833 * read.c (emit_expr): Use memset to zero out memory, rather than
834 going through md_number_to_chars. This permits handling symbolic

888 (control_regs): New pointer.
889 (m68k_ip): Use control_regs instead of testing CPU every time.

961 VMS debugger now recognizes `long long' variables correctly.
962 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
963 for gcc2's predefined types "long double" (same as double, as

1447 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
1448 (md_begin): If an instruction has a size specific flag set, only
1449 add it if we are assembling that size.

1453 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
1454 cross section PC relative relocs right for COFF and ELF.
1456 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

1463 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
1464 the type of symbol set symbols which happen to be in the absolute
1465 or undefined section.

1469 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
1470 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
1471 and -many (all architectures).
1473 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

1482 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
1484 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
1485 branch with an instruction that uses $at, in case the branch is
1487 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
1488 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
1489 to make it pcrel_offset.
1490 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
1491 reloc->address; another gruesome hack to get gas reloc handling to
1494 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1496 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
1499 (emit_insn): New function.
1500 (md_assemble): Call it.
1501 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
1503 (lituse_pending): New variable. Set by anything that generates a
1504 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
1505 tested by code that might want to emit a LITUSE reloc.
1506 (emit_unaligned_io): New function. Currently calls md_assemble,
1507 but it should eventually be converted to generate the insn itself
1508 and call emit_insn directly.
1509 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
1510 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
1511 emit_bis_r): Likewise.

1520 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1522 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
1523 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
1524 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
1526 (mips_force_relocation): New function.
1527 (md_apply_fix): Set fixP->fx_done appropriately.
1528 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

1539 (load_address): Handle EMBEDDED_PIC.
1540 (macro): Handle EMBEDDED_PIC in all PIC cases.
1541 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
1542 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
1543 -non_shared to use NO_PIC (this is how the Irix 5 assembler
1544 works). Do not permit -G with SVR4_PIC.
1545 (s_abicalls): Warn if -G was used, and force -G 0.
1546 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
1547 anything but a.out, not just for ELF. For ECOFF, don't generate a
1548 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
1550 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
1552 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1554 * config/tc-hppa.c (create_new_space): Use ints, not chars as
1555 parameters to avoid losing when compiling with HP CC.
1556 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
1558 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1560 * Makefile.in (config-stamp): If `defs' is defined, emit a
1561 preprocessor directive to create a macro named by this value into
1562 config.new; don't explicitly go for BFD_ASSEMBLER.
1563 * configure.in: Define `defs', not `BFDDEF'. Set it to
1564 MANY_SEGMENTS for any obj-coffbfd target.
1565 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
1566 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
1568 (LOCAL_LOADLIBES): Deleted.
1569 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
1570 * config/m88kcoff.mt (TDEFINES): Ditto.

1574 * config/sparc.mt: Deleted.
1575 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

1596 bfd_set_symtab is called.
1597 (dump_section_relocs): Note whether a symbol is a section symbol
1599 (adjust_reloc_syms): For now, always supply an absolute symbol for
1600 fixups without symbols but not yet `done'. Use section_symbol to
1601 get the symbol, instead of going directly for abs_symbol.
1602 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
1603 reloc is not a section symbol and is not in the symbol table.
1604 (set_symtab): New function, broken out from write_object_file.
1605 Counts symbol table instead of relying on an earlier count.
1606 (write_object_file): Call set_symtab, but do it after potentially
1607 invoking the *_frob_file macros. Don't bother counting symbols.
1608 Call symbol_remove, instead of expanding it in place. Moved the
1609 conditionalized `object_file_size' declaration down to
1610 conditionalized block where it's used. When using the absolute
1611 symbol for a fixup without a symbol, set sy_used_in_reloc.
1612 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
1613 the correct symbol for the absolute section.
1615 * subsegs.c (section_symbol): Use symbol_new instead of
1616 symbol_make, since we may want it to go into the symbol table.
1617 Make the new symbol have internal linkage. If
1618 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
1619 symbol with the newly created GAS symbol.
1620 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
1621 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

1626 (in_signed_range): New function.
1628 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
1629 (sparc_ip, label "immediate"): Reject constants for pcrel
1630 instructions only if the relocation type indicates a "call"
1631 instruction and the offset is within range of a "jmpl %g0". If
1632 it's not in range, use the absolute section symbol plus an offset.
1633 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
1635 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
1637 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
1640 * configure.in: Eliminated all targets using obj-coff but not
1641 defining BFD_ASSEMBLER; I think all such targets that are
1642 supported will be matched by real CPU-OS combinations earlier in
1644 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
1645 some comments about the dpx2 configuration, but left it disabled,
1646 since it couldn't be reached before.
1647 (target a29k-amd-ebmonold): Deleted.
1649 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

1657 the 'j' operand if there are no further alternatives for this
1660 * config/obj-coffbfd.c (adjust_stab_section): Initialize
1661 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
1662 is not SEG_UNKNOWN rather than checking whether it is >= 0.
1664 * config/tc-mips.c (mips_align): Take new argument, label, and use
1665 it instead of global insn_label.
1666 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
1667 call to mips_emit_delay and pass it to mips_align.
1669 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1671 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
1673 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
1674 argument to a .callinfo directive. Don't loop forever on errors.
1676 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
1677 use pre-defined registers as arguments.

1681 * write.c (write_object_file): Check both S_IS_LOCAL and
1682 S_IS_EXTERNAL when deciding whether to discard a symbol.
1684 * config-gas.com: Scan Makefile.in, not version.c, for current
1685 version number. Delete all versions of temp files when finished
1686 with them. Create config.h.
1688 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
1689 values to reduce number of lookups with S_GET_VALUE. Skip debug
1690 symbols to avoid "a really nasty bug". (From Holger Teutsch,
1691 holger@botbso.rhein-main.de.)
1692 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
1693 field. (Also from Holger Teutsch.) Watch for a would-be register
1694 mask that spans frags.
1696 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
1697 this_base, not line_base. (Patch from Andreas Arens,
1698 ari@obelix.av.rwth-aachen.de.)
1700 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
1701 look local if they're exported or undefined. Used to be done for
1704 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
1705 Get it from the looked-up symbol, instead of using the string from
1706 the input stream, which is no longer null-terminated.
1707 (LEX_PCT): New macro, defaults to 0.
1708 (lex_type): Use it for `%'.
1710 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

1760 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
1761 0xffff for 'j' to be compatible with MIPS assembler. These

3834 for keeping or rejecting configurations still under development;
3835 default is to assume production environment, and reject configs
3836 still being worked on. Mark Elf configurations (except sparc and
3837 i386) as developmental. Deleted cases matching some generic names
3838 in favor of more specific names. (E.g., when we get Alpha

3866 Add comments to functions. Delete unused functions, variables,
3867 #defines, etc. Delete unused members within structures. Delete
3868 ldil;ble hacks -- it is believed they were installed to work
3869 around old gas bugs. Avoid using mixed case for local
3870 functions, variables, and structures. Fix formatting problems
3871 not found by GNU-indent. Add FIXME notices for things which
3872 should be worked on the near future. Delete lots of old
3873 useless (1.36 PA-SOM) code.

3892 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
3893 of elf32_symbol_type.
3894 (pa_export_args): Likewise.

3952 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3954 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3955 ELF, since the ELF object format does not have these type of
3956 relocations. Change the abort into as as_bad and return
3957 BFD_RELOC_NONE to silence compiler warnings.
3958 (md_assemble): Keep track of the instruction size. Allow white

6404 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

6444 dropping a space immediately following an identifier.

6446 lines; I don't think that can be done portably.
6447 * config/tc-mips.c (macro): Use $AT if target register is zero in

6571 Patches from Eric Youngdale:
6572 * make-gas.com: Find obstack.obj if it's not in the current
6574 * read.c (s_ignore): Don't declare is_end_of_line. It's
6575 redundant, and triggers a VMS gcc compiler bug.
6577 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
6578 current segment as an argument. (Ignored in all cases but VMS.)
6579 All callers and definitions changed.

6595 (obj_elf_xstab): New routine.
6596 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
6597 argument to s_ignore. Put "#if 0" around unused code.

6599 Call elf_xstabs for .stabs and .xstabs operators.
6601 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
6603 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
6606 * configure.in: mips-bsd configuration was missing format spec.
6609 * Makefile.in (Makefile): Depends on configure.in.
6611 * config/tc-mips.c (append_insn): Don't check for alignment of
6612 frag in memory; alignment of instructions in section is a separate

6632 * config/tc-sparc.c (s_xword): Now call big_cons, so large
6633 constants are accepted, but symbolic values are not. GCC will not
6634 generate the latter currently.
6636 * frags.c (frag_init): New function.
6637 (zero_address_frag, bss_address_frag): Now initialized at run
6639 * as.c (main): Call frag_init.

6715 new section/subsection.
6717 * read.c: Don't include ctype.h.

6913 For now, only accept "no", until the merge is done.
6915 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):

6922 * expr.c: Add "const" modifier to hex_value.
6923 * symbols.c: Finish conversion to S_* macros in the VMS only

6925 md_[long,short]_jump_size. Remove declaration of const_flag
6926 (which will be declared in obj-vms.h).
6927 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6928 Fix arguments to VMS_write_object_file.
6929 * config-gas.com: New file. Script for VMS systems to set up the

6989 mapping to segT enum values.
6990 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
6991 if these are used or defined, if BFD_ASSEMBLER.
6992 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6993 subseg_new split into two functions.
6994 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6996 * as.h (volatile): Don't define if already defined.
6997 (had_errors, had_warnings): Provide prototypes for ANSI C even if

7023 * symbols.c, symbols.h (local_bss_counter): Removed.
7024 * write.c (write_object_file): bss no longer uses
7025 local_bss_counter. Pass correct data and bss size to
7026 VMS_write_object_file.
7027 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
7028 argument, rather than using local_bss_counter.

7032 (size_section): Restored sanity check.
7033 (do_relocs_for): Base section address on s_paddr rather than
7034 computing it. Adjust a29k R_IHIHALF special case to account for
7035 section paddr (used to require paddr to be zero). If there are no
7036 reclos, set s_relptr to 0. Set relocation size in object_headers.
7037 (fill_section): Always set s_vaddr here, removing
7038 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7039 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7040 Set STYP_INFO for .comment.
7041 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7042 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

7044 H_{SET,GET}_* macros.
7045 (do_linenos_for): Set lineno size in object_headers.
7046 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7047 set s_vaddr here. If string_byte_count remains 4, set it back to
7048 0, and only write strings out if there are some. Call
7049 fill_section before do_relocs_for and do_linenos_for.
7050 (obj_coff_section): Handle optional quoted second argument giving
7051 section characteristics.
7052 (obj_coff_bss): Added to handle .bss.
7053 (obj_coff_ident): Added to handle .ident (puts string in .comment
7055 (obj_coff_lcomm): Put common symbols in .bss, not .data.
7056 (fixup_mdeps): Change to segment. Call frag_wane after
7058 (fixup_segment): Explicitly check S_IS_COMMON before making 386
7059 adjustment (already happened only for common symbols, but this is
7061 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
7062 * config/tc-i386.c (s_bss): Don't use if I386COFF.

7072 * app.c (app_push): Use memcpy, not bcopy.
7073 (do_scrub_next_char): For \", return " not '.
7074 (symbol_chars): Now const.
7076 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7077 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7079 * config/obj-coff.h: Don't use #elif.
7081 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7082 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
7084 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

7109 using ZERO_BASED_SEGMENTS.
7110 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7111 never set segment address for SEG_E2 (.bss) and don't write out
7112 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7113 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7114 definitions, and don't merge tags with non-tags. Check for .bf
7115 rather than just checking whether the second character is b and
7116 the third character is f.
7117 (obj_coff_val): gcc can generate values which we don't handle
7118 correctly; discard information for now, since it only affects the
7119 debugging information.
7120 (tag_find_or_name): Don't insert tags in the symbol table.
7121 (yank_symbols): Don't merge labels.
7122 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7125 (obj_coff_section): Accept and ignore a trailing quoted string, as
7126 used in AT&T i386 syntax.
7127 (fixup_segment): Take segment as argument. On the i386, adjust PC
7128 relative addends by the segment vaddr.

7267 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
7268 could be doing emulation.
7270 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7273 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

7302 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
7304 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
7305 constant will not fit in an immediate field.
7306 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

7341 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
7343 * Support for i386-sysv.
7344 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

7368 * tc-m68k.c (get_num): make it work for all segments, not just the
7371 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
7373 * configure.in: recognize i386-*-bsd emulation.

7382 * tc-z8k.c: lots of bug fixes
7384 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7386 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7387 #elif, since it is not supported by old compilers.
7388 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7389 couple of expressions in tc-m68k.c.
7391 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7393 * read.c (cons): If NO_RELOC is defined, use it.
7395 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
7397 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
7399 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
7400 local labels to start with a .) and set REGISTER_PREFIX to %.
7401 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
7403 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
7405 * messages.c: Comment changes.
7407 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

7410 * messages.c: If __STDC__ is not defined, define NO_STDARG.
7412 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
7414 * listing.c (debugging_pseudo): Add stabs and stabn as things to
7417 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
7419 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7420 sections starting from zero, rather than making them consecutive.
7421 This makes subsequent reloc calculations easier, esp if the object
7422 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7423 allocate lcomm in .data rather than in .bss. It seems that some
7424 tools can't cope with a non-zero sized bss before linkage.
7426 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7428 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
7429 throughout. That enum no longer means what we thought it meant.
7431 * tc-m68k.c (md_assemble, md_parse_option): Handle new
7432 "-mno-688[58]1" options.
7434 * tc-m68k.c: Added CPU32 support.

7445 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
7447 * Makefile.in (install): if $(tooldir) exists, install as in
7450 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
7452 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
7453 .word is < -32768 or > 32767. The -J flag causes the error to be
7454 ignored. This is to catch over-sized switches generated by gcc on
7455 systems which don't support the broken .word hack.
7456 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
7457 write.c (fixup_segment): check for signed .word overflow if
7458 WARN_SIGNED_OVERFLOW_WORD.
7460 * write.c (fixup_segment): fixed missing parens in expression
7461 checking for byte or word overflow.
7463 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

7475 * tc-i386.h : new coff defines
7477 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
7479 * input-scrub.c (input_scrub_push): call input_file_begin, not
7481 messages.c (as_perror): print ": " between the passed in error and
7482 the strerror, like perror does.
7484 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
7486 * Makefile.in: use gas_target instead of modifying target_cpu.
7487 From Steve Chamberlain:
7488 Makefile.in: Handle m68*-*-coff*.
7489 read.c, read.h: add mult argument to s_space
7491 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
7492 Motorola and MIT syntax; gas can now assemble either type of
7494 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
7495 From Steve Chamberlain:
7496 m68kcoff.mt: for m68k COFF.
7497 obj-coffbfd.c: (fixup_mdeps) added
7498 (size_section) removed bad sanity check
7499 (fill_section) added rs_machine_dependent case
7500 (write_object_file) call fixup_mdeps
7501 (fixup_segment) set fx_subsy to 0.
7502 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
7504 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala

7536 * config/tc-m68k.c (init_table): Now const. Always include 68851
7537 data, so that "bc" is available to 68040 cache instructions.
7538 Added "tt0", "tt1", and 68ec030 variants.
7539 (md_assemble): Complain if 68000 (only) and 68881 are specified.

7572 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
7574 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
7575 written with indirection on the last two operands, which can be
7576 either data or address registers. Added a new operand type 'r'
7577 which accepts either register type. Added '(' to notend stuff in
7578 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

7690 characteristics have been), default to 68020. Don't need extra
7691 quotes around error string.

7773 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
7775 * write.c (write_object_file): keep the fix_tail clean, which
7776 fixes a bug in -R where relocations were being lost.

7827 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
7829 * Makefile.in (install): Install into $(tooldir)/bin, since that's
7830 where gcc looks for it.

7914 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
7915 copyrights to '92, changed some from Cygnus to FSF.
7917 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7919 * expr.c: If an expression is single comma, then return with
7920 SEG_ABSENT rather than an error - since the sparc front end does
7921 really strange things with things like fbge,a
7923 * as.h: include bfd.h if using many sections
7924 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
7925 local labels didn't work.
7926 * listing.c (list_symbol_table): don't core dump when there's no
7928 * write.c, write.h: call fix_new with the right number of args on
7930 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
7933 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7935 * app.c: MRI compatibility - allow single quote to start a string.
7936 * as.c: fix typo recently introduced.
7937 * as.h : Don't include aout/reloc.h - it's not right for COFF!
7938 * expr.c: Much rewriting, to accomodate MRI syntax for
7939 expressions. Also easier to read now.
7940 * listing.c: Put back defuns
7941 * read.c: modified to accept MRI syntax, put back listing pseudo
7942 ops so that an assembler built with NO_LISTING ignores list ops
7944 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7945 machine is a SPARC or a 29K.
7946 * config/obj-aout.c: added s_sect pseudo op
7947 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7948 fill in the timestamp.
7949 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7950 anymore, define all the relocs which the tc-<x> bit will use so we
7951 can translate from them to the coff types.
7952 * config/tc-a29k.c: reloc_type isn't ane enum any more
7953 * config/tc-m68k.c: Added NO_RELOC definition.
7955 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
7957 * Makefile.in: put header files before C source for TAGS; remove
7958 references to non-existent syscalls.h.
7960 * read.c, write.c subsegs.c: back out the .bss changes.
7962 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7964 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
7968 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7970 * symbols.c (local_label_name): symbols now start with ^A.
7972 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7973 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7974 generate these sections. .align: will use NOP_OPCODE or 0
7975 for padding. This is just for being nice to the
7978 * expr.c (operand): changed to generate local label "\001L0"
7979 starting with a ^A so that it is recognized as a local label.
7981 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7983 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7984 i/o opcodes - inb, inw, outb and outw. string manipulation with
7985 att syntax - scmp, slod, smov, ssca, ssto.
7987 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7988 to just after .file .
7990 In obj_crawl_symbol_chain() where it tries to put the external
7991 symbols apart, with the condition:
7992 (!S_IS_DEFINED(symbolP) &&
7993 !S_IS_DEBUG(symbolP) &&
7994 !SF_GET_STATICS(symbolP))
7995 it was moving too many symbols out. So I switch it back to the
7997 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7999 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8000 so that we don't use the F_RELFLG which make the linker complain
8001 that somebody has stripped the relocation info.
8003 Also, the AIX ld program require that the relocation table
8004 is sorted by r_vaddr like the standard ATT assembler does.
8006 [he also changed the sizeof(struct ...)'s into the coff

8012 * Makefile.in, configure.in, doc: use the doc. Build it, install

8017 * read.c: white space and comments only.
8019 * configure.in: use the new atof-ns32.c for ns32k.
8021 * write.c: comment change only.
8023 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8024 aren't yet integrated.
8026 * tc-i860.[hc]: blew off the dust. Something must still be done
8027 about conflicting relocation types.
8029 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8032 * tc-i960.c, tc-sparc.c: white space and comments only.
8034 * tc-a29k.h: delete duplicate macro definition.
8036 * new file atof-ns32k.c copied from hack's last unreleased gas.

8045 They just aren't ChangeLogs.
