4463
4464         * config/tc-i386.c (i386_immediate): Move constant operand sizing
4465         from here..
4466         (md_assemble): To here, before template operands are matched.
4467         Also ensure a constant immediate is sign extended when we know the
4468         size is at most 16 bits.  This is to catch cases like "add
4469         $0xffc0,%ax" where we don't know the size, and thus that the
4470         immediate can be represented as Imm8S until after parsing the
4471         register operand.
4472         (i386_displacement): Similarly sign extend 16 bit constant
4473         displacements.
4474         (md_assemble): Relax 16-bit jump constant range check to suit sign
4475         extended displacements.

4489         (md_assemble): When determining suffix from Regs, exclude
4490         InOutPortReg.

4501
4502         * config/tc-arm.c (insns): Change displacement encoded in BL
4503         and B instructions if the target port is arm-wince.
4504         (do_ldst): Do not bias the relocation offset if the target
4505         port is arm-wince.
4506         (md_pcrel_from): Add in missing relocation offset bias if the
4507         target os arm-wince.

4523
4524         * config/tc-i386.c (md_assemble): Swap segments too for intel mode
4525         string instructions.
4526         (i386_operand_modifier): Set i.suffix = WORD_MNEM_SUFFIX for SHORT.
4527         (i386_intel_memory_operand): After finding a segment override,
4528         check again for no `[' before looking for a displacement.  Bomb if
4529         more than one displacement rather than silently discarding the
4530         second and subsequent ones.  Free strings malloc'd by
4531         build_displacement_string.
4532
4533 2000-02-24  Catherine Moore  <clm@cygnus.com>

4540         * config/tc-i386.c (union i386_op): New.
4541         (struct _i386_insn): Delete disps[], imms[], regs[].  Add op[].
4542         Throughout file replace occurences of disps[n], imms[n], regs[n]
4543         with equivalent op[n].disps, op[n].imms, op[n].regs.  Simplify
4544         intel mode operand swapping.  Add assert in regKludge and
4545         fake_zero_displacement code.  Test i.types[n] when outputting
4546         displacements and immediates.  Combine output of Disp16 with
4547         Disp32.
4548         (md_assemble): Don't try to fix broken UNIXWARE_COMPAT opcodes
4549         when in intel mode by (not) reversing fsub and fdiv operands
4550         before the template search.  This fails for single operand
4551         shorthand forms of the instruction, and if UNIXWARE_COMPAT is
4552         undefined.  Instead fix the base_opcode after we've found the
4553         template.  Move base_opcode xor with found_reverse_match from
4554         opcode output code to before this fix so we test for the correct
4555         opcodes.
4556         (md_assemble): Don't use strcmp when deciding to ignore the suffix
4557         check in intel mode.  Instead compare opcodes.
4558

4563         * as.h (flag_m68k_mri): Move declaration after target include, and
4564         only declare when TC_M68K defined.  Define as zero otherwise.
4565         (LABELS_WITHOUT_COLONS, NO_PSEUDO_DOT): If undefined, define as 0.
4566         * app.c (scrub_m68k_mri): Declare only when TC_M68K defined.

4574         * expr.c (operand): #ifdef unused case labels when TC_M68K undefined.
4575         * read.c: Use LABELS_WITHOUT_COLONS and NO_PSEUDO_DOT directly
4576         rather than testing whether defined.

4578         (parse_mri_cons): Declare and use only when TC_M68K.
4579         * config/tc-hppa.h (LABELS_WITHOUT_COLONS): Define as 1.
4580         * config/tc-m68k.h (NO_PSEUDO_DOT): Define as 1.
4581         * config/tc-m88k.h (NO_PSEUDO_DOT): Define as 1.

4711
4712         * read.c (read_a_source_file): If TC_START_LABEL_WITHOUT_COLON is
4713         defined, use it to verify the symbol just read should be a label.
4714
4715 2000-02-10  Timothy Wall  <twall@redhat.com>
4716
4717         * app.c (do_scrub_chars): Handle "||" for parallel instructions
4718         when DOUBLEBAR_PARALLEL is defined.  Avoid stripping whitespace
4719         around colons when KEEP_WHITE_AROUND_COLON is defined.
4720         * doc/internals.texi (CPU backend): Document DOUBLEBAR_PARALLEL
4721         and KEEP_WHITE_AROUND_COLON.
4722
4723 2000-02-08  Timothy Wall  <twall@redhat.com>
4724
4725         * read.c (s_rept): Call do_repeat, which abstracts the repeat
4726         logic.
4727         (do_repeat): New.  Abstract repeat logic so that a "break" can be
4728         implemented.
4729         (end_repeat): New.  Provide support for a "break" out of the
4730         repeat loop.
4731         * read.h: Add prototypes for new functions.
4732
4733 2000-02-08  Timothy Wall  <twall@redhat.com>
4734
4735         * doc/internals.texi: Document NUMBERS_WITH_SUFFIX macro.
4736         * as.h: Provide a default NUMBERS_WITH_SUFFIX definition (zero).
4737         * expr.c: Handle numbers with suffixes if NUMBERS_WITH_SUFFIX is
4738         non-zero.
4739
4740 2000-02-08  Timothy Wall  <twall@redhat.com>
4741
4742         * read.c: Added elseif to directives table.
4743         * read.h: Added prototype for s_elseif.
4744         * doc/as.texinfo: Added description for elseif.
4745         * cond.c (s_elseif): New function
4746

4750         listings.
4751
4752 2000-02-03  Timothy Wall  <twall@cygnus.com>
4753
4754         * as.h: Define OCTETS_PER_BYTE and OCTETS_PER_BYTE_POWER
4755         default values.
4756         * frags.c (frag_new): Calculate fr_fix in octets
4757         (frag_now_fix) Return offset as target address offset (bytes).
4758         (frag_now_fix_octets) New - Return offset in octets (8-bit
4759         quantities).
4760         * frags.h: Added prototype for frag_now_fix_octets().
4761         Distinguish between octets and bytes in field descriptions.
4762         * listing.c (calc_hex): Account for octets vs bytes when
4763         printing addresses/offsets.
4764         (print_lines) Ditto.  Also, if LISTING_WORD_SIZE is not 1, and
4765         target is little-endian, print the octets in a word in big-endian
4766         order so that the display looks like a proper hexadecimal number,
4767         instead of having the octets reversed.
4768         * read.c (do_align): When recording alignment, alignment power
4769         should be in terms of target bytes (minimum addressible unit)
4770         instead of octets.
4771         (do_org) Convert ORG target address (byte) argument into an
4772         octet offset when generating a variable fragment.
4773         * symbols.c (resolve_symbol_value): Symbol final value
4774         converted to a target address offset (bytes) from its octet offset.
4775         * config/obj-coff.c (coff_frob_symbol): Symbol target address
4776         offset (bytes) is adjusted by the frag offset (octets) converted
4777         to bytes.
4778         (coff_frob_section) Section alignment power is in terms of bytes;
4779         convert it to an octet alignment power when calculating size (and
4780         size mask) in octets.  Don't modify the section size in order to
4781         "align" it for TI COFF, since that format has a different method
4782         for storing alignment information.
4783
4784 2000-02-01  Timothy Wall  <twall@cygnus.com>
4785
4786         * stabs.c (generate_asm_file): Escape backslashes in stabs file
4787         entries, matching the way GCC generates them.  If not escaped, the
4788         filename is encoded incorrectly.
4789
4790 2000-01-31  Nick Clifton  <nickc@cygnus.com>
4791

4798         already defined.
4799         * config/tc-ppc.h [OBJ_XCOFF] (OBJ_COPY_SYMBOL_ATTRIBUTES):
4800         New macro.
4801         * config/tc-ppc.c (ppc_fix_adjustable): Don't look at the frag
4802         of a symbol when we really care about its value.
4803
4804 2000-01-19  Chandra Chavva   <cchavva@cygnus.com>
4805
4806         * config/tc-mcore.c (md_assemble): Give warning message if
4807         operands passes to instruction are more than the spec.
4808
4809 2000-01-27  Thomas de Lellis <tdel@windriver.com>
4810
4811         * config/tc-arm.c (armadjust_symtab): If the assembler is in
4812         Thumb mode but the label seen was not declared as '.thumb_func'
4813         then set the ST_INFO type to STT_ARM_16BIT mode.   This allows
4814         correct disassembly of Thumb code bounded by non function labels.

4822         Update copyright.
4823
4824         * configure.in: Set bfd_gas for i386-aout when primary target
4825         is bfd.  Handle i386aout emulation.  Don't use te_file=multi, as
4826         we may need the primary te_file.  Remove incorrect comment.
4827
4828         * configure: Regenerate.
