7 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
8 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
9 message to try to ease confusion about autoconf's
10 "cross-compiling" message.

28 instructions. Keep track of the number of instructions seen since
29 an instruction which accesses the cache.

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

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

851 (control_regs): New pointer.
852 (m68k_ip): Use control_regs instead of testing CPU every time.

1444 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
1445 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
1447 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
1448 branch with an instruction that uses $at, in case the branch is
1450 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
1451 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
1452 to make it pcrel_offset.
1453 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
1454 reloc->address; another gruesome hack to get gas reloc handling to
1457 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1459 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
1462 (emit_insn): New function.
1463 (md_assemble): Call it.
1464 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
1466 (lituse_pending): New variable. Set by anything that generates a
1467 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
1468 tested by code that might want to emit a LITUSE reloc.
1469 (emit_unaligned_io): New function. Currently calls md_assemble,
1470 but it should eventually be converted to generate the insn itself
1471 and call emit_insn directly.
1472 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
1473 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
1474 emit_bis_r): Likewise.

1478 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
1479 unaligned memory access macros.
1480 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
1481 the value can't be resolved.
1483 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1485 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
1486 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
1487 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
1489 (mips_force_relocation): New function.
1490 (md_apply_fix): Set fixP->fx_done appropriately.
1491 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

1499 * config/tc-mips.c (enum mips_pic_level): New enum.
1500 (mips_pic): Change from int to enum mips_pic_level. Change all

1502 (load_address): Handle EMBEDDED_PIC.
1503 (macro): Handle EMBEDDED_PIC in all PIC cases.
1504 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
1505 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
1506 -non_shared to use NO_PIC (this is how the Irix 5 assembler
1507 works). Do not permit -G with SVR4_PIC.
1508 (s_abicalls): Warn if -G was used, and force -G 0.
1509 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
1510 anything but a.out, not just for ELF. For ECOFF, don't generate a
1511 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
1513 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
1515 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1517 * config/tc-hppa.c (create_new_space): Use ints, not chars as
1518 parameters to avoid losing when compiling with HP CC.
1519 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
1521 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1523 * Makefile.in (config-stamp): If `defs' is defined, emit a
1524 preprocessor directive to create a macro named by this value into
1525 config.new; don't explicitly go for BFD_ASSEMBLER.
1526 * configure.in: Define `defs', not `BFDDEF'. Set it to
1527 MANY_SEGMENTS for any obj-coffbfd target.
1528 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
1529 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
1531 (LOCAL_LOADLIBES): Deleted.
1532 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
1533 * config/m88kcoff.mt (TDEFINES): Ditto.

1559 bfd_set_symtab is called.
1560 (dump_section_relocs): Note whether a symbol is a section symbol
1562 (adjust_reloc_syms): For now, always supply an absolute symbol for
1563 fixups without symbols but not yet `done'. Use section_symbol to
1564 get the symbol, instead of going directly for abs_symbol.
1565 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
1566 reloc is not a section symbol and is not in the symbol table.
1567 (set_symtab): New function, broken out from write_object_file.
1568 Counts symbol table instead of relying on an earlier count.
1569 (write_object_file): Call set_symtab, but do it after potentially
1570 invoking the *_frob_file macros. Don't bother counting symbols.
1571 Call symbol_remove, instead of expanding it in place. Moved the
1572 conditionalized `object_file_size' declaration down to
1573 conditionalized block where it's used. When using the absolute
1574 symbol for a fixup without a symbol, set sy_used_in_reloc.
1575 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
1576 the correct symbol for the absolute section.
1578 * subsegs.c (section_symbol): Use symbol_new instead of
1579 symbol_make, since we may want it to go into the symbol table.
1580 Make the new symbol have internal linkage. If
1581 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
1582 symbol with the newly created GAS symbol.
1583 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
1584 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

1591 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
1592 (sparc_ip, label "immediate"): Reject constants for pcrel
1593 instructions only if the relocation type indicates a "call"
1594 instruction and the offset is within range of a "jmpl %g0". If
1595 it's not in range, use the absolute section symbol plus an offset.
1596 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
1598 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
1600 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
1603 * configure.in: Eliminated all targets using obj-coff but not
1604 defining BFD_ASSEMBLER; I think all such targets that are
1605 supported will be matched by real CPU-OS combinations earlier in
1607 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
1608 some comments about the dpx2 configuration, but left it disabled,
1609 since it couldn't be reached before.
1610 (target a29k-amd-ebmonold): Deleted.
1612 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

1620 the 'j' operand if there are no further alternatives for this
1623 * config/obj-coffbfd.c (adjust_stab_section): Initialize
1624 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
1625 is not SEG_UNKNOWN rather than checking whether it is >= 0.
1627 * config/tc-mips.c (mips_align): Take new argument, label, and use
1628 it instead of global insn_label.
1629 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
1630 call to mips_emit_delay and pass it to mips_align.
1632 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1634 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.

1645 S_IS_EXTERNAL when deciding whether to discard a symbol.
1647 * config-gas.com: Scan Makefile.in, not version.c, for current
1648 version number. Delete all versions of temp files when finished
1649 with them. Create config.h.
1651 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
1652 values to reduce number of lookups with S_GET_VALUE. Skip debug
1653 symbols to avoid "a really nasty bug". (From Holger Teutsch,
1654 holger@botbso.rhein-main.de.)
1655 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
1656 field. (Also from Holger Teutsch.) Watch for a would-be register
1657 mask that spans frags.
1659 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
1660 this_base, not line_base. (Patch from Andreas Arens,

1664 look local if they're exported or undefined. Used to be done for
1667 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
1668 Get it from the looked-up symbol, instead of using the string from
1669 the input stream, which is no longer null-terminated.
1670 (LEX_PCT): New macro, defaults to 0.
1671 (lex_type): Use it for `%'.
1673 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

1723 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
1724 0xffff for 'j' to be compatible with MIPS assembler. These

3792 OPTIONAL_REGISTER_PREFIX if either is already defined.
3794 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
3796 * configure.in: Set bfd_gas for all sparc targets. Added facility
3797 for keeping or rejecting configurations still under development;
3798 default is to assume production environment, and reject configs
3799 still being worked on. Mark Elf configurations (except sparc and
3800 i386) as developmental. Deleted cases matching some generic names
3801 in favor of more specific names. (E.g., when we get Alpha

3819 for functions only used within tc-hppa.c, likewise for structures,
3820 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
3821 conditional code in a few small places.
3823 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3824 structures, global variables, forward declarations together.

3827 into a few places. Make all functions and variables which
3828 are only used within tc-hppa.c static. PARAMize all functions.
3829 Add comments to functions. Delete unused functions, variables,
3830 #defines, etc. Delete unused members within structures. Delete
3831 ldil;ble hacks -- it is believed they were installed to work
3832 around old gas bugs. Avoid using mixed case for local
3833 functions, variables, and structures. Fix formatting problems
3834 not found by GNU-indent. Add FIXME notices for things which
3835 should be worked on the near future. Delete lots of old
3836 useless (1.36 PA-SOM) code.

3853 * config/tc-hppa.c: Likewise.
3855 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
3856 of elf32_symbol_type.
3857 (pa_export_args): Likewise.
3858 (elf_hppa_final_processing): Likewise.

3865 a multiple of the section alignment rather than always a
3868 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
3869 bits are zero (eg they specify no relocations), then do not even
3870 bother adding their entries to thesymextn section.

3915 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3917 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3918 ELF, since the ELF object format does not have these type of
3919 relocations. Change the abort into as as_bad and return
3920 BFD_RELOC_NONE to silence compiler warnings.
3921 (md_assemble): Keep track of the instruction size. Allow white

6307 a29k .bss section; the mondfe program doesn't like it.

6328 source directory, if that's not the current directory.
6330 * configure.in (per-host): Accept MIPS host with BSD version

6356 avoid some redefinition complaints on some systems.
6357 (const, volatile): Don't need these conditionally defined if we
6358 use CONST and VOLATILE from ansidecl.h.
6359 (seg_name): Use CONST, not const.
6361 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
6363 * config/tc-mips.c: Reindented to GNU standards.
6365 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
6367 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
6368 (fixup_segment): Add a29k special case; the linker is not prepared
6369 to see a segment offset here.
6371 * app.c (do_scrub_next_char): Added new state, 10, modifying state
6372 9 to only keep a space in between identifier characters.
6374 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
6376 * Makefile.in: add dvi target; as-$(config).texinfo might live in
6377 srcdir, might be in objdir.
6379 * doc/Makefile.in: dvi depends on as.dvi

6407 dropping a space immediately following an identifier.
6408 * expr.c, write.c: Rewrote assert expressions to not use multiple
6409 lines; I don't think that can be done portably.
6410 * config/tc-mips.c (macro): Use $AT if target register is zero in
6411 load instruction, which it can be for a floating point load.
6413 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

6424 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
6425 z8k-opc.h, not z8k.h.
6427 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
6430 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

6434 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)

6481 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.

6485 prototypes for all static functions. Moved existing minimal
6486 debugging format support info #ifndef OBJ_ECOFF blocks.

6535 * make-gas.com: Find obstack.obj if it's not in the current
6537 * read.c (s_ignore): Don't declare is_end_of_line. It's
6538 redundant, and triggers a VMS gcc compiler bug.
6540 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
6541 current segment as an argument. (Ignored in all cases but VMS.)
6542 All callers and definitions changed.

6558 (obj_elf_xstab): New routine.
6559 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
6560 argument to s_ignore. Put "#if 0" around unused code.

6682 for now; should be machine-dependent.
6684 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
6685 targets, forcing BFD use.

6852 * config/tc-sparc.c (architecture_requested, warn_on_bump,
6853 md_relax_table): Use default zero initialization.
6854 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
6855 latter, instead of selecting with preprocessor conditionals.
6857 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
6859 * configure.in: recognise all sparclite variants

6869 * expr.c (operand): If character other than comma or newline is a
6870 logical end-of-line character, use the newline case.
6871 From Eric Youngdale:
6872 (operand): Set X_add_number field for floating-point numbers.
6873 (operand): Treat zero byte as end-of-operand.
6875 * configure.in (per-target): Look for with_bfd_assembler option.
6876 For now, only accept "no", until the merge is done.
6878 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
6879 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

6885 * expr.c: Add "const" modifier to hex_value.
6886 * symbols.c: Finish conversion to S_* macros in the VMS only
6887 parts of the program. Add "const" modifier to
6888 md_[long,short]_jump_size. Remove declaration of const_flag
6889 (which will be declared in obj-vms.h).
6890 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6891 Fix arguments to VMS_write_object_file.
6892 * config-gas.com: New file. Script for VMS systems to set up the
6893 configuration to build gas for VMS, and create config.status.
6894 * make-gas.com: Redone to work with new scheme.
6895 * obj-vms.c: Patch to fix bug where we were not correctly parsing the

6900 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
6901 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6902 types of malformed stabs. Change parsing algorithm so that we are
6903 more certain of having all of the information that we need on hand.
6904 * obj-vms.c (final_forward_reference): New function, used to help
6905 resolve the data types of as many struct elements as possible

6909 * obj-vms.c (VMS_write_object_file): Define all vtable psects
6910 as symbols as well in the object file. Look for external functions

6913 * tc-vax.c: Add '1' option for backward compatibility with older GCC
6915 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

6923 SEG_DATA or SEG_E1 if needed.
6924 (s_lcomm): Likewise with bss_section.
6925 (s_fill): Use memset, not bzero.
6927 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

6949 (big_section, reg_section, pass1_section, diff_section,
6950 absent_section, text_section, data_section, bss_section): If
6951 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
6952 mapping to segT enum values.
6953 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
6954 if these are used or defined, if BFD_ASSEMBLER.
6955 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6956 subseg_new split into two functions.
6957 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6959 * as.h (volatile): Don't define if already defined.
6960 (had_errors, had_warnings): Provide prototypes for ANSI C even if
6962 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
6963 declare with format attribute for -Wformat checking.
6965 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
6967 * app.c, config/tc-*.c: Don't include read.h, since it is already
6970 * These are based on patches from Minh Tran-le
6971 <mtranle@paris.intellicorp.com>.
6972 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
6973 obj_format coffbfd and gas_target i386coff for target.

6975 * config/i386aix.mt: Removed (no longer used).
6976 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
6978 (LDFLAGS): Added, defined as -shlib.
6979 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
6980 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6981 (DOT_LABEL_PREFIX): Define.
6982 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
6983 name rather than L0\001.
6984 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
6986 * symbols.c, symbols.h (local_bss_counter): Removed.
6987 * write.c (write_object_file): bss no longer uses
6988 local_bss_counter. Pass correct data and bss size to
6989 VMS_write_object_file.

6995 (size_section): Restored sanity check.
6996 (do_relocs_for): Base section address on s_paddr rather than
6997 computing it. Adjust a29k R_IHIHALF special case to account for
6998 section paddr (used to require paddr to be zero). If there are no
6999 reclos, set s_relptr to 0. Set relocation size in object_headers.
7000 (fill_section): Always set s_vaddr here, removing
7001 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7002 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7003 Set STYP_INFO for .comment.
7004 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7005 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

7007 H_{SET,GET}_* macros.
7008 (do_linenos_for): Set lineno size in object_headers.
7009 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7010 set s_vaddr here. If string_byte_count remains 4, set it back to
7011 0, and only write strings out if there are some. Call
7012 fill_section before do_relocs_for and do_linenos_for.
7013 (obj_coff_section): Handle optional quoted second argument giving

7042 * config/obj-coff.h: Don't use #elif.
7044 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't

7231 could be doing emulation.
7233 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7236 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

7306 * Support for i386-sysv.
7307 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

7345 * tc-z8k.c: lots of bug fixes
7347 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7349 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7350 #elif, since it is not supported by old compilers.
7351 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7352 couple of expressions in tc-m68k.c.
7354 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

7380 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
7382 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7383 sections starting from zero, rather than making them consecutive.
7384 This makes subsequent reloc calculations easier, esp if the object
7385 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7386 allocate lcomm in .data rather than in .bss. It seems that some
7387 tools can't cope with a non-zero sized bss before linkage.

7395 "-mno-688[58]1" options.
7397 * tc-m68k.c: Added CPU32 support.

7410 * Makefile.in (install): if $(tooldir) exists, install as in
7413 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
7415 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
7416 .word is < -32768 or > 32767. The -J flag causes the error to be
7417 ignored. This is to catch over-sized switches generated by gcc on
7418 systems which don't support the broken .word hack.
7419 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
7420 write.c (fixup_segment): check for signed .word overflow if
7421 WARN_SIGNED_OVERFLOW_WORD.
7423 * write.c (fixup_segment): fixed missing parens in expression

7440 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
7442 * input-scrub.c (input_scrub_push): call input_file_begin, not
7444 messages.c (as_perror): print ": " between the passed in error and
7445 the strerror, like perror does.
7447 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

7464 (fixup_segment) set fx_subsy to 0.
7465 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
7467 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
7470 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7472 * Makefile.in (LIBS): Include opcode library.
7474 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

7495 little endian byte order (used to use endianness of host).
7497 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7499 * config/tc-m68k.c (init_table): Now const. Always include 68851
7500 data, so that "bc" is available to 68040 cache instructions.
7501 Added "tt0", "tt1", and 68ec030 variants.
7502 (md_assemble): Complain if 68000 (only) and 68881 are specified.
7503 (enum _register): Added TT0, TT1.
7504 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
7505 line number correctly in "internal error" messages. Don't print
7506 architecture-mismatch message for operand errors.
7508 From Colin Smith (colin@wrs.com):
7509 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
7510 than install_operand.

7535 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
7537 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
7538 written with indirection on the last two operands, which can be
7539 either data or address registers. Added a new operand type 'r'
7540 which accepts either register type. Added '(' to notend stuff in
7541 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

7653 characteristics have been), default to 68020. Don't need extra
7654 quotes around error string.

7787 * write.c (write_object_file): For b.out format, round up section
7788 start addresses to match required alignment.
7790 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
7792 * Makefile.in (install): Install into $(tooldir)/bin, since that's
7793 where gcc looks for it.
7795 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
7797 * Makefile.in: Changed some lines to be less confusing for some

7867 * expr.c (operand): if can't work out what sort of operand it is,
7868 then look through FLT_CHARS for a hint.
7870 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
7872 * Makefile.in, configure.in: removed traces of namesubdir,

7876 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
7877 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
7878 copyrights to '92, changed some from Cygnus to FSF.
7880 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7882 * expr.c: If an expression is single comma, then return with
7883 SEG_ABSENT rather than an error - since the sparc front end does
7884 really strange things with things like fbge,a
7886 * as.h: include bfd.h if using many sections
7887 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
7888 local labels didn't work.
7889 * listing.c (list_symbol_table): don't core dump when there's no
7891 * write.c, write.h: call fix_new with the right number of args on

7896 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7898 * app.c: MRI compatibility - allow single quote to start a string.
7899 * as.c: fix typo recently introduced.
7900 * as.h : Don't include aout/reloc.h - it's not right for COFF!
7901 * expr.c: Much rewriting, to accomodate MRI syntax for
7902 expressions. Also easier to read now.
7903 * listing.c: Put back defuns
7904 * read.c: modified to accept MRI syntax, put back listing pseudo
7905 ops so that an assembler built with NO_LISTING ignores list ops
7907 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7908 machine is a SPARC or a 29K.
7909 * config/obj-aout.c: added s_sect pseudo op
7910 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7911 fill in the timestamp.
7912 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7913 anymore, define all the relocs which the tc-<x> bit will use so we
7914 can translate from them to the coff types.
7915 * config/tc-a29k.c: reloc_type isn't ane enum any more
7916 * config/tc-m68k.c: Added NO_RELOC definition.
7918 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
7920 * Makefile.in: put header files before C source for TAGS; remove
7921 references to non-existent syscalls.h.
7923 * read.c, write.c subsegs.c: back out the .bss changes.
7925 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7927 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
7931 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7933 * symbols.c (local_label_name): symbols now start with ^A.
7935 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7936 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7937 generate these sections. .align: will use NOP_OPCODE or 0
7938 for padding. This is just for being nice to the
7941 * expr.c (operand): changed to generate local label "\001L0"
7942 starting with a ^A so that it is recognized as a local label.
7944 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7946 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7947 i/o opcodes - inb, inw, outb and outw. string manipulation with
7948 att syntax - scmp, slod, smov, ssca, ssto.
7950 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7951 to just after .file .
7953 In obj_crawl_symbol_chain() where it tries to put the external
7954 symbols apart, with the condition:
7955 (!S_IS_DEFINED(symbolP) &&
7956 !S_IS_DEBUG(symbolP) &&
7957 !SF_GET_STATICS(symbolP))
7958 it was moving too many symbols out. So I switch it back to the
7960 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7962 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7963 so that we don't use the F_RELFLG which make the linker complain
7964 that somebody has stripped the relocation info.
7966 Also, the AIX ld program require that the relocation table
7967 is sorted by r_vaddr like the standard ATT assembler does.
7969 [he also changed the sizeof(struct ...)'s into the coff
7970 style FOOSZ macros. I'm not sure this is right, but I can't
7971 remember why. xoxorich.]
7973 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

7982 * configure.in: use the new atof-ns32.c for ns32k.
7984 * write.c: comment change only.
7986 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7987 aren't yet integrated.
7989 * tc-i860.[hc]: blew off the dust. Something must still be done
7990 about conflicting relocation types.
7992 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7995 * tc-i960.c, tc-sparc.c: white space and comments only.
7997 * tc-a29k.h: delete duplicate macro definition.
7999 * new file atof-ns32k.c copied from hack's last unreleased gas.
8001 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8003 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8006 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8007 ChangeLog's prior to this are sketchy at best. I have logs.
8008 They just aren't ChangeLogs.
8015 version-control: never
