92 VMS debugger now recognizes `long long' variables correctly.
93 config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
94 for gcc2's predefined types "long double" (same as double, as
95 per gcc's current state), "long long int", "long long unsigned

98 "complex float", "complex double", and "complex long double" are
101 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead

461 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
463 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>

467 directory, and specify PSECT attributes explicitly to linker.
468 Also added missing label.
469 * Makefile.in (stamp-mk.com): Reference new variable
470 VMS_OTHER_OBJS for list of non-local object files, instead of

558 don't spew remainder of input file in error message.
559 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
560 message with reloc type and try to process remainder of file.
562 * doc/Makefile.in (install-info-as, install-info-gasp): New
563 targets, now explicitly checking $(srcdir) for info files.

572 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
573 flag rather than signedp field. Only permit extended range if
574 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
575 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
577 * config/tc-ppc.c (ppc_size): New static variable.
578 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.

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

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

631 (md_assemble): Call it.
632 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
634 (lituse_pending): New variable. Set by anything that generates a
635 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
636 tested by code that might want to emit a LITUSE reloc.
637 (emit_unaligned_io): New function. Currently calls md_assemble,
638 but it should eventually be converted to generate the insn itself
639 and call emit_insn directly.
640 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
641 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
642 emit_bis_r): Likewise.

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

670 (load_address): Handle EMBEDDED_PIC.
671 (macro): Handle EMBEDDED_PIC in all PIC cases.
672 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
673 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
674 -non_shared to use NO_PIC (this is how the Irix 5 assembler
675 works). Do not permit -G with SVR4_PIC.
676 (s_abicalls): Warn if -G was used, and force -G 0.
677 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
678 anything but a.out, not just for ELF. For ECOFF, don't generate a
679 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
681 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
683 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

689 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
691 * Makefile.in (config-stamp): If `defs' is defined, emit a
692 preprocessor directive to create a macro named by this value into
693 config.new; don't explicitly go for BFD_ASSEMBLER.
694 * configure.in: Define `defs', not `BFDDEF'. Set it to
695 MANY_SEGMENTS for any obj-coffbfd target.
696 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
697 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
699 (LOCAL_LOADLIBES): Deleted.
700 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
701 * config/m88kcoff.mt (TDEFINES): Ditto.

727 bfd_set_symtab is called.
728 (dump_section_relocs): Note whether a symbol is a section symbol
730 (adjust_reloc_syms): For now, always supply an absolute symbol for
731 fixups without symbols but not yet `done'. Use section_symbol to
732 get the symbol, instead of going directly for abs_symbol.
733 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
734 reloc is not a section symbol and is not in the symbol table.
735 (set_symtab): New function, broken out from write_object_file.
736 Counts symbol table instead of relying on an earlier count.
737 (write_object_file): Call set_symtab, but do it after potentially
738 invoking the *_frob_file macros. Don't bother counting symbols.
739 Call symbol_remove, instead of expanding it in place. Moved the
740 conditionalized `object_file_size' declaration down to
741 conditionalized block where it's used. When using the absolute
742 symbol for a fixup without a symbol, set sy_used_in_reloc.
743 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
744 the correct symbol for the absolute section.
746 * subsegs.c (section_symbol): Use symbol_new instead of
747 symbol_make, since we may want it to go into the symbol table.
748 Make the new symbol have internal linkage. If
749 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
750 symbol with the newly created GAS symbol.
751 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
752 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

757 (in_signed_range): New function.
759 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
760 (sparc_ip, label "immediate"): Reject constants for pcrel
761 instructions only if the relocation type indicates a "call"
762 instruction and the offset is within range of a "jmpl %g0". If
763 it's not in range, use the absolute section symbol plus an offset.
764 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
766 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
768 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
771 * configure.in: Eliminated all targets using obj-coff but not
772 defining BFD_ASSEMBLER; I think all such targets that are
773 supported will be matched by real CPU-OS combinations earlier in
775 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
776 some comments about the dpx2 configuration, but left it disabled,
777 since it couldn't be reached before.
778 (target a29k-amd-ebmonold): Deleted.
780 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

788 the 'j' operand if there are no further alternatives for this
791 * config/obj-coffbfd.c (adjust_stab_section): Initialize
792 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
793 is not SEG_UNKNOWN rather than checking whether it is >= 0.
795 * config/tc-mips.c (mips_align): Take new argument, label, and use
796 it instead of global insn_label.
797 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
798 call to mips_emit_delay and pass it to mips_align.
800 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
802 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
804 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
805 argument to a .callinfo directive. Don't loop forever on errors.
807 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
808 use pre-defined registers as arguments.
810 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
812 * write.c (write_object_file): Check both S_IS_LOCAL and
813 S_IS_EXTERNAL when deciding whether to discard a symbol.
815 * config-gas.com: Scan Makefile.in, not version.c, for current
816 version number. Delete all versions of temp files when finished
817 with them. Create config.h.
819 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
820 values to reduce number of lookups with S_GET_VALUE. Skip debug
821 symbols to avoid "a really nasty bug". (From Holger Teutsch,
822 holger@botbso.rhein-main.de.)
823 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
824 field. (Also from Holger Teutsch.) Watch for a would-be register
825 mask that spans frags.
827 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
828 this_base, not line_base. (Patch from Andreas Arens,
829 ari@obelix.av.rwth-aachen.de.)
831 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
832 look local if they're exported or undefined. Used to be done for
835 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
836 Get it from the looked-up symbol, instead of using the string from
837 the input stream, which is no longer null-terminated.
838 (LEX_PCT): New macro, defaults to 0.
839 (lex_type): Use it for `%'.
841 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
842 (vip_op): Now static, and returns void. Callers changed. Added
844 (vip): Ditto. Call as_fatal directly if a program bug is

848 * Makefile.in (literal.o): Provide dependencies.
850 * configure.in: Set new makefile variable OPCODES_LIB.

903 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
904 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

2844 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2845 the table, require that the one without bit 0x1000000 set come
2846 first. Require further that it be case 'b' or 'P'. The a29k

2957 for keeping or rejecting configurations still under development;
2958 default is to assume production environment, and reject configs
2959 still being worked on. Mark Elf configurations (except sparc and
2960 i386) as developmental. Deleted cases matching some generic names
2961 in favor of more specific names. (E.g., when we get Alpha

2980 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2981 conditional code in a few small places.
2983 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2984 structures, global variables, forward declarations together.

2987 into a few places. Make all functions and variables which
2988 are only used within tc-hppa.c static. PARAMize all functions.
2989 Add comments to functions. Delete unused functions, variables,
2990 #defines, etc. Delete unused members within structures. Delete
2991 ldil;ble hacks -- it is believed they were installed to work
2992 around old gas bugs. Avoid using mixed case for local
2993 functions, variables, and structures. Fix formatting problems
2994 not found by GNU-indent. Add FIXME notices for things which
2995 should be worked on the near future. Delete lots of old
2996 useless (1.36 PA-SOM) code.

3013 * config/tc-hppa.c: Likewise.
3015 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
3016 of elf32_symbol_type.
3017 (pa_export_args): Likewise.
3018 (elf_hppa_final_processing): Likewise.

3025 a multiple of the section alignment rather than always a
3028 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

3069 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3071 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3072 ELF, since the ELF object format does not have these type of
3073 relocations. Change the abort into as as_bad and return
3074 BFD_RELOC_NONE to silence compiler warnings.
3075 (md_assemble): Keep track of the instruction size. Allow white
3076 space between the $ and the constant for compatibility with older
3077 gases and other assemblers.
3078 (i386_operand): Skip spaces between $ and expression.

5639 * make-gas.com: Find obstack.obj if it's not in the current
5641 * read.c (s_ignore): Don't declare is_end_of_line. It's
5642 redundant, and triggers a VMS gcc compiler bug.
5644 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5645 current segment as an argument. (Ignored in all cases but VMS.)
5646 All callers and definitions changed.

5963 (operand): Treat zero byte as end-of-operand.
5965 * configure.in (per-target): Look for with_bfd_assembler option.
5966 For now, only accept "no", until the merge is done.
5968 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5969 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5978 md_[long,short]_jump_size. Remove declaration of const_flag
5979 (which will be declared in obj-vms.h).
5980 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5981 Fix arguments to VMS_write_object_file.
5982 * config-gas.com: New file. Script for VMS systems to set up the
5983 configuration to build gas for VMS, and create config.status.

6013 SEG_DATA or SEG_E1 if needed.
6014 (s_lcomm): Likewise with bss_section.
6015 (s_fill): Use memset, not bzero.
6017 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

6042 mapping to segT enum values.
6043 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
6044 if these are used or defined, if BFD_ASSEMBLER.
6045 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6046 subseg_new split into two functions.
6047 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6049 * as.h (volatile): Don't define if already defined.
6050 (had_errors, had_warnings): Provide prototypes for ANSI C even if

6085 (size_section): Restored sanity check.
6086 (do_relocs_for): Base section address on s_paddr rather than
6087 computing it. Adjust a29k R_IHIHALF special case to account for
6088 section paddr (used to require paddr to be zero). If there are no
6089 reclos, set s_relptr to 0. Set relocation size in object_headers.
6090 (fill_section): Always set s_vaddr here, removing
6091 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6092 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6093 Set STYP_INFO for .comment.
6094 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
6095 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
6096 (crawl_symbols): Handle 8 character section name correctly. Use
6097 H_{SET,GET}_* macros.
6098 (do_linenos_for): Set lineno size in object_headers.
6099 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6100 set s_vaddr here. If string_byte_count remains 4, set it back to
6101 0, and only write strings out if there are some. Call
6102 fill_section before do_relocs_for and do_linenos_for.
6103 (obj_coff_section): Handle optional quoted second argument giving
6104 section characteristics.
6105 (obj_coff_bss): Added to handle .bss.
6106 (obj_coff_ident): Added to handle .ident (puts string in .comment
6108 (obj_coff_lcomm): Put common symbols in .bss, not .data.
6109 (fixup_mdeps): Change to segment. Call frag_wane after
6111 (fixup_segment): Explicitly check S_IS_COMMON before making 386
6112 adjustment (already happened only for common symbols, but this is

6126 (do_scrub_next_char): For \", return " not '.
6127 (symbol_chars): Now const.
6129 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6130 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6132 * config/obj-coff.h: Don't use #elif.
6134 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6135 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

6165 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6166 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6167 definitions, and don't merge tags with non-tags. Check for .bf
6168 rather than just checking whether the second character is b and
6169 the third character is f.
6170 (obj_coff_val): gcc can generate values which we don't handle
6171 correctly; discard information for now, since it only affects the
6172 debugging information.
6173 (tag_find_or_name): Don't insert tags in the symbol table.
6174 (yank_symbols): Don't merge labels.
6175 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6321 could be doing emulation.
6323 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6326 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6396 * Support for i386-sysv.
6397 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6435 * tc-z8k.c: lots of bug fixes
6437 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6439 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6440 #elif, since it is not supported by old compilers.
6441 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6442 couple of expressions in tc-m68k.c.
6444 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6446 * read.c (cons): If NO_RELOC is defined, use it.

6452 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6453 local labels to start with a .) and set REGISTER_PREFIX to %.
6454 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6456 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

6470 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6472 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6473 sections starting from zero, rather than making them consecutive.
6474 This makes subsequent reloc calculations easier, esp if the object
6475 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6476 allocate lcomm in .data rather than in .bss. It seems that some
6477 tools can't cope with a non-zero sized bss before linkage.
6479 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6481 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6482 throughout. That enum no longer means what we thought it meant.

6485 "-mno-688[58]1" options.
6487 * tc-m68k.c: Added CPU32 support.

6498 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6500 * Makefile.in (install): if $(tooldir) exists, install as in
6503 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6505 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6506 .word is < -32768 or > 32767. The -J flag causes the error to be
6507 ignored. This is to catch over-sized switches generated by gcc on
6508 systems which don't support the broken .word hack.
6509 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6510 write.c (fixup_segment): check for signed .word overflow if
6511 WARN_SIGNED_OVERFLOW_WORD.
6513 * write.c (fixup_segment): fixed missing parens in expression
6514 checking for byte or word overflow.

6528 * tc-i386.h : new coff defines
6530 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6532 * input-scrub.c (input_scrub_push): call input_file_begin, not
6534 messages.c (as_perror): print ": " between the passed in error and
6535 the strerror, like perror does.
6537 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6539 * Makefile.in: use gas_target instead of modifying target_cpu.
6540 From Steve Chamberlain:
6541 Makefile.in: Handle m68*-*-coff*.
6542 read.c, read.h: add mult argument to s_space
6544 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6545 Motorola and MIT syntax; gas can now assemble either type of
6547 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6549 m68kcoff.mt: for m68k COFF.
6550 obj-coffbfd.c: (fixup_mdeps) added
6551 (size_section) removed bad sanity check
6552 (fill_section) added rs_machine_dependent case
6553 (write_object_file) call fixup_mdeps
6554 (fixup_segment) set fx_subsy to 0.
6555 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6557 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6560 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6562 * Makefile.in (LIBS): Include opcode library.
6564 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6589 * config/tc-m68k.c (init_table): Now const. Always include 68851
6590 data, so that "bc" is available to 68040 cache instructions.
6591 Added "tt0", "tt1", and 68ec030 variants.
6592 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6593 (enum _register): Added TT0, TT1.

6625 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6627 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6628 written with indirection on the last two operands, which can be
6629 either data or address registers. Added a new operand type 'r'
6630 which accepts either register type. Added '(' to notend stuff in
6631 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6743 characteristics have been), default to 68020. Don't need extra
6744 quotes around error string.

6877 * write.c (write_object_file): For b.out format, round up section
6878 start addresses to match required alignment.
6880 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6882 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6883 where gcc looks for it.
6885 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6887 * Makefile.in: Changed some lines to be less confusing for some

6962 * Makefile.in, configure.in: removed traces of namesubdir,

6966 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6967 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6968 copyrights to '92, changed some from Cygnus to FSF.
6970 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6972 * expr.c: If an expression is single comma, then return with
6973 SEG_ABSENT rather than an error - since the sparc front end does
6974 really strange things with things like fbge,a
6976 * as.h: include bfd.h if using many sections
6977 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6978 local labels didn't work.
6979 * listing.c (list_symbol_table): don't core dump when there's no
6981 * write.c, write.h: call fix_new with the right number of args on

6986 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6988 * app.c: MRI compatibility - allow single quote to start a string.
6989 * as.c: fix typo recently introduced.
6990 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6991 * expr.c: Much rewriting, to accomodate MRI syntax for
6992 expressions. Also easier to read now.
6993 * listing.c: Put back defuns
6994 * read.c: modified to accept MRI syntax, put back listing pseudo
6995 ops so that an assembler built with NO_LISTING ignores list ops
6997 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6998 machine is a SPARC or a 29K.
6999 * config/obj-aout.c: added s_sect pseudo op
7000 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7001 fill in the timestamp.
7002 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7003 anymore, define all the relocs which the tc-<x> bit will use so we
7004 can translate from them to the coff types.
7005 * config/tc-a29k.c: reloc_type isn't ane enum any more
7006 * config/tc-m68k.c: Added NO_RELOC definition.
7008 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
7010 * Makefile.in: put header files before C source for TAGS; remove
7011 references to non-existent syscalls.h.
7013 * read.c, write.c subsegs.c: back out the .bss changes.
7015 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7017 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
7021 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7023 * symbols.c (local_label_name): symbols now start with ^A.
7025 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7026 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7027 generate these sections. .align: will use NOP_OPCODE or 0
7028 for padding. This is just for being nice to the
7031 * expr.c (operand): changed to generate local label "\001L0"
7032 starting with a ^A so that it is recognized as a local label.
7034 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7036 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7037 i/o opcodes - inb, inw, outb and outw. string manipulation with
7038 att syntax - scmp, slod, smov, ssca, ssto.
7040 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7041 to just after .file .
7043 In obj_crawl_symbol_chain() where it tries to put the external
7044 symbols apart, with the condition:
7045 (!S_IS_DEFINED(symbolP) &&
7046 !S_IS_DEBUG(symbolP) &&
7047 !SF_GET_STATICS(symbolP))
7048 it was moving too many symbols out. So I switch it back to the
7050 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7052 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7053 so that we don't use the F_RELFLG which make the linker complain
7054 that somebody has stripped the relocation info.
7056 Also, the AIX ld program require that the relocation table
7057 is sorted by r_vaddr like the standard ATT assembler does.
7059 [he also changed the sizeof(struct ...)'s into the coff
7060 style FOOSZ macros. I'm not sure this is right, but I can't
7061 remember why. xoxorich.]
7063 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
7065 * Makefile.in, configure.in, doc: use the doc. Build it, install

7072 * configure.in: use the new atof-ns32.c for ns32k.
7074 * write.c: comment change only.
7076 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7077 aren't yet integrated.
7079 * tc-i860.[hc]: blew off the dust. Something must still be done
7080 about conflicting relocation types.
7082 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
