813 * config/tc-sparc.c (md_end): Function deleted.

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

834 conditional code -- try to group conditional code together
835 into a few places. Make all functions and variables which
836 are only used within tc-hppa.c static. PARAMize all functions.
837 Add comments to functions. Delete unused functions, variables,
838 #defines, etc. Delete unused members within structures. Delete
839 ldil;ble hacks -- it is believed they were installed to work
840 around old gas bugs. Avoid using mixed case for local
841 functions, variables, and structures. Fix formatting problems
842 not found by GNU-indent. Add FIXME notices for things which
843 should be worked on the near future. Delete lots of old
844 useless (1.36 PA-SOM) code.

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

1921 * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
1922 are also magic, and have special default flag settings.
1923 (obj_elf_frob_symbol): Since the return value from this function
1924 isn't used, don't bother calling obj_elf_write_symbol_p, since it
1925 doesn't accomplish anything else.

1937 undefined_section for the return value.
1939 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
1940 pseudo-op with a poc_handler field of NULL, ignore it and treat it
1941 as an instruction instead.

1959 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
1960 *-*-solaris case, and move to before *-sysv* case that wants to
1961 set obj_format to coff.

1987 * Extensive changes to permit symbols to contain any expression
1988 type and to delay the computation of the expression until the
1989 value is actually needed. This permits setting symbols to values
1990 calculated based on object code size. Expressions were changed to
1991 no longer be in a section, to stop the overloading of segment and
1992 expression type that previously occurred.
1994 * as.c (big_section, pass1_section, diff_section, absent_section):
1996 (expr_section): Added (used for dummy symbols which hold

2080 (previous_section, previous_subsection): New vars.
2081 (obj_elf_section): Save current place in case DWARF code wants us
2082 to pop back to it. Handle unquoted section name as well as quoted
2083 section name. Don't crash on invalid strings.
2084 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

3310 process relocs if there aren't any relocs to process. Avoids
3311 malloc/free bug on SCO too.

3359 dropping a space immediately following an identifier.
3360 * expr.c, write.c: Rewrote assert expressions to not use multiple
3361 lines; I don't think that can be done portably.
3362 * config/tc-mips.c (macro): Use $AT if target register is zero in
3363 load instruction, which it can be for a floating point load.
3365 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3437 prototypes for all static functions. Moved existing minimal
3438 debugging format support info #ifndef OBJ_ECOFF blocks.

3487 * make-gas.com: Find obstack.obj if it's not in the current
3489 * read.c (s_ignore): Don't declare is_end_of_line. It's
3490 redundant, and triggers a VMS gcc compiler bug.
3492 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3493 current segment as an argument. (Ignored in all cases but VMS.)
3494 All callers and definitions changed.

3790 * config/tc-sparc.c (architecture_requested, warn_on_bump,
3791 md_relax_table): Use default zero initialization.
3792 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3793 latter, instead of selecting with preprocessor conditionals.
3795 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3797 * configure.in: recognise all sparclite variants
3799 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3801 * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --
3802 accidentally changed to use subseg_change where it should have
3805 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3807 * expr.c (operand): If character other than comma or newline is a
3808 logical end-of-line character, use the newline case.
3809 From Eric Youngdale:
3810 (operand): Set X_add_number field for floating-point numbers.
3811 (operand): Treat zero byte as end-of-operand.
3813 * configure.in (per-target): Look for with_bfd_assembler option.
3814 For now, only accept "no", until the merge is done.
3816 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3817 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
3818 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
3819 * read.c: Finish conversion to S_* macros in the VMS only
3820 parts of the program. Add "const" modifier to hex_value.
3821 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
3823 * expr.c: Add "const" modifier to hex_value.
3824 * symbols.c: Finish conversion to S_* macros in the VMS only
3825 parts of the program. Add "const" modifier to
3826 md_[long,short]_jump_size. Remove declaration of const_flag
3827 (which will be declared in obj-vms.h).
3828 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3829 Fix arguments to VMS_write_object_file.
3830 * config-gas.com: New file. Script for VMS systems to set up the
3831 configuration to build gas for VMS, and create config.status.
3832 * make-gas.com: Redone to work with new scheme.
3833 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3835 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
3836 will swap bytes if needed on a big endian system. Use throughout
3838 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3839 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3840 types of malformed stabs. Change parsing algorithm so that we are
3841 more certain of having all of the information that we need on hand.
3842 * obj-vms.c (final_forward_reference): New function, used to help
3843 resolve the data types of as many struct elements as possible
3844 when some part of the struct is not fully defined by the compiler.
3845 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
3847 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3848 as symbols as well in the object file. Look for external functions
3849 that start with "__vt.", and turn them into variables, since the
3850 g++ compiler is incapable of doing this.
3851 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3853 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
3854 * input-scrub.c (as_where): Fix bug where as would crash if we did not
3855 have the name of the source file yet.
3856 * config/ho-vms.h: define HO_VMS, not HO_VAX.
3858 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
3860 * read.c (s_data): Always use "data_section", since it'll map to
3861 SEG_DATA or SEG_E1 if needed.
3862 (s_lcomm): Likewise with bss_section.
3863 (s_fill): Use memset, not bzero.
3865 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
3867 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

3881 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
3882 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

3886 (section_alignment): Declare only if not BFD_ASSEMBLER.
3887 (big_section, reg_section, pass1_section, diff_section,
3888 absent_section, text_section, data_section, bss_section): If
3889 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3890 mapping to segT enum values.
3891 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3892 if these are used or defined, if BFD_ASSEMBLER.
3893 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3894 subseg_new split into two functions.
3895 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3897 * as.h (volatile): Don't define if already defined.
3898 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3900 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3901 declare with format attribute for -Wformat checking.
3903 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3905 * app.c, config/tc-*.c: Don't include read.h, since it is already
3908 * These are based on patches from Minh Tran-le
3909 <mtranle@paris.intellicorp.com>.
3910 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3911 obj_format coffbfd and gas_target i386coff for target.
3912 (i[34]86-*-isc*): New host (uses sysv).
3913 * config/i386aix.mt: Removed (no longer used).
3914 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3916 (LDFLAGS): Added, defined as -shlib.
3917 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3918 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3919 (DOT_LABEL_PREFIX): Define.
3920 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3921 name rather than L0\001.
3922 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3924 * symbols.c, symbols.h (local_bss_counter): Removed.
3925 * write.c (write_object_file): bss no longer uses
3926 local_bss_counter. Pass correct data and bss size to
3927 VMS_write_object_file.

3933 (size_section): Restored sanity check.
3934 (do_relocs_for): Base section address on s_paddr rather than
3935 computing it. Adjust a29k R_IHIHALF special case to account for
3936 section paddr (used to require paddr to be zero). If there are no
3937 reclos, set s_relptr to 0. Set relocation size in object_headers.
3938 (fill_section): Always set s_vaddr here, removing
3939 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3940 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3941 Set STYP_INFO for .comment.
3942 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
3943 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

3945 H_{SET,GET}_* macros.
3946 (do_linenos_for): Set lineno size in object_headers.
3947 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3948 set s_vaddr here. If string_byte_count remains 4, set it back to
3949 0, and only write strings out if there are some. Call
3950 fill_section before do_relocs_for and do_linenos_for.
3951 (obj_coff_section): Handle optional quoted second argument giving
3952 section characteristics.
3953 (obj_coff_bss): Added to handle .bss.
3954 (obj_coff_ident): Added to handle .ident (puts string in .comment

3957 (fixup_mdeps): Change to segment. Call frag_wane after
3959 (fixup_segment): Explicitly check S_IS_COMMON before making 386
3960 adjustment (already happened only for common symbols, but this is
3962 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

3974 (do_scrub_next_char): For \", return " not '.
3975 (symbol_chars): Now const.
3977 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3978 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3980 * config/obj-coff.h: Don't use #elif.
3982 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3983 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
3985 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

4009 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4010 using ZERO_BASED_SEGMENTS.
4011 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4012 never set segment address for SEG_E2 (.bss) and don't write out
4013 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4014 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4015 definitions, and don't merge tags with non-tags. Check for .bf
4016 rather than just checking whether the second character is b and
4017 the third character is f.
4018 (obj_coff_val): gcc can generate values which we don't handle
4019 correctly; discard information for now, since it only affects the
4020 debugging information.

4022 (yank_symbols): Don't merge labels.
4023 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4264 fix i960+non-bfd coff bit rot.
4265 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
4266 support for C source listings. (obj_coff_endef): look in the right
4267 part of the symbol for the symbol name
4269 * tc-m68k.c (get_num): make it work for all segments, not just the
4272 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
4274 * configure.in: recognize i386-*-bsd emulation.

4283 * tc-z8k.c: lots of bug fixes
4285 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4287 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4288 #elif, since it is not supported by old compilers.
4289 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4290 couple of expressions in tc-m68k.c.
4292 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4294 * read.c (cons): If NO_RELOC is defined, use it.
4296 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4298 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4300 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4301 local labels to start with a .) and set REGISTER_PREFIX to %.
4302 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4304 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

4320 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4321 sections starting from zero, rather than making them consecutive.
4322 This makes subsequent reloc calculations easier, esp if the object
4323 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4324 allocate lcomm in .data rather than in .bss. It seems that some
4325 tools can't cope with a non-zero sized bss before linkage.
4327 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4329 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4348 * Makefile.in (install): if $(tooldir) exists, install as in
4351 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4353 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4354 .word is < -32768 or > 32767. The -J flag causes the error to be
4355 ignored. This is to catch over-sized switches generated by gcc on
4356 systems which don't support the broken .word hack.
4357 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4358 write.c (fixup_segment): check for signed .word overflow if
4359 WARN_SIGNED_OVERFLOW_WORD.

4378 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4380 * input-scrub.c (input_scrub_push): call input_file_begin, not
4382 messages.c (as_perror): print ": " between the passed in error and
4383 the strerror, like perror does.
4385 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

4388 From Steve Chamberlain:
4389 Makefile.in: Handle m68*-*-coff*.
4390 read.c, read.h: add mult argument to s_space
4392 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4393 Motorola and MIT syntax; gas can now assemble either type of
4395 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4401 (write_object_file) call fixup_mdeps
4402 (fixup_segment) set fx_subsy to 0.
4403 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4405 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4408 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4410 * Makefile.in (LIBS): Include opcode library.

4435 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4437 * config/tc-m68k.c (init_table): Now const. Always include 68851
4438 data, so that "bc" is available to 68040 cache instructions.
4439 Added "tt0", "tt1", and 68ec030 variants.
4440 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4441 (enum _register): Added TT0, TT1.
4442 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4443 line number correctly in "internal error" messages. Don't print
4444 architecture-mismatch message for operand errors.
4446 From Colin Smith (colin@wrs.com):
4447 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

4469 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4470 has already been formatted (but may still contain %-characters).
4473 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4475 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4476 written with indirection on the last two operands, which can be
4477 either data or address registers. Added a new operand type 'r'
4478 which accepts either register type. Added '(' to notend stuff in
4479 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

4751 * Makefile.in: pass down MAKEINFO explicitly on info.
4753 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
4755 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4757 * flonum-const.c: renamed flonum-konst.c to stop dos name
4760 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
4762 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
4763 tc-m68k.h to te-sun3.h.
4765 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
4767 * configure.in: vxworks68 gets te-sun3.h.
4769 * expr.c: remove limitation that local_labels_dollar or
4770 local_labels_fb must be < 10.
4772 * symbols.c: remove local_labels_dollar, replace with a function
4773 interface for a sparse array. All users adjusted.
4775 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
4777 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4779 * doc/Makefile.in: commented out line for building as-all.texinfo.
4782 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
4784 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
4786 * Makefile.in: added check target.
4788 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4790 * Makefile.in: added tooldir and program_prefix.
4792 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
4794 * write.{c,h} (fix_new): Make these declarations consistent.
4796 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
4798 * Makefile.in (strerror.o): Add rule so that broken Sun make can
4801 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4803 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4805 * expr.c (operand): if can't work out what sort of operand it is,
4806 then look through FLT_CHARS for a hint.
4808 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4810 * Makefile.in, configure.in: removed traces of namesubdir,
4811 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4812 copyrights to '92, changed some from Cygnus to FSF.
4814 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4815 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4816 copyrights to '92, changed some from Cygnus to FSF.
4818 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4820 * expr.c: If an expression is single comma, then return with
4821 SEG_ABSENT rather than an error - since the sparc front end does
4822 really strange things with things like fbge,a
4824 * as.h: include bfd.h if using many sections
4825 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4826 local labels didn't work.
4827 * listing.c (list_symbol_table): don't core dump when there's no
4829 * write.c, write.h: call fix_new with the right number of args on
4831 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4834 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4836 * app.c: MRI compatibility - allow single quote to start a string.
4837 * as.c: fix typo recently introduced.
4838 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4839 * expr.c: Much rewriting, to accomodate MRI syntax for
4840 expressions. Also easier to read now.
4841 * listing.c: Put back defuns
4842 * read.c: modified to accept MRI syntax, put back listing pseudo
4843 ops so that an assembler built with NO_LISTING ignores list ops
4845 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4846 machine is a SPARC or a 29K.
4847 * config/obj-aout.c: added s_sect pseudo op
4848 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4849 fill in the timestamp.
4850 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4851 anymore, define all the relocs which the tc-<x> bit will use so we
4852 can translate from them to the coff types.
4853 * config/tc-a29k.c: reloc_type isn't ane enum any more
4854 * config/tc-m68k.c: Added NO_RELOC definition.
4856 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4858 * Makefile.in: put header files before C source for TAGS; remove
4859 references to non-existent syscalls.h.
4861 * read.c, write.c subsegs.c: back out the .bss changes.
4863 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4865 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4869 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4871 * symbols.c (local_label_name): symbols now start with ^A.
4873 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4874 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4875 generate these sections. .align: will use NOP_OPCODE or 0
4876 for padding. This is just for being nice to the
4879 * expr.c (operand): changed to generate local label "\001L0"
4880 starting with a ^A so that it is recognized as a local label.
4882 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4884 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4885 i/o opcodes - inb, inw, outb and outw. string manipulation with
4886 att syntax - scmp, slod, smov, ssca, ssto.
4888 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4889 to just after .file .
4891 In obj_crawl_symbol_chain() where it tries to put the external
4892 symbols apart, with the condition:
4893 (!S_IS_DEFINED(symbolP) &&
4894 !S_IS_DEBUG(symbolP) &&
4895 !SF_GET_STATICS(symbolP))
4896 it was moving too many symbols out. So I switch it back to the
4898 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4900 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4901 so that we don't use the F_RELFLG which make the linker complain
4902 that somebody has stripped the relocation info.
4904 Also, the AIX ld program require that the relocation table
4905 is sorted by r_vaddr like the standard ATT assembler does.
4907 [he also changed the sizeof(struct ...)'s into the coff
4908 style FOOSZ macros. I'm not sure this is right, but I can't
4909 remember why. xoxorich.]
4911 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4913 * Makefile.in, configure.in, doc: use the doc. Build it, install
4916 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4918 * read.c: white space and comments only.
4920 * configure.in: use the new atof-ns32.c for ns32k.
4922 * write.c: comment change only.
4924 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4925 aren't yet integrated.
4927 * tc-i860.[hc]: blew off the dust. Something must still be done
4928 about conflicting relocation types.
4930 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4933 * tc-i960.c, tc-sparc.c: white space and comments only.
4935 * tc-a29k.h: delete duplicate macro definition.
4937 * new file atof-ns32k.c copied from hack's last unreleased gas.
4939 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4941 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4944 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4945 ChangeLog's prior to this are sketchy at best. I have logs.
4946 They just aren't ChangeLogs.
