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

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

831 (control_regs): New pointer.
832 (m68k_ip): Use control_regs instead of testing CPU every time.

1447 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
1448 tested by code that might want to emit a LITUSE reloc.
1449 (emit_unaligned_io): New function. Currently calls md_assemble,
1450 but it should eventually be converted to generate the insn itself
1451 and call emit_insn directly.
1452 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
1453 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

1465 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
1466 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
1467 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

1482 (load_address): Handle EMBEDDED_PIC.
1483 (macro): Handle EMBEDDED_PIC in all PIC cases.
1484 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
1485 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
1486 -non_shared to use NO_PIC (this is how the Irix 5 assembler
1487 works). Do not permit -G with SVR4_PIC.
1488 (s_abicalls): Warn if -G was used, and force -G 0.
1489 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
1490 anything but a.out, not just for ELF. For ECOFF, don't generate a

1493 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
1495 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1497 * config/tc-hppa.c (create_new_space): Use ints, not chars as
1498 parameters to avoid losing when compiling with HP CC.
1499 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
1501 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1503 * Makefile.in (config-stamp): If `defs' is defined, emit a
1504 preprocessor directive to create a macro named by this value into
1505 config.new; don't explicitly go for BFD_ASSEMBLER.
1506 * configure.in: Define `defs', not `BFDDEF'. Set it to
1507 MANY_SEGMENTS for any obj-coffbfd target.
1508 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
1509 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
1511 (LOCAL_LOADLIBES): Deleted.
1512 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
1513 * config/m88kcoff.mt (TDEFINES): Ditto.

1539 bfd_set_symtab is called.
1540 (dump_section_relocs): Note whether a symbol is a section symbol
1542 (adjust_reloc_syms): For now, always supply an absolute symbol for
1543 fixups without symbols but not yet `done'. Use section_symbol to
1544 get the symbol, instead of going directly for abs_symbol.
1545 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
1546 reloc is not a section symbol and is not in the symbol table.
1547 (set_symtab): New function, broken out from write_object_file.
1548 Counts symbol table instead of relying on an earlier count.
1549 (write_object_file): Call set_symtab, but do it after potentially
1550 invoking the *_frob_file macros. Don't bother counting symbols.
1551 Call symbol_remove, instead of expanding it in place. Moved the
1552 conditionalized `object_file_size' declaration down to
1553 conditionalized block where it's used. When using the absolute
1554 symbol for a fixup without a symbol, set sy_used_in_reloc.
1555 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
1556 the correct symbol for the absolute section.
1558 * subsegs.c (section_symbol): Use symbol_new instead of
1559 symbol_make, since we may want it to go into the symbol table.
1560 Make the new symbol have internal linkage. If
1561 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
1562 symbol with the newly created GAS symbol.
1563 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
1564 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

1571 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
1572 (sparc_ip, label "immediate"): Reject constants for pcrel
1573 instructions only if the relocation type indicates a "call"
1574 instruction and the offset is within range of a "jmpl %g0". If
1575 it's not in range, use the absolute section symbol plus an offset.
1576 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
1578 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
1580 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
1583 * configure.in: Eliminated all targets using obj-coff but not
1584 defining BFD_ASSEMBLER; I think all such targets that are
1585 supported will be matched by real CPU-OS combinations earlier in
1587 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
1588 some comments about the dpx2 configuration, but left it disabled,
1589 since it couldn't be reached before.
1590 (target a29k-amd-ebmonold): Deleted.

1600 the 'j' operand if there are no further alternatives for this
1603 * config/obj-coffbfd.c (adjust_stab_section): Initialize
1604 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
1605 is not SEG_UNKNOWN rather than checking whether it is >= 0.
1607 * config/tc-mips.c (mips_align): Take new argument, label, and use
1608 it instead of global insn_label.
1609 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
1610 call to mips_emit_delay and pass it to mips_align.
1612 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1614 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.

1625 S_IS_EXTERNAL when deciding whether to discard a symbol.
1627 * config-gas.com: Scan Makefile.in, not version.c, for current
1628 version number. Delete all versions of temp files when finished
1629 with them. Create config.h.

1632 values to reduce number of lookups with S_GET_VALUE. Skip debug
1633 symbols to avoid "a really nasty bug". (From Holger Teutsch,
1634 holger@botbso.rhein-main.de.)
1635 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
1636 field. (Also from Holger Teutsch.) Watch for a would-be register
1637 mask that spans frags.
1639 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
1640 this_base, not line_base. (Patch from Andreas Arens,

1644 look local if they're exported or undefined. Used to be done for
1647 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
1648 Get it from the looked-up symbol, instead of using the string from
1649 the input stream, which is no longer null-terminated.

1651 (lex_type): Use it for `%'.
1653 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

3771 * config/tc-m68k.h: Don't define REGISTER_PREFIX or
3772 OPTIONAL_REGISTER_PREFIX if either is already defined.
3774 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
3776 * configure.in: Set bfd_gas for all sparc targets. Added facility
3777 for keeping or rejecting configurations still under development;
3778 default is to assume production environment, and reject configs
3779 still being worked on. Mark Elf configurations (except sparc and
3780 i386) as developmental. Deleted cases matching some generic names
3781 in favor of more specific names. (E.g., when we get Alpha
3782 support, we'll still only support VMS for Vax.)
3784 * config/tc-sparc.h (md_end): New macro.
3785 * config/tc-sparc.c (md_end): Function deleted.
3786 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

3796 against placing additional object-file dependent code here. Warn
3797 against contaminating all of GAS with the internals of tc-hppa.c
3798 through inclusion of tc-hppa.h. Delete all forward declarations
3799 for functions only used within tc-hppa.c, likewise for structures,
3800 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
3801 conditional code in a few small places.
3803 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3804 structures, global variables, forward declarations together.
3805 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
3806 conditional code -- try to group conditional code together
3807 into a few places. Make all functions and variables which
3808 are only used within tc-hppa.c static. PARAMize all functions.
3809 Add comments to functions. Delete unused functions, variables,
3810 #defines, etc. Delete unused members within structures. Delete
3811 ldil;ble hacks -- it is believed they were installed to work
3812 around old gas bugs. Avoid using mixed case for local
3813 functions, variables, and structures. Fix formatting problems
3814 not found by GNU-indent. Add FIXME notices for things which
3815 should be worked on the near future. Delete lots of old
3816 useless (1.36 PA-SOM) code.
3818 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
3819 field of the fixS structure. Needed to build unwind

3833 * config/tc-hppa.c: Likewise.
3835 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
3836 of elf32_symbol_type.
3837 (pa_export_args): Likewise.
3838 (elf_hppa_final_processing): Likewise.
3839 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

3844 * config/tc-hppa.c: (md_section_align): Align all sections to
3845 a multiple of the section alignment rather than always a
3848 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
3849 bits are zero (eg they specify no relocations), then do not even
3850 bother adding their entries to thesymextn section.

3893 instead add a second loop over special_chars. Set alignment
3894 of text, data and bss sections to 4.
3895 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3897 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3898 ELF, since the ELF object format does not have these type of
3899 relocations. Change the abort into as as_bad and return
3900 BFD_RELOC_NONE to silence compiler warnings.
3901 (md_assemble): Keep track of the instruction size. Allow white
3902 space between the $ and the constant for compatibility with older

6287 a29k .bss section; the mondfe program doesn't like it.

6308 source directory, if that's not the current directory.
6310 * configure.in (per-host): Accept MIPS host with BSD version

6336 avoid some redefinition complaints on some systems.
6337 (const, volatile): Don't need these conditionally defined if we
6338 use CONST and VOLATILE from ansidecl.h.
6339 (seg_name): Use CONST, not const.
6341 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
6343 * config/tc-mips.c: Reindented to GNU standards.
6345 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
6347 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
6348 (fixup_segment): Add a29k special case; the linker is not prepared
6349 to see a segment offset here.
6351 * app.c (do_scrub_next_char): Added new state, 10, modifying state
6352 9 to only keep a space in between identifier characters.
6354 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
6356 * Makefile.in: add dvi target; as-$(config).texinfo might live in
6357 srcdir, might be in objdir.
6359 * doc/Makefile.in: dvi depends on as.dvi

6387 dropping a space immediately following an identifier.
6388 * expr.c, write.c: Rewrote assert expressions to not use multiple
6389 lines; I don't think that can be done portably.
6390 * config/tc-mips.c (macro): Use $AT if target register is zero in
6391 load instruction, which it can be for a floating point load.

6404 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
6405 z8k-opc.h, not z8k.h.
6407 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
6410 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

6465 prototypes for all static functions. Moved existing minimal
6466 debugging format support info #ifndef OBJ_ECOFF blocks.

6515 * make-gas.com: Find obstack.obj if it's not in the current
6517 * read.c (s_ignore): Don't declare is_end_of_line. It's
6518 redundant, and triggers a VMS gcc compiler bug.
6520 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
6521 current segment as an argument. (Ignored in all cases but VMS.)
6522 All callers and definitions changed.

6540 argument to s_ignore. Put "#if 0" around unused code.
6541 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
6542 Call elf_xstabs for .stabs and .xstabs operators.
6544 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
6546 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
6549 * configure.in: mips-bsd configuration was missing format spec.
6552 * Makefile.in (Makefile): Depends on configure.in.
6554 * config/tc-mips.c (append_insn): Don't check for alignment of
6555 frag in memory; alignment of instructions in section is a separate

6564 Tue Mar 2 00:50:43 1993 John Gilmore (gnu@cygnus.com)

6849 * expr.c (operand): If character other than comma or newline is a
6850 logical end-of-line character, use the newline case.

6853 (operand): Treat zero byte as end-of-operand.
6855 * configure.in (per-target): Look for with_bfd_assembler option.
6856 For now, only accept "no", until the merge is done.

6868 md_[long,short]_jump_size. Remove declaration of const_flag
6869 (which will be declared in obj-vms.h).
6870 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6871 Fix arguments to VMS_write_object_file.
6872 * config-gas.com: New file. Script for VMS systems to set up the

6881 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6882 types of malformed stabs. Change parsing algorithm so that we are
6883 more certain of having all of the information that we need on hand.
6884 * obj-vms.c (final_forward_reference): New function, used to help

6903 SEG_DATA or SEG_E1 if needed.
6904 (s_lcomm): Likewise with bss_section.
6905 (s_fill): Use memset, not bzero.

6934 if these are used or defined, if BFD_ASSEMBLER.
6935 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6936 subseg_new split into two functions.
6937 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6939 * as.h (volatile): Don't define if already defined.
6940 (had_errors, had_warnings): Provide prototypes for ANSI C even if

6943 declare with format attribute for -Wformat checking.
6945 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
6947 * app.c, config/tc-*.c: Don't include read.h, since it is already

6960 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6961 (DOT_LABEL_PREFIX): Define.

6963 name rather than L0\001.
6964 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
6966 * symbols.c, symbols.h (local_bss_counter): Removed.
6967 * write.c (write_object_file): bss no longer uses

6975 (size_section): Restored sanity check.
6976 (do_relocs_for): Base section address on s_paddr rather than
6977 computing it. Adjust a29k R_IHIHALF special case to account for

6979 reclos, set s_relptr to 0. Set relocation size in object_headers.
6980 (fill_section): Always set s_vaddr here, removing
6981 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set

6987 H_{SET,GET}_* macros.
6988 (do_linenos_for): Set lineno size in object_headers.
6989 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6990 set s_vaddr here. If string_byte_count remains 4, set it back to
6991 0, and only write strings out if there are some. Call
6992 fill_section before do_relocs_for and do_linenos_for.
6993 (obj_coff_section): Handle optional quoted second argument giving
6994 section characteristics.
6995 (obj_coff_bss): Added to handle .bss.

7016 (do_scrub_next_char): For \", return " not '.
7017 (symbol_chars): Now const.
7019 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7020 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7022 * config/obj-coff.h: Don't use #elif.
7024 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7025 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

7055 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7056 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7057 definitions, and don't merge tags with non-tags. Check for .bf
7058 rather than just checking whether the second character is b and
7059 the third character is f.
7060 (obj_coff_val): gcc can generate values which we don't handle

7064 (yank_symbols): Don't merge labels.
7065 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7210 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
7211 could be doing emulation.
7213 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7216 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
7219 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)

7245 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
7247 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
7248 constant will not fit in an immediate field.
7249 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

7284 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
7286 * Support for i386-sysv.
7287 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

7325 * tc-z8k.c: lots of bug fixes
7327 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7329 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7330 #elif, since it is not supported by old compilers.
7331 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7332 couple of expressions in tc-m68k.c.
7334 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7336 * read.c (cons): If NO_RELOC is defined, use it.
7338 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.

7357 * listing.c (debugging_pseudo): Add stabs and stabn as things to
7360 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
7362 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7363 sections starting from zero, rather than making them consecutive.
7364 This makes subsequent reloc calculations easier, esp if the object
7365 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7366 allocate lcomm in .data rather than in .bss. It seems that some
7367 tools can't cope with a non-zero sized bss before linkage.
7369 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7371 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
7372 throughout. That enum no longer means what we thought it meant.

7375 "-mno-688[58]1" options.
7377 * tc-m68k.c: Added CPU32 support.

7390 * Makefile.in (install): if $(tooldir) exists, install as in
7393 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
7395 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
7396 .word is < -32768 or > 32767. The -J flag causes the error to be
7397 ignored. This is to catch over-sized switches generated by gcc on
7398 systems which don't support the broken .word hack.
7399 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
7400 write.c (fixup_segment): check for signed .word overflow if
7401 WARN_SIGNED_OVERFLOW_WORD.
7403 * write.c (fixup_segment): fixed missing parens in expression
7404 checking for byte or word overflow.

7418 * tc-i386.h : new coff defines
7420 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
7422 * input-scrub.c (input_scrub_push): call input_file_begin, not
7424 messages.c (as_perror): print ": " between the passed in error and
7425 the strerror, like perror does.
7427 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

7443 (write_object_file) call fixup_mdeps
7444 (fixup_segment) set fx_subsy to 0.
7445 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
7447 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
7450 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7452 * Makefile.in (LIBS): Include opcode library.
7454 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

7474 tc-i960.c (md_ri_to_chars): Always output bout object file in
7475 little endian byte order (used to use endianness of host).
7477 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7479 * config/tc-m68k.c (init_table): Now const. Always include 68851
7480 data, so that "bc" is available to 68040 cache instructions.
7481 Added "tt0", "tt1", and 68ec030 variants.
7482 (md_assemble): Complain if 68000 (only) and 68881 are specified.
7483 (enum _register): Added TT0, TT1.
7484 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
7485 line number correctly in "internal error" messages. Don't print
7486 architecture-mismatch message for operand errors.
7488 From Colin Smith (colin@wrs.com):
7489 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
7490 than install_operand.
7492 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7494 * listing.c (buffer_line): rewind to the start of include
7495 files, they might be included twice.

7502 one element of a family.
7504 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
7506 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
7507 so that we can assemble hand-written libgcc code.
7509 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7511 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
7512 has already been formatted (but may still contain %-characters).
7515 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
7517 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
7518 written with indirection on the last two operands, which can be
7519 either data or address registers. Added a new operand type 'r'
7520 which accepts either register type. Added '(' to notend stuff in
7521 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

7770 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
7772 * Makefile.in (install): Install into $(tooldir)/bin, since that's
7773 where gcc looks for it.
7775 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
7777 * Makefile.in: Changed some lines to be less confusing for some

7847 * expr.c (operand): if can't work out what sort of operand it is,
7848 then look through FLT_CHARS for a hint.
7850 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
7852 * Makefile.in, configure.in: removed traces of namesubdir,

7856 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
7857 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
7858 copyrights to '92, changed some from Cygnus to FSF.
7860 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7862 * expr.c: If an expression is single comma, then return with
7863 SEG_ABSENT rather than an error - since the sparc front end does
7864 really strange things with things like fbge,a
7866 * as.h: include bfd.h if using many sections
7867 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
7868 local labels didn't work.
7869 * listing.c (list_symbol_table): don't core dump when there's no
7871 * write.c, write.h: call fix_new with the right number of args on

7876 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7878 * app.c: MRI compatibility - allow single quote to start a string.
7879 * as.c: fix typo recently introduced.
7880 * as.h : Don't include aout/reloc.h - it's not right for COFF!
7881 * expr.c: Much rewriting, to accomodate MRI syntax for
7882 expressions. Also easier to read now.
7883 * listing.c: Put back defuns
7884 * read.c: modified to accept MRI syntax, put back listing pseudo
7885 ops so that an assembler built with NO_LISTING ignores list ops
7887 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7888 machine is a SPARC or a 29K.
7889 * config/obj-aout.c: added s_sect pseudo op
7890 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7891 fill in the timestamp.
7892 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7893 anymore, define all the relocs which the tc-<x> bit will use so we
7894 can translate from them to the coff types.
7895 * config/tc-a29k.c: reloc_type isn't ane enum any more
7896 * config/tc-m68k.c: Added NO_RELOC definition.
7898 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
7900 * Makefile.in: put header files before C source for TAGS; remove
7901 references to non-existent syscalls.h.
7903 * read.c, write.c subsegs.c: back out the .bss changes.
7905 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7907 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
7911 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7913 * symbols.c (local_label_name): symbols now start with ^A.
7915 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7916 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7917 generate these sections. .align: will use NOP_OPCODE or 0
7918 for padding. This is just for being nice to the
7921 * expr.c (operand): changed to generate local label "\001L0"
7922 starting with a ^A so that it is recognized as a local label.
7924 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7926 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7927 i/o opcodes - inb, inw, outb and outw. string manipulation with
7928 att syntax - scmp, slod, smov, ssca, ssto.
7930 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7931 to just after .file .
7933 In obj_crawl_symbol_chain() where it tries to put the external
7934 symbols apart, with the condition:
7935 (!S_IS_DEFINED(symbolP) &&
7936 !S_IS_DEBUG(symbolP) &&
7937 !SF_GET_STATICS(symbolP))
7938 it was moving too many symbols out. So I switch it back to the
7940 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7942 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7943 so that we don't use the F_RELFLG which make the linker complain
7944 that somebody has stripped the relocation info.
7946 Also, the AIX ld program require that the relocation table
7947 is sorted by r_vaddr like the standard ATT assembler does.
7949 [he also changed the sizeof(struct ...)'s into the coff
7950 style FOOSZ macros. I'm not sure this is right, but I can't
7951 remember why. xoxorich.]
7953 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

7962 * configure.in: use the new atof-ns32.c for ns32k.
7964 * write.c: comment change only.
7966 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7967 aren't yet integrated.
7969 * tc-i860.[hc]: blew off the dust. Something must still be done
7970 about conflicting relocation types.
7972 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7975 * tc-i960.c, tc-sparc.c: white space and comments only.
7977 * tc-a29k.h: delete duplicate macro definition.
7979 * new file atof-ns32k.c copied from hack's last unreleased gas.
7981 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7983 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7986 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7987 ChangeLog's prior to this are sketchy at best. I have logs.
7988 They just aren't ChangeLogs.
7995 version-control: never
