442 expression-valued symbol, and calling fix_new_exp recursively.
443 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
444 undefined symbol and a constant, fold the constant into the fixup,
445 and refer to the undefined symbol directly. Then process the
446 fixup again from scratch.
447 (write_object_file): Before calling adjust_reloc_syms, make a pass
448 through the symbol list trying to resolve values.
450 * write.c (print_fixup): New routine, for debugging.

480 default definitions matching what we were doing before.
481 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
482 always use the varargs form if not using stdarg. It's safe to
483 always use vfprintf, because libiberty will provide it if the

500 (listing_newline): Check filename as well as line number when
501 deciding whether to record it.
502 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
503 false (if defined) as well as checking for reg_section.
504 (listing_listing): Iterate fetching lines while line number is too
505 low, and we haven't run off the end of the input file.
507 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
509 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

520 * symbols.c (copy_symbol_attributes): New function. Copies BFD
521 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
522 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
523 zero. Don't call obj_frob_forward_symbol.

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

549 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
550 from the csect of the enclosing block.
552 * config/tc-mips.c (insns_since_cache_access): Remove.
553 (append_insn): Remove setting of insns_since_cache_access, and
554 special 4600 handling; it turns out not to be required.
556 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
558 * config/tc-mips.c (md_shortopts): Remove E.
559 (md_longopts): Add EB and EL.
560 (md_parse_option): Handle -EB and -EL as separate options, rather

565 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
566 involving global symbols too.
568 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
570 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
572 * configure.in: Test for remove, not delete. Fix cross-assembler
574 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to

582 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
584 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
585 many others): new macros; values obtained from "DSTRECRDS.SDL".
586 * config/obj-vms.h (various): use them.
587 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
588 representation (only enum bitfields can avoid being bitstrings).
589 (bitfield_suffix, setup_basic_type): new routines.
590 (VMS_typedef_parse): use them. Now recognize bitfields of all
591 integral types, not just type `int'. Caveat: the representation
592 used for bitfields still does not work for objects placed in
593 registers, and gcc's optimizer sometimes puts small structs there.
595 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
597 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
599 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
600 (tc_frob_label): define this to call vms_check_for_special_label,
601 and declare the latter.

605 (vms_check_for_special_label): new routine (tc_frob_label).
606 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
607 and `gcc2_compiled.' labels; they won't reach here any more.
608 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
609 double', use `vax_g_doubles' flag to select type of double.
610 (VMS_write_object_file) [traceback setup]: don't pass symbols
611 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
612 and TBT_Routine_End functions.
614 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
616 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
617 S_GET_VALUE() to avoid many repeated function calls.
618 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
619 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
620 gets requested. [All the HACK_DEC_C_STARTUP code appears to
621 be obsolete; gcc does it automatically for vms target. It's
622 also misnamed, because it is for the "VAX C" run-time library,
623 not the newer "DEC C" one which has much different startup code.]
624 {various}: use `S_SET_xxx(symbol,new_value)' rather than
625 `S_GET_xxx(symbol) = new_value'.

634 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
636 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
638 * expr.c (expr): Don't reduce the difference of two symbols in the
639 same frag if the symbols are not in normal sections.
641 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
642 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
643 (obj_attach_unwind_info): Do not define. Not needed anymore.
644 * config/tc-hppa.c: Delete whitespace at EOL.
645 (struct hppa_fix_struct): Delete fx_unwind field and all references.
646 (fix_new_hppa): Last arg is now a pointer to an int. Do not
647 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
648 fixups, store 32bits of unwind information in the fx_addnumber
650 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
651 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
652 pointer to 32 bits of unwind info.
653 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
654 pointer to the dummy symbol; set the addend field to fx_addnumber.
655 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
656 rather than &bfd_XXX_section.
658 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
660 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
661 value by one; discard adjustments previously being made. From
664 VMS- and Vax-related changes from Pat Rankin:
665 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
666 * vmsconf.sh: no longer have make-gas.com echo text about needing
667 to modify the gcc-vms driver when intending to use with gcc 1.x.
668 * as.c (parse_options): suppress 'v' from std_short_options and
669 eliminate VMS-specific conditional initialization;
670 [default case]: check for '-v' if md_parse_options doesn't recognize
672 [default case, #if VMS]: check for filename argument when '-v' seen;
674 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
675 for O_big literal operands (double floats and long long ints);
676 [VMS, md_shortopts]: add second colon after 'v';
677 (md_parse_options) [VMS, case 'v']: check for argument, so
678 caller can handle `-v' w/o arg.

730 * gdbinit.in: New file, created from old .gdbinit.
732 * aclocal.m4 (GAS_GDBINIT): Deleted.
733 * configure.in: Don't use it. Instead, generate .gdbinit from
734 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
735 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
736 to ensure that older versions of autoconf aren't used.

762 PIC implementation for i386-linux, based on code from Eric
763 Youngdale and Paul Kranenburg, with some work of my own:
765 * write.c (fixup_segment): Test TC_RELOC_RTSYM_LOC_FIXUP on fixup
766 before processing same-section pcrel relocations.

873 Update for autoconf beta 1.112:
874 * aclocal.m4 (GAS_CHECK_DECL_NEEDED, GAS_WORKING_ASSERT): New
876 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
877 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
878 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
879 message to try to ease confusion about autoconf's
880 "cross-compiling" message.
881 * acconfig.h (NEED_DECLARATION_MALLOC, NEED_DECLARATION_FREE,
882 NEED_DECLARATION_ERRNO): Renamed from NEED_*_DECLARATION.

927 using autoconf @-substitutions.
929 Wed Aug 31 17:43:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
931 * atof-generic.c: Deleted alloca handling here.
933 * Makefile.in (prefix, exec_prefix): Use @-subtitutions.
935 * aclocal.m4 (AC_OUTPUT_LINKS): Deleted redefinition, since
936 autoconf 1.109 has this fixed.
937 * configure.in: Don't change quote characters around AC_MSG_ERROR
938 invocation. Don't use AC_HEADER_STDC, since it requires running a
939 program. Cache NEED_*_DECLARATION values.

1729 (control_regs): New pointer.
1730 (m68k_ip): Use control_regs instead of testing CPU every time.

2103 * config/tc-mips.c (append_insn): Permit branches to be switched
2104 with the preceding instruction even if .set nobopt has been seen.
2105 .set nobopt actually controls whether to bring up an instruction

2177 directory, and specify PSECT attributes explicitly to linker.
2178 Also added missing label.

2246 elf_tc_make_sections stuff. It was there to support PA braindamage
2247 which has been fixed, and in the case of elf_tc_make_sections is
2248 redundant with elf_tc_final_processing.

2363 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2364 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2365 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

2381 (macro): Handle EMBEDDED_PIC in all PIC cases.
2382 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2383 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2384 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2385 works). Do not permit -G with SVR4_PIC.
2386 (s_abicalls): Warn if -G was used, and force -G 0.
2387 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for

2393 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2395 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2396 parameters to avoid losing when compiling with HP CC.
2397 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2399 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2401 * Makefile.in (config-stamp): If `defs' is defined, emit a
2402 preprocessor directive to create a macro named by this value into
2403 config.new; don't explicitly go for BFD_ASSEMBLER.
2404 * configure.in: Define `defs', not `BFDDEF'. Set it to
2405 MANY_SEGMENTS for any obj-coffbfd target.
2406 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2407 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2409 (LOCAL_LOADLIBES): Deleted.
2410 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2411 * config/m88kcoff.mt (TDEFINES): Ditto.

2437 bfd_set_symtab is called.
2438 (dump_section_relocs): Note whether a symbol is a section symbol
2440 (adjust_reloc_syms): For now, always supply an absolute symbol for
2441 fixups without symbols but not yet `done'. Use section_symbol to
2442 get the symbol, instead of going directly for abs_symbol.
2443 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2444 reloc is not a section symbol and is not in the symbol table.
2445 (set_symtab): New function, broken out from write_object_file.
2446 Counts symbol table instead of relying on an earlier count.
2447 (write_object_file): Call set_symtab, but do it after potentially
2448 invoking the *_frob_file macros. Don't bother counting symbols.
2449 Call symbol_remove, instead of expanding it in place. Moved the
2450 conditionalized `object_file_size' declaration down to
2451 conditionalized block where it's used. When using the absolute
2452 symbol for a fixup without a symbol, set sy_used_in_reloc.
2453 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2454 the correct symbol for the absolute section.
2456 * subsegs.c (section_symbol): Use symbol_new instead of
2457 symbol_make, since we may want it to go into the symbol table.
2458 Make the new symbol have internal linkage. If
2459 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2460 symbol with the newly created GAS symbol.
2461 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2462 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2469 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2470 (sparc_ip, label "immediate"): Reject constants for pcrel
2471 instructions only if the relocation type indicates a "call"
2472 instruction and the offset is within range of a "jmpl %g0". If
2473 it's not in range, use the absolute section symbol plus an offset.
2474 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2476 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2478 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2481 * configure.in: Eliminated all targets using obj-coff but not
2482 defining BFD_ASSEMBLER; I think all such targets that are
2483 supported will be matched by real CPU-OS combinations earlier in
2485 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2486 some comments about the dpx2 configuration, but left it disabled,
2487 since it couldn't be reached before.
2488 (target a29k-amd-ebmonold): Deleted.

2498 the 'j' operand if there are no further alternatives for this
2501 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2502 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2503 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2505 * config/tc-mips.c (mips_align): Take new argument, label, and use
2506 it instead of global insn_label.
2507 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2508 call to mips_emit_delay and pass it to mips_align.
2510 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2512 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2514 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2515 argument to a .callinfo directive. Don't loop forever on errors.

2523 S_IS_EXTERNAL when deciding whether to discard a symbol.
2525 * config-gas.com: Scan Makefile.in, not version.c, for current
2526 version number. Delete all versions of temp files when finished
2527 with them. Create config.h.

2530 values to reduce number of lookups with S_GET_VALUE. Skip debug
2531 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2532 holger@botbso.rhein-main.de.)
2533 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2534 field. (Also from Holger Teutsch.) Watch for a would-be register
2535 mask that spans frags.
2537 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2538 this_base, not line_base. (Patch from Andreas Arens,

2542 look local if they're exported or undefined. Used to be done for
2545 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

2549 (lex_type): Use it for `%'.
2551 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

4696 through inclusion of tc-hppa.h. Delete all forward declarations
4697 for functions only used within tc-hppa.c, likewise for structures,

4706 are only used within tc-hppa.c static. PARAMize all functions.
4707 Add comments to functions. Delete unused functions, variables,
4708 #defines, etc. Delete unused members within structures. Delete
4709 ldil;ble hacks -- it is believed they were installed to work
4710 around old gas bugs. Avoid using mixed case for local
4711 functions, variables, and structures. Fix formatting problems
4712 not found by GNU-indent. Add FIXME notices for things which
4713 should be worked on the near future. Delete lots of old

7184 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
7185 a29k .bss section; the mondfe program doesn't like it.

7200 (srcdir): Delete second, bogus definition.
7201 (as.info): Look for as-*.texinfo in current directory rather than

7206 source directory, if that's not the current directory.
7208 * configure.in (per-host): Accept MIPS host with BSD version
7210 (per-target): Classify i486 as i386. Use generic cpu_type instead

7229 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
7230 process relocs if there aren't any relocs to process. Avoids
7231 malloc/free bug on SCO too.

7234 avoid some redefinition complaints on some systems.
7235 (const, volatile): Don't need these conditionally defined if we
7236 use CONST and VOLATILE from ansidecl.h.
7237 (seg_name): Use CONST, not const.
7239 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
7241 * config/tc-mips.c: Reindented to GNU standards.
7243 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
7245 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
7246 (fixup_segment): Add a29k special case; the linker is not prepared
7247 to see a segment offset here.
7249 * app.c (do_scrub_next_char): Added new state, 10, modifying state
7250 9 to only keep a space in between identifier characters.
7252 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
7254 * Makefile.in: add dvi target; as-$(config).texinfo might live in
7255 srcdir, might be in objdir.
7257 * doc/Makefile.in: dvi depends on as.dvi

7275 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
7276 bignums, but don't emit error message.
7278 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
7280 * Makefile.in (targ-cpu.o): Depend on config.h.
7282 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
7284 * app.c (do_scrub_next_char): Added new state, 9, to avoid
7285 dropping a space immediately following an identifier.
7286 * expr.c, write.c: Rewrote assert expressions to not use multiple
7287 lines; I don't think that can be done portably.
7288 * config/tc-mips.c (macro): Use $AT if target register is zero in
7289 load instruction, which it can be for a floating point load.
7291 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

7299 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
7302 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
7303 z8k-opc.h, not z8k.h.
7305 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
7308 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

7312 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)

7359 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.

7363 prototypes for all static functions. Moved existing minimal
7364 debugging format support info #ifndef OBJ_ECOFF blocks.

7366 does not support a non sign extended high 16 bits reloc. Adjusted
7367 all callers accordingly.
7368 (tc_get_register): Renamed from get_register, and made non-static.
7370 * config/mips-big.mt, config/mips-lit.mt: New files. Define

7413 * make-gas.com: Find obstack.obj if it's not in the current
7415 * read.c (s_ignore): Don't declare is_end_of_line. It's
7416 redundant, and triggers a VMS gcc compiler bug.
7418 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7419 current segment as an argument. (Ignored in all cases but VMS.)
7420 All callers and definitions changed.
7422 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
7424 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING

7436 (obj_elf_xstab): New routine.
7437 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
7438 argument to s_ignore. Put "#if 0" around unused code.
7439 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
7440 Call elf_xstabs for .stabs and .xstabs operators.
7442 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
7444 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
7447 * configure.in: mips-bsd configuration was missing format spec.
7450 * Makefile.in (Makefile): Depends on configure.in.
7452 * config/tc-mips.c (append_insn): Don't check for alignment of
7453 frag in memory; alignment of instructions in section is a separate
7456 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
7459 * listing.h: Always provide function declarations, not macros, so
7462 Tue Mar 2 00:50:43 1993 John Gilmore (gnu@cygnus.com)

7473 * config/tc-sparc.c (s_xword): Now call big_cons, so large
7474 constants are accepted, but symbolic values are not. GCC will not
7475 generate the latter currently.
7477 * frags.c (frag_init): New function.
7478 (zero_address_frag, bss_address_frag): Now initialized at run
7480 * as.c (main): Call frag_init.

7747 * expr.c (operand): If character other than comma or newline is a
7748 logical end-of-line character, use the newline case.

7750 (operand): Set X_add_number field for floating-point numbers.
7751 (operand): Treat zero byte as end-of-operand.
7753 * configure.in (per-target): Look for with_bfd_assembler option.
7754 For now, only accept "no", until the merge is done.
7756 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):

7766 md_[long,short]_jump_size. Remove declaration of const_flag
7767 (which will be declared in obj-vms.h).
7768 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7769 Fix arguments to VMS_write_object_file.
7770 * config-gas.com: New file. Script for VMS systems to set up the

7779 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7780 types of malformed stabs. Change parsing algorithm so that we are
7781 more certain of having all of the information that we need on hand.
7782 * obj-vms.c (final_forward_reference): New function, used to help
7783 resolve the data types of as many struct elements as possible

7801 SEG_DATA or SEG_E1 if needed.
7802 (s_lcomm): Likewise with bss_section.
7803 (s_fill): Use memset, not bzero.

7832 if these are used or defined, if BFD_ASSEMBLER.
7833 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7834 subseg_new split into two functions.
7835 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7837 * as.h (volatile): Don't define if already defined.
7838 (had_errors, had_warnings): Provide prototypes for ANSI C even if
7840 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,

7858 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7859 (DOT_LABEL_PREFIX): Define.

7861 name rather than L0\001.
7862 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7864 * symbols.c, symbols.h (local_bss_counter): Removed.
7865 * write.c (write_object_file): bss no longer uses

7873 (size_section): Restored sanity check.
7874 (do_relocs_for): Base section address on s_paddr rather than
7875 computing it. Adjust a29k R_IHIHALF special case to account for

7877 reclos, set s_relptr to 0. Set relocation size in object_headers.
7878 (fill_section): Always set s_vaddr here, removing
7879 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7880 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7881 Set STYP_INFO for .comment.
7882 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7883 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

7885 H_{SET,GET}_* macros.
7886 (do_linenos_for): Set lineno size in object_headers.
7887 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7888 set s_vaddr here. If string_byte_count remains 4, set it back to
7889 0, and only write strings out if there are some. Call
7890 fill_section before do_relocs_for and do_linenos_for.
7891 (obj_coff_section): Handle optional quoted second argument giving
7892 section characteristics.
7893 (obj_coff_bss): Added to handle .bss.
7894 (obj_coff_ident): Added to handle .ident (puts string in .comment

7918 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7920 * config/obj-coff.h: Don't use #elif.
7922 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7923 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
7925 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
7927 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

7937 Sun Dec 13 00:04:38 1992 Ian Lance Taylor (ian@cygnus.com)
7939 * read.c (read_a_source_file): avoid calling xmalloc (0).
7941 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
7943 * listing.c: Call xmalloc, not malloc; don't declare malloc.
7945 * Changes to support SCO 3.2v4:
7946 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
7947 SEG_BSS, fill with NOP_OPCODE.
7948 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
7949 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
7950 using ZERO_BASED_SEGMENTS.
7951 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7952 never set segment address for SEG_E2 (.bss) and don't write out
7953 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7954 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7955 definitions, and don't merge tags with non-tags. Check for .bf
7956 rather than just checking whether the second character is b and
7957 the third character is f.
7958 (obj_coff_val): gcc can generate values which we don't handle
7959 correctly; discard information for now, since it only affects the
7960 debugging information.
7961 (tag_find_or_name): Don't insert tags in the symbol table.
7962 (yank_symbols): Don't merge labels.
7963 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
7964 already defined. Fill subsegments with NOP_OPCODE, not 0. Don't
7965 set segment address if ZERO_BASED_SEGMENTS.
7966 (obj_coff_section): Accept and ignore a trailing quoted string, as
7967 used in AT&T i386 syntax.
7968 (fixup_segment): Take segment as argument. On the i386, adjust PC
7969 relative addends by the segment vaddr.
7970 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
7971 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
7972 * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

8073 xrealloc from xrealloc.c.
8074 * xrealloc.c: Deleted.
8075 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
8077 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
8080 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
8082 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;

8101 * all files: Whitespace changes for GNU indentation style, done by
8102 GNU `indent'. Some cleanup still needed, especially of comments.
8104 * configure.in: No te-386bsd.h file exists; don't try to use it.

8108 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
8109 could be doing emulation.
8111 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8114 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
8117 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
8119 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

8143 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8145 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8146 constant will not fit in an immediate field.
8147 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

8182 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8184 * Support for i386-sysv.
8185 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8204 fix i960+non-bfd coff bit rot.
8205 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
8206 support for C source listings. (obj_coff_endef): look in the right

8209 * tc-m68k.c (get_num): make it work for all segments, not just the
8212 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
8214 * configure.in: recognize i386-*-bsd emulation.

8223 * tc-z8k.c: lots of bug fixes
8225 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8227 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8228 #elif, since it is not supported by old compilers.
8229 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8230 couple of expressions in tc-m68k.c.
8232 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8234 * read.c (cons): If NO_RELOC is defined, use it.
8236 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8238 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8240 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8241 local labels to start with a .) and set REGISTER_PREFIX to %.
8242 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8244 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

8255 * listing.c (debugging_pseudo): Add stabs and stabn as things to
8258 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8260 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8261 sections starting from zero, rather than making them consecutive.
8262 This makes subsequent reloc calculations easier, esp if the object
8263 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8264 allocate lcomm in .data rather than in .bss. It seems that some
8265 tools can't cope with a non-zero sized bss before linkage.
8267 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8269 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8270 throughout. That enum no longer means what we thought it meant.

8273 "-mno-688[58]1" options.
8275 * tc-m68k.c: Added CPU32 support.

8283 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
8284 Change LIBDEPS dependence to LIBS.
8286 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
8288 * Makefile.in (install): if $(tooldir) exists, install as in
8291 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8293 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8294 .word is < -32768 or > 32767. The -J flag causes the error to be
8295 ignored. This is to catch over-sized switches generated by gcc on
8296 systems which don't support the broken .word hack.
8297 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8298 write.c (fixup_segment): check for signed .word overflow if
8299 WARN_SIGNED_OVERFLOW_WORD.
8301 * write.c (fixup_segment): fixed missing parens in expression
8302 checking for byte or word overflow.
8304 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
8305 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
8306 WARN_SIGNED_OVERFLOW_WORD.

8314 * obj-coffbfd.h : added stuff
8315 * tc-i386.c (tc_coff_fix2rtype): new function
8316 * tc-i386.h : new coff defines
8318 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8320 * input-scrub.c (input_scrub_push): call input_file_begin, not
8322 messages.c (as_perror): print ": " between the passed in error and
8323 the strerror, like perror does.
8325 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
8327 * Makefile.in: use gas_target instead of modifying target_cpu.
8328 From Steve Chamberlain:
8329 Makefile.in: Handle m68*-*-coff*.
8330 read.c, read.h: add mult argument to s_space
8332 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8333 Motorola and MIT syntax; gas can now assemble either type of
8335 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
8336 From Steve Chamberlain:
8337 m68kcoff.mt: for m68k COFF.
8338 obj-coffbfd.c: (fixup_mdeps) added

8340 (fill_section) added rs_machine_dependent case
8341 (write_object_file) call fixup_mdeps
8342 (fixup_segment) set fx_subsy to 0.
8343 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8345 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8348 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8350 * Makefile.in (LIBS): Include opcode library.
8352 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
8354 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
8355 including zero are accepted, pass +0.0.

8372 tc-i960.c (md_ri_to_chars): Always output bout object file in
8373 little endian byte order (used to use endianness of host).
8375 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8377 * config/tc-m68k.c (init_table): Now const. Always include 68851
8378 data, so that "bc" is available to 68040 cache instructions.
8379 Added "tt0", "tt1", and 68ec030 variants.
8380 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8381 (enum _register): Added TT0, TT1.
8382 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
8383 line number correctly in "internal error" messages. Don't print
8384 architecture-mismatch message for operand errors.
8386 From Colin Smith (colin@wrs.com):
8387 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
8388 than install_operand.
8390 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8392 * listing.c (buffer_line): rewind to the start of include
8393 files, they might be included twice.
8395 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
8397 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
8399 * Makefile.in: defined TARGET_CPU for C code so that it can choose
8400 one element of a family.
8402 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
8404 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
8405 so that we can assemble hand-written libgcc code.
8407 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8409 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8410 has already been formatted (but may still contain %-characters).
8413 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8415 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8416 written with indirection on the last two operands, which can be
8417 either data or address registers. Added a new operand type 'r'
8418 which accepts either register type. Added '(' to notend stuff in
8419 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
8421 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
8423 * as.h (enum _relax_state): Start off at one, not zero, to better
8424 catch uninitialized-variable errors.

8616 * write.c (write_object_file): keep the fix_tail clean, which
8617 fixes a bug in -R where relocations were being lost.
8619 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
8621 * configure.in: recognize m680x0 as having sun3 emulation mode for

8668 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8670 * Makefile.in (install): Install into $(tooldir)/bin, since that's
8671 where gcc looks for it.
8673 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
8675 * Makefile.in: Changed some lines to be less confusing for some

8745 * expr.c (operand): if can't work out what sort of operand it is,
8746 then look through FLT_CHARS for a hint.
8748 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
8750 * Makefile.in, configure.in: removed traces of namesubdir,

8752 copyrights to '92, changed some from Cygnus to FSF.
8754 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
8755 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8756 copyrights to '92, changed some from Cygnus to FSF.
8758 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8760 * expr.c: If an expression is single comma, then return with
8761 SEG_ABSENT rather than an error - since the sparc front end does
8762 really strange things with things like fbge,a
8764 * as.h: include bfd.h if using many sections
8765 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8766 local labels didn't work.
8767 * listing.c (list_symbol_table): don't core dump when there's no
8769 * write.c, write.h: call fix_new with the right number of args on
8771 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8774 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8776 * app.c: MRI compatibility - allow single quote to start a string.
8777 * as.c: fix typo recently introduced.
8778 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8779 * expr.c: Much rewriting, to accomodate MRI syntax for
8780 expressions. Also easier to read now.
8781 * listing.c: Put back defuns
8782 * read.c: modified to accept MRI syntax, put back listing pseudo
8783 ops so that an assembler built with NO_LISTING ignores list ops
8785 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8786 machine is a SPARC or a 29K.
8787 * config/obj-aout.c: added s_sect pseudo op
8788 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8789 fill in the timestamp.
8790 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8791 anymore, define all the relocs which the tc-<x> bit will use so we
8792 can translate from them to the coff types.
8793 * config/tc-a29k.c: reloc_type isn't ane enum any more
8794 * config/tc-m68k.c: Added NO_RELOC definition.
8796 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8798 * Makefile.in: put header files before C source for TAGS; remove
8799 references to non-existent syscalls.h.
8801 * read.c, write.c subsegs.c: back out the .bss changes.
8803 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8805 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8809 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8811 * symbols.c (local_label_name): symbols now start with ^A.
8813 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8814 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8815 generate these sections. .align: will use NOP_OPCODE or 0
8816 for padding. This is just for being nice to the
8819 * expr.c (operand): changed to generate local label "\001L0"
8820 starting with a ^A so that it is recognized as a local label.
8822 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8824 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8825 i/o opcodes - inb, inw, outb and outw. string manipulation with
8826 att syntax - scmp, slod, smov, ssca, ssto.
8828 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8829 to just after .file .
8831 In obj_crawl_symbol_chain() where it tries to put the external
8832 symbols apart, with the condition:
8833 (!S_IS_DEFINED(symbolP) &&
8834 !S_IS_DEBUG(symbolP) &&
8835 !SF_GET_STATICS(symbolP))
8836 it was moving too many symbols out. So I switch it back to the
8838 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8840 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8841 so that we don't use the F_RELFLG which make the linker complain
8842 that somebody has stripped the relocation info.
8844 Also, the AIX ld program require that the relocation table
8845 is sorted by r_vaddr like the standard ATT assembler does.
8847 [he also changed the sizeof(struct ...)'s into the coff
8848 style FOOSZ macros. I'm not sure this is right, but I can't
8849 remember why. xoxorich.]
8851 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

8858 * read.c: white space and comments only.
8860 * configure.in: use the new atof-ns32.c for ns32k.
8862 * write.c: comment change only.
8864 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8865 aren't yet integrated.
8867 * tc-i860.[hc]: blew off the dust. Something must still be done
8868 about conflicting relocation types.
8870 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8873 * tc-i960.c, tc-sparc.c: white space and comments only.
8875 * tc-a29k.h: delete duplicate macro definition.
8877 * new file atof-ns32k.c copied from hack's last unreleased gas.
8879 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8881 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8884 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8885 ChangeLog's prior to this are sketchy at best. I have logs.
8886 They just aren't ChangeLogs.
8893 version-control: never
