4455 Fri Oct 14 19:06:46 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4457 * Makefile.in (BISON): Use bison -y, not bison.

4471 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
4473 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
4474 it's better to use the one in libiberty.
4476 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4478 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
4479 change; it breaks the rs6000 support, and doesn't seem to be
4480 needed.
4482 Wed Oct 12 11:56:50 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
4484 * config/tc-i386.h,te-netbsd532.h (TARGET_FORMAT): Changed to

4489 * config/tc-ppc.c (ppc_fix_adjustable): Resolve symbol values
4490 rather than explicitly adding the frag address.
4491 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark
4492 the end of the line numbers; this replaces the zero entry which
4493 used to be added by coff_add_linesym, removed Oct 7.
4494 (coff_adjust_section_syms): Ignore sections with no seginfo.
4496 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4498 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a
4499 "stage" symlink to the appropriate stage* directory, and use it
4500 instead in the -B options.
4501 (comparison): Revert yesterday's change.
4503 Tue Oct 11 16:48:11 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4505 * config/tc-sparc.c (tc_gen_reloc): For non-a.out relocations, if

4508 Tue Oct 11 15:24:00 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
4510 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
4511 for an embedded PIC switch expression, since the definition of
4512 S_IS_LOCAL was changed.
4514 Tue Oct 11 15:05:11 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
4516 * Makefile.in (comparison): When comparing as.new or gasp.new, try
4517 running the binary through sed to avoid differences due to
4518 "stage1" or "stage2" having been written into the binary.
4520 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
4522 ELF symbol size handling, based on code from Eric Youngdale:
4523 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an
4524 expression pointer to the symbol structure, used for `size'
4525 expressions that couldn't be reduced to constants when initially
4526 processed.
4527 (elf_frob_symbol): Declare.
4528 (obj_frob_symbol): Call elf_frob_symbol always, rather than
4529 ecoff_frob_symbol only if ECOFF_DEBUGGING defined.
4530 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
4531 Clear sy_obj field.
4532 (obj_elf_size): Deleted unused code. If size is non-reducible
4533 expression, allocate some storage for the sy_obj field and copy
4534 the expression.
4535 (elf_frob_symbol): New function. Computes sizes, calls
4536 ecoff_frob_symbol if appropriate.
4538 * write.c (fixup_segment): For i386 elf and coff (for now), don't
4539 add in value of symbol from another defined section of the file.
4541 Fri Oct 7 17:54:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4543 * config/tc-m88k.h (TC_KEEP_FX_OFFSET): Define.
4544 * config/obj-coff.c (do_relocs_for): Test only TC_KEEP_FX_OFFSET,
4545 rather than both it and TC_M88K.

4568 * config/obj-ecoff.c (obj_pseudo_table): Accept .esize and .etype
4569 as synonyms for .size and .type.
4571 Wed Oct 5 00:08:10 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4573 * config/obj-coff.c (coff_frob_section): Remove assert about
4574 section alignment.
4575 * config/tc-sparc.c (md_section_align): Use section alignment, not
4576 xvec align_power_min field.
4578 Fri Sep 30 19:05:20 1994 Pat Rankin (rankin@eql.caltech.edu)
4580 * vmsconf.sh (make-gas.com): handle DCL verification to enable
4581 sensible feedback to the user while gas is being built.
4583 Fri Sep 30 16:23:31 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

4586 for now.
4587 (diststuff): New target; builds DISTSTUFF.
4588 (realclean): Separate target, depend on clean and distclean, then
4589 delete DISTSTUFF.
4590 * make-gas.com: Deleted.
4592 * config/tc-i386.c (i386_validate_fix) [BFD_ASSEMBLER]: New
4593 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
4594 reloc for "foo".
4595 (i386_operand): Don't look up section symbol for
4596 undefined_section.
4597 (reloc): Always permit return of 8- and 16-bit relocation types.
4598 Add a space after "pc-relative" in the error message.
4599 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
4600 BFD_RELOC_386_GOTOFF relocs.
4601 (i386_operand): For any GOTOFF reloc, convert it to a BFD_RELOC_32
4602 with a "foo-GOT" value.
4603 * config/tc-i386.h (i386_validate_fix): Declare it.
4604 (TC_VALIDATE_FIX): New macro -- call it.
4605 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.
4607 * as.h: If __STDC__ is not defined and varargs.h is available, use
4608 it rather than stdarg.h.
4610 * write.h (struct fix): Added new bitfield fx_plt, for fixups
4611 referring to PLT entries.
4612 * write.c (fix_new_internal): Initialize fx_plt to zero.
4613 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
4614 Don't adjust fx_offset by frag address, since S_GET_VALUE now
4615 includes the frag address.
4616 (fixup_segment): Changed local var PCREL to type int, added PLT.
4617 If PC-relative fixup refers to a PLT entry for a symbol in the
4618 current section, don't reduce it.
4620 * write.c (adjust_reloc_syms): Exit loop through a label. If
4621 DEBUG5 is defined, print out each fixup before and after
4622 processing.
4623 (fixup_segment): If DEBUG5 is defined, print out each fixup before
4624 and after processing.
4625 (print_fixup): Added prototype. Show address on first line. Show
4626 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if
4627 NEED_FX_R_TYPE is defined.
4629 * symbols.c (print_symbol_value_1): Check S_IS_LOCAL, S_IS_EXTERN,
4630 S_IS_DEBUG, S_IS_DEFINED also.

4639 * write.c (print_fixup): Print source location on first line.
4640 Show fx_r_type and fx_addsy fields.
4642 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4644 * configure.in: Set bfd_gas for all sparc targets in one place,
4645 instead of separately for each. Correctly handle user-supplied
4646 "--enable-bfd-gas" option.
4648 * gdbinit.in: Move "break abort" to end, in case gdb complains.
4650 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
4651 Use PARAMS macro.
4653 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
4654 processing if add_symbol is undefined or in expr_section.
4655 (resolve_symbol_value, case O_add): For symbol plus
4656 constant-valued symbol, convert to O_symbol and re-reduce.
4657 (S_GET_VALUE): If symbol needs resolving, resolve it.
4658 (indent_level): No longer static.
4659 (print_symbol_value_1): Don't print frag address if it matches
4660 zero_address_frag. Don't print "resolving" if already resolved.
4661 Print segment name. Don't call print_expr_1 on an undefined
4662 symbol.
4663 (print_expr_1): Fix whitespace before printing X_add_number.
4665 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
4666 not symbol_new, for symbols holding expression values.
4667 * expr.h (make_expr_symbol): Move declaration here.
4668 * write.c (fix_new_exp): Handle O_add by creating an
4669 expression-valued symbol, and calling fix_new_exp recursively.
4670 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
4671 undefined symbol and a constant, fold the constant into the fixup,
4672 and refer to the undefined symbol directly. Then process the
4673 fixup again from scratch.
4674 (write_object_file): Before calling adjust_reloc_syms, make a pass
4675 through the symbol list trying to resolve values.
4677 * write.c (print_fixup): New routine, for debugging.
4678 (write_relocs): Call bfd_install_relocation. Deleted various
4679 hacks for working around problems with bfd_perform_relocation.
4681 * Makefile.in (VERSION): Update to 2.4.90.
4683 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4685 * Makefile.in (gasp.o): Depends upon config.h.
4687 * config/tc-mips.c: Include subsegs.h.
4688 (md_apply_fix): If an unconditional b or bal overflows, and we are
4689 not assembling PIC code, replace it with a j or jal.
4691 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
4692 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
4694 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4696 * write.c (write_relocs): Add file name and line number to
4697 as_fatal calls. Handle bfd_reloc_overflow case specifically when
4698 RELOC_EXPANSION_POSSIBLE.
4700 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4702 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
4703 here. Use them for deciding which PRINTF*LIKE macro definitions
4704 to use.
4705 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
4706 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
4707 default definitions matching what we were doing before.
4708 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
4709 always use the varargs form if not using stdarg. It's safe to
4710 always use vfprintf, because libiberty will provide it if the
4711 native system doesn't. Also, always make format be const.
4712 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
4714 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4716 * config/tc-mips.c (load_register): Always use addiu when adding a

4719 is only 32 bits.
4721 * symbols.h (copy_symbol_attributes): Declare.

4728 deciding whether to record it.
4729 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
4730 false (if defined) as well as checking for reg_section.
4731 (listing_listing): Iterate fetching lines while line number is too
4732 low, and we haven't run off the end of the input file.
4734 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
4736 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
4738 * ecoff.c (ecoff_generate_asm_lineno): check if
4739 current_stabs_filename is NULL before strcmp.
4740 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
4741 checking.
4743 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4745 * config/ho-*.h: Now-unused files deleted.
4747 * symbols.c (copy_symbol_attributes): New function. Copies BFD
4748 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
4749 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
4750 zero. Don't call obj_frob_forward_symbol.
4751 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
4752 X_add_number is zero.
4753 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
4755 * config/tc-i960.c: Lots of whitespace, comment reformatting,
4756 using GNU indent.
4757 (strchr): Don't declare.
4758 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
4759 md_estimate_size_before_relax, md_ri_to_chars,
4760 md_create_short_jump, md_create_long_jump.
4761 (brtab_emit): Use data_section, not SEG_DATA.
4763 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
4765 * config/vms-conf.h: new file, manually derived from conf.in.
4766 * config-gas.com: use it, and eliminate obsolete "host.h".
4768 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4770 * config/tc-ppc.c (ppc_current_block): New static variable.
4771 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
4772 ppc_current_block. Don't move around any stab symbol, just those
4773 for common symbols.
4774 (ppc_bs): Set ppc_current_block.
4775 (ppc_es): Clear ppc_current_block.
4776 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
4777 from the csect of the enclosing block.
4779 * config/tc-mips.c (insns_since_cache_access): Remove.
4780 (append_insn): Remove setting of insns_since_cache_access, and
4781 special 4600 handling; it turns out not to be required.
4783 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4785 * config/tc-mips.c (md_shortopts): Remove E.
4786 (md_longopts): Add EB and EL.
4787 (md_parse_option): Handle -EB and -EL as separate options, rather
4788 than as a single -E option with an argument.
4790 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
4792 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
4793 involving global symbols too.
4795 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4797 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
4799 * configure.in: Test for remove, not delete. Fix cross-assembler
4800 test.
4801 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
4802 remove, not delete.
4804 * read.c (pseudo_set, case O_symbol): If
4805 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
4806 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
4807 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
4809 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
4811 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
4812 many others): new macros; values obtained from "DSTRECRDS.SDL".
4813 * config/obj-vms.h (various): use them.
4814 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
4815 representation (only enum bitfields can avoid being bitstrings).
4816 (bitfield_suffix, setup_basic_type): new routines.
4817 (VMS_typedef_parse): use them. Now recognize bitfields of all
4818 integral types, not just type `int'. Caveat: the representation
4819 used for bitfields still does not work for objects placed in
4820 registers, and gcc's optimizer sometimes puts small structs there.
4822 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
4824 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
4825 bit from const_flag.
4826 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
4827 (tc_frob_label): define this to call vms_check_for_special_label,
4828 and declare the latter.
4829 * config/obj-vms.c (vax_g_doubles): declare this file-scope
4830 variable.
4831 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
4832 (vms_check_for_special_label): new routine (tc_frob_label).
4833 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
4834 and `gcc2_compiled.' labels; they won't reach here any more.
4835 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
4836 double', use `vax_g_doubles' flag to select type of double.
4837 (VMS_write_object_file) [traceback setup]: don't pass symbols
4838 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
4839 and TBT_Routine_End functions.
4841 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
4843 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
4844 S_GET_VALUE() to avoid many repeated function calls.
4845 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
4846 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
4847 gets requested. [All the HACK_DEC_C_STARTUP code appears to
4848 be obsolete; gcc does it automatically for vms target. It's
4849 also misnamed, because it is for the "VAX C" run-time library,
4850 not the newer "DEC C" one which has much different startup code.]
4851 {various}: use `S_SET_xxx(symbol,new_value)' rather than
4852 `S_GET_xxx(symbol) = new_value'.
4854 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4856 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
4857 not &bfd_abs_section.
4859 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4861 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
4863 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
4865 * expr.c (expr): Don't reduce the difference of two symbols in the
4866 same frag if the symbols are not in normal sections.
4868 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
4869 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
4870 (obj_attach_unwind_info): Do not define. Not needed anymore.
4871 * config/tc-hppa.c: Delete whitespace at EOL.
4872 (struct hppa_fix_struct): Delete fx_unwind field and all references.
4873 (fix_new_hppa): Last arg is now a pointer to an int. Do not
4874 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
4875 fixups, store 32bits of unwind information in the fx_addnumber
4876 field of the fixup.
4877 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
4878 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
4879 pointer to 32 bits of unwind info.
4880 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
4881 pointer to the dummy symbol; set the addend field to fx_addnumber.
4882 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr

5792 * ecoff.c (ecoff_build_aux): Call swap_tir_out and swap_rndx_out
5793 via backend pointer, not directly.
5795 Fri Jun 17 18:05:06 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

5835 (DBG_S_C_REAL8_G, DBG_S_C_COMPLX8_G): G_float versions of
5836 REAL8 and COMPLX8; not used yet, because gcc outputs the same
5837 .stabs for `double' regardless of whether `-mg' is used.
5838 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
5839 for gcc2's predefined types "complex float", "complex double",

5849 $8,%hi(foo); lw $8,%lo(foo)($8)'' work correctly.
5851 Mon Jun 13 12:08:52 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5853 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt

5859 * read.c (pseudo_set): Only preserve external bit for OBJ_AOUT and
5860 OBJ_BOUT if not BFD_ASSEMBLER.
5861 * config/aout_gnu.h (N_WEAKU, N_WEAKA, N_WEAKT, N_WEAKD, N_WEAKB):
5862 Define as in ../include/aout/aout64.h.

5878 Wed Jun 8 06:28:37 1994 Bill Cox (bill@cygnus.com)
5880 * Makefile.in (check): Delete as.new dependency, so that
5881 regression test doesn't trigger an assembler build.

5891 (macro): Correct M_LI_SS SVR4_PIC/EMBEDDED_PIC case. After M_LI_D
5892 or M_L_DOB or label dob, force a new frag to avoid getting
5893 confused in tc_gen_reloc.
5894 (mips_ip): Use RDATA_SECTION_NAME, not .rdata.
5895 (s_change_sec): Likewise.
5897 Fri Jun 3 23:35:36 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5899 * read.c (emit_expr): Use memset to zero out memory, rather than
5900 going through md_number_to_chars. This permits handling symbolic
5901 arguments when the size is larger than sizeof (valueT), if
5902 TC_CONS_FIX_NEW is prepared to handle the case (as it is on MIPS).
5904 Fri Jun 3 12:50:13 1994 David J. MacKenzie (djm@rtl.cygnus.com)

5916 config/tc-i960.c, config/tc-m68k.c, config/tc-mips.c,
5917 config/tc-vax.c: Use the new flag variables instead of flagseen.
5918 * config/tc-vax.c [OBJ_VMS]: Recognize -+, -1, -v, and document in
5919 usage.
5921 * as.c (show_usage): Remove target specific messages;
5922 instead, call md_show_usage.
5923 (parse_args): Use getopt_long_only. Take pointers to argc and
5924 argv.
5925 (main): Pass parse_args pointers.
5926 * as.h: Remove 3 variables that are redundant with flagseen.
5927 * as.c, messages.c: Change their users to use flagseen.

5942 * doc/as.texinfo: Document all of the target-independent command
5943 line options.
5945 Thu Jun 2 12:07:25 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

5953 m68040_control_regs, m68060_control_regs): New arrays.
5954 (control_regs): New pointer.
5955 (m68k_ip): Use control_regs instead of testing CPU every time.
5956 Use last_movec_reg too. In error messages, handle 68060, and
5957 print 68060 for mfloat, too.
5958 (m68k_init_after_args): Handle "68060". Use m68040up for making
5959 m68851 choice. Set control_regs.
5960 (md_parse_option): Handle "68060".
5961 * configure.in: Setting cpu_type, recognize m68060 too.

5968 lower-case, in case we're ignoring case of opcodes in the input
5969 file.

5972 type formats.
5974 * config/tc-alpha.c (machine): New variable.
5975 (load_insn): New macro.
5976 (load_insn_table): New function.
5977 (md_begin): Call load_insn_table, once for basic instructions and

5999 * Makefile.in (VERSION): Updated to cygnus-2.3.1.
6001 * config/obj-vms.c: Replaced unchecked uses of malloc with
6002 xmalloc.
6004 * listing.c (list_symbol_table): Only test BFD64, not
6005 BFD_ASSEMBLER too.
6007 * config/obj-coff.c (fixup_segment) [BFD_ASSEMBLER]
6008 [DIFF_EXPR_OK]: Don't check pcrel, just convert it.

6028 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
6029 for gcc2's predefined types "long double" (same as double, as
6030 per gcc's current state), "long long int", "long long unsigned
6031 int", and final `otherwise' case (to avoid uninitialized type
6032 and size fields). [caveat: predefined types "complex int",
6033 "complex float", "complex double", and "complex long double" are
6034 still missing.]
6036 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
6037 of 0, because the latter indicates success rather than failure
6038 when passed to `exit' or return from `main' compiled by gcc2.

6247 * listing.c (list_symbol_table): Print "NO DEFINED SYMBOLS" and
6248 "NO UNDEFINED SYMBOLS" if there aren't any, instead of displaying
6249 the header with an empty list.
6251 * config/obj-coffbfd.c (fill_section): Check COFF_NOLOAD_PROBLEM
6252 also before setting STYP_NOLOAD for .bss section.
6254 * config/tc-m68k.c (flag_reg_prefix_optional): New variable.
6255 Initialized to value of REGISTER_PREFIX_OPTIONAL, if defined, or
6256 zero.

6271 * config/tc-m68k.c (DATA, ADDR, SP, FPREG, COPNUM, BAD, BAC):
6272 Define as macros instead of enumerators, since the Apollo compiler
6273 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum

6282 (COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
6284 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
6285 can be used within a label name.
6287 * config/tc-m68k.h (m68k_init_after_args): Declare.
6288 (tc_init_after_args): Define as m68k_init_after_args.
6289 * config/tc-m68k.c (m68k_init_after_args): New function,

6294 Mon Apr 25 16:19:17 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6296 * doc/Makefile.in (clean, distclean): Remove asconfig.texi.

6305 * config/obj-ecoff.c (ecoff_frob_file): Use bfd_ecoff_set_gp_value
6306 and bfd_ecoff_set_regmasks to set the GP value and the register
6307 masks, rather than using the now obsolete fake .reginfo section.
6309 Fri Apr 22 15:17:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6311 * listing.c (list_symbol_table): Don't print register symbols as
6312 undefined.
6314 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
6315 underscores, since symbol_new will already have done it.
6316 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
6318 * as.c (main): If tc_init_after_args is defined, invoke it after
6319 all arguments have been processed.
6321 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
6322 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
6323 section instead of .text. Call create_target_segments.
6324 * read.c (demand_copy_string): No longer static.
6326 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6328 * config/tc-mips.c (append_insn): Permit branches to be switched
6329 with the preceding instruction even if .set nobopt has been seen.
6330 .set nobopt actually controls whether to bring up an instruction
6331 from the branch target, which gas does not currently support.
6333 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6335 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

6363 output.
6365 * config/ho-sysv.h: Include string.h.

6376 (pa_spaces_begin): Set BFD section flags for all built-in
6377 subspaces.

6387 as well as as.new.
6389 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6391 * expr.c (operand): Try to parse "0f" and "0b" sequences as
6392 floating point and binary numbers respectively; if it doesn't
6393 work, treat them as local labels.
6395 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
6396 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
6398 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
6399 (Charles Bailey):
6400 * vmsconf.sh: In generated file, get ".obj" suffix right, build
6401 source files from other directories into objects in the current
6402 directory, and specify PSECT attributes explicitly to linker.
6403 Also added missing label.
6404 * Makefile.in (stamp-mk.com): Reference new variable
6405 VMS_OTHER_OBJS for list of non-local object files, instead of
6406 listing them here.
6407 (VMS_OTHER_OBJS): New variable, added more libiberty files.
6408 * make-gas.com: Regenerated.
6410 * config/ho-vms.h (unlink): Define as delete.
6412 * config-gas.com: Fix quoting on TARGET_CANONICAL definition.
6413 Delete files before creating them.

6420 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
6421 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
6422 argument, the reloc type.
6423 (load_register): Pass reloc type to macro_build for 'u'.
6424 (macro): Likewise. For M_LA_AB permit a difference expression
6425 when generating embedded PIC code between an arbitrary symbol and
6426 a symbol in the .text section.
6427 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
6428 BFD_RELOC_PCREL_LO16 to be emitted.

6437 order.
6438 (subseg_get): Clear newly allocated seginfo, set its pointer slots
6439 to NULL instead of 0.
6441 Mon Apr 11 09:00:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6443 * config/tc-hppa.c (pa_procend): Handle case where label was
6444 defined after the .proc directive.
6446 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
6447 procend for a procedure without a name.

6468 (hppa_tc_symbol): Likewise.
6470 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
6471 elf_tc_make_sections stuff. It was there to support PA braindamage
6472 which has been fixed, and in the case of elf_tc_make_sections is
6473 redundant with elf_tc_final_processing.
6475 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6477 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the
6478 manufacturer.

6486 PC relative fixup.
6487 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
6488 value into the file if the fixup will not generate a reloc.

6492 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
6493 don't spew remainder of input file in error message.
6494 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
6495 message with reloc type and try to process remainder of file.

6498 targets, now explicitly checking $(srcdir) for info files.
6499 (install-info): Depend on both of them; do nothing more.

6507 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
6508 flag rather than signedp field. Only permit extended range if
6509 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
6510 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
6512 * config/tc-ppc.c (ppc_size): New static variable.
6513 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
6514 (md_begin): If an instruction has a size specific flag set, only
6515 add it if we are assembling that size.

6519 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
6520 cross section PC relative relocs right for COFF and ELF.

6536 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
6537 and -many (all architectures).

6541 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
6542 involving a function symbol which is not a plabel to zero.
6543 (md_apply_fix): Never pass a function symbol to field_adjust.

6551 branch with an instruction that uses $at, in case the branch is
6552 later expanded.
6553 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
6554 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
6555 to make it pcrel_offset.
6556 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
6557 reloc->address; another gruesome hack to get gas reloc handling to
6558 do the right thing.

6570 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
6571 tested by code that might want to emit a LITUSE reloc.
6572 (emit_unaligned_io): New function. Currently calls md_assemble,
6573 but it should eventually be converted to generate the insn itself
6574 and call emit_insn directly.
6575 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
6576 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
6577 emit_bis_r): Likewise.

6605 (load_address): Handle EMBEDDED_PIC.
6606 (macro): Handle EMBEDDED_PIC in all PIC cases.
6607 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
6608 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
6609 -non_shared to use NO_PIC (this is how the Irix 5 assembler
6610 works). Do not permit -G with SVR4_PIC.
6611 (s_abicalls): Warn if -G was used, and force -G 0.
6612 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
6613 anything but a.out, not just for ELF. For ECOFF, don't generate a
6614 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
6616 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.

6620 * config/tc-hppa.c (create_new_space): Use ints, not chars as
6621 parameters to avoid losing when compiling with HP CC.
6622 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
6624 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6626 * Makefile.in (config-stamp): If `defs' is defined, emit a
6627 preprocessor directive to create a macro named by this value into
6628 config.new; don't explicitly go for BFD_ASSEMBLER.
6629 * configure.in: Define `defs', not `BFDDEF'. Set it to
6630 MANY_SEGMENTS for any obj-coffbfd target.
6631 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
6632 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,

6651 unconditionally.
6653 * write.c (set_symtab): Define only if BFD_ASSEMBLER.

6659 Fri Mar 18 20:09:16 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6661 * write.c (symbol_table_frozen): New variable, to be set after
6662 bfd_set_symtab is called.
6663 (dump_section_relocs): Note whether a symbol is a section symbol
6664 or not.
6665 (adjust_reloc_syms): For now, always supply an absolute symbol for
6666 fixups without symbols but not yet `done'. Use section_symbol to
6667 get the symbol, instead of going directly for abs_symbol.
6668 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
6669 reloc is not a section symbol and is not in the symbol table.
6670 (set_symtab): New function, broken out from write_object_file.
6671 Counts symbol table instead of relying on an earlier count.
6672 (write_object_file): Call set_symtab, but do it after potentially
6673 invoking the *_frob_file macros. Don't bother counting symbols.
6674 Call symbol_remove, instead of expanding it in place. Moved the
6675 conditionalized `object_file_size' declaration down to
6676 conditionalized block where it's used. When using the absolute
6677 symbol for a fixup without a symbol, set sy_used_in_reloc.
6678 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
6679 the correct symbol for the absolute section.
6681 * subsegs.c (section_symbol): Use symbol_new instead of
6682 symbol_make, since we may want it to go into the symbol table.
6683 Make the new symbol have internal linkage. If
6684 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
6685 symbol with the newly created GAS symbol.
6686 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
6687 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
6688 New macro.
6689 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.

6693 (sparc_ip): Use it.
6694 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
6695 (sparc_ip, label "immediate"): Reject constants for pcrel
6696 instructions only if the relocation type indicates a "call"
6697 instruction and the offset is within range of a "jmpl %g0". If
6698 it's not in range, use the absolute section symbol plus an offset.
6699 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
6700 _BASE13 cases.
6701 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
6703 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
6704 MANY_SEGMENTS).
6706 * configure.in: Eliminated all targets using obj-coff but not
6707 defining BFD_ASSEMBLER; I think all such targets that are
6708 supported will be matched by real CPU-OS combinations earlier in
6709 the case statement.
6710 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
6711 some comments about the dpx2 configuration, but left it disabled,
6712 since it couldn't be reached before.
6713 (target a29k-amd-ebmonold): Deleted.
6715 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

6722 * config/tc-mips.c (mips_ip): Only accept overly large values for
6723 the 'j' operand if there are no further alternatives for this
6724 instruction.
6726 * config/obj-coffbfd.c (adjust_stab_section): Initialize
6727 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
6728 is not SEG_UNKNOWN rather than checking whether it is >= 0.
6730 * config/tc-mips.c (mips_align): Take new argument, label, and use
6731 it instead of global insn_label.
6732 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
6733 call to mips_emit_delay and pass it to mips_align.
6735 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6737 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
6739 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
6740 argument to a .callinfo directive. Don't loop forever on errors.
6742 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
6743 use pre-defined registers as arguments.
6745 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

6748 S_IS_EXTERNAL when deciding whether to discard a symbol.
6750 * config-gas.com: Scan Makefile.in, not version.c, for current
6751 version number. Delete all versions of temp files when finished
6752 with them. Create config.h.
6754 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
6755 values to reduce number of lookups with S_GET_VALUE. Skip debug
6756 symbols to avoid "a really nasty bug". (From Holger Teutsch,
6757 holger@botbso.rhein-main.de.)
6758 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
6759 field. (Also from Holger Teutsch.) Watch for a would-be register
6760 mask that spans frags.
6762 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
6763 this_base, not line_base. (Patch from Andreas Arens,
6764 ari@obelix.av.rwth-aachen.de.)
6766 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
6767 look local if they're exported or undefined. Used to be done for
6768 i960 only.
6770 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
6771 Get it from the looked-up symbol, instead of using the string from
6772 the input stream, which is no longer null-terminated.
6773 (LEX_PCT): New macro, defaults to 0.
6774 (lex_type): Use it for `%'.
6776 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
6777 (vip_op): Now static, and returns void. Callers changed. Added
6778 forward decl.

6780 detected.
6781 (op_hash): Let default initialization suffice.
6783 * Makefile.in (literal.o): Provide dependencies.
6785 * configure.in: Set new makefile variable OPCODES_LIB.
6786 * Makefile.in (LIBS): Use it.
6788 * Makefile.in (make-gas.com, stamp-mk.com): New targets.

6826 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
6827 0xffff for 'j' to be compatible with MIPS assembler. These
6828 numbers are actually treated as negative.

6843 MANY_SECTIONS.
6844 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

7236 call it on a copy of the name argument.
7238 * write.c (write_object_file): Simplified usage of obj_frob_symbol

7437 * write.c (write_object_file): If EMIT_SECTION_SYMBOLS is false,
7438 don't write out a section symbol even if it's used in a

7441 it's true use.
7442 (EMIT_SECTION_SYMBOLS): Default to 1.
7443 (adjust_reloc_syms): Don't create a new symbol for an absolute
7444 reference; just use the absolute section symbol.

8895 OPTIONAL_REGISTER_PREFIX if either is already defined.
8897 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
8899 * configure.in: Set bfd_gas for all sparc targets. Added facility
8900 for keeping or rejecting configurations still under development;
8901 default is to assume production environment, and reject configs
8902 still being worked on. Mark Elf configurations (except sparc and
8903 i386) as developmental. Deleted cases matching some generic names
8904 in favor of more specific names. (E.g., when we get Alpha
8905 support, we'll still only support VMS for Vax.)
8907 * config/tc-sparc.h (md_end): New macro.
8908 * config/tc-sparc.c (md_end): Function deleted.
8909 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd
8910 version compiling. All sparc targets will use bfd now.
8911 * tc.h (md_end): Don't declare if it's defined as a macro.
8913 Changes from Jeff Law and Peter Hoogenboom:
8915 * read.c (next_char_of_string): Limit octal character constants to
8916 three digits.
8918 * config/tc-hppa.h: Major cleanup. Use GNU-style comments. Warn
8919 against placing additional object-file dependent code here. Warn
8920 against contaminating all of GAS with the internals of tc-hppa.c
8921 through inclusion of tc-hppa.h. Delete all forward declarations
8922 for functions only used within tc-hppa.c, likewise for structures,
8923 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
8924 conditional code in a few small places.
8926 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
8927 structures, global variables, forward declarations together.
8928 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
8929 conditional code -- try to group conditional code together
8930 into a few places. Make all functions and variables which
8931 are only used within tc-hppa.c static. PARAMize all functions.
8932 Add comments to functions. Delete unused functions, variables,
8933 #defines, etc. Delete unused members within structures. Delete
8934 ldil;ble hacks -- it is believed they were installed to work
8935 around old gas bugs. Avoid using mixed case for local
8936 functions, variables, and structures. Fix formatting problems
8937 not found by GNU-indent. Add FIXME notices for things which
8938 should be worked on the near future. Delete lots of old
8939 useless (1.36 PA-SOM) code.
8941 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
8942 field of the fixS structure. Needed to build unwind
8943 descriptors correctly.
8945 * write.c: (fixup_segment): Allow expressions such as
8946 sym1-sym2+const as long as sym2 is $global$.
8948 * write.c (adjust_reloc_syms): Provide a hook so that a target
8949 cpu configuration can reject certain relocation reductions.
8950 * config/tc-hppa.h (tc_fix_adjustable): New macro. Only accept relocations
8951 which do not involve function symbols.
8953 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
8954 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
8955 STAB_FIXUP macro.
8956 * config/tc-hppa.c: Likewise.
8958 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
8959 of elf32_symbol_type.
8960 (pa_export_args): Likewise.
8961 (elf_hppa_final_processing): Likewise.
8962 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed
8963 anymore?)
8964 (hppa_tc_make_sections): Do not declare elf_get_symtab_map any
8965 ore.
8967 * config/tc-hppa.c: (md_section_align): Align all sections to
8968 a multiple of the section alignment rather than always a
8969 multiple of 8.
8971 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
8972 bits are zero (eg they specify no relocations), then do not even
8973 bother adding their entries to thesymextn section.
8975 Thu Oct 21 15:44:55 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
8977 * config/tc-sparc.c (md_parse_option): Accept and ignore -sparc
8978 option, which is used by the SunOS make default .s.o rule.
8980 Wed Oct 20 12:26:33 1993 Ken Raeburn (raeburn@rover.cygnus.com)
8982 * config/tc-sparc.c (sparc_ip, label "immediate"): Convert relocs

9004 characters in state 6.
9005 * read.c (next_char_of_string): Accept \Xh* and \xh* where h* are
9006 hexidecimal digits.
9008 * config/tc-i386.c (md_apply_fix_1): Make cross segment calls work
9009 for ELF by hacking around bizarre bfd_perform_relocation behaviour
9010 that I don't dare change.
9012 Thu Oct 14 11:33:25 1993 Michael Meissner (meissner@osf.org)
9014 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
9015 call strchr for each character to see if it is a special char,
9016 instead add a second loop over special_chars. Set alignment
9017 of text, data and bss sections to 4.
9018 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
9019 used again.
9020 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
9021 ELF, since the ELF object format does not have these type of
9022 relocations. Change the abort into as as_bad and return
9023 BFD_RELOC_NONE to silence compiler warnings.
9024 (md_assemble): Keep track of the instruction size. Allow white
9025 space between the $ and the constant for compatibility with older

9040 for st_StaticProc just like st_Proc.
9042 * write.c (relax_and_size_all_segments): Moved #endif for OBJ_BOUT
9043 so that OBJ_BOUT doesn't forget to adjust all the fragments in the
9044 .bss section.

10302 * config/tc-m88k.c, config/tc-m88k.h: Numerous changes to bring
10303 m88k port up to date, and to add COFF support.
10305 Wed Jul 14 15:09:32 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

11230 makeinfo search path
11232 * doc/h8.texi: new file; conditional settings for GAS manual

11249 * config/obj-ecoff.h (ecoff_build_lineno): Make ilineMax in
11250 symbolic header match cline in FDR; the native linker seems to

11409 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
11410 a29k .bss section; the mondfe program doesn't like it.

11455 process relocs if there aren't any relocs to process. Avoids
11456 malloc/free bug on SCO too.
11458 * as.h: Move local include files below system include files, to
11459 avoid some redefinition complaints on some systems.
11460 (const, volatile): Don't need these conditionally defined if we
11461 use CONST and VOLATILE from ansidecl.h.
11462 (seg_name): Use CONST, not const.
11464 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)

11477 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
11479 * Makefile.in: add dvi target; as-$(config).texinfo might live in

11512 lines; I don't think that can be done portably.
11513 * config/tc-mips.c (macro): Use $AT if target register is zero in
11514 load instruction, which it can be for a floating point load.
11516 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)
11518 * write.c (write_contents): Compute the relocs before writing out

11525 by the section vma.
11527 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
11528 z8k-opc.h, not z8k.h.
11530 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf

11554 * Makefile.in: Generate it, putting in only the version number
11555 itself.
11556 (VERSION): New variable.
11557 * as.c: Include config.h.
11558 (main): Reformatted version string. Include target alias. Don't
11559 print if not requested (i.e., unknown -v argument).

11562 (main): Call strdup instead.
11564 * configure.in: Handle all 68300 series chips.
11565 * config/tc-m68k.c: Include config.h.

11581 support.
11583 * config/tc-mips.h (TARGET_FORMAT): Define based on OBJ_AOUT vs.
11584 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
11585 (struct loc, struct proc, struct file): Moved to tc-mips.c within
11586 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
11587 * config/tc-mips.c: Rearranged for ECOFF support. Added
11588 prototypes for all static functions. Moved existing minimal
11589 debugging format support info #ifndef OBJ_ECOFF blocks.
11590 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
11591 does not support a non sign extended high 16 bits reloc. Adjusted

11623 * read.h: Define stringer here.
11624 * read.c, config/obj-ieee.c, config/obj-tcm88k.c: Not any of these

11635 Wed Mar 3 10:41:46 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
11637 Patches from Eric Youngdale:
11638 * make-gas.com: Find obstack.obj if it's not in the current
11639 directory.
11640 * read.c (s_ignore): Don't declare is_end_of_line. It's
11641 redundant, and triggers a VMS gcc compiler bug.
11643 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
11644 current segment as an argument. (Ignored in all cases but VMS.)
11645 All callers and definitions changed.
11647 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
11649 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING
11650 case compile again.

11654 * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,
11655 so "~0x80" won't be rejected.
11657 * config/obj-elf.c: No longer include elf/reloc.h.
11658 (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.

11662 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
11663 argument to s_ignore. Put "#if 0" around unused code.
11664 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
11665 Call elf_xstabs for .stabs and .xstabs operators.
11667 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
11669 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
11670 present.
11672 * configure.in: mips-bsd configuration was missing format spec.
11673 Should use aout.
11675 * Makefile.in (Makefile): Depends on configure.in.
11677 * config/tc-mips.c (append_insn): Don't check for alignment of
11678 frag in memory; alignment of instructions in section is a separate
11679 matter.
11681 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
11682 C availability.
11684 * listing.h: Always provide function declarations, not macros, so
11685 pcc won't lose.

11698 * config/tc-sparc.c (s_xword): Now call big_cons, so large
11699 constants are accepted, but symbolic values are not. GCC will not
11700 generate the latter currently.
11702 * frags.c (frag_init): New function.
11703 (zero_address_frag, bss_address_frag): Now initialized at run
11704 time.

11750 same as undefined symbols.
11751 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type
11752 bfd_reloc_code_real_type. Use seg_fix_{root,tail}P derived from
11753 section info.
11754 * write.h (fix_new): Update prototype.
11756 * tc.h (md_operand, md_convert_frag, tc_headers_hook,

11781 new section/subsection.
11783 * read.c: Don't include ctype.h.
11784 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
11785 for now; should be machine-dependent.

11943 (tc_aout_fix_to_chars): Array nbytes_r_length is now const.
11945 * config/tc-m68k.h (TC_COUNT_RELOC): Don't emit reloc if only
11946 offset field is set.
11948 Fri Jan 8 05:44:49 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

11955 * config/tc-sparc.c (architecture_requested, warn_on_bump,
11956 md_relax_table): Use default zero initialization.
11957 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
11958 latter, instead of selecting with preprocessor conditionals.
11960 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
11962 * configure.in: recognise all sparclite variants
11964 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
11966 * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --
11967 accidentally changed to use subseg_change where it should have
11968 been subseg_new.
11970 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
11972 * expr.c (operand): If character other than comma or newline is a
11973 logical end-of-line character, use the newline case.
11974 From Eric Youngdale:
11975 (operand): Set X_add_number field for floating-point numbers.
11976 (operand): Treat zero byte as end-of-operand.
11978 * configure.in (per-target): Look for with_bfd_assembler option.
11979 For now, only accept "no", until the merge is done.
11981 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
11982 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
11983 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
11984 * read.c: Finish conversion to S_* macros in the VMS only
11985 parts of the program. Add "const" modifier to hex_value.
11986 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
11987 "ifdef OBJ_VMS".
11988 * expr.c: Add "const" modifier to hex_value.
11989 * symbols.c: Finish conversion to S_* macros in the VMS only
11990 parts of the program. Add "const" modifier to
11991 md_[long,short]_jump_size. Remove declaration of const_flag
11992 (which will be declared in obj-vms.h).
11993 * write.c: Add "const" modifier to md_[long,short]_jump_size.
11994 Fix arguments to VMS_write_object_file.
11995 * config-gas.com: New file. Script for VMS systems to set up the
11996 configuration to build gas for VMS, and create config.status.
11997 * make-gas.com: Redone to work with new scheme.
11998 * config/obj-vms.c: Patch to fix bug where we were not correctly parsing the
11999 stabs directives.
12000 * config/obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
12001 will swap bytes if needed on a big endian system. Use throughout
12002 as needed.
12003 * config/obj-vms.c (obj_aout_stab): Add code to generate listing file.
12004 * config/obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
12005 types of malformed stabs. Change parsing algorithm so that we are
12006 more certain of having all of the information that we need on hand.
12007 * config/obj-vms.c (final_forward_reference): New function, used to help
12008 resolve the data types of as many struct elements as possible
12009 when some part of the struct is not fully defined by the compiler.
12010 * config/obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
12011 stabs directives.
12012 * config/obj-vms.c (VMS_write_object_file): Define all vtable psects
12013 as symbols as well in the object file. Look for external functions
12014 that start with "__vt.", and turn them into variables, since the
12015 g++ compiler is incapable of doing this.
12016 * config/tc-vax.c: Add '1' option for backward compatibility with older GCC
12017 versions.
12018 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
12019 * input-scrub.c (as_where): Fix bug where as would crash if we did not
12020 have the name of the source file yet.
12021 * config/ho-vms.h: define HO_VMS, not HO_VAX.
12023 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
12025 * read.c (s_data): Always use "data_section", since it'll map to
12026 SEG_DATA or SEG_E1 if needed.
12027 (s_lcomm): Likewise with bss_section.
12028 (s_fill): Use memset, not bzero.
12030 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
12032 * read.c: Deleted some code under "#ifdef DONTDEF" that was for
12033 handling GDB symbol table data.
12035 * config/obj-aout.h (segment_name): Delete definition.
12036 (seg_name): Delete declaration.

12043 * obj.h (obj_crawl_symbol_chain): Declare only if not
12044 BFD_ASSEMBLER.
12045 (obj_header_append, obj_pre_write_hook): Ditto.
12046 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
12047 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
12048 (segment_name) If BFD_ASSEMBLER, look up BFD section name;
12049 otherwise, use seg_name array.
12050 (seg_name): Declare only if not BFD_ASSEMBLER.
12051 (section_alignment): Declare only if not BFD_ASSEMBLER.
12052 (big_section, reg_section, pass1_section, diff_section,
12053 absent_section, text_section, data_section, bss_section): If
12054 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
12055 mapping to segT enum values.
12056 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
12057 if these are used or defined, if BFD_ASSEMBLER.
12058 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
12059 subseg_new split into two functions.
12060 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
12062 * as.h (volatile): Don't define if already defined.

12066 declare with format attribute for -Wformat checking.
12068 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
12070 * app.c, config/tc-*.c: Don't include read.h, since it is already
12071 included by as.h.
12073 * These are based on patches from Minh Tran-le
12074 <mtranle@paris.intellicorp.com>.
12075 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
12076 obj_format coffbfd and gas_target i386coff for target.
12077 (i[34]86-*-isc*): New host (uses sysv).
12078 * config/i386aix.mt: Removed (no longer used).
12079 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
12080 (MINUS_G): Removed.
12081 (LDFLAGS): Added, defined as -shlib.
12082 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
12083 * config/te-sco386.h (LOCAL_LABEL): Don't define.
12084 (DOT_LABEL_PREFIX): Define.
12085 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
12086 name rather than L0\001.
12087 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
12088 local_bss_counter.
12089 * symbols.c, symbols.h (local_bss_counter): Removed.
12090 * write.c (write_object_file): bss no longer uses
12091 local_bss_counter. Pass correct data and bss size to
12092 VMS_write_object_file.
12093 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
12094 argument, rather than using local_bss_counter.
12095 * config/tc-m88k.c (s_bss): Don't use local_bss_counter.
12096 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
12097 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
12098 (size_section): Restored sanity check.
12099 (do_relocs_for): Base section address on s_paddr rather than
12100 computing it. Adjust a29k R_IHIHALF special case to account for
12101 section paddr (used to require paddr to be zero). If there are no
12102 reclos, set s_relptr to 0. Set relocation size in object_headers.
12103 (fill_section): Always set s_vaddr here, removing
12104 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
12105 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
12106 Set STYP_INFO for .comment.
12107 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
12108 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
12109 (crawl_symbols): Handle 8 character section name correctly. Use
12110 H_{SET,GET}_* macros.
12111 (do_linenos_for): Set lineno size in object_headers.
12112 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
12113 set s_vaddr here. If string_byte_count remains 4, set it back to
12114 0, and only write strings out if there are some. Call
12115 fill_section before do_relocs_for and do_linenos_for.
12116 (obj_coff_section): Handle optional quoted second argument giving
12117 section characteristics.
12118 (obj_coff_bss): Added to handle .bss.
12119 (obj_coff_ident): Added to handle .ident (puts string in .comment
12120 section).
12121 (obj_coff_lcomm): Put common symbols in .bss, not .data.
12122 (fixup_mdeps): Change to segment. Call frag_wane after
12123 md_convert_frag.
12124 (fixup_segment): Explicitly check S_IS_COMMON before making 386
12125 adjustment (already happened only for common symbols, but this is
12126 clearer).
12127 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
12128 * config/tc-i386.c (s_bss): Don't use if I386COFF.
12129 (md_pseudo_table): Ignore .optim and .noopt.
12130 (tc_coff_sizemachdep): New function.
12131 * config/tc-i386.h (REVERSE_SORT_RELOCS): Undef, for SVR3
12132 compatibility.
12133 (LOCAL_LABEL): Removed definition.
12134 (DOT_LABEL_PREFIX): Defined.
12136 Mon Dec 28 10:32:05 1992 Ken Raeburn (raeburn@cygnus.com)
12138 * app.c (app_push): Use memcpy, not bcopy.
12139 (do_scrub_next_char): For \", return " not '.
12140 (symbol_chars): Now const.
12142 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
12143 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
12145 * config/obj-coff.h: Don't use #elif.
12147 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
12148 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
12150 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
12152 * write.c, config/obj-ieee.c: don't define SUB_SEGMENT_ALIGN
12153 if it is already defined.
12155 Tue Dec 15 12:40:11 1992 Steve Chamberlain (sac@thepub.cygnus.com)

12158 configured.
12160 * config/*z8k*: checkpoint
12162 Sun Dec 13 00:04:38 1992 Ian Lance Taylor (ian@cygnus.com)
12164 * read.c (read_a_source_file): avoid calling xmalloc (0).
12166 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
12168 * listing.c: Call xmalloc, not malloc; don't declare malloc.
12170 * Changes to support SCO 3.2v4:
12171 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
12172 SEG_BSS, fill with NOP_OPCODE.
12173 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
12174 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
12175 using ZERO_BASED_SEGMENTS.
12176 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
12177 never set segment address for SEG_E2 (.bss) and don't write out
12178 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
12179 (obj_coff_endef): Don't merge labels or symbols awaiting forward
12180 definitions, and don't merge tags with non-tags. Check for .bf
12181 rather than just checking whether the second character is b and
12182 the third character is f.
12183 (obj_coff_val): gcc can generate values which we don't handle
12184 correctly; discard information for now, since it only affects the
12185 debugging information.
12186 (tag_find_or_name): Don't insert tags in the symbol table.
12187 (yank_symbols): Don't merge labels.
12188 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
12189 already defined. Fill subsegments with NOP_OPCODE, not 0. Don't
12190 set segment address if ZERO_BASED_SEGMENTS.
12191 (obj_coff_section): Accept and ignore a trailing quoted string, as
12192 used in AT&T i386 syntax.
12193 (fixup_segment): Take segment as argument. On the i386, adjust PC
12194 relative addends by the segment vaddr.
12195 * config/tc-i386.h: Define SUB_SEGMENT_ALIGN.
12196 * config/tc-a29k.h: Define ZERO_BASED_SEGMENTS.
12197 * config/tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

12243 options. Updated options documentation for m68k. Some minor
12244 wording/punctuation changes.

12346 * subsegs.h: add extern to segment_info declaration.
12348 * read.h: added extern declarations for comment_chars,
12349 line_comment_chars, and line_separator_chars.
12350 read.c, app.c: removed definitions of comment_chars,

12353 * config/tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
12354 still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
12355 the register name.
12356 (insert_reg): put REGISTER_PREFIX before register names before
12357 putting them in the symbol table.

12362 section.
12364 * config/atof-ieee.c, config/atof-ns32k.c, config/tc-*.c: made
12365 EXP_CHARS, FLT_CHARS, comment_chars, line_comment_chars and
12366 line_seperator_chars consistently const, and always
12367 initialized them. Included read.h.
12369 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
12371 * config/tc-sparc.c (sparc_ip): Add code to flag error if an absolute
12372 constant will not fit in an immediate field.
12373 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
12375 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
12377 * config/obj-coff.c (callj_table): Delete global variable.
12378 (obj_emit_relocations): Define it locally here, and only if
12379 TC_I960 is defined.
12381 * config/tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.
12382 (m68k_ip): Don't warn about bignum used as float bit-pattern.
12384 * config/obj-coff.c: Replaced ANSI and non-ANSI function declarations
12385 with a single set using PARAMS macro.
12387 * config/tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length
12388 of 2.
12390 * config/tc-i960.c: Missed a couple of 0->NO_RELOC conversions.
12392 * config/tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
12393 so widening works consistently.
12395 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
12397 * version.c: Put conditional "const" before version_string, not
12398 before dummy function for VMS. Now version 1.91.03.
12400 * app.c (do_scrub_next_char): Need double-\ before `000' to show
12401 printed rep of null character.
12403 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
12405 * config/obj-coffbfd.c (write_object_file): check return value of
12406 bfd_close_all_done.
12408 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
12410 * Support for i386-sysv.
12411 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
12412 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
12413 be used to set them all to zero as was done before.
12414 (fill_section): segment addresses now set in write_object_file.
12415 (fill_section): Don't set STYP_NOLOAD for .bss section.
12416 (fixup_segment): 386 uses strange common symbol format.
12417 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
12418 compatibility with SVR3.2 linker.
12419 * configure.in: i386-sysv and i386-sco use coffbfd.
12421 * app.c (do_scrub_next_char): discard whitespace after a label.
12423 Sat Oct 10 12:33:45 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
12425 * configure.in: differentiate between SunOS 4 and Solaris2 for Sun4
12426 hosts, use the sysv configuration for solaris2

12440 * configure.in: recognize i386-*-bsd emulation.
12442 Thu Oct 1 23:05:12 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
12444 * configure.in: use the cpu-vendor-os triple for host and target
12446 Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com)

12453 * config/tc-i960.h, config/tc-i960.c: avoid the ANSI
12454 preprocessor addition #elif, since it is not supported by old
12455 compilers.
12456 config/ho-rs6000.h, config/tc-m68k.c: the native RS/6000
12457 compiler miscompiles a couple of expressions in tc-m68k.c.
12459 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
12461 * read.c (cons): If NO_RELOC is defined, use it.
12463 * config/tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
12465 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
12467 * config/tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
12468 local labels to start with a .) and set REGISTER_PREFIX to %.
12469 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
12471 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
12473 * messages.c: Comment changes.

12478 * messages.c: If __STDC__ is not defined, define NO_STDARG.
12480 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
12482 * listing.c (debugging_pseudo): Add stabs and stabn as things to
12483 ignore.
12485 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
12487 * config/obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
12488 sections starting from zero, rather than making them consecutive.
12489 This makes subsequent reloc calculations easier, esp if the object
12490 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
12491 allocate lcomm in .data rather than in .bss. It seems that some
12492 tools can't cope with a non-zero sized bss before linkage.
12494 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
12496 * config/tc-m68k.c: Replace "enum m68k_architecture" with "int"

12500 "-mno-688[58]1" options.
12502 * config/tc-m68k.c: Added CPU32 support.
12504 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
12506 * config/tc-m68k.c (m68k_ip): An(disp) is not pc relative.
12508 Tue Sep 15 17:25:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
12510 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
12511 Change LIBDEPS dependence to LIBS.
12513 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
12515 * Makefile.in (install): if $(tooldir) exists, install as in
12516 $(tooldir)/bin.
12518 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
12520 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
12521 .word is < -32768 or > 32767. The -J flag causes the error to be
12522 ignored. This is to catch over-sized switches generated by gcc on
12523 systems which don't support the broken .word hack.
12524 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
12525 write.c (fixup_segment): check for signed .word overflow if
12526 WARN_SIGNED_OVERFLOW_WORD.
12528 * write.c (fixup_segment): fixed missing parens in expression
12529 checking for byte or word overflow.
12531 * config/obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
12532 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
12533 WARN_SIGNED_OVERFLOW_WORD.
12535 * config/obj-coffbfd.c (fixup_segment): fixed missing parens in
12536 expression checking for byte or word overflow.
12538 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)
12540 Support for i386 coff
12541 * config/obj-coffbfd.h : added stuff
12542 * config/tc-i386.c (tc_coff_fix2rtype): new function
12543 * config/tc-i386.h : new coff defines
12545 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
12547 * input-scrub.c (input_scrub_push): call input_file_begin, not
12548 input_scrub_begin.
12549 messages.c (as_perror): print ": " between the passed in error and
12550 the strerror, like perror does.
12552 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
12554 * Makefile.in: use gas_target instead of modifying target_cpu.
12555 From Steve Chamberlain:
12556 Makefile.in: Handle m68*-*-coff*.
12557 read.c, read.h: add mult argument to s_space
12559 * config/tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
12560 Motorola and MIT syntax; gas can now assemble either type of
12561 file.
12562 * config/tc-m68kmote.c, config/tc-m68kmote.h: removed now
12563 superfluous files.
12565 From Steve Chamberlain:
12566 * config/m68kcoff.mt: for m68k COFF.
12567 * config/obj-coffbfd.c: (fixup_mdeps) added
12568 (size_section) removed bad sanity check
12569 (fill_section) added rs_machine_dependent case
12570 (write_object_file) call fixup_mdeps
12571 (fixup_segment) set fx_subsy to 0.
12572 * config/ obj-coffbfd.h: define WORKING_DOT_WORD (too hard to
12573 support) and handle m68k.
12574 * config/tc-m68k.c, config/tc-m68k.h: added m68k COFF support
12575 and Motorala pseudo ops.

12596 * Makefile.in (as.new): Depend on LOCAL_LOADLIBES.
12598 Fri Aug 28 16:25:22 1992 Ian Lance Taylor (ian@cygnus.com)
12600 * config/obj-bout.h, config/obj-bout.c (obj_header_append,
12601 obj_symbol_to_chars).
12602 * config/tc-i960.c (md_ri_to_chars): Always output bout object
12603 file in little endian byte order (used to use endianness of
12604 host).
12606 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
12608 * config/tc-m68k.c (init_table): Now const. Always include 68851
12609 data, so that "bc" is available to 68040 cache instructions.
12610 Added "tt0", "tt1", and 68ec030 variants.
12611 (md_assemble): Complain if 68000 (only) and 68881 are specified.
12612 (enum _register): Added TT0, TT1.
12613 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
12614 line number correctly in "internal error" messages. Don't print
12615 architecture-mismatch message for operand errors.
12617 From Colin Smith (colin@wrs.com):
12618 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
12619 than install_operand.

12623 * listing.c (buffer_line): rewind to the start of include
12624 files, they might be included twice.
12626 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
12628 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
12630 * Makefile.in: defined TARGET_CPU for C code so that it can choose
12631 one element of a family.
12633 * config/tc-m68k.c: use TARGET_CPU to choose default cpu type.
12635 * config/te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
12636 so that we can assemble hand-written libgcc code.
12638 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
12640 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
12641 has already been formatted (but may still contain %-characters).
12642 (as_bad): Likewise.
12644 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
12646 * config/tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
12647 written with indirection on the last two operands, which can be
12648 either data or address registers. Added a new operand type 'r'
12649 which accepts either register type. Added '(' to notend stuff in
12650 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
12652 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
12654 * as.h (enum _relax_state): Start off at one, not zero, to better
12655 catch uninitialized-variable errors.
12656 (linkrelax): Declare new variable.
12658 * messages.c (warning_count, error_count): Default initializer is
12659 sufficient.

12669 their not having symbols associated.
12671 * config/tc-i960.c (norelax, instrument_branches): Default initializer is
12672 sufficient.

12696 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
12697 being used with args swapped, causing occasional lossage when
12698 refilling buffers after an include file.
12700 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
12702 * messages.c (as_tsktsk): Use correct ANSI form for stdarg

12708 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
12709 selected architecture, print a message saying so and listing what

12724 Mon Aug 10 14:37:08 1992 Per Bothner (bothner@cygnus.com)
12726 * config/tc-m68k.c: ".align N" means align to N-byte boundary *only*
12727 if TN_SUN3; otherwise align to 2**N-byte bounary.
12729 Thu Aug 6 12:10:39 1992 Steve Chamberlain (sac@thepub.cygnus.com)
12731 * read.c (s_fill): make the .fill size clamped error a warn and
12732 fix bug where 0's were always placed.
12734 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
12735 two bytes of any constant with 0xff:
12737 Wed Aug 5 12:02:40 1992 Steve Chamberlain (sac@thepub.cygnus.com)
12739 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
12740 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.

12756 * expr.c (floating_constant): Separate "=-" to avoid confusing
12757 ancient or broken compilers.
12759 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
12760 processor/opcode mismatch, so reword the error message.
12761 (md_assemble): If no CPU has been set (even if FPU/PMMU
12762 characteristics have been), default to 68020. Don't need extra
12763 quotes around error string.
12765 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
12767 * read.c (potable): Revert sac's incorrect change made Jul 13.

12788 * read.c (potable): align should be nbytes, not ptwo!
12789 * write.c (write_object_file): extra glue for new bss attributes
12790 (relax_segment): SEG_BSS is ok now
12791 * config/tc-m68k.c (m68k_ip_op): can now parse more @( modes
12793 Mon Jul 6 17:09:32 1992 Steve Chamberlain (sac@cygnus.com)

12825 pcrel data stuff. (md_estimate_size_before_relax): when relaxing a
12826 68010 bxx into a bra+6 jmpxx, put the bytes of the jmp opcode into
12827 the right place. (s_bss): Don't put .bss stuff into SEG_DATA, put
12828 it into SEG_BSS

12833 * read.c(pseudo_set): register expressions can be the source of a
12834 set.
12835 * subsegs.c (subseg_new): Now -R forces all changes to SEG_DATA to
12836 goto SEG_TEXT (if a.out)
12837 * write.c (write_object_file): If a.out don't use the old way for
12838 -R.
12839 * config/obj-a.out (s_sect): complain if the user tries to use a

12861 * configure.in: Recognize sparclite as a sparc variant.
12863 * config/tc-sparc.c: Use new ARCHITECTURES_CONFLICT_P macro. Mention new
12864 -Asparclite flag.
12866 Tue May 26 16:47:56 1992 Steve Chamberlain (sac@thepub.cygnus.com)
12868 * config/tc-a29k.c: lint
12869 * listing.c, expr.c: patches from Andrew Smith
12871 Thu May 14 17:22:48 1992 K. Richard Pixley (rich@rtl.cygnus.com)

12888 * Makefile.in: do not print recursion lines.
12890 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)
12892 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
12894 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
12896 * write.c (write_object_file): For b.out format, round up section
12897 start addresses to match required alignment.
12899 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
12901 * Makefile.in (install): Install into $(tooldir)/bin, since that's
12902 where gcc looks for it.
12904 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
12906 * Makefile.in: Changed some lines to be less confusing for some
12907 makes.

12920 * Makefile.in: install the man page.
12922 * Makefile.in: pass down MAKEINFO explicitly on info.

12928 * flonum-const.c: renamed flonum-konst.c to stop dos name
12929 conflict.
12931 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
12933 * config/tc-m68k.h, config/te-sun3.h: moved LOCAL_LABELS_FB
12934 definition from tc-m68k.h to te-sun3.h.
12936 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
12938 * configure.in: vxworks68 gets te-sun3.h.
12940 * expr.c: remove limitation that local_labels_dollar or
12941 local_labels_fb must be < 10.
12943 * symbols.c: remove local_labels_dollar, replace with a function
12944 interface for a sparse array. All users adjusted.
12946 * config/te-sun3.h: add LOCAL_LABELS_DOLLAR.
12948 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
12950 * doc/Makefile.in: commented out line for building as-all.texinfo.
12951 This is temporary.
12953 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
12955 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
12957 * Makefile.in: added check target.
12959 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
12961 * Makefile.in: added tooldir and program_prefix.
12963 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)

12967 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
12969 * Makefile.in (strerror.o): Add rule so that broken Sun make can
12970 work in subdirs.
12972 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
12974 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
12976 * expr.c (operand): if can't work out what sort of operand it is,
12977 then look through FLT_CHARS for a hint.
12979 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
12981 * Makefile.in, configure.in: removed traces of namesubdir,
12982 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
12983 copyrights to '92, changed some from Cygnus to FSF.
12985 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
12986 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
12987 copyrights to '92, changed some from Cygnus to FSF.
12989 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
12991 * expr.c: If an expression is single comma, then return with
12992 SEG_ABSENT rather than an error - since the sparc front end does
12993 really strange things with things like fbge,a
12995 * as.h: include bfd.h if using many sections
12996 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
12997 local labels didn't work.
12998 * listing.c (list_symbol_table): don't core dump when there's no
12999 symbol there.
13000 * write.c, write.h: call fix_new with the right number of args on
13001 the H8.
13002 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
13003 errors nices
13005 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
13007 * app.c: MRI compatibility - allow single quote to start a string.
13008 * as.c: fix typo recently introduced.
13009 * as.h : Don't include aout/reloc.h - it's not right for COFF!
13010 * expr.c: Much rewriting, to accomodate MRI syntax for
13011 expressions. Also easier to read now.
13012 * listing.c: Put back defuns
13013 * read.c: modified to accept MRI syntax, put back listing pseudo
13014 ops so that an assembler built with NO_LISTING ignores list ops
13015 rather than pukes.
13016 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
13017 machine is a SPARC or a 29K.
13018 * config/obj-aout.c: added s_sect pseudo op
13019 * config/obj-coffbfd.c: lints, set the filehdr flags right and
13020 fill in the timestamp.
13021 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
13022 anymore, define all the relocs which the tc-<x> bit will use so we
13023 can translate from them to the coff types.
13024 * config/tc-a29k.c: reloc_type isn't ane enum any more
13025 * config/tc-m68k.c: Added NO_RELOC definition.
13027 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
13029 * Makefile.in: put header files before C source for TAGS; remove
13030 references to non-existent syscalls.h.
13032 * read.c, write.c subsegs.c: back out the .bss changes.
13034 * config/obj-aout.c: do not include stab.gnu.h if NO_LISTING.
13036 * config/tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
13038 * a.out.h: removed.
13040 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
13042 * symbols.c (local_label_name): symbols now start with ^A.
13044 * read.c, subsegs.c, write.c obj-coff.c: added handling of
13045 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
13046 generate these sections. .align: will use NOP_OPCODE or 0
13047 for padding. This is just for being nice to the
13048 disassembler.
13050 * expr.c (operand): changed to generate local label "\001L0"
13051 starting with a ^A so that it is recognized as a local label.
13053 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
13055 * config/tc-i386.c: tc-i386.c: added handling of the following opcodes:
13056 i/o opcodes - inb, inw, outb and outw. string manipulation with
13057 att syntax - scmp, slod, smov, ssca, ssto.
13059 * config/obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
13060 to just after .file .
13062 In obj_crawl_symbol_chain() where it tries to put the external
13063 symbols apart, with the condition:
13064 (!S_IS_DEFINED(symbolP) &&
13065 !S_IS_DEBUG(symbolP) &&
13066 !SF_GET_STATICS(symbolP))
13067 it was moving too many symbols out. So I switch it back to the
13068 condition:
13069 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
13071 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
13072 so that we don't use the F_RELFLG which make the linker complain
13073 that somebody has stripped the relocation info.
13075 Also, the AIX ld program require that the relocation table
13076 is sorted by r_vaddr like the standard ATT assembler does.
13078 [he also changed the sizeof(struct ...)'s into the coff
13079 style FOOSZ macros. I'm not sure this is right, but I can't
13080 remember why. xoxorich.]
13082 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
13084 * Makefile.in, configure.in, doc: use the doc. Build it, install
13085 it, clean it, etc.
13087 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
13089 * read.c: white space and comments only.
13091 * configure.in: use the new atof-ns32.c for ns32k.
13093 * write.c: comment change only.
13095 * config/tc-m88k.[hc]: pulled in from hack's unfinished work. These
13096 aren't yet integrated.
13098 * config/tc-i860.[hc]: blew off the dust. Something must still be done
13099 about conflicting relocation types.
13101 * config/tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
13102 real thing.
13104 * config/tc-i960.c, config/tc-sparc.c: white space and comments only.
13106 * config/tc-a29k.h: delete duplicate macro definition.
13108 * new file atof-ns32k.c copied from hack's last unreleased gas.
13110 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
13112 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
13113 rather than abort.
13115 * nearly everything. flush ChangeLog, package as gas-1.92.1.
13116 ChangeLog's prior to this are sketchy at best. I have logs.
13117 They just aren't ChangeLogs.
