308 * read.c (emit_expr): Use memset to zero out memory, rather than
309 going through md_number_to_chars. This permits handling symbolic
310 arguments when the size is larger than sizeof (valueT), if

363 (control_regs): New pointer.
364 (m68k_ip): Use control_regs instead of testing CPU every time.

691 (COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
693 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
694 can be used within a label name.
696 * config/tc-m68k.h (m68k_init_after_args): Declare.
697 (tc_init_after_args): Define as m68k_init_after_args.

720 * listing.c (list_symbol_table): Don't print register symbols as
723 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip

727 * as.c (main): If tc_init_after_args is defined, invoke it after
728 all arguments have been processed.

811 directory, and specify PSECT attributes explicitly to linker.
812 Also added missing label.

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

964 to make it pcrel_offset.
965 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
966 reloc->address; another gruesome hack to get gas reloc handling to
969 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
971 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
974 (emit_insn): New function.
975 (md_assemble): Call it.
976 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
978 (lituse_pending): New variable. Set by anything that generates a
979 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
980 tested by code that might want to emit a LITUSE reloc.
981 (emit_unaligned_io): New function. Currently calls md_assemble,
982 but it should eventually be converted to generate the insn itself
983 and call emit_insn directly.
984 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
985 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
986 emit_bis_r): Likewise.
987 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
988 (alpha_ip, label get_macro): Don't emit the final instruction if
990 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
991 unaligned memory access macros.
992 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
993 the value can't be resolved.
995 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
997 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
998 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
999 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
1001 (mips_force_relocation): New function.
1002 (md_apply_fix): Set fixP->fx_done appropriately.
1003 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

1011 * config/tc-mips.c (enum mips_pic_level): New enum.
1012 (mips_pic): Change from int to enum mips_pic_level. Change all
1013 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
1014 (load_address): Handle EMBEDDED_PIC.
1015 (macro): Handle EMBEDDED_PIC in all PIC cases.
1016 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
1017 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
1018 -non_shared to use NO_PIC (this is how the Irix 5 assembler
1019 works). Do not permit -G with SVR4_PIC.
1020 (s_abicalls): Warn if -G was used, and force -G 0.
1021 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
1022 anything but a.out, not just for ELF. For ECOFF, don't generate a
1023 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
1025 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
1027 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1029 * config/tc-hppa.c (create_new_space): Use ints, not chars as
1030 parameters to avoid losing when compiling with HP CC.
1031 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
1033 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1035 * Makefile.in (config-stamp): If `defs' is defined, emit a
1036 preprocessor directive to create a macro named by this value into
1037 config.new; don't explicitly go for BFD_ASSEMBLER.
1038 * configure.in: Define `defs', not `BFDDEF'. Set it to
1039 MANY_SEGMENTS for any obj-coffbfd target.
1040 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
1041 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
1043 (LOCAL_LOADLIBES): Deleted.
1044 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
1045 * config/m88kcoff.mt (TDEFINES): Ditto.
1046 * config/ebmon29k.mt: Deleted.
1047 * config/h8300hds.mt: Deleted.

1049 * config/sparc.mt: Deleted.
1050 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

1071 bfd_set_symtab is called.
1072 (dump_section_relocs): Note whether a symbol is a section symbol
1074 (adjust_reloc_syms): For now, always supply an absolute symbol for
1075 fixups without symbols but not yet `done'. Use section_symbol to
1076 get the symbol, instead of going directly for abs_symbol.
1077 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
1078 reloc is not a section symbol and is not in the symbol table.
1079 (set_symtab): New function, broken out from write_object_file.
1080 Counts symbol table instead of relying on an earlier count.
1081 (write_object_file): Call set_symtab, but do it after potentially
1082 invoking the *_frob_file macros. Don't bother counting symbols.
1083 Call symbol_remove, instead of expanding it in place. Moved the
1084 conditionalized `object_file_size' declaration down to
1085 conditionalized block where it's used. When using the absolute
1086 symbol for a fixup without a symbol, set sy_used_in_reloc.
1087 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
1088 the correct symbol for the absolute section.
1090 * subsegs.c (section_symbol): Use symbol_new instead of
1091 symbol_make, since we may want it to go into the symbol table.
1092 Make the new symbol have internal linkage. If
1093 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
1094 symbol with the newly created GAS symbol.
1095 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
1096 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

1101 (in_signed_range): New function.
1103 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
1104 (sparc_ip, label "immediate"): Reject constants for pcrel
1105 instructions only if the relocation type indicates a "call"
1106 instruction and the offset is within range of a "jmpl %g0". If
1107 it's not in range, use the absolute section symbol plus an offset.
1108 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
1110 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
1112 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
1115 * configure.in: Eliminated all targets using obj-coff but not
1116 defining BFD_ASSEMBLER; I think all such targets that are
1117 supported will be matched by real CPU-OS combinations earlier in
1119 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
1120 some comments about the dpx2 configuration, but left it disabled,
1121 since it couldn't be reached before.
1122 (target a29k-amd-ebmonold): Deleted.
1124 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

1132 the 'j' operand if there are no further alternatives for this
1135 * config/obj-coffbfd.c (adjust_stab_section): Initialize
1136 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
1137 is not SEG_UNKNOWN rather than checking whether it is >= 0.
1139 * config/tc-mips.c (mips_align): Take new argument, label, and use
1140 it instead of global insn_label.
1141 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
1142 call to mips_emit_delay and pass it to mips_align.
1144 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1146 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
1148 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
1149 argument to a .callinfo directive. Don't loop forever on errors.
1151 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
1152 use pre-defined registers as arguments.

1156 * write.c (write_object_file): Check both S_IS_LOCAL and
1157 S_IS_EXTERNAL when deciding whether to discard a symbol.
1159 * config-gas.com: Scan Makefile.in, not version.c, for current
1160 version number. Delete all versions of temp files when finished
1161 with them. Create config.h.
1163 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
1164 values to reduce number of lookups with S_GET_VALUE. Skip debug
1165 symbols to avoid "a really nasty bug". (From Holger Teutsch,
1166 holger@botbso.rhein-main.de.)
1167 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
1168 field. (Also from Holger Teutsch.) Watch for a would-be register
1169 mask that spans frags.
1171 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
1172 this_base, not line_base. (Patch from Andreas Arens,
1173 ari@obelix.av.rwth-aachen.de.)
1175 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
1176 look local if they're exported or undefined. Used to be done for
1179 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
1180 Get it from the looked-up symbol, instead of using the string from
1181 the input stream, which is no longer null-terminated.
1182 (LEX_PCT): New macro, defaults to 0.
1183 (lex_type): Use it for `%'.
1185 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

1235 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
1236 0xffff for 'j' to be compatible with MIPS assembler. These

3303 * config/tc-m68k.h: Don't define REGISTER_PREFIX or
3304 OPTIONAL_REGISTER_PREFIX if either is already defined.
3306 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
3308 * configure.in: Set bfd_gas for all sparc targets. Added facility
3309 for keeping or rejecting configurations still under development;
3310 default is to assume production environment, and reject configs
3311 still being worked on. Mark Elf configurations (except sparc and
3312 i386) as developmental. Deleted cases matching some generic names
3313 in favor of more specific names. (E.g., when we get Alpha
3314 support, we'll still only support VMS for Vax.)
3316 * config/tc-sparc.h (md_end): New macro.
3317 * config/tc-sparc.c (md_end): Function deleted.
3318 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

3328 against placing additional object-file dependent code here. Warn
3329 against contaminating all of GAS with the internals of tc-hppa.c
3330 through inclusion of tc-hppa.h. Delete all forward declarations
3331 for functions only used within tc-hppa.c, likewise for structures,
3332 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
3333 conditional code in a few small places.
3335 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3336 structures, global variables, forward declarations together.
3337 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
3338 conditional code -- try to group conditional code together
3339 into a few places. Make all functions and variables which
3340 are only used within tc-hppa.c static. PARAMize all functions.
3341 Add comments to functions. Delete unused functions, variables,
3342 #defines, etc. Delete unused members within structures. Delete
3343 ldil;ble hacks -- it is believed they were installed to work
3344 around old gas bugs. Avoid using mixed case for local
3345 functions, variables, and structures. Fix formatting problems
3346 not found by GNU-indent. Add FIXME notices for things which
3347 should be worked on the near future. Delete lots of old
3348 useless (1.36 PA-SOM) code.

3365 * config/tc-hppa.c: Likewise.
3367 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
3368 of elf32_symbol_type.
3369 (pa_export_args): Likewise.
3370 (elf_hppa_final_processing): Likewise.
3371 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

3376 * config/tc-hppa.c: (md_section_align): Align all sections to
3377 a multiple of the section alignment rather than always a
3380 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
3381 bits are zero (eg they specify no relocations), then do not even
3382 bother adding their entries to thesymextn section.

3423 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
3424 call strchr for each character to see if it is a special char,
3425 instead add a second loop over special_chars. Set alignment
3426 of text, data and bss sections to 4.
3427 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3429 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3430 ELF, since the ELF object format does not have these type of
3431 relocations. Change the abort into as as_bad and return
3432 BFD_RELOC_NONE to silence compiler warnings.
3433 (md_assemble): Keep track of the instruction size. Allow white
3434 space between the $ and the constant for compatibility with older
3435 gases and other assemblers.

5819 a29k .bss section; the mondfe program doesn't like it.

5840 source directory, if that's not the current directory.
5842 * configure.in (per-host): Accept MIPS host with BSD version

5868 avoid some redefinition complaints on some systems.
5869 (const, volatile): Don't need these conditionally defined if we
5870 use CONST and VOLATILE from ansidecl.h.
5871 (seg_name): Use CONST, not const.

5875 * config/tc-mips.c: Reindented to GNU standards.
5877 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
5879 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5880 (fixup_segment): Add a29k special case; the linker is not prepared
5881 to see a segment offset here.
5883 * app.c (do_scrub_next_char): Added new state, 10, modifying state
5884 9 to only keep a space in between identifier characters.
5886 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5888 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5889 srcdir, might be in objdir.

5919 dropping a space immediately following an identifier.
5920 * expr.c, write.c: Rewrote assert expressions to not use multiple
5921 lines; I don't think that can be done portably.
5922 * config/tc-mips.c (macro): Use $AT if target register is zero in
5923 load instruction, which it can be for a floating point load.

5936 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
5937 z8k-opc.h, not z8k.h.
5939 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
5942 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

5997 prototypes for all static functions. Moved existing minimal
5998 debugging format support info #ifndef OBJ_ECOFF blocks.

6047 * make-gas.com: Find obstack.obj if it's not in the current
6049 * read.c (s_ignore): Don't declare is_end_of_line. It's
6050 redundant, and triggers a VMS gcc compiler bug.
6052 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
6053 current segment as an argument. (Ignored in all cases but VMS.)
6054 All callers and definitions changed.

6072 argument to s_ignore. Put "#if 0" around unused code.
6073 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
6074 Call elf_xstabs for .stabs and .xstabs operators.
6076 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
6078 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
6081 * configure.in: mips-bsd configuration was missing format spec.
6084 * Makefile.in (Makefile): Depends on configure.in.

6192 * read.c: Don't include ctype.h.
6193 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
6194 for now; should be machine-dependent.
6196 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
6197 targets, forcing BFD use.

6381 * expr.c (operand): If character other than comma or newline is a
6382 logical end-of-line character, use the newline case.

6384 (operand): Set X_add_number field for floating-point numbers.
6385 (operand): Treat zero byte as end-of-operand.
6387 * configure.in (per-target): Look for with_bfd_assembler option.
6388 For now, only accept "no", until the merge is done.
6390 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
6391 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

6397 * expr.c: Add "const" modifier to hex_value.
6398 * symbols.c: Finish conversion to S_* macros in the VMS only
6399 parts of the program. Add "const" modifier to
6400 md_[long,short]_jump_size. Remove declaration of const_flag
6401 (which will be declared in obj-vms.h).
6402 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6403 Fix arguments to VMS_write_object_file.
6404 * config-gas.com: New file. Script for VMS systems to set up the
6405 configuration to build gas for VMS, and create config.status.
6406 * make-gas.com: Redone to work with new scheme.
6407 * obj-vms.c: Patch to fix bug where we were not correctly parsing the

6412 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
6413 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6414 types of malformed stabs. Change parsing algorithm so that we are
6415 more certain of having all of the information that we need on hand.
6416 * obj-vms.c (final_forward_reference): New function, used to help
6417 resolve the data types of as many struct elements as possible

6421 * obj-vms.c (VMS_write_object_file): Define all vtable psects
6422 as symbols as well in the object file. Look for external functions

6425 * tc-vax.c: Add '1' option for backward compatibility with older GCC
6427 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

6435 SEG_DATA or SEG_E1 if needed.
6436 (s_lcomm): Likewise with bss_section.
6437 (s_fill): Use memset, not bzero.

6464 mapping to segT enum values.
6465 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
6466 if these are used or defined, if BFD_ASSEMBLER.
6467 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6468 subseg_new split into two functions.
6469 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6471 * as.h (volatile): Don't define if already defined.
6472 (had_errors, had_warnings): Provide prototypes for ANSI C even if
6474 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
6475 declare with format attribute for -Wformat checking.
6477 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
6479 * app.c, config/tc-*.c: Don't include read.h, since it is already

6492 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6493 (DOT_LABEL_PREFIX): Define.

6495 name rather than L0\001.
6496 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
6498 * symbols.c, symbols.h (local_bss_counter): Removed.
6499 * write.c (write_object_file): bss no longer uses
6500 local_bss_counter. Pass correct data and bss size to
6501 VMS_write_object_file.

6507 (size_section): Restored sanity check.
6508 (do_relocs_for): Base section address on s_paddr rather than
6509 computing it. Adjust a29k R_IHIHALF special case to account for

6511 reclos, set s_relptr to 0. Set relocation size in object_headers.
6512 (fill_section): Always set s_vaddr here, removing
6513 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6514 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6515 Set STYP_INFO for .comment.
6516 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
6517 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

6519 H_{SET,GET}_* macros.
6520 (do_linenos_for): Set lineno size in object_headers.
6521 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6522 set s_vaddr here. If string_byte_count remains 4, set it back to
6523 0, and only write strings out if there are some. Call
6524 fill_section before do_relocs_for and do_linenos_for.
6525 (obj_coff_section): Handle optional quoted second argument giving
6526 section characteristics.
6527 (obj_coff_bss): Added to handle .bss.
6528 (obj_coff_ident): Added to handle .ident (puts string in .comment

6548 (do_scrub_next_char): For \", return " not '.
6549 (symbol_chars): Now const.
6551 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6552 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6554 * config/obj-coff.h: Don't use #elif.
6556 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't

6587 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6588 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6589 definitions, and don't merge tags with non-tags. Check for .bf
6590 rather than just checking whether the second character is b and
6591 the third character is f.
6592 (obj_coff_val): gcc can generate values which we don't handle

6596 (yank_symbols): Don't merge labels.
6597 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6743 could be doing emulation.
6745 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6748 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
6751 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)

6777 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6779 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6780 constant will not fit in an immediate field.
6781 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

6818 * Support for i386-sysv.
6819 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6859 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6861 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6862 #elif, since it is not supported by old compilers.
6863 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6864 couple of expressions in tc-m68k.c.
6866 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6868 * read.c (cons): If NO_RELOC is defined, use it.
6870 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.

6892 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6894 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6895 sections starting from zero, rather than making them consecutive.
6896 This makes subsequent reloc calculations easier, esp if the object
6897 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6898 allocate lcomm in .data rather than in .bss. It seems that some
6899 tools can't cope with a non-zero sized bss before linkage.
6901 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6903 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6904 throughout. That enum no longer means what we thought it meant.

6907 "-mno-688[58]1" options.
6909 * tc-m68k.c: Added CPU32 support.

6922 * Makefile.in (install): if $(tooldir) exists, install as in
6925 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6927 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6928 .word is < -32768 or > 32767. The -J flag causes the error to be
6929 ignored. This is to catch over-sized switches generated by gcc on
6930 systems which don't support the broken .word hack.
6931 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6932 write.c (fixup_segment): check for signed .word overflow if
6933 WARN_SIGNED_OVERFLOW_WORD.
6935 * write.c (fixup_segment): fixed missing parens in expression
6936 checking for byte or word overflow.

6952 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6954 * input-scrub.c (input_scrub_push): call input_file_begin, not
6956 messages.c (as_perror): print ": " between the passed in error and
6957 the strerror, like perror does.
6959 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

6975 (write_object_file) call fixup_mdeps
6976 (fixup_segment) set fx_subsy to 0.
6977 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6979 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6982 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6984 * Makefile.in (LIBS): Include opcode library.
6986 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

7006 tc-i960.c (md_ri_to_chars): Always output bout object file in
7007 little endian byte order (used to use endianness of host).
7009 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7011 * config/tc-m68k.c (init_table): Now const. Always include 68851
7012 data, so that "bc" is available to 68040 cache instructions.
7013 Added "tt0", "tt1", and 68ec030 variants.
7014 (md_assemble): Complain if 68000 (only) and 68881 are specified.
7015 (enum _register): Added TT0, TT1.
7016 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
7017 line number correctly in "internal error" messages. Don't print
7018 architecture-mismatch message for operand errors.
7020 From Colin Smith (colin@wrs.com):
7021 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
7022 than install_operand.

7038 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
7039 so that we can assemble hand-written libgcc code.

7047 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
7049 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
7050 written with indirection on the last two operands, which can be
7051 either data or address registers. Added a new operand type 'r'
7052 which accepts either register type. Added '(' to notend stuff in
7053 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

7165 characteristics have been), default to 68020. Don't need extra
7166 quotes around error string.

7302 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
7304 * Makefile.in (install): Install into $(tooldir)/bin, since that's
7305 where gcc looks for it.
7307 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
7309 * Makefile.in: Changed some lines to be less confusing for some

7379 * expr.c (operand): if can't work out what sort of operand it is,
7380 then look through FLT_CHARS for a hint.
7382 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
7384 * Makefile.in, configure.in: removed traces of namesubdir,

7388 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
7389 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
7390 copyrights to '92, changed some from Cygnus to FSF.
7392 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7394 * expr.c: If an expression is single comma, then return with
7395 SEG_ABSENT rather than an error - since the sparc front end does
7396 really strange things with things like fbge,a
7398 * as.h: include bfd.h if using many sections
7399 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
7400 local labels didn't work.
7401 * listing.c (list_symbol_table): don't core dump when there's no
7403 * write.c, write.h: call fix_new with the right number of args on

7408 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7410 * app.c: MRI compatibility - allow single quote to start a string.
7411 * as.c: fix typo recently introduced.
7412 * as.h : Don't include aout/reloc.h - it's not right for COFF!
7413 * expr.c: Much rewriting, to accomodate MRI syntax for
7414 expressions. Also easier to read now.
7415 * listing.c: Put back defuns
7416 * read.c: modified to accept MRI syntax, put back listing pseudo
7417 ops so that an assembler built with NO_LISTING ignores list ops
7419 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7420 machine is a SPARC or a 29K.
7421 * config/obj-aout.c: added s_sect pseudo op
7422 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7423 fill in the timestamp.
7424 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7425 anymore, define all the relocs which the tc-<x> bit will use so we
7426 can translate from them to the coff types.
7427 * config/tc-a29k.c: reloc_type isn't ane enum any more
7428 * config/tc-m68k.c: Added NO_RELOC definition.
7430 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
7432 * Makefile.in: put header files before C source for TAGS; remove
7433 references to non-existent syscalls.h.
7435 * read.c, write.c subsegs.c: back out the .bss changes.
7437 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7439 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
7443 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7445 * symbols.c (local_label_name): symbols now start with ^A.
7447 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7448 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7449 generate these sections. .align: will use NOP_OPCODE or 0
7450 for padding. This is just for being nice to the
7453 * expr.c (operand): changed to generate local label "\001L0"
7454 starting with a ^A so that it is recognized as a local label.
7456 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7458 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7459 i/o opcodes - inb, inw, outb and outw. string manipulation with
7460 att syntax - scmp, slod, smov, ssca, ssto.
7462 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7463 to just after .file .
7465 In obj_crawl_symbol_chain() where it tries to put the external
7466 symbols apart, with the condition:
7467 (!S_IS_DEFINED(symbolP) &&
7468 !S_IS_DEBUG(symbolP) &&
7469 !SF_GET_STATICS(symbolP))
7470 it was moving too many symbols out. So I switch it back to the
7472 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7474 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7475 so that we don't use the F_RELFLG which make the linker complain
7476 that somebody has stripped the relocation info.
7478 Also, the AIX ld program require that the relocation table
7479 is sorted by r_vaddr like the standard ATT assembler does.
7481 [he also changed the sizeof(struct ...)'s into the coff
7482 style FOOSZ macros. I'm not sure this is right, but I can't
7483 remember why. xoxorich.]
7485 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
7487 * Makefile.in, configure.in, doc: use the doc. Build it, install

7492 * read.c: white space and comments only.
7494 * configure.in: use the new atof-ns32.c for ns32k.
7496 * write.c: comment change only.
7498 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7499 aren't yet integrated.
7501 * tc-i860.[hc]: blew off the dust. Something must still be done
7502 about conflicting relocation types.
7504 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7507 * tc-i960.c, tc-sparc.c: white space and comments only.
7509 * tc-a29k.h: delete duplicate macro definition.
7511 * new file atof-ns32k.c copied from hack's last unreleased gas.
7513 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7515 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7518 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7519 ChangeLog's prior to this are sketchy at best. I have logs.
7520 They just aren't ChangeLogs.
7527 version-control: never
