2440 Add a space after "pc-relative" in the error message.
2441 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
2442 BFD_RELOC_386_GOTOFF relocs.

2484 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2486 * configure.in: Set bfd_gas for all sparc targets in one place,
2487 instead of separately for each. Correctly handle user-supplied
2488 "--enable-bfd-gas" option.
2490 * gdbinit.in: Move "break abort" to end, in case gdb complains.

2500 (indent_level): No longer static.
2501 (print_symbol_value_1): Don't print frag address if it matches

2505 (print_expr_1): Fix whitespace before printing X_add_number.
2507 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
2508 not symbol_new, for symbols holding expression values.
2509 * expr.h (make_expr_symbol): Move declaration here.
2510 * write.c (fix_new_exp): Handle O_add by creating an
2511 expression-valued symbol, and calling fix_new_exp recursively.
2512 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
2513 undefined symbol and a constant, fold the constant into the fixup,
2514 and refer to the undefined symbol directly. Then process the
2515 fixup again from scratch.
2516 (write_object_file): Before calling adjust_reloc_syms, make a pass
2517 through the symbol list trying to resolve values.
2519 * write.c (print_fixup): New routine, for debugging.
2520 (write_relocs): Call bfd_install_relocation. Deleted various
2521 hacks for working around problems with bfd_perform_relocation.
2523 * Makefile.in (VERSION): Update to 2.4.90.
2525 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

2538 * write.c (write_relocs): Add file name and line number to
2539 as_fatal calls. Handle bfd_reloc_overflow case specifically when

2544 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
2545 here. Use them for deciding which PRINTF*LIKE macro definitions

2548 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
2549 default definitions matching what we were doing before.
2550 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
2551 always use the varargs form if not using stdarg. It's safe to
2552 always use vfprintf, because libiberty will provide it if the
2553 native system doesn't. Also, always make format be const.
2554 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

2570 deciding whether to record it.
2571 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
2572 false (if defined) as well as checking for reg_section.
2573 (listing_listing): Iterate fetching lines while line number is too
2574 low, and we haven't run off the end of the input file.
2576 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
2578 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

2587 * config/ho-*.h: Now-unused files deleted.
2589 * symbols.c (copy_symbol_attributes): New function. Copies BFD
2590 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
2591 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
2592 zero. Don't call obj_frob_forward_symbol.

2601 md_estimate_size_before_relax, md_ri_to_chars,
2602 md_create_short_jump, md_create_long_jump.
2603 (brtab_emit): Use data_section, not SEG_DATA.
2605 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2607 * config/vms-conf.h: new file, manually derived from conf.in.

2618 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
2619 from the csect of the enclosing block.
2621 * config/tc-mips.c (insns_since_cache_access): Remove.
2622 (append_insn): Remove setting of insns_since_cache_access, and
2623 special 4600 handling; it turns out not to be required.
2625 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2627 * config/tc-mips.c (md_shortopts): Remove E.
2628 (md_longopts): Add EB and EL.
2629 (md_parse_option): Handle -EB and -EL as separate options, rather

2639 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
2641 * configure.in: Test for remove, not delete. Fix cross-assembler

2647 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
2648 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
2649 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.

2653 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
2654 many others): new macros; values obtained from "DSTRECRDS.SDL".
2655 * config/obj-vms.h (various): use them.
2656 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
2657 representation (only enum bitfields can avoid being bitstrings).
2658 (bitfield_suffix, setup_basic_type): new routines.
2659 (VMS_typedef_parse): use them. Now recognize bitfields of all
2660 integral types, not just type `int'. Caveat: the representation
2661 used for bitfields still does not work for objects placed in
2662 registers, and gcc's optimizer sometimes puts small structs there.
2664 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2666 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
2667 bit from const_flag.
2668 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.

2673 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
2674 (vms_check_for_special_label): new routine (tc_frob_label).
2675 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
2676 and `gcc2_compiled.' labels; they won't reach here any more.
2677 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
2678 double', use `vax_g_doubles' flag to select type of double.
2679 (VMS_write_object_file) [traceback setup]: don't pass symbols
2680 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
2681 and TBT_Routine_End functions.

2685 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
2686 S_GET_VALUE() to avoid many repeated function calls.
2687 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
2688 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
2689 gets requested. [All the HACK_DEC_C_STARTUP code appears to
2690 be obsolete; gcc does it automatically for vms target. It's
2691 also misnamed, because it is for the "VAX C" run-time library,
2692 not the newer "DEC C" one which has much different startup code.]
2693 {various}: use `S_SET_xxx(symbol,new_value)' rather than
2694 `S_GET_xxx(symbol) = new_value'.
2696 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2698 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
2699 not &bfd_abs_section.
2701 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2703 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
2705 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
2707 * expr.c (expr): Don't reduce the difference of two symbols in the
2708 same frag if the symbols are not in normal sections.
2710 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
2711 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
2712 (obj_attach_unwind_info): Do not define. Not needed anymore.
2713 * config/tc-hppa.c: Delete whitespace at EOL.
2714 (struct hppa_fix_struct): Delete fx_unwind field and all references.
2715 (fix_new_hppa): Last arg is now a pointer to an int. Do not
2716 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
2717 fixups, store 32bits of unwind information in the fx_addnumber
2719 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
2720 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
2721 pointer to 32 bits of unwind info.
2722 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
2723 pointer to the dummy symbol; set the addend field to fx_addnumber.
2724 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
2725 rather than &bfd_XXX_section.
2727 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2729 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
2730 value by one; discard adjustments previously being made. From
2733 VMS- and Vax-related changes from Pat Rankin:
2734 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
2735 * vmsconf.sh: no longer have make-gas.com echo text about needing
2736 to modify the gcc-vms driver when intending to use with gcc 1.x.
2737 * as.c (parse_options): suppress 'v' from std_short_options and
2738 eliminate VMS-specific conditional initialization;
2739 [default case]: check for '-v' if md_parse_options doesn't recognize

2743 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
2744 for O_big literal operands (double floats and long long ints);
2745 [VMS, md_shortopts]: add second colon after 'v';
2746 (md_parse_options) [VMS, case 'v']: check for argument, so
2747 caller can handle `-v' w/o arg.

2792 Rewrite handling of program_transform_name.
2794 * configure.in: Test for functions unlink and delete.

2800 * .gdbinit: Deleted.
2801 * aclocal.m4 (GAS_GDBINIT): Deleted.

2805 to ensure that older versions of autoconf aren't used.
2806 * Makefile.in: Added @configure_input@ line.
2807 (configure): Deleted rule.
2809 Tue Sep 13 12:08:20 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2811 * config/obj-coff.c (fixup_segment): After handling the difference
2812 of two symbols from the same segment, set fx_subsy to NULL, to

3872 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
3873 for gcc2's predefined types "long double" (same as double, as

3877 "complex float", "complex double", and "complex long double" are
3880 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
3881 of 0, because the latter indicates success rather than failure

4235 * expr.c (operand): Try to parse "0f" and "0b" sequences as
4236 floating point and binary numbers respectively; if it doesn't
4237 work, treat them as local labels.
4239 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
4240 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
4242 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
4244 * vmsconf.sh: In generated file, get ".obj" suffix right, build
4245 source files from other directories into objects in the current
4246 directory, and specify PSECT attributes explicitly to linker.
4247 Also added missing label.
4248 * Makefile.in (stamp-mk.com): Reference new variable
4249 VMS_OTHER_OBJS for list of non-local object files, instead of

4264 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
4265 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
4266 argument, the reloc type.
4267 (load_register): Pass reloc type to macro_build for 'u'.
4268 (macro): Likewise. For M_LA_AB permit a difference expression
4269 when generating embedded PIC code between an arbitrary symbol and
4270 a symbol in the .text section.
4271 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
4272 BFD_RELOC_PCREL_LO16 to be emitted.

4280 * subsegs.c (subsegs_begin): Call memset with args in the correct
4282 (subseg_get): Clear newly allocated seginfo, set its pointer slots
4283 to NULL instead of 0.

4287 * config/tc-hppa.c (pa_procend): Handle case where label was
4288 defined after the .proc directive.
4290 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
4291 procend for a procedure without a name.

4312 (hppa_tc_symbol): Likewise.
4314 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
4315 elf_tc_make_sections stuff. It was there to support PA braindamage
4316 which has been fixed, and in the case of elf_tc_make_sections is
4317 redundant with elf_tc_final_processing.
4319 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4321 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

4337 don't spew remainder of input file in error message.
4338 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
4339 message with reloc type and try to process remainder of file.
4341 * doc/Makefile.in (install-info-as, install-info-gasp): New
4342 targets, now explicitly checking $(srcdir) for info files.
4343 (install-info): Depend on both of them; do nothing more.

4347 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
4349 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4351 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
4352 flag rather than signedp field. Only permit extended range if
4353 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
4354 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
4356 * config/tc-ppc.c (ppc_size): New static variable.
4357 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
4358 (md_begin): If an instruction has a size specific flag set, only
4359 add it if we are assembling that size.
4361 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4363 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
4364 cross section PC relative relocs right for COFF and ELF.
4366 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4368 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
4369 (OBJ_PROCESS_STAB): Don't define.
4371 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4373 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
4374 the type of symbol set symbols which happen to be in the absolute
4375 or undefined section.
4377 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
4379 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
4380 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
4381 and -many (all architectures).
4383 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4385 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
4386 involving a function symbol which is not a plabel to zero.
4387 (md_apply_fix): Never pass a function symbol to field_adjust.
4389 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4391 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
4392 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
4394 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
4395 branch with an instruction that uses $at, in case the branch is
4397 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
4398 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
4399 to make it pcrel_offset.
4400 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
4401 reloc->address; another gruesome hack to get gas reloc handling to
4404 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4406 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
4409 (emit_insn): New function.
4410 (md_assemble): Call it.
4411 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
4413 (lituse_pending): New variable. Set by anything that generates a
4414 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
4415 tested by code that might want to emit a LITUSE reloc.
4416 (emit_unaligned_io): New function. Currently calls md_assemble,
4417 but it should eventually be converted to generate the insn itself
4418 and call emit_insn directly.
4419 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
4420 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
4421 emit_bis_r): Likewise.
4422 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
4423 (alpha_ip, label get_macro): Don't emit the final instruction if
4425 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
4426 unaligned memory access macros.
4427 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
4428 the value can't be resolved.
4430 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4432 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
4433 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
4434 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
4436 (mips_force_relocation): New function.
4437 (md_apply_fix): Set fixP->fx_done appropriately.
4438 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

4446 * config/tc-mips.c (enum mips_pic_level): New enum.
4447 (mips_pic): Change from int to enum mips_pic_level. Change all
4448 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
4449 (load_address): Handle EMBEDDED_PIC.
4450 (macro): Handle EMBEDDED_PIC in all PIC cases.
4451 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
4452 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
4453 -non_shared to use NO_PIC (this is how the Irix 5 assembler
4454 works). Do not permit -G with SVR4_PIC.
4455 (s_abicalls): Warn if -G was used, and force -G 0.
4456 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
4457 anything but a.out, not just for ELF. For ECOFF, don't generate a
4458 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
4460 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
4462 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4464 * config/tc-hppa.c (create_new_space): Use ints, not chars as
4465 parameters to avoid losing when compiling with HP CC.
4466 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
4468 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4470 * Makefile.in (config-stamp): If `defs' is defined, emit a
4471 preprocessor directive to create a macro named by this value into
4472 config.new; don't explicitly go for BFD_ASSEMBLER.
4473 * configure.in: Define `defs', not `BFDDEF'. Set it to
4474 MANY_SEGMENTS for any obj-coffbfd target.
4475 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
4476 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
4478 (LOCAL_LOADLIBES): Deleted.
4479 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
4480 * config/m88kcoff.mt (TDEFINES): Ditto.
4481 * config/ebmon29k.mt: Deleted.
4482 * config/h8300hds.mt: Deleted.
4483 * config/ic960coff.mt: Deleted.
4484 * config/sparc.mt: Deleted.
4485 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
4486 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
4487 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
4488 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

4506 bfd_set_symtab is called.
4507 (dump_section_relocs): Note whether a symbol is a section symbol
4509 (adjust_reloc_syms): For now, always supply an absolute symbol for
4510 fixups without symbols but not yet `done'. Use section_symbol to
4511 get the symbol, instead of going directly for abs_symbol.
4512 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
4513 reloc is not a section symbol and is not in the symbol table.
4514 (set_symtab): New function, broken out from write_object_file.
4515 Counts symbol table instead of relying on an earlier count.
4516 (write_object_file): Call set_symtab, but do it after potentially
4517 invoking the *_frob_file macros. Don't bother counting symbols.
4518 Call symbol_remove, instead of expanding it in place. Moved the
4519 conditionalized `object_file_size' declaration down to
4520 conditionalized block where it's used. When using the absolute
4521 symbol for a fixup without a symbol, set sy_used_in_reloc.
4522 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
4523 the correct symbol for the absolute section.
4525 * subsegs.c (section_symbol): Use symbol_new instead of
4526 symbol_make, since we may want it to go into the symbol table.
4527 Make the new symbol have internal linkage. If
4528 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
4529 symbol with the newly created GAS symbol.
4530 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
4531 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
4533 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
4535 * config/tc-sparc.c: Include subsegs.h.
4536 (in_signed_range): New function.
4538 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
4539 (sparc_ip, label "immediate"): Reject constants for pcrel
4540 instructions only if the relocation type indicates a "call"
4541 instruction and the offset is within range of a "jmpl %g0". If
4542 it's not in range, use the absolute section symbol plus an offset.
4543 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
4545 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
4547 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
4550 * configure.in: Eliminated all targets using obj-coff but not
4551 defining BFD_ASSEMBLER; I think all such targets that are
4552 supported will be matched by real CPU-OS combinations earlier in
4554 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
4555 some comments about the dpx2 configuration, but left it disabled,
4556 since it couldn't be reached before.
4557 (target a29k-amd-ebmonold): Deleted.
4559 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4566 * config/tc-mips.c (mips_ip): Only accept overly large values for
4567 the 'j' operand if there are no further alternatives for this
4570 * config/obj-coffbfd.c (adjust_stab_section): Initialize
4571 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
4572 is not SEG_UNKNOWN rather than checking whether it is >= 0.
4574 * config/tc-mips.c (mips_align): Take new argument, label, and use
4575 it instead of global insn_label.
4576 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
4577 call to mips_emit_delay and pass it to mips_align.
4579 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4581 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
4583 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
4584 argument to a .callinfo directive. Don't loop forever on errors.
4586 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
4587 use pre-defined registers as arguments.

4591 * write.c (write_object_file): Check both S_IS_LOCAL and
4592 S_IS_EXTERNAL when deciding whether to discard a symbol.
4594 * config-gas.com: Scan Makefile.in, not version.c, for current
4595 version number. Delete all versions of temp files when finished
4596 with them. Create config.h.
4598 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
4599 values to reduce number of lookups with S_GET_VALUE. Skip debug
4600 symbols to avoid "a really nasty bug". (From Holger Teutsch,
4601 holger@botbso.rhein-main.de.)
4602 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
4603 field. (Also from Holger Teutsch.) Watch for a would-be register
4604 mask that spans frags.
4606 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
4607 this_base, not line_base. (Patch from Andreas Arens,
4608 ari@obelix.av.rwth-aachen.de.)
4610 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
4611 look local if they're exported or undefined. Used to be done for
4614 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
4615 Get it from the looked-up symbol, instead of using the string from
4616 the input stream, which is no longer null-terminated.
4617 (LEX_PCT): New macro, defaults to 0.
4618 (lex_type): Use it for `%'.
4620 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
4621 (vip_op): Now static, and returns void. Callers changed. Added
4623 (vip): Ditto. Call as_fatal directly if a program bug is
4625 (op_hash): Let default initialization suffice.

4658 (NO_RELOC): Undefine before defining as part of enum reloc_type.
4660 * config/tc-alpha.c: Add comment questioning need for all the
4661 characters in FLT_CHARS.

4670 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
4671 0xffff for 'j' to be compatible with MIPS assembler. These
4672 numbers are actually treated as negative.
4674 Thu Mar 10 13:36:29 1994 Doug Evans (dje@canuck.cygnus.com)
4676 * config/tc-sparc.h (LOCAL_LABEL): Local labels are .Lfoo.

4681 (obj_coff_section): Declare.
4682 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
4683 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

6085 (mips_ip): Don't permit anything but a number after $ for a
6086 coprocessor register. Don't use .lit4 or .lit8 sections when

6255 Delete dead code. Simplify.
6256 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
6257 applied are in range. Use bfd_put_32 rather than inserting each

6336 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
6337 standard hpux include files to pick up various function decls.
6339 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

6373 an example of marker relocations.
6374 * write.c (write_relocs): Instead of assuming size of a relocation
6375 is 4 bytes, pick up the size from relocation itself.

6627 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
6628 the table, require that the one without bit 0x1000000 set come
6629 first. Require further that it be case 'b' or 'P'. The a29k
6630 opcode table already meets these constraints.
6631 (machine_ip): When handling case 'i' or 'A', make sure that the
6632 appropriate opcode really exists by looking at the next entry in

6687 * write.c (write_relocs): For relocs that are pc_relative and
6688 pcrel_offset and not partial_inplace, adjust reloc->addend to

6741 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
6743 * configure.in: Set bfd_gas for all sparc targets. Added facility
6744 for keeping or rejecting configurations still under development;
6745 default is to assume production environment, and reject configs
6746 still being worked on. Mark Elf configurations (except sparc and
6747 i386) as developmental. Deleted cases matching some generic names
6748 in favor of more specific names. (E.g., when we get Alpha

6765 through inclusion of tc-hppa.h. Delete all forward declarations
6766 for functions only used within tc-hppa.c, likewise for structures,
6767 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
6768 conditional code in a few small places.
6770 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
6771 structures, global variables, forward declarations together.

6773 conditional code -- try to group conditional code together
6774 into a few places. Make all functions and variables which
6775 are only used within tc-hppa.c static. PARAMize all functions.
6776 Add comments to functions. Delete unused functions, variables,
6777 #defines, etc. Delete unused members within structures. Delete
6778 ldil;ble hacks -- it is believed they were installed to work
6779 around old gas bugs. Avoid using mixed case for local
6780 functions, variables, and structures. Fix formatting problems
6781 not found by GNU-indent. Add FIXME notices for things which
6782 should be worked on the near future. Delete lots of old
6783 useless (1.36 PA-SOM) code.
6785 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
6786 field of the fixS structure. Needed to build unwind
6787 descriptors correctly.

6811 * config/tc-hppa.c: (md_section_align): Align all sections to
6812 a multiple of the section alignment rather than always a
6815 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
6816 bits are zero (eg they specify no relocations), then do not even
6817 bother adding their entries to thesymextn section.

6860 instead add a second loop over special_chars. Set alignment
6861 of text, data and bss sections to 4.
6862 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
6864 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
6865 ELF, since the ELF object format does not have these type of
6866 relocations. Change the abort into as as_bad and return
6867 BFD_RELOC_NONE to silence compiler warnings.
6868 (md_assemble): Keep track of the instruction size. Allow white
6869 space between the $ and the constant for compatibility with older
6870 gases and other assemblers.
6871 (i386_operand): Skip spaces between $ and expression.

7915 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
7916 case to set obj_format=elf. Must go before i386-*-sysv* case that
7917 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
7918 *-*-solaris case, and move to before *-sysv* case that wants to
7919 set obj_format to coff.

7945 * Extensive changes to permit symbols to contain any expression
7946 type and to delay the computation of the expression until the
7947 value is actually needed. This permits setting symbols to values
7948 calculated based on object code size. Expressions were changed to
7949 no longer be in a section, to stop the overloading of segment and
7950 expression type that previously occurred.
7952 * as.c (big_section, pass1_section, diff_section, absent_section):
7954 (expr_section): Added (used for dummy symbols which hold

8038 (previous_section, previous_subsection): New vars.
8039 (obj_elf_section): Save current place in case DWARF code wants us
8040 to pop back to it. Handle unquoted section name as well as quoted
8041 section name. Don't crash on invalid strings.
8042 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
8045 * config/obj-elf.h: Don't include struc-symbol.h.

8154 sy_resolved and sy_resolving single bit fields.
8155 * symbols.c (symbol_new): Don't initialize sy_forward field.

9356 lines; I don't think that can be done portably.
9357 * config/tc-mips.c (macro): Use $AT if target register is zero in
9358 load instruction, which it can be for a floating point load.

9482 * make-gas.com: Find obstack.obj if it's not in the current
9484 * read.c (s_ignore): Don't declare is_end_of_line. It's
9485 redundant, and triggers a VMS gcc compiler bug.
9487 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
9488 current segment as an argument. (Ignored in all cases but VMS.)
9489 All callers and definitions changed.

9513 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
9516 * configure.in: mips-bsd configuration was missing format spec.
9519 * Makefile.in (Makefile): Depends on configure.in.
9521 * config/tc-mips.c (append_insn): Don't check for alignment of
9522 frag in memory; alignment of instructions in section is a separate

9543 constants are accepted, but symbolic values are not. GCC will not
9544 generate the latter currently.
9546 * frags.c (frag_init): New function.
9547 (zero_address_frag, bss_address_frag): Now initialized at run
9549 * as.c (main): Call frag_init.

9825 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
9826 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
9827 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
9828 * read.c: Finish conversion to S_* macros in the VMS only
9829 parts of the program. Add "const" modifier to hex_value.
9830 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
9832 * expr.c: Add "const" modifier to hex_value.
9833 * symbols.c: Finish conversion to S_* macros in the VMS only
9834 parts of the program. Add "const" modifier to
9835 md_[long,short]_jump_size. Remove declaration of const_flag
9836 (which will be declared in obj-vms.h).
9837 * write.c: Add "const" modifier to md_[long,short]_jump_size.
9838 Fix arguments to VMS_write_object_file.
9839 * config-gas.com: New file. Script for VMS systems to set up the
9840 configuration to build gas for VMS, and create config.status.
9841 * make-gas.com: Redone to work with new scheme.
9842 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
9844 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
9845 will swap bytes if needed on a big endian system. Use throughout
9847 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
9848 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
9849 types of malformed stabs. Change parsing algorithm so that we are
9850 more certain of having all of the information that we need on hand.
9851 * obj-vms.c (final_forward_reference): New function, used to help
9852 resolve the data types of as many struct elements as possible
9853 when some part of the struct is not fully defined by the compiler.
9854 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
9856 * obj-vms.c (VMS_write_object_file): Define all vtable psects
9857 as symbols as well in the object file. Look for external functions
9858 that start with "__vt.", and turn them into variables, since the
9859 g++ compiler is incapable of doing this.
9860 * tc-vax.c: Add '1' option for backward compatibility with older GCC
9862 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
9863 * input-scrub.c (as_where): Fix bug where as would crash if we did not
9864 have the name of the source file yet.
9865 * config/ho-vms.h: define HO_VMS, not HO_VAX.
9867 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
9869 * read.c (s_data): Always use "data_section", since it'll map to
9870 SEG_DATA or SEG_E1 if needed.
9871 (s_lcomm): Likewise with bss_section.
9872 (s_fill): Use memset, not bzero.
9874 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

9890 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
9891 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

9895 (section_alignment): Declare only if not BFD_ASSEMBLER.
9896 (big_section, reg_section, pass1_section, diff_section,
9897 absent_section, text_section, data_section, bss_section): If
9898 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
9899 mapping to segT enum values.
9900 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
9901 if these are used or defined, if BFD_ASSEMBLER.
9902 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
9903 subseg_new split into two functions.
9904 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
9906 * as.h (volatile): Don't define if already defined.
9907 (had_errors, had_warnings): Provide prototypes for ANSI C even if
9909 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
9910 declare with format attribute for -Wformat checking.
9912 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
9914 * app.c, config/tc-*.c: Don't include read.h, since it is already
9917 * These are based on patches from Minh Tran-le
9918 <mtranle@paris.intellicorp.com>.
9919 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
9920 obj_format coffbfd and gas_target i386coff for target.
9921 (i[34]86-*-isc*): New host (uses sysv).
9922 * config/i386aix.mt: Removed (no longer used).
9923 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
9925 (LDFLAGS): Added, defined as -shlib.
9926 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
9927 * config/te-sco386.h (LOCAL_LABEL): Don't define.
9928 (DOT_LABEL_PREFIX): Define.
9929 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
9930 name rather than L0\001.
9931 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
9933 * symbols.c, symbols.h (local_bss_counter): Removed.
9934 * write.c (write_object_file): bss no longer uses
9935 local_bss_counter. Pass correct data and bss size to
9936 VMS_write_object_file.

9942 (size_section): Restored sanity check.
9943 (do_relocs_for): Base section address on s_paddr rather than
9944 computing it. Adjust a29k R_IHIHALF special case to account for
9945 section paddr (used to require paddr to be zero). If there are no
9946 reclos, set s_relptr to 0. Set relocation size in object_headers.
9947 (fill_section): Always set s_vaddr here, removing
9948 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
9949 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
9950 Set STYP_INFO for .comment.
9951 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
9952 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

9954 H_{SET,GET}_* macros.
9955 (do_linenos_for): Set lineno size in object_headers.
9956 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
9957 set s_vaddr here. If string_byte_count remains 4, set it back to
9958 0, and only write strings out if there are some. Call
9959 fill_section before do_relocs_for and do_linenos_for.
9960 (obj_coff_section): Handle optional quoted second argument giving
9961 section characteristics.
9962 (obj_coff_bss): Added to handle .bss.
9963 (obj_coff_ident): Added to handle .ident (puts string in .comment

9983 (do_scrub_next_char): For \", return " not '.
9984 (symbol_chars): Now const.
9986 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
9987 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
9989 * config/obj-coff.h: Don't use #elif.
9991 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
9992 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
9994 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
9996 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

10016 SEG_BSS, fill with NOP_OPCODE.
10017 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
10018 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
10019 using ZERO_BASED_SEGMENTS.
10020 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
10021 never set segment address for SEG_E2 (.bss) and don't write out
10022 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
10023 (obj_coff_endef): Don't merge labels or symbols awaiting forward
10024 definitions, and don't merge tags with non-tags. Check for .bf
10025 rather than just checking whether the second character is b and
10026 the third character is f.
10027 (obj_coff_val): gcc can generate values which we don't handle
10028 correctly; discard information for now, since it only affects the
10029 debugging information.

10031 (yank_symbols): Don't merge labels.
10032 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

10292 * tc-z8k.c: lots of bug fixes
10294 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
10296 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
10297 #elif, since it is not supported by old compilers.
10298 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
10299 couple of expressions in tc-m68k.c.
10301 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10303 * read.c (cons): If NO_RELOC is defined, use it.

10309 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
10310 local labels to start with a .) and set REGISTER_PREFIX to %.
10311 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
10313 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

10320 * messages.c: If __STDC__ is not defined, define NO_STDARG.
10322 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
10324 * listing.c (debugging_pseudo): Add stabs and stabn as things to
10327 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
10329 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
10330 sections starting from zero, rather than making them consecutive.
10331 This makes subsequent reloc calculations easier, esp if the object
10332 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
10333 allocate lcomm in .data rather than in .bss. It seems that some
10334 tools can't cope with a non-zero sized bss before linkage.
10336 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10338 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10339 throughout. That enum no longer means what we thought it meant.
10341 * tc-m68k.c (md_assemble, md_parse_option): Handle new
10342 "-mno-688[58]1" options.
10344 * tc-m68k.c: Added CPU32 support.
10346 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10348 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.

10357 * Makefile.in (install): if $(tooldir) exists, install as in
10360 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10362 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10363 .word is < -32768 or > 32767. The -J flag causes the error to be
10364 ignored. This is to catch over-sized switches generated by gcc on
10365 systems which don't support the broken .word hack.
10366 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10367 write.c (fixup_segment): check for signed .word overflow if
10368 WARN_SIGNED_OVERFLOW_WORD.
10370 * write.c (fixup_segment): fixed missing parens in expression
10371 checking for byte or word overflow.
10373 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

10389 * input-scrub.c (input_scrub_push): call input_file_begin, not
10391 messages.c (as_perror): print ": " between the passed in error and
10392 the strerror, like perror does.
10394 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

10401 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
10402 Motorola and MIT syntax; gas can now assemble either type of
10404 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
10405 From Steve Chamberlain:
10406 m68kcoff.mt: for m68k COFF.
10407 obj-coffbfd.c: (fixup_mdeps) added
10408 (size_section) removed bad sanity check
10409 (fill_section) added rs_machine_dependent case
10410 (write_object_file) call fixup_mdeps
10411 (fixup_segment) set fx_subsy to 0.
10412 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
10414 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
10417 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

10441 tc-i960.c (md_ri_to_chars): Always output bout object file in
10442 little endian byte order (used to use endianness of host).
10444 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10446 * config/tc-m68k.c (init_table): Now const. Always include 68851
10447 data, so that "bc" is available to 68040 cache instructions.
10448 Added "tt0", "tt1", and 68ec030 variants.
10449 (md_assemble): Complain if 68000 (only) and 68881 are specified.
10450 (enum _register): Added TT0, TT1.
10451 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
10452 line number correctly in "internal error" messages. Don't print
10453 architecture-mismatch message for operand errors.
10455 From Colin Smith (colin@wrs.com):
10456 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
10457 than install_operand.

10473 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
10474 so that we can assemble hand-written libgcc code.
10476 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10478 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
10479 has already been formatted (but may still contain %-characters).
10480 (as_bad): Likewise.
10482 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
10484 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
10485 written with indirection on the last two operands, which can be
10486 either data or address registers. Added a new operand type 'r'
10487 which accepts either register type. Added '(' to notend stuff in
10488 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

10599 (md_assemble): If no CPU has been set (even if FPU/PMMU
10600 characteristics have been), default to 68020. Don't need extra
10601 quotes around error string.

10749 * read.c, write.c: Change a series of ifdef/elif to
10750 ifdef/else/ifdef etc.
10752 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
10754 * symbols.c (fb_label_init): fix sizeof to memset.
10756 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
10758 * Makefile.in: install the man page.
10760 * Makefile.in: pass down MAKEINFO explicitly on info.
10762 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
10764 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10766 * flonum-const.c: renamed flonum-konst.c to stop dos name
10769 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
10771 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
10772 tc-m68k.h to te-sun3.h.
10774 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
10776 * configure.in: vxworks68 gets te-sun3.h.
10778 * expr.c: remove limitation that local_labels_dollar or
10779 local_labels_fb must be < 10.
10781 * symbols.c: remove local_labels_dollar, replace with a function
10782 interface for a sparse array. All users adjusted.
10784 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
10786 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10788 * doc/Makefile.in: commented out line for building as-all.texinfo.
10791 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
10793 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
10795 * Makefile.in: added check target.
10797 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10799 * Makefile.in: added tooldir and program_prefix.
10801 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
10803 * write.{c,h} (fix_new): Make these declarations consistent.
10805 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
10807 * Makefile.in (strerror.o): Add rule so that broken Sun make can
10810 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
10812 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
10814 * expr.c (operand): if can't work out what sort of operand it is,
10815 then look through FLT_CHARS for a hint.
10817 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
10819 * Makefile.in, configure.in: removed traces of namesubdir,
10820 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10821 copyrights to '92, changed some from Cygnus to FSF.
10823 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
10824 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10825 copyrights to '92, changed some from Cygnus to FSF.
10827 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10829 * expr.c: If an expression is single comma, then return with
10830 SEG_ABSENT rather than an error - since the sparc front end does
10831 really strange things with things like fbge,a
10833 * as.h: include bfd.h if using many sections
10834 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
10835 local labels didn't work.
10836 * listing.c (list_symbol_table): don't core dump when there's no
10838 * write.c, write.h: call fix_new with the right number of args on
10840 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
10843 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10845 * app.c: MRI compatibility - allow single quote to start a string.
10846 * as.c: fix typo recently introduced.
10847 * as.h : Don't include aout/reloc.h - it's not right for COFF!
10848 * expr.c: Much rewriting, to accomodate MRI syntax for
10849 expressions. Also easier to read now.
10850 * listing.c: Put back defuns
10851 * read.c: modified to accept MRI syntax, put back listing pseudo
10852 ops so that an assembler built with NO_LISTING ignores list ops
10854 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
10855 machine is a SPARC or a 29K.
10856 * config/obj-aout.c: added s_sect pseudo op
10857 * config/obj-coffbfd.c: lints, set the filehdr flags right and
10858 fill in the timestamp.
10859 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
10860 anymore, define all the relocs which the tc-<x> bit will use so we
10861 can translate from them to the coff types.
10862 * config/tc-a29k.c: reloc_type isn't ane enum any more
10863 * config/tc-m68k.c: Added NO_RELOC definition.
10865 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10867 * Makefile.in: put header files before C source for TAGS; remove
10868 references to non-existent syscalls.h.
10870 * read.c, write.c subsegs.c: back out the .bss changes.
10872 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
10874 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
10876 * a.out.h: removed.
10878 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
10880 * symbols.c (local_label_name): symbols now start with ^A.
10882 * read.c, subsegs.c, write.c obj-coff.c: added handling of
10883 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
10884 generate these sections. .align: will use NOP_OPCODE or 0
10885 for padding. This is just for being nice to the
10888 * expr.c (operand): changed to generate local label "\001L0"
10889 starting with a ^A so that it is recognized as a local label.
10891 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
10893 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
10894 i/o opcodes - inb, inw, outb and outw. string manipulation with
10895 att syntax - scmp, slod, smov, ssca, ssto.
10897 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
10898 to just after .file .
10900 In obj_crawl_symbol_chain() where it tries to put the external
10901 symbols apart, with the condition:
10902 (!S_IS_DEFINED(symbolP) &&
10903 !S_IS_DEBUG(symbolP) &&
10904 !SF_GET_STATICS(symbolP))
10905 it was moving too many symbols out. So I switch it back to the
10907 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
10909 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
10910 so that we don't use the F_RELFLG which make the linker complain
10911 that somebody has stripped the relocation info.
10913 Also, the AIX ld program require that the relocation table
10914 is sorted by r_vaddr like the standard ATT assembler does.
10916 [he also changed the sizeof(struct ...)'s into the coff
10917 style FOOSZ macros. I'm not sure this is right, but I can't
10918 remember why. xoxorich.]
10920 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
10922 * Makefile.in, configure.in, doc: use the doc. Build it, install
10925 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
10927 * read.c: white space and comments only.
10929 * configure.in: use the new atof-ns32.c for ns32k.
10931 * write.c: comment change only.
10933 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
10934 aren't yet integrated.
10936 * tc-i860.[hc]: blew off the dust. Something must still be done
10937 about conflicting relocation types.
10939 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
10942 * tc-i960.c, tc-sparc.c: white space and comments only.
10944 * tc-a29k.h: delete duplicate macro definition.
10946 * new file atof-ns32k.c copied from hack's last unreleased gas.
10948 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
10950 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
10953 * nearly everything. flush ChangeLog, package as gas-1.92.1.
10954 ChangeLog's prior to this are sketchy at best. I have logs.
10955 They just aren't ChangeLogs.
