3595 expression-valued symbol, and calling fix_new_exp recursively.
3596 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
3597 undefined symbol and a constant, fold the constant into the fixup,
3598 and refer to the undefined symbol directly. Then process the
3599 fixup again from scratch.

3737 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
3738 many others): new macros; values obtained from "DSTRECRDS.SDL".
3739 * config/obj-vms.h (various): use them.
3740 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
3741 representation (only enum bitfields can avoid being bitstrings).
3742 (bitfield_suffix, setup_basic_type): new routines.
3743 (VMS_typedef_parse): use them. Now recognize bitfields of all
3744 integral types, not just type `int'. Caveat: the representation
3745 used for bitfields still does not work for objects placed in
3746 registers, and gcc's optimizer sometimes puts small structs there.
3748 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3750 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
3751 bit from const_flag.
3752 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
3753 (tc_frob_label): define this to call vms_check_for_special_label,
3754 and declare the latter.
3755 * config/obj-vms.c (vax_g_doubles): declare this file-scope
3757 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
3758 (vms_check_for_special_label): new routine (tc_frob_label).
3759 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
3760 and `gcc2_compiled.' labels; they won't reach here any more.
3761 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
3762 double', use `vax_g_doubles' flag to select type of double.
3763 (VMS_write_object_file) [traceback setup]: don't pass symbols
3764 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
3765 and TBT_Routine_End functions.

3769 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
3770 S_GET_VALUE() to avoid many repeated function calls.
3771 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
3772 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
3773 gets requested. [All the HACK_DEC_C_STARTUP code appears to
3774 be obsolete; gcc does it automatically for vms target. It's
3775 also misnamed, because it is for the "VAX C" run-time library,
3776 not the newer "DEC C" one which has much different startup code.]
3777 {various}: use `S_SET_xxx(symbol,new_value)' rather than
3778 `S_GET_xxx(symbol) = new_value'.
3780 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3782 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
3783 not &bfd_abs_section.
3785 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3787 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
3789 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
3791 * expr.c (expr): Don't reduce the difference of two symbols in the
3792 same frag if the symbols are not in normal sections.

3799 (fix_new_hppa): Last arg is now a pointer to an int. Do not
3800 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
3801 fixups, store 32bits of unwind information in the fx_addnumber
3803 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
3804 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
3805 pointer to 32 bits of unwind info.
3806 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
3807 pointer to the dummy symbol; set the addend field to fx_addnumber.
3808 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
3809 rather than &bfd_XXX_section.
3811 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3813 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
3814 value by one; discard adjustments previously being made. From
3817 VMS- and Vax-related changes from Pat Rankin:
3818 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
3819 * vmsconf.sh: no longer have make-gas.com echo text about needing
3820 to modify the gcc-vms driver when intending to use with gcc 1.x.
3821 * as.c (parse_options): suppress 'v' from std_short_options and
3822 eliminate VMS-specific conditional initialization;
3823 [default case]: check for '-v' if md_parse_options doesn't recognize
3825 [default case, #if VMS]: check for filename argument when '-v' seen;
3827 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
3828 for O_big literal operands (double floats and long long ints);
3829 [VMS, md_shortopts]: add second colon after 'v';
3830 (md_parse_options) [VMS, case 'v']: check for argument, so
3831 caller can handle `-v' w/o arg.

3889 to ensure that older versions of autoconf aren't used.
3890 * Makefile.in: Added @configure_input@ line.
3891 (configure): Deleted rule.

3941 fixup is not local, to prevent relocations against externals from
3943 (md_assemble): Initialize disp_reloc field to NO_RELOC. Pass
3944 disp_reloc field to reloc() function, and use TC_RELOC to generate

3976 * ecoff.c (ecoff_build_symbols): If BSF_FUNCTION is set for an
3977 external symbol with no type, set the type to st_Proc rather than

4026 Update for autoconf beta 1.112:
4027 * aclocal.m4 (GAS_CHECK_DECL_NEEDED, GAS_WORKING_ASSERT): New
4029 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
4030 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
4031 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
4032 message to try to ease confusion about autoconf's
4033 "cross-compiling" message.
4034 * acconfig.h (NEED_DECLARATION_MALLOC, NEED_DECLARATION_FREE,
4035 NEED_DECLARATION_ERRNO): Renamed from NEED_*_DECLARATION.

4079 * Makefile.in (target_alias, program_transform_name): Define,
4080 using autoconf @-substitutions.

4089 autoconf 1.109 has this fixed.
4090 * configure.in: Don't change quote characters around AC_MSG_ERROR
4091 invocation. Don't use AC_HEADER_STDC, since it requires running a

4882 (control_regs): New pointer.
4883 (m68k_ip): Use control_regs instead of testing CPU every time.

5399 elf_tc_make_sections stuff. It was there to support PA braindamage
5400 which has been fixed, and in the case of elf_tc_make_sections is
5401 redundant with elf_tc_final_processing.

5501 but it should eventually be converted to generate the insn itself
5502 and call emit_insn directly.

5504 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

5536 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
5537 -non_shared to use NO_PIC (this is how the Irix 5 assembler
5538 works). Do not permit -G with SVR4_PIC.
5539 (s_abicalls): Warn if -G was used, and force -G 0.
5540 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for

5590 bfd_set_symtab is called.
5591 (dump_section_relocs): Note whether a symbol is a section symbol
5593 (adjust_reloc_syms): For now, always supply an absolute symbol for
5594 fixups without symbols but not yet `done'. Use section_symbol to
5595 get the symbol, instead of going directly for abs_symbol.
5596 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
5597 reloc is not a section symbol and is not in the symbol table.
5598 (set_symtab): New function, broken out from write_object_file.
5599 Counts symbol table instead of relying on an earlier count.
5600 (write_object_file): Call set_symtab, but do it after potentially
5601 invoking the *_frob_file macros. Don't bother counting symbols.
5602 Call symbol_remove, instead of expanding it in place. Moved the
5603 conditionalized `object_file_size' declaration down to
5604 conditionalized block where it's used. When using the absolute
5605 symbol for a fixup without a symbol, set sy_used_in_reloc.
5606 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
5607 the correct symbol for the absolute section.
5609 * subsegs.c (section_symbol): Use symbol_new instead of
5610 symbol_make, since we may want it to go into the symbol table.
5611 Make the new symbol have internal linkage. If
5612 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
5613 symbol with the newly created GAS symbol.
5614 (obj_sec_sym_ok_for_reloc): Default to always returning 0.

5622 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
5623 (sparc_ip, label "immediate"): Reject constants for pcrel
5624 instructions only if the relocation type indicates a "call"
5625 instruction and the offset is within range of a "jmpl %g0". If
5626 it's not in range, use the absolute section symbol plus an offset.
5627 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
5629 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
5631 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
5634 * configure.in: Eliminated all targets using obj-coff but not
5635 defining BFD_ASSEMBLER; I think all such targets that are
5636 supported will be matched by real CPU-OS combinations earlier in
5638 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
5639 some comments about the dpx2 configuration, but left it disabled,
5640 since it couldn't be reached before.

5651 the 'j' operand if there are no further alternatives for this
5654 * config/obj-coffbfd.c (adjust_stab_section): Initialize
5655 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
5656 is not SEG_UNKNOWN rather than checking whether it is >= 0.
5658 * config/tc-mips.c (mips_align): Take new argument, label, and use
5659 it instead of global insn_label.
5660 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
5661 call to mips_emit_delay and pass it to mips_align.
5663 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5665 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.

5683 values to reduce number of lookups with S_GET_VALUE. Skip debug
5684 symbols to avoid "a really nasty bug". (From Holger Teutsch,
5685 holger@botbso.rhein-main.de.)
5686 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
5687 field. (Also from Holger Teutsch.) Watch for a would-be register
5688 mask that spans frags.
5690 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
5691 this_base, not line_base. (Patch from Andreas Arens,

5702 (lex_type): Use it for `%'.
5704 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

7437 descriptor information to the BFD symbol.
7438 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

7442 (pa_entry): Build a R_HPPA_ENTRY relocation when configured for SOM.
7443 (pa_exit): Likewise, but built a R_HPPA_EXIT relocation. Do not

7457 an example of marker relocations.
7458 * write.c (write_relocs): Instead of assuming size of a relocation
7459 is 4 bytes, pick up the size from relocation itself.

7489 pass new argument for i, j and o cases.
7490 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

7711 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
7712 the table, require that the one without bit 0x1000000 set come

7828 for keeping or rejecting configurations still under development;
7829 default is to assume production environment, and reject configs
7830 still being worked on. Mark Elf configurations (except sparc and
7831 i386) as developmental. Deleted cases matching some generic names
7832 in favor of more specific names. (E.g., when we get Alpha
7833 support, we'll still only support VMS for Vax.)

7849 through inclusion of tc-hppa.h. Delete all forward declarations
7850 for functions only used within tc-hppa.c, likewise for structures,
7851 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
7852 conditional code in a few small places.
7854 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
7855 structures, global variables, forward declarations together.

7857 conditional code -- try to group conditional code together
7858 into a few places. Make all functions and variables which
7859 are only used within tc-hppa.c static. PARAMize all functions.
7860 Add comments to functions. Delete unused functions, variables,
7861 #defines, etc. Delete unused members within structures. Delete
7862 ldil;ble hacks -- it is believed they were installed to work
7863 around old gas bugs. Avoid using mixed case for local
7864 functions, variables, and structures. Fix formatting problems
7865 not found by GNU-indent. Add FIXME notices for things which
7866 should be worked on the near future. Delete lots of old
7867 useless (1.36 PA-SOM) code.

9029 * Extensive changes to permit symbols to contain any expression
9030 type and to delay the computation of the expression until the
9031 value is actually needed. This permits setting symbols to values
9032 calculated based on object code size. Expressions were changed to
9033 no longer be in a section, to stop the overloading of segment and
9034 expression type that previously occurred.
9036 * as.c (big_section, pass1_section, diff_section, absent_section):
9038 (expr_section): Added (used for dummy symbols which hold

9163 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
9165 * read.c (float_cons): Simplified parsing logic. If
9166 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.

10273 than ECOFF line number information.
10274 (obj_ecoff_stab): Accept non-zero values for stabs line number.

10331 Mon Mar 29 12:56:56 1993 Ian Lance Taylor (ian@cygnus.com)
10333 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
10334 the bottom (make expands variables in dependencies when the
10335 dependencies are read, not when they are used).
10337 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
10338 a29k .bss section; the mondfe program doesn't like it.

10353 (srcdir): Delete second, bogus definition.
10354 (as.info): Look for as-*.texinfo in current directory rather than
10358 * doc/configure.in: Create links to all as-*.texinfo files in the
10359 source directory, if that's not the current directory.
10361 * configure.in (per-host): Accept MIPS host with BSD version
10363 (per-target): Classify i486 as i386. Use generic cpu_type instead

10383 process relocs if there aren't any relocs to process. Avoids
10384 malloc/free bug on SCO too.
10386 * as.h: Move local include files below system include files, to
10387 avoid some redefinition complaints on some systems.
10388 (const, volatile): Don't need these conditionally defined if we
10389 use CONST and VOLATILE from ansidecl.h.
10390 (seg_name): Use CONST, not const.
10392 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
10394 * config/tc-mips.c: Reindented to GNU standards.

10398 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
10399 (fixup_segment): Add a29k special case; the linker is not prepared
10400 to see a segment offset here.
10402 * app.c (do_scrub_next_char): Added new state, 10, modifying state
10403 9 to only keep a space in between identifier characters.
10405 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
10407 * Makefile.in: add dvi target; as-$(config).texinfo might live in
10408 srcdir, might be in objdir.
10410 * doc/Makefile.in: dvi depends on as.dvi

10435 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
10437 * app.c (do_scrub_next_char): Added new state, 9, to avoid
10438 dropping a space immediately following an identifier.
10439 * expr.c, write.c: Rewrote assert expressions to not use multiple
10440 lines; I don't think that can be done portably.
10441 * config/tc-mips.c (macro): Use $AT if target register is zero in
10442 load instruction, which it can be for a floating point load.
10444 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)
10446 * write.c (write_contents): Compute the relocs before writing out
10447 the section contents.
10448 * config/obj-ecoff.h, config/obj-ecoff.c: Numerous changes to get
10449 symbol table and values right.
10450 * config/tc-mips.h (LOCAL_LABEL): If OBJ_ECOFF, any label starting
10452 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
10453 by the section vma.
10455 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
10456 z8k-opc.h, not z8k.h.
10458 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
10461 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

10512 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
10513 (struct loc, struct proc, struct file): Moved to tc-mips.c within
10514 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
10515 * config/tc-mips.c: Rearranged for ECOFF support. Added
10516 prototypes for all static functions. Moved existing minimal
10517 debugging format support info #ifndef OBJ_ECOFF blocks.
10518 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
10519 does not support a non sign extended high 16 bits reloc. Adjusted

10566 * make-gas.com: Find obstack.obj if it's not in the current
10568 * read.c (s_ignore): Don't declare is_end_of_line. It's
10569 redundant, and triggers a VMS gcc compiler bug.
10571 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
10572 current segment as an argument. (Ignored in all cases but VMS.)
10573 All callers and definitions changed.
10575 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
10577 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING
10578 case compile again.

10582 * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,

10591 argument to s_ignore. Put "#if 0" around unused code.
10592 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
10593 Call elf_xstabs for .stabs and .xstabs operators.
10595 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
10597 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
10600 * configure.in: mips-bsd configuration was missing format spec.
10603 * Makefile.in (Makefile): Depends on configure.in.
10605 * config/tc-mips.c (append_insn): Don't check for alignment of
10606 frag in memory; alignment of instructions in section is a separate

10626 * config/tc-sparc.c (s_xword): Now call big_cons, so large
10627 constants are accepted, but symbolic values are not. GCC will not
10628 generate the latter currently.
10630 * frags.c (frag_init): New function.
10631 (zero_address_frag, bss_address_frag): Now initialized at run
10633 * as.c (main): Call frag_init.

10662 * config/obj-aout.c: Use PARAMS macro for declarations. Remove
10663 "IGNORE_DEBUG" conditional, since both branches are identical.
10664 Use S_SET_TYPE, S_GET_TYPE, and S_GET_DESC instead of directly
10665 referencing symbol structure members.
10666 (obj_aout_frob_symbol) [BFD_ASSEMBLER]: New function.
10668 * as.h (struct frag): Reordered a couple of fields for better

10903 (operand): Set X_add_number field for floating-point numbers.
10904 (operand): Treat zero byte as end-of-operand.
10906 * configure.in (per-target): Look for with_bfd_assembler option.
10907 For now, only accept "no", until the merge is done.
10909 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
10910 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
10911 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
10912 * read.c: Finish conversion to S_* macros in the VMS only

10921 * write.c: Add "const" modifier to md_[long,short]_jump_size.
10922 Fix arguments to VMS_write_object_file.
10923 * config-gas.com: New file. Script for VMS systems to set up the
10924 configuration to build gas for VMS, and create config.status.

10932 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
10933 types of malformed stabs. Change parsing algorithm so that we are
10934 more certain of having all of the information that we need on hand.
10935 * obj-vms.c (final_forward_reference): New function, used to help
10936 resolve the data types of as many struct elements as possible

10938 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
10940 * obj-vms.c (VMS_write_object_file): Define all vtable psects
10941 as symbols as well in the object file. Look for external functions

10985 if these are used or defined, if BFD_ASSEMBLER.
10986 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
10987 subseg_new split into two functions.
10988 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.

11026 (size_section): Restored sanity check.
11027 (do_relocs_for): Base section address on s_paddr rather than
11028 computing it. Adjust a29k R_IHIHALF special case to account for
11029 section paddr (used to require paddr to be zero). If there are no
11030 reclos, set s_relptr to 0. Set relocation size in object_headers.
11031 (fill_section): Always set s_vaddr here, removing
11032 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
11033 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
11034 Set STYP_INFO for .comment.
11035 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
11036 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

11041 set s_vaddr here. If string_byte_count remains 4, set it back to
11042 0, and only write strings out if there are some. Call
11043 fill_section before do_relocs_for and do_linenos_for.
11044 (obj_coff_section): Handle optional quoted second argument giving
11045 section characteristics.
11046 (obj_coff_bss): Added to handle .bss.

11068 (symbol_chars): Now const.
11070 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
11071 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
11073 * config/obj-coff.h: Don't use #elif.
11075 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
11076 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
11078 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
11080 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

11104 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
11105 never set segment address for SEG_E2 (.bss) and don't write out
11106 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
11107 (obj_coff_endef): Don't merge labels or symbols awaiting forward
11108 definitions, and don't merge tags with non-tags. Check for .bf
11109 rather than just checking whether the second character is b and
11110 the third character is f.
11111 (obj_coff_val): gcc can generate values which we don't handle
11112 correctly; discard information for now, since it only affects the
11113 debugging information.

11115 (yank_symbols): Don't merge labels.
11116 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

11118 set segment address if ZERO_BASED_SEGMENTS.
11119 (obj_coff_section): Accept and ignore a trailing quoted string, as
11120 used in AT&T i386 syntax.

11266 z8000 documentation
11267 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
11270 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
11272 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
11274 * subsegs.h: add extern to segment_info declaration.
11276 * read.h: added extern declarations for comment_chars,
11277 line_comment_chars, and line_separator_chars.
11278 read.c, app.c: removed definitions of comment_chars,
11279 line_comment_chars, and line_separator_chars.
11281 * tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
11282 still accept (but don't require) OPTIONAL_REGISTER_PREFIX before

11296 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11298 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
11299 constant will not fit in an immediate field.
11300 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

11304 * obj-coff.c (callj_table): Delete global variable.
11305 (obj_emit_relocations): Define it locally here, and only if
11306 TC_I960 is defined.
11308 * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.

11335 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
11337 * Support for i386-sysv.
11338 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
11339 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
11340 be used to set them all to zero as was done before.
11341 (fill_section): segment addresses now set in write_object_file.
11342 (fill_section): Don't set STYP_NOLOAD for .bss section.
11343 (fixup_segment): 386 uses strange common symbol format.
11344 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
11345 compatibility with SVR3.2 linker.

11376 * tc-z8k.c: lots of bug fixes
11378 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
11380 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
11381 #elif, since it is not supported by old compilers.
11382 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
11383 couple of expressions in tc-m68k.c.
11385 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11387 * read.c (cons): If NO_RELOC is defined, use it.
11389 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.

11393 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
11394 local labels to start with a .) and set REGISTER_PREFIX to %.
11395 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
11397 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
11399 * messages.c: Comment changes.
11401 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
11403 * as.h: Test if __STDC__ is defined only, don't test its value.
11404 * messages.c: If __STDC__ is not defined, define NO_STDARG.
11406 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
11408 * listing.c (debugging_pseudo): Add stabs and stabn as things to
11411 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
11413 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
11414 sections starting from zero, rather than making them consecutive.
11415 This makes subsequent reloc calculations easier, esp if the object
11416 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
11417 allocate lcomm in .data rather than in .bss. It seems that some
11418 tools can't cope with a non-zero sized bss before linkage.
11420 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11422 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
11423 throughout. That enum no longer means what we thought it meant.
11425 * tc-m68k.c (md_assemble, md_parse_option): Handle new
11426 "-mno-688[58]1" options.
11428 * tc-m68k.c: Added CPU32 support.
11430 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11432 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.

11441 * Makefile.in (install): if $(tooldir) exists, install as in
11444 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
11446 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
11447 .word is < -32768 or > 32767. The -J flag causes the error to be
11448 ignored. This is to catch over-sized switches generated by gcc on
11449 systems which don't support the broken .word hack.
11450 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
11451 write.c (fixup_segment): check for signed .word overflow if
11452 WARN_SIGNED_OVERFLOW_WORD.
11454 * write.c (fixup_segment): fixed missing parens in expression
11455 checking for byte or word overflow.
11457 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
11458 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
11459 WARN_SIGNED_OVERFLOW_WORD.
11461 * obj-coffbfd.c (fixup_segment): fixed missing parens in
11462 expression checking for byte or word overflow.
11464 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11466 Support for i386 coff
11467 * obj-coffbfd.h : added stuff
11468 * tc-i386.c (tc_coff_fix2rtype): new function
11469 * tc-i386.h : new coff defines
11471 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
11473 * input-scrub.c (input_scrub_push): call input_file_begin, not
11475 messages.c (as_perror): print ": " between the passed in error and
11476 the strerror, like perror does.
11478 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
11480 * Makefile.in: use gas_target instead of modifying target_cpu.
11481 From Steve Chamberlain:
11482 Makefile.in: Handle m68*-*-coff*.

11485 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
11486 Motorola and MIT syntax; gas can now assemble either type of
11488 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
11489 From Steve Chamberlain:
11490 m68kcoff.mt: for m68k COFF.
11491 obj-coffbfd.c: (fixup_mdeps) added
11492 (size_section) removed bad sanity check
11493 (fill_section) added rs_machine_dependent case
11494 (write_object_file) call fixup_mdeps
11495 (fixup_segment) set fx_subsy to 0.
11496 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
11498 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
11501 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11503 * Makefile.in (LIBS): Include opcode library.
11505 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

11524 * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
11525 tc-i960.c (md_ri_to_chars): Always output bout object file in
11526 little endian byte order (used to use endianness of host).
11528 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11530 * config/tc-m68k.c (init_table): Now const. Always include 68851
11531 data, so that "bc" is available to 68040 cache instructions.
11532 Added "tt0", "tt1", and 68ec030 variants.
11533 (md_assemble): Complain if 68000 (only) and 68881 are specified.
11534 (enum _register): Added TT0, TT1.
11535 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
11536 line number correctly in "internal error" messages. Don't print
11537 architecture-mismatch message for operand errors.
11539 From Colin Smith (colin@wrs.com):
11540 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
11541 than install_operand.
11543 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11545 * listing.c (buffer_line): rewind to the start of include
11546 files, they might be included twice.
11548 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
11550 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
11552 * Makefile.in: defined TARGET_CPU for C code so that it can choose
11553 one element of a family.
11555 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
11557 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
11558 so that we can assemble hand-written libgcc code.
11560 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11562 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
11563 has already been formatted (but may still contain %-characters).
11564 (as_bad): Likewise.
11566 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
11568 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
11569 written with indirection on the last two operands, which can be
11570 either data or address registers. Added a new operand type 'r'
11571 which accepts either register type. Added '(' to notend stuff in

11823 * Makefile.in (install): Install into $(tooldir)/bin, since that's

11903 * Makefile.in, configure.in: removed traces of namesubdir,
11904 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced

11907 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
11908 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11909 copyrights to '92, changed some from Cygnus to FSF.
11911 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11913 * expr.c: If an expression is single comma, then return with
11914 SEG_ABSENT rather than an error - since the sparc front end does
11915 really strange things with things like fbge,a
11917 * as.h: include bfd.h if using many sections
11918 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
11919 local labels didn't work.
11920 * listing.c (list_symbol_table): don't core dump when there's no
11922 * write.c, write.h: call fix_new with the right number of args on

11929 * app.c: MRI compatibility - allow single quote to start a string.
11930 * as.c: fix typo recently introduced.
11931 * as.h : Don't include aout/reloc.h - it's not right for COFF!
11932 * expr.c: Much rewriting, to accomodate MRI syntax for
11933 expressions. Also easier to read now.
11934 * listing.c: Put back defuns
11935 * read.c: modified to accept MRI syntax, put back listing pseudo
11936 ops so that an assembler built with NO_LISTING ignores list ops
11938 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
11939 machine is a SPARC or a 29K.
11940 * config/obj-aout.c: added s_sect pseudo op
11941 * config/obj-coffbfd.c: lints, set the filehdr flags right and
11942 fill in the timestamp.
11943 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
11944 anymore, define all the relocs which the tc-<x> bit will use so we
11945 can translate from them to the coff types.
11946 * config/tc-a29k.c: reloc_type isn't ane enum any more
11947 * config/tc-m68k.c: Added NO_RELOC definition.
11949 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
11951 * Makefile.in: put header files before C source for TAGS; remove
11952 references to non-existent syscalls.h.
11954 * read.c, write.c subsegs.c: back out the .bss changes.
11956 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
11958 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
11960 * a.out.h: removed.
11962 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
11964 * symbols.c (local_label_name): symbols now start with ^A.
11966 * read.c, subsegs.c, write.c obj-coff.c: added handling of
11967 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
11968 generate these sections. .align: will use NOP_OPCODE or 0
11969 for padding. This is just for being nice to the
11972 * expr.c (operand): changed to generate local label "\001L0"
11973 starting with a ^A so that it is recognized as a local label.
11975 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
11977 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
11978 i/o opcodes - inb, inw, outb and outw. string manipulation with
11979 att syntax - scmp, slod, smov, ssca, ssto.
11981 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
11982 to just after .file .
11984 In obj_crawl_symbol_chain() where it tries to put the external
11985 symbols apart, with the condition:
11986 (!S_IS_DEFINED(symbolP) &&
11987 !S_IS_DEBUG(symbolP) &&
11988 !SF_GET_STATICS(symbolP))
11989 it was moving too many symbols out. So I switch it back to the
11991 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
11993 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
11994 so that we don't use the F_RELFLG which make the linker complain
11995 that somebody has stripped the relocation info.
11997 Also, the AIX ld program require that the relocation table
11998 is sorted by r_vaddr like the standard ATT assembler does.
12000 [he also changed the sizeof(struct ...)'s into the coff
12001 style FOOSZ macros. I'm not sure this is right, but I can't
12002 remember why. xoxorich.]
12004 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
12006 * Makefile.in, configure.in, doc: use the doc. Build it, install

12013 * configure.in: use the new atof-ns32.c for ns32k.
12015 * write.c: comment change only.
12017 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
12018 aren't yet integrated.
12020 * tc-i860.[hc]: blew off the dust. Something must still be done
12021 about conflicting relocation types.
12023 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
12026 * tc-i960.c, tc-sparc.c: white space and comments only.
12028 * tc-a29k.h: delete duplicate macro definition.
12030 * new file atof-ns32k.c copied from hack's last unreleased gas.
12032 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
12034 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
12037 * nearly everything. flush ChangeLog, package as gas-1.92.1.
12038 ChangeLog's prior to this are sketchy at best. I have logs.
12039 They just aren't ChangeLogs.
