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

355 (control_regs): New pointer.
356 (m68k_ip): Use control_regs instead of testing CPU every time.

720 all arguments have been processed.

970 (lituse_pending): New variable. Set by anything that generates a
971 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
972 tested by code that might want to emit a LITUSE reloc.
973 (emit_unaligned_io): New function. Currently calls md_assemble,
974 but it should eventually be converted to generate the insn itself
975 and call emit_insn directly.
976 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
977 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
978 emit_bis_r): Likewise.

1006 (load_address): Handle EMBEDDED_PIC.
1007 (macro): Handle EMBEDDED_PIC in all PIC cases.
1008 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
1009 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
1010 -non_shared to use NO_PIC (this is how the Irix 5 assembler
1011 works). Do not permit -G with SVR4_PIC.
1012 (s_abicalls): Warn if -G was used, and force -G 0.
1013 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
1014 anything but a.out, not just for ELF. For ECOFF, don't generate a

1017 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
1019 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1021 * config/tc-hppa.c (create_new_space): Use ints, not chars as
1022 parameters to avoid losing when compiling with HP CC.
1023 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
1025 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1027 * Makefile.in (config-stamp): If `defs' is defined, emit a
1028 preprocessor directive to create a macro named by this value into
1029 config.new; don't explicitly go for BFD_ASSEMBLER.
1030 * configure.in: Define `defs', not `BFDDEF'. Set it to
1031 MANY_SEGMENTS for any obj-coffbfd target.
1032 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
1033 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
1035 (LOCAL_LOADLIBES): Deleted.
1036 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
1037 * config/m88kcoff.mt (TDEFINES): Ditto.

1063 bfd_set_symtab is called.
1064 (dump_section_relocs): Note whether a symbol is a section symbol
1066 (adjust_reloc_syms): For now, always supply an absolute symbol for
1067 fixups without symbols but not yet `done'. Use section_symbol to
1068 get the symbol, instead of going directly for abs_symbol.
1069 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
1070 reloc is not a section symbol and is not in the symbol table.
1071 (set_symtab): New function, broken out from write_object_file.
1072 Counts symbol table instead of relying on an earlier count.
1073 (write_object_file): Call set_symtab, but do it after potentially
1074 invoking the *_frob_file macros. Don't bother counting symbols.
1075 Call symbol_remove, instead of expanding it in place. Moved the
1076 conditionalized `object_file_size' declaration down to
1077 conditionalized block where it's used. When using the absolute
1078 symbol for a fixup without a symbol, set sy_used_in_reloc.
1079 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
1080 the correct symbol for the absolute section.
1082 * subsegs.c (section_symbol): Use symbol_new instead of
1083 symbol_make, since we may want it to go into the symbol table.
1084 Make the new symbol have internal linkage. If
1085 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
1086 symbol with the newly created GAS symbol.
1087 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
1088 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

1095 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
1096 (sparc_ip, label "immediate"): Reject constants for pcrel
1097 instructions only if the relocation type indicates a "call"
1098 instruction and the offset is within range of a "jmpl %g0". If
1099 it's not in range, use the absolute section symbol plus an offset.
1100 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
1102 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
1104 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
1107 * configure.in: Eliminated all targets using obj-coff but not
1108 defining BFD_ASSEMBLER; I think all such targets that are
1109 supported will be matched by real CPU-OS combinations earlier in
1111 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
1112 some comments about the dpx2 configuration, but left it disabled,
1113 since it couldn't be reached before.
1114 (target a29k-amd-ebmonold): Deleted.

1124 the 'j' operand if there are no further alternatives for this
1127 * config/obj-coffbfd.c (adjust_stab_section): Initialize
1128 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
1129 is not SEG_UNKNOWN rather than checking whether it is >= 0.
1131 * config/tc-mips.c (mips_align): Take new argument, label, and use
1132 it instead of global insn_label.
1133 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
1134 call to mips_emit_delay and pass it to mips_align.
1136 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1138 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.

1149 S_IS_EXTERNAL when deciding whether to discard a symbol.
1151 * config-gas.com: Scan Makefile.in, not version.c, for current
1152 version number. Delete all versions of temp files when finished
1153 with them. Create config.h.

1156 values to reduce number of lookups with S_GET_VALUE. Skip debug
1157 symbols to avoid "a really nasty bug". (From Holger Teutsch,
1158 holger@botbso.rhein-main.de.)
1159 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
1160 field. (Also from Holger Teutsch.) Watch for a would-be register
1161 mask that spans frags.
1163 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
1164 this_base, not line_base. (Patch from Andreas Arens,

1168 look local if they're exported or undefined. Used to be done for
1171 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

1175 (lex_type): Use it for `%'.
1177 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

3296 OPTIONAL_REGISTER_PREFIX if either is already defined.
3298 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
3300 * configure.in: Set bfd_gas for all sparc targets. Added facility
3301 for keeping or rejecting configurations still under development;
3302 default is to assume production environment, and reject configs
3303 still being worked on. Mark Elf configurations (except sparc and
3304 i386) as developmental. Deleted cases matching some generic names
3305 in favor of more specific names. (E.g., when we get Alpha
3306 support, we'll still only support VMS for Vax.)
3308 * config/tc-sparc.h (md_end): New macro.
3309 * config/tc-sparc.c (md_end): Function deleted.
3310 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd
3311 version compiling. All sparc targets will use bfd now.

3320 against placing additional object-file dependent code here. Warn
3321 against contaminating all of GAS with the internals of tc-hppa.c
3322 through inclusion of tc-hppa.h. Delete all forward declarations
3323 for functions only used within tc-hppa.c, likewise for structures,
3324 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
3325 conditional code in a few small places.
3327 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3328 structures, global variables, forward declarations together.
3329 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
3330 conditional code -- try to group conditional code together
3331 into a few places. Make all functions and variables which
3332 are only used within tc-hppa.c static. PARAMize all functions.
3333 Add comments to functions. Delete unused functions, variables,
3334 #defines, etc. Delete unused members within structures. Delete
3335 ldil;ble hacks -- it is believed they were installed to work
3336 around old gas bugs. Avoid using mixed case for local
3337 functions, variables, and structures. Fix formatting problems
3338 not found by GNU-indent. Add FIXME notices for things which
3339 should be worked on the near future. Delete lots of old
3340 useless (1.36 PA-SOM) code.

3352 which do not involve function symbols.
3354 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
3355 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
3357 * config/tc-hppa.c: Likewise.
3359 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
3360 of elf32_symbol_type.
3361 (pa_export_args): Likewise.
3362 (elf_hppa_final_processing): Likewise.
3363 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

3368 * config/tc-hppa.c: (md_section_align): Align all sections to
3369 a multiple of the section alignment rather than always a
3372 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
3373 bits are zero (eg they specify no relocations), then do not even
3374 bother adding their entries to thesymextn section.

3415 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
3416 call strchr for each character to see if it is a special char,
3417 instead add a second loop over special_chars. Set alignment
3418 of text, data and bss sections to 4.
3419 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3421 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3422 ELF, since the ELF object format does not have these type of
3423 relocations. Change the abort into as as_bad and return
3424 BFD_RELOC_NONE to silence compiler warnings.
3425 (md_assemble): Keep track of the instruction size. Allow white
3426 space between the $ and the constant for compatibility with older
3427 gases and other assemblers.

5811 a29k .bss section; the mondfe program doesn't like it.

5832 source directory, if that's not the current directory.
5834 * configure.in (per-host): Accept MIPS host with BSD version

5860 avoid some redefinition complaints on some systems.
5861 (const, volatile): Don't need these conditionally defined if we
5862 use CONST and VOLATILE from ansidecl.h.
5863 (seg_name): Use CONST, not const.
5865 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5867 * config/tc-mips.c: Reindented to GNU standards.
5869 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
5871 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5872 (fixup_segment): Add a29k special case; the linker is not prepared
5873 to see a segment offset here.
5875 * app.c (do_scrub_next_char): Added new state, 10, modifying state
5876 9 to only keep a space in between identifier characters.
5878 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5880 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5881 srcdir, might be in objdir.
5883 * doc/Makefile.in: dvi depends on as.dvi

5911 dropping a space immediately following an identifier.
5912 * expr.c, write.c: Rewrote assert expressions to not use multiple
5913 lines; I don't think that can be done portably.
5914 * config/tc-mips.c (macro): Use $AT if target register is zero in
5915 load instruction, which it can be for a floating point load.

5928 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
5929 z8k-opc.h, not z8k.h.
5931 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
5934 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

5989 prototypes for all static functions. Moved existing minimal
5990 debugging format support info #ifndef OBJ_ECOFF blocks.

6039 * make-gas.com: Find obstack.obj if it's not in the current
6041 * read.c (s_ignore): Don't declare is_end_of_line. It's
6042 redundant, and triggers a VMS gcc compiler bug.
6044 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
6045 current segment as an argument. (Ignored in all cases but VMS.)
6046 All callers and definitions changed.

6064 argument to s_ignore. Put "#if 0" around unused code.
6065 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
6066 Call elf_xstabs for .stabs and .xstabs operators.
6068 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
6070 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
6073 * configure.in: mips-bsd configuration was missing format spec.
6076 * Makefile.in (Makefile): Depends on configure.in.
6078 * config/tc-mips.c (append_insn): Don't check for alignment of
6079 frag in memory; alignment of instructions in section is a separate
6082 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
6085 * listing.h: Always provide function declarations, not macros, so
6088 Tue Mar 2 00:50:43 1993 John Gilmore (gnu@cygnus.com)

6373 * expr.c (operand): If character other than comma or newline is a
6374 logical end-of-line character, use the newline case.

6377 (operand): Treat zero byte as end-of-operand.
6379 * configure.in (per-target): Look for with_bfd_assembler option.
6380 For now, only accept "no", until the merge is done.
6382 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):

6392 md_[long,short]_jump_size. Remove declaration of const_flag
6393 (which will be declared in obj-vms.h).
6394 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6395 Fix arguments to VMS_write_object_file.
6396 * config-gas.com: New file. Script for VMS systems to set up the

6405 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6406 types of malformed stabs. Change parsing algorithm so that we are
6407 more certain of having all of the information that we need on hand.
6408 * obj-vms.c (final_forward_reference): New function, used to help
6409 resolve the data types of as many struct elements as possible

6427 SEG_DATA or SEG_E1 if needed.
6428 (s_lcomm): Likewise with bss_section.
6429 (s_fill): Use memset, not bzero.

6458 if these are used or defined, if BFD_ASSEMBLER.
6459 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6460 subseg_new split into two functions.
6461 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6463 * as.h (volatile): Don't define if already defined.
6464 (had_errors, had_warnings): Provide prototypes for ANSI C even if

6499 (size_section): Restored sanity check.
6500 (do_relocs_for): Base section address on s_paddr rather than
6501 computing it. Adjust a29k R_IHIHALF special case to account for

6503 reclos, set s_relptr to 0. Set relocation size in object_headers.
6504 (fill_section): Always set s_vaddr here, removing
6505 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6506 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6507 Set STYP_INFO for .comment.

6511 H_{SET,GET}_* macros.
6512 (do_linenos_for): Set lineno size in object_headers.
6513 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6514 set s_vaddr here. If string_byte_count remains 4, set it back to
6515 0, and only write strings out if there are some. Call
6516 fill_section before do_relocs_for and do_linenos_for.
6517 (obj_coff_section): Handle optional quoted second argument giving
6518 section characteristics.
6519 (obj_coff_bss): Added to handle .bss.

6540 (do_scrub_next_char): For \", return " not '.
6541 (symbol_chars): Now const.
6543 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6544 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6546 * config/obj-coff.h: Don't use #elif.
6548 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6549 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

6579 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6580 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6581 definitions, and don't merge tags with non-tags. Check for .bf
6582 rather than just checking whether the second character is b and
6583 the third character is f.
6584 (obj_coff_val): gcc can generate values which we don't handle

6588 (yank_symbols): Don't merge labels.
6589 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6735 could be doing emulation.
6737 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6740 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
6743 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)

6810 * Support for i386-sysv.
6811 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6851 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6853 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6854 #elif, since it is not supported by old compilers.
6855 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6856 couple of expressions in tc-m68k.c.
6858 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

6884 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6886 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6887 sections starting from zero, rather than making them consecutive.
6888 This makes subsequent reloc calculations easier, esp if the object
6889 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6890 allocate lcomm in .data rather than in .bss. It seems that some
6891 tools can't cope with a non-zero sized bss before linkage.
6893 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6895 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6896 throughout. That enum no longer means what we thought it meant.

6914 * Makefile.in (install): if $(tooldir) exists, install as in
6917 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6919 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6920 .word is < -32768 or > 32767. The -J flag causes the error to be
6921 ignored. This is to catch over-sized switches generated by gcc on
6922 systems which don't support the broken .word hack.
6923 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6924 write.c (fixup_segment): check for signed .word overflow if
6925 WARN_SIGNED_OVERFLOW_WORD.
6927 * write.c (fixup_segment): fixed missing parens in expression
6928 checking for byte or word overflow.

6944 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6946 * input-scrub.c (input_scrub_push): call input_file_begin, not
6948 messages.c (as_perror): print ": " between the passed in error and
6949 the strerror, like perror does.
6951 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

6968 (fixup_segment) set fx_subsy to 0.
6969 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6971 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6974 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6976 * Makefile.in (LIBS): Include opcode library.
6978 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6998 tc-i960.c (md_ri_to_chars): Always output bout object file in
6999 little endian byte order (used to use endianness of host).
7001 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7003 * config/tc-m68k.c (init_table): Now const. Always include 68851
7004 data, so that "bc" is available to 68040 cache instructions.
7005 Added "tt0", "tt1", and 68ec030 variants.
7006 (md_assemble): Complain if 68000 (only) and 68881 are specified.
7007 (enum _register): Added TT0, TT1.
7008 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
7009 line number correctly in "internal error" messages. Don't print
7010 architecture-mismatch message for operand errors.
7012 From Colin Smith (colin@wrs.com):
7013 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
7014 than install_operand.

7028 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
7030 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
7031 so that we can assemble hand-written libgcc code.
7033 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7035 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
7036 has already been formatted (but may still contain %-characters).
7039 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
7041 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
7042 written with indirection on the last two operands, which can be
7043 either data or address registers. Added a new operand type 'r'
7044 which accepts either register type. Added '(' to notend stuff in
7045 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

7157 characteristics have been), default to 68020. Don't need extra
7158 quotes around error string.

7242 * write.c (write_object_file): keep the fix_tail clean, which
7243 fixes a bug in -R where relocations were being lost.
7245 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
7247 * configure.in: recognize m680x0 as having sun3 emulation mode for

7292 start addresses to match required alignment.
7294 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
7296 * Makefile.in (install): Install into $(tooldir)/bin, since that's
7297 where gcc looks for it.
7299 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
7301 * Makefile.in: Changed some lines to be less confusing for some

7367 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
7369 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
7371 * expr.c (operand): if can't work out what sort of operand it is,
7372 then look through FLT_CHARS for a hint.
7374 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
7376 * Makefile.in, configure.in: removed traces of namesubdir,

7378 copyrights to '92, changed some from Cygnus to FSF.
7380 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
7381 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
7382 copyrights to '92, changed some from Cygnus to FSF.
7384 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7386 * expr.c: If an expression is single comma, then return with
7387 SEG_ABSENT rather than an error - since the sparc front end does
7388 really strange things with things like fbge,a
7390 * as.h: include bfd.h if using many sections
7391 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
7392 local labels didn't work.
7393 * listing.c (list_symbol_table): don't core dump when there's no
7395 * write.c, write.h: call fix_new with the right number of args on
7397 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
7400 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7402 * app.c: MRI compatibility - allow single quote to start a string.
7403 * as.c: fix typo recently introduced.
7404 * as.h : Don't include aout/reloc.h - it's not right for COFF!
7405 * expr.c: Much rewriting, to accomodate MRI syntax for
7406 expressions. Also easier to read now.
7407 * listing.c: Put back defuns
7408 * read.c: modified to accept MRI syntax, put back listing pseudo
7409 ops so that an assembler built with NO_LISTING ignores list ops
7411 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7412 machine is a SPARC or a 29K.
7413 * config/obj-aout.c: added s_sect pseudo op
7414 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7415 fill in the timestamp.
7416 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7417 anymore, define all the relocs which the tc-<x> bit will use so we
7418 can translate from them to the coff types.
7419 * config/tc-a29k.c: reloc_type isn't ane enum any more
7420 * config/tc-m68k.c: Added NO_RELOC definition.
7422 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
7424 * Makefile.in: put header files before C source for TAGS; remove
7425 references to non-existent syscalls.h.
7427 * read.c, write.c subsegs.c: back out the .bss changes.
7429 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7431 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
7435 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7437 * symbols.c (local_label_name): symbols now start with ^A.
7439 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7440 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7441 generate these sections. .align: will use NOP_OPCODE or 0
7442 for padding. This is just for being nice to the
7445 * expr.c (operand): changed to generate local label "\001L0"
7446 starting with a ^A so that it is recognized as a local label.
7448 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7450 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7451 i/o opcodes - inb, inw, outb and outw. string manipulation with
7452 att syntax - scmp, slod, smov, ssca, ssto.
7454 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7455 to just after .file .
7457 In obj_crawl_symbol_chain() where it tries to put the external
7458 symbols apart, with the condition:
7459 (!S_IS_DEFINED(symbolP) &&
7460 !S_IS_DEBUG(symbolP) &&
7461 !SF_GET_STATICS(symbolP))
7462 it was moving too many symbols out. So I switch it back to the
7464 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7466 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7467 so that we don't use the F_RELFLG which make the linker complain
7468 that somebody has stripped the relocation info.
7470 Also, the AIX ld program require that the relocation table
7471 is sorted by r_vaddr like the standard ATT assembler does.
7473 [he also changed the sizeof(struct ...)'s into the coff
7474 style FOOSZ macros. I'm not sure this is right, but I can't
7475 remember why. xoxorich.]
7477 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

7486 * configure.in: use the new atof-ns32.c for ns32k.
7488 * write.c: comment change only.
7490 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7491 aren't yet integrated.
7493 * tc-i860.[hc]: blew off the dust. Something must still be done
7494 about conflicting relocation types.
7496 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7499 * tc-i960.c, tc-sparc.c: white space and comments only.
7501 * tc-a29k.h: delete duplicate macro definition.
7503 * new file atof-ns32k.c copied from hack's last unreleased gas.
7505 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7507 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7510 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7511 ChangeLog's prior to this are sketchy at best. I have logs.
7512 They just aren't ChangeLogs.
7519 version-control: never
