143 * config/obj-coff.c (coff_frob_symbol): Use C_STAT for the .text
144 section symbol, not C_LABEL.
146 * config/tc-mips.c (mips_ip): Permit a modifier in 'o' case, and

198 * read.c (emit_expr): Use memset to zero out memory, rather than
199 going through md_number_to_chars. This permits handling symbolic
200 arguments when the size is larger than sizeof (valueT), if
201 TC_CONS_FIX_NEW is prepared to handle the case (as it is on MIPS).

253 (control_regs): New pointer.
254 (m68k_ip): Use control_regs instead of testing CPU every time.

701 directory, and specify PSECT attributes explicitly to linker.
702 Also added missing label.
703 * Makefile.in (stamp-mk.com): Reference new variable
704 VMS_OTHER_OBJS for list of non-local object files, instead of

792 don't spew remainder of input file in error message.
793 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
794 message with reloc type and try to process remainder of file.

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

887 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
888 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

960 * write.c (symbol_table_frozen): New variable, to be set after
961 bfd_set_symtab is called.
962 (dump_section_relocs): Note whether a symbol is a section symbol
964 (adjust_reloc_syms): For now, always supply an absolute symbol for
965 fixups without symbols but not yet `done'. Use section_symbol to
966 get the symbol, instead of going directly for abs_symbol.
967 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
968 reloc is not a section symbol and is not in the symbol table.
969 (set_symtab): New function, broken out from write_object_file.
970 Counts symbol table instead of relying on an earlier count.
971 (write_object_file): Call set_symtab, but do it after potentially
972 invoking the *_frob_file macros. Don't bother counting symbols.
973 Call symbol_remove, instead of expanding it in place. Moved the
974 conditionalized `object_file_size' declaration down to
975 conditionalized block where it's used. When using the absolute
976 symbol for a fixup without a symbol, set sy_used_in_reloc.
977 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
978 the correct symbol for the absolute section.
980 * subsegs.c (section_symbol): Use symbol_new instead of
981 symbol_make, since we may want it to go into the symbol table.
982 Make the new symbol have internal linkage. If
983 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
984 symbol with the newly created GAS symbol.
985 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
986 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

991 (in_signed_range): New function.
993 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
994 (sparc_ip, label "immediate"): Reject constants for pcrel
995 instructions only if the relocation type indicates a "call"
996 instruction and the offset is within range of a "jmpl %g0". If
997 it's not in range, use the absolute section symbol plus an offset.
998 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
1000 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
1002 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
1005 * configure.in: Eliminated all targets using obj-coff but not
1006 defining BFD_ASSEMBLER; I think all such targets that are
1007 supported will be matched by real CPU-OS combinations earlier in
1009 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
1010 some comments about the dpx2 configuration, but left it disabled,
1011 since it couldn't be reached before.
1012 (target a29k-amd-ebmonold): Deleted.

1022 the 'j' operand if there are no further alternatives for this
1025 * config/obj-coffbfd.c (adjust_stab_section): Initialize
1026 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
1027 is not SEG_UNKNOWN rather than checking whether it is >= 0.
1029 * config/tc-mips.c (mips_align): Take new argument, label, and use
1030 it instead of global insn_label.
1031 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
1032 call to mips_emit_delay and pass it to mips_align.
1034 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1036 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
1038 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
1039 argument to a .callinfo directive. Don't loop forever on errors.

1047 S_IS_EXTERNAL when deciding whether to discard a symbol.
1049 * config-gas.com: Scan Makefile.in, not version.c, for current
1050 version number. Delete all versions of temp files when finished
1051 with them. Create config.h.
1053 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
1054 values to reduce number of lookups with S_GET_VALUE. Skip debug
1055 symbols to avoid "a really nasty bug". (From Holger Teutsch,
1056 holger@botbso.rhein-main.de.)
1057 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
1058 field. (Also from Holger Teutsch.) Watch for a would-be register
1059 mask that spans frags.
1061 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
1062 this_base, not line_base. (Patch from Andreas Arens,

3201 still being worked on. Mark Elf configurations (except sparc and
3202 i386) as developmental. Deleted cases matching some generic names
3203 in favor of more specific names. (E.g., when we get Alpha

3230 are only used within tc-hppa.c static. PARAMize all functions.
3231 Add comments to functions. Delete unused functions, variables,
3232 #defines, etc. Delete unused members within structures. Delete
3233 ldil;ble hacks -- it is believed they were installed to work
3234 around old gas bugs. Avoid using mixed case for local
3235 functions, variables, and structures. Fix formatting problems
3236 not found by GNU-indent. Add FIXME notices for things which
3237 should be worked on the near future. Delete lots of old

4400 * Extensive changes to permit symbols to contain any expression
4401 type and to delay the computation of the expression until the
4402 value is actually needed. This permits setting symbols to values
4403 calculated based on object code size. Expressions were changed to
4404 no longer be in a section, to stop the overloading of segment and
4405 expression type that previously occurred.
4407 * as.c (big_section, pass1_section, diff_section, absent_section):
4409 (expr_section): Added (used for dummy symbols which hold

4493 (previous_section, previous_subsection): New vars.
4494 (obj_elf_section): Save current place in case DWARF code wants us
4495 to pop back to it. Handle unquoted section name as well as quoted
4496 section name. Don't crash on invalid strings.
4497 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

4606 * Removed sy_forward and replaced it with an undefined expression
4607 as the value of a symbol.
4608 * struc-symbol.h (struct symbol): Removed sy_forward field. Added
4609 sy_resolved and sy_resolving single bit fields.
4610 * symbols.c (symbol_new): Don't initialize sy_forward field.

4614 * read.c (pseudo_set): Set symbolP->sy_value to an undefined
4615 expression rather than setting symbolP->sy_forward.
4616 * write.c (write_object_file): Use resolve_symbol_value on
4617 symbols, keeping the common case (the old behaviour) inline.
4618 * config/obj-aout.c (obj_aout_frob_symbol): Removed sy_forward
4619 handling (subsumed by write.c change).
4620 * config/obj-coff.c, config/obj-coffbfd.c (obj_coff_val): Set

5644 than ECOFF line number information.
5645 (obj_ecoff_stab): Accept non-zero values for stabs line number.

5706 dependencies are read, not when they are used).
5708 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
5709 a29k .bss section; the mondfe program doesn't like it.

5730 source directory, if that's not the current directory.
5732 * configure.in (per-host): Accept MIPS host with BSD version

5754 process relocs if there aren't any relocs to process. Avoids
5755 malloc/free bug on SCO too.

5758 avoid some redefinition complaints on some systems.
5759 (const, volatile): Don't need these conditionally defined if we
5760 use CONST and VOLATILE from ansidecl.h.
5761 (seg_name): Use CONST, not const.
5763 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5765 * config/tc-mips.c: Reindented to GNU standards.
5767 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
5769 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5770 (fixup_segment): Add a29k special case; the linker is not prepared
5771 to see a segment offset here.
5773 * app.c (do_scrub_next_char): Added new state, 10, modifying state

5776 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5778 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5779 srcdir, might be in objdir.

5809 dropping a space immediately following an identifier.
5810 * expr.c, write.c: Rewrote assert expressions to not use multiple
5811 lines; I don't think that can be done portably.
5812 * config/tc-mips.c (macro): Use $AT if target register is zero in
5813 load instruction, which it can be for a floating point load.
5815 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5826 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
5827 z8k-opc.h, not z8k.h.
5829 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
5832 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5834 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
5836 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5838 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

5887 prototypes for all static functions. Moved existing minimal
5888 debugging format support info #ifndef OBJ_ECOFF blocks.

5937 * make-gas.com: Find obstack.obj if it's not in the current
5939 * read.c (s_ignore): Don't declare is_end_of_line. It's
5940 redundant, and triggers a VMS gcc compiler bug.
5942 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5943 current segment as an argument. (Ignored in all cases but VMS.)
5944 All callers and definitions changed.

5966 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
5968 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
5971 * configure.in: mips-bsd configuration was missing format spec.
5974 * Makefile.in (Makefile): Depends on configure.in.
5976 * config/tc-mips.c (append_insn): Don't check for alignment of
5977 frag in memory; alignment of instructions in section is a separate

5997 * config/tc-sparc.c (s_xword): Now call big_cons, so large
5998 constants are accepted, but symbolic values are not. GCC will not
5999 generate the latter currently.
6001 * frags.c (frag_init): New function.
6002 (zero_address_frag, bss_address_frag): Now initialized at run
6004 * as.c (main): Call frag_init.

6047 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
6048 (fixup_segment): Make sure common-section symbols get treated the
6049 same as undefined symbols.
6050 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type
6051 bfd_reloc_code_real_type. Use seg_fix_{root,tail}P derived from

6058 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and
6061 * symbols.c (symbol_new): Argument NAME is now pointer to const.
6062 Simplified STRIP_UNDERSCORE code. Remove assumptions about null
6063 pointers in freshly allocated storage. [BFD_ASSEMBLER]: Get new

6080 new section/subsection.
6082 * read.c: Don't include ctype.h.
6083 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
6084 for now; should be machine-dependent.
6086 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
6087 targets, forcing BFD use.
6089 Wed Feb 17 18:59:03 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
6091 * config/tc-sparc.c: Use PARAMS macro for static function
6092 declarations. Use BFD_RELOC_ macros everywhere, with
6093 compatibility macros declared for non-BFD mode.
6094 (struct sparc_it) [BFD_ASSEMBLER]: Use bfd_reloc_code_real_type
6095 instead of enum reloc_type.

6256 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
6257 latter, instead of selecting with preprocessor conditionals.
6259 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
6261 * configure.in: recognise all sparclite variants

6271 * expr.c (operand): If character other than comma or newline is a
6272 logical end-of-line character, use the newline case.
6273 From Eric Youngdale:
6274 (operand): Set X_add_number field for floating-point numbers.
6275 (operand): Treat zero byte as end-of-operand.
6277 * configure.in (per-target): Look for with_bfd_assembler option.
6278 For now, only accept "no", until the merge is done.
6280 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
6281 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
6282 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
6283 * read.c: Finish conversion to S_* macros in the VMS only
6284 parts of the program. Add "const" modifier to hex_value.
6285 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
6287 * expr.c: Add "const" modifier to hex_value.
6288 * symbols.c: Finish conversion to S_* macros in the VMS only
6289 parts of the program. Add "const" modifier to
6290 md_[long,short]_jump_size. Remove declaration of const_flag
6291 (which will be declared in obj-vms.h).
6292 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6293 Fix arguments to VMS_write_object_file.
6294 * config-gas.com: New file. Script for VMS systems to set up the
6295 configuration to build gas for VMS, and create config.status.
6296 * make-gas.com: Redone to work with new scheme.
6297 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
6299 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
6300 will swap bytes if needed on a big endian system. Use throughout
6302 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
6303 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6304 types of malformed stabs. Change parsing algorithm so that we are
6305 more certain of having all of the information that we need on hand.
6306 * obj-vms.c (final_forward_reference): New function, used to help
6307 resolve the data types of as many struct elements as possible
6308 when some part of the struct is not fully defined by the compiler.

6311 * obj-vms.c (VMS_write_object_file): Define all vtable psects
6312 as symbols as well in the object file. Look for external functions

6314 g++ compiler is incapable of doing this.
6315 * tc-vax.c: Add '1' option for backward compatibility with older GCC
6317 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
6318 * input-scrub.c (as_where): Fix bug where as would crash if we did not
6319 have the name of the source file yet.
6320 * config/ho-vms.h: define HO_VMS, not HO_VAX.
6322 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
6324 * read.c (s_data): Always use "data_section", since it'll map to
6325 SEG_DATA or SEG_E1 if needed.
6326 (s_lcomm): Likewise with bss_section.
6327 (s_fill): Use memset, not bzero.
6329 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

6351 (big_section, reg_section, pass1_section, diff_section,
6352 absent_section, text_section, data_section, bss_section): If
6353 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
6354 mapping to segT enum values.
6355 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
6356 if these are used or defined, if BFD_ASSEMBLER.
6357 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6358 subseg_new split into two functions.
6359 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6361 * as.h (volatile): Don't define if already defined.
6362 (had_errors, had_warnings): Provide prototypes for ANSI C even if
6364 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
6365 declare with format attribute for -Wformat checking.
6367 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
6369 * app.c, config/tc-*.c: Don't include read.h, since it is already
6372 * These are based on patches from Minh Tran-le
6373 <mtranle@paris.intellicorp.com>.
6374 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
6375 obj_format coffbfd and gas_target i386coff for target.
6376 (i[34]86-*-isc*): New host (uses sysv).
6377 * config/i386aix.mt: Removed (no longer used).
6378 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
6380 (LDFLAGS): Added, defined as -shlib.
6381 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
6382 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6383 (DOT_LABEL_PREFIX): Define.
6384 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
6385 name rather than L0\001.
6386 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
6388 * symbols.c, symbols.h (local_bss_counter): Removed.

6397 (size_section): Restored sanity check.
6398 (do_relocs_for): Base section address on s_paddr rather than
6399 computing it. Adjust a29k R_IHIHALF special case to account for
6400 section paddr (used to require paddr to be zero). If there are no
6401 reclos, set s_relptr to 0. Set relocation size in object_headers.
6402 (fill_section): Always set s_vaddr here, removing
6403 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6404 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6405 Set STYP_INFO for .comment.
6406 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
6407 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

6409 H_{SET,GET}_* macros.
6410 (do_linenos_for): Set lineno size in object_headers.
6411 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6412 set s_vaddr here. If string_byte_count remains 4, set it back to
6413 0, and only write strings out if there are some. Call
6414 fill_section before do_relocs_for and do_linenos_for.
6415 (obj_coff_section): Handle optional quoted second argument giving
6416 section characteristics.
6417 (obj_coff_bss): Added to handle .bss.
6418 (obj_coff_ident): Added to handle .ident (puts string in .comment

6438 (do_scrub_next_char): For \", return " not '.
6439 (symbol_chars): Now const.
6441 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6442 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6444 * config/obj-coff.h: Don't use #elif.
6446 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6447 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
6449 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
6451 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

6471 SEG_BSS, fill with NOP_OPCODE.
6472 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
6473 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6474 using ZERO_BASED_SEGMENTS.
6475 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6476 never set segment address for SEG_E2 (.bss) and don't write out
6477 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6478 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6479 definitions, and don't merge tags with non-tags. Check for .bf
6480 rather than just checking whether the second character is b and
6481 the third character is f.
6482 (obj_coff_val): gcc can generate values which we don't handle
6483 correctly; discard information for now, since it only affects the
6484 debugging information.
6485 (tag_find_or_name): Don't insert tags in the symbol table.
6486 (yank_symbols): Don't merge labels.
6487 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6507 power-of-two alignment for .align.
6509 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
6510 and leave everything else alone.

6541 * doc/as.texinfo: Regrouped documentation of some command-line
6542 options. Updated options documentation for m68k. Some minor
6543 wording/punctuation changes.
6545 Mon Nov 30 11:42:11 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6547 * configure.in: Accept target OS "vms".
6549 * symbols.c: Merged ANSI and non-ANSI function decls, using

6599 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
6601 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
6604 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.

6633 could be doing emulation.
6635 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6638 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6667 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6669 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6670 constant will not fit in an immediate field.
6671 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

6708 * Support for i386-sysv.
6709 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6751 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6752 #elif, since it is not supported by old compilers.
6753 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6754 couple of expressions in tc-m68k.c.
6756 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6758 * read.c (cons): If NO_RELOC is defined, use it.
6760 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6762 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6764 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6765 local labels to start with a .) and set REGISTER_PREFIX to %.
6766 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

6784 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6785 sections starting from zero, rather than making them consecutive.
6786 This makes subsequent reloc calculations easier, esp if the object
6787 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6788 allocate lcomm in .data rather than in .bss. It seems that some
6789 tools can't cope with a non-zero sized bss before linkage.
6791 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6793 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

6812 * Makefile.in (install): if $(tooldir) exists, install as in
6815 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6817 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6818 .word is < -32768 or > 32767. The -J flag causes the error to be
6819 ignored. This is to catch over-sized switches generated by gcc on
6820 systems which don't support the broken .word hack.
6821 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6822 write.c (fixup_segment): check for signed .word overflow if
6823 WARN_SIGNED_OVERFLOW_WORD.
6825 * write.c (fixup_segment): fixed missing parens in expression
6826 checking for byte or word overflow.

6842 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6844 * input-scrub.c (input_scrub_push): call input_file_begin, not
6846 messages.c (as_perror): print ": " between the passed in error and
6847 the strerror, like perror does.

6852 From Steve Chamberlain:
6853 Makefile.in: Handle m68*-*-coff*.
6854 read.c, read.h: add mult argument to s_space
6856 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6857 Motorola and MIT syntax; gas can now assemble either type of
6859 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6866 (fixup_segment) set fx_subsy to 0.
6867 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6869 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6872 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6874 * Makefile.in (LIBS): Include opcode library.
6876 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6899 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6901 * config/tc-m68k.c (init_table): Now const. Always include 68851
6902 data, so that "bc" is available to 68040 cache instructions.
6903 Added "tt0", "tt1", and 68ec030 variants.
6904 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6905 (enum _register): Added TT0, TT1.
6906 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6907 line number correctly in "internal error" messages. Don't print
6908 architecture-mismatch message for operand errors.
6910 From Colin Smith (colin@wrs.com):
6911 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6912 than install_operand.

6928 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6929 so that we can assemble hand-written libgcc code.

6933 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6934 has already been formatted (but may still contain %-characters).
6937 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6939 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6940 written with indirection on the last two operands, which can be
6941 either data or address registers. Added a new operand type 'r'
6942 which accepts either register type. Added '(' to notend stuff in
6943 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6945 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

6961 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6962 their not having symbols associated.
6964 * tc-i960.c (norelax, instrument_branches): Default initializer is
6966 (linkrelax): Delete variable definition.

6990 being used with args swapped, causing occasional lossage when
6991 refilling buffers after an include file.
6993 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
6995 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6996 version. Discard bogus DONTDEF version.

7001 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
7002 selected architecture, print a message saying so and listing what

7192 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
7194 * Makefile.in (install): Install into $(tooldir)/bin, since that's
7195 where gcc looks for it.
7197 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
7199 * Makefile.in: Changed some lines to be less confusing for some

7265 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
7267 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
7269 * expr.c (operand): if can't work out what sort of operand it is,
7270 then look through FLT_CHARS for a hint.
7272 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
7274 * Makefile.in, configure.in: removed traces of namesubdir,

7276 copyrights to '92, changed some from Cygnus to FSF.
7278 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
7279 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
7280 copyrights to '92, changed some from Cygnus to FSF.
7282 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7284 * expr.c: If an expression is single comma, then return with
7285 SEG_ABSENT rather than an error - since the sparc front end does
7286 really strange things with things like fbge,a
7288 * as.h: include bfd.h if using many sections
7289 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
7290 local labels didn't work.
7291 * listing.c (list_symbol_table): don't core dump when there's no
7293 * write.c, write.h: call fix_new with the right number of args on
7295 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
7298 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7300 * app.c: MRI compatibility - allow single quote to start a string.
7301 * as.c: fix typo recently introduced.
7302 * as.h : Don't include aout/reloc.h - it's not right for COFF!
7303 * expr.c: Much rewriting, to accomodate MRI syntax for
7304 expressions. Also easier to read now.
7305 * listing.c: Put back defuns
7306 * read.c: modified to accept MRI syntax, put back listing pseudo
7307 ops so that an assembler built with NO_LISTING ignores list ops
7309 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7310 machine is a SPARC or a 29K.
7311 * config/obj-aout.c: added s_sect pseudo op
7312 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7313 fill in the timestamp.
7314 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7315 anymore, define all the relocs which the tc-<x> bit will use so we
7316 can translate from them to the coff types.
7317 * config/tc-a29k.c: reloc_type isn't ane enum any more
7318 * config/tc-m68k.c: Added NO_RELOC definition.
7320 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
7322 * Makefile.in: put header files before C source for TAGS; remove
7323 references to non-existent syscalls.h.
7325 * read.c, write.c subsegs.c: back out the .bss changes.
7327 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7329 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
7333 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7335 * symbols.c (local_label_name): symbols now start with ^A.
7337 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7338 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7339 generate these sections. .align: will use NOP_OPCODE or 0
7340 for padding. This is just for being nice to the
7343 * expr.c (operand): changed to generate local label "\001L0"
7344 starting with a ^A so that it is recognized as a local label.
7346 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7348 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7349 i/o opcodes - inb, inw, outb and outw. string manipulation with
7350 att syntax - scmp, slod, smov, ssca, ssto.
7352 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7353 to just after .file .
7355 In obj_crawl_symbol_chain() where it tries to put the external
7356 symbols apart, with the condition:
7357 (!S_IS_DEFINED(symbolP) &&
7358 !S_IS_DEBUG(symbolP) &&
7359 !SF_GET_STATICS(symbolP))
7360 it was moving too many symbols out. So I switch it back to the
7362 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7364 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7365 so that we don't use the F_RELFLG which make the linker complain
7366 that somebody has stripped the relocation info.
7368 Also, the AIX ld program require that the relocation table
7369 is sorted by r_vaddr like the standard ATT assembler does.
7371 [he also changed the sizeof(struct ...)'s into the coff
7372 style FOOSZ macros. I'm not sure this is right, but I can't
7373 remember why. xoxorich.]
7375 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
7377 * Makefile.in, configure.in, doc: use the doc. Build it, install
7380 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
7382 * read.c: white space and comments only.
7384 * configure.in: use the new atof-ns32.c for ns32k.
7386 * write.c: comment change only.
7388 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7389 aren't yet integrated.
7391 * tc-i860.[hc]: blew off the dust. Something must still be done
7392 about conflicting relocation types.
7394 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7397 * tc-i960.c, tc-sparc.c: white space and comments only.
7399 * tc-a29k.h: delete duplicate macro definition.
7401 * new file atof-ns32k.c copied from hack's last unreleased gas.
7403 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7405 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7408 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7409 ChangeLog's prior to this are sketchy at best. I have logs.
7410 They just aren't ChangeLogs.
7417 version-control: never
