378 expression-valued symbol, and calling fix_new_exp recursively.
379 (adjust_reloc_syms): If a fixup's symbol value is a sum of an

495 (md_longopts): Add EB and EL.
496 (md_parse_option): Handle -EB and -EL as separate options, rather
497 than as a single -E option with an argument.
499 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
501 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
502 involving global symbols too.
504 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
506 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
508 * configure.in: Test for remove, not delete. Fix cross-assembler
510 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
513 * read.c (pseudo_set, case O_symbol): If
514 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
515 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
516 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
518 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
520 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
521 many others): new macros; values obtained from "DSTRECRDS.SDL".
522 * config/obj-vms.h (various): use them.
523 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
524 representation (only enum bitfields can avoid being bitstrings).
525 (bitfield_suffix, setup_basic_type): new routines.
526 (VMS_typedef_parse): use them. Now recognize bitfields of all
527 integral types, not just type `int'. Caveat: the representation
528 used for bitfields still does not work for objects placed in
529 registers, and gcc's optimizer sometimes puts small structs there.
531 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
533 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
535 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
536 (tc_frob_label): define this to call vms_check_for_special_label,
537 and declare the latter.
538 * config/obj-vms.c (vax_g_doubles): declare this file-scope
540 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
541 (vms_check_for_special_label): new routine (tc_frob_label).
542 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
543 and `gcc2_compiled.' labels; they won't reach here any more.
544 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
545 double', use `vax_g_doubles' flag to select type of double.
546 (VMS_write_object_file) [traceback setup]: don't pass symbols
547 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
548 and TBT_Routine_End functions.
550 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
552 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
553 S_GET_VALUE() to avoid many repeated function calls.
554 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
555 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
556 gets requested. [All the HACK_DEC_C_STARTUP code appears to
557 be obsolete; gcc does it automatically for vms target. It's
558 also misnamed, because it is for the "VAX C" run-time library,
559 not the newer "DEC C" one which has much different startup code.]
560 {various}: use `S_SET_xxx(symbol,new_value)' rather than
561 `S_GET_xxx(symbol) = new_value'.

570 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
572 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
574 * expr.c (expr): Don't reduce the difference of two symbols in the
575 same frag if the symbols are not in normal sections.
577 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
578 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
579 (obj_attach_unwind_info): Do not define. Not needed anymore.
580 * config/tc-hppa.c: Delete whitespace at EOL.

582 (fix_new_hppa): Last arg is now a pointer to an int. Do not
583 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
584 fixups, store 32bits of unwind information in the fx_addnumber
586 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
587 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
588 pointer to 32 bits of unwind info.
589 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
590 pointer to the dummy symbol; set the addend field to fx_addnumber.
591 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
592 rather than &bfd_XXX_section.
594 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
596 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
597 value by one; discard adjustments previously being made. From
600 VMS- and Vax-related changes from Pat Rankin:
601 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
602 * vmsconf.sh: no longer have make-gas.com echo text about needing
603 to modify the gcc-vms driver when intending to use with gcc 1.x.
604 * as.c (parse_options): suppress 'v' from std_short_options and
605 eliminate VMS-specific conditional initialization;
606 [default case]: check for '-v' if md_parse_options doesn't recognize
608 [default case, #if VMS]: check for filename argument when '-v' seen;
610 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
611 for O_big literal operands (double floats and long long ints);
612 [VMS, md_shortopts]: add second colon after 'v';
613 (md_parse_options) [VMS, case 'v']: check for argument, so
614 caller can handle `-v' w/o arg.

666 * gdbinit.in: New file, created from old .gdbinit.
668 * aclocal.m4 (GAS_GDBINIT): Deleted.
669 * configure.in: Don't use it. Instead, generate .gdbinit from
670 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
671 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
672 to ensure that older versions of autoconf aren't used.

698 PIC implementation for i386-linux, based on code from Eric
699 Youngdale and Paul Kranenburg, with some work of my own:
701 * write.c (fixup_segment): Test TC_RELOC_RTSYM_LOC_FIXUP on fixup
702 before processing same-section pcrel relocations.

809 Update for autoconf beta 1.112:
810 * aclocal.m4 (GAS_CHECK_DECL_NEEDED, GAS_WORKING_ASSERT): New
812 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
813 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
814 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
815 message to try to ease confusion about autoconf's
816 "cross-compiling" message.
817 * acconfig.h (NEED_DECLARATION_MALLOC, NEED_DECLARATION_FREE,
818 NEED_DECLARATION_ERRNO): Renamed from NEED_*_DECLARATION.

863 using autoconf @-substitutions.
865 Wed Aug 31 17:43:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
867 * atof-generic.c: Deleted alloca handling here.
869 * Makefile.in (prefix, exec_prefix): Use @-subtitutions.
871 * aclocal.m4 (AC_OUTPUT_LINKS): Deleted redefinition, since
872 autoconf 1.109 has this fixed.
873 * configure.in: Don't change quote characters around AC_MSG_ERROR
874 invocation. Don't use AC_HEADER_STDC, since it requires running a

897 symbol is used as an offset into a CSECT that is not a TOC. These
898 types of loads are generated by gcc -mminimal-toc.

1564 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
1565 to put a common symbol in a set.

1610 * read.c (emit_expr): Use memset to zero out memory, rather than
1611 going through md_number_to_chars. This permits handling symbolic

1665 (control_regs): New pointer.
1666 (m68k_ip): Use control_regs instead of testing CPU every time.
1667 Use last_movec_reg too. In error messages, handle 68060, and
1668 print 68060 for mfloat, too.
1669 (m68k_init_after_args): Handle "68060". Use m68040up for making
1670 m68851 choice. Set control_regs.

2039 * config/tc-mips.c (append_insn): Permit branches to be switched
2040 with the preceding instruction even if .set nobopt has been seen.
2041 .set nobopt actually controls whether to bring up an instruction

2112 source files from other directories into objects in the current
2113 directory, and specify PSECT attributes explicitly to linker.
2114 Also added missing label.

2182 elf_tc_make_sections stuff. It was there to support PA braindamage
2183 which has been fixed, and in the case of elf_tc_make_sections is
2184 redundant with elf_tc_final_processing.
2186 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2204 don't spew remainder of input file in error message.
2205 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error

2266 to make it pcrel_offset.
2267 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to

2284 but it should eventually be converted to generate the insn itself
2285 and call emit_insn directly.

2287 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

2319 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2320 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2321 works). Do not permit -G with SVR4_PIC.
2322 (s_abicalls): Warn if -G was used, and force -G 0.
2323 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for

2373 bfd_set_symtab is called.
2374 (dump_section_relocs): Note whether a symbol is a section symbol
2376 (adjust_reloc_syms): For now, always supply an absolute symbol for
2377 fixups without symbols but not yet `done'. Use section_symbol to
2378 get the symbol, instead of going directly for abs_symbol.
2379 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2380 reloc is not a section symbol and is not in the symbol table.
2381 (set_symtab): New function, broken out from write_object_file.
2382 Counts symbol table instead of relying on an earlier count.
2383 (write_object_file): Call set_symtab, but do it after potentially
2384 invoking the *_frob_file macros. Don't bother counting symbols.
2385 Call symbol_remove, instead of expanding it in place. Moved the
2386 conditionalized `object_file_size' declaration down to
2387 conditionalized block where it's used. When using the absolute
2388 symbol for a fixup without a symbol, set sy_used_in_reloc.
2389 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2390 the correct symbol for the absolute section.
2392 * subsegs.c (section_symbol): Use symbol_new instead of
2393 symbol_make, since we may want it to go into the symbol table.
2394 Make the new symbol have internal linkage. If
2395 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2396 symbol with the newly created GAS symbol.

2405 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2406 (sparc_ip, label "immediate"): Reject constants for pcrel
2407 instructions only if the relocation type indicates a "call"
2408 instruction and the offset is within range of a "jmpl %g0". If
2409 it's not in range, use the absolute section symbol plus an offset.
2410 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2412 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2414 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2417 * configure.in: Eliminated all targets using obj-coff but not
2418 defining BFD_ASSEMBLER; I think all such targets that are
2419 supported will be matched by real CPU-OS combinations earlier in
2421 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2422 some comments about the dpx2 configuration, but left it disabled,
2423 since it couldn't be reached before.

2434 the 'j' operand if there are no further alternatives for this
2437 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2438 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2439 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2441 * config/tc-mips.c (mips_align): Take new argument, label, and use
2442 it instead of global insn_label.
2443 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2444 call to mips_emit_delay and pass it to mips_align.
2446 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2448 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.

2466 values to reduce number of lookups with S_GET_VALUE. Skip debug
2467 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2468 holger@botbso.rhein-main.de.)
2469 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2470 field. (Also from Holger Teutsch.) Watch for a would-be register
2471 mask that spans frags.
2473 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2474 this_base, not line_base. (Patch from Andreas Arens,

2478 look local if they're exported or undefined. Used to be done for
2481 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

2485 (lex_type): Use it for `%'.
2487 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

4220 descriptor information to the BFD symbol.
4221 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

4272 pass new argument for i, j and o cases.
4273 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

4494 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
4495 the table, require that the one without bit 0x1000000 set come

4606 OPTIONAL_REGISTER_PREFIX if either is already defined.
4608 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4610 * configure.in: Set bfd_gas for all sparc targets. Added facility
4611 for keeping or rejecting configurations still under development;
4612 default is to assume production environment, and reject configs
4613 still being worked on. Mark Elf configurations (except sparc and
4614 i386) as developmental. Deleted cases matching some generic names
4615 in favor of more specific names. (E.g., when we get Alpha
4616 support, we'll still only support VMS for Vax.)

4632 through inclusion of tc-hppa.h. Delete all forward declarations
4633 for functions only used within tc-hppa.c, likewise for structures,
4634 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4635 conditional code in a few small places.
4637 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4638 structures, global variables, forward declarations together.

4640 conditional code -- try to group conditional code together
4641 into a few places. Make all functions and variables which
4642 are only used within tc-hppa.c static. PARAMize all functions.
4643 Add comments to functions. Delete unused functions, variables,
4644 #defines, etc. Delete unused members within structures. Delete
4645 ldil;ble hacks -- it is believed they were installed to work
4646 around old gas bugs. Avoid using mixed case for local
4647 functions, variables, and structures. Fix formatting problems
4648 not found by GNU-indent. Add FIXME notices for things which
4649 should be worked on the near future. Delete lots of old
4650 useless (1.36 PA-SOM) code.
4652 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
4653 field of the fixS structure. Needed to build unwind

5812 * Extensive changes to permit symbols to contain any expression
5813 type and to delay the computation of the expression until the
5814 value is actually needed. This permits setting symbols to values
5815 calculated based on object code size. Expressions were changed to
5816 no longer be in a section, to stop the overloading of segment and
5817 expression type that previously occurred.
5819 * as.c (big_section, pass1_section, diff_section, absent_section):
5821 (expr_section): Added (used for dummy symbols which hold

5930 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
5931 calculating opP->isiz; this permits the expression size to be
5932 determined as well, later on.

5946 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
5948 * read.c (float_cons): Simplified parsing logic. If
5949 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.

7118 dependencies are read, not when they are used).
7120 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
7121 a29k .bss section; the mondfe program doesn't like it.

7142 source directory, if that's not the current directory.
7144 * configure.in (per-host): Accept MIPS host with BSD version

7165 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
7166 process relocs if there aren't any relocs to process. Avoids
7167 malloc/free bug on SCO too.

7170 avoid some redefinition complaints on some systems.
7171 (const, volatile): Don't need these conditionally defined if we
7172 use CONST and VOLATILE from ansidecl.h.
7173 (seg_name): Use CONST, not const.
7175 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
7177 * config/tc-mips.c: Reindented to GNU standards.
7179 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
7181 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
7182 (fixup_segment): Add a29k special case; the linker is not prepared
7183 to see a segment offset here.
7185 * app.c (do_scrub_next_char): Added new state, 10, modifying state
7186 9 to only keep a space in between identifier characters.
7188 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
7190 * Makefile.in: add dvi target; as-$(config).texinfo might live in
7191 srcdir, might be in objdir.
7193 * doc/Makefile.in: dvi depends on as.dvi

7211 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
7212 bignums, but don't emit error message.
7214 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
7216 * Makefile.in (targ-cpu.o): Depend on config.h.
7218 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
7220 * app.c (do_scrub_next_char): Added new state, 9, to avoid
7221 dropping a space immediately following an identifier.
7222 * expr.c, write.c: Rewrote assert expressions to not use multiple
7223 lines; I don't think that can be done portably.
7224 * config/tc-mips.c (macro): Use $AT if target register is zero in
7225 load instruction, which it can be for a floating point load.
7227 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

7235 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
7238 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
7239 z8k-opc.h, not z8k.h.
7241 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
7244 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
7246 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
7248 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
7250 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
7251 to be on a single line.

7295 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
7296 (struct loc, struct proc, struct file): Moved to tc-mips.c within
7297 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
7298 * config/tc-mips.c: Rearranged for ECOFF support. Added
7299 prototypes for all static functions. Moved existing minimal
7300 debugging format support info #ifndef OBJ_ECOFF blocks.
7301 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
7302 does not support a non sign extended high 16 bits reloc. Adjusted
7303 all callers accordingly.
7304 (tc_get_register): Renamed from get_register, and made non-static.

7349 * make-gas.com: Find obstack.obj if it's not in the current
7351 * read.c (s_ignore): Don't declare is_end_of_line. It's
7352 redundant, and triggers a VMS gcc compiler bug.
7354 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7355 current segment as an argument. (Ignored in all cases but VMS.)
7356 All callers and definitions changed.
7358 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
7360 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING

7375 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
7376 Call elf_xstabs for .stabs and .xstabs operators.
7378 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
7380 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
7383 * configure.in: mips-bsd configuration was missing format spec.
7386 * Makefile.in (Makefile): Depends on configure.in.
7388 * config/tc-mips.c (append_insn): Don't check for alignment of
7389 frag in memory; alignment of instructions in section is a separate

7409 * config/tc-sparc.c (s_xword): Now call big_cons, so large
7410 constants are accepted, but symbolic values are not. GCC will not
7411 generate the latter currently.
7413 * frags.c (frag_init): New function.
7414 (zero_address_frag, bss_address_frag): Now initialized at run
7416 * as.c (main): Call frag_init.

7446 "IGNORE_DEBUG" conditional, since both branches are identical.
7447 Use S_SET_TYPE, S_GET_TYPE, and S_GET_DESC instead of directly
7448 referencing symbol structure members.
7449 (obj_aout_frob_symbol) [BFD_ASSEMBLER]: New function.
7451 * as.h (struct frag): Reordered a couple of fields for better

7459 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
7460 (fixup_segment): Make sure common-section symbols get treated the
7461 same as undefined symbols.
7462 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type
7463 bfd_reloc_code_real_type. Use seg_fix_{root,tail}P derived from
7465 * write.h (fix_new): Update prototype.
7467 * tc.h (md_operand, md_convert_frag, tc_headers_hook,
7468 md_section_align, md_undefined_symbol): Don't provide prototypes
7469 if these are defined as macros.

7473 * symbols.c (symbol_new): Argument NAME is now pointer to const.
7474 Simplified STRIP_UNDERSCORE code. Remove assumptions about null
7475 pointers in freshly allocated storage. [BFD_ASSEMBLER]: Get new
7477 (colon): Display other/desc fields of redefined symbol only if

7668 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
7669 latter, instead of selecting with preprocessor conditionals.
7671 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
7673 * configure.in: recognise all sparclite variants
7675 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

7683 * expr.c (operand): If character other than comma or newline is a
7684 logical end-of-line character, use the newline case.
7685 From Eric Youngdale:
7686 (operand): Set X_add_number field for floating-point numbers.
7687 (operand): Treat zero byte as end-of-operand.
7689 * configure.in (per-target): Look for with_bfd_assembler option.
7690 For now, only accept "no", until the merge is done.
7692 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7693 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

7699 * expr.c: Add "const" modifier to hex_value.
7700 * symbols.c: Finish conversion to S_* macros in the VMS only
7701 parts of the program. Add "const" modifier to
7702 md_[long,short]_jump_size. Remove declaration of const_flag
7703 (which will be declared in obj-vms.h).
7704 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7705 Fix arguments to VMS_write_object_file.
7706 * config-gas.com: New file. Script for VMS systems to set up the
7707 configuration to build gas for VMS, and create config.status.
7708 * make-gas.com: Redone to work with new scheme.
7709 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
7711 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
7712 will swap bytes if needed on a big endian system. Use throughout
7714 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
7715 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7716 types of malformed stabs. Change parsing algorithm so that we are
7717 more certain of having all of the information that we need on hand.
7718 * obj-vms.c (final_forward_reference): New function, used to help
7719 resolve the data types of as many struct elements as possible
7720 when some part of the struct is not fully defined by the compiler.

7723 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7724 as symbols as well in the object file. Look for external functions

7726 g++ compiler is incapable of doing this.
7727 * tc-vax.c: Add '1' option for backward compatibility with older GCC
7729 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
7730 * input-scrub.c (as_where): Fix bug where as would crash if we did not
7731 have the name of the source file yet.
7732 * config/ho-vms.h: define HO_VMS, not HO_VAX.
7734 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
7736 * read.c (s_data): Always use "data_section", since it'll map to
7737 SEG_DATA or SEG_E1 if needed.
7738 (s_lcomm): Likewise with bss_section.
7739 (s_fill): Use memset, not bzero.
7741 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

7763 (big_section, reg_section, pass1_section, diff_section,
7764 absent_section, text_section, data_section, bss_section): If
7765 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
7766 mapping to segT enum values.
7767 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7768 if these are used or defined, if BFD_ASSEMBLER.
7769 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7770 subseg_new split into two functions.
7771 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7773 * as.h (volatile): Don't define if already defined.
7774 (had_errors, had_warnings): Provide prototypes for ANSI C even if
7776 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7777 declare with format attribute for -Wformat checking.
7779 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7781 * app.c, config/tc-*.c: Don't include read.h, since it is already
7784 * These are based on patches from Minh Tran-le
7785 <mtranle@paris.intellicorp.com>.
7786 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7787 obj_format coffbfd and gas_target i386coff for target.
7788 (i[34]86-*-isc*): New host (uses sysv).
7789 * config/i386aix.mt: Removed (no longer used).
7790 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7792 (LDFLAGS): Added, defined as -shlib.
7793 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7794 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7795 (DOT_LABEL_PREFIX): Define.
7796 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7797 name rather than L0\001.

7809 (size_section): Restored sanity check.
7810 (do_relocs_for): Base section address on s_paddr rather than
7811 computing it. Adjust a29k R_IHIHALF special case to account for
7812 section paddr (used to require paddr to be zero). If there are no
7813 reclos, set s_relptr to 0. Set relocation size in object_headers.
7814 (fill_section): Always set s_vaddr here, removing
7815 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7816 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7817 Set STYP_INFO for .comment.
7818 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7819 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

7821 H_{SET,GET}_* macros.
7822 (do_linenos_for): Set lineno size in object_headers.
7823 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7824 set s_vaddr here. If string_byte_count remains 4, set it back to
7825 0, and only write strings out if there are some. Call
7826 fill_section before do_relocs_for and do_linenos_for.
7827 (obj_coff_section): Handle optional quoted second argument giving
7828 section characteristics.
7829 (obj_coff_bss): Added to handle .bss.
7830 (obj_coff_ident): Added to handle .ident (puts string in .comment

7850 (do_scrub_next_char): For \", return " not '.
7851 (symbol_chars): Now const.
7853 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7854 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7856 * config/obj-coff.h: Don't use #elif.
7858 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7859 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
7861 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
7863 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

7877 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
7879 * listing.c: Call xmalloc, not malloc; don't declare malloc.
7881 * Changes to support SCO 3.2v4:

7883 SEG_BSS, fill with NOP_OPCODE.
7884 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
7885 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
7886 using ZERO_BASED_SEGMENTS.
7887 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7888 never set segment address for SEG_E2 (.bss) and don't write out
7889 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7890 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7891 definitions, and don't merge tags with non-tags. Check for .bf
7892 rather than just checking whether the second character is b and
7893 the third character is f.
7894 (obj_coff_val): gcc can generate values which we don't handle
7895 correctly; discard information for now, since it only affects the
7896 debugging information.
7897 (tag_find_or_name): Don't insert tags in the symbol table.
7898 (yank_symbols): Don't merge labels.
7899 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7916 Mon Dec 7 00:39:09 1992 Ken Raeburn (raeburn@cygnus.com)
7918 * config/tc-i386.c (md_pseudo_table): For 386bsd and linux, do
7919 power-of-two alignment for .align.
7921 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
7922 and leave everything else alone.

8045 could be doing emulation.
8047 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8050 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

8081 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8082 constant will not fit in an immediate field.
8083 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

8120 * Support for i386-sysv.
8121 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8161 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8163 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8164 #elif, since it is not supported by old compilers.
8165 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8166 couple of expressions in tc-m68k.c.
8168 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8170 * read.c (cons): If NO_RELOC is defined, use it.
8172 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8174 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8176 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8177 local labels to start with a .) and set REGISTER_PREFIX to %.
8178 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8180 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

8194 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8196 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8197 sections starting from zero, rather than making them consecutive.
8198 This makes subsequent reloc calculations easier, esp if the object
8199 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8200 allocate lcomm in .data rather than in .bss. It seems that some
8201 tools can't cope with a non-zero sized bss before linkage.
8203 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8205 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

8224 * Makefile.in (install): if $(tooldir) exists, install as in
8227 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8229 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8230 .word is < -32768 or > 32767. The -J flag causes the error to be
8231 ignored. This is to catch over-sized switches generated by gcc on
8232 systems which don't support the broken .word hack.
8233 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8234 write.c (fixup_segment): check for signed .word overflow if
8235 WARN_SIGNED_OVERFLOW_WORD.
8237 * write.c (fixup_segment): fixed missing parens in expression
8238 checking for byte or word overflow.

8254 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8256 * input-scrub.c (input_scrub_push): call input_file_begin, not
8258 messages.c (as_perror): print ": " between the passed in error and
8259 the strerror, like perror does.

8264 From Steve Chamberlain:
8265 Makefile.in: Handle m68*-*-coff*.
8266 read.c, read.h: add mult argument to s_space
8268 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8269 Motorola and MIT syntax; gas can now assemble either type of
8271 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

8278 (fixup_segment) set fx_subsy to 0.
8279 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8281 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8284 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8286 * Makefile.in (LIBS): Include opcode library.
8288 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

8308 tc-i960.c (md_ri_to_chars): Always output bout object file in
8309 little endian byte order (used to use endianness of host).
8311 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8313 * config/tc-m68k.c (init_table): Now const. Always include 68851
8314 data, so that "bc" is available to 68040 cache instructions.
8315 Added "tt0", "tt1", and 68ec030 variants.
8316 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8317 (enum _register): Added TT0, TT1.
8318 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
8319 line number correctly in "internal error" messages. Don't print
8320 architecture-mismatch message for operand errors.
8322 From Colin Smith (colin@wrs.com):
8323 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
8324 than install_operand.

8338 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
8340 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
8341 so that we can assemble hand-written libgcc code.

8345 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8346 has already been formatted (but may still contain %-characters).
8349 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8351 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8352 written with indirection on the last two operands, which can be
8353 either data or address registers. Added a new operand type 'r'
8354 which accepts either register type. Added '(' to notend stuff in
8355 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
8357 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

8370 defined, call it. Change segments before calling fixup_segment.
8371 (relax_align): If linkrelax, provide extra padding.
8373 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
8374 their not having symbols associated.
8376 * tc-i960.c (norelax, instrument_branches): Default initializer is
8378 (linkrelax): Delete variable definition.

8402 being used with args swapped, causing occasional lossage when
8403 refilling buffers after an include file.
8405 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
8407 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
8408 version. Discard bogus DONTDEF version.
8409 (as_warn, as_bad, as_fatal): Likewise.
8411 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
8413 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
8414 selected architecture, print a message saying so and listing what
8415 processors support it, rather than saying "operands mismatch".

8467 characteristics have been), default to 68020. Don't need extra
8468 quotes around error string.

8550 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
8552 * write.c (write_object_file): keep the fix_tail clean, which
8553 fixes a bug in -R where relocations were being lost.
8555 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
8557 * configure.in: recognize m680x0 as having sun3 emulation mode for

8602 start addresses to match required alignment.
8604 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8606 * Makefile.in (install): Install into $(tooldir)/bin, since that's
8607 where gcc looks for it.
8609 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
8611 * Makefile.in: Changed some lines to be less confusing for some

8677 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
8679 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
8681 * expr.c (operand): if can't work out what sort of operand it is,
8682 then look through FLT_CHARS for a hint.
8684 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
8686 * Makefile.in, configure.in: removed traces of namesubdir,
8687 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8688 copyrights to '92, changed some from Cygnus to FSF.
8690 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
8691 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8692 copyrights to '92, changed some from Cygnus to FSF.
8694 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8696 * expr.c: If an expression is single comma, then return with
8697 SEG_ABSENT rather than an error - since the sparc front end does
8698 really strange things with things like fbge,a
8700 * as.h: include bfd.h if using many sections
8701 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8702 local labels didn't work.
8703 * listing.c (list_symbol_table): don't core dump when there's no
8705 * write.c, write.h: call fix_new with the right number of args on
8707 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8710 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8712 * app.c: MRI compatibility - allow single quote to start a string.
8713 * as.c: fix typo recently introduced.
8714 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8715 * expr.c: Much rewriting, to accomodate MRI syntax for
8716 expressions. Also easier to read now.
8717 * listing.c: Put back defuns
8718 * read.c: modified to accept MRI syntax, put back listing pseudo
8719 ops so that an assembler built with NO_LISTING ignores list ops
8721 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8722 machine is a SPARC or a 29K.
8723 * config/obj-aout.c: added s_sect pseudo op
8724 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8725 fill in the timestamp.
8726 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8727 anymore, define all the relocs which the tc-<x> bit will use so we
8728 can translate from them to the coff types.
8729 * config/tc-a29k.c: reloc_type isn't ane enum any more
8730 * config/tc-m68k.c: Added NO_RELOC definition.
8732 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8734 * Makefile.in: put header files before C source for TAGS; remove
8735 references to non-existent syscalls.h.
8737 * read.c, write.c subsegs.c: back out the .bss changes.
8739 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8741 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8745 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8747 * symbols.c (local_label_name): symbols now start with ^A.
8749 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8750 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8751 generate these sections. .align: will use NOP_OPCODE or 0
8752 for padding. This is just for being nice to the
8755 * expr.c (operand): changed to generate local label "\001L0"
8756 starting with a ^A so that it is recognized as a local label.
8758 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8760 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8761 i/o opcodes - inb, inw, outb and outw. string manipulation with
8762 att syntax - scmp, slod, smov, ssca, ssto.
8764 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8765 to just after .file .
8767 In obj_crawl_symbol_chain() where it tries to put the external
8768 symbols apart, with the condition:
8769 (!S_IS_DEFINED(symbolP) &&
8770 !S_IS_DEBUG(symbolP) &&
8771 !SF_GET_STATICS(symbolP))
8772 it was moving too many symbols out. So I switch it back to the
8774 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8776 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8777 so that we don't use the F_RELFLG which make the linker complain
8778 that somebody has stripped the relocation info.
8780 Also, the AIX ld program require that the relocation table
8781 is sorted by r_vaddr like the standard ATT assembler does.
8783 [he also changed the sizeof(struct ...)'s into the coff
8784 style FOOSZ macros. I'm not sure this is right, but I can't
8785 remember why. xoxorich.]
8787 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
8789 * Makefile.in, configure.in, doc: use the doc. Build it, install

8794 * read.c: white space and comments only.
8796 * configure.in: use the new atof-ns32.c for ns32k.
8798 * write.c: comment change only.
8800 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8801 aren't yet integrated.
8803 * tc-i860.[hc]: blew off the dust. Something must still be done
8804 about conflicting relocation types.
8806 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8809 * tc-i960.c, tc-sparc.c: white space and comments only.
8811 * tc-a29k.h: delete duplicate macro definition.
8813 * new file atof-ns32k.c copied from hack's last unreleased gas.
8815 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8817 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8820 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8821 ChangeLog's prior to this are sketchy at best. I have logs.
8822 They just aren't ChangeLogs.
8829 version-control: never
