4200 processing if add_symbol is undefined or in expr_section.
4201 (resolve_symbol_value, case O_add): For symbol plus
4202 constant-valued symbol, convert to O_symbol and re-reduce.

4204 (indent_level): No longer static.
4205 (print_symbol_value_1): Don't print frag address if it matches
4206 zero_address_frag. Don't print "resolving" if already resolved.

4209 (print_expr_1): Fix whitespace before printing X_add_number.
4211 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
4212 not symbol_new, for symbols holding expression values.
4213 * expr.h (make_expr_symbol): Move declaration here.
4214 * write.c (fix_new_exp): Handle O_add by creating an
4215 expression-valued symbol, and calling fix_new_exp recursively.
4216 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
4217 undefined symbol and a constant, fold the constant into the fixup,
4218 and refer to the undefined symbol directly. Then process the
4219 fixup again from scratch.
4220 (write_object_file): Before calling adjust_reloc_syms, make a pass
4221 through the symbol list trying to resolve values.
4223 * write.c (print_fixup): New routine, for debugging.
4224 (write_relocs): Call bfd_install_relocation. Deleted various
4225 hacks for working around problems with bfd_perform_relocation.
4227 * Makefile.in (VERSION): Update to 2.4.90.

4233 * config/tc-mips.c: Include subsegs.h.
4234 (md_apply_fix): If an unconditional b or bal overflows, and we are
4235 not assembling PIC code, replace it with a j or jal.
4237 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
4238 Use as_bad_where and as_warn_where rather than as_bad and as_warn.

4242 * write.c (write_relocs): Add file name and line number to
4243 as_fatal calls. Handle bfd_reloc_overflow case specifically when

4246 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4248 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
4249 here. Use them for deciding which PRINTF*LIKE macro definitions
4251 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
4252 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
4253 default definitions matching what we were doing before.
4254 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
4255 always use the varargs form if not using stdarg. It's safe to
4256 always use vfprintf, because libiberty will provide it if the
4257 native system doesn't. Also, always make format be const.
4258 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
4260 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

4274 deciding whether to record it.
4275 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
4276 false (if defined) as well as checking for reg_section.
4277 (listing_listing): Iterate fetching lines while line number is too
4278 low, and we haven't run off the end of the input file.
4280 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
4282 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
4284 * ecoff.c (ecoff_generate_asm_lineno): check if
4285 current_stabs_filename is NULL before strcmp.
4286 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
4289 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4291 * config/ho-*.h: Now-unused files deleted.
4293 * symbols.c (copy_symbol_attributes): New function. Copies BFD
4294 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
4295 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
4296 zero. Don't call obj_frob_forward_symbol.
4297 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
4298 X_add_number is zero.
4299 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
4301 * config/tc-i960.c: Lots of whitespace, comment reformatting,
4303 (strchr): Don't declare.
4304 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
4305 md_estimate_size_before_relax, md_ri_to_chars,
4306 md_create_short_jump, md_create_long_jump.
4307 (brtab_emit): Use data_section, not SEG_DATA.
4309 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
4311 * config/vms-conf.h: new file, manually derived from conf.in.
4312 * config-gas.com: use it, and eliminate obsolete "host.h".

4316 * config/tc-ppc.c (ppc_current_block): New static variable.
4317 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to

4321 (ppc_es): Clear ppc_current_block.
4322 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
4323 from the csect of the enclosing block.
4325 * config/tc-mips.c (insns_since_cache_access): Remove.
4326 (append_insn): Remove setting of insns_since_cache_access, and
4327 special 4600 handling; it turns out not to be required.
4329 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4331 * config/tc-mips.c (md_shortopts): Remove E.
4332 (md_longopts): Add EB and EL.
4333 (md_parse_option): Handle -EB and -EL as separate options, rather
4334 than as a single -E option with an argument.

4343 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
4345 * configure.in: Test for remove, not delete. Fix cross-assembler
4347 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
4350 * read.c (pseudo_set, case O_symbol): If
4351 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
4352 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
4353 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
4355 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
4357 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
4358 many others): new macros; values obtained from "DSTRECRDS.SDL".
4359 * config/obj-vms.h (various): use them.
4360 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
4361 representation (only enum bitfields can avoid being bitstrings).
4362 (bitfield_suffix, setup_basic_type): new routines.
4363 (VMS_typedef_parse): use them. Now recognize bitfields of all
4364 integral types, not just type `int'. Caveat: the representation
4365 used for bitfields still does not work for objects placed in
4366 registers, and gcc's optimizer sometimes puts small structs there.
4368 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
4370 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
4371 bit from const_flag.
4372 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
4373 (tc_frob_label): define this to call vms_check_for_special_label,
4374 and declare the latter.
4375 * config/obj-vms.c (vax_g_doubles): declare this file-scope
4377 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
4378 (vms_check_for_special_label): new routine (tc_frob_label).
4379 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
4380 and `gcc2_compiled.' labels; they won't reach here any more.
4381 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
4382 double', use `vax_g_doubles' flag to select type of double.
4383 (VMS_write_object_file) [traceback setup]: don't pass symbols
4384 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
4385 and TBT_Routine_End functions.

4389 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
4390 S_GET_VALUE() to avoid many repeated function calls.
4391 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
4392 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
4393 gets requested. [All the HACK_DEC_C_STARTUP code appears to
4394 be obsolete; gcc does it automatically for vms target. It's
4395 also misnamed, because it is for the "VAX C" run-time library,
4396 not the newer "DEC C" one which has much different startup code.]
4397 {various}: use `S_SET_xxx(symbol,new_value)' rather than
4398 `S_GET_xxx(symbol) = new_value'.
4400 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4402 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
4403 not &bfd_abs_section.
4405 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4407 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
4409 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
4411 * expr.c (expr): Don't reduce the difference of two symbols in the
4412 same frag if the symbols are not in normal sections.
4414 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
4415 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
4416 (obj_attach_unwind_info): Do not define. Not needed anymore.
4417 * config/tc-hppa.c: Delete whitespace at EOL.
4418 (struct hppa_fix_struct): Delete fx_unwind field and all references.
4419 (fix_new_hppa): Last arg is now a pointer to an int. Do not
4420 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
4421 fixups, store 32bits of unwind information in the fx_addnumber
4423 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
4424 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
4425 pointer to 32 bits of unwind info.
4426 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
4427 pointer to the dummy symbol; set the addend field to fx_addnumber.
4428 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
4429 rather than &bfd_XXX_section.
4431 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4433 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
4434 value by one; discard adjustments previously being made. From
4437 VMS- and Vax-related changes from Pat Rankin:
4438 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
4439 * vmsconf.sh: no longer have make-gas.com echo text about needing
4440 to modify the gcc-vms driver when intending to use with gcc 1.x.
4441 * as.c (parse_options): suppress 'v' from std_short_options and
4442 eliminate VMS-specific conditional initialization;
4443 [default case]: check for '-v' if md_parse_options doesn't recognize
4445 [default case, #if VMS]: check for filename argument when '-v' seen;
4447 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
4448 for O_big literal operands (double floats and long long ints);
4449 [VMS, md_shortopts]: add second colon after 'v';
4450 (md_parse_options) [VMS, case 'v']: check for argument, so
4451 caller can handle `-v' w/o arg.

4509 to ensure that older versions of autoconf aren't used.
4510 * Makefile.in: Added @configure_input@ line.
4511 (configure): Deleted rule.

4515 * config/obj-coff.c (fixup_segment): After handling the difference
4516 of two symbols from the same segment, set fx_subsy to NULL, to
4517 satisfy existing TC_COUNT_RELOC macros.

4592 reportedly to be used on Irix 6.
4594 * config/tc-mips.c (md_pseudo_table): Handle .globl and .global.
4595 (s_mips_globl): New static function; needed for Irix 5 support.
4596 * ecoff.c (ecoff_build_symbols): If BSF_FUNCTION is set for an
4597 external symbol with no type, set the type to st_Proc rather than

5575 VMS debugger now recognizes `long long' variables correctly.
5576 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
5577 for gcc2's predefined types "long double" (same as double, as
5578 per gcc's current state), "long long int", "long long unsigned
5579 int", and final `otherwise' case (to avoid uninitialized type
5580 and size fields). [caveat: predefined types "complex int",
5581 "complex float", "complex double", and "complex long double" are
5584 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
5585 of 0, because the latter indicates success rather than failure
5586 when passed to `exit' or return from `main' compiled by gcc2.

5589 hardcoded `0xa3's with macro DBG_S_C_ADVANCED_TYPE from obj-vms.h.

5949 source files from other directories into objects in the current
5950 directory, and specify PSECT attributes explicitly to linker.
5951 Also added missing label.

6040 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
6041 don't spew remainder of input file in error message.
6042 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
6043 message with reloc type and try to process remainder of file.
6045 * doc/Makefile.in (install-info-as, install-info-gasp): New
6046 targets, now explicitly checking $(srcdir) for info files.
6047 (install-info): Depend on both of them; do nothing more.

6055 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
6056 flag rather than signedp field. Only permit extended range if
6057 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
6058 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
6060 * config/tc-ppc.c (ppc_size): New static variable.
6061 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
6062 (md_begin): If an instruction has a size specific flag set, only
6063 add it if we are assembling that size.
6065 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6067 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
6068 cross section PC relative relocs right for COFF and ELF.
6070 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

6077 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
6078 the type of symbol set symbols which happen to be in the absolute
6079 or undefined section.

6083 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
6084 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
6085 and -many (all architectures).
6087 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

6096 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
6098 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
6099 branch with an instruction that uses $at, in case the branch is
6101 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
6102 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
6103 to make it pcrel_offset.
6104 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
6105 reloc->address; another gruesome hack to get gas reloc handling to
6108 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6110 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
6113 (emit_insn): New function.
6114 (md_assemble): Call it.
6115 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
6117 (lituse_pending): New variable. Set by anything that generates a
6118 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
6119 tested by code that might want to emit a LITUSE reloc.
6120 (emit_unaligned_io): New function. Currently calls md_assemble,
6121 but it should eventually be converted to generate the insn itself
6122 and call emit_insn directly.
6123 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
6124 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
6125 emit_bis_r): Likewise.

6132 the value can't be resolved.
6134 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6136 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
6137 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
6138 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
6140 (mips_force_relocation): New function.
6141 (md_apply_fix): Set fixP->fx_done appropriately.
6142 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

6150 * config/tc-mips.c (enum mips_pic_level): New enum.
6151 (mips_pic): Change from int to enum mips_pic_level. Change all
6152 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
6153 (load_address): Handle EMBEDDED_PIC.
6154 (macro): Handle EMBEDDED_PIC in all PIC cases.
6155 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
6156 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
6157 -non_shared to use NO_PIC (this is how the Irix 5 assembler
6158 works). Do not permit -G with SVR4_PIC.
6159 (s_abicalls): Warn if -G was used, and force -G 0.
6160 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
6161 anything but a.out, not just for ELF. For ECOFF, don't generate a
6162 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
6164 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
6166 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6168 * config/tc-hppa.c (create_new_space): Use ints, not chars as
6169 parameters to avoid losing when compiling with HP CC.
6170 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
6172 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6174 * Makefile.in (config-stamp): If `defs' is defined, emit a
6175 preprocessor directive to create a macro named by this value into
6176 config.new; don't explicitly go for BFD_ASSEMBLER.
6177 * configure.in: Define `defs', not `BFDDEF'. Set it to
6178 MANY_SEGMENTS for any obj-coffbfd target.
6179 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
6180 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
6182 (LOCAL_LOADLIBES): Deleted.
6183 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
6184 * config/m88kcoff.mt (TDEFINES): Ditto.
6185 * config/ebmon29k.mt: Deleted.

6188 * config/sparc.mt: Deleted.
6189 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

6210 bfd_set_symtab is called.
6211 (dump_section_relocs): Note whether a symbol is a section symbol
6213 (adjust_reloc_syms): For now, always supply an absolute symbol for
6214 fixups without symbols but not yet `done'. Use section_symbol to
6215 get the symbol, instead of going directly for abs_symbol.
6216 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
6217 reloc is not a section symbol and is not in the symbol table.
6218 (set_symtab): New function, broken out from write_object_file.
6219 Counts symbol table instead of relying on an earlier count.
6220 (write_object_file): Call set_symtab, but do it after potentially
6221 invoking the *_frob_file macros. Don't bother counting symbols.
6222 Call symbol_remove, instead of expanding it in place. Moved the
6223 conditionalized `object_file_size' declaration down to
6224 conditionalized block where it's used. When using the absolute
6225 symbol for a fixup without a symbol, set sy_used_in_reloc.
6226 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
6227 the correct symbol for the absolute section.
6229 * subsegs.c (section_symbol): Use symbol_new instead of
6230 symbol_make, since we may want it to go into the symbol table.
6231 Make the new symbol have internal linkage. If
6232 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
6233 symbol with the newly created GAS symbol.
6234 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
6235 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

6240 (in_signed_range): New function.
6242 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
6243 (sparc_ip, label "immediate"): Reject constants for pcrel
6244 instructions only if the relocation type indicates a "call"
6245 instruction and the offset is within range of a "jmpl %g0". If
6246 it's not in range, use the absolute section symbol plus an offset.
6247 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
6249 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
6251 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
6254 * configure.in: Eliminated all targets using obj-coff but not
6255 defining BFD_ASSEMBLER; I think all such targets that are
6256 supported will be matched by real CPU-OS combinations earlier in
6258 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
6259 some comments about the dpx2 configuration, but left it disabled,
6260 since it couldn't be reached before.
6261 (target a29k-amd-ebmonold): Deleted.
6263 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

6271 the 'j' operand if there are no further alternatives for this
6274 * config/obj-coffbfd.c (adjust_stab_section): Initialize
6275 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
6276 is not SEG_UNKNOWN rather than checking whether it is >= 0.
6278 * config/tc-mips.c (mips_align): Take new argument, label, and use
6279 it instead of global insn_label.
6280 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
6281 call to mips_emit_delay and pass it to mips_align.
6283 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6285 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
6287 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
6288 argument to a .callinfo directive. Don't loop forever on errors.
6290 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
6291 use pre-defined registers as arguments.

6295 * write.c (write_object_file): Check both S_IS_LOCAL and
6296 S_IS_EXTERNAL when deciding whether to discard a symbol.
6298 * config-gas.com: Scan Makefile.in, not version.c, for current
6299 version number. Delete all versions of temp files when finished
6300 with them. Create config.h.
6302 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
6303 values to reduce number of lookups with S_GET_VALUE. Skip debug
6304 symbols to avoid "a really nasty bug". (From Holger Teutsch,
6305 holger@botbso.rhein-main.de.)
6306 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
6307 field. (Also from Holger Teutsch.) Watch for a would-be register
6308 mask that spans frags.
6310 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
6311 this_base, not line_base. (Patch from Andreas Arens,
6312 ari@obelix.av.rwth-aachen.de.)
6314 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
6315 look local if they're exported or undefined. Used to be done for
6318 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
6319 Get it from the looked-up symbol, instead of using the string from
6320 the input stream, which is no longer null-terminated.
6321 (LEX_PCT): New macro, defaults to 0.
6322 (lex_type): Use it for `%'.
6324 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
6325 (vip_op): Now static, and returns void. Callers changed. Added
6327 (vip): Ditto. Call as_fatal directly if a program bug is

6374 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
6375 0xffff for 'j' to be compatible with MIPS assembler. These

6465 (tc_bout_fix_to_chars): Store symbol index for all callx
6466 relocations, regardless of link-relax setting.

8448 for keeping or rejecting configurations still under development;
8449 default is to assume production environment, and reject configs
8450 still being worked on. Mark Elf configurations (except sparc and
8451 i386) as developmental. Deleted cases matching some generic names
8452 in favor of more specific names. (E.g., when we get Alpha

8478 into a few places. Make all functions and variables which
8479 are only used within tc-hppa.c static. PARAMize all functions.
8480 Add comments to functions. Delete unused functions, variables,
8481 #defines, etc. Delete unused members within structures. Delete
8482 ldil;ble hacks -- it is believed they were installed to work
8483 around old gas bugs. Avoid using mixed case for local
8484 functions, variables, and structures. Fix formatting problems
8485 not found by GNU-indent. Add FIXME notices for things which
8486 should be worked on the near future. Delete lots of old
8487 useless (1.36 PA-SOM) code.

8507 of elf32_symbol_type.
8508 (pa_export_args): Likewise.

8516 a multiple of the section alignment rather than always a
8519 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

8566 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
8568 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
8569 ELF, since the ELF object format does not have these type of
8570 relocations. Change the abort into as as_bad and return
8571 BFD_RELOC_NONE to silence compiler warnings.
8572 (md_assemble): Keep track of the instruction size. Allow white
8573 space between the $ and the constant for compatibility with older
8574 gases and other assemblers.

11007 avoid some redefinition complaints on some systems.
11008 (const, volatile): Don't need these conditionally defined if we
11009 use CONST and VOLATILE from ansidecl.h.
11010 (seg_name): Use CONST, not const.

11058 dropping a space immediately following an identifier.

11136 prototypes for all static functions. Moved existing minimal
11137 debugging format support info #ifndef OBJ_ECOFF blocks.

11186 * make-gas.com: Find obstack.obj if it's not in the current
11188 * read.c (s_ignore): Don't declare is_end_of_line. It's
11189 redundant, and triggers a VMS gcc compiler bug.
11191 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
11192 current segment as an argument. (Ignored in all cases but VMS.)
11193 All callers and definitions changed.

11557 when some part of the struct is not fully defined by the compiler.
11558 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
11560 * obj-vms.c (VMS_write_object_file): Define all vtable psects
11561 as symbols as well in the object file. Look for external functions
11562 that start with "__vt.", and turn them into variables, since the
11563 g++ compiler is incapable of doing this.
11564 * tc-vax.c: Add '1' option for backward compatibility with older GCC
11566 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
11567 * input-scrub.c (as_where): Fix bug where as would crash if we did not
11568 have the name of the source file yet.

11571 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
11573 * read.c (s_data): Always use "data_section", since it'll map to
11574 SEG_DATA or SEG_E1 if needed.
11575 (s_lcomm): Likewise with bss_section.
11576 (s_fill): Use memset, not bzero.
11578 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

11597 otherwise, use seg_name array.
11598 (seg_name): Declare only if not BFD_ASSEMBLER.
11599 (section_alignment): Declare only if not BFD_ASSEMBLER.
11600 (big_section, reg_section, pass1_section, diff_section,
11601 absent_section, text_section, data_section, bss_section): If
11602 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
11603 mapping to segT enum values.
11604 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
11605 if these are used or defined, if BFD_ASSEMBLER.
11606 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
11607 subseg_new split into two functions.
11608 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
11610 * as.h (volatile): Don't define if already defined.

11614 declare with format attribute for -Wformat checking.
11616 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
11618 * app.c, config/tc-*.c: Don't include read.h, since it is already
11621 * These are based on patches from Minh Tran-le
11622 <mtranle@paris.intellicorp.com>.
11623 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
11624 obj_format coffbfd and gas_target i386coff for target.
11625 (i[34]86-*-isc*): New host (uses sysv).
11626 * config/i386aix.mt: Removed (no longer used).
11627 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
11628 (MINUS_G): Removed.
11629 (LDFLAGS): Added, defined as -shlib.
11630 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
11631 * config/te-sco386.h (LOCAL_LABEL): Don't define.
11632 (DOT_LABEL_PREFIX): Define.
11633 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
11634 name rather than L0\001.
11635 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
11637 * symbols.c, symbols.h (local_bss_counter): Removed.
11638 * write.c (write_object_file): bss no longer uses
11639 local_bss_counter. Pass correct data and bss size to
11640 VMS_write_object_file.

11646 (size_section): Restored sanity check.
11647 (do_relocs_for): Base section address on s_paddr rather than
11648 computing it. Adjust a29k R_IHIHALF special case to account for
11649 section paddr (used to require paddr to be zero). If there are no
11650 reclos, set s_relptr to 0. Set relocation size in object_headers.
11651 (fill_section): Always set s_vaddr here, removing
11652 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
11653 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
11654 Set STYP_INFO for .comment.
11655 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
11656 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

11658 H_{SET,GET}_* macros.
11659 (do_linenos_for): Set lineno size in object_headers.
11660 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
11661 set s_vaddr here. If string_byte_count remains 4, set it back to
11662 0, and only write strings out if there are some. Call
11663 fill_section before do_relocs_for and do_linenos_for.
11664 (obj_coff_section): Handle optional quoted second argument giving
11665 section characteristics.
11666 (obj_coff_bss): Added to handle .bss.
11667 (obj_coff_ident): Added to handle .ident (puts string in .comment

11687 (do_scrub_next_char): For \", return " not '.
11688 (symbol_chars): Now const.
11690 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
11691 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
11693 * config/obj-coff.h: Don't use #elif.
11695 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
11696 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
11698 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
11700 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

11722 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
11723 using ZERO_BASED_SEGMENTS.
11724 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
11725 never set segment address for SEG_E2 (.bss) and don't write out
11726 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
11727 (obj_coff_endef): Don't merge labels or symbols awaiting forward
11728 definitions, and don't merge tags with non-tags. Check for .bf
11729 rather than just checking whether the second character is b and
11730 the third character is f.
11731 (obj_coff_val): gcc can generate values which we don't handle
11732 correctly; discard information for now, since it only affects the
11733 debugging information.

11735 (yank_symbols): Don't merge labels.
11736 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

12001 #elif, since it is not supported by old compilers.
12002 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
12003 couple of expressions in tc-m68k.c.
12005 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

12014 local labels to start with a .) and set REGISTER_PREFIX to %.
12015 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
12017 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

12033 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
12034 sections starting from zero, rather than making them consecutive.
12035 This makes subsequent reloc calculations easier, esp if the object
12036 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
12037 allocate lcomm in .data rather than in .bss. It seems that some
12038 tools can't cope with a non-zero sized bss before linkage.

12042 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
12043 throughout. That enum no longer means what we thought it meant.
12045 * tc-m68k.c (md_assemble, md_parse_option): Handle new
12046 "-mno-688[58]1" options.

12064 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
12066 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
12067 .word is < -32768 or > 32767. The -J flag causes the error to be
12068 ignored. This is to catch over-sized switches generated by gcc on
12069 systems which don't support the broken .word hack.
12070 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
12071 write.c (fixup_segment): check for signed .word overflow if
12072 WARN_SIGNED_OVERFLOW_WORD.

12113 (fill_section) added rs_machine_dependent case
12114 (write_object_file) call fixup_mdeps
12115 (fixup_segment) set fx_subsy to 0.
12116 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
12118 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
12121 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

12150 * config/tc-m68k.c (init_table): Now const. Always include 68851
12151 data, so that "bc" is available to 68040 cache instructions.
12152 Added "tt0", "tt1", and 68ec030 variants.
12153 (md_assemble): Complain if 68000 (only) and 68881 are specified.

12155 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
12156 line number correctly in "internal error" messages. Don't print
12157 architecture-mismatch message for operand errors.

12178 so that we can assemble hand-written libgcc code.
12180 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
12182 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
12183 has already been formatted (but may still contain %-characters).
12184 (as_bad): Likewise.
12186 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
12188 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
12189 written with indirection on the last two operands, which can be
12190 either data or address registers. Added a new operand type 'r'
12191 which accepts either register type. Added '(' to notend stuff in
12192 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

12485 * symbols.c: remove local_labels_dollar, replace with a function
12486 interface for a sparse array. All users adjusted.
12488 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
12490 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
12492 * doc/Makefile.in: commented out line for building as-all.texinfo.
12495 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
12497 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
12499 * Makefile.in: added check target.
12501 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
12503 * Makefile.in: added tooldir and program_prefix.
12505 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
12507 * write.{c,h} (fix_new): Make these declarations consistent.
12509 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
12511 * Makefile.in (strerror.o): Add rule so that broken Sun make can
12514 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
12516 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
12518 * expr.c (operand): if can't work out what sort of operand it is,
12519 then look through FLT_CHARS for a hint.
12521 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
12523 * Makefile.in, configure.in: removed traces of namesubdir,
12524 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
12525 copyrights to '92, changed some from Cygnus to FSF.
12527 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
12528 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
12529 copyrights to '92, changed some from Cygnus to FSF.
12531 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
12533 * expr.c: If an expression is single comma, then return with
12534 SEG_ABSENT rather than an error - since the sparc front end does
12535 really strange things with things like fbge,a
12537 * as.h: include bfd.h if using many sections
12538 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
12539 local labels didn't work.
12540 * listing.c (list_symbol_table): don't core dump when there's no
12542 * write.c, write.h: call fix_new with the right number of args on
12544 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
12547 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
12549 * app.c: MRI compatibility - allow single quote to start a string.
12550 * as.c: fix typo recently introduced.
12551 * as.h : Don't include aout/reloc.h - it's not right for COFF!
12552 * expr.c: Much rewriting, to accomodate MRI syntax for
12553 expressions. Also easier to read now.
12554 * listing.c: Put back defuns
12555 * read.c: modified to accept MRI syntax, put back listing pseudo
12556 ops so that an assembler built with NO_LISTING ignores list ops
12558 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
12559 machine is a SPARC or a 29K.
12560 * config/obj-aout.c: added s_sect pseudo op
12561 * config/obj-coffbfd.c: lints, set the filehdr flags right and
12562 fill in the timestamp.
12563 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
12564 anymore, define all the relocs which the tc-<x> bit will use so we
12565 can translate from them to the coff types.
12566 * config/tc-a29k.c: reloc_type isn't ane enum any more
12567 * config/tc-m68k.c: Added NO_RELOC definition.
12569 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
12571 * Makefile.in: put header files before C source for TAGS; remove
12572 references to non-existent syscalls.h.
12574 * read.c, write.c subsegs.c: back out the .bss changes.
12576 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
12578 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
12580 * a.out.h: removed.
12582 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
12584 * symbols.c (local_label_name): symbols now start with ^A.
12586 * read.c, subsegs.c, write.c obj-coff.c: added handling of
12587 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
12588 generate these sections. .align: will use NOP_OPCODE or 0
12589 for padding. This is just for being nice to the
12592 * expr.c (operand): changed to generate local label "\001L0"
12593 starting with a ^A so that it is recognized as a local label.
12595 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
12597 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
12598 i/o opcodes - inb, inw, outb and outw. string manipulation with
12599 att syntax - scmp, slod, smov, ssca, ssto.
12601 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
12602 to just after .file .
12604 In obj_crawl_symbol_chain() where it tries to put the external
12605 symbols apart, with the condition:
12606 (!S_IS_DEFINED(symbolP) &&
12607 !S_IS_DEBUG(symbolP) &&
12608 !SF_GET_STATICS(symbolP))
12609 it was moving too many symbols out. So I switch it back to the
12611 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
12613 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
12614 so that we don't use the F_RELFLG which make the linker complain
12615 that somebody has stripped the relocation info.
12617 Also, the AIX ld program require that the relocation table
12618 is sorted by r_vaddr like the standard ATT assembler does.
12620 [he also changed the sizeof(struct ...)'s into the coff
12621 style FOOSZ macros. I'm not sure this is right, but I can't
12622 remember why. xoxorich.]
12624 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
12626 * Makefile.in, configure.in, doc: use the doc. Build it, install
12629 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
12631 * read.c: white space and comments only.
12633 * configure.in: use the new atof-ns32.c for ns32k.
12635 * write.c: comment change only.
12637 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
12638 aren't yet integrated.
12640 * tc-i860.[hc]: blew off the dust. Something must still be done
12641 about conflicting relocation types.
12643 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
12646 * tc-i960.c, tc-sparc.c: white space and comments only.
12648 * tc-a29k.h: delete duplicate macro definition.
12650 * new file atof-ns32k.c copied from hack's last unreleased gas.
12652 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
12654 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
12657 * nearly everything. flush ChangeLog, package as gas-1.92.1.
12658 ChangeLog's prior to this are sketchy at best. I have logs.
12659 They just aren't ChangeLogs.
