3280 * config/tc-mips.c (md_pseudo_table): If OBJ_ELF, handle .section.
3281 (s_elf_section): New static function.
3282 * ecoff.c (ecoff_build_symbols): Don't abort if we don't recognize

3287 * config/tc-hppa.c (md_apply_fix): Set new_val to 8 for all
3288 fixups to branch instructions (not just pc-relative ones) which

3318 * config/tc-hppa.c: Eliminate all uses of fx_addnumber.
3319 (tc_gen_reloc): Simplify. It's no longer necessary to set a
3320 reloc's addend field to zero for function symbols.
3321 (md_apply_fix): Simplify. For fixups which will require a SOM
3322 reloc, just clear out the necessary bits in the output file.

3326 * Makefile.in (BISON): Use bison -y, not bison.

3340 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
3342 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
3343 it's better to use the one in libiberty.
3345 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3347 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
3348 change; it breaks the rs6000 support, and doesn't seem to be
3351 Wed Oct 12 11:56:50 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
3353 * config/tc-i386.h,te-netbsd532.h (TARGET_FORMAT): Changed to

3359 rather than explicitly adding the frag address.
3360 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark

3362 used to be added by coff_add_linesym, removed Oct 7.
3363 (coff_adjust_section_syms): Ignore sections with no seginfo.
3365 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3367 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a
3368 "stage" symlink to the appropriate stage* directory, and use it
3369 instead in the -B options.
3370 (comparison): Revert yesterday's change.
3372 Tue Oct 11 16:48:11 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3374 * config/tc-sparc.c (tc_gen_reloc): For non-a.out relocations, if

3377 Tue Oct 11 15:24:00 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
3379 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
3380 for an embedded PIC switch expression, since the definition of
3381 S_IS_LOCAL was changed.
3383 Tue Oct 11 15:05:11 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
3385 * Makefile.in (comparison): When comparing as.new or gasp.new, try
3386 running the binary through sed to avoid differences due to
3387 "stage1" or "stage2" having been written into the binary.
3389 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
3391 ELF symbol size handling, based on code from Eric Youngdale:
3392 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an
3393 expression pointer to the symbol structure, used for `size'
3394 expressions that couldn't be reduced to constants when initially
3396 (elf_frob_symbol): Declare.

3399 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
3401 (obj_elf_size): Deleted unused code. If size is non-reducible
3402 expression, allocate some storage for the sy_obj field and copy
3404 (elf_frob_symbol): New function. Computes sizes, calls
3405 ecoff_frob_symbol if appropriate.
3407 * write.c (fixup_segment): For i386 elf and coff (for now), don't
3408 add in value of symbol from another defined section of the file.
3410 Fri Oct 7 17:54:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

3454 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
3456 (diststuff): New target; builds DISTSTUFF.
3457 (realclean): Separate target, depend on clean and distclean, then
3459 * make-gas.com: Deleted.

3462 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
3464 (i386_operand): Don't look up section symbol for
3466 (reloc): Always permit return of 8- and 16-bit relocation types.
3467 Add a space after "pc-relative" in the error message.
3468 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
3469 BFD_RELOC_386_GOTOFF relocs.

3473 (TC_VALIDATE_FIX): New macro -- call it.
3474 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.

3477 it rather than stdarg.h.
3479 * write.h (struct fix): Added new bitfield fx_plt, for fixups
3480 referring to PLT entries.
3481 * write.c (fix_new_internal): Initialize fx_plt to zero.
3482 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
3483 Don't adjust fx_offset by frag address, since S_GET_VALUE now
3484 includes the frag address.
3485 (fixup_segment): Changed local var PCREL to type int, added PLT.
3486 If PC-relative fixup refers to a PLT entry for a symbol in the
3487 current section, don't reduce it.

3493 and after processing.
3494 (print_fixup): Added prototype. Show address on first line. Show
3495 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if

3509 Show fx_r_type and fx_addsy fields.
3511 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3513 * configure.in: Set bfd_gas for all sparc targets in one place,
3514 instead of separately for each. Correctly handle user-supplied
3515 "--enable-bfd-gas" option.
3517 * gdbinit.in: Move "break abort" to end, in case gdb complains.
3519 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
3522 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
3523 processing if add_symbol is undefined or in expr_section.
3524 (resolve_symbol_value, case O_add): For symbol plus
3525 constant-valued symbol, convert to O_symbol and re-reduce.
3526 (S_GET_VALUE): If symbol needs resolving, resolve it.
3527 (indent_level): No longer static.
3528 (print_symbol_value_1): Don't print frag address if it matches
3529 zero_address_frag. Don't print "resolving" if already resolved.

3532 (print_expr_1): Fix whitespace before printing X_add_number.
3534 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
3535 not symbol_new, for symbols holding expression values.
3536 * expr.h (make_expr_symbol): Move declaration here.
3537 * write.c (fix_new_exp): Handle O_add by creating an
3538 expression-valued symbol, and calling fix_new_exp recursively.
3539 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
3540 undefined symbol and a constant, fold the constant into the fixup,
3541 and refer to the undefined symbol directly. Then process the
3542 fixup again from scratch.
3543 (write_object_file): Before calling adjust_reloc_syms, make a pass
3544 through the symbol list trying to resolve values.
3546 * write.c (print_fixup): New routine, for debugging.
3547 (write_relocs): Call bfd_install_relocation. Deleted various
3548 hacks for working around problems with bfd_perform_relocation.
3550 * Makefile.in (VERSION): Update to 2.4.90.
3552 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3554 * Makefile.in (gasp.o): Depends upon config.h.
3556 * config/tc-mips.c: Include subsegs.h.
3557 (md_apply_fix): If an unconditional b or bal overflows, and we are
3558 not assembling PIC code, replace it with a j or jal.
3560 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
3561 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
3563 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3565 * write.c (write_relocs): Add file name and line number to
3566 as_fatal calls. Handle bfd_reloc_overflow case specifically when
3567 RELOC_EXPANSION_POSSIBLE.
3569 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3571 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
3572 here. Use them for deciding which PRINTF*LIKE macro definitions
3574 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
3575 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
3576 default definitions matching what we were doing before.
3577 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
3578 always use the varargs form if not using stdarg. It's safe to
3579 always use vfprintf, because libiberty will provide it if the
3580 native system doesn't. Also, always make format be const.
3581 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
3583 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

3596 (listing_newline): Check filename as well as line number when
3597 deciding whether to record it.
3598 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
3599 false (if defined) as well as checking for reg_section.
3600 (listing_listing): Iterate fetching lines while line number is too
3601 low, and we haven't run off the end of the input file.
3603 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
3605 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
3607 * ecoff.c (ecoff_generate_asm_lineno): check if
3608 current_stabs_filename is NULL before strcmp.
3609 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
3612 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3614 * config/ho-*.h: Now-unused files deleted.
3616 * symbols.c (copy_symbol_attributes): New function. Copies BFD
3617 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
3618 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
3619 zero. Don't call obj_frob_forward_symbol.
3620 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
3621 X_add_number is zero.
3622 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
3624 * config/tc-i960.c: Lots of whitespace, comment reformatting,
3626 (strchr): Don't declare.
3627 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
3628 md_estimate_size_before_relax, md_ri_to_chars,
3629 md_create_short_jump, md_create_long_jump.
3630 (brtab_emit): Use data_section, not SEG_DATA.
3632 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3634 * config/vms-conf.h: new file, manually derived from conf.in.
3635 * config-gas.com: use it, and eliminate obsolete "host.h".
3637 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3639 * config/tc-ppc.c (ppc_current_block): New static variable.
3640 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
3641 ppc_current_block. Don't move around any stab symbol, just those
3643 (ppc_bs): Set ppc_current_block.
3644 (ppc_es): Clear ppc_current_block.
3645 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
3646 from the csect of the enclosing block.
3648 * config/tc-mips.c (insns_since_cache_access): Remove.
3649 (append_insn): Remove setting of insns_since_cache_access, and
3650 special 4600 handling; it turns out not to be required.
3652 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3654 * config/tc-mips.c (md_shortopts): Remove E.
3655 (md_longopts): Add EB and EL.
3656 (md_parse_option): Handle -EB and -EL as separate options, rather
3657 than as a single -E option with an argument.
3659 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
3661 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
3662 involving global symbols too.
3664 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3666 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
3668 * configure.in: Test for remove, not delete. Fix cross-assembler
3670 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
3673 * read.c (pseudo_set, case O_symbol): If
3674 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
3675 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
3676 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
3678 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
3680 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
3681 many others): new macros; values obtained from "DSTRECRDS.SDL".
3682 * config/obj-vms.h (various): use them.
3683 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
3684 representation (only enum bitfields can avoid being bitstrings).
3685 (bitfield_suffix, setup_basic_type): new routines.
3686 (VMS_typedef_parse): use them. Now recognize bitfields of all
3687 integral types, not just type `int'. Caveat: the representation
3688 used for bitfields still does not work for objects placed in
3689 registers, and gcc's optimizer sometimes puts small structs there.
3691 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3693 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
3694 bit from const_flag.
3695 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
3696 (tc_frob_label): define this to call vms_check_for_special_label,
3697 and declare the latter.
3698 * config/obj-vms.c (vax_g_doubles): declare this file-scope
3700 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
3701 (vms_check_for_special_label): new routine (tc_frob_label).
3702 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
3703 and `gcc2_compiled.' labels; they won't reach here any more.
3704 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
3705 double', use `vax_g_doubles' flag to select type of double.
3706 (VMS_write_object_file) [traceback setup]: don't pass symbols
3707 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
3708 and TBT_Routine_End functions.
3710 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
3712 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
3713 S_GET_VALUE() to avoid many repeated function calls.
3714 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
3715 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
3716 gets requested. [All the HACK_DEC_C_STARTUP code appears to
3717 be obsolete; gcc does it automatically for vms target. It's
3718 also misnamed, because it is for the "VAX C" run-time library,
3719 not the newer "DEC C" one which has much different startup code.]
3720 {various}: use `S_SET_xxx(symbol,new_value)' rather than
3721 `S_GET_xxx(symbol) = new_value'.

4724 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
4725 to put a common symbol in a set.

4770 * read.c (emit_expr): Use memset to zero out memory, rather than
4771 going through md_number_to_chars. This permits handling symbolic

4824 m68040_control_regs, m68060_control_regs): New arrays.
4825 (control_regs): New pointer.
4826 (m68k_ip): Use control_regs instead of testing CPU every time.
4827 Use last_movec_reg too. In error messages, handle 68060, and
4828 print 68060 for mfloat, too.
4829 (m68k_init_after_args): Handle "68060". Use m68040up for making
4830 m68851 choice. Set control_regs.

5118 * listing.c (list_symbol_table): Print "NO DEFINED SYMBOLS" and
5119 "NO UNDEFINED SYMBOLS" if there aren't any, instead of displaying
5120 the header with an empty list.
5122 * config/obj-coffbfd.c (fill_section): Check COFF_NOLOAD_PROBLEM
5123 also before setting STYP_NOLOAD for .bss section.
5125 * config/tc-m68k.c (flag_reg_prefix_optional): New variable.
5126 Initialized to value of REGISTER_PREFIX_OPTIONAL, if defined, or
5128 (m68k_reg_parse): If flag_reg_prefix_optional is set, permit
5129 register prefix to be absent.
5130 (m68k_ip_op): Accept `&' also for immediate constants.
5131 (insert_reg): Don't bother with (two!?) sanity checks of the
5132 symbol table when inserting each register.

5134 flag_reg_prefix_optional if "register-prefix-optional" is passed.
5135 * config/tc-m68k.h (REGISTER_PREFIX): Always define if not already
5137 (OPTIONAL_REGISTER_PREFIX): Don't define.
5138 (REGISTER_PREFIX_OPTIONAL): If not already defined, define as zero
5139 or one depending on M68KCOFF.

5142 * config/tc-m68k.c (DATA, ADDR, SP, FPREG, COPNUM, BAD, BAC):
5143 Define as macros instead of enumerators, since the Apollo compiler
5144 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum
5146 (make_pcrel_absolute) [NO_PCREL_RELOCS]: New function.
5147 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
5148 R_DIR16, and R_DIR32 relocs.
5149 * config/tc-m68k.h [TE_APOLLO] (COFF_MAGIC, COFF_AOUTHDR_MAGIC):
5150 Use Apollo versions.
5151 [TE_APOLLO] (OBJ_COFF_OMIT_OPTIONAL_HEADER): Undefine. That is,

5153 (COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
5155 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
5156 can be used within a label name.
5158 * config/tc-m68k.h (m68k_init_after_args): Declare.
5159 (tc_init_after_args): Define as m68k_init_after_args.
5160 * config/tc-m68k.c (m68k_init_after_args): New function,
5161 containing one-shot code from md_assemble. Added warning for
5162 combination of 68040 and 68851.

5177 and bfd_ecoff_set_regmasks to set the GP value and the register
5178 masks, rather than using the now obsolete fake .reginfo section.
5180 Fri Apr 22 15:17:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5182 * listing.c (list_symbol_table): Don't print register symbols as
5185 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
5186 underscores, since symbol_new will already have done it.
5187 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
5189 * as.c (main): If tc_init_after_args is defined, invoke it after
5190 all arguments have been processed.
5192 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
5193 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
5194 section instead of .text. Call create_target_segments.
5195 * read.c (demand_copy_string): No longer static.
5197 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5199 * config/tc-mips.c (append_insn): Permit branches to be switched
5200 with the preceding instruction even if .set nobopt has been seen.
5201 .set nobopt actually controls whether to bring up an instruction
5202 from the branch target, which gas does not currently support.
5204 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5206 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only
5207 when BFD_ASSEMBLER is not defined, and all conditionals relating

5219 * config/tc-sparc.c (md_section_align): Always round up to
5220 multiple of alignment power specified in bfd target vector.
5222 * gasp.c: Include ctype.h.

5243 * config/tc-hppa.c (pa_parse_space_stmt): Use the built-in
5244 defaults for defined, private, and spnum fields for the

5246 not reset the segment if just updating a space.
5247 (pa_spaces_begin): Set BFD section flags for all built-in
5250 Fri Apr 15 10:51:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

5253 (add_procedure): Set first_proc_ptr if it hasn't been set.
5254 (ecoff_build_lineno): If the first procedure does not start at
5255 address zero, insert a dummy line to compensate.
5257 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
5260 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5262 * expr.c (operand): Try to parse "0f" and "0b" sequences as
5263 floating point and binary numbers respectively; if it doesn't
5264 work, treat them as local labels.
5266 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
5267 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
5269 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
5271 * vmsconf.sh: In generated file, get ".obj" suffix right, build
5272 source files from other directories into objects in the current
5273 directory, and specify PSECT attributes explicitly to linker.
5274 Also added missing label.
5275 * Makefile.in (stamp-mk.com): Reference new variable
5276 VMS_OTHER_OBJS for list of non-local object files, instead of

5293 argument, the reloc type.
5294 (load_register): Pass reloc type to macro_build for 'u'.
5295 (macro): Likewise. For M_LA_AB permit a difference expression
5296 when generating embedded PIC code between an arbitrary symbol and
5297 a symbol in the .text section.
5298 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
5299 BFD_RELOC_PCREL_LO16 to be emitted.

5307 * subsegs.c (subsegs_begin): Call memset with args in the correct
5309 (subseg_get): Clear newly allocated seginfo, set its pointer slots
5310 to NULL instead of 0.

5314 * config/tc-hppa.c (pa_procend): Handle case where label was
5315 defined after the .proc directive.

5339 (hppa_tc_symbol): Likewise.
5341 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
5342 elf_tc_make_sections stuff. It was there to support PA braindamage
5343 which has been fixed, and in the case of elf_tc_make_sections is
5344 redundant with elf_tc_final_processing.
5346 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5348 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

5358 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
5359 value into the file if the fixup will not generate a reloc.
5361 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
5363 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
5364 don't spew remainder of input file in error message.
5365 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
5366 message with reloc type and try to process remainder of file.
5368 * doc/Makefile.in (install-info-as, install-info-gasp): New
5369 targets, now explicitly checking $(srcdir) for info files.
5370 (install-info): Depend on both of them; do nothing more.
5372 Mon Apr 4 17:06:04 1994 Jeffrey A. Law (law@cygnus.com)
5374 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
5376 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5378 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
5379 flag rather than signedp field. Only permit extended range if
5380 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
5381 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
5383 * config/tc-ppc.c (ppc_size): New static variable.
5384 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
5385 (md_begin): If an instruction has a size specific flag set, only
5386 add it if we are assembling that size.
5388 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5390 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
5391 cross section PC relative relocs right for COFF and ELF.
5393 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5395 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
5396 (OBJ_PROCESS_STAB): Don't define.
5398 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5400 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
5401 the type of symbol set symbols which happen to be in the absolute
5402 or undefined section.
5404 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
5406 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
5407 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
5408 and -many (all architectures).
5410 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

5418 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
5419 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
5421 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
5422 branch with an instruction that uses $at, in case the branch is
5424 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
5425 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
5426 to make it pcrel_offset.
5427 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
5428 reloc->address; another gruesome hack to get gas reloc handling to
5431 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5433 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
5436 (emit_insn): New function.
5437 (md_assemble): Call it.
5438 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
5440 (lituse_pending): New variable. Set by anything that generates a
5441 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
5442 tested by code that might want to emit a LITUSE reloc.
5443 (emit_unaligned_io): New function. Currently calls md_assemble,
5444 but it should eventually be converted to generate the insn itself
5445 and call emit_insn directly.
5446 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
5447 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
5448 emit_bis_r): Likewise.
5449 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
5450 (alpha_ip, label get_macro): Don't emit the final instruction if
5452 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
5453 unaligned memory access macros.
5454 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
5455 the value can't be resolved.
5457 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5459 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
5460 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
5461 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
5463 (mips_force_relocation): New function.
5464 (md_apply_fix): Set fixP->fx_done appropriately.

5473 * config/tc-mips.c (enum mips_pic_level): New enum.
5474 (mips_pic): Change from int to enum mips_pic_level. Change all
5475 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
5476 (load_address): Handle EMBEDDED_PIC.
5477 (macro): Handle EMBEDDED_PIC in all PIC cases.
5478 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
5479 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
5480 -non_shared to use NO_PIC (this is how the Irix 5 assembler
5481 works). Do not permit -G with SVR4_PIC.
5482 (s_abicalls): Warn if -G was used, and force -G 0.
5483 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
5484 anything but a.out, not just for ELF. For ECOFF, don't generate a
5485 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
5487 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
5489 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5491 * config/tc-hppa.c (create_new_space): Use ints, not chars as
5492 parameters to avoid losing when compiling with HP CC.

5495 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5497 * Makefile.in (config-stamp): If `defs' is defined, emit a
5498 preprocessor directive to create a macro named by this value into
5499 config.new; don't explicitly go for BFD_ASSEMBLER.
5500 * configure.in: Define `defs', not `BFDDEF'. Set it to
5501 MANY_SEGMENTS for any obj-coffbfd target.
5502 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
5503 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
5505 (LOCAL_LOADLIBES): Deleted.
5506 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
5507 * config/m88kcoff.mt (TDEFINES): Ditto.
5508 * config/ebmon29k.mt: Deleted.
5509 * config/h8300hds.mt: Deleted.
5510 * config/ic960coff.mt: Deleted.
5511 * config/sparc.mt: Deleted.
5512 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
5513 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
5514 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
5515 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

5532 * write.c (symbol_table_frozen): New variable, to be set after
5533 bfd_set_symtab is called.
5534 (dump_section_relocs): Note whether a symbol is a section symbol
5536 (adjust_reloc_syms): For now, always supply an absolute symbol for
5537 fixups without symbols but not yet `done'. Use section_symbol to
5538 get the symbol, instead of going directly for abs_symbol.
5539 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
5540 reloc is not a section symbol and is not in the symbol table.
5541 (set_symtab): New function, broken out from write_object_file.
5542 Counts symbol table instead of relying on an earlier count.
5543 (write_object_file): Call set_symtab, but do it after potentially
5544 invoking the *_frob_file macros. Don't bother counting symbols.
5545 Call symbol_remove, instead of expanding it in place. Moved the
5546 conditionalized `object_file_size' declaration down to
5547 conditionalized block where it's used. When using the absolute
5548 symbol for a fixup without a symbol, set sy_used_in_reloc.
5549 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
5550 the correct symbol for the absolute section.
5552 * subsegs.c (section_symbol): Use symbol_new instead of
5553 symbol_make, since we may want it to go into the symbol table.
5554 Make the new symbol have internal linkage. If
5555 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
5556 symbol with the newly created GAS symbol.

7432 pass new argument for i, j and o cases.
7433 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

7654 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
7655 the table, require that the one without bit 0x1000000 set come
7656 first. Require further that it be case 'b' or 'P'. The a29k
7657 opcode table already meets these constraints.
7658 (machine_ip): When handling case 'i' or 'A', make sure that the

7714 * write.c (write_relocs): For relocs that are pc_relative and
7715 pcrel_offset and not partial_inplace, adjust reloc->addend to

7766 OPTIONAL_REGISTER_PREFIX if either is already defined.
7768 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
7770 * configure.in: Set bfd_gas for all sparc targets. Added facility
7771 for keeping or rejecting configurations still under development;
7772 default is to assume production environment, and reject configs
7773 still being worked on. Mark Elf configurations (except sparc and
7774 i386) as developmental. Deleted cases matching some generic names
7775 in favor of more specific names. (E.g., when we get Alpha
7776 support, we'll still only support VMS for Vax.)

7792 through inclusion of tc-hppa.h. Delete all forward declarations
7793 for functions only used within tc-hppa.c, likewise for structures,
7794 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
7795 conditional code in a few small places.
7797 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
7798 structures, global variables, forward declarations together.

7800 conditional code -- try to group conditional code together
7801 into a few places. Make all functions and variables which
7802 are only used within tc-hppa.c static. PARAMize all functions.
7803 Add comments to functions. Delete unused functions, variables,
7804 #defines, etc. Delete unused members within structures. Delete
7805 ldil;ble hacks -- it is believed they were installed to work
7806 around old gas bugs. Avoid using mixed case for local
7807 functions, variables, and structures. Fix formatting problems
7808 not found by GNU-indent. Add FIXME notices for things which
7809 should be worked on the near future. Delete lots of old
7810 useless (1.36 PA-SOM) code.
7812 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
7813 field of the fixS structure. Needed to build unwind
7814 descriptors correctly.

7839 a multiple of the section alignment rather than always a
7842 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
7843 bits are zero (eg they specify no relocations), then do not even
7844 bother adding their entries to thesymextn section.

7885 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
7886 call strchr for each character to see if it is a special char,
7887 instead add a second loop over special_chars. Set alignment
7888 of text, data and bss sections to 4.
7889 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
7891 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
7892 ELF, since the ELF object format does not have these type of
7893 relocations. Change the abort into as as_bad and return
7894 BFD_RELOC_NONE to silence compiler warnings.
7895 (md_assemble): Keep track of the instruction size. Allow white
7896 space between the $ and the constant for compatibility with older

8907 are also magic, and have special default flag settings.
8908 (obj_elf_frob_symbol): Since the return value from this function

8972 * Extensive changes to permit symbols to contain any expression
8973 type and to delay the computation of the expression until the
8974 value is actually needed. This permits setting symbols to values
8975 calculated based on object code size. Expressions were changed to
8976 no longer be in a section, to stop the overloading of segment and
8977 expression type that previously occurred.
8979 * as.c (big_section, pass1_section, diff_section, absent_section):
8981 (expr_section): Added (used for dummy symbols which hold

9065 (previous_section, previous_subsection): New vars.
9066 (obj_elf_section): Save current place in case DWARF code wants us
9067 to pop back to it. Handle unquoted section name as well as quoted
9068 section name. Don't crash on invalid strings.
9069 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

9181 sy_resolved and sy_resolving single bit fields.
9182 * symbols.c (symbol_new): Don't initialize sy_forward field.

10216 than ECOFF line number information.
10217 (obj_ecoff_stab): Accept non-zero values for stabs line number.

10272 if a label has been seen.
10274 Mon Mar 29 12:56:56 1993 Ian Lance Taylor (ian@cygnus.com)
10276 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
10277 the bottom (make expands variables in dependencies when the
10278 dependencies are read, not when they are used).
10280 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
10281 a29k .bss section; the mondfe program doesn't like it.

10296 (srcdir): Delete second, bogus definition.
10297 (as.info): Look for as-*.texinfo in current directory rather than
10301 * doc/configure.in: Create links to all as-*.texinfo files in the
10302 source directory, if that's not the current directory.
10304 * configure.in (per-host): Accept MIPS host with BSD version
10306 (per-target): Classify i486 as i386. Use generic cpu_type instead
10307 of target_cpu in selecting format etc.

10325 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
10326 process relocs if there aren't any relocs to process. Avoids
10327 malloc/free bug on SCO too.
10329 * as.h: Move local include files below system include files, to
10330 avoid some redefinition complaints on some systems.
10331 (const, volatile): Don't need these conditionally defined if we
10332 use CONST and VOLATILE from ansidecl.h.
10333 (seg_name): Use CONST, not const.
10335 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
10337 * config/tc-mips.c: Reindented to GNU standards.

10341 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
10342 (fixup_segment): Add a29k special case; the linker is not prepared
10343 to see a segment offset here.
10345 * app.c (do_scrub_next_char): Added new state, 10, modifying state
10346 9 to only keep a space in between identifier characters.
10348 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
10350 * Makefile.in: add dvi target; as-$(config).texinfo might live in
10351 srcdir, might be in objdir.
10353 * doc/Makefile.in: dvi depends on as.dvi

10378 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
10380 * app.c (do_scrub_next_char): Added new state, 9, to avoid
10381 dropping a space immediately following an identifier.
10382 * expr.c, write.c: Rewrote assert expressions to not use multiple
10383 lines; I don't think that can be done portably.
10384 * config/tc-mips.c (macro): Use $AT if target register is zero in
10385 load instruction, which it can be for a floating point load.
10387 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)
10389 * write.c (write_contents): Compute the relocs before writing out
10390 the section contents.
10391 * config/obj-ecoff.h, config/obj-ecoff.c: Numerous changes to get
10392 symbol table and values right.
10393 * config/tc-mips.h (LOCAL_LABEL): If OBJ_ECOFF, any label starting
10395 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
10396 by the section vma.
10398 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
10399 z8k-opc.h, not z8k.h.
10401 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
10404 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

10435 * configure.in: Handle all 68300 series chips.
10436 * config/tc-m68k.c: Include config.h.

10438 series cpus as defaults.
10439 (md_parse_option): Accept some m68300 series CPUs as defaults.

10455 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
10456 (struct loc, struct proc, struct file): Moved to tc-mips.c within
10457 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
10458 * config/tc-mips.c: Rearranged for ECOFF support. Added
10459 prototypes for all static functions. Moved existing minimal
10460 debugging format support info #ifndef OBJ_ECOFF blocks.
10461 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
10462 does not support a non sign extended high 16 bits reloc. Adjusted

10509 * make-gas.com: Find obstack.obj if it's not in the current
10511 * read.c (s_ignore): Don't declare is_end_of_line. It's
10512 redundant, and triggers a VMS gcc compiler bug.
10514 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
10515 current segment as an argument. (Ignored in all cases but VMS.)
10516 All callers and definitions changed.
10518 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
10520 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING

10535 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
10536 Call elf_xstabs for .stabs and .xstabs operators.
10538 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
10540 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
10543 * configure.in: mips-bsd configuration was missing format spec.
10546 * Makefile.in (Makefile): Depends on configure.in.
10548 * config/tc-mips.c (append_insn): Don't check for alignment of
10549 frag in memory; alignment of instructions in section is a separate

10569 * config/tc-sparc.c (s_xword): Now call big_cons, so large
10570 constants are accepted, but symbolic values are not. GCC will not
10571 generate the latter currently.
10573 * frags.c (frag_init): New function.
10574 (zero_address_frag, bss_address_frag): Now initialized at run

10608 referencing symbol structure members.
10609 (obj_aout_frob_symbol) [BFD_ASSEMBLER]: New function.
10611 * as.h (struct frag): Reordered a couple of fields for better

10619 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
10620 (fixup_segment): Make sure common-section symbols get treated the
10621 same as undefined symbols.

10627 * tc.h (md_operand, md_convert_frag, tc_headers_hook,
10628 md_section_align, md_undefined_symbol): Don't provide prototypes
10629 if these are defined as macros.
10630 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and
10633 * symbols.c (symbol_new): Argument NAME is now pointer to const.
10634 Simplified STRIP_UNDERSCORE code. Remove assumptions about null
10635 pointers in freshly allocated storage. [BFD_ASSEMBLER]: Get new

10650 given section name and subseg number.
10651 (subseg_set) [BFD_ASSEMBLER]: New function; change to a possibly
10652 new section/subsection.
10654 * read.c: Don't include ctype.h.
10655 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
10656 for now; should be machine-dependent.
10658 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
10659 targets, forcing BFD use.
10661 Wed Feb 17 18:59:03 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
10663 * config/tc-sparc.c: Use PARAMS macro for static function
10664 declarations. Use BFD_RELOC_ macros everywhere, with
10665 compatibility macros declared for non-BFD mode.

10826 * config/tc-sparc.c (architecture_requested, warn_on_bump,
10827 md_relax_table): Use default zero initialization.
10828 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

10841 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
10843 * expr.c (operand): If character other than comma or newline is a
10844 logical end-of-line character, use the newline case.
10845 From Eric Youngdale:
10846 (operand): Set X_add_number field for floating-point numbers.
10847 (operand): Treat zero byte as end-of-operand.
10849 * configure.in (per-target): Look for with_bfd_assembler option.
10850 For now, only accept "no", until the merge is done.
10852 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
10853 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
10854 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
10855 * read.c: Finish conversion to S_* macros in the VMS only
10856 parts of the program. Add "const" modifier to hex_value.
10857 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
10859 * expr.c: Add "const" modifier to hex_value.
10860 * symbols.c: Finish conversion to S_* macros in the VMS only
10861 parts of the program. Add "const" modifier to
10862 md_[long,short]_jump_size. Remove declaration of const_flag
10863 (which will be declared in obj-vms.h).
10864 * write.c: Add "const" modifier to md_[long,short]_jump_size.
10865 Fix arguments to VMS_write_object_file.
10866 * config-gas.com: New file. Script for VMS systems to set up the
10867 configuration to build gas for VMS, and create config.status.
10868 * make-gas.com: Redone to work with new scheme.
10869 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
10871 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
10872 will swap bytes if needed on a big endian system. Use throughout
10874 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
10875 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
10876 types of malformed stabs. Change parsing algorithm so that we are
10877 more certain of having all of the information that we need on hand.
10878 * obj-vms.c (final_forward_reference): New function, used to help
10879 resolve the data types of as many struct elements as possible
10880 when some part of the struct is not fully defined by the compiler.
10881 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
10883 * obj-vms.c (VMS_write_object_file): Define all vtable psects
10884 as symbols as well in the object file. Look for external functions

10894 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
10896 * read.c (s_data): Always use "data_section", since it'll map to
10897 SEG_DATA or SEG_E1 if needed.
10898 (s_lcomm): Likewise with bss_section.
10899 (s_fill): Use memset, not bzero.
10901 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

10921 (seg_name): Declare only if not BFD_ASSEMBLER.
10922 (section_alignment): Declare only if not BFD_ASSEMBLER.
10923 (big_section, reg_section, pass1_section, diff_section,
10924 absent_section, text_section, data_section, bss_section): If
10925 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
10926 mapping to segT enum values.
10927 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
10928 if these are used or defined, if BFD_ASSEMBLER.
10929 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
10930 subseg_new split into two functions.
10931 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.

10945 <mtranle@paris.intellicorp.com>.
10946 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
10947 obj_format coffbfd and gas_target i386coff for target.
10948 (i[34]86-*-isc*): New host (uses sysv).
10949 * config/i386aix.mt: Removed (no longer used).
10950 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
10951 (MINUS_G): Removed.
10952 (LDFLAGS): Added, defined as -shlib.
10953 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
10954 * config/te-sco386.h (LOCAL_LABEL): Don't define.
10955 (DOT_LABEL_PREFIX): Define.
10956 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
10957 name rather than L0\001.

10960 * symbols.c, symbols.h (local_bss_counter): Removed.
10961 * write.c (write_object_file): bss no longer uses
10962 local_bss_counter. Pass correct data and bss size to
10963 VMS_write_object_file.
10964 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
10965 argument, rather than using local_bss_counter.

10969 (size_section): Restored sanity check.
10970 (do_relocs_for): Base section address on s_paddr rather than
10971 computing it. Adjust a29k R_IHIHALF special case to account for
10972 section paddr (used to require paddr to be zero). If there are no
10973 reclos, set s_relptr to 0. Set relocation size in object_headers.
10974 (fill_section): Always set s_vaddr here, removing
10975 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
10976 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
10977 Set STYP_INFO for .comment.
10978 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
10979 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

10982 (do_linenos_for): Set lineno size in object_headers.
10983 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
10984 set s_vaddr here. If string_byte_count remains 4, set it back to
10985 0, and only write strings out if there are some. Call
10986 fill_section before do_relocs_for and do_linenos_for.
10987 (obj_coff_section): Handle optional quoted second argument giving
10988 section characteristics.
10989 (obj_coff_bss): Added to handle .bss.
10990 (obj_coff_ident): Added to handle .ident (puts string in .comment

11010 (do_scrub_next_char): For \", return " not '.
11011 (symbol_chars): Now const.
11013 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
11014 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
11016 * config/obj-coff.h: Don't use #elif.
11018 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
11019 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
11021 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
11023 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

11043 SEG_BSS, fill with NOP_OPCODE.
11044 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
11045 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
11046 using ZERO_BASED_SEGMENTS.
11047 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
11048 never set segment address for SEG_E2 (.bss) and don't write out
11049 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
11050 (obj_coff_endef): Don't merge labels or symbols awaiting forward
11051 definitions, and don't merge tags with non-tags. Check for .bf
11052 rather than just checking whether the second character is b and
11053 the third character is f.
11054 (obj_coff_val): gcc can generate values which we don't handle
11055 correctly; discard information for now, since it only affects the
11056 debugging information.
11057 (tag_find_or_name): Don't insert tags in the symbol table.
11058 (yank_symbols): Don't merge labels.
11059 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

11065 relative addends by the segment vaddr.
11066 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
11067 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

11209 z8000 documentation
11210 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
11213 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
11215 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
11217 * subsegs.h: add extern to segment_info declaration.
11219 * read.h: added extern declarations for comment_chars,
11220 line_comment_chars, and line_separator_chars.
11221 read.c, app.c: removed definitions of comment_chars,
11222 line_comment_chars, and line_separator_chars.

11241 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
11242 constant will not fit in an immediate field.
11243 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
11245 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
11247 * obj-coff.c (callj_table): Delete global variable.
11248 (obj_emit_relocations): Define it locally here, and only if
11249 TC_I960 is defined.
11251 * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.

11278 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
11280 * Support for i386-sysv.
11281 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
11282 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
11283 be used to set them all to zero as was done before.
11284 (fill_section): segment addresses now set in write_object_file.
11285 (fill_section): Don't set STYP_NOLOAD for .bss section.
11286 (fixup_segment): 386 uses strange common symbol format.

11321 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
11323 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
11324 #elif, since it is not supported by old compilers.
11325 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
11326 couple of expressions in tc-m68k.c.
11328 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11330 * read.c (cons): If NO_RELOC is defined, use it.

11336 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
11337 local labels to start with a .) and set REGISTER_PREFIX to %.
11338 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
11340 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
11342 * messages.c: Comment changes.
11344 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

11347 * messages.c: If __STDC__ is not defined, define NO_STDARG.
11349 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
11351 * listing.c (debugging_pseudo): Add stabs and stabn as things to
11354 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
11356 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
11357 sections starting from zero, rather than making them consecutive.
11358 This makes subsequent reloc calculations easier, esp if the object
11359 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
11360 allocate lcomm in .data rather than in .bss. It seems that some
11361 tools can't cope with a non-zero sized bss before linkage.
11363 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11365 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
11366 throughout. That enum no longer means what we thought it meant.
11368 * tc-m68k.c (md_assemble, md_parse_option): Handle new
11369 "-mno-688[58]1" options.
11371 * tc-m68k.c: Added CPU32 support.
11373 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

11384 * Makefile.in (install): if $(tooldir) exists, install as in
11387 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
11389 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
11390 .word is < -32768 or > 32767. The -J flag causes the error to be
11391 ignored. This is to catch over-sized switches generated by gcc on
11392 systems which don't support the broken .word hack.
11393 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
11394 write.c (fixup_segment): check for signed .word overflow if
11395 WARN_SIGNED_OVERFLOW_WORD.
11397 * write.c (fixup_segment): fixed missing parens in expression
11398 checking for byte or word overflow.
11400 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
11401 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
11402 WARN_SIGNED_OVERFLOW_WORD.

11410 * obj-coffbfd.h : added stuff
11411 * tc-i386.c (tc_coff_fix2rtype): new function
11412 * tc-i386.h : new coff defines
11414 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
11416 * input-scrub.c (input_scrub_push): call input_file_begin, not
11418 messages.c (as_perror): print ": " between the passed in error and
11419 the strerror, like perror does.
11421 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

11428 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
11429 Motorola and MIT syntax; gas can now assemble either type of
11431 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
11432 From Steve Chamberlain:
11433 m68kcoff.mt: for m68k COFF.
11434 obj-coffbfd.c: (fixup_mdeps) added
11435 (size_section) removed bad sanity check
11436 (fill_section) added rs_machine_dependent case
11437 (write_object_file) call fixup_mdeps
11438 (fixup_segment) set fx_subsy to 0.
11439 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
11441 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
11444 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

11467 * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
11468 tc-i960.c (md_ri_to_chars): Always output bout object file in
11469 little endian byte order (used to use endianness of host).
11471 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11473 * config/tc-m68k.c (init_table): Now const. Always include 68851
11474 data, so that "bc" is available to 68040 cache instructions.
11475 Added "tt0", "tt1", and 68ec030 variants.
11476 (md_assemble): Complain if 68000 (only) and 68881 are specified.
11477 (enum _register): Added TT0, TT1.
11478 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
11479 line number correctly in "internal error" messages. Don't print
11480 architecture-mismatch message for operand errors.
11482 From Colin Smith (colin@wrs.com):
11483 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
11484 than install_operand.
11486 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)

11493 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
11495 * Makefile.in: defined TARGET_CPU for C code so that it can choose
11496 one element of a family.
11498 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
11500 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
11501 so that we can assemble hand-written libgcc code.
11503 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11505 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
11506 has already been formatted (but may still contain %-characters).
11507 (as_bad): Likewise.
11509 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
11511 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
11512 written with indirection on the last two operands, which can be
11513 either data or address registers. Added a new operand type 'r'
11514 which accepts either register type. Added '(' to notend stuff in
11515 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
11517 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
11519 * as.h (enum _relax_state): Start off at one, not zero, to better
11520 catch uninitialized-variable errors.
11521 (linkrelax): Declare new variable.
11523 * messages.c (warning_count, error_count): Default initializer is
11526 * write.c: Merged some declarations, using PARMS macro.

11528 data_last_frag): No longer static.
11529 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
11530 defined, call it. Change segments before calling fixup_segment.
11531 (relax_align): If linkrelax, provide extra padding.
11533 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
11534 their not having symbols associated.
11536 * tc-i960.c (norelax, instrument_branches): Default initializer is
11538 (linkrelax): Delete variable definition.

11559 Mon Aug 17 15:09:56 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11561 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
11562 being used with args swapped, causing occasional lossage when
11563 refilling buffers after an include file.
11565 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
11567 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
11568 version. Discard bogus DONTDEF version.
11569 (as_warn, as_bad, as_fatal): Likewise.
11571 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
11573 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
11574 selected architecture, print a message saying so and listing what
11575 processors support it, rather than saying "operands mismatch".
11577 Thu Aug 13 13:53:19 1992 Ken Raeburn (raeburn@cygnus.com)

11766 * Makefile.in (install): Install into $(tooldir)/bin, since that's
11767 where gcc looks for it.
11769 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
11771 * Makefile.in: Changed some lines to be less confusing for some

11837 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
11839 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
11841 * expr.c (operand): if can't work out what sort of operand it is,
11842 then look through FLT_CHARS for a hint.
11844 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
11846 * Makefile.in, configure.in: removed traces of namesubdir,
11847 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11848 copyrights to '92, changed some from Cygnus to FSF.
11850 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
11851 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11852 copyrights to '92, changed some from Cygnus to FSF.
11854 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11856 * expr.c: If an expression is single comma, then return with
11857 SEG_ABSENT rather than an error - since the sparc front end does
11858 really strange things with things like fbge,a
11860 * as.h: include bfd.h if using many sections
11861 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
11862 local labels didn't work.
11863 * listing.c (list_symbol_table): don't core dump when there's no
11865 * write.c, write.h: call fix_new with the right number of args on
11867 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
11870 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11872 * app.c: MRI compatibility - allow single quote to start a string.
11873 * as.c: fix typo recently introduced.
11874 * as.h : Don't include aout/reloc.h - it's not right for COFF!
11875 * expr.c: Much rewriting, to accomodate MRI syntax for
11876 expressions. Also easier to read now.
11877 * listing.c: Put back defuns
11878 * read.c: modified to accept MRI syntax, put back listing pseudo
11879 ops so that an assembler built with NO_LISTING ignores list ops
11881 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
11882 machine is a SPARC or a 29K.
11883 * config/obj-aout.c: added s_sect pseudo op
11884 * config/obj-coffbfd.c: lints, set the filehdr flags right and
11885 fill in the timestamp.
11886 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
11887 anymore, define all the relocs which the tc-<x> bit will use so we
11888 can translate from them to the coff types.
11889 * config/tc-a29k.c: reloc_type isn't ane enum any more
11890 * config/tc-m68k.c: Added NO_RELOC definition.
11892 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
11894 * Makefile.in: put header files before C source for TAGS; remove
11895 references to non-existent syscalls.h.
11897 * read.c, write.c subsegs.c: back out the .bss changes.
11899 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
11901 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
11903 * a.out.h: removed.
11905 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
11907 * symbols.c (local_label_name): symbols now start with ^A.
11909 * read.c, subsegs.c, write.c obj-coff.c: added handling of
11910 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
11911 generate these sections. .align: will use NOP_OPCODE or 0
11912 for padding. This is just for being nice to the
11915 * expr.c (operand): changed to generate local label "\001L0"
11916 starting with a ^A so that it is recognized as a local label.
11918 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
11920 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
11921 i/o opcodes - inb, inw, outb and outw. string manipulation with
11922 att syntax - scmp, slod, smov, ssca, ssto.
11924 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
11925 to just after .file .
11927 In obj_crawl_symbol_chain() where it tries to put the external
11928 symbols apart, with the condition:
11929 (!S_IS_DEFINED(symbolP) &&
11930 !S_IS_DEBUG(symbolP) &&
11931 !SF_GET_STATICS(symbolP))
11932 it was moving too many symbols out. So I switch it back to the
11934 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
11936 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
11937 so that we don't use the F_RELFLG which make the linker complain
11938 that somebody has stripped the relocation info.
11940 Also, the AIX ld program require that the relocation table
11941 is sorted by r_vaddr like the standard ATT assembler does.
11943 [he also changed the sizeof(struct ...)'s into the coff
11944 style FOOSZ macros. I'm not sure this is right, but I can't
11945 remember why. xoxorich.]
11947 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
11949 * Makefile.in, configure.in, doc: use the doc. Build it, install

11954 * read.c: white space and comments only.
11956 * configure.in: use the new atof-ns32.c for ns32k.
11958 * write.c: comment change only.
11960 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
11961 aren't yet integrated.
11963 * tc-i860.[hc]: blew off the dust. Something must still be done
11964 about conflicting relocation types.
11966 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
11969 * tc-i960.c, tc-sparc.c: white space and comments only.
11971 * tc-a29k.h: delete duplicate macro definition.
11973 * new file atof-ns32k.c copied from hack's last unreleased gas.
11975 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
11977 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
11980 * nearly everything. flush ChangeLog, package as gas-1.92.1.
11981 ChangeLog's prior to this are sketchy at best. I have logs.
11982 They just aren't ChangeLogs.
