3276 * config/tc-mips.c (md_pseudo_table): If OBJ_ELF, handle .section.
3277 (s_elf_section): New static function.
3278 * ecoff.c (ecoff_build_symbols): Don't abort if we don't recognize

3283 * config/tc-hppa.c (md_apply_fix): Set new_val to 8 for all
3284 fixups to branch instructions (not just pc-relative ones) which

3314 * config/tc-hppa.c: Eliminate all uses of fx_addnumber.
3315 (tc_gen_reloc): Simplify. It's no longer necessary to set a
3316 reloc's addend field to zero for function symbols.
3317 (md_apply_fix): Simplify. For fixups which will require a SOM
3318 reloc, just clear out the necessary bits in the output file.

3322 * Makefile.in (BISON): Use bison -y, not bison.

3336 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
3338 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
3339 it's better to use the one in libiberty.
3341 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3343 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
3344 change; it breaks the rs6000 support, and doesn't seem to be
3347 Wed Oct 12 11:56:50 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
3349 * config/tc-i386.h,te-netbsd532.h (TARGET_FORMAT): Changed to

3355 rather than explicitly adding the frag address.
3356 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark
3357 the end of the line numbers; this replaces the zero entry which
3358 used to be added by coff_add_linesym, removed Oct 7.
3359 (coff_adjust_section_syms): Ignore sections with no seginfo.
3361 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3363 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a
3364 "stage" symlink to the appropriate stage* directory, and use it
3365 instead in the -B options.
3366 (comparison): Revert yesterday's change.
3368 Tue Oct 11 16:48:11 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3370 * config/tc-sparc.c (tc_gen_reloc): For non-a.out relocations, if

3373 Tue Oct 11 15:24:00 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
3375 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
3376 for an embedded PIC switch expression, since the definition of
3377 S_IS_LOCAL was changed.
3379 Tue Oct 11 15:05:11 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
3381 * Makefile.in (comparison): When comparing as.new or gasp.new, try
3382 running the binary through sed to avoid differences due to
3383 "stage1" or "stage2" having been written into the binary.
3385 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
3387 ELF symbol size handling, based on code from Eric Youngdale:
3388 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an

3395 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
3397 (obj_elf_size): Deleted unused code. If size is non-reducible
3398 expression, allocate some storage for the sy_obj field and copy
3400 (elf_frob_symbol): New function. Computes sizes, calls
3401 ecoff_frob_symbol if appropriate.
3403 * write.c (fixup_segment): For i386 elf and coff (for now), don't
3404 add in value of symbol from another defined section of the file.
3406 Fri Oct 7 17:54:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

3450 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
3452 (diststuff): New target; builds DISTSTUFF.
3453 (realclean): Separate target, depend on clean and distclean, then
3455 * make-gas.com: Deleted.

3458 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
3460 (i386_operand): Don't look up section symbol for
3462 (reloc): Always permit return of 8- and 16-bit relocation types.
3463 Add a space after "pc-relative" in the error message.
3464 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
3465 BFD_RELOC_386_GOTOFF relocs.

3469 (TC_VALIDATE_FIX): New macro -- call it.
3470 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.

3473 it rather than stdarg.h.
3475 * write.h (struct fix): Added new bitfield fx_plt, for fixups
3476 referring to PLT entries.
3477 * write.c (fix_new_internal): Initialize fx_plt to zero.
3478 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
3479 Don't adjust fx_offset by frag address, since S_GET_VALUE now
3480 includes the frag address.
3481 (fixup_segment): Changed local var PCREL to type int, added PLT.
3482 If PC-relative fixup refers to a PLT entry for a symbol in the
3483 current section, don't reduce it.

3489 and after processing.
3490 (print_fixup): Added prototype. Show address on first line. Show
3491 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if

3505 Show fx_r_type and fx_addsy fields.
3507 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3509 * configure.in: Set bfd_gas for all sparc targets in one place,
3510 instead of separately for each. Correctly handle user-supplied
3511 "--enable-bfd-gas" option.
3513 * gdbinit.in: Move "break abort" to end, in case gdb complains.
3515 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
3518 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
3519 processing if add_symbol is undefined or in expr_section.
3520 (resolve_symbol_value, case O_add): For symbol plus
3521 constant-valued symbol, convert to O_symbol and re-reduce.
3522 (S_GET_VALUE): If symbol needs resolving, resolve it.
3523 (indent_level): No longer static.
3524 (print_symbol_value_1): Don't print frag address if it matches
3525 zero_address_frag. Don't print "resolving" if already resolved.

3528 (print_expr_1): Fix whitespace before printing X_add_number.
3530 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
3531 not symbol_new, for symbols holding expression values.
3532 * expr.h (make_expr_symbol): Move declaration here.
3533 * write.c (fix_new_exp): Handle O_add by creating an
3534 expression-valued symbol, and calling fix_new_exp recursively.
3535 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
3536 undefined symbol and a constant, fold the constant into the fixup,
3537 and refer to the undefined symbol directly. Then process the
3538 fixup again from scratch.
3539 (write_object_file): Before calling adjust_reloc_syms, make a pass
3540 through the symbol list trying to resolve values.
3542 * write.c (print_fixup): New routine, for debugging.
3543 (write_relocs): Call bfd_install_relocation. Deleted various
3544 hacks for working around problems with bfd_perform_relocation.
3546 * Makefile.in (VERSION): Update to 2.4.90.
3548 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3550 * Makefile.in (gasp.o): Depends upon config.h.
3552 * config/tc-mips.c: Include subsegs.h.
3553 (md_apply_fix): If an unconditional b or bal overflows, and we are
3554 not assembling PIC code, replace it with a j or jal.
3556 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
3557 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
3559 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3561 * write.c (write_relocs): Add file name and line number to
3562 as_fatal calls. Handle bfd_reloc_overflow case specifically when
3563 RELOC_EXPANSION_POSSIBLE.
3565 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3567 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
3568 here. Use them for deciding which PRINTF*LIKE macro definitions
3570 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
3571 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
3572 default definitions matching what we were doing before.
3573 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
3574 always use the varargs form if not using stdarg. It's safe to
3575 always use vfprintf, because libiberty will provide it if the
3576 native system doesn't. Also, always make format be const.
3577 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
3579 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

3592 (listing_newline): Check filename as well as line number when
3593 deciding whether to record it.
3594 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
3595 false (if defined) as well as checking for reg_section.
3596 (listing_listing): Iterate fetching lines while line number is too
3597 low, and we haven't run off the end of the input file.
3599 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
3601 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
3603 * ecoff.c (ecoff_generate_asm_lineno): check if
3604 current_stabs_filename is NULL before strcmp.
3605 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
3608 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3610 * config/ho-*.h: Now-unused files deleted.
3612 * symbols.c (copy_symbol_attributes): New function. Copies BFD
3613 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
3614 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
3615 zero. Don't call obj_frob_forward_symbol.
3616 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
3617 X_add_number is zero.
3618 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
3620 * config/tc-i960.c: Lots of whitespace, comment reformatting,
3622 (strchr): Don't declare.
3623 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
3624 md_estimate_size_before_relax, md_ri_to_chars,
3625 md_create_short_jump, md_create_long_jump.
3626 (brtab_emit): Use data_section, not SEG_DATA.
3628 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3630 * config/vms-conf.h: new file, manually derived from conf.in.
3631 * config-gas.com: use it, and eliminate obsolete "host.h".
3633 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3635 * config/tc-ppc.c (ppc_current_block): New static variable.
3636 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
3637 ppc_current_block. Don't move around any stab symbol, just those
3639 (ppc_bs): Set ppc_current_block.
3640 (ppc_es): Clear ppc_current_block.
3641 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
3642 from the csect of the enclosing block.
3644 * config/tc-mips.c (insns_since_cache_access): Remove.
3645 (append_insn): Remove setting of insns_since_cache_access, and
3646 special 4600 handling; it turns out not to be required.
3648 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3650 * config/tc-mips.c (md_shortopts): Remove E.
3651 (md_longopts): Add EB and EL.
3652 (md_parse_option): Handle -EB and -EL as separate options, rather
3653 than as a single -E option with an argument.
3655 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
3657 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
3658 involving global symbols too.
3660 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3662 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
3664 * configure.in: Test for remove, not delete. Fix cross-assembler
3666 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
3669 * read.c (pseudo_set, case O_symbol): If
3670 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
3671 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
3672 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
3674 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
3676 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
3677 many others): new macros; values obtained from "DSTRECRDS.SDL".
3678 * config/obj-vms.h (various): use them.
3679 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
3680 representation (only enum bitfields can avoid being bitstrings).
3681 (bitfield_suffix, setup_basic_type): new routines.
3682 (VMS_typedef_parse): use them. Now recognize bitfields of all
3683 integral types, not just type `int'. Caveat: the representation
3684 used for bitfields still does not work for objects placed in
3685 registers, and gcc's optimizer sometimes puts small structs there.
3687 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3689 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
3690 bit from const_flag.
3691 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
3692 (tc_frob_label): define this to call vms_check_for_special_label,
3693 and declare the latter.
3694 * config/obj-vms.c (vax_g_doubles): declare this file-scope
3696 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
3697 (vms_check_for_special_label): new routine (tc_frob_label).
3698 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
3699 and `gcc2_compiled.' labels; they won't reach here any more.
3700 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
3701 double', use `vax_g_doubles' flag to select type of double.
3702 (VMS_write_object_file) [traceback setup]: don't pass symbols
3703 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
3704 and TBT_Routine_End functions.
3706 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
3708 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
3709 S_GET_VALUE() to avoid many repeated function calls.
3710 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
3711 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
3712 gets requested. [All the HACK_DEC_C_STARTUP code appears to
3713 be obsolete; gcc does it automatically for vms target. It's
3714 also misnamed, because it is for the "VAX C" run-time library,
3715 not the newer "DEC C" one which has much different startup code.]
3716 {various}: use `S_SET_xxx(symbol,new_value)' rather than
3717 `S_GET_xxx(symbol) = new_value'.
3719 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

4716 $8,%hi(foo); lw $8,%lo(foo)($8)'' work correctly.
4718 Mon Jun 13 12:08:52 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4720 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
4721 to put a common symbol in a set.

4766 * read.c (emit_expr): Use memset to zero out memory, rather than
4767 going through md_number_to_chars. This permits handling symbolic

4820 m68040_control_regs, m68060_control_regs): New arrays.
4821 (control_regs): New pointer.
4822 (m68k_ip): Use control_regs instead of testing CPU every time.
4823 Use last_movec_reg too. In error messages, handle 68060, and
4824 print 68060 for mfloat, too.
4825 (m68k_init_after_args): Handle "68060". Use m68040up for making
4826 m68851 choice. Set control_regs.

5114 * listing.c (list_symbol_table): Print "NO DEFINED SYMBOLS" and
5115 "NO UNDEFINED SYMBOLS" if there aren't any, instead of displaying
5116 the header with an empty list.
5118 * config/obj-coffbfd.c (fill_section): Check COFF_NOLOAD_PROBLEM
5119 also before setting STYP_NOLOAD for .bss section.
5121 * config/tc-m68k.c (flag_reg_prefix_optional): New variable.
5122 Initialized to value of REGISTER_PREFIX_OPTIONAL, if defined, or
5124 (m68k_reg_parse): If flag_reg_prefix_optional is set, permit
5125 register prefix to be absent.
5126 (m68k_ip_op): Accept `&' also for immediate constants.
5127 (insert_reg): Don't bother with (two!?) sanity checks of the
5128 symbol table when inserting each register.

5130 flag_reg_prefix_optional if "register-prefix-optional" is passed.
5131 * config/tc-m68k.h (REGISTER_PREFIX): Always define if not already
5133 (OPTIONAL_REGISTER_PREFIX): Don't define.
5134 (REGISTER_PREFIX_OPTIONAL): If not already defined, define as zero
5135 or one depending on M68KCOFF.

5138 * config/tc-m68k.c (DATA, ADDR, SP, FPREG, COPNUM, BAD, BAC):
5139 Define as macros instead of enumerators, since the Apollo compiler
5140 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum
5142 (make_pcrel_absolute) [NO_PCREL_RELOCS]: New function.
5143 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
5144 R_DIR16, and R_DIR32 relocs.
5145 * config/tc-m68k.h [TE_APOLLO] (COFF_MAGIC, COFF_AOUTHDR_MAGIC):
5146 Use Apollo versions.
5147 [TE_APOLLO] (OBJ_COFF_OMIT_OPTIONAL_HEADER): Undefine. That is,

5154 * config/tc-m68k.h (m68k_init_after_args): Declare.
5155 (tc_init_after_args): Define as m68k_init_after_args.
5156 * config/tc-m68k.c (m68k_init_after_args): New function,
5157 containing one-shot code from md_assemble. Added warning for
5158 combination of 68040 and 68851.

5178 * listing.c (list_symbol_table): Don't print register symbols as
5181 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
5182 underscores, since symbol_new will already have done it.

5185 * as.c (main): If tc_init_after_args is defined, invoke it after
5186 all arguments have been processed.
5188 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
5189 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
5190 section instead of .text. Call create_target_segments.
5191 * read.c (demand_copy_string): No longer static.
5193 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5195 * config/tc-mips.c (append_insn): Permit branches to be switched
5196 with the preceding instruction even if .set nobopt has been seen.
5197 .set nobopt actually controls whether to bring up an instruction
5198 from the branch target, which gas does not currently support.
5200 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5202 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

5251 address zero, insert a dummy line to compensate.
5253 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
5256 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5258 * expr.c (operand): Try to parse "0f" and "0b" sequences as
5259 floating point and binary numbers respectively; if it doesn't
5260 work, treat them as local labels.
5262 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
5263 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
5265 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
5267 * vmsconf.sh: In generated file, get ".obj" suffix right, build
5268 source files from other directories into objects in the current
5269 directory, and specify PSECT attributes explicitly to linker.
5270 Also added missing label.
5271 * Makefile.in (stamp-mk.com): Reference new variable

5289 argument, the reloc type.
5290 (load_register): Pass reloc type to macro_build for 'u'.
5291 (macro): Likewise. For M_LA_AB permit a difference expression
5292 when generating embedded PIC code between an arbitrary symbol and

5303 * subsegs.c (subsegs_begin): Call memset with args in the correct
5305 (subseg_get): Clear newly allocated seginfo, set its pointer slots

5335 (hppa_tc_symbol): Likewise.
5337 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
5338 elf_tc_make_sections stuff. It was there to support PA braindamage
5339 which has been fixed, and in the case of elf_tc_make_sections is
5340 redundant with elf_tc_final_processing.
5342 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5344 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

5360 don't spew remainder of input file in error message.
5361 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
5362 message with reloc type and try to process remainder of file.
5364 * doc/Makefile.in (install-info-as, install-info-gasp): New
5365 targets, now explicitly checking $(srcdir) for info files.
5366 (install-info): Depend on both of them; do nothing more.

5370 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
5372 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5374 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
5375 flag rather than signedp field. Only permit extended range if
5376 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
5377 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
5379 * config/tc-ppc.c (ppc_size): New static variable.
5380 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
5381 (md_begin): If an instruction has a size specific flag set, only
5382 add it if we are assembling that size.
5384 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5386 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
5387 cross section PC relative relocs right for COFF and ELF.
5389 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5391 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
5392 (OBJ_PROCESS_STAB): Don't define.

5396 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
5397 the type of symbol set symbols which happen to be in the absolute
5398 or undefined section.
5400 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
5402 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
5403 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
5404 and -many (all architectures).

5415 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
5417 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
5418 branch with an instruction that uses $at, in case the branch is
5420 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
5421 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
5422 to make it pcrel_offset.
5423 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
5424 reloc->address; another gruesome hack to get gas reloc handling to
5427 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5429 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
5432 (emit_insn): New function.
5433 (md_assemble): Call it.
5434 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
5436 (lituse_pending): New variable. Set by anything that generates a
5437 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
5438 tested by code that might want to emit a LITUSE reloc.
5439 (emit_unaligned_io): New function. Currently calls md_assemble,
5440 but it should eventually be converted to generate the insn itself
5441 and call emit_insn directly.
5442 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
5443 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
5444 emit_bis_r): Likewise.
5445 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
5446 (alpha_ip, label get_macro): Don't emit the final instruction if
5448 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
5449 unaligned memory access macros.
5450 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
5451 the value can't be resolved.
5453 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5455 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
5456 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

5469 * config/tc-mips.c (enum mips_pic_level): New enum.
5470 (mips_pic): Change from int to enum mips_pic_level. Change all
5471 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
5472 (load_address): Handle EMBEDDED_PIC.
5473 (macro): Handle EMBEDDED_PIC in all PIC cases.
5474 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
5475 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
5476 -non_shared to use NO_PIC (this is how the Irix 5 assembler
5477 works). Do not permit -G with SVR4_PIC.
5478 (s_abicalls): Warn if -G was used, and force -G 0.
5479 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
5480 anything but a.out, not just for ELF. For ECOFF, don't generate a
5481 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
5483 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
5485 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5487 * config/tc-hppa.c (create_new_space): Use ints, not chars as

5491 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5493 * Makefile.in (config-stamp): If `defs' is defined, emit a
5494 preprocessor directive to create a macro named by this value into
5495 config.new; don't explicitly go for BFD_ASSEMBLER.
5496 * configure.in: Define `defs', not `BFDDEF'. Set it to
5497 MANY_SEGMENTS for any obj-coffbfd target.
5498 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
5499 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
5501 (LOCAL_LOADLIBES): Deleted.
5502 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
5503 * config/m88kcoff.mt (TDEFINES): Ditto.
5504 * config/ebmon29k.mt: Deleted.
5505 * config/h8300hds.mt: Deleted.
5506 * config/ic960coff.mt: Deleted.
5507 * config/sparc.mt: Deleted.
5508 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
5509 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
5510 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
5511 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

5529 bfd_set_symtab is called.
5530 (dump_section_relocs): Note whether a symbol is a section symbol
5532 (adjust_reloc_syms): For now, always supply an absolute symbol for
5533 fixups without symbols but not yet `done'. Use section_symbol to
5534 get the symbol, instead of going directly for abs_symbol.
5535 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
5536 reloc is not a section symbol and is not in the symbol table.
5537 (set_symtab): New function, broken out from write_object_file.
5538 Counts symbol table instead of relying on an earlier count.
5539 (write_object_file): Call set_symtab, but do it after potentially
5540 invoking the *_frob_file macros. Don't bother counting symbols.
5541 Call symbol_remove, instead of expanding it in place. Moved the
5542 conditionalized `object_file_size' declaration down to
5543 conditionalized block where it's used. When using the absolute
5544 symbol for a fixup without a symbol, set sy_used_in_reloc.
5545 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
5546 the correct symbol for the absolute section.
5548 * subsegs.c (section_symbol): Use symbol_new instead of
5549 symbol_make, since we may want it to go into the symbol table.
5550 Make the new symbol have internal linkage. If
5551 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
5552 symbol with the newly created GAS symbol.

7428 pass new argument for i, j and o cases.
7429 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

7650 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
7651 the table, require that the one without bit 0x1000000 set come

7710 * write.c (write_relocs): For relocs that are pc_relative and
7711 pcrel_offset and not partial_inplace, adjust reloc->addend to

7762 OPTIONAL_REGISTER_PREFIX if either is already defined.
7764 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
7766 * configure.in: Set bfd_gas for all sparc targets. Added facility
7767 for keeping or rejecting configurations still under development;
7768 default is to assume production environment, and reject configs
7769 still being worked on. Mark Elf configurations (except sparc and
7770 i386) as developmental. Deleted cases matching some generic names
7771 in favor of more specific names. (E.g., when we get Alpha
7772 support, we'll still only support VMS for Vax.)

7788 through inclusion of tc-hppa.h. Delete all forward declarations
7789 for functions only used within tc-hppa.c, likewise for structures,
7790 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
7791 conditional code in a few small places.
7793 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
7794 structures, global variables, forward declarations together.

7796 conditional code -- try to group conditional code together
7797 into a few places. Make all functions and variables which
7798 are only used within tc-hppa.c static. PARAMize all functions.
7799 Add comments to functions. Delete unused functions, variables,
7800 #defines, etc. Delete unused members within structures. Delete
7801 ldil;ble hacks -- it is believed they were installed to work
7802 around old gas bugs. Avoid using mixed case for local
7803 functions, variables, and structures. Fix formatting problems
7804 not found by GNU-indent. Add FIXME notices for things which
7805 should be worked on the near future. Delete lots of old
7806 useless (1.36 PA-SOM) code.
7808 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
7809 field of the fixS structure. Needed to build unwind
7810 descriptors correctly.

7835 a multiple of the section alignment rather than always a
7838 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
7839 bits are zero (eg they specify no relocations), then do not even
7840 bother adding their entries to thesymextn section.

7881 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
7882 call strchr for each character to see if it is a special char,
7883 instead add a second loop over special_chars. Set alignment
7884 of text, data and bss sections to 4.
7885 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
7887 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
7888 ELF, since the ELF object format does not have these type of
7889 relocations. Change the abort into as as_bad and return
7890 BFD_RELOC_NONE to silence compiler warnings.
7891 (md_assemble): Keep track of the instruction size. Allow white
7892 space between the $ and the constant for compatibility with older

8903 are also magic, and have special default flag settings.
8904 (obj_elf_frob_symbol): Since the return value from this function

8968 * Extensive changes to permit symbols to contain any expression
8969 type and to delay the computation of the expression until the
8970 value is actually needed. This permits setting symbols to values
8971 calculated based on object code size. Expressions were changed to
8972 no longer be in a section, to stop the overloading of segment and
8973 expression type that previously occurred.
8975 * as.c (big_section, pass1_section, diff_section, absent_section):
8977 (expr_section): Added (used for dummy symbols which hold

9061 (previous_section, previous_subsection): New vars.
9062 (obj_elf_section): Save current place in case DWARF code wants us
9063 to pop back to it. Handle unquoted section name as well as quoted
9064 section name. Don't crash on invalid strings.
9065 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

9177 sy_resolved and sy_resolving single bit fields.
9178 * symbols.c (symbol_new): Don't initialize sy_forward field.

10212 than ECOFF line number information.
10213 (obj_ecoff_stab): Accept non-zero values for stabs line number.

10268 if a label has been seen.
10270 Mon Mar 29 12:56:56 1993 Ian Lance Taylor (ian@cygnus.com)
10272 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
10273 the bottom (make expands variables in dependencies when the
10274 dependencies are read, not when they are used).
10276 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
10277 a29k .bss section; the mondfe program doesn't like it.

10292 (srcdir): Delete second, bogus definition.
10293 (as.info): Look for as-*.texinfo in current directory rather than
10297 * doc/configure.in: Create links to all as-*.texinfo files in the
10298 source directory, if that's not the current directory.
10300 * configure.in (per-host): Accept MIPS host with BSD version
10302 (per-target): Classify i486 as i386. Use generic cpu_type instead
10303 of target_cpu in selecting format etc.

10321 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
10322 process relocs if there aren't any relocs to process. Avoids
10323 malloc/free bug on SCO too.
10325 * as.h: Move local include files below system include files, to
10326 avoid some redefinition complaints on some systems.
10327 (const, volatile): Don't need these conditionally defined if we
10328 use CONST and VOLATILE from ansidecl.h.
10329 (seg_name): Use CONST, not const.
10331 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
10333 * config/tc-mips.c: Reindented to GNU standards.
10335 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
10337 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
10338 (fixup_segment): Add a29k special case; the linker is not prepared
10339 to see a segment offset here.
10341 * app.c (do_scrub_next_char): Added new state, 10, modifying state
10342 9 to only keep a space in between identifier characters.
10344 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
10346 * Makefile.in: add dvi target; as-$(config).texinfo might live in
10347 srcdir, might be in objdir.
10349 * doc/Makefile.in: dvi depends on as.dvi

10374 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
10376 * app.c (do_scrub_next_char): Added new state, 9, to avoid
10377 dropping a space immediately following an identifier.
10378 * expr.c, write.c: Rewrote assert expressions to not use multiple
10379 lines; I don't think that can be done portably.
10380 * config/tc-mips.c (macro): Use $AT if target register is zero in
10381 load instruction, which it can be for a floating point load.
10383 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)
10385 * write.c (write_contents): Compute the relocs before writing out
10386 the section contents.
10387 * config/obj-ecoff.h, config/obj-ecoff.c: Numerous changes to get
10388 symbol table and values right.
10389 * config/tc-mips.h (LOCAL_LABEL): If OBJ_ECOFF, any label starting
10391 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
10392 by the section vma.
10394 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
10395 z8k-opc.h, not z8k.h.
10397 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
10400 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

10431 * configure.in: Handle all 68300 series chips.
10432 * config/tc-m68k.c: Include config.h.

10434 series cpus as defaults.
10435 (md_parse_option): Accept some m68300 series CPUs as defaults.

10451 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
10452 (struct loc, struct proc, struct file): Moved to tc-mips.c within
10453 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
10454 * config/tc-mips.c: Rearranged for ECOFF support. Added
10455 prototypes for all static functions. Moved existing minimal
10456 debugging format support info #ifndef OBJ_ECOFF blocks.
10457 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
10458 does not support a non sign extended high 16 bits reloc. Adjusted

10505 * make-gas.com: Find obstack.obj if it's not in the current
10507 * read.c (s_ignore): Don't declare is_end_of_line. It's
10508 redundant, and triggers a VMS gcc compiler bug.
10510 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
10511 current segment as an argument. (Ignored in all cases but VMS.)
10512 All callers and definitions changed.
10514 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
10516 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING

10531 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
10532 Call elf_xstabs for .stabs and .xstabs operators.
10534 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
10536 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
10539 * configure.in: mips-bsd configuration was missing format spec.
10542 * Makefile.in (Makefile): Depends on configure.in.
10544 * config/tc-mips.c (append_insn): Don't check for alignment of
10545 frag in memory; alignment of instructions in section is a separate

10565 * config/tc-sparc.c (s_xword): Now call big_cons, so large
10566 constants are accepted, but symbolic values are not. GCC will not
10567 generate the latter currently.
10569 * frags.c (frag_init): New function.
10570 (zero_address_frag, bss_address_frag): Now initialized at run

10604 referencing symbol structure members.
10605 (obj_aout_frob_symbol) [BFD_ASSEMBLER]: New function.
10607 * as.h (struct frag): Reordered a couple of fields for better

10615 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
10616 (fixup_segment): Make sure common-section symbols get treated the
10617 same as undefined symbols.

10623 * tc.h (md_operand, md_convert_frag, tc_headers_hook,
10624 md_section_align, md_undefined_symbol): Don't provide prototypes
10625 if these are defined as macros.
10626 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and
10629 * symbols.c (symbol_new): Argument NAME is now pointer to const.

10646 given section name and subseg number.
10647 (subseg_set) [BFD_ASSEMBLER]: New function; change to a possibly
10648 new section/subsection.
10650 * read.c: Don't include ctype.h.
10651 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
10652 for now; should be machine-dependent.
10654 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
10655 targets, forcing BFD use.
10657 Wed Feb 17 18:59:03 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
10659 * config/tc-sparc.c: Use PARAMS macro for static function
10660 declarations. Use BFD_RELOC_ macros everywhere, with
10661 compatibility macros declared for non-BFD mode.

10822 * config/tc-sparc.c (architecture_requested, warn_on_bump,
10823 md_relax_table): Use default zero initialization.
10824 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

10837 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
10839 * expr.c (operand): If character other than comma or newline is a
10840 logical end-of-line character, use the newline case.
10841 From Eric Youngdale:
10842 (operand): Set X_add_number field for floating-point numbers.
10843 (operand): Treat zero byte as end-of-operand.
10845 * configure.in (per-target): Look for with_bfd_assembler option.
10846 For now, only accept "no", until the merge is done.
10848 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
10849 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
10850 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
10851 * read.c: Finish conversion to S_* macros in the VMS only
10852 parts of the program. Add "const" modifier to hex_value.
10853 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
10855 * expr.c: Add "const" modifier to hex_value.
10856 * symbols.c: Finish conversion to S_* macros in the VMS only
10857 parts of the program. Add "const" modifier to
10858 md_[long,short]_jump_size. Remove declaration of const_flag
10859 (which will be declared in obj-vms.h).
10860 * write.c: Add "const" modifier to md_[long,short]_jump_size.
10861 Fix arguments to VMS_write_object_file.
10862 * config-gas.com: New file. Script for VMS systems to set up the
10863 configuration to build gas for VMS, and create config.status.
10864 * make-gas.com: Redone to work with new scheme.
10865 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
10867 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
10868 will swap bytes if needed on a big endian system. Use throughout
10870 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
10871 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
10872 types of malformed stabs. Change parsing algorithm so that we are
10873 more certain of having all of the information that we need on hand.
10874 * obj-vms.c (final_forward_reference): New function, used to help
10875 resolve the data types of as many struct elements as possible
10876 when some part of the struct is not fully defined by the compiler.
10877 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
10879 * obj-vms.c (VMS_write_object_file): Define all vtable psects
10880 as symbols as well in the object file. Look for external functions

10890 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
10892 * read.c (s_data): Always use "data_section", since it'll map to
10893 SEG_DATA or SEG_E1 if needed.
10894 (s_lcomm): Likewise with bss_section.
10895 (s_fill): Use memset, not bzero.
10897 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10899 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

10916 otherwise, use seg_name array.
10917 (seg_name): Declare only if not BFD_ASSEMBLER.
10918 (section_alignment): Declare only if not BFD_ASSEMBLER.
10919 (big_section, reg_section, pass1_section, diff_section,
10920 absent_section, text_section, data_section, bss_section): If
10921 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
10922 mapping to segT enum values.
10923 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
10924 if these are used or defined, if BFD_ASSEMBLER.
10925 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
10926 subseg_new split into two functions.
10927 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.

10941 <mtranle@paris.intellicorp.com>.
10942 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
10943 obj_format coffbfd and gas_target i386coff for target.
10944 (i[34]86-*-isc*): New host (uses sysv).
10945 * config/i386aix.mt: Removed (no longer used).
10946 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
10947 (MINUS_G): Removed.
10948 (LDFLAGS): Added, defined as -shlib.
10949 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
10950 * config/te-sco386.h (LOCAL_LABEL): Don't define.
10951 (DOT_LABEL_PREFIX): Define.
10952 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
10953 name rather than L0\001.

10956 * symbols.c, symbols.h (local_bss_counter): Removed.
10957 * write.c (write_object_file): bss no longer uses
10958 local_bss_counter. Pass correct data and bss size to
10959 VMS_write_object_file.
10960 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
10961 argument, rather than using local_bss_counter.

10965 (size_section): Restored sanity check.
10966 (do_relocs_for): Base section address on s_paddr rather than
10967 computing it. Adjust a29k R_IHIHALF special case to account for
10968 section paddr (used to require paddr to be zero). If there are no
10969 reclos, set s_relptr to 0. Set relocation size in object_headers.
10970 (fill_section): Always set s_vaddr here, removing
10971 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
10972 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
10973 Set STYP_INFO for .comment.
10974 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
10975 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

10978 (do_linenos_for): Set lineno size in object_headers.
10979 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
10980 set s_vaddr here. If string_byte_count remains 4, set it back to
10981 0, and only write strings out if there are some. Call
10982 fill_section before do_relocs_for and do_linenos_for.
10983 (obj_coff_section): Handle optional quoted second argument giving
10984 section characteristics.
10985 (obj_coff_bss): Added to handle .bss.
10986 (obj_coff_ident): Added to handle .ident (puts string in .comment

11006 (do_scrub_next_char): For \", return " not '.
11007 (symbol_chars): Now const.
11009 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
11010 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
11012 * config/obj-coff.h: Don't use #elif.
11014 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
11015 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
11017 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
11019 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

11039 SEG_BSS, fill with NOP_OPCODE.
11040 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
11041 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
11042 using ZERO_BASED_SEGMENTS.
11043 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
11044 never set segment address for SEG_E2 (.bss) and don't write out
11045 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
11046 (obj_coff_endef): Don't merge labels or symbols awaiting forward
11047 definitions, and don't merge tags with non-tags. Check for .bf
11048 rather than just checking whether the second character is b and
11049 the third character is f.
11050 (obj_coff_val): gcc can generate values which we don't handle
11051 correctly; discard information for now, since it only affects the
11052 debugging information.
11053 (tag_find_or_name): Don't insert tags in the symbol table.
11054 (yank_symbols): Don't merge labels.
11055 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

11205 z8000 documentation
11206 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
11209 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
11211 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
11213 * subsegs.h: add extern to segment_info declaration.
11215 * read.h: added extern declarations for comment_chars,
11216 line_comment_chars, and line_separator_chars.
11217 read.c, app.c: removed definitions of comment_chars,
11218 line_comment_chars, and line_separator_chars.

11237 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
11238 constant will not fit in an immediate field.

11243 * obj-coff.c (callj_table): Delete global variable.
11244 (obj_emit_relocations): Define it locally here, and only if
11245 TC_I960 is defined.
11247 * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.

11274 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
11276 * Support for i386-sysv.
11277 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
11278 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
11279 be used to set them all to zero as was done before.
11280 (fill_section): segment addresses now set in write_object_file.
11281 (fill_section): Don't set STYP_NOLOAD for .bss section.
11282 (fixup_segment): 386 uses strange common symbol format.

11317 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
11319 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
11320 #elif, since it is not supported by old compilers.
11321 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
11322 couple of expressions in tc-m68k.c.
11324 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11326 * read.c (cons): If NO_RELOC is defined, use it.

11332 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
11333 local labels to start with a .) and set REGISTER_PREFIX to %.
11334 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
11336 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
11338 * messages.c: Comment changes.
11340 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

11343 * messages.c: If __STDC__ is not defined, define NO_STDARG.
11345 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
11347 * listing.c (debugging_pseudo): Add stabs and stabn as things to
11350 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
11352 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
11353 sections starting from zero, rather than making them consecutive.
11354 This makes subsequent reloc calculations easier, esp if the object
11355 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
11356 allocate lcomm in .data rather than in .bss. It seems that some
11357 tools can't cope with a non-zero sized bss before linkage.
11359 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11361 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
11362 throughout. That enum no longer means what we thought it meant.
11364 * tc-m68k.c (md_assemble, md_parse_option): Handle new
11365 "-mno-688[58]1" options.
11367 * tc-m68k.c: Added CPU32 support.
11369 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

11380 * Makefile.in (install): if $(tooldir) exists, install as in
11383 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
11385 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
11386 .word is < -32768 or > 32767. The -J flag causes the error to be
11387 ignored. This is to catch over-sized switches generated by gcc on
11388 systems which don't support the broken .word hack.
11389 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
11390 write.c (fixup_segment): check for signed .word overflow if
11391 WARN_SIGNED_OVERFLOW_WORD.
11393 * write.c (fixup_segment): fixed missing parens in expression
11394 checking for byte or word overflow.
11396 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
11397 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
11398 WARN_SIGNED_OVERFLOW_WORD.

11406 * obj-coffbfd.h : added stuff
11407 * tc-i386.c (tc_coff_fix2rtype): new function
11408 * tc-i386.h : new coff defines
11410 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
11412 * input-scrub.c (input_scrub_push): call input_file_begin, not
11414 messages.c (as_perror): print ": " between the passed in error and
11415 the strerror, like perror does.
11417 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

11424 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
11425 Motorola and MIT syntax; gas can now assemble either type of
11427 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
11428 From Steve Chamberlain:
11429 m68kcoff.mt: for m68k COFF.
11430 obj-coffbfd.c: (fixup_mdeps) added
11431 (size_section) removed bad sanity check
11432 (fill_section) added rs_machine_dependent case
11433 (write_object_file) call fixup_mdeps
11434 (fixup_segment) set fx_subsy to 0.
11435 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
11437 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
11440 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

11463 * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
11464 tc-i960.c (md_ri_to_chars): Always output bout object file in
11465 little endian byte order (used to use endianness of host).
11467 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11469 * config/tc-m68k.c (init_table): Now const. Always include 68851
11470 data, so that "bc" is available to 68040 cache instructions.
11471 Added "tt0", "tt1", and 68ec030 variants.
11472 (md_assemble): Complain if 68000 (only) and 68881 are specified.
11473 (enum _register): Added TT0, TT1.
11474 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
11475 line number correctly in "internal error" messages. Don't print
11476 architecture-mismatch message for operand errors.
11478 From Colin Smith (colin@wrs.com):
11479 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
11480 than install_operand.
11482 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)

11489 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
11491 * Makefile.in: defined TARGET_CPU for C code so that it can choose
11492 one element of a family.
11494 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
11496 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
11497 so that we can assemble hand-written libgcc code.
11499 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11501 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
11502 has already been formatted (but may still contain %-characters).
11503 (as_bad): Likewise.
11505 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
11507 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
11508 written with indirection on the last two operands, which can be
11509 either data or address registers. Added a new operand type 'r'
11510 which accepts either register type. Added '(' to notend stuff in
11511 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
11513 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
11515 * as.h (enum _relax_state): Start off at one, not zero, to better
11516 catch uninitialized-variable errors.
11517 (linkrelax): Declare new variable.
11519 * messages.c (warning_count, error_count): Default initializer is
11522 * write.c: Merged some declarations, using PARMS macro.

11524 data_last_frag): No longer static.
11525 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
11526 defined, call it. Change segments before calling fixup_segment.
11527 (relax_align): If linkrelax, provide extra padding.
11529 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
11530 their not having symbols associated.
11532 * tc-i960.c (norelax, instrument_branches): Default initializer is
11534 (linkrelax): Delete variable definition.

11555 Mon Aug 17 15:09:56 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11557 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
11558 being used with args swapped, causing occasional lossage when
11559 refilling buffers after an include file.
11561 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
11563 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
11564 version. Discard bogus DONTDEF version.
11565 (as_warn, as_bad, as_fatal): Likewise.
11567 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
11569 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
11570 selected architecture, print a message saying so and listing what
11571 processors support it, rather than saying "operands mismatch".
11573 Thu Aug 13 13:53:19 1992 Ken Raeburn (raeburn@cygnus.com)

11762 * Makefile.in (install): Install into $(tooldir)/bin, since that's
11763 where gcc looks for it.
11765 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
11767 * Makefile.in: Changed some lines to be less confusing for some

11807 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
11809 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

11833 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
11835 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
11837 * expr.c (operand): if can't work out what sort of operand it is,
11838 then look through FLT_CHARS for a hint.
11840 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
11842 * Makefile.in, configure.in: removed traces of namesubdir,
11843 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11844 copyrights to '92, changed some from Cygnus to FSF.
11846 * doc/Makefile.in, doc/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 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11852 * expr.c: If an expression is single comma, then return with
11853 SEG_ABSENT rather than an error - since the sparc front end does
11854 really strange things with things like fbge,a
11856 * as.h: include bfd.h if using many sections
11857 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
11858 local labels didn't work.
11859 * listing.c (list_symbol_table): don't core dump when there's no
11861 * write.c, write.h: call fix_new with the right number of args on
11863 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
11866 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11868 * app.c: MRI compatibility - allow single quote to start a string.
11869 * as.c: fix typo recently introduced.
11870 * as.h : Don't include aout/reloc.h - it's not right for COFF!
11871 * expr.c: Much rewriting, to accomodate MRI syntax for
11872 expressions. Also easier to read now.
11873 * listing.c: Put back defuns
11874 * read.c: modified to accept MRI syntax, put back listing pseudo
11875 ops so that an assembler built with NO_LISTING ignores list ops
11877 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
11878 machine is a SPARC or a 29K.
11879 * config/obj-aout.c: added s_sect pseudo op
11880 * config/obj-coffbfd.c: lints, set the filehdr flags right and
11881 fill in the timestamp.
11882 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
11883 anymore, define all the relocs which the tc-<x> bit will use so we
11884 can translate from them to the coff types.
11885 * config/tc-a29k.c: reloc_type isn't ane enum any more
11886 * config/tc-m68k.c: Added NO_RELOC definition.
11888 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
11890 * Makefile.in: put header files before C source for TAGS; remove
11891 references to non-existent syscalls.h.
11893 * read.c, write.c subsegs.c: back out the .bss changes.
11895 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
11897 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
11899 * a.out.h: removed.
11901 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
11903 * symbols.c (local_label_name): symbols now start with ^A.
11905 * read.c, subsegs.c, write.c obj-coff.c: added handling of
11906 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
11907 generate these sections. .align: will use NOP_OPCODE or 0
11908 for padding. This is just for being nice to the
11911 * expr.c (operand): changed to generate local label "\001L0"
11912 starting with a ^A so that it is recognized as a local label.
11914 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
11916 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
11917 i/o opcodes - inb, inw, outb and outw. string manipulation with
11918 att syntax - scmp, slod, smov, ssca, ssto.
11920 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
11921 to just after .file .
11923 In obj_crawl_symbol_chain() where it tries to put the external
11924 symbols apart, with the condition:
11925 (!S_IS_DEFINED(symbolP) &&
11926 !S_IS_DEBUG(symbolP) &&
11927 !SF_GET_STATICS(symbolP))
11928 it was moving too many symbols out. So I switch it back to the
11930 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
11932 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
11933 so that we don't use the F_RELFLG which make the linker complain
11934 that somebody has stripped the relocation info.
11936 Also, the AIX ld program require that the relocation table
11937 is sorted by r_vaddr like the standard ATT assembler does.
11939 [he also changed the sizeof(struct ...)'s into the coff
11940 style FOOSZ macros. I'm not sure this is right, but I can't
11941 remember why. xoxorich.]
11943 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
11945 * Makefile.in, configure.in, doc: use the doc. Build it, install
11948 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
11950 * read.c: white space and comments only.
11952 * configure.in: use the new atof-ns32.c for ns32k.
11954 * write.c: comment change only.
11956 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
11957 aren't yet integrated.
11959 * tc-i860.[hc]: blew off the dust. Something must still be done
11960 about conflicting relocation types.
11962 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
11965 * tc-i960.c, tc-sparc.c: white space and comments only.
11967 * tc-a29k.h: delete duplicate macro definition.
11969 * new file atof-ns32k.c copied from hack's last unreleased gas.
11971 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
11973 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
11976 * nearly everything. flush ChangeLog, package as gas-1.92.1.
11977 ChangeLog's prior to this are sketchy at best. I have logs.
11978 They just aren't ChangeLogs.
