1923 * config/tc-hppa.c (md_apply_fix): Set new_val to 8 for all
1924 fixups to branch instructions (not just pc-relative ones) which

1954 * config/tc-hppa.c: Eliminate all uses of fx_addnumber.
1955 (tc_gen_reloc): Simplify. It's no longer necessary to set a
1956 reloc's addend field to zero for function symbols.
1957 (md_apply_fix): Simplify. For fixups which will require a SOM
1958 reloc, just clear out the necessary bits in the output file.

1962 * Makefile.in (BISON): Use bison -y, not bison.

1976 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
1978 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
1979 it's better to use the one in libiberty.
1981 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1983 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
1984 change; it breaks the rs6000 support, and doesn't seem to be

1998 used to be added by coff_add_linesym, removed Oct 7.
1999 (coff_adjust_section_syms): Ignore sections with no seginfo.
2001 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2003 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a
2004 "stage" symlink to the appropriate stage* directory, and use it
2005 instead in the -B options.
2006 (comparison): Revert yesterday's change.

2013 Tue Oct 11 15:24:00 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
2015 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
2016 for an embedded PIC switch expression, since the definition of
2017 S_IS_LOCAL was changed.
2019 Tue Oct 11 15:05:11 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
2021 * Makefile.in (comparison): When comparing as.new or gasp.new, try
2022 running the binary through sed to avoid differences due to

2035 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
2037 (obj_elf_size): Deleted unused code. If size is non-reducible
2038 expression, allocate some storage for the sy_obj field and copy
2040 (elf_frob_symbol): New function. Computes sizes, calls
2041 ecoff_frob_symbol if appropriate.
2043 * write.c (fixup_segment): For i386 elf and coff (for now), don't

2090 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
2092 (diststuff): New target; builds DISTSTUFF.
2093 (realclean): Separate target, depend on clean and distclean, then
2095 * make-gas.com: Deleted.

2103 Add a space after "pc-relative" in the error message.
2104 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
2105 BFD_RELOC_386_GOTOFF relocs.

2109 (TC_VALIDATE_FIX): New macro -- call it.
2110 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.

2116 referring to PLT entries.
2117 * write.c (fix_new_internal): Initialize fx_plt to zero.
2118 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
2119 Don't adjust fx_offset by frag address, since S_GET_VALUE now
2120 includes the frag address.
2121 (fixup_segment): Changed local var PCREL to type int, added PLT.
2122 If PC-relative fixup refers to a PLT entry for a symbol in the
2123 current section, don't reduce it.

2129 and after processing.
2130 (print_fixup): Added prototype. Show address on first line. Show
2131 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if

2147 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2149 * configure.in: Set bfd_gas for all sparc targets in one place,
2150 instead of separately for each. Correctly handle user-supplied
2151 "--enable-bfd-gas" option.
2153 * gdbinit.in: Move "break abort" to end, in case gdb complains.
2155 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
2158 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
2159 processing if add_symbol is undefined or in expr_section.

2163 (indent_level): No longer static.
2164 (print_symbol_value_1): Don't print frag address if it matches

2168 (print_expr_1): Fix whitespace before printing X_add_number.
2170 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
2171 not symbol_new, for symbols holding expression values.
2172 * expr.h (make_expr_symbol): Move declaration here.
2173 * write.c (fix_new_exp): Handle O_add by creating an
2174 expression-valued symbol, and calling fix_new_exp recursively.
2175 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
2176 undefined symbol and a constant, fold the constant into the fixup,
2177 and refer to the undefined symbol directly. Then process the
2178 fixup again from scratch.
2179 (write_object_file): Before calling adjust_reloc_syms, make a pass
2180 through the symbol list trying to resolve values.
2182 * write.c (print_fixup): New routine, for debugging.
2183 (write_relocs): Call bfd_install_relocation. Deleted various
2184 hacks for working around problems with bfd_perform_relocation.
2186 * Makefile.in (VERSION): Update to 2.4.90.
2188 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2190 * Makefile.in (gasp.o): Depends upon config.h.
2192 * config/tc-mips.c: Include subsegs.h.
2193 (md_apply_fix): If an unconditional b or bal overflows, and we are
2194 not assembling PIC code, replace it with a j or jal.
2196 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
2197 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
2199 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2201 * write.c (write_relocs): Add file name and line number to
2202 as_fatal calls. Handle bfd_reloc_overflow case specifically when
2203 RELOC_EXPANSION_POSSIBLE.
2205 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2207 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
2208 here. Use them for deciding which PRINTF*LIKE macro definitions
2210 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
2211 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
2212 default definitions matching what we were doing before.
2213 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
2214 always use the varargs form if not using stdarg. It's safe to
2215 always use vfprintf, because libiberty will provide it if the
2216 native system doesn't. Also, always make format be const.
2217 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
2219 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

2232 (listing_newline): Check filename as well as line number when
2233 deciding whether to record it.
2234 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
2235 false (if defined) as well as checking for reg_section.
2236 (listing_listing): Iterate fetching lines while line number is too
2237 low, and we haven't run off the end of the input file.
2239 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
2241 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
2243 * ecoff.c (ecoff_generate_asm_lineno): check if
2244 current_stabs_filename is NULL before strcmp.
2245 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
2248 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2250 * config/ho-*.h: Now-unused files deleted.
2252 * symbols.c (copy_symbol_attributes): New function. Copies BFD
2253 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
2254 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
2255 zero. Don't call obj_frob_forward_symbol.
2256 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
2257 X_add_number is zero.
2258 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
2260 * config/tc-i960.c: Lots of whitespace, comment reformatting,
2262 (strchr): Don't declare.
2263 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
2264 md_estimate_size_before_relax, md_ri_to_chars,
2265 md_create_short_jump, md_create_long_jump.
2266 (brtab_emit): Use data_section, not SEG_DATA.
2268 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2270 * config/vms-conf.h: new file, manually derived from conf.in.
2271 * config-gas.com: use it, and eliminate obsolete "host.h".

2275 * config/tc-ppc.c (ppc_current_block): New static variable.
2276 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
2277 ppc_current_block. Don't move around any stab symbol, just those
2279 (ppc_bs): Set ppc_current_block.
2280 (ppc_es): Clear ppc_current_block.
2281 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
2282 from the csect of the enclosing block.
2284 * config/tc-mips.c (insns_since_cache_access): Remove.
2285 (append_insn): Remove setting of insns_since_cache_access, and
2286 special 4600 handling; it turns out not to be required.
2288 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2290 * config/tc-mips.c (md_shortopts): Remove E.
2291 (md_longopts): Add EB and EL.
2292 (md_parse_option): Handle -EB and -EL as separate options, rather
2293 than as a single -E option with an argument.

2297 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
2298 involving global symbols too.
2300 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2302 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
2304 * configure.in: Test for remove, not delete. Fix cross-assembler
2306 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
2309 * read.c (pseudo_set, case O_symbol): If
2310 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
2311 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
2312 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
2314 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
2316 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
2317 many others): new macros; values obtained from "DSTRECRDS.SDL".
2318 * config/obj-vms.h (various): use them.
2319 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
2320 representation (only enum bitfields can avoid being bitstrings).
2321 (bitfield_suffix, setup_basic_type): new routines.
2322 (VMS_typedef_parse): use them. Now recognize bitfields of all
2323 integral types, not just type `int'. Caveat: the representation
2324 used for bitfields still does not work for objects placed in
2325 registers, and gcc's optimizer sometimes puts small structs there.
2327 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2329 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
2330 bit from const_flag.
2331 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
2332 (tc_frob_label): define this to call vms_check_for_special_label,
2333 and declare the latter.
2334 * config/obj-vms.c (vax_g_doubles): declare this file-scope
2336 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
2337 (vms_check_for_special_label): new routine (tc_frob_label).
2338 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
2339 and `gcc2_compiled.' labels; they won't reach here any more.
2340 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
2341 double', use `vax_g_doubles' flag to select type of double.
2342 (VMS_write_object_file) [traceback setup]: don't pass symbols
2343 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
2344 and TBT_Routine_End functions.

2348 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
2349 S_GET_VALUE() to avoid many repeated function calls.
2350 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
2351 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
2352 gets requested. [All the HACK_DEC_C_STARTUP code appears to
2353 be obsolete; gcc does it automatically for vms target. It's
2354 also misnamed, because it is for the "VAX C" run-time library,
2355 not the newer "DEC C" one which has much different startup code.]
2356 {various}: use `S_SET_xxx(symbol,new_value)' rather than
2357 `S_GET_xxx(symbol) = new_value'.
2359 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2361 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
2362 not &bfd_abs_section.
2364 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2366 * expr.c (clean_up_expression): Use addressT, not bfd_vma.

3358 Mon Jun 13 12:08:52 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3360 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
3361 to put a common symbol in a set.

3406 * read.c (emit_expr): Use memset to zero out memory, rather than
3407 going through md_number_to_chars. This permits handling symbolic

3460 m68040_control_regs, m68060_control_regs): New arrays.
3461 (control_regs): New pointer.
3462 (m68k_ip): Use control_regs instead of testing CPU every time.
3463 Use last_movec_reg too. In error messages, handle 68060, and
3464 print 68060 for mfloat, too.
3465 (m68k_init_after_args): Handle "68060". Use m68040up for making
3466 m68851 choice. Set control_regs.

3759 also before setting STYP_NOLOAD for .bss section.
3761 * config/tc-m68k.c (flag_reg_prefix_optional): New variable.
3762 Initialized to value of REGISTER_PREFIX_OPTIONAL, if defined, or

3765 register prefix to be absent.
3766 (m68k_ip_op): Accept `&' also for immediate constants.
3767 (insert_reg): Don't bother with (two!?) sanity checks of the

3771 * config/tc-m68k.h (REGISTER_PREFIX): Always define if not already
3773 (OPTIONAL_REGISTER_PREFIX): Don't define.
3774 (REGISTER_PREFIX_OPTIONAL): If not already defined, define as zero

3778 * config/tc-m68k.c (DATA, ADDR, SP, FPREG, COPNUM, BAD, BAC):
3779 Define as macros instead of enumerators, since the Apollo compiler
3780 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum

3794 * config/tc-m68k.h (m68k_init_after_args): Declare.
3795 (tc_init_after_args): Define as m68k_init_after_args.
3796 * config/tc-m68k.c (m68k_init_after_args): New function,
3797 containing one-shot code from md_assemble. Added warning for

3818 * listing.c (list_symbol_table): Don't print register symbols as
3821 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
3822 underscores, since symbol_new will already have done it.
3823 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
3825 * as.c (main): If tc_init_after_args is defined, invoke it after
3826 all arguments have been processed.

3829 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
3830 section instead of .text. Call create_target_segments.
3831 * read.c (demand_copy_string): No longer static.
3833 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3835 * config/tc-mips.c (append_insn): Permit branches to be switched
3836 with the preceding instruction even if .set nobopt has been seen.
3837 .set nobopt actually controls whether to bring up an instruction
3838 from the branch target, which gas does not currently support.
3840 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3842 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

3893 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
3896 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3898 * expr.c (operand): Try to parse "0f" and "0b" sequences as
3899 floating point and binary numbers respectively; if it doesn't
3900 work, treat them as local labels.
3902 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
3903 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
3905 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
3907 * vmsconf.sh: In generated file, get ".obj" suffix right, build
3908 source files from other directories into objects in the current
3909 directory, and specify PSECT attributes explicitly to linker.
3910 Also added missing label.
3911 * Makefile.in (stamp-mk.com): Reference new variable

3929 argument, the reloc type.
3930 (load_register): Pass reloc type to macro_build for 'u'.
3931 (macro): Likewise. For M_LA_AB permit a difference expression
3932 when generating embedded PIC code between an arbitrary symbol and

3943 * subsegs.c (subsegs_begin): Call memset with args in the correct
3945 (subseg_get): Clear newly allocated seginfo, set its pointer slots

3975 (hppa_tc_symbol): Likewise.
3977 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
3978 elf_tc_make_sections stuff. It was there to support PA braindamage
3979 which has been fixed, and in the case of elf_tc_make_sections is
3980 redundant with elf_tc_final_processing.
3982 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3984 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

3999 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
4000 don't spew remainder of input file in error message.
4001 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
4002 message with reloc type and try to process remainder of file.
4004 * doc/Makefile.in (install-info-as, install-info-gasp): New
4005 targets, now explicitly checking $(srcdir) for info files.
4006 (install-info): Depend on both of them; do nothing more.

4010 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
4012 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4014 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
4015 flag rather than signedp field. Only permit extended range if
4016 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
4017 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
4019 * config/tc-ppc.c (ppc_size): New static variable.
4020 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
4021 (md_begin): If an instruction has a size specific flag set, only
4022 add it if we are assembling that size.
4024 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4026 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
4027 cross section PC relative relocs right for COFF and ELF.
4029 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4031 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
4032 (OBJ_PROCESS_STAB): Don't define.

4036 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
4037 the type of symbol set symbols which happen to be in the absolute
4038 or undefined section.
4040 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
4042 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
4043 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
4044 and -many (all architectures).

4055 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
4057 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
4058 branch with an instruction that uses $at, in case the branch is
4060 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
4061 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
4062 to make it pcrel_offset.
4063 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
4064 reloc->address; another gruesome hack to get gas reloc handling to
4067 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4069 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
4072 (emit_insn): New function.
4073 (md_assemble): Call it.
4074 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
4076 (lituse_pending): New variable. Set by anything that generates a
4077 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
4078 tested by code that might want to emit a LITUSE reloc.
4079 (emit_unaligned_io): New function. Currently calls md_assemble,
4080 but it should eventually be converted to generate the insn itself
4081 and call emit_insn directly.
4082 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
4083 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
4084 emit_bis_r): Likewise.
4085 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
4086 (alpha_ip, label get_macro): Don't emit the final instruction if
4088 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
4089 unaligned memory access macros.
4090 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
4091 the value can't be resolved.
4093 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4095 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
4096 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

4109 * config/tc-mips.c (enum mips_pic_level): New enum.
4110 (mips_pic): Change from int to enum mips_pic_level. Change all
4111 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
4112 (load_address): Handle EMBEDDED_PIC.
4113 (macro): Handle EMBEDDED_PIC in all PIC cases.
4114 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
4115 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
4116 -non_shared to use NO_PIC (this is how the Irix 5 assembler
4117 works). Do not permit -G with SVR4_PIC.
4118 (s_abicalls): Warn if -G was used, and force -G 0.
4119 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
4120 anything but a.out, not just for ELF. For ECOFF, don't generate a
4121 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
4123 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.

4131 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4133 * Makefile.in (config-stamp): If `defs' is defined, emit a
4134 preprocessor directive to create a macro named by this value into
4135 config.new; don't explicitly go for BFD_ASSEMBLER.
4136 * configure.in: Define `defs', not `BFDDEF'. Set it to
4137 MANY_SEGMENTS for any obj-coffbfd target.
4138 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
4139 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
4141 (LOCAL_LOADLIBES): Deleted.
4142 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
4143 * config/m88kcoff.mt (TDEFINES): Ditto.
4144 * config/ebmon29k.mt: Deleted.

4147 * config/sparc.mt: Deleted.
4148 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
4149 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
4150 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
4151 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

4169 bfd_set_symtab is called.
4170 (dump_section_relocs): Note whether a symbol is a section symbol
4172 (adjust_reloc_syms): For now, always supply an absolute symbol for
4173 fixups without symbols but not yet `done'. Use section_symbol to
4174 get the symbol, instead of going directly for abs_symbol.
4175 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
4176 reloc is not a section symbol and is not in the symbol table.
4177 (set_symtab): New function, broken out from write_object_file.
4178 Counts symbol table instead of relying on an earlier count.
4179 (write_object_file): Call set_symtab, but do it after potentially
4180 invoking the *_frob_file macros. Don't bother counting symbols.
4181 Call symbol_remove, instead of expanding it in place. Moved the
4182 conditionalized `object_file_size' declaration down to
4183 conditionalized block where it's used. When using the absolute
4184 symbol for a fixup without a symbol, set sy_used_in_reloc.
4185 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
4186 the correct symbol for the absolute section.
4188 * subsegs.c (section_symbol): Use symbol_new instead of
4189 symbol_make, since we may want it to go into the symbol table.
4190 Make the new symbol have internal linkage. If
4191 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
4192 symbol with the newly created GAS symbol.
4193 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
4194 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

4198 * config/tc-sparc.c: Include subsegs.h.
4199 (in_signed_range): New function.

5999 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
6000 standard hpux include files to pick up various function decls.
6002 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

6035 of interest to the linker. ENTRY/EXIT relocations for SOM are
6036 an example of marker relocations.

6065 assuming BFD_RELOC_LO16. Don't try to convert BFD_RELOC_LO16 to
6066 BFD_RELOC_MIPS_GPREL. Added new case a.
6067 (set_at, load_register, macro): Changed calls to macro_build to
6068 pass new argument for i, j and o cases.

6290 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
6291 the table, require that the one without bit 0x1000000 set come

6350 * write.c (write_relocs): For relocs that are pc_relative and
6351 pcrel_offset and not partial_inplace, adjust reloc->addend to

6402 OPTIONAL_REGISTER_PREFIX if either is already defined.
6404 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
6406 * configure.in: Set bfd_gas for all sparc targets. Added facility
6407 for keeping or rejecting configurations still under development;
6408 default is to assume production environment, and reject configs
6409 still being worked on. Mark Elf configurations (except sparc and
6410 i386) as developmental. Deleted cases matching some generic names
6411 in favor of more specific names. (E.g., when we get Alpha

6428 through inclusion of tc-hppa.h. Delete all forward declarations
6429 for functions only used within tc-hppa.c, likewise for structures,
6430 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
6431 conditional code in a few small places.
6433 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
6434 structures, global variables, forward declarations together.

6436 conditional code -- try to group conditional code together
6437 into a few places. Make all functions and variables which
6438 are only used within tc-hppa.c static. PARAMize all functions.
6439 Add comments to functions. Delete unused functions, variables,
6440 #defines, etc. Delete unused members within structures. Delete
6441 ldil;ble hacks -- it is believed they were installed to work
6442 around old gas bugs. Avoid using mixed case for local
6443 functions, variables, and structures. Fix formatting problems
6444 not found by GNU-indent. Add FIXME notices for things which
6445 should be worked on the near future. Delete lots of old
6446 useless (1.36 PA-SOM) code.

6475 a multiple of the section alignment rather than always a
6478 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
6479 bits are zero (eg they specify no relocations), then do not even
6480 bother adding their entries to thesymextn section.

6521 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
6522 call strchr for each character to see if it is a special char,

6524 of text, data and bss sections to 4.
6525 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
6527 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
6528 ELF, since the ELF object format does not have these type of
6529 relocations. Change the abort into as as_bad and return
6530 BFD_RELOC_NONE to silence compiler warnings.
6531 (md_assemble): Keep track of the instruction size. Allow white
6532 space between the $ and the constant for compatibility with older
6533 gases and other assemblers.

7608 * Extensive changes to permit symbols to contain any expression
7609 type and to delay the computation of the expression until the
7610 value is actually needed. This permits setting symbols to values
7611 calculated based on object code size. Expressions were changed to
7612 no longer be in a section, to stop the overloading of segment and
7613 expression type that previously occurred.
7615 * as.c (big_section, pass1_section, diff_section, absent_section):
7617 (expr_section): Added (used for dummy symbols which hold

7701 (previous_section, previous_subsection): New vars.
7702 (obj_elf_section): Save current place in case DWARF code wants us
7703 to pop back to it. Handle unquoted section name as well as quoted
7704 section name. Don't crash on invalid strings.
7705 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

7817 sy_resolved and sy_resolving single bit fields.
7818 * symbols.c (symbol_new): Don't initialize sy_forward field.

8852 than ECOFF line number information.
8853 (obj_ecoff_stab): Accept non-zero values for stabs line number.

8880 references don't appear to work right.
8882 * as.h (const, volatile): Put these definitions back, and use
8885 * doc/as.texinfo: First pass at using new texinfo features --
8886 variables, conditional tests. Far from complete.

8912 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
8913 the bottom (make expands variables in dependencies when the
8914 dependencies are read, not when they are used).
8916 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
8917 a29k .bss section; the mondfe program doesn't like it.

8938 source directory, if that's not the current directory.
8940 * configure.in (per-host): Accept MIPS host with BSD version

8962 process relocs if there aren't any relocs to process. Avoids
8963 malloc/free bug on SCO too.
8965 * as.h: Move local include files below system include files, to
8966 avoid some redefinition complaints on some systems.
8967 (const, volatile): Don't need these conditionally defined if we
8968 use CONST and VOLATILE from ansidecl.h.
8969 (seg_name): Use CONST, not const.
8971 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
8973 * config/tc-mips.c: Reindented to GNU standards.
8975 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
8977 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
8978 (fixup_segment): Add a29k special case; the linker is not prepared
8979 to see a segment offset here.
8981 * app.c (do_scrub_next_char): Added new state, 10, modifying state
8982 9 to only keep a space in between identifier characters.
8984 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
8986 * Makefile.in: add dvi target; as-$(config).texinfo might live in
8987 srcdir, might be in objdir.
8989 * doc/Makefile.in: dvi depends on as.dvi

9007 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
9008 bignums, but don't emit error message.
9010 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
9012 * Makefile.in (targ-cpu.o): Depend on config.h.
9014 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
9016 * app.c (do_scrub_next_char): Added new state, 9, to avoid
9017 dropping a space immediately following an identifier.
9018 * expr.c, write.c: Rewrote assert expressions to not use multiple
9019 lines; I don't think that can be done portably.
9020 * config/tc-mips.c (macro): Use $AT if target register is zero in
9021 load instruction, which it can be for a floating point load.
9023 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

9031 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
9034 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
9035 z8k-opc.h, not z8k.h.
9037 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
9040 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9042 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
9044 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
9046 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

9091 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
9092 (struct loc, struct proc, struct file): Moved to tc-mips.c within
9093 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
9094 * config/tc-mips.c: Rearranged for ECOFF support. Added
9095 prototypes for all static functions. Moved existing minimal
9096 debugging format support info #ifndef OBJ_ECOFF blocks.
9097 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
9098 does not support a non sign extended high 16 bits reloc. Adjusted
9099 all callers accordingly.
9100 (tc_get_register): Renamed from get_register, and made non-static.
9102 * config/mips-big.mt, config/mips-lit.mt: New files. Define

9145 * make-gas.com: Find obstack.obj if it's not in the current
9147 * read.c (s_ignore): Don't declare is_end_of_line. It's
9148 redundant, and triggers a VMS gcc compiler bug.
9150 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
9151 current segment as an argument. (Ignored in all cases but VMS.)
9152 All callers and definitions changed.

9170 argument to s_ignore. Put "#if 0" around unused code.
9171 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
9172 Call elf_xstabs for .stabs and .xstabs operators.
9174 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
9176 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
9179 * configure.in: mips-bsd configuration was missing format spec.
9182 * Makefile.in (Makefile): Depends on configure.in.
9184 * config/tc-mips.c (append_insn): Don't check for alignment of
9185 frag in memory; alignment of instructions in section is a separate
9188 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI

9205 * config/tc-sparc.c (s_xword): Now call big_cons, so large
9206 constants are accepted, but symbolic values are not. GCC will not
9207 generate the latter currently.
9209 * frags.c (frag_init): New function.
9210 (zero_address_frag, bss_address_frag): Now initialized at run
9212 * as.c (main): Call frag_init.

9256 (fixup_segment): Make sure common-section symbols get treated the
9257 same as undefined symbols.
9258 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type
9259 bfd_reloc_code_real_type. Use seg_fix_{root,tail}P derived from

9266 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and
9269 * symbols.c (symbol_new): Argument NAME is now pointer to const.
9270 Simplified STRIP_UNDERSCORE code. Remove assumptions about null
9271 pointers in freshly allocated storage. [BFD_ASSEMBLER]: Get new

9288 new section/subsection.
9290 * read.c: Don't include ctype.h.
9291 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
9292 for now; should be machine-dependent.
9294 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
9295 targets, forcing BFD use.

9299 * config/tc-sparc.c: Use PARAMS macro for static function
9300 declarations. Use BFD_RELOC_ macros everywhere, with
9301 compatibility macros declared for non-BFD mode.

9313 of referencing fields directly.
9315 * write.c (cvt_frag_to_fill): New function; extracted from
9317 (write_object_file) [! BFD_ASSEMBLER]: Call it.
9318 (relax_and_size_seg) [BFD_ASSEMBLER]: New function; relax section
9319 and set its size and flags.
9321 * struc-symbol.h (struct symbol) [BFD_ASSEMBLER]: Replace some

9464 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
9465 latter, instead of selecting with preprocessor conditionals.
9467 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9469 * configure.in: recognise all sparclite variants

9479 * expr.c (operand): If character other than comma or newline is a
9480 logical end-of-line character, use the newline case.
9481 From Eric Youngdale:
9482 (operand): Set X_add_number field for floating-point numbers.
9483 (operand): Treat zero byte as end-of-operand.
9485 * configure.in (per-target): Look for with_bfd_assembler option.
9486 For now, only accept "no", until the merge is done.
9488 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
9489 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
9490 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
9491 * read.c: Finish conversion to S_* macros in the VMS only
9492 parts of the program. Add "const" modifier to hex_value.

9495 * expr.c: Add "const" modifier to hex_value.
9496 * symbols.c: Finish conversion to S_* macros in the VMS only
9497 parts of the program. Add "const" modifier to
9498 md_[long,short]_jump_size. Remove declaration of const_flag
9499 (which will be declared in obj-vms.h).
9500 * write.c: Add "const" modifier to md_[long,short]_jump_size.
9501 Fix arguments to VMS_write_object_file.
9502 * config-gas.com: New file. Script for VMS systems to set up the
9503 configuration to build gas for VMS, and create config.status.
9504 * make-gas.com: Redone to work with new scheme.
9505 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
9507 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
9508 will swap bytes if needed on a big endian system. Use throughout
9510 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
9511 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
9512 types of malformed stabs. Change parsing algorithm so that we are
9513 more certain of having all of the information that we need on hand.
9514 * obj-vms.c (final_forward_reference): New function, used to help
9515 resolve the data types of as many struct elements as possible
9516 when some part of the struct is not fully defined by the compiler.

9519 * obj-vms.c (VMS_write_object_file): Define all vtable psects
9520 as symbols as well in the object file. Look for external functions

9522 g++ compiler is incapable of doing this.
9523 * tc-vax.c: Add '1' option for backward compatibility with older GCC
9525 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
9526 * input-scrub.c (as_where): Fix bug where as would crash if we did not
9527 have the name of the source file yet.
9528 * config/ho-vms.h: define HO_VMS, not HO_VAX.
9530 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
9532 * read.c (s_data): Always use "data_section", since it'll map to
9533 SEG_DATA or SEG_E1 if needed.
9534 (s_lcomm): Likewise with bss_section.
9535 (s_fill): Use memset, not bzero.
9537 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

9558 (section_alignment): Declare only if not BFD_ASSEMBLER.
9559 (big_section, reg_section, pass1_section, diff_section,
9560 absent_section, text_section, data_section, bss_section): If
9561 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
9562 mapping to segT enum values.
9563 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
9564 if these are used or defined, if BFD_ASSEMBLER.
9565 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
9566 subseg_new split into two functions.
9567 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
9569 * as.h (volatile): Don't define if already defined.
9570 (had_errors, had_warnings): Provide prototypes for ANSI C even if
9572 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
9573 declare with format attribute for -Wformat checking.
9575 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
9577 * app.c, config/tc-*.c: Don't include read.h, since it is already
9580 * These are based on patches from Minh Tran-le
9581 <mtranle@paris.intellicorp.com>.
9582 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
9583 obj_format coffbfd and gas_target i386coff for target.
9584 (i[34]86-*-isc*): New host (uses sysv).
9585 * config/i386aix.mt: Removed (no longer used).
9586 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
9588 (LDFLAGS): Added, defined as -shlib.
9589 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
9590 * config/te-sco386.h (LOCAL_LABEL): Don't define.
9591 (DOT_LABEL_PREFIX): Define.
9592 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
9593 name rather than L0\001.
9594 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
9596 * symbols.c, symbols.h (local_bss_counter): Removed.
9597 * write.c (write_object_file): bss no longer uses

9605 (size_section): Restored sanity check.
9606 (do_relocs_for): Base section address on s_paddr rather than
9607 computing it. Adjust a29k R_IHIHALF special case to account for
9608 section paddr (used to require paddr to be zero). If there are no
9609 reclos, set s_relptr to 0. Set relocation size in object_headers.
9610 (fill_section): Always set s_vaddr here, removing
9611 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
9612 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
9613 Set STYP_INFO for .comment.
9614 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
9615 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

9617 H_{SET,GET}_* macros.
9618 (do_linenos_for): Set lineno size in object_headers.
9619 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
9620 set s_vaddr here. If string_byte_count remains 4, set it back to
9621 0, and only write strings out if there are some. Call
9622 fill_section before do_relocs_for and do_linenos_for.
9623 (obj_coff_section): Handle optional quoted second argument giving
9624 section characteristics.
9625 (obj_coff_bss): Added to handle .bss.
9626 (obj_coff_ident): Added to handle .ident (puts string in .comment
9628 (obj_coff_lcomm): Put common symbols in .bss, not .data.
9629 (fixup_mdeps): Change to segment. Call frag_wane after
9631 (fixup_segment): Explicitly check S_IS_COMMON before making 386
9632 adjustment (already happened only for common symbols, but this is

9646 (do_scrub_next_char): For \", return " not '.
9647 (symbol_chars): Now const.
9649 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
9650 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
9652 * config/obj-coff.h: Don't use #elif.
9654 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
9655 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
9657 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
9659 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

9679 SEG_BSS, fill with NOP_OPCODE.
9680 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
9681 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
9682 using ZERO_BASED_SEGMENTS.
9683 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
9684 never set segment address for SEG_E2 (.bss) and don't write out
9685 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
9686 (obj_coff_endef): Don't merge labels or symbols awaiting forward
9687 definitions, and don't merge tags with non-tags. Check for .bf
9688 rather than just checking whether the second character is b and
9689 the third character is f.
9690 (obj_coff_val): gcc can generate values which we don't handle
9691 correctly; discard information for now, since it only affects the
9692 debugging information.

9694 (yank_symbols): Don't merge labels.
9695 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

9750 options. Updated options documentation for m68k. Some minor
9751 wording/punctuation changes.

9838 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
9840 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
9841 could be doing emulation.
9843 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9846 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
9849 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)

9860 * tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
9861 still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
9863 (insert_reg): put REGISTER_PREFIX before register names before
9864 putting them in the symbol table.
9865 * tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not

9873 consistently const, and always initialized them. Included read.h.
9875 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
9877 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
9878 constant will not fit in an immediate field.
9879 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
9881 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

9890 * obj-coff.c: Replaced ANSI and non-ANSI function declarations
9891 with a single set using PARAMS macro.
9893 * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length

9898 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
9899 so widening works consistently.
9901 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
9903 * version.c: Put conditional "const" before version_string, not
9904 before dummy function for VMS. Now version 1.91.03.
9906 * app.c (do_scrub_next_char): Need double-\ before `000' to show
9907 printed rep of null character.
9909 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
9911 * obj-coffbfd.c (write_object_file): check return value of
9914 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
9916 * Support for i386-sysv.
9917 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
9918 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
9919 be used to set them all to zero as was done before.
9920 (fill_section): segment addresses now set in write_object_file.
9921 (fill_section): Don't set STYP_NOLOAD for .bss section.
9922 (fixup_segment): 386 uses strange common symbol format.
9923 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
9924 compatibility with SVR3.2 linker.
9925 * configure.in: i386-sysv and i386-sco use coffbfd.
9927 * app.c (do_scrub_next_char): discard whitespace after a label.
9929 Sat Oct 10 12:33:45 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9931 * configure.in: differentiate between SunOS 4 and Solaris2 for Sun4
9932 hosts, use the sysv configuration for solaris2

9936 fix i960+non-bfd coff bit rot.
9937 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
9938 support for C source listings. (obj_coff_endef): look in the right

9952 Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9954 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
9955 * tc-z8k.c: lots of bug fixes
9957 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
9959 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
9960 #elif, since it is not supported by old compilers.
9961 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
9962 couple of expressions in tc-m68k.c.
9964 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9966 * read.c (cons): If NO_RELOC is defined, use it.
9968 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
9970 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
9972 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
9973 local labels to start with a .) and set REGISTER_PREFIX to %.
9974 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
9976 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
9978 * messages.c: Comment changes.
9980 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

9987 * listing.c (debugging_pseudo): Add stabs and stabn as things to
9990 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
9992 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
9993 sections starting from zero, rather than making them consecutive.
9994 This makes subsequent reloc calculations easier, esp if the object
9995 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
9996 allocate lcomm in .data rather than in .bss. It seems that some
9997 tools can't cope with a non-zero sized bss before linkage.
9999 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10001 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10002 throughout. That enum no longer means what we thought it meant.
10004 * tc-m68k.c (md_assemble, md_parse_option): Handle new
10005 "-mno-688[58]1" options.
10007 * tc-m68k.c: Added CPU32 support.
10009 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

10020 * Makefile.in (install): if $(tooldir) exists, install as in
10023 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10025 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10026 .word is < -32768 or > 32767. The -J flag causes the error to be
10027 ignored. This is to catch over-sized switches generated by gcc on
10028 systems which don't support the broken .word hack.
10029 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10030 write.c (fixup_segment): check for signed .word overflow if
10031 WARN_SIGNED_OVERFLOW_WORD.
10033 * write.c (fixup_segment): fixed missing parens in expression
10034 checking for byte or word overflow.
10036 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
10037 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
10038 WARN_SIGNED_OVERFLOW_WORD.
10040 * obj-coffbfd.c (fixup_segment): fixed missing parens in
10041 expression checking for byte or word overflow.
10043 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10045 Support for i386 coff
10046 * obj-coffbfd.h : added stuff
10047 * tc-i386.c (tc_coff_fix2rtype): new function
10048 * tc-i386.h : new coff defines
10050 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
10052 * input-scrub.c (input_scrub_push): call input_file_begin, not
10054 messages.c (as_perror): print ": " between the passed in error and
10055 the strerror, like perror does.
10057 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
10059 * Makefile.in: use gas_target instead of modifying target_cpu.
10060 From Steve Chamberlain:
10061 Makefile.in: Handle m68*-*-coff*.

10064 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
10065 Motorola and MIT syntax; gas can now assemble either type of
10067 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
10068 From Steve Chamberlain:
10069 m68kcoff.mt: for m68k COFF.
10070 obj-coffbfd.c: (fixup_mdeps) added
10071 (size_section) removed bad sanity check
10072 (fill_section) added rs_machine_dependent case
10073 (write_object_file) call fixup_mdeps
10074 (fixup_segment) set fx_subsy to 0.
10075 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
10077 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
10080 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10082 * Makefile.in (LIBS): Include opcode library.
10084 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
10086 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
10087 including zero are accepted, pass +0.0.

10103 * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
10104 tc-i960.c (md_ri_to_chars): Always output bout object file in
10105 little endian byte order (used to use endianness of host).
10107 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10109 * config/tc-m68k.c (init_table): Now const. Always include 68851
10110 data, so that "bc" is available to 68040 cache instructions.
10111 Added "tt0", "tt1", and 68ec030 variants.
10112 (md_assemble): Complain if 68000 (only) and 68881 are specified.
10113 (enum _register): Added TT0, TT1.
10114 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
10115 line number correctly in "internal error" messages. Don't print
10116 architecture-mismatch message for operand errors.
10118 From Colin Smith (colin@wrs.com):
10119 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
10120 than install_operand.
10122 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10124 * listing.c (buffer_line): rewind to the start of include
10125 files, they might be included twice.
10127 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
10129 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
10131 * Makefile.in: defined TARGET_CPU for C code so that it can choose
10132 one element of a family.
10134 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
10136 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
10137 so that we can assemble hand-written libgcc code.
10139 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10141 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
10142 has already been formatted (but may still contain %-characters).
10143 (as_bad): Likewise.
10145 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
10147 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
10148 written with indirection on the last two operands, which can be
10149 either data or address registers. Added a new operand type 'r'
10150 which accepts either register type. Added '(' to notend stuff in
10151 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
10153 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
10155 * as.h (enum _relax_state): Start off at one, not zero, to better
10156 catch uninitialized-variable errors.
10157 (linkrelax): Declare new variable.
10159 * messages.c (warning_count, error_count): Default initializer is
10162 * write.c: Merged some declarations, using PARMS macro.

10164 data_last_frag): No longer static.
10165 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
10166 defined, call it. Change segments before calling fixup_segment.
10167 (relax_align): If linkrelax, provide extra padding.
10169 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
10170 their not having symbols associated.
10172 * tc-i960.c (norelax, instrument_branches): Default initializer is
10174 (linkrelax): Delete variable definition.

10190 MINUS_G, set CFLAGS to default to -g, added FLAGS_TO_PASS, passed
10191 FLAGS_TO_PASS to recursive makes.
10193 * doc/Makefile.in: always create installation directories.
10195 Mon Aug 17 15:09:56 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10197 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
10198 being used with args swapped, causing occasional lossage when
10199 refilling buffers after an include file.
10201 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
10203 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
10204 version. Discard bogus DONTDEF version.
10205 (as_warn, as_bad, as_fatal): Likewise.
10207 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
10209 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
10210 selected architecture, print a message saying so and listing what
10211 processors support it, rather than saying "operands mismatch".
10213 Thu Aug 13 13:53:19 1992 Ken Raeburn (raeburn@cygnus.com)
10215 * as.h [BROKEN_ASSERT]: If defined, turn off all assertion checks.

10223 * sparc.mt: New file.
10225 Mon Aug 10 14:37:08 1992 Per Bothner (bothner@cygnus.com)
10227 * tc-m68k.c: ".align N" means align to N-byte boundary *only*
10228 if TN_SUN3; otherwise align to 2**N-byte bounary.
10230 Thu Aug 6 12:10:39 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10232 * read.c (s_fill): make the .fill size clamped error a warn and
10233 fix bug where 0's were always placed.
10235 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
10236 two bytes of any constant with 0xff:
10238 Wed Aug 5 12:02:40 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10240 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
10241 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.
10243 Wed Aug 5 01:54:34 1992 John Gilmore (gnu at cygnus.com)
10245 * tc-m68k.c (try_index): Error if index scaling specified and
10246 assembling for an older CPU than a 68020.
10248 Sat Aug 1 19:10:13 1992 Ken Raeburn (raeburn@cygnus.com)
10250 * config/tc-sparc.c (tc_aout_fix_to_chars): If pc-relative, take
10251 fx_offset into account.
10253 Fri Jul 31 21:53:28 1992 Ken Raeburn (raeburn@cygnus.com)
10255 * configure.in (mips host): Accept "ultrix" with version number.
10257 * expr.c (floating_constant): Separate "=-" to avoid confusing
10258 ancient or broken compilers.
10260 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
10261 processor/opcode mismatch, so reword the error message.
10262 (md_assemble): If no CPU has been set (even if FPU/PMMU
10263 characteristics have been), default to 68020. Don't need extra
10264 quotes around error string.
10266 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
10268 * read.c (potable): Revert sac's incorrect change made Jul 13.
10269 Align really is supposed to be ptwo not nbytes.
10271 Mon Jul 20 02:51:59 1992 D. V. Henkel-Wallace (gumby@cygnus.com)
10273 * Makefile.in: _Do_ include libiberty. (from sef)

10400 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
10402 * Makefile.in (install): Install into $(tooldir)/bin, since that's
10403 where gcc looks for it.
10405 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
10407 * Makefile.in: Changed some lines to be less confusing for some

10473 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
10475 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
10477 * expr.c (operand): if can't work out what sort of operand it is,
10478 then look through FLT_CHARS for a hint.
10480 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
10482 * Makefile.in, configure.in: removed traces of namesubdir,
10483 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10484 copyrights to '92, changed some from Cygnus to FSF.
10486 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
10487 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10488 copyrights to '92, changed some from Cygnus to FSF.
10490 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10492 * expr.c: If an expression is single comma, then return with
10493 SEG_ABSENT rather than an error - since the sparc front end does
10494 really strange things with things like fbge,a
10496 * as.h: include bfd.h if using many sections
10497 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
10498 local labels didn't work.
10499 * listing.c (list_symbol_table): don't core dump when there's no
10501 * write.c, write.h: call fix_new with the right number of args on
10503 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
10506 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10508 * app.c: MRI compatibility - allow single quote to start a string.
10509 * as.c: fix typo recently introduced.
10510 * as.h : Don't include aout/reloc.h - it's not right for COFF!
10511 * expr.c: Much rewriting, to accomodate MRI syntax for
10512 expressions. Also easier to read now.
10513 * listing.c: Put back defuns
10514 * read.c: modified to accept MRI syntax, put back listing pseudo
10515 ops so that an assembler built with NO_LISTING ignores list ops
10517 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
10518 machine is a SPARC or a 29K.
10519 * config/obj-aout.c: added s_sect pseudo op
10520 * config/obj-coffbfd.c: lints, set the filehdr flags right and
10521 fill in the timestamp.
10522 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
10523 anymore, define all the relocs which the tc-<x> bit will use so we
10524 can translate from them to the coff types.
10525 * config/tc-a29k.c: reloc_type isn't ane enum any more
10526 * config/tc-m68k.c: Added NO_RELOC definition.
10528 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10530 * Makefile.in: put header files before C source for TAGS; remove
10531 references to non-existent syscalls.h.
10533 * read.c, write.c subsegs.c: back out the .bss changes.
10535 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
10537 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
10539 * a.out.h: removed.
10541 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
10543 * symbols.c (local_label_name): symbols now start with ^A.
10545 * read.c, subsegs.c, write.c obj-coff.c: added handling of
10546 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
10547 generate these sections. .align: will use NOP_OPCODE or 0
10548 for padding. This is just for being nice to the
10551 * expr.c (operand): changed to generate local label "\001L0"
10552 starting with a ^A so that it is recognized as a local label.
10554 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
10556 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
10557 i/o opcodes - inb, inw, outb and outw. string manipulation with
10558 att syntax - scmp, slod, smov, ssca, ssto.
10560 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
10561 to just after .file .
10563 In obj_crawl_symbol_chain() where it tries to put the external
10564 symbols apart, with the condition:
10565 (!S_IS_DEFINED(symbolP) &&
10566 !S_IS_DEBUG(symbolP) &&
10567 !SF_GET_STATICS(symbolP))
10568 it was moving too many symbols out. So I switch it back to the
10570 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
10572 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
10573 so that we don't use the F_RELFLG which make the linker complain
10574 that somebody has stripped the relocation info.
10576 Also, the AIX ld program require that the relocation table
10577 is sorted by r_vaddr like the standard ATT assembler does.
10579 [he also changed the sizeof(struct ...)'s into the coff
10580 style FOOSZ macros. I'm not sure this is right, but I can't
10581 remember why. xoxorich.]
10583 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
10585 * Makefile.in, configure.in, doc: use the doc. Build it, install
10588 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
10590 * read.c: white space and comments only.
10592 * configure.in: use the new atof-ns32.c for ns32k.
10594 * write.c: comment change only.
10596 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
10597 aren't yet integrated.
10599 * tc-i860.[hc]: blew off the dust. Something must still be done
10600 about conflicting relocation types.
10602 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
10605 * tc-i960.c, tc-sparc.c: white space and comments only.
10607 * tc-a29k.h: delete duplicate macro definition.
10609 * new file atof-ns32k.c copied from hack's last unreleased gas.
10611 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
10613 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
10616 * nearly everything. flush ChangeLog, package as gas-1.92.1.
10617 ChangeLog's prior to this are sketchy at best. I have logs.
10618 They just aren't ChangeLogs.
