2398 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
2400 (i386_operand): Don't look up section symbol for
2402 (reloc): Always permit return of 8- and 16-bit relocation types.
2403 Add a space after "pc-relative" in the error message.
2404 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
2405 BFD_RELOC_386_GOTOFF relocs.

2409 (TC_VALIDATE_FIX): New macro -- call it.
2410 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.
2412 * as.h: If __STDC__ is not defined and varargs.h is available, use

2416 referring to PLT entries.
2417 * write.c (fix_new_internal): Initialize fx_plt to zero.
2418 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
2419 Don't adjust fx_offset by frag address, since S_GET_VALUE now
2420 includes the frag address.
2421 (fixup_segment): Changed local var PCREL to type int, added PLT.
2422 If PC-relative fixup refers to a PLT entry for a symbol in the
2423 current section, don't reduce it.
2425 * write.c (adjust_reloc_syms): Exit loop through a label. If
2426 DEBUG5 is defined, print out each fixup before and after
2428 (fixup_segment): If DEBUG5 is defined, print out each fixup before
2429 and after processing.
2430 (print_fixup): Added prototype. Show address on first line. Show
2431 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if
2432 NEED_FX_R_TYPE is defined.

2445 Show fx_r_type and fx_addsy fields.
2447 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2449 * configure.in: Set bfd_gas for all sparc targets in one place,
2450 instead of separately for each. Correctly handle user-supplied
2451 "--enable-bfd-gas" option.
2453 * gdbinit.in: Move "break abort" to end, in case gdb complains.
2455 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:

2459 processing if add_symbol is undefined or in expr_section.
2460 (resolve_symbol_value, case O_add): For symbol plus
2461 constant-valued symbol, convert to O_symbol and re-reduce.
2462 (S_GET_VALUE): If symbol needs resolving, resolve it.
2463 (indent_level): No longer static.
2464 (print_symbol_value_1): Don't print frag address if it matches
2465 zero_address_frag. Don't print "resolving" if already resolved.

2468 (print_expr_1): Fix whitespace before printing X_add_number.
2470 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
2471 not symbol_new, for symbols holding expression values.
2472 * expr.h (make_expr_symbol): Move declaration here.
2473 * write.c (fix_new_exp): Handle O_add by creating an
2474 expression-valued symbol, and calling fix_new_exp recursively.
2475 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
2476 undefined symbol and a constant, fold the constant into the fixup,
2477 and refer to the undefined symbol directly. Then process the
2478 fixup again from scratch.
2479 (write_object_file): Before calling adjust_reloc_syms, make a pass
2480 through the symbol list trying to resolve values.
2482 * write.c (print_fixup): New routine, for debugging.
2483 (write_relocs): Call bfd_install_relocation. Deleted various
2484 hacks for working around problems with bfd_perform_relocation.
2486 * Makefile.in (VERSION): Update to 2.4.90.
2488 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

2492 * config/tc-mips.c: Include subsegs.h.
2493 (md_apply_fix): If an unconditional b or bal overflows, and we are
2494 not assembling PIC code, replace it with a j or jal.
2496 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
2497 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
2499 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2501 * write.c (write_relocs): Add file name and line number to
2502 as_fatal calls. Handle bfd_reloc_overflow case specifically when
2503 RELOC_EXPANSION_POSSIBLE.
2505 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2507 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
2508 here. Use them for deciding which PRINTF*LIKE macro definitions
2510 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
2511 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
2512 default definitions matching what we were doing before.
2513 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
2514 always use the varargs form if not using stdarg. It's safe to
2515 always use vfprintf, because libiberty will provide it if the
2516 native system doesn't. Also, always make format be const.
2517 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
2519 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

2532 (listing_newline): Check filename as well as line number when
2533 deciding whether to record it.
2534 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
2535 false (if defined) as well as checking for reg_section.
2536 (listing_listing): Iterate fetching lines while line number is too
2537 low, and we haven't run off the end of the input file.
2539 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
2541 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
2543 * ecoff.c (ecoff_generate_asm_lineno): check if
2544 current_stabs_filename is NULL before strcmp.
2545 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
2548 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2550 * config/ho-*.h: Now-unused files deleted.
2552 * symbols.c (copy_symbol_attributes): New function. Copies BFD
2553 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
2554 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
2555 zero. Don't call obj_frob_forward_symbol.
2556 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
2557 X_add_number is zero.
2558 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
2560 * config/tc-i960.c: Lots of whitespace, comment reformatting,
2562 (strchr): Don't declare.
2563 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
2564 md_estimate_size_before_relax, md_ri_to_chars,
2565 md_create_short_jump, md_create_long_jump.
2566 (brtab_emit): Use data_section, not SEG_DATA.
2568 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2570 * config/vms-conf.h: new file, manually derived from conf.in.
2571 * config-gas.com: use it, and eliminate obsolete "host.h".

2575 * config/tc-ppc.c (ppc_current_block): New static variable.
2576 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to

2580 (ppc_es): Clear ppc_current_block.
2581 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
2582 from the csect of the enclosing block.
2584 * config/tc-mips.c (insns_since_cache_access): Remove.
2585 (append_insn): Remove setting of insns_since_cache_access, and
2586 special 4600 handling; it turns out not to be required.
2588 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2590 * config/tc-mips.c (md_shortopts): Remove E.
2591 (md_longopts): Add EB and EL.
2592 (md_parse_option): Handle -EB and -EL as separate options, rather
2593 than as a single -E option with an argument.

2602 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
2604 * configure.in: Test for remove, not delete. Fix cross-assembler
2606 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
2609 * read.c (pseudo_set, case O_symbol): If
2610 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
2611 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
2612 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
2614 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
2616 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
2617 many others): new macros; values obtained from "DSTRECRDS.SDL".
2618 * config/obj-vms.h (various): use them.
2619 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
2620 representation (only enum bitfields can avoid being bitstrings).
2621 (bitfield_suffix, setup_basic_type): new routines.
2622 (VMS_typedef_parse): use them. Now recognize bitfields of all
2623 integral types, not just type `int'. Caveat: the representation
2624 used for bitfields still does not work for objects placed in
2625 registers, and gcc's optimizer sometimes puts small structs there.
2627 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2629 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
2630 bit from const_flag.
2631 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
2632 (tc_frob_label): define this to call vms_check_for_special_label,
2633 and declare the latter.
2634 * config/obj-vms.c (vax_g_doubles): declare this file-scope
2636 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
2637 (vms_check_for_special_label): new routine (tc_frob_label).
2638 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
2639 and `gcc2_compiled.' labels; they won't reach here any more.
2640 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
2641 double', use `vax_g_doubles' flag to select type of double.
2642 (VMS_write_object_file) [traceback setup]: don't pass symbols
2643 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
2644 and TBT_Routine_End functions.

2648 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
2649 S_GET_VALUE() to avoid many repeated function calls.
2650 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
2651 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
2652 gets requested. [All the HACK_DEC_C_STARTUP code appears to
2653 be obsolete; gcc does it automatically for vms target. It's
2654 also misnamed, because it is for the "VAX C" run-time library,
2655 not the newer "DEC C" one which has much different startup code.]
2656 {various}: use `S_SET_xxx(symbol,new_value)' rather than
2657 `S_GET_xxx(symbol) = new_value'.
2659 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2661 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
2662 not &bfd_abs_section.
2664 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2666 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
2668 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
2670 * expr.c (expr): Don't reduce the difference of two symbols in the
2671 same frag if the symbols are not in normal sections.
2673 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
2674 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
2675 (obj_attach_unwind_info): Do not define. Not needed anymore.
2676 * config/tc-hppa.c: Delete whitespace at EOL.
2677 (struct hppa_fix_struct): Delete fx_unwind field and all references.
2678 (fix_new_hppa): Last arg is now a pointer to an int. Do not
2679 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
2680 fixups, store 32bits of unwind information in the fx_addnumber
2682 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
2683 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
2684 pointer to 32 bits of unwind info.
2685 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
2686 pointer to the dummy symbol; set the addend field to fx_addnumber.
2687 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
2688 rather than &bfd_XXX_section.
2690 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2692 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
2693 value by one; discard adjustments previously being made. From
2696 VMS- and Vax-related changes from Pat Rankin:
2697 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
2698 * vmsconf.sh: no longer have make-gas.com echo text about needing
2699 to modify the gcc-vms driver when intending to use with gcc 1.x.
2700 * as.c (parse_options): suppress 'v' from std_short_options and
2701 eliminate VMS-specific conditional initialization;
2702 [default case]: check for '-v' if md_parse_options doesn't recognize
2704 [default case, #if VMS]: check for filename argument when '-v' seen;
2706 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
2707 for O_big literal operands (double floats and long long ints);
2708 [VMS, md_shortopts]: add second colon after 'v';
2709 (md_parse_options) [VMS, case 'v']: check for argument, so
2710 caller can handle `-v' w/o arg.

2714 * config/obj-coff.c (do_relocs_for): If TC_KEEP_FX_OFFSET
2715 is defined, put the tx_offset into the r_offset.

2755 Rewrite handling of program_transform_name.
2757 * configure.in: Test for functions unlink and delete.

2763 * .gdbinit: Deleted.
2764 * aclocal.m4 (GAS_GDBINIT): Deleted.

2768 to ensure that older versions of autoconf aren't used.
2769 * Makefile.in: Added @configure_input@ line.
2770 (configure): Deleted rule.

2774 * config/obj-coff.c (fixup_segment): After handling the difference
2775 of two symbols from the same segment, set fx_subsy to NULL, to

2820 fixup is not local, to prevent relocations against externals from
2822 (md_assemble): Initialize disp_reloc field to NO_RELOC. Pass
2823 disp_reloc field to reloc() function, and use TC_RELOC to generate

3781 * config/tc-alpha.c (machine): New variable.
3782 (load_insn): New macro.
3783 (load_insn_table): New function.
3784 (md_begin): Call load_insn_table, once for basic instructions and
3785 once for appropriate PAL instruction table.

3834 VMS debugger now recognizes `long long' variables correctly.
3835 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
3836 for gcc2's predefined types "long double" (same as double, as
3837 per gcc's current state), "long long int", "long long unsigned
3838 int", and final `otherwise' case (to avoid uninitialized type
3839 and size fields). [caveat: predefined types "complex int",
3840 "complex float", "complex double", and "complex long double" are
3843 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
3844 of 0, because the latter indicates success rather than failure

4083 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
4084 R_DIR16, and R_DIR32 relocs.

4203 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
4205 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
4207 * vmsconf.sh: In generated file, get ".obj" suffix right, build
4208 source files from other directories into objects in the current
4209 directory, and specify PSECT attributes explicitly to linker.
4210 Also added missing label.
4211 * Makefile.in (stamp-mk.com): Reference new variable

4243 * subsegs.c (subsegs_begin): Call memset with args in the correct
4245 (subseg_get): Clear newly allocated seginfo, set its pointer slots
4246 to NULL instead of 0.

4275 (hppa_tc_symbol): Likewise.
4277 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
4278 elf_tc_make_sections stuff. It was there to support PA braindamage
4279 which has been fixed, and in the case of elf_tc_make_sections is
4280 redundant with elf_tc_final_processing.

4300 don't spew remainder of input file in error message.
4301 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
4302 message with reloc type and try to process remainder of file.

4314 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
4315 flag rather than signedp field. Only permit extended range if
4316 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
4317 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
4319 * config/tc-ppc.c (ppc_size): New static variable.
4320 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
4321 (md_begin): If an instruction has a size specific flag set, only
4322 add it if we are assembling that size.

4326 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
4327 cross section PC relative relocs right for COFF and ELF.
4329 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4331 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

4354 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
4355 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
4357 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
4358 branch with an instruction that uses $at, in case the branch is
4360 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
4361 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
4362 to make it pcrel_offset.
4363 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
4364 reloc->address; another gruesome hack to get gas reloc handling to
4367 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4369 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
4372 (emit_insn): New function.
4373 (md_assemble): Call it.
4374 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
4376 (lituse_pending): New variable. Set by anything that generates a
4377 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
4378 tested by code that might want to emit a LITUSE reloc.
4379 (emit_unaligned_io): New function. Currently calls md_assemble,
4380 but it should eventually be converted to generate the insn itself
4381 and call emit_insn directly.
4382 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
4383 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
4384 emit_bis_r): Likewise.
4385 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
4386 (alpha_ip, label get_macro): Don't emit the final instruction if
4388 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
4389 unaligned memory access macros.

4393 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4395 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
4396 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
4397 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

4409 * config/tc-mips.c (enum mips_pic_level): New enum.
4410 (mips_pic): Change from int to enum mips_pic_level. Change all
4411 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
4412 (load_address): Handle EMBEDDED_PIC.
4413 (macro): Handle EMBEDDED_PIC in all PIC cases.
4414 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
4415 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
4416 -non_shared to use NO_PIC (this is how the Irix 5 assembler
4417 works). Do not permit -G with SVR4_PIC.
4418 (s_abicalls): Warn if -G was used, and force -G 0.
4419 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
4420 anything but a.out, not just for ELF. For ECOFF, don't generate a
4421 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
4423 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
4425 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4431 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4433 * Makefile.in (config-stamp): If `defs' is defined, emit a
4434 preprocessor directive to create a macro named by this value into
4435 config.new; don't explicitly go for BFD_ASSEMBLER.
4436 * configure.in: Define `defs', not `BFDDEF'. Set it to
4437 MANY_SEGMENTS for any obj-coffbfd target.
4438 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
4439 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
4441 (LOCAL_LOADLIBES): Deleted.
4442 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
4443 * config/m88kcoff.mt (TDEFINES): Ditto.

4469 bfd_set_symtab is called.
4470 (dump_section_relocs): Note whether a symbol is a section symbol
4472 (adjust_reloc_syms): For now, always supply an absolute symbol for
4473 fixups without symbols but not yet `done'. Use section_symbol to
4474 get the symbol, instead of going directly for abs_symbol.
4475 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
4476 reloc is not a section symbol and is not in the symbol table.
4477 (set_symtab): New function, broken out from write_object_file.
4478 Counts symbol table instead of relying on an earlier count.
4479 (write_object_file): Call set_symtab, but do it after potentially
4480 invoking the *_frob_file macros. Don't bother counting symbols.
4481 Call symbol_remove, instead of expanding it in place. Moved the
4482 conditionalized `object_file_size' declaration down to
4483 conditionalized block where it's used. When using the absolute
4484 symbol for a fixup without a symbol, set sy_used_in_reloc.
4485 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
4486 the correct symbol for the absolute section.
4488 * subsegs.c (section_symbol): Use symbol_new instead of
4489 symbol_make, since we may want it to go into the symbol table.
4490 Make the new symbol have internal linkage. If
4491 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
4492 symbol with the newly created GAS symbol.
4493 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
4494 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

4499 (in_signed_range): New function.
4501 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
4502 (sparc_ip, label "immediate"): Reject constants for pcrel
4503 instructions only if the relocation type indicates a "call"
4504 instruction and the offset is within range of a "jmpl %g0". If
4505 it's not in range, use the absolute section symbol plus an offset.
4506 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
4508 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
4510 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
4513 * configure.in: Eliminated all targets using obj-coff but not
4514 defining BFD_ASSEMBLER; I think all such targets that are
4515 supported will be matched by real CPU-OS combinations earlier in
4517 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
4518 some comments about the dpx2 configuration, but left it disabled,
4519 since it couldn't be reached before.
4520 (target a29k-amd-ebmonold): Deleted.
4522 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4530 the 'j' operand if there are no further alternatives for this
4533 * config/obj-coffbfd.c (adjust_stab_section): Initialize
4534 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
4535 is not SEG_UNKNOWN rather than checking whether it is >= 0.
4537 * config/tc-mips.c (mips_align): Take new argument, label, and use
4538 it instead of global insn_label.
4539 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
4540 call to mips_emit_delay and pass it to mips_align.
4542 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4544 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
4546 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
4547 argument to a .callinfo directive. Don't loop forever on errors.
4549 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
4550 use pre-defined registers as arguments.

4555 S_IS_EXTERNAL when deciding whether to discard a symbol.
4557 * config-gas.com: Scan Makefile.in, not version.c, for current
4558 version number. Delete all versions of temp files when finished
4559 with them. Create config.h.
4561 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
4562 values to reduce number of lookups with S_GET_VALUE. Skip debug
4563 symbols to avoid "a really nasty bug". (From Holger Teutsch,
4564 holger@botbso.rhein-main.de.)
4565 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
4566 field. (Also from Holger Teutsch.) Watch for a would-be register
4567 mask that spans frags.
4569 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
4570 this_base, not line_base. (Patch from Andreas Arens,
4571 ari@obelix.av.rwth-aachen.de.)
4573 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
4574 look local if they're exported or undefined. Used to be done for
4577 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
4578 Get it from the looked-up symbol, instead of using the string from
4579 the input stream, which is no longer null-terminated.
4580 (LEX_PCT): New macro, defaults to 0.
4581 (lex_type): Use it for `%'.
4583 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
4584 (vip_op): Now static, and returns void. Callers changed. Added

4633 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
4634 0xffff for 'j' to be compatible with MIPS assembler. These
4635 numbers are actually treated as negative.

4646 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this
4647 work. It still doesn't. It now fails to compile, instead of
4648 silently compiling to do nothing.
4649 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define only if
4651 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

6590 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
6591 the table, require that the one without bit 0x1000000 set come
6592 first. Require further that it be case 'b' or 'P'. The a29k
6593 opcode table already meets these constraints.
6594 (machine_ip): When handling case 'i' or 'A', make sure that the

6650 * write.c (write_relocs): For relocs that are pc_relative and
6651 pcrel_offset and not partial_inplace, adjust reloc->addend to

6702 OPTIONAL_REGISTER_PREFIX if either is already defined.
6704 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
6706 * configure.in: Set bfd_gas for all sparc targets. Added facility
6707 for keeping or rejecting configurations still under development;
6708 default is to assume production environment, and reject configs
6709 still being worked on. Mark Elf configurations (except sparc and
6710 i386) as developmental. Deleted cases matching some generic names
6711 in favor of more specific names. (E.g., when we get Alpha

6729 for functions only used within tc-hppa.c, likewise for structures,
6730 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
6731 conditional code in a few small places.
6733 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
6734 structures, global variables, forward declarations together.

6736 conditional code -- try to group conditional code together
6737 into a few places. Make all functions and variables which
6738 are only used within tc-hppa.c static. PARAMize all functions.
6739 Add comments to functions. Delete unused functions, variables,
6740 #defines, etc. Delete unused members within structures. Delete
6741 ldil;ble hacks -- it is believed they were installed to work
6742 around old gas bugs. Avoid using mixed case for local
6743 functions, variables, and structures. Fix formatting problems
6744 not found by GNU-indent. Add FIXME notices for things which
6745 should be worked on the near future. Delete lots of old
6746 useless (1.36 PA-SOM) code.

6775 a multiple of the section alignment rather than always a
6778 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
6779 bits are zero (eg they specify no relocations), then do not even
6780 bother adding their entries to thesymextn section.

6824 of text, data and bss sections to 4.
6825 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
6827 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
6828 ELF, since the ELF object format does not have these type of
6829 relocations. Change the abort into as as_bad and return
6830 BFD_RELOC_NONE to silence compiler warnings.
6831 (md_assemble): Keep track of the instruction size. Allow white
6832 space between the $ and the constant for compatibility with older
6833 gases and other assemblers.

7909 type and to delay the computation of the expression until the
7910 value is actually needed. This permits setting symbols to values

9266 avoid some redefinition complaints on some systems.

9277 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

9284 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
9286 * Makefile.in: add dvi target; as-$(config).texinfo might live in

9317 dropping a space immediately following an identifier.

9319 lines; I don't think that can be done portably.
9320 * config/tc-mips.c (macro): Use $AT if target register is zero in

9347 to be on a single line.
9349 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
9351 * Makefile.in (config.h): Create file, writing out definitions of

9353 (ALL_CFLAGS): No longer define TARGET_CPU.
9355 * Makefile.in (check): Print a message, instead of quitting
9358 * as.c (main): Don't catch any signals, for now.
9360 * version.c: Deleted.

9363 (VERSION): New variable.
9364 * as.c: Include config.h.
9365 (main): Reformatted version string. Include target alias. Don't
9366 print if not requested (i.e., unknown -v argument).

9395 prototypes for all static functions. Moved existing minimal
9396 debugging format support info #ifndef OBJ_ECOFF blocks.

9445 * make-gas.com: Find obstack.obj if it's not in the current
9447 * read.c (s_ignore): Don't declare is_end_of_line. It's
9448 redundant, and triggers a VMS gcc compiler bug.
9450 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
9451 current segment as an argument. (Ignored in all cases but VMS.)
9452 All callers and definitions changed.

9476 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
9479 * configure.in: mips-bsd configuration was missing format spec.
9482 * Makefile.in (Makefile): Depends on configure.in.
9484 * config/tc-mips.c (append_insn): Don't check for alignment of
9485 frag in memory; alignment of instructions in section is a separate

9505 * config/tc-sparc.c (s_xword): Now call big_cons, so large
9506 constants are accepted, but symbolic values are not. GCC will not
9507 generate the latter currently.
9509 * frags.c (frag_init): New function.
9510 (zero_address_frag, bss_address_frag): Now initialized at run
9512 * as.c (main): Call frag_init.

9783 (operand): Treat zero byte as end-of-operand.
9785 * configure.in (per-target): Look for with_bfd_assembler option.
9786 For now, only accept "no", until the merge is done.
9788 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
9789 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
9790 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
9791 * read.c: Finish conversion to S_* macros in the VMS only
9792 parts of the program. Add "const" modifier to hex_value.
9793 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
9795 * expr.c: Add "const" modifier to hex_value.
9796 * symbols.c: Finish conversion to S_* macros in the VMS only
9797 parts of the program. Add "const" modifier to
9798 md_[long,short]_jump_size. Remove declaration of const_flag
9799 (which will be declared in obj-vms.h).
9800 * write.c: Add "const" modifier to md_[long,short]_jump_size.
9801 Fix arguments to VMS_write_object_file.
9802 * config-gas.com: New file. Script for VMS systems to set up the
9803 configuration to build gas for VMS, and create config.status.
9804 * make-gas.com: Redone to work with new scheme.

9810 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
9811 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
9812 types of malformed stabs. Change parsing algorithm so that we are
9813 more certain of having all of the information that we need on hand.
9814 * obj-vms.c (final_forward_reference): New function, used to help
9815 resolve the data types of as many struct elements as possible
9816 when some part of the struct is not fully defined by the compiler.
9817 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
9819 * obj-vms.c (VMS_write_object_file): Define all vtable psects
9820 as symbols as well in the object file. Look for external functions
9821 that start with "__vt.", and turn them into variables, since the
9822 g++ compiler is incapable of doing this.
9823 * tc-vax.c: Add '1' option for backward compatibility with older GCC
9825 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
9826 * input-scrub.c (as_where): Fix bug where as would crash if we did not
9827 have the name of the source file yet.

9833 SEG_DATA or SEG_E1 if needed.
9834 (s_lcomm): Likewise with bss_section.
9835 (s_fill): Use memset, not bzero.
9837 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

9873 declare with format attribute for -Wformat checking.
9875 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
9877 * app.c, config/tc-*.c: Don't include read.h, since it is already
9880 * These are based on patches from Minh Tran-le
9881 <mtranle@paris.intellicorp.com>.
9882 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
9883 obj_format coffbfd and gas_target i386coff for target.
9884 (i[34]86-*-isc*): New host (uses sysv).
9885 * config/i386aix.mt: Removed (no longer used).
9886 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
9888 (LDFLAGS): Added, defined as -shlib.
9889 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
9890 * config/te-sco386.h (LOCAL_LABEL): Don't define.

9905 (size_section): Restored sanity check.
9906 (do_relocs_for): Base section address on s_paddr rather than
9907 computing it. Adjust a29k R_IHIHALF special case to account for
9908 section paddr (used to require paddr to be zero). If there are no
9909 reclos, set s_relptr to 0. Set relocation size in object_headers.
9910 (fill_section): Always set s_vaddr here, removing
9911 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set

9920 set s_vaddr here. If string_byte_count remains 4, set it back to
9921 0, and only write strings out if there are some. Call
9922 fill_section before do_relocs_for and do_linenos_for.
9923 (obj_coff_section): Handle optional quoted second argument giving
9924 section characteristics.
9925 (obj_coff_bss): Added to handle .bss.

9947 (symbol_chars): Now const.
9949 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
9950 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
9952 * config/obj-coff.h: Don't use #elif.
9954 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
9955 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
9957 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

9981 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
9982 using ZERO_BASED_SEGMENTS.
9983 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
9984 never set segment address for SEG_E2 (.bss) and don't write out
9985 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
9986 (obj_coff_endef): Don't merge labels or symbols awaiting forward
9987 definitions, and don't merge tags with non-tags. Check for .bf
9988 rather than just checking whether the second character is b and
9989 the third character is f.
9990 (obj_coff_val): gcc can generate values which we don't handle
9991 correctly; discard information for now, since it only affects the
9992 debugging information.

9994 (yank_symbols): Don't merge labels.
9995 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

10287 * listing.c (debugging_pseudo): Add stabs and stabn as things to
10290 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
10292 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
10293 sections starting from zero, rather than making them consecutive.
10294 This makes subsequent reloc calculations easier, esp if the object
10295 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
10296 allocate lcomm in .data rather than in .bss. It seems that some
10297 tools can't cope with a non-zero sized bss before linkage.

10301 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10302 throughout. That enum no longer means what we thought it meant.
10304 * tc-m68k.c (md_assemble, md_parse_option): Handle new
10305 "-mno-688[58]1" options.

10323 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10325 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10326 .word is < -32768 or > 32767. The -J flag causes the error to be
10327 ignored. This is to catch over-sized switches generated by gcc on
10328 systems which don't support the broken .word hack.
10329 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10330 write.c (fixup_segment): check for signed .word overflow if
10331 WARN_SIGNED_OVERFLOW_WORD.

10372 (fill_section) added rs_machine_dependent case
10373 (write_object_file) call fixup_mdeps
10374 (fixup_segment) set fx_subsy to 0.
10375 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
10377 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
10380 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

10409 * config/tc-m68k.c (init_table): Now const. Always include 68851
10410 data, so that "bc" is available to 68040 cache instructions.
10411 Added "tt0", "tt1", and 68ec030 variants.
10412 (md_assemble): Complain if 68000 (only) and 68881 are specified.

10437 so that we can assemble hand-written libgcc code.
10439 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10441 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
10442 has already been formatted (but may still contain %-characters).
10443 (as_bad): Likewise.
10445 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
10447 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
10448 written with indirection on the last two operands, which can be
10449 either data or address registers. Added a new operand type 'r'
10450 which accepts either register type. Added '(' to notend stuff in
10451 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

10766 * write.{c,h} (fix_new): Make these declarations consistent.
10768 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
10770 * Makefile.in (strerror.o): Add rule so that broken Sun make can
10773 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
10775 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
10777 * expr.c (operand): if can't work out what sort of operand it is,
10778 then look through FLT_CHARS for a hint.
10780 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
10782 * Makefile.in, configure.in: removed traces of namesubdir,
10783 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10784 copyrights to '92, changed some from Cygnus to FSF.
10786 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
10787 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10788 copyrights to '92, changed some from Cygnus to FSF.
10790 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10792 * expr.c: If an expression is single comma, then return with
10793 SEG_ABSENT rather than an error - since the sparc front end does
10794 really strange things with things like fbge,a
10796 * as.h: include bfd.h if using many sections
10797 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
10798 local labels didn't work.
10799 * listing.c (list_symbol_table): don't core dump when there's no
10801 * write.c, write.h: call fix_new with the right number of args on
10803 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
10806 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10808 * app.c: MRI compatibility - allow single quote to start a string.
10809 * as.c: fix typo recently introduced.
10810 * as.h : Don't include aout/reloc.h - it's not right for COFF!
10811 * expr.c: Much rewriting, to accomodate MRI syntax for
10812 expressions. Also easier to read now.
10813 * listing.c: Put back defuns
10814 * read.c: modified to accept MRI syntax, put back listing pseudo
10815 ops so that an assembler built with NO_LISTING ignores list ops
10817 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
10818 machine is a SPARC or a 29K.
10819 * config/obj-aout.c: added s_sect pseudo op
10820 * config/obj-coffbfd.c: lints, set the filehdr flags right and
10821 fill in the timestamp.
10822 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
10823 anymore, define all the relocs which the tc-<x> bit will use so we
10824 can translate from them to the coff types.
10825 * config/tc-a29k.c: reloc_type isn't ane enum any more
10826 * config/tc-m68k.c: Added NO_RELOC definition.
10828 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10830 * Makefile.in: put header files before C source for TAGS; remove
10831 references to non-existent syscalls.h.
10833 * read.c, write.c subsegs.c: back out the .bss changes.
10835 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
10837 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
10839 * a.out.h: removed.
10841 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
10843 * symbols.c (local_label_name): symbols now start with ^A.
10845 * read.c, subsegs.c, write.c obj-coff.c: added handling of
10846 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
10847 generate these sections. .align: will use NOP_OPCODE or 0
10848 for padding. This is just for being nice to the
10851 * expr.c (operand): changed to generate local label "\001L0"
10852 starting with a ^A so that it is recognized as a local label.
10854 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
10856 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
10857 i/o opcodes - inb, inw, outb and outw. string manipulation with
10858 att syntax - scmp, slod, smov, ssca, ssto.
10860 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
10861 to just after .file .
10863 In obj_crawl_symbol_chain() where it tries to put the external
10864 symbols apart, with the condition:
10865 (!S_IS_DEFINED(symbolP) &&
10866 !S_IS_DEBUG(symbolP) &&
10867 !SF_GET_STATICS(symbolP))
10868 it was moving too many symbols out. So I switch it back to the
10870 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
10872 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
10873 so that we don't use the F_RELFLG which make the linker complain
10874 that somebody has stripped the relocation info.
10876 Also, the AIX ld program require that the relocation table
10877 is sorted by r_vaddr like the standard ATT assembler does.
10879 [he also changed the sizeof(struct ...)'s into the coff
10880 style FOOSZ macros. I'm not sure this is right, but I can't
10881 remember why. xoxorich.]
10883 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
10885 * Makefile.in, configure.in, doc: use the doc. Build it, install
10888 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
10890 * read.c: white space and comments only.
10892 * configure.in: use the new atof-ns32.c for ns32k.
10894 * write.c: comment change only.
10896 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
10897 aren't yet integrated.
10899 * tc-i860.[hc]: blew off the dust. Something must still be done
10900 about conflicting relocation types.
10902 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
10905 * tc-i960.c, tc-sparc.c: white space and comments only.
10907 * tc-a29k.h: delete duplicate macro definition.
10909 * new file atof-ns32k.c copied from hack's last unreleased gas.
10911 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
10913 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
10916 * nearly everything. flush ChangeLog, package as gas-1.92.1.
10917 ChangeLog's prior to this are sketchy at best. I have logs.
10918 They just aren't ChangeLogs.
