   4         (append_insn): If mips_optimize == 0, always insert NOP
   5         instructions.  If mips_optimize < 2, don't swap branches.

  12 Fri Jul 23 14:13:25 1993  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
  13
  14         * config/tc-mips.c (prev_insn_unreordered,
  15         prev_prev_insn_unreordered): New static variables.
  16         (append_insn): Don't swap branch instruction if

  19         (s_mipsset): When turning on reordering, set the unreordered
  20         variables.
  21
  22 Fri Jul 23 13:09:44 1993  Ken Raeburn  (raeburn@cambridge.cygnus.com)
  23
  24         * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
  25         are also magic, and have special default flag settings.
  26         (obj_elf_frob_symbol): Since the return value from this function
  27         isn't used, don't bother calling obj_elf_write_symbol_p, since it
  28         doesn't accomplish anything else.
  29
  30         * config/tc-sparc.c (md_section_align): Round up section size only
  31         for a.out format.
  32
  33         * symbols.c: Don't define DEBUG by default.
  34
  35 Thu Jul 22 12:09:41 1993  Ian Lance Taylor  (ian@cygnus.com)
  36
  37         * write.c (fix_new_exp): Handle a O_uminus expression.
  38
  39         * expr.c (expr): Don't let absolute_section override
  40         undefined_section for the return value.
  41
  42         * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
  43         pseudo-op with a poc_handler field of NULL, ignore it and treat it
  44         as an instruction instead.
  45         * config/tc-m88k.c (md_pseudo_table): Add "set" with a NULL
  46         poc_handler field.
  47
  48         * config/tc-h8500.c (md_begin): Use a local variable when
  49         initializing md_relax_table to avoid warnings about modifying a
  50         supposedly const data structure.
  51
  52 Thu Jul 22 10:58:51 1993  Brendan Kehoe  (brendan@lisa.cygnus.com)
  53
  54         * config/obj-aout.c: Only include aout/aout64.h if BFD_ASSEMBLER
  55         is defined.
  56

  58
  59         * configure.in (case ${host}):  Map *-*-sysv4* to gas_host=sysv.
  60         * configure.in (case ${generic_target}):  Add i[34]86-*-sysv4*
  61         case to set obj_format=elf.  Must go before i386-*-sysv* case that
  62         sets obj_format=coffbsd.  Add *-*-sysv4* to *-*-elf and
  63         *-*-solaris case, and move to before *-sysv* case that wants to
  64         set obj_format to coff.
  65         * config/tc-i386.c (i386_operand): Change all 'exp.X_op' to
  66         'exp->X_op'.
  67         * config/tc-i386.c (md_apply_fix):  Fix valp to be 'valueT *' for
  68         BFD_ASSEMBLER case.
  69
  70 Wed Jul 21 12:47:51 1993  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
  71
  72         * config/obj-aout.c: Include aout/aout64.h.
  73         (obj_aout_frob_symbol): Set BSF_DEBUGGING for a constructor
  74         symbol, so that BFD doesn't tamper with the type.
  75
  76         * read.c (read_a_source_file): If NO_PSEUDO_DOT is defined, look
  77         up opcodes as pseudo-ops even if they don't start with '.'.
  78         * config/tc-m88k.h (NO_PSEUDO_DOT): Define.
  79         * config/tc-m88k.c (md_assemble): Removed special pseudo-op
  80         handling.
  81         (md_apply_fix): Set fx_offset to the upper 16 bits of the reloc.
  82         Output the low 16 bits for RELOC_HI16, not the high 16 bits.
  83         * config/obj-coffbfd.c (do_relocs_for): If TC_M88K, set the
  84         r_offset field of the reloc to the fixup offset.
  85         (fixup_segments): If TC_M88K, don't warn about fixup overflows.
  86         * doc/as.texinfo: Minor updates.

  89
  90         * Extensive changes to permit symbols to contain any expression
  91         type and to delay the computation of the expression until the
  92         value is actually needed.  This permits setting symbols to values
  93         calculated based on object code size.  Expressions were changed to
  94         no longer be in a section, to stop the overloading of segment and
  95         expression type that previously occurred.
  96
  97         * as.c (big_section, pass1_section, diff_section, absent_section):
  98         Removed.
  99         (expr_section): Added (used for dummy symbols which hold
 100         intermediate expression values).
 101         (perform_an_assembly_pass): Create expr_section, do not create the
 102         sections now removed.
 103         * as.h (segT): Removed SEG_ABSENT, SEG_PASS1, SEG_BIG, and
 104         SEG_DIFFERENCE.  Added SEG_EXPR.
 105         (SEG_NORMAL): Corresponding changes.
 106         * subsegs.c (seg_name, subsegs_begin): Changed accordingly.
 107         * write.c (write_object_file): Ditto.

 113
 114         * expr.h (operatorT): Moved in from expr.c, added some values.
 115         (expressionS): Added X_op field, removed X_seg field; renamed
 116         X_subtract_symbol to X_op_symbol.
 117         * expr.c: Extensive changes to assign expression types rather than
 118         sections and to simplify the parsing.
 119         * write.c (fix_new_internal): New static function.
 120         (fix_new): Removed sub_symbol argument.
 121         (fix_new_exp): New function, takes expression argument.
 122         * write.h: Prototype changes for fix_new and fix_new_exp.
 123         * cond.c (s_if): Changed accordingly.
 124         * read.c (s_lsym, pseudo_set, emit_expr, parse_bitfield_cons,
 125         parse_repeat_cons, get_segmented_expression,
 126         get_known_segmented_expression, get_absolute_expression): Ditto.
 127         * symbols.c (resolve_symbol_value, S_GET_VALUE, S_SET_VALUE):
 128         Ditto.

 138         * config/tc-h8500.c (parse_exp, skip_colonthing, parse_reglist,

 159         * config/tc-mips.c (md_assemble, append_insn, gp_reference,
 160         macro_build, macro, my_getExpression): Ditto.  Also removed
 161         get_optional_absolute_expression; just use get_absolute_expression
 162         instead.
 163         * config/tc-ns32k.c (get_addr_mode, evaluate_expr, convert_iif,

 179
 180 Mon Jul 19 15:21:20 1993  Ken Raeburn  (raeburn@rtl.cygnus.com)
 181

 183         (previous_section, previous_subsection): New vars.
 184         (obj_elf_section): Save current place in case DWARF code wants us
 185         to pop back to it.  Handle unquoted section name as well as quoted
 186         section name.  Don't crash on invalid strings.
 187         (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
 188         "4byte".
 189
 190         * config/obj-elf.h: Don't include struc-symbol.h.
 191         (obj_elf_frob_symbol): Declare arg as struct symbol *.
 192
 193         * tc-sparc.h (LOCAL_LABEL) [OBJ_ELF]: Local labels can start with
 194         "L" or "_.L_".
 195
 196         * write.c (write_relocs): New function, split off from

 207
 208         * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
 209         calculating opP->isiz; this permits the expression size to be
 210         determined as well, later on.
 211
 212         * expr.c (clean_up_expression): Don't cancel the subtraction of

 217
 218 Mon Jul 19 12:35:39 1993  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 219
 220         * config/tc-m68k.c (m68k_ip, case AINDX): Add 6 to operand
 221         expression (to take the pc-rel instruction itself into account)
 222         before using the expression, instead of after.
 223
 224 Fri Jul 16 08:56:04 1993  Ian Lance Taylor  (ian@cygnus.com)
 225
 226         * read.c (float_cons): Simplified parsing logic.  If
 227         REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.
 228
 229         * symbols.c (colon): Rather than a special case for TC_HPPA,
 230         use new macro tc_frob_label.
 231         * config/tc-hppa.h (tc_frob_label): Define.
 232
 233         * config/tc-mips.c: Many changes to support simple assembler
 234         optimization.
 235         (insn_label, prev_insn, prev_prev_insn, dummy_opcode,
 236         prev_insn_valid, prev_insn_frag, prev_insn_where,
 237         prev_insn_fixp, prev_insn_is_delay_slot): New static
 238         variables.

 241         (mips_define_label): New global function.
 242         (md_pseudo_table): For "ascii", "asciz", "asciiz", call
 243         s_stringer.  Changed argument to float_cons from 0 or 1 to 'f'
 244         or 'd'.  For "space" call s_mips_space.
 245         (md_begin): Call mips_no_prev_insn.
 246         (append_insn): Only insert necessary NOP instructions.
 247         (macro): Call mips_emit_delays before setting mips_noreorder.
 248         Increment and decrement mips_noreorder rather than using
 249         save_reorder_condition.  Don't bother to use noreorder in
 250         M_L_DOB and M_L_DAB, since append_insn will not insert a NOP.
 251         (md_atof): Handle floating point numbers correctly for both
 252         big and little endian targets.
 253         (s_align, s_cons): Call mips_align rather than frag_align.
 254         (s_change_seg, s_cons): Call mips_emit_delays.
 255         (s_float_cons): Let float_cons do the work.
 256         (s_mipsset): Call mips_emit_delays when setting noreorder.
 257         * config/tc-mips.h (tc_frob_label): Define to be
 258         mips_define_label.
 259
 260         * config/obj-ecoff.c (ecoff_build_symbols, ecoff_build_procs,
 261         ecoff_frob_files): Consistently use S_GET_VALUE rather than
 262         bfd_asymbol_value.  Warn if taking difference of symbols in
 263         different segments.
 264
 265 Thu Jul 15 11:51:03 1993  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 266
 267         * config/obj-ecoff.c (ecoff_frob_file): Discard all open scopes,
 268         with a warning.
 269
 270         * config/obj-coffbfd.c (fixup_segment): If TC_M88K, don't adjust
 271         by md_pcrel_from if we are relocating against a symbol (we still
 272         need md_pcrel_from for a PC relative relocation within the same
 273         file).
 274         * config/tc-m88k.c (md_pcrel_from): Corrected return value.
 275         (omagic): Removed unused variable.
 276
 277         * Preliminary support for m88k-coff.
 278         * configure.in (m88k-*-coff*): New target.  Use coffbfd and
 279         m88kcoff.
 280         * config/m88kcoff.mt: New file.
 281         * read.c (lex_type): New macro LEX_AT to set lex type of '@'.
 282         (pseudo_set): Handle difference of symbols in different fragments
 283         by saving the entire expression as the value of the symbol.
 284         * symbols.c (resolve_symbol_value): Resolve difference
 285         expressions.
 286         * config/obj-coffbfd.c (obj_pseudo_table): If TC_M88K, accept
 287         "sdef" as a synonym for "def".
 288         * config/obj-coffbfd.h: If TC_M88K, include coff/m88k.h and set
 289         TARGET_FORMAT.
 290         (S_IS_LOCAL): Any symbol which includes \001 in the name is local.
 291         * config/tc-m88k.c, config/tc-m88k.h: Numerous changes to bring
 292         m88k port up to date, and to add COFF support.
 293
 294 Wed Jul 14 15:09:32 1993  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 295
 296         * Removed sy_forward and replaced it with an undefined expression
 297         as the value of a symbol.
 298         * struc-symbol.h (struct symbol): Removed sy_forward field.  Added
 299         sy_resolved and sy_resolving single bit fields.
 300         * symbols.c (symbol_new): Don't initialize sy_forward field.
 301         (resolve_symbol_value): New function to adjust symbol value by
 302         fragment address, using recursion to resolve forward symbols.
 303         * symbols.h: Added prototype for new function.
 304         * read.c (pseudo_set): Set symbolP->sy_value to an undefined
 305         expression rather than setting symbolP->sy_forward.

1311         (md_assemble): Set gp size of output BFD.
1312         (gp_reference): New function; returns 1 if expression can be

1328         the output file.
1329
1330         * doc/as.texinfo: Don't use @value in node names for the moment;
1331         references don't appear to work right.
1332
1333         * as.h (const, volatile): Put these definitions back, and use
1334         them.
1335
1336         * doc/as.texinfo: First pass at using new texinfo features --
1337         variables, conditional tests.  Far from complete.

1340
1341         * read.c: Temporary hack to handle some 64-bit constants.  This

1362
1363         * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
1364         the bottom (make expands variables in dependencies when the

1366
1367         * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
1368         a29k .bss section; the mondfe program doesn't like it.

1377
1378         * doc/none.m4: Define Z8000.
1379         * doc/Makefile.in (as-*.texinfo): Refer to $(srcdir).  Remove the
1380         texinfo file before recreating it.
1381         (TEXI2DVI): Need to set TEXINPUTS if "make as.dvi" is to work in

1392         number.

1397         * read.c (potable): Change .app-file to .appfile.
1398
1399         * config/ho-decstatn.h: Renamed from ho-decstation.h.
1400         * configure.in: Adjusted.
1401
1402         * config/obj-bfd-sunos.*: Unused; deleted.
1403
1404         * Makefile.in (version.c, vers-stamp): Deleted.
1405         (config.h): Define GAS_VERSION.
1406         * as.c (version_string): Deleted declaration.
1407         (main): Look for GAS_VERSION instead.
1408
1409         * doc/as.texinfo: Updated description of -a* (listing) options,
1410         and describe how to pass them through from gcc.
1411
1412         * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
1413         process relocs if there aren't any relocs to process.  Avoids
1414         malloc/free bug on SCO too.
1415
1416         * as.h: Move local include files below system include files, to
1417         avoid some redefinition complaints on some systems.
1418         (const, volatile): Don't need these conditionally defined if we
1419         use CONST and VOLATILE from ansidecl.h.
1420         (seg_name): Use CONST, not const.
1421
1422 Fri Mar 26 10:22:04 1993  Ian Lance Taylor  (ian@cygnus.com)
1423

1426 Thu Mar 25 08:59:14 1993  Ian Lance Taylor  (ian@cygnus.com)
1427

1429         (fixup_segment): Add a29k special case; the linker is not prepared
1430         to see a segment offset here.
1431
1432         * app.c (do_scrub_next_char): Added new state, 10, modifying state
1433         9 to only keep a space in between identifier characters.
1434

1436
1437         * Makefile.in: add dvi target; as-$(config).texinfo might live in
1438         srcdir, might be in objdir.
1439
1440         * doc/Makefile.in: dvi depends on as.dvi

1460
1461         * app.c (do_scrub_next_char): Added new state, 9, to avoid
1462         dropping a space immediately following an identifier.
1463         * expr.c, write.c: Rewrote assert expressions to not use multiple
1464         lines; I don't think that can be done portably.
1465         * config/tc-mips.c (macro): Use $AT if target register is zero in
1466         load instruction, which it can be for a floating point load.
1467

1473         symbol table and values right.
1474         * config/tc-mips.h (LOCAL_LABEL): If OBJ_ECOFF, any label starting
1475         with $L is local.
1476         * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
1477         by the section vma.
1478
1479         * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
1480         z8k-opc.h, not z8k.h.
1481
1482         * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
1483         symbol.

1486
1487         * configure.in: recognize sparc-sun-solaris2* instead of -solaris2

1498         (ALL_CFLAGS): No longer define TARGET_CPU.
1499
1500         * Makefile.in (check): Print a message, instead of quitting
1501         silently.
1502
1503         * as.c (main): Don't catch any signals, for now.
1504
1505         * version.c: Deleted.

1533         support.
1534
1535         * config/tc-mips.h (TARGET_FORMAT): Define based on OBJ_AOUT vs.
1536         OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
1537         (struct loc, struct proc, struct file): Moved to tc-mips.c within
1538         #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
1539         * config/tc-mips.c: Rearranged for ECOFF support.  Added
1540         prototypes for all static functions.  Moved existing minimal
1541         debugging format support info #ifndef OBJ_ECOFF blocks.
1542         (macro_build_lui): Eliminated sign_extend argument, because ECOFF
1543         does not support a non sign extended high 16 bits reloc.  Adjusted
1544         all callers accordingly.
1545         (tc_get_register): Renamed from get_register, and made non-static.
1546
1547         * config/mips-big.mt, config/mips-lit.mt: New files.  Define
1548         TARGET_BYTES_BIG_ENDIAN and TARGET_BYTES_LITTLE_ENDIAN,

1551         (mips-*-ultrix*, mips-*-irix*, mips-*-ecoff): New targets, using

1576         read.c, config/obj-ieee.c, config/obj-tcm88k.c: Not any of these
1577         places.

1588
1589         Patches from Eric Youngdale:
1590         * make-gas.com: Find obstack.obj if it's not in the current
1591         directory.
1592         * read.c (s_ignore): Don't declare is_end_of_line.  It's
1593         redundant, and triggers a VMS gcc compiler bug.
1594
1595         * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1596         current segment as an argument.  (Ignored in all cases but VMS.)
1597         All callers and definitions changed.
1598
1599 Tue Mar  2 11:56:19 1993  Ian Lance Taylor  (ian@cygnus.com)
1600
1601         * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING
1602         case compile again.
1603
1604 Tue Mar  2 08:53:34 1993  Ken Raeburn  (raeburn@cygnus.com)
1605
1606         * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,
1607         so "~0x80" won't be rejected.
1608
1609         * config/obj-elf.c: No longer include elf/reloc.h.
1610         (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
1611         (obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out
1612         routines.
1613         (obj_elf_xstab): New routine.
1614         (obj_elf_set_size): Call as_warn, not fprintf.  Pass desired
1615         argument to s_ignore.  Put "#if 0" around unused code.
1616         (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
1617         Call elf_xstabs for .stabs and .xstabs operators.
1618
1619         * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
1620
1621         * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
1622         present.
1623
1624         * configure.in: mips-bsd configuration was missing format spec.
1625         Should use aout.
1626
1627         * Makefile.in (Makefile): Depends on configure.in.
1628
1629         * config/tc-mips.c (append_insn): Don't check for alignment of
1630         frag in memory; alignment of instructions in section is a separate
1631         matter.
1632
1633         * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
1634         C availability.
1635
1636         * listing.h: Always provide function declarations, not macros, so
1637         pcc won't lose.

1953           g++ compiler is incapable of doing this.
1954         * tc-vax.c: Add '1' option for backward compatibility with older GCC
1955           versions.
1956         * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
1957         * input-scrub.c (as_where): Fix bug where as would crash if we did not
1958           have the name of the source file yet.
1959         * config/ho-vms.h: define HO_VMS, not HO_VAX.

1961 Mon Jan  4 05:17:26 1993  Ken Raeburn  (raeburn@cygnus.com)
1962
1963         * read.c (s_data): Always use "data_section", since it'll map to
1964         SEG_DATA or SEG_E1 if needed.
1965         (s_lcomm): Likewise with bss_section.
1966         (s_fill): Use memset, not bzero.
1967
1968 Thu Dec 31 04:29:27 1992  Ken Raeburn  (raeburn@kr-pc.cygnus.com)
1969
1970         * read.c: Deleted some code under "#ifdef DONTDEF" that was for
1971         handling GDB symbol table data.

1985         (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
1986         (segment_name) If BFD_ASSEMBLER, look up BFD section name;
1987         otherwise, use seg_name array.
1988         (seg_name): Declare only if not BFD_ASSEMBLER.
1989         (section_alignment): Declare only if not BFD_ASSEMBLER.
1990         (big_section, reg_section, pass1_section, diff_section,
1991         absent_section, text_section, data_section, bss_section): If
1992         BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
1993         mapping to segT enum values.
1994         (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
1995         if these are used or defined, if BFD_ASSEMBLER.

2002         NO_STDARG.
2003         (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
2004         declare with format attribute for -Wformat checking.
2005
2006 Wed Dec 30 10:18:57 1992  Ian Lance Taylor  (ian@cygnus.com)
2007
2008         * app.c, config/tc-*.c: Don't include read.h, since it is already
2009         included by as.h.
2010
2011         * These are based on patches from Minh Tran-le
2012         <mtranle@paris.intellicorp.com>.
2013         * configure.in (i[34]86-ibm-aix*): Accept i486 for host.  Use
2014         obj_format coffbfd and gas_target i386coff for target.
2015         (i[34]86-*-isc*): New host (uses sysv).
2016         * config/i386aix.mt: Removed (no longer used).
2017         * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2018         (MINUS_G): Removed.
2019         (LDFLAGS): Added, defined as -shlib.
2020         * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2021         * config/te-sco386.h (LOCAL_LABEL): Don't define.
2022         (DOT_LABEL_PREFIX): Define.
2023         * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
2024         name rather than L0\001.
2025         * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
2026         local_bss_counter.
2027         * symbols.c, symbols.h (local_bss_counter): Removed.
2028         * write.c (write_object_file): bss no longer uses
2029         local_bss_counter.  Pass correct data and bss size to
2030         VMS_write_object_file.
2031         * config/obj-vms.c (VMS_write_object_file): Accept bss size as
2032         argument, rather than using local_bss_counter.

2036         (size_section): Restored sanity check.
2037         (do_relocs_for): Base section address on s_paddr rather than
2038         computing it.  Adjust a29k R_IHIHALF special case to account for
2039         section paddr (used to require paddr to be zero).  If there are no
2040         reclos, set s_relptr to 0.  Set relocation size in object_headers.
2041         (fill_section): Always set s_vaddr here, removing
2042         ZERO_BASED_SEGMENTS case.  Force s_scnptr for bss to 0.  Don't set
2043         NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2044         Set STYP_INFO for .comment.
2045         (coff_header_append): Use object headers and H_{SET,GET}_* macros.
2046         Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
2047         (crawl_symbols): Handle 8 character section name correctly.  Use

2049         (do_linenos_for): Set lineno size in object_headers.
2050         (write_object_file): Use H_{SET,GET}_* macros.  Don't bother to
2051         set s_vaddr here.  If string_byte_count remains 4, set it back to
2052         0, and only write strings out if there are some.  Call
2053         fill_section before do_relocs_for and do_linenos_for.
2054         (obj_coff_section): Handle optional quoted second argument giving
2055         section characteristics.
2056         (obj_coff_bss): Added to handle .bss.
2057         (obj_coff_ident): Added to handle .ident (puts string in .comment
2058         section).
2059         (obj_coff_lcomm): Put common symbols in .bss, not .data.
2060         (fixup_mdeps): Change to segment.  Call frag_wane after
2061         md_convert_frag.
2062         (fixup_segment): Explicitly check S_IS_COMMON before making 386
2063         adjustment (already happened only for common symbols, but this is
2064         clearer).
2065         * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
2066         * config/tc-i386.c (s_bss): Don't use if I386COFF.
2067         (md_pseudo_table): Ignore .optim and .noopt.
2068         (tc_coff_sizemachdep): New function.
2069         * config/tc-i386.h (REVERSE_SORT_RELOCS): Undef, for SVR3
2070         compatibility.
2071         (LOCAL_LABEL): Removed definition.
2072         (DOT_LABEL_PREFIX): Defined.

2077         (do_scrub_next_char): For \", return " not '.
2078         (symbol_chars): Now const.
2079
2080         * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2081         and "0b".  If LOCAL_LABELS_DOLLAR, check for "0$".
2082
2083         * config/obj-coff.h: Don't use #elif.
2084
2085         * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2086         have it.  (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

2088 Wed Dec 16 12:12:33 1992  Ian Lance Taylor  (ian@cygnus.com)
2089

2105
2106         * listing.c: Call xmalloc, not malloc; don't declare malloc.
2107
2108         * Changes to support SCO 3.2v4:
2109         * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
2110         SEG_BSS, fill with NOP_OPCODE.
2111         * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
2112         * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
2113         using ZERO_BASED_SEGMENTS.
2114         (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
2115         never set segment address for SEG_E2 (.bss) and don't write out
2116         SEG_E2 contents.  Set .init and .fini sections to STYP_TEXT.
2117         (obj_coff_endef): Don't merge labels or symbols awaiting forward
2118         definitions, and don't merge tags with non-tags.  Check for .bf
2119         rather than just checking whether the second character is b and
2120         the third character is f.
2121         (obj_coff_val): gcc can generate values which we don't handle
2122         correctly; discard information for now, since it only affects the
2123         debugging information.
2124         (tag_find_or_name): Don't insert tags in the symbol table.
2125         (yank_symbols): Don't merge labels.
2126         (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
2127         already defined.  Fill subsegments with NOP_OPCODE, not 0.  Don't
2128         set segment address if ZERO_BASED_SEGMENTS.
2129         (obj_coff_section): Accept and ignore a trailing quoted string, as
2130         used in AT&T i386 syntax.
2131         (fixup_segment): Take segment as argument.  On the i386, adjust PC
2132         relative addends by the segment vaddr.
2133         * tc-i386.h: Define SUB_SEGMENT_ALIGN.
2134         * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
2135         * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

2272         could be doing emulation.
2273
2274 Thu Nov 19 11:47:19 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
2275
2276         z8000 documentation
2277         * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
2278         all modified.

2285
2286         * read.h: added extern declarations for comment_chars,
2287         line_comment_chars, and line_separator_chars.
2288         read.c, app.c: removed definitions of comment_chars,
2289         line_comment_chars, and line_separator_chars.
2290
2291         * tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
2292         still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
2293         the register name.
2294         (insert_reg): put REGISTER_PREFIX before register names before
2295         putting them in the symbol table.
2296         * tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not
2297         M68KCOFF.
2298
2299         * obj-coffbfd.c (fill_section): set STYP_NOLOAD bit for .bss
2300         section.
2301
2302         * atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
2303         comment_chars, line_comment_chars and line_seperator_chars
2304         consistently const, and always initialized them.  Included read.h.
2305
2306 Thu Nov  5 17:55:41 1992  Jim Wilson  (wilson@sphagnum.cygnus.com)
2307
2308         * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
2309         constant will not fit in an immediate field.
2310         (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
2311
2312 Wed Nov  4 07:50:46 1992  Ken Raeburn  (raeburn@cygnus.com)
2313
2314         * obj-coff.c (callj_table): Delete global variable.
2315         (obj_emit_relocations): Define it locally here, and only if
2316         TC_I960 is defined.
2317
2318         * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.
2319         (m68k_ip): Don't warn about bignum used as float bit-pattern.
2320
2321         * obj-coff.c: Replaced ANSI and non-ANSI function declarations
2322         with a single set using PARAMS macro.
2323
2324         * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length
2325         of 2.
2326
2327         * tc-i960.c: Missed a couple of 0->NO_RELOC conversions.
2328
2329         * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
2330         so widening works consistently.
2331
2332 Wed Oct 28 08:52:34 1992  Ken Raeburn  (raeburn@cygnus.com)
2333
2334         * version.c: Put conditional "const" before version_string, not
2335         before dummy function for VMS.  Now version 1.91.03.
2336
2337         * app.c (do_scrub_next_char): Need double-\ before `000' to show
2338         printed rep of null character.

2340 Fri Oct 23 14:40:38 1992  Ian Lance Taylor  (ian@cygnus.com)
2341
2342         * obj-coffbfd.c (write_object_file): check return value of
2343         bfd_close_all_done.
2344
2345 Tue Oct 20 12:18:08 1992  Ian Lance Taylor  (ian@cygnus.com)
2346
2347         * Support for i386-sysv.
2348         obj-coffbfd.c (do_relocs_for, write_object_file): set segment
2349         addresses to reasonable sizes.  New define ZERO_BASED_SEGMENTS can
2350         be used to set them all to zero as was done before.
2351         (fill_section): segment addresses now set in write_object_file.
2352         (fill_section): Don't set STYP_NOLOAD for .bss section.
2353         (fixup_segment): 386 uses strange common symbol format.
2354         tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
2355         compatibility with SVR3.2 linker.
2356         * configure.in: i386-sysv and i386-sco use coffbfd.
2357
2358         * app.c (do_scrub_next_char): discard whitespace after a label.
2359

2363         hosts, use the sysv configuration for solaris2
2364
2365 Mon Oct  5 09:28:57 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
2366
2367          fix i960+non-bfd coff bit rot.
2368         * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
2369         support for C source listings. (obj_coff_endef): look in the right
2370         part of the symbol for the symbol name
2371
2372         * tc-m68k.c (get_num): make it work for all segments, not just the
2373         first three.
2374
2375 Mon Oct  5 03:30:36 1992  Mark Eichin  (eichin at tweedledumber.cygnus.com)
2376
2377         * configure.in: recognize i386-*-bsd emulation.

2388 Tue Sep 29 10:51:55 1992  Ian Lance Taylor  (ian@cygnus.com)
2389
2390         * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2391         #elif, since it is not supported by old compilers.
2392         ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2393         couple of expressions in tc-m68k.c.
2394
2395 Mon Sep 28 21:18:24 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
2396
2397         * read.c (cons): If NO_RELOC is defined, use it.
2398
2399         * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2400
2401 Fri Sep 25 18:18:52 1992  Ian Lance Taylor  (ian@cygnus.com)
2402
2403         * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2404         local labels to start with a .) and set REGISTER_PREFIX to %.
2405         tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2406
2407 Fri Sep 25 17:53:43 1992  John Gilmore  (gnu@cygnus.com)
2408
2409         * messages.c:  Comment changes.
2410
2411 Fri Sep 25 14:12:58 1992  Ken Raeburn  (raeburn@kyriath.cygnus.com)
2412
2413         * as.h: Test if __STDC__ is defined only, don't test its value.
2414         * messages.c: If __STDC__ is not defined, define NO_STDARG.
2415
2416 Thu Sep 24 12:42:32 1992  Brendan Kehoe  (brendan@rtl.cygnus.com)
2417
2418         * listing.c (debugging_pseudo): Add stabs and stabn as things to
2419         ignore.
2420
2421 Tue Sep 22 13:02:07 1992  Sean Eric Fagan  (sef@cygnus.com)
2422
2423         * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2424         sections starting from zero, rather than making them consecutive.
2425         This makes subsequent reloc calculations easier, esp if the object
2426         format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2427         allocate lcomm in .data rather than in .bss.  It seems that some
2428         tools can't cope with a non-zero sized bss before linkage.
2429
2430 Tue Sep 22 15:10:51 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
2431
2432         * tc-m68k.c: Replace "enum m68k_architecture" with "int"
2433         throughout.  That enum no longer means what we thought it meant.
2434
2435         * tc-m68k.c (md_assemble, md_parse_option): Handle new
2436         "-mno-688[58]1" options.
2437
2438         * tc-m68k.c: Added CPU32 support.

2441
2442         * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
2443
2444 Tue Sep 15 17:25:05 1992  Jim Wilson  (wilson@sphagnum.cygnus.com)
2445
2446         * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
2447         Change LIBDEPS dependence to LIBS.

2450
2451         * Makefile.in (install): if $(tooldir) exists, install as in
2452         $(tooldir)/bin.
2453
2454 Sun Sep 13 20:30:10 1992  Ian Lance Taylor  (ian@cygnus.com)
2455
2456         * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2457         .word is < -32768 or > 32767.  The -J flag causes the error to be
2458         ignored.  This is to catch over-sized switches generated by gcc on
2459         systems which don't support the broken .word hack.
2460         as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2461         write.c (fixup_segment): check for signed .word overflow if
2462         WARN_SIGNED_OVERFLOW_WORD.
2463
2464         * write.c (fixup_segment): fixed missing parens in expression
2465         checking for byte or word overflow.
2466
2467         * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
2468         obj-coffbfd.c (fixup_segment): check for signed .word overflow if
2469         WARN_SIGNED_OVERFLOW_WORD.
2470
2471         * obj-coffbfd.c (fixup_segment): fixed missing parens in
2472         expression checking for byte or word overflow.
2473
2474 Fri Sep 11 10:21:04 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
2475
2476         Support for i386 coff
2477         * obj-coffbfd.h : added stuff
2478         * tc-i386.c (tc_coff_fix2rtype): new function
2479         * tc-i386.h : new coff defines
2480
2481 Thu Sep 10 09:23:15 1992  Ian Lance Taylor  (ian@cygnus.com)
2482
2483         * input-scrub.c (input_scrub_push): call input_file_begin, not
2484         input_scrub_begin.
2485         messages.c (as_perror): print ": " between the passed in error and
2486         the strerror, like perror does.
2487
2488 Wed Sep  9 11:06:25 1992  Ian Lance Taylor  (ian@cygnus.com)
2489
2490         * Makefile.in: use gas_target instead of modifying target_cpu.
2491         From Steve Chamberlain:
2492         Makefile.in: Handle m68*-*-coff*.
2493         read.c, read.h: add mult argument to s_space
2494
2495         * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
2496          Motorola and MIT syntax; gas can now assemble either type of
2497          file.
2498         tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
2499         From Steve Chamberlain:
2500         m68kcoff.mt: for m68k COFF.
2501         obj-coffbfd.c: (fixup_mdeps) added
2502          (size_section) removed bad sanity check
2503          (fill_section) added rs_machine_dependent case
2504          (write_object_file) call fixup_mdeps
2505          (fixup_segment) set fx_subsy to 0.
2506         obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
2507          handle m68k.
2508         tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
2509          pseudo ops.
2510
2511 Tue Sep  8 17:10:58 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)

2535         tc-i960.c (md_ri_to_chars): Always output bout object file in
2536         little endian byte order (used to use endianness of host).
2537
2538 Tue Aug 25 15:50:48 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
2539
2540         * config/tc-m68k.c (init_table): Now const.  Always include 68851
2541         data, so that "bc" is available to 68040 cache instructions.
2542         Added "tt0", "tt1", and 68ec030 variants.
2543         (md_assemble): Complain if 68000 (only) and 68881 are specified.
2544         (enum _register): Added TT0, TT1.
2545         (m68k_ip, cases '3' and 't'): Handle new operand type codes.  Pass
2546         line number correctly in "internal error" messages.  Don't print
2547         architecture-mismatch message for operand errors.
2548
2549         From Colin Smith (colin@wrs.com):
2550         * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
2551         than install_operand.
2552

2554
2555         * listing.c (buffer_line): rewind to the start of include

2559
2560 Mon Aug 24 12:45:43 1992  Ian Lance Taylor  (ian@cygnus.com)
2561
2562         * Makefile.in: defined TARGET_CPU for C code so that it can choose
2563         one element of a family.
2564
2565         * tc-m68k.c: use TARGET_CPU to choose default cpu type.
2566
2567         * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
2568         so that we can assemble hand-written libgcc code.
2569
2570 Fri Aug 21 14:38:44 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
2571
2572         * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
2573         has already been formatted (but may still contain %-characters).
2574         (as_bad): Likewise.
2575
2576 Wed Aug 19 11:20:59 1992  Ian Lance Taylor  (ian@cygnus.com)
2577
2578         * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2579         written with indirection on the last two operands, which can be
2580         either data or address registers.  Added a new operand type 'r'
2581         which accepts either register type.  Added '(' to notend stuff in
2582         tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

2593         * write.c: Merged some declarations, using PARMS macro.
2594         (text_frag_root, data_frag_root, bss_frag_root, text_last_frag,
2595         data_last_frag): No longer static.
2596         (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
2597         defined, call it.  Change segments before calling fixup_segment.

2599
2600         * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite

2922
2923         * expr.c: If an expression is single comma, then return with
2924         SEG_ABSENT rather than an error - since the sparc front end does

2926
2927         * as.h: include bfd.h if using many sections
2928         * expr.c: LOCAL_LABELS_FB had been changed to lower case - so

2943         expressions. Also easier to read now.
2944         * listing.c: Put back defuns
2945         * read.c: modified to accept MRI syntax, put back listing pseudo
2946         ops so that an assembler built with NO_LISTING ignores list ops
2947         rather than pukes.
2948         * write.c, write.h: fixs - only keep a reloc type in a fix if the target
2949         machine is a SPARC or a 29K.
2950         * config/obj-aout.c: added s_sect pseudo op
2951         * config/obj-coffbfd.c: lints, set the filehdr flags right and
2952         fill in the timestamp.
2953         * config/obj-coffbfd.h: Since we don't include aout/reloc.h
2954         anymore, define all the relocs which the tc-<x> bit will use so we
2955         can translate from them to the coff types.
2956         * config/tc-a29k.c: reloc_type isn't ane enum any more
2957         * config/tc-m68k.c: Added NO_RELOC definition.

2960
2961         * Makefile.in: put header files before C source for TAGS; remove
2962           references to non-existent syscalls.h.
2963
2964         * read.c, write.c subsegs.c: back out the .bss changes.
2965
2966         * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
2967
2968         * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
2969
2970         * a.out.h: removed.

2972 Fri Feb 21 01:08:48 1992  Minh Tran-Le (TRANLE@INTELLICORP.COM)
2973
2974         * symbols.c (local_label_name): symbols now start with ^A.
2975
2976         * read.c, subsegs.c, write.c obj-coff.c: added handling of
2977           `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
2978           generate these sections.  .align: will use NOP_OPCODE or 0
2979           for padding. This is just for being nice to the
2980           disassembler.
2981
2982         * expr.c (operand): changed to generate local label "\001L0"
2983           starting with a ^A so that it is recognized as a local label.
2984
2985         * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
2986
2987         * tc-i386.c: tc-i386.c: added handling of the following opcodes:
2988           i/o opcodes - inb, inw, outb and outw.  string manipulation with
2989           att syntax - scmp, slod, smov, ssca, ssto.
2990
2991         * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
2992           to just after .file .
2993
2994           In obj_crawl_symbol_chain() where it tries to put the external
2995           symbols apart, with the condition:
2996             (!S_IS_DEFINED(symbolP) &&
2997              !S_IS_DEBUG(symbolP) &&
2998              !SF_GET_STATICS(symbolP))
2999           it was moving too many symbols out. So I switch it back to the
3000           condition:
3001             (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3002
3003           In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3004           so that we don't use the F_RELFLG which make the linker complain
3005           that somebody has stripped the relocation info.
3006
3007           Also, the AIX ld program require that the relocation table
3008           is sorted by r_vaddr like the standard ATT assembler does.
3009
3010           [he also changed the sizeof(struct ...)'s into the coff
3011           style FOOSZ macros.  I'm not sure this is right, but I can't
3012           remember why.  xoxorich.]

3015
3016         * Makefile.in, configure.in, doc: use the doc.  Build it, install
3017           it, clean it, etc.
3018
3019 Tue Feb 18 02:21:25 1992  K. Richard Pixley  (rich at cygnus.com)
3020
3021         * read.c: white space and comments only.
3022
3023         * configure.in: use the new atof-ns32.c for ns32k.
3024
3025         * write.c: comment change only.
3026
3027         * tc-m88k.[hc]: pulled in from hack's unfinished work.  These
3028           aren't yet integrated.
3029
3030         * tc-i860.[hc]: blew off the dust.  Something must still be done
3031           about conflicting relocation types.
3032
3033         * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3034           real thing.
3035
3036         * tc-i960.c, tc-sparc.c: white space and comments only.
3037
3038         * tc-a29k.h: delete duplicate macro definition.
3039
3040         * new file atof-ns32k.c copied from hack's last unreleased gas.

3043
3044         * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3045           rather than abort.
3046
3047         * nearly everything.  flush ChangeLog, package as gas-1.92.1.
3048           ChangeLog's prior to this are sketchy at best.  I have logs.
3049           They just aren't ChangeLogs.
