3 * config/tc-mips.c (RDATA_SECTION_NAME): Define.
4 (macro): Correct M_LI_SS SVR4_PIC/EMBEDDED_PIC case. After M_LI_D
5 or M_L_DOB or label dob, force a new frag to avoid getting
6 confused in tc_gen_reloc.

8 (s_change_sec): Likewise.
10 Fri Jun 3 23:35:36 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
12 * read.c (emit_expr): Use memset to zero out memory, rather than
13 going through md_number_to_chars. This permits handling symbolic
14 arguments when the size is larger than sizeof (valueT), if
15 TC_CONS_FIX_NEW is prepared to handle the case (as it is on MIPS).
17 Fri Jun 3 12:50:13 1994 David J. MacKenzie (djm@rtl.cygnus.com)

45 md_parse_option. Remove md_parse_long_option.
46 * config/tc-ns32k.c: Rename `struct option' to `struct ns32k_option'.
47 * config/tc-i386.h: Don't define md_parse_option.

67 (control_regs): New pointer.
68 (m68k_ip): Use control_regs instead of testing CPU every time.

72 m68851 choice. Set control_regs.
73 (md_parse_option): Handle "68060".
74 * configure.in: Setting cpu_type, recognize m68060 too.
76 * config/obj-coff.c (fixup_segment) [!BFD_ASSEMBLER]

108 Fri May 27 10:05:53 1994 Ken Raeburn (raeburn@cygnus.com)
110 Merged in changes from gas-2.3 net release:

137 new VMS symbol-type macros; signed and unsigned quadword integers,
138 for `long long' support. Their values come from the existing
139 DSC$K_DTYPE_QU and DSC$K_DTYPE_Q macros in <descrip.h>. The
140 VMS debugger now recognizes `long long' variables correctly.
141 config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
142 for gcc2's predefined types "long double" (same as double, as
143 per gcc's current state), "long long int", "long long unsigned
144 int", and final `otherwise' case (to avoid uninitialized type
145 and size fields). [caveat: predefined types "complex int",
146 "complex float", "complex double", and "complex long double" are
149 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
150 of 0, because the latter indicates success rather than failure

156 allocating new symbol entry and linking it to VMS_Symbol_type_list.
158 Tue May 17 20:47:31 1994 Pat Rankin (rankin@eql.caltech.edu)
160 * config/obj-vms.c (Write_VMS_MHD_Records): don't try to interpret
161 the contents of the GAS_VERSION string when falling back to it for
162 language processor identification.
164 * make-gas.com, vmsconf.sh (ENVIRON): fix misspelling of
165 `psect_attr' in linker options.

193 * config/tc-hppa.c (pa_parse_fp_cmp_cond): Report an error
194 on a partial completer match.

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

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

620 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
621 flag rather than signedp field. Only permit extended range if
622 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
623 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
625 * config/tc-ppc.c (ppc_size): New static variable.
626 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
627 (md_begin): If an instruction has a size specific flag set, only

630 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
632 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
633 cross section PC relative relocs right for COFF and ELF.
635 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
637 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

648 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
649 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
650 and -many (all architectures).

660 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
661 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
663 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
664 branch with an instruction that uses $at, in case the branch is
666 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
667 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
668 to make it pcrel_offset.
669 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
670 reloc->address; another gruesome hack to get gas reloc handling to
673 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
675 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using

679 (md_assemble): Call it.
680 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
682 (lituse_pending): New variable. Set by anything that generates a
683 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
684 tested by code that might want to emit a LITUSE reloc.
685 (emit_unaligned_io): New function. Currently calls md_assemble,
686 but it should eventually be converted to generate the insn itself
687 and call emit_insn directly.
688 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
689 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
690 emit_bis_r): Likewise.

697 the value can't be resolved.
699 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
701 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
702 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

717 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
718 (load_address): Handle EMBEDDED_PIC.
719 (macro): Handle EMBEDDED_PIC in all PIC cases.
720 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
721 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
722 -non_shared to use NO_PIC (this is how the Irix 5 assembler
723 works). Do not permit -G with SVR4_PIC.
724 (s_abicalls): Warn if -G was used, and force -G 0.
725 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
726 anything but a.out, not just for ELF. For ECOFF, don't generate a
727 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
729 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
731 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

737 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
739 * Makefile.in (config-stamp): If `defs' is defined, emit a
740 preprocessor directive to create a macro named by this value into
741 config.new; don't explicitly go for BFD_ASSEMBLER.
742 * configure.in: Define `defs', not `BFDDEF'. Set it to
743 MANY_SEGMENTS for any obj-coffbfd target.
744 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
745 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
747 (LOCAL_LOADLIBES): Deleted.
748 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
749 * config/m88kcoff.mt (TDEFINES): Ditto.

775 bfd_set_symtab is called.
776 (dump_section_relocs): Note whether a symbol is a section symbol
778 (adjust_reloc_syms): For now, always supply an absolute symbol for
779 fixups without symbols but not yet `done'. Use section_symbol to
780 get the symbol, instead of going directly for abs_symbol.
781 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
782 reloc is not a section symbol and is not in the symbol table.
783 (set_symtab): New function, broken out from write_object_file.
784 Counts symbol table instead of relying on an earlier count.
785 (write_object_file): Call set_symtab, but do it after potentially
786 invoking the *_frob_file macros. Don't bother counting symbols.
787 Call symbol_remove, instead of expanding it in place. Moved the
788 conditionalized `object_file_size' declaration down to
789 conditionalized block where it's used. When using the absolute
790 symbol for a fixup without a symbol, set sy_used_in_reloc.
791 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
792 the correct symbol for the absolute section.
794 * subsegs.c (section_symbol): Use symbol_new instead of
795 symbol_make, since we may want it to go into the symbol table.
796 Make the new symbol have internal linkage. If
797 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
798 symbol with the newly created GAS symbol.
799 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
800 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

805 (in_signed_range): New function.
807 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
808 (sparc_ip, label "immediate"): Reject constants for pcrel
809 instructions only if the relocation type indicates a "call"
810 instruction and the offset is within range of a "jmpl %g0". If
811 it's not in range, use the absolute section symbol plus an offset.
812 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
814 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
816 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
819 * configure.in: Eliminated all targets using obj-coff but not
820 defining BFD_ASSEMBLER; I think all such targets that are
821 supported will be matched by real CPU-OS combinations earlier in
823 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
824 some comments about the dpx2 configuration, but left it disabled,
825 since it couldn't be reached before.
826 (target a29k-amd-ebmonold): Deleted.
828 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
830 * config/tc-hppa.c (pa_import): Correctly handle importing of an

836 the 'j' operand if there are no further alternatives for this
839 * config/obj-coffbfd.c (adjust_stab_section): Initialize
840 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
841 is not SEG_UNKNOWN rather than checking whether it is >= 0.
843 * config/tc-mips.c (mips_align): Take new argument, label, and use
844 it instead of global insn_label.
845 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
846 call to mips_emit_delay and pass it to mips_align.
848 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
850 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
852 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
853 argument to a .callinfo directive. Don't loop forever on errors.
855 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
856 use pre-defined registers as arguments.

860 * write.c (write_object_file): Check both S_IS_LOCAL and
861 S_IS_EXTERNAL when deciding whether to discard a symbol.
863 * config-gas.com: Scan Makefile.in, not version.c, for current
864 version number. Delete all versions of temp files when finished
865 with them. Create config.h.
867 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
868 values to reduce number of lookups with S_GET_VALUE. Skip debug

870 holger@botbso.rhein-main.de.)
871 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
872 field. (Also from Holger Teutsch.) Watch for a would-be register
873 mask that spans frags.
875 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
876 this_base, not line_base. (Patch from Andreas Arens,
877 ari@obelix.av.rwth-aachen.de.)
879 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
880 look local if they're exported or undefined. Used to be done for
883 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
884 Get it from the looked-up symbol, instead of using the string from
885 the input stream, which is no longer null-terminated.
886 (LEX_PCT): New macro, defaults to 0.
887 (lex_type): Use it for `%'.
889 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
890 (vip_op): Now static, and returns void. Callers changed. Added
892 (vip): Ditto. Call as_fatal directly if a program bug is

950 (obj_coff_section): Declare.
951 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
952 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

954 silently compiling to do nothing.
955 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define only if
957 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

2670 pass new argument for i, j and o cases.

2892 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2893 the table, require that the one without bit 0x1000000 set come
2894 first. Require further that it be case 'b' or 'P'. The a29k
2895 opcode table already meets these constraints.
2896 (machine_ip): When handling case 'i' or 'A', make sure that the

2948 * write.c (write_relocs): For relocs that are pc_relative and
2949 pcrel_offset and not partial_inplace, adjust reloc->addend to

3005 for keeping or rejecting configurations still under development;
3006 default is to assume production environment, and reject configs
3007 still being worked on. Mark Elf configurations (except sparc and
3008 i386) as developmental. Deleted cases matching some generic names
3009 in favor of more specific names. (E.g., when we get Alpha

3026 through inclusion of tc-hppa.h. Delete all forward declarations
3027 for functions only used within tc-hppa.c, likewise for structures,
3028 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
3029 conditional code in a few small places.
3031 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3032 structures, global variables, forward declarations together.

3034 conditional code -- try to group conditional code together
3035 into a few places. Make all functions and variables which
3036 are only used within tc-hppa.c static. PARAMize all functions.
3037 Add comments to functions. Delete unused functions, variables,
3038 #defines, etc. Delete unused members within structures. Delete
3039 ldil;ble hacks -- it is believed they were installed to work
3040 around old gas bugs. Avoid using mixed case for local
3041 functions, variables, and structures. Fix formatting problems
3042 not found by GNU-indent. Add FIXME notices for things which
3043 should be worked on the near future. Delete lots of old
3044 useless (1.36 PA-SOM) code.

3061 * config/tc-hppa.c: Likewise.
3063 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
3064 of elf32_symbol_type.
3065 (pa_export_args): Likewise.
3066 (elf_hppa_final_processing): Likewise.

3072 * config/tc-hppa.c: (md_section_align): Align all sections to
3073 a multiple of the section alignment rather than always a
3076 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
3077 bits are zero (eg they specify no relocations), then do not even
3078 bother adding their entries to thesymextn section.

3117 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3119 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3120 ELF, since the ELF object format does not have these type of
3121 relocations. Change the abort into as as_bad and return
3122 BFD_RELOC_NONE to silence compiler warnings.
3123 (md_assemble): Keep track of the instruction size. Allow white
3124 space between the $ and the constant for compatibility with older
3125 gases and other assemblers.
3126 (i386_operand): Skip spaces between $ and expression.
3127 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

5637 prototypes for all static functions. Moved existing minimal
5638 debugging format support info #ifndef OBJ_ECOFF blocks.

5687 * make-gas.com: Find obstack.obj if it's not in the current
5689 * read.c (s_ignore): Don't declare is_end_of_line. It's
5690 redundant, and triggers a VMS gcc compiler bug.
5692 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5693 current segment as an argument. (Ignored in all cases but VMS.)
5694 All callers and definitions changed.

6011 (operand): Treat zero byte as end-of-operand.
6013 * configure.in (per-target): Look for with_bfd_assembler option.
6014 For now, only accept "no", until the merge is done.
6016 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
6017 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

6019 * read.c: Finish conversion to S_* macros in the VMS only
6020 parts of the program. Add "const" modifier to hex_value.
6021 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
6023 * expr.c: Add "const" modifier to hex_value.
6024 * symbols.c: Finish conversion to S_* macros in the VMS only
6025 parts of the program. Add "const" modifier to
6026 md_[long,short]_jump_size. Remove declaration of const_flag
6027 (which will be declared in obj-vms.h).
6028 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6029 Fix arguments to VMS_write_object_file.
6030 * config-gas.com: New file. Script for VMS systems to set up the
6031 configuration to build gas for VMS, and create config.status.

6039 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6040 types of malformed stabs. Change parsing algorithm so that we are

6047 * obj-vms.c (VMS_write_object_file): Define all vtable psects
6048 as symbols as well in the object file. Look for external functions

6050 g++ compiler is incapable of doing this.
6051 * tc-vax.c: Add '1' option for backward compatibility with older GCC
6053 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

6062 (s_lcomm): Likewise with bss_section.
6063 (s_fill): Use memset, not bzero.
6065 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

6089 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
6090 mapping to segT enum values.
6091 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
6092 if these are used or defined, if BFD_ASSEMBLER.
6093 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6094 subseg_new split into two functions.
6095 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6097 * as.h (volatile): Don't define if already defined.
6098 (had_errors, had_warnings): Provide prototypes for ANSI C even if
6100 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
6101 declare with format attribute for -Wformat checking.
6103 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
6105 * app.c, config/tc-*.c: Don't include read.h, since it is already
6108 * These are based on patches from Minh Tran-le
6109 <mtranle@paris.intellicorp.com>.
6110 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
6111 obj_format coffbfd and gas_target i386coff for target.
6112 (i[34]86-*-isc*): New host (uses sysv).
6113 * config/i386aix.mt: Removed (no longer used).
6114 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
6116 (LDFLAGS): Added, defined as -shlib.
6117 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
6118 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6119 (DOT_LABEL_PREFIX): Define.
6120 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
6121 name rather than L0\001.
6122 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
6124 * symbols.c, symbols.h (local_bss_counter): Removed.
6125 * write.c (write_object_file): bss no longer uses
6126 local_bss_counter. Pass correct data and bss size to
6127 VMS_write_object_file.

6131 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
6132 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
6133 (size_section): Restored sanity check.
6134 (do_relocs_for): Base section address on s_paddr rather than
6135 computing it. Adjust a29k R_IHIHALF special case to account for
6136 section paddr (used to require paddr to be zero). If there are no
6137 reclos, set s_relptr to 0. Set relocation size in object_headers.
6138 (fill_section): Always set s_vaddr here, removing
6139 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6140 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6141 Set STYP_INFO for .comment.
6142 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
6143 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

6145 H_{SET,GET}_* macros.
6146 (do_linenos_for): Set lineno size in object_headers.
6147 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6148 set s_vaddr here. If string_byte_count remains 4, set it back to
6149 0, and only write strings out if there are some. Call
6150 fill_section before do_relocs_for and do_linenos_for.
6151 (obj_coff_section): Handle optional quoted second argument giving
6152 section characteristics.
6153 (obj_coff_bss): Added to handle .bss.
6154 (obj_coff_ident): Added to handle .ident (puts string in .comment
6156 (obj_coff_lcomm): Put common symbols in .bss, not .data.
6157 (fixup_mdeps): Change to segment. Call frag_wane after
6159 (fixup_segment): Explicitly check S_IS_COMMON before making 386
6160 adjustment (already happened only for common symbols, but this is
6162 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
6163 * config/tc-i386.c (s_bss): Don't use if I386COFF.

6174 (do_scrub_next_char): For \", return " not '.
6175 (symbol_chars): Now const.
6177 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6178 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6180 * config/obj-coff.h: Don't use #elif.
6182 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6183 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

6209 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6210 using ZERO_BASED_SEGMENTS.
6211 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6212 never set segment address for SEG_E2 (.bss) and don't write out
6213 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6214 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6215 definitions, and don't merge tags with non-tags. Check for .bf
6216 rather than just checking whether the second character is b and
6217 the third character is f.
6218 (obj_coff_val): gcc can generate values which we don't handle
6219 correctly; discard information for now, since it only affects the
6220 debugging information.
6221 (tag_find_or_name): Don't insert tags in the symbol table.
6222 (yank_symbols): Don't merge labels.
6223 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6226 (obj_coff_section): Accept and ignore a trailing quoted string, as
6227 used in AT&T i386 syntax.
6228 (fixup_segment): Take segment as argument. On the i386, adjust PC
6229 relative addends by the segment vaddr.
6230 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
6231 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

6368 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
6369 could be doing emulation.
6371 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6374 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
6377 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
6379 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

6403 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6405 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6406 constant will not fit in an immediate field.
6407 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
6409 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

6442 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6444 * Support for i386-sysv.
6445 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6469 * tc-m68k.c (get_num): make it work for all segments, not just the
6472 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
6474 * configure.in: recognize i386-*-bsd emulation.

6483 * tc-z8k.c: lots of bug fixes
6485 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6487 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6488 #elif, since it is not supported by old compilers.
6489 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6490 couple of expressions in tc-m68k.c.
6492 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6494 * read.c (cons): If NO_RELOC is defined, use it.
6496 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6498 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6500 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6501 local labels to start with a .) and set REGISTER_PREFIX to %.
6502 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6504 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
6506 * messages.c: Comment changes.
6508 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

6511 * messages.c: If __STDC__ is not defined, define NO_STDARG.
6513 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
6515 * listing.c (debugging_pseudo): Add stabs and stabn as things to
6518 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6520 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6521 sections starting from zero, rather than making them consecutive.
6522 This makes subsequent reloc calculations easier, esp if the object
6523 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6524 allocate lcomm in .data rather than in .bss. It seems that some
6525 tools can't cope with a non-zero sized bss before linkage.
6527 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6529 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6530 throughout. That enum no longer means what we thought it meant.
6532 * tc-m68k.c (md_assemble, md_parse_option): Handle new
6533 "-mno-688[58]1" options.
6535 * tc-m68k.c: Added CPU32 support.
6537 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

6543 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
6544 Change LIBDEPS dependence to LIBS.
6546 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6548 * Makefile.in (install): if $(tooldir) exists, install as in
6551 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6553 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6554 .word is < -32768 or > 32767. The -J flag causes the error to be
6555 ignored. This is to catch over-sized switches generated by gcc on
6556 systems which don't support the broken .word hack.
6557 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6558 write.c (fixup_segment): check for signed .word overflow if
6559 WARN_SIGNED_OVERFLOW_WORD.
6561 * write.c (fixup_segment): fixed missing parens in expression
6562 checking for byte or word overflow.
6564 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
6565 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
6566 WARN_SIGNED_OVERFLOW_WORD.

6569 expression checking for byte or word overflow.
6571 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6573 Support for i386 coff
6574 * obj-coffbfd.h : added stuff
6575 * tc-i386.c (tc_coff_fix2rtype): new function

7018 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7020 * expr.c: If an expression is single comma, then return with
7021 SEG_ABSENT rather than an error - since the sparc front end does
7022 really strange things with things like fbge,a
7024 * as.h: include bfd.h if using many sections
7025 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
7026 local labels didn't work.
7027 * listing.c (list_symbol_table): don't core dump when there's no
7029 * write.c, write.h: call fix_new with the right number of args on
7031 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
7034 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7036 * app.c: MRI compatibility - allow single quote to start a string.
7037 * as.c: fix typo recently introduced.
7038 * as.h : Don't include aout/reloc.h - it's not right for COFF!
7039 * expr.c: Much rewriting, to accomodate MRI syntax for
7040 expressions. Also easier to read now.
7041 * listing.c: Put back defuns
7042 * read.c: modified to accept MRI syntax, put back listing pseudo
7043 ops so that an assembler built with NO_LISTING ignores list ops
7045 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7046 machine is a SPARC or a 29K.
7047 * config/obj-aout.c: added s_sect pseudo op
7048 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7049 fill in the timestamp.
7050 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7051 anymore, define all the relocs which the tc-<x> bit will use so we
7052 can translate from them to the coff types.
7053 * config/tc-a29k.c: reloc_type isn't ane enum any more
7054 * config/tc-m68k.c: Added NO_RELOC definition.

7069 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7071 * symbols.c (local_label_name): symbols now start with ^A.
7073 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7074 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7075 generate these sections. .align: will use NOP_OPCODE or 0
7076 for padding. This is just for being nice to the
7079 * expr.c (operand): changed to generate local label "\001L0"
7080 starting with a ^A so that it is recognized as a local label.
7082 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7084 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7085 i/o opcodes - inb, inw, outb and outw. string manipulation with
7086 att syntax - scmp, slod, smov, ssca, ssto.
7088 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7089 to just after .file .
7091 In obj_crawl_symbol_chain() where it tries to put the external
7092 symbols apart, with the condition:
7093 (!S_IS_DEFINED(symbolP) &&
7094 !S_IS_DEBUG(symbolP) &&
7095 !SF_GET_STATICS(symbolP))
7096 it was moving too many symbols out. So I switch it back to the
7098 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7100 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7101 so that we don't use the F_RELFLG which make the linker complain
7102 that somebody has stripped the relocation info.
7104 Also, the AIX ld program require that the relocation table
7105 is sorted by r_vaddr like the standard ATT assembler does.
7107 [he also changed the sizeof(struct ...)'s into the coff
7108 style FOOSZ macros. I'm not sure this is right, but I can't
7109 remember why. xoxorich.]

7113 * Makefile.in, configure.in, doc: use the doc. Build it, install
7116 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
7118 * read.c: white space and comments only.
7120 * configure.in: use the new atof-ns32.c for ns32k.
7122 * write.c: comment change only.
7124 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7125 aren't yet integrated.
7127 * tc-i860.[hc]: blew off the dust. Something must still be done
7128 about conflicting relocation types.
7130 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7133 * tc-i960.c, tc-sparc.c: white space and comments only.
7135 * tc-a29k.h: delete duplicate macro definition.
7137 * new file atof-ns32k.c copied from hack's last unreleased gas.
7139 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7141 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7144 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7145 ChangeLog's prior to this are sketchy at best. I have logs.
7146 They just aren't ChangeLogs.
