg_new) [BFD_ASSEMBLER]: Rewritten to change to new section,
10215 given section name and subseg number.
10216 (subseg_set) [BFD_ASSEMBLER]: New function; change to a possibly
10217 new section/subsection.
10219 * read.c: Don't include ctype.h.
10220 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
10221 for now; should be machine-dependent.
10223 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
10224 targets, forcing BFD use.
10226 Wed Feb 17 18:59:03 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
10228 * config/tc-sparc.c: Use PARAMS macro for static function

10391 * config/tc-sparc.c (architecture_requested, warn_on_bump,
10392 md_relax_table): Use default zero initialization.
10393 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

10406 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
10408 * expr.c (operand): If character other than comma or newline is a
10409 logical end-of-line character, use the newline case.
10410 From Eric Youngdale:
10411 (operand): Set X_add_number field for floating-point numbers.
10412 (operand): Treat zero byte as end-of-operand.
10414 * configure.in (per-target): Look for with_bfd_assembler option.
10415 For now, only accept "no", until the merge is done.
10417 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
10418 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
10419 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
10420 * read.c: Finish conversion to S_* macros in the VMS only
10421 parts of the program. Add "const" modifier to hex_value.
10422 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
10424 * expr.c: Add "const" modifier to hex_value.
10425 * symbols.c: Finish conversion to S_* macros in the VMS only
10426 parts of the program. Add "const" modifier to
10427 md_[long,short]_jump_size. Remove declaration of const_flag
10428 (which will be declared in obj-vms.h).
10429 * write.c: Add "const" modifier to md_[long,short]_jump_size.
10430 Fix arguments to VMS_write_object_file.
10431 * config-gas.com: New file. Script for VMS systems to set up the
10432 configuration to build gas for VMS, and create config.status.
10433 * make-gas.com: Redone to work with new scheme.
10434 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
10436 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
10437 will swap bytes if needed on a big endian system. Use throughout
10439 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
10440 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
10441 types of malformed stabs. Change parsing algorithm so that we are
10442 more certain of having all of the information that we need on hand.
10443 * obj-vms.c (final_forward_reference): New function, used to help
10444 resolve the data types of as many struct elements as possible
10445 when some part of the struct is not fully defined by the compiler.
10446 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
10448 * obj-vms.c (VMS_write_object_file): Define all vtable psects
10449 as symbols as well in the object file. Look for external functions

10459 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
10461 * read.c (s_data): Always use "data_section", since it'll map to
10462 SEG_DATA or SEG_E1 if needed.
10463 (s_lcomm): Likewise with bss_section.
10464 (s_fill): Use memset, not bzero.
10466 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

10486 (seg_name): Declare only if not BFD_ASSEMBLER.
10487 (section_alignment): Declare only if not BFD_ASSEMBLER.
10488 (big_section, reg_section, pass1_section, diff_section,
10489 absent_section, text_section, data_section, bss_section): If
10490 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
10491 mapping to segT enum values.
10492 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
10493 if these are used or defined, if BFD_ASSEMBLER.
10494 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
10495 subseg_new split into two functions.
10496 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.

10510 <mtranle@paris.intellicorp.com>.
10511 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
10512 obj_format coffbfd and gas_target i386coff for target.
10513 (i[34]86-*-isc*): New host (uses sysv).
10514 * config/i386aix.mt: Removed (no longer used).
10515 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
10516 (MINUS_G): Removed.
10517 (LDFLAGS): Added, defined as -shlib.
10518 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
10519 * config/te-sco386.h (LOCAL_LABEL): Don't define.
10520 (DOT_LABEL_PREFIX): Define.
10521 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label

10525 * symbols.c, symbols.h (local_bss_counter): Removed.
10526 * write.c (write_object_file): bss no longer uses
10527 local_bss_counter. Pass correct data and bss size to
10528 VMS_write_object_file.
10529 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
10530 argument, rather than using local_bss_counter.

10534 (size_section): Restored sanity check.
10535 (do_relocs_for): Base section address on s_paddr rather than
10536 computing it. Adjust a29k R_IHIHALF special case to account for
10537 section paddr (used to require paddr to be zero). If there are no
10538 reclos, set s_relptr to 0. Set relocation size in object_headers.
10539 (fill_section): Always set s_vaddr here, removing
10540 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
10541 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
10542 Set STYP_INFO for .comment.
10543 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
10544 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

10547 (do_linenos_for): Set lineno size in object_headers.
10548 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
10549 set s_vaddr here. If string_byte_count remains 4, set it back to
10550 0, and only write strings out if there are some. Call
10551 fill_section before do_relocs_for and do_linenos_for.
10552 (obj_coff_section): Handle optional quoted second argument giving
10553 section characteristics.
10554 (obj_coff_bss): Added to handle .bss.
10555 (obj_coff_ident): Added to handle .ident (puts string in .comment

10575 (do_scrub_next_char): For \", return " not '.
10576 (symbol_chars): Now const.
10578 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
10579 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
10581 * config/obj-coff.h: Don't use #elif.
10583 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
10584 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
10586 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
10588 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

10606 * Changes to support SCO 3.2v4:
10607 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
10608 SEG_BSS, fill with NOP_OPCODE.
10609 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
10610 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
10611 using ZERO_BASED_SEGMENTS.
10612 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
10613 never set segment address for SEG_E2 (.bss) and don't write out
10614 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
10615 (obj_coff_endef): Don't merge labels or symbols awaiting forward
10616 definitions, and don't merge tags with non-tags. Check for .bf
10617 rather than just checking whether the second character is b and
10618 the third character is f.
10619 (obj_coff_val): gcc can generate values which we don't handle
10620 correctly; discard information for now, since it only affects the
10621 debugging information.
10622 (tag_find_or_name): Don't insert tags in the symbol table.
10623 (yank_symbols): Don't merge labels.
10624 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

10644 power-of-two alignment for .align.
10646 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
10647 and leave everything else alone.

10774 z8000 documentation
10775 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
10778 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
10780 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
10782 * subsegs.h: add extern to segment_info declaration.
10784 * read.h: added extern declarations for comment_chars,
10785 line_comment_chars, and line_separator_chars.
10786 read.c, app.c: removed definitions of comment_chars,
10787 line_comment_chars, and line_separator_chars.

10806 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
10807 constant will not fit in an immediate field.

10812 * obj-coff.c (callj_table): Delete global variable.
10813 (obj_emit_relocations): Define it locally here, and only if
10814 TC_I960 is defined.
10816 * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.

10845 * Support for i386-sysv.
10846 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
10847 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
10848 be used to set them all to zero as was done before.
10849 (fill_section): segment addresses now set in write_object_file.
10850 (fill_section): Don't set STYP_NOLOAD for .bss section.
10851 (fixup_segment): 386 uses strange common symbol format.

10888 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
10889 #elif, since it is not supported by old compilers.
10890 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
10891 couple of expressions in tc-m68k.c.
10893 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10895 * read.c (cons): If NO_RELOC is defined, use it.

10901 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
10902 local labels to start with a .) and set REGISTER_PREFIX to %.
10903 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
10905 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
10907 * messages.c: Comment changes.
10909 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

10912 * messages.c: If __STDC__ is not defined, define NO_STDARG.
10914 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
10916 * listing.c (debugging_pseudo): Add stabs and stabn as things to
10919 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
10921 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
10922 sections starting from zero, rather than making them consecutive.
10923 This makes subsequent reloc calculations easier, esp if the object
10924 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
10925 allocate lcomm in .data rather than in .bss. It seems that some
10926 tools can't cope with a non-zero sized bss before linkage.
10928 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10930 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10931 throughout. That enum no longer means what we thought it meant.
10933 * tc-m68k.c (md_assemble, md_parse_option): Handle new
10934 "-mno-688[58]1" options.
10936 * tc-m68k.c: Added CPU32 support.
10938 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

10949 * Makefile.in (install): if $(tooldir) exists, install as in
10952 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10954 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10955 .word is < -32768 or > 32767. The -J flag causes the error to be
10956 ignored. This is to catch over-sized switches generated by gcc on
10957 systems which don't support the broken .word hack.
10958 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10959 write.c (fixup_segment): check for signed .word overflow if
10960 WARN_SIGNED_OVERFLOW_WORD.
10962 * write.c (fixup_segment): fixed missing parens in expression
10963 checking for byte or word overflow.
10965 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
10966 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
10967 WARN_SIGNED_OVERFLOW_WORD.
10969 * obj-coffbfd.c (fixup_segment): fixed missing parens in
10970 expression checking for byte or word overflow.

10975 * obj-coffbfd.h : added stuff
10976 * tc-i386.c (tc_coff_fix2rtype): new function
10977 * tc-i386.h : new coff defines
10979 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
10981 * input-scrub.c (input_scrub_push): call input_file_begin, not
10983 messages.c (as_perror): print ": " between the passed in error and
10984 the strerror, like perror does.
10986 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

10993 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
10994 Motorola and MIT syntax; gas can now assemble either type of
10996 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
10997 From Steve Chamberlain:
10998 m68kcoff.mt: for m68k COFF.
10999 obj-coffbfd.c: (fixup_mdeps) added
11000 (size_section) removed bad sanity check
11001 (fill_section) added rs_machine_dependent case
11002 (write_object_file) call fixup_mdeps
11003 (fixup_segment) set fx_subsy to 0.
11004 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
11006 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
11009 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

11032 * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
11033 tc-i960.c (md_ri_to_chars): Always output bout object file in
11034 little endian byte order (used to use endianness of host).
11036 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11038 * config/tc-m68k.c (init_table): Now const. Always include 68851
11039 data, so that "bc" is available to 68040 cache instructions.
11040 Added "tt0", "tt1", and 68ec030 variants.
11041 (md_assemble): Complain if 68000 (only) and 68881 are specified.
11042 (enum _register): Added TT0, TT1.
11043 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
11044 line number correctly in "internal error" messages. Don't print
11045 architecture-mismatch message for operand errors.
11047 From Colin Smith (colin@wrs.com):
11048 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
11049 than install_operand.

11058 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
11060 * Makefile.in: defined TARGET_CPU for C code so that it can choose
11061 one element of a family.
11063 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
11065 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
11066 so that we can assemble hand-written libgcc code.
11068 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11070 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
11071 has already been formatted (but may still contain %-characters).
11072 (as_bad): Likewise.
11074 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
11076 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
11077 written with indirection on the last two operands, which can be
11078 either data or address registers. Added a new operand type 'r'
11079 which accepts either register type. Added '(' to notend stuff in
11080 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
11082 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
11084 * as.h (enum _relax_state): Start off at one, not zero, to better
11085 catch uninitialized-variable errors.
11086 (linkrelax): Declare new variable.
11088 * messages.c (warning_count, error_count): Default initializer is
11091 * write.c: Merged some declarations, using PARMS macro.

11093 data_last_frag): No longer static.
11094 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
11095 defined, call it. Change segments before calling fixup_segment.
11096 (relax_align): If linkrelax, provide extra padding.
11098 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
11099 their not having symbols associated.
11101 * tc-i960.c (norelax, instrument_branches): Default initializer is
11103 (linkrelax): Delete variable definition.

11126 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
11127 being used with args swapped, causing occasional lossage when
11128 refilling buffers after an include file.
11130 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
11132 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
11133 version. Discard bogus DONTDEF version.
11134 (as_warn, as_bad, as_fatal): Likewise.

11331 * Makefile.in (install): Install into $(tooldir)/bin, since that's
11332 where gcc looks for it.
11334 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
11336 * Makefile.in: Changed some lines to be less confusing for some

11376 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
11378 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

11402 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
11404 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
11406 * expr.c (operand): if can't work out what sort of operand it is,
11407 then look through FLT_CHARS for a hint.
11409 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
11411 * Makefile.in, configure.in: removed traces of namesubdir,
11412 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11413 copyrights to '92, changed some from Cygnus to FSF.
11415 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
11416 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11417 copyrights to '92, changed some from Cygnus to FSF.
11419 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11421 * expr.c: If an expression is single comma, then return with
11422 SEG_ABSENT rather than an error - since the sparc front end does
11423 really strange things with things like fbge,a
11425 * as.h: include bfd.h if using many sections
11426 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
11427 local labels didn't work.
11428 * listing.c (list_symbol_table): don't core dump when there's no
11430 * write.c, write.h: call fix_new with the right number of args on
11432 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
11435 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11437 * app.c: MRI compatibility - allow single quote to start a string.
11438 * as.c: fix typo recently introduced.
11439 * as.h : Don't include aout/reloc.h - it's not right for COFF!
11440 * expr.c: Much rewriting, to accomodate MRI syntax for
11441 expressions. Also easier to read now.
11442 * listing.c: Put back defuns
11443 * read.c: modified to accept MRI syntax, put back listing pseudo
11444 ops so that an assembler built with NO_LISTING ignores list ops
11446 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
11447 machine is a SPARC or a 29K.
11448 * config/obj-aout.c: added s_sect pseudo op
11449 * config/obj-coffbfd.c: lints, set the filehdr flags right and
11450 fill in the timestamp.
11451 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
11452 anymore, define all the relocs which the tc-<x> bit will use so we
11453 can translate from them to the coff types.
11454 * config/tc-a29k.c: reloc_type isn't ane enum any more
11455 * config/tc-m68k.c: Added NO_RELOC definition.
11457 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
11459 * Makefile.in: put header files before C source for TAGS; remove
11460 references to non-existent syscalls.h.
11462 * read.c, write.c subsegs.c: back out the .bss changes.
11464 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
11466 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
11468 * a.out.h: removed.
11470 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
11472 * symbols.c (local_label_name): symbols now start with ^A.
11474 * read.c, subsegs.c, write.c obj-coff.c: added handling of
11475 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
11476 generate these sections. .align: will use NOP_OPCODE or 0
11477 for padding. This is just for being nice to the
11480 * expr.c (operand): changed to generate local label "\001L0"
11481 starting with a ^A so that it is recognized as a local label.
11483 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
11485 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
11486 i/o opcodes - inb, inw, outb and outw. string manipulation with
11487 att syntax - scmp, slod, smov, ssca, ssto.
11489 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
11490 to just after .file .
11492 In obj_crawl_symbol_chain() where it tries to put the external
11493 symbols apart, with the condition:
11494 (!S_IS_DEFINED(symbolP) &&
11495 !S_IS_DEBUG(symbolP) &&
11496 !SF_GET_STATICS(symbolP))
11497 it was moving too many symbols out. So I switch it back to the
11499 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
11501 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
11502 so that we don't use the F_RELFLG which make the linker complain
11503 that somebody has stripped the relocation info.
11505 Also, the AIX ld program require that the relocation table
11506 is sorted by r_vaddr like the standard ATT assembler does.
11508 [he also changed the sizeof(struct ...)'s into the coff
11509 style FOOSZ macros. I'm not sure this is right, but I can't
11510 remember why. xoxorich.]
11512 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
11514 * Makefile.in, configure.in, doc: use the doc. Build it, install
11517 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
11519 * read.c: white space and comments only.
11521 * configure.in: use the new atof-ns32.c for ns32k.
11523 * write.c: comment change only.
11525 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
11526 aren't yet integrated.
11528 * tc-i860.[hc]: blew off the dust. Something must still be done
11529 about conflicting relocation types.
11531 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
11534 * tc-i960.c, tc-sparc.c: white space and comments only.
11536 * tc-a29k.h: delete duplicate macro definition.
11538 * new file atof-ns32k.c copied from hack's last unreleased gas.
11540 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
11542 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
11545 * nearly everything. flush ChangeLog, package as gas-1.92.1.
11546 ChangeLog's prior to this are sketchy at best. I have logs.
11547 They just aren't ChangeLogs.
