509 OPTIONAL_REGISTER_PREFIX if either is already defined.
511 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
513 * configure.in: Set bfd_gas for all sparc targets. Added facility
514 for keeping or rejecting configurations still under development;
515 default is to assume production environment, and reject configs
516 still being worked on. Mark Elf configurations (except sparc and
517 i386) as developmental. Deleted cases matching some generic names
518 in favor of more specific names. (E.g., when we get Alpha
519 support, we'll still only support VMS for Vax.)

533 against placing additional object-file dependent code here. Warn
534 against contaminating all of GAS with the internals of tc-hppa.c
535 through inclusion of tc-hppa.h. Delete all forward declarations
536 for functions only used within tc-hppa.c, likewise for structures,
537 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
538 conditional code in a few small places.
540 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
541 structures, global variables, forward declarations together.
542 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
543 conditional code -- try to group conditional code together
544 into a few places. Make all functions and variables which
545 are only used within tc-hppa.c static. PARAMize all functions.
546 Add comments to functions. Delete unused functions, variables,
547 #defines, etc. Delete unused members within structures. Delete
548 ldil;ble hacks -- it is believed they were installed to work
549 around old gas bugs. Avoid using mixed case for local
550 functions, variables, and structures. Fix formatting problems
551 not found by GNU-indent. Add FIXME notices for things which
552 should be worked on the near future. Delete lots of old
553 useless (1.36 PA-SOM) code.
555 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type

564 * tc-hppa.h (tc_fix_adjustable): New macro. Only accept relocations
565 which do not involve function symbols.
567 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
568 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
570 * config/tc-hppa.c: Likewise.
572 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
573 of elf32_symbol_type.
574 (pa_export_args): Likewise.
575 (elf_hppa_final_processing): Likewise.
576 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed
578 (hppa_tc_make_sections): Do not declare elf_get_symtab_map any
581 * config/tc-hppa.c: (md_section_align): Align all sections to
582 a multiple of the section alignment rather than always a
585 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
586 bits are zero (eg they specify no relocations), then do not even
587 bother adding their entries to thesymextn section.

626 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
628 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
629 ELF, since the ELF object format does not have these type of
630 relocations. Change the abort into as as_bad and return
631 BFD_RELOC_NONE to silence compiler warnings.
632 (md_assemble): Keep track of the instruction size. Allow white
633 space between the $ and the constant for compatibility with older
634 gases and other assemblers.
635 (i386_operand): Skip spaces between $ and expression.
636 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

1696 * Extensive changes to permit symbols to contain any expression
1697 type and to delay the computation of the expression until the
1698 value is actually needed. This permits setting symbols to values
1699 calculated based on object code size. Expressions were changed to
1700 no longer be in a section, to stop the overloading of segment and
1701 expression type that previously occurred.
1703 * as.c (big_section, pass1_section, diff_section, absent_section):
1705 (expr_section): Added (used for dummy symbols which hold

1791 to pop back to it. Handle unquoted section name as well as quoted
1792 section name. Don't crash on invalid strings.
1793 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

1814 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
1815 calculating opP->isiz; this permits the expression size to be
1816 determined as well, later on.
1818 * expr.c (clean_up_expression): Don't cancel the subtraction of
1821 * read.c (s_data), config/obj-coffbfd.c (obj_coff_data): If -R,

1828 before using the expression, instead of after.
1830 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
1832 * read.c (float_cons): Simplified parsing logic. If
1833 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.
1835 * symbols.c (colon): Rather than a special case for TC_HPPA,
1836 use new macro tc_frob_label.
1837 * config/tc-hppa.h (tc_frob_label): Define.
1839 * config/tc-mips.c: Many changes to support simple assembler

1853 (macro): Call mips_emit_delays before setting mips_noreorder.
1854 Increment and decrement mips_noreorder rather than using

2995 source directory, if that's not the current directory.
2997 * configure.in (per-host): Accept MIPS host with BSD version

3023 avoid some redefinition complaints on some systems.
3024 (const, volatile): Don't need these conditionally defined if we
3025 use CONST and VOLATILE from ansidecl.h.
3026 (seg_name): Use CONST, not const.
3028 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3030 * config/tc-mips.c: Reindented to GNU standards.

3034 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3035 (fixup_segment): Add a29k special case; the linker is not prepared
3036 to see a segment offset here.

3041 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3043 * Makefile.in: add dvi target; as-$(config).texinfo might live in
3044 srcdir, might be in objdir.

3063 * Makefile.in (targ-cpu.o): Depend on config.h.
3065 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3067 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3068 dropping a space immediately following an identifier.
3069 * expr.c, write.c: Rewrote assert expressions to not use multiple
3070 lines; I don't think that can be done portably.
3071 * config/tc-mips.c (macro): Use $AT if target register is zero in
3072 load instruction, which it can be for a floating point load.
3074 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3095 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3097 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3098 to be on a single line.
3100 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

3146 prototypes for all static functions. Moved existing minimal
3147 debugging format support info #ifndef OBJ_ECOFF blocks.

3196 * make-gas.com: Find obstack.obj if it's not in the current
3198 * read.c (s_ignore): Don't declare is_end_of_line. It's
3199 redundant, and triggers a VMS gcc compiler bug.
3201 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3202 current segment as an argument. (Ignored in all cases but VMS.)
3203 All callers and definitions changed.

3500 md_relax_table): Use default zero initialization.
3501 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3502 latter, instead of selecting with preprocessor conditionals.
3504 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3506 * configure.in: recognise all sparclite variants

3516 * expr.c (operand): If character other than comma or newline is a
3517 logical end-of-line character, use the newline case.
3518 From Eric Youngdale:
3519 (operand): Set X_add_number field for floating-point numbers.
3520 (operand): Treat zero byte as end-of-operand.
3522 * configure.in (per-target): Look for with_bfd_assembler option.
3523 For now, only accept "no", until the merge is done.
3525 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3526 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

3532 * expr.c: Add "const" modifier to hex_value.
3533 * symbols.c: Finish conversion to S_* macros in the VMS only
3534 parts of the program. Add "const" modifier to
3535 md_[long,short]_jump_size. Remove declaration of const_flag
3536 (which will be declared in obj-vms.h).
3537 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3538 Fix arguments to VMS_write_object_file.
3539 * config-gas.com: New file. Script for VMS systems to set up the
3540 configuration to build gas for VMS, and create config.status.
3541 * make-gas.com: Redone to work with new scheme.
3542 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3544 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

3547 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3548 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3549 types of malformed stabs. Change parsing algorithm so that we are
3550 more certain of having all of the information that we need on hand.
3551 * obj-vms.c (final_forward_reference): New function, used to help
3552 resolve the data types of as many struct elements as possible
3553 when some part of the struct is not fully defined by the compiler.

3556 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3557 as symbols as well in the object file. Look for external functions
3558 that start with "__vt.", and turn them into variables, since the
3559 g++ compiler is incapable of doing this.
3560 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3562 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
3563 * input-scrub.c (as_where): Fix bug where as would crash if we did not
3564 have the name of the source file yet.
3565 * config/ho-vms.h: define HO_VMS, not HO_VAX.
3567 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
3569 * read.c (s_data): Always use "data_section", since it'll map to
3570 SEG_DATA or SEG_E1 if needed.
3571 (s_lcomm): Likewise with bss_section.
3572 (s_fill): Use memset, not bzero.
3574 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

3596 (big_section, reg_section, pass1_section, diff_section,
3597 absent_section, text_section, data_section, bss_section): If
3598 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3599 mapping to segT enum values.
3600 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3601 if these are used or defined, if BFD_ASSEMBLER.
3602 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3603 subseg_new split into two functions.
3604 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3606 * as.h (volatile): Don't define if already defined.
3607 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3609 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3610 declare with format attribute for -Wformat checking.
3612 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3614 * app.c, config/tc-*.c: Don't include read.h, since it is already
3617 * These are based on patches from Minh Tran-le
3618 <mtranle@paris.intellicorp.com>.
3619 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3620 obj_format coffbfd and gas_target i386coff for target.
3621 (i[34]86-*-isc*): New host (uses sysv).
3622 * config/i386aix.mt: Removed (no longer used).
3623 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3625 (LDFLAGS): Added, defined as -shlib.
3626 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3627 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3628 (DOT_LABEL_PREFIX): Define.
3629 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3630 name rather than L0\001.
3631 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3633 * symbols.c, symbols.h (local_bss_counter): Removed.

3642 (size_section): Restored sanity check.
3643 (do_relocs_for): Base section address on s_paddr rather than
3644 computing it. Adjust a29k R_IHIHALF special case to account for
3645 section paddr (used to require paddr to be zero). If there are no
3646 reclos, set s_relptr to 0. Set relocation size in object_headers.
3647 (fill_section): Always set s_vaddr here, removing
3648 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3649 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3650 Set STYP_INFO for .comment.
3651 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
3652 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

3654 H_{SET,GET}_* macros.
3655 (do_linenos_for): Set lineno size in object_headers.
3656 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3657 set s_vaddr here. If string_byte_count remains 4, set it back to
3658 0, and only write strings out if there are some. Call
3659 fill_section before do_relocs_for and do_linenos_for.
3660 (obj_coff_section): Handle optional quoted second argument giving
3661 section characteristics.
3662 (obj_coff_bss): Added to handle .bss.
3663 (obj_coff_ident): Added to handle .ident (puts string in .comment

3683 (do_scrub_next_char): For \", return " not '.
3684 (symbol_chars): Now const.
3686 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3687 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3689 * config/obj-coff.h: Don't use #elif.
3691 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3692 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
3694 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
3696 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

3716 SEG_BSS, fill with NOP_OPCODE.
3717 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
3718 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
3719 using ZERO_BASED_SEGMENTS.
3720 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
3721 never set segment address for SEG_E2 (.bss) and don't write out
3722 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3723 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3724 definitions, and don't merge tags with non-tags. Check for .bf
3725 rather than just checking whether the second character is b and
3726 the third character is f.
3727 (obj_coff_val): gcc can generate values which we don't handle
3728 correctly; discard information for now, since it only affects the
3729 debugging information.
3730 (tag_find_or_name): Don't insert tags in the symbol table.
3731 (yank_symbols): Don't merge labels.
3732 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3751 * config/tc-i386.c (md_pseudo_table): For 386bsd and linux, do
3752 power-of-two alignment for .align.
3754 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
3755 and leave everything else alone.

3878 could be doing emulation.
3880 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3883 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

3953 * Support for i386-sysv.
3954 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

3996 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
3997 #elif, since it is not supported by old compilers.
3998 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
3999 couple of expressions in tc-m68k.c.
4001 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4003 * read.c (cons): If NO_RELOC is defined, use it.
4005 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4007 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4009 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4010 local labels to start with a .) and set REGISTER_PREFIX to %.
4011 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

4029 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4030 sections starting from zero, rather than making them consecutive.
4031 This makes subsequent reloc calculations easier, esp if the object
4032 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4033 allocate lcomm in .data rather than in .bss. It seems that some
4034 tools can't cope with a non-zero sized bss before linkage.
4036 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4038 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4057 * Makefile.in (install): if $(tooldir) exists, install as in
4060 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4062 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4063 .word is < -32768 or > 32767. The -J flag causes the error to be
4064 ignored. This is to catch over-sized switches generated by gcc on
4065 systems which don't support the broken .word hack.
4066 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4067 write.c (fixup_segment): check for signed .word overflow if
4068 WARN_SIGNED_OVERFLOW_WORD.

4087 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4089 * input-scrub.c (input_scrub_push): call input_file_begin, not
4091 messages.c (as_perror): print ": " between the passed in error and
4092 the strerror, like perror does.

4097 From Steve Chamberlain:
4098 Makefile.in: Handle m68*-*-coff*.
4099 read.c, read.h: add mult argument to s_space
4101 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4102 Motorola and MIT syntax; gas can now assemble either type of

4111 (fixup_segment) set fx_subsy to 0.
4112 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4114 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4117 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4119 * Makefile.in (LIBS): Include opcode library.

4144 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4146 * config/tc-m68k.c (init_table): Now const. Always include 68851
4147 data, so that "bc" is available to 68040 cache instructions.
4148 Added "tt0", "tt1", and 68ec030 variants.
4149 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4150 (enum _register): Added TT0, TT1.
4151 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4152 line number correctly in "internal error" messages. Don't print
4153 architecture-mismatch message for operand errors.
4155 From Colin Smith (colin@wrs.com):
4156 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4157 than install_operand.

4173 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
4174 so that we can assemble hand-written libgcc code.

4178 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4179 has already been formatted (but may still contain %-characters).
4182 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4184 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4185 written with indirection on the last two operands, which can be
4186 either data or address registers. Added a new operand type 'r'
4187 which accepts either register type. Added '(' to notend stuff in
4188 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
4190 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

4204 (relax_align): If linkrelax, provide extra padding.
4206 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
4207 their not having symbols associated.
4209 * tc-i960.c (norelax, instrument_branches): Default initializer is
4211 (linkrelax): Delete variable definition.

4235 being used with args swapped, causing occasional lossage when
4236 refilling buffers after an include file.

4240 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
4241 version. Discard bogus DONTDEF version.

4246 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
4247 selected architecture, print a message saying so and listing what

4298 processor/opcode mismatch, so reword the error message.
4299 (md_assemble): If no CPU has been set (even if FPU/PMMU
4300 characteristics have been), default to 68020. Don't need extra
4301 quotes around error string.

4385 * write.c (write_object_file): keep the fix_tail clean, which
4386 fixes a bug in -R where relocations were being lost.
4388 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
4390 * configure.in: recognize m680x0 as having sun3 emulation mode for

4435 start addresses to match required alignment.
4437 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4439 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4440 where gcc looks for it.
4442 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4444 * Makefile.in: Changed some lines to be less confusing for some

4510 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4512 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4514 * expr.c (operand): if can't work out what sort of operand it is,
4515 then look through FLT_CHARS for a hint.
4517 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4519 * Makefile.in, configure.in: removed traces of namesubdir,
4520 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4521 copyrights to '92, changed some from Cygnus to FSF.
4523 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4524 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4525 copyrights to '92, changed some from Cygnus to FSF.
4527 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4529 * expr.c: If an expression is single comma, then return with
4530 SEG_ABSENT rather than an error - since the sparc front end does
4531 really strange things with things like fbge,a
4533 * as.h: include bfd.h if using many sections
4534 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4535 local labels didn't work.
4536 * listing.c (list_symbol_table): don't core dump when there's no
4538 * write.c, write.h: call fix_new with the right number of args on
4540 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4543 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4545 * app.c: MRI compatibility - allow single quote to start a string.
4546 * as.c: fix typo recently introduced.
4547 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4548 * expr.c: Much rewriting, to accomodate MRI syntax for
4549 expressions. Also easier to read now.
4550 * listing.c: Put back defuns
4551 * read.c: modified to accept MRI syntax, put back listing pseudo
4552 ops so that an assembler built with NO_LISTING ignores list ops
4554 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4555 machine is a SPARC or a 29K.
4556 * config/obj-aout.c: added s_sect pseudo op
4557 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4558 fill in the timestamp.
4559 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4560 anymore, define all the relocs which the tc-<x> bit will use so we
4561 can translate from them to the coff types.
4562 * config/tc-a29k.c: reloc_type isn't ane enum any more
4563 * config/tc-m68k.c: Added NO_RELOC definition.
4565 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4567 * Makefile.in: put header files before C source for TAGS; remove
4568 references to non-existent syscalls.h.
4570 * read.c, write.c subsegs.c: back out the .bss changes.
4572 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4574 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4578 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4580 * symbols.c (local_label_name): symbols now start with ^A.
4582 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4583 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4584 generate these sections. .align: will use NOP_OPCODE or 0
4585 for padding. This is just for being nice to the
4588 * expr.c (operand): changed to generate local label "\001L0"
4589 starting with a ^A so that it is recognized as a local label.
4591 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4593 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4594 i/o opcodes - inb, inw, outb and outw. string manipulation with
4595 att syntax - scmp, slod, smov, ssca, ssto.
4597 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4598 to just after .file .
4600 In obj_crawl_symbol_chain() where it tries to put the external
4601 symbols apart, with the condition:
4602 (!S_IS_DEFINED(symbolP) &&
4603 !S_IS_DEBUG(symbolP) &&
4604 !SF_GET_STATICS(symbolP))
4605 it was moving too many symbols out. So I switch it back to the
4607 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4609 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4610 so that we don't use the F_RELFLG which make the linker complain
4611 that somebody has stripped the relocation info.
4613 Also, the AIX ld program require that the relocation table
4614 is sorted by r_vaddr like the standard ATT assembler does.
4616 [he also changed the sizeof(struct ...)'s into the coff
4617 style FOOSZ macros. I'm not sure this is right, but I can't
4618 remember why. xoxorich.]
4620 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4622 * Makefile.in, configure.in, doc: use the doc. Build it, install

4627 * read.c: white space and comments only.
4629 * configure.in: use the new atof-ns32.c for ns32k.
4631 * write.c: comment change only.
4633 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4634 aren't yet integrated.
4636 * tc-i860.[hc]: blew off the dust. Something must still be done
4637 about conflicting relocation types.
4639 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4642 * tc-i960.c, tc-sparc.c: white space and comments only.
4644 * tc-a29k.h: delete duplicate macro definition.
4646 * new file atof-ns32k.c copied from hack's last unreleased gas.
4648 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4650 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4653 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4654 ChangeLog's prior to this are sketchy at best. I have logs.
4655 They just aren't ChangeLogs.
