1 Wed Jun 15 12:32:55 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3 * config/tc-mips.c (mips_ip): Permit a modifier in 'o' case, and
4 permit non constant expressions in 'u' case. Lets ``lui
5 $8,%hi(foo); lw $8,%lo(foo)($8)'' work correctly.
7 Mon Jun 13 12:08:52 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

34 Wed Jun 8 06:28:37 1994 Bill Cox (bill@cygnus.com)
36 * Makefile.in (check): Delete as.new dependency, so that

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

109 m68040_control_regs, m68060_control_regs): New arrays.
110 (control_regs): New pointer.
111 (m68k_ip): Use control_regs instead of testing CPU every time.
112 Use last_movec_reg too. In error messages, handle 68060, and
113 print 68060 for mfloat, too.
114 (m68k_init_after_args): Handle "68060". Use m68040up for making
115 m68851 choice. Set control_regs.
116 (md_parse_option): Handle "68060".
117 * configure.in: Setting cpu_type, recognize m68060 too.
119 * config/obj-coff.c (fixup_segment) [!BFD_ASSEMBLER]

121 if pcrel is already set.
123 * read.c (potable): Add this_gcc_requires_the_gnu_assembler in all
124 lower-case, in case we're ignoring case of opcodes in the input

180 new VMS symbol-type macros; signed and unsigned quadword integers,
181 for `long long' support. Their values come from the existing
182 DSC$K_DTYPE_QU and DSC$K_DTYPE_Q macros in <descrip.h>. The
183 VMS debugger now recognizes `long long' variables correctly.
184 config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
185 for gcc2's predefined types "long double" (same as double, as
186 per gcc's current state), "long long int", "long long unsigned
187 int", and final `otherwise' case (to avoid uninitialized type
188 and size fields). [caveat: predefined types "complex int",
189 "complex float", "complex double", and "complex long double" are
192 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead

201 Tue May 17 20:47:31 1994 Pat Rankin (rankin@eql.caltech.edu)
203 * config/obj-vms.c (Write_VMS_MHD_Records): don't try to interpret
204 the contents of the GAS_VERSION string when falling back to it for
205 language processor identification.
207 * make-gas.com, vmsconf.sh (ENVIRON): fix misspelling of
208 `psect_attr' in linker options.

231 * config/tc-hppa.c (pa_ip): Use R_HPPA_ABS_CALL, not R_HPPA for
234 Tue May 17 12:50:46 1994 Jeff Law (law@snake.cs.utah.edu)
236 * config/tc-hppa.c (pa_parse_fp_cmp_cond): Report an error

547 * expr.c (operand): Try to parse "0f" and "0b" sequences as
548 floating point and binary numbers respectively; if it doesn't
549 work, treat them as local labels.

578 argument, the reloc type.
579 (load_register): Pass reloc type to macro_build for 'u'.
580 (macro): Likewise. For M_LA_AB permit a difference expression
581 when generating embedded PIC code between an arbitrary symbol and
582 a symbol in the .text section.

584 BFD_RELOC_PCREL_LO16 to be emitted.
585 (md_apply_fix): Check that most relocs are not PC relative.
586 Handle BFD_RELOC_PCREL_HI16_S and BFD_RELOC_PCREL_LO16.

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

643 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
644 value into the file if the fixup will not generate a reloc.
646 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
648 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
649 don't spew remainder of input file in error message.
650 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
651 message with reloc type and try to process remainder of file.
653 * doc/Makefile.in (install-info-as, install-info-gasp): New
654 targets, now explicitly checking $(srcdir) for info files.
655 (install-info): Depend on both of them; do nothing more.
657 Mon Apr 4 17:06:04 1994 Jeffrey A. Law (law@cygnus.com)
659 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
661 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
663 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
664 flag rather than signedp field. Only permit extended range if
665 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
666 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
668 * config/tc-ppc.c (ppc_size): New static variable.
669 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
670 (md_begin): If an instruction has a size specific flag set, only
671 add it if we are assembling that size.
673 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
675 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
676 cross section PC relative relocs right for COFF and ELF.
678 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
680 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
681 (OBJ_PROCESS_STAB): Don't define.
683 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
685 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
686 the type of symbol set symbols which happen to be in the absolute
687 or undefined section.
689 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
691 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
692 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
693 and -many (all architectures).
695 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

703 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
704 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
706 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
707 branch with an instruction that uses $at, in case the branch is
709 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
710 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
711 to make it pcrel_offset.
712 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
713 reloc->address; another gruesome hack to get gas reloc handling to
716 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
718 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
721 (emit_insn): New function.
722 (md_assemble): Call it.
723 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
725 (lituse_pending): New variable. Set by anything that generates a
726 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
727 tested by code that might want to emit a LITUSE reloc.
728 (emit_unaligned_io): New function. Currently calls md_assemble,
729 but it should eventually be converted to generate the insn itself
730 and call emit_insn directly.
731 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
732 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
733 emit_bis_r): Likewise.

740 the value can't be resolved.
742 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
744 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
745 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
746 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
748 (mips_force_relocation): New function.
749 (md_apply_fix): Set fixP->fx_done appropriately.

758 * config/tc-mips.c (enum mips_pic_level): New enum.
759 (mips_pic): Change from int to enum mips_pic_level. Change all
760 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
761 (load_address): Handle EMBEDDED_PIC.
762 (macro): Handle EMBEDDED_PIC in all PIC cases.
763 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
764 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
765 -non_shared to use NO_PIC (this is how the Irix 5 assembler
766 works). Do not permit -G with SVR4_PIC.
767 (s_abicalls): Warn if -G was used, and force -G 0.
768 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
769 anything but a.out, not just for ELF. For ECOFF, don't generate a
770 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
772 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
774 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
776 * config/tc-hppa.c (create_new_space): Use ints, not chars as
777 parameters to avoid losing when compiling with HP CC.

780 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
782 * Makefile.in (config-stamp): If `defs' is defined, emit a
783 preprocessor directive to create a macro named by this value into
784 config.new; don't explicitly go for BFD_ASSEMBLER.
785 * configure.in: Define `defs', not `BFDDEF'. Set it to
786 MANY_SEGMENTS for any obj-coffbfd target.
787 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
788 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
790 (LOCAL_LOADLIBES): Deleted.
791 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
792 * config/m88kcoff.mt (TDEFINES): Ditto.
793 * config/ebmon29k.mt: Deleted.
794 * config/h8300hds.mt: Deleted.
795 * config/ic960coff.mt: Deleted.
796 * config/sparc.mt: Deleted.
797 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
798 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
799 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

818 bfd_set_symtab is called.
819 (dump_section_relocs): Note whether a symbol is a section symbol
821 (adjust_reloc_syms): For now, always supply an absolute symbol for
822 fixups without symbols but not yet `done'. Use section_symbol to
823 get the symbol, instead of going directly for abs_symbol.
824 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
825 reloc is not a section symbol and is not in the symbol table.
826 (set_symtab): New function, broken out from write_object_file.
827 Counts symbol table instead of relying on an earlier count.
828 (write_object_file): Call set_symtab, but do it after potentially
829 invoking the *_frob_file macros. Don't bother counting symbols.
830 Call symbol_remove, instead of expanding it in place. Moved the
831 conditionalized `object_file_size' declaration down to
832 conditionalized block where it's used. When using the absolute
833 symbol for a fixup without a symbol, set sy_used_in_reloc.
834 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
835 the correct symbol for the absolute section.
837 * subsegs.c (section_symbol): Use symbol_new instead of
838 symbol_make, since we may want it to go into the symbol table.
839 Make the new symbol have internal linkage. If
840 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
841 symbol with the newly created GAS symbol.
842 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
843 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

848 (in_signed_range): New function.
850 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
851 (sparc_ip, label "immediate"): Reject constants for pcrel
852 instructions only if the relocation type indicates a "call"
853 instruction and the offset is within range of a "jmpl %g0". If
854 it's not in range, use the absolute section symbol plus an offset.
855 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
857 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
859 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
862 * configure.in: Eliminated all targets using obj-coff but not
863 defining BFD_ASSEMBLER; I think all such targets that are
864 supported will be matched by real CPU-OS combinations earlier in
866 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
867 some comments about the dpx2 configuration, but left it disabled,
868 since it couldn't be reached before.
869 (target a29k-amd-ebmonold): Deleted.
871 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
873 * config/tc-hppa.c (pa_import): Correctly handle importing of an
874 already defined symbol.

878 * config/tc-mips.c (mips_ip): Only accept overly large values for
879 the 'j' operand if there are no further alternatives for this
882 * config/obj-coffbfd.c (adjust_stab_section): Initialize
883 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
884 is not SEG_UNKNOWN rather than checking whether it is >= 0.
886 * config/tc-mips.c (mips_align): Take new argument, label, and use
887 it instead of global insn_label.
888 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
889 call to mips_emit_delay and pass it to mips_align.
891 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
893 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
895 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
896 argument to a .callinfo directive. Don't loop forever on errors.
898 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
899 use pre-defined registers as arguments.
901 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
903 * write.c (write_object_file): Check both S_IS_LOCAL and
904 S_IS_EXTERNAL when deciding whether to discard a symbol.
906 * config-gas.com: Scan Makefile.in, not version.c, for current
907 version number. Delete all versions of temp files when finished
908 with them. Create config.h.
910 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
911 values to reduce number of lookups with S_GET_VALUE. Skip debug
912 symbols to avoid "a really nasty bug". (From Holger Teutsch,
913 holger@botbso.rhein-main.de.)
914 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
915 field. (Also from Holger Teutsch.) Watch for a would-be register
916 mask that spans frags.
918 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
919 this_base, not line_base. (Patch from Andreas Arens,
920 ari@obelix.av.rwth-aachen.de.)
922 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
923 look local if they're exported or undefined. Used to be done for
926 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
927 Get it from the looked-up symbol, instead of using the string from
928 the input stream, which is no longer null-terminated.
929 (LEX_PCT): New macro, defaults to 0.
930 (lex_type): Use it for `%'.
932 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
933 (vip_op): Now static, and returns void. Callers changed. Added
935 (vip): Ditto. Call as_fatal directly if a program bug is
937 (op_hash): Let default initialization suffice.
939 * Makefile.in (literal.o): Provide dependencies.
941 * configure.in: Set new makefile variable OPCODES_LIB.

2641 empty string case like the HP assembler -- assume a value of
2644 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
2645 standard hpux include files to pick up various function decls.
2647 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

2659 so GAS can attach unwind descriptor information to a BFD symbol.
2660 * config/tc-hppa.c (fix_new_hppa): If necessary attach unwind
2661 descriptor information to the BFD symbol.
2662 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

2681 an example of marker relocations.
2682 * write.c (write_relocs): Instead of assuming size of a relocation
2683 is 4 bytes, pick up the size from relocation itself.

2713 pass new argument for i, j and o cases.
2714 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2935 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2936 the table, require that the one without bit 0x1000000 set come
2937 first. Require further that it be case 'b' or 'P'. The a29k
2938 opcode table already meets these constraints.
2939 (machine_ip): When handling case 'i' or 'A', make sure that the

2991 * write.c (write_relocs): For relocs that are pc_relative and
2992 pcrel_offset and not partial_inplace, adjust reloc->addend to

3049 default is to assume production environment, and reject configs
3050 still being worked on. Mark Elf configurations (except sparc and
3051 i386) as developmental. Deleted cases matching some generic names
3052 in favor of more specific names. (E.g., when we get Alpha

3069 through inclusion of tc-hppa.h. Delete all forward declarations
3070 for functions only used within tc-hppa.c, likewise for structures,
3071 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
3072 conditional code in a few small places.
3074 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3075 structures, global variables, forward declarations together.

3077 conditional code -- try to group conditional code together
3078 into a few places. Make all functions and variables which
3079 are only used within tc-hppa.c static. PARAMize all functions.
3080 Add comments to functions. Delete unused functions, variables,
3081 #defines, etc. Delete unused members within structures. Delete
3082 ldil;ble hacks -- it is believed they were installed to work
3083 around old gas bugs. Avoid using mixed case for local
3084 functions, variables, and structures. Fix formatting problems
3085 not found by GNU-indent. Add FIXME notices for things which
3086 should be worked on the near future. Delete lots of old
3087 useless (1.36 PA-SOM) code.

3116 a multiple of the section alignment rather than always a
3119 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
3120 bits are zero (eg they specify no relocations), then do not even
3121 bother adding their entries to thesymextn section.

3160 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3162 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3163 ELF, since the ELF object format does not have these type of
3164 relocations. Change the abort into as as_bad and return
3165 BFD_RELOC_NONE to silence compiler warnings.
3166 (md_assemble): Keep track of the instruction size. Allow white
3167 space between the $ and the constant for compatibility with older
3168 gases and other assemblers.
3169 (i386_operand): Skip spaces between $ and expression.

4200 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
4201 case to set obj_format=elf. Must go before i386-*-sysv* case that
4202 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
4203 *-*-solaris case, and move to before *-sysv* case that wants to
4204 set obj_format to coff.

4213 (obj_aout_frob_symbol): Set BSF_DEBUGGING for a constructor
4214 symbol, so that BFD doesn't tamper with the type.

4230 * Extensive changes to permit symbols to contain any expression
4231 type and to delay the computation of the expression until the
4232 value is actually needed. This permits setting symbols to values
4233 calculated based on object code size. Expressions were changed to
4234 no longer be in a section, to stop the overloading of segment and
4235 expression type that previously occurred.
4237 * as.c (big_section, pass1_section, diff_section, absent_section):
4239 (expr_section): Added (used for dummy symbols which hold

4323 (previous_section, previous_subsection): New vars.
4324 (obj_elf_section): Save current place in case DWARF code wants us
4325 to pop back to it. Handle unquoted section name as well as quoted
4326 section name. Don't crash on invalid strings.
4327 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
4330 * config/obj-elf.h: Don't include struc-symbol.h.

4415 (omagic): Removed unused variable.
4417 * Preliminary support for m88k-coff.

4439 sy_resolved and sy_resolving single bit fields.
4440 * symbols.c (symbol_new): Don't initialize sy_forward field.

5575 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5577 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5578 srcdir, might be in objdir.

5602 dropping a space immediately following an identifier.

5605 * config/tc-mips.c (macro): Use $AT if target register is zero in
5606 load instruction, which it can be for a floating point load.
5608 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5680 prototypes for all static functions. Moved existing minimal
5681 debugging format support info #ifndef OBJ_ECOFF blocks.

5732 * read.c (s_ignore): Don't declare is_end_of_line. It's
5733 redundant, and triggers a VMS gcc compiler bug.
5735 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5736 current segment as an argument. (Ignored in all cases but VMS.)
5737 All callers and definitions changed.

6054 (operand): Treat zero byte as end-of-operand.
6056 * configure.in (per-target): Look for with_bfd_assembler option.
6057 For now, only accept "no", until the merge is done.
6059 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
6060 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
6061 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
6062 * read.c: Finish conversion to S_* macros in the VMS only
6063 parts of the program. Add "const" modifier to hex_value.
6064 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
6066 * expr.c: Add "const" modifier to hex_value.
6067 * symbols.c: Finish conversion to S_* macros in the VMS only
6068 parts of the program. Add "const" modifier to
6069 md_[long,short]_jump_size. Remove declaration of const_flag
6070 (which will be declared in obj-vms.h).
6071 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6072 Fix arguments to VMS_write_object_file.
6073 * config-gas.com: New file. Script for VMS systems to set up the
6074 configuration to build gas for VMS, and create config.status.
6075 * make-gas.com: Redone to work with new scheme.
6076 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
6078 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

6082 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6083 types of malformed stabs. Change parsing algorithm so that we are

6086 resolve the data types of as many struct elements as possible
6087 when some part of the struct is not fully defined by the compiler.
6088 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
6090 * obj-vms.c (VMS_write_object_file): Define all vtable psects
6091 as symbols as well in the object file. Look for external functions
6092 that start with "__vt.", and turn them into variables, since the
6093 g++ compiler is incapable of doing this.
6094 * tc-vax.c: Add '1' option for backward compatibility with older GCC
6096 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
6097 * input-scrub.c (as_where): Fix bug where as would crash if we did not
6098 have the name of the source file yet.
6099 * config/ho-vms.h: define HO_VMS, not HO_VAX.
6101 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
6103 * read.c (s_data): Always use "data_section", since it'll map to
6104 SEG_DATA or SEG_E1 if needed.
6105 (s_lcomm): Likewise with bss_section.
6106 (s_fill): Use memset, not bzero.
6108 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

6120 * Changes for BFD_ASSEMBLER:
6121 * obj.h (obj_crawl_symbol_chain): Declare only if not
6123 (obj_header_append, obj_pre_write_hook): Ditto.
6124 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
6125 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

6130 (big_section, reg_section, pass1_section, diff_section,
6131 absent_section, text_section, data_section, bss_section): If
6132 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
6133 mapping to segT enum values.

6135 if these are used or defined, if BFD_ASSEMBLER.
6136 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old

6141 (had_errors, had_warnings): Provide prototypes for ANSI C even if
6143 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
6144 declare with format attribute for -Wformat checking.
6146 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
6148 * app.c, config/tc-*.c: Don't include read.h, since it is already
6151 * These are based on patches from Minh Tran-le
6152 <mtranle@paris.intellicorp.com>.
6153 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
6154 obj_format coffbfd and gas_target i386coff for target.
6155 (i[34]86-*-isc*): New host (uses sysv).
6156 * config/i386aix.mt: Removed (no longer used).
6157 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
6159 (LDFLAGS): Added, defined as -shlib.
6160 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
6161 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6162 (DOT_LABEL_PREFIX): Define.
6163 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
6164 name rather than L0\001.

6167 * symbols.c, symbols.h (local_bss_counter): Removed.
6168 * write.c (write_object_file): bss no longer uses

6176 (size_section): Restored sanity check.
6177 (do_relocs_for): Base section address on s_paddr rather than
6178 computing it. Adjust a29k R_IHIHALF special case to account for
6179 section paddr (used to require paddr to be zero). If there are no
6180 reclos, set s_relptr to 0. Set relocation size in object_headers.
6181 (fill_section): Always set s_vaddr here, removing
6182 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6183 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6184 Set STYP_INFO for .comment.

6189 (do_linenos_for): Set lineno size in object_headers.
6190 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6191 set s_vaddr here. If string_byte_count remains 4, set it back to
6192 0, and only write strings out if there are some. Call
6193 fill_section before do_relocs_for and do_linenos_for.
6194 (obj_coff_section): Handle optional quoted second argument giving
6195 section characteristics.
6196 (obj_coff_bss): Added to handle .bss.
6197 (obj_coff_ident): Added to handle .ident (puts string in .comment

6200 (fixup_mdeps): Change to segment. Call frag_wane after
6202 (fixup_segment): Explicitly check S_IS_COMMON before making 386
6203 adjustment (already happened only for common symbols, but this is
6205 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

6217 (do_scrub_next_char): For \", return " not '.
6218 (symbol_chars): Now const.
6220 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6221 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6223 * config/obj-coff.h: Don't use #elif.
6225 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6226 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

6253 using ZERO_BASED_SEGMENTS.
6254 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6255 never set segment address for SEG_E2 (.bss) and don't write out
6256 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6257 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6258 definitions, and don't merge tags with non-tags. Check for .bf
6259 rather than just checking whether the second character is b and
6260 the third character is f.
6261 (obj_coff_val): gcc can generate values which we don't handle
6262 correctly; discard information for now, since it only affects the
6263 debugging information.

6265 (yank_symbols): Don't merge labels.
6266 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6414 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6417 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6446 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6448 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6449 constant will not fit in an immediate field.
6450 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

6487 * Support for i386-sysv.
6488 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6526 * tc-z8k.c: lots of bug fixes
6528 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6530 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6531 #elif, since it is not supported by old compilers.
6532 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6533 couple of expressions in tc-m68k.c.
6535 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6537 * read.c (cons): If NO_RELOC is defined, use it.
6539 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6541 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6543 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6544 local labels to start with a .) and set REGISTER_PREFIX to %.
6545 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6547 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
6549 * messages.c: Comment changes.
6551 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

6561 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6563 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6564 sections starting from zero, rather than making them consecutive.
6565 This makes subsequent reloc calculations easier, esp if the object
6566 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6567 allocate lcomm in .data rather than in .bss. It seems that some
6568 tools can't cope with a non-zero sized bss before linkage.

6572 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6573 throughout. That enum no longer means what we thought it meant.

6594 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6596 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6597 .word is < -32768 or > 32767. The -J flag causes the error to be
6598 ignored. This is to catch over-sized switches generated by gcc on
6599 systems which don't support the broken .word hack.
6600 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6601 write.c (fixup_segment): check for signed .word overflow if
6602 WARN_SIGNED_OVERFLOW_WORD.

6631 From Steve Chamberlain:
6632 Makefile.in: Handle m68*-*-coff*.
6633 read.c, read.h: add mult argument to s_space
6635 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge

6680 * config/tc-m68k.c (init_table): Now const. Always include 68851
6681 data, so that "bc" is available to 68040 cache instructions.
6682 Added "tt0", "tt1", and 68ec030 variants.
6683 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6684 (enum _register): Added TT0, TT1.
6685 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass

6712 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6713 has already been formatted (but may still contain %-characters).
6716 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6718 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6719 written with indirection on the last two operands, which can be
6720 either data or address registers. Added a new operand type 'r'
6721 which accepts either register type. Added '(' to notend stuff in
6722 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

7069 local labels didn't work.
7070 * listing.c (list_symbol_table): don't core dump when there's no
7072 * write.c, write.h: call fix_new with the right number of args on
7074 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
7077 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7079 * app.c: MRI compatibility - allow single quote to start a string.
7080 * as.c: fix typo recently introduced.
7081 * as.h : Don't include aout/reloc.h - it's not right for COFF!
7082 * expr.c: Much rewriting, to accomodate MRI syntax for
7083 expressions. Also easier to read now.
7084 * listing.c: Put back defuns
7085 * read.c: modified to accept MRI syntax, put back listing pseudo
7086 ops so that an assembler built with NO_LISTING ignores list ops
7088 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7089 machine is a SPARC or a 29K.
7090 * config/obj-aout.c: added s_sect pseudo op
7091 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7092 fill in the timestamp.
7093 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7094 anymore, define all the relocs which the tc-<x> bit will use so we
7095 can translate from them to the coff types.
7096 * config/tc-a29k.c: reloc_type isn't ane enum any more
7097 * config/tc-m68k.c: Added NO_RELOC definition.
7099 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
7101 * Makefile.in: put header files before C source for TAGS; remove
7102 references to non-existent syscalls.h.
7104 * read.c, write.c subsegs.c: back out the .bss changes.
7106 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7108 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
7112 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7114 * symbols.c (local_label_name): symbols now start with ^A.
7116 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7117 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7118 generate these sections. .align: will use NOP_OPCODE or 0
7119 for padding. This is just for being nice to the
7122 * expr.c (operand): changed to generate local label "\001L0"
7123 starting with a ^A so that it is recognized as a local label.
7125 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7127 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7128 i/o opcodes - inb, inw, outb and outw. string manipulation with
7129 att syntax - scmp, slod, smov, ssca, ssto.
7131 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7132 to just after .file .
7134 In obj_crawl_symbol_chain() where it tries to put the external
7135 symbols apart, with the condition:
7136 (!S_IS_DEFINED(symbolP) &&
7137 !S_IS_DEBUG(symbolP) &&
7138 !SF_GET_STATICS(symbolP))
7139 it was moving too many symbols out. So I switch it back to the
7141 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7143 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7144 so that we don't use the F_RELFLG which make the linker complain
7145 that somebody has stripped the relocation info.
7147 Also, the AIX ld program require that the relocation table
7148 is sorted by r_vaddr like the standard ATT assembler does.
7150 [he also changed the sizeof(struct ...)'s into the coff
7151 style FOOSZ macros. I'm not sure this is right, but I can't
7152 remember why. xoxorich.]
7154 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
7156 * Makefile.in, configure.in, doc: use the doc. Build it, install
7159 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
7161 * read.c: white space and comments only.
7163 * configure.in: use the new atof-ns32.c for ns32k.
7165 * write.c: comment change only.
7167 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7168 aren't yet integrated.
7170 * tc-i860.[hc]: blew off the dust. Something must still be done
7171 about conflicting relocation types.
7173 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7176 * tc-i960.c, tc-sparc.c: white space and comments only.
7178 * tc-a29k.h: delete duplicate macro definition.
7180 * new file atof-ns32k.c copied from hack's last unreleased gas.
7182 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7184 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7187 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7188 ChangeLog's prior to this are sketchy at best. I have logs.
7189 They just aren't ChangeLogs.
7193 version-control: never
