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

860 into a few places. Make all functions and variables which
861 are only used within tc-hppa.c static. PARAMize all functions.
862 Add comments to functions. Delete unused functions, variables,
863 #defines, etc. Delete unused members within structures. Delete
864 ldil;ble hacks -- it is believed they were installed to work
865 around old gas bugs. Avoid using mixed case for local
866 functions, variables, and structures. Fix formatting problems
867 not found by GNU-indent. Add FIXME notices for things which
868 should be worked on the near future. Delete lots of old

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

1947 are also magic, and have special default flag settings.
1948 (obj_elf_frob_symbol): Since the return value from this function

2012 * Extensive changes to permit symbols to contain any expression
2013 type and to delay the computation of the expression until the
2014 value is actually needed. This permits setting symbols to values
2015 calculated based on object code size. Expressions were changed to
2016 no longer be in a section, to stop the overloading of segment and
2017 expression type that previously occurred.
2019 * as.c (big_section, pass1_section, diff_section, absent_section):
2021 (expr_section): Added (used for dummy symbols which hold

2221 sy_resolved and sy_resolving single bit fields.
2222 * symbols.c (symbol_new): Don't initialize sy_forward field.

3386 lines; I don't think that can be done portably.
3387 * config/tc-mips.c (macro): Use $AT if target register is zero in
3388 load instruction, which it can be for a floating point load.

3462 prototypes for all static functions. Moved existing minimal
3463 debugging format support info #ifndef OBJ_ECOFF blocks.

3514 * read.c (s_ignore): Don't declare is_end_of_line. It's
3515 redundant, and triggers a VMS gcc compiler bug.
3517 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3518 current segment as an argument. (Ignored in all cases but VMS.)
3519 All callers and definitions changed.

3815 * config/tc-sparc.c (architecture_requested, warn_on_bump,
3816 md_relax_table): Use default zero initialization.
3817 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3818 latter, instead of selecting with preprocessor conditionals.
3820 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3822 * configure.in: recognise all sparclite variants
3824 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

3830 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3832 * expr.c (operand): If character other than comma or newline is a
3833 logical end-of-line character, use the newline case.
3834 From Eric Youngdale:
3835 (operand): Set X_add_number field for floating-point numbers.
3836 (operand): Treat zero byte as end-of-operand.
3838 * configure.in (per-target): Look for with_bfd_assembler option.
3839 For now, only accept "no", until the merge is done.
3841 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3842 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
3843 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
3844 * read.c: Finish conversion to S_* macros in the VMS only
3845 parts of the program. Add "const" modifier to hex_value.
3846 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
3848 * expr.c: Add "const" modifier to hex_value.
3849 * symbols.c: Finish conversion to S_* macros in the VMS only
3850 parts of the program. Add "const" modifier to
3851 md_[long,short]_jump_size. Remove declaration of const_flag
3852 (which will be declared in obj-vms.h).
3853 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3854 Fix arguments to VMS_write_object_file.
3855 * config-gas.com: New file. Script for VMS systems to set up the
3856 configuration to build gas for VMS, and create config.status.
3857 * make-gas.com: Redone to work with new scheme.
3858 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3860 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
3861 will swap bytes if needed on a big endian system. Use throughout
3863 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3864 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3865 types of malformed stabs. Change parsing algorithm so that we are
3866 more certain of having all of the information that we need on hand.
3867 * obj-vms.c (final_forward_reference): New function, used to help
3868 resolve the data types of as many struct elements as possible
3869 when some part of the struct is not fully defined by the compiler.
3870 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
3872 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3873 as symbols as well in the object file. Look for external functions
3874 that start with "__vt.", and turn them into variables, since the
3875 g++ compiler is incapable of doing this.
3876 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3878 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
3879 * input-scrub.c (as_where): Fix bug where as would crash if we did not
3880 have the name of the source file yet.
3881 * config/ho-vms.h: define HO_VMS, not HO_VAX.
3883 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
3885 * read.c (s_data): Always use "data_section", since it'll map to
3886 SEG_DATA or SEG_E1 if needed.
3887 (s_lcomm): Likewise with bss_section.
3888 (s_fill): Use memset, not bzero.
3890 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

3911 (section_alignment): Declare only if not BFD_ASSEMBLER.
3912 (big_section, reg_section, pass1_section, diff_section,
3913 absent_section, text_section, data_section, bss_section): If
3914 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3915 mapping to segT enum values.
3916 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3917 if these are used or defined, if BFD_ASSEMBLER.
3918 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3919 subseg_new split into two functions.
3920 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3922 * as.h (volatile): Don't define if already defined.
3923 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3925 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3926 declare with format attribute for -Wformat checking.
3928 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3930 * app.c, config/tc-*.c: Don't include read.h, since it is already
3933 * These are based on patches from Minh Tran-le
3934 <mtranle@paris.intellicorp.com>.
3935 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3936 obj_format coffbfd and gas_target i386coff for target.
3937 (i[34]86-*-isc*): New host (uses sysv).
3938 * config/i386aix.mt: Removed (no longer used).
3939 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3941 (LDFLAGS): Added, defined as -shlib.
3942 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3943 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3944 (DOT_LABEL_PREFIX): Define.
3945 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3946 name rather than L0\001.
3947 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3949 * symbols.c, symbols.h (local_bss_counter): Removed.
3950 * write.c (write_object_file): bss no longer uses
3951 local_bss_counter. Pass correct data and bss size to
3952 VMS_write_object_file.

3958 (size_section): Restored sanity check.
3959 (do_relocs_for): Base section address on s_paddr rather than
3960 computing it. Adjust a29k R_IHIHALF special case to account for
3961 section paddr (used to require paddr to be zero). If there are no
3962 reclos, set s_relptr to 0. Set relocation size in object_headers.
3963 (fill_section): Always set s_vaddr here, removing
3964 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3965 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3966 Set STYP_INFO for .comment.
3967 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
3968 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

3970 H_{SET,GET}_* macros.
3971 (do_linenos_for): Set lineno size in object_headers.
3972 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3973 set s_vaddr here. If string_byte_count remains 4, set it back to
3974 0, and only write strings out if there are some. Call
3975 fill_section before do_relocs_for and do_linenos_for.
3976 (obj_coff_section): Handle optional quoted second argument giving
3977 section characteristics.
3978 (obj_coff_bss): Added to handle .bss.
3979 (obj_coff_ident): Added to handle .ident (puts string in .comment

3982 (fixup_mdeps): Change to segment. Call frag_wane after
3984 (fixup_segment): Explicitly check S_IS_COMMON before making 386
3985 adjustment (already happened only for common symbols, but this is
3987 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

3999 (do_scrub_next_char): For \", return " not '.
4000 (symbol_chars): Now const.
4002 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4003 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4005 * config/obj-coff.h: Don't use #elif.
4007 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4008 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

4034 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4035 using ZERO_BASED_SEGMENTS.
4036 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4037 never set segment address for SEG_E2 (.bss) and don't write out
4038 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4039 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4040 definitions, and don't merge tags with non-tags. Check for .bf
4041 rather than just checking whether the second character is b and
4042 the third character is f.
4043 (obj_coff_val): gcc can generate values which we don't handle
4044 correctly; discard information for now, since it only affects the
4045 debugging information.
4046 (tag_find_or_name): Don't insert tags in the symbol table.
4047 (yank_symbols): Don't merge labels.
4048 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4230 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4231 constant will not fit in an immediate field.
4232 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

4267 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4269 * Support for i386-sysv.
4270 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
4271 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
4272 be used to set them all to zero as was done before.
4273 (fill_section): segment addresses now set in write_object_file.
4274 (fill_section): Don't set STYP_NOLOAD for .bss section.
4275 (fixup_segment): 386 uses strange common symbol format.
4276 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
4277 compatibility with SVR3.2 linker.
4278 * configure.in: i386-sysv and i386-sco use coffbfd.

4290 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
4291 support for C source listings. (obj_coff_endef): look in the right
4292 part of the symbol for the symbol name
4294 * tc-m68k.c (get_num): make it work for all segments, not just the
4297 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

4308 * tc-z8k.c: lots of bug fixes
4310 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4312 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4313 #elif, since it is not supported by old compilers.
4314 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4315 couple of expressions in tc-m68k.c.
4317 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4319 * read.c (cons): If NO_RELOC is defined, use it.
4321 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4323 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4325 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4326 local labels to start with a .) and set REGISTER_PREFIX to %.
4327 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

4345 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4346 sections starting from zero, rather than making them consecutive.
4347 This makes subsequent reloc calculations easier, esp if the object
4348 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4349 allocate lcomm in .data rather than in .bss. It seems that some
4350 tools can't cope with a non-zero sized bss before linkage.
4352 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4354 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4376 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4378 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4379 .word is < -32768 or > 32767. The -J flag causes the error to be
4380 ignored. This is to catch over-sized switches generated by gcc on
4381 systems which don't support the broken .word hack.
4382 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4383 write.c (fixup_segment): check for signed .word overflow if
4384 WARN_SIGNED_OVERFLOW_WORD.

4403 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4405 * input-scrub.c (input_scrub_push): call input_file_begin, not
4407 messages.c (as_perror): print ": " between the passed in error and
4408 the strerror, like perror does.
4410 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

4413 From Steve Chamberlain:
4414 Makefile.in: Handle m68*-*-coff*.
4415 read.c, read.h: add mult argument to s_space
4417 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4418 Motorola and MIT syntax; gas can now assemble either type of
4420 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4428 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4430 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4433 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4435 * Makefile.in (LIBS): Include opcode library.

4462 * config/tc-m68k.c (init_table): Now const. Always include 68851
4463 data, so that "bc" is available to 68040 cache instructions.
4464 Added "tt0", "tt1", and 68ec030 variants.
4465 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4466 (enum _register): Added TT0, TT1.
4467 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4468 line number correctly in "internal error" messages. Don't print
4469 architecture-mismatch message for operand errors.

4494 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4495 has already been formatted (but may still contain %-characters).
4498 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4500 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4501 written with indirection on the last two operands, which can be
4502 either data or address registers. Added a new operand type 'r'
4503 which accepts either register type. Added '(' to notend stuff in
4504 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

4744 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4746 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
4748 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4750 * write.c (write_object_file): For b.out format, round up section
4751 start addresses to match required alignment.
4753 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4755 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4756 where gcc looks for it.
4758 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4760 * Makefile.in: Changed some lines to be less confusing for some
4763 * input-file.c: Conditionalize on _IOFBF, not VMS.
4765 * read.c, write.c: Change a series of ifdef/elif to
4766 ifdef/else/ifdef etc.
4768 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
4770 * symbols.c (fb_label_init): fix sizeof to memset.
4772 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
4774 * Makefile.in: install the man page.
4776 * Makefile.in: pass down MAKEINFO explicitly on info.
4778 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
4780 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4782 * flonum-const.c: renamed flonum-konst.c to stop dos name
4785 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
4787 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
4788 tc-m68k.h to te-sun3.h.
4790 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
4792 * configure.in: vxworks68 gets te-sun3.h.
4794 * expr.c: remove limitation that local_labels_dollar or
4795 local_labels_fb must be < 10.
4797 * symbols.c: remove local_labels_dollar, replace with a function
4798 interface for a sparse array. All users adjusted.
4800 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
4802 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4804 * doc/Makefile.in: commented out line for building as-all.texinfo.
4807 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
4809 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
4811 * Makefile.in: added check target.
4813 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4815 * Makefile.in: added tooldir and program_prefix.
4817 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
4819 * write.{c,h} (fix_new): Make these declarations consistent.
4821 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
4823 * Makefile.in (strerror.o): Add rule so that broken Sun make can
4826 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4828 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4830 * expr.c (operand): if can't work out what sort of operand it is,
4831 then look through FLT_CHARS for a hint.
4833 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4835 * Makefile.in, configure.in: removed traces of namesubdir,
4836 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4837 copyrights to '92, changed some from Cygnus to FSF.
4839 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4840 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4841 copyrights to '92, changed some from Cygnus to FSF.
4843 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4845 * expr.c: If an expression is single comma, then return with
4846 SEG_ABSENT rather than an error - since the sparc front end does
4847 really strange things with things like fbge,a
4849 * as.h: include bfd.h if using many sections
4850 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4851 local labels didn't work.
4852 * listing.c (list_symbol_table): don't core dump when there's no
4854 * write.c, write.h: call fix_new with the right number of args on
4856 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4859 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4861 * app.c: MRI compatibility - allow single quote to start a string.
4862 * as.c: fix typo recently introduced.
4863 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4864 * expr.c: Much rewriting, to accomodate MRI syntax for
4865 expressions. Also easier to read now.
4866 * listing.c: Put back defuns
4867 * read.c: modified to accept MRI syntax, put back listing pseudo
4868 ops so that an assembler built with NO_LISTING ignores list ops
4870 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4871 machine is a SPARC or a 29K.
4872 * config/obj-aout.c: added s_sect pseudo op
4873 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4874 fill in the timestamp.
4875 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4876 anymore, define all the relocs which the tc-<x> bit will use so we
4877 can translate from them to the coff types.
4878 * config/tc-a29k.c: reloc_type isn't ane enum any more
4879 * config/tc-m68k.c: Added NO_RELOC definition.
4881 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4883 * Makefile.in: put header files before C source for TAGS; remove
4884 references to non-existent syscalls.h.
4886 * read.c, write.c subsegs.c: back out the .bss changes.
4888 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4890 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4894 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4896 * symbols.c (local_label_name): symbols now start with ^A.
4898 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4899 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4900 generate these sections. .align: will use NOP_OPCODE or 0
4901 for padding. This is just for being nice to the
4904 * expr.c (operand): changed to generate local label "\001L0"
4905 starting with a ^A so that it is recognized as a local label.
4907 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4909 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4910 i/o opcodes - inb, inw, outb and outw. string manipulation with
4911 att syntax - scmp, slod, smov, ssca, ssto.
4913 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4914 to just after .file .
4916 In obj_crawl_symbol_chain() where it tries to put the external
4917 symbols apart, with the condition:
4918 (!S_IS_DEFINED(symbolP) &&
4919 !S_IS_DEBUG(symbolP) &&
4920 !SF_GET_STATICS(symbolP))
4921 it was moving too many symbols out. So I switch it back to the
4923 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4925 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4926 so that we don't use the F_RELFLG which make the linker complain
4927 that somebody has stripped the relocation info.
4929 Also, the AIX ld program require that the relocation table
4930 is sorted by r_vaddr like the standard ATT assembler does.
4932 [he also changed the sizeof(struct ...)'s into the coff
4933 style FOOSZ macros. I'm not sure this is right, but I can't
4934 remember why. xoxorich.]
4936 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4938 * Makefile.in, configure.in, doc: use the doc. Build it, install
4941 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4943 * read.c: white space and comments only.
4945 * configure.in: use the new atof-ns32.c for ns32k.
4947 * write.c: comment change only.
4949 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4950 aren't yet integrated.
4952 * tc-i860.[hc]: blew off the dust. Something must still be done
4953 about conflicting relocation types.
4955 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4958 * tc-i960.c, tc-sparc.c: white space and comments only.
4960 * tc-a29k.h: delete duplicate macro definition.
4962 * new file atof-ns32k.c copied from hack's last unreleased gas.
4964 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4966 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4969 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4970 ChangeLog's prior to this are sketchy at best. I have logs.
4971 They just aren't ChangeLogs.
