1940 * config/tc-hppa.c: Eliminate all uses of fx_addnumber.
1941 (tc_gen_reloc): Simplify. It's no longer necessary to set a
1942 reloc's addend field to zero for function symbols.
1943 (md_apply_fix): Simplify. For fixups which will require a SOM
1944 reloc, just clear out the necessary bits in the output file.

1964 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
1965 it's better to use the one in libiberty.
1967 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1969 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
1970 change; it breaks the rs6000 support, and doesn't seem to be

1984 used to be added by coff_add_linesym, removed Oct 7.
1985 (coff_adjust_section_syms): Ignore sections with no seginfo.
1987 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1989 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a
1990 "stage" symlink to the appropriate stage* directory, and use it
1991 instead in the -B options.
1992 (comparison): Revert yesterday's change.

1999 Tue Oct 11 15:24:00 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
2001 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
2002 for an embedded PIC switch expression, since the definition of
2003 S_IS_LOCAL was changed.

2007 * Makefile.in (comparison): When comparing as.new or gasp.new, try
2008 running the binary through sed to avoid differences due to

2011 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
2013 ELF symbol size handling, based on code from Eric Youngdale:
2014 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an

2021 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
2023 (obj_elf_size): Deleted unused code. If size is non-reducible
2024 expression, allocate some storage for the sy_obj field and copy
2026 (elf_frob_symbol): New function. Computes sizes, calls
2027 ecoff_frob_symbol if appropriate.
2029 * write.c (fixup_segment): For i386 elf and coff (for now), don't

2078 (diststuff): New target; builds DISTSTUFF.
2079 (realclean): Separate target, depend on clean and distclean, then
2081 * make-gas.com: Deleted.

2084 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
2086 (i386_operand): Don't look up section symbol for
2088 (reloc): Always permit return of 8- and 16-bit relocation types.
2089 Add a space after "pc-relative" in the error message.
2090 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
2091 BFD_RELOC_386_GOTOFF relocs.

2102 referring to PLT entries.
2103 * write.c (fix_new_internal): Initialize fx_plt to zero.
2104 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
2105 Don't adjust fx_offset by frag address, since S_GET_VALUE now
2106 includes the frag address.
2107 (fixup_segment): Changed local var PCREL to type int, added PLT.
2108 If PC-relative fixup refers to a PLT entry for a symbol in the
2109 current section, don't reduce it.

2133 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2135 * configure.in: Set bfd_gas for all sparc targets in one place,
2136 instead of separately for each. Correctly handle user-supplied
2137 "--enable-bfd-gas" option.
2139 * gdbinit.in: Move "break abort" to end, in case gdb complains.
2141 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
2144 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
2145 processing if add_symbol is undefined or in expr_section.

2149 (indent_level): No longer static.
2150 (print_symbol_value_1): Don't print frag address if it matches

2154 (print_expr_1): Fix whitespace before printing X_add_number.
2156 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
2157 not symbol_new, for symbols holding expression values.
2158 * expr.h (make_expr_symbol): Move declaration here.
2159 * write.c (fix_new_exp): Handle O_add by creating an
2160 expression-valued symbol, and calling fix_new_exp recursively.
2161 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
2162 undefined symbol and a constant, fold the constant into the fixup,
2163 and refer to the undefined symbol directly. Then process the
2164 fixup again from scratch.
2165 (write_object_file): Before calling adjust_reloc_syms, make a pass
2166 through the symbol list trying to resolve values.
2168 * write.c (print_fixup): New routine, for debugging.
2169 (write_relocs): Call bfd_install_relocation. Deleted various
2170 hacks for working around problems with bfd_perform_relocation.
2172 * Makefile.in (VERSION): Update to 2.4.90.
2174 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

2178 * config/tc-mips.c: Include subsegs.h.
2179 (md_apply_fix): If an unconditional b or bal overflows, and we are
2180 not assembling PIC code, replace it with a j or jal.
2182 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
2183 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
2185 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2187 * write.c (write_relocs): Add file name and line number to
2188 as_fatal calls. Handle bfd_reloc_overflow case specifically when
2189 RELOC_EXPANSION_POSSIBLE.
2191 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2193 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
2194 here. Use them for deciding which PRINTF*LIKE macro definitions
2196 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
2197 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
2198 default definitions matching what we were doing before.
2199 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
2200 always use the varargs form if not using stdarg. It's safe to
2201 always use vfprintf, because libiberty will provide it if the
2202 native system doesn't. Also, always make format be const.
2203 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

2218 (listing_newline): Check filename as well as line number when
2219 deciding whether to record it.
2220 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
2221 false (if defined) as well as checking for reg_section.
2222 (listing_listing): Iterate fetching lines while line number is too
2223 low, and we haven't run off the end of the input file.
2225 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
2227 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
2229 * ecoff.c (ecoff_generate_asm_lineno): check if
2230 current_stabs_filename is NULL before strcmp.
2231 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
2234 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2236 * config/ho-*.h: Now-unused files deleted.
2238 * symbols.c (copy_symbol_attributes): New function. Copies BFD
2239 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
2240 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
2241 zero. Don't call obj_frob_forward_symbol.
2242 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
2243 X_add_number is zero.
2244 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
2246 * config/tc-i960.c: Lots of whitespace, comment reformatting,
2248 (strchr): Don't declare.
2249 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
2250 md_estimate_size_before_relax, md_ri_to_chars,
2251 md_create_short_jump, md_create_long_jump.
2252 (brtab_emit): Use data_section, not SEG_DATA.
2254 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2256 * config/vms-conf.h: new file, manually derived from conf.in.
2257 * config-gas.com: use it, and eliminate obsolete "host.h".

2261 * config/tc-ppc.c (ppc_current_block): New static variable.
2262 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
2263 ppc_current_block. Don't move around any stab symbol, just those

2266 (ppc_es): Clear ppc_current_block.
2267 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
2268 from the csect of the enclosing block.
2270 * config/tc-mips.c (insns_since_cache_access): Remove.
2271 (append_insn): Remove setting of insns_since_cache_access, and
2272 special 4600 handling; it turns out not to be required.
2274 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2276 * config/tc-mips.c (md_shortopts): Remove E.
2277 (md_longopts): Add EB and EL.
2278 (md_parse_option): Handle -EB and -EL as separate options, rather
2279 than as a single -E option with an argument.

2283 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
2284 involving global symbols too.
2286 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2288 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
2290 * configure.in: Test for remove, not delete. Fix cross-assembler
2292 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
2295 * read.c (pseudo_set, case O_symbol): If
2296 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
2297 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.

2300 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
2302 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
2303 many others): new macros; values obtained from "DSTRECRDS.SDL".
2304 * config/obj-vms.h (various): use them.
2305 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
2306 representation (only enum bitfields can avoid being bitstrings).
2307 (bitfield_suffix, setup_basic_type): new routines.
2308 (VMS_typedef_parse): use them. Now recognize bitfields of all
2309 integral types, not just type `int'. Caveat: the representation
2310 used for bitfields still does not work for objects placed in
2311 registers, and gcc's optimizer sometimes puts small structs there.
2313 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2315 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
2316 bit from const_flag.
2317 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
2318 (tc_frob_label): define this to call vms_check_for_special_label,
2319 and declare the latter.
2320 * config/obj-vms.c (vax_g_doubles): declare this file-scope
2322 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
2323 (vms_check_for_special_label): new routine (tc_frob_label).
2324 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
2325 and `gcc2_compiled.' labels; they won't reach here any more.
2326 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
2327 double', use `vax_g_doubles' flag to select type of double.
2328 (VMS_write_object_file) [traceback setup]: don't pass symbols
2329 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
2330 and TBT_Routine_End functions.

2334 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
2335 S_GET_VALUE() to avoid many repeated function calls.
2336 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
2337 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
2338 gets requested. [All the HACK_DEC_C_STARTUP code appears to
2339 be obsolete; gcc does it automatically for vms target. It's
2340 also misnamed, because it is for the "VAX C" run-time library,
2341 not the newer "DEC C" one which has much different startup code.]
2342 {various}: use `S_SET_xxx(symbol,new_value)' rather than
2343 `S_GET_xxx(symbol) = new_value'.
2345 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2347 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
2348 not &bfd_abs_section.
2350 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2352 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
2354 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
2356 * expr.c (expr): Don't reduce the difference of two symbols in the
2357 same frag if the symbols are not in normal sections.
2359 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
2360 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
2361 (obj_attach_unwind_info): Do not define. Not needed anymore.
2362 * config/tc-hppa.c: Delete whitespace at EOL.
2363 (struct hppa_fix_struct): Delete fx_unwind field and all references.
2364 (fix_new_hppa): Last arg is now a pointer to an int. Do not
2365 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT

3328 (DBG_S_C_REAL8_G, DBG_S_C_COMPLX8_G): G_float versions of
3329 REAL8 and COMPLX8; not used yet, because gcc outputs the same
3330 .stabs for `double' regardless of whether `-mg' is used.

3342 $8,%hi(foo); lw $8,%lo(foo)($8)'' work correctly.
3344 Mon Jun 13 12:08:52 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3346 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
3347 to put a common symbol in a set.

3353 OBJ_BOUT if not BFD_ASSEMBLER.
3354 * config/aout_gnu.h (N_WEAKU, N_WEAKA, N_WEAKT, N_WEAKD, N_WEAKB):
3355 Define as in ../include/aout/aout64.h.

3371 Wed Jun 8 06:28:37 1994 Bill Cox (bill@cygnus.com)
3373 * Makefile.in (check): Delete as.new dependency, so that

3392 * read.c (emit_expr): Use memset to zero out memory, rather than
3393 going through md_number_to_chars. This permits handling symbolic

3446 m68040_control_regs, m68060_control_regs): New arrays.
3447 (control_regs): New pointer.
3448 (m68k_ip): Use control_regs instead of testing CPU every time.
3449 Use last_movec_reg too. In error messages, handle 68060, and
3450 print 68060 for mfloat, too.
3451 (m68k_init_after_args): Handle "68060". Use m68040up for making
3452 m68851 choice. Set control_regs.

3759 (OPTIONAL_REGISTER_PREFIX): Don't define.
3760 (REGISTER_PREFIX_OPTIONAL): If not already defined, define as zero
3761 or one depending on M68KCOFF.
3763 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
3764 * config/tc-m68k.c (DATA, ADDR, SP, FPREG, COPNUM, BAD, BAC):
3765 Define as macros instead of enumerators, since the Apollo compiler
3766 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum
3768 (make_pcrel_absolute) [NO_PCREL_RELOCS]: New function.
3769 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
3770 R_DIR16, and R_DIR32 relocs.
3771 * config/tc-m68k.h [TE_APOLLO] (COFF_MAGIC, COFF_AOUTHDR_MAGIC):
3772 Use Apollo versions.
3773 [TE_APOLLO] (OBJ_COFF_OMIT_OPTIONAL_HEADER): Undefine. That is,
3774 do include the optional header for Apollo target.
3775 (COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
3777 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
3778 can be used within a label name.
3780 * config/tc-m68k.h (m68k_init_after_args): Declare.
3781 (tc_init_after_args): Define as m68k_init_after_args.
3782 * config/tc-m68k.c (m68k_init_after_args): New function,
3783 containing one-shot code from md_assemble. Added warning for
3784 combination of 68040 and 68851.

3799 and bfd_ecoff_set_regmasks to set the GP value and the register
3800 masks, rather than using the now obsolete fake .reginfo section.
3802 Fri Apr 22 15:17:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3804 * listing.c (list_symbol_table): Don't print register symbols as
3807 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
3808 underscores, since symbol_new will already have done it.
3809 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
3811 * as.c (main): If tc_init_after_args is defined, invoke it after
3812 all arguments have been processed.
3814 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
3815 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
3816 section instead of .text. Call create_target_segments.
3817 * read.c (demand_copy_string): No longer static.
3819 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3821 * config/tc-mips.c (append_insn): Permit branches to be switched
3822 with the preceding instruction even if .set nobopt has been seen.
3823 .set nobopt actually controls whether to bring up an instruction
3824 from the branch target, which gas does not currently support.
3826 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3828 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

3841 * config/tc-sparc.c (md_section_align): Always round up to
3842 multiple of alignment power specified in bfd target vector.
3844 * gasp.c: Include ctype.h.

3877 address zero, insert a dummy line to compensate.
3879 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
3882 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3884 * expr.c (operand): Try to parse "0f" and "0b" sequences as
3885 floating point and binary numbers respectively; if it doesn't
3886 work, treat them as local labels.
3888 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
3889 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
3891 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
3893 * vmsconf.sh: In generated file, get ".obj" suffix right, build
3894 source files from other directories into objects in the current
3895 directory, and specify PSECT attributes explicitly to linker.
3896 Also added missing label.
3897 * Makefile.in (stamp-mk.com): Reference new variable
3898 VMS_OTHER_OBJS for list of non-local object files, instead of

3913 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
3914 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
3915 argument, the reloc type.
3916 (load_register): Pass reloc type to macro_build for 'u'.
3917 (macro): Likewise. For M_LA_AB permit a difference expression
3918 when generating embedded PIC code between an arbitrary symbol and
3919 a symbol in the .text section.
3920 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
3921 BFD_RELOC_PCREL_LO16 to be emitted.

3929 * subsegs.c (subsegs_begin): Call memset with args in the correct
3931 (subseg_get): Clear newly allocated seginfo, set its pointer slots
3932 to NULL instead of 0.

3936 * config/tc-hppa.c (pa_procend): Handle case where label was
3937 defined after the .proc directive.
3939 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
3940 procend for a procedure without a name.

3961 (hppa_tc_symbol): Likewise.
3963 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
3964 elf_tc_make_sections stuff. It was there to support PA braindamage
3965 which has been fixed, and in the case of elf_tc_make_sections is
3966 redundant with elf_tc_final_processing.
3968 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3970 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

3975 * config/tc-mips.c (mips_ip): For case 'o', when generating
3976 embedded PIC code, accept the difference between two local symbols
3978 (mips_force_relocation): Only force a reloc to be generated for a
3980 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
3981 value into the file if the fixup will not generate a reloc.
3983 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
3985 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
3986 don't spew remainder of input file in error message.
3987 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
3988 message with reloc type and try to process remainder of file.
3990 * doc/Makefile.in (install-info-as, install-info-gasp): New
3991 targets, now explicitly checking $(srcdir) for info files.
3992 (install-info): Depend on both of them; do nothing more.

3996 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
3998 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4000 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
4001 flag rather than signedp field. Only permit extended range if
4002 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
4003 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
4005 * config/tc-ppc.c (ppc_size): New static variable.
4006 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
4007 (md_begin): If an instruction has a size specific flag set, only
4008 add it if we are assembling that size.
4010 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4012 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
4013 cross section PC relative relocs right for COFF and ELF.
4015 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4017 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
4018 (OBJ_PROCESS_STAB): Don't define.
4020 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4022 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
4023 the type of symbol set symbols which happen to be in the absolute
4024 or undefined section.
4026 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
4028 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
4029 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
4030 and -many (all architectures).
4032 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4034 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
4035 involving a function symbol which is not a plabel to zero.
4036 (md_apply_fix): Never pass a function symbol to field_adjust.
4038 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4040 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
4041 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
4043 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
4044 branch with an instruction that uses $at, in case the branch is
4046 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
4047 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
4048 to make it pcrel_offset.
4049 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
4050 reloc->address; another gruesome hack to get gas reloc handling to
4053 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4055 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
4058 (emit_insn): New function.
4059 (md_assemble): Call it.
4060 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
4062 (lituse_pending): New variable. Set by anything that generates a
4063 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
4064 tested by code that might want to emit a LITUSE reloc.
4065 (emit_unaligned_io): New function. Currently calls md_assemble,
4066 but it should eventually be converted to generate the insn itself
4067 and call emit_insn directly.
4068 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
4069 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
4070 emit_bis_r): Likewise.
4071 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
4072 (alpha_ip, label get_macro): Don't emit the final instruction if
4074 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
4075 unaligned memory access macros.
4076 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
4077 the value can't be resolved.
4079 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4081 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
4082 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
4083 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
4085 (mips_force_relocation): New function.
4086 (md_apply_fix): Set fixP->fx_done appropriately.
4087 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

4095 * config/tc-mips.c (enum mips_pic_level): New enum.
4096 (mips_pic): Change from int to enum mips_pic_level. Change all
4097 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
4098 (load_address): Handle EMBEDDED_PIC.
4099 (macro): Handle EMBEDDED_PIC in all PIC cases.
4100 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
4101 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
4102 -non_shared to use NO_PIC (this is how the Irix 5 assembler
4103 works). Do not permit -G with SVR4_PIC.
4104 (s_abicalls): Warn if -G was used, and force -G 0.
4105 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
4106 anything but a.out, not just for ELF. For ECOFF, don't generate a
4107 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
4109 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
4111 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4113 * config/tc-hppa.c (create_new_space): Use ints, not chars as
4114 parameters to avoid losing when compiling with HP CC.
4115 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
4117 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4119 * Makefile.in (config-stamp): If `defs' is defined, emit a
4120 preprocessor directive to create a macro named by this value into
4121 config.new; don't explicitly go for BFD_ASSEMBLER.
4122 * configure.in: Define `defs', not `BFDDEF'. Set it to
4123 MANY_SEGMENTS for any obj-coffbfd target.
4124 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
4125 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
4127 (LOCAL_LOADLIBES): Deleted.
4128 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
4129 * config/m88kcoff.mt (TDEFINES): Ditto.
4130 * config/ebmon29k.mt: Deleted.
4131 * config/h8300hds.mt: Deleted.
4132 * config/ic960coff.mt: Deleted.
4133 * config/sparc.mt: Deleted.
4134 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
4135 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
4136 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
4137 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.
4138 (TDEFINES): Don't define the coffbfd macros.

4141 (OBJS): Add $(TE_OBJS).
4143 * config/obj-coff.c (obj_pseudo_table): Supply "section"
4146 * write.c (set_symtab): Define only if BFD_ASSEMBLER.
4148 Sun Mar 20 12:06:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4150 * Makefile.in (STAGESTUFF): Add gasp.new.
4152 Fri Mar 18 20:09:16 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4154 * write.c (symbol_table_frozen): New variable, to be set after
4155 bfd_set_symtab is called.
4156 (dump_section_relocs): Note whether a symbol is a section symbol
4158 (adjust_reloc_syms): For now, always supply an absolute symbol for
4159 fixups without symbols but not yet `done'. Use section_symbol to
4160 get the symbol, instead of going directly for abs_symbol.
4161 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
4162 reloc is not a section symbol and is not in the symbol table.
4163 (set_symtab): New function, broken out from write_object_file.
4164 Counts symbol table instead of relying on an earlier count.
4165 (write_object_file): Call set_symtab, but do it after potentially
4166 invoking the *_frob_file macros. Don't bother counting symbols.
4167 Call symbol_remove, instead of expanding it in place. Moved the
4168 conditionalized `object_file_size' declaration down to
4169 conditionalized block where it's used. When using the absolute
4170 symbol for a fixup without a symbol, set sy_used_in_reloc.
4171 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
4172 the correct symbol for the absolute section.
4174 * subsegs.c (section_symbol): Use symbol_new instead of
4175 symbol_make, since we may want it to go into the symbol table.
4176 Make the new symbol have internal linkage. If
4177 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
4178 symbol with the newly created GAS symbol.
4179 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
4180 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
4182 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
4184 * config/tc-sparc.c: Include subsegs.h.
4185 (in_signed_range): New function.
4187 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
4188 (sparc_ip, label "immediate"): Reject constants for pcrel
4189 instructions only if the relocation type indicates a "call"
4190 instruction and the offset is within range of a "jmpl %g0". If
4191 it's not in range, use the absolute section symbol plus an offset.
4192 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
4194 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
4196 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
4199 * configure.in: Eliminated all targets using obj-coff but not
4200 defining BFD_ASSEMBLER; I think all such targets that are

6021 of interest to the linker. ENTRY/EXIT relocations for SOM are
6022 an example of marker relocations.
6023 * write.c (write_relocs): Instead of assuming size of a relocation
6024 is 4 bytes, pick up the size from relocation itself.

6052 BFD_RELOC_MIPS_GPREL. Added new case a.
6053 (set_at, load_register, macro): Changed calls to macro_build to
6054 pass new argument for i, j and o cases.
6055 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
6056 special handling when generating SVR4 PIC code.

6276 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
6277 the table, require that the one without bit 0x1000000 set come

6336 * write.c (write_relocs): For relocs that are pc_relative and
6337 pcrel_offset and not partial_inplace, adjust reloc->addend to

6388 OPTIONAL_REGISTER_PREFIX if either is already defined.
6390 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
6392 * configure.in: Set bfd_gas for all sparc targets. Added facility
6393 for keeping or rejecting configurations still under development;
6394 default is to assume production environment, and reject configs
6395 still being worked on. Mark Elf configurations (except sparc and
6396 i386) as developmental. Deleted cases matching some generic names
6397 in favor of more specific names. (E.g., when we get Alpha

6415 for functions only used within tc-hppa.c, likewise for structures,
6416 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
6417 conditional code in a few small places.

6423 into a few places. Make all functions and variables which
6424 are only used within tc-hppa.c static. PARAMize all functions.
6425 Add comments to functions. Delete unused functions, variables,
6426 #defines, etc. Delete unused members within structures. Delete
6427 ldil;ble hacks -- it is believed they were installed to work
6428 around old gas bugs. Avoid using mixed case for local
6429 functions, variables, and structures. Fix formatting problems
6430 not found by GNU-indent. Add FIXME notices for things which
6431 should be worked on the near future. Delete lots of old
6432 useless (1.36 PA-SOM) code.

6461 a multiple of the section alignment rather than always a
6464 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

6510 of text, data and bss sections to 4.
6511 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
6513 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
6514 ELF, since the ELF object format does not have these type of
6515 relocations. Change the abort into as as_bad and return
6516 BFD_RELOC_NONE to silence compiler warnings.
6517 (md_assemble): Keep track of the instruction size. Allow white
6518 space between the $ and the constant for compatibility with older
6519 gases and other assemblers.

7433 * config/obj-elf.c (obj_elf_stab_generic, in disabled code): If
7434 debug section is new, allocate an extra 12 bytes at its start. If

7594 * Extensive changes to permit symbols to contain any expression
7595 type and to delay the computation of the expression until the
7596 value is actually needed. This permits setting symbols to values
7597 calculated based on object code size. Expressions were changed to
7598 no longer be in a section, to stop the overloading of segment and
7599 expression type that previously occurred.
7601 * as.c (big_section, pass1_section, diff_section, absent_section):
7603 (expr_section): Added (used for dummy symbols which hold

7689 to pop back to it. Handle unquoted section name as well as quoted
7690 section name. Don't crash on invalid strings.
7691 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

8866 references don't appear to work right.
8868 * as.h (const, volatile): Put these definitions back, and use
8871 * doc/as.texinfo: First pass at using new texinfo features --
8872 variables, conditional tests. Far from complete.

8898 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
8899 the bottom (make expands variables in dependencies when the
8900 dependencies are read, not when they are used).
8902 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
8903 a29k .bss section; the mondfe program doesn't like it.

8924 source directory, if that's not the current directory.
8926 * configure.in (per-host): Accept MIPS host with BSD version

8948 process relocs if there aren't any relocs to process. Avoids
8949 malloc/free bug on SCO too.

8952 avoid some redefinition complaints on some systems.
8953 (const, volatile): Don't need these conditionally defined if we
8954 use CONST and VOLATILE from ansidecl.h.
8955 (seg_name): Use CONST, not const.
8957 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
8959 * config/tc-mips.c: Reindented to GNU standards.
8961 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
8963 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
8964 (fixup_segment): Add a29k special case; the linker is not prepared
8965 to see a segment offset here.
8967 * app.c (do_scrub_next_char): Added new state, 10, modifying state
8968 9 to only keep a space in between identifier characters.
8970 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
8972 * Makefile.in: add dvi target; as-$(config).texinfo might live in
8973 srcdir, might be in objdir.

8993 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
8994 bignums, but don't emit error message.
8996 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
8998 * Makefile.in (targ-cpu.o): Depend on config.h.
9000 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
9002 * app.c (do_scrub_next_char): Added new state, 9, to avoid
9003 dropping a space immediately following an identifier.
9004 * expr.c, write.c: Rewrote assert expressions to not use multiple
9005 lines; I don't think that can be done portably.
9006 * config/tc-mips.c (macro): Use $AT if target register is zero in
9007 load instruction, which it can be for a floating point load.
9009 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

9017 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
9020 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
9021 z8k-opc.h, not z8k.h.
9023 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
9026 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9028 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
9030 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
9032 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

9077 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
9078 (struct loc, struct proc, struct file): Moved to tc-mips.c within
9079 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.

9081 prototypes for all static functions. Moved existing minimal
9082 debugging format support info #ifndef OBJ_ECOFF blocks.
9083 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
9084 does not support a non sign extended high 16 bits reloc. Adjusted
9085 all callers accordingly.
9086 (tc_get_register): Renamed from get_register, and made non-static.
9088 * config/mips-big.mt, config/mips-lit.mt: New files. Define

9131 * make-gas.com: Find obstack.obj if it's not in the current
9133 * read.c (s_ignore): Don't declare is_end_of_line. It's
9134 redundant, and triggers a VMS gcc compiler bug.
9136 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
9137 current segment as an argument. (Ignored in all cases but VMS.)
9138 All callers and definitions changed.

9156 argument to s_ignore. Put "#if 0" around unused code.
9157 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
9158 Call elf_xstabs for .stabs and .xstabs operators.
9160 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
9162 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
9165 * configure.in: mips-bsd configuration was missing format spec.
9168 * Makefile.in (Makefile): Depends on configure.in.
9170 * config/tc-mips.c (append_insn): Don't check for alignment of
9171 frag in memory; alignment of instructions in section is a separate
9174 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI

9191 * config/tc-sparc.c (s_xword): Now call big_cons, so large
9192 constants are accepted, but symbolic values are not. GCC will not
9193 generate the latter currently.
9195 * frags.c (frag_init): New function.
9196 (zero_address_frag, bss_address_frag): Now initialized at run
9198 * as.c (main): Call frag_init.

9242 (fixup_segment): Make sure common-section symbols get treated the
9243 same as undefined symbols.
9244 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type
9245 bfd_reloc_code_real_type. Use seg_fix_{root,tail}P derived from

9274 new section/subsection.
9276 * read.c: Don't include ctype.h.
9277 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
9278 for now; should be machine-dependent.
9280 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
9281 targets, forcing BFD use.

9285 * config/tc-sparc.c: Use PARAMS macro for static function
9286 declarations. Use BFD_RELOC_ macros everywhere, with

9303 (write_object_file) [! BFD_ASSEMBLER]: Call it.
9304 (relax_and_size_seg) [BFD_ASSEMBLER]: New function; relax section
9305 and set its size and flags.
9307 * struc-symbol.h (struct symbol) [BFD_ASSEMBLER]: Replace some

9449 md_relax_table): Use default zero initialization.
9450 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
9451 latter, instead of selecting with preprocessor conditionals.
9453 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9455 * configure.in: recognise all sparclite variants
9457 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

9460 accidentally changed to use subseg_change where it should have
9463 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
9465 * expr.c (operand): If character other than comma or newline is a
9466 logical end-of-line character, use the newline case.
9467 From Eric Youngdale:
9468 (operand): Set X_add_number field for floating-point numbers.
9469 (operand): Treat zero byte as end-of-operand.
9471 * configure.in (per-target): Look for with_bfd_assembler option.
9472 For now, only accept "no", until the merge is done.
9474 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
9475 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
9476 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
9477 * read.c: Finish conversion to S_* macros in the VMS only
9478 parts of the program. Add "const" modifier to hex_value.
9479 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
9481 * expr.c: Add "const" modifier to hex_value.
9482 * symbols.c: Finish conversion to S_* macros in the VMS only
9483 parts of the program. Add "const" modifier to
9484 md_[long,short]_jump_size. Remove declaration of const_flag
9485 (which will be declared in obj-vms.h).
9486 * write.c: Add "const" modifier to md_[long,short]_jump_size.
9487 Fix arguments to VMS_write_object_file.
9488 * config-gas.com: New file. Script for VMS systems to set up the
9489 configuration to build gas for VMS, and create config.status.
9490 * make-gas.com: Redone to work with new scheme.
9491 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
9493 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
9494 will swap bytes if needed on a big endian system. Use throughout
9496 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
9497 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
9498 types of malformed stabs. Change parsing algorithm so that we are
9499 more certain of having all of the information that we need on hand.
9500 * obj-vms.c (final_forward_reference): New function, used to help
9501 resolve the data types of as many struct elements as possible
9502 when some part of the struct is not fully defined by the compiler.
9503 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
9505 * obj-vms.c (VMS_write_object_file): Define all vtable psects
9506 as symbols as well in the object file. Look for external functions
9507 that start with "__vt.", and turn them into variables, since the
9508 g++ compiler is incapable of doing this.
9509 * tc-vax.c: Add '1' option for backward compatibility with older GCC
9511 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
9512 * input-scrub.c (as_where): Fix bug where as would crash if we did not
9513 have the name of the source file yet.
9514 * config/ho-vms.h: define HO_VMS, not HO_VAX.
9516 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
9518 * read.c (s_data): Always use "data_section", since it'll map to
9519 SEG_DATA or SEG_E1 if needed.
9520 (s_lcomm): Likewise with bss_section.
9521 (s_fill): Use memset, not bzero.
9523 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

9544 (section_alignment): Declare only if not BFD_ASSEMBLER.
9545 (big_section, reg_section, pass1_section, diff_section,
9546 absent_section, text_section, data_section, bss_section): If
9547 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
9548 mapping to segT enum values.
9549 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
9550 if these are used or defined, if BFD_ASSEMBLER.
9551 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
9552 subseg_new split into two functions.
9553 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
9555 * as.h (volatile): Don't define if already defined.
9556 (had_errors, had_warnings): Provide prototypes for ANSI C even if
9558 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
9559 declare with format attribute for -Wformat checking.
9561 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
9563 * app.c, config/tc-*.c: Don't include read.h, since it is already
9566 * These are based on patches from Minh Tran-le
9567 <mtranle@paris.intellicorp.com>.
9568 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
9569 obj_format coffbfd and gas_target i386coff for target.
9570 (i[34]86-*-isc*): New host (uses sysv).
9571 * config/i386aix.mt: Removed (no longer used).
9572 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
9574 (LDFLAGS): Added, defined as -shlib.
9575 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
9576 * config/te-sco386.h (LOCAL_LABEL): Don't define.
9577 (DOT_LABEL_PREFIX): Define.
9578 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
9579 name rather than L0\001.
9580 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
9582 * symbols.c, symbols.h (local_bss_counter): Removed.
9583 * write.c (write_object_file): bss no longer uses
9584 local_bss_counter. Pass correct data and bss size to
9585 VMS_write_object_file.

9591 (size_section): Restored sanity check.
9592 (do_relocs_for): Base section address on s_paddr rather than
9593 computing it. Adjust a29k R_IHIHALF special case to account for
9594 section paddr (used to require paddr to be zero). If there are no
9595 reclos, set s_relptr to 0. Set relocation size in object_headers.
9596 (fill_section): Always set s_vaddr here, removing
9597 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
9598 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
9599 Set STYP_INFO for .comment.
9600 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
9601 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

9603 H_{SET,GET}_* macros.
9604 (do_linenos_for): Set lineno size in object_headers.
9605 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
9606 set s_vaddr here. If string_byte_count remains 4, set it back to
9607 0, and only write strings out if there are some. Call
9608 fill_section before do_relocs_for and do_linenos_for.
9609 (obj_coff_section): Handle optional quoted second argument giving
9610 section characteristics.
9611 (obj_coff_bss): Added to handle .bss.
9612 (obj_coff_ident): Added to handle .ident (puts string in .comment
9614 (obj_coff_lcomm): Put common symbols in .bss, not .data.
9615 (fixup_mdeps): Change to segment. Call frag_wane after
9617 (fixup_segment): Explicitly check S_IS_COMMON before making 386
9618 adjustment (already happened only for common symbols, but this is

9632 (do_scrub_next_char): For \", return " not '.
9633 (symbol_chars): Now const.
9635 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
9636 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
9638 * config/obj-coff.h: Don't use #elif.
9640 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
9641 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
9643 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
9645 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

9667 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
9668 using ZERO_BASED_SEGMENTS.
9669 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
9670 never set segment address for SEG_E2 (.bss) and don't write out
9671 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
9672 (obj_coff_endef): Don't merge labels or symbols awaiting forward
9673 definitions, and don't merge tags with non-tags. Check for .bf
9674 rather than just checking whether the second character is b and
9675 the third character is f.
9676 (obj_coff_val): gcc can generate values which we don't handle
9677 correctly; discard information for now, since it only affects the
9678 debugging information.
9679 (tag_find_or_name): Don't insert tags in the symbol table.
9680 (yank_symbols): Don't merge labels.
9681 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

9819 * all files: Whitespace changes for GNU indentation style, done by
9820 GNU `indent'. Some cleanup still needed, especially of comments.
9822 * configure.in: No te-386bsd.h file exists; don't try to use it.
9824 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
9826 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
9827 could be doing emulation.
9829 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9832 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
9835 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
9837 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

9844 line_comment_chars, and line_separator_chars.
9846 * tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
9847 still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
9849 (insert_reg): put REGISTER_PREFIX before register names before
9850 putting them in the symbol table.
9851 * tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not
9854 * obj-coffbfd.c (fill_section): set STYP_NOLOAD bit for .bss
9857 * atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
9858 comment_chars, line_comment_chars and line_seperator_chars
9859 consistently const, and always initialized them. Included read.h.
9861 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
9863 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
9864 constant will not fit in an immediate field.
9865 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
9867 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
9869 * obj-coff.c (callj_table): Delete global variable.

9876 * obj-coff.c: Replaced ANSI and non-ANSI function declarations
9877 with a single set using PARAMS macro.
9879 * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length
9882 * tc-i960.c: Missed a couple of 0->NO_RELOC conversions.
9884 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
9885 so widening works consistently.
9887 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
9889 * version.c: Put conditional "const" before version_string, not
9890 before dummy function for VMS. Now version 1.91.03.
9892 * app.c (do_scrub_next_char): Need double-\ before `000' to show
9893 printed rep of null character.
9895 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
9897 * obj-coffbfd.c (write_object_file): check return value of
9900 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
9902 * Support for i386-sysv.
9903 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
9904 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
9905 be used to set them all to zero as was done before.
9906 (fill_section): segment addresses now set in write_object_file.
9907 (fill_section): Don't set STYP_NOLOAD for .bss section.
9908 (fixup_segment): 386 uses strange common symbol format.
9909 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
9910 compatibility with SVR3.2 linker.
9911 * configure.in: i386-sysv and i386-sco use coffbfd.
9913 * app.c (do_scrub_next_char): discard whitespace after a label.
9915 Sat Oct 10 12:33:45 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9917 * configure.in: differentiate between SunOS 4 and Solaris2 for Sun4

9922 fix i960+non-bfd coff bit rot.
9923 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
9924 support for C source listings. (obj_coff_endef): look in the right
9925 part of the symbol for the symbol name
9927 * tc-m68k.c (get_num): make it work for all segments, not just the
9930 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
9932 * configure.in: recognize i386-*-bsd emulation.

9941 * tc-z8k.c: lots of bug fixes
9943 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
9945 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
9946 #elif, since it is not supported by old compilers.
9947 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
9948 couple of expressions in tc-m68k.c.
9950 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9952 * read.c (cons): If NO_RELOC is defined, use it.
9954 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
9956 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
9958 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
9959 local labels to start with a .) and set REGISTER_PREFIX to %.
9960 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
9962 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
9964 * messages.c: Comment changes.
9966 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

9973 * listing.c (debugging_pseudo): Add stabs and stabn as things to
9976 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
9978 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
9979 sections starting from zero, rather than making them consecutive.
9980 This makes subsequent reloc calculations easier, esp if the object
9981 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
9982 allocate lcomm in .data rather than in .bss. It seems that some
9983 tools can't cope with a non-zero sized bss before linkage.
9985 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9987 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
9988 throughout. That enum no longer means what we thought it meant.
9990 * tc-m68k.c (md_assemble, md_parse_option): Handle new
9991 "-mno-688[58]1" options.
9993 * tc-m68k.c: Added CPU32 support.
9995 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9997 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.

10006 * Makefile.in (install): if $(tooldir) exists, install as in
10009 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10011 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10012 .word is < -32768 or > 32767. The -J flag causes the error to be
10013 ignored. This is to catch over-sized switches generated by gcc on
10014 systems which don't support the broken .word hack.
10015 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10016 write.c (fixup_segment): check for signed .word overflow if
10017 WARN_SIGNED_OVERFLOW_WORD.
10019 * write.c (fixup_segment): fixed missing parens in expression
10020 checking for byte or word overflow.
10022 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
10023 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
10024 WARN_SIGNED_OVERFLOW_WORD.
10026 * obj-coffbfd.c (fixup_segment): fixed missing parens in
10027 expression checking for byte or word overflow.

10031 Support for i386 coff
10032 * obj-coffbfd.h : added stuff
10033 * tc-i386.c (tc_coff_fix2rtype): new function
10034 * tc-i386.h : new coff defines
10036 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
10038 * input-scrub.c (input_scrub_push): call input_file_begin, not
10040 messages.c (as_perror): print ": " between the passed in error and
10041 the strerror, like perror does.
10043 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
10045 * Makefile.in: use gas_target instead of modifying target_cpu.
10046 From Steve Chamberlain:
10047 Makefile.in: Handle m68*-*-coff*.

10050 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
10051 Motorola and MIT syntax; gas can now assemble either type of
10053 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
10054 From Steve Chamberlain:
10055 m68kcoff.mt: for m68k COFF.
10056 obj-coffbfd.c: (fixup_mdeps) added
10057 (size_section) removed bad sanity check
10058 (fill_section) added rs_machine_dependent case
10059 (write_object_file) call fixup_mdeps
10060 (fixup_segment) set fx_subsy to 0.
10061 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
10063 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
10066 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10068 * Makefile.in (LIBS): Include opcode library.

10089 * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
10090 tc-i960.c (md_ri_to_chars): Always output bout object file in
10091 little endian byte order (used to use endianness of host).
10093 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10095 * config/tc-m68k.c (init_table): Now const. Always include 68851
10096 data, so that "bc" is available to 68040 cache instructions.
10097 Added "tt0", "tt1", and 68ec030 variants.
10098 (md_assemble): Complain if 68000 (only) and 68881 are specified.
10099 (enum _register): Added TT0, TT1.
10100 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
10101 line number correctly in "internal error" messages. Don't print
10102 architecture-mismatch message for operand errors.
10104 From Colin Smith (colin@wrs.com):
10105 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
10106 than install_operand.

10110 * listing.c (buffer_line): rewind to the start of include
10111 files, they might be included twice.
10113 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
10115 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
10117 * Makefile.in: defined TARGET_CPU for C code so that it can choose
10118 one element of a family.
10120 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
10122 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
10123 so that we can assemble hand-written libgcc code.
10125 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10127 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
10128 has already been formatted (but may still contain %-characters).
10129 (as_bad): Likewise.
10131 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
10133 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
10134 written with indirection on the last two operands, which can be
10135 either data or address registers. Added a new operand type 'r'
10136 which accepts either register type. Added '(' to notend stuff in
10137 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
10139 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
10141 * as.h (enum _relax_state): Start off at one, not zero, to better
10142 catch uninitialized-variable errors.
10143 (linkrelax): Declare new variable.
10145 * messages.c (warning_count, error_count): Default initializer is
10148 * write.c: Merged some declarations, using PARMS macro.

10150 data_last_frag): No longer static.
10151 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
10152 defined, call it. Change segments before calling fixup_segment.
10153 (relax_align): If linkrelax, provide extra padding.
10155 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
10156 their not having symbols associated.
10158 * tc-i960.c (norelax, instrument_branches): Default initializer is
10160 (linkrelax): Delete variable definition.

10181 Mon Aug 17 15:09:56 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10183 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
10184 being used with args swapped, causing occasional lossage when
10185 refilling buffers after an include file.
10187 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
10189 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
10190 version. Discard bogus DONTDEF version.
10191 (as_warn, as_bad, as_fatal): Likewise.

10195 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
10196 selected architecture, print a message saying so and listing what
10197 processors support it, rather than saying "operands mismatch".
10199 Thu Aug 13 13:53:19 1992 Ken Raeburn (raeburn@cygnus.com)
10201 * as.h [BROKEN_ASSERT]: If defined, turn off all assertion checks.

10211 Mon Aug 10 14:37:08 1992 Per Bothner (bothner@cygnus.com)
10213 * tc-m68k.c: ".align N" means align to N-byte boundary *only*
10214 if TN_SUN3; otherwise align to 2**N-byte bounary.
10216 Thu Aug 6 12:10:39 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10218 * read.c (s_fill): make the .fill size clamped error a warn and
10219 fix bug where 0's were always placed.
10221 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
10222 two bytes of any constant with 0xff:
10224 Wed Aug 5 12:02:40 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10226 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
10227 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.
10229 Wed Aug 5 01:54:34 1992 John Gilmore (gnu at cygnus.com)
10231 * tc-m68k.c (try_index): Error if index scaling specified and
10232 assembling for an older CPU than a 68020.
10234 Sat Aug 1 19:10:13 1992 Ken Raeburn (raeburn@cygnus.com)
10236 * config/tc-sparc.c (tc_aout_fix_to_chars): If pc-relative, take
10237 fx_offset into account.

10241 * configure.in (mips host): Accept "ultrix" with version number.
10243 * expr.c (floating_constant): Separate "=-" to avoid confusing
10244 ancient or broken compilers.
10246 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
10247 processor/opcode mismatch, so reword the error message.
10248 (md_assemble): If no CPU has been set (even if FPU/PMMU
10249 characteristics have been), default to 68020. Don't need extra
10250 quotes around error string.
10252 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
10254 * read.c (potable): Revert sac's incorrect change made Jul 13.
10255 Align really is supposed to be ptwo not nbytes.
10257 Mon Jul 20 02:51:59 1992 D. V. Henkel-Wallace (gumby@cygnus.com)
10259 * Makefile.in: _Do_ include libiberty. (from sef)

10386 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
10388 * Makefile.in (install): Install into $(tooldir)/bin, since that's
10389 where gcc looks for it.
10391 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
10393 * Makefile.in: Changed some lines to be less confusing for some

10428 local_labels_fb must be < 10.
10430 * symbols.c: remove local_labels_dollar, replace with a function
10431 interface for a sparse array. All users adjusted.
10433 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
10435 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

10459 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
10461 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
10463 * expr.c (operand): if can't work out what sort of operand it is,
10464 then look through FLT_CHARS for a hint.
10466 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
10468 * Makefile.in, configure.in: removed traces of namesubdir,
10469 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10470 copyrights to '92, changed some from Cygnus to FSF.
10472 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
10473 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10474 copyrights to '92, changed some from Cygnus to FSF.
10476 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10478 * expr.c: If an expression is single comma, then return with
10479 SEG_ABSENT rather than an error - since the sparc front end does
10480 really strange things with things like fbge,a
10482 * as.h: include bfd.h if using many sections
10483 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
10484 local labels didn't work.
10485 * listing.c (list_symbol_table): don't core dump when there's no
10487 * write.c, write.h: call fix_new with the right number of args on
10489 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
10492 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10494 * app.c: MRI compatibility - allow single quote to start a string.
10495 * as.c: fix typo recently introduced.
10496 * as.h : Don't include aout/reloc.h - it's not right for COFF!
10497 * expr.c: Much rewriting, to accomodate MRI syntax for
10498 expressions. Also easier to read now.
10499 * listing.c: Put back defuns
10500 * read.c: modified to accept MRI syntax, put back listing pseudo
10501 ops so that an assembler built with NO_LISTING ignores list ops
10503 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
10504 machine is a SPARC or a 29K.
10505 * config/obj-aout.c: added s_sect pseudo op
10506 * config/obj-coffbfd.c: lints, set the filehdr flags right and
10507 fill in the timestamp.
10508 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
10509 anymore, define all the relocs which the tc-<x> bit will use so we
10510 can translate from them to the coff types.
10511 * config/tc-a29k.c: reloc_type isn't ane enum any more
10512 * config/tc-m68k.c: Added NO_RELOC definition.
10514 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10516 * Makefile.in: put header files before C source for TAGS; remove
10517 references to non-existent syscalls.h.
10519 * read.c, write.c subsegs.c: back out the .bss changes.
10521 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
10523 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
10525 * a.out.h: removed.
10527 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
10529 * symbols.c (local_label_name): symbols now start with ^A.
10531 * read.c, subsegs.c, write.c obj-coff.c: added handling of
10532 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
10533 generate these sections. .align: will use NOP_OPCODE or 0
10534 for padding. This is just for being nice to the
10537 * expr.c (operand): changed to generate local label "\001L0"
10538 starting with a ^A so that it is recognized as a local label.
10540 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
10542 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
10543 i/o opcodes - inb, inw, outb and outw. string manipulation with
10544 att syntax - scmp, slod, smov, ssca, ssto.
10546 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
10547 to just after .file .
10549 In obj_crawl_symbol_chain() where it tries to put the external
10550 symbols apart, with the condition:
10551 (!S_IS_DEFINED(symbolP) &&
10552 !S_IS_DEBUG(symbolP) &&
10553 !SF_GET_STATICS(symbolP))
10554 it was moving too many symbols out. So I switch it back to the
10556 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
10558 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
10559 so that we don't use the F_RELFLG which make the linker complain
10560 that somebody has stripped the relocation info.
10562 Also, the AIX ld program require that the relocation table
10563 is sorted by r_vaddr like the standard ATT assembler does.
10565 [he also changed the sizeof(struct ...)'s into the coff
10566 style FOOSZ macros. I'm not sure this is right, but I can't
10567 remember why. xoxorich.]
10569 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
10571 * Makefile.in, configure.in, doc: use the doc. Build it, install
10574 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
10576 * read.c: white space and comments only.
10578 * configure.in: use the new atof-ns32.c for ns32k.
10580 * write.c: comment change only.
10582 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
10583 aren't yet integrated.
10585 * tc-i860.[hc]: blew off the dust. Something must still be done
10586 about conflicting relocation types.
10588 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
10591 * tc-i960.c, tc-sparc.c: white space and comments only.
10593 * tc-a29k.h: delete duplicate macro definition.
10595 * new file atof-ns32k.c copied from hack's last unreleased gas.
10597 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
10599 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
10602 * nearly everything. flush ChangeLog, package as gas-1.92.1.
10603 ChangeLog's prior to this are sketchy at best. I have logs.
10604 They just aren't ChangeLogs.
