  3596. symbol.
  3597. (print_expr_1): Fix whitespace before printing X_add_number.

  3633. always use vfprintf, because libiberty will provide it if the
  3634. native system doesn't. Also, always make format be const.
  3635. (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

  3639. (macro): Hack the -mips3 overflow tests to not fail when offsetT
  3640. is only 32 bits.
  3641. * symbols.h (copy_symbol_attributes): Declare.
  3642. Thu Sep 22 21:58:24 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

  3656. checking.
  3657. Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
  3658. * config/ho-*.h: Now-unused files deleted.
  3659. * symbols.c (copy_symbol_attributes): New function. Copies BFD
  3660. symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
  3661. (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
  3662. zero. Don't call obj_frob_forward_symbol.
  3663. * read.c (pseudo_set): Call copy_symbol_attributes, but only if
  3664. X_add_number is zero.
  3665. * config/obj-elf.h (obj_frob_forward_symbol): Deleted.

  3698. * configure.in: Test for remove, not delete. Fix cross-assembler
  3699. test.

  3701. remove, not delete.
  3702. * read.c (pseudo_set, case O_symbol): If
  3703. OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.

  3707. * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
  3708. many others): new macros; values obtained from "DSTRECRDS.SDL".
  3709. * config/obj-vms.h (various): use them.
  3710. (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
  3711. representation (only enum bitfields can avoid being bitstrings).
  3712. (bitfield_suffix, setup_basic_type): new routines.
  3713. (VMS_typedef_parse): use them. Now recognize bitfields of all
  3714. integral types, not just type `int'. Caveat: the representation
  3715. used for bitfields still does not work for objects placed in
  3716. registers, and gcc's optimizer sometimes puts small structs there.
  3717. Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
  3718. * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION

  3727. (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
  3728. and `gcc2_compiled.' labels; they won't reach here any more.
  3729. (VMS_typedef_parse) [case 'r']: for types `double' and `complex
  3730. double', use `vax_g_doubles' flag to select type of double.
  3731. (VMS_write_object_file) [traceback setup]: don't pass symbols
  3732. with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
  3733. and TBT_Routine_End functions.

  3736. S_GET_VALUE() to avoid many repeated function calls.

  3738. _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
  3739. gets requested. [All the HACK_DEC_C_STARTUP code appears to
  3740. be obsolete; gcc does it automatically for vms target. It's
  3741. also misnamed, because it is for the "VAX C" run-time library,
  3742. not the newer "DEC C" one which has much different startup code.]
  3743. {various}: use `S_SET_xxx(symbol,new_value)' rather than
  3744. `S_GET_xxx(symbol) = new_value'.

  3746. * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
  3747. not &bfd_abs_section.
  3748. Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
  3749. * expr.c (clean_up_expression): Use addressT, not bfd_vma.
  3750. Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
  3751. * expr.c (expr): Don't reduce the difference of two symbols in the
  3752. same frag if the symbols are not in normal sections.
  3753. * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.

  3757. (struct hppa_fix_struct): Delete fx_unwind field and all references.
  3758. (fix_new_hppa): Last arg is now a pointer to an int. Do not
  3759. call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
  3760. fixups, store 32bits of unwind information in the fx_addnumber
  3761. field of the fixup.
  3762. (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
  3763. and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
  3764. pointer to 32 bits of unwind info.
  3765. (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
  3766. pointer to the dummy symbol; set the addend field to fx_addnumber.
  3767. (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
  3768. rather than &bfd_XXX_section.
  3769. Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
  3770. * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
  3771. value by one; discard adjustments previously being made. From
  3772. Eric Youngdale.
  3773. VMS- and Vax-related changes from Pat Rankin:
  3774. * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
  3775. * vmsconf.sh: no longer have make-gas.com echo text about needing
  3776. to modify the gcc-vms driver when intending to use with gcc 1.x.
  3777. * as.c (parse_options): suppress 'v' from std_short_options and
  3778. eliminate VMS-specific conditional initialization;
  3779. [default case]: check for '-v' if md_parse_options doesn't recognize
  3780. an option;
  3781. [default case, #if VMS]: check for filename argument when '-v' seen;

  3783. * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
  3784. for O_big literal operands (double floats and long long ints);
  3785. [VMS, md_shortopts]: add second colon after 'v';
  3786. (md_parse_options) [VMS, case 'v']: check for argument, so
  3787. caller can handle `-v' w/o arg.
  3788. Tue Sep 13 16:45:08 1994 Steve Chamberlain (sac@jonny.cygnus.com)
  3789. * config/obj-coff.c (do_relocs_for): If TC_KEEP_FX_OFFSET

  5010. Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
  5011. * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
  5012. involving a function symbol which is not a plabel to zero.

  5022. to make it pcrel_offset.
  5023. (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
  5024. reloc->address; another gruesome hack to get gas reloc handling to
  5025. do the right thing.
  5026. Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

  5036. tested by code that might want to emit a LITUSE reloc.
  5037. (emit_unaligned_io): New function. Currently calls md_assemble,
  5038. but it should eventually be converted to generate the insn itself
  5039. and call emit_insn directly.

  5041. emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

  5067. (macro): Handle EMBEDDED_PIC in all PIC cases.
  5068. (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
  5069. OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
  5070. -non_shared to use NO_PIC (this is how the Irix 5 assembler
  5071. works). Do not permit -G with SVR4_PIC.
  5072. (s_abicalls): Warn if -G was used, and force -G 0.
  5073. (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
  5074. anything but a.out, not just for ELF. For ECOFF, don't generate a
  5075. BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
  5076. * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.

  5083. preprocessor directive to create a macro named by this value into
  5084. config.new; don't explicitly go for BFD_ASSEMBLER.
  5085. * configure.in: Define `defs', not `BFDDEF'. Set it to
  5086. MANY_SEGMENTS for any obj-coffbfd target.
  5087. * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
  5088. * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,

  5113. or not.
  5114. (adjust_reloc_syms): For now, always supply an absolute symbol for
  5115. fixups without symbols but not yet `done'. Use section_symbol to
  5116. get the symbol, instead of going directly for abs_symbol.
  5117. (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
  5118. reloc is not a section symbol and is not in the symbol table.
  5119. (set_symtab): New function, broken out from write_object_file.
  5120. Counts symbol table instead of relying on an earlier count.
  5121. (write_object_file): Call set_symtab, but do it after potentially
  5122. invoking the *_frob_file macros. Don't bother counting symbols.
  5123. Call symbol_remove, instead of expanding it in place. Moved the
  5124. conditionalized `object_file_size' declaration down to
  5125. conditionalized block where it's used. When using the absolute
  5126. symbol for a fixup without a symbol, set sy_used_in_reloc.
  5127. (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
  5128. the correct symbol for the absolute section.
  5129. * subsegs.c (section_symbol): Use symbol_new instead of
  5130. symbol_make, since we may want it to go into the symbol table.
  5131. Make the new symbol have internal linkage. If
  5132. obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
  5133. symbol with the newly created GAS symbol.
  5134. (obj_sec_sym_ok_for_reloc): Default to always returning 0.
  5135. * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

  5142. (sparc_ip, label "immediate"): Reject constants for pcrel
  5143. instructions only if the relocation type indicates a "call"
  5144. instruction and the offset is within range of a "jmpl %g0". If
  5145. it's not in range, use the absolute section symbol plus an offset.
  5146. (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
  5147. _BASE13 cases.
  5148. (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
  5149. * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
  5150. MANY_SEGMENTS).
  5151. * configure.in: Eliminated all targets using obj-coff but not
  5152. defining BFD_ASSEMBLER; I think all such targets that are
  5153. supported will be matched by real CPU-OS combinations earlier in
  5154. the case statement.
  5155. (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
  5156. some comments about the dpx2 configuration, but left it disabled,
  5157. since it couldn't be reached before.

  5164. the 'j' operand if there are no further alternatives for this
  5165. instruction.
  5166. * config/obj-coffbfd.c (adjust_stab_section): Initialize
  5167. stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
  5168. is not SEG_UNKNOWN rather than checking whether it is >= 0.
  5169. * config/tc-mips.c (mips_align): Take new argument, label, and use
  5170. it instead of global insn_label.
  5171. (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
  5172. call to mips_emit_delay and pass it to mips_align.

  5174. * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
  5175. * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an

  6850. Add comments to functions. Delete unused functions, variables,
  6851. #defines, etc. Delete unused members within structures. Delete

  6865. * config/tc-hppa.h (tc_fix_adjustable): New macro. Only accept relocations
  6866. which do not involve function symbols.
  6867. * config/tc-hppa.h: Reindent with GNU-indent. Delete references
  6868. to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused

  6871. * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
  6872. of elf32_symbol_type.
  6873. (pa_export_args): Likewise.
  6874. (elf_hppa_final_processing): Likewise.
  6875. (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed
  6876. anymore?)
  6877. (hppa_tc_make_sections): Do not declare elf_get_symtab_map any
  6878. ore.
  6879. * config/tc-hppa.c: (md_section_align): Align all sections to

  6881. multiple of 8.
  6882. * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
  6883. bits are zero (eg they specify no relocations), then do not even

  7721. * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
  7722. are also magic, and have special default flag settings.
  7723. (obj_elf_frob_symbol): Since the return value from this function
  7724. isn't used, don't bother calling obj_elf_write_symbol_p, since it
  7725. doesn't accomplish anything else.
  7726. * config/tc-sparc.c (md_section_align): Round up section size only
  7727. for a.out format.

  7737. poc_handler field.
  7738. * config/tc-h8500.c (md_begin): Use a local variable when

  7747. case to set obj_format=elf. Must go before i386-*-sysv* case that
  7748. sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
  7749. *-*-solaris case, and move to before *-sysv* case that wants to
  7750. set obj_format to coff.
  7751. * config/tc-i386.c (i386_operand): Change all 'exp.X_op' to

  7757. (obj_aout_frob_symbol): Set BSF_DEBUGGING for a constructor
  7758. symbol, so that BFD doesn't tamper with the type.
  7759. * read.c (read_a_source_file): If NO_PSEUDO_DOT is defined, look
  7760. up opcodes as pseudo-ops even if they don't start with '.'.

  7771. * Extensive changes to permit symbols to contain any expression
  7772. type and to delay the computation of the expression until the
  7773. value is actually needed. This permits setting symbols to values
  7774. calculated based on object code size. Expressions were changed to
  7775. no longer be in a section, to stop the overloading of segment and
  7776. expression type that previously occurred.
  7777. * as.c (big_section, pass1_section, diff_section, absent_section):

  7913. big and little endian targets.
  7914. (s_align, s_cons): Call mips_align rather than frag_align.

  7931. * config/tc-m88k.c (md_pcrel_from): Corrected return value.
  7932. (omagic): Removed unused variable.

  7945. TARGET_FORMAT.
  7946. (S_IS_LOCAL): Any symbol which includes \001 in the name is local.
  7947. * config/tc-m88k.c, config/tc-m88k.h: Numerous changes to bring
  7948. m88k port up to date, and to add COFF support.
  7949. Wed Jul 14 15:09:32 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

  7966. * config/obj-coffbfd.c (obj_coff_endef, yank_symbols): Check
  7967. expression segment rather than sy_forward.

  7989. * symbols.h: Compile S_{SG}ET_VALUE prototypes unconditionally.
  7990. * write.c (write_object_file): Set BFD symbol value to gas symbol

  8725. (obj_ecoff_stab): Accept non-zero values for stabs line number.

  8784. this directory.
  8785. (srcdir): Delete second, bogus definition.
  8786. (as.info): Look for as-*.texinfo in current directory rather than

  8807. * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
  8808. process relocs if there aren't any relocs to process. Avoids
  8809. malloc/free bug on SCO too.
  8810. * as.h: Move local include files below system include files, to
  8811. avoid some redefinition complaints on some systems.
  8812. (const, volatile): Don't need these conditionally defined if we
  8813. use CONST and VOLATILE from ansidecl.h.
  8814. (seg_name): Use CONST, not const.

  8818. * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
  8819. (fixup_segment): Add a29k special case; the linker is not prepared
  8820. to see a segment offset here.
  8821. * app.c (do_scrub_next_char): Added new state, 10, modifying state
  8822. 9 to only keep a space in between identifier characters.
  8823. Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
  8824. * Makefile.in: add dvi target; as-$(config).texinfo might live in
  8825. srcdir, might be in objdir.
  8826. * doc/Makefile.in: dvi depends on as.dvi
  8827. Mon Mar 22 23:59:13 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

  8841. * app.c (do_scrub_next_char): Added new state, 9, to avoid
  8842. dropping a space immediately following an identifier.
  8843. * expr.c, write.c: Rewrote assert expressions to not use multiple
  8844. lines; I don't think that can be done portably.
  8845. * config/tc-mips.c (macro): Use $AT if target register is zero in
  8846. load instruction, which it can be for a floating point load.
  8847. Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)
  8848. * write.c (write_contents): Compute the relocs before writing out

  8854. * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
  8855. by the section vma.
  8856. * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
  8857. z8k-opc.h, not z8k.h.
  8858. * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
  8859. symbol.
  8860. Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

  8880. (main): Call strdup instead.
  8881. * configure.in: Handle all 68300 series chips.
  8882. * config/tc-m68k.c: Include config.h.

  8899. * config/tc-mips.c: Rearranged for ECOFF support. Added
  8900. prototypes for all static functions. Moved existing minimal
  8901. debugging format support info #ifndef OBJ_ECOFF blocks.

  8933. * make-gas.com: Find obstack.obj if it's not in the current
  8934. directory.
  8935. * read.c (s_ignore): Don't declare is_end_of_line. It's
  8936. redundant, and triggers a VMS gcc compiler bug.
  8937. * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
  8938. current segment as an argument. (Ignored in all cases but VMS.)
  8939. All callers and definitions changed.
  8940. Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
  8941. * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING

  8943. Tue Mar 2 08:53:34 1993 Ken Raeburn (raeburn@cygnus.com)
  8944. * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,
  8945. so "~0x80" won't be rejected.
  8946. * config/obj-elf.c: No longer include elf/reloc.h.
  8947. (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
  8948. (obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out
  8949. routines.
  8950. (obj_elf_xstab): New routine.
  8951. (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
  8952. argument to s_ignore. Put "#if 0" around unused code.
  8953. (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
  8954. Call elf_xstabs for .stabs and .xstabs operators.
  8955. * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
  8956. * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
  8957. present.
  8958. * configure.in: mips-bsd configuration was missing format spec.
  8959. Should use aout.
  8960. * Makefile.in (Makefile): Depends on configure.in.
  8961. * config/tc-mips.c (append_insn): Don't check for alignment of
  8962. frag in memory; alignment of instructions in section is a separate
  8963. matter.
  8964. * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
  8965. C availability.

  9261. if these are used or defined, if BFD_ASSEMBLER.

  9285. * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
  9286. name rather than L0\001.
  9287. * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
  9288. local_bss_counter.
  9289. * symbols.c, symbols.h (local_bss_counter): Removed.
  9290. * write.c (write_object_file): bss no longer uses
  9291. local_bss_counter. Pass correct data and bss size to
  9292. VMS_write_object_file.
  9293. * config/obj-vms.c (VMS_write_object_file): Accept bss size as
  9294. argument, rather than using local_bss_counter.

  9297. * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
  9298. (size_section): Restored sanity check.
  9299. (do_relocs_for): Base section address on s_paddr rather than
  9300. computing it. Adjust a29k R_IHIHALF special case to account for
  9301. section paddr (used to require paddr to be zero). If there are no
  9302. reclos, set s_relptr to 0. Set relocation size in object_headers.
  9303. (fill_section): Always set s_vaddr here, removing
  9304. ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
  9305. NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
  9306. Set STYP_INFO for .comment.
  9307. (coff_header_append): Use object headers and H_{SET,GET}_* macros.
  9308. Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

  9310. H_{SET,GET}_* macros.
  9311. (do_linenos_for): Set lineno size in object_headers.
  9312. (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
  9313. set s_vaddr here. If string_byte_count remains 4, set it back to
  9314. 0, and only write strings out if there are some. Call
  9315. fill_section before do_relocs_for and do_linenos_for.
  9316. (obj_coff_section): Handle optional quoted second argument giving
  9317. section characteristics.
  9318. (obj_coff_bss): Added to handle .bss.
  9319. (obj_coff_ident): Added to handle .ident (puts string in .comment
  9320. section).
  9321. (obj_coff_lcomm): Put common symbols in .bss, not .data.
  9322. (fixup_mdeps): Change to segment. Call frag_wane after
  9323. md_convert_frag.
  9324. (fixup_segment): Explicitly check S_IS_COMMON before making 386
  9325. adjustment (already happened only for common symbols, but this is
  9326. clearer).

  9336. * app.c (app_push): Use memcpy, not bcopy.
  9337. (do_scrub_next_char): For \", return " not '.
  9338. (symbol_chars): Now const.
  9339. * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
  9340. and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
  9341. * config/obj-coff.h: Don't use #elif.
  9342. * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
  9343. have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
  9344. Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
  9345. * write.c, config/obj-ieee.c: don't define SUB_SEGMENT_ALIGN

  9348. * app.c (do_scrub_begin): allow single quote strings if so
  9349. configured.

  9361. (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
  9362. never set segment address for SEG_E2 (.bss) and don't write out
  9363. SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
  9364. (obj_coff_endef): Don't merge labels or symbols awaiting forward
  9365. definitions, and don't merge tags with non-tags. Check for .bf
  9366. rather than just checking whether the second character is b and
  9367. the third character is f.
  9368. (obj_coff_val): gcc can generate values which we don't handle
  9369. correctly; discard information for now, since it only affects the
  9370. debugging information.
  9371. (tag_find_or_name): Don't insert tags in the symbol table.
  9372. (yank_symbols): Don't merge labels.
  9373. (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
  9374. already defined. Fill subsegments with NOP_OPCODE, not 0. Don't
  9375. set segment address if ZERO_BASED_SEGMENTS.
  9376. (obj_coff_section): Accept and ignore a trailing quoted string, as
  9377. used in AT&T i386 syntax.
  9378. (fixup_segment): Take segment as argument. On the i386, adjust PC
  9379. relative addends by the segment vaddr.
  9380. * config/tc-i386.h: Define SUB_SEGMENT_ALIGN.
  9381. * config/tc-a29k.h: Define ZERO_BASED_SEGMENTS.

  9464. * configure.in: No te-386bsd.h file exists; don't try to use it.
  9465. * config/obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
  9466. * config/tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
  9467. could be doing emulation.
  9468. Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
  9469. z8000 documentation

  9523. (fill_section): Don't set STYP_NOLOAD for .bss section.
  9524. (fixup_segment): 386 uses strange common symbol format.
  9525. tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
  9526. compatibility with SVR3.2 linker.

  9547. * config/tc-i960.h, config/tc-i960.c: avoid the ANSI
  9548. preprocessor addition #elif, since it is not supported by old
  9549. compilers.
  9550. config/ho-rs6000.h, config/tc-m68k.c: the native RS/6000
  9551. compiler miscompiles a couple of expressions in tc-m68k.c.
  9552. Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
  9553. * read.c (cons): If NO_RELOC is defined, use it.

  9559. Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

  9567. Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
  9568. * config/obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
  9569. sections starting from zero, rather than making them consecutive.
  9570. This makes subsequent reloc calculations easier, esp if the object
  9571. format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
  9572. allocate lcomm in .data rather than in .bss. It seems that some
  9573. tools can't cope with a non-zero sized bss before linkage.

  9583. * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
  9584. Change LIBDEPS dependence to LIBS.

  9882. Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
  9883. * write.{c,h} (fix_new): Make these declarations consistent.
  9884. Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
  9885. * Makefile.in (strerror.o): Add rule so that broken Sun make can
  9886. work in subdirs.
  9887. Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
  9888. * read.c, obj-coffbfd.c : fix h8300 specific bit rot
  9889. * expr.c (operand): if can't work out what sort of operand it is,
  9890. then look through FLT_CHARS for a hint.
  9891. Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
  9892. * Makefile.in, configure.in: removed traces of namesubdir,
  9893. -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
  9894. copyrights to '92, changed some from Cygnus to FSF.
  9895. * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
  9896. -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
  9897. copyrights to '92, changed some from Cygnus to FSF.
  9898. Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
  9899. * expr.c: If an expression is single comma, then return with
  9900. SEG_ABSENT rather than an error - since the sparc front end does
  9901. really strange things with things like fbge,a
  9902. * as.h: include bfd.h if using many sections
  9903. * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
  9904. local labels didn't work.
  9905. * listing.c (list_symbol_table): don't core dump when there's no
  9906. symbol there.
  9907. * write.c, write.h: call fix_new with the right number of args on
  9908. the H8.
  9909. * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
  9910. errors nices
  9911. Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
  9912. * app.c: MRI compatibility - allow single quote to start a string.
  9913. * as.c: fix typo recently introduced.
  9914. * as.h : Don't include aout/reloc.h - it's not right for COFF!
  9915. * expr.c: Much rewriting, to accommodate MRI syntax for
  9916. expressions. Also easier to read now.
  9917. * listing.c: Put back defuns
  9918. * read.c: modified to accept MRI syntax, put back listing pseudo
  9919. ops so that an assembler built with NO_LISTING ignores list ops
  9920. rather than pukes.
  9921. * write.c, write.h: fixs - only keep a reloc type in a fix if the target
  9922. machine is a SPARC or a 29K.
  9923. * config/obj-aout.c: added s_sect pseudo op
  9924. * config/obj-coffbfd.c: lints, set the filehdr flags right and
  9925. fill in the timestamp.
  9926. * config/obj-coffbfd.h: Since we don't include aout/reloc.h
  9927. anymore, define all the relocs which the tc-<x> bit will use so we
  9928. can translate from them to the coff types.
  9929. * config/tc-a29k.c: reloc_type isn't ane enum any more
  9930. * config/tc-m68k.c: Added NO_RELOC definition.
  9931. Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
  9932. * Makefile.in: put header files before C source for TAGS; remove
  9933. references to non-existent syscalls.h.
  9934. * read.c, write.c subsegs.c: back out the .bss changes.
  9935. * config/obj-aout.c: do not include stab.gnu.h if NO_LISTING.
  9936. * config/tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
  9937. * a.out.h: removed.
  9938. Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
  9939. * symbols.c (local_label_name): symbols now start with ^A.
  9940. * read.c, subsegs.c, write.c obj-coff.c: added handling of
  9941. `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
  9942. generate these sections. .align: will use NOP_OPCODE or 0
  9943. for padding. This is just for being nice to the
  9944. disassembler.
  9945. * expr.c (operand): changed to generate local label "\001L0"
  9946. starting with a ^A so that it is recognized as a local label.
  9947. * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
  9948. * config/tc-i386.c: tc-i386.c: added handling of the following opcodes:
  9949. i/o opcodes - inb, inw, outb and outw. string manipulation with
  9950. att syntax - scmp, slod, smov, ssca, ssto.
  9951. * config/obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
  9952. to just after .file .
  9953. In obj_crawl_symbol_chain() where it tries to put the external
  9954. symbols apart, with the condition:
  9955. (!S_IS_DEFINED(symbolP) &&
  9956. !S_IS_DEBUG(symbolP) &&
  9957. !SF_GET_STATICS(symbolP))
  9958. it was moving too many symbols out. So I switch it back to the
  9959. condition:
  9960. (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
  9961. In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
  9962. so that we don't use the F_RELFLG which make the linker complain
  9963. that somebody has stripped the relocation info.
  9964. Also, the AIX ld program require that the relocation table
  9965. is sorted by r_vaddr like the standard ATT assembler does.
  9966. [he also changed the sizeof(struct ...)'s into the coff
  9967. style FOOSZ macros. I'm not sure this is right, but I can't
  9968. remember why. xoxorich.]
  9969. Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
  9970. * Makefile.in, configure.in, doc: use the doc. Build it, install
  9971. it, clean it, etc.
  9972. Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
  9973. * read.c: white space and comments only.
  9974. * configure.in: use the new atof-ns32.c for ns32k.
  9975. * write.c: comment change only.
  9976. * config/tc-m88k.[hc]: pulled in from hack's unfinished work. These
  9977. aren't yet integrated.
  9978. * config/tc-i860.[hc]: blew off the dust. Something must still be done
  9979. about conflicting relocation types.
  9980. * config/tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
  9981. real thing.
  9982. * config/tc-i960.c, config/tc-sparc.c: white space and comments only.
  9983. * config/tc-a29k.h: delete duplicate macro definition.
  9984. * new file atof-ns32k.c copied from hack's last unreleased gas.
  9985. Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
  9986. * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
  9987. rather than abort.
  9988. * nearly everything. flush ChangeLog, package as gas-1.92.1.
  9989. ChangeLog's prior to this are sketchy at best. I have logs.
  9990. They just aren't ChangeLogs.
