1924 * config/tc-mips.c (md_pseudo_table): If OBJ_ELF, handle .section.
1925 (s_elf_section): New static function.
1926 * ecoff.c (ecoff_build_symbols): Don't abort if we don't recognize

1931 * config/tc-hppa.c (md_apply_fix): Set new_val to 8 for all
1932 fixups to branch instructions (not just pc-relative ones) which

1962 * config/tc-hppa.c: Eliminate all uses of fx_addnumber.
1963 (tc_gen_reloc): Simplify. It's no longer necessary to set a
1964 reloc's addend field to zero for function symbols.
1965 (md_apply_fix): Simplify. For fixups which will require a SOM
1966 reloc, just clear out the necessary bits in the output file.

1970 * Makefile.in (BISON): Use bison -y, not bison.

1984 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
1986 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
1987 it's better to use the one in libiberty.
1989 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1991 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
1992 change; it breaks the rs6000 support, and doesn't seem to be
1995 Wed Oct 12 11:56:50 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
1997 * config/tc-i386.h,te-netbsd532.h (TARGET_FORMAT): Changed to

2003 rather than explicitly adding the frag address.
2004 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark

2006 used to be added by coff_add_linesym, removed Oct 7.
2007 (coff_adjust_section_syms): Ignore sections with no seginfo.
2009 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2011 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a
2012 "stage" symlink to the appropriate stage* directory, and use it
2013 instead in the -B options.
2014 (comparison): Revert yesterday's change.
2016 Tue Oct 11 16:48:11 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

2021 Tue Oct 11 15:24:00 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
2023 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
2024 for an embedded PIC switch expression, since the definition of
2025 S_IS_LOCAL was changed.
2027 Tue Oct 11 15:05:11 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
2029 * Makefile.in (comparison): When comparing as.new or gasp.new, try
2030 running the binary through sed to avoid differences due to
2031 "stage1" or "stage2" having been written into the binary.
2033 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
2035 ELF symbol size handling, based on code from Eric Youngdale:
2036 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an

2043 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
2045 (obj_elf_size): Deleted unused code. If size is non-reducible
2046 expression, allocate some storage for the sy_obj field and copy
2048 (elf_frob_symbol): New function. Computes sizes, calls
2049 ecoff_frob_symbol if appropriate.
2051 * write.c (fixup_segment): For i386 elf and coff (for now), don't
2052 add in value of symbol from another defined section of the file.

2098 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
2100 (diststuff): New target; builds DISTSTUFF.
2101 (realclean): Separate target, depend on clean and distclean, then
2103 * make-gas.com: Deleted.

2106 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
2108 (i386_operand): Don't look up section symbol for
2110 (reloc): Always permit return of 8- and 16-bit relocation types.
2111 Add a space after "pc-relative" in the error message.
2112 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
2113 BFD_RELOC_386_GOTOFF relocs.

2117 (TC_VALIDATE_FIX): New macro -- call it.
2118 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.

2124 referring to PLT entries.
2125 * write.c (fix_new_internal): Initialize fx_plt to zero.
2126 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
2127 Don't adjust fx_offset by frag address, since S_GET_VALUE now
2128 includes the frag address.
2129 (fixup_segment): Changed local var PCREL to type int, added PLT.
2130 If PC-relative fixup refers to a PLT entry for a symbol in the
2131 current section, don't reduce it.

2137 and after processing.
2138 (print_fixup): Added prototype. Show address on first line. Show
2139 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if

2153 Show fx_r_type and fx_addsy fields.
2155 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2157 * configure.in: Set bfd_gas for all sparc targets in one place,
2158 instead of separately for each. Correctly handle user-supplied
2159 "--enable-bfd-gas" option.
2161 * gdbinit.in: Move "break abort" to end, in case gdb complains.
2163 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
2166 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
2167 processing if add_symbol is undefined or in expr_section.
2168 (resolve_symbol_value, case O_add): For symbol plus
2169 constant-valued symbol, convert to O_symbol and re-reduce.
2170 (S_GET_VALUE): If symbol needs resolving, resolve it.
2171 (indent_level): No longer static.
2172 (print_symbol_value_1): Don't print frag address if it matches
2173 zero_address_frag. Don't print "resolving" if already resolved.

2176 (print_expr_1): Fix whitespace before printing X_add_number.
2178 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
2179 not symbol_new, for symbols holding expression values.
2180 * expr.h (make_expr_symbol): Move declaration here.
2181 * write.c (fix_new_exp): Handle O_add by creating an
2182 expression-valued symbol, and calling fix_new_exp recursively.
2183 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
2184 undefined symbol and a constant, fold the constant into the fixup,
2185 and refer to the undefined symbol directly. Then process the
2186 fixup again from scratch.
2187 (write_object_file): Before calling adjust_reloc_syms, make a pass
2188 through the symbol list trying to resolve values.
2190 * write.c (print_fixup): New routine, for debugging.
2191 (write_relocs): Call bfd_install_relocation. Deleted various
2192 hacks for working around problems with bfd_perform_relocation.
2194 * Makefile.in (VERSION): Update to 2.4.90.
2196 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2198 * Makefile.in (gasp.o): Depends upon config.h.
2200 * config/tc-mips.c: Include subsegs.h.
2201 (md_apply_fix): If an unconditional b or bal overflows, and we are
2202 not assembling PIC code, replace it with a j or jal.
2204 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
2205 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
2207 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2209 * write.c (write_relocs): Add file name and line number to
2210 as_fatal calls. Handle bfd_reloc_overflow case specifically when
2211 RELOC_EXPANSION_POSSIBLE.
2213 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2215 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
2216 here. Use them for deciding which PRINTF*LIKE macro definitions
2218 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
2219 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
2220 default definitions matching what we were doing before.
2221 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
2222 always use the varargs form if not using stdarg. It's safe to
2223 always use vfprintf, because libiberty will provide it if the
2224 native system doesn't. Also, always make format be const.
2225 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
2227 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

2240 (listing_newline): Check filename as well as line number when
2241 deciding whether to record it.
2242 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
2243 false (if defined) as well as checking for reg_section.
2244 (listing_listing): Iterate fetching lines while line number is too
2245 low, and we haven't run off the end of the input file.
2247 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
2249 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
2251 * ecoff.c (ecoff_generate_asm_lineno): check if
2252 current_stabs_filename is NULL before strcmp.
2253 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
2256 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2258 * config/ho-*.h: Now-unused files deleted.
2260 * symbols.c (copy_symbol_attributes): New function. Copies BFD
2261 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
2262 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
2263 zero. Don't call obj_frob_forward_symbol.
2264 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
2265 X_add_number is zero.
2266 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
2268 * config/tc-i960.c: Lots of whitespace, comment reformatting,
2270 (strchr): Don't declare.
2271 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
2272 md_estimate_size_before_relax, md_ri_to_chars,
2273 md_create_short_jump, md_create_long_jump.
2274 (brtab_emit): Use data_section, not SEG_DATA.
2276 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2278 * config/vms-conf.h: new file, manually derived from conf.in.
2279 * config-gas.com: use it, and eliminate obsolete "host.h".
2281 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2283 * config/tc-ppc.c (ppc_current_block): New static variable.
2284 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
2285 ppc_current_block. Don't move around any stab symbol, just those
2287 (ppc_bs): Set ppc_current_block.
2288 (ppc_es): Clear ppc_current_block.
2289 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
2290 from the csect of the enclosing block.
2292 * config/tc-mips.c (insns_since_cache_access): Remove.
2293 (append_insn): Remove setting of insns_since_cache_access, and
2294 special 4600 handling; it turns out not to be required.
2296 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2298 * config/tc-mips.c (md_shortopts): Remove E.
2299 (md_longopts): Add EB and EL.
2300 (md_parse_option): Handle -EB and -EL as separate options, rather
2301 than as a single -E option with an argument.
2303 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
2305 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
2306 involving global symbols too.
2308 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2310 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
2312 * configure.in: Test for remove, not delete. Fix cross-assembler
2314 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
2317 * read.c (pseudo_set, case O_symbol): If
2318 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
2319 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
2320 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
2322 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
2324 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
2325 many others): new macros; values obtained from "DSTRECRDS.SDL".
2326 * config/obj-vms.h (various): use them.
2327 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
2328 representation (only enum bitfields can avoid being bitstrings).
2329 (bitfield_suffix, setup_basic_type): new routines.
2330 (VMS_typedef_parse): use them. Now recognize bitfields of all
2331 integral types, not just type `int'. Caveat: the representation
2332 used for bitfields still does not work for objects placed in
2333 registers, and gcc's optimizer sometimes puts small structs there.
2335 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2337 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
2338 bit from const_flag.
2339 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
2340 (tc_frob_label): define this to call vms_check_for_special_label,
2341 and declare the latter.
2342 * config/obj-vms.c (vax_g_doubles): declare this file-scope
2344 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
2345 (vms_check_for_special_label): new routine (tc_frob_label).
2346 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
2347 and `gcc2_compiled.' labels; they won't reach here any more.
2348 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
2349 double', use `vax_g_doubles' flag to select type of double.
2350 (VMS_write_object_file) [traceback setup]: don't pass symbols
2351 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
2352 and TBT_Routine_End functions.
2354 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
2356 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
2357 S_GET_VALUE() to avoid many repeated function calls.
2358 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
2359 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
2360 gets requested. [All the HACK_DEC_C_STARTUP code appears to
2361 be obsolete; gcc does it automatically for vms target. It's
2362 also misnamed, because it is for the "VAX C" run-time library,
2363 not the newer "DEC C" one which has much different startup code.]
2364 {various}: use `S_SET_xxx(symbol,new_value)' rather than
2365 `S_GET_xxx(symbol) = new_value'.
2367 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

3366 Mon Jun 13 12:08:52 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3368 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
3369 to put a common symbol in a set.

3414 * read.c (emit_expr): Use memset to zero out memory, rather than
3415 going through md_number_to_chars. This permits handling symbolic

3468 m68040_control_regs, m68060_control_regs): New arrays.
3469 (control_regs): New pointer.
3470 (m68k_ip): Use control_regs instead of testing CPU every time.
3471 Use last_movec_reg too. In error messages, handle 68060, and
3472 print 68060 for mfloat, too.
3473 (m68k_init_after_args): Handle "68060". Use m68040up for making
3474 m68851 choice. Set control_regs.

3762 * listing.c (list_symbol_table): Print "NO DEFINED SYMBOLS" and
3763 "NO UNDEFINED SYMBOLS" if there aren't any, instead of displaying
3764 the header with an empty list.
3766 * config/obj-coffbfd.c (fill_section): Check COFF_NOLOAD_PROBLEM
3767 also before setting STYP_NOLOAD for .bss section.
3769 * config/tc-m68k.c (flag_reg_prefix_optional): New variable.
3770 Initialized to value of REGISTER_PREFIX_OPTIONAL, if defined, or
3772 (m68k_reg_parse): If flag_reg_prefix_optional is set, permit
3773 register prefix to be absent.
3774 (m68k_ip_op): Accept `&' also for immediate constants.
3775 (insert_reg): Don't bother with (two!?) sanity checks of the
3776 symbol table when inserting each register.

3778 flag_reg_prefix_optional if "register-prefix-optional" is passed.
3779 * config/tc-m68k.h (REGISTER_PREFIX): Always define if not already
3781 (OPTIONAL_REGISTER_PREFIX): Don't define.
3782 (REGISTER_PREFIX_OPTIONAL): If not already defined, define as zero

3786 * config/tc-m68k.c (DATA, ADDR, SP, FPREG, COPNUM, BAD, BAC):
3787 Define as macros instead of enumerators, since the Apollo compiler
3788 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum
3790 (make_pcrel_absolute) [NO_PCREL_RELOCS]: New function.
3791 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
3792 R_DIR16, and R_DIR32 relocs.
3793 * config/tc-m68k.h [TE_APOLLO] (COFF_MAGIC, COFF_AOUTHDR_MAGIC):
3794 Use Apollo versions.
3795 [TE_APOLLO] (OBJ_COFF_OMIT_OPTIONAL_HEADER): Undefine. That is,

3802 * config/tc-m68k.h (m68k_init_after_args): Declare.
3803 (tc_init_after_args): Define as m68k_init_after_args.
3804 * config/tc-m68k.c (m68k_init_after_args): New function,

3826 * listing.c (list_symbol_table): Don't print register symbols as
3829 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
3830 underscores, since symbol_new will already have done it.
3831 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
3833 * as.c (main): If tc_init_after_args is defined, invoke it after
3834 all arguments have been processed.
3836 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
3837 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
3838 section instead of .text. Call create_target_segments.
3839 * read.c (demand_copy_string): No longer static.
3841 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3843 * config/tc-mips.c (append_insn): Permit branches to be switched
3844 with the preceding instruction even if .set nobopt has been seen.
3845 .set nobopt actually controls whether to bring up an instruction
3846 from the branch target, which gas does not currently support.
3848 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3850 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

3897 (add_procedure): Set first_proc_ptr if it hasn't been set.
3898 (ecoff_build_lineno): If the first procedure does not start at
3899 address zero, insert a dummy line to compensate.
3901 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
3904 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3906 * expr.c (operand): Try to parse "0f" and "0b" sequences as
3907 floating point and binary numbers respectively; if it doesn't
3908 work, treat them as local labels.
3910 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
3911 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
3913 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
3915 * vmsconf.sh: In generated file, get ".obj" suffix right, build
3916 source files from other directories into objects in the current
3917 directory, and specify PSECT attributes explicitly to linker.
3918 Also added missing label.
3919 * Makefile.in (stamp-mk.com): Reference new variable

3937 argument, the reloc type.
3938 (load_register): Pass reloc type to macro_build for 'u'.
3939 (macro): Likewise. For M_LA_AB permit a difference expression
3940 when generating embedded PIC code between an arbitrary symbol and

3951 * subsegs.c (subsegs_begin): Call memset with args in the correct
3953 (subseg_get): Clear newly allocated seginfo, set its pointer slots

3983 (hppa_tc_symbol): Likewise.
3985 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
3986 elf_tc_make_sections stuff. It was there to support PA braindamage
3987 which has been fixed, and in the case of elf_tc_make_sections is
3988 redundant with elf_tc_final_processing.
3990 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3992 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

4008 don't spew remainder of input file in error message.
4009 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
4010 message with reloc type and try to process remainder of file.
4012 * doc/Makefile.in (install-info-as, install-info-gasp): New
4013 targets, now explicitly checking $(srcdir) for info files.
4014 (install-info): Depend on both of them; do nothing more.

4018 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
4020 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4022 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
4023 flag rather than signedp field. Only permit extended range if
4024 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
4025 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
4027 * config/tc-ppc.c (ppc_size): New static variable.
4028 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
4029 (md_begin): If an instruction has a size specific flag set, only
4030 add it if we are assembling that size.
4032 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4034 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
4035 cross section PC relative relocs right for COFF and ELF.
4037 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4039 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
4040 (OBJ_PROCESS_STAB): Don't define.

4044 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
4045 the type of symbol set symbols which happen to be in the absolute
4046 or undefined section.
4048 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
4050 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
4051 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
4052 and -many (all architectures).

4063 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
4065 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
4066 branch with an instruction that uses $at, in case the branch is
4068 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
4069 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
4070 to make it pcrel_offset.
4071 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
4072 reloc->address; another gruesome hack to get gas reloc handling to
4075 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4077 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
4080 (emit_insn): New function.
4081 (md_assemble): Call it.
4082 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
4084 (lituse_pending): New variable. Set by anything that generates a
4085 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
4086 tested by code that might want to emit a LITUSE reloc.
4087 (emit_unaligned_io): New function. Currently calls md_assemble,
4088 but it should eventually be converted to generate the insn itself
4089 and call emit_insn directly.
4090 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
4091 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
4092 emit_bis_r): Likewise.
4093 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
4094 (alpha_ip, label get_macro): Don't emit the final instruction if
4096 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
4097 unaligned memory access macros.
4098 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
4099 the value can't be resolved.
4101 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4103 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
4104 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

4117 * config/tc-mips.c (enum mips_pic_level): New enum.
4118 (mips_pic): Change from int to enum mips_pic_level. Change all
4119 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
4120 (load_address): Handle EMBEDDED_PIC.
4121 (macro): Handle EMBEDDED_PIC in all PIC cases.
4122 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
4123 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
4124 -non_shared to use NO_PIC (this is how the Irix 5 assembler
4125 works). Do not permit -G with SVR4_PIC.
4126 (s_abicalls): Warn if -G was used, and force -G 0.
4127 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
4128 anything but a.out, not just for ELF. For ECOFF, don't generate a
4129 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
4131 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
4133 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4135 * config/tc-hppa.c (create_new_space): Use ints, not chars as

4139 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4141 * Makefile.in (config-stamp): If `defs' is defined, emit a
4142 preprocessor directive to create a macro named by this value into
4143 config.new; don't explicitly go for BFD_ASSEMBLER.
4144 * configure.in: Define `defs', not `BFDDEF'. Set it to
4145 MANY_SEGMENTS for any obj-coffbfd target.
4146 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
4147 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
4149 (LOCAL_LOADLIBES): Deleted.
4150 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
4151 * config/m88kcoff.mt (TDEFINES): Ditto.
4152 * config/ebmon29k.mt: Deleted.
4153 * config/h8300hds.mt: Deleted.
4154 * config/ic960coff.mt: Deleted.
4155 * config/sparc.mt: Deleted.
4156 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
4157 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
4158 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
4159 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

4177 bfd_set_symtab is called.
4178 (dump_section_relocs): Note whether a symbol is a section symbol
4180 (adjust_reloc_syms): For now, always supply an absolute symbol for
4181 fixups without symbols but not yet `done'. Use section_symbol to
4182 get the symbol, instead of going directly for abs_symbol.
4183 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
4184 reloc is not a section symbol and is not in the symbol table.
4185 (set_symtab): New function, broken out from write_object_file.
4186 Counts symbol table instead of relying on an earlier count.
4187 (write_object_file): Call set_symtab, but do it after potentially
4188 invoking the *_frob_file macros. Don't bother counting symbols.
4189 Call symbol_remove, instead of expanding it in place. Moved the
4190 conditionalized `object_file_size' declaration down to
4191 conditionalized block where it's used. When using the absolute
4192 symbol for a fixup without a symbol, set sy_used_in_reloc.
4193 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
4194 the correct symbol for the absolute section.
4196 * subsegs.c (section_symbol): Use symbol_new instead of
4197 symbol_make, since we may want it to go into the symbol table.
4198 Make the new symbol have internal linkage. If
4199 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
4200 symbol with the newly created GAS symbol.

6076 pass new argument for i, j and o cases.
6077 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

6298 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
6299 the table, require that the one without bit 0x1000000 set come

6358 * write.c (write_relocs): For relocs that are pc_relative and
6359 pcrel_offset and not partial_inplace, adjust reloc->addend to

6410 OPTIONAL_REGISTER_PREFIX if either is already defined.
6412 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
6414 * configure.in: Set bfd_gas for all sparc targets. Added facility
6415 for keeping or rejecting configurations still under development;
6416 default is to assume production environment, and reject configs
6417 still being worked on. Mark Elf configurations (except sparc and
6418 i386) as developmental. Deleted cases matching some generic names
6419 in favor of more specific names. (E.g., when we get Alpha
6420 support, we'll still only support VMS for Vax.)

6436 through inclusion of tc-hppa.h. Delete all forward declarations
6437 for functions only used within tc-hppa.c, likewise for structures,
6438 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
6439 conditional code in a few small places.
6441 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
6442 structures, global variables, forward declarations together.
6443 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
6444 conditional code -- try to group conditional code together
6445 into a few places. Make all functions and variables which
6446 are only used within tc-hppa.c static. PARAMize all functions.
6447 Add comments to functions. Delete unused functions, variables,
6448 #defines, etc. Delete unused members within structures. Delete
6449 ldil;ble hacks -- it is believed they were installed to work
6450 around old gas bugs. Avoid using mixed case for local
6451 functions, variables, and structures. Fix formatting problems
6452 not found by GNU-indent. Add FIXME notices for things which
6453 should be worked on the near future. Delete lots of old
6454 useless (1.36 PA-SOM) code.
6456 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
6457 field of the fixS structure. Needed to build unwind
6458 descriptors correctly.

6483 a multiple of the section alignment rather than always a
6486 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
6487 bits are zero (eg they specify no relocations), then do not even
6488 bother adding their entries to thesymextn section.

6529 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
6530 call strchr for each character to see if it is a special char,
6531 instead add a second loop over special_chars. Set alignment
6532 of text, data and bss sections to 4.
6533 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
6535 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
6536 ELF, since the ELF object format does not have these type of
6537 relocations. Change the abort into as as_bad and return
6538 BFD_RELOC_NONE to silence compiler warnings.
6539 (md_assemble): Keep track of the instruction size. Allow white
6540 space between the $ and the constant for compatibility with older

7551 are also magic, and have special default flag settings.
7552 (obj_elf_frob_symbol): Since the return value from this function

7616 * Extensive changes to permit symbols to contain any expression
7617 type and to delay the computation of the expression until the
7618 value is actually needed. This permits setting symbols to values
7619 calculated based on object code size. Expressions were changed to
7620 no longer be in a section, to stop the overloading of segment and
7621 expression type that previously occurred.
7623 * as.c (big_section, pass1_section, diff_section, absent_section):
7625 (expr_section): Added (used for dummy symbols which hold

7709 (previous_section, previous_subsection): New vars.
7710 (obj_elf_section): Save current place in case DWARF code wants us
7711 to pop back to it. Handle unquoted section name as well as quoted
7712 section name. Don't crash on invalid strings.
7713 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

7825 sy_resolved and sy_resolving single bit fields.
7826 * symbols.c (symbol_new): Don't initialize sy_forward field.

8860 than ECOFF line number information.
8861 (obj_ecoff_stab): Accept non-zero values for stabs line number.

8888 references don't appear to work right.
8890 * as.h (const, volatile): Put these definitions back, and use
8893 * doc/as.texinfo: First pass at using new texinfo features --
8894 variables, conditional tests. Far from complete.

8920 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
8921 the bottom (make expands variables in dependencies when the
8922 dependencies are read, not when they are used).
8924 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
8925 a29k .bss section; the mondfe program doesn't like it.

8946 source directory, if that's not the current directory.
8948 * configure.in (per-host): Accept MIPS host with BSD version

8970 process relocs if there aren't any relocs to process. Avoids
8971 malloc/free bug on SCO too.
8973 * as.h: Move local include files below system include files, to
8974 avoid some redefinition complaints on some systems.
8975 (const, volatile): Don't need these conditionally defined if we
8976 use CONST and VOLATILE from ansidecl.h.
8977 (seg_name): Use CONST, not const.
8979 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
8981 * config/tc-mips.c: Reindented to GNU standards.
8983 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
8985 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
8986 (fixup_segment): Add a29k special case; the linker is not prepared
8987 to see a segment offset here.
8989 * app.c (do_scrub_next_char): Added new state, 10, modifying state
8990 9 to only keep a space in between identifier characters.
8992 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
8994 * Makefile.in: add dvi target; as-$(config).texinfo might live in
8995 srcdir, might be in objdir.

9015 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
9016 bignums, but don't emit error message.
9018 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
9020 * Makefile.in (targ-cpu.o): Depend on config.h.
9022 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
9024 * app.c (do_scrub_next_char): Added new state, 9, to avoid
9025 dropping a space immediately following an identifier.
9026 * expr.c, write.c: Rewrote assert expressions to not use multiple
9027 lines; I don't think that can be done portably.
9028 * config/tc-mips.c (macro): Use $AT if target register is zero in
9029 load instruction, which it can be for a floating point load.
9031 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

9042 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
9043 z8k-opc.h, not z8k.h.
9045 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
9048 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9050 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
9052 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
9054 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

9099 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
9100 (struct loc, struct proc, struct file): Moved to tc-mips.c within
9101 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
9102 * config/tc-mips.c: Rearranged for ECOFF support. Added
9103 prototypes for all static functions. Moved existing minimal
9104 debugging format support info #ifndef OBJ_ECOFF blocks.
9105 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
9106 does not support a non sign extended high 16 bits reloc. Adjusted
9107 all callers accordingly.
9108 (tc_get_register): Renamed from get_register, and made non-static.
9110 * config/mips-big.mt, config/mips-lit.mt: New files. Define

9153 * make-gas.com: Find obstack.obj if it's not in the current
9155 * read.c (s_ignore): Don't declare is_end_of_line. It's
9156 redundant, and triggers a VMS gcc compiler bug.
9158 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
9159 current segment as an argument. (Ignored in all cases but VMS.)
9160 All callers and definitions changed.

9176 (obj_elf_xstab): New routine.
9177 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
9178 argument to s_ignore. Put "#if 0" around unused code.
9179 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
9180 Call elf_xstabs for .stabs and .xstabs operators.
9182 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
9184 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
9187 * configure.in: mips-bsd configuration was missing format spec.
9190 * Makefile.in (Makefile): Depends on configure.in.
9192 * config/tc-mips.c (append_insn): Don't check for alignment of
9193 frag in memory; alignment of instructions in section is a separate
9196 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
9199 * listing.h: Always provide function declarations, not macros, so
9202 Tue Mar 2 00:50:43 1993 John Gilmore (gnu@cygnus.com)

9213 * config/tc-sparc.c (s_xword): Now call big_cons, so large
9214 constants are accepted, but symbolic values are not. GCC will not
9215 generate the latter currently.
9217 * frags.c (frag_init): New function.
9218 (zero_address_frag, bss_address_frag): Now initialized at run
9220 * as.c (main): Call frag_init.

9264 (fixup_segment): Make sure common-section symbols get treated the
9265 same as undefined symbols.
9266 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type
9267 bfd_reloc_code_real_type. Use seg_fix_{root,tail}P derived from

9274 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and
9277 * symbols.c (symbol_new): Argument NAME is now pointer to const.
9278 Simplified STRIP_UNDERSCORE code. Remove assumptions about null
9279 pointers in freshly allocated storage. [BFD_ASSEMBLER]: Get new

9296 new section/subsection.
9298 * read.c: Don't include ctype.h.
9299 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
9300 for now; should be machine-dependent.
9302 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
9303 targets, forcing BFD use.

9307 * config/tc-sparc.c: Use PARAMS macro for static function
9308 declarations. Use BFD_RELOC_ macros everywhere, with
9309 compatibility macros declared for non-BFD mode.
9310 (struct sparc_it) [BFD_ASSEMBLER]: Use bfd_reloc_code_real_type
9311 instead of enum reloc_type.

9321 of referencing fields directly.
9323 * write.c (cvt_frag_to_fill): New function; extracted from
9325 (write_object_file) [! BFD_ASSEMBLER]: Call it.
9326 (relax_and_size_seg) [BFD_ASSEMBLER]: New function; relax section
9327 and set its size and flags.
9329 * struc-symbol.h (struct symbol) [BFD_ASSEMBLER]: Replace some
9330 fields with BFD equivalents. Turn on back-pointers, and add

9473 latter, instead of selecting with preprocessor conditionals.
9475 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9477 * configure.in: recognise all sparclite variants

9487 * expr.c (operand): If character other than comma or newline is a
9488 logical end-of-line character, use the newline case.
9489 From Eric Youngdale:
9490 (operand): Set X_add_number field for floating-point numbers.
9491 (operand): Treat zero byte as end-of-operand.
9493 * configure.in (per-target): Look for with_bfd_assembler option.
9494 For now, only accept "no", until the merge is done.
9496 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
9497 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
9498 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
9499 * read.c: Finish conversion to S_* macros in the VMS only
9500 parts of the program. Add "const" modifier to hex_value.
9501 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
9503 * expr.c: Add "const" modifier to hex_value.
9504 * symbols.c: Finish conversion to S_* macros in the VMS only
9505 parts of the program. Add "const" modifier to
9506 md_[long,short]_jump_size. Remove declaration of const_flag
9507 (which will be declared in obj-vms.h).
9508 * write.c: Add "const" modifier to md_[long,short]_jump_size.
9509 Fix arguments to VMS_write_object_file.
9510 * config-gas.com: New file. Script for VMS systems to set up the
9511 configuration to build gas for VMS, and create config.status.
9512 * make-gas.com: Redone to work with new scheme.
9513 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
9515 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
9516 will swap bytes if needed on a big endian system. Use throughout
9518 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
9519 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
9520 types of malformed stabs. Change parsing algorithm so that we are
9521 more certain of having all of the information that we need on hand.
9522 * obj-vms.c (final_forward_reference): New function, used to help
9523 resolve the data types of as many struct elements as possible
9524 when some part of the struct is not fully defined by the compiler.

9527 * obj-vms.c (VMS_write_object_file): Define all vtable psects
9528 as symbols as well in the object file. Look for external functions

9530 g++ compiler is incapable of doing this.
9531 * tc-vax.c: Add '1' option for backward compatibility with older GCC
9533 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
9534 * input-scrub.c (as_where): Fix bug where as would crash if we did not
9535 have the name of the source file yet.
9536 * config/ho-vms.h: define HO_VMS, not HO_VAX.
9538 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
9540 * read.c (s_data): Always use "data_section", since it'll map to
9541 SEG_DATA or SEG_E1 if needed.
9542 (s_lcomm): Likewise with bss_section.
9543 (s_fill): Use memset, not bzero.
9545 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

9566 (section_alignment): Declare only if not BFD_ASSEMBLER.
9567 (big_section, reg_section, pass1_section, diff_section,
9568 absent_section, text_section, data_section, bss_section): If
9569 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
9570 mapping to segT enum values.
9571 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
9572 if these are used or defined, if BFD_ASSEMBLER.
9573 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
9574 subseg_new split into two functions.
9575 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
9577 * as.h (volatile): Don't define if already defined.
9578 (had_errors, had_warnings): Provide prototypes for ANSI C even if
9580 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
9581 declare with format attribute for -Wformat checking.
9583 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
9585 * app.c, config/tc-*.c: Don't include read.h, since it is already
9588 * These are based on patches from Minh Tran-le
9589 <mtranle@paris.intellicorp.com>.
9590 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
9591 obj_format coffbfd and gas_target i386coff for target.
9592 (i[34]86-*-isc*): New host (uses sysv).
9593 * config/i386aix.mt: Removed (no longer used).
9594 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
9596 (LDFLAGS): Added, defined as -shlib.
9597 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
9598 * config/te-sco386.h (LOCAL_LABEL): Don't define.
9599 (DOT_LABEL_PREFIX): Define.
9600 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
9601 name rather than L0\001.

9613 (size_section): Restored sanity check.
9614 (do_relocs_for): Base section address on s_paddr rather than
9615 computing it. Adjust a29k R_IHIHALF special case to account for
9616 section paddr (used to require paddr to be zero). If there are no
9617 reclos, set s_relptr to 0. Set relocation size in object_headers.
9618 (fill_section): Always set s_vaddr here, removing
9619 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
9620 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
9621 Set STYP_INFO for .comment.
9622 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
9623 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

9625 H_{SET,GET}_* macros.
9626 (do_linenos_for): Set lineno size in object_headers.
9627 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
9628 set s_vaddr here. If string_byte_count remains 4, set it back to
9629 0, and only write strings out if there are some. Call
9630 fill_section before do_relocs_for and do_linenos_for.
9631 (obj_coff_section): Handle optional quoted second argument giving
9632 section characteristics.
9633 (obj_coff_bss): Added to handle .bss.
9634 (obj_coff_ident): Added to handle .ident (puts string in .comment

9654 (do_scrub_next_char): For \", return " not '.
9655 (symbol_chars): Now const.
9657 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
9658 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
9660 * config/obj-coff.h: Don't use #elif.
9662 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
9663 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
9665 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
9667 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

9689 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
9690 using ZERO_BASED_SEGMENTS.
9691 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
9692 never set segment address for SEG_E2 (.bss) and don't write out
9693 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
9694 (obj_coff_endef): Don't merge labels or symbols awaiting forward
9695 definitions, and don't merge tags with non-tags. Check for .bf
9696 rather than just checking whether the second character is b and
9697 the third character is f.
9698 (obj_coff_val): gcc can generate values which we don't handle
9699 correctly; discard information for now, since it only affects the
9700 debugging information.

9702 (yank_symbols): Don't merge labels.
9703 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

9758 options. Updated options documentation for m68k. Some minor
9759 wording/punctuation changes.

9812 * xmalloc.c: Conditionalize on HAVE_MALLOC_H, not USG. Fold in
9813 xrealloc from xrealloc.c.
9814 * xrealloc.c: Deleted.
9815 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
9817 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
9820 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
9822 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;
9823 don't initialize it with NULL.

9844 * configure.in: No te-386bsd.h file exists; don't try to use it.
9846 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
9848 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
9849 could be doing emulation.
9851 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9854 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
9857 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
9859 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

9876 * obj-coffbfd.c (fill_section): set STYP_NOLOAD bit for .bss
9879 * atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,

9881 consistently const, and always initialized them. Included read.h.
9883 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
9885 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
9886 constant will not fit in an immediate field.
9887 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
9889 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
9891 * obj-coff.c (callj_table): Delete global variable.

9898 * obj-coff.c: Replaced ANSI and non-ANSI function declarations
9899 with a single set using PARAMS macro.
9901 * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length

9906 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
9907 so widening works consistently.
9909 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
9911 * version.c: Put conditional "const" before version_string, not
9912 before dummy function for VMS. Now version 1.91.03.
9914 * app.c (do_scrub_next_char): Need double-\ before `000' to show
9915 printed rep of null character.
9917 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
9919 * obj-coffbfd.c (write_object_file): check return value of
9922 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
9924 * Support for i386-sysv.
9925 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
9926 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
9927 be used to set them all to zero as was done before.
9928 (fill_section): segment addresses now set in write_object_file.
9929 (fill_section): Don't set STYP_NOLOAD for .bss section.
9930 (fixup_segment): 386 uses strange common symbol format.
9931 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
9932 compatibility with SVR3.2 linker.
9933 * configure.in: i386-sysv and i386-sco use coffbfd.
9935 * app.c (do_scrub_next_char): discard whitespace after a label.
9937 Sat Oct 10 12:33:45 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

9960 Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9962 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
9963 * tc-z8k.c: lots of bug fixes
9965 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
9967 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
9968 #elif, since it is not supported by old compilers.
9969 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
9970 couple of expressions in tc-m68k.c.
9972 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9974 * read.c (cons): If NO_RELOC is defined, use it.
9976 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
9978 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
9980 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
9981 local labels to start with a .) and set REGISTER_PREFIX to %.
9982 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
9984 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
9986 * messages.c: Comment changes.
9988 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

9991 * messages.c: If __STDC__ is not defined, define NO_STDARG.
9993 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
9995 * listing.c (debugging_pseudo): Add stabs and stabn as things to
9998 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
10000 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
10001 sections starting from zero, rather than making them consecutive.
10002 This makes subsequent reloc calculations easier, esp if the object
10003 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
10004 allocate lcomm in .data rather than in .bss. It seems that some
10005 tools can't cope with a non-zero sized bss before linkage.
10007 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10009 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10010 throughout. That enum no longer means what we thought it meant.
10012 * tc-m68k.c (md_assemble, md_parse_option): Handle new
10013 "-mno-688[58]1" options.
10015 * tc-m68k.c: Added CPU32 support.
10017 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10019 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
10021 Tue Sep 15 17:25:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
10023 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.

10028 * Makefile.in (install): if $(tooldir) exists, install as in
10031 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10033 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10034 .word is < -32768 or > 32767. The -J flag causes the error to be
10035 ignored. This is to catch over-sized switches generated by gcc on
10036 systems which don't support the broken .word hack.
10037 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10038 write.c (fixup_segment): check for signed .word overflow if
10039 WARN_SIGNED_OVERFLOW_WORD.
10041 * write.c (fixup_segment): fixed missing parens in expression
10042 checking for byte or word overflow.
10044 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
10045 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
10046 WARN_SIGNED_OVERFLOW_WORD.
10048 * obj-coffbfd.c (fixup_segment): fixed missing parens in
10049 expression checking for byte or word overflow.
10051 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10053 Support for i386 coff
10054 * obj-coffbfd.h : added stuff
10055 * tc-i386.c (tc_coff_fix2rtype): new function
10056 * tc-i386.h : new coff defines
10058 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
10060 * input-scrub.c (input_scrub_push): call input_file_begin, not
10062 messages.c (as_perror): print ": " between the passed in error and
10063 the strerror, like perror does.
10065 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
10067 * Makefile.in: use gas_target instead of modifying target_cpu.
10068 From Steve Chamberlain:
10069 Makefile.in: Handle m68*-*-coff*.

10072 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
10073 Motorola and MIT syntax; gas can now assemble either type of
10075 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
10076 From Steve Chamberlain:
10077 m68kcoff.mt: for m68k COFF.
10078 obj-coffbfd.c: (fixup_mdeps) added
10079 (size_section) removed bad sanity check
10080 (fill_section) added rs_machine_dependent case
10081 (write_object_file) call fixup_mdeps
10082 (fixup_segment) set fx_subsy to 0.
10083 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
10085 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
10088 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10090 * Makefile.in (LIBS): Include opcode library.
10092 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
10094 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
10095 including zero are accepted, pass +0.0.

10111 * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
10112 tc-i960.c (md_ri_to_chars): Always output bout object file in
10113 little endian byte order (used to use endianness of host).
10115 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10117 * config/tc-m68k.c (init_table): Now const. Always include 68851
10118 data, so that "bc" is available to 68040 cache instructions.
10119 Added "tt0", "tt1", and 68ec030 variants.
10120 (md_assemble): Complain if 68000 (only) and 68881 are specified.
10121 (enum _register): Added TT0, TT1.
10122 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
10123 line number correctly in "internal error" messages. Don't print
10124 architecture-mismatch message for operand errors.
10126 From Colin Smith (colin@wrs.com):
10127 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
10128 than install_operand.
10130 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10132 * listing.c (buffer_line): rewind to the start of include
10133 files, they might be included twice.
10135 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
10137 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
10139 * Makefile.in: defined TARGET_CPU for C code so that it can choose
10140 one element of a family.
10142 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
10144 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
10145 so that we can assemble hand-written libgcc code.
10147 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10149 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
10150 has already been formatted (but may still contain %-characters).
10151 (as_bad): Likewise.
10153 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
10155 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
10156 written with indirection on the last two operands, which can be
10157 either data or address registers. Added a new operand type 'r'
10158 which accepts either register type. Added '(' to notend stuff in
10159 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
10161 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
10163 * as.h (enum _relax_state): Start off at one, not zero, to better
10164 catch uninitialized-variable errors.
10165 (linkrelax): Declare new variable.
10167 * messages.c (warning_count, error_count): Default initializer is
10170 * write.c: Merged some declarations, using PARMS macro.

10172 data_last_frag): No longer static.
10173 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
10174 defined, call it. Change segments before calling fixup_segment.
10175 (relax_align): If linkrelax, provide extra padding.
10177 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
10178 their not having symbols associated.
10180 * tc-i960.c (norelax, instrument_branches): Default initializer is
10182 (linkrelax): Delete variable definition.
10183 (mem_fmt): Call fix_new with NO_RELOC.

10198 MINUS_G, set CFLAGS to default to -g, added FLAGS_TO_PASS, passed
10199 FLAGS_TO_PASS to recursive makes.
10201 * doc/Makefile.in: always create installation directories.
10203 Mon Aug 17 15:09:56 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10205 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
10206 being used with args swapped, causing occasional lossage when
10207 refilling buffers after an include file.
10209 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
10211 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
10212 version. Discard bogus DONTDEF version.
10213 (as_warn, as_bad, as_fatal): Likewise.
10215 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
10217 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
10218 selected architecture, print a message saying so and listing what
10219 processors support it, rather than saying "operands mismatch".
10221 Thu Aug 13 13:53:19 1992 Ken Raeburn (raeburn@cygnus.com)
10223 * as.h [BROKEN_ASSERT]: If defined, turn off all assertion checks.

10231 * sparc.mt: New file.
10233 Mon Aug 10 14:37:08 1992 Per Bothner (bothner@cygnus.com)
10235 * tc-m68k.c: ".align N" means align to N-byte boundary *only*
10236 if TN_SUN3; otherwise align to 2**N-byte bounary.
10238 Thu Aug 6 12:10:39 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10240 * read.c (s_fill): make the .fill size clamped error a warn and
10241 fix bug where 0's were always placed.
10243 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
10244 two bytes of any constant with 0xff:
10246 Wed Aug 5 12:02:40 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10248 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
10249 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.
10251 Wed Aug 5 01:54:34 1992 John Gilmore (gnu at cygnus.com)
10253 * tc-m68k.c (try_index): Error if index scaling specified and
10254 assembling for an older CPU than a 68020.
10256 Sat Aug 1 19:10:13 1992 Ken Raeburn (raeburn@cygnus.com)
10258 * config/tc-sparc.c (tc_aout_fix_to_chars): If pc-relative, take
10259 fx_offset into account.
10261 Fri Jul 31 21:53:28 1992 Ken Raeburn (raeburn@cygnus.com)
10263 * configure.in (mips host): Accept "ultrix" with version number.
10265 * expr.c (floating_constant): Separate "=-" to avoid confusing
10266 ancient or broken compilers.
10268 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
10269 processor/opcode mismatch, so reword the error message.
10270 (md_assemble): If no CPU has been set (even if FPU/PMMU
10271 characteristics have been), default to 68020. Don't need extra
10272 quotes around error string.
10274 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
10276 * read.c (potable): Revert sac's incorrect change made Jul 13.
10277 Align really is supposed to be ptwo not nbytes.
10279 Mon Jul 20 02:51:59 1992 D. V. Henkel-Wallace (gumby@cygnus.com)

10410 * Makefile.in (install): Install into $(tooldir)/bin, since that's
10411 where gcc looks for it.
10413 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
10415 * Makefile.in: Changed some lines to be less confusing for some

10455 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
10457 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

10481 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
10483 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
10485 * expr.c (operand): if can't work out what sort of operand it is,
10486 then look through FLT_CHARS for a hint.
10488 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
10490 * Makefile.in, configure.in: removed traces of namesubdir,
10491 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10492 copyrights to '92, changed some from Cygnus to FSF.
10494 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
10495 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10496 copyrights to '92, changed some from Cygnus to FSF.
10498 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10500 * expr.c: If an expression is single comma, then return with
10501 SEG_ABSENT rather than an error - since the sparc front end does
10502 really strange things with things like fbge,a
10504 * as.h: include bfd.h if using many sections
10505 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
10506 local labels didn't work.
10507 * listing.c (list_symbol_table): don't core dump when there's no
10509 * write.c, write.h: call fix_new with the right number of args on
10511 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
10514 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10516 * app.c: MRI compatibility - allow single quote to start a string.
10517 * as.c: fix typo recently introduced.
10518 * as.h : Don't include aout/reloc.h - it's not right for COFF!
10519 * expr.c: Much rewriting, to accomodate MRI syntax for
10520 expressions. Also easier to read now.
10521 * listing.c: Put back defuns
10522 * read.c: modified to accept MRI syntax, put back listing pseudo
10523 ops so that an assembler built with NO_LISTING ignores list ops
10525 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
10526 machine is a SPARC or a 29K.
10527 * config/obj-aout.c: added s_sect pseudo op
10528 * config/obj-coffbfd.c: lints, set the filehdr flags right and
10529 fill in the timestamp.
10530 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
10531 anymore, define all the relocs which the tc-<x> bit will use so we
10532 can translate from them to the coff types.
10533 * config/tc-a29k.c: reloc_type isn't ane enum any more
10534 * config/tc-m68k.c: Added NO_RELOC definition.
10536 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10538 * Makefile.in: put header files before C source for TAGS; remove
10539 references to non-existent syscalls.h.
10541 * read.c, write.c subsegs.c: back out the .bss changes.
10543 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
10545 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
10547 * a.out.h: removed.
10549 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
10551 * symbols.c (local_label_name): symbols now start with ^A.
10553 * read.c, subsegs.c, write.c obj-coff.c: added handling of
10554 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
10555 generate these sections. .align: will use NOP_OPCODE or 0
10556 for padding. This is just for being nice to the
10559 * expr.c (operand): changed to generate local label "\001L0"
10560 starting with a ^A so that it is recognized as a local label.
10562 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
10564 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
10565 i/o opcodes - inb, inw, outb and outw. string manipulation with
10566 att syntax - scmp, slod, smov, ssca, ssto.
10568 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
10569 to just after .file .
10571 In obj_crawl_symbol_chain() where it tries to put the external
10572 symbols apart, with the condition:
10573 (!S_IS_DEFINED(symbolP) &&
10574 !S_IS_DEBUG(symbolP) &&
10575 !SF_GET_STATICS(symbolP))
10576 it was moving too many symbols out. So I switch it back to the
10578 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
10580 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
10581 so that we don't use the F_RELFLG which make the linker complain
10582 that somebody has stripped the relocation info.
10584 Also, the AIX ld program require that the relocation table
10585 is sorted by r_vaddr like the standard ATT assembler does.
10587 [he also changed the sizeof(struct ...)'s into the coff
10588 style FOOSZ macros. I'm not sure this is right, but I can't
10589 remember why. xoxorich.]
10591 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
10593 * Makefile.in, configure.in, doc: use the doc. Build it, install
10596 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
10598 * read.c: white space and comments only.
10600 * configure.in: use the new atof-ns32.c for ns32k.
10602 * write.c: comment change only.
10604 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
10605 aren't yet integrated.
10607 * tc-i860.[hc]: blew off the dust. Something must still be done
10608 about conflicting relocation types.
10610 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
10613 * tc-i960.c, tc-sparc.c: white space and comments only.
10615 * tc-a29k.h: delete duplicate macro definition.
10617 * new file atof-ns32k.c copied from hack's last unreleased gas.
10619 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
10621 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
10624 * nearly everything. flush ChangeLog, package as gas-1.92.1.
10625 ChangeLog's prior to this are sketchy at best. I have logs.
10626 They just aren't ChangeLogs.
