2400 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
2402 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
2403 it's better to use the one in libiberty.
2405 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2407 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
2408 change; it breaks the rs6000 support, and doesn't seem to be
2411 Wed Oct 12 11:56:50 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
2413 * config/tc-i386.h,te-netbsd532.h (TARGET_FORMAT): Changed to

2419 rather than explicitly adding the frag address.
2420 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark
2421 the end of the line numbers; this replaces the zero entry which
2422 used to be added by coff_add_linesym, removed Oct 7.
2423 (coff_adjust_section_syms): Ignore sections with no seginfo.
2425 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2427 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a
2428 "stage" symlink to the appropriate stage* directory, and use it
2429 instead in the -B options.
2430 (comparison): Revert yesterday's change.
2432 Tue Oct 11 16:48:11 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2434 * config/tc-sparc.c (tc_gen_reloc): For non-a.out relocations, if

2437 Tue Oct 11 15:24:00 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
2439 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
2440 for an embedded PIC switch expression, since the definition of
2441 S_IS_LOCAL was changed.
2443 Tue Oct 11 15:05:11 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
2445 * Makefile.in (comparison): When comparing as.new or gasp.new, try
2446 running the binary through sed to avoid differences due to
2447 "stage1" or "stage2" having been written into the binary.
2449 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
2451 ELF symbol size handling, based on code from Eric Youngdale:
2452 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an
2453 expression pointer to the symbol structure, used for `size'
2454 expressions that couldn't be reduced to constants when initially
2456 (elf_frob_symbol): Declare.

2459 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
2461 (obj_elf_size): Deleted unused code. If size is non-reducible
2462 expression, allocate some storage for the sy_obj field and copy
2464 (elf_frob_symbol): New function. Computes sizes, calls
2465 ecoff_frob_symbol if appropriate.
2467 * write.c (fixup_segment): For i386 elf and coff (for now), don't
2468 add in value of symbol from another defined section of the file.
2470 Fri Oct 7 17:54:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

2493 * config/obj-vms.h (S_IS_LOCAL): fix obsolete flagseen[] reference.
2495 Wed Oct 5 11:49:26 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
2497 * config/obj-ecoff.c (obj_pseudo_table): Accept .esize and .etype

2514 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
2516 (diststuff): New target; builds DISTSTUFF.
2517 (realclean): Separate target, depend on clean and distclean, then
2519 * make-gas.com: Deleted.

2522 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
2524 (i386_operand): Don't look up section symbol for
2526 (reloc): Always permit return of 8- and 16-bit relocation types.
2527 Add a space after "pc-relative" in the error message.
2528 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
2529 BFD_RELOC_386_GOTOFF relocs.

2533 (TC_VALIDATE_FIX): New macro -- call it.
2534 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.
2536 * as.h: If __STDC__ is not defined and varargs.h is available, use
2537 it rather than stdarg.h.
2539 * write.h (struct fix): Added new bitfield fx_plt, for fixups
2540 referring to PLT entries.
2541 * write.c (fix_new_internal): Initialize fx_plt to zero.
2542 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
2543 Don't adjust fx_offset by frag address, since S_GET_VALUE now
2544 includes the frag address.
2545 (fixup_segment): Changed local var PCREL to type int, added PLT.
2546 If PC-relative fixup refers to a PLT entry for a symbol in the
2547 current section, don't reduce it.

2553 and after processing.
2554 (print_fixup): Added prototype. Show address on first line. Show
2555 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if

2569 Show fx_r_type and fx_addsy fields.
2571 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2573 * configure.in: Set bfd_gas for all sparc targets in one place,
2574 instead of separately for each. Correctly handle user-supplied
2575 "--enable-bfd-gas" option.
2577 * gdbinit.in: Move "break abort" to end, in case gdb complains.
2579 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
2582 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
2583 processing if add_symbol is undefined or in expr_section.

2585 constant-valued symbol, convert to O_symbol and re-reduce.
2586 (S_GET_VALUE): If symbol needs resolving, resolve it.
2587 (indent_level): No longer static.
2588 (print_symbol_value_1): Don't print frag address if it matches
2589 zero_address_frag. Don't print "resolving" if already resolved.

2592 (print_expr_1): Fix whitespace before printing X_add_number.
2594 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
2595 not symbol_new, for symbols holding expression values.
2596 * expr.h (make_expr_symbol): Move declaration here.
2597 * write.c (fix_new_exp): Handle O_add by creating an
2598 expression-valued symbol, and calling fix_new_exp recursively.
2599 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
2600 undefined symbol and a constant, fold the constant into the fixup,
2601 and refer to the undefined symbol directly. Then process the
2602 fixup again from scratch.
2603 (write_object_file): Before calling adjust_reloc_syms, make a pass
2604 through the symbol list trying to resolve values.
2606 * write.c (print_fixup): New routine, for debugging.
2607 (write_relocs): Call bfd_install_relocation. Deleted various
2608 hacks for working around problems with bfd_perform_relocation.
2610 * Makefile.in (VERSION): Update to 2.4.90.
2612 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2614 * Makefile.in (gasp.o): Depends upon config.h.
2616 * config/tc-mips.c: Include subsegs.h.
2617 (md_apply_fix): If an unconditional b or bal overflows, and we are
2618 not assembling PIC code, replace it with a j or jal.
2620 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
2621 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
2623 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2625 * write.c (write_relocs): Add file name and line number to
2626 as_fatal calls. Handle bfd_reloc_overflow case specifically when
2627 RELOC_EXPANSION_POSSIBLE.
2629 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2631 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
2632 here. Use them for deciding which PRINTF*LIKE macro definitions
2634 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
2635 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
2636 default definitions matching what we were doing before.
2637 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
2638 always use the varargs form if not using stdarg. It's safe to
2639 always use vfprintf, because libiberty will provide it if the
2640 native system doesn't. Also, always make format be const.
2641 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
2643 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

2656 (listing_newline): Check filename as well as line number when
2657 deciding whether to record it.
2658 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
2659 false (if defined) as well as checking for reg_section.
2660 (listing_listing): Iterate fetching lines while line number is too
2661 low, and we haven't run off the end of the input file.
2663 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
2665 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
2667 * ecoff.c (ecoff_generate_asm_lineno): check if
2668 current_stabs_filename is NULL before strcmp.
2669 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
2672 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2674 * config/ho-*.h: Now-unused files deleted.
2676 * symbols.c (copy_symbol_attributes): New function. Copies BFD
2677 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
2678 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
2679 zero. Don't call obj_frob_forward_symbol.
2680 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
2681 X_add_number is zero.
2682 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
2684 * config/tc-i960.c: Lots of whitespace, comment reformatting,
2686 (strchr): Don't declare.
2687 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
2688 md_estimate_size_before_relax, md_ri_to_chars,
2689 md_create_short_jump, md_create_long_jump.
2690 (brtab_emit): Use data_section, not SEG_DATA.
2692 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2694 * config/vms-conf.h: new file, manually derived from conf.in.
2695 * config-gas.com: use it, and eliminate obsolete "host.h".
2697 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2699 * config/tc-ppc.c (ppc_current_block): New static variable.
2700 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
2701 ppc_current_block. Don't move around any stab symbol, just those
2703 (ppc_bs): Set ppc_current_block.
2704 (ppc_es): Clear ppc_current_block.
2705 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
2706 from the csect of the enclosing block.
2708 * config/tc-mips.c (insns_since_cache_access): Remove.
2709 (append_insn): Remove setting of insns_since_cache_access, and
2710 special 4600 handling; it turns out not to be required.
2712 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2714 * config/tc-mips.c (md_shortopts): Remove E.
2715 (md_longopts): Add EB and EL.
2716 (md_parse_option): Handle -EB and -EL as separate options, rather
2717 than as a single -E option with an argument.
2719 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
2721 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
2722 involving global symbols too.
2724 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2726 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
2728 * configure.in: Test for remove, not delete. Fix cross-assembler
2730 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
2733 * read.c (pseudo_set, case O_symbol): If
2734 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
2735 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
2736 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
2738 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
2740 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
2741 many others): new macros; values obtained from "DSTRECRDS.SDL".
2742 * config/obj-vms.h (various): use them.
2743 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
2744 representation (only enum bitfields can avoid being bitstrings).
2745 (bitfield_suffix, setup_basic_type): new routines.
2746 (VMS_typedef_parse): use them. Now recognize bitfields of all
2747 integral types, not just type `int'. Caveat: the representation
2748 used for bitfields still does not work for objects placed in
2749 registers, and gcc's optimizer sometimes puts small structs there.
2751 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2753 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
2754 bit from const_flag.
2755 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
2756 (tc_frob_label): define this to call vms_check_for_special_label,
2757 and declare the latter.
2758 * config/obj-vms.c (vax_g_doubles): declare this file-scope
2760 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
2761 (vms_check_for_special_label): new routine (tc_frob_label).
2762 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
2763 and `gcc2_compiled.' labels; they won't reach here any more.
2764 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
2765 double', use `vax_g_doubles' flag to select type of double.
2766 (VMS_write_object_file) [traceback setup]: don't pass symbols
2767 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
2768 and TBT_Routine_End functions.
2770 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
2772 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
2773 S_GET_VALUE() to avoid many repeated function calls.
2774 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
2775 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
2776 gets requested. [All the HACK_DEC_C_STARTUP code appears to
2777 be obsolete; gcc does it automatically for vms target. It's
2778 also misnamed, because it is for the "VAX C" run-time library,
2779 not the newer "DEC C" one which has much different startup code.]
2780 {various}: use `S_SET_xxx(symbol,new_value)' rather than
2781 `S_GET_xxx(symbol) = new_value'.
2783 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2785 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
2786 not &bfd_abs_section.
2788 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2790 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
2792 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
2794 * expr.c (expr): Don't reduce the difference of two symbols in the
2795 same frag if the symbols are not in normal sections.
2797 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
2798 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
2799 (obj_attach_unwind_info): Do not define. Not needed anymore.
2800 * config/tc-hppa.c: Delete whitespace at EOL.
2801 (struct hppa_fix_struct): Delete fx_unwind field and all references.
2802 (fix_new_hppa): Last arg is now a pointer to an int. Do not
2803 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
2804 fixups, store 32bits of unwind information in the fx_addnumber
2806 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
2807 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
2808 pointer to 32 bits of unwind info.
2809 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
2810 pointer to the dummy symbol; set the addend field to fx_addnumber.
2811 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
2812 rather than &bfd_XXX_section.
2814 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2816 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
2817 value by one; discard adjustments previously being made. From
2820 VMS- and Vax-related changes from Pat Rankin:
2821 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
2822 * vmsconf.sh: no longer have make-gas.com echo text about needing
2823 to modify the gcc-vms driver when intending to use with gcc 1.x.
2824 * as.c (parse_options): suppress 'v' from std_short_options and
2825 eliminate VMS-specific conditional initialization;
2826 [default case]: check for '-v' if md_parse_options doesn't recognize
2828 [default case, #if VMS]: check for filename argument when '-v' seen;
2830 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
2831 for O_big literal operands (double floats and long long ints);
2832 [VMS, md_shortopts]: add second colon after 'v';
2833 (md_parse_options) [VMS, case 'v']: check for argument, so
2834 caller can handle `-v' w/o arg.
2836 Tue Sep 13 16:45:08 1994 Steve Chamberlain (sac@jonny.cygnus.com)

3830 * read.c (emit_expr): Use memset to zero out memory, rather than
3831 going through md_number_to_chars. This permits handling symbolic

3885 (control_regs): New pointer.
3886 (m68k_ip): Use control_regs instead of testing CPU every time.
3887 Use last_movec_reg too. In error messages, handle 68060, and
3888 print 68060 for mfloat, too.

4236 * config/obj-ecoff.c (ecoff_frob_file): Use bfd_ecoff_set_gp_value
4237 and bfd_ecoff_set_regmasks to set the GP value and the register
4238 masks, rather than using the now obsolete fake .reginfo section.
4240 Fri Apr 22 15:17:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4242 * listing.c (list_symbol_table): Don't print register symbols as
4245 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
4246 underscores, since symbol_new will already have done it.
4247 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
4249 * as.c (main): If tc_init_after_args is defined, invoke it after
4250 all arguments have been processed.
4252 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
4253 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
4254 section instead of .text. Call create_target_segments.
4255 * read.c (demand_copy_string): No longer static.
4257 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4259 * config/tc-mips.c (append_insn): Permit branches to be switched
4260 with the preceding instruction even if .set nobopt has been seen.
4261 .set nobopt actually controls whether to bring up an instruction
4262 from the branch target, which gas does not currently support.
4264 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4266 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

4280 multiple of alignment power specified in bfd target vector.
4282 * gasp.c: Include ctype.h.

4293 register mask, skip empty fill frags caused by enabling listing
4296 * config/ho-sysv.h: Include string.h.
4298 * doc/internals.texi: New (well, recently added) file. Just added
4299 info on as_warn and friends.

4303 * config/tc-hppa.c (pa_parse_space_stmt): Use the built-in
4304 defaults for defined, private, and spnum fields for the
4305 $TEXT$ and $PRIVATE$ spaces. Do not clobber spnum. Do
4306 not reset the segment if just updating a space.
4307 (pa_spaces_begin): Set BFD section flags for all built-in
4310 Fri Apr 15 10:51:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

4313 (add_procedure): Set first_proc_ptr if it hasn't been set.
4314 (ecoff_build_lineno): If the first procedure does not start at
4315 address zero, insert a dummy line to compensate.
4317 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
4320 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4322 * expr.c (operand): Try to parse "0f" and "0b" sequences as
4323 floating point and binary numbers respectively; if it doesn't
4324 work, treat them as local labels.
4326 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
4327 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
4329 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
4331 * vmsconf.sh: In generated file, get ".obj" suffix right, build
4332 source files from other directories into objects in the current
4333 directory, and specify PSECT attributes explicitly to linker.
4334 Also added missing label.
4335 * Makefile.in (stamp-mk.com): Reference new variable
4336 VMS_OTHER_OBJS for list of non-local object files, instead of
4338 (VMS_OTHER_OBJS): New variable, added more libiberty files.

4348 * Makefile.in (de-stage1, de-stage2, de-stage3): Use rm -f.
4350 * config/tc-mips.h (DIFF_EXPR_OK): Define.
4351 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
4352 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
4353 argument, the reloc type.
4354 (load_register): Pass reloc type to macro_build for 'u'.
4355 (macro): Likewise. For M_LA_AB permit a difference expression
4356 when generating embedded PIC code between an arbitrary symbol and
4357 a symbol in the .text section.
4358 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
4359 BFD_RELOC_PCREL_LO16 to be emitted.

4363 BFD_RELOC_PCREL_LO16 and BFD_RELOC_PCREL_HI16_S.
4365 Tue Apr 12 18:25:13 1994 Stan Shebs (shebs@andros.cygnus.com)
4367 * subsegs.c (subsegs_begin): Call memset with args in the correct
4369 (subseg_get): Clear newly allocated seginfo, set its pointer slots
4370 to NULL instead of 0.

4374 * config/tc-hppa.c (pa_procend): Handle case where label was
4375 defined after the .proc directive.
4377 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
4378 procend for a procedure without a name.

4392 Thu Apr 7 10:38:18 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4394 * config/tc-hppa.h (elf_tc_symbol): Delete. No longer used.

4399 (hppa_tc_symbol): Likewise.
4401 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
4402 elf_tc_make_sections stuff. It was there to support PA braindamage
4403 which has been fixed, and in the case of elf_tc_make_sections is
4404 redundant with elf_tc_final_processing.
4406 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4408 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the
4411 Tue Apr 5 15:48:03 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4413 * config/tc-mips.c (mips_ip): For case 'o', when generating
4414 embedded PIC code, accept the difference between two local symbols
4416 (mips_force_relocation): Only force a reloc to be generated for a
4418 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
4419 value into the file if the fixup will not generate a reloc.
4421 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
4423 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
4424 don't spew remainder of input file in error message.
4425 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
4426 message with reloc type and try to process remainder of file.
4428 * doc/Makefile.in (install-info-as, install-info-gasp): New
4429 targets, now explicitly checking $(srcdir) for info files.
4430 (install-info): Depend on both of them; do nothing more.
4432 Mon Apr 4 17:06:04 1994 Jeffrey A. Law (law@cygnus.com)
4434 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
4436 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4438 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
4439 flag rather than signedp field. Only permit extended range if
4440 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
4441 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
4443 * config/tc-ppc.c (ppc_size): New static variable.
4444 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
4445 (md_begin): If an instruction has a size specific flag set, only
4446 add it if we are assembling that size.
4448 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4450 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
4451 cross section PC relative relocs right for COFF and ELF.
4453 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4455 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
4456 (OBJ_PROCESS_STAB): Don't define.
4458 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4460 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
4461 the type of symbol set symbols which happen to be in the absolute
4462 or undefined section.
4464 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
4466 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
4467 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
4468 and -many (all architectures).
4470 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4472 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
4473 involving a function symbol which is not a plabel to zero.
4474 (md_apply_fix): Never pass a function symbol to field_adjust.
4476 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4478 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
4479 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
4481 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
4482 branch with an instruction that uses $at, in case the branch is
4484 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
4485 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
4486 to make it pcrel_offset.
4487 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
4488 reloc->address; another gruesome hack to get gas reloc handling to
4491 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4493 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
4496 (emit_insn): New function.
4497 (md_assemble): Call it.
4498 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
4500 (lituse_pending): New variable. Set by anything that generates a
4501 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
4502 tested by code that might want to emit a LITUSE reloc.
4503 (emit_unaligned_io): New function. Currently calls md_assemble,
4504 but it should eventually be converted to generate the insn itself
4505 and call emit_insn directly.
4506 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
4507 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
4508 emit_bis_r): Likewise.
4509 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
4510 (alpha_ip, label get_macro): Don't emit the final instruction if
4512 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
4513 unaligned memory access macros.
4514 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
4515 the value can't be resolved.
4517 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4519 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
4520 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
4521 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
4523 (mips_force_relocation): New function.
4524 (md_apply_fix): Set fixP->fx_done appropriately.
4525 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

4533 * config/tc-mips.c (enum mips_pic_level): New enum.
4534 (mips_pic): Change from int to enum mips_pic_level. Change all
4535 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
4536 (load_address): Handle EMBEDDED_PIC.
4537 (macro): Handle EMBEDDED_PIC in all PIC cases.
4538 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
4539 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
4540 -non_shared to use NO_PIC (this is how the Irix 5 assembler
4541 works). Do not permit -G with SVR4_PIC.
4542 (s_abicalls): Warn if -G was used, and force -G 0.
4543 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
4544 anything but a.out, not just for ELF. For ECOFF, don't generate a
4545 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
4547 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
4549 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4551 * config/tc-hppa.c (create_new_space): Use ints, not chars as
4552 parameters to avoid losing when compiling with HP CC.
4553 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
4555 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4557 * Makefile.in (config-stamp): If `defs' is defined, emit a
4558 preprocessor directive to create a macro named by this value into
4559 config.new; don't explicitly go for BFD_ASSEMBLER.
4560 * configure.in: Define `defs', not `BFDDEF'. Set it to
4561 MANY_SEGMENTS for any obj-coffbfd target.
4562 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
4563 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
4565 (LOCAL_LOADLIBES): Deleted.
4566 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
4567 * config/m88kcoff.mt (TDEFINES): Ditto.
4568 * config/ebmon29k.mt: Deleted.
4569 * config/h8300hds.mt: Deleted.
4570 * config/ic960coff.mt: Deleted.
4571 * config/sparc.mt: Deleted.
4572 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
4573 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
4574 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
4575 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

4593 bfd_set_symtab is called.
4594 (dump_section_relocs): Note whether a symbol is a section symbol
4596 (adjust_reloc_syms): For now, always supply an absolute symbol for
4597 fixups without symbols but not yet `done'. Use section_symbol to
4598 get the symbol, instead of going directly for abs_symbol.
4599 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
4600 reloc is not a section symbol and is not in the symbol table.
4601 (set_symtab): New function, broken out from write_object_file.
4602 Counts symbol table instead of relying on an earlier count.
4603 (write_object_file): Call set_symtab, but do it after potentially
4604 invoking the *_frob_file macros. Don't bother counting symbols.
4605 Call symbol_remove, instead of expanding it in place. Moved the
4606 conditionalized `object_file_size' declaration down to
4607 conditionalized block where it's used. When using the absolute
4608 symbol for a fixup without a symbol, set sy_used_in_reloc.
4609 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
4610 the correct symbol for the absolute section.
4612 * subsegs.c (section_symbol): Use symbol_new instead of
4613 symbol_make, since we may want it to go into the symbol table.
4614 Make the new symbol have internal linkage. If
4615 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
4616 symbol with the newly created GAS symbol.
4617 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
4618 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
4620 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
4622 * config/tc-sparc.c: Include subsegs.h.
4623 (in_signed_range): New function.
4625 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
4626 (sparc_ip, label "immediate"): Reject constants for pcrel
4627 instructions only if the relocation type indicates a "call"
4628 instruction and the offset is within range of a "jmpl %g0". If
4629 it's not in range, use the absolute section symbol plus an offset.
4630 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
4632 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
4634 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
4637 * configure.in: Eliminated all targets using obj-coff but not
4638 defining BFD_ASSEMBLER; I think all such targets that are
4639 supported will be matched by real CPU-OS combinations earlier in
4641 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
4642 some comments about the dpx2 configuration, but left it disabled,
4643 since it couldn't be reached before.
4644 (target a29k-amd-ebmonold): Deleted.
4646 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4653 * config/tc-mips.c (mips_ip): Only accept overly large values for
4654 the 'j' operand if there are no further alternatives for this
4657 * config/obj-coffbfd.c (adjust_stab_section): Initialize
4658 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
4659 is not SEG_UNKNOWN rather than checking whether it is >= 0.
4661 * config/tc-mips.c (mips_align): Take new argument, label, and use
4662 it instead of global insn_label.
4663 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
4664 call to mips_emit_delay and pass it to mips_align.
4666 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4668 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
4670 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
4671 argument to a .callinfo directive. Don't loop forever on errors.
4673 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
4674 use pre-defined registers as arguments.
4676 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

6459 of interest to the linker. ENTRY/EXIT relocations for SOM are
6460 an example of marker relocations.
6461 * write.c (write_relocs): Instead of assuming size of a relocation
6462 is 4 bytes, pick up the size from relocation itself.

6490 BFD_RELOC_MIPS_GPREL. Added new case a.
6491 (set_at, load_register, macro): Changed calls to macro_build to
6492 pass new argument for i, j and o cases.
6493 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
6494 special handling when generating SVR4 PIC code.

6828 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
6830 * configure.in: Set bfd_gas for all sparc targets. Added facility
6831 for keeping or rejecting configurations still under development;
6832 default is to assume production environment, and reject configs
6833 still being worked on. Mark Elf configurations (except sparc and
6834 i386) as developmental. Deleted cases matching some generic names
6835 in favor of more specific names. (E.g., when we get Alpha

6852 through inclusion of tc-hppa.h. Delete all forward declarations
6853 for functions only used within tc-hppa.c, likewise for structures,
6854 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
6855 conditional code in a few small places.
6857 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
6858 structures, global variables, forward declarations together.

6861 into a few places. Make all functions and variables which
6862 are only used within tc-hppa.c static. PARAMize all functions.
6863 Add comments to functions. Delete unused functions, variables,
6864 #defines, etc. Delete unused members within structures. Delete
6865 ldil;ble hacks -- it is believed they were installed to work
6866 around old gas bugs. Avoid using mixed case for local
6867 functions, variables, and structures. Fix formatting problems
6868 not found by GNU-indent. Add FIXME notices for things which
6869 should be worked on the near future. Delete lots of old
6870 useless (1.36 PA-SOM) code.

6949 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
6951 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
6952 ELF, since the ELF object format does not have these type of
6953 relocations. Change the abort into as as_bad and return
6954 BFD_RELOC_NONE to silence compiler warnings.
6955 (md_assemble): Keep track of the instruction size. Allow white
6956 space between the $ and the constant for compatibility with older
6957 gases and other assemblers.

7921 w/ ANSI, and which weren't needed anyway
7923 Wed Jul 28 16:34:55 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
7925 * config/obj-elf.h (obj_frob_symbol): Renamed from tc_frob_symbol,

7967 are also magic, and have special default flag settings.
7968 (obj_elf_frob_symbol): Since the return value from this function

8032 * Extensive changes to permit symbols to contain any expression
8033 type and to delay the computation of the expression until the
8034 value is actually needed. This permits setting symbols to values
8035 calculated based on object code size. Expressions were changed to
8036 no longer be in a section, to stop the overloading of segment and
8037 expression type that previously occurred.
8039 * as.c (big_section, pass1_section, diff_section, absent_section):
8041 (expr_section): Added (used for dummy symbols which hold

8125 (previous_section, previous_subsection): New vars.
8126 (obj_elf_section): Save current place in case DWARF code wants us
8127 to pop back to it. Handle unquoted section name as well as quoted
8128 section name. Don't crash on invalid strings.
8129 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

8241 sy_resolved and sy_resolving single bit fields.
8242 * symbols.c (symbol_new): Don't initialize sy_forward field.

9336 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
9337 the bottom (make expands variables in dependencies when the
9338 dependencies are read, not when they are used).
9340 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
9341 a29k .bss section; the mondfe program doesn't like it.

9362 source directory, if that's not the current directory.
9364 * configure.in (per-host): Accept MIPS host with BSD version

9390 avoid some redefinition complaints on some systems.
9391 (const, volatile): Don't need these conditionally defined if we
9392 use CONST and VOLATILE from ansidecl.h.
9393 (seg_name): Use CONST, not const.
9395 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
9397 * config/tc-mips.c: Reindented to GNU standards.
9399 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
9401 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

9408 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
9410 * Makefile.in: add dvi target; as-$(config).texinfo might live in

9441 dropping a space immediately following an identifier.
9442 * expr.c, write.c: Rewrote assert expressions to not use multiple
9443 lines; I don't think that can be done portably.
9444 * config/tc-mips.c (macro): Use $AT if target register is zero in
9445 load instruction, which it can be for a floating point load.
9447 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

9458 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
9459 z8k-opc.h, not z8k.h.
9461 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
9464 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9466 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
9468 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
9470 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

9519 prototypes for all static functions. Moved existing minimal
9520 debugging format support info #ifndef OBJ_ECOFF blocks.

9569 * make-gas.com: Find obstack.obj if it's not in the current
9571 * read.c (s_ignore): Don't declare is_end_of_line. It's
9572 redundant, and triggers a VMS gcc compiler bug.
9574 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
9575 current segment as an argument. (Ignored in all cases but VMS.)
9576 All callers and definitions changed.

9600 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
9603 * configure.in: mips-bsd configuration was missing format spec.
9606 * Makefile.in (Makefile): Depends on configure.in.
9608 * config/tc-mips.c (append_insn): Don't check for alignment of
9609 frag in memory; alignment of instructions in section is a separate

9629 * config/tc-sparc.c (s_xword): Now call big_cons, so large
9630 constants are accepted, but symbolic values are not. GCC will not
9631 generate the latter currently.
9633 * frags.c (frag_init): New function.
9634 (zero_address_frag, bss_address_frag): Now initialized at run
9636 * as.c (main): Call frag_init.

9714 * read.c: Don't include ctype.h.
9715 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
9716 for now; should be machine-dependent.
9718 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
9719 targets, forcing BFD use.

9888 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
9889 latter, instead of selecting with preprocessor conditionals.
9891 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9893 * configure.in: recognise all sparclite variants
9895 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
9897 * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --

9903 * expr.c (operand): If character other than comma or newline is a
9904 logical end-of-line character, use the newline case.
9905 From Eric Youngdale:
9906 (operand): Set X_add_number field for floating-point numbers.
9907 (operand): Treat zero byte as end-of-operand.
9909 * configure.in (per-target): Look for with_bfd_assembler option.
9910 For now, only accept "no", until the merge is done.
9912 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
9913 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
9914 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
9915 * read.c: Finish conversion to S_* macros in the VMS only
9916 parts of the program. Add "const" modifier to hex_value.
9917 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
9919 * expr.c: Add "const" modifier to hex_value.
9920 * symbols.c: Finish conversion to S_* macros in the VMS only
9921 parts of the program. Add "const" modifier to
9922 md_[long,short]_jump_size. Remove declaration of const_flag
9923 (which will be declared in obj-vms.h).
9924 * write.c: Add "const" modifier to md_[long,short]_jump_size.
9925 Fix arguments to VMS_write_object_file.
9926 * config-gas.com: New file. Script for VMS systems to set up the
9927 configuration to build gas for VMS, and create config.status.
9928 * make-gas.com: Redone to work with new scheme.
9929 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
9931 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
9932 will swap bytes if needed on a big endian system. Use throughout
9934 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
9935 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
9936 types of malformed stabs. Change parsing algorithm so that we are
9937 more certain of having all of the information that we need on hand.
9938 * obj-vms.c (final_forward_reference): New function, used to help
9939 resolve the data types of as many struct elements as possible
9940 when some part of the struct is not fully defined by the compiler.
9941 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
9943 * obj-vms.c (VMS_write_object_file): Define all vtable psects
9944 as symbols as well in the object file. Look for external functions
9945 that start with "__vt.", and turn them into variables, since the
9946 g++ compiler is incapable of doing this.
9947 * tc-vax.c: Add '1' option for backward compatibility with older GCC
9949 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
9950 * input-scrub.c (as_where): Fix bug where as would crash if we did not
9951 have the name of the source file yet.
9952 * config/ho-vms.h: define HO_VMS, not HO_VAX.
9954 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
9956 * read.c (s_data): Always use "data_section", since it'll map to
9957 SEG_DATA or SEG_E1 if needed.
9958 (s_lcomm): Likewise with bss_section.
9959 (s_fill): Use memset, not bzero.
9961 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

9980 otherwise, use seg_name array.
9981 (seg_name): Declare only if not BFD_ASSEMBLER.
9982 (section_alignment): Declare only if not BFD_ASSEMBLER.
9983 (big_section, reg_section, pass1_section, diff_section,
9984 absent_section, text_section, data_section, bss_section): If
9985 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
9986 mapping to segT enum values.
9987 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
9988 if these are used or defined, if BFD_ASSEMBLER.
9989 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
9990 subseg_new split into two functions.
9991 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
9993 * as.h (volatile): Don't define if already defined.
9994 (had_errors, had_warnings): Provide prototypes for ANSI C even if
9996 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
9997 declare with format attribute for -Wformat checking.
9999 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
10001 * app.c, config/tc-*.c: Don't include read.h, since it is already
10004 * These are based on patches from Minh Tran-le
10005 <mtranle@paris.intellicorp.com>.
10006 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
10007 obj_format coffbfd and gas_target i386coff for target.
10008 (i[34]86-*-isc*): New host (uses sysv).
10009 * config/i386aix.mt: Removed (no longer used).
10010 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
10011 (MINUS_G): Removed.
10012 (LDFLAGS): Added, defined as -shlib.
10013 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
10014 * config/te-sco386.h (LOCAL_LABEL): Don't define.
10015 (DOT_LABEL_PREFIX): Define.
10016 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
10017 name rather than L0\001.
10018 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
10020 * symbols.c, symbols.h (local_bss_counter): Removed.
10021 * write.c (write_object_file): bss no longer uses
10022 local_bss_counter. Pass correct data and bss size to
10023 VMS_write_object_file.

10029 (size_section): Restored sanity check.
10030 (do_relocs_for): Base section address on s_paddr rather than
10031 computing it. Adjust a29k R_IHIHALF special case to account for
10032 section paddr (used to require paddr to be zero). If there are no
10033 reclos, set s_relptr to 0. Set relocation size in object_headers.
10034 (fill_section): Always set s_vaddr here, removing
10035 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
10036 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
10037 Set STYP_INFO for .comment.
10038 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
10039 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

10041 H_{SET,GET}_* macros.
10042 (do_linenos_for): Set lineno size in object_headers.
10043 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
10044 set s_vaddr here. If string_byte_count remains 4, set it back to
10045 0, and only write strings out if there are some. Call
10046 fill_section before do_relocs_for and do_linenos_for.
10047 (obj_coff_section): Handle optional quoted second argument giving
10048 section characteristics.
10049 (obj_coff_bss): Added to handle .bss.
10050 (obj_coff_ident): Added to handle .ident (puts string in .comment

10070 (do_scrub_next_char): For \", return " not '.
10071 (symbol_chars): Now const.
10073 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
10074 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
10076 * config/obj-coff.h: Don't use #elif.
10078 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
10079 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
10081 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
10083 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

10105 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
10106 using ZERO_BASED_SEGMENTS.
10107 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
10108 never set segment address for SEG_E2 (.bss) and don't write out
10109 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
10110 (obj_coff_endef): Don't merge labels or symbols awaiting forward
10111 definitions, and don't merge tags with non-tags. Check for .bf
10112 rather than just checking whether the second character is b and
10113 the third character is f.
10114 (obj_coff_val): gcc can generate values which we don't handle
10115 correctly; discard information for now, since it only affects the
10116 debugging information.
10117 (tag_find_or_name): Don't insert tags in the symbol table.
10118 (yank_symbols): Don't merge labels.
10119 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

10273 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
10275 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
10277 * subsegs.h: add extern to segment_info declaration.
10279 * read.h: added extern declarations for comment_chars,
10280 line_comment_chars, and line_separator_chars.
10281 read.c, app.c: removed definitions of comment_chars,
10282 line_comment_chars, and line_separator_chars.
10284 * tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
10285 still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
10287 (insert_reg): put REGISTER_PREFIX before register names before
10288 putting them in the symbol table.
10289 * tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not
10292 * obj-coffbfd.c (fill_section): set STYP_NOLOAD bit for .bss
10295 * atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
10296 comment_chars, line_comment_chars and line_seperator_chars
10297 consistently const, and always initialized them. Included read.h.
10299 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
10301 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
10302 constant will not fit in an immediate field.
10303 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
10305 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
10307 * obj-coff.c (callj_table): Delete global variable.
10308 (obj_emit_relocations): Define it locally here, and only if
10309 TC_I960 is defined.
10311 * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.
10312 (m68k_ip): Don't warn about bignum used as float bit-pattern.
10314 * obj-coff.c: Replaced ANSI and non-ANSI function declarations
10315 with a single set using PARAMS macro.
10317 * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length
10320 * tc-i960.c: Missed a couple of 0->NO_RELOC conversions.
10322 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
10323 so widening works consistently.
10325 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
10327 * version.c: Put conditional "const" before version_string, not
10328 before dummy function for VMS. Now version 1.91.03.
10330 * app.c (do_scrub_next_char): Need double-\ before `000' to show
10331 printed rep of null character.
10333 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
10335 * obj-coffbfd.c (write_object_file): check return value of
10336 bfd_close_all_done.
10338 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
10340 * Support for i386-sysv.
10341 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
10342 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
10343 be used to set them all to zero as was done before.
10344 (fill_section): segment addresses now set in write_object_file.
10345 (fill_section): Don't set STYP_NOLOAD for .bss section.
10346 (fixup_segment): 386 uses strange common symbol format.
10347 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
10348 compatibility with SVR3.2 linker.
10349 * configure.in: i386-sysv and i386-sco use coffbfd.
10351 * app.c (do_scrub_next_char): discard whitespace after a label.
10353 Sat Oct 10 12:33:45 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

10360 fix i960+non-bfd coff bit rot.
10361 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
10362 support for C source listings. (obj_coff_endef): look in the right
10363 part of the symbol for the symbol name
10365 * tc-m68k.c (get_num): make it work for all segments, not just the

10370 * configure.in: recognize i386-*-bsd emulation.
10372 Thu Oct 1 23:05:12 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
10374 * configure.in: use the cpu-vendor-os triple for host and target
10376 Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com)

10381 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
10383 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
10384 #elif, since it is not supported by old compilers.
10385 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
10386 couple of expressions in tc-m68k.c.
10388 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10390 * read.c (cons): If NO_RELOC is defined, use it.
10392 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
10394 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
10396 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
10397 local labels to start with a .) and set REGISTER_PREFIX to %.
10398 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
10400 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
10402 * messages.c: Comment changes.
10404 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
10406 * as.h: Test if __STDC__ is defined only, don't test its value.
10407 * messages.c: If __STDC__ is not defined, define NO_STDARG.
10409 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
10411 * listing.c (debugging_pseudo): Add stabs and stabn as things to
10414 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
10416 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
10417 sections starting from zero, rather than making them consecutive.
10418 This makes subsequent reloc calculations easier, esp if the object
10419 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
10420 allocate lcomm in .data rather than in .bss. It seems that some
10421 tools can't cope with a non-zero sized bss before linkage.
10423 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10425 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10426 throughout. That enum no longer means what we thought it meant.
10428 * tc-m68k.c (md_assemble, md_parse_option): Handle new
10429 "-mno-688[58]1" options.
10431 * tc-m68k.c: Added CPU32 support.
10433 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10435 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
10437 Tue Sep 15 17:25:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
10439 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
10440 Change LIBDEPS dependence to LIBS.
10442 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
10444 * Makefile.in (install): if $(tooldir) exists, install as in
10447 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10449 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10450 .word is < -32768 or > 32767. The -J flag causes the error to be
10451 ignored. This is to catch over-sized switches generated by gcc on
10452 systems which don't support the broken .word hack.
10453 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10454 write.c (fixup_segment): check for signed .word overflow if
10455 WARN_SIGNED_OVERFLOW_WORD.
10457 * write.c (fixup_segment): fixed missing parens in expression
10458 checking for byte or word overflow.
10460 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
10461 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
10462 WARN_SIGNED_OVERFLOW_WORD.
10464 * obj-coffbfd.c (fixup_segment): fixed missing parens in
10465 expression checking for byte or word overflow.
10467 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10469 Support for i386 coff
10470 * obj-coffbfd.h : added stuff
10471 * tc-i386.c (tc_coff_fix2rtype): new function
10472 * tc-i386.h : new coff defines
10474 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
10476 * input-scrub.c (input_scrub_push): call input_file_begin, not
10478 messages.c (as_perror): print ": " between the passed in error and
10479 the strerror, like perror does.
10481 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
10483 * Makefile.in: use gas_target instead of modifying target_cpu.
10484 From Steve Chamberlain:
10485 Makefile.in: Handle m68*-*-coff*.

10488 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
10489 Motorola and MIT syntax; gas can now assemble either type of
10491 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
10492 From Steve Chamberlain:
10493 m68kcoff.mt: for m68k COFF.
10494 obj-coffbfd.c: (fixup_mdeps) added
10495 (size_section) removed bad sanity check
10496 (fill_section) added rs_machine_dependent case
10497 (write_object_file) call fixup_mdeps
10498 (fixup_segment) set fx_subsy to 0.
10499 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
10501 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
10504 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10506 * Makefile.in (LIBS): Include opcode library.

10527 * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
10528 tc-i960.c (md_ri_to_chars): Always output bout object file in
10529 little endian byte order (used to use endianness of host).
10531 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10533 * config/tc-m68k.c (init_table): Now const. Always include 68851
10534 data, so that "bc" is available to 68040 cache instructions.
10535 Added "tt0", "tt1", and 68ec030 variants.
10536 (md_assemble): Complain if 68000 (only) and 68881 are specified.
10537 (enum _register): Added TT0, TT1.
10538 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
10539 line number correctly in "internal error" messages. Don't print
10540 architecture-mismatch message for operand errors.
10542 From Colin Smith (colin@wrs.com):
10543 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
10544 than install_operand.

10553 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
10555 * Makefile.in: defined TARGET_CPU for C code so that it can choose
10556 one element of a family.
10558 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
10560 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
10561 so that we can assemble hand-written libgcc code.
10563 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10565 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
10566 has already been formatted (but may still contain %-characters).
10567 (as_bad): Likewise.
10569 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
10571 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
10572 written with indirection on the last two operands, which can be
10573 either data or address registers. Added a new operand type 'r'
10574 which accepts either register type. Added '(' to notend stuff in
10575 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
10577 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
10579 * as.h (enum _relax_state): Start off at one, not zero, to better
10580 catch uninitialized-variable errors.
10581 (linkrelax): Declare new variable.
10583 * messages.c (warning_count, error_count): Default initializer is
10586 * write.c: Merged some declarations, using PARMS macro.

10588 data_last_frag): No longer static.
10589 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
10590 defined, call it. Change segments before calling fixup_segment.
10591 (relax_align): If linkrelax, provide extra padding.
10593 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
10594 their not having symbols associated.
10596 * tc-i960.c (norelax, instrument_branches): Default initializer is
10598 (linkrelax): Delete variable definition.

10619 Mon Aug 17 15:09:56 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10621 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
10622 being used with args swapped, causing occasional lossage when
10623 refilling buffers after an include file.
10625 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
10627 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
10628 version. Discard bogus DONTDEF version.
10629 (as_warn, as_bad, as_fatal): Likewise.
10631 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
10633 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
10634 selected architecture, print a message saying so and listing what
10635 processors support it, rather than saying "operands mismatch".
10637 Thu Aug 13 13:53:19 1992 Ken Raeburn (raeburn@cygnus.com)
10639 * as.h [BROKEN_ASSERT]: If defined, turn off all assertion checks.

10651 * tc-m68k.c: ".align N" means align to N-byte boundary *only*
10652 if TN_SUN3; otherwise align to 2**N-byte bounary.
10654 Thu Aug 6 12:10:39 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10656 * read.c (s_fill): make the .fill size clamped error a warn and
10657 fix bug where 0's were always placed.
10659 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
10660 two bytes of any constant with 0xff:
10662 Wed Aug 5 12:02:40 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10664 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
10665 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.
10667 Wed Aug 5 01:54:34 1992 John Gilmore (gnu at cygnus.com)
10669 * tc-m68k.c (try_index): Error if index scaling specified and
10670 assembling for an older CPU than a 68020.
10672 Sat Aug 1 19:10:13 1992 Ken Raeburn (raeburn@cygnus.com)
10674 * config/tc-sparc.c (tc_aout_fix_to_chars): If pc-relative, take
10675 fx_offset into account.

10679 * configure.in (mips host): Accept "ultrix" with version number.
10681 * expr.c (floating_constant): Separate "=-" to avoid confusing
10682 ancient or broken compilers.
10684 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
10685 processor/opcode mismatch, so reword the error message.
10686 (md_assemble): If no CPU has been set (even if FPU/PMMU
10687 characteristics have been), default to 68020. Don't need extra
10688 quotes around error string.
10690 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
10692 * read.c (potable): Revert sac's incorrect change made Jul 13.
10693 Align really is supposed to be ptwo not nbytes.
10695 Mon Jul 20 02:51:59 1992 D. V. Henkel-Wallace (gumby@cygnus.com)
10697 * Makefile.in: _Do_ include libiberty. (from sef)
10699 Fri Jul 17 15:15:28 1992 Ken Raeburn (raeburn@cygnus.com)
10701 * expr.c (integer_constant): Handle "0f" and "0b" label references

10750 pcrel data stuff. (md_estimate_size_before_relax): when relaxing a
10751 68010 bxx into a bra+6 jmpxx, put the bytes of the jmp opcode into
10752 the right place. (s_bss): Don't put .bss stuff into SEG_DATA, put

10777 * configure.in: recognize m680x0 as having sun3 emulation mode for
10778 vxworks environment.
10780 Sun May 31 05:33:00 1992 david d `zoo' zuhn (zoo@cygnus.com)

10804 * tc-a29k.c (parse_operand): allow expressions to be in any section.
10806 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
10808 * as.c, write.c: use -K rather than -k for the broken word warning
10811 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
10813 * Makefile.in: do not print recursion lines.
10815 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)

10824 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
10826 * Makefile.in (install): Install into $(tooldir)/bin, since that's
10827 where gcc looks for it.
10829 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
10831 * Makefile.in: Changed some lines to be less confusing for some

10863 * configure.in: vxworks68 gets te-sun3.h.
10865 * expr.c: remove limitation that local_labels_dollar or
10866 local_labels_fb must be < 10.
10868 * symbols.c: remove local_labels_dollar, replace with a function
10869 interface for a sparse array. All users adjusted.
10871 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
10873 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

10897 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
10899 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
10901 * expr.c (operand): if can't work out what sort of operand it is,
10902 then look through FLT_CHARS for a hint.
10904 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
10906 * Makefile.in, configure.in: removed traces of namesubdir,
10907 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10908 copyrights to '92, changed some from Cygnus to FSF.
10910 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
10911 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10912 copyrights to '92, changed some from Cygnus to FSF.
10914 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10916 * expr.c: If an expression is single comma, then return with
10917 SEG_ABSENT rather than an error - since the sparc front end does
10918 really strange things with things like fbge,a
10920 * as.h: include bfd.h if using many sections
10921 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
10922 local labels didn't work.
10923 * listing.c (list_symbol_table): don't core dump when there's no
10925 * write.c, write.h: call fix_new with the right number of args on
10927 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
10930 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10932 * app.c: MRI compatibility - allow single quote to start a string.
10933 * as.c: fix typo recently introduced.
10934 * as.h : Don't include aout/reloc.h - it's not right for COFF!
10935 * expr.c: Much rewriting, to accomodate MRI syntax for
10936 expressions. Also easier to read now.
10937 * listing.c: Put back defuns
10938 * read.c: modified to accept MRI syntax, put back listing pseudo
10939 ops so that an assembler built with NO_LISTING ignores list ops
10941 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
10942 machine is a SPARC or a 29K.
10943 * config/obj-aout.c: added s_sect pseudo op
10944 * config/obj-coffbfd.c: lints, set the filehdr flags right and
10945 fill in the timestamp.
10946 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
10947 anymore, define all the relocs which the tc-<x> bit will use so we
10948 can translate from them to the coff types.
10949 * config/tc-a29k.c: reloc_type isn't ane enum any more
10950 * config/tc-m68k.c: Added NO_RELOC definition.
10952 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10954 * Makefile.in: put header files before C source for TAGS; remove
10955 references to non-existent syscalls.h.
10957 * read.c, write.c subsegs.c: back out the .bss changes.
10959 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
10961 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
10963 * a.out.h: removed.
10965 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
10967 * symbols.c (local_label_name): symbols now start with ^A.
10969 * read.c, subsegs.c, write.c obj-coff.c: added handling of
10970 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
10971 generate these sections. .align: will use NOP_OPCODE or 0
10972 for padding. This is just for being nice to the
10975 * expr.c (operand): changed to generate local label "\001L0"
10976 starting with a ^A so that it is recognized as a local label.
10978 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
10980 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
10981 i/o opcodes - inb, inw, outb and outw. string manipulation with
10982 att syntax - scmp, slod, smov, ssca, ssto.
10984 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
10985 to just after .file .
10987 In obj_crawl_symbol_chain() where it tries to put the external
10988 symbols apart, with the condition:
10989 (!S_IS_DEFINED(symbolP) &&
10990 !S_IS_DEBUG(symbolP) &&
10991 !SF_GET_STATICS(symbolP))
10992 it was moving too many symbols out. So I switch it back to the
10994 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
10996 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
10997 so that we don't use the F_RELFLG which make the linker complain
10998 that somebody has stripped the relocation info.
11000 Also, the AIX ld program require that the relocation table
11001 is sorted by r_vaddr like the standard ATT assembler does.
11003 [he also changed the sizeof(struct ...)'s into the coff
11004 style FOOSZ macros. I'm not sure this is right, but I can't
11005 remember why. xoxorich.]
11007 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
11009 * Makefile.in, configure.in, doc: use the doc. Build it, install
11012 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
11014 * read.c: white space and comments only.
11016 * configure.in: use the new atof-ns32.c for ns32k.
11018 * write.c: comment change only.
11020 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
11021 aren't yet integrated.
11023 * tc-i860.[hc]: blew off the dust. Something must still be done
11024 about conflicting relocation types.
11026 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
11029 * tc-i960.c, tc-sparc.c: white space and comments only.
11031 * tc-a29k.h: delete duplicate macro definition.
11033 * new file atof-ns32k.c copied from hack's last unreleased gas.
11035 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
11037 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
11040 * nearly everything. flush ChangeLog, package as gas-1.92.1.
11041 ChangeLog's prior to this are sketchy at best. I have logs.
11042 They just aren't ChangeLogs.
