1492 * config/tc-hppa.c: Eliminate all uses of fx_addnumber.
1493 (tc_gen_reloc): Simplify. It's no longer necessary to set a
1494 reloc's addend field to zero for function symbols.
1495 (md_apply_fix): Simplify. For fixups which will require a SOM
1496 reloc, just clear out the necessary bits in the output file.
1498 Fri Oct 14 19:06:46 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1500 * Makefile.in (BISON): Use bison -y, not bison.

1514 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
1516 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
1517 it's better to use the one in libiberty.
1519 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1521 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
1522 change; it breaks the rs6000 support, and doesn't seem to be
1525 Wed Oct 12 11:56:50 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
1527 * config/tc-i386.h,te-netbsd532.h (TARGET_FORMAT): Changed to

1533 rather than explicitly adding the frag address.
1534 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark

1536 used to be added by coff_add_linesym, removed Oct 7.
1537 (coff_adjust_section_syms): Ignore sections with no seginfo.
1539 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1541 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a
1542 "stage" symlink to the appropriate stage* directory, and use it
1543 instead in the -B options.
1544 (comparison): Revert yesterday's change.

1551 Tue Oct 11 15:24:00 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
1553 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
1554 for an embedded PIC switch expression, since the definition of
1555 S_IS_LOCAL was changed.
1557 Tue Oct 11 15:05:11 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
1559 * Makefile.in (comparison): When comparing as.new or gasp.new, try
1560 running the binary through sed to avoid differences due to
1561 "stage1" or "stage2" having been written into the binary.
1563 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
1565 ELF symbol size handling, based on code from Eric Youngdale:
1566 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an

1573 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
1575 (obj_elf_size): Deleted unused code. If size is non-reducible
1576 expression, allocate some storage for the sy_obj field and copy
1578 (elf_frob_symbol): New function. Computes sizes, calls
1579 ecoff_frob_symbol if appropriate.
1581 * write.c (fixup_segment): For i386 elf and coff (for now), don't
1582 add in value of symbol from another defined section of the file.
1584 Fri Oct 7 17:54:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

1628 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
1630 (diststuff): New target; builds DISTSTUFF.
1631 (realclean): Separate target, depend on clean and distclean, then
1633 * make-gas.com: Deleted.

1636 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
1638 (i386_operand): Don't look up section symbol for
1640 (reloc): Always permit return of 8- and 16-bit relocation types.
1641 Add a space after "pc-relative" in the error message.
1642 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
1643 BFD_RELOC_386_GOTOFF relocs.

1647 (TC_VALIDATE_FIX): New macro -- call it.
1648 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.

1653 * write.h (struct fix): Added new bitfield fx_plt, for fixups
1654 referring to PLT entries.
1655 * write.c (fix_new_internal): Initialize fx_plt to zero.
1656 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
1657 Don't adjust fx_offset by frag address, since S_GET_VALUE now
1658 includes the frag address.
1659 (fixup_segment): Changed local var PCREL to type int, added PLT.
1660 If PC-relative fixup refers to a PLT entry for a symbol in the
1661 current section, don't reduce it.

1683 Show fx_r_type and fx_addsy fields.
1685 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1687 * configure.in: Set bfd_gas for all sparc targets in one place,
1688 instead of separately for each. Correctly handle user-supplied
1689 "--enable-bfd-gas" option.
1691 * gdbinit.in: Move "break abort" to end, in case gdb complains.
1693 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
1696 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
1697 processing if add_symbol is undefined or in expr_section.

1699 constant-valued symbol, convert to O_symbol and re-reduce.
1700 (S_GET_VALUE): If symbol needs resolving, resolve it.
1701 (indent_level): No longer static.
1702 (print_symbol_value_1): Don't print frag address if it matches

1706 (print_expr_1): Fix whitespace before printing X_add_number.
1708 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1709 not symbol_new, for symbols holding expression values.
1710 * expr.h (make_expr_symbol): Move declaration here.
1711 * write.c (fix_new_exp): Handle O_add by creating an
1712 expression-valued symbol, and calling fix_new_exp recursively.
1713 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1714 undefined symbol and a constant, fold the constant into the fixup,
1715 and refer to the undefined symbol directly. Then process the
1716 fixup again from scratch.
1717 (write_object_file): Before calling adjust_reloc_syms, make a pass
1718 through the symbol list trying to resolve values.
1720 * write.c (print_fixup): New routine, for debugging.
1721 (write_relocs): Call bfd_install_relocation. Deleted various
1722 hacks for working around problems with bfd_perform_relocation.
1724 * Makefile.in (VERSION): Update to 2.4.90.
1726 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1728 * Makefile.in (gasp.o): Depends upon config.h.
1730 * config/tc-mips.c: Include subsegs.h.
1731 (md_apply_fix): If an unconditional b or bal overflows, and we are
1732 not assembling PIC code, replace it with a j or jal.
1734 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
1735 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
1737 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1739 * write.c (write_relocs): Add file name and line number to
1740 as_fatal calls. Handle bfd_reloc_overflow case specifically when
1741 RELOC_EXPANSION_POSSIBLE.
1743 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1745 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1746 here. Use them for deciding which PRINTF*LIKE macro definitions
1748 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
1749 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1750 default definitions matching what we were doing before.
1751 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1752 always use the varargs form if not using stdarg. It's safe to
1753 always use vfprintf, because libiberty will provide it if the
1754 native system doesn't. Also, always make format be const.
1755 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
1757 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

1770 (listing_newline): Check filename as well as line number when
1771 deciding whether to record it.
1772 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1773 false (if defined) as well as checking for reg_section.
1774 (listing_listing): Iterate fetching lines while line number is too
1775 low, and we haven't run off the end of the input file.
1777 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1779 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1781 * ecoff.c (ecoff_generate_asm_lineno): check if
1782 current_stabs_filename is NULL before strcmp.
1783 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
1786 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1788 * config/ho-*.h: Now-unused files deleted.
1790 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1791 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1792 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1793 zero. Don't call obj_frob_forward_symbol.
1794 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
1795 X_add_number is zero.
1796 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1798 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1800 (strchr): Don't declare.
1801 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
1802 md_estimate_size_before_relax, md_ri_to_chars,
1803 md_create_short_jump, md_create_long_jump.
1804 (brtab_emit): Use data_section, not SEG_DATA.
1806 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1808 * config/vms-conf.h: new file, manually derived from conf.in.
1809 * config-gas.com: use it, and eliminate obsolete "host.h".

1813 * config/tc-ppc.c (ppc_current_block): New static variable.
1814 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
1815 ppc_current_block. Don't move around any stab symbol, just those
1817 (ppc_bs): Set ppc_current_block.
1818 (ppc_es): Clear ppc_current_block.
1819 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1820 from the csect of the enclosing block.
1822 * config/tc-mips.c (insns_since_cache_access): Remove.
1823 (append_insn): Remove setting of insns_since_cache_access, and
1824 special 4600 handling; it turns out not to be required.
1826 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1828 * config/tc-mips.c (md_shortopts): Remove E.
1829 (md_longopts): Add EB and EL.
1830 (md_parse_option): Handle -EB and -EL as separate options, rather
1831 than as a single -E option with an argument.
1833 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
1835 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
1836 involving global symbols too.
1838 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1840 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1842 * configure.in: Test for remove, not delete. Fix cross-assembler
1844 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
1847 * read.c (pseudo_set, case O_symbol): If
1848 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1849 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1850 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
1852 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
1854 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1855 many others): new macros; values obtained from "DSTRECRDS.SDL".
1856 * config/obj-vms.h (various): use them.
1857 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1858 representation (only enum bitfields can avoid being bitstrings).
1859 (bitfield_suffix, setup_basic_type): new routines.
1860 (VMS_typedef_parse): use them. Now recognize bitfields of all
1861 integral types, not just type `int'. Caveat: the representation
1862 used for bitfields still does not work for objects placed in
1863 registers, and gcc's optimizer sometimes puts small structs there.
1865 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1867 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1868 bit from const_flag.
1869 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
1870 (tc_frob_label): define this to call vms_check_for_special_label,
1871 and declare the latter.
1872 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1874 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1875 (vms_check_for_special_label): new routine (tc_frob_label).
1876 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1877 and `gcc2_compiled.' labels; they won't reach here any more.
1878 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1879 double', use `vax_g_doubles' flag to select type of double.
1880 (VMS_write_object_file) [traceback setup]: don't pass symbols
1881 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1882 and TBT_Routine_End functions.
1884 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
1886 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1887 S_GET_VALUE() to avoid many repeated function calls.
1888 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1889 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1890 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1891 be obsolete; gcc does it automatically for vms target. It's
1892 also misnamed, because it is for the "VAX C" run-time library,
1893 not the newer "DEC C" one which has much different startup code.]
1894 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1895 `S_GET_xxx(symbol) = new_value'.
1897 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1899 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1900 not &bfd_abs_section.
1902 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1904 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1906 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1908 * expr.c (expr): Don't reduce the difference of two symbols in the
1909 same frag if the symbols are not in normal sections.
1911 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1912 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1913 (obj_attach_unwind_info): Do not define. Not needed anymore.
1914 * config/tc-hppa.c: Delete whitespace at EOL.
1915 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1916 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1917 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1918 fixups, store 32bits of unwind information in the fx_addnumber

2880 (DBG_S_C_REAL8_G, DBG_S_C_COMPLX8_G): G_float versions of
2881 REAL8 and COMPLX8; not used yet, because gcc outputs the same
2882 .stabs for `double' regardless of whether `-mg' is used.

2894 $8,%hi(foo); lw $8,%lo(foo)($8)'' work correctly.
2896 Mon Jun 13 12:08:52 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2898 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
2899 to put a common symbol in a set.

2905 OBJ_BOUT if not BFD_ASSEMBLER.
2906 * config/aout_gnu.h (N_WEAKU, N_WEAKA, N_WEAKT, N_WEAKD, N_WEAKB):
2907 Define as in ../include/aout/aout64.h.

2944 * read.c (emit_expr): Use memset to zero out memory, rather than
2945 going through md_number_to_chars. This permits handling symbolic

2998 m68040_control_regs, m68060_control_regs): New arrays.
2999 (control_regs): New pointer.
3000 (m68k_ip): Use control_regs instead of testing CPU every time.
3001 Use last_movec_reg too. In error messages, handle 68060, and
3002 print 68060 for mfloat, too.
3003 (m68k_init_after_args): Handle "68060". Use m68040up for making
3004 m68851 choice. Set control_regs.

3316 * config/tc-m68k.c (DATA, ADDR, SP, FPREG, COPNUM, BAD, BAC):
3317 Define as macros instead of enumerators, since the Apollo compiler
3318 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum
3320 (make_pcrel_absolute) [NO_PCREL_RELOCS]: New function.
3321 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
3322 R_DIR16, and R_DIR32 relocs.
3323 * config/tc-m68k.h [TE_APOLLO] (COFF_MAGIC, COFF_AOUTHDR_MAGIC):
3324 Use Apollo versions.
3325 [TE_APOLLO] (OBJ_COFF_OMIT_OPTIONAL_HEADER): Undefine. That is,
3326 do include the optional header for Apollo target.
3327 (COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
3329 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
3330 can be used within a label name.
3332 * config/tc-m68k.h (m68k_init_after_args): Declare.
3333 (tc_init_after_args): Define as m68k_init_after_args.
3334 * config/tc-m68k.c (m68k_init_after_args): New function,
3335 containing one-shot code from md_assemble. Added warning for
3336 combination of 68040 and 68851.

3351 and bfd_ecoff_set_regmasks to set the GP value and the register
3352 masks, rather than using the now obsolete fake .reginfo section.
3354 Fri Apr 22 15:17:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3356 * listing.c (list_symbol_table): Don't print register symbols as
3359 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
3360 underscores, since symbol_new will already have done it.
3361 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
3363 * as.c (main): If tc_init_after_args is defined, invoke it after
3364 all arguments have been processed.
3366 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
3367 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
3368 section instead of .text. Call create_target_segments.
3369 * read.c (demand_copy_string): No longer static.
3371 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3373 * config/tc-mips.c (append_insn): Permit branches to be switched
3374 with the preceding instruction even if .set nobopt has been seen.
3375 .set nobopt actually controls whether to bring up an instruction
3376 from the branch target, which gas does not currently support.
3378 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3380 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

3393 * config/tc-sparc.c (md_section_align): Always round up to
3394 multiple of alignment power specified in bfd target vector.
3396 * gasp.c: Include ctype.h.

3420 not reset the segment if just updating a space.
3421 (pa_spaces_begin): Set BFD section flags for all built-in
3424 Fri Apr 15 10:51:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

3427 (add_procedure): Set first_proc_ptr if it hasn't been set.
3428 (ecoff_build_lineno): If the first procedure does not start at
3429 address zero, insert a dummy line to compensate.
3431 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
3434 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3436 * expr.c (operand): Try to parse "0f" and "0b" sequences as
3437 floating point and binary numbers respectively; if it doesn't
3438 work, treat them as local labels.
3440 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
3441 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
3443 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
3445 * vmsconf.sh: In generated file, get ".obj" suffix right, build
3446 source files from other directories into objects in the current
3447 directory, and specify PSECT attributes explicitly to linker.
3448 Also added missing label.
3449 * Makefile.in (stamp-mk.com): Reference new variable
3450 VMS_OTHER_OBJS for list of non-local object files, instead of

3465 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
3466 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
3467 argument, the reloc type.
3468 (load_register): Pass reloc type to macro_build for 'u'.
3469 (macro): Likewise. For M_LA_AB permit a difference expression
3470 when generating embedded PIC code between an arbitrary symbol and
3471 a symbol in the .text section.
3472 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
3473 BFD_RELOC_PCREL_LO16 to be emitted.

3481 * subsegs.c (subsegs_begin): Call memset with args in the correct
3483 (subseg_get): Clear newly allocated seginfo, set its pointer slots
3484 to NULL instead of 0.

3488 * config/tc-hppa.c (pa_procend): Handle case where label was
3489 defined after the .proc directive.
3491 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
3492 procend for a procedure without a name.

3513 (hppa_tc_symbol): Likewise.
3515 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
3516 elf_tc_make_sections stuff. It was there to support PA braindamage
3517 which has been fixed, and in the case of elf_tc_make_sections is
3518 redundant with elf_tc_final_processing.
3520 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3522 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

3527 * config/tc-mips.c (mips_ip): For case 'o', when generating
3528 embedded PIC code, accept the difference between two local symbols
3530 (mips_force_relocation): Only force a reloc to be generated for a
3532 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
3533 value into the file if the fixup will not generate a reloc.
3535 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
3537 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
3538 don't spew remainder of input file in error message.
3539 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
3540 message with reloc type and try to process remainder of file.
3542 * doc/Makefile.in (install-info-as, install-info-gasp): New
3543 targets, now explicitly checking $(srcdir) for info files.
3544 (install-info): Depend on both of them; do nothing more.
3546 Mon Apr 4 17:06:04 1994 Jeffrey A. Law (law@cygnus.com)
3548 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
3550 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3552 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
3553 flag rather than signedp field. Only permit extended range if
3554 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
3555 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
3557 * config/tc-ppc.c (ppc_size): New static variable.
3558 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
3559 (md_begin): If an instruction has a size specific flag set, only
3560 add it if we are assembling that size.
3562 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3564 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
3565 cross section PC relative relocs right for COFF and ELF.
3567 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3569 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
3570 (OBJ_PROCESS_STAB): Don't define.
3572 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3574 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
3575 the type of symbol set symbols which happen to be in the absolute
3576 or undefined section.
3578 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
3580 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
3581 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
3582 and -many (all architectures).
3584 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3586 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
3587 involving a function symbol which is not a plabel to zero.
3588 (md_apply_fix): Never pass a function symbol to field_adjust.
3590 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3592 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
3593 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
3595 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
3596 branch with an instruction that uses $at, in case the branch is
3598 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
3599 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
3600 to make it pcrel_offset.
3601 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
3602 reloc->address; another gruesome hack to get gas reloc handling to
3605 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3607 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
3610 (emit_insn): New function.
3611 (md_assemble): Call it.
3612 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
3614 (lituse_pending): New variable. Set by anything that generates a
3615 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
3616 tested by code that might want to emit a LITUSE reloc.
3617 (emit_unaligned_io): New function. Currently calls md_assemble,
3618 but it should eventually be converted to generate the insn itself
3619 and call emit_insn directly.
3620 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
3621 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
3622 emit_bis_r): Likewise.
3623 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
3624 (alpha_ip, label get_macro): Don't emit the final instruction if
3626 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
3627 unaligned memory access macros.
3628 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
3629 the value can't be resolved.
3631 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3633 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
3634 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
3635 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
3637 (mips_force_relocation): New function.
3638 (md_apply_fix): Set fixP->fx_done appropriately.
3639 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

3647 * config/tc-mips.c (enum mips_pic_level): New enum.
3648 (mips_pic): Change from int to enum mips_pic_level. Change all
3649 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3650 (load_address): Handle EMBEDDED_PIC.
3651 (macro): Handle EMBEDDED_PIC in all PIC cases.
3652 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3653 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3654 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3655 works). Do not permit -G with SVR4_PIC.
3656 (s_abicalls): Warn if -G was used, and force -G 0.
3657 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3658 anything but a.out, not just for ELF. For ECOFF, don't generate a
3659 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3661 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3663 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3665 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3666 parameters to avoid losing when compiling with HP CC.
3667 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3669 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3671 * Makefile.in (config-stamp): If `defs' is defined, emit a
3672 preprocessor directive to create a macro named by this value into
3673 config.new; don't explicitly go for BFD_ASSEMBLER.
3674 * configure.in: Define `defs', not `BFDDEF'. Set it to
3675 MANY_SEGMENTS for any obj-coffbfd target.
3676 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3677 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3679 (LOCAL_LOADLIBES): Deleted.
3680 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3681 * config/m88kcoff.mt (TDEFINES): Ditto.
3682 * config/ebmon29k.mt: Deleted.
3683 * config/h8300hds.mt: Deleted.
3684 * config/ic960coff.mt: Deleted.
3685 * config/sparc.mt: Deleted.
3686 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3687 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3688 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3689 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.
3690 (TDEFINES): Don't define the coffbfd macros.

3693 (OBJS): Add $(TE_OBJS).
3695 * config/obj-coff.c (obj_pseudo_table): Supply "section"
3698 * write.c (set_symtab): Define only if BFD_ASSEMBLER.
3700 Sun Mar 20 12:06:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3702 * Makefile.in (STAGESTUFF): Add gasp.new.
3704 Fri Mar 18 20:09:16 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3706 * write.c (symbol_table_frozen): New variable, to be set after
3707 bfd_set_symtab is called.
3708 (dump_section_relocs): Note whether a symbol is a section symbol
3710 (adjust_reloc_syms): For now, always supply an absolute symbol for
3711 fixups without symbols but not yet `done'. Use section_symbol to
3712 get the symbol, instead of going directly for abs_symbol.
3713 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3714 reloc is not a section symbol and is not in the symbol table.
3715 (set_symtab): New function, broken out from write_object_file.
3716 Counts symbol table instead of relying on an earlier count.
3717 (write_object_file): Call set_symtab, but do it after potentially
3718 invoking the *_frob_file macros. Don't bother counting symbols.
3719 Call symbol_remove, instead of expanding it in place. Moved the
3720 conditionalized `object_file_size' declaration down to
3721 conditionalized block where it's used. When using the absolute
3722 symbol for a fixup without a symbol, set sy_used_in_reloc.
3723 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3724 the correct symbol for the absolute section.
3726 * subsegs.c (section_symbol): Use symbol_new instead of
3727 symbol_make, since we may want it to go into the symbol table.
3728 Make the new symbol have internal linkage. If
3729 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3730 symbol with the newly created GAS symbol.
3731 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3732 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
3734 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
3736 * config/tc-sparc.c: Include subsegs.h.
3737 (in_signed_range): New function.
3739 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3740 (sparc_ip, label "immediate"): Reject constants for pcrel
3741 instructions only if the relocation type indicates a "call"
3742 instruction and the offset is within range of a "jmpl %g0". If
3743 it's not in range, use the absolute section symbol plus an offset.
3744 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3746 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3748 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3751 * configure.in: Eliminated all targets using obj-coff but not
3752 defining BFD_ASSEMBLER; I think all such targets that are
3753 supported will be matched by real CPU-OS combinations earlier in
3755 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made

5604 BFD_RELOC_MIPS_GPREL. Added new case a.
5605 (set_at, load_register, macro): Changed calls to macro_build to
5606 pass new argument for i, j and o cases.
5607 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

5828 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
5829 the table, require that the one without bit 0x1000000 set come

5888 * write.c (write_relocs): For relocs that are pc_relative and
5889 pcrel_offset and not partial_inplace, adjust reloc->addend to

5940 OPTIONAL_REGISTER_PREFIX if either is already defined.
5942 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
5944 * configure.in: Set bfd_gas for all sparc targets. Added facility
5945 for keeping or rejecting configurations still under development;
5946 default is to assume production environment, and reject configs
5947 still being worked on. Mark Elf configurations (except sparc and
5948 i386) as developmental. Deleted cases matching some generic names
5949 in favor of more specific names. (E.g., when we get Alpha

5966 through inclusion of tc-hppa.h. Delete all forward declarations
5967 for functions only used within tc-hppa.c, likewise for structures,
5968 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
5969 conditional code in a few small places.
5971 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
5972 structures, global variables, forward declarations together.

5974 conditional code -- try to group conditional code together
5975 into a few places. Make all functions and variables which
5976 are only used within tc-hppa.c static. PARAMize all functions.
5977 Add comments to functions. Delete unused functions, variables,
5978 #defines, etc. Delete unused members within structures. Delete
5979 ldil;ble hacks -- it is believed they were installed to work
5980 around old gas bugs. Avoid using mixed case for local
5981 functions, variables, and structures. Fix formatting problems
5982 not found by GNU-indent. Add FIXME notices for things which
5983 should be worked on the near future. Delete lots of old
5984 useless (1.36 PA-SOM) code.
5986 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
5987 field of the fixS structure. Needed to build unwind
5988 descriptors correctly.

6013 a multiple of the section alignment rather than always a
6016 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
6017 bits are zero (eg they specify no relocations), then do not even
6018 bother adding their entries to thesymextn section.

6062 of text, data and bss sections to 4.
6063 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
6065 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
6066 ELF, since the ELF object format does not have these type of
6067 relocations. Change the abort into as as_bad and return
6068 BFD_RELOC_NONE to silence compiler warnings.
6069 (md_assemble): Keep track of the instruction size. Allow white
6070 space between the $ and the constant for compatibility with older
6071 gases and other assemblers.

7081 are also magic, and have special default flag settings.
7082 (obj_elf_frob_symbol): Since the return value from this function

7146 * Extensive changes to permit symbols to contain any expression
7147 type and to delay the computation of the expression until the
7148 value is actually needed. This permits setting symbols to values
7149 calculated based on object code size. Expressions were changed to
7150 no longer be in a section, to stop the overloading of segment and
7151 expression type that previously occurred.
7153 * as.c (big_section, pass1_section, diff_section, absent_section):
7155 (expr_section): Added (used for dummy symbols which hold

7355 sy_resolved and sy_resolving single bit fields.
7356 * symbols.c (symbol_new): Don't initialize sy_forward field.

8418 references don't appear to work right.
8420 * as.h (const, volatile): Put these definitions back, and use
8423 * doc/as.texinfo: First pass at using new texinfo features --
8424 variables, conditional tests. Far from complete.

8450 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
8451 the bottom (make expands variables in dependencies when the
8452 dependencies are read, not when they are used).
8454 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
8455 a29k .bss section; the mondfe program doesn't like it.

8476 source directory, if that's not the current directory.
8478 * configure.in (per-host): Accept MIPS host with BSD version

8500 process relocs if there aren't any relocs to process. Avoids
8501 malloc/free bug on SCO too.

8504 avoid some redefinition complaints on some systems.
8505 (const, volatile): Don't need these conditionally defined if we
8506 use CONST and VOLATILE from ansidecl.h.
8507 (seg_name): Use CONST, not const.
8509 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
8511 * config/tc-mips.c: Reindented to GNU standards.
8513 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
8515 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
8516 (fixup_segment): Add a29k special case; the linker is not prepared
8517 to see a segment offset here.
8519 * app.c (do_scrub_next_char): Added new state, 10, modifying state

8522 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
8524 * Makefile.in: add dvi target; as-$(config).texinfo might live in
8525 srcdir, might be in objdir.

8545 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
8546 bignums, but don't emit error message.
8548 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
8550 * Makefile.in (targ-cpu.o): Depend on config.h.
8552 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
8554 * app.c (do_scrub_next_char): Added new state, 9, to avoid
8555 dropping a space immediately following an identifier.
8556 * expr.c, write.c: Rewrote assert expressions to not use multiple
8557 lines; I don't think that can be done portably.
8558 * config/tc-mips.c (macro): Use $AT if target register is zero in
8559 load instruction, which it can be for a floating point load.
8561 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

8572 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
8573 z8k-opc.h, not z8k.h.
8575 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
8578 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8580 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
8582 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
8584 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

8633 prototypes for all static functions. Moved existing minimal
8634 debugging format support info #ifndef OBJ_ECOFF blocks.
8635 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
8636 does not support a non sign extended high 16 bits reloc. Adjusted
8637 all callers accordingly.
8638 (tc_get_register): Renamed from get_register, and made non-static.

8683 * make-gas.com: Find obstack.obj if it's not in the current
8685 * read.c (s_ignore): Don't declare is_end_of_line. It's
8686 redundant, and triggers a VMS gcc compiler bug.
8688 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
8689 current segment as an argument. (Ignored in all cases but VMS.)
8690 All callers and definitions changed.

8709 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
8710 Call elf_xstabs for .stabs and .xstabs operators.
8712 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
8714 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
8717 * configure.in: mips-bsd configuration was missing format spec.
8720 * Makefile.in (Makefile): Depends on configure.in.
8722 * config/tc-mips.c (append_insn): Don't check for alignment of
8723 frag in memory; alignment of instructions in section is a separate

8743 * config/tc-sparc.c (s_xword): Now call big_cons, so large
8744 constants are accepted, but symbolic values are not. GCC will not
8745 generate the latter currently.
8747 * frags.c (frag_init): New function.
8748 (zero_address_frag, bss_address_frag): Now initialized at run
8750 * as.c (main): Call frag_init.

8794 (fixup_segment): Make sure common-section symbols get treated the
8795 same as undefined symbols.
8796 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type

8826 new section/subsection.
8828 * read.c: Don't include ctype.h.
8829 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
8830 for now; should be machine-dependent.
8832 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
8833 targets, forcing BFD use.

8855 (write_object_file) [! BFD_ASSEMBLER]: Call it.
8856 (relax_and_size_seg) [BFD_ASSEMBLER]: New function; relax section
8857 and set its size and flags.
8859 * struc-symbol.h (struct symbol) [BFD_ASSEMBLER]: Replace some

9002 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
9003 latter, instead of selecting with preprocessor conditionals.
9005 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9007 * configure.in: recognise all sparclite variants

9017 * expr.c (operand): If character other than comma or newline is a
9018 logical end-of-line character, use the newline case.
9019 From Eric Youngdale:
9020 (operand): Set X_add_number field for floating-point numbers.
9021 (operand): Treat zero byte as end-of-operand.
9023 * configure.in (per-target): Look for with_bfd_assembler option.
9024 For now, only accept "no", until the merge is done.
9026 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
9027 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
9028 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
9029 * read.c: Finish conversion to S_* macros in the VMS only
9030 parts of the program. Add "const" modifier to hex_value.

9033 * expr.c: Add "const" modifier to hex_value.
9034 * symbols.c: Finish conversion to S_* macros in the VMS only
9035 parts of the program. Add "const" modifier to
9036 md_[long,short]_jump_size. Remove declaration of const_flag
9037 (which will be declared in obj-vms.h).
9038 * write.c: Add "const" modifier to md_[long,short]_jump_size.
9039 Fix arguments to VMS_write_object_file.
9040 * config-gas.com: New file. Script for VMS systems to set up the
9041 configuration to build gas for VMS, and create config.status.
9042 * make-gas.com: Redone to work with new scheme.
9043 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
9045 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
9046 will swap bytes if needed on a big endian system. Use throughout
9048 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
9049 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
9050 types of malformed stabs. Change parsing algorithm so that we are
9051 more certain of having all of the information that we need on hand.
9052 * obj-vms.c (final_forward_reference): New function, used to help
9053 resolve the data types of as many struct elements as possible
9054 when some part of the struct is not fully defined by the compiler.

9057 * obj-vms.c (VMS_write_object_file): Define all vtable psects
9058 as symbols as well in the object file. Look for external functions

9060 g++ compiler is incapable of doing this.
9061 * tc-vax.c: Add '1' option for backward compatibility with older GCC
9063 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
9064 * input-scrub.c (as_where): Fix bug where as would crash if we did not
9065 have the name of the source file yet.
9066 * config/ho-vms.h: define HO_VMS, not HO_VAX.
9068 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
9070 * read.c (s_data): Always use "data_section", since it'll map to
9071 SEG_DATA or SEG_E1 if needed.
9072 (s_lcomm): Likewise with bss_section.
9073 (s_fill): Use memset, not bzero.
9075 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

9097 (big_section, reg_section, pass1_section, diff_section,
9098 absent_section, text_section, data_section, bss_section): If
9099 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
9100 mapping to segT enum values.
9101 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
9102 if these are used or defined, if BFD_ASSEMBLER.
9103 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
9104 subseg_new split into two functions.
9105 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
9107 * as.h (volatile): Don't define if already defined.
9108 (had_errors, had_warnings): Provide prototypes for ANSI C even if
9110 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
9111 declare with format attribute for -Wformat checking.
9113 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
9115 * app.c, config/tc-*.c: Don't include read.h, since it is already
9118 * These are based on patches from Minh Tran-le
9119 <mtranle@paris.intellicorp.com>.
9120 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
9121 obj_format coffbfd and gas_target i386coff for target.
9122 (i[34]86-*-isc*): New host (uses sysv).
9123 * config/i386aix.mt: Removed (no longer used).
9124 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
9126 (LDFLAGS): Added, defined as -shlib.
9127 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
9128 * config/te-sco386.h (LOCAL_LABEL): Don't define.
9129 (DOT_LABEL_PREFIX): Define.
9130 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
9131 name rather than L0\001.

9143 (size_section): Restored sanity check.
9144 (do_relocs_for): Base section address on s_paddr rather than
9145 computing it. Adjust a29k R_IHIHALF special case to account for
9146 section paddr (used to require paddr to be zero). If there are no
9147 reclos, set s_relptr to 0. Set relocation size in object_headers.
9148 (fill_section): Always set s_vaddr here, removing
9149 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
9150 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
9151 Set STYP_INFO for .comment.

9155 H_{SET,GET}_* macros.
9156 (do_linenos_for): Set lineno size in object_headers.
9157 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
9158 set s_vaddr here. If string_byte_count remains 4, set it back to
9159 0, and only write strings out if there are some. Call
9160 fill_section before do_relocs_for and do_linenos_for.
9161 (obj_coff_section): Handle optional quoted second argument giving
9162 section characteristics.
9163 (obj_coff_bss): Added to handle .bss.
9164 (obj_coff_ident): Added to handle .ident (puts string in .comment

9184 (do_scrub_next_char): For \", return " not '.
9185 (symbol_chars): Now const.
9187 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
9188 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
9190 * config/obj-coff.h: Don't use #elif.
9192 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
9193 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
9195 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
9197 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

9219 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
9220 using ZERO_BASED_SEGMENTS.
9221 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
9222 never set segment address for SEG_E2 (.bss) and don't write out
9223 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
9224 (obj_coff_endef): Don't merge labels or symbols awaiting forward
9225 definitions, and don't merge tags with non-tags. Check for .bf
9226 rather than just checking whether the second character is b and
9227 the third character is f.
9228 (obj_coff_val): gcc can generate values which we don't handle
9229 correctly; discard information for now, since it only affects the
9230 debugging information.
9231 (tag_find_or_name): Don't insert tags in the symbol table.
9232 (yank_symbols): Don't merge labels.
9233 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

9371 * all files: Whitespace changes for GNU indentation style, done by
9372 GNU `indent'. Some cleanup still needed, especially of comments.
9374 * configure.in: No te-386bsd.h file exists; don't try to use it.
9376 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
9378 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
9379 could be doing emulation.
9381 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9384 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

9398 * tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
9399 still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
9401 (insert_reg): put REGISTER_PREFIX before register names before
9402 putting them in the symbol table.
9403 * tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not

9409 * atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
9410 comment_chars, line_comment_chars and line_seperator_chars
9411 consistently const, and always initialized them. Included read.h.
9413 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
9415 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
9416 constant will not fit in an immediate field.
9417 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
9419 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
9421 * obj-coff.c (callj_table): Delete global variable.
9422 (obj_emit_relocations): Define it locally here, and only if

9428 * obj-coff.c: Replaced ANSI and non-ANSI function declarations
9429 with a single set using PARAMS macro.
9431 * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length

9436 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
9437 so widening works consistently.
9439 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
9441 * version.c: Put conditional "const" before version_string, not
9442 before dummy function for VMS. Now version 1.91.03.
9444 * app.c (do_scrub_next_char): Need double-\ before `000' to show
9445 printed rep of null character.
9447 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
9449 * obj-coffbfd.c (write_object_file): check return value of
9452 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
9454 * Support for i386-sysv.
9455 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
9456 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
9457 be used to set them all to zero as was done before.
9458 (fill_section): segment addresses now set in write_object_file.
9459 (fill_section): Don't set STYP_NOLOAD for .bss section.
9460 (fixup_segment): 386 uses strange common symbol format.
9461 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
9462 compatibility with SVR3.2 linker.
9463 * configure.in: i386-sysv and i386-sco use coffbfd.
9465 * app.c (do_scrub_next_char): discard whitespace after a label.
9467 Sat Oct 10 12:33:45 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

9474 fix i960+non-bfd coff bit rot.
9475 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
9476 support for C source listings. (obj_coff_endef): look in the right
9477 part of the symbol for the symbol name
9479 * tc-m68k.c (get_num): make it work for all segments, not just the
9482 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
9484 * configure.in: recognize i386-*-bsd emulation.

9493 * tc-z8k.c: lots of bug fixes
9495 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
9497 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
9498 #elif, since it is not supported by old compilers.
9499 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
9500 couple of expressions in tc-m68k.c.
9502 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9504 * read.c (cons): If NO_RELOC is defined, use it.
9506 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
9508 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
9510 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
9511 local labels to start with a .) and set REGISTER_PREFIX to %.
9512 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
9514 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

9525 * listing.c (debugging_pseudo): Add stabs and stabn as things to
9528 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
9530 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
9531 sections starting from zero, rather than making them consecutive.
9532 This makes subsequent reloc calculations easier, esp if the object
9533 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
9534 allocate lcomm in .data rather than in .bss. It seems that some
9535 tools can't cope with a non-zero sized bss before linkage.
9537 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9539 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
9540 throughout. That enum no longer means what we thought it meant.

9543 "-mno-688[58]1" options.
9545 * tc-m68k.c: Added CPU32 support.

9553 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
9554 Change LIBDEPS dependence to LIBS.
9556 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
9558 * Makefile.in (install): if $(tooldir) exists, install as in
9561 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
9563 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
9564 .word is < -32768 or > 32767. The -J flag causes the error to be
9565 ignored. This is to catch over-sized switches generated by gcc on
9566 systems which don't support the broken .word hack.
9567 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
9568 write.c (fixup_segment): check for signed .word overflow if
9569 WARN_SIGNED_OVERFLOW_WORD.
9571 * write.c (fixup_segment): fixed missing parens in expression
9572 checking for byte or word overflow.
9574 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
9575 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
9576 WARN_SIGNED_OVERFLOW_WORD.
9578 * obj-coffbfd.c (fixup_segment): fixed missing parens in
9579 expression checking for byte or word overflow.
9581 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)

9584 * obj-coffbfd.h : added stuff
9585 * tc-i386.c (tc_coff_fix2rtype): new function
9586 * tc-i386.h : new coff defines
9588 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
9590 * input-scrub.c (input_scrub_push): call input_file_begin, not
9592 messages.c (as_perror): print ": " between the passed in error and
9593 the strerror, like perror does.
9595 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
9597 * Makefile.in: use gas_target instead of modifying target_cpu.
9598 From Steve Chamberlain:
9599 Makefile.in: Handle m68*-*-coff*.
9600 read.c, read.h: add mult argument to s_space
9602 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
9603 Motorola and MIT syntax; gas can now assemble either type of
9605 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
9606 From Steve Chamberlain:
9607 m68kcoff.mt: for m68k COFF.
9608 obj-coffbfd.c: (fixup_mdeps) added
9609 (size_section) removed bad sanity check
9610 (fill_section) added rs_machine_dependent case
9611 (write_object_file) call fixup_mdeps
9612 (fixup_segment) set fx_subsy to 0.
9613 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
9615 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
9618 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9620 * Makefile.in (LIBS): Include opcode library.
9622 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
9624 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers

9642 tc-i960.c (md_ri_to_chars): Always output bout object file in
9643 little endian byte order (used to use endianness of host).
9645 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9647 * config/tc-m68k.c (init_table): Now const. Always include 68851
9648 data, so that "bc" is available to 68040 cache instructions.
9649 Added "tt0", "tt1", and 68ec030 variants.
9650 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9651 (enum _register): Added TT0, TT1.
9652 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9653 line number correctly in "internal error" messages. Don't print
9654 architecture-mismatch message for operand errors.
9656 From Colin Smith (colin@wrs.com):
9657 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
9658 than install_operand.

9662 * listing.c (buffer_line): rewind to the start of include
9663 files, they might be included twice.

9670 one element of a family.
9672 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
9674 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
9675 so that we can assemble hand-written libgcc code.
9677 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9679 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9680 has already been formatted (but may still contain %-characters).
9683 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
9685 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
9686 written with indirection on the last two operands, which can be
9687 either data or address registers. Added a new operand type 'r'
9688 which accepts either register type. Added '(' to notend stuff in
9689 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
9691 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

9703 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
9704 defined, call it. Change segments before calling fixup_segment.
9705 (relax_align): If linkrelax, provide extra padding.
9707 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
9708 their not having symbols associated.
9710 * tc-i960.c (norelax, instrument_branches): Default initializer is
9712 (linkrelax): Delete variable definition.

9735 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
9736 being used with args swapped, causing occasional lossage when
9737 refilling buffers after an include file.
9739 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
9741 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
9742 version. Discard bogus DONTDEF version.
9743 (as_warn, as_bad, as_fatal): Likewise.
9745 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
9747 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
9748 selected architecture, print a message saying so and listing what

9770 * read.c (s_fill): make the .fill size clamped error a warn and
9771 fix bug where 0's were always placed.
9773 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
9774 two bytes of any constant with 0xff:

9778 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
9779 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.

9793 * configure.in (mips host): Accept "ultrix" with version number.
9795 * expr.c (floating_constant): Separate "=-" to avoid confusing
9796 ancient or broken compilers.
9798 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
9799 processor/opcode mismatch, so reword the error message.
9800 (md_assemble): If no CPU has been set (even if FPU/PMMU
9801 characteristics have been), default to 68020. Don't need extra
9802 quotes around error string.
9804 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
9806 * read.c (potable): Revert sac's incorrect change made Jul 13.

9876 * write.c (write_object_file): If a.out don't use the old way for
9878 * config/obj-a.out (s_sect): complain if the user tries to use a
9879 subsegment with a value which might interfere with out -R hackery.
9880 * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
9881 rather than use ugly if tree. (init_regtable): insert register

9884 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
9886 * write.c (write_object_file): keep the fix_tail clean, which
9887 fixes a bug in -R where relocations were being lost.
9889 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
9891 * configure.in: recognize m680x0 as having sun3 emulation mode for

9917 calc the base of relocs correctly.
9918 * tc-a29k.c (parse_operand): allow expressions to be in any section.
9920 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
9922 * as.c, write.c: use -K rather than -k for the broken word warning

9938 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
9940 * Makefile.in (install): Install into $(tooldir)/bin, since that's
9941 where gcc looks for it.
9943 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
9945 * Makefile.in: Changed some lines to be less confusing for some
9948 * input-file.c: Conditionalize on _IOFBF, not VMS.
9950 * read.c, write.c: Change a series of ifdef/elif to

9980 local_labels_fb must be < 10.
9982 * symbols.c: remove local_labels_dollar, replace with a function

10011 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
10013 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
10015 * expr.c (operand): if can't work out what sort of operand it is,
10016 then look through FLT_CHARS for a hint.
10018 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
10020 * Makefile.in, configure.in: removed traces of namesubdir,
10021 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10022 copyrights to '92, changed some from Cygnus to FSF.
10024 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
10025 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10026 copyrights to '92, changed some from Cygnus to FSF.
10028 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10030 * expr.c: If an expression is single comma, then return with
10031 SEG_ABSENT rather than an error - since the sparc front end does
10032 really strange things with things like fbge,a
10034 * as.h: include bfd.h if using many sections
10035 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
10036 local labels didn't work.
10037 * listing.c (list_symbol_table): don't core dump when there's no
10039 * write.c, write.h: call fix_new with the right number of args on
10041 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
10044 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10046 * app.c: MRI compatibility - allow single quote to start a string.
10047 * as.c: fix typo recently introduced.
10048 * as.h : Don't include aout/reloc.h - it's not right for COFF!
10049 * expr.c: Much rewriting, to accomodate MRI syntax for
10050 expressions. Also easier to read now.
10051 * listing.c: Put back defuns
10052 * read.c: modified to accept MRI syntax, put back listing pseudo
10053 ops so that an assembler built with NO_LISTING ignores list ops
10055 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
10056 machine is a SPARC or a 29K.
10057 * config/obj-aout.c: added s_sect pseudo op
10058 * config/obj-coffbfd.c: lints, set the filehdr flags right and
10059 fill in the timestamp.
10060 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
10061 anymore, define all the relocs which the tc-<x> bit will use so we
10062 can translate from them to the coff types.
10063 * config/tc-a29k.c: reloc_type isn't ane enum any more
10064 * config/tc-m68k.c: Added NO_RELOC definition.
10066 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10068 * Makefile.in: put header files before C source for TAGS; remove
10069 references to non-existent syscalls.h.
10071 * read.c, write.c subsegs.c: back out the .bss changes.
10073 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
10075 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
10077 * a.out.h: removed.
10079 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
10081 * symbols.c (local_label_name): symbols now start with ^A.
10083 * read.c, subsegs.c, write.c obj-coff.c: added handling of
10084 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
10085 generate these sections. .align: will use NOP_OPCODE or 0
10086 for padding. This is just for being nice to the
10089 * expr.c (operand): changed to generate local label "\001L0"
10090 starting with a ^A so that it is recognized as a local label.
10092 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
10094 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
10095 i/o opcodes - inb, inw, outb and outw. string manipulation with
10096 att syntax - scmp, slod, smov, ssca, ssto.
10098 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
10099 to just after .file .
10101 In obj_crawl_symbol_chain() where it tries to put the external
10102 symbols apart, with the condition:
10103 (!S_IS_DEFINED(symbolP) &&
10104 !S_IS_DEBUG(symbolP) &&
10105 !SF_GET_STATICS(symbolP))
10106 it was moving too many symbols out. So I switch it back to the
10108 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
10110 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
10111 so that we don't use the F_RELFLG which make the linker complain
10112 that somebody has stripped the relocation info.
10114 Also, the AIX ld program require that the relocation table
10115 is sorted by r_vaddr like the standard ATT assembler does.
10117 [he also changed the sizeof(struct ...)'s into the coff
10118 style FOOSZ macros. I'm not sure this is right, but I can't
10119 remember why. xoxorich.]
10121 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
10123 * Makefile.in, configure.in, doc: use the doc. Build it, install
10126 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
10128 * read.c: white space and comments only.
10130 * configure.in: use the new atof-ns32.c for ns32k.
10132 * write.c: comment change only.
10134 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
10135 aren't yet integrated.
10137 * tc-i860.[hc]: blew off the dust. Something must still be done
10138 about conflicting relocation types.
10140 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
10143 * tc-i960.c, tc-sparc.c: white space and comments only.
10145 * tc-a29k.h: delete duplicate macro definition.
10147 * new file atof-ns32k.c copied from hack's last unreleased gas.
10149 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
10151 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
10154 * nearly everything. flush ChangeLog, package as gas-1.92.1.
10155 ChangeLog's prior to this are sketchy at best. I have logs.
10156 They just aren't ChangeLogs.
