1478 * config/tc-hppa.c: Eliminate all uses of fx_addnumber.
1479 (tc_gen_reloc): Simplify. It's no longer necessary to set a
1480 reloc's addend field to zero for function symbols.
1481 (md_apply_fix): Simplify. For fixups which will require a SOM
1482 reloc, just clear out the necessary bits in the output file.
1484 Fri Oct 14 19:06:46 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1486 * Makefile.in (BISON): Use bison -y, not bison.

1500 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
1502 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
1503 it's better to use the one in libiberty.
1505 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1507 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
1508 change; it breaks the rs6000 support, and doesn't seem to be
1511 Wed Oct 12 11:56:50 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
1513 * config/tc-i386.h,te-netbsd532.h (TARGET_FORMAT): Changed to

1519 rather than explicitly adding the frag address.
1520 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark
1521 the end of the line numbers; this replaces the zero entry which
1522 used to be added by coff_add_linesym, removed Oct 7.
1523 (coff_adjust_section_syms): Ignore sections with no seginfo.
1525 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1527 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a
1528 "stage" symlink to the appropriate stage* directory, and use it
1529 instead in the -B options.
1530 (comparison): Revert yesterday's change.
1532 Tue Oct 11 16:48:11 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1534 * config/tc-sparc.c (tc_gen_reloc): For non-a.out relocations, if
1535 pc-relative, use fx_offset only, ignore address of relocation.
1537 Tue Oct 11 15:24:00 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
1539 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
1540 for an embedded PIC switch expression, since the definition of
1541 S_IS_LOCAL was changed.
1543 Tue Oct 11 15:05:11 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
1545 * Makefile.in (comparison): When comparing as.new or gasp.new, try
1546 running the binary through sed to avoid differences due to
1547 "stage1" or "stage2" having been written into the binary.
1549 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
1551 ELF symbol size handling, based on code from Eric Youngdale:
1552 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an
1553 expression pointer to the symbol structure, used for `size'
1554 expressions that couldn't be reduced to constants when initially
1556 (elf_frob_symbol): Declare.

1559 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
1561 (obj_elf_size): Deleted unused code. If size is non-reducible
1562 expression, allocate some storage for the sy_obj field and copy
1564 (elf_frob_symbol): New function. Computes sizes, calls
1565 ecoff_frob_symbol if appropriate.
1567 * write.c (fixup_segment): For i386 elf and coff (for now), don't
1568 add in value of symbol from another defined section of the file.
1570 Fri Oct 7 17:54:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

1614 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
1616 (diststuff): New target; builds DISTSTUFF.
1617 (realclean): Separate target, depend on clean and distclean, then
1619 * make-gas.com: Deleted.
1621 * config/tc-i386.c (i386_validate_fix) [BFD_ASSEMBLER]: New
1622 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
1624 (i386_operand): Don't look up section symbol for
1626 (reloc): Always permit return of 8- and 16-bit relocation types.
1627 Add a space after "pc-relative" in the error message.
1628 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
1629 BFD_RELOC_386_GOTOFF relocs.

1633 (TC_VALIDATE_FIX): New macro -- call it.
1634 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.

1639 * write.h (struct fix): Added new bitfield fx_plt, for fixups
1640 referring to PLT entries.
1641 * write.c (fix_new_internal): Initialize fx_plt to zero.
1642 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
1643 Don't adjust fx_offset by frag address, since S_GET_VALUE now
1644 includes the frag address.
1645 (fixup_segment): Changed local var PCREL to type int, added PLT.
1646 If PC-relative fixup refers to a PLT entry for a symbol in the
1647 current section, don't reduce it.

1653 and after processing.
1654 (print_fixup): Added prototype. Show address on first line. Show
1655 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if

1669 Show fx_r_type and fx_addsy fields.
1671 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1673 * configure.in: Set bfd_gas for all sparc targets in one place,
1674 instead of separately for each. Correctly handle user-supplied
1675 "--enable-bfd-gas" option.
1677 * gdbinit.in: Move "break abort" to end, in case gdb complains.
1679 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
1682 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
1683 processing if add_symbol is undefined or in expr_section.
1684 (resolve_symbol_value, case O_add): For symbol plus
1685 constant-valued symbol, convert to O_symbol and re-reduce.
1686 (S_GET_VALUE): If symbol needs resolving, resolve it.
1687 (indent_level): No longer static.
1688 (print_symbol_value_1): Don't print frag address if it matches
1689 zero_address_frag. Don't print "resolving" if already resolved.

1692 (print_expr_1): Fix whitespace before printing X_add_number.
1694 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1695 not symbol_new, for symbols holding expression values.
1696 * expr.h (make_expr_symbol): Move declaration here.
1697 * write.c (fix_new_exp): Handle O_add by creating an
1698 expression-valued symbol, and calling fix_new_exp recursively.
1699 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1700 undefined symbol and a constant, fold the constant into the fixup,
1701 and refer to the undefined symbol directly. Then process the
1702 fixup again from scratch.
1703 (write_object_file): Before calling adjust_reloc_syms, make a pass
1704 through the symbol list trying to resolve values.
1706 * write.c (print_fixup): New routine, for debugging.
1707 (write_relocs): Call bfd_install_relocation. Deleted various
1708 hacks for working around problems with bfd_perform_relocation.
1710 * Makefile.in (VERSION): Update to 2.4.90.
1712 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1714 * Makefile.in (gasp.o): Depends upon config.h.
1716 * config/tc-mips.c: Include subsegs.h.
1717 (md_apply_fix): If an unconditional b or bal overflows, and we are
1718 not assembling PIC code, replace it with a j or jal.
1720 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
1721 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
1723 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1725 * write.c (write_relocs): Add file name and line number to
1726 as_fatal calls. Handle bfd_reloc_overflow case specifically when
1727 RELOC_EXPANSION_POSSIBLE.
1729 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1731 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1732 here. Use them for deciding which PRINTF*LIKE macro definitions
1734 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
1735 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1736 default definitions matching what we were doing before.
1737 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1738 always use the varargs form if not using stdarg. It's safe to
1739 always use vfprintf, because libiberty will provide it if the
1740 native system doesn't. Also, always make format be const.
1741 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
1743 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

1756 (listing_newline): Check filename as well as line number when
1757 deciding whether to record it.
1758 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1759 false (if defined) as well as checking for reg_section.
1760 (listing_listing): Iterate fetching lines while line number is too
1761 low, and we haven't run off the end of the input file.
1763 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1765 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1767 * ecoff.c (ecoff_generate_asm_lineno): check if
1768 current_stabs_filename is NULL before strcmp.
1769 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
1772 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1774 * config/ho-*.h: Now-unused files deleted.
1776 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1777 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1778 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1779 zero. Don't call obj_frob_forward_symbol.
1780 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
1781 X_add_number is zero.
1782 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1784 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1786 (strchr): Don't declare.
1787 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
1788 md_estimate_size_before_relax, md_ri_to_chars,
1789 md_create_short_jump, md_create_long_jump.
1790 (brtab_emit): Use data_section, not SEG_DATA.
1792 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1794 * config/vms-conf.h: new file, manually derived from conf.in.
1795 * config-gas.com: use it, and eliminate obsolete "host.h".
1797 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1799 * config/tc-ppc.c (ppc_current_block): New static variable.
1800 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
1801 ppc_current_block. Don't move around any stab symbol, just those
1803 (ppc_bs): Set ppc_current_block.
1804 (ppc_es): Clear ppc_current_block.
1805 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1806 from the csect of the enclosing block.
1808 * config/tc-mips.c (insns_since_cache_access): Remove.
1809 (append_insn): Remove setting of insns_since_cache_access, and
1810 special 4600 handling; it turns out not to be required.
1812 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1814 * config/tc-mips.c (md_shortopts): Remove E.
1815 (md_longopts): Add EB and EL.
1816 (md_parse_option): Handle -EB and -EL as separate options, rather
1817 than as a single -E option with an argument.
1819 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
1821 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
1822 involving global symbols too.
1824 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1826 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1828 * configure.in: Test for remove, not delete. Fix cross-assembler
1830 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
1833 * read.c (pseudo_set, case O_symbol): If
1834 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1835 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1836 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
1838 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
1840 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1841 many others): new macros; values obtained from "DSTRECRDS.SDL".
1842 * config/obj-vms.h (various): use them.
1843 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1844 representation (only enum bitfields can avoid being bitstrings).
1845 (bitfield_suffix, setup_basic_type): new routines.
1846 (VMS_typedef_parse): use them. Now recognize bitfields of all
1847 integral types, not just type `int'. Caveat: the representation
1848 used for bitfields still does not work for objects placed in
1849 registers, and gcc's optimizer sometimes puts small structs there.
1851 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1853 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1854 bit from const_flag.
1855 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
1856 (tc_frob_label): define this to call vms_check_for_special_label,
1857 and declare the latter.
1858 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1860 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1861 (vms_check_for_special_label): new routine (tc_frob_label).
1862 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1863 and `gcc2_compiled.' labels; they won't reach here any more.
1864 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1865 double', use `vax_g_doubles' flag to select type of double.
1866 (VMS_write_object_file) [traceback setup]: don't pass symbols
1867 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1868 and TBT_Routine_End functions.
1870 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
1872 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1873 S_GET_VALUE() to avoid many repeated function calls.
1874 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1875 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1876 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1877 be obsolete; gcc does it automatically for vms target. It's
1878 also misnamed, because it is for the "VAX C" run-time library,
1879 not the newer "DEC C" one which has much different startup code.]
1880 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1881 `S_GET_xxx(symbol) = new_value'.
1883 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1885 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1886 not &bfd_abs_section.
1888 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1890 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1892 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1894 * expr.c (expr): Don't reduce the difference of two symbols in the
1895 same frag if the symbols are not in normal sections.
1897 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1898 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1899 (obj_attach_unwind_info): Do not define. Not needed anymore.
1900 * config/tc-hppa.c: Delete whitespace at EOL.
1901 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1902 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1903 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1904 fixups, store 32bits of unwind information in the fx_addnumber
1906 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
1907 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
1908 pointer to 32 bits of unwind info.
1909 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
1910 pointer to the dummy symbol; set the addend field to fx_addnumber.

2866 (DBG_S_C_REAL8_G, DBG_S_C_COMPLX8_G): G_float versions of
2867 REAL8 and COMPLX8; not used yet, because gcc outputs the same
2868 .stabs for `double' regardless of whether `-mg' is used.
2869 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
2870 for gcc2's predefined types "complex float", "complex double",

2880 $8,%hi(foo); lw $8,%lo(foo)($8)'' work correctly.
2882 Mon Jun 13 12:08:52 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2884 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
2885 to put a common symbol in a set.

2891 OBJ_BOUT if not BFD_ASSEMBLER.
2892 * config/aout_gnu.h (N_WEAKU, N_WEAKA, N_WEAKT, N_WEAKD, N_WEAKB):
2893 Define as in ../include/aout/aout64.h.

2909 Wed Jun 8 06:28:37 1994 Bill Cox (bill@cygnus.com)
2911 * Makefile.in (check): Delete as.new dependency, so that

2928 Fri Jun 3 23:35:36 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2930 * read.c (emit_expr): Use memset to zero out memory, rather than
2931 going through md_number_to_chars. This permits handling symbolic
2932 arguments when the size is larger than sizeof (valueT), if

2984 m68040_control_regs, m68060_control_regs): New arrays.
2985 (control_regs): New pointer.
2986 (m68k_ip): Use control_regs instead of testing CPU every time.
2987 Use last_movec_reg too. In error messages, handle 68060, and
2988 print 68060 for mfloat, too.
2989 (m68k_init_after_args): Handle "68060". Use m68040up for making
2990 m68851 choice. Set control_regs.

3067 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
3068 of 0, because the latter indicates success rather than failure

3315 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
3316 can be used within a label name.
3318 * config/tc-m68k.h (m68k_init_after_args): Declare.
3319 (tc_init_after_args): Define as m68k_init_after_args.
3320 * config/tc-m68k.c (m68k_init_after_args): New function,
3321 containing one-shot code from md_assemble. Added warning for
3322 combination of 68040 and 68851.

3337 and bfd_ecoff_set_regmasks to set the GP value and the register
3338 masks, rather than using the now obsolete fake .reginfo section.

3342 * listing.c (list_symbol_table): Don't print register symbols as
3345 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
3346 underscores, since symbol_new will already have done it.
3347 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
3349 * as.c (main): If tc_init_after_args is defined, invoke it after
3350 all arguments have been processed.
3352 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
3353 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
3354 section instead of .text. Call create_target_segments.

3357 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3359 * config/tc-mips.c (append_insn): Permit branches to be switched
3360 with the preceding instruction even if .set nobopt has been seen.
3361 .set nobopt actually controls whether to bring up an instruction
3362 from the branch target, which gas does not currently support.

3403 * config/tc-hppa.c (pa_parse_space_stmt): Use the built-in
3404 defaults for defined, private, and spnum fields for the

3420 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3422 * expr.c (operand): Try to parse "0f" and "0b" sequences as
3423 floating point and binary numbers respectively; if it doesn't
3424 work, treat them as local labels.
3426 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
3427 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
3429 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
3431 * vmsconf.sh: In generated file, get ".obj" suffix right, build
3432 source files from other directories into objects in the current
3433 directory, and specify PSECT attributes explicitly to linker.
3434 Also added missing label.
3435 * Makefile.in (stamp-mk.com): Reference new variable
3436 VMS_OTHER_OBJS for list of non-local object files, instead of

3451 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
3452 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
3453 argument, the reloc type.
3454 (load_register): Pass reloc type to macro_build for 'u'.
3455 (macro): Likewise. For M_LA_AB permit a difference expression
3456 when generating embedded PIC code between an arbitrary symbol and
3457 a symbol in the .text section.

3467 * subsegs.c (subsegs_begin): Call memset with args in the correct
3469 (subseg_get): Clear newly allocated seginfo, set its pointer slots
3470 to NULL instead of 0.

3474 * config/tc-hppa.c (pa_procend): Handle case where label was
3475 defined after the .proc directive.

3499 (hppa_tc_symbol): Likewise.
3501 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
3502 elf_tc_make_sections stuff. It was there to support PA braindamage
3503 which has been fixed, and in the case of elf_tc_make_sections is
3504 redundant with elf_tc_final_processing.
3506 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3508 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

3518 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
3519 value into the file if the fixup will not generate a reloc.
3521 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
3523 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
3524 don't spew remainder of input file in error message.
3525 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
3526 message with reloc type and try to process remainder of file.
3528 * doc/Makefile.in (install-info-as, install-info-gasp): New
3529 targets, now explicitly checking $(srcdir) for info files.
3530 (install-info): Depend on both of them; do nothing more.

3534 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
3536 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3538 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
3539 flag rather than signedp field. Only permit extended range if
3540 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
3541 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
3543 * config/tc-ppc.c (ppc_size): New static variable.
3544 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
3545 (md_begin): If an instruction has a size specific flag set, only
3546 add it if we are assembling that size.
3548 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3550 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
3551 cross section PC relative relocs right for COFF and ELF.
3553 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3555 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
3556 (OBJ_PROCESS_STAB): Don't define.

3560 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
3561 the type of symbol set symbols which happen to be in the absolute
3562 or undefined section.
3564 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
3566 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
3567 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
3568 and -many (all architectures).
3570 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3572 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
3573 involving a function symbol which is not a plabel to zero.
3574 (md_apply_fix): Never pass a function symbol to field_adjust.
3576 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3578 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
3579 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
3581 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
3582 branch with an instruction that uses $at, in case the branch is
3584 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
3585 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
3586 to make it pcrel_offset.
3587 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
3588 reloc->address; another gruesome hack to get gas reloc handling to
3591 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3593 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
3596 (emit_insn): New function.
3597 (md_assemble): Call it.
3598 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
3600 (lituse_pending): New variable. Set by anything that generates a
3601 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
3602 tested by code that might want to emit a LITUSE reloc.
3603 (emit_unaligned_io): New function. Currently calls md_assemble,
3604 but it should eventually be converted to generate the insn itself
3605 and call emit_insn directly.
3606 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
3607 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
3608 emit_bis_r): Likewise.
3609 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
3610 (alpha_ip, label get_macro): Don't emit the final instruction if
3612 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
3613 unaligned memory access macros.
3614 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
3615 the value can't be resolved.
3617 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3619 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
3620 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
3621 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
3623 (mips_force_relocation): New function.
3624 (md_apply_fix): Set fixP->fx_done appropriately.

3633 * config/tc-mips.c (enum mips_pic_level): New enum.
3634 (mips_pic): Change from int to enum mips_pic_level. Change all
3635 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3636 (load_address): Handle EMBEDDED_PIC.
3637 (macro): Handle EMBEDDED_PIC in all PIC cases.
3638 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3639 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3640 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3641 works). Do not permit -G with SVR4_PIC.
3642 (s_abicalls): Warn if -G was used, and force -G 0.
3643 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3644 anything but a.out, not just for ELF. For ECOFF, don't generate a
3645 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3647 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3649 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3651 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3652 parameters to avoid losing when compiling with HP CC.
3653 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3655 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3657 * Makefile.in (config-stamp): If `defs' is defined, emit a
3658 preprocessor directive to create a macro named by this value into
3659 config.new; don't explicitly go for BFD_ASSEMBLER.
3660 * configure.in: Define `defs', not `BFDDEF'. Set it to
3661 MANY_SEGMENTS for any obj-coffbfd target.
3662 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3663 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3665 (LOCAL_LOADLIBES): Deleted.
3666 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3667 * config/m88kcoff.mt (TDEFINES): Ditto.
3668 * config/ebmon29k.mt: Deleted.
3669 * config/h8300hds.mt: Deleted.
3670 * config/ic960coff.mt: Deleted.
3671 * config/sparc.mt: Deleted.
3672 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3673 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3674 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3675 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

3688 * Makefile.in (STAGESTUFF): Add gasp.new.
3690 Fri Mar 18 20:09:16 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3692 * write.c (symbol_table_frozen): New variable, to be set after
3693 bfd_set_symtab is called.
3694 (dump_section_relocs): Note whether a symbol is a section symbol
3696 (adjust_reloc_syms): For now, always supply an absolute symbol for
3697 fixups without symbols but not yet `done'. Use section_symbol to
3698 get the symbol, instead of going directly for abs_symbol.
3699 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3700 reloc is not a section symbol and is not in the symbol table.
3701 (set_symtab): New function, broken out from write_object_file.
3702 Counts symbol table instead of relying on an earlier count.
3703 (write_object_file): Call set_symtab, but do it after potentially
3704 invoking the *_frob_file macros. Don't bother counting symbols.
3705 Call symbol_remove, instead of expanding it in place. Moved the
3706 conditionalized `object_file_size' declaration down to
3707 conditionalized block where it's used. When using the absolute
3708 symbol for a fixup without a symbol, set sy_used_in_reloc.
3709 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3710 the correct symbol for the absolute section.
3712 * subsegs.c (section_symbol): Use symbol_new instead of
3713 symbol_make, since we may want it to go into the symbol table.
3714 Make the new symbol have internal linkage. If
3715 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3716 symbol with the newly created GAS symbol.
3717 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3718 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
3720 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
3722 * config/tc-sparc.c: Include subsegs.h.
3723 (in_signed_range): New function.
3725 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3726 (sparc_ip, label "immediate"): Reject constants for pcrel
3727 instructions only if the relocation type indicates a "call"
3728 instruction and the offset is within range of a "jmpl %g0". If
3729 it's not in range, use the absolute section symbol plus an offset.
3730 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3732 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3734 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3737 * configure.in: Eliminated all targets using obj-coff but not
3738 defining BFD_ASSEMBLER; I think all such targets that are
3739 supported will be matched by real CPU-OS combinations earlier in
3741 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
3742 some comments about the dpx2 configuration, but left it disabled,
3743 since it couldn't be reached before.
3744 (target a29k-amd-ebmonold): Deleted.
3746 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3748 * config/tc-hppa.c (pa_import): Correctly handle importing of an
3749 already defined symbol.

5590 BFD_RELOC_MIPS_GPREL. Added new case a.
5591 (set_at, load_register, macro): Changed calls to macro_build to
5592 pass new argument for i, j and o cases.
5593 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
5594 special handling when generating SVR4 PIC code.

5928 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
5930 * configure.in: Set bfd_gas for all sparc targets. Added facility
5931 for keeping or rejecting configurations still under development;
5932 default is to assume production environment, and reject configs
5933 still being worked on. Mark Elf configurations (except sparc and
5934 i386) as developmental. Deleted cases matching some generic names
5935 in favor of more specific names. (E.g., when we get Alpha

5953 for functions only used within tc-hppa.c, likewise for structures,
5954 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
5955 conditional code in a few small places.

5961 into a few places. Make all functions and variables which
5962 are only used within tc-hppa.c static. PARAMize all functions.
5963 Add comments to functions. Delete unused functions, variables,
5964 #defines, etc. Delete unused members within structures. Delete
5965 ldil;ble hacks -- it is believed they were installed to work
5966 around old gas bugs. Avoid using mixed case for local
5967 functions, variables, and structures. Fix formatting problems
5968 not found by GNU-indent. Add FIXME notices for things which
5969 should be worked on the near future. Delete lots of old
5970 useless (1.36 PA-SOM) code.

6049 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
6051 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
6052 ELF, since the ELF object format does not have these type of
6053 relocations. Change the abort into as as_bad and return
6054 BFD_RELOC_NONE to silence compiler warnings.
6055 (md_assemble): Keep track of the instruction size. Allow white
6056 space between the $ and the constant for compatibility with older
6057 gases and other assemblers.

7132 * Extensive changes to permit symbols to contain any expression
7133 type and to delay the computation of the expression until the
7134 value is actually needed. This permits setting symbols to values
7135 calculated based on object code size. Expressions were changed to
7136 no longer be in a section, to stop the overloading of segment and
7137 expression type that previously occurred.
7139 * as.c (big_section, pass1_section, diff_section, absent_section):
7141 (expr_section): Added (used for dummy symbols which hold

8404 references don't appear to work right.
8406 * as.h (const, volatile): Put these definitions back, and use
8409 * doc/as.texinfo: First pass at using new texinfo features --
8410 variables, conditional tests. Far from complete.
8412 Mon Mar 29 16:05:40 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
8414 * read.c: Temporary hack to handle some 64-bit constants. This
8415 should be redone later.

8436 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
8437 the bottom (make expands variables in dependencies when the
8438 dependencies are read, not when they are used).
8440 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
8441 a29k .bss section; the mondfe program doesn't like it.

8462 source directory, if that's not the current directory.
8464 * configure.in (per-host): Accept MIPS host with BSD version

8486 process relocs if there aren't any relocs to process. Avoids
8487 malloc/free bug on SCO too.

8490 avoid some redefinition complaints on some systems.
8491 (const, volatile): Don't need these conditionally defined if we
8492 use CONST and VOLATILE from ansidecl.h.
8493 (seg_name): Use CONST, not const.
8495 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
8497 * config/tc-mips.c: Reindented to GNU standards.
8499 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
8501 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
8502 (fixup_segment): Add a29k special case; the linker is not prepared
8503 to see a segment offset here.
8505 * app.c (do_scrub_next_char): Added new state, 10, modifying state
8506 9 to only keep a space in between identifier characters.
8508 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
8510 * Makefile.in: add dvi target; as-$(config).texinfo might live in
8511 srcdir, might be in objdir.
8513 * doc/Makefile.in: dvi depends on as.dvi

8531 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
8532 bignums, but don't emit error message.
8534 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
8536 * Makefile.in (targ-cpu.o): Depend on config.h.
8538 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
8540 * app.c (do_scrub_next_char): Added new state, 9, to avoid
8541 dropping a space immediately following an identifier.
8542 * expr.c, write.c: Rewrote assert expressions to not use multiple
8543 lines; I don't think that can be done portably.
8544 * config/tc-mips.c (macro): Use $AT if target register is zero in
8545 load instruction, which it can be for a floating point load.
8547 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

8558 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
8559 z8k-opc.h, not z8k.h.
8561 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
8564 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8566 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
8568 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
8570 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
8571 to be on a single line.

8615 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
8616 (struct loc, struct proc, struct file): Moved to tc-mips.c within
8617 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.

8619 prototypes for all static functions. Moved existing minimal
8620 debugging format support info #ifndef OBJ_ECOFF blocks.
8621 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
8622 does not support a non sign extended high 16 bits reloc. Adjusted
8623 all callers accordingly.
8624 (tc_get_register): Renamed from get_register, and made non-static.
8626 * config/mips-big.mt, config/mips-lit.mt: New files. Define

8669 * make-gas.com: Find obstack.obj if it's not in the current
8671 * read.c (s_ignore): Don't declare is_end_of_line. It's
8672 redundant, and triggers a VMS gcc compiler bug.
8674 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
8675 current segment as an argument. (Ignored in all cases but VMS.)
8676 All callers and definitions changed.

8694 argument to s_ignore. Put "#if 0" around unused code.
8695 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
8696 Call elf_xstabs for .stabs and .xstabs operators.
8698 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
8700 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
8703 * configure.in: mips-bsd configuration was missing format spec.
8706 * Makefile.in (Makefile): Depends on configure.in.
8708 * config/tc-mips.c (append_insn): Don't check for alignment of
8709 frag in memory; alignment of instructions in section is a separate
8712 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI

8729 * config/tc-sparc.c (s_xword): Now call big_cons, so large
8730 constants are accepted, but symbolic values are not. GCC will not
8731 generate the latter currently.
8733 * frags.c (frag_init): New function.
8734 (zero_address_frag, bss_address_frag): Now initialized at run
8736 * as.c (main): Call frag_init.

8780 (fixup_segment): Make sure common-section symbols get treated the
8781 same as undefined symbols.
8782 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type

8812 new section/subsection.
8814 * read.c: Don't include ctype.h.
8815 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
8816 for now; should be machine-dependent.
8818 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
8819 targets, forcing BFD use.

8841 (write_object_file) [! BFD_ASSEMBLER]: Call it.
8842 (relax_and_size_seg) [BFD_ASSEMBLER]: New function; relax section
8843 and set its size and flags.
8845 * struc-symbol.h (struct symbol) [BFD_ASSEMBLER]: Replace some

8988 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
8989 latter, instead of selecting with preprocessor conditionals.
8991 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8993 * configure.in: recognise all sparclite variants

9001 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
9003 * expr.c (operand): If character other than comma or newline is a
9004 logical end-of-line character, use the newline case.
9005 From Eric Youngdale:
9006 (operand): Set X_add_number field for floating-point numbers.
9007 (operand): Treat zero byte as end-of-operand.
9009 * configure.in (per-target): Look for with_bfd_assembler option.
9010 For now, only accept "no", until the merge is done.
9012 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
9013 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
9014 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
9015 * read.c: Finish conversion to S_* macros in the VMS only
9016 parts of the program. Add "const" modifier to hex_value.
9017 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
9019 * expr.c: Add "const" modifier to hex_value.
9020 * symbols.c: Finish conversion to S_* macros in the VMS only
9021 parts of the program. Add "const" modifier to
9022 md_[long,short]_jump_size. Remove declaration of const_flag
9023 (which will be declared in obj-vms.h).
9024 * write.c: Add "const" modifier to md_[long,short]_jump_size.
9025 Fix arguments to VMS_write_object_file.
9026 * config-gas.com: New file. Script for VMS systems to set up the
9027 configuration to build gas for VMS, and create config.status.
9028 * make-gas.com: Redone to work with new scheme.
9029 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
9031 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
9032 will swap bytes if needed on a big endian system. Use throughout
9034 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
9035 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
9036 types of malformed stabs. Change parsing algorithm so that we are
9037 more certain of having all of the information that we need on hand.
9038 * obj-vms.c (final_forward_reference): New function, used to help
9039 resolve the data types of as many struct elements as possible
9040 when some part of the struct is not fully defined by the compiler.

9043 * obj-vms.c (VMS_write_object_file): Define all vtable psects
9044 as symbols as well in the object file. Look for external functions
9045 that start with "__vt.", and turn them into variables, since the
9046 g++ compiler is incapable of doing this.
9047 * tc-vax.c: Add '1' option for backward compatibility with older GCC
9049 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
9050 * input-scrub.c (as_where): Fix bug where as would crash if we did not
9051 have the name of the source file yet.
9052 * config/ho-vms.h: define HO_VMS, not HO_VAX.
9054 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
9056 * read.c (s_data): Always use "data_section", since it'll map to
9057 SEG_DATA or SEG_E1 if needed.
9058 (s_lcomm): Likewise with bss_section.
9059 (s_fill): Use memset, not bzero.
9061 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

9082 (section_alignment): Declare only if not BFD_ASSEMBLER.
9083 (big_section, reg_section, pass1_section, diff_section,
9084 absent_section, text_section, data_section, bss_section): If
9085 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
9086 mapping to segT enum values.
9087 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
9088 if these are used or defined, if BFD_ASSEMBLER.
9089 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
9090 subseg_new split into two functions.
9091 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
9093 * as.h (volatile): Don't define if already defined.
9094 (had_errors, had_warnings): Provide prototypes for ANSI C even if
9096 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
9097 declare with format attribute for -Wformat checking.
9099 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
9101 * app.c, config/tc-*.c: Don't include read.h, since it is already
9104 * These are based on patches from Minh Tran-le
9105 <mtranle@paris.intellicorp.com>.
9106 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
9107 obj_format coffbfd and gas_target i386coff for target.
9108 (i[34]86-*-isc*): New host (uses sysv).
9109 * config/i386aix.mt: Removed (no longer used).
9110 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
9112 (LDFLAGS): Added, defined as -shlib.
9113 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
9114 * config/te-sco386.h (LOCAL_LABEL): Don't define.
9115 (DOT_LABEL_PREFIX): Define.
9116 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
9117 name rather than L0\001.
9118 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
9120 * symbols.c, symbols.h (local_bss_counter): Removed.
9121 * write.c (write_object_file): bss no longer uses

9129 (size_section): Restored sanity check.
9130 (do_relocs_for): Base section address on s_paddr rather than
9131 computing it. Adjust a29k R_IHIHALF special case to account for
9132 section paddr (used to require paddr to be zero). If there are no
9133 reclos, set s_relptr to 0. Set relocation size in object_headers.
9134 (fill_section): Always set s_vaddr here, removing
9135 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
9136 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
9137 Set STYP_INFO for .comment.

9141 H_{SET,GET}_* macros.
9142 (do_linenos_for): Set lineno size in object_headers.
9143 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
9144 set s_vaddr here. If string_byte_count remains 4, set it back to
9145 0, and only write strings out if there are some. Call
9146 fill_section before do_relocs_for and do_linenos_for.
9147 (obj_coff_section): Handle optional quoted second argument giving
9148 section characteristics.
9149 (obj_coff_bss): Added to handle .bss.
9150 (obj_coff_ident): Added to handle .ident (puts string in .comment

9170 (do_scrub_next_char): For \", return " not '.
9171 (symbol_chars): Now const.
9173 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
9174 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
9176 * config/obj-coff.h: Don't use #elif.
9178 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
9179 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
9181 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
9183 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

9205 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
9206 using ZERO_BASED_SEGMENTS.
9207 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
9208 never set segment address for SEG_E2 (.bss) and don't write out
9209 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
9210 (obj_coff_endef): Don't merge labels or symbols awaiting forward
9211 definitions, and don't merge tags with non-tags. Check for .bf
9212 rather than just checking whether the second character is b and
9213 the third character is f.
9214 (obj_coff_val): gcc can generate values which we don't handle
9215 correctly; discard information for now, since it only affects the
9216 debugging information.
9217 (tag_find_or_name): Don't insert tags in the symbol table.
9218 (yank_symbols): Don't merge labels.
9219 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

9367 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9370 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

9397 consistently const, and always initialized them. Included read.h.
9399 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
9401 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
9402 constant will not fit in an immediate field.
9403 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
9405 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

9422 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
9423 so widening works consistently.
9425 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
9427 * version.c: Put conditional "const" before version_string, not

9438 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
9440 * Support for i386-sysv.
9441 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
9442 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
9443 be used to set them all to zero as was done before.

9445 (fill_section): Don't set STYP_NOLOAD for .bss section.
9446 (fixup_segment): 386 uses strange common symbol format.
9447 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for

9483 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
9484 #elif, since it is not supported by old compilers.
9485 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
9486 couple of expressions in tc-m68k.c.
9488 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9490 * read.c (cons): If NO_RELOC is defined, use it.
9492 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
9494 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
9496 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
9497 local labels to start with a .) and set REGISTER_PREFIX to %.
9498 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

9516 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
9517 sections starting from zero, rather than making them consecutive.
9518 This makes subsequent reloc calculations easier, esp if the object
9519 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
9520 allocate lcomm in .data rather than in .bss. It seems that some
9521 tools can't cope with a non-zero sized bss before linkage.
9523 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9525 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

9544 * Makefile.in (install): if $(tooldir) exists, install as in
9547 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
9549 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
9550 .word is < -32768 or > 32767. The -J flag causes the error to be
9551 ignored. This is to catch over-sized switches generated by gcc on
9552 systems which don't support the broken .word hack.
9553 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
9554 write.c (fixup_segment): check for signed .word overflow if
9555 WARN_SIGNED_OVERFLOW_WORD.
9557 * write.c (fixup_segment): fixed missing parens in expression

9574 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
9576 * input-scrub.c (input_scrub_push): call input_file_begin, not
9578 messages.c (as_perror): print ": " between the passed in error and
9579 the strerror, like perror does.
9581 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

9584 From Steve Chamberlain:
9585 Makefile.in: Handle m68*-*-coff*.
9586 read.c, read.h: add mult argument to s_space
9588 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
9589 Motorola and MIT syntax; gas can now assemble either type of
9591 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

9598 (fixup_segment) set fx_subsy to 0.
9599 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
9601 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
9604 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9606 * Makefile.in (LIBS): Include opcode library.

9631 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9633 * config/tc-m68k.c (init_table): Now const. Always include 68851
9634 data, so that "bc" is available to 68040 cache instructions.
9635 Added "tt0", "tt1", and 68ec030 variants.
9636 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9637 (enum _register): Added TT0, TT1.
9638 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9639 line number correctly in "internal error" messages. Don't print
9640 architecture-mismatch message for operand errors.
9642 From Colin Smith (colin@wrs.com):
9643 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

9665 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9666 has already been formatted (but may still contain %-characters).
9669 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
9671 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
9672 written with indirection on the last two operands, which can be
9673 either data or address registers. Added a new operand type 'r'
9674 which accepts either register type. Added '(' to notend stuff in
9675 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

9694 their not having symbols associated.
9696 * tc-i960.c (norelax, instrument_branches): Default initializer is

9722 being used with args swapped, causing occasional lossage when
9723 refilling buffers after an include file.

9733 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
9734 selected architecture, print a message saying so and listing what

9781 * expr.c (floating_constant): Separate "=-" to avoid confusing
9782 ancient or broken compilers.
9784 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
9785 processor/opcode mismatch, so reword the error message.
9786 (md_assemble): If no CPU has been set (even if FPU/PMMU
9787 characteristics have been), default to 68020. Don't need extra
9788 quotes around error string.

9851 68010 bxx into a bra+6 jmpxx, put the bytes of the jmp opcode into
9852 the right place. (s_bss): Don't put .bss stuff into SEG_DATA, put
9855 Thu Jun 4 11:59:13 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9857 * expr.c(expr): allow SEG_REGISTER in expressions.
9858 * read.c(pseudo_set): register expressions can be the source of a
9860 * subsegs.c (subseg_new): Now -R forces all changes to SEG_DATA to
9861 goto SEG_TEXT (if a.out)
9862 * write.c (write_object_file): If a.out don't use the old way for
9864 * config/obj-a.out (s_sect): complain if the user tries to use a
9865 subsegment with a value which might interfere with out -R hackery.
9866 * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
9867 rather than use ugly if tree. (init_regtable): insert register
9868 names into symbol table.
9870 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
9872 * write.c (write_object_file): keep the fix_tail clean, which
9873 fixes a bug in -R where relocations were being lost.
9875 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
9877 * configure.in: recognize m680x0 as having sun3 emulation mode for
9878 vxworks environment.
9880 Sun May 31 05:33:00 1992 david d `zoo' zuhn (zoo@cygnus.com)

9900 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9902 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
9903 calc the base of relocs correctly.
9904 * tc-a29k.c (parse_operand): allow expressions to be in any section.
9906 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
9908 * as.c, write.c: use -K rather than -k for the broken word warning
9911 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
9913 * Makefile.in: do not print recursion lines.
9915 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9917 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
9919 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
9921 * write.c (write_object_file): For b.out format, round up section
9922 start addresses to match required alignment.
9924 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
9926 * Makefile.in (install): Install into $(tooldir)/bin, since that's
9927 where gcc looks for it.
9929 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
9931 * Makefile.in: Changed some lines to be less confusing for some
9934 * input-file.c: Conditionalize on _IOFBF, not VMS.
9936 * read.c, write.c: Change a series of ifdef/elif to
9937 ifdef/else/ifdef etc.
9939 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
9941 * symbols.c (fb_label_init): fix sizeof to memset.
9943 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
9945 * Makefile.in: install the man page.
9947 * Makefile.in: pass down MAKEINFO explicitly on info.

9951 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9953 * flonum-const.c: renamed flonum-konst.c to stop dos name
9956 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
9958 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
9959 tc-m68k.h to te-sun3.h.
9961 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
9963 * configure.in: vxworks68 gets te-sun3.h.
9965 * expr.c: remove limitation that local_labels_dollar or
9966 local_labels_fb must be < 10.
9968 * symbols.c: remove local_labels_dollar, replace with a function
9969 interface for a sparse array. All users adjusted.
9971 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
9973 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9975 * doc/Makefile.in: commented out line for building as-all.texinfo.
9978 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
9980 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

9992 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
9994 * Makefile.in (strerror.o): Add rule so that broken Sun make can
9997 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
9999 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
10001 * expr.c (operand): if can't work out what sort of operand it is,
10002 then look through FLT_CHARS for a hint.
10004 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
10006 * Makefile.in, configure.in: removed traces of namesubdir,
10007 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10008 copyrights to '92, changed some from Cygnus to FSF.
10010 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
10011 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10012 copyrights to '92, changed some from Cygnus to FSF.
10014 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10016 * expr.c: If an expression is single comma, then return with
10017 SEG_ABSENT rather than an error - since the sparc front end does
10018 really strange things with things like fbge,a
10020 * as.h: include bfd.h if using many sections
10021 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
10022 local labels didn't work.
10023 * listing.c (list_symbol_table): don't core dump when there's no
10025 * write.c, write.h: call fix_new with the right number of args on
10027 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
10030 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10032 * app.c: MRI compatibility - allow single quote to start a string.
10033 * as.c: fix typo recently introduced.
10034 * as.h : Don't include aout/reloc.h - it's not right for COFF!
10035 * expr.c: Much rewriting, to accomodate MRI syntax for
10036 expressions. Also easier to read now.
10037 * listing.c: Put back defuns
10038 * read.c: modified to accept MRI syntax, put back listing pseudo
10039 ops so that an assembler built with NO_LISTING ignores list ops
10041 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
10042 machine is a SPARC or a 29K.
10043 * config/obj-aout.c: added s_sect pseudo op
10044 * config/obj-coffbfd.c: lints, set the filehdr flags right and
10045 fill in the timestamp.
10046 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
10047 anymore, define all the relocs which the tc-<x> bit will use so we
10048 can translate from them to the coff types.
10049 * config/tc-a29k.c: reloc_type isn't ane enum any more
10050 * config/tc-m68k.c: Added NO_RELOC definition.
10052 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10054 * Makefile.in: put header files before C source for TAGS; remove
10055 references to non-existent syscalls.h.
10057 * read.c, write.c subsegs.c: back out the .bss changes.
10059 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
10061 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
10063 * a.out.h: removed.
10065 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
10067 * symbols.c (local_label_name): symbols now start with ^A.
10069 * read.c, subsegs.c, write.c obj-coff.c: added handling of
10070 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
10071 generate these sections. .align: will use NOP_OPCODE or 0
10072 for padding. This is just for being nice to the
10075 * expr.c (operand): changed to generate local label "\001L0"
10076 starting with a ^A so that it is recognized as a local label.
10078 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
10080 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
10081 i/o opcodes - inb, inw, outb and outw. string manipulation with
10082 att syntax - scmp, slod, smov, ssca, ssto.
10084 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
10085 to just after .file .
10087 In obj_crawl_symbol_chain() where it tries to put the external
10088 symbols apart, with the condition:
10089 (!S_IS_DEFINED(symbolP) &&
10090 !S_IS_DEBUG(symbolP) &&
10091 !SF_GET_STATICS(symbolP))
10092 it was moving too many symbols out. So I switch it back to the
10094 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
10096 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
10097 so that we don't use the F_RELFLG which make the linker complain
10098 that somebody has stripped the relocation info.
10100 Also, the AIX ld program require that the relocation table
10101 is sorted by r_vaddr like the standard ATT assembler does.
10103 [he also changed the sizeof(struct ...)'s into the coff
10104 style FOOSZ macros. I'm not sure this is right, but I can't
10105 remember why. xoxorich.]
10107 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
10109 * Makefile.in, configure.in, doc: use the doc. Build it, install
10112 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
10114 * read.c: white space and comments only.
10116 * configure.in: use the new atof-ns32.c for ns32k.
10118 * write.c: comment change only.
10120 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
10121 aren't yet integrated.
10123 * tc-i860.[hc]: blew off the dust. Something must still be done
10124 about conflicting relocation types.
10126 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
10129 * tc-i960.c, tc-sparc.c: white space and comments only.
10131 * tc-a29k.h: delete duplicate macro definition.
10133 * new file atof-ns32k.c copied from hack's last unreleased gas.
10135 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
10137 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
10140 * nearly everything. flush ChangeLog, package as gas-1.92.1.
10141 ChangeLog's prior to this are sketchy at best. I have logs.
10142 They just aren't ChangeLogs.
