1505 Add a space after "pc-relative" in the error message.
1506 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
1507 BFD_RELOC_386_GOTOFF relocs.

1549 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1551 * configure.in: Set bfd_gas for all sparc targets in one place,
1552 instead of separately for each. Correctly handle user-supplied
1553 "--enable-bfd-gas" option.
1555 * gdbinit.in: Move "break abort" to end, in case gdb complains.

1565 (indent_level): No longer static.
1566 (print_symbol_value_1): Don't print frag address if it matches

1570 (print_expr_1): Fix whitespace before printing X_add_number.
1572 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1573 not symbol_new, for symbols holding expression values.
1574 * expr.h (make_expr_symbol): Move declaration here.
1575 * write.c (fix_new_exp): Handle O_add by creating an
1576 expression-valued symbol, and calling fix_new_exp recursively.
1577 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1578 undefined symbol and a constant, fold the constant into the fixup,
1579 and refer to the undefined symbol directly. Then process the
1580 fixup again from scratch.
1581 (write_object_file): Before calling adjust_reloc_syms, make a pass
1582 through the symbol list trying to resolve values.
1584 * write.c (print_fixup): New routine, for debugging.
1585 (write_relocs): Call bfd_install_relocation. Deleted various
1586 hacks for working around problems with bfd_perform_relocation.
1588 * Makefile.in (VERSION): Update to 2.4.90.
1590 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

1603 * write.c (write_relocs): Add file name and line number to
1604 as_fatal calls. Handle bfd_reloc_overflow case specifically when

1609 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1610 here. Use them for deciding which PRINTF*LIKE macro definitions
1612 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
1613 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1614 default definitions matching what we were doing before.
1615 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1616 always use the varargs form if not using stdarg. It's safe to
1617 always use vfprintf, because libiberty will provide it if the
1618 native system doesn't. Also, always make format be const.
1619 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

1634 (listing_newline): Check filename as well as line number when
1635 deciding whether to record it.
1636 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1637 false (if defined) as well as checking for reg_section.
1638 (listing_listing): Iterate fetching lines while line number is too
1639 low, and we haven't run off the end of the input file.
1641 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1643 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

1652 * config/ho-*.h: Now-unused files deleted.
1654 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1655 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1656 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1657 zero. Don't call obj_frob_forward_symbol.

1660 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1662 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1664 (strchr): Don't declare.

1666 md_estimate_size_before_relax, md_ri_to_chars,
1667 md_create_short_jump, md_create_long_jump.
1668 (brtab_emit): Use data_section, not SEG_DATA.
1670 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1672 * config/vms-conf.h: new file, manually derived from conf.in.
1673 * config-gas.com: use it, and eliminate obsolete "host.h".

1682 (ppc_es): Clear ppc_current_block.
1683 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1684 from the csect of the enclosing block.
1686 * config/tc-mips.c (insns_since_cache_access): Remove.
1687 (append_insn): Remove setting of insns_since_cache_access, and
1688 special 4600 handling; it turns out not to be required.
1690 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1692 * config/tc-mips.c (md_shortopts): Remove E.
1693 (md_longopts): Add EB and EL.
1694 (md_parse_option): Handle -EB and -EL as separate options, rather
1695 than as a single -E option with an argument.

1704 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1706 * configure.in: Test for remove, not delete. Fix cross-assembler
1708 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to

1712 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1713 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1714 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.

1718 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1719 many others): new macros; values obtained from "DSTRECRDS.SDL".
1720 * config/obj-vms.h (various): use them.
1721 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1722 representation (only enum bitfields can avoid being bitstrings).
1723 (bitfield_suffix, setup_basic_type): new routines.
1724 (VMS_typedef_parse): use them. Now recognize bitfields of all
1725 integral types, not just type `int'. Caveat: the representation
1726 used for bitfields still does not work for objects placed in
1727 registers, and gcc's optimizer sometimes puts small structs there.
1729 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1731 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1732 bit from const_flag.
1733 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.

1738 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1739 (vms_check_for_special_label): new routine (tc_frob_label).
1740 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1741 and `gcc2_compiled.' labels; they won't reach here any more.
1742 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1743 double', use `vax_g_doubles' flag to select type of double.
1744 (VMS_write_object_file) [traceback setup]: don't pass symbols
1745 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1746 and TBT_Routine_End functions.

1750 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1751 S_GET_VALUE() to avoid many repeated function calls.
1752 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1753 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1754 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1755 be obsolete; gcc does it automatically for vms target. It's
1756 also misnamed, because it is for the "VAX C" run-time library,
1757 not the newer "DEC C" one which has much different startup code.]
1758 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1759 `S_GET_xxx(symbol) = new_value'.
1761 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1763 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1764 not &bfd_abs_section.
1766 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1768 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1770 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1772 * expr.c (expr): Don't reduce the difference of two symbols in the
1773 same frag if the symbols are not in normal sections.
1775 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1776 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1777 (obj_attach_unwind_info): Do not define. Not needed anymore.
1778 * config/tc-hppa.c: Delete whitespace at EOL.
1779 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1780 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1781 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1782 fixups, store 32bits of unwind information in the fx_addnumber
1784 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
1785 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
1786 pointer to 32 bits of unwind info.
1787 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
1788 pointer to the dummy symbol; set the addend field to fx_addnumber.
1789 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
1790 rather than &bfd_XXX_section.
1792 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1794 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
1795 value by one; discard adjustments previously being made. From
1798 VMS- and Vax-related changes from Pat Rankin:
1799 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
1800 * vmsconf.sh: no longer have make-gas.com echo text about needing
1801 to modify the gcc-vms driver when intending to use with gcc 1.x.
1802 * as.c (parse_options): suppress 'v' from std_short_options and
1803 eliminate VMS-specific conditional initialization;
1804 [default case]: check for '-v' if md_parse_options doesn't recognize

1808 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
1809 for O_big literal operands (double floats and long long ints);
1810 [VMS, md_shortopts]: add second colon after 'v';
1811 (md_parse_options) [VMS, case 'v']: check for argument, so
1812 caller can handle `-v' w/o arg.

1857 Rewrite handling of program_transform_name.
1859 * configure.in: Test for functions unlink and delete.

1865 * .gdbinit: Deleted.
1866 * aclocal.m4 (GAS_GDBINIT): Deleted.

1870 to ensure that older versions of autoconf aren't used.
1871 * Makefile.in: Added @configure_input@ line.
1872 (configure): Deleted rule.
1874 Tue Sep 13 12:08:20 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1876 * config/obj-coff.c (fixup_segment): After handling the difference
1877 of two symbols from the same segment, set fx_subsy to NULL, to

3300 * expr.c (operand): Try to parse "0f" and "0b" sequences as
3301 floating point and binary numbers respectively; if it doesn't
3302 work, treat them as local labels.
3304 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
3305 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
3307 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
3309 * vmsconf.sh: In generated file, get ".obj" suffix right, build
3310 source files from other directories into objects in the current
3311 directory, and specify PSECT attributes explicitly to linker.
3312 Also added missing label.
3313 * Makefile.in (stamp-mk.com): Reference new variable

3329 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
3330 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
3331 argument, the reloc type.
3332 (load_register): Pass reloc type to macro_build for 'u'.
3333 (macro): Likewise. For M_LA_AB permit a difference expression
3334 when generating embedded PIC code between an arbitrary symbol and
3335 a symbol in the .text section.
3336 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
3337 BFD_RELOC_PCREL_LO16 to be emitted.

3345 * subsegs.c (subsegs_begin): Call memset with args in the correct
3347 (subseg_get): Clear newly allocated seginfo, set its pointer slots
3348 to NULL instead of 0.

3352 * config/tc-hppa.c (pa_procend): Handle case where label was
3353 defined after the .proc directive.
3355 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
3356 procend for a procedure without a name.

3377 (hppa_tc_symbol): Likewise.
3379 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
3380 elf_tc_make_sections stuff. It was there to support PA braindamage
3381 which has been fixed, and in the case of elf_tc_make_sections is
3382 redundant with elf_tc_final_processing.
3384 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3386 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

3402 don't spew remainder of input file in error message.
3403 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
3404 message with reloc type and try to process remainder of file.
3406 * doc/Makefile.in (install-info-as, install-info-gasp): New
3407 targets, now explicitly checking $(srcdir) for info files.
3408 (install-info): Depend on both of them; do nothing more.

3412 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
3414 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3416 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
3417 flag rather than signedp field. Only permit extended range if
3418 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
3419 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
3421 * config/tc-ppc.c (ppc_size): New static variable.
3422 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
3423 (md_begin): If an instruction has a size specific flag set, only
3424 add it if we are assembling that size.
3426 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3428 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
3429 cross section PC relative relocs right for COFF and ELF.
3431 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3433 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
3434 (OBJ_PROCESS_STAB): Don't define.
3436 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3438 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
3439 the type of symbol set symbols which happen to be in the absolute
3440 or undefined section.
3442 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
3444 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
3445 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
3446 and -many (all architectures).
3448 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3450 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
3451 involving a function symbol which is not a plabel to zero.
3452 (md_apply_fix): Never pass a function symbol to field_adjust.
3454 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3456 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
3457 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
3459 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
3460 branch with an instruction that uses $at, in case the branch is
3462 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
3463 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
3464 to make it pcrel_offset.
3465 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
3466 reloc->address; another gruesome hack to get gas reloc handling to
3469 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3471 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
3474 (emit_insn): New function.
3475 (md_assemble): Call it.
3476 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
3478 (lituse_pending): New variable. Set by anything that generates a
3479 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
3480 tested by code that might want to emit a LITUSE reloc.
3481 (emit_unaligned_io): New function. Currently calls md_assemble,
3482 but it should eventually be converted to generate the insn itself
3483 and call emit_insn directly.
3484 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
3485 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
3486 emit_bis_r): Likewise.
3487 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
3488 (alpha_ip, label get_macro): Don't emit the final instruction if
3490 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
3491 unaligned memory access macros.
3492 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
3493 the value can't be resolved.
3495 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3497 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
3498 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
3499 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
3501 (mips_force_relocation): New function.
3502 (md_apply_fix): Set fixP->fx_done appropriately.
3503 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

3511 * config/tc-mips.c (enum mips_pic_level): New enum.
3512 (mips_pic): Change from int to enum mips_pic_level. Change all
3513 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3514 (load_address): Handle EMBEDDED_PIC.
3515 (macro): Handle EMBEDDED_PIC in all PIC cases.
3516 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3517 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3518 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3519 works). Do not permit -G with SVR4_PIC.
3520 (s_abicalls): Warn if -G was used, and force -G 0.
3521 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3522 anything but a.out, not just for ELF. For ECOFF, don't generate a
3523 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3525 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3527 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3529 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3530 parameters to avoid losing when compiling with HP CC.
3531 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3533 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3535 * Makefile.in (config-stamp): If `defs' is defined, emit a
3536 preprocessor directive to create a macro named by this value into
3537 config.new; don't explicitly go for BFD_ASSEMBLER.
3538 * configure.in: Define `defs', not `BFDDEF'. Set it to
3539 MANY_SEGMENTS for any obj-coffbfd target.
3540 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3541 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3543 (LOCAL_LOADLIBES): Deleted.
3544 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3545 * config/m88kcoff.mt (TDEFINES): Ditto.
3546 * config/ebmon29k.mt: Deleted.
3547 * config/h8300hds.mt: Deleted.
3548 * config/ic960coff.mt: Deleted.
3549 * config/sparc.mt: Deleted.
3550 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3551 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3552 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3553 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

3571 bfd_set_symtab is called.
3572 (dump_section_relocs): Note whether a symbol is a section symbol
3574 (adjust_reloc_syms): For now, always supply an absolute symbol for
3575 fixups without symbols but not yet `done'. Use section_symbol to
3576 get the symbol, instead of going directly for abs_symbol.
3577 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3578 reloc is not a section symbol and is not in the symbol table.
3579 (set_symtab): New function, broken out from write_object_file.
3580 Counts symbol table instead of relying on an earlier count.
3581 (write_object_file): Call set_symtab, but do it after potentially
3582 invoking the *_frob_file macros. Don't bother counting symbols.
3583 Call symbol_remove, instead of expanding it in place. Moved the
3584 conditionalized `object_file_size' declaration down to
3585 conditionalized block where it's used. When using the absolute
3586 symbol for a fixup without a symbol, set sy_used_in_reloc.
3587 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3588 the correct symbol for the absolute section.
3590 * subsegs.c (section_symbol): Use symbol_new instead of
3591 symbol_make, since we may want it to go into the symbol table.
3592 Make the new symbol have internal linkage. If
3593 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3594 symbol with the newly created GAS symbol.
3595 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3596 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
3598 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
3600 * config/tc-sparc.c: Include subsegs.h.
3601 (in_signed_range): New function.
3603 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3604 (sparc_ip, label "immediate"): Reject constants for pcrel
3605 instructions only if the relocation type indicates a "call"
3606 instruction and the offset is within range of a "jmpl %g0". If
3607 it's not in range, use the absolute section symbol plus an offset.
3608 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3610 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3612 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3615 * configure.in: Eliminated all targets using obj-coff but not
3616 defining BFD_ASSEMBLER; I think all such targets that are
3617 supported will be matched by real CPU-OS combinations earlier in
3619 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
3620 some comments about the dpx2 configuration, but left it disabled,
3621 since it couldn't be reached before.
3622 (target a29k-amd-ebmonold): Deleted.
3624 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3632 the 'j' operand if there are no further alternatives for this
3635 * config/obj-coffbfd.c (adjust_stab_section): Initialize
3636 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
3637 is not SEG_UNKNOWN rather than checking whether it is >= 0.
3639 * config/tc-mips.c (mips_align): Take new argument, label, and use
3640 it instead of global insn_label.
3641 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
3642 call to mips_emit_delay and pass it to mips_align.
3644 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3646 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
3648 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
3649 argument to a .callinfo directive. Don't loop forever on errors.
3651 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
3652 use pre-defined registers as arguments.

3656 * write.c (write_object_file): Check both S_IS_LOCAL and
3657 S_IS_EXTERNAL when deciding whether to discard a symbol.
3659 * config-gas.com: Scan Makefile.in, not version.c, for current
3660 version number. Delete all versions of temp files when finished
3661 with them. Create config.h.
3663 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
3664 values to reduce number of lookups with S_GET_VALUE. Skip debug
3665 symbols to avoid "a really nasty bug". (From Holger Teutsch,
3666 holger@botbso.rhein-main.de.)
3667 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
3668 field. (Also from Holger Teutsch.) Watch for a would-be register
3669 mask that spans frags.
3671 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
3672 this_base, not line_base. (Patch from Andreas Arens,
3673 ari@obelix.av.rwth-aachen.de.)
3675 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
3676 look local if they're exported or undefined. Used to be done for
3679 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
3680 Get it from the looked-up symbol, instead of using the string from
3681 the input stream, which is no longer null-terminated.
3682 (LEX_PCT): New macro, defaults to 0.
3683 (lex_type): Use it for `%'.
3685 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
3686 (vip_op): Now static, and returns void. Callers changed. Added
3688 (vip): Ditto. Call as_fatal directly if a program bug is
3690 (op_hash): Let default initialization suffice.

3723 (NO_RELOC): Undefine before defining as part of enum reloc_type.
3725 * config/tc-alpha.c: Add comment questioning need for all the
3726 characters in FLT_CHARS.

3730 * config/obj-ecoff.c (ecoff_frob_file): Set strict order for
3731 sections with recognized names, before computing VMA values.

3735 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
3736 0xffff for 'j' to be compatible with MIPS assembler. These
3737 numbers are actually treated as negative.
3739 Thu Mar 10 13:36:29 1994 Doug Evans (dje@canuck.cygnus.com)
3741 * config/tc-sparc.h (LOCAL_LABEL): Local labels are .Lfoo.

3746 (obj_coff_section): Declare.
3747 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
3748 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

5692 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
5693 the table, require that the one without bit 0x1000000 set come
5694 first. Require further that it be case 'b' or 'P'. The a29k
5695 opcode table already meets these constraints.
5696 (machine_ip): When handling case 'i' or 'A', make sure that the
5697 appropriate opcode really exists by looking at the next entry in

5752 * write.c (write_relocs): For relocs that are pc_relative and
5753 pcrel_offset and not partial_inplace, adjust reloc->addend to

5806 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
5808 * configure.in: Set bfd_gas for all sparc targets. Added facility
5809 for keeping or rejecting configurations still under development;
5810 default is to assume production environment, and reject configs
5811 still being worked on. Mark Elf configurations (except sparc and
5812 i386) as developmental. Deleted cases matching some generic names
5813 in favor of more specific names. (E.g., when we get Alpha

5830 through inclusion of tc-hppa.h. Delete all forward declarations
5831 for functions only used within tc-hppa.c, likewise for structures,
5832 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
5833 conditional code in a few small places.
5835 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
5836 structures, global variables, forward declarations together.

5838 conditional code -- try to group conditional code together
5839 into a few places. Make all functions and variables which
5840 are only used within tc-hppa.c static. PARAMize all functions.
5841 Add comments to functions. Delete unused functions, variables,
5842 #defines, etc. Delete unused members within structures. Delete
5843 ldil;ble hacks -- it is believed they were installed to work
5844 around old gas bugs. Avoid using mixed case for local
5845 functions, variables, and structures. Fix formatting problems
5846 not found by GNU-indent. Add FIXME notices for things which
5847 should be worked on the near future. Delete lots of old
5848 useless (1.36 PA-SOM) code.
5850 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
5851 field of the fixS structure. Needed to build unwind
5852 descriptors correctly.

5876 * config/tc-hppa.c: (md_section_align): Align all sections to
5877 a multiple of the section alignment rather than always a
5880 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
5881 bits are zero (eg they specify no relocations), then do not even
5882 bother adding their entries to thesymextn section.

5923 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
5924 call strchr for each character to see if it is a special char,
5925 instead add a second loop over special_chars. Set alignment
5926 of text, data and bss sections to 4.
5927 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5929 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5930 ELF, since the ELF object format does not have these type of
5931 relocations. Change the abort into as as_bad and return
5932 BFD_RELOC_NONE to silence compiler warnings.
5933 (md_assemble): Keep track of the instruction size. Allow white
5934 space between the $ and the constant for compatibility with older
5935 gases and other assemblers.
5936 (i386_operand): Skip spaces between $ and expression.

6982 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
6983 *-*-solaris case, and move to before *-sysv* case that wants to
6984 set obj_format to coff.

7010 * Extensive changes to permit symbols to contain any expression
7011 type and to delay the computation of the expression until the
7012 value is actually needed. This permits setting symbols to values
7013 calculated based on object code size. Expressions were changed to
7014 no longer be in a section, to stop the overloading of segment and
7015 expression type that previously occurred.
7017 * as.c (big_section, pass1_section, diff_section, absent_section):

7103 (previous_section, previous_subsection): New vars.
7104 (obj_elf_section): Save current place in case DWARF code wants us
7105 to pop back to it. Handle unquoted section name as well as quoted
7106 section name. Don't crash on invalid strings.
7107 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
7110 * config/obj-elf.h: Don't include struc-symbol.h.

7219 sy_resolved and sy_resolving single bit fields.
7220 * symbols.c (symbol_new): Don't initialize sy_forward field.

8421 lines; I don't think that can be done portably.
8422 * config/tc-mips.c (macro): Use $AT if target register is zero in
8423 load instruction, which it can be for a floating point load.

8497 prototypes for all static functions. Moved existing minimal
8498 debugging format support info #ifndef OBJ_ECOFF blocks.

8547 * make-gas.com: Find obstack.obj if it's not in the current
8549 * read.c (s_ignore): Don't declare is_end_of_line. It's
8550 redundant, and triggers a VMS gcc compiler bug.
8552 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
8553 current segment as an argument. (Ignored in all cases but VMS.)
8554 All callers and definitions changed.

8578 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
8581 * configure.in: mips-bsd configuration was missing format spec.
8584 * Makefile.in (Makefile): Depends on configure.in.
8586 * config/tc-mips.c (append_insn): Don't check for alignment of
8587 frag in memory; alignment of instructions in section is a separate

8608 constants are accepted, but symbolic values are not. GCC will not
8609 generate the latter currently.
8611 * frags.c (frag_init): New function.
8612 (zero_address_frag, bss_address_frag): Now initialized at run
8614 * as.c (main): Call frag_init.

8890 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
8891 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
8892 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
8893 * read.c: Finish conversion to S_* macros in the VMS only
8894 parts of the program. Add "const" modifier to hex_value.
8895 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
8897 * expr.c: Add "const" modifier to hex_value.
8898 * symbols.c: Finish conversion to S_* macros in the VMS only
8899 parts of the program. Add "const" modifier to
8900 md_[long,short]_jump_size. Remove declaration of const_flag
8901 (which will be declared in obj-vms.h).
8902 * write.c: Add "const" modifier to md_[long,short]_jump_size.
8903 Fix arguments to VMS_write_object_file.
8904 * config-gas.com: New file. Script for VMS systems to set up the
8905 configuration to build gas for VMS, and create config.status.
8906 * make-gas.com: Redone to work with new scheme.
8907 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
8909 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
8910 will swap bytes if needed on a big endian system. Use throughout
8912 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
8913 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
8914 types of malformed stabs. Change parsing algorithm so that we are
8915 more certain of having all of the information that we need on hand.
8916 * obj-vms.c (final_forward_reference): New function, used to help
8917 resolve the data types of as many struct elements as possible
8918 when some part of the struct is not fully defined by the compiler.
8919 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
8921 * obj-vms.c (VMS_write_object_file): Define all vtable psects
8922 as symbols as well in the object file. Look for external functions
8923 that start with "__vt.", and turn them into variables, since the
8924 g++ compiler is incapable of doing this.
8925 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8927 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8928 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8929 have the name of the source file yet.
8930 * config/ho-vms.h: define HO_VMS, not HO_VAX.
8932 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
8934 * read.c (s_data): Always use "data_section", since it'll map to
8935 SEG_DATA or SEG_E1 if needed.
8936 (s_lcomm): Likewise with bss_section.
8937 (s_fill): Use memset, not bzero.
8939 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
8941 * read.c: Deleted some code under "#ifdef DONTDEF" that was for
8942 handling GDB symbol table data.

8955 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
8956 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

8960 (section_alignment): Declare only if not BFD_ASSEMBLER.
8961 (big_section, reg_section, pass1_section, diff_section,
8962 absent_section, text_section, data_section, bss_section): If
8963 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8964 mapping to segT enum values.
8965 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8966 if these are used or defined, if BFD_ASSEMBLER.
8967 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8968 subseg_new split into two functions.
8969 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8971 * as.h (volatile): Don't define if already defined.
8972 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8974 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8975 declare with format attribute for -Wformat checking.
8977 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8979 * app.c, config/tc-*.c: Don't include read.h, since it is already
8982 * These are based on patches from Minh Tran-le
8983 <mtranle@paris.intellicorp.com>.
8984 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8985 obj_format coffbfd and gas_target i386coff for target.
8986 (i[34]86-*-isc*): New host (uses sysv).
8987 * config/i386aix.mt: Removed (no longer used).
8988 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8990 (LDFLAGS): Added, defined as -shlib.
8991 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8992 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8993 (DOT_LABEL_PREFIX): Define.
8994 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8995 name rather than L0\001.
8996 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8998 * symbols.c, symbols.h (local_bss_counter): Removed.
8999 * write.c (write_object_file): bss no longer uses
9000 local_bss_counter. Pass correct data and bss size to
9001 VMS_write_object_file.

9006 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
9007 (size_section): Restored sanity check.
9008 (do_relocs_for): Base section address on s_paddr rather than
9009 computing it. Adjust a29k R_IHIHALF special case to account for
9010 section paddr (used to require paddr to be zero). If there are no
9011 reclos, set s_relptr to 0. Set relocation size in object_headers.
9012 (fill_section): Always set s_vaddr here, removing
9013 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
9014 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
9015 Set STYP_INFO for .comment.
9016 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
9017 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

9019 H_{SET,GET}_* macros.
9020 (do_linenos_for): Set lineno size in object_headers.
9021 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
9022 set s_vaddr here. If string_byte_count remains 4, set it back to
9023 0, and only write strings out if there are some. Call
9024 fill_section before do_relocs_for and do_linenos_for.
9025 (obj_coff_section): Handle optional quoted second argument giving
9026 section characteristics.
9027 (obj_coff_bss): Added to handle .bss.
9028 (obj_coff_ident): Added to handle .ident (puts string in .comment

9031 (fixup_mdeps): Change to segment. Call frag_wane after
9033 (fixup_segment): Explicitly check S_IS_COMMON before making 386
9034 adjustment (already happened only for common symbols, but this is
9036 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

9048 (do_scrub_next_char): For \", return " not '.
9049 (symbol_chars): Now const.
9051 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
9052 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
9054 * config/obj-coff.h: Don't use #elif.
9056 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
9057 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

9083 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
9084 using ZERO_BASED_SEGMENTS.
9085 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
9086 never set segment address for SEG_E2 (.bss) and don't write out
9087 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
9088 (obj_coff_endef): Don't merge labels or symbols awaiting forward
9089 definitions, and don't merge tags with non-tags. Check for .bf
9090 rather than just checking whether the second character is b and
9091 the third character is f.
9092 (obj_coff_val): gcc can generate values which we don't handle
9093 correctly; discard information for now, since it only affects the
9094 debugging information.
9095 (tag_find_or_name): Don't insert tags in the symbol table.
9096 (yank_symbols): Don't merge labels.
9097 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

9361 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
9362 #elif, since it is not supported by old compilers.
9363 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
9364 couple of expressions in tc-m68k.c.
9366 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9368 * read.c (cons): If NO_RELOC is defined, use it.
9370 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
9372 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
9374 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
9375 local labels to start with a .) and set REGISTER_PREFIX to %.
9376 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
9378 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

9389 * listing.c (debugging_pseudo): Add stabs and stabn as things to
9392 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
9394 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
9395 sections starting from zero, rather than making them consecutive.
9396 This makes subsequent reloc calculations easier, esp if the object
9397 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
9398 allocate lcomm in .data rather than in .bss. It seems that some
9399 tools can't cope with a non-zero sized bss before linkage.
9401 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9403 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
9404 throughout. That enum no longer means what we thought it meant.

9407 "-mno-688[58]1" options.
9409 * tc-m68k.c: Added CPU32 support.

9422 * Makefile.in (install): if $(tooldir) exists, install as in
9425 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
9427 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
9428 .word is < -32768 or > 32767. The -J flag causes the error to be
9429 ignored. This is to catch over-sized switches generated by gcc on
9430 systems which don't support the broken .word hack.
9431 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
9432 write.c (fixup_segment): check for signed .word overflow if
9433 WARN_SIGNED_OVERFLOW_WORD.
9435 * write.c (fixup_segment): fixed missing parens in expression
9436 checking for byte or word overflow.
9438 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

9450 * tc-i386.h : new coff defines
9452 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
9454 * input-scrub.c (input_scrub_push): call input_file_begin, not
9456 messages.c (as_perror): print ": " between the passed in error and
9457 the strerror, like perror does.
9459 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
9461 * Makefile.in: use gas_target instead of modifying target_cpu.
9462 From Steve Chamberlain:
9463 Makefile.in: Handle m68*-*-coff*.
9464 read.c, read.h: add mult argument to s_space
9466 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
9467 Motorola and MIT syntax; gas can now assemble either type of
9469 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

9475 (write_object_file) call fixup_mdeps
9476 (fixup_segment) set fx_subsy to 0.
9477 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
9479 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
9482 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9484 * Makefile.in (LIBS): Include opcode library.

9509 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9511 * config/tc-m68k.c (init_table): Now const. Always include 68851
9512 data, so that "bc" is available to 68040 cache instructions.
9513 Added "tt0", "tt1", and 68ec030 variants.
9514 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9515 (enum _register): Added TT0, TT1.
9516 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9517 line number correctly in "internal error" messages. Don't print
9518 architecture-mismatch message for operand errors.
9520 From Colin Smith (colin@wrs.com):
9521 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
9522 than install_operand.

9543 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9544 has already been formatted (but may still contain %-characters).
9547 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
9549 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
9550 written with indirection on the last two operands, which can be
9551 either data or address registers. Added a new operand type 'r'
9552 which accepts either register type. Added '(' to notend stuff in
9553 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

9853 * doc/Makefile.in: commented out line for building as-all.texinfo.
9856 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
9858 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
9860 * Makefile.in: added check target.
9862 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9864 * Makefile.in: added tooldir and program_prefix.
9866 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
9868 * write.{c,h} (fix_new): Make these declarations consistent.
9870 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
9872 * Makefile.in (strerror.o): Add rule so that broken Sun make can
9875 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
9877 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
9879 * expr.c (operand): if can't work out what sort of operand it is,
9880 then look through FLT_CHARS for a hint.
9882 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
9884 * Makefile.in, configure.in: removed traces of namesubdir,
9885 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9886 copyrights to '92, changed some from Cygnus to FSF.
9888 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
9889 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9890 copyrights to '92, changed some from Cygnus to FSF.
9892 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9894 * expr.c: If an expression is single comma, then return with
9895 SEG_ABSENT rather than an error - since the sparc front end does
9896 really strange things with things like fbge,a
9898 * as.h: include bfd.h if using many sections
9899 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
9900 local labels didn't work.
9901 * listing.c (list_symbol_table): don't core dump when there's no
9903 * write.c, write.h: call fix_new with the right number of args on
9905 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
9908 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9910 * app.c: MRI compatibility - allow single quote to start a string.
9911 * as.c: fix typo recently introduced.
9912 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9913 * expr.c: Much rewriting, to accomodate MRI syntax for
9914 expressions. Also easier to read now.
9915 * listing.c: Put back defuns
9916 * read.c: modified to accept MRI syntax, put back listing pseudo
9917 ops so that an assembler built with NO_LISTING ignores list ops
9919 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9920 machine is a SPARC or a 29K.
9921 * config/obj-aout.c: added s_sect pseudo op
9922 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9923 fill in the timestamp.
9924 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9925 anymore, define all the relocs which the tc-<x> bit will use so we
9926 can translate from them to the coff types.
9927 * config/tc-a29k.c: reloc_type isn't ane enum any more
9928 * config/tc-m68k.c: Added NO_RELOC definition.
9930 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9932 * Makefile.in: put header files before C source for TAGS; remove
9933 references to non-existent syscalls.h.
9935 * read.c, write.c subsegs.c: back out the .bss changes.
9937 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9939 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9943 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9945 * symbols.c (local_label_name): symbols now start with ^A.
9947 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9948 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9949 generate these sections. .align: will use NOP_OPCODE or 0
9950 for padding. This is just for being nice to the
9953 * expr.c (operand): changed to generate local label "\001L0"
9954 starting with a ^A so that it is recognized as a local label.
9956 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9958 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9959 i/o opcodes - inb, inw, outb and outw. string manipulation with
9960 att syntax - scmp, slod, smov, ssca, ssto.
9962 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9963 to just after .file .
9965 In obj_crawl_symbol_chain() where it tries to put the external
9966 symbols apart, with the condition:
9967 (!S_IS_DEFINED(symbolP) &&
9968 !S_IS_DEBUG(symbolP) &&
9969 !SF_GET_STATICS(symbolP))
9970 it was moving too many symbols out. So I switch it back to the
9972 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9974 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9975 so that we don't use the F_RELFLG which make the linker complain
9976 that somebody has stripped the relocation info.
9978 Also, the AIX ld program require that the relocation table
9979 is sorted by r_vaddr like the standard ATT assembler does.
9981 [he also changed the sizeof(struct ...)'s into the coff
9982 style FOOSZ macros. I'm not sure this is right, but I can't
9983 remember why. xoxorich.]
9985 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9987 * Makefile.in, configure.in, doc: use the doc. Build it, install
9990 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9992 * read.c: white space and comments only.
9994 * configure.in: use the new atof-ns32.c for ns32k.
9996 * write.c: comment change only.
9998 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9999 aren't yet integrated.
10001 * tc-i860.[hc]: blew off the dust. Something must still be done
10002 about conflicting relocation types.
10004 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
10007 * tc-i960.c, tc-sparc.c: white space and comments only.
10009 * tc-a29k.h: delete duplicate macro definition.
10011 * new file atof-ns32k.c copied from hack's last unreleased gas.
10013 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
10015 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
10018 * nearly everything. flush ChangeLog, package as gas-1.92.1.
10019 ChangeLog's prior to this are sketchy at best. I have logs.
10020 They just aren't ChangeLogs.
