1855 BFD_RELOC_MIPS_GPREL. Added new case a.
1856 (set_at, load_register, macro): Changed calls to macro_build to
1857 pass new argument for i, j and o cases.
1858 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
1859 special handling when generating SVR4 PIC code.

2193 default is to assume production environment, and reject configs
2194 still being worked on. Mark Elf configurations (except sparc and
2195 i386) as developmental. Deleted cases matching some generic names
2196 in favor of more specific names. (E.g., when we get Alpha

2213 through inclusion of tc-hppa.h. Delete all forward declarations
2214 for functions only used within tc-hppa.c, likewise for structures,
2215 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2216 conditional code in a few small places.

2221 conditional code -- try to group conditional code together
2222 into a few places. Make all functions and variables which
2223 are only used within tc-hppa.c static. PARAMize all functions.
2224 Add comments to functions. Delete unused functions, variables,
2225 #defines, etc. Delete unused members within structures. Delete
2226 ldil;ble hacks -- it is believed they were installed to work
2227 around old gas bugs. Avoid using mixed case for local
2228 functions, variables, and structures. Fix formatting problems
2229 not found by GNU-indent. Add FIXME notices for things which
2230 should be worked on the near future. Delete lots of old
2231 useless (1.36 PA-SOM) code.

2306 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2307 ELF, since the ELF object format does not have these type of
2308 relocations. Change the abort into as as_bad and return
2309 BFD_RELOC_NONE to silence compiler warnings.
2310 (md_assemble): Keep track of the instruction size. Allow white
2311 space between the $ and the constant for compatibility with older
2312 gases and other assemblers.

3308 * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
3309 are also magic, and have special default flag settings.
3310 (obj_elf_frob_symbol): Since the return value from this function
3311 isn't used, don't bother calling obj_elf_write_symbol_p, since it
3312 doesn't accomplish anything else.

3324 undefined_section for the return value.
3326 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
3327 pseudo-op with a poc_handler field of NULL, ignore it and treat it

3344 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
3345 case to set obj_format=elf. Must go before i386-*-sysv* case that
3346 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
3347 *-*-solaris case, and move to before *-sysv* case that wants to
3348 set obj_format to coff.

3374 * Extensive changes to permit symbols to contain any expression
3375 type and to delay the computation of the expression until the
3376 value is actually needed. This permits setting symbols to values
3377 calculated based on object code size. Expressions were changed to
3378 no longer be in a section, to stop the overloading of segment and
3379 expression type that previously occurred.
3381 * as.c (big_section, pass1_section, diff_section, absent_section):
3383 (expr_section): Added (used for dummy symbols which hold

3467 (previous_section, previous_subsection): New vars.
3468 (obj_elf_section): Save current place in case DWARF code wants us
3469 to pop back to it. Handle unquoted section name as well as quoted
3470 section name. Don't crash on invalid strings.
3471 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
3474 * config/obj-elf.h: Don't include struc-symbol.h.

3583 sy_resolved and sy_resolving single bit fields.
3584 * symbols.c (symbol_new): Don't initialize sy_forward field.

4746 dropping a space immediately following an identifier.
4747 * expr.c, write.c: Rewrote assert expressions to not use multiple
4748 lines; I don't think that can be done portably.
4749 * config/tc-mips.c (macro): Use $AT if target register is zero in
4750 load instruction, which it can be for a floating point load.

4824 prototypes for all static functions. Moved existing minimal
4825 debugging format support info #ifndef OBJ_ECOFF blocks.

4874 * make-gas.com: Find obstack.obj if it's not in the current
4876 * read.c (s_ignore): Don't declare is_end_of_line. It's
4877 redundant, and triggers a VMS gcc compiler bug.
4879 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4880 current segment as an argument. (Ignored in all cases but VMS.)
4881 All callers and definitions changed.

5196 From Eric Youngdale:
5197 (operand): Set X_add_number field for floating-point numbers.
5198 (operand): Treat zero byte as end-of-operand.
5200 * configure.in (per-target): Look for with_bfd_assembler option.
5201 For now, only accept "no", until the merge is done.
5203 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5204 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5205 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5206 * read.c: Finish conversion to S_* macros in the VMS only
5207 parts of the program. Add "const" modifier to hex_value.
5208 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5210 * expr.c: Add "const" modifier to hex_value.
5211 * symbols.c: Finish conversion to S_* macros in the VMS only
5212 parts of the program. Add "const" modifier to
5213 md_[long,short]_jump_size. Remove declaration of const_flag
5214 (which will be declared in obj-vms.h).
5215 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5216 Fix arguments to VMS_write_object_file.
5217 * config-gas.com: New file. Script for VMS systems to set up the
5218 configuration to build gas for VMS, and create config.status.
5219 * make-gas.com: Redone to work with new scheme.
5220 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5222 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5223 will swap bytes if needed on a big endian system. Use throughout
5225 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5226 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5227 types of malformed stabs. Change parsing algorithm so that we are
5228 more certain of having all of the information that we need on hand.
5229 * obj-vms.c (final_forward_reference): New function, used to help
5230 resolve the data types of as many struct elements as possible
5231 when some part of the struct is not fully defined by the compiler.
5232 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5234 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5235 as symbols as well in the object file. Look for external functions
5236 that start with "__vt.", and turn them into variables, since the
5237 g++ compiler is incapable of doing this.
5238 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5240 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5241 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5242 have the name of the source file yet.
5243 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5245 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5247 * read.c (s_data): Always use "data_section", since it'll map to
5248 SEG_DATA or SEG_E1 if needed.
5249 (s_lcomm): Likewise with bss_section.
5250 (s_fill): Use memset, not bzero.
5252 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5268 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
5269 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

5273 (section_alignment): Declare only if not BFD_ASSEMBLER.
5274 (big_section, reg_section, pass1_section, diff_section,
5275 absent_section, text_section, data_section, bss_section): If
5276 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5277 mapping to segT enum values.
5278 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5279 if these are used or defined, if BFD_ASSEMBLER.
5280 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5281 subseg_new split into two functions.
5282 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5284 * as.h (volatile): Don't define if already defined.
5285 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5287 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5288 declare with format attribute for -Wformat checking.
5290 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5292 * app.c, config/tc-*.c: Don't include read.h, since it is already
5295 * These are based on patches from Minh Tran-le
5296 <mtranle@paris.intellicorp.com>.
5297 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5298 obj_format coffbfd and gas_target i386coff for target.
5299 (i[34]86-*-isc*): New host (uses sysv).
5300 * config/i386aix.mt: Removed (no longer used).
5301 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5303 (LDFLAGS): Added, defined as -shlib.
5304 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5305 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5306 (DOT_LABEL_PREFIX): Define.
5307 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5308 name rather than L0\001.
5309 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5311 * symbols.c, symbols.h (local_bss_counter): Removed.
5312 * write.c (write_object_file): bss no longer uses

5320 (size_section): Restored sanity check.
5321 (do_relocs_for): Base section address on s_paddr rather than
5322 computing it. Adjust a29k R_IHIHALF special case to account for
5323 section paddr (used to require paddr to be zero). If there are no
5324 reclos, set s_relptr to 0. Set relocation size in object_headers.
5325 (fill_section): Always set s_vaddr here, removing
5326 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5327 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5328 Set STYP_INFO for .comment.

5332 H_{SET,GET}_* macros.
5333 (do_linenos_for): Set lineno size in object_headers.
5334 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5335 set s_vaddr here. If string_byte_count remains 4, set it back to
5336 0, and only write strings out if there are some. Call
5337 fill_section before do_relocs_for and do_linenos_for.
5338 (obj_coff_section): Handle optional quoted second argument giving
5339 section characteristics.
5340 (obj_coff_bss): Added to handle .bss.
5341 (obj_coff_ident): Added to handle .ident (puts string in .comment

5361 (do_scrub_next_char): For \", return " not '.
5362 (symbol_chars): Now const.
5364 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5365 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5367 * config/obj-coff.h: Don't use #elif.
5369 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5370 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

5396 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5397 using ZERO_BASED_SEGMENTS.
5398 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5399 never set segment address for SEG_E2 (.bss) and don't write out
5400 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5401 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5402 definitions, and don't merge tags with non-tags. Check for .bf
5403 rather than just checking whether the second character is b and
5404 the third character is f.
5405 (obj_coff_val): gcc can generate values which we don't handle
5406 correctly; discard information for now, since it only affects the
5407 debugging information.
5408 (tag_find_or_name): Don't insert tags in the symbol table.
5409 (yank_symbols): Don't merge labels.
5410 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5670 * tc-z8k.c: lots of bug fixes
5672 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5674 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5675 #elif, since it is not supported by old compilers.
5676 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5677 couple of expressions in tc-m68k.c.
5679 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5681 * read.c (cons): If NO_RELOC is defined, use it.
5683 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5685 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5687 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5688 local labels to start with a .) and set REGISTER_PREFIX to %.
5689 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5691 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5702 * listing.c (debugging_pseudo): Add stabs and stabn as things to
5705 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5707 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5708 sections starting from zero, rather than making them consecutive.
5709 This makes subsequent reloc calculations easier, esp if the object
5710 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5711 allocate lcomm in .data rather than in .bss. It seems that some
5712 tools can't cope with a non-zero sized bss before linkage.
5714 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5716 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
5717 throughout. That enum no longer means what we thought it meant.

5720 "-mno-688[58]1" options.
5722 * tc-m68k.c: Added CPU32 support.

5735 * Makefile.in (install): if $(tooldir) exists, install as in
5738 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5740 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5741 .word is < -32768 or > 32767. The -J flag causes the error to be
5742 ignored. This is to catch over-sized switches generated by gcc on
5743 systems which don't support the broken .word hack.
5744 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5745 write.c (fixup_segment): check for signed .word overflow if
5746 WARN_SIGNED_OVERFLOW_WORD.
5748 * write.c (fixup_segment): fixed missing parens in expression
5749 checking for byte or word overflow.
5751 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
5752 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
5753 WARN_SIGNED_OVERFLOW_WORD.

5765 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5767 * input-scrub.c (input_scrub_push): call input_file_begin, not
5769 messages.c (as_perror): print ": " between the passed in error and
5770 the strerror, like perror does.
5772 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
5774 * Makefile.in: use gas_target instead of modifying target_cpu.
5775 From Steve Chamberlain:
5776 Makefile.in: Handle m68*-*-coff*.
5777 read.c, read.h: add mult argument to s_space
5779 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5780 Motorola and MIT syntax; gas can now assemble either type of
5782 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5788 (write_object_file) call fixup_mdeps
5789 (fixup_segment) set fx_subsy to 0.
5790 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5792 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5795 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5797 * Makefile.in (LIBS): Include opcode library.

5820 little endian byte order (used to use endianness of host).
5822 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5824 * config/tc-m68k.c (init_table): Now const. Always include 68851
5825 data, so that "bc" is available to 68040 cache instructions.
5826 Added "tt0", "tt1", and 68ec030 variants.
5827 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5828 (enum _register): Added TT0, TT1.
5829 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5830 line number correctly in "internal error" messages. Don't print
5831 architecture-mismatch message for operand errors.
5833 From Colin Smith (colin@wrs.com):
5834 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5835 than install_operand.

5856 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5857 has already been formatted (but may still contain %-characters).
5860 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5862 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5863 written with indirection on the last two operands, which can be
5864 either data or address registers. Added a new operand type 'r'
5865 which accepts either register type. Added '(' to notend stuff in
5866 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6159 * symbols.c: remove local_labels_dollar, replace with a function
6160 interface for a sparse array. All users adjusted.
6162 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
6164 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6166 * doc/Makefile.in: commented out line for building as-all.texinfo.
6169 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
6171 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
6173 * Makefile.in: added check target.
6175 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6177 * Makefile.in: added tooldir and program_prefix.
6179 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
6181 * write.{c,h} (fix_new): Make these declarations consistent.
6183 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
6185 * Makefile.in (strerror.o): Add rule so that broken Sun make can
6188 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6190 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6192 * expr.c (operand): if can't work out what sort of operand it is,
6193 then look through FLT_CHARS for a hint.
6195 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6197 * Makefile.in, configure.in: removed traces of namesubdir,
6198 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6199 copyrights to '92, changed some from Cygnus to FSF.
6201 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6202 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6203 copyrights to '92, changed some from Cygnus to FSF.
6205 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6207 * expr.c: If an expression is single comma, then return with
6208 SEG_ABSENT rather than an error - since the sparc front end does
6209 really strange things with things like fbge,a
6211 * as.h: include bfd.h if using many sections
6212 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6213 local labels didn't work.
6214 * listing.c (list_symbol_table): don't core dump when there's no
6216 * write.c, write.h: call fix_new with the right number of args on
6218 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6221 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6223 * app.c: MRI compatibility - allow single quote to start a string.
6224 * as.c: fix typo recently introduced.
6225 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6226 * expr.c: Much rewriting, to accomodate MRI syntax for
6227 expressions. Also easier to read now.
6228 * listing.c: Put back defuns
6229 * read.c: modified to accept MRI syntax, put back listing pseudo
6230 ops so that an assembler built with NO_LISTING ignores list ops
6232 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6233 machine is a SPARC or a 29K.
6234 * config/obj-aout.c: added s_sect pseudo op
6235 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6236 fill in the timestamp.
6237 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6238 anymore, define all the relocs which the tc-<x> bit will use so we
6239 can translate from them to the coff types.
6240 * config/tc-a29k.c: reloc_type isn't ane enum any more
6241 * config/tc-m68k.c: Added NO_RELOC definition.
6243 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6245 * Makefile.in: put header files before C source for TAGS; remove
6246 references to non-existent syscalls.h.
6248 * read.c, write.c subsegs.c: back out the .bss changes.
6250 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6252 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6256 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6258 * symbols.c (local_label_name): symbols now start with ^A.
6260 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6261 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6262 generate these sections. .align: will use NOP_OPCODE or 0
6263 for padding. This is just for being nice to the
6266 * expr.c (operand): changed to generate local label "\001L0"
6267 starting with a ^A so that it is recognized as a local label.
6269 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6271 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6272 i/o opcodes - inb, inw, outb and outw. string manipulation with
6273 att syntax - scmp, slod, smov, ssca, ssto.
6275 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6276 to just after .file .
6278 In obj_crawl_symbol_chain() where it tries to put the external
6279 symbols apart, with the condition:
6280 (!S_IS_DEFINED(symbolP) &&
6281 !S_IS_DEBUG(symbolP) &&
6282 !SF_GET_STATICS(symbolP))
6283 it was moving too many symbols out. So I switch it back to the
6285 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6287 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6288 so that we don't use the F_RELFLG which make the linker complain
6289 that somebody has stripped the relocation info.
6291 Also, the AIX ld program require that the relocation table
6292 is sorted by r_vaddr like the standard ATT assembler does.
6294 [he also changed the sizeof(struct ...)'s into the coff
6295 style FOOSZ macros. I'm not sure this is right, but I can't
6296 remember why. xoxorich.]
6298 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6300 * Makefile.in, configure.in, doc: use the doc. Build it, install
6303 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6305 * read.c: white space and comments only.
6307 * configure.in: use the new atof-ns32.c for ns32k.
6309 * write.c: comment change only.
6311 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6312 aren't yet integrated.
6314 * tc-i860.[hc]: blew off the dust. Something must still be done
6315 about conflicting relocation types.
6317 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6320 * tc-i960.c, tc-sparc.c: white space and comments only.
6322 * tc-a29k.h: delete duplicate macro definition.
6324 * new file atof-ns32k.c copied from hack's last unreleased gas.
6326 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6328 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6331 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6332 ChangeLog's prior to this are sketchy at best. I have logs.
6333 They just aren't ChangeLogs.
6337 version-control: never
