620 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
621 not symbol_new, for symbols holding expression values.
622 * expr.h (make_expr_symbol): Move declaration here.
623 * write.c (fix_new_exp): Handle O_add by creating an
624 expression-valued symbol, and calling fix_new_exp recursively.
625 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
626 undefined symbol and a constant, fold the constant into the fixup,
627 and refer to the undefined symbol directly. Then process the
628 fixup again from scratch.
629 (write_object_file): Before calling adjust_reloc_syms, make a pass
630 through the symbol list trying to resolve values.
632 * write.c (print_fixup): New routine, for debugging.
633 (write_relocs): Call bfd_install_relocation. Deleted various
634 hacks for working around problems with bfd_perform_relocation.

651 * write.c (write_relocs): Add file name and line number to
652 as_fatal calls. Handle bfd_reloc_overflow case specifically when
653 RELOC_EXPANSION_POSSIBLE.
655 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
657 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
658 here. Use them for deciding which PRINTF*LIKE macro definitions
660 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
661 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
662 default definitions matching what we were doing before.
663 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
664 always use the varargs form if not using stdarg. It's safe to
665 always use vfprintf, because libiberty will provide it if the
666 native system doesn't. Also, always make format be const.
667 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

685 false (if defined) as well as checking for reg_section.
686 (listing_listing): Iterate fetching lines while line number is too
687 low, and we haven't run off the end of the input file.
689 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.

718 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
720 * config/vms-conf.h: new file, manually derived from conf.in.
721 * config-gas.com: use it, and eliminate obsolete "host.h".

732 from the csect of the enclosing block.
734 * config/tc-mips.c (insns_since_cache_access): Remove.

740 * config/tc-mips.c (md_shortopts): Remove E.
741 (md_longopts): Add EB and EL.
742 (md_parse_option): Handle -EB and -EL as separate options, rather

745 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
747 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
748 involving global symbols too.
750 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
752 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
754 * configure.in: Test for remove, not delete. Fix cross-assembler

766 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
767 many others): new macros; values obtained from "DSTRECRDS.SDL".
768 * config/obj-vms.h (various): use them.
769 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
770 representation (only enum bitfields can avoid being bitstrings).
771 (bitfield_suffix, setup_basic_type): new routines.
772 (VMS_typedef_parse): use them. Now recognize bitfields of all
773 integral types, not just type `int'. Caveat: the representation
774 used for bitfields still does not work for objects placed in
775 registers, and gcc's optimizer sometimes puts small structs there.
777 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
779 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
781 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
782 (tc_frob_label): define this to call vms_check_for_special_label,
783 and declare the latter.

786 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.

788 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
789 and `gcc2_compiled.' labels; they won't reach here any more.
790 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
791 double', use `vax_g_doubles' flag to select type of double.
792 (VMS_write_object_file) [traceback setup]: don't pass symbols
793 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
794 and TBT_Routine_End functions.
796 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
798 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
799 S_GET_VALUE() to avoid many repeated function calls.
800 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
801 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
802 gets requested. [All the HACK_DEC_C_STARTUP code appears to
803 be obsolete; gcc does it automatically for vms target. It's
804 also misnamed, because it is for the "VAX C" run-time library,
805 not the newer "DEC C" one which has much different startup code.]
806 {various}: use `S_SET_xxx(symbol,new_value)' rather than
807 `S_GET_xxx(symbol) = new_value'.

811 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,

816 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
818 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
820 * expr.c (expr): Don't reduce the difference of two symbols in the
821 same frag if the symbols are not in normal sections.
823 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
824 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
825 (obj_attach_unwind_info): Do not define. Not needed anymore.
826 * config/tc-hppa.c: Delete whitespace at EOL.
827 (struct hppa_fix_struct): Delete fx_unwind field and all references.
828 (fix_new_hppa): Last arg is now a pointer to an int. Do not
829 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
830 fixups, store 32bits of unwind information in the fx_addnumber
832 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
833 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
834 pointer to 32 bits of unwind info.
835 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
836 pointer to the dummy symbol; set the addend field to fx_addnumber.
837 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
838 rather than &bfd_XXX_section.
840 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
842 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
843 value by one; discard adjustments previously being made. From
846 VMS- and Vax-related changes from Pat Rankin:
847 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
848 * vmsconf.sh: no longer have make-gas.com echo text about needing
849 to modify the gcc-vms driver when intending to use with gcc 1.x.
850 * as.c (parse_options): suppress 'v' from std_short_options and
851 eliminate VMS-specific conditional initialization;
852 [default case]: check for '-v' if md_parse_options doesn't recognize

856 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
857 for O_big literal operands (double floats and long long ints);
858 [VMS, md_shortopts]: add second colon after 'v';
859 (md_parse_options) [VMS, case 'v']: check for argument, so
860 caller can handle `-v' w/o arg.

912 * gdbinit.in: New file, created from old .gdbinit.
914 * aclocal.m4 (GAS_GDBINIT): Deleted.
915 * configure.in: Don't use it. Instead, generate .gdbinit from
916 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
917 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
918 to ensure that older versions of autoconf aren't used.

1985 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
1986 for gcc2's predefined types "long double" (same as double, as

2353 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2355 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2357 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2358 source files from other directories into objects in the current
2359 directory, and specify PSECT attributes explicitly to linker.
2360 Also added missing label.
2361 * Makefile.in (stamp-mk.com): Reference new variable

2379 argument, the reloc type.
2380 (load_register): Pass reloc type to macro_build for 'u'.
2381 (macro): Likewise. For M_LA_AB permit a difference expression
2382 when generating embedded PIC code between an arbitrary symbol and
2383 a symbol in the .text section.
2384 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
2385 BFD_RELOC_PCREL_LO16 to be emitted.

2393 * subsegs.c (subsegs_begin): Call memset with args in the correct
2395 (subseg_get): Clear newly allocated seginfo, set its pointer slots
2396 to NULL instead of 0.

2400 * config/tc-hppa.c (pa_procend): Handle case where label was
2401 defined after the .proc directive.
2403 * config/tc-hppa.c (pa_procend): Give an error if we encounter a

2425 (hppa_tc_symbol): Likewise.
2427 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2428 elf_tc_make_sections stuff. It was there to support PA braindamage
2429 which has been fixed, and in the case of elf_tc_make_sections is
2430 redundant with elf_tc_final_processing.

2450 don't spew remainder of input file in error message.
2451 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2452 message with reloc type and try to process remainder of file.
2454 * doc/Makefile.in (install-info-as, install-info-gasp): New
2455 targets, now explicitly checking $(srcdir) for info files.
2456 (install-info): Depend on both of them; do nothing more.

2464 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2465 flag rather than signedp field. Only permit extended range if
2466 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2467 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2469 * config/tc-ppc.c (ppc_size): New static variable.
2470 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2471 (md_begin): If an instruction has a size specific flag set, only
2472 add it if we are assembling that size.

2476 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2477 cross section PC relative relocs right for COFF and ELF.
2479 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2481 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

2486 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
2487 the type of symbol set symbols which happen to be in the absolute
2488 or undefined section.

2492 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2493 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2494 and -many (all architectures).

2504 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2505 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2507 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2508 branch with an instruction that uses $at, in case the branch is
2510 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2511 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2512 to make it pcrel_offset.
2513 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2514 reloc->address; another gruesome hack to get gas reloc handling to
2517 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2519 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2522 (emit_insn): New function.
2523 (md_assemble): Call it.
2524 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2526 (lituse_pending): New variable. Set by anything that generates a
2527 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2528 tested by code that might want to emit a LITUSE reloc.
2529 (emit_unaligned_io): New function. Currently calls md_assemble,
2530 but it should eventually be converted to generate the insn itself
2531 and call emit_insn directly.
2532 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2533 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2534 emit_bis_r): Likewise.
2535 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2536 (alpha_ip, label get_macro): Don't emit the final instruction if
2538 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2539 unaligned memory access macros.
2540 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
2541 the value can't be resolved.
2543 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2545 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2546 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2547 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

2559 * config/tc-mips.c (enum mips_pic_level): New enum.
2560 (mips_pic): Change from int to enum mips_pic_level. Change all
2561 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2562 (load_address): Handle EMBEDDED_PIC.
2563 (macro): Handle EMBEDDED_PIC in all PIC cases.
2564 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2565 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2566 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2567 works). Do not permit -G with SVR4_PIC.
2568 (s_abicalls): Warn if -G was used, and force -G 0.
2569 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2570 anything but a.out, not just for ELF. For ECOFF, don't generate a
2571 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2573 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2575 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2577 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2578 parameters to avoid losing when compiling with HP CC.
2579 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2581 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2583 * Makefile.in (config-stamp): If `defs' is defined, emit a
2584 preprocessor directive to create a macro named by this value into
2585 config.new; don't explicitly go for BFD_ASSEMBLER.
2586 * configure.in: Define `defs', not `BFDDEF'. Set it to
2587 MANY_SEGMENTS for any obj-coffbfd target.
2588 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2589 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2591 (LOCAL_LOADLIBES): Deleted.
2592 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2593 * config/m88kcoff.mt (TDEFINES): Ditto.

2619 bfd_set_symtab is called.
2620 (dump_section_relocs): Note whether a symbol is a section symbol
2622 (adjust_reloc_syms): For now, always supply an absolute symbol for
2623 fixups without symbols but not yet `done'. Use section_symbol to
2624 get the symbol, instead of going directly for abs_symbol.
2625 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2626 reloc is not a section symbol and is not in the symbol table.
2627 (set_symtab): New function, broken out from write_object_file.
2628 Counts symbol table instead of relying on an earlier count.
2629 (write_object_file): Call set_symtab, but do it after potentially
2630 invoking the *_frob_file macros. Don't bother counting symbols.
2631 Call symbol_remove, instead of expanding it in place. Moved the
2632 conditionalized `object_file_size' declaration down to
2633 conditionalized block where it's used. When using the absolute
2634 symbol for a fixup without a symbol, set sy_used_in_reloc.
2635 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2636 the correct symbol for the absolute section.
2638 * subsegs.c (section_symbol): Use symbol_new instead of
2639 symbol_make, since we may want it to go into the symbol table.
2640 Make the new symbol have internal linkage. If
2641 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2642 symbol with the newly created GAS symbol.
2643 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2644 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2651 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2652 (sparc_ip, label "immediate"): Reject constants for pcrel
2653 instructions only if the relocation type indicates a "call"
2654 instruction and the offset is within range of a "jmpl %g0". If
2655 it's not in range, use the absolute section symbol plus an offset.
2656 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2658 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2660 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2663 * configure.in: Eliminated all targets using obj-coff but not
2664 defining BFD_ASSEMBLER; I think all such targets that are
2665 supported will be matched by real CPU-OS combinations earlier in
2667 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2668 some comments about the dpx2 configuration, but left it disabled,
2669 since it couldn't be reached before.
2670 (target a29k-amd-ebmonold): Deleted.
2672 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2680 the 'j' operand if there are no further alternatives for this
2683 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2684 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2685 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2687 * config/tc-mips.c (mips_align): Take new argument, label, and use
2688 it instead of global insn_label.
2689 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2690 call to mips_emit_delay and pass it to mips_align.
2692 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2694 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2696 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2697 argument to a .callinfo directive. Don't loop forever on errors.
2699 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2700 use pre-defined registers as arguments.

2705 S_IS_EXTERNAL when deciding whether to discard a symbol.
2707 * config-gas.com: Scan Makefile.in, not version.c, for current

2709 with them. Create config.h.
2711 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2712 values to reduce number of lookups with S_GET_VALUE. Skip debug
2713 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2714 holger@botbso.rhein-main.de.)
2715 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2716 field. (Also from Holger Teutsch.) Watch for a would-be register
2717 mask that spans frags.
2719 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2720 this_base, not line_base. (Patch from Andreas Arens,

2723 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2724 look local if they're exported or undefined. Used to be done for
2727 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2728 Get it from the looked-up symbol, instead of using the string from
2729 the input stream, which is no longer null-terminated.
2730 (LEX_PCT): New macro, defaults to 0.
2731 (lex_type): Use it for `%'.
2733 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

2783 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2784 0xffff for 'j' to be compatible with MIPS assembler. These
2785 numbers are actually treated as negative.

2796 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this
2797 work. It still doesn't. It now fails to compile, instead of
2798 silently compiling to do nothing.
2799 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define only if
2801 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

4368 Delete dead code. Simplify.
4369 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
4370 applied are in range. Use bfd_put_32 rather than inserting each

4485 of interest to the linker. ENTRY/EXIT relocations for SOM are
4486 an example of marker relocations.
4487 * write.c (write_relocs): Instead of assuming size of a relocation
4488 is 4 bytes, pick up the size from relocation itself.

4740 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
4741 the table, require that the one without bit 0x1000000 set come
4742 first. Require further that it be case 'b' or 'P'. The a29k
4743 opcode table already meets these constraints.
4744 (machine_ip): When handling case 'i' or 'A', make sure that the
4745 appropriate opcode really exists by looking at the next entry in

4800 * write.c (write_relocs): For relocs that are pc_relative and
4801 pcrel_offset and not partial_inplace, adjust reloc->addend to

4852 OPTIONAL_REGISTER_PREFIX if either is already defined.
4854 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4856 * configure.in: Set bfd_gas for all sparc targets. Added facility
4857 for keeping or rejecting configurations still under development;
4858 default is to assume production environment, and reject configs
4859 still being worked on. Mark Elf configurations (except sparc and
4860 i386) as developmental. Deleted cases matching some generic names
4861 in favor of more specific names. (E.g., when we get Alpha

4879 for functions only used within tc-hppa.c, likewise for structures,
4880 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4881 conditional code in a few small places.
4883 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4884 structures, global variables, forward declarations together.

4886 conditional code -- try to group conditional code together
4887 into a few places. Make all functions and variables which
4888 are only used within tc-hppa.c static. PARAMize all functions.
4889 Add comments to functions. Delete unused functions, variables,
4890 #defines, etc. Delete unused members within structures. Delete
4891 ldil;ble hacks -- it is believed they were installed to work
4892 around old gas bugs. Avoid using mixed case for local
4893 functions, variables, and structures. Fix formatting problems
4894 not found by GNU-indent. Add FIXME notices for things which
4895 should be worked on the near future. Delete lots of old
4896 useless (1.36 PA-SOM) code.

4925 a multiple of the section alignment rather than always a
4928 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4929 bits are zero (eg they specify no relocations), then do not even
4930 bother adding their entries to thesymextn section.

4975 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4977 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4978 ELF, since the ELF object format does not have these type of
4979 relocations. Change the abort into as as_bad and return
4980 BFD_RELOC_NONE to silence compiler warnings.
4981 (md_assemble): Keep track of the instruction size. Allow white
4982 space between the $ and the constant for compatibility with older
4983 gases and other assemblers.

6058 * Extensive changes to permit symbols to contain any expression
6059 type and to delay the computation of the expression until the
6060 value is actually needed. This permits setting symbols to values
6061 calculated based on object code size. Expressions were changed to
6062 no longer be in a section, to stop the overloading of segment and
6063 expression type that previously occurred.

6151 (previous_section, previous_subsection): New vars.
6152 (obj_elf_section): Save current place in case DWARF code wants us
6153 to pop back to it. Handle unquoted section name as well as quoted
6154 section name. Don't crash on invalid strings.
6155 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

6267 sy_resolved and sy_resolving single bit fields.
6268 * symbols.c (symbol_new): Don't initialize sy_forward field.

7416 avoid some redefinition complaints on some systems.

7427 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
7428 (fixup_segment): Add a29k special case; the linker is not prepared
7429 to see a segment offset here.

7434 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
7436 * Makefile.in: add dvi target; as-$(config).texinfo might live in
7437 srcdir, might be in objdir.

7467 dropping a space immediately following an identifier.

7469 lines; I don't think that can be done portably.
7470 * config/tc-mips.c (macro): Use $AT if target register is zero in
7471 load instruction, which it can be for a floating point load.

7964 * obj-vms.c (final_forward_reference): New function, used to help
7965 resolve the data types of as many struct elements as possible
7966 when some part of the struct is not fully defined by the compiler.
7967 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
7969 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7970 as symbols as well in the object file. Look for external functions
7971 that start with "__vt.", and turn them into variables, since the
7972 g++ compiler is incapable of doing this.
7973 * tc-vax.c: Add '1' option for backward compatibility with older GCC
7975 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
7976 * input-scrub.c (as_where): Fix bug where as would crash if we did not

7980 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
7982 * read.c (s_data): Always use "data_section", since it'll map to
7983 SEG_DATA or SEG_E1 if needed.
7984 (s_lcomm): Likewise with bss_section.
7985 (s_fill): Use memset, not bzero.
7987 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

8008 (section_alignment): Declare only if not BFD_ASSEMBLER.
8009 (big_section, reg_section, pass1_section, diff_section,
8010 absent_section, text_section, data_section, bss_section): If
8011 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8012 mapping to segT enum values.
8013 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8014 if these are used or defined, if BFD_ASSEMBLER.
8015 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8016 subseg_new split into two functions.
8017 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8019 * as.h (volatile): Don't define if already defined.
8020 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8022 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8023 declare with format attribute for -Wformat checking.
8025 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8027 * app.c, config/tc-*.c: Don't include read.h, since it is already
8030 * These are based on patches from Minh Tran-le
8031 <mtranle@paris.intellicorp.com>.
8032 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8033 obj_format coffbfd and gas_target i386coff for target.
8034 (i[34]86-*-isc*): New host (uses sysv).
8035 * config/i386aix.mt: Removed (no longer used).
8036 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8038 (LDFLAGS): Added, defined as -shlib.
8039 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8040 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8041 (DOT_LABEL_PREFIX): Define.
8042 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8043 name rather than L0\001.
8044 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8046 * symbols.c, symbols.h (local_bss_counter): Removed.

8055 (size_section): Restored sanity check.
8056 (do_relocs_for): Base section address on s_paddr rather than
8057 computing it. Adjust a29k R_IHIHALF special case to account for
8058 section paddr (used to require paddr to be zero). If there are no
8059 reclos, set s_relptr to 0. Set relocation size in object_headers.
8060 (fill_section): Always set s_vaddr here, removing
8061 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8062 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8063 Set STYP_INFO for .comment.

8067 H_{SET,GET}_* macros.
8068 (do_linenos_for): Set lineno size in object_headers.
8069 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8070 set s_vaddr here. If string_byte_count remains 4, set it back to
8071 0, and only write strings out if there are some. Call
8072 fill_section before do_relocs_for and do_linenos_for.
8073 (obj_coff_section): Handle optional quoted second argument giving
8074 section characteristics.
8075 (obj_coff_bss): Added to handle .bss.
8076 (obj_coff_ident): Added to handle .ident (puts string in .comment

8082 adjustment (already happened only for common symbols, but this is
8084 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

8096 (do_scrub_next_char): For \", return " not '.
8097 (symbol_chars): Now const.
8099 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8100 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8102 * config/obj-coff.h: Don't use #elif.
8104 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8105 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8133 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8134 never set segment address for SEG_E2 (.bss) and don't write out
8135 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8136 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8137 definitions, and don't merge tags with non-tags. Check for .bf
8138 rather than just checking whether the second character is b and
8139 the third character is f.
8140 (obj_coff_val): gcc can generate values which we don't handle
8141 correctly; discard information for now, since it only affects the
8142 debugging information.

8144 (yank_symbols): Don't merge labels.
8145 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8442 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8443 sections starting from zero, rather than making them consecutive.
8444 This makes subsequent reloc calculations easier, esp if the object
8445 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8446 allocate lcomm in .data rather than in .bss. It seems that some
8447 tools can't cope with a non-zero sized bss before linkage.
8449 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8451 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8452 throughout. That enum no longer means what we thought it meant.

8473 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8475 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8476 .word is < -32768 or > 32767. The -J flag causes the error to be
8477 ignored. This is to catch over-sized switches generated by gcc on
8478 systems which don't support the broken .word hack.
8479 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8480 write.c (fixup_segment): check for signed .word overflow if
8481 WARN_SIGNED_OVERFLOW_WORD.

8510 From Steve Chamberlain:
8511 Makefile.in: Handle m68*-*-coff*.
8512 read.c, read.h: add mult argument to s_space
8514 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8515 Motorola and MIT syntax; gas can now assemble either type of
8517 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

8525 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8527 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8530 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8532 * Makefile.in (LIBS): Include opcode library.

8559 * config/tc-m68k.c (init_table): Now const. Always include 68851
8560 data, so that "bc" is available to 68040 cache instructions.
8561 Added "tt0", "tt1", and 68ec030 variants.
8562 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8563 (enum _register): Added TT0, TT1.
8564 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
8565 line number correctly in "internal error" messages. Don't print
8566 architecture-mismatch message for operand errors.
8568 From Colin Smith (colin@wrs.com):
8569 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

8591 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8592 has already been formatted (but may still contain %-characters).
8595 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8597 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8598 written with indirection on the last two operands, which can be
8599 either data or address registers. Added a new operand type 'r'
8600 which accepts either register type. Added '(' to notend stuff in
8601 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8620 their not having symbols associated.
8622 * tc-i960.c (norelax, instrument_branches): Default initializer is
8624 (linkrelax): Delete variable definition.

8937 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8938 copyrights to '92, changed some from Cygnus to FSF.
8940 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8942 * expr.c: If an expression is single comma, then return with
8943 SEG_ABSENT rather than an error - since the sparc front end does
8944 really strange things with things like fbge,a
8946 * as.h: include bfd.h if using many sections
8947 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8948 local labels didn't work.
8949 * listing.c (list_symbol_table): don't core dump when there's no
8951 * write.c, write.h: call fix_new with the right number of args on
8953 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8956 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8958 * app.c: MRI compatibility - allow single quote to start a string.
8959 * as.c: fix typo recently introduced.
8960 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8961 * expr.c: Much rewriting, to accomodate MRI syntax for
8962 expressions. Also easier to read now.
8963 * listing.c: Put back defuns
8964 * read.c: modified to accept MRI syntax, put back listing pseudo
8965 ops so that an assembler built with NO_LISTING ignores list ops
8967 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8968 machine is a SPARC or a 29K.
8969 * config/obj-aout.c: added s_sect pseudo op
8970 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8971 fill in the timestamp.
8972 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8973 anymore, define all the relocs which the tc-<x> bit will use so we
8974 can translate from them to the coff types.
8975 * config/tc-a29k.c: reloc_type isn't ane enum any more
8976 * config/tc-m68k.c: Added NO_RELOC definition.
8978 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8980 * Makefile.in: put header files before C source for TAGS; remove
8981 references to non-existent syscalls.h.
8983 * read.c, write.c subsegs.c: back out the .bss changes.
8985 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8987 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8991 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8993 * symbols.c (local_label_name): symbols now start with ^A.
8995 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8996 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8997 generate these sections. .align: will use NOP_OPCODE or 0
8998 for padding. This is just for being nice to the
9001 * expr.c (operand): changed to generate local label "\001L0"
9002 starting with a ^A so that it is recognized as a local label.
9004 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9006 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9007 i/o opcodes - inb, inw, outb and outw. string manipulation with
9008 att syntax - scmp, slod, smov, ssca, ssto.
9010 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9011 to just after .file .
9013 In obj_crawl_symbol_chain() where it tries to put the external
9014 symbols apart, with the condition:
9015 (!S_IS_DEFINED(symbolP) &&
9016 !S_IS_DEBUG(symbolP) &&
9017 !SF_GET_STATICS(symbolP))
9018 it was moving too many symbols out. So I switch it back to the
9020 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9022 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9023 so that we don't use the F_RELFLG which make the linker complain
9024 that somebody has stripped the relocation info.
9026 Also, the AIX ld program require that the relocation table
9027 is sorted by r_vaddr like the standard ATT assembler does.
9029 [he also changed the sizeof(struct ...)'s into the coff
9030 style FOOSZ macros. I'm not sure this is right, but I can't
9031 remember why. xoxorich.]
9033 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9035 * Makefile.in, configure.in, doc: use the doc. Build it, install
9038 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9040 * read.c: white space and comments only.
9042 * configure.in: use the new atof-ns32.c for ns32k.
9044 * write.c: comment change only.
9046 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9047 aren't yet integrated.
9049 * tc-i860.[hc]: blew off the dust. Something must still be done
9050 about conflicting relocation types.
9052 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9055 * tc-i960.c, tc-sparc.c: white space and comments only.
9057 * tc-a29k.h: delete duplicate macro definition.
9059 * new file atof-ns32k.c copied from hack's last unreleased gas.
9061 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9063 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9066 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9067 ChangeLog's prior to this are sketchy at best. I have logs.
9068 They just aren't ChangeLogs.
9075 version-control: never
