2881 reloc's addend field to zero for function symbols.
2882 (md_apply_fix): Simplify. For fixups which will require a SOM
2883 reloc, just clear out the necessary bits in the output file.

2903 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
2904 it's better to use the one in libiberty.
2906 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2908 * symbols.c (resolve_symbol_value, case O_symbol): Undo last

2946 * Makefile.in (comparison): When comparing as.new or gasp.new, try
2947 running the binary through sed to avoid differences due to

2962 (obj_elf_size): Deleted unused code. If size is non-reducible
2963 expression, allocate some storage for the sy_obj field and copy

2966 ecoff_frob_symbol if appropriate.
2968 * write.c (fixup_segment): For i386 elf and coff (for now), don't
2969 add in value of symbol from another defined section of the file.

3074 * configure.in: Set bfd_gas for all sparc targets in one place,
3075 instead of separately for each. Correctly handle user-supplied
3076 "--enable-bfd-gas" option.
3078 * gdbinit.in: Move "break abort" to end, in case gdb complains.
3080 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:

3088 (indent_level): No longer static.
3089 (print_symbol_value_1): Don't print frag address if it matches

3093 (print_expr_1): Fix whitespace before printing X_add_number.
3095 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
3096 not symbol_new, for symbols holding expression values.

3098 * write.c (fix_new_exp): Handle O_add by creating an
3099 expression-valued symbol, and calling fix_new_exp recursively.
3100 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
3101 undefined symbol and a constant, fold the constant into the fixup,
3102 and refer to the undefined symbol directly. Then process the
3103 fixup again from scratch.
3104 (write_object_file): Before calling adjust_reloc_syms, make a pass
3105 through the symbol list trying to resolve values.
3107 * write.c (print_fixup): New routine, for debugging.
3108 (write_relocs): Call bfd_install_relocation. Deleted various

3126 * write.c (write_relocs): Add file name and line number to
3127 as_fatal calls. Handle bfd_reloc_overflow case specifically when
3128 RELOC_EXPANSION_POSSIBLE.
3130 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3132 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
3133 here. Use them for deciding which PRINTF*LIKE macro definitions

3136 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
3137 default definitions matching what we were doing before.
3138 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
3139 always use the varargs form if not using stdarg. It's safe to
3140 always use vfprintf, because libiberty will provide it if the
3141 native system doesn't. Also, always make format be const.
3142 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

3160 false (if defined) as well as checking for reg_section.
3161 (listing_listing): Iterate fetching lines while line number is too
3162 low, and we haven't run off the end of the input file.
3164 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
3166 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

3189 md_estimate_size_before_relax, md_ri_to_chars,
3190 md_create_short_jump, md_create_long_jump.
3191 (brtab_emit): Use data_section, not SEG_DATA.
3193 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3195 * config/vms-conf.h: new file, manually derived from conf.in.

3209 * config/tc-mips.c (insns_since_cache_access): Remove.
3210 (append_insn): Remove setting of insns_since_cache_access, and

3213 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3215 * config/tc-mips.c (md_shortopts): Remove E.
3216 (md_longopts): Add EB and EL.
3217 (md_parse_option): Handle -EB and -EL as separate options, rather

3227 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
3229 * configure.in: Test for remove, not delete. Fix cross-assembler

3245 representation (only enum bitfields can avoid being bitstrings).
3246 (bitfield_suffix, setup_basic_type): new routines.
3247 (VMS_typedef_parse): use them. Now recognize bitfields of all
3248 integral types, not just type `int'. Caveat: the representation
3249 used for bitfields still does not work for objects placed in
3250 registers, and gcc's optimizer sometimes puts small structs there.
3252 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3254 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
3255 bit from const_flag.
3256 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.

3261 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
3262 (vms_check_for_special_label): new routine (tc_frob_label).
3263 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
3264 and `gcc2_compiled.' labels; they won't reach here any more.
3265 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
3266 double', use `vax_g_doubles' flag to select type of double.
3267 (VMS_write_object_file) [traceback setup]: don't pass symbols
3268 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin

3274 S_GET_VALUE() to avoid many repeated function calls.
3275 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
3276 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
3277 gets requested. [All the HACK_DEC_C_STARTUP code appears to
3278 be obsolete; gcc does it automatically for vms target. It's
3279 also misnamed, because it is for the "VAX C" run-time library,
3280 not the newer "DEC C" one which has much different startup code.]
3281 {various}: use `S_SET_xxx(symbol,new_value)' rather than
3282 `S_GET_xxx(symbol) = new_value'.

3307 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
3308 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
3309 pointer to 32 bits of unwind info.
3310 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
3311 pointer to the dummy symbol; set the addend field to fx_addnumber.

3534 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
3535 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
3536 message to try to ease confusion about autoconf's

4285 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
4286 to put a common symbol in a set.

4331 * read.c (emit_expr): Use memset to zero out memory, rather than
4332 going through md_number_to_chars. This permits handling symbolic

4385 m68040_control_regs, m68060_control_regs): New arrays.
4386 (control_regs): New pointer.
4387 (m68k_ip): Use control_regs instead of testing CPU every time.
4388 Use last_movec_reg too. In error messages, handle 68060, and
4389 print 68060 for mfloat, too.
4390 (m68k_init_after_args): Handle "68060". Use m68040up for making
4391 m68851 choice. Set control_regs.

4760 * config/tc-mips.c (append_insn): Permit branches to be switched
4761 with the preceding instruction even if .set nobopt has been seen.
4762 .set nobopt actually controls whether to bring up an instruction
4763 from the branch target, which gas does not currently support.

4903 elf_tc_make_sections stuff. It was there to support PA braindamage
4904 which has been fixed, and in the case of elf_tc_make_sections is
4905 redundant with elf_tc_final_processing.
4907 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4925 don't spew remainder of input file in error message.
4926 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error

4987 to make it pcrel_offset.
4988 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to

5008 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

5041 -non_shared to use NO_PIC (this is how the Irix 5 assembler
5042 works). Do not permit -G with SVR4_PIC.
5043 (s_abicalls): Warn if -G was used, and force -G 0.
5044 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for

5102 (set_symtab): New function, broken out from write_object_file.
5103 Counts symbol table instead of relying on an earlier count.
5104 (write_object_file): Call set_symtab, but do it after potentially
5105 invoking the *_frob_file macros. Don't bother counting symbols.
5106 Call symbol_remove, instead of expanding it in place. Moved the
5107 conditionalized `object_file_size' declaration down to
5108 conditionalized block where it's used. When using the absolute
5109 symbol for a fixup without a symbol, set sy_used_in_reloc.
5110 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
5111 the correct symbol for the absolute section.
5113 * subsegs.c (section_symbol): Use symbol_new instead of
5114 symbol_make, since we may want it to go into the symbol table.
5115 Make the new symbol have internal linkage. If

5117 symbol with the newly created GAS symbol.

5127 (sparc_ip, label "immediate"): Reject constants for pcrel
5128 instructions only if the relocation type indicates a "call"
5129 instruction and the offset is within range of a "jmpl %g0". If
5130 it's not in range, use the absolute section symbol plus an offset.
5131 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
5133 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
5135 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
5138 * configure.in: Eliminated all targets using obj-coff but not
5139 defining BFD_ASSEMBLER; I think all such targets that are
5140 supported will be matched by real CPU-OS combinations earlier in
5142 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
5143 some comments about the dpx2 configuration, but left it disabled,
5144 since it couldn't be reached before.

5159 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
5160 is not SEG_UNKNOWN rather than checking whether it is >= 0.

5163 it instead of global insn_label.
5164 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
5165 call to mips_emit_delay and pass it to mips_align.

5187 values to reduce number of lookups with S_GET_VALUE. Skip debug
5188 symbols to avoid "a really nasty bug". (From Holger Teutsch,
5189 holger@botbso.rhein-main.de.)
5190 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
5191 field. (Also from Holger Teutsch.) Watch for a would-be register
5192 mask that spans frags.
5194 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
5195 this_base, not line_base. (Patch from Andreas Arens,

7334 still being worked on. Mark Elf configurations (except sparc and
7335 i386) as developmental. Deleted cases matching some generic names
7336 in favor of more specific names. (E.g., when we get Alpha

7362 into a few places. Make all functions and variables which
7363 are only used within tc-hppa.c static. PARAMize all functions.
7364 Add comments to functions. Delete unused functions, variables,
7365 #defines, etc. Delete unused members within structures. Delete
7366 ldil;ble hacks -- it is believed they were installed to work
7367 around old gas bugs. Avoid using mixed case for local
7368 functions, variables, and structures. Fix formatting problems
7369 not found by GNU-indent. Add FIXME notices for things which
7370 should be worked on the near future. Delete lots of old

8533 * Extensive changes to permit symbols to contain any expression
8534 type and to delay the computation of the expression until the
8535 value is actually needed. This permits setting symbols to values
8536 calculated based on object code size. Expressions were changed to
8537 no longer be in a section, to stop the overloading of segment and
8538 expression type that previously occurred.
8540 * as.c (big_section, pass1_section, diff_section, absent_section):
8542 (expr_section): Added (used for dummy symbols which hold

8626 (previous_section, previous_subsection): New vars.
8627 (obj_elf_section): Save current place in case DWARF code wants us
8628 to pop back to it. Handle unquoted section name as well as quoted
8629 section name. Don't crash on invalid strings.
8630 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

8742 sy_resolved and sy_resolving single bit fields.
8743 * symbols.c (symbol_new): Don't initialize sy_forward field.

9777 than ECOFF line number information.
9778 (obj_ecoff_stab): Accept non-zero values for stabs line number.

9810 * doc/as.texinfo: First pass at using new texinfo features --
9811 variables, conditional tests. Far from complete.

9839 dependencies are read, not when they are used).
9841 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
9842 a29k .bss section; the mondfe program doesn't like it.

9857 (srcdir): Delete second, bogus definition.
9858 (as.info): Look for as-*.texinfo in current directory rather than
9862 * doc/configure.in: Create links to all as-*.texinfo files in the
9863 source directory, if that's not the current directory.
9865 * configure.in (per-host): Accept MIPS host with BSD version

9886 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
9887 process relocs if there aren't any relocs to process. Avoids
9888 malloc/free bug on SCO too.

9891 avoid some redefinition complaints on some systems.
9892 (const, volatile): Don't need these conditionally defined if we
9893 use CONST and VOLATILE from ansidecl.h.
9894 (seg_name): Use CONST, not const.
9896 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
9898 * config/tc-mips.c: Reindented to GNU standards.
9900 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
9902 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
9903 (fixup_segment): Add a29k special case; the linker is not prepared
9904 to see a segment offset here.
9906 * app.c (do_scrub_next_char): Added new state, 10, modifying state
9907 9 to only keep a space in between identifier characters.
9909 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
9911 * Makefile.in: add dvi target; as-$(config).texinfo might live in
9912 srcdir, might be in objdir.
9914 * doc/Makefile.in: dvi depends on as.dvi

9937 * Makefile.in (targ-cpu.o): Depend on config.h.
9939 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
9941 * app.c (do_scrub_next_char): Added new state, 9, to avoid
9942 dropping a space immediately following an identifier.
9943 * expr.c, write.c: Rewrote assert expressions to not use multiple
9944 lines; I don't think that can be done portably.
9945 * config/tc-mips.c (macro): Use $AT if target register is zero in
9946 load instruction, which it can be for a floating point load.
9948 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

9956 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
9959 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
9960 z8k-opc.h, not z8k.h.
9962 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
9965 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9967 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
9969 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)

10020 prototypes for all static functions. Moved existing minimal
10021 debugging format support info #ifndef OBJ_ECOFF blocks.
10022 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
10023 does not support a non sign extended high 16 bits reloc. Adjusted

10070 * make-gas.com: Find obstack.obj if it's not in the current
10072 * read.c (s_ignore): Don't declare is_end_of_line. It's
10073 redundant, and triggers a VMS gcc compiler bug.
10075 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
10076 current segment as an argument. (Ignored in all cases but VMS.)
10077 All callers and definitions changed.
10079 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
10081 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING

10093 (obj_elf_xstab): New routine.
10094 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
10095 argument to s_ignore. Put "#if 0" around unused code.
10096 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
10097 Call elf_xstabs for .stabs and .xstabs operators.
10099 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
10101 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
10104 * configure.in: mips-bsd configuration was missing format spec.
10107 * Makefile.in (Makefile): Depends on configure.in.
10109 * config/tc-mips.c (append_insn): Don't check for alignment of
10110 frag in memory; alignment of instructions in section is a separate

10130 * config/tc-sparc.c (s_xword): Now call big_cons, so large
10131 constants are accepted, but symbolic values are not. GCC will not
10132 generate the latter currently.
10134 * frags.c (frag_init): New function.
10135 (zero_address_frag, bss_address_frag): Now initialized at run

10169 referencing symbol structure members.
10170 (obj_aout_frob_symbol) [BFD_ASSEMBLER]: New function.
10172 * as.h (struct frag): Reordered a couple of fields for better

10178 (write_object_file) [BFD_ASSEMBLER]: Always handle -R here. Call
10179 fix_new with BFD_RELOC_NONE instead of 0 or NO_RELOC. Call
10180 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
10181 (fixup_segment): Make sure common-section symbols get treated the
10182 same as undefined symbols.
10183 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type

10186 * write.h (fix_new): Update prototype.
10188 * tc.h (md_operand, md_convert_frag, tc_headers_hook,
10189 md_section_align, md_undefined_symbol): Don't provide prototypes
10190 if these are defined as macros.
10191 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and

10210 (subseg_new) [BFD_ASSEMBLER]: Rewritten to change to new section,
10211 given section name and subseg number.
10212 (subseg_set) [BFD_ASSEMBLER]: New function; change to a possibly
10213 new section/subsection.
10215 * read.c: Don't include ctype.h.
10216 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
10217 for now; should be machine-dependent.
10219 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
10220 targets, forcing BFD use.
10222 Wed Feb 17 18:59:03 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
10224 * config/tc-sparc.c: Use PARAMS macro for static function
10225 declarations. Use BFD_RELOC_ macros everywhere, with
10226 compatibility macros declared for non-BFD mode.
10227 (struct sparc_it) [BFD_ASSEMBLER]: Use bfd_reloc_code_real_type
10228 instead of enum reloc_type.

10387 * config/tc-sparc.c (architecture_requested, warn_on_bump,
10388 md_relax_table): Use default zero initialization.
10389 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

10402 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
10404 * expr.c (operand): If character other than comma or newline is a
10405 logical end-of-line character, use the newline case.
10406 From Eric Youngdale:
10407 (operand): Set X_add_number field for floating-point numbers.
10408 (operand): Treat zero byte as end-of-operand.
10410 * configure.in (per-target): Look for with_bfd_assembler option.
10411 For now, only accept "no", until the merge is done.
10413 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
10414 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
10415 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
10416 * read.c: Finish conversion to S_* macros in the VMS only
10417 parts of the program. Add "const" modifier to hex_value.
10418 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
10420 * expr.c: Add "const" modifier to hex_value.
10421 * symbols.c: Finish conversion to S_* macros in the VMS only
10422 parts of the program. Add "const" modifier to
10423 md_[long,short]_jump_size. Remove declaration of const_flag
10424 (which will be declared in obj-vms.h).
10425 * write.c: Add "const" modifier to md_[long,short]_jump_size.
10426 Fix arguments to VMS_write_object_file.
10427 * config-gas.com: New file. Script for VMS systems to set up the
10428 configuration to build gas for VMS, and create config.status.
10429 * make-gas.com: Redone to work with new scheme.
10430 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
10432 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
10433 will swap bytes if needed on a big endian system. Use throughout
10435 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
10436 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
10437 types of malformed stabs. Change parsing algorithm so that we are
10438 more certain of having all of the information that we need on hand.
10439 * obj-vms.c (final_forward_reference): New function, used to help
10440 resolve the data types of as many struct elements as possible
10441 when some part of the struct is not fully defined by the compiler.
10442 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
10444 * obj-vms.c (VMS_write_object_file): Define all vtable psects
10445 as symbols as well in the object file. Look for external functions

10455 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
10457 * read.c (s_data): Always use "data_section", since it'll map to
10458 SEG_DATA or SEG_E1 if needed.
10459 (s_lcomm): Likewise with bss_section.
10460 (s_fill): Use memset, not bzero.
10462 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10464 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

10481 otherwise, use seg_name array.
10482 (seg_name): Declare only if not BFD_ASSEMBLER.
10483 (section_alignment): Declare only if not BFD_ASSEMBLER.
10484 (big_section, reg_section, pass1_section, diff_section,
10485 absent_section, text_section, data_section, bss_section): If
10486 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
10487 mapping to segT enum values.
10488 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
10489 if these are used or defined, if BFD_ASSEMBLER.
10490 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
10491 subseg_new split into two functions.
10492 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
10494 * as.h (volatile): Don't define if already defined.

10506 <mtranle@paris.intellicorp.com>.
10507 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
10508 obj_format coffbfd and gas_target i386coff for target.
10509 (i[34]86-*-isc*): New host (uses sysv).
10510 * config/i386aix.mt: Removed (no longer used).
10511 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
10512 (MINUS_G): Removed.
10513 (LDFLAGS): Added, defined as -shlib.
10514 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
10515 * config/te-sco386.h (LOCAL_LABEL): Don't define.
10516 (DOT_LABEL_PREFIX): Define.
10517 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
10518 name rather than L0\001.

10521 * symbols.c, symbols.h (local_bss_counter): Removed.
10522 * write.c (write_object_file): bss no longer uses
10523 local_bss_counter. Pass correct data and bss size to
10524 VMS_write_object_file.
10525 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
10526 argument, rather than using local_bss_counter.

10530 (size_section): Restored sanity check.
10531 (do_relocs_for): Base section address on s_paddr rather than
10532 computing it. Adjust a29k R_IHIHALF special case to account for
10533 section paddr (used to require paddr to be zero). If there are no
10534 reclos, set s_relptr to 0. Set relocation size in object_headers.
10535 (fill_section): Always set s_vaddr here, removing
10536 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
10537 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
10538 Set STYP_INFO for .comment.
10539 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
10540 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

10543 (do_linenos_for): Set lineno size in object_headers.
10544 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
10545 set s_vaddr here. If string_byte_count remains 4, set it back to
10546 0, and only write strings out if there are some. Call
10547 fill_section before do_relocs_for and do_linenos_for.
10548 (obj_coff_section): Handle optional quoted second argument giving
10549 section characteristics.
10550 (obj_coff_bss): Added to handle .bss.
10551 (obj_coff_ident): Added to handle .ident (puts string in .comment

10571 (do_scrub_next_char): For \", return " not '.
10572 (symbol_chars): Now const.
10574 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
10575 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
10577 * config/obj-coff.h: Don't use #elif.
10579 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
10580 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
10582 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
10584 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

10602 * Changes to support SCO 3.2v4:
10603 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
10604 SEG_BSS, fill with NOP_OPCODE.
10605 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
10606 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
10607 using ZERO_BASED_SEGMENTS.
10608 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
10609 never set segment address for SEG_E2 (.bss) and don't write out
10610 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
10611 (obj_coff_endef): Don't merge labels or symbols awaiting forward
10612 definitions, and don't merge tags with non-tags. Check for .bf
10613 rather than just checking whether the second character is b and
10614 the third character is f.
10615 (obj_coff_val): gcc can generate values which we don't handle
10616 correctly; discard information for now, since it only affects the
10617 debugging information.
10618 (tag_find_or_name): Don't insert tags in the symbol table.
10619 (yank_symbols): Don't merge labels.
10620 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

10626 relative addends by the segment vaddr.
10627 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
10628 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

10770 z8000 documentation
10771 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
10774 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
10776 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
10778 * subsegs.h: add extern to segment_info declaration.
10780 * read.h: added extern declarations for comment_chars,
10781 line_comment_chars, and line_separator_chars.
10782 read.c, app.c: removed definitions of comment_chars,
10783 line_comment_chars, and line_separator_chars.

10802 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
10803 constant will not fit in an immediate field.

10808 * obj-coff.c (callj_table): Delete global variable.
10809 (obj_emit_relocations): Define it locally here, and only if
10810 TC_I960 is defined.
10812 * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.

10841 * Support for i386-sysv.
10842 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
10843 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
10844 be used to set them all to zero as was done before.
10845 (fill_section): segment addresses now set in write_object_file.
10846 (fill_section): Don't set STYP_NOLOAD for .bss section.
10847 (fixup_segment): 386 uses strange common symbol format.

10882 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
10884 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
10885 #elif, since it is not supported by old compilers.
10886 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
10887 couple of expressions in tc-m68k.c.
10889 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10891 * read.c (cons): If NO_RELOC is defined, use it.

10897 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
10898 local labels to start with a .) and set REGISTER_PREFIX to %.
10899 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
10901 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
10903 * messages.c: Comment changes.
10905 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

10908 * messages.c: If __STDC__ is not defined, define NO_STDARG.
10910 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
10912 * listing.c (debugging_pseudo): Add stabs and stabn as things to
10915 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
10917 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
10918 sections starting from zero, rather than making them consecutive.
10919 This makes subsequent reloc calculations easier, esp if the object
10920 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
10921 allocate lcomm in .data rather than in .bss. It seems that some
10922 tools can't cope with a non-zero sized bss before linkage.
10924 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10926 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10927 throughout. That enum no longer means what we thought it meant.
10929 * tc-m68k.c (md_assemble, md_parse_option): Handle new
10930 "-mno-688[58]1" options.
10932 * tc-m68k.c: Added CPU32 support.
10934 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

10945 * Makefile.in (install): if $(tooldir) exists, install as in
10948 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10950 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10951 .word is < -32768 or > 32767. The -J flag causes the error to be
10952 ignored. This is to catch over-sized switches generated by gcc on
10953 systems which don't support the broken .word hack.
10954 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10955 write.c (fixup_segment): check for signed .word overflow if
10956 WARN_SIGNED_OVERFLOW_WORD.
10958 * write.c (fixup_segment): fixed missing parens in expression
10959 checking for byte or word overflow.
10961 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
10962 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
10963 WARN_SIGNED_OVERFLOW_WORD.

10975 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
10977 * input-scrub.c (input_scrub_push): call input_file_begin, not
10979 messages.c (as_perror): print ": " between the passed in error and
10980 the strerror, like perror does.
10982 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

10989 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
10990 Motorola and MIT syntax; gas can now assemble either type of
10992 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
10993 From Steve Chamberlain:
10994 m68kcoff.mt: for m68k COFF.
10995 obj-coffbfd.c: (fixup_mdeps) added
10996 (size_section) removed bad sanity check
10997 (fill_section) added rs_machine_dependent case
10998 (write_object_file) call fixup_mdeps
10999 (fixup_segment) set fx_subsy to 0.
11000 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
11002 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
11005 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

11029 tc-i960.c (md_ri_to_chars): Always output bout object file in
11030 little endian byte order (used to use endianness of host).
11032 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11034 * config/tc-m68k.c (init_table): Now const. Always include 68851
11035 data, so that "bc" is available to 68040 cache instructions.
11036 Added "tt0", "tt1", and 68ec030 variants.
11037 (md_assemble): Complain if 68000 (only) and 68881 are specified.
11038 (enum _register): Added TT0, TT1.
11039 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
11040 line number correctly in "internal error" messages. Don't print
11041 architecture-mismatch message for operand errors.
11043 From Colin Smith (colin@wrs.com):
11044 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
11045 than install_operand.
11047 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)

11054 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
11056 * Makefile.in: defined TARGET_CPU for C code so that it can choose
11057 one element of a family.
11059 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
11061 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
11062 so that we can assemble hand-written libgcc code.
11064 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11066 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
11067 has already been formatted (but may still contain %-characters).
11068 (as_bad): Likewise.
11070 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
11072 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
11073 written with indirection on the last two operands, which can be
11074 either data or address registers. Added a new operand type 'r'
11075 which accepts either register type. Added '(' to notend stuff in
11076 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
11078 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
11080 * as.h (enum _relax_state): Start off at one, not zero, to better
11081 catch uninitialized-variable errors.
11082 (linkrelax): Declare new variable.
11084 * messages.c (warning_count, error_count): Default initializer is
11087 * write.c: Merged some declarations, using PARMS macro.

11089 data_last_frag): No longer static.
11090 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
11091 defined, call it. Change segments before calling fixup_segment.
11092 (relax_align): If linkrelax, provide extra padding.
11094 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
11095 their not having symbols associated.
11097 * tc-i960.c (norelax, instrument_branches): Default initializer is
11099 (linkrelax): Delete variable definition.

11122 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
11123 being used with args swapped, causing occasional lossage when
11124 refilling buffers after an include file.
11126 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
11128 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
11129 version. Discard bogus DONTDEF version.
11130 (as_warn, as_bad, as_fatal): Likewise.
11132 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
11134 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
11135 selected architecture, print a message saying so and listing what
11136 processors support it, rather than saying "operands mismatch".
11138 Thu Aug 13 13:53:19 1992 Ken Raeburn (raeburn@cygnus.com)

11327 * Makefile.in (install): Install into $(tooldir)/bin, since that's
11328 where gcc looks for it.
11330 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
11332 * Makefile.in: Changed some lines to be less confusing for some

11372 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
11374 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

11398 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
11400 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
11402 * expr.c (operand): if can't work out what sort of operand it is,
11403 then look through FLT_CHARS for a hint.
11405 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
11407 * Makefile.in, configure.in: removed traces of namesubdir,
11408 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11409 copyrights to '92, changed some from Cygnus to FSF.
11411 * doc/Makefile.in, doc/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 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11417 * expr.c: If an expression is single comma, then return with
11418 SEG_ABSENT rather than an error - since the sparc front end does
11419 really strange things with things like fbge,a
11421 * as.h: include bfd.h if using many sections
11422 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
11423 local labels didn't work.
11424 * listing.c (list_symbol_table): don't core dump when there's no
11426 * write.c, write.h: call fix_new with the right number of args on
11428 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
11431 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11433 * app.c: MRI compatibility - allow single quote to start a string.
11434 * as.c: fix typo recently introduced.
11435 * as.h : Don't include aout/reloc.h - it's not right for COFF!
11436 * expr.c: Much rewriting, to accomodate MRI syntax for
11437 expressions. Also easier to read now.
11438 * listing.c: Put back defuns
11439 * read.c: modified to accept MRI syntax, put back listing pseudo
11440 ops so that an assembler built with NO_LISTING ignores list ops
11442 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
11443 machine is a SPARC or a 29K.
11444 * config/obj-aout.c: added s_sect pseudo op
11445 * config/obj-coffbfd.c: lints, set the filehdr flags right and
11446 fill in the timestamp.
11447 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
11448 anymore, define all the relocs which the tc-<x> bit will use so we
11449 can translate from them to the coff types.
11450 * config/tc-a29k.c: reloc_type isn't ane enum any more
11451 * config/tc-m68k.c: Added NO_RELOC definition.
11453 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
11455 * Makefile.in: put header files before C source for TAGS; remove
11456 references to non-existent syscalls.h.
11458 * read.c, write.c subsegs.c: back out the .bss changes.
11460 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
11462 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
11464 * a.out.h: removed.
11466 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
11468 * symbols.c (local_label_name): symbols now start with ^A.
11470 * read.c, subsegs.c, write.c obj-coff.c: added handling of
11471 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
11472 generate these sections. .align: will use NOP_OPCODE or 0
11473 for padding. This is just for being nice to the
11476 * expr.c (operand): changed to generate local label "\001L0"
11477 starting with a ^A so that it is recognized as a local label.
11479 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
11481 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
11482 i/o opcodes - inb, inw, outb and outw. string manipulation with
11483 att syntax - scmp, slod, smov, ssca, ssto.
11485 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
11486 to just after .file .
11488 In obj_crawl_symbol_chain() where it tries to put the external
11489 symbols apart, with the condition:
11490 (!S_IS_DEFINED(symbolP) &&
11491 !S_IS_DEBUG(symbolP) &&
11492 !SF_GET_STATICS(symbolP))
11493 it was moving too many symbols out. So I switch it back to the
11495 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
11497 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
11498 so that we don't use the F_RELFLG which make the linker complain
11499 that somebody has stripped the relocation info.
11501 Also, the AIX ld program require that the relocation table
11502 is sorted by r_vaddr like the standard ATT assembler does.
11504 [he also changed the sizeof(struct ...)'s into the coff
11505 style FOOSZ macros. I'm not sure this is right, but I can't
11506 remember why. xoxorich.]
11508 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
11510 * Makefile.in, configure.in, doc: use the doc. Build it, install
11513 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
11515 * read.c: white space and comments only.
11517 * configure.in: use the new atof-ns32.c for ns32k.
11519 * write.c: comment change only.
11521 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
11522 aren't yet integrated.
11524 * tc-i860.[hc]: blew off the dust. Something must still be done
11525 about conflicting relocation types.
11527 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
11530 * tc-i960.c, tc-sparc.c: white space and comments only.
11532 * tc-a29k.h: delete duplicate macro definition.
11534 * new file atof-ns32k.c copied from hack's last unreleased gas.
11536 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
11538 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
11541 * nearly everything. flush ChangeLog, package as gas-1.92.1.
11542 ChangeLog's prior to this are sketchy at best. I have logs.
11543 They just aren't ChangeLogs.
