1517 Add a space after "pc-relative" in the error message.
1518 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
1519 BFD_RELOC_386_GOTOFF relocs.

1561 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1563 * configure.in: Set bfd_gas for all sparc targets in one place,
1564 instead of separately for each. Correctly handle user-supplied
1565 "--enable-bfd-gas" option.
1567 * gdbinit.in: Move "break abort" to end, in case gdb complains.
1569 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:

1577 (indent_level): No longer static.
1578 (print_symbol_value_1): Don't print frag address if it matches

1582 (print_expr_1): Fix whitespace before printing X_add_number.
1584 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1585 not symbol_new, for symbols holding expression values.
1586 * expr.h (make_expr_symbol): Move declaration here.
1587 * write.c (fix_new_exp): Handle O_add by creating an
1588 expression-valued symbol, and calling fix_new_exp recursively.
1589 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1590 undefined symbol and a constant, fold the constant into the fixup,
1591 and refer to the undefined symbol directly. Then process the
1592 fixup again from scratch.
1593 (write_object_file): Before calling adjust_reloc_syms, make a pass
1594 through the symbol list trying to resolve values.
1596 * write.c (print_fixup): New routine, for debugging.
1597 (write_relocs): Call bfd_install_relocation. Deleted various
1598 hacks for working around problems with bfd_perform_relocation.
1600 * Makefile.in (VERSION): Update to 2.4.90.
1602 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

1615 * write.c (write_relocs): Add file name and line number to
1616 as_fatal calls. Handle bfd_reloc_overflow case specifically when

1619 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1621 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1622 here. Use them for deciding which PRINTF*LIKE macro definitions
1624 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
1625 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1626 default definitions matching what we were doing before.
1627 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1628 always use the varargs form if not using stdarg. It's safe to
1629 always use vfprintf, because libiberty will provide it if the
1630 native system doesn't. Also, always make format be const.
1631 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

1646 (listing_newline): Check filename as well as line number when
1647 deciding whether to record it.
1648 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1649 false (if defined) as well as checking for reg_section.
1650 (listing_listing): Iterate fetching lines while line number is too
1651 low, and we haven't run off the end of the input file.
1653 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1655 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1657 * ecoff.c (ecoff_generate_asm_lineno): check if

1659 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
1662 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1664 * config/ho-*.h: Now-unused files deleted.
1666 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1667 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1668 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1669 zero. Don't call obj_frob_forward_symbol.
1670 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
1671 X_add_number is zero.
1672 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1674 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1676 (strchr): Don't declare.
1677 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
1678 md_estimate_size_before_relax, md_ri_to_chars,
1679 md_create_short_jump, md_create_long_jump.
1680 (brtab_emit): Use data_section, not SEG_DATA.
1682 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1684 * config/vms-conf.h: new file, manually derived from conf.in.
1685 * config-gas.com: use it, and eliminate obsolete "host.h".

1689 * config/tc-ppc.c (ppc_current_block): New static variable.
1690 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to

1694 (ppc_es): Clear ppc_current_block.
1695 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1696 from the csect of the enclosing block.
1698 * config/tc-mips.c (insns_since_cache_access): Remove.
1699 (append_insn): Remove setting of insns_since_cache_access, and
1700 special 4600 handling; it turns out not to be required.
1702 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1704 * config/tc-mips.c (md_shortopts): Remove E.
1705 (md_longopts): Add EB and EL.
1706 (md_parse_option): Handle -EB and -EL as separate options, rather
1707 than as a single -E option with an argument.

1716 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1718 * configure.in: Test for remove, not delete. Fix cross-assembler
1720 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
1723 * read.c (pseudo_set, case O_symbol): If
1724 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1725 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1726 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.

1730 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1731 many others): new macros; values obtained from "DSTRECRDS.SDL".
1732 * config/obj-vms.h (various): use them.
1733 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1734 representation (only enum bitfields can avoid being bitstrings).
1735 (bitfield_suffix, setup_basic_type): new routines.
1736 (VMS_typedef_parse): use them. Now recognize bitfields of all
1737 integral types, not just type `int'. Caveat: the representation
1738 used for bitfields still does not work for objects placed in
1739 registers, and gcc's optimizer sometimes puts small structs there.
1741 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1743 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1744 bit from const_flag.
1745 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
1746 (tc_frob_label): define this to call vms_check_for_special_label,
1747 and declare the latter.
1748 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1750 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1751 (vms_check_for_special_label): new routine (tc_frob_label).
1752 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1753 and `gcc2_compiled.' labels; they won't reach here any more.
1754 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1755 double', use `vax_g_doubles' flag to select type of double.
1756 (VMS_write_object_file) [traceback setup]: don't pass symbols
1757 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1758 and TBT_Routine_End functions.

1762 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1763 S_GET_VALUE() to avoid many repeated function calls.
1764 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1765 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1766 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1767 be obsolete; gcc does it automatically for vms target. It's
1768 also misnamed, because it is for the "VAX C" run-time library,
1769 not the newer "DEC C" one which has much different startup code.]
1770 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1771 `S_GET_xxx(symbol) = new_value'.
1773 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1775 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1776 not &bfd_abs_section.
1778 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1780 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1782 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1784 * expr.c (expr): Don't reduce the difference of two symbols in the
1785 same frag if the symbols are not in normal sections.
1787 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1788 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1789 (obj_attach_unwind_info): Do not define. Not needed anymore.
1790 * config/tc-hppa.c: Delete whitespace at EOL.
1791 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1792 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1793 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1794 fixups, store 32bits of unwind information in the fx_addnumber
1796 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
1797 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
1798 pointer to 32 bits of unwind info.
1799 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
1800 pointer to the dummy symbol; set the addend field to fx_addnumber.
1801 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
1802 rather than &bfd_XXX_section.
1804 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1806 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
1807 value by one; discard adjustments previously being made. From
1810 VMS- and Vax-related changes from Pat Rankin:
1811 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
1812 * vmsconf.sh: no longer have make-gas.com echo text about needing
1813 to modify the gcc-vms driver when intending to use with gcc 1.x.
1814 * as.c (parse_options): suppress 'v' from std_short_options and
1815 eliminate VMS-specific conditional initialization;
1816 [default case]: check for '-v' if md_parse_options doesn't recognize

1820 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
1821 for O_big literal operands (double floats and long long ints);
1822 [VMS, md_shortopts]: add second colon after 'v';
1823 (md_parse_options) [VMS, case 'v']: check for argument, so
1824 caller can handle `-v' w/o arg.

1828 * config/obj-coff.c (do_relocs_for): If TC_KEEP_FX_OFFSET
1829 is defined, put the tx_offset into the r_offset.

1865 (parse_args): Use them always.
1866 (main): Use exit rather than return.
1868 * Makefile.in (*_FOR_TARGET, INSTALL_XFORM, install, uninstall):
1869 Rewrite handling of program_transform_name.
1871 * configure.in: Test for functions unlink and delete.

1877 * .gdbinit: Deleted.
1878 * aclocal.m4 (GAS_GDBINIT): Deleted.

1882 to ensure that older versions of autoconf aren't used.
1883 * Makefile.in: Added @configure_input@ line.
1884 (configure): Deleted rule.
1886 Tue Sep 13 12:08:20 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1888 * config/obj-coff.c (fixup_segment): After handling the difference
1889 of two symbols from the same segment, set fx_subsy to NULL, to

2949 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
2950 for gcc2's predefined types "long double" (same as double, as

3197 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,

3317 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
3319 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>

3322 source files from other directories into objects in the current
3323 directory, and specify PSECT attributes explicitly to linker.
3324 Also added missing label.

3345 (macro): Likewise. For M_LA_AB permit a difference expression
3346 when generating embedded PIC code between an arbitrary symbol and
3347 a symbol in the .text section.
3348 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and

3389 (hppa_tc_symbol): Likewise.
3391 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
3392 elf_tc_make_sections stuff. It was there to support PA braindamage
3393 which has been fixed, and in the case of elf_tc_make_sections is
3394 redundant with elf_tc_final_processing.
3396 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3398 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

3414 don't spew remainder of input file in error message.
3415 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
3416 message with reloc type and try to process remainder of file.
3418 * doc/Makefile.in (install-info-as, install-info-gasp): New
3419 targets, now explicitly checking $(srcdir) for info files.

3424 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
3426 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3428 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
3429 flag rather than signedp field. Only permit extended range if
3430 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
3431 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
3433 * config/tc-ppc.c (ppc_size): New static variable.
3434 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
3435 (md_begin): If an instruction has a size specific flag set, only
3436 add it if we are assembling that size.
3438 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3440 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
3441 cross section PC relative relocs right for COFF and ELF.
3443 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3445 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
3446 (OBJ_PROCESS_STAB): Don't define.

3450 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
3451 the type of symbol set symbols which happen to be in the absolute
3452 or undefined section.

3456 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
3457 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
3458 and -many (all architectures).
3460 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3462 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
3463 involving a function symbol which is not a plabel to zero.
3464 (md_apply_fix): Never pass a function symbol to field_adjust.
3466 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3468 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
3469 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
3471 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
3472 branch with an instruction that uses $at, in case the branch is
3474 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
3475 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
3476 to make it pcrel_offset.
3477 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
3478 reloc->address; another gruesome hack to get gas reloc handling to
3481 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3483 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
3486 (emit_insn): New function.
3487 (md_assemble): Call it.
3488 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
3490 (lituse_pending): New variable. Set by anything that generates a
3491 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
3492 tested by code that might want to emit a LITUSE reloc.
3493 (emit_unaligned_io): New function. Currently calls md_assemble,
3494 but it should eventually be converted to generate the insn itself
3495 and call emit_insn directly.
3496 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
3497 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
3498 emit_bis_r): Likewise.
3499 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
3500 (alpha_ip, label get_macro): Don't emit the final instruction if
3502 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
3503 unaligned memory access macros.
3504 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
3505 the value can't be resolved.
3507 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3509 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
3510 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
3511 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
3513 (mips_force_relocation): New function.
3514 (md_apply_fix): Set fixP->fx_done appropriately.

3523 * config/tc-mips.c (enum mips_pic_level): New enum.
3524 (mips_pic): Change from int to enum mips_pic_level. Change all
3525 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3526 (load_address): Handle EMBEDDED_PIC.
3527 (macro): Handle EMBEDDED_PIC in all PIC cases.
3528 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3529 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3530 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3531 works). Do not permit -G with SVR4_PIC.
3532 (s_abicalls): Warn if -G was used, and force -G 0.
3533 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3534 anything but a.out, not just for ELF. For ECOFF, don't generate a
3535 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3537 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3539 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3541 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3542 parameters to avoid losing when compiling with HP CC.
3543 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3545 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3547 * Makefile.in (config-stamp): If `defs' is defined, emit a
3548 preprocessor directive to create a macro named by this value into
3549 config.new; don't explicitly go for BFD_ASSEMBLER.
3550 * configure.in: Define `defs', not `BFDDEF'. Set it to
3551 MANY_SEGMENTS for any obj-coffbfd target.
3552 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3553 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3555 (LOCAL_LOADLIBES): Deleted.
3556 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3557 * config/m88kcoff.mt (TDEFINES): Ditto.
3558 * config/ebmon29k.mt: Deleted.
3559 * config/h8300hds.mt: Deleted.

3583 bfd_set_symtab is called.
3584 (dump_section_relocs): Note whether a symbol is a section symbol
3586 (adjust_reloc_syms): For now, always supply an absolute symbol for
3587 fixups without symbols but not yet `done'. Use section_symbol to
3588 get the symbol, instead of going directly for abs_symbol.
3589 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3590 reloc is not a section symbol and is not in the symbol table.
3591 (set_symtab): New function, broken out from write_object_file.
3592 Counts symbol table instead of relying on an earlier count.
3593 (write_object_file): Call set_symtab, but do it after potentially
3594 invoking the *_frob_file macros. Don't bother counting symbols.
3595 Call symbol_remove, instead of expanding it in place. Moved the
3596 conditionalized `object_file_size' declaration down to
3597 conditionalized block where it's used. When using the absolute
3598 symbol for a fixup without a symbol, set sy_used_in_reloc.
3599 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3600 the correct symbol for the absolute section.
3602 * subsegs.c (section_symbol): Use symbol_new instead of
3603 symbol_make, since we may want it to go into the symbol table.
3604 Make the new symbol have internal linkage. If
3605 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3606 symbol with the newly created GAS symbol.
3607 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3608 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

3613 (in_signed_range): New function.
3615 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3616 (sparc_ip, label "immediate"): Reject constants for pcrel
3617 instructions only if the relocation type indicates a "call"
3618 instruction and the offset is within range of a "jmpl %g0". If
3619 it's not in range, use the absolute section symbol plus an offset.
3620 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3622 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3624 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3627 * configure.in: Eliminated all targets using obj-coff but not
3628 defining BFD_ASSEMBLER; I think all such targets that are
3629 supported will be matched by real CPU-OS combinations earlier in
3631 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
3632 some comments about the dpx2 configuration, but left it disabled,
3633 since it couldn't be reached before.
3634 (target a29k-amd-ebmonold): Deleted.
3636 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3644 the 'j' operand if there are no further alternatives for this
3647 * config/obj-coffbfd.c (adjust_stab_section): Initialize
3648 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
3649 is not SEG_UNKNOWN rather than checking whether it is >= 0.
3651 * config/tc-mips.c (mips_align): Take new argument, label, and use
3652 it instead of global insn_label.
3653 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
3654 call to mips_emit_delay and pass it to mips_align.
3656 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3658 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
3660 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
3661 argument to a .callinfo directive. Don't loop forever on errors.
3663 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
3664 use pre-defined registers as arguments.

3669 S_IS_EXTERNAL when deciding whether to discard a symbol.
3671 * config-gas.com: Scan Makefile.in, not version.c, for current

3676 values to reduce number of lookups with S_GET_VALUE. Skip debug
3677 symbols to avoid "a really nasty bug". (From Holger Teutsch,
3678 holger@botbso.rhein-main.de.)
3679 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
3680 field. (Also from Holger Teutsch.) Watch for a would-be register
3681 mask that spans frags.
3683 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
3684 this_base, not line_base. (Patch from Andreas Arens,
3685 ari@obelix.av.rwth-aachen.de.)
3687 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
3688 look local if they're exported or undefined. Used to be done for
3691 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
3692 Get it from the looked-up symbol, instead of using the string from
3693 the input stream, which is no longer null-terminated.
3694 (LEX_PCT): New macro, defaults to 0.
3695 (lex_type): Use it for `%'.
3697 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
3698 (vip_op): Now static, and returns void. Callers changed. Added

3747 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
3748 0xffff for 'j' to be compatible with MIPS assembler. These
3749 numbers are actually treated as negative.

5450 an example of marker relocations.
5451 * write.c (write_relocs): Instead of assuming size of a relocation
5452 is 4 bytes, pick up the size from relocation itself.

5704 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
5705 the table, require that the one without bit 0x1000000 set come
5706 first. Require further that it be case 'b' or 'P'. The a29k
5707 opcode table already meets these constraints.
5708 (machine_ip): When handling case 'i' or 'A', make sure that the

5818 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
5820 * configure.in: Set bfd_gas for all sparc targets. Added facility
5821 for keeping or rejecting configurations still under development;
5822 default is to assume production environment, and reject configs
5823 still being worked on. Mark Elf configurations (except sparc and
5824 i386) as developmental. Deleted cases matching some generic names
5825 in favor of more specific names. (E.g., when we get Alpha

5843 for functions only used within tc-hppa.c, likewise for structures,
5844 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
5845 conditional code in a few small places.
5847 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
5848 structures, global variables, forward declarations together.

5850 conditional code -- try to group conditional code together
5851 into a few places. Make all functions and variables which
5852 are only used within tc-hppa.c static. PARAMize all functions.
5853 Add comments to functions. Delete unused functions, variables,
5854 #defines, etc. Delete unused members within structures. Delete
5855 ldil;ble hacks -- it is believed they were installed to work
5856 around old gas bugs. Avoid using mixed case for local
5857 functions, variables, and structures. Fix formatting problems
5858 not found by GNU-indent. Add FIXME notices for things which
5859 should be worked on the near future. Delete lots of old
5860 useless (1.36 PA-SOM) code.
5862 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
5863 field of the fixS structure. Needed to build unwind
5864 descriptors correctly.

5889 a multiple of the section alignment rather than always a
5892 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
5893 bits are zero (eg they specify no relocations), then do not even
5894 bother adding their entries to thesymextn section.

5939 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5941 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5942 ELF, since the ELF object format does not have these type of
5943 relocations. Change the abort into as as_bad and return
5944 BFD_RELOC_NONE to silence compiler warnings.
5945 (md_assemble): Keep track of the instruction size. Allow white
5946 space between the $ and the constant for compatibility with older
5947 gases and other assemblers.
5948 (i386_operand): Skip spaces between $ and expression.

6994 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
6995 *-*-solaris case, and move to before *-sysv* case that wants to

7022 * Extensive changes to permit symbols to contain any expression
7023 type and to delay the computation of the expression until the
7024 value is actually needed. This permits setting symbols to values
7025 calculated based on object code size. Expressions were changed to
7026 no longer be in a section, to stop the overloading of segment and
7027 expression type that previously occurred.
7029 * as.c (big_section, pass1_section, diff_section, absent_section):

7115 (previous_section, previous_subsection): New vars.
7116 (obj_elf_section): Save current place in case DWARF code wants us
7117 to pop back to it. Handle unquoted section name as well as quoted
7118 section name. Don't crash on invalid strings.
7119 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

7231 sy_resolved and sy_resolving single bit fields.
7232 * symbols.c (symbol_new): Don't initialize sy_forward field.

8433 lines; I don't think that can be done portably.
8434 * config/tc-mips.c (macro): Use $AT if target register is zero in
8435 load instruction, which it can be for a floating point load.

8509 prototypes for all static functions. Moved existing minimal
8510 debugging format support info #ifndef OBJ_ECOFF blocks.

8559 * make-gas.com: Find obstack.obj if it's not in the current
8561 * read.c (s_ignore): Don't declare is_end_of_line. It's
8562 redundant, and triggers a VMS gcc compiler bug.
8564 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
8565 current segment as an argument. (Ignored in all cases but VMS.)
8566 All callers and definitions changed.

8590 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
8593 * configure.in: mips-bsd configuration was missing format spec.
8596 * Makefile.in (Makefile): Depends on configure.in.
8598 * config/tc-mips.c (append_insn): Don't check for alignment of
8599 frag in memory; alignment of instructions in section is a separate

8619 * config/tc-sparc.c (s_xword): Now call big_cons, so large
8620 constants are accepted, but symbolic values are not. GCC will not
8621 generate the latter currently.
8623 * frags.c (frag_init): New function.
8624 (zero_address_frag, bss_address_frag): Now initialized at run
8626 * as.c (main): Call frag_init.

8894 logical end-of-line character, use the newline case.
8895 From Eric Youngdale:
8896 (operand): Set X_add_number field for floating-point numbers.
8897 (operand): Treat zero byte as end-of-operand.
8899 * configure.in (per-target): Look for with_bfd_assembler option.
8900 For now, only accept "no", until the merge is done.
8902 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
8903 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
8904 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
8905 * read.c: Finish conversion to S_* macros in the VMS only
8906 parts of the program. Add "const" modifier to hex_value.
8907 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
8909 * expr.c: Add "const" modifier to hex_value.
8910 * symbols.c: Finish conversion to S_* macros in the VMS only
8911 parts of the program. Add "const" modifier to
8912 md_[long,short]_jump_size. Remove declaration of const_flag
8913 (which will be declared in obj-vms.h).
8914 * write.c: Add "const" modifier to md_[long,short]_jump_size.
8915 Fix arguments to VMS_write_object_file.
8916 * config-gas.com: New file. Script for VMS systems to set up the
8917 configuration to build gas for VMS, and create config.status.
8918 * make-gas.com: Redone to work with new scheme.
8919 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
8921 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
8922 will swap bytes if needed on a big endian system. Use throughout
8924 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
8925 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
8926 types of malformed stabs. Change parsing algorithm so that we are
8927 more certain of having all of the information that we need on hand.
8928 * obj-vms.c (final_forward_reference): New function, used to help
8929 resolve the data types of as many struct elements as possible
8930 when some part of the struct is not fully defined by the compiler.
8931 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
8933 * obj-vms.c (VMS_write_object_file): Define all vtable psects
8934 as symbols as well in the object file. Look for external functions
8935 that start with "__vt.", and turn them into variables, since the
8936 g++ compiler is incapable of doing this.
8937 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8939 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8940 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8941 have the name of the source file yet.
8942 * config/ho-vms.h: define HO_VMS, not HO_VAX.
8944 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
8946 * read.c (s_data): Always use "data_section", since it'll map to
8947 SEG_DATA or SEG_E1 if needed.
8948 (s_lcomm): Likewise with bss_section.
8949 (s_fill): Use memset, not bzero.
8951 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
8953 * read.c: Deleted some code under "#ifdef DONTDEF" that was for
8954 handling GDB symbol table data.

8967 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
8968 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
8969 (segment_name) If BFD_ASSEMBLER, look up BFD section name;
8970 otherwise, use seg_name array.
8971 (seg_name): Declare only if not BFD_ASSEMBLER.
8972 (section_alignment): Declare only if not BFD_ASSEMBLER.
8973 (big_section, reg_section, pass1_section, diff_section,
8974 absent_section, text_section, data_section, bss_section): If
8975 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8976 mapping to segT enum values.
8977 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8978 if these are used or defined, if BFD_ASSEMBLER.
8979 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8980 subseg_new split into two functions.
8981 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8983 * as.h (volatile): Don't define if already defined.
8984 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8986 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8987 declare with format attribute for -Wformat checking.
8989 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8991 * app.c, config/tc-*.c: Don't include read.h, since it is already
8994 * These are based on patches from Minh Tran-le
8995 <mtranle@paris.intellicorp.com>.
8996 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8997 obj_format coffbfd and gas_target i386coff for target.
8998 (i[34]86-*-isc*): New host (uses sysv).
8999 * config/i386aix.mt: Removed (no longer used).
9000 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
9002 (LDFLAGS): Added, defined as -shlib.
9003 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
9004 * config/te-sco386.h (LOCAL_LABEL): Don't define.
9005 (DOT_LABEL_PREFIX): Define.
9006 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
9007 name rather than L0\001.
9008 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
9010 * symbols.c, symbols.h (local_bss_counter): Removed.
9011 * write.c (write_object_file): bss no longer uses
9012 local_bss_counter. Pass correct data and bss size to
9013 VMS_write_object_file.

9018 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
9019 (size_section): Restored sanity check.
9020 (do_relocs_for): Base section address on s_paddr rather than
9021 computing it. Adjust a29k R_IHIHALF special case to account for
9022 section paddr (used to require paddr to be zero). If there are no
9023 reclos, set s_relptr to 0. Set relocation size in object_headers.
9024 (fill_section): Always set s_vaddr here, removing
9025 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
9026 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
9027 Set STYP_INFO for .comment.
9028 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
9029 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

9031 H_{SET,GET}_* macros.
9032 (do_linenos_for): Set lineno size in object_headers.
9033 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
9034 set s_vaddr here. If string_byte_count remains 4, set it back to
9035 0, and only write strings out if there are some. Call
9036 fill_section before do_relocs_for and do_linenos_for.
9037 (obj_coff_section): Handle optional quoted second argument giving
9038 section characteristics.
9039 (obj_coff_bss): Added to handle .bss.
9040 (obj_coff_ident): Added to handle .ident (puts string in .comment

9043 (fixup_mdeps): Change to segment. Call frag_wane after
9045 (fixup_segment): Explicitly check S_IS_COMMON before making 386
9046 adjustment (already happened only for common symbols, but this is
9048 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

9060 (do_scrub_next_char): For \", return " not '.
9061 (symbol_chars): Now const.
9063 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
9064 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
9066 * config/obj-coff.h: Don't use #elif.
9068 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
9069 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

9093 SEG_BSS, fill with NOP_OPCODE.
9094 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
9095 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
9096 using ZERO_BASED_SEGMENTS.
9097 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
9098 never set segment address for SEG_E2 (.bss) and don't write out
9099 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
9100 (obj_coff_endef): Don't merge labels or symbols awaiting forward
9101 definitions, and don't merge tags with non-tags. Check for .bf
9102 rather than just checking whether the second character is b and
9103 the third character is f.
9104 (obj_coff_val): gcc can generate values which we don't handle
9105 correctly; discard information for now, since it only affects the
9106 debugging information.
9107 (tag_find_or_name): Don't insert tags in the symbol table.
9108 (yank_symbols): Don't merge labels.
9109 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

9366 Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9368 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
9369 * tc-z8k.c: lots of bug fixes
9371 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
9373 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
9374 #elif, since it is not supported by old compilers.
9375 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
9376 couple of expressions in tc-m68k.c.
9378 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9380 * read.c (cons): If NO_RELOC is defined, use it.
9382 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
9384 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
9386 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
9387 local labels to start with a .) and set REGISTER_PREFIX to %.
9388 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
9390 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

9401 * listing.c (debugging_pseudo): Add stabs and stabn as things to
9404 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
9406 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
9407 sections starting from zero, rather than making them consecutive.
9408 This makes subsequent reloc calculations easier, esp if the object
9409 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
9410 allocate lcomm in .data rather than in .bss. It seems that some
9411 tools can't cope with a non-zero sized bss before linkage.
9413 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9415 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
9416 throughout. That enum no longer means what we thought it meant.

9419 "-mno-688[58]1" options.
9421 * tc-m68k.c: Added CPU32 support.

9434 * Makefile.in (install): if $(tooldir) exists, install as in
9437 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
9439 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
9440 .word is < -32768 or > 32767. The -J flag causes the error to be
9441 ignored. This is to catch over-sized switches generated by gcc on
9442 systems which don't support the broken .word hack.
9443 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
9444 write.c (fixup_segment): check for signed .word overflow if
9445 WARN_SIGNED_OVERFLOW_WORD.
9447 * write.c (fixup_segment): fixed missing parens in expression
9448 checking for byte or word overflow.
9450 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
9451 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
9452 WARN_SIGNED_OVERFLOW_WORD.

9462 * tc-i386.h : new coff defines
9464 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
9466 * input-scrub.c (input_scrub_push): call input_file_begin, not
9468 messages.c (as_perror): print ": " between the passed in error and
9469 the strerror, like perror does.
9471 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
9473 * Makefile.in: use gas_target instead of modifying target_cpu.
9474 From Steve Chamberlain:
9475 Makefile.in: Handle m68*-*-coff*.
9476 read.c, read.h: add mult argument to s_space
9478 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
9479 Motorola and MIT syntax; gas can now assemble either type of
9481 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

9487 (write_object_file) call fixup_mdeps
9488 (fixup_segment) set fx_subsy to 0.
9489 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
9491 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
9494 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9496 * Makefile.in (LIBS): Include opcode library.

9518 tc-i960.c (md_ri_to_chars): Always output bout object file in
9519 little endian byte order (used to use endianness of host).
9521 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9523 * config/tc-m68k.c (init_table): Now const. Always include 68851
9524 data, so that "bc" is available to 68040 cache instructions.
9525 Added "tt0", "tt1", and 68ec030 variants.
9526 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9527 (enum _register): Added TT0, TT1.
9528 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9529 line number correctly in "internal error" messages. Don't print
9530 architecture-mismatch message for operand errors.
9532 From Colin Smith (colin@wrs.com):
9533 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
9534 than install_operand.

9555 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9556 has already been formatted (but may still contain %-characters).
9559 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
9561 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
9562 written with indirection on the last two operands, which can be
9563 either data or address registers. Added a new operand type 'r'
9564 which accepts either register type. Added '(' to notend stuff in
9565 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

9855 * expr.c: remove limitation that local_labels_dollar or
9856 local_labels_fb must be < 10.
9858 * symbols.c: remove local_labels_dollar, replace with a function
9859 interface for a sparse array. All users adjusted.
9861 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
9863 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9865 * doc/Makefile.in: commented out line for building as-all.texinfo.
9868 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
9870 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
9872 * Makefile.in: added check target.
9874 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9876 * Makefile.in: added tooldir and program_prefix.
9878 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
9880 * write.{c,h} (fix_new): Make these declarations consistent.
9882 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
9884 * Makefile.in (strerror.o): Add rule so that broken Sun make can
9887 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
9889 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
9891 * expr.c (operand): if can't work out what sort of operand it is,
9892 then look through FLT_CHARS for a hint.
9894 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
9896 * Makefile.in, configure.in: removed traces of namesubdir,
9897 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9898 copyrights to '92, changed some from Cygnus to FSF.
9900 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
9901 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9902 copyrights to '92, changed some from Cygnus to FSF.
9904 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9906 * expr.c: If an expression is single comma, then return with
9907 SEG_ABSENT rather than an error - since the sparc front end does
9908 really strange things with things like fbge,a
9910 * as.h: include bfd.h if using many sections
9911 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
9912 local labels didn't work.
9913 * listing.c (list_symbol_table): don't core dump when there's no
9915 * write.c, write.h: call fix_new with the right number of args on
9917 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
9920 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9922 * app.c: MRI compatibility - allow single quote to start a string.
9923 * as.c: fix typo recently introduced.
9924 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9925 * expr.c: Much rewriting, to accomodate MRI syntax for
9926 expressions. Also easier to read now.
9927 * listing.c: Put back defuns
9928 * read.c: modified to accept MRI syntax, put back listing pseudo
9929 ops so that an assembler built with NO_LISTING ignores list ops
9931 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9932 machine is a SPARC or a 29K.
9933 * config/obj-aout.c: added s_sect pseudo op
9934 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9935 fill in the timestamp.
9936 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9937 anymore, define all the relocs which the tc-<x> bit will use so we
9938 can translate from them to the coff types.
9939 * config/tc-a29k.c: reloc_type isn't ane enum any more
9940 * config/tc-m68k.c: Added NO_RELOC definition.
9942 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9944 * Makefile.in: put header files before C source for TAGS; remove
9945 references to non-existent syscalls.h.
9947 * read.c, write.c subsegs.c: back out the .bss changes.
9949 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9951 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9955 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9957 * symbols.c (local_label_name): symbols now start with ^A.
9959 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9960 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9961 generate these sections. .align: will use NOP_OPCODE or 0
9962 for padding. This is just for being nice to the
9965 * expr.c (operand): changed to generate local label "\001L0"
9966 starting with a ^A so that it is recognized as a local label.
9968 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9970 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9971 i/o opcodes - inb, inw, outb and outw. string manipulation with
9972 att syntax - scmp, slod, smov, ssca, ssto.
9974 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9975 to just after .file .
9977 In obj_crawl_symbol_chain() where it tries to put the external
9978 symbols apart, with the condition:
9979 (!S_IS_DEFINED(symbolP) &&
9980 !S_IS_DEBUG(symbolP) &&
9981 !SF_GET_STATICS(symbolP))
9982 it was moving too many symbols out. So I switch it back to the
9984 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9986 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9987 so that we don't use the F_RELFLG which make the linker complain
9988 that somebody has stripped the relocation info.
9990 Also, the AIX ld program require that the relocation table
9991 is sorted by r_vaddr like the standard ATT assembler does.
9993 [he also changed the sizeof(struct ...)'s into the coff
9994 style FOOSZ macros. I'm not sure this is right, but I can't
9995 remember why. xoxorich.]
9997 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9999 * Makefile.in, configure.in, doc: use the doc. Build it, install
10002 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
10004 * read.c: white space and comments only.
10006 * configure.in: use the new atof-ns32.c for ns32k.
10008 * write.c: comment change only.
10010 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
10011 aren't yet integrated.
10013 * tc-i860.[hc]: blew off the dust. Something must still be done
10014 about conflicting relocation types.
10016 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
10019 * tc-i960.c, tc-sparc.c: white space and comments only.
10021 * tc-a29k.h: delete duplicate macro definition.
10023 * new file atof-ns32k.c copied from hack's last unreleased gas.
10025 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
10027 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
10030 * nearly everything. flush ChangeLog, package as gas-1.92.1.
10031 ChangeLog's prior to this are sketchy at best. I have logs.
10032 They just aren't ChangeLogs.
