4195 * expr.h (make_expr_symbol): Move declaration here.
4196 * write.c (fix_new_exp): Handle O_add by creating an
4197 expression-valued symbol, and calling fix_new_exp recursively.
4198 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
4199 undefined symbol and a constant, fold the constant into the fixup,
4200 and refer to the undefined symbol directly. Then process the
4201 fixup again from scratch.
4202 (write_object_file): Before calling adjust_reloc_syms, make a pass
4203 through the symbol list trying to resolve values.
4205 * write.c (print_fixup): New routine, for debugging.
4206 (write_relocs): Call bfd_install_relocation. Deleted various
4207 hacks for working around problems with bfd_perform_relocation.
4209 * Makefile.in (VERSION): Update to 2.4.90.
4211 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4213 * Makefile.in (gasp.o): Depends upon config.h.
4215 * config/tc-mips.c: Include subsegs.h.
4216 (md_apply_fix): If an unconditional b or bal overflows, and we are
4217 not assembling PIC code, replace it with a j or jal.
4219 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
4220 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
4222 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4224 * write.c (write_relocs): Add file name and line number to
4225 as_fatal calls. Handle bfd_reloc_overflow case specifically when
4226 RELOC_EXPANSION_POSSIBLE.
4228 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4230 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
4231 here. Use them for deciding which PRINTF*LIKE macro definitions
4233 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
4234 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
4235 default definitions matching what we were doing before.
4236 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
4237 always use the varargs form if not using stdarg. It's safe to
4238 always use vfprintf, because libiberty will provide it if the
4239 native system doesn't. Also, always make format be const.
4240 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
4242 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

4255 (listing_newline): Check filename as well as line number when
4256 deciding whether to record it.
4257 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
4258 false (if defined) as well as checking for reg_section.
4259 (listing_listing): Iterate fetching lines while line number is too
4260 low, and we haven't run off the end of the input file.
4262 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
4264 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
4266 * ecoff.c (ecoff_generate_asm_lineno): check if
4267 current_stabs_filename is NULL before strcmp.
4268 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
4271 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
4273 * config/ho-*.h: Now-unused files deleted.
4275 * symbols.c (copy_symbol_attributes): New function. Copies BFD
4276 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
4277 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
4278 zero. Don't call obj_frob_forward_symbol.
4279 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
4280 X_add_number is zero.
4281 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
4283 * config/tc-i960.c: Lots of whitespace, comment reformatting,
4285 (strchr): Don't declare.
4286 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
4287 md_estimate_size_before_relax, md_ri_to_chars,
4288 md_create_short_jump, md_create_long_jump.
4289 (brtab_emit): Use data_section, not SEG_DATA.
4291 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
4293 * config/vms-conf.h: new file, manually derived from conf.in.
4294 * config-gas.com: use it, and eliminate obsolete "host.h".
4296 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4298 * config/tc-ppc.c (ppc_current_block): New static variable.
4299 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
4300 ppc_current_block. Don't move around any stab symbol, just those

4303 (ppc_es): Clear ppc_current_block.
4304 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
4305 from the csect of the enclosing block.
4307 * config/tc-mips.c (insns_since_cache_access): Remove.
4308 (append_insn): Remove setting of insns_since_cache_access, and
4309 special 4600 handling; it turns out not to be required.
4311 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4313 * config/tc-mips.c (md_shortopts): Remove E.
4314 (md_longopts): Add EB and EL.
4315 (md_parse_option): Handle -EB and -EL as separate options, rather
4316 than as a single -E option with an argument.
4318 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
4320 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
4321 involving global symbols too.
4323 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4325 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
4327 * configure.in: Test for remove, not delete. Fix cross-assembler
4329 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
4332 * read.c (pseudo_set, case O_symbol): If
4333 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
4334 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
4335 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
4337 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
4339 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
4340 many others): new macros; values obtained from "DSTRECRDS.SDL".
4341 * config/obj-vms.h (various): use them.
4342 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
4343 representation (only enum bitfields can avoid being bitstrings).
4344 (bitfield_suffix, setup_basic_type): new routines.
4345 (VMS_typedef_parse): use them. Now recognize bitfields of all
4346 integral types, not just type `int'. Caveat: the representation
4347 used for bitfields still does not work for objects placed in
4348 registers, and gcc's optimizer sometimes puts small structs there.
4350 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
4352 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
4353 bit from const_flag.
4354 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
4355 (tc_frob_label): define this to call vms_check_for_special_label,
4356 and declare the latter.
4357 * config/obj-vms.c (vax_g_doubles): declare this file-scope
4359 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
4360 (vms_check_for_special_label): new routine (tc_frob_label).
4361 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
4362 and `gcc2_compiled.' labels; they won't reach here any more.
4363 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
4364 double', use `vax_g_doubles' flag to select type of double.
4365 (VMS_write_object_file) [traceback setup]: don't pass symbols
4366 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
4367 and TBT_Routine_End functions.

4371 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
4372 S_GET_VALUE() to avoid many repeated function calls.
4373 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
4374 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
4375 gets requested. [All the HACK_DEC_C_STARTUP code appears to
4376 be obsolete; gcc does it automatically for vms target. It's
4377 also misnamed, because it is for the "VAX C" run-time library,
4378 not the newer "DEC C" one which has much different startup code.]
4379 {various}: use `S_SET_xxx(symbol,new_value)' rather than
4380 `S_GET_xxx(symbol) = new_value'.
4382 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4384 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
4385 not &bfd_abs_section.
4387 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4389 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
4391 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
4393 * expr.c (expr): Don't reduce the difference of two symbols in the
4394 same frag if the symbols are not in normal sections.
4396 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
4397 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
4398 (obj_attach_unwind_info): Do not define. Not needed anymore.
4399 * config/tc-hppa.c: Delete whitespace at EOL.
4400 (struct hppa_fix_struct): Delete fx_unwind field and all references.
4401 (fix_new_hppa): Last arg is now a pointer to an int. Do not
4402 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
4403 fixups, store 32bits of unwind information in the fx_addnumber
4405 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
4406 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
4407 pointer to 32 bits of unwind info.
4408 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
4409 pointer to the dummy symbol; set the addend field to fx_addnumber.
4410 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
4411 rather than &bfd_XXX_section.
4413 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4415 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
4416 value by one; discard adjustments previously being made. From
4419 VMS- and Vax-related changes from Pat Rankin:
4420 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
4421 * vmsconf.sh: no longer have make-gas.com echo text about needing
4422 to modify the gcc-vms driver when intending to use with gcc 1.x.
4423 * as.c (parse_options): suppress 'v' from std_short_options and
4424 eliminate VMS-specific conditional initialization;
4425 [default case]: check for '-v' if md_parse_options doesn't recognize
4427 [default case, #if VMS]: check for filename argument when '-v' seen;
4429 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
4430 for O_big literal operands (double floats and long long ints);
4431 [VMS, md_shortopts]: add second colon after 'v';
4432 (md_parse_options) [VMS, case 'v']: check for argument, so
4433 caller can handle `-v' w/o arg.

4437 * config/obj-coff.c (do_relocs_for): If TC_KEEP_FX_OFFSET
4438 is defined, put the tx_offset into the r_offset.

4478 Rewrite handling of program_transform_name.
4480 * configure.in: Test for functions unlink and delete.
4481 * as.h: If unlink isn't available but delete is, define unlink to

4486 * .gdbinit: Deleted.
4487 * aclocal.m4 (GAS_GDBINIT): Deleted.

4489 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
4490 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
4491 to ensure that older versions of autoconf aren't used.
4492 * Makefile.in: Added @configure_input@ line.
4493 (configure): Deleted rule.
4495 Tue Sep 13 12:08:20 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
4497 * config/obj-coff.c (fixup_segment): After handling the difference
4498 of two symbols from the same segment, set fx_subsy to NULL, to
4499 satisfy existing TC_COUNT_RELOC macros.

4524 * expr.c (make_expr_symbol): If operator is O_symbol and
4525 X_add_number is zero, just return the symbol. If operator is
4526 O_constant, resolve the symbol's value before returning.
4527 (operand): Permit use of "[]" for grouping.

4543 fixup is not local, to prevent relocations against externals from
4545 (md_assemble): Initialize disp_reloc field to NO_RELOC. Pass
4546 disp_reloc field to reloc() function, and use TC_RELOC to generate

4550 (i386_operand): Initialize disp_reloc field to NO_RELOC. Handle
4551 @GOTOFF, @PLT, @GOT operands. For GOTOFF relocations with local
4552 symbols, force generation of the section symbol.
4553 (md_estimate_size_before_relax): If GOT_symbol exists, decide

4573 * config/obj-elf.c (obj_elf_type): Rewrite to accept syntax
4574 reportedly to be used on Irix 6.
4576 * config/tc-mips.c (md_pseudo_table): Handle .globl and .global.
4577 (s_mips_globl): New static function; needed for Irix 5 support.
4578 * ecoff.c (ecoff_build_symbols): If BSF_FUNCTION is set for an
4579 external symbol with no type, set the type to st_Proc rather than
4580 st_Global. Don't set the index of an external st_Proc or
4581 st_StaticProc symbol unless it is also a local symbol.
4583 * read.c (read_a_source_file): The second argument to as_where is
4584 unsigned int *, not int *.
4586 Thu Sep 8 17:18:24 1994 Kung Hsu (kung@mexican.cygnus.com)

4608 * config/tc-{h8300,sh}.[ch] (tc_coff_symbol_emit): Function doing
4609 nothing becomes macro doing nothing.
4611 Wed Sep 7 19:10:09 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4613 * Makefile.in (Makefile): Depend on config.status.
4614 (config.status): Run config.status from . instead of srcdir.

4626 autoconf code should never let program_transform_name be empty.
4628 Update for autoconf beta 1.112:
4629 * aclocal.m4 (GAS_CHECK_DECL_NEEDED, GAS_WORKING_ASSERT): New
4631 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
4632 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
4633 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
4634 message to try to ease confusion about autoconf's

5484 (control_regs): New pointer.
5485 (m68k_ip): Use control_regs instead of testing CPU every time.

6039 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
6040 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
6042 * config/tc-ppc.c (ppc_size): New static variable.
6043 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
6044 (md_begin): If an instruction has a size specific flag set, only
6045 add it if we are assembling that size.
6047 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6049 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
6050 cross section PC relative relocs right for COFF and ELF.
6052 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

6060 the type of symbol set symbols which happen to be in the absolute
6061 or undefined section.

6065 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
6066 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
6067 and -many (all architectures).
6069 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

6078 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
6080 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
6081 branch with an instruction that uses $at, in case the branch is
6083 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
6084 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
6085 to make it pcrel_offset.
6086 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
6087 reloc->address; another gruesome hack to get gas reloc handling to
6090 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6092 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
6095 (emit_insn): New function.
6096 (md_assemble): Call it.
6097 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
6099 (lituse_pending): New variable. Set by anything that generates a
6100 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
6101 tested by code that might want to emit a LITUSE reloc.
6102 (emit_unaligned_io): New function. Currently calls md_assemble,
6103 but it should eventually be converted to generate the insn itself
6104 and call emit_insn directly.
6105 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
6106 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
6107 emit_bis_r): Likewise.

6116 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6118 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
6119 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
6120 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
6122 (mips_force_relocation): New function.
6123 (md_apply_fix): Set fixP->fx_done appropriately.
6124 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

6132 * config/tc-mips.c (enum mips_pic_level): New enum.
6133 (mips_pic): Change from int to enum mips_pic_level. Change all
6134 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
6135 (load_address): Handle EMBEDDED_PIC.
6136 (macro): Handle EMBEDDED_PIC in all PIC cases.
6137 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
6138 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
6139 -non_shared to use NO_PIC (this is how the Irix 5 assembler
6140 works). Do not permit -G with SVR4_PIC.
6141 (s_abicalls): Warn if -G was used, and force -G 0.
6142 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
6143 anything but a.out, not just for ELF. For ECOFF, don't generate a
6144 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
6146 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
6148 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6150 * config/tc-hppa.c (create_new_space): Use ints, not chars as
6151 parameters to avoid losing when compiling with HP CC.
6152 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
6154 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6156 * Makefile.in (config-stamp): If `defs' is defined, emit a
6157 preprocessor directive to create a macro named by this value into
6158 config.new; don't explicitly go for BFD_ASSEMBLER.
6159 * configure.in: Define `defs', not `BFDDEF'. Set it to
6160 MANY_SEGMENTS for any obj-coffbfd target.
6161 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
6162 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
6164 (LOCAL_LOADLIBES): Deleted.
6165 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
6166 * config/m88kcoff.mt (TDEFINES): Ditto.

6170 * config/sparc.mt: Deleted.
6171 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

6192 bfd_set_symtab is called.
6193 (dump_section_relocs): Note whether a symbol is a section symbol
6195 (adjust_reloc_syms): For now, always supply an absolute symbol for
6196 fixups without symbols but not yet `done'. Use section_symbol to
6197 get the symbol, instead of going directly for abs_symbol.
6198 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
6199 reloc is not a section symbol and is not in the symbol table.
6200 (set_symtab): New function, broken out from write_object_file.
6201 Counts symbol table instead of relying on an earlier count.
6202 (write_object_file): Call set_symtab, but do it after potentially
6203 invoking the *_frob_file macros. Don't bother counting symbols.
6204 Call symbol_remove, instead of expanding it in place. Moved the
6205 conditionalized `object_file_size' declaration down to
6206 conditionalized block where it's used. When using the absolute
6207 symbol for a fixup without a symbol, set sy_used_in_reloc.
6208 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
6209 the correct symbol for the absolute section.
6211 * subsegs.c (section_symbol): Use symbol_new instead of
6212 symbol_make, since we may want it to go into the symbol table.
6213 Make the new symbol have internal linkage. If
6214 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
6215 symbol with the newly created GAS symbol.
6216 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
6217 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

6222 (in_signed_range): New function.
6224 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
6225 (sparc_ip, label "immediate"): Reject constants for pcrel
6226 instructions only if the relocation type indicates a "call"
6227 instruction and the offset is within range of a "jmpl %g0". If
6228 it's not in range, use the absolute section symbol plus an offset.
6229 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
6231 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
6233 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
6236 * configure.in: Eliminated all targets using obj-coff but not
6237 defining BFD_ASSEMBLER; I think all such targets that are
6238 supported will be matched by real CPU-OS combinations earlier in
6240 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
6241 some comments about the dpx2 configuration, but left it disabled,
6242 since it couldn't be reached before.
6243 (target a29k-amd-ebmonold): Deleted.
6245 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

6253 the 'j' operand if there are no further alternatives for this
6256 * config/obj-coffbfd.c (adjust_stab_section): Initialize
6257 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
6258 is not SEG_UNKNOWN rather than checking whether it is >= 0.
6260 * config/tc-mips.c (mips_align): Take new argument, label, and use
6261 it instead of global insn_label.
6262 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
6263 call to mips_emit_delay and pass it to mips_align.
6265 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6267 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
6269 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
6270 argument to a .callinfo directive. Don't loop forever on errors.
6272 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
6273 use pre-defined registers as arguments.

6277 * write.c (write_object_file): Check both S_IS_LOCAL and
6278 S_IS_EXTERNAL when deciding whether to discard a symbol.
6280 * config-gas.com: Scan Makefile.in, not version.c, for current
6281 version number. Delete all versions of temp files when finished
6282 with them. Create config.h.
6284 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
6285 values to reduce number of lookups with S_GET_VALUE. Skip debug
6286 symbols to avoid "a really nasty bug". (From Holger Teutsch,
6287 holger@botbso.rhein-main.de.)
6288 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
6289 field. (Also from Holger Teutsch.) Watch for a would-be register
6290 mask that spans frags.
6292 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
6293 this_base, not line_base. (Patch from Andreas Arens,

6296 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
6297 look local if they're exported or undefined. Used to be done for
6300 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
6301 Get it from the looked-up symbol, instead of using the string from
6302 the input stream, which is no longer null-terminated.
6303 (LEX_PCT): New macro, defaults to 0.
6304 (lex_type): Use it for `%'.
6306 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

6356 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
6357 0xffff for 'j' to be compatible with MIPS assembler. These

8431 default is to assume production environment, and reject configs
8432 still being worked on. Mark Elf configurations (except sparc and
8433 i386) as developmental. Deleted cases matching some generic names
8434 in favor of more specific names. (E.g., when we get Alpha

8462 Add comments to functions. Delete unused functions, variables,
8463 #defines, etc. Delete unused members within structures. Delete
8464 ldil;ble hacks -- it is believed they were installed to work
8465 around old gas bugs. Avoid using mixed case for local
8466 functions, variables, and structures. Fix formatting problems
8467 not found by GNU-indent. Add FIXME notices for things which
8468 should be worked on the near future. Delete lots of old
8469 useless (1.36 PA-SOM) code.

8489 of elf32_symbol_type.
8490 (pa_export_args): Likewise.

8548 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
8550 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
8551 ELF, since the ELF object format does not have these type of
8552 relocations. Change the abort into as as_bad and return
8553 BFD_RELOC_NONE to silence compiler warnings.
8554 (md_assemble): Keep track of the instruction size. Allow white

10989 avoid some redefinition complaints on some systems.
10990 (const, volatile): Don't need these conditionally defined if we
10991 use CONST and VOLATILE from ansidecl.h.
10992 (seg_name): Use CONST, not const.

11040 dropping a space immediately following an identifier.

11114 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
11115 (struct loc, struct proc, struct file): Moved to tc-mips.c within
11116 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
11117 * config/tc-mips.c: Rearranged for ECOFF support. Added
11118 prototypes for all static functions. Moved existing minimal
11119 debugging format support info #ifndef OBJ_ECOFF blocks.
11120 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
11121 does not support a non sign extended high 16 bits reloc. Adjusted

11168 * make-gas.com: Find obstack.obj if it's not in the current
11170 * read.c (s_ignore): Don't declare is_end_of_line. It's
11171 redundant, and triggers a VMS gcc compiler bug.
11173 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
11174 current segment as an argument. (Ignored in all cases but VMS.)
11175 All callers and definitions changed.

11195 Call elf_xstabs for .stabs and .xstabs operators.
11197 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
11199 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
11202 * configure.in: mips-bsd configuration was missing format spec.
11205 * Makefile.in (Makefile): Depends on configure.in.
11207 * config/tc-mips.c (append_insn): Don't check for alignment of

11228 * config/tc-sparc.c (s_xword): Now call big_cons, so large
11229 constants are accepted, but symbolic values are not. GCC will not
11230 generate the latter currently.
11232 * frags.c (frag_init): New function.

11506 (operand): Treat zero byte as end-of-operand.
11508 * configure.in (per-target): Look for with_bfd_assembler option.
11509 For now, only accept "no", until the merge is done.
11511 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
11512 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
11513 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
11514 * read.c: Finish conversion to S_* macros in the VMS only
11515 parts of the program. Add "const" modifier to hex_value.
11516 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
11518 * expr.c: Add "const" modifier to hex_value.
11519 * symbols.c: Finish conversion to S_* macros in the VMS only
11520 parts of the program. Add "const" modifier to
11521 md_[long,short]_jump_size. Remove declaration of const_flag
11522 (which will be declared in obj-vms.h).
11523 * write.c: Add "const" modifier to md_[long,short]_jump_size.
11524 Fix arguments to VMS_write_object_file.
11525 * config-gas.com: New file. Script for VMS systems to set up the
11526 configuration to build gas for VMS, and create config.status.
11527 * make-gas.com: Redone to work with new scheme.

11534 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
11535 types of malformed stabs. Change parsing algorithm so that we are
11536 more certain of having all of the information that we need on hand.
11537 * obj-vms.c (final_forward_reference): New function, used to help
11538 resolve the data types of as many struct elements as possible

11556 SEG_DATA or SEG_E1 if needed.
11557 (s_lcomm): Likewise with bss_section.
11558 (s_fill): Use memset, not bzero.
11560 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

11596 declare with format attribute for -Wformat checking.
11598 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
11600 * app.c, config/tc-*.c: Don't include read.h, since it is already
11603 * These are based on patches from Minh Tran-le
11604 <mtranle@paris.intellicorp.com>.
11605 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
11606 obj_format coffbfd and gas_target i386coff for target.
11607 (i[34]86-*-isc*): New host (uses sysv).
11608 * config/i386aix.mt: Removed (no longer used).
11609 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
11610 (MINUS_G): Removed.
11611 (LDFLAGS): Added, defined as -shlib.
11612 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
11613 * config/te-sco386.h (LOCAL_LABEL): Don't define.
11614 (DOT_LABEL_PREFIX): Define.
11615 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
11616 name rather than L0\001.
11617 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
11619 * symbols.c, symbols.h (local_bss_counter): Removed.
11620 * write.c (write_object_file): bss no longer uses
11621 local_bss_counter. Pass correct data and bss size to
11622 VMS_write_object_file.

11628 (size_section): Restored sanity check.
11629 (do_relocs_for): Base section address on s_paddr rather than
11630 computing it. Adjust a29k R_IHIHALF special case to account for
11631 section paddr (used to require paddr to be zero). If there are no
11632 reclos, set s_relptr to 0. Set relocation size in object_headers.
11633 (fill_section): Always set s_vaddr here, removing
11634 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
11635 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
11636 Set STYP_INFO for .comment.
11637 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
11638 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

11642 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
11643 set s_vaddr here. If string_byte_count remains 4, set it back to
11644 0, and only write strings out if there are some. Call
11645 fill_section before do_relocs_for and do_linenos_for.
11646 (obj_coff_section): Handle optional quoted second argument giving
11647 section characteristics.
11648 (obj_coff_bss): Added to handle .bss.

11669 (do_scrub_next_char): For \", return " not '.
11670 (symbol_chars): Now const.
11672 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
11673 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
11675 * config/obj-coff.h: Don't use #elif.
11677 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
11678 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
11680 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

11704 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
11705 using ZERO_BASED_SEGMENTS.
11706 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
11707 never set segment address for SEG_E2 (.bss) and don't write out
11708 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
11709 (obj_coff_endef): Don't merge labels or symbols awaiting forward
11710 definitions, and don't merge tags with non-tags. Check for .bf
11711 rather than just checking whether the second character is b and
11712 the third character is f.
11713 (obj_coff_val): gcc can generate values which we don't handle
11714 correctly; discard information for now, since it only affects the
11715 debugging information.

11717 (yank_symbols): Don't merge labels.
11718 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

12010 * listing.c (debugging_pseudo): Add stabs and stabn as things to
12013 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
12015 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
12016 sections starting from zero, rather than making them consecutive.
12017 This makes subsequent reloc calculations easier, esp if the object
12018 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
12019 allocate lcomm in .data rather than in .bss. It seems that some
12020 tools can't cope with a non-zero sized bss before linkage.

12024 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
12025 throughout. That enum no longer means what we thought it meant.
12027 * tc-m68k.c (md_assemble, md_parse_option): Handle new
12028 "-mno-688[58]1" options.

12046 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
12048 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
12049 .word is < -32768 or > 32767. The -J flag causes the error to be
12050 ignored. This is to catch over-sized switches generated by gcc on
12051 systems which don't support the broken .word hack.
12052 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
12053 write.c (fixup_segment): check for signed .word overflow if
12054 WARN_SIGNED_OVERFLOW_WORD.

12095 (fill_section) added rs_machine_dependent case
12096 (write_object_file) call fixup_mdeps
12097 (fixup_segment) set fx_subsy to 0.
12098 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
12100 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
12103 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

12132 * config/tc-m68k.c (init_table): Now const. Always include 68851
12133 data, so that "bc" is available to 68040 cache instructions.
12134 Added "tt0", "tt1", and 68ec030 variants.
12135 (md_assemble): Complain if 68000 (only) and 68881 are specified.

12159 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
12160 so that we can assemble hand-written libgcc code.
12162 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
12164 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
12165 has already been formatted (but may still contain %-characters).
12166 (as_bad): Likewise.
12168 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
12170 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
12171 written with indirection on the last two operands, which can be
12172 either data or address registers. Added a new operand type 'r'
12173 which accepts either register type. Added '(' to notend stuff in
12174 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

12487 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
12489 * write.{c,h} (fix_new): Make these declarations consistent.
12491 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
12493 * Makefile.in (strerror.o): Add rule so that broken Sun make can
12496 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
12498 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
12500 * expr.c (operand): if can't work out what sort of operand it is,
12501 then look through FLT_CHARS for a hint.
12503 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
12505 * Makefile.in, configure.in: removed traces of namesubdir,
12506 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
12507 copyrights to '92, changed some from Cygnus to FSF.
12509 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
12510 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
12511 copyrights to '92, changed some from Cygnus to FSF.
12513 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
12515 * expr.c: If an expression is single comma, then return with
12516 SEG_ABSENT rather than an error - since the sparc front end does
12517 really strange things with things like fbge,a
12519 * as.h: include bfd.h if using many sections
12520 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
12521 local labels didn't work.
12522 * listing.c (list_symbol_table): don't core dump when there's no
12524 * write.c, write.h: call fix_new with the right number of args on
12526 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
12529 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
12531 * app.c: MRI compatibility - allow single quote to start a string.
12532 * as.c: fix typo recently introduced.
12533 * as.h : Don't include aout/reloc.h - it's not right for COFF!
12534 * expr.c: Much rewriting, to accomodate MRI syntax for
12535 expressions. Also easier to read now.
12536 * listing.c: Put back defuns
12537 * read.c: modified to accept MRI syntax, put back listing pseudo
12538 ops so that an assembler built with NO_LISTING ignores list ops
12540 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
12541 machine is a SPARC or a 29K.
12542 * config/obj-aout.c: added s_sect pseudo op
12543 * config/obj-coffbfd.c: lints, set the filehdr flags right and
12544 fill in the timestamp.
12545 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
12546 anymore, define all the relocs which the tc-<x> bit will use so we
12547 can translate from them to the coff types.
12548 * config/tc-a29k.c: reloc_type isn't ane enum any more
12549 * config/tc-m68k.c: Added NO_RELOC definition.
12551 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
12553 * Makefile.in: put header files before C source for TAGS; remove
12554 references to non-existent syscalls.h.
12556 * read.c, write.c subsegs.c: back out the .bss changes.
12558 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
12560 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
12562 * a.out.h: removed.
12564 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
12566 * symbols.c (local_label_name): symbols now start with ^A.
12568 * read.c, subsegs.c, write.c obj-coff.c: added handling of
12569 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
12570 generate these sections. .align: will use NOP_OPCODE or 0
12571 for padding. This is just for being nice to the
12574 * expr.c (operand): changed to generate local label "\001L0"
12575 starting with a ^A so that it is recognized as a local label.
12577 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
12579 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
12580 i/o opcodes - inb, inw, outb and outw. string manipulation with
12581 att syntax - scmp, slod, smov, ssca, ssto.
12583 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
12584 to just after .file .
12586 In obj_crawl_symbol_chain() where it tries to put the external
12587 symbols apart, with the condition:
12588 (!S_IS_DEFINED(symbolP) &&
12589 !S_IS_DEBUG(symbolP) &&
12590 !SF_GET_STATICS(symbolP))
12591 it was moving too many symbols out. So I switch it back to the
12593 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
12595 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
12596 so that we don't use the F_RELFLG which make the linker complain
12597 that somebody has stripped the relocation info.
12599 Also, the AIX ld program require that the relocation table
12600 is sorted by r_vaddr like the standard ATT assembler does.
12602 [he also changed the sizeof(struct ...)'s into the coff
12603 style FOOSZ macros. I'm not sure this is right, but I can't
12604 remember why. xoxorich.]
12606 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
12608 * Makefile.in, configure.in, doc: use the doc. Build it, install
12611 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
12613 * read.c: white space and comments only.
12615 * configure.in: use the new atof-ns32.c for ns32k.
12617 * write.c: comment change only.
12619 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
12620 aren't yet integrated.
12622 * tc-i860.[hc]: blew off the dust. Something must still be done
12623 about conflicting relocation types.
12625 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
12628 * tc-i960.c, tc-sparc.c: white space and comments only.
12630 * tc-a29k.h: delete duplicate macro definition.
12632 * new file atof-ns32k.c copied from hack's last unreleased gas.
12634 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
12636 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
12639 * nearly everything. flush ChangeLog, package as gas-1.92.1.
12640 ChangeLog's prior to this are sketchy at best. I have logs.
12641 They just aren't ChangeLogs.
