2393 "stage1" or "stage2" having been written into the binary.
2395 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
2397 ELF symbol size handling, based on code from Eric Youngdale:
2398 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an
2399 expression pointer to the symbol structure, used for `size'
2400 expressions that couldn't be reduced to constants when initially
2402 (elf_frob_symbol): Declare.
2403 (obj_frob_symbol): Call elf_frob_symbol always, rather than

2405 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
2407 (obj_elf_size): Deleted unused code. If size is non-reducible
2408 expression, allocate some storage for the sy_obj field and copy
2410 (elf_frob_symbol): New function. Computes sizes, calls
2411 ecoff_frob_symbol if appropriate.
2413 * write.c (fixup_segment): For i386 elf and coff (for now), don't
2414 add in value of symbol from another defined section of the file.

2462 (diststuff): New target; builds DISTSTUFF.
2463 (realclean): Separate target, depend on clean and distclean, then
2465 * make-gas.com: Deleted.

2473 Add a space after "pc-relative" in the error message.
2474 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
2475 BFD_RELOC_386_GOTOFF relocs.

2479 (TC_VALIDATE_FIX): New macro -- call it.
2480 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.

2485 * write.h (struct fix): Added new bitfield fx_plt, for fixups
2486 referring to PLT entries.
2487 * write.c (fix_new_internal): Initialize fx_plt to zero.
2488 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
2489 Don't adjust fx_offset by frag address, since S_GET_VALUE now
2490 includes the frag address.
2491 (fixup_segment): Changed local var PCREL to type int, added PLT.
2492 If PC-relative fixup refers to a PLT entry for a symbol in the
2493 current section, don't reduce it.

2515 Show fx_r_type and fx_addsy fields.
2517 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2519 * configure.in: Set bfd_gas for all sparc targets in one place,
2520 instead of separately for each. Correctly handle user-supplied
2521 "--enable-bfd-gas" option.
2523 * gdbinit.in: Move "break abort" to end, in case gdb complains.
2525 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
2528 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
2529 processing if add_symbol is undefined or in expr_section.

2533 (indent_level): No longer static.
2534 (print_symbol_value_1): Don't print frag address if it matches

2538 (print_expr_1): Fix whitespace before printing X_add_number.
2540 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
2541 not symbol_new, for symbols holding expression values.
2542 * expr.h (make_expr_symbol): Move declaration here.
2543 * write.c (fix_new_exp): Handle O_add by creating an
2544 expression-valued symbol, and calling fix_new_exp recursively.
2545 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
2546 undefined symbol and a constant, fold the constant into the fixup,
2547 and refer to the undefined symbol directly. Then process the
2548 fixup again from scratch.
2549 (write_object_file): Before calling adjust_reloc_syms, make a pass
2550 through the symbol list trying to resolve values.
2552 * write.c (print_fixup): New routine, for debugging.
2553 (write_relocs): Call bfd_install_relocation. Deleted various
2554 hacks for working around problems with bfd_perform_relocation.
2556 * Makefile.in (VERSION): Update to 2.4.90.
2558 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2560 * Makefile.in (gasp.o): Depends upon config.h.
2562 * config/tc-mips.c: Include subsegs.h.
2563 (md_apply_fix): If an unconditional b or bal overflows, and we are
2564 not assembling PIC code, replace it with a j or jal.
2566 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
2567 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
2569 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2571 * write.c (write_relocs): Add file name and line number to
2572 as_fatal calls. Handle bfd_reloc_overflow case specifically when
2573 RELOC_EXPANSION_POSSIBLE.
2575 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2577 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
2578 here. Use them for deciding which PRINTF*LIKE macro definitions
2580 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
2581 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
2582 default definitions matching what we were doing before.
2583 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
2584 always use the varargs form if not using stdarg. It's safe to
2585 always use vfprintf, because libiberty will provide it if the
2586 native system doesn't. Also, always make format be const.
2587 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
2589 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

2602 (listing_newline): Check filename as well as line number when
2603 deciding whether to record it.
2604 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
2605 false (if defined) as well as checking for reg_section.
2606 (listing_listing): Iterate fetching lines while line number is too
2607 low, and we haven't run off the end of the input file.
2609 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
2611 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
2613 * ecoff.c (ecoff_generate_asm_lineno): check if
2614 current_stabs_filename is NULL before strcmp.
2615 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
2618 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2620 * config/ho-*.h: Now-unused files deleted.
2622 * symbols.c (copy_symbol_attributes): New function. Copies BFD
2623 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
2624 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
2625 zero. Don't call obj_frob_forward_symbol.
2626 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
2627 X_add_number is zero.
2628 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
2630 * config/tc-i960.c: Lots of whitespace, comment reformatting,
2632 (strchr): Don't declare.
2633 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
2634 md_estimate_size_before_relax, md_ri_to_chars,
2635 md_create_short_jump, md_create_long_jump.
2636 (brtab_emit): Use data_section, not SEG_DATA.
2638 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2640 * config/vms-conf.h: new file, manually derived from conf.in.
2641 * config-gas.com: use it, and eliminate obsolete "host.h".

2645 * config/tc-ppc.c (ppc_current_block): New static variable.
2646 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
2647 ppc_current_block. Don't move around any stab symbol, just those
2649 (ppc_bs): Set ppc_current_block.
2650 (ppc_es): Clear ppc_current_block.
2651 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
2652 from the csect of the enclosing block.
2654 * config/tc-mips.c (insns_since_cache_access): Remove.
2655 (append_insn): Remove setting of insns_since_cache_access, and
2656 special 4600 handling; it turns out not to be required.
2658 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2660 * config/tc-mips.c (md_shortopts): Remove E.
2661 (md_longopts): Add EB and EL.
2662 (md_parse_option): Handle -EB and -EL as separate options, rather
2663 than as a single -E option with an argument.

2670 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2672 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
2674 * configure.in: Test for remove, not delete. Fix cross-assembler
2676 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
2679 * read.c (pseudo_set, case O_symbol): If
2680 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
2681 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
2682 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
2684 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
2686 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
2687 many others): new macros; values obtained from "DSTRECRDS.SDL".
2688 * config/obj-vms.h (various): use them.
2689 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
2690 representation (only enum bitfields can avoid being bitstrings).
2691 (bitfield_suffix, setup_basic_type): new routines.
2692 (VMS_typedef_parse): use them. Now recognize bitfields of all
2693 integral types, not just type `int'. Caveat: the representation
2694 used for bitfields still does not work for objects placed in
2695 registers, and gcc's optimizer sometimes puts small structs there.
2697 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2699 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
2700 bit from const_flag.
2701 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
2702 (tc_frob_label): define this to call vms_check_for_special_label,
2703 and declare the latter.
2704 * config/obj-vms.c (vax_g_doubles): declare this file-scope
2706 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
2707 (vms_check_for_special_label): new routine (tc_frob_label).
2708 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
2709 and `gcc2_compiled.' labels; they won't reach here any more.
2710 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
2711 double', use `vax_g_doubles' flag to select type of double.
2712 (VMS_write_object_file) [traceback setup]: don't pass symbols
2713 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
2714 and TBT_Routine_End functions.

2718 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
2719 S_GET_VALUE() to avoid many repeated function calls.
2720 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
2721 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
2722 gets requested. [All the HACK_DEC_C_STARTUP code appears to
2723 be obsolete; gcc does it automatically for vms target. It's
2724 also misnamed, because it is for the "VAX C" run-time library,
2725 not the newer "DEC C" one which has much different startup code.]
2726 {various}: use `S_SET_xxx(symbol,new_value)' rather than
2727 `S_GET_xxx(symbol) = new_value'.
2729 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2731 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
2732 not &bfd_abs_section.
2734 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2736 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
2738 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
2740 * expr.c (expr): Don't reduce the difference of two symbols in the
2741 same frag if the symbols are not in normal sections.
2743 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
2744 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
2745 (obj_attach_unwind_info): Do not define. Not needed anymore.
2746 * config/tc-hppa.c: Delete whitespace at EOL.
2747 (struct hppa_fix_struct): Delete fx_unwind field and all references.
2748 (fix_new_hppa): Last arg is now a pointer to an int. Do not
2749 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
2750 fixups, store 32bits of unwind information in the fx_addnumber
2752 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
2753 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
2754 pointer to 32 bits of unwind info.
2755 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
2756 pointer to the dummy symbol; set the addend field to fx_addnumber.
2757 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
2758 rather than &bfd_XXX_section.
2760 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2762 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
2763 value by one; discard adjustments previously being made. From
2766 VMS- and Vax-related changes from Pat Rankin:
2767 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
2768 * vmsconf.sh: no longer have make-gas.com echo text about needing
2769 to modify the gcc-vms driver when intending to use with gcc 1.x.
2770 * as.c (parse_options): suppress 'v' from std_short_options and
2771 eliminate VMS-specific conditional initialization;
2772 [default case]: check for '-v' if md_parse_options doesn't recognize
2774 [default case, #if VMS]: check for filename argument when '-v' seen;
2776 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
2777 for O_big literal operands (double floats and long long ints);
2778 [VMS, md_shortopts]: add second colon after 'v';
2779 (md_parse_options) [VMS, case 'v']: check for argument, so
2780 caller can handle `-v' w/o arg.

2784 * config/obj-coff.c (do_relocs_for): If TC_KEEP_FX_OFFSET
2785 is defined, put the tx_offset into the r_offset.
2786 * config/tc-sh.c (line_comment_chars): Add #
2787 (tc_reloc_mangle): Deleted.
2788 * config/tc-sh.h (TC_KEEP_FX_OFFSET): Define.

2819 * as.h (EXIT_SUCCESS, EXIT_FAILURE): Moved here.
2820 * as.c: ...from here.
2821 (parse_args): Use them always.
2822 (main): Use exit rather than return.
2824 * Makefile.in (*_FOR_TARGET, INSTALL_XFORM, install, uninstall):
2825 Rewrite handling of program_transform_name.
2827 * configure.in: Test for functions unlink and delete.
2828 * as.h: If unlink isn't available but delete is, define unlink to

2832 * gdbinit.in: New file, created from old .gdbinit.
2833 * .gdbinit: Deleted.
2834 * aclocal.m4 (GAS_GDBINIT): Deleted.
2835 * configure.in: Don't use it. Instead, generate .gdbinit from

3776 * read.c (emit_expr): Use memset to zero out memory, rather than
3777 going through md_number_to_chars. This permits handling symbolic
3778 arguments when the size is larger than sizeof (valueT), if
3779 TC_CONS_FIX_NEW is prepared to handle the case (as it is on MIPS).
3781 Fri Jun 3 12:50:13 1994 David J. MacKenzie (djm@rtl.cygnus.com)

3830 m68040_control_regs, m68060_control_regs): New arrays.
3831 (control_regs): New pointer.
3832 (m68k_ip): Use control_regs instead of testing CPU every time.
3833 Use last_movec_reg too. In error messages, handle 68060, and
3834 print 68060 for mfloat, too.
3835 (m68k_init_after_args): Handle "68060". Use m68040up for making
3836 m68851 choice. Set control_regs.

3841 [DIFF_EXPR_OK]: Do conversion to pc-relative for difference, even
3842 if pcrel is already set.
3844 * read.c (potable): Add this_gcc_requires_the_gnu_assembler in all
3845 lower-case, in case we're ignoring case of opcodes in the input

3851 * config/tc-alpha.c (machine): New variable.
3852 (load_insn): New macro.
3853 (load_insn_table): New function.
3854 (md_begin): Call load_insn_table, once for basic instructions and
3855 once for appropriate PAL instruction table.

3904 VMS debugger now recognizes `long long' variables correctly.
3905 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
3906 for gcc2's predefined types "long double" (same as double, as
3907 per gcc's current state), "long long int", "long long unsigned
3908 int", and final `otherwise' case (to avoid uninitialized type
3909 and size fields). [caveat: predefined types "complex int",
3910 "complex float", "complex double", and "complex long double" are
3913 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
3914 of 0, because the latter indicates success rather than failure
3915 when passed to `exit' or return from `main' compiled by gcc2.

3918 hardcoded `0xa3's with macro DBG_S_C_ADVANCED_TYPE from obj-vms.h.
3919 (VMS_typedef_parse): eliminate redundant if-then-else when
3920 allocating new symbol entry and linking it to VMS_Symbol_type_list.
3922 Tue May 17 20:47:31 1994 Pat Rankin (rankin@eql.caltech.edu)
3924 * config/obj-vms.c (Write_VMS_MHD_Records): don't try to interpret

4150 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum
4152 (make_pcrel_absolute) [NO_PCREL_RELOCS]: New function.
4153 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
4154 R_DIR16, and R_DIR32 relocs.
4155 * config/tc-m68k.h [TE_APOLLO] (COFF_MAGIC, COFF_AOUTHDR_MAGIC):
4156 Use Apollo versions.

4206 with the preceding instruction even if .set nobopt has been seen.
4207 .set nobopt actually controls whether to bring up an instruction
4208 from the branch target, which gas does not currently support.
4210 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4212 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

4273 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
4275 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
4277 * vmsconf.sh: In generated file, get ".obj" suffix right, build

4299 argument, the reloc type.
4300 (load_register): Pass reloc type to macro_build for 'u'.
4301 (macro): Likewise. For M_LA_AB permit a difference expression
4302 when generating embedded PIC code between an arbitrary symbol and
4303 a symbol in the .text section.

4345 (hppa_tc_symbol): Likewise.
4347 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
4348 elf_tc_make_sections stuff. It was there to support PA braindamage
4349 which has been fixed, and in the case of elf_tc_make_sections is
4350 redundant with elf_tc_final_processing.
4352 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4370 don't spew remainder of input file in error message.
4371 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error

4384 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
4385 flag rather than signedp field. Only permit extended range if
4386 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
4387 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
4389 * config/tc-ppc.c (ppc_size): New static variable.
4390 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
4391 (md_begin): If an instruction has a size specific flag set, only
4392 add it if we are assembling that size.

4396 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
4397 cross section PC relative relocs right for COFF and ELF.
4399 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4401 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

4407 the type of symbol set symbols which happen to be in the absolute
4408 or undefined section.

4412 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
4413 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),

4418 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
4419 involving a function symbol which is not a plabel to zero.
4420 (md_apply_fix): Never pass a function symbol to field_adjust.

4424 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
4425 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
4427 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
4428 branch with an instruction that uses $at, in case the branch is
4430 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
4431 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
4432 to make it pcrel_offset.
4433 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
4434 reloc->address; another gruesome hack to get gas reloc handling to
4437 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4439 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
4442 (emit_insn): New function.
4443 (md_assemble): Call it.
4444 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
4446 (lituse_pending): New variable. Set by anything that generates a
4447 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
4448 tested by code that might want to emit a LITUSE reloc.
4449 (emit_unaligned_io): New function. Currently calls md_assemble,
4450 but it should eventually be converted to generate the insn itself
4451 and call emit_insn directly.
4452 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
4453 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
4454 emit_bis_r): Likewise.
4455 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
4456 (alpha_ip, label get_macro): Don't emit the final instruction if
4458 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
4459 unaligned memory access macros.
4460 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
4461 the value can't be resolved.
4463 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4465 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
4466 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
4467 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
4469 (mips_force_relocation): New function.
4470 (md_apply_fix): Set fixP->fx_done appropriately.

4479 * config/tc-mips.c (enum mips_pic_level): New enum.
4480 (mips_pic): Change from int to enum mips_pic_level. Change all
4481 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
4482 (load_address): Handle EMBEDDED_PIC.
4483 (macro): Handle EMBEDDED_PIC in all PIC cases.
4484 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
4485 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
4486 -non_shared to use NO_PIC (this is how the Irix 5 assembler
4487 works). Do not permit -G with SVR4_PIC.
4488 (s_abicalls): Warn if -G was used, and force -G 0.
4489 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
4490 anything but a.out, not just for ELF. For ECOFF, don't generate a
4491 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
4493 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
4495 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4497 * config/tc-hppa.c (create_new_space): Use ints, not chars as
4498 parameters to avoid losing when compiling with HP CC.

4501 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4503 * Makefile.in (config-stamp): If `defs' is defined, emit a
4504 preprocessor directive to create a macro named by this value into
4505 config.new; don't explicitly go for BFD_ASSEMBLER.
4506 * configure.in: Define `defs', not `BFDDEF'. Set it to
4507 MANY_SEGMENTS for any obj-coffbfd target.
4508 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
4509 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
4511 (LOCAL_LOADLIBES): Deleted.
4512 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
4513 * config/m88kcoff.mt (TDEFINES): Ditto.
4514 * config/ebmon29k.mt: Deleted.
4515 * config/h8300hds.mt: Deleted.

4539 bfd_set_symtab is called.
4540 (dump_section_relocs): Note whether a symbol is a section symbol
4542 (adjust_reloc_syms): For now, always supply an absolute symbol for
4543 fixups without symbols but not yet `done'. Use section_symbol to
4544 get the symbol, instead of going directly for abs_symbol.
4545 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
4546 reloc is not a section symbol and is not in the symbol table.
4547 (set_symtab): New function, broken out from write_object_file.
4548 Counts symbol table instead of relying on an earlier count.
4549 (write_object_file): Call set_symtab, but do it after potentially
4550 invoking the *_frob_file macros. Don't bother counting symbols.
4551 Call symbol_remove, instead of expanding it in place. Moved the
4552 conditionalized `object_file_size' declaration down to
4553 conditionalized block where it's used. When using the absolute
4554 symbol for a fixup without a symbol, set sy_used_in_reloc.
4555 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
4556 the correct symbol for the absolute section.
4558 * subsegs.c (section_symbol): Use symbol_new instead of
4559 symbol_make, since we may want it to go into the symbol table.
4560 Make the new symbol have internal linkage. If
4561 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
4562 symbol with the newly created GAS symbol.
4563 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
4564 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

4569 (in_signed_range): New function.
4571 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
4572 (sparc_ip, label "immediate"): Reject constants for pcrel
4573 instructions only if the relocation type indicates a "call"
4574 instruction and the offset is within range of a "jmpl %g0". If
4575 it's not in range, use the absolute section symbol plus an offset.
4576 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
4578 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
4580 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
4583 * configure.in: Eliminated all targets using obj-coff but not
4584 defining BFD_ASSEMBLER; I think all such targets that are
4585 supported will be matched by real CPU-OS combinations earlier in
4587 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
4588 some comments about the dpx2 configuration, but left it disabled,
4589 since it couldn't be reached before.
4590 (target a29k-amd-ebmonold): Deleted.
4592 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4600 the 'j' operand if there are no further alternatives for this
4603 * config/obj-coffbfd.c (adjust_stab_section): Initialize
4604 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
4605 is not SEG_UNKNOWN rather than checking whether it is >= 0.
4607 * config/tc-mips.c (mips_align): Take new argument, label, and use
4608 it instead of global insn_label.
4609 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
4610 call to mips_emit_delay and pass it to mips_align.
4612 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4614 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
4616 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
4617 argument to a .callinfo directive. Don't loop forever on errors.
4619 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
4620 use pre-defined registers as arguments.

4624 * write.c (write_object_file): Check both S_IS_LOCAL and
4625 S_IS_EXTERNAL when deciding whether to discard a symbol.
4627 * config-gas.com: Scan Makefile.in, not version.c, for current

4632 values to reduce number of lookups with S_GET_VALUE. Skip debug
4633 symbols to avoid "a really nasty bug". (From Holger Teutsch,
4634 holger@botbso.rhein-main.de.)
4635 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
4636 field. (Also from Holger Teutsch.) Watch for a would-be register
4637 mask that spans frags.
4639 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
4640 this_base, not line_base. (Patch from Andreas Arens,
4641 ari@obelix.av.rwth-aachen.de.)
4643 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
4644 look local if they're exported or undefined. Used to be done for
4647 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
4648 Get it from the looked-up symbol, instead of using the string from
4649 the input stream, which is no longer null-terminated.
4650 (LEX_PCT): New macro, defaults to 0.
4651 (lex_type): Use it for `%'.
4653 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
4654 (vip_op): Now static, and returns void. Callers changed. Added
4656 (vip): Ditto. Call as_fatal directly if a program bug is

6288 Delete dead code. Simplify.
6289 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
6290 applied are in range. Use bfd_put_32 rather than inserting each

6369 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
6370 standard hpux include files to pick up various function decls.
6372 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

6384 so GAS can attach unwind descriptor information to a BFD symbol.
6385 * config/tc-hppa.c (fix_new_hppa): If necessary attach unwind
6386 descriptor information to the BFD symbol.
6387 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

6405 of interest to the linker. ENTRY/EXIT relocations for SOM are
6406 an example of marker relocations.
6407 * write.c (write_relocs): Instead of assuming size of a relocation
6408 is 4 bytes, pick up the size from relocation itself.

6438 pass new argument for i, j and o cases.
6439 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

6660 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
6661 the table, require that the one without bit 0x1000000 set come

6663 opcode table already meets these constraints.
6664 (machine_ip): When handling case 'i' or 'A', make sure that the

6772 OPTIONAL_REGISTER_PREFIX if either is already defined.
6774 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
6776 * configure.in: Set bfd_gas for all sparc targets. Added facility
6777 for keeping or rejecting configurations still under development;
6778 default is to assume production environment, and reject configs
6779 still being worked on. Mark Elf configurations (except sparc and
6780 i386) as developmental. Deleted cases matching some generic names
6781 in favor of more specific names. (E.g., when we get Alpha

6798 through inclusion of tc-hppa.h. Delete all forward declarations
6799 for functions only used within tc-hppa.c, likewise for structures,
6800 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
6801 conditional code in a few small places.
6803 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
6804 structures, global variables, forward declarations together.

6806 conditional code -- try to group conditional code together
6807 into a few places. Make all functions and variables which
6808 are only used within tc-hppa.c static. PARAMize all functions.
6809 Add comments to functions. Delete unused functions, variables,
6810 #defines, etc. Delete unused members within structures. Delete
6811 ldil;ble hacks -- it is believed they were installed to work
6812 around old gas bugs. Avoid using mixed case for local
6813 functions, variables, and structures. Fix formatting problems
6814 not found by GNU-indent. Add FIXME notices for things which
6815 should be worked on the near future. Delete lots of old
6816 useless (1.36 PA-SOM) code.
6818 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
6819 field of the fixS structure. Needed to build unwind

6845 a multiple of the section alignment rather than always a
6848 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

6895 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
6897 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
6898 ELF, since the ELF object format does not have these type of
6899 relocations. Change the abort into as as_bad and return
6900 BFD_RELOC_NONE to silence compiler warnings.
6901 (md_assemble): Keep track of the instruction size. Allow white
6902 space between the $ and the constant for compatibility with older
6903 gases and other assemblers.

7910 Fri Jul 23 13:09:44 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
7912 * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
7913 are also magic, and have special default flag settings.
7914 (obj_elf_frob_symbol): Since the return value from this function
7915 isn't used, don't bother calling obj_elf_write_symbol_p, since it
7916 doesn't accomplish anything else.
7918 * config/tc-sparc.c (md_section_align): Round up section size only
7921 * symbols.c: Don't define DEBUG by default.

7927 * expr.c (expr): Don't let absolute_section override
7928 undefined_section for the return value.
7930 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
7931 pseudo-op with a poc_handler field of NULL, ignore it and treat it
7932 as an instruction instead.
7933 * config/tc-m88k.c (md_pseudo_table): Add "set" with a NULL
7936 * config/tc-h8500.c (md_begin): Use a local variable when

7948 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
7949 case to set obj_format=elf. Must go before i386-*-sysv* case that
7950 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
7951 *-*-solaris case, and move to before *-sysv* case that wants to
7952 set obj_format to coff.

7978 * Extensive changes to permit symbols to contain any expression
7979 type and to delay the computation of the expression until the
7980 value is actually needed. This permits setting symbols to values
7981 calculated based on object code size. Expressions were changed to
7982 no longer be in a section, to stop the overloading of segment and
7983 expression type that previously occurred.
7985 * as.c (big_section, pass1_section, diff_section, absent_section):
7987 (expr_section): Added (used for dummy symbols which hold

8071 (previous_section, previous_subsection): New vars.
8072 (obj_elf_section): Save current place in case DWARF code wants us
8073 to pop back to it. Handle unquoted section name as well as quoted
8074 section name. Don't crash on invalid strings.
8075 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
8078 * config/obj-elf.h: Don't include struc-symbol.h.

8187 sy_resolved and sy_resolving single bit fields.
8188 * symbols.c (symbol_new): Don't initialize sy_forward field.

9332 process relocs if there aren't any relocs to process. Avoids
9333 malloc/free bug on SCO too.

9387 dropping a space immediately following an identifier.
9388 * expr.c, write.c: Rewrote assert expressions to not use multiple
9389 lines; I don't think that can be done portably.
9390 * config/tc-mips.c (macro): Use $AT if target register is zero in
9391 load instruction, which it can be for a floating point load.

9465 prototypes for all static functions. Moved existing minimal
9466 debugging format support info #ifndef OBJ_ECOFF blocks.

9515 * make-gas.com: Find obstack.obj if it's not in the current
9517 * read.c (s_ignore): Don't declare is_end_of_line. It's
9518 redundant, and triggers a VMS gcc compiler bug.
9520 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
9521 current segment as an argument. (Ignored in all cases but VMS.)
9522 All callers and definitions changed.

9576 constants are accepted, but symbolic values are not. GCC will not
9577 generate the latter currently.
9579 * frags.c (frag_init): New function.
9580 (zero_address_frag, bss_address_frag): Now initialized at run
9582 * as.c (main): Call frag_init.

9830 (s_xword): New function.
9832 * config/tc-sparc.c (architecture_requested, warn_on_bump,
9833 md_relax_table): Use default zero initialization.
9834 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
9835 latter, instead of selecting with preprocessor conditionals.
9837 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9839 * configure.in: recognise all sparclite variants

9847 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
9849 * expr.c (operand): If character other than comma or newline is a
9850 logical end-of-line character, use the newline case.
9851 From Eric Youngdale:
9852 (operand): Set X_add_number field for floating-point numbers.
9853 (operand): Treat zero byte as end-of-operand.
9855 * configure.in (per-target): Look for with_bfd_assembler option.
9856 For now, only accept "no", until the merge is done.
9858 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
9859 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
9860 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
9861 * read.c: Finish conversion to S_* macros in the VMS only
9862 parts of the program. Add "const" modifier to hex_value.

9865 * expr.c: Add "const" modifier to hex_value.
9866 * symbols.c: Finish conversion to S_* macros in the VMS only
9867 parts of the program. Add "const" modifier to
9868 md_[long,short]_jump_size. Remove declaration of const_flag
9869 (which will be declared in obj-vms.h).
9870 * write.c: Add "const" modifier to md_[long,short]_jump_size.
9871 Fix arguments to VMS_write_object_file.
9872 * config-gas.com: New file. Script for VMS systems to set up the
9873 configuration to build gas for VMS, and create config.status.
9874 * make-gas.com: Redone to work with new scheme.
9875 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
9877 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
9878 will swap bytes if needed on a big endian system. Use throughout
9880 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
9881 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
9882 types of malformed stabs. Change parsing algorithm so that we are
9883 more certain of having all of the information that we need on hand.
9884 * obj-vms.c (final_forward_reference): New function, used to help
9885 resolve the data types of as many struct elements as possible
9886 when some part of the struct is not fully defined by the compiler.

9889 * obj-vms.c (VMS_write_object_file): Define all vtable psects
9890 as symbols as well in the object file. Look for external functions
9891 that start with "__vt.", and turn them into variables, since the
9892 g++ compiler is incapable of doing this.
9893 * tc-vax.c: Add '1' option for backward compatibility with older GCC
9895 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
9896 * input-scrub.c (as_where): Fix bug where as would crash if we did not
9897 have the name of the source file yet.
9898 * config/ho-vms.h: define HO_VMS, not HO_VAX.
9900 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
9902 * read.c (s_data): Always use "data_section", since it'll map to
9903 SEG_DATA or SEG_E1 if needed.
9904 (s_lcomm): Likewise with bss_section.
9905 (s_fill): Use memset, not bzero.
9907 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

9926 otherwise, use seg_name array.
9927 (seg_name): Declare only if not BFD_ASSEMBLER.
9928 (section_alignment): Declare only if not BFD_ASSEMBLER.
9929 (big_section, reg_section, pass1_section, diff_section,
9930 absent_section, text_section, data_section, bss_section): If
9931 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
9932 mapping to segT enum values.
9933 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
9934 if these are used or defined, if BFD_ASSEMBLER.
9935 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
9936 subseg_new split into two functions.
9937 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
9939 * as.h (volatile): Don't define if already defined.
9940 (had_errors, had_warnings): Provide prototypes for ANSI C even if
9942 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
9943 declare with format attribute for -Wformat checking.
9945 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
9947 * app.c, config/tc-*.c: Don't include read.h, since it is already

9951 <mtranle@paris.intellicorp.com>.
9952 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
9953 obj_format coffbfd and gas_target i386coff for target.
9954 (i[34]86-*-isc*): New host (uses sysv).
9955 * config/i386aix.mt: Removed (no longer used).
9956 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
9958 (LDFLAGS): Added, defined as -shlib.
9959 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
9960 * config/te-sco386.h (LOCAL_LABEL): Don't define.
9961 (DOT_LABEL_PREFIX): Define.
9962 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
9963 name rather than L0\001.
9964 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
9966 * symbols.c, symbols.h (local_bss_counter): Removed.
9967 * write.c (write_object_file): bss no longer uses
9968 local_bss_counter. Pass correct data and bss size to
9969 VMS_write_object_file.

9975 (size_section): Restored sanity check.
9976 (do_relocs_for): Base section address on s_paddr rather than
9977 computing it. Adjust a29k R_IHIHALF special case to account for
9978 section paddr (used to require paddr to be zero). If there are no
9979 reclos, set s_relptr to 0. Set relocation size in object_headers.
9980 (fill_section): Always set s_vaddr here, removing
9981 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
9982 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
9983 Set STYP_INFO for .comment.
9984 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
9985 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

9987 H_{SET,GET}_* macros.
9988 (do_linenos_for): Set lineno size in object_headers.
9989 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
9990 set s_vaddr here. If string_byte_count remains 4, set it back to
9991 0, and only write strings out if there are some. Call
9992 fill_section before do_relocs_for and do_linenos_for.
9993 (obj_coff_section): Handle optional quoted second argument giving
9994 section characteristics.
9995 (obj_coff_bss): Added to handle .bss.
9996 (obj_coff_ident): Added to handle .ident (puts string in .comment

10016 (do_scrub_next_char): For \", return " not '.
10017 (symbol_chars): Now const.
10019 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
10020 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
10022 * config/obj-coff.h: Don't use #elif.
10024 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
10025 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
10027 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
10029 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

10051 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
10052 using ZERO_BASED_SEGMENTS.
10053 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
10054 never set segment address for SEG_E2 (.bss) and don't write out
10055 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
10056 (obj_coff_endef): Don't merge labels or symbols awaiting forward
10057 definitions, and don't merge tags with non-tags. Check for .bf
10058 rather than just checking whether the second character is b and
10059 the third character is f.
10060 (obj_coff_val): gcc can generate values which we don't handle
10061 correctly; discard information for now, since it only affects the

10286 * Support for i386-sysv.
10287 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
10288 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
10289 be used to set them all to zero as was done before.
10290 (fill_section): segment addresses now set in write_object_file.
10291 (fill_section): Don't set STYP_NOLOAD for .bss section.
10292 (fixup_segment): 386 uses strange common symbol format.
10293 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
10294 compatibility with SVR3.2 linker.
10295 * configure.in: i386-sysv and i386-sco use coffbfd.
10297 * app.c (do_scrub_next_char): discard whitespace after a label.
10299 Sat Oct 10 12:33:45 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

10306 fix i960+non-bfd coff bit rot.
10307 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
10308 support for C source listings. (obj_coff_endef): look in the right
10309 part of the symbol for the symbol name

10314 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
10316 * configure.in: recognize i386-*-bsd emulation.

10327 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
10329 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
10330 #elif, since it is not supported by old compilers.
10331 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
10332 couple of expressions in tc-m68k.c.
10334 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10336 * read.c (cons): If NO_RELOC is defined, use it.

10342 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
10343 local labels to start with a .) and set REGISTER_PREFIX to %.
10344 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
10346 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

10357 * listing.c (debugging_pseudo): Add stabs and stabn as things to
10360 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
10362 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
10363 sections starting from zero, rather than making them consecutive.
10364 This makes subsequent reloc calculations easier, esp if the object
10365 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
10366 allocate lcomm in .data rather than in .bss. It seems that some
10367 tools can't cope with a non-zero sized bss before linkage.

10371 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10372 throughout. That enum no longer means what we thought it meant.

10375 "-mno-688[58]1" options.
10377 * tc-m68k.c: Added CPU32 support.
10379 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

10390 * Makefile.in (install): if $(tooldir) exists, install as in
10393 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10395 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10396 .word is < -32768 or > 32767. The -J flag causes the error to be
10397 ignored. This is to catch over-sized switches generated by gcc on
10398 systems which don't support the broken .word hack.
10399 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10400 write.c (fixup_segment): check for signed .word overflow if
10401 WARN_SIGNED_OVERFLOW_WORD.
10403 * write.c (fixup_segment): fixed missing parens in expression
10404 checking for byte or word overflow.
10406 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

10418 * tc-i386.h : new coff defines
10420 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
10422 * input-scrub.c (input_scrub_push): call input_file_begin, not
10424 messages.c (as_perror): print ": " between the passed in error and
10425 the strerror, like perror does.
10427 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

10434 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
10435 Motorola and MIT syntax; gas can now assemble either type of
10437 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
10438 From Steve Chamberlain:
10439 m68kcoff.mt: for m68k COFF.
10440 obj-coffbfd.c: (fixup_mdeps) added
10441 (size_section) removed bad sanity check
10442 (fill_section) added rs_machine_dependent case
10443 (write_object_file) call fixup_mdeps
10444 (fixup_segment) set fx_subsy to 0.
10445 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
10447 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
10450 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

10474 tc-i960.c (md_ri_to_chars): Always output bout object file in
10475 little endian byte order (used to use endianness of host).
10477 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10479 * config/tc-m68k.c (init_table): Now const. Always include 68851
10480 data, so that "bc" is available to 68040 cache instructions.
10481 Added "tt0", "tt1", and 68ec030 variants.
10482 (md_assemble): Complain if 68000 (only) and 68881 are specified.
10483 (enum _register): Added TT0, TT1.
10484 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
10485 line number correctly in "internal error" messages. Don't print
10486 architecture-mismatch message for operand errors.

10506 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
10507 so that we can assemble hand-written libgcc code.
10509 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10511 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
10512 has already been formatted (but may still contain %-characters).
10513 (as_bad): Likewise.
10515 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
10517 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
10518 written with indirection on the last two operands, which can be
10519 either data or address registers. Added a new operand type 'r'
10520 which accepts either register type. Added '(' to notend stuff in
10521 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

10568 being used with args swapped, causing occasional lossage when
10569 refilling buffers after an include file.

10632 (md_assemble): If no CPU has been set (even if FPU/PMMU
10633 characteristics have been), default to 68020. Don't need extra
10634 quotes around error string.

10746 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10748 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
10749 calc the base of relocs correctly.
10750 * tc-a29k.c (parse_operand): allow expressions to be in any section.
10752 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
10754 * as.c, write.c: use -K rather than -k for the broken word warning
10757 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
10759 * Makefile.in: do not print recursion lines.
10761 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10763 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
10765 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
10767 * write.c (write_object_file): For b.out format, round up section
10768 start addresses to match required alignment.
10770 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
10772 * Makefile.in (install): Install into $(tooldir)/bin, since that's
10773 where gcc looks for it.
10775 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
10777 * Makefile.in: Changed some lines to be less confusing for some
10780 * input-file.c: Conditionalize on _IOFBF, not VMS.
10782 * read.c, write.c: Change a series of ifdef/elif to
10783 ifdef/else/ifdef etc.
10785 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
10787 * symbols.c (fb_label_init): fix sizeof to memset.
10789 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
10791 * Makefile.in: install the man page.
10793 * Makefile.in: pass down MAKEINFO explicitly on info.
10795 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
10797 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10799 * flonum-const.c: renamed flonum-konst.c to stop dos name
10802 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
10804 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
10805 tc-m68k.h to te-sun3.h.
10807 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
10809 * configure.in: vxworks68 gets te-sun3.h.
10811 * expr.c: remove limitation that local_labels_dollar or
10812 local_labels_fb must be < 10.
10814 * symbols.c: remove local_labels_dollar, replace with a function
10815 interface for a sparse array. All users adjusted.
10817 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
10819 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10821 * doc/Makefile.in: commented out line for building as-all.texinfo.
10824 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
10826 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
10828 * Makefile.in: added check target.
10830 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10832 * Makefile.in: added tooldir and program_prefix.
10834 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
10836 * write.{c,h} (fix_new): Make these declarations consistent.
10838 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
10840 * Makefile.in (strerror.o): Add rule so that broken Sun make can
10843 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
10845 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
10847 * expr.c (operand): if can't work out what sort of operand it is,
10848 then look through FLT_CHARS for a hint.
10850 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
10852 * Makefile.in, configure.in: removed traces of namesubdir,
10853 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10854 copyrights to '92, changed some from Cygnus to FSF.
10856 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
10857 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10858 copyrights to '92, changed some from Cygnus to FSF.
10860 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10862 * expr.c: If an expression is single comma, then return with
10863 SEG_ABSENT rather than an error - since the sparc front end does
10864 really strange things with things like fbge,a
10866 * as.h: include bfd.h if using many sections
10867 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
10868 local labels didn't work.
10869 * listing.c (list_symbol_table): don't core dump when there's no
10871 * write.c, write.h: call fix_new with the right number of args on
10873 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
10876 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10878 * app.c: MRI compatibility - allow single quote to start a string.
10879 * as.c: fix typo recently introduced.
10880 * as.h : Don't include aout/reloc.h - it's not right for COFF!
10881 * expr.c: Much rewriting, to accomodate MRI syntax for
10882 expressions. Also easier to read now.
10883 * listing.c: Put back defuns
10884 * read.c: modified to accept MRI syntax, put back listing pseudo
10885 ops so that an assembler built with NO_LISTING ignores list ops
10887 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
10888 machine is a SPARC or a 29K.
10889 * config/obj-aout.c: added s_sect pseudo op
10890 * config/obj-coffbfd.c: lints, set the filehdr flags right and
10891 fill in the timestamp.
10892 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
10893 anymore, define all the relocs which the tc-<x> bit will use so we
10894 can translate from them to the coff types.
10895 * config/tc-a29k.c: reloc_type isn't ane enum any more
10896 * config/tc-m68k.c: Added NO_RELOC definition.
10898 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10900 * Makefile.in: put header files before C source for TAGS; remove
10901 references to non-existent syscalls.h.
10903 * read.c, write.c subsegs.c: back out the .bss changes.
10905 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
10907 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
10909 * a.out.h: removed.
10911 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
10913 * symbols.c (local_label_name): symbols now start with ^A.
10915 * read.c, subsegs.c, write.c obj-coff.c: added handling of
10916 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
10917 generate these sections. .align: will use NOP_OPCODE or 0
10918 for padding. This is just for being nice to the
10921 * expr.c (operand): changed to generate local label "\001L0"
10922 starting with a ^A so that it is recognized as a local label.
10924 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
10926 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
10927 i/o opcodes - inb, inw, outb and outw. string manipulation with
10928 att syntax - scmp, slod, smov, ssca, ssto.
10930 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
10931 to just after .file .
10933 In obj_crawl_symbol_chain() where it tries to put the external
10934 symbols apart, with the condition:
10935 (!S_IS_DEFINED(symbolP) &&
10936 !S_IS_DEBUG(symbolP) &&
10937 !SF_GET_STATICS(symbolP))
10938 it was moving too many symbols out. So I switch it back to the
10940 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
10942 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
10943 so that we don't use the F_RELFLG which make the linker complain
10944 that somebody has stripped the relocation info.
10946 Also, the AIX ld program require that the relocation table
10947 is sorted by r_vaddr like the standard ATT assembler does.
10949 [he also changed the sizeof(struct ...)'s into the coff
10950 style FOOSZ macros. I'm not sure this is right, but I can't
10951 remember why. xoxorich.]
10953 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
10955 * Makefile.in, configure.in, doc: use the doc. Build it, install
10958 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
10960 * read.c: white space and comments only.
10962 * configure.in: use the new atof-ns32.c for ns32k.
10964 * write.c: comment change only.
10966 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
10967 aren't yet integrated.
10969 * tc-i860.[hc]: blew off the dust. Something must still be done
10970 about conflicting relocation types.
10972 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
10975 * tc-i960.c, tc-sparc.c: white space and comments only.
10977 * tc-a29k.h: delete duplicate macro definition.
10979 * new file atof-ns32k.c copied from hack's last unreleased gas.
10981 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
10983 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
10986 * nearly everything. flush ChangeLog, package as gas-1.92.1.
10987 ChangeLog's prior to this are sketchy at best. I have logs.
10988 They just aren't ChangeLogs.
