3583 expression-valued symbol, and calling fix_new_exp recursively.
3584 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
3585 undefined symbol and a constant, fold the constant into the fixup,
3586 and refer to the undefined symbol directly. Then process the
3587 fixup again from scratch.

3730 (bitfield_suffix, setup_basic_type): new routines.
3731 (VMS_typedef_parse): use them. Now recognize bitfields of all
3732 integral types, not just type `int'. Caveat: the representation
3733 used for bitfields still does not work for objects placed in
3734 registers, and gcc's optimizer sometimes puts small structs there.
3736 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3738 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
3739 bit from const_flag.
3740 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
3741 (tc_frob_label): define this to call vms_check_for_special_label,
3742 and declare the latter.
3743 * config/obj-vms.c (vax_g_doubles): declare this file-scope
3745 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
3746 (vms_check_for_special_label): new routine (tc_frob_label).
3747 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
3748 and `gcc2_compiled.' labels; they won't reach here any more.
3749 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
3750 double', use `vax_g_doubles' flag to select type of double.
3751 (VMS_write_object_file) [traceback setup]: don't pass symbols
3752 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
3753 and TBT_Routine_End functions.

3757 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
3758 S_GET_VALUE() to avoid many repeated function calls.
3759 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
3760 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
3761 gets requested. [All the HACK_DEC_C_STARTUP code appears to
3762 be obsolete; gcc does it automatically for vms target. It's
3763 also misnamed, because it is for the "VAX C" run-time library,
3764 not the newer "DEC C" one which has much different startup code.]
3765 {various}: use `S_SET_xxx(symbol,new_value)' rather than
3766 `S_GET_xxx(symbol) = new_value'.
3768 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3770 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,

3775 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
3777 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
3779 * expr.c (expr): Don't reduce the difference of two symbols in the
3780 same frag if the symbols are not in normal sections.

3788 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
3789 fixups, store 32bits of unwind information in the fx_addnumber
3791 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
3792 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
3793 pointer to 32 bits of unwind info.
3794 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
3795 pointer to the dummy symbol; set the addend field to fx_addnumber.
3796 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
3797 rather than &bfd_XXX_section.
3799 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3801 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
3802 value by one; discard adjustments previously being made. From
3805 VMS- and Vax-related changes from Pat Rankin:
3806 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
3807 * vmsconf.sh: no longer have make-gas.com echo text about needing
3808 to modify the gcc-vms driver when intending to use with gcc 1.x.
3809 * as.c (parse_options): suppress 'v' from std_short_options and
3810 eliminate VMS-specific conditional initialization;
3811 [default case]: check for '-v' if md_parse_options doesn't recognize
3813 [default case, #if VMS]: check for filename argument when '-v' seen;
3815 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
3816 for O_big literal operands (double floats and long long ints);
3817 [VMS, md_shortopts]: add second colon after 'v';
3818 (md_parse_options) [VMS, case 'v']: check for argument, so
3819 caller can handle `-v' w/o arg.

3929 fixup is not local, to prevent relocations against externals from
3931 (md_assemble): Initialize disp_reloc field to NO_RELOC. Pass
3932 disp_reloc field to reloc() function, and use TC_RELOC to generate

3964 * ecoff.c (ecoff_build_symbols): If BSF_FUNCTION is set for an
3965 external symbol with no type, set the type to st_Proc rather than

4014 Update for autoconf beta 1.112:
4015 * aclocal.m4 (GAS_CHECK_DECL_NEEDED, GAS_WORKING_ASSERT): New
4017 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
4018 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
4019 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
4020 message to try to ease confusion about autoconf's
4021 "cross-compiling" message.
4022 * acconfig.h (NEED_DECLARATION_MALLOC, NEED_DECLARATION_FREE,
4023 NEED_DECLARATION_ERRNO): Renamed from NEED_*_DECLARATION.

4067 * Makefile.in (target_alias, program_transform_name): Define,
4068 using autoconf @-substitutions.

4165 INSTALL_DATA): Use autoconf @-substitutions.
4167 * input-file.c: Don't include assert.h here, 'cause as.h already

4769 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
4770 to put a common symbol in a set.

4815 * read.c (emit_expr): Use memset to zero out memory, rather than
4816 going through md_number_to_chars. This permits handling symbolic

4870 (control_regs): New pointer.
4871 (m68k_ip): Use control_regs instead of testing CPU every time.
4872 Use last_movec_reg too. In error messages, handle 68060, and
4873 print 68060 for mfloat, too.
4874 (m68k_init_after_args): Handle "68060". Use m68040up for making
4875 m68851 choice. Set control_regs.

5167 * config/obj-coffbfd.c (fill_section): Check COFF_NOLOAD_PROBLEM
5168 also before setting STYP_NOLOAD for .bss section.
5170 * config/tc-m68k.c (flag_reg_prefix_optional): New variable.
5171 Initialized to value of REGISTER_PREFIX_OPTIONAL, if defined, or

5244 * config/tc-mips.c (append_insn): Permit branches to be switched
5245 with the preceding instruction even if .set nobopt has been seen.
5246 .set nobopt actually controls whether to bring up an instruction

5312 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
5314 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
5316 * vmsconf.sh: In generated file, get ".obj" suffix right, build
5317 source files from other directories into objects in the current
5318 directory, and specify PSECT attributes explicitly to linker.
5319 Also added missing label.
5320 * Makefile.in (stamp-mk.com): Reference new variable

5387 elf_tc_make_sections stuff. It was there to support PA braindamage
5388 which has been fixed, and in the case of elf_tc_make_sections is
5389 redundant with elf_tc_final_processing.
5391 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

5409 don't spew remainder of input file in error message.
5410 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error

5414 targets, now explicitly checking $(srcdir) for info files.
5415 (install-info): Depend on both of them; do nothing more.

5471 to make it pcrel_offset.
5472 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to

5489 but it should eventually be converted to generate the insn itself
5490 and call emit_insn directly.

5492 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

5524 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
5525 -non_shared to use NO_PIC (this is how the Irix 5 assembler
5526 works). Do not permit -G with SVR4_PIC.
5527 (s_abicalls): Warn if -G was used, and force -G 0.
5528 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for

5578 bfd_set_symtab is called.
5579 (dump_section_relocs): Note whether a symbol is a section symbol
5581 (adjust_reloc_syms): For now, always supply an absolute symbol for
5582 fixups without symbols but not yet `done'. Use section_symbol to
5583 get the symbol, instead of going directly for abs_symbol.
5584 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
5585 reloc is not a section symbol and is not in the symbol table.
5586 (set_symtab): New function, broken out from write_object_file.
5587 Counts symbol table instead of relying on an earlier count.
5588 (write_object_file): Call set_symtab, but do it after potentially
5589 invoking the *_frob_file macros. Don't bother counting symbols.
5590 Call symbol_remove, instead of expanding it in place. Moved the
5591 conditionalized `object_file_size' declaration down to
5592 conditionalized block where it's used. When using the absolute
5593 symbol for a fixup without a symbol, set sy_used_in_reloc.
5594 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
5595 the correct symbol for the absolute section.
5597 * subsegs.c (section_symbol): Use symbol_new instead of
5598 symbol_make, since we may want it to go into the symbol table.
5599 Make the new symbol have internal linkage. If
5600 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
5601 symbol with the newly created GAS symbol.
5602 (obj_sec_sym_ok_for_reloc): Default to always returning 0.

5610 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
5611 (sparc_ip, label "immediate"): Reject constants for pcrel
5612 instructions only if the relocation type indicates a "call"
5613 instruction and the offset is within range of a "jmpl %g0". If
5614 it's not in range, use the absolute section symbol plus an offset.
5615 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
5617 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
5619 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
5622 * configure.in: Eliminated all targets using obj-coff but not
5623 defining BFD_ASSEMBLER; I think all such targets that are
5624 supported will be matched by real CPU-OS combinations earlier in
5626 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
5627 some comments about the dpx2 configuration, but left it disabled,
5628 since it couldn't be reached before.

5639 the 'j' operand if there are no further alternatives for this
5642 * config/obj-coffbfd.c (adjust_stab_section): Initialize
5643 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
5644 is not SEG_UNKNOWN rather than checking whether it is >= 0.
5646 * config/tc-mips.c (mips_align): Take new argument, label, and use
5647 it instead of global insn_label.
5648 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
5649 call to mips_emit_delay and pass it to mips_align.
5651 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5653 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.

5671 values to reduce number of lookups with S_GET_VALUE. Skip debug
5672 symbols to avoid "a really nasty bug". (From Holger Teutsch,
5673 holger@botbso.rhein-main.de.)
5674 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
5675 field. (Also from Holger Teutsch.) Watch for a would-be register
5676 mask that spans frags.
5678 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
5679 this_base, not line_base. (Patch from Andreas Arens,

5692 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

7477 pass new argument for i, j and o cases.
7478 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

7699 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
7700 the table, require that the one without bit 0x1000000 set come

7816 for keeping or rejecting configurations still under development;
7817 default is to assume production environment, and reject configs
7818 still being worked on. Mark Elf configurations (except sparc and
7819 i386) as developmental. Deleted cases matching some generic names
7820 in favor of more specific names. (E.g., when we get Alpha

7838 for functions only used within tc-hppa.c, likewise for structures,
7839 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
7840 conditional code in a few small places.
7842 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group

7846 into a few places. Make all functions and variables which
7847 are only used within tc-hppa.c static. PARAMize all functions.
7848 Add comments to functions. Delete unused functions, variables,
7849 #defines, etc. Delete unused members within structures. Delete
7850 ldil;ble hacks -- it is believed they were installed to work
7851 around old gas bugs. Avoid using mixed case for local
7852 functions, variables, and structures. Fix formatting problems
7853 not found by GNU-indent. Add FIXME notices for things which
7854 should be worked on the near future. Delete lots of old
7855 useless (1.36 PA-SOM) code.

7884 a multiple of the section alignment rather than always a
7887 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
7888 bits are zero (eg they specify no relocations), then do not even
7889 bother adding their entries to thesymextn section.

9017 * Extensive changes to permit symbols to contain any expression
9018 type and to delay the computation of the expression until the
9019 value is actually needed. This permits setting symbols to values
9020 calculated based on object code size. Expressions were changed to
9021 no longer be in a section, to stop the overloading of segment and
9022 expression type that previously occurred.
9024 * as.c (big_section, pass1_section, diff_section, absent_section):
9026 (expr_section): Added (used for dummy symbols which hold

9135 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
9136 calculating opP->isiz; this permits the expression size to be
9137 determined as well, later on.

9151 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
9153 * read.c (float_cons): Simplified parsing logic. If
9154 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.

9202 (omagic): Removed unused variable.
9204 * Preliminary support for m88k-coff.

10261 than ECOFF line number information.
10262 (obj_ecoff_stab): Accept non-zero values for stabs line number.

10319 Mon Mar 29 12:56:56 1993 Ian Lance Taylor (ian@cygnus.com)
10321 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
10322 the bottom (make expands variables in dependencies when the
10323 dependencies are read, not when they are used).
10325 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
10326 a29k .bss section; the mondfe program doesn't like it.

10341 (srcdir): Delete second, bogus definition.
10342 (as.info): Look for as-*.texinfo in current directory rather than
10346 * doc/configure.in: Create links to all as-*.texinfo files in the
10347 source directory, if that's not the current directory.
10349 * configure.in (per-host): Accept MIPS host with BSD version
10351 (per-target): Classify i486 as i386. Use generic cpu_type instead
10352 of target_cpu in selecting format etc.

10370 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
10371 process relocs if there aren't any relocs to process. Avoids
10372 malloc/free bug on SCO too.
10374 * as.h: Move local include files below system include files, to
10375 avoid some redefinition complaints on some systems.
10376 (const, volatile): Don't need these conditionally defined if we
10377 use CONST and VOLATILE from ansidecl.h.
10378 (seg_name): Use CONST, not const.
10380 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
10382 * config/tc-mips.c: Reindented to GNU standards.

10386 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
10387 (fixup_segment): Add a29k special case; the linker is not prepared
10388 to see a segment offset here.
10390 * app.c (do_scrub_next_char): Added new state, 10, modifying state
10391 9 to only keep a space in between identifier characters.
10393 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
10395 * Makefile.in: add dvi target; as-$(config).texinfo might live in
10396 srcdir, might be in objdir.
10398 * doc/Makefile.in: dvi depends on as.dvi

10421 * Makefile.in (targ-cpu.o): Depend on config.h.
10423 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
10425 * app.c (do_scrub_next_char): Added new state, 9, to avoid
10426 dropping a space immediately following an identifier.
10427 * expr.c, write.c: Rewrote assert expressions to not use multiple
10428 lines; I don't think that can be done portably.
10429 * config/tc-mips.c (macro): Use $AT if target register is zero in
10430 load instruction, which it can be for a floating point load.
10432 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)
10434 * write.c (write_contents): Compute the relocs before writing out
10435 the section contents.
10436 * config/obj-ecoff.h, config/obj-ecoff.c: Numerous changes to get
10437 symbol table and values right.
10438 * config/tc-mips.h (LOCAL_LABEL): If OBJ_ECOFF, any label starting
10440 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
10441 by the section vma.
10443 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
10444 z8k-opc.h, not z8k.h.
10446 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
10449 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

10500 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
10501 (struct loc, struct proc, struct file): Moved to tc-mips.c within
10502 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
10503 * config/tc-mips.c: Rearranged for ECOFF support. Added
10504 prototypes for all static functions. Moved existing minimal
10505 debugging format support info #ifndef OBJ_ECOFF blocks.
10506 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
10507 does not support a non sign extended high 16 bits reloc. Adjusted
10508 all callers accordingly.

10554 * make-gas.com: Find obstack.obj if it's not in the current
10556 * read.c (s_ignore): Don't declare is_end_of_line. It's
10557 redundant, and triggers a VMS gcc compiler bug.
10559 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
10560 current segment as an argument. (Ignored in all cases but VMS.)
10561 All callers and definitions changed.
10563 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
10565 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING
10566 case compile again.

10579 argument to s_ignore. Put "#if 0" around unused code.
10580 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
10581 Call elf_xstabs for .stabs and .xstabs operators.
10583 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
10585 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
10588 * configure.in: mips-bsd configuration was missing format spec.
10591 * Makefile.in (Makefile): Depends on configure.in.
10593 * config/tc-mips.c (append_insn): Don't check for alignment of
10594 frag in memory; alignment of instructions in section is a separate

10614 * config/tc-sparc.c (s_xword): Now call big_cons, so large
10615 constants are accepted, but symbolic values are not. GCC will not
10616 generate the latter currently.
10618 * frags.c (frag_init): New function.
10619 (zero_address_frag, bss_address_frag): Now initialized at run

10649 (S_SET_TYPE) [!BFD_ASSEMBLER]: New macro.
10650 * config/obj-aout.c: Use PARAMS macro for declarations. Remove
10651 "IGNORE_DEBUG" conditional, since both branches are identical.
10652 Use S_SET_TYPE, S_GET_TYPE, and S_GET_DESC instead of directly
10653 referencing symbol structure members.
10654 (obj_aout_frob_symbol) [BFD_ASSEMBLER]: New function.
10656 * as.h (struct frag): Reordered a couple of fields for better

10662 (write_object_file) [BFD_ASSEMBLER]: Always handle -R here. Call
10663 fix_new with BFD_RELOC_NONE instead of 0 or NO_RELOC. Call
10664 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.

10891 (operand): Set X_add_number field for floating-point numbers.
10892 (operand): Treat zero byte as end-of-operand.
10894 * configure.in (per-target): Look for with_bfd_assembler option.
10895 For now, only accept "no", until the merge is done.
10897 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
10898 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
10899 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
10900 * read.c: Finish conversion to S_* macros in the VMS only

10909 * write.c: Add "const" modifier to md_[long,short]_jump_size.
10910 Fix arguments to VMS_write_object_file.
10911 * config-gas.com: New file. Script for VMS systems to set up the
10912 configuration to build gas for VMS, and create config.status.

10920 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
10921 types of malformed stabs. Change parsing algorithm so that we are
10922 more certain of having all of the information that we need on hand.
10923 * obj-vms.c (final_forward_reference): New function, used to help
10924 resolve the data types of as many struct elements as possible

10926 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
10928 * obj-vms.c (VMS_write_object_file): Define all vtable psects
10929 as symbols as well in the object file. Look for external functions

10973 if these are used or defined, if BFD_ASSEMBLER.
10974 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
10975 subseg_new split into two functions.
10976 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.

11014 (size_section): Restored sanity check.
11015 (do_relocs_for): Base section address on s_paddr rather than
11016 computing it. Adjust a29k R_IHIHALF special case to account for
11017 section paddr (used to require paddr to be zero). If there are no
11018 reclos, set s_relptr to 0. Set relocation size in object_headers.
11019 (fill_section): Always set s_vaddr here, removing
11020 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
11021 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
11022 Set STYP_INFO for .comment.
11023 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
11024 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

11029 set s_vaddr here. If string_byte_count remains 4, set it back to
11030 0, and only write strings out if there are some. Call
11031 fill_section before do_relocs_for and do_linenos_for.
11032 (obj_coff_section): Handle optional quoted second argument giving
11033 section characteristics.
11034 (obj_coff_bss): Added to handle .bss.

11056 (symbol_chars): Now const.
11058 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
11059 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
11061 * config/obj-coff.h: Don't use #elif.
11063 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
11064 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
11066 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
11068 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

11090 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
11091 using ZERO_BASED_SEGMENTS.
11092 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
11093 never set segment address for SEG_E2 (.bss) and don't write out
11094 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
11095 (obj_coff_endef): Don't merge labels or symbols awaiting forward
11096 definitions, and don't merge tags with non-tags. Check for .bf
11097 rather than just checking whether the second character is b and
11098 the third character is f.
11099 (obj_coff_val): gcc can generate values which we don't handle
11100 correctly; discard information for now, since it only affects the
11101 debugging information.

11103 (yank_symbols): Don't merge labels.
11104 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
11105 already defined. Fill subsegments with NOP_OPCODE, not 0. Don't
11106 set segment address if ZERO_BASED_SEGMENTS.
11107 (obj_coff_section): Accept and ignore a trailing quoted string, as
11108 used in AT&T i386 syntax.
11109 (fixup_segment): Take segment as argument. On the i386, adjust PC
11110 relative addends by the segment vaddr.

11254 z8000 documentation
11255 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
11258 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
11260 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
11262 * subsegs.h: add extern to segment_info declaration.
11264 * read.h: added extern declarations for comment_chars,
11265 line_comment_chars, and line_separator_chars.
11266 read.c, app.c: removed definitions of comment_chars,
11267 line_comment_chars, and line_separator_chars.
11269 * tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
11270 still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
11272 (insert_reg): put REGISTER_PREFIX before register names before

11284 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11286 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
11287 constant will not fit in an immediate field.
11288 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
11290 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
11292 * obj-coff.c (callj_table): Delete global variable.
11293 (obj_emit_relocations): Define it locally here, and only if
11294 TC_I960 is defined.
11296 * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.
11297 (m68k_ip): Don't warn about bignum used as float bit-pattern.

11305 * tc-i960.c: Missed a couple of 0->NO_RELOC conversions.
11307 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
11308 so widening works consistently.
11310 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)

11323 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
11325 * Support for i386-sysv.
11326 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
11327 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
11328 be used to set them all to zero as was done before.
11329 (fill_section): segment addresses now set in write_object_file.
11330 (fill_section): Don't set STYP_NOLOAD for .bss section.
11331 (fixup_segment): 386 uses strange common symbol format.
11332 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
11333 compatibility with SVR3.2 linker.

11364 * tc-z8k.c: lots of bug fixes
11366 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
11368 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
11369 #elif, since it is not supported by old compilers.
11370 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
11371 couple of expressions in tc-m68k.c.
11373 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11375 * read.c (cons): If NO_RELOC is defined, use it.
11377 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
11379 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
11381 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
11382 local labels to start with a .) and set REGISTER_PREFIX to %.
11383 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
11385 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
11387 * messages.c: Comment changes.
11389 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
11391 * as.h: Test if __STDC__ is defined only, don't test its value.
11392 * messages.c: If __STDC__ is not defined, define NO_STDARG.
11394 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
11396 * listing.c (debugging_pseudo): Add stabs and stabn as things to
11399 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
11401 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
11402 sections starting from zero, rather than making them consecutive.
11403 This makes subsequent reloc calculations easier, esp if the object
11404 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
11405 allocate lcomm in .data rather than in .bss. It seems that some
11406 tools can't cope with a non-zero sized bss before linkage.
11408 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11410 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
11411 throughout. That enum no longer means what we thought it meant.
11413 * tc-m68k.c (md_assemble, md_parse_option): Handle new
11414 "-mno-688[58]1" options.
11416 * tc-m68k.c: Added CPU32 support.
11418 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11420 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.

11429 * Makefile.in (install): if $(tooldir) exists, install as in
11432 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
11434 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
11435 .word is < -32768 or > 32767. The -J flag causes the error to be
11436 ignored. This is to catch over-sized switches generated by gcc on
11437 systems which don't support the broken .word hack.
11438 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
11439 write.c (fixup_segment): check for signed .word overflow if
11440 WARN_SIGNED_OVERFLOW_WORD.
11442 * write.c (fixup_segment): fixed missing parens in expression
11443 checking for byte or word overflow.
11445 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
11446 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
11447 WARN_SIGNED_OVERFLOW_WORD.
11449 * obj-coffbfd.c (fixup_segment): fixed missing parens in
11450 expression checking for byte or word overflow.
11452 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11454 Support for i386 coff
11455 * obj-coffbfd.h : added stuff
11456 * tc-i386.c (tc_coff_fix2rtype): new function
11457 * tc-i386.h : new coff defines
11459 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
11461 * input-scrub.c (input_scrub_push): call input_file_begin, not
11463 messages.c (as_perror): print ": " between the passed in error and
11464 the strerror, like perror does.
11466 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
11468 * Makefile.in: use gas_target instead of modifying target_cpu.
11469 From Steve Chamberlain:
11470 Makefile.in: Handle m68*-*-coff*.
11471 read.c, read.h: add mult argument to s_space
11473 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
11474 Motorola and MIT syntax; gas can now assemble either type of
11476 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
11477 From Steve Chamberlain:
11478 m68kcoff.mt: for m68k COFF.
11479 obj-coffbfd.c: (fixup_mdeps) added
11480 (size_section) removed bad sanity check
11481 (fill_section) added rs_machine_dependent case
11482 (write_object_file) call fixup_mdeps
11483 (fixup_segment) set fx_subsy to 0.
11484 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
11486 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
11489 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11491 * Makefile.in (LIBS): Include opcode library.
11493 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
11495 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
11496 including zero are accepted, pass +0.0.
11498 Sun Aug 30 21:24:46 1992 Ian Lance Taylor (ian@cygnus.com)
11500 * Makefile.in: map "as" through program_transform_name when
11503 * doc/Makefile.in: map "as" through program_transform_name when
11506 Sat Aug 29 12:11:12 1992 Jim Wilson (wilson@sphagnum.cygnus.com)

11512 * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
11513 tc-i960.c (md_ri_to_chars): Always output bout object file in
11514 little endian byte order (used to use endianness of host).
11516 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11518 * config/tc-m68k.c (init_table): Now const. Always include 68851
11519 data, so that "bc" is available to 68040 cache instructions.
11520 Added "tt0", "tt1", and 68ec030 variants.
11521 (md_assemble): Complain if 68000 (only) and 68881 are specified.
11522 (enum _register): Added TT0, TT1.
11523 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
11524 line number correctly in "internal error" messages. Don't print
11525 architecture-mismatch message for operand errors.
11527 From Colin Smith (colin@wrs.com):
11528 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
11529 than install_operand.
11531 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11533 * listing.c (buffer_line): rewind to the start of include
11534 files, they might be included twice.
11536 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
11538 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
11540 * Makefile.in: defined TARGET_CPU for C code so that it can choose
11541 one element of a family.
11543 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
11545 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
11546 so that we can assemble hand-written libgcc code.
11548 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11550 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
11551 has already been formatted (but may still contain %-characters).
11552 (as_bad): Likewise.
11554 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
11556 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
11557 written with indirection on the last two operands, which can be
11558 either data or address registers. Added a new operand type 'r'
11559 which accepts either register type. Added '(' to notend stuff in
11560 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
11562 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
11564 * as.h (enum _relax_state): Start off at one, not zero, to better
11565 catch uninitialized-variable errors.
11566 (linkrelax): Declare new variable.

11811 * Makefile.in (install): Install into $(tooldir)/bin, since that's

11891 * Makefile.in, configure.in: removed traces of namesubdir,
11892 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced

11895 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
11896 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11897 copyrights to '92, changed some from Cygnus to FSF.
11899 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11901 * expr.c: If an expression is single comma, then return with
11902 SEG_ABSENT rather than an error - since the sparc front end does
11903 really strange things with things like fbge,a
11905 * as.h: include bfd.h if using many sections
11906 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
11907 local labels didn't work.
11908 * listing.c (list_symbol_table): don't core dump when there's no
11910 * write.c, write.h: call fix_new with the right number of args on
11912 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
11915 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11917 * app.c: MRI compatibility - allow single quote to start a string.
11918 * as.c: fix typo recently introduced.
11919 * as.h : Don't include aout/reloc.h - it's not right for COFF!
11920 * expr.c: Much rewriting, to accomodate MRI syntax for
11921 expressions. Also easier to read now.
11922 * listing.c: Put back defuns
11923 * read.c: modified to accept MRI syntax, put back listing pseudo
11924 ops so that an assembler built with NO_LISTING ignores list ops
11926 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
11927 machine is a SPARC or a 29K.
11928 * config/obj-aout.c: added s_sect pseudo op
11929 * config/obj-coffbfd.c: lints, set the filehdr flags right and
11930 fill in the timestamp.
11931 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
11932 anymore, define all the relocs which the tc-<x> bit will use so we
11933 can translate from them to the coff types.
11934 * config/tc-a29k.c: reloc_type isn't ane enum any more
11935 * config/tc-m68k.c: Added NO_RELOC definition.
11937 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
11939 * Makefile.in: put header files before C source for TAGS; remove
11940 references to non-existent syscalls.h.
11942 * read.c, write.c subsegs.c: back out the .bss changes.
11944 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
11946 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
11948 * a.out.h: removed.
11950 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
11952 * symbols.c (local_label_name): symbols now start with ^A.
11954 * read.c, subsegs.c, write.c obj-coff.c: added handling of
11955 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
11956 generate these sections. .align: will use NOP_OPCODE or 0
11957 for padding. This is just for being nice to the
11960 * expr.c (operand): changed to generate local label "\001L0"
11961 starting with a ^A so that it is recognized as a local label.
11963 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
11965 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
11966 i/o opcodes - inb, inw, outb and outw. string manipulation with
11967 att syntax - scmp, slod, smov, ssca, ssto.
11969 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
11970 to just after .file .
11972 In obj_crawl_symbol_chain() where it tries to put the external
11973 symbols apart, with the condition:
11974 (!S_IS_DEFINED(symbolP) &&
11975 !S_IS_DEBUG(symbolP) &&
11976 !SF_GET_STATICS(symbolP))
11977 it was moving too many symbols out. So I switch it back to the
11979 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
11981 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
11982 so that we don't use the F_RELFLG which make the linker complain
11983 that somebody has stripped the relocation info.
11985 Also, the AIX ld program require that the relocation table
11986 is sorted by r_vaddr like the standard ATT assembler does.
11988 [he also changed the sizeof(struct ...)'s into the coff
11989 style FOOSZ macros. I'm not sure this is right, but I can't
11990 remember why. xoxorich.]
11992 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
11994 * Makefile.in, configure.in, doc: use the doc. Build it, install

11999 * read.c: white space and comments only.
12001 * configure.in: use the new atof-ns32.c for ns32k.
12003 * write.c: comment change only.
12005 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
12006 aren't yet integrated.
12008 * tc-i860.[hc]: blew off the dust. Something must still be done
12009 about conflicting relocation types.
12011 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
12014 * tc-i960.c, tc-sparc.c: white space and comments only.
12016 * tc-a29k.h: delete duplicate macro definition.
12018 * new file atof-ns32k.c copied from hack's last unreleased gas.
12020 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
12022 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
12025 * nearly everything. flush ChangeLog, package as gas-1.92.1.
12026 ChangeLog's prior to this are sketchy at best. I have logs.
12027 They just aren't ChangeLogs.
