4191 not assembling PIC code, replace it with a j or jal.
4193 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
4194 Use as_bad_where and as_warn_where rather than as_bad and as_warn.

4198 * write.c (write_relocs): Add file name and line number to
4199 as_fatal calls. Handle bfd_reloc_overflow case specifically when
4200 RELOC_EXPANSION_POSSIBLE.
4202 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4204 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
4205 here. Use them for deciding which PRINTF*LIKE macro definitions
4207 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
4208 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
4209 default definitions matching what we were doing before.
4210 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
4211 always use the varargs form if not using stdarg. It's safe to
4212 always use vfprintf, because libiberty will provide it if the
4213 native system doesn't. Also, always make format be const.
4214 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
4216 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

4230 deciding whether to record it.
4231 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
4232 false (if defined) as well as checking for reg_section.
4233 (listing_listing): Iterate fetching lines while line number is too
4234 low, and we haven't run off the end of the input file.
4236 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
4238 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
4240 * ecoff.c (ecoff_generate_asm_lineno): check if
4241 current_stabs_filename is NULL before strcmp.
4242 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
4245 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4247 * config/ho-*.h: Now-unused files deleted.
4249 * symbols.c (copy_symbol_attributes): New function. Copies BFD
4250 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
4251 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
4252 zero. Don't call obj_frob_forward_symbol.
4253 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
4254 X_add_number is zero.
4255 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
4257 * config/tc-i960.c: Lots of whitespace, comment reformatting,
4259 (strchr): Don't declare.
4260 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
4261 md_estimate_size_before_relax, md_ri_to_chars,
4262 md_create_short_jump, md_create_long_jump.
4263 (brtab_emit): Use data_section, not SEG_DATA.
4265 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
4267 * config/vms-conf.h: new file, manually derived from conf.in.
4268 * config-gas.com: use it, and eliminate obsolete "host.h".

4272 * config/tc-ppc.c (ppc_current_block): New static variable.
4273 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to

4277 (ppc_es): Clear ppc_current_block.
4278 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
4279 from the csect of the enclosing block.
4281 * config/tc-mips.c (insns_since_cache_access): Remove.
4282 (append_insn): Remove setting of insns_since_cache_access, and
4283 special 4600 handling; it turns out not to be required.
4285 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4287 * config/tc-mips.c (md_shortopts): Remove E.
4288 (md_longopts): Add EB and EL.
4289 (md_parse_option): Handle -EB and -EL as separate options, rather
4290 than as a single -E option with an argument.

4294 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
4295 involving global symbols too.
4297 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4299 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
4301 * configure.in: Test for remove, not delete. Fix cross-assembler
4303 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
4306 * read.c (pseudo_set, case O_symbol): If
4307 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
4308 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
4309 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
4311 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
4313 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
4314 many others): new macros; values obtained from "DSTRECRDS.SDL".
4315 * config/obj-vms.h (various): use them.
4316 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
4317 representation (only enum bitfields can avoid being bitstrings).
4318 (bitfield_suffix, setup_basic_type): new routines.
4319 (VMS_typedef_parse): use them. Now recognize bitfields of all
4320 integral types, not just type `int'. Caveat: the representation
4321 used for bitfields still does not work for objects placed in
4322 registers, and gcc's optimizer sometimes puts small structs there.
4324 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
4326 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
4327 bit from const_flag.
4328 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
4329 (tc_frob_label): define this to call vms_check_for_special_label,
4330 and declare the latter.
4331 * config/obj-vms.c (vax_g_doubles): declare this file-scope
4333 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
4334 (vms_check_for_special_label): new routine (tc_frob_label).
4335 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
4336 and `gcc2_compiled.' labels; they won't reach here any more.
4337 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
4338 double', use `vax_g_doubles' flag to select type of double.
4339 (VMS_write_object_file) [traceback setup]: don't pass symbols
4340 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
4341 and TBT_Routine_End functions.

4345 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
4346 S_GET_VALUE() to avoid many repeated function calls.
4347 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
4348 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
4349 gets requested. [All the HACK_DEC_C_STARTUP code appears to
4350 be obsolete; gcc does it automatically for vms target. It's
4351 also misnamed, because it is for the "VAX C" run-time library,
4352 not the newer "DEC C" one which has much different startup code.]
4353 {various}: use `S_SET_xxx(symbol,new_value)' rather than
4354 `S_GET_xxx(symbol) = new_value'.
4356 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4358 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
4359 not &bfd_abs_section.
4361 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4363 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
4365 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
4367 * expr.c (expr): Don't reduce the difference of two symbols in the
4368 same frag if the symbols are not in normal sections.
4370 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
4371 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
4372 (obj_attach_unwind_info): Do not define. Not needed anymore.

4374 (struct hppa_fix_struct): Delete fx_unwind field and all references.
4375 (fix_new_hppa): Last arg is now a pointer to an int. Do not
4376 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
4377 fixups, store 32bits of unwind information in the fx_addnumber
4379 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
4380 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
4381 pointer to 32 bits of unwind info.
4382 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
4383 pointer to the dummy symbol; set the addend field to fx_addnumber.
4384 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
4385 rather than &bfd_XXX_section.
4387 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4389 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
4390 value by one; discard adjustments previously being made. From
4393 VMS- and Vax-related changes from Pat Rankin:
4394 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
4395 * vmsconf.sh: no longer have make-gas.com echo text about needing
4396 to modify the gcc-vms driver when intending to use with gcc 1.x.
4397 * as.c (parse_options): suppress 'v' from std_short_options and
4398 eliminate VMS-specific conditional initialization;
4399 [default case]: check for '-v' if md_parse_options doesn't recognize
4401 [default case, #if VMS]: check for filename argument when '-v' seen;
4403 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
4404 for O_big literal operands (double floats and long long ints);
4405 [VMS, md_shortopts]: add second colon after 'v';
4406 (md_parse_options) [VMS, case 'v']: check for argument, so
4407 caller can handle `-v' w/o arg.

4464 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
4465 to ensure that older versions of autoconf aren't used.
4466 * Makefile.in: Added @configure_input@ line.
4467 (configure): Deleted rule.
4469 Tue Sep 13 12:08:20 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4471 * config/obj-coff.c (fixup_segment): After handling the difference
4472 of two symbols from the same segment, set fx_subsy to NULL, to
4473 satisfy existing TC_COUNT_RELOC macros.

4526 symbols, force generation of the section symbol.
4527 (md_estimate_size_before_relax): If GOT_symbol exists, decide

4551 (s_mips_globl): New static function; needed for Irix 5 support.
4552 * ecoff.c (ecoff_build_symbols): If BSF_FUNCTION is set for an
4553 external symbol with no type, set the type to st_Proc rather than
4554 st_Global. Don't set the index of an external st_Proc or
4555 st_StaticProc symbol unless it is also a local symbol.
4557 * read.c (read_a_source_file): The second argument to as_where is
4558 unsigned int *, not int *.

4602 Update for autoconf beta 1.112:
4603 * aclocal.m4 (GAS_CHECK_DECL_NEEDED, GAS_WORKING_ASSERT): New
4605 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
4606 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
4607 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
4608 message to try to ease confusion about autoconf's
4609 "cross-compiling" message.
4610 * acconfig.h (NEED_DECLARATION_MALLOC, NEED_DECLARATION_FREE,
4611 NEED_DECLARATION_ERRNO): Renamed from NEED_*_DECLARATION.

5458 (control_regs): New pointer.
5459 (m68k_ip): Use control_regs instead of testing CPU every time.

6034 the type of symbol set symbols which happen to be in the absolute
6035 or undefined section.

6039 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
6040 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
6041 and -many (all architectures).
6043 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

6052 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
6054 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
6055 branch with an instruction that uses $at, in case the branch is
6057 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
6058 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
6059 to make it pcrel_offset.
6060 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
6061 reloc->address; another gruesome hack to get gas reloc handling to
6064 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6066 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
6069 (emit_insn): New function.
6070 (md_assemble): Call it.
6071 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
6073 (lituse_pending): New variable. Set by anything that generates a
6074 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
6075 tested by code that might want to emit a LITUSE reloc.
6076 (emit_unaligned_io): New function. Currently calls md_assemble,
6077 but it should eventually be converted to generate the insn itself
6078 and call emit_insn directly.
6079 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
6080 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
6081 emit_bis_r): Likewise.

6085 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
6086 unaligned memory access macros.
6087 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if

6090 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6092 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
6093 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
6094 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
6096 (mips_force_relocation): New function.
6097 (md_apply_fix): Set fixP->fx_done appropriately.
6098 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

6106 * config/tc-mips.c (enum mips_pic_level): New enum.
6107 (mips_pic): Change from int to enum mips_pic_level. Change all
6108 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
6109 (load_address): Handle EMBEDDED_PIC.
6110 (macro): Handle EMBEDDED_PIC in all PIC cases.
6111 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
6112 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
6113 -non_shared to use NO_PIC (this is how the Irix 5 assembler
6114 works). Do not permit -G with SVR4_PIC.
6115 (s_abicalls): Warn if -G was used, and force -G 0.
6116 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
6117 anything but a.out, not just for ELF. For ECOFF, don't generate a
6118 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
6120 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
6122 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6124 * config/tc-hppa.c (create_new_space): Use ints, not chars as
6125 parameters to avoid losing when compiling with HP CC.
6126 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
6128 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6130 * Makefile.in (config-stamp): If `defs' is defined, emit a
6131 preprocessor directive to create a macro named by this value into
6132 config.new; don't explicitly go for BFD_ASSEMBLER.
6133 * configure.in: Define `defs', not `BFDDEF'. Set it to
6134 MANY_SEGMENTS for any obj-coffbfd target.
6135 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
6136 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
6138 (LOCAL_LOADLIBES): Deleted.
6139 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
6140 * config/m88kcoff.mt (TDEFINES): Ditto.
6141 * config/ebmon29k.mt: Deleted.

6166 bfd_set_symtab is called.
6167 (dump_section_relocs): Note whether a symbol is a section symbol
6169 (adjust_reloc_syms): For now, always supply an absolute symbol for
6170 fixups without symbols but not yet `done'. Use section_symbol to
6171 get the symbol, instead of going directly for abs_symbol.
6172 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
6173 reloc is not a section symbol and is not in the symbol table.
6174 (set_symtab): New function, broken out from write_object_file.
6175 Counts symbol table instead of relying on an earlier count.
6176 (write_object_file): Call set_symtab, but do it after potentially
6177 invoking the *_frob_file macros. Don't bother counting symbols.
6178 Call symbol_remove, instead of expanding it in place. Moved the
6179 conditionalized `object_file_size' declaration down to
6180 conditionalized block where it's used. When using the absolute
6181 symbol for a fixup without a symbol, set sy_used_in_reloc.
6182 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
6183 the correct symbol for the absolute section.
6185 * subsegs.c (section_symbol): Use symbol_new instead of
6186 symbol_make, since we may want it to go into the symbol table.
6187 Make the new symbol have internal linkage. If
6188 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
6189 symbol with the newly created GAS symbol.
6190 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
6191 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

6196 (in_signed_range): New function.
6198 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
6199 (sparc_ip, label "immediate"): Reject constants for pcrel
6200 instructions only if the relocation type indicates a "call"
6201 instruction and the offset is within range of a "jmpl %g0". If
6202 it's not in range, use the absolute section symbol plus an offset.
6203 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
6205 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
6207 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
6210 * configure.in: Eliminated all targets using obj-coff but not
6211 defining BFD_ASSEMBLER; I think all such targets that are
6212 supported will be matched by real CPU-OS combinations earlier in
6214 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
6215 some comments about the dpx2 configuration, but left it disabled,
6216 since it couldn't be reached before.
6217 (target a29k-amd-ebmonold): Deleted.
6219 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

6227 the 'j' operand if there are no further alternatives for this
6230 * config/obj-coffbfd.c (adjust_stab_section): Initialize
6231 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
6232 is not SEG_UNKNOWN rather than checking whether it is >= 0.
6234 * config/tc-mips.c (mips_align): Take new argument, label, and use
6235 it instead of global insn_label.
6236 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
6237 call to mips_emit_delay and pass it to mips_align.
6239 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6241 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
6243 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
6244 argument to a .callinfo directive. Don't loop forever on errors.
6246 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
6247 use pre-defined registers as arguments.

6251 * write.c (write_object_file): Check both S_IS_LOCAL and
6252 S_IS_EXTERNAL when deciding whether to discard a symbol.
6254 * config-gas.com: Scan Makefile.in, not version.c, for current
6255 version number. Delete all versions of temp files when finished
6256 with them. Create config.h.
6258 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
6259 values to reduce number of lookups with S_GET_VALUE. Skip debug
6260 symbols to avoid "a really nasty bug". (From Holger Teutsch,
6261 holger@botbso.rhein-main.de.)
6262 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
6263 field. (Also from Holger Teutsch.) Watch for a would-be register
6264 mask that spans frags.
6266 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
6267 this_base, not line_base. (Patch from Andreas Arens,
6268 ari@obelix.av.rwth-aachen.de.)
6270 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
6271 look local if they're exported or undefined. Used to be done for
6274 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
6275 Get it from the looked-up symbol, instead of using the string from
6276 the input stream, which is no longer null-terminated.
6277 (LEX_PCT): New macro, defaults to 0.
6278 (lex_type): Use it for `%'.
6280 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
6281 (vip_op): Now static, and returns void. Callers changed. Added
6283 (vip): Ditto. Call as_fatal directly if a program bug is

6330 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
6331 0xffff for 'j' to be compatible with MIPS assembler. These

8403 * configure.in: Set bfd_gas for all sparc targets. Added facility
8404 for keeping or rejecting configurations still under development;
8405 default is to assume production environment, and reject configs
8406 still being worked on. Mark Elf configurations (except sparc and
8407 i386) as developmental. Deleted cases matching some generic names
8408 in favor of more specific names. (E.g., when we get Alpha

8426 for functions only used within tc-hppa.c, likewise for structures,
8427 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
8428 conditional code in a few small places.
8430 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group

8434 into a few places. Make all functions and variables which
8435 are only used within tc-hppa.c static. PARAMize all functions.
8436 Add comments to functions. Delete unused functions, variables,
8437 #defines, etc. Delete unused members within structures. Delete
8438 ldil;ble hacks -- it is believed they were installed to work
8439 around old gas bugs. Avoid using mixed case for local
8440 functions, variables, and structures. Fix formatting problems
8441 not found by GNU-indent. Add FIXME notices for things which
8442 should be worked on the near future. Delete lots of old
8443 useless (1.36 PA-SOM) code.

8460 * config/tc-hppa.c: Likewise.
8462 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
8463 of elf32_symbol_type.
8464 (pa_export_args): Likewise.

8472 a multiple of the section alignment rather than always a
8475 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
8476 bits are zero (eg they specify no relocations), then do not even
8477 bother adding their entries to thesymextn section.

8522 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
8524 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
8525 ELF, since the ELF object format does not have these type of
8526 relocations. Change the abort into as as_bad and return
8527 BFD_RELOC_NONE to silence compiler warnings.
8528 (md_assemble): Keep track of the instruction size. Allow white

10963 avoid some redefinition complaints on some systems.
10964 (const, volatile): Don't need these conditionally defined if we
10965 use CONST and VOLATILE from ansidecl.h.
10966 (seg_name): Use CONST, not const.

11014 dropping a space immediately following an identifier.

11090 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
11091 * config/tc-mips.c: Rearranged for ECOFF support. Added
11092 prototypes for all static functions. Moved existing minimal
11093 debugging format support info #ifndef OBJ_ECOFF blocks.
11094 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
11095 does not support a non sign extended high 16 bits reloc. Adjusted
11096 all callers accordingly.

11142 * make-gas.com: Find obstack.obj if it's not in the current
11144 * read.c (s_ignore): Don't declare is_end_of_line. It's
11145 redundant, and triggers a VMS gcc compiler bug.
11147 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
11148 current segment as an argument. (Ignored in all cases but VMS.)
11149 All callers and definitions changed.

11169 Call elf_xstabs for .stabs and .xstabs operators.
11171 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
11173 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
11176 * configure.in: mips-bsd configuration was missing format spec.
11179 * Makefile.in (Makefile): Depends on configure.in.
11181 * config/tc-mips.c (append_insn): Don't check for alignment of
11182 frag in memory; alignment of instructions in section is a separate

11202 * config/tc-sparc.c (s_xword): Now call big_cons, so large
11203 constants are accepted, but symbolic values are not. GCC will not
11204 generate the latter currently.
11206 * frags.c (frag_init): New function.

11480 (operand): Treat zero byte as end-of-operand.
11482 * configure.in (per-target): Look for with_bfd_assembler option.
11483 For now, only accept "no", until the merge is done.
11485 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
11486 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
11487 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
11488 * read.c: Finish conversion to S_* macros in the VMS only
11489 parts of the program. Add "const" modifier to hex_value.
11490 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
11492 * expr.c: Add "const" modifier to hex_value.
11493 * symbols.c: Finish conversion to S_* macros in the VMS only
11494 parts of the program. Add "const" modifier to
11495 md_[long,short]_jump_size. Remove declaration of const_flag
11496 (which will be declared in obj-vms.h).
11497 * write.c: Add "const" modifier to md_[long,short]_jump_size.
11498 Fix arguments to VMS_write_object_file.
11499 * config-gas.com: New file. Script for VMS systems to set up the
11500 configuration to build gas for VMS, and create config.status.
11501 * make-gas.com: Redone to work with new scheme.
11502 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
11504 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

11508 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
11509 types of malformed stabs. Change parsing algorithm so that we are
11510 more certain of having all of the information that we need on hand.
11511 * obj-vms.c (final_forward_reference): New function, used to help
11512 resolve the data types of as many struct elements as possible

11519 g++ compiler is incapable of doing this.
11520 * tc-vax.c: Add '1' option for backward compatibility with older GCC
11522 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

11530 SEG_DATA or SEG_E1 if needed.
11531 (s_lcomm): Likewise with bss_section.
11532 (s_fill): Use memset, not bzero.

11550 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
11551 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
11552 (segment_name) If BFD_ASSEMBLER, look up BFD section name;
11553 otherwise, use seg_name array.
11554 (seg_name): Declare only if not BFD_ASSEMBLER.
11555 (section_alignment): Declare only if not BFD_ASSEMBLER.
11556 (big_section, reg_section, pass1_section, diff_section,
11557 absent_section, text_section, data_section, bss_section): If
11558 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
11559 mapping to segT enum values.
11560 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
11561 if these are used or defined, if BFD_ASSEMBLER.
11562 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old

11570 declare with format attribute for -Wformat checking.
11572 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
11574 * app.c, config/tc-*.c: Don't include read.h, since it is already
11577 * These are based on patches from Minh Tran-le
11578 <mtranle@paris.intellicorp.com>.
11579 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
11580 obj_format coffbfd and gas_target i386coff for target.
11581 (i[34]86-*-isc*): New host (uses sysv).
11582 * config/i386aix.mt: Removed (no longer used).
11583 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
11584 (MINUS_G): Removed.
11585 (LDFLAGS): Added, defined as -shlib.
11586 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
11587 * config/te-sco386.h (LOCAL_LABEL): Don't define.
11588 (DOT_LABEL_PREFIX): Define.
11589 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
11590 name rather than L0\001.
11591 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
11593 * symbols.c, symbols.h (local_bss_counter): Removed.
11594 * write.c (write_object_file): bss no longer uses
11595 local_bss_counter. Pass correct data and bss size to
11596 VMS_write_object_file.
11597 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
11598 argument, rather than using local_bss_counter.

11601 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
11602 (size_section): Restored sanity check.
11603 (do_relocs_for): Base section address on s_paddr rather than
11604 computing it. Adjust a29k R_IHIHALF special case to account for
11605 section paddr (used to require paddr to be zero). If there are no
11606 reclos, set s_relptr to 0. Set relocation size in object_headers.
11607 (fill_section): Always set s_vaddr here, removing
11608 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
11609 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
11610 Set STYP_INFO for .comment.
11611 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
11612 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

11615 (do_linenos_for): Set lineno size in object_headers.
11616 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
11617 set s_vaddr here. If string_byte_count remains 4, set it back to
11618 0, and only write strings out if there are some. Call
11619 fill_section before do_relocs_for and do_linenos_for.
11620 (obj_coff_section): Handle optional quoted second argument giving
11621 section characteristics.
11622 (obj_coff_bss): Added to handle .bss.
11623 (obj_coff_ident): Added to handle .ident (puts string in .comment

11626 (fixup_mdeps): Change to segment. Call frag_wane after
11628 (fixup_segment): Explicitly check S_IS_COMMON before making 386
11629 adjustment (already happened only for common symbols, but this is

11642 * app.c (app_push): Use memcpy, not bcopy.
11643 (do_scrub_next_char): For \", return " not '.
11644 (symbol_chars): Now const.
11646 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
11647 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
11649 * config/obj-coff.h: Don't use #elif.
11651 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
11652 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
11654 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
11656 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

11674 * Changes to support SCO 3.2v4:
11675 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
11676 SEG_BSS, fill with NOP_OPCODE.
11677 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
11678 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
11679 using ZERO_BASED_SEGMENTS.
11680 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
11681 never set segment address for SEG_E2 (.bss) and don't write out
11682 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
11683 (obj_coff_endef): Don't merge labels or symbols awaiting forward
11684 definitions, and don't merge tags with non-tags. Check for .bf
11685 rather than just checking whether the second character is b and
11686 the third character is f.
11687 (obj_coff_val): gcc can generate values which we don't handle
11688 correctly; discard information for now, since it only affects the
11689 debugging information.
11690 (tag_find_or_name): Don't insert tags in the symbol table.
11691 (yank_symbols): Don't merge labels.
11692 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

11694 set segment address if ZERO_BASED_SEGMENTS.
11695 (obj_coff_section): Accept and ignore a trailing quoted string, as
11696 used in AT&T i386 syntax.

11842 z8000 documentation
11843 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
11846 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
11848 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
11850 * subsegs.h: add extern to segment_info declaration.
11852 * read.h: added extern declarations for comment_chars,
11853 line_comment_chars, and line_separator_chars.
11854 read.c, app.c: removed definitions of comment_chars,

11914 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
11915 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
11916 be used to set them all to zero as was done before.
11917 (fill_section): segment addresses now set in write_object_file.
11918 (fill_section): Don't set STYP_NOLOAD for .bss section.
11919 (fixup_segment): 386 uses strange common symbol format.
11920 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
11921 compatibility with SVR3.2 linker.
11922 * configure.in: i386-sysv and i386-sco use coffbfd.
11924 * app.c (do_scrub_next_char): discard whitespace after a label.
11926 Sat Oct 10 12:33:45 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
11928 * configure.in: differentiate between SunOS 4 and Solaris2 for Sun4

11933 fix i960+non-bfd coff bit rot.
11934 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
11935 support for C source listings. (obj_coff_endef): look in the right
11936 part of the symbol for the symbol name

11941 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
11943 * configure.in: recognize i386-*-bsd emulation.
11945 Thu Oct 1 23:05:12 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
11947 * configure.in: use the cpu-vendor-os triple for host and target
11949 Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11951 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
11952 * tc-z8k.c: lots of bug fixes
11954 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
11956 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
11957 #elif, since it is not supported by old compilers.
11958 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
11959 couple of expressions in tc-m68k.c.
11961 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11963 * read.c (cons): If NO_RELOC is defined, use it.

11967 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
11969 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
11970 local labels to start with a .) and set REGISTER_PREFIX to %.
11971 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
11973 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
11975 * messages.c: Comment changes.
11977 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
11979 * as.h: Test if __STDC__ is defined only, don't test its value.
11980 * messages.c: If __STDC__ is not defined, define NO_STDARG.
11982 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
11984 * listing.c (debugging_pseudo): Add stabs and stabn as things to
11987 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
11989 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
11990 sections starting from zero, rather than making them consecutive.
11991 This makes subsequent reloc calculations easier, esp if the object
11992 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
11993 allocate lcomm in .data rather than in .bss. It seems that some
11994 tools can't cope with a non-zero sized bss before linkage.
11996 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11998 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
11999 throughout. That enum no longer means what we thought it meant.
12001 * tc-m68k.c (md_assemble, md_parse_option): Handle new
12002 "-mno-688[58]1" options.

12022 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
12023 .word is < -32768 or > 32767. The -J flag causes the error to be
12024 ignored. This is to catch over-sized switches generated by gcc on
12025 systems which don't support the broken .word hack.
12026 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
12027 write.c (fixup_segment): check for signed .word overflow if
12028 WARN_SIGNED_OVERFLOW_WORD.

12106 * config/tc-m68k.c (init_table): Now const. Always include 68851
12107 data, so that "bc" is available to 68040 cache instructions.
12108 Added "tt0", "tt1", and 68ec030 variants.
12109 (md_assemble): Complain if 68000 (only) and 68881 are specified.

12134 so that we can assemble hand-written libgcc code.
12136 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
12138 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
12139 has already been formatted (but may still contain %-characters).
12140 (as_bad): Likewise.
12142 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
12144 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
12145 written with indirection on the last two operands, which can be
12146 either data or address registers. Added a new operand type 'r'
12147 which accepts either register type. Added '(' to notend stuff in
12148 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

12480 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
12481 copyrights to '92, changed some from Cygnus to FSF.
12483 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
12484 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
12485 copyrights to '92, changed some from Cygnus to FSF.
12487 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
12489 * expr.c: If an expression is single comma, then return with
12490 SEG_ABSENT rather than an error - since the sparc front end does
12491 really strange things with things like fbge,a
12493 * as.h: include bfd.h if using many sections
12494 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
12495 local labels didn't work.
12496 * listing.c (list_symbol_table): don't core dump when there's no
12498 * write.c, write.h: call fix_new with the right number of args on
12500 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
12503 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
12505 * app.c: MRI compatibility - allow single quote to start a string.
12506 * as.c: fix typo recently introduced.
12507 * as.h : Don't include aout/reloc.h - it's not right for COFF!
12508 * expr.c: Much rewriting, to accomodate MRI syntax for
12509 expressions. Also easier to read now.
12510 * listing.c: Put back defuns
12511 * read.c: modified to accept MRI syntax, put back listing pseudo
12512 ops so that an assembler built with NO_LISTING ignores list ops
12514 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
12515 machine is a SPARC or a 29K.
12516 * config/obj-aout.c: added s_sect pseudo op
12517 * config/obj-coffbfd.c: lints, set the filehdr flags right and
12518 fill in the timestamp.
12519 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
12520 anymore, define all the relocs which the tc-<x> bit will use so we
12521 can translate from them to the coff types.
12522 * config/tc-a29k.c: reloc_type isn't ane enum any more
12523 * config/tc-m68k.c: Added NO_RELOC definition.
12525 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
12527 * Makefile.in: put header files before C source for TAGS; remove
12528 references to non-existent syscalls.h.
12530 * read.c, write.c subsegs.c: back out the .bss changes.
12532 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
12534 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
12536 * a.out.h: removed.
12538 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
12540 * symbols.c (local_label_name): symbols now start with ^A.
12542 * read.c, subsegs.c, write.c obj-coff.c: added handling of
12543 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
12544 generate these sections. .align: will use NOP_OPCODE or 0
12545 for padding. This is just for being nice to the
12548 * expr.c (operand): changed to generate local label "\001L0"
12549 starting with a ^A so that it is recognized as a local label.
12551 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
12553 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
12554 i/o opcodes - inb, inw, outb and outw. string manipulation with
12555 att syntax - scmp, slod, smov, ssca, ssto.
12557 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
12558 to just after .file .
12560 In obj_crawl_symbol_chain() where it tries to put the external
12561 symbols apart, with the condition:
12562 (!S_IS_DEFINED(symbolP) &&
12563 !S_IS_DEBUG(symbolP) &&
12564 !SF_GET_STATICS(symbolP))
12565 it was moving too many symbols out. So I switch it back to the
12567 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
12569 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
12570 so that we don't use the F_RELFLG which make the linker complain
12571 that somebody has stripped the relocation info.
12573 Also, the AIX ld program require that the relocation table
12574 is sorted by r_vaddr like the standard ATT assembler does.
12576 [he also changed the sizeof(struct ...)'s into the coff
12577 style FOOSZ macros. I'm not sure this is right, but I can't
12578 remember why. xoxorich.]
12580 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
12582 * Makefile.in, configure.in, doc: use the doc. Build it, install
12585 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
12587 * read.c: white space and comments only.
12589 * configure.in: use the new atof-ns32.c for ns32k.
12591 * write.c: comment change only.
12593 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
12594 aren't yet integrated.
12596 * tc-i860.[hc]: blew off the dust. Something must still be done
12597 about conflicting relocation types.
12599 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
12602 * tc-i960.c, tc-sparc.c: white space and comments only.
12604 * tc-a29k.h: delete duplicate macro definition.
12606 * new file atof-ns32k.c copied from hack's last unreleased gas.
12608 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
12610 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
12613 * nearly everything. flush ChangeLog, package as gas-1.92.1.
12614 ChangeLog's prior to this are sketchy at best. I have logs.
12615 They just aren't ChangeLogs.
