331 (control_regs): New pointer.
332 (m68k_ip): Use control_regs instead of testing CPU every time.

661 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
662 can be used within a label name.

696 all arguments have been processed.

779 directory, and specify PSECT attributes explicitly to linker.
780 Also added missing label.

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

965 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
966 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
967 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

982 (load_address): Handle EMBEDDED_PIC.
983 (macro): Handle EMBEDDED_PIC in all PIC cases.
984 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
985 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
986 -non_shared to use NO_PIC (this is how the Irix 5 assembler
987 works). Do not permit -G with SVR4_PIC.
988 (s_abicalls): Warn if -G was used, and force -G 0.
989 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for

1001 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1003 * Makefile.in (config-stamp): If `defs' is defined, emit a
1004 preprocessor directive to create a macro named by this value into
1005 config.new; don't explicitly go for BFD_ASSEMBLER.
1006 * configure.in: Define `defs', not `BFDDEF'. Set it to
1007 MANY_SEGMENTS for any obj-coffbfd target.
1008 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
1009 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
1011 (LOCAL_LOADLIBES): Deleted.
1012 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
1013 * config/m88kcoff.mt (TDEFINES): Ditto.

1039 bfd_set_symtab is called.
1040 (dump_section_relocs): Note whether a symbol is a section symbol
1042 (adjust_reloc_syms): For now, always supply an absolute symbol for
1043 fixups without symbols but not yet `done'. Use section_symbol to
1044 get the symbol, instead of going directly for abs_symbol.
1045 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
1046 reloc is not a section symbol and is not in the symbol table.
1047 (set_symtab): New function, broken out from write_object_file.
1048 Counts symbol table instead of relying on an earlier count.
1049 (write_object_file): Call set_symtab, but do it after potentially
1050 invoking the *_frob_file macros. Don't bother counting symbols.
1051 Call symbol_remove, instead of expanding it in place. Moved the
1052 conditionalized `object_file_size' declaration down to
1053 conditionalized block where it's used. When using the absolute
1054 symbol for a fixup without a symbol, set sy_used_in_reloc.
1055 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
1056 the correct symbol for the absolute section.
1058 * subsegs.c (section_symbol): Use symbol_new instead of
1059 symbol_make, since we may want it to go into the symbol table.
1060 Make the new symbol have internal linkage. If
1061 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
1062 symbol with the newly created GAS symbol.
1063 (obj_sec_sym_ok_for_reloc): Default to always returning 0.

1071 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
1072 (sparc_ip, label "immediate"): Reject constants for pcrel
1073 instructions only if the relocation type indicates a "call"
1074 instruction and the offset is within range of a "jmpl %g0". If
1075 it's not in range, use the absolute section symbol plus an offset.
1076 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
1078 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
1080 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
1083 * configure.in: Eliminated all targets using obj-coff but not
1084 defining BFD_ASSEMBLER; I think all such targets that are
1085 supported will be matched by real CPU-OS combinations earlier in
1087 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
1088 some comments about the dpx2 configuration, but left it disabled,
1089 since it couldn't be reached before.
1090 (target a29k-amd-ebmonold): Deleted.

1100 the 'j' operand if there are no further alternatives for this
1103 * config/obj-coffbfd.c (adjust_stab_section): Initialize
1104 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
1105 is not SEG_UNKNOWN rather than checking whether it is >= 0.
1107 * config/tc-mips.c (mips_align): Take new argument, label, and use
1108 it instead of global insn_label.
1109 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
1110 call to mips_emit_delay and pass it to mips_align.
1112 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1114 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
1116 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
1117 argument to a .callinfo directive. Don't loop forever on errors.

1125 S_IS_EXTERNAL when deciding whether to discard a symbol.
1127 * config-gas.com: Scan Makefile.in, not version.c, for current
1128 version number. Delete all versions of temp files when finished
1129 with them. Create config.h.

1132 values to reduce number of lookups with S_GET_VALUE. Skip debug
1133 symbols to avoid "a really nasty bug". (From Holger Teutsch,
1134 holger@botbso.rhein-main.de.)
1135 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
1136 field. (Also from Holger Teutsch.) Watch for a would-be register
1137 mask that spans frags.
1139 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
1140 this_base, not line_base. (Patch from Andreas Arens,

1144 look local if they're exported or undefined. Used to be done for
1147 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

1151 (lex_type): Use it for `%'.
1153 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

3292 * read.c (next_char_of_string): Limit octal character constants to
3295 * config/tc-hppa.h: Major cleanup. Use GNU-style comments. Warn
3296 against placing additional object-file dependent code here. Warn
3297 against contaminating all of GAS with the internals of tc-hppa.c
3298 through inclusion of tc-hppa.h. Delete all forward declarations
3299 for functions only used within tc-hppa.c, likewise for structures,
3300 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
3301 conditional code in a few small places.
3303 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3304 structures, global variables, forward declarations together.

3306 conditional code -- try to group conditional code together
3307 into a few places. Make all functions and variables which
3308 are only used within tc-hppa.c static. PARAMize all functions.
3309 Add comments to functions. Delete unused functions, variables,
3310 #defines, etc. Delete unused members within structures. Delete
3311 ldil;ble hacks -- it is believed they were installed to work
3312 around old gas bugs. Avoid using mixed case for local
3313 functions, variables, and structures. Fix formatting problems
3314 not found by GNU-indent. Add FIXME notices for things which
3315 should be worked on the near future. Delete lots of old
3316 useless (1.36 PA-SOM) code.
3318 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
3319 field of the fixS structure. Needed to build unwind
3320 descriptors correctly.

3345 a multiple of the section alignment rather than always a
3348 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
3349 bits are zero (eg they specify no relocations), then do not even
3350 bother adding their entries to thesymextn section.

5787 a29k .bss section; the mondfe program doesn't like it.

5808 source directory, if that's not the current directory.
5810 * configure.in (per-host): Accept MIPS host with BSD version

5832 process relocs if there aren't any relocs to process. Avoids
5833 malloc/free bug on SCO too.

5836 avoid some redefinition complaints on some systems.
5837 (const, volatile): Don't need these conditionally defined if we
5838 use CONST and VOLATILE from ansidecl.h.
5839 (seg_name): Use CONST, not const.
5841 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5843 * config/tc-mips.c: Reindented to GNU standards.
5845 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
5847 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5848 (fixup_segment): Add a29k special case; the linker is not prepared
5849 to see a segment offset here.
5851 * app.c (do_scrub_next_char): Added new state, 10, modifying state
5852 9 to only keep a space in between identifier characters.
5854 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5856 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5857 srcdir, might be in objdir.
5859 * doc/Makefile.in: dvi depends on as.dvi

5877 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
5878 bignums, but don't emit error message.
5880 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
5882 * Makefile.in (targ-cpu.o): Depend on config.h.
5884 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5886 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5887 dropping a space immediately following an identifier.
5888 * expr.c, write.c: Rewrote assert expressions to not use multiple
5889 lines; I don't think that can be done portably.
5890 * config/tc-mips.c (macro): Use $AT if target register is zero in
5891 load instruction, which it can be for a floating point load.
5893 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5904 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
5905 z8k-opc.h, not z8k.h.
5907 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
5910 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

5961 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.

5965 prototypes for all static functions. Moved existing minimal
5966 debugging format support info #ifndef OBJ_ECOFF blocks.

5969 all callers accordingly.
5970 (tc_get_register): Renamed from get_register, and made non-static.

6015 * make-gas.com: Find obstack.obj if it's not in the current
6017 * read.c (s_ignore): Don't declare is_end_of_line. It's
6018 redundant, and triggers a VMS gcc compiler bug.
6020 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
6021 current segment as an argument. (Ignored in all cases but VMS.)
6022 All callers and definitions changed.

6040 argument to s_ignore. Put "#if 0" around unused code.
6041 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
6042 Call elf_xstabs for .stabs and .xstabs operators.
6044 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
6046 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
6049 * configure.in: mips-bsd configuration was missing format spec.
6052 * Makefile.in (Makefile): Depends on configure.in.
6054 * config/tc-mips.c (append_insn): Don't check for alignment of
6055 frag in memory; alignment of instructions in section is a separate

6075 * config/tc-sparc.c (s_xword): Now call big_cons, so large
6076 constants are accepted, but symbolic values are not. GCC will not
6077 generate the latter currently.
6079 * frags.c (frag_init): New function.
6080 (zero_address_frag, bss_address_frag): Now initialized at run
6082 * as.c (main): Call frag_init.

6349 * expr.c (operand): If character other than comma or newline is a
6350 logical end-of-line character, use the newline case.

6352 (operand): Set X_add_number field for floating-point numbers.
6353 (operand): Treat zero byte as end-of-operand.
6355 * configure.in (per-target): Look for with_bfd_assembler option.
6356 For now, only accept "no", until the merge is done.
6358 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):

6368 md_[long,short]_jump_size. Remove declaration of const_flag
6369 (which will be declared in obj-vms.h).
6370 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6371 Fix arguments to VMS_write_object_file.
6372 * config-gas.com: New file. Script for VMS systems to set up the

6381 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6382 types of malformed stabs. Change parsing algorithm so that we are
6383 more certain of having all of the information that we need on hand.
6384 * obj-vms.c (final_forward_reference): New function, used to help
6385 resolve the data types of as many struct elements as possible

6403 SEG_DATA or SEG_E1 if needed.
6404 (s_lcomm): Likewise with bss_section.
6405 (s_fill): Use memset, not bzero.

6434 if these are used or defined, if BFD_ASSEMBLER.
6435 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6436 subseg_new split into two functions.
6437 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6439 * as.h (volatile): Don't define if already defined.
6440 (had_errors, had_warnings): Provide prototypes for ANSI C even if

6460 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6461 (DOT_LABEL_PREFIX): Define.

6475 (size_section): Restored sanity check.
6476 (do_relocs_for): Base section address on s_paddr rather than
6477 computing it. Adjust a29k R_IHIHALF special case to account for

6479 reclos, set s_relptr to 0. Set relocation size in object_headers.
6480 (fill_section): Always set s_vaddr here, removing
6481 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6482 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6483 Set STYP_INFO for .comment.

6487 H_{SET,GET}_* macros.
6488 (do_linenos_for): Set lineno size in object_headers.
6489 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6490 set s_vaddr here. If string_byte_count remains 4, set it back to
6491 0, and only write strings out if there are some. Call
6492 fill_section before do_relocs_for and do_linenos_for.
6493 (obj_coff_section): Handle optional quoted second argument giving
6494 section characteristics.
6495 (obj_coff_bss): Added to handle .bss.
6496 (obj_coff_ident): Added to handle .ident (puts string in .comment

6520 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6522 * config/obj-coff.h: Don't use #elif.
6524 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6525 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
6527 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
6529 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

6545 * listing.c: Call xmalloc, not malloc; don't declare malloc.
6547 * Changes to support SCO 3.2v4:
6548 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
6549 SEG_BSS, fill with NOP_OPCODE.
6550 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
6551 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6552 using ZERO_BASED_SEGMENTS.
6553 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6554 never set segment address for SEG_E2 (.bss) and don't write out
6555 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6556 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6557 definitions, and don't merge tags with non-tags. Check for .bf
6558 rather than just checking whether the second character is b and
6559 the third character is f.
6560 (obj_coff_val): gcc can generate values which we don't handle
6561 correctly; discard information for now, since it only affects the
6562 debugging information.
6563 (tag_find_or_name): Don't insert tags in the symbol table.
6564 (yank_symbols): Don't merge labels.
6565 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
6566 already defined. Fill subsegments with NOP_OPCODE, not 0. Don't
6567 set segment address if ZERO_BASED_SEGMENTS.
6568 (obj_coff_section): Accept and ignore a trailing quoted string, as
6569 used in AT&T i386 syntax.
6570 (fixup_segment): Take segment as argument. On the i386, adjust PC
6571 relative addends by the segment vaddr.
6572 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
6573 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
6574 * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

6675 xrealloc from xrealloc.c.
6676 * xrealloc.c: Deleted.
6677 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
6679 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
6682 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
6684 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;

6703 * all files: Whitespace changes for GNU indentation style, done by
6704 GNU `indent'. Some cleanup still needed, especially of comments.
6706 * configure.in: No te-386bsd.h file exists; don't try to use it.

6710 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
6711 could be doing emulation.
6713 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6716 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
6719 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
6721 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

6743 consistently const, and always initialized them. Included read.h.
6745 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6747 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6748 constant will not fit in an immediate field.
6749 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

6784 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6786 * Support for i386-sysv.
6787 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6791 (fill_section): Don't set STYP_NOLOAD for .bss section.
6792 (fixup_segment): 386 uses strange common symbol format.

6806 fix i960+non-bfd coff bit rot.
6807 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
6808 support for C source listings. (obj_coff_endef): look in the right

6825 * tc-z8k.c: lots of bug fixes
6827 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6829 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6830 #elif, since it is not supported by old compilers.
6831 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6832 couple of expressions in tc-m68k.c.
6834 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6836 * read.c (cons): If NO_RELOC is defined, use it.
6838 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6840 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6842 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6843 local labels to start with a .) and set REGISTER_PREFIX to %.
6844 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6846 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

6860 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6862 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6863 sections starting from zero, rather than making them consecutive.
6864 This makes subsequent reloc calculations easier, esp if the object
6865 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6866 allocate lcomm in .data rather than in .bss. It seems that some
6867 tools can't cope with a non-zero sized bss before linkage.
6869 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6871 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6872 throughout. That enum no longer means what we thought it meant.

6875 "-mno-688[58]1" options.
6877 * tc-m68k.c: Added CPU32 support.

6885 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
6886 Change LIBDEPS dependence to LIBS.
6888 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6890 * Makefile.in (install): if $(tooldir) exists, install as in
6893 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6895 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6896 .word is < -32768 or > 32767. The -J flag causes the error to be
6897 ignored. This is to catch over-sized switches generated by gcc on
6898 systems which don't support the broken .word hack.
6899 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6900 write.c (fixup_segment): check for signed .word overflow if
6901 WARN_SIGNED_OVERFLOW_WORD.
6903 * write.c (fixup_segment): fixed missing parens in expression
6904 checking for byte or word overflow.
6906 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
6907 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
6908 WARN_SIGNED_OVERFLOW_WORD.

6916 * obj-coffbfd.h : added stuff
6917 * tc-i386.c (tc_coff_fix2rtype): new function
6918 * tc-i386.h : new coff defines
6920 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6922 * input-scrub.c (input_scrub_push): call input_file_begin, not
6924 messages.c (as_perror): print ": " between the passed in error and
6925 the strerror, like perror does.
6927 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6929 * Makefile.in: use gas_target instead of modifying target_cpu.
6930 From Steve Chamberlain:
6931 Makefile.in: Handle m68*-*-coff*.
6932 read.c, read.h: add mult argument to s_space
6934 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6935 Motorola and MIT syntax; gas can now assemble either type of
6937 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
6938 From Steve Chamberlain:
6939 m68kcoff.mt: for m68k COFF.
6940 obj-coffbfd.c: (fixup_mdeps) added
6941 (size_section) removed bad sanity check
6942 (fill_section) added rs_machine_dependent case
6943 (write_object_file) call fixup_mdeps
6944 (fixup_segment) set fx_subsy to 0.
6945 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6947 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6950 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6952 * Makefile.in (LIBS): Include opcode library.
6954 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
6956 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
6957 including zero are accepted, pass +0.0.

6961 * Makefile.in: map "as" through program_transform_name when
6964 * doc/Makefile.in: map "as" through program_transform_name when
6967 Sat Aug 29 12:11:12 1992 Jim Wilson (wilson@sphagnum.cygnus.com)

6974 tc-i960.c (md_ri_to_chars): Always output bout object file in
6975 little endian byte order (used to use endianness of host).
6977 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6979 * config/tc-m68k.c (init_table): Now const. Always include 68851
6980 data, so that "bc" is available to 68040 cache instructions.
6981 Added "tt0", "tt1", and 68ec030 variants.
6982 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6983 (enum _register): Added TT0, TT1.
6984 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6985 line number correctly in "internal error" messages. Don't print
6986 architecture-mismatch message for operand errors.
6988 From Colin Smith (colin@wrs.com):
6989 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6990 than install_operand.
6992 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6994 * listing.c (buffer_line): rewind to the start of include
6995 files, they might be included twice.
6997 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
6999 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
7001 * Makefile.in: defined TARGET_CPU for C code so that it can choose
7002 one element of a family.
7004 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
7006 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
7007 so that we can assemble hand-written libgcc code.
7009 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7011 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
7012 has already been formatted (but may still contain %-characters).
7015 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
7017 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
7018 written with indirection on the last two operands, which can be
7019 either data or address registers. Added a new operand type 'r'
7020 which accepts either register type. Added '(' to notend stuff in
7021 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
7023 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
7025 * as.h (enum _relax_state): Start off at one, not zero, to better
7026 catch uninitialized-variable errors.

7034 data_last_frag): No longer static.
7035 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
7036 defined, call it. Change segments before calling fixup_segment.
7037 (relax_align): If linkrelax, provide extra padding.

7270 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
7272 * Makefile.in (install): Install into $(tooldir)/bin, since that's
7273 where gcc looks for it.
7275 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
7277 * Makefile.in: Changed some lines to be less confusing for some

7347 * expr.c (operand): if can't work out what sort of operand it is,
7348 then look through FLT_CHARS for a hint.
7350 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
7352 * Makefile.in, configure.in: removed traces of namesubdir,

7356 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
7357 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
7358 copyrights to '92, changed some from Cygnus to FSF.
7360 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7362 * expr.c: If an expression is single comma, then return with
7363 SEG_ABSENT rather than an error - since the sparc front end does
7364 really strange things with things like fbge,a
7366 * as.h: include bfd.h if using many sections
7367 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
7368 local labels didn't work.
7369 * listing.c (list_symbol_table): don't core dump when there's no
7371 * write.c, write.h: call fix_new with the right number of args on
7373 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
7376 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7378 * app.c: MRI compatibility - allow single quote to start a string.
7379 * as.c: fix typo recently introduced.
7380 * as.h : Don't include aout/reloc.h - it's not right for COFF!
7381 * expr.c: Much rewriting, to accomodate MRI syntax for
7382 expressions. Also easier to read now.
7383 * listing.c: Put back defuns
7384 * read.c: modified to accept MRI syntax, put back listing pseudo
7385 ops so that an assembler built with NO_LISTING ignores list ops
7387 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7388 machine is a SPARC or a 29K.
7389 * config/obj-aout.c: added s_sect pseudo op
7390 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7391 fill in the timestamp.
7392 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7393 anymore, define all the relocs which the tc-<x> bit will use so we
7394 can translate from them to the coff types.
7395 * config/tc-a29k.c: reloc_type isn't ane enum any more
7396 * config/tc-m68k.c: Added NO_RELOC definition.
7398 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
7400 * Makefile.in: put header files before C source for TAGS; remove
7401 references to non-existent syscalls.h.
7403 * read.c, write.c subsegs.c: back out the .bss changes.
7405 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7407 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
7411 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7413 * symbols.c (local_label_name): symbols now start with ^A.
7415 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7416 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7417 generate these sections. .align: will use NOP_OPCODE or 0
7418 for padding. This is just for being nice to the
7421 * expr.c (operand): changed to generate local label "\001L0"
7422 starting with a ^A so that it is recognized as a local label.
7424 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7426 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7427 i/o opcodes - inb, inw, outb and outw. string manipulation with
7428 att syntax - scmp, slod, smov, ssca, ssto.
7430 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7431 to just after .file .
7433 In obj_crawl_symbol_chain() where it tries to put the external
7434 symbols apart, with the condition:
7435 (!S_IS_DEFINED(symbolP) &&
7436 !S_IS_DEBUG(symbolP) &&
7437 !SF_GET_STATICS(symbolP))
7438 it was moving too many symbols out. So I switch it back to the
7440 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7442 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7443 so that we don't use the F_RELFLG which make the linker complain
7444 that somebody has stripped the relocation info.
7446 Also, the AIX ld program require that the relocation table
7447 is sorted by r_vaddr like the standard ATT assembler does.
7449 [he also changed the sizeof(struct ...)'s into the coff
7450 style FOOSZ macros. I'm not sure this is right, but I can't
7451 remember why. xoxorich.]
7453 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
7455 * Makefile.in, configure.in, doc: use the doc. Build it, install

7460 * read.c: white space and comments only.
7462 * configure.in: use the new atof-ns32.c for ns32k.
7464 * write.c: comment change only.
7466 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7467 aren't yet integrated.
7469 * tc-i860.[hc]: blew off the dust. Something must still be done
7470 about conflicting relocation types.
7472 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7475 * tc-i960.c, tc-sparc.c: white space and comments only.
7477 * tc-a29k.h: delete duplicate macro definition.
7479 * new file atof-ns32k.c copied from hack's last unreleased gas.
7481 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7483 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7486 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7487 ChangeLog's prior to this are sketchy at best. I have logs.
7488 They just aren't ChangeLogs.
7495 version-control: never
