1852 BFD_RELOC_MIPS_GPREL. Added new case a.
1853 (set_at, load_register, macro): Changed calls to macro_build to
1854 pass new argument for i, j and o cases.
1855 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
1856 special handling when generating SVR4 PIC code.

2190 default is to assume production environment, and reject configs
2191 still being worked on. Mark Elf configurations (except sparc and
2192 i386) as developmental. Deleted cases matching some generic names
2193 in favor of more specific names. (E.g., when we get Alpha

2210 through inclusion of tc-hppa.h. Delete all forward declarations
2211 for functions only used within tc-hppa.c, likewise for structures,
2212 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2213 conditional code in a few small places.
2215 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group

2218 conditional code -- try to group conditional code together
2219 into a few places. Make all functions and variables which
2220 are only used within tc-hppa.c static. PARAMize all functions.
2221 Add comments to functions. Delete unused functions, variables,
2222 #defines, etc. Delete unused members within structures. Delete
2223 ldil;ble hacks -- it is believed they were installed to work
2224 around old gas bugs. Avoid using mixed case for local
2225 functions, variables, and structures. Fix formatting problems
2226 not found by GNU-indent. Add FIXME notices for things which
2227 should be worked on the near future. Delete lots of old
2228 useless (1.36 PA-SOM) code.

2303 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2304 ELF, since the ELF object format does not have these type of
2305 relocations. Change the abort into as as_bad and return
2306 BFD_RELOC_NONE to silence compiler warnings.
2307 (md_assemble): Keep track of the instruction size. Allow white
2308 space between the $ and the constant for compatibility with older
2309 gases and other assemblers.

3305 * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
3306 are also magic, and have special default flag settings.
3307 (obj_elf_frob_symbol): Since the return value from this function
3308 isn't used, don't bother calling obj_elf_write_symbol_p, since it
3309 doesn't accomplish anything else.

3321 undefined_section for the return value.
3323 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
3324 pseudo-op with a poc_handler field of NULL, ignore it and treat it

3343 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
3344 *-*-solaris case, and move to before *-sysv* case that wants to
3345 set obj_format to coff.

3371 * Extensive changes to permit symbols to contain any expression
3372 type and to delay the computation of the expression until the
3373 value is actually needed. This permits setting symbols to values
3374 calculated based on object code size. Expressions were changed to
3375 no longer be in a section, to stop the overloading of segment and
3376 expression type that previously occurred.
3378 * as.c (big_section, pass1_section, diff_section, absent_section):
3380 (expr_section): Added (used for dummy symbols which hold

3464 (previous_section, previous_subsection): New vars.
3465 (obj_elf_section): Save current place in case DWARF code wants us
3466 to pop back to it. Handle unquoted section name as well as quoted
3467 section name. Don't crash on invalid strings.
3468 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
3471 * config/obj-elf.h: Don't include struc-symbol.h.

3580 sy_resolved and sy_resolving single bit fields.
3581 * symbols.c (symbol_new): Don't initialize sy_forward field.

4745 lines; I don't think that can be done portably.
4746 * config/tc-mips.c (macro): Use $AT if target register is zero in
4747 load instruction, which it can be for a floating point load.

4873 * read.c (s_ignore): Don't declare is_end_of_line. It's
4874 redundant, and triggers a VMS gcc compiler bug.
4876 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4877 current segment as an argument. (Ignored in all cases but VMS.)
4878 All callers and definitions changed.

5193 From Eric Youngdale:
5194 (operand): Set X_add_number field for floating-point numbers.
5195 (operand): Treat zero byte as end-of-operand.
5197 * configure.in (per-target): Look for with_bfd_assembler option.
5198 For now, only accept "no", until the merge is done.
5200 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5201 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5202 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5203 * read.c: Finish conversion to S_* macros in the VMS only
5204 parts of the program. Add "const" modifier to hex_value.
5205 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5207 * expr.c: Add "const" modifier to hex_value.
5208 * symbols.c: Finish conversion to S_* macros in the VMS only
5209 parts of the program. Add "const" modifier to
5210 md_[long,short]_jump_size. Remove declaration of const_flag
5211 (which will be declared in obj-vms.h).
5212 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5213 Fix arguments to VMS_write_object_file.
5214 * config-gas.com: New file. Script for VMS systems to set up the
5215 configuration to build gas for VMS, and create config.status.
5216 * make-gas.com: Redone to work with new scheme.
5217 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5219 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5220 will swap bytes if needed on a big endian system. Use throughout
5222 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5223 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5224 types of malformed stabs. Change parsing algorithm so that we are
5225 more certain of having all of the information that we need on hand.
5226 * obj-vms.c (final_forward_reference): New function, used to help
5227 resolve the data types of as many struct elements as possible
5228 when some part of the struct is not fully defined by the compiler.
5229 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5231 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5232 as symbols as well in the object file. Look for external functions
5233 that start with "__vt.", and turn them into variables, since the
5234 g++ compiler is incapable of doing this.
5235 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5237 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5238 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5239 have the name of the source file yet.
5240 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5242 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5244 * read.c (s_data): Always use "data_section", since it'll map to
5245 SEG_DATA or SEG_E1 if needed.
5246 (s_lcomm): Likewise with bss_section.
5247 (s_fill): Use memset, not bzero.
5249 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5265 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
5266 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

5270 (section_alignment): Declare only if not BFD_ASSEMBLER.
5271 (big_section, reg_section, pass1_section, diff_section,
5272 absent_section, text_section, data_section, bss_section): If
5273 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5274 mapping to segT enum values.
5275 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5276 if these are used or defined, if BFD_ASSEMBLER.
5277 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5278 subseg_new split into two functions.
5279 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5281 * as.h (volatile): Don't define if already defined.
5282 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5284 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5285 declare with format attribute for -Wformat checking.
5287 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5289 * app.c, config/tc-*.c: Don't include read.h, since it is already
5292 * These are based on patches from Minh Tran-le
5293 <mtranle@paris.intellicorp.com>.
5294 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5295 obj_format coffbfd and gas_target i386coff for target.
5296 (i[34]86-*-isc*): New host (uses sysv).
5297 * config/i386aix.mt: Removed (no longer used).
5298 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5300 (LDFLAGS): Added, defined as -shlib.
5301 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5302 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5303 (DOT_LABEL_PREFIX): Define.
5304 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5305 name rather than L0\001.
5306 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5308 * symbols.c, symbols.h (local_bss_counter): Removed.
5309 * write.c (write_object_file): bss no longer uses
5310 local_bss_counter. Pass correct data and bss size to
5311 VMS_write_object_file.

5316 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
5317 (size_section): Restored sanity check.
5318 (do_relocs_for): Base section address on s_paddr rather than
5319 computing it. Adjust a29k R_IHIHALF special case to account for
5320 section paddr (used to require paddr to be zero). If there are no
5321 reclos, set s_relptr to 0. Set relocation size in object_headers.
5322 (fill_section): Always set s_vaddr here, removing
5323 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5324 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5325 Set STYP_INFO for .comment.
5326 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5327 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5329 H_{SET,GET}_* macros.
5330 (do_linenos_for): Set lineno size in object_headers.
5331 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5332 set s_vaddr here. If string_byte_count remains 4, set it back to
5333 0, and only write strings out if there are some. Call
5334 fill_section before do_relocs_for and do_linenos_for.
5335 (obj_coff_section): Handle optional quoted second argument giving
5336 section characteristics.
5337 (obj_coff_bss): Added to handle .bss.
5338 (obj_coff_ident): Added to handle .ident (puts string in .comment

5358 (do_scrub_next_char): For \", return " not '.
5359 (symbol_chars): Now const.
5361 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5362 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5364 * config/obj-coff.h: Don't use #elif.
5366 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5367 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

5393 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5394 using ZERO_BASED_SEGMENTS.
5395 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5396 never set segment address for SEG_E2 (.bss) and don't write out
5397 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5398 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5399 definitions, and don't merge tags with non-tags. Check for .bf
5400 rather than just checking whether the second character is b and
5401 the third character is f.
5402 (obj_coff_val): gcc can generate values which we don't handle
5403 correctly; discard information for now, since it only affects the
5404 debugging information.
5405 (tag_find_or_name): Don't insert tags in the symbol table.
5406 (yank_symbols): Don't merge labels.
5407 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5667 * tc-z8k.c: lots of bug fixes
5669 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5671 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5672 #elif, since it is not supported by old compilers.
5673 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5674 couple of expressions in tc-m68k.c.
5676 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5678 * read.c (cons): If NO_RELOC is defined, use it.
5680 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5682 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5684 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5685 local labels to start with a .) and set REGISTER_PREFIX to %.
5686 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5688 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5699 * listing.c (debugging_pseudo): Add stabs and stabn as things to
5702 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5704 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5705 sections starting from zero, rather than making them consecutive.
5706 This makes subsequent reloc calculations easier, esp if the object
5707 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5708 allocate lcomm in .data rather than in .bss. It seems that some
5709 tools can't cope with a non-zero sized bss before linkage.
5711 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5713 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
5714 throughout. That enum no longer means what we thought it meant.

5717 "-mno-688[58]1" options.
5719 * tc-m68k.c: Added CPU32 support.

5730 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
5732 * Makefile.in (install): if $(tooldir) exists, install as in
5735 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5737 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5738 .word is < -32768 or > 32767. The -J flag causes the error to be
5739 ignored. This is to catch over-sized switches generated by gcc on
5740 systems which don't support the broken .word hack.
5741 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5742 write.c (fixup_segment): check for signed .word overflow if
5743 WARN_SIGNED_OVERFLOW_WORD.
5745 * write.c (fixup_segment): fixed missing parens in expression
5746 checking for byte or word overflow.
5748 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
5749 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
5750 WARN_SIGNED_OVERFLOW_WORD.

5760 * tc-i386.h : new coff defines
5762 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5764 * input-scrub.c (input_scrub_push): call input_file_begin, not
5766 messages.c (as_perror): print ": " between the passed in error and
5767 the strerror, like perror does.
5769 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
5771 * Makefile.in: use gas_target instead of modifying target_cpu.
5772 From Steve Chamberlain:
5773 Makefile.in: Handle m68*-*-coff*.
5774 read.c, read.h: add mult argument to s_space
5776 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5777 Motorola and MIT syntax; gas can now assemble either type of
5779 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5785 (write_object_file) call fixup_mdeps
5786 (fixup_segment) set fx_subsy to 0.
5787 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5789 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5792 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5794 * Makefile.in (LIBS): Include opcode library.

5817 little endian byte order (used to use endianness of host).
5819 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5821 * config/tc-m68k.c (init_table): Now const. Always include 68851
5822 data, so that "bc" is available to 68040 cache instructions.
5823 Added "tt0", "tt1", and 68ec030 variants.
5824 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5825 (enum _register): Added TT0, TT1.
5826 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5827 line number correctly in "internal error" messages. Don't print
5828 architecture-mismatch message for operand errors.
5830 From Colin Smith (colin@wrs.com):
5831 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5832 than install_operand.

5853 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5854 has already been formatted (but may still contain %-characters).
5857 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5859 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5860 written with indirection on the last two operands, which can be
5861 either data or address registers. Added a new operand type 'r'
5862 which accepts either register type. Added '(' to notend stuff in
5863 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5882 their not having symbols associated.
5884 * tc-i960.c (norelax, instrument_branches): Default initializer is
5886 (linkrelax): Delete variable definition.

6156 * symbols.c: remove local_labels_dollar, replace with a function
6157 interface for a sparse array. All users adjusted.
6159 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
6161 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6163 * doc/Makefile.in: commented out line for building as-all.texinfo.
6166 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
6168 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
6170 * Makefile.in: added check target.
6172 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6174 * Makefile.in: added tooldir and program_prefix.
6176 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
6178 * write.{c,h} (fix_new): Make these declarations consistent.
6180 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
6182 * Makefile.in (strerror.o): Add rule so that broken Sun make can
6185 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6187 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6189 * expr.c (operand): if can't work out what sort of operand it is,
6190 then look through FLT_CHARS for a hint.
6192 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6194 * Makefile.in, configure.in: removed traces of namesubdir,
6195 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6196 copyrights to '92, changed some from Cygnus to FSF.
6198 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6199 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6200 copyrights to '92, changed some from Cygnus to FSF.
6202 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6204 * expr.c: If an expression is single comma, then return with
6205 SEG_ABSENT rather than an error - since the sparc front end does
6206 really strange things with things like fbge,a
6208 * as.h: include bfd.h if using many sections
6209 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6210 local labels didn't work.
6211 * listing.c (list_symbol_table): don't core dump when there's no
6213 * write.c, write.h: call fix_new with the right number of args on
6215 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6218 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6220 * app.c: MRI compatibility - allow single quote to start a string.
6221 * as.c: fix typo recently introduced.
6222 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6223 * expr.c: Much rewriting, to accomodate MRI syntax for
6224 expressions. Also easier to read now.
6225 * listing.c: Put back defuns
6226 * read.c: modified to accept MRI syntax, put back listing pseudo
6227 ops so that an assembler built with NO_LISTING ignores list ops
6229 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6230 machine is a SPARC or a 29K.
6231 * config/obj-aout.c: added s_sect pseudo op
6232 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6233 fill in the timestamp.
6234 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6235 anymore, define all the relocs which the tc-<x> bit will use so we
6236 can translate from them to the coff types.
6237 * config/tc-a29k.c: reloc_type isn't ane enum any more
6238 * config/tc-m68k.c: Added NO_RELOC definition.
6240 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6242 * Makefile.in: put header files before C source for TAGS; remove
6243 references to non-existent syscalls.h.
6245 * read.c, write.c subsegs.c: back out the .bss changes.
6247 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6249 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6253 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6255 * symbols.c (local_label_name): symbols now start with ^A.
6257 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6258 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6259 generate these sections. .align: will use NOP_OPCODE or 0
6260 for padding. This is just for being nice to the
6263 * expr.c (operand): changed to generate local label "\001L0"
6264 starting with a ^A so that it is recognized as a local label.
6266 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6268 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6269 i/o opcodes - inb, inw, outb and outw. string manipulation with
6270 att syntax - scmp, slod, smov, ssca, ssto.
6272 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6273 to just after .file .
6275 In obj_crawl_symbol_chain() where it tries to put the external
6276 symbols apart, with the condition:
6277 (!S_IS_DEFINED(symbolP) &&
6278 !S_IS_DEBUG(symbolP) &&
6279 !SF_GET_STATICS(symbolP))
6280 it was moving too many symbols out. So I switch it back to the
6282 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6284 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6285 so that we don't use the F_RELFLG which make the linker complain
6286 that somebody has stripped the relocation info.
6288 Also, the AIX ld program require that the relocation table
6289 is sorted by r_vaddr like the standard ATT assembler does.
6291 [he also changed the sizeof(struct ...)'s into the coff
6292 style FOOSZ macros. I'm not sure this is right, but I can't
6293 remember why. xoxorich.]
6295 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6297 * Makefile.in, configure.in, doc: use the doc. Build it, install
6300 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6302 * read.c: white space and comments only.
6304 * configure.in: use the new atof-ns32.c for ns32k.
6306 * write.c: comment change only.
6308 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6309 aren't yet integrated.
6311 * tc-i860.[hc]: blew off the dust. Something must still be done
6312 about conflicting relocation types.
6314 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6317 * tc-i960.c, tc-sparc.c: white space and comments only.
6319 * tc-a29k.h: delete duplicate macro definition.
6321 * new file atof-ns32k.c copied from hack's last unreleased gas.
6323 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6325 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6328 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6329 ChangeLog's prior to this are sketchy at best. I have logs.
6330 They just aren't ChangeLogs.
6334 version-control: never
