754 section symbol, not C_LABEL.
756 * config/tc-mips.c (mips_ip): Permit a modifier in 'o' case, and

808 * read.c (emit_expr): Use memset to zero out memory, rather than
809 going through md_number_to_chars. This permits handling symbolic
810 arguments when the size is larger than sizeof (valueT), if

863 (control_regs): New pointer.
864 (m68k_ip): Use control_regs instead of testing CPU every time.

1444 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
1445 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
1446 and -many (all architectures).
1448 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

1457 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
1459 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
1460 branch with an instruction that uses $at, in case the branch is
1462 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
1463 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
1464 to make it pcrel_offset.
1465 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
1466 reloc->address; another gruesome hack to get gas reloc handling to
1469 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1471 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
1474 (emit_insn): New function.
1475 (md_assemble): Call it.
1476 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
1478 (lituse_pending): New variable. Set by anything that generates a
1479 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
1480 tested by code that might want to emit a LITUSE reloc.
1481 (emit_unaligned_io): New function. Currently calls md_assemble,
1482 but it should eventually be converted to generate the insn itself
1483 and call emit_insn directly.
1484 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
1485 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
1486 emit_bis_r): Likewise.

1488 (alpha_ip, label get_macro): Don't emit the final instruction if
1490 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
1491 unaligned memory access macros.
1492 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
1493 the value can't be resolved.
1495 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1497 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
1498 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
1499 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
1501 (mips_force_relocation): New function.
1502 (md_apply_fix): Set fixP->fx_done appropriately.
1503 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

1511 * config/tc-mips.c (enum mips_pic_level): New enum.
1512 (mips_pic): Change from int to enum mips_pic_level. Change all
1513 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
1514 (load_address): Handle EMBEDDED_PIC.
1515 (macro): Handle EMBEDDED_PIC in all PIC cases.
1516 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
1517 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
1518 -non_shared to use NO_PIC (this is how the Irix 5 assembler
1519 works). Do not permit -G with SVR4_PIC.
1520 (s_abicalls): Warn if -G was used, and force -G 0.
1521 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
1522 anything but a.out, not just for ELF. For ECOFF, don't generate a
1523 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
1525 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
1527 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1529 * config/tc-hppa.c (create_new_space): Use ints, not chars as
1530 parameters to avoid losing when compiling with HP CC.
1531 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
1533 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1535 * Makefile.in (config-stamp): If `defs' is defined, emit a
1536 preprocessor directive to create a macro named by this value into
1537 config.new; don't explicitly go for BFD_ASSEMBLER.
1538 * configure.in: Define `defs', not `BFDDEF'. Set it to
1539 MANY_SEGMENTS for any obj-coffbfd target.
1540 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
1541 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
1543 (LOCAL_LOADLIBES): Deleted.
1544 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
1545 * config/m88kcoff.mt (TDEFINES): Ditto.
1546 * config/ebmon29k.mt: Deleted.

1571 bfd_set_symtab is called.
1572 (dump_section_relocs): Note whether a symbol is a section symbol
1574 (adjust_reloc_syms): For now, always supply an absolute symbol for
1575 fixups without symbols but not yet `done'. Use section_symbol to
1576 get the symbol, instead of going directly for abs_symbol.
1577 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
1578 reloc is not a section symbol and is not in the symbol table.
1579 (set_symtab): New function, broken out from write_object_file.
1580 Counts symbol table instead of relying on an earlier count.
1581 (write_object_file): Call set_symtab, but do it after potentially
1582 invoking the *_frob_file macros. Don't bother counting symbols.
1583 Call symbol_remove, instead of expanding it in place. Moved the
1584 conditionalized `object_file_size' declaration down to
1585 conditionalized block where it's used. When using the absolute
1586 symbol for a fixup without a symbol, set sy_used_in_reloc.
1587 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
1588 the correct symbol for the absolute section.
1590 * subsegs.c (section_symbol): Use symbol_new instead of
1591 symbol_make, since we may want it to go into the symbol table.
1592 Make the new symbol have internal linkage. If
1593 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
1594 symbol with the newly created GAS symbol.
1595 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
1596 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

1601 (in_signed_range): New function.
1603 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
1604 (sparc_ip, label "immediate"): Reject constants for pcrel
1605 instructions only if the relocation type indicates a "call"
1606 instruction and the offset is within range of a "jmpl %g0". If
1607 it's not in range, use the absolute section symbol plus an offset.
1608 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
1610 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
1612 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
1615 * configure.in: Eliminated all targets using obj-coff but not
1616 defining BFD_ASSEMBLER; I think all such targets that are
1617 supported will be matched by real CPU-OS combinations earlier in
1619 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
1620 some comments about the dpx2 configuration, but left it disabled,
1621 since it couldn't be reached before.
1622 (target a29k-amd-ebmonold): Deleted.
1624 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

1632 the 'j' operand if there are no further alternatives for this
1635 * config/obj-coffbfd.c (adjust_stab_section): Initialize
1636 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
1637 is not SEG_UNKNOWN rather than checking whether it is >= 0.
1639 * config/tc-mips.c (mips_align): Take new argument, label, and use
1640 it instead of global insn_label.
1641 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
1642 call to mips_emit_delay and pass it to mips_align.
1644 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1646 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
1648 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
1649 argument to a .callinfo directive. Don't loop forever on errors.
1651 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
1652 use pre-defined registers as arguments.

1657 S_IS_EXTERNAL when deciding whether to discard a symbol.
1659 * config-gas.com: Scan Makefile.in, not version.c, for current
1660 version number. Delete all versions of temp files when finished
1661 with them. Create config.h.
1663 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
1664 values to reduce number of lookups with S_GET_VALUE. Skip debug
1665 symbols to avoid "a really nasty bug". (From Holger Teutsch,
1666 holger@botbso.rhein-main.de.)
1667 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
1668 field. (Also from Holger Teutsch.) Watch for a would-be register
1669 mask that spans frags.
1671 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
1672 this_base, not line_base. (Patch from Andreas Arens,
1673 ari@obelix.av.rwth-aachen.de.)
1675 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
1676 look local if they're exported or undefined. Used to be done for
1679 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
1680 Get it from the looked-up symbol, instead of using the string from
1681 the input stream, which is no longer null-terminated.
1682 (LEX_PCT): New macro, defaults to 0.
1683 (lex_type): Use it for `%'.
1685 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
1686 (vip_op): Now static, and returns void. Callers changed. Added
1688 (vip): Ditto. Call as_fatal directly if a program bug is

1735 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
1736 0xffff for 'j' to be compatible with MIPS assembler. These

3806 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
3808 * configure.in: Set bfd_gas for all sparc targets. Added facility
3809 for keeping or rejecting configurations still under development;
3810 default is to assume production environment, and reject configs
3811 still being worked on. Mark Elf configurations (except sparc and
3812 i386) as developmental. Deleted cases matching some generic names
3813 in favor of more specific names. (E.g., when we get Alpha

3830 through inclusion of tc-hppa.h. Delete all forward declarations
3831 for functions only used within tc-hppa.c, likewise for structures,
3832 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
3833 conditional code in a few small places.
3835 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3836 structures, global variables, forward declarations together.

3838 conditional code -- try to group conditional code together
3839 into a few places. Make all functions and variables which
3840 are only used within tc-hppa.c static. PARAMize all functions.
3841 Add comments to functions. Delete unused functions, variables,
3842 #defines, etc. Delete unused members within structures. Delete
3843 ldil;ble hacks -- it is believed they were installed to work
3844 around old gas bugs. Avoid using mixed case for local
3845 functions, variables, and structures. Fix formatting problems
3846 not found by GNU-indent. Add FIXME notices for things which
3847 should be worked on the near future. Delete lots of old
3848 useless (1.36 PA-SOM) code.

3862 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
3863 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
3865 * config/tc-hppa.c: Likewise.
3867 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
3868 of elf32_symbol_type.
3869 (pa_export_args): Likewise.
3870 (elf_hppa_final_processing): Likewise.
3871 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

3876 * config/tc-hppa.c: (md_section_align): Align all sections to
3877 a multiple of the section alignment rather than always a
3880 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
3881 bits are zero (eg they specify no relocations), then do not even
3882 bother adding their entries to thesymextn section.

3923 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
3924 call strchr for each character to see if it is a special char,
3925 instead add a second loop over special_chars. Set alignment
3926 of text, data and bss sections to 4.
3927 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3929 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3930 ELF, since the ELF object format does not have these type of
3931 relocations. Change the abort into as as_bad and return
3932 BFD_RELOC_NONE to silence compiler warnings.
3933 (md_assemble): Keep track of the instruction size. Allow white
3934 space between the $ and the constant for compatibility with older
3935 gases and other assemblers.

6319 a29k .bss section; the mondfe program doesn't like it.

6340 source directory, if that's not the current directory.
6342 * configure.in (per-host): Accept MIPS host with BSD version

6368 avoid some redefinition complaints on some systems.
6369 (const, volatile): Don't need these conditionally defined if we
6370 use CONST and VOLATILE from ansidecl.h.
6371 (seg_name): Use CONST, not const.

6375 * config/tc-mips.c: Reindented to GNU standards.
6377 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
6379 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
6380 (fixup_segment): Add a29k special case; the linker is not prepared
6381 to see a segment offset here.
6383 * app.c (do_scrub_next_char): Added new state, 10, modifying state

6386 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
6388 * Makefile.in: add dvi target; as-$(config).texinfo might live in
6389 srcdir, might be in objdir.
6391 * doc/Makefile.in: dvi depends on as.dvi

6419 dropping a space immediately following an identifier.
6420 * expr.c, write.c: Rewrote assert expressions to not use multiple
6421 lines; I don't think that can be done portably.
6422 * config/tc-mips.c (macro): Use $AT if target register is zero in
6423 load instruction, which it can be for a floating point load.

6436 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
6437 z8k-opc.h, not z8k.h.
6439 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
6442 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

6493 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.

6497 prototypes for all static functions. Moved existing minimal
6498 debugging format support info #ifndef OBJ_ECOFF blocks.

6547 * make-gas.com: Find obstack.obj if it's not in the current
6549 * read.c (s_ignore): Don't declare is_end_of_line. It's
6550 redundant, and triggers a VMS gcc compiler bug.
6552 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
6553 current segment as an argument. (Ignored in all cases but VMS.)
6554 All callers and definitions changed.
6556 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)

6881 * expr.c (operand): If character other than comma or newline is a
6882 logical end-of-line character, use the newline case.
6883 From Eric Youngdale:
6884 (operand): Set X_add_number field for floating-point numbers.
6885 (operand): Treat zero byte as end-of-operand.
6887 * configure.in (per-target): Look for with_bfd_assembler option.
6888 For now, only accept "no", until the merge is done.
6890 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
6891 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

6897 * expr.c: Add "const" modifier to hex_value.
6898 * symbols.c: Finish conversion to S_* macros in the VMS only
6899 parts of the program. Add "const" modifier to
6900 md_[long,short]_jump_size. Remove declaration of const_flag
6901 (which will be declared in obj-vms.h).
6902 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6903 Fix arguments to VMS_write_object_file.
6904 * config-gas.com: New file. Script for VMS systems to set up the
6905 configuration to build gas for VMS, and create config.status.
6906 * make-gas.com: Redone to work with new scheme.
6907 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
6909 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
6910 will swap bytes if needed on a big endian system. Use throughout
6912 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
6913 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6914 types of malformed stabs. Change parsing algorithm so that we are
6915 more certain of having all of the information that we need on hand.
6916 * obj-vms.c (final_forward_reference): New function, used to help
6917 resolve the data types of as many struct elements as possible

6935 SEG_DATA or SEG_E1 if needed.
6936 (s_lcomm): Likewise with bss_section.
6937 (s_fill): Use memset, not bzero.
6939 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

6961 (big_section, reg_section, pass1_section, diff_section,
6962 absent_section, text_section, data_section, bss_section): If
6963 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
6964 mapping to segT enum values.
6965 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
6966 if these are used or defined, if BFD_ASSEMBLER.
6967 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6968 subseg_new split into two functions.
6969 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6971 * as.h (volatile): Don't define if already defined.
6972 (had_errors, had_warnings): Provide prototypes for ANSI C even if
6974 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
6975 declare with format attribute for -Wformat checking.
6977 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
6979 * app.c, config/tc-*.c: Don't include read.h, since it is already
6982 * These are based on patches from Minh Tran-le
6983 <mtranle@paris.intellicorp.com>.
6984 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
6985 obj_format coffbfd and gas_target i386coff for target.

6987 * config/i386aix.mt: Removed (no longer used).
6988 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
6990 (LDFLAGS): Added, defined as -shlib.
6991 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
6992 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6993 (DOT_LABEL_PREFIX): Define.
6994 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
6995 name rather than L0\001.
6996 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
6998 * symbols.c, symbols.h (local_bss_counter): Removed.
6999 * write.c (write_object_file): bss no longer uses
7000 local_bss_counter. Pass correct data and bss size to
7001 VMS_write_object_file.
7002 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
7003 argument, rather than using local_bss_counter.

7007 (size_section): Restored sanity check.
7008 (do_relocs_for): Base section address on s_paddr rather than
7009 computing it. Adjust a29k R_IHIHALF special case to account for
7010 section paddr (used to require paddr to be zero). If there are no
7011 reclos, set s_relptr to 0. Set relocation size in object_headers.
7012 (fill_section): Always set s_vaddr here, removing
7013 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7014 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.

7019 H_{SET,GET}_* macros.
7020 (do_linenos_for): Set lineno size in object_headers.
7021 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7022 set s_vaddr here. If string_byte_count remains 4, set it back to
7023 0, and only write strings out if there are some. Call
7024 fill_section before do_relocs_for and do_linenos_for.
7025 (obj_coff_section): Handle optional quoted second argument giving
7026 section characteristics.

7054 * config/obj-coff.h: Don't use #elif.
7056 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't

7096 (yank_symbols): Don't merge labels.
7097 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7243 could be doing emulation.
7245 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7248 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

7318 * Support for i386-sysv.
7319 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

7357 * tc-z8k.c: lots of bug fixes
7359 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7361 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7362 #elif, since it is not supported by old compilers.
7363 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7364 couple of expressions in tc-m68k.c.
7366 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

7392 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
7394 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7395 sections starting from zero, rather than making them consecutive.
7396 This makes subsequent reloc calculations easier, esp if the object
7397 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7398 allocate lcomm in .data rather than in .bss. It seems that some
7399 tools can't cope with a non-zero sized bss before linkage.

7422 * Makefile.in (install): if $(tooldir) exists, install as in
7425 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
7427 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
7428 .word is < -32768 or > 32767. The -J flag causes the error to be
7429 ignored. This is to catch over-sized switches generated by gcc on
7430 systems which don't support the broken .word hack.
7431 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
7432 write.c (fixup_segment): check for signed .word overflow if
7433 WARN_SIGNED_OVERFLOW_WORD.
7435 * write.c (fixup_segment): fixed missing parens in expression
7436 checking for byte or word overflow.

7452 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
7454 * input-scrub.c (input_scrub_push): call input_file_begin, not
7456 messages.c (as_perror): print ": " between the passed in error and
7457 the strerror, like perror does.
7459 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
7461 * Makefile.in: use gas_target instead of modifying target_cpu.
7462 From Steve Chamberlain:
7463 Makefile.in: Handle m68*-*-coff*.
7464 read.c, read.h: add mult argument to s_space
7466 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
7467 Motorola and MIT syntax; gas can now assemble either type of
7469 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

7475 (write_object_file) call fixup_mdeps
7476 (fixup_segment) set fx_subsy to 0.
7477 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
7479 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
7482 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7484 * Makefile.in (LIBS): Include opcode library.
7486 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

7506 tc-i960.c (md_ri_to_chars): Always output bout object file in
7507 little endian byte order (used to use endianness of host).
7509 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7511 * config/tc-m68k.c (init_table): Now const. Always include 68851
7512 data, so that "bc" is available to 68040 cache instructions.
7513 Added "tt0", "tt1", and 68ec030 variants.
7514 (md_assemble): Complain if 68000 (only) and 68881 are specified.
7515 (enum _register): Added TT0, TT1.

7547 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
7549 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
7550 written with indirection on the last two operands, which can be
7551 either data or address registers. Added a new operand type 'r'
7552 which accepts either register type. Added '(' to notend stuff in
7553 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

7665 characteristics have been), default to 68020. Don't need extra
7666 quotes around error string.

7748 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
7750 * write.c (write_object_file): keep the fix_tail clean, which
7751 fixes a bug in -R where relocations were being lost.

7802 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
7804 * Makefile.in (install): Install into $(tooldir)/bin, since that's
7805 where gcc looks for it.
7807 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
7809 * Makefile.in: Changed some lines to be less confusing for some

7882 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
7884 * Makefile.in, configure.in: removed traces of namesubdir,

7888 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
7889 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
7890 copyrights to '92, changed some from Cygnus to FSF.
7892 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7894 * expr.c: If an expression is single comma, then return with
7895 SEG_ABSENT rather than an error - since the sparc front end does
7896 really strange things with things like fbge,a
7898 * as.h: include bfd.h if using many sections
7899 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
7900 local labels didn't work.
7901 * listing.c (list_symbol_table): don't core dump when there's no
7903 * write.c, write.h: call fix_new with the right number of args on
7905 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
7908 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7910 * app.c: MRI compatibility - allow single quote to start a string.
7911 * as.c: fix typo recently introduced.
7912 * as.h : Don't include aout/reloc.h - it's not right for COFF!
7913 * expr.c: Much rewriting, to accomodate MRI syntax for
7914 expressions. Also easier to read now.
7915 * listing.c: Put back defuns
7916 * read.c: modified to accept MRI syntax, put back listing pseudo
7917 ops so that an assembler built with NO_LISTING ignores list ops
7919 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7920 machine is a SPARC or a 29K.
7921 * config/obj-aout.c: added s_sect pseudo op
7922 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7923 fill in the timestamp.
7924 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7925 anymore, define all the relocs which the tc-<x> bit will use so we
7926 can translate from them to the coff types.
7927 * config/tc-a29k.c: reloc_type isn't ane enum any more
7928 * config/tc-m68k.c: Added NO_RELOC definition.
7930 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
7932 * Makefile.in: put header files before C source for TAGS; remove
7933 references to non-existent syscalls.h.
7935 * read.c, write.c subsegs.c: back out the .bss changes.
7937 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7939 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
7943 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7945 * symbols.c (local_label_name): symbols now start with ^A.
7947 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7948 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7949 generate these sections. .align: will use NOP_OPCODE or 0
7950 for padding. This is just for being nice to the
7953 * expr.c (operand): changed to generate local label "\001L0"
7954 starting with a ^A so that it is recognized as a local label.
7956 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7958 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7959 i/o opcodes - inb, inw, outb and outw. string manipulation with
7960 att syntax - scmp, slod, smov, ssca, ssto.
7962 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7963 to just after .file .
7965 In obj_crawl_symbol_chain() where it tries to put the external
7966 symbols apart, with the condition:
7967 (!S_IS_DEFINED(symbolP) &&
7968 !S_IS_DEBUG(symbolP) &&
7969 !SF_GET_STATICS(symbolP))
7970 it was moving too many symbols out. So I switch it back to the
7972 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7974 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7975 so that we don't use the F_RELFLG which make the linker complain
7976 that somebody has stripped the relocation info.
7978 Also, the AIX ld program require that the relocation table
7979 is sorted by r_vaddr like the standard ATT assembler does.
7981 [he also changed the sizeof(struct ...)'s into the coff
7982 style FOOSZ macros. I'm not sure this is right, but I can't
7983 remember why. xoxorich.]
7985 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
7987 * Makefile.in, configure.in, doc: use the doc. Build it, install

7992 * read.c: white space and comments only.
7994 * configure.in: use the new atof-ns32.c for ns32k.
7996 * write.c: comment change only.
7998 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7999 aren't yet integrated.
8001 * tc-i860.[hc]: blew off the dust. Something must still be done
8002 about conflicting relocation types.
8004 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8007 * tc-i960.c, tc-sparc.c: white space and comments only.
8009 * tc-a29k.h: delete duplicate macro definition.
8011 * new file atof-ns32k.c copied from hack's last unreleased gas.
8013 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
