4192 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
4193 default definitions matching what we were doing before.
4194 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
4195 always use the varargs form if not using stdarg. It's safe to
4196 always use vfprintf, because libiberty will provide it if the
4197 native system doesn't. Also, always make format be const.
4198 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

4214 deciding whether to record it.
4215 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
4216 false (if defined) as well as checking for reg_section.
4217 (listing_listing): Iterate fetching lines while line number is too
4218 low, and we haven't run off the end of the input file.
4220 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
4222 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
4224 * ecoff.c (ecoff_generate_asm_lineno): check if
4225 current_stabs_filename is NULL before strcmp.
4226 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
4229 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4231 * config/ho-*.h: Now-unused files deleted.
4233 * symbols.c (copy_symbol_attributes): New function. Copies BFD
4234 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
4235 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
4236 zero. Don't call obj_frob_forward_symbol.
4237 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
4238 X_add_number is zero.
4239 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
4241 * config/tc-i960.c: Lots of whitespace, comment reformatting,
4243 (strchr): Don't declare.

4245 md_estimate_size_before_relax, md_ri_to_chars,
4246 md_create_short_jump, md_create_long_jump.
4247 (brtab_emit): Use data_section, not SEG_DATA.
4249 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
4251 * config/vms-conf.h: new file, manually derived from conf.in.
4252 * config-gas.com: use it, and eliminate obsolete "host.h".

4256 * config/tc-ppc.c (ppc_current_block): New static variable.
4257 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to

4261 (ppc_es): Clear ppc_current_block.
4262 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
4263 from the csect of the enclosing block.
4265 * config/tc-mips.c (insns_since_cache_access): Remove.
4266 (append_insn): Remove setting of insns_since_cache_access, and
4267 special 4600 handling; it turns out not to be required.
4269 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4271 * config/tc-mips.c (md_shortopts): Remove E.
4272 (md_longopts): Add EB and EL.
4273 (md_parse_option): Handle -EB and -EL as separate options, rather
4274 than as a single -E option with an argument.

4278 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
4279 involving global symbols too.
4281 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4283 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
4285 * configure.in: Test for remove, not delete. Fix cross-assembler
4287 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
4290 * read.c (pseudo_set, case O_symbol): If
4291 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
4292 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
4293 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
4295 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
4297 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
4298 many others): new macros; values obtained from "DSTRECRDS.SDL".
4299 * config/obj-vms.h (various): use them.
4300 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
4301 representation (only enum bitfields can avoid being bitstrings).
4302 (bitfield_suffix, setup_basic_type): new routines.
4303 (VMS_typedef_parse): use them. Now recognize bitfields of all
4304 integral types, not just type `int'. Caveat: the representation
4305 used for bitfields still does not work for objects placed in
4306 registers, and gcc's optimizer sometimes puts small structs there.
4308 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
4310 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
4311 bit from const_flag.
4312 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
4313 (tc_frob_label): define this to call vms_check_for_special_label,
4314 and declare the latter.
4315 * config/obj-vms.c (vax_g_doubles): declare this file-scope
4317 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
4318 (vms_check_for_special_label): new routine (tc_frob_label).
4319 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
4320 and `gcc2_compiled.' labels; they won't reach here any more.
4321 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
4322 double', use `vax_g_doubles' flag to select type of double.
4323 (VMS_write_object_file) [traceback setup]: don't pass symbols
4324 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
4325 and TBT_Routine_End functions.

4329 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
4330 S_GET_VALUE() to avoid many repeated function calls.
4331 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
4332 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
4333 gets requested. [All the HACK_DEC_C_STARTUP code appears to
4334 be obsolete; gcc does it automatically for vms target. It's
4335 also misnamed, because it is for the "VAX C" run-time library,
4336 not the newer "DEC C" one which has much different startup code.]
4337 {various}: use `S_SET_xxx(symbol,new_value)' rather than
4338 `S_GET_xxx(symbol) = new_value'.
4340 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4342 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
4343 not &bfd_abs_section.
4345 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4347 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
4349 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
4351 * expr.c (expr): Don't reduce the difference of two symbols in the
4352 same frag if the symbols are not in normal sections.
4354 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
4355 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
4356 (obj_attach_unwind_info): Do not define. Not needed anymore.

4358 (struct hppa_fix_struct): Delete fx_unwind field and all references.
4359 (fix_new_hppa): Last arg is now a pointer to an int. Do not
4360 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
4361 fixups, store 32bits of unwind information in the fx_addnumber
4363 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
4364 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
4365 pointer to 32 bits of unwind info.
4366 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
4367 pointer to the dummy symbol; set the addend field to fx_addnumber.
4368 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
4369 rather than &bfd_XXX_section.
4371 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4373 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
4374 value by one; discard adjustments previously being made. From
4377 VMS- and Vax-related changes from Pat Rankin:
4378 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
4379 * vmsconf.sh: no longer have make-gas.com echo text about needing
4380 to modify the gcc-vms driver when intending to use with gcc 1.x.
4381 * as.c (parse_options): suppress 'v' from std_short_options and
4382 eliminate VMS-specific conditional initialization;
4383 [default case]: check for '-v' if md_parse_options doesn't recognize
4385 [default case, #if VMS]: check for filename argument when '-v' seen;
4387 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
4388 for O_big literal operands (double floats and long long ints);
4389 [VMS, md_shortopts]: add second colon after 'v';
4390 (md_parse_options) [VMS, case 'v']: check for argument, so
4391 caller can handle `-v' w/o arg.

4447 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
4448 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
4449 to ensure that older versions of autoconf aren't used.
4450 * Makefile.in: Added @configure_input@ line.
4451 (configure): Deleted rule.

4510 symbols, force generation of the section symbol.
4511 (md_estimate_size_before_relax): If GOT_symbol exists, decide

4535 (s_mips_globl): New static function; needed for Irix 5 support.
4536 * ecoff.c (ecoff_build_symbols): If BSF_FUNCTION is set for an
4537 external symbol with no type, set the type to st_Proc rather than
4538 st_Global. Don't set the index of an external st_Proc or
4539 st_StaticProc symbol unless it is also a local symbol.
4541 * read.c (read_a_source_file): The second argument to as_where is

4586 Update for autoconf beta 1.112:
4587 * aclocal.m4 (GAS_CHECK_DECL_NEEDED, GAS_WORKING_ASSERT): New
4589 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
4590 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
4591 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
4592 message to try to ease confusion about autoconf's
4593 "cross-compiling" message.
4594 * acconfig.h (NEED_DECLARATION_MALLOC, NEED_DECLARATION_FREE,
4595 NEED_DECLARATION_ERRNO): Renamed from NEED_*_DECLARATION.

5442 (control_regs): New pointer.
5443 (m68k_ip): Use control_regs instead of testing CPU every time.

6035 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
6036 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
6038 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
6039 branch with an instruction that uses $at, in case the branch is
6041 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
6042 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
6043 to make it pcrel_offset.
6044 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
6045 reloc->address; another gruesome hack to get gas reloc handling to
6048 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6050 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
6053 (emit_insn): New function.
6054 (md_assemble): Call it.
6055 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
6057 (lituse_pending): New variable. Set by anything that generates a
6058 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
6059 tested by code that might want to emit a LITUSE reloc.
6060 (emit_unaligned_io): New function. Currently calls md_assemble,
6061 but it should eventually be converted to generate the insn itself
6062 and call emit_insn directly.
6063 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
6064 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
6065 emit_bis_r): Likewise.

6069 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
6070 unaligned memory access macros.
6071 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
6072 the value can't be resolved.
6074 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6076 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
6077 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
6078 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
6080 (mips_force_relocation): New function.
6081 (md_apply_fix): Set fixP->fx_done appropriately.
6082 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

6090 * config/tc-mips.c (enum mips_pic_level): New enum.
6091 (mips_pic): Change from int to enum mips_pic_level. Change all
6092 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
6093 (load_address): Handle EMBEDDED_PIC.
6094 (macro): Handle EMBEDDED_PIC in all PIC cases.
6095 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
6096 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
6097 -non_shared to use NO_PIC (this is how the Irix 5 assembler
6098 works). Do not permit -G with SVR4_PIC.
6099 (s_abicalls): Warn if -G was used, and force -G 0.
6100 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
6101 anything but a.out, not just for ELF. For ECOFF, don't generate a
6102 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
6104 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
6106 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6108 * config/tc-hppa.c (create_new_space): Use ints, not chars as
6109 parameters to avoid losing when compiling with HP CC.
6110 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
6112 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6114 * Makefile.in (config-stamp): If `defs' is defined, emit a
6115 preprocessor directive to create a macro named by this value into
6116 config.new; don't explicitly go for BFD_ASSEMBLER.
6117 * configure.in: Define `defs', not `BFDDEF'. Set it to
6118 MANY_SEGMENTS for any obj-coffbfd target.
6119 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
6120 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
6122 (LOCAL_LOADLIBES): Deleted.
6123 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
6124 * config/m88kcoff.mt (TDEFINES): Ditto.

6150 bfd_set_symtab is called.
6151 (dump_section_relocs): Note whether a symbol is a section symbol
6153 (adjust_reloc_syms): For now, always supply an absolute symbol for
6154 fixups without symbols but not yet `done'. Use section_symbol to
6155 get the symbol, instead of going directly for abs_symbol.
6156 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
6157 reloc is not a section symbol and is not in the symbol table.
6158 (set_symtab): New function, broken out from write_object_file.
6159 Counts symbol table instead of relying on an earlier count.
6160 (write_object_file): Call set_symtab, but do it after potentially
6161 invoking the *_frob_file macros. Don't bother counting symbols.
6162 Call symbol_remove, instead of expanding it in place. Moved the
6163 conditionalized `object_file_size' declaration down to
6164 conditionalized block where it's used. When using the absolute
6165 symbol for a fixup without a symbol, set sy_used_in_reloc.
6166 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
6167 the correct symbol for the absolute section.
6169 * subsegs.c (section_symbol): Use symbol_new instead of
6170 symbol_make, since we may want it to go into the symbol table.
6171 Make the new symbol have internal linkage. If
6172 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
6173 symbol with the newly created GAS symbol.
6174 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
6175 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

6182 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
6183 (sparc_ip, label "immediate"): Reject constants for pcrel
6184 instructions only if the relocation type indicates a "call"
6185 instruction and the offset is within range of a "jmpl %g0". If
6186 it's not in range, use the absolute section symbol plus an offset.
6187 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
6189 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
6191 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
6194 * configure.in: Eliminated all targets using obj-coff but not
6195 defining BFD_ASSEMBLER; I think all such targets that are
6196 supported will be matched by real CPU-OS combinations earlier in
6198 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
6199 some comments about the dpx2 configuration, but left it disabled,
6200 since it couldn't be reached before.
6201 (target a29k-amd-ebmonold): Deleted.
6203 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

6211 the 'j' operand if there are no further alternatives for this
6214 * config/obj-coffbfd.c (adjust_stab_section): Initialize
6215 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
6216 is not SEG_UNKNOWN rather than checking whether it is >= 0.
6218 * config/tc-mips.c (mips_align): Take new argument, label, and use
6219 it instead of global insn_label.
6220 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
6221 call to mips_emit_delay and pass it to mips_align.
6223 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6225 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.

6236 S_IS_EXTERNAL when deciding whether to discard a symbol.
6238 * config-gas.com: Scan Makefile.in, not version.c, for current
6239 version number. Delete all versions of temp files when finished
6240 with them. Create config.h.
6242 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
6243 values to reduce number of lookups with S_GET_VALUE. Skip debug
6244 symbols to avoid "a really nasty bug". (From Holger Teutsch,
6245 holger@botbso.rhein-main.de.)
6246 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
6247 field. (Also from Holger Teutsch.) Watch for a would-be register
6248 mask that spans frags.
6250 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
6251 this_base, not line_base. (Patch from Andreas Arens,

6254 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
6255 look local if they're exported or undefined. Used to be done for
6258 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
6259 Get it from the looked-up symbol, instead of using the string from
6260 the input stream, which is no longer null-terminated.
6261 (LEX_PCT): New macro, defaults to 0.
6262 (lex_type): Use it for `%'.
6264 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

6314 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
6315 0xffff for 'j' to be compatible with MIPS assembler. These

8385 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
8387 * configure.in: Set bfd_gas for all sparc targets. Added facility
8388 for keeping or rejecting configurations still under development;
8389 default is to assume production environment, and reject configs
8390 still being worked on. Mark Elf configurations (except sparc and
8391 i386) as developmental. Deleted cases matching some generic names
8392 in favor of more specific names. (E.g., when we get Alpha

8409 through inclusion of tc-hppa.h. Delete all forward declarations
8410 for functions only used within tc-hppa.c, likewise for structures,
8411 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
8412 conditional code in a few small places.
8414 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
8415 structures, global variables, forward declarations together.

8417 conditional code -- try to group conditional code together
8418 into a few places. Make all functions and variables which
8419 are only used within tc-hppa.c static. PARAMize all functions.
8420 Add comments to functions. Delete unused functions, variables,
8421 #defines, etc. Delete unused members within structures. Delete
8422 ldil;ble hacks -- it is believed they were installed to work
8423 around old gas bugs. Avoid using mixed case for local
8424 functions, variables, and structures. Fix formatting problems
8425 not found by GNU-indent. Add FIXME notices for things which
8426 should be worked on the near future. Delete lots of old
8427 useless (1.36 PA-SOM) code.

8444 * config/tc-hppa.c: Likewise.
8446 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
8447 of elf32_symbol_type.
8448 (pa_export_args): Likewise.
8449 (elf_hppa_final_processing): Likewise.

8456 a multiple of the section alignment rather than always a
8459 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
8460 bits are zero (eg they specify no relocations), then do not even
8461 bother adding their entries to thesymextn section.

8506 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
8508 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
8509 ELF, since the ELF object format does not have these type of
8510 relocations. Change the abort into as as_bad and return
8511 BFD_RELOC_NONE to silence compiler warnings.
8512 (md_assemble): Keep track of the instruction size. Allow white

10895 dependencies are read, not when they are used).
10897 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
10898 a29k .bss section; the mondfe program doesn't like it.

10919 source directory, if that's not the current directory.
10921 * configure.in (per-host): Accept MIPS host with BSD version

10947 avoid some redefinition complaints on some systems.
10948 (const, volatile): Don't need these conditionally defined if we
10949 use CONST and VOLATILE from ansidecl.h.
10950 (seg_name): Use CONST, not const.
10952 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
10954 * config/tc-mips.c: Reindented to GNU standards.

10958 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

10998 dropping a space immediately following an identifier.

11012 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
11013 by the section vma.
11015 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is

11076 prototypes for all static functions. Moved existing minimal
11077 debugging format support info #ifndef OBJ_ECOFF blocks.

11123 Wed Mar 3 10:41:46 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
11125 Patches from Eric Youngdale:
11126 * make-gas.com: Find obstack.obj if it's not in the current
11128 * read.c (s_ignore): Don't declare is_end_of_line. It's
11129 redundant, and triggers a VMS gcc compiler bug.
11131 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
11132 current segment as an argument. (Ignored in all cases but VMS.)
11133 All callers and definitions changed.

11140 Tue Mar 2 08:53:34 1993 Ken Raeburn (raeburn@cygnus.com)
11142 * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,
11143 so "~0x80" won't be rejected.
11145 * config/obj-elf.c: No longer include elf/reloc.h.
11146 (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
11147 (obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out
11149 (obj_elf_xstab): New routine.
11150 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
11151 argument to s_ignore. Put "#if 0" around unused code.
11152 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
11153 Call elf_xstabs for .stabs and .xstabs operators.
11155 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
11157 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
11160 * configure.in: mips-bsd configuration was missing format spec.
11163 * Makefile.in (Makefile): Depends on configure.in.
11165 * config/tc-mips.c (append_insn): Don't check for alignment of
11166 frag in memory; alignment of instructions in section is a separate
11169 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
11172 * listing.h: Always provide function declarations, not macros, so
11175 Tue Mar 2 00:50:43 1993 John Gilmore (gnu@cygnus.com)

11186 * config/tc-sparc.c (s_xword): Now call big_cons, so large
11187 constants are accepted, but symbolic values are not. GCC will not
11188 generate the latter currently.
11190 * frags.c (frag_init): New function.
11191 (zero_address_frag, bss_address_frag): Now initialized at run

11236 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
11237 (fixup_segment): Make sure common-section symbols get treated the
11238 same as undefined symbols.

11244 * tc.h (md_operand, md_convert_frag, tc_headers_hook,
11245 md_section_align, md_undefined_symbol): Don't provide prototypes
11246 if these are defined as macros.
11247 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and

11269 new section/subsection.
11271 * read.c: Don't include ctype.h.
11272 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
11273 for now; should be machine-dependent.
11275 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format

11466 * configure.in (per-target): Look for with_bfd_assembler option.
11467 For now, only accept "no", until the merge is done.
11469 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
11470 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
11471 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
11472 * read.c: Finish conversion to S_* macros in the VMS only
11473 parts of the program. Add "const" modifier to hex_value.

11476 * expr.c: Add "const" modifier to hex_value.
11477 * symbols.c: Finish conversion to S_* macros in the VMS only
11478 parts of the program. Add "const" modifier to

11481 * write.c: Add "const" modifier to md_[long,short]_jump_size.
11482 Fix arguments to VMS_write_object_file.
11483 * config-gas.com: New file. Script for VMS systems to set up the
11484 configuration to build gas for VMS, and create config.status.
11485 * make-gas.com: Redone to work with new scheme.
11486 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
11488 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

11492 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
11493 types of malformed stabs. Change parsing algorithm so that we are
11494 more certain of having all of the information that we need on hand.
11495 * obj-vms.c (final_forward_reference): New function, used to help
11496 resolve the data types of as many struct elements as possible

11503 g++ compiler is incapable of doing this.
11504 * tc-vax.c: Add '1' option for backward compatibility with older GCC
11506 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

11514 SEG_DATA or SEG_E1 if needed.
11515 (s_lcomm): Likewise with bss_section.
11516 (s_fill): Use memset, not bzero.

11545 if these are used or defined, if BFD_ASSEMBLER.
11546 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
11547 subseg_new split into two functions.

11553 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
11554 declare with format attribute for -Wformat checking.
11556 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
11558 * app.c, config/tc-*.c: Don't include read.h, since it is already
11561 * These are based on patches from Minh Tran-le
11562 <mtranle@paris.intellicorp.com>.
11563 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
11564 obj_format coffbfd and gas_target i386coff for target.
11565 (i[34]86-*-isc*): New host (uses sysv).
11566 * config/i386aix.mt: Removed (no longer used).
11567 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
11568 (MINUS_G): Removed.
11569 (LDFLAGS): Added, defined as -shlib.
11570 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
11571 * config/te-sco386.h (LOCAL_LABEL): Don't define.
11572 (DOT_LABEL_PREFIX): Define.
11573 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
11574 name rather than L0\001.
11575 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
11577 * symbols.c, symbols.h (local_bss_counter): Removed.
11578 * write.c (write_object_file): bss no longer uses
11579 local_bss_counter. Pass correct data and bss size to
11580 VMS_write_object_file.
11581 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
11582 argument, rather than using local_bss_counter.

11584 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
11585 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
11586 (size_section): Restored sanity check.
11587 (do_relocs_for): Base section address on s_paddr rather than
11588 computing it. Adjust a29k R_IHIHALF special case to account for
11589 section paddr (used to require paddr to be zero). If there are no
11590 reclos, set s_relptr to 0. Set relocation size in object_headers.
11591 (fill_section): Always set s_vaddr here, removing
11592 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
11593 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
11594 Set STYP_INFO for .comment.
11595 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
11596 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

11598 H_{SET,GET}_* macros.
11599 (do_linenos_for): Set lineno size in object_headers.
11600 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
11601 set s_vaddr here. If string_byte_count remains 4, set it back to
11602 0, and only write strings out if there are some. Call
11603 fill_section before do_relocs_for and do_linenos_for.
11604 (obj_coff_section): Handle optional quoted second argument giving
11605 section characteristics.
11606 (obj_coff_bss): Added to handle .bss.
11607 (obj_coff_ident): Added to handle .ident (puts string in .comment
11609 (obj_coff_lcomm): Put common symbols in .bss, not .data.
11610 (fixup_mdeps): Change to segment. Call frag_wane after
11612 (fixup_segment): Explicitly check S_IS_COMMON before making 386
11613 adjustment (already happened only for common symbols, but this is
11615 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
11616 * config/tc-i386.c (s_bss): Don't use if I386COFF.

11621 (LOCAL_LABEL): Removed definition.
11622 (DOT_LABEL_PREFIX): Defined.
11624 Mon Dec 28 10:32:05 1992 Ken Raeburn (raeburn@cygnus.com)
11626 * app.c (app_push): Use memcpy, not bcopy.
11627 (do_scrub_next_char): For \", return " not '.
11628 (symbol_chars): Now const.
11630 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
11631 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
11633 * config/obj-coff.h: Don't use #elif.
11635 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
11636 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
11638 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
11640 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

11654 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
11656 * listing.c: Call xmalloc, not malloc; don't declare malloc.
11658 * Changes to support SCO 3.2v4:
11659 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
11660 SEG_BSS, fill with NOP_OPCODE.
11661 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
11662 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
11663 using ZERO_BASED_SEGMENTS.
11664 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
11665 never set segment address for SEG_E2 (.bss) and don't write out
11666 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
11667 (obj_coff_endef): Don't merge labels or symbols awaiting forward
11668 definitions, and don't merge tags with non-tags. Check for .bf
11669 rather than just checking whether the second character is b and
11670 the third character is f.
11671 (obj_coff_val): gcc can generate values which we don't handle
11672 correctly; discard information for now, since it only affects the
11673 debugging information.
11674 (tag_find_or_name): Don't insert tags in the symbol table.
11675 (yank_symbols): Don't merge labels.
11676 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

11678 set segment address if ZERO_BASED_SEGMENTS.
11679 (obj_coff_section): Accept and ignore a trailing quoted string, as
11680 used in AT&T i386 syntax.

11682 relative addends by the segment vaddr.
11683 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
11684 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

11696 power-of-two alignment for .align.
11698 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
11699 and leave everything else alone.

11731 options. Updated options documentation for m68k. Some minor
11732 wording/punctuation changes.

11796 don't initialize it with NULL.
11798 * config/ho-vax.h (M_VAX): Deleted; was unused.
11800 * README-vms, config/ho-vms.h, config/obj-vms.c, config/obj-vms.h:
11801 New files imported from FSF version, contributed by Eric Youngdale.
11802 * README-vms-dbg, config/vms: Deleted.

11826 z8000 documentation
11827 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
11830 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
11832 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
11834 * subsegs.h: add extern to segment_info declaration.
11836 * read.h: added extern declarations for comment_chars,
11837 line_comment_chars, and line_separator_chars.
11838 read.c, app.c: removed definitions of comment_chars,
11839 line_comment_chars, and line_separator_chars.
11841 * tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
11842 still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
11844 (insert_reg): put REGISTER_PREFIX before register names before
11845 putting them in the symbol table.
11846 * tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not

11856 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11858 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
11859 constant will not fit in an immediate field.
11860 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
11862 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
11864 * obj-coff.c (callj_table): Delete global variable.
11865 (obj_emit_relocations): Define it locally here, and only if
11866 TC_I960 is defined.
11868 * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.

11895 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
11897 * Support for i386-sysv.
11898 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
11899 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
11900 be used to set them all to zero as was done before.
11901 (fill_section): segment addresses now set in write_object_file.
11902 (fill_section): Don't set STYP_NOLOAD for .bss section.
11903 (fixup_segment): 386 uses strange common symbol format.
11904 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
11905 compatibility with SVR3.2 linker.
11906 * configure.in: i386-sysv and i386-sco use coffbfd.
11908 * app.c (do_scrub_next_char): discard whitespace after a label.
11910 Sat Oct 10 12:33:45 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

11917 fix i960+non-bfd coff bit rot.
11918 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
11919 support for C source listings. (obj_coff_endef): look in the right
11920 part of the symbol for the symbol name
11922 * tc-m68k.c (get_num): make it work for all segments, not just the
11925 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
11927 * configure.in: recognize i386-*-bsd emulation.
11929 Thu Oct 1 23:05:12 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
11931 * configure.in: use the cpu-vendor-os triple for host and target
11933 Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11935 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
11936 * tc-z8k.c: lots of bug fixes
11938 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
11940 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
11941 #elif, since it is not supported by old compilers.
11942 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
11943 couple of expressions in tc-m68k.c.
11945 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11947 * read.c (cons): If NO_RELOC is defined, use it.
11949 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
11951 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
11953 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
11954 local labels to start with a .) and set REGISTER_PREFIX to %.
11955 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
11957 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
11959 * messages.c: Comment changes.
11961 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
11963 * as.h: Test if __STDC__ is defined only, don't test its value.
11964 * messages.c: If __STDC__ is not defined, define NO_STDARG.
11966 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
11968 * listing.c (debugging_pseudo): Add stabs and stabn as things to
11971 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
11973 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
11974 sections starting from zero, rather than making them consecutive.
11975 This makes subsequent reloc calculations easier, esp if the object
11976 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
11977 allocate lcomm in .data rather than in .bss. It seems that some
11978 tools can't cope with a non-zero sized bss before linkage.
11980 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11982 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
11983 throughout. That enum no longer means what we thought it meant.
11985 * tc-m68k.c (md_assemble, md_parse_option): Handle new
11986 "-mno-688[58]1" options.
11988 * tc-m68k.c: Added CPU32 support.
11990 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11992 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
11994 Tue Sep 15 17:25:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11996 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
11997 Change LIBDEPS dependence to LIBS.
11999 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
12001 * Makefile.in (install): if $(tooldir) exists, install as in
12004 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
12006 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
12007 .word is < -32768 or > 32767. The -J flag causes the error to be
12008 ignored. This is to catch over-sized switches generated by gcc on
12009 systems which don't support the broken .word hack.
12010 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.

12494 * listing.c: Put back defuns
12495 * read.c: modified to accept MRI syntax, put back listing pseudo
12496 ops so that an assembler built with NO_LISTING ignores list ops
12498 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
12499 machine is a SPARC or a 29K.
12500 * config/obj-aout.c: added s_sect pseudo op
12501 * config/obj-coffbfd.c: lints, set the filehdr flags right and
12502 fill in the timestamp.
12503 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
12504 anymore, define all the relocs which the tc-<x> bit will use so we
12505 can translate from them to the coff types.
12506 * config/tc-a29k.c: reloc_type isn't ane enum any more
12507 * config/tc-m68k.c: Added NO_RELOC definition.
12509 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
12511 * Makefile.in: put header files before C source for TAGS; remove
12512 references to non-existent syscalls.h.
12514 * read.c, write.c subsegs.c: back out the .bss changes.
12516 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
12518 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
12520 * a.out.h: removed.
12522 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
12524 * symbols.c (local_label_name): symbols now start with ^A.
12526 * read.c, subsegs.c, write.c obj-coff.c: added handling of
12527 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
12528 generate these sections. .align: will use NOP_OPCODE or 0
12529 for padding. This is just for being nice to the
12532 * expr.c (operand): changed to generate local label "\001L0"
12533 starting with a ^A so that it is recognized as a local label.
12535 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
12537 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
12538 i/o opcodes - inb, inw, outb and outw. string manipulation with
12539 att syntax - scmp, slod, smov, ssca, ssto.
12541 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
12542 to just after .file .
12544 In obj_crawl_symbol_chain() where it tries to put the external
12545 symbols apart, with the condition:
12546 (!S_IS_DEFINED(symbolP) &&
12547 !S_IS_DEBUG(symbolP) &&
12548 !SF_GET_STATICS(symbolP))
12549 it was moving too many symbols out. So I switch it back to the
12551 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
12553 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
12554 so that we don't use the F_RELFLG which make the linker complain
12555 that somebody has stripped the relocation info.
12557 Also, the AIX ld program require that the relocation table
12558 is sorted by r_vaddr like the standard ATT assembler does.
12560 [he also changed the sizeof(struct ...)'s into the coff
12561 style FOOSZ macros. I'm not sure this is right, but I can't
12562 remember why. xoxorich.]
12564 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
12566 * Makefile.in, configure.in, doc: use the doc. Build it, install
12569 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
12571 * read.c: white space and comments only.
12573 * configure.in: use the new atof-ns32.c for ns32k.
12575 * write.c: comment change only.
12577 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
12578 aren't yet integrated.
12580 * tc-i860.[hc]: blew off the dust. Something must still be done
12581 about conflicting relocation types.
12583 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
12586 * tc-i960.c, tc-sparc.c: white space and comments only.
12588 * tc-a29k.h: delete duplicate macro definition.
12590 * new file atof-ns32k.c copied from hack's last unreleased gas.
12592 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
12594 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
12597 * nearly everything. flush ChangeLog, package as gas-1.92.1.
12598 ChangeLog's prior to this are sketchy at best. I have logs.
12599 They just aren't ChangeLogs.
