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

496 special 4600 handling; it turns out not to be required.
498 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
500 * config/tc-mips.c (md_shortopts): Remove E.
501 (md_longopts): Add EB and EL.
502 (md_parse_option): Handle -EB and -EL as separate options, rather
503 than as a single -E option with an argument.
505 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
507 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
508 involving global symbols too.
510 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
512 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
514 * configure.in: Test for remove, not delete. Fix cross-assembler
516 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
519 * read.c (pseudo_set, case O_symbol): If
520 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
521 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
522 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
524 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
526 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
527 many others): new macros; values obtained from "DSTRECRDS.SDL".
528 * config/obj-vms.h (various): use them.
529 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
530 representation (only enum bitfields can avoid being bitstrings).
531 (bitfield_suffix, setup_basic_type): new routines.
532 (VMS_typedef_parse): use them. Now recognize bitfields of all
533 integral types, not just type `int'. Caveat: the representation
534 used for bitfields still does not work for objects placed in
535 registers, and gcc's optimizer sometimes puts small structs there.
537 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
539 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
541 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
542 (tc_frob_label): define this to call vms_check_for_special_label,
543 and declare the latter.
544 * config/obj-vms.c (vax_g_doubles): declare this file-scope
546 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
547 (vms_check_for_special_label): new routine (tc_frob_label).
548 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
549 and `gcc2_compiled.' labels; they won't reach here any more.
550 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
551 double', use `vax_g_doubles' flag to select type of double.
552 (VMS_write_object_file) [traceback setup]: don't pass symbols
553 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
554 and TBT_Routine_End functions.
556 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
558 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
559 S_GET_VALUE() to avoid many repeated function calls.
560 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
561 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
562 gets requested. [All the HACK_DEC_C_STARTUP code appears to
563 be obsolete; gcc does it automatically for vms target. It's
564 also misnamed, because it is for the "VAX C" run-time library,
565 not the newer "DEC C" one which has much different startup code.]
566 {various}: use `S_SET_xxx(symbol,new_value)' rather than
567 `S_GET_xxx(symbol) = new_value'.

576 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
578 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
580 * expr.c (expr): Don't reduce the difference of two symbols in the
581 same frag if the symbols are not in normal sections.
583 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
584 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
585 (obj_attach_unwind_info): Do not define. Not needed anymore.
586 * config/tc-hppa.c: Delete whitespace at EOL.
587 (struct hppa_fix_struct): Delete fx_unwind field and all references.
588 (fix_new_hppa): Last arg is now a pointer to an int. Do not
589 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
590 fixups, store 32bits of unwind information in the fx_addnumber
592 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
593 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
594 pointer to 32 bits of unwind info.
595 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
596 pointer to the dummy symbol; set the addend field to fx_addnumber.
597 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
598 rather than &bfd_XXX_section.
600 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
602 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
603 value by one; discard adjustments previously being made. From
606 VMS- and Vax-related changes from Pat Rankin:
607 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
608 * vmsconf.sh: no longer have make-gas.com echo text about needing
609 to modify the gcc-vms driver when intending to use with gcc 1.x.
610 * as.c (parse_options): suppress 'v' from std_short_options and
611 eliminate VMS-specific conditional initialization;
612 [default case]: check for '-v' if md_parse_options doesn't recognize
614 [default case, #if VMS]: check for filename argument when '-v' seen;
616 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
617 for O_big literal operands (double floats and long long ints);
618 [VMS, md_shortopts]: add second colon after 'v';
619 (md_parse_options) [VMS, case 'v']: check for argument, so
620 caller can handle `-v' w/o arg.

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

704 PIC implementation for i386-linux, based on code from Eric
705 Youngdale and Paul Kranenburg, with some work of my own:
707 * write.c (fixup_segment): Test TC_RELOC_RTSYM_LOC_FIXUP on fixup

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

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

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

1570 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
1571 to put a common symbol in a set.

1616 * read.c (emit_expr): Use memset to zero out memory, rather than
1617 going through md_number_to_chars. This permits handling symbolic

1671 (control_regs): New pointer.
1672 (m68k_ip): Use control_regs instead of testing CPU every time.

1674 print 68060 for mfloat, too.
1675 (m68k_init_after_args): Handle "68060". Use m68040up for making
1676 m68851 choice. Set control_regs.

2045 * config/tc-mips.c (append_insn): Permit branches to be switched
2046 with the preceding instruction even if .set nobopt has been seen.
2047 .set nobopt actually controls whether to bring up an instruction

2188 elf_tc_make_sections stuff. It was there to support PA braindamage
2189 which has been fixed, and in the case of elf_tc_make_sections is
2190 redundant with elf_tc_final_processing.

2290 but it should eventually be converted to generate the insn itself
2291 and call emit_insn directly.

2293 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

2326 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2327 works). Do not permit -G with SVR4_PIC.
2328 (s_abicalls): Warn if -G was used, and force -G 0.
2329 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for

2379 bfd_set_symtab is called.
2380 (dump_section_relocs): Note whether a symbol is a section symbol
2382 (adjust_reloc_syms): For now, always supply an absolute symbol for
2383 fixups without symbols but not yet `done'. Use section_symbol to
2384 get the symbol, instead of going directly for abs_symbol.
2385 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2386 reloc is not a section symbol and is not in the symbol table.
2387 (set_symtab): New function, broken out from write_object_file.
2388 Counts symbol table instead of relying on an earlier count.
2389 (write_object_file): Call set_symtab, but do it after potentially
2390 invoking the *_frob_file macros. Don't bother counting symbols.
2391 Call symbol_remove, instead of expanding it in place. Moved the
2392 conditionalized `object_file_size' declaration down to
2393 conditionalized block where it's used. When using the absolute
2394 symbol for a fixup without a symbol, set sy_used_in_reloc.
2395 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2396 the correct symbol for the absolute section.
2398 * subsegs.c (section_symbol): Use symbol_new instead of
2399 symbol_make, since we may want it to go into the symbol table.
2400 Make the new symbol have internal linkage. If
2401 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2402 symbol with the newly created GAS symbol.
2403 (obj_sec_sym_ok_for_reloc): Default to always returning 0.

2411 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2412 (sparc_ip, label "immediate"): Reject constants for pcrel
2413 instructions only if the relocation type indicates a "call"
2414 instruction and the offset is within range of a "jmpl %g0". If
2415 it's not in range, use the absolute section symbol plus an offset.
2416 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2418 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2420 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2423 * configure.in: Eliminated all targets using obj-coff but not
2424 defining BFD_ASSEMBLER; I think all such targets that are
2425 supported will be matched by real CPU-OS combinations earlier in
2427 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2428 some comments about the dpx2 configuration, but left it disabled,
2429 since it couldn't be reached before.
2430 (target a29k-amd-ebmonold): Deleted.

2440 the 'j' operand if there are no further alternatives for this
2443 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2444 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2445 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2447 * config/tc-mips.c (mips_align): Take new argument, label, and use
2448 it instead of global insn_label.
2449 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2450 call to mips_emit_delay and pass it to mips_align.
2452 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2454 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2456 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2457 argument to a .callinfo directive. Don't loop forever on errors.

2464 * write.c (write_object_file): Check both S_IS_LOCAL and
2465 S_IS_EXTERNAL when deciding whether to discard a symbol.
2467 * config-gas.com: Scan Makefile.in, not version.c, for current
2468 version number. Delete all versions of temp files when finished
2469 with them. Create config.h.

2472 values to reduce number of lookups with S_GET_VALUE. Skip debug
2473 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2474 holger@botbso.rhein-main.de.)
2475 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2476 field. (Also from Holger Teutsch.) Watch for a would-be register
2477 mask that spans frags.
2479 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2480 this_base, not line_base. (Patch from Andreas Arens,

2484 look local if they're exported or undefined. Used to be done for
2487 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

2491 (lex_type): Use it for `%'.
2493 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

4226 descriptor information to the BFD symbol.
4227 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

4246 an example of marker relocations.
4247 * write.c (write_relocs): Instead of assuming size of a relocation
4248 is 4 bytes, pick up the size from relocation itself.

4278 pass new argument for i, j and o cases.
4279 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

4282 rather than hard coded constants.
4283 (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and

4500 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
4501 the table, require that the one without bit 0x1000000 set come

4614 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4616 * configure.in: Set bfd_gas for all sparc targets. Added facility
4617 for keeping or rejecting configurations still under development;
4618 default is to assume production environment, and reject configs
4619 still being worked on. Mark Elf configurations (except sparc and
4620 i386) as developmental. Deleted cases matching some generic names
4621 in favor of more specific names. (E.g., when we get Alpha
4622 support, we'll still only support VMS for Vax.)

4638 through inclusion of tc-hppa.h. Delete all forward declarations
4639 for functions only used within tc-hppa.c, likewise for structures,
4640 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4641 conditional code in a few small places.
4643 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4644 structures, global variables, forward declarations together.

4646 conditional code -- try to group conditional code together
4647 into a few places. Make all functions and variables which
4648 are only used within tc-hppa.c static. PARAMize all functions.
4649 Add comments to functions. Delete unused functions, variables,
4650 #defines, etc. Delete unused members within structures. Delete
4651 ldil;ble hacks -- it is believed they were installed to work
4652 around old gas bugs. Avoid using mixed case for local
4653 functions, variables, and structures. Fix formatting problems
4654 not found by GNU-indent. Add FIXME notices for things which
4655 should be worked on the near future. Delete lots of old
4656 useless (1.36 PA-SOM) code.

5818 * Extensive changes to permit symbols to contain any expression
5819 type and to delay the computation of the expression until the
5820 value is actually needed. This permits setting symbols to values
5821 calculated based on object code size. Expressions were changed to
5822 no longer be in a section, to stop the overloading of segment and
5823 expression type that previously occurred.
5825 * as.c (big_section, pass1_section, diff_section, absent_section):
5827 (expr_section): Added (used for dummy symbols which hold

5936 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
5937 calculating opP->isiz; this permits the expression size to be
5938 determined as well, later on.

5952 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
5954 * read.c (float_cons): Simplified parsing logic. If
5955 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.

7062 than ECOFF line number information.
7063 (obj_ecoff_stab): Accept non-zero values for stabs line number.

7124 dependencies are read, not when they are used).
7126 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
7127 a29k .bss section; the mondfe program doesn't like it.

7148 source directory, if that's not the current directory.
7150 * configure.in (per-host): Accept MIPS host with BSD version

7171 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
7172 process relocs if there aren't any relocs to process. Avoids
7173 malloc/free bug on SCO too.

7176 avoid some redefinition complaints on some systems.
7177 (const, volatile): Don't need these conditionally defined if we
7178 use CONST and VOLATILE from ansidecl.h.
7179 (seg_name): Use CONST, not const.
7181 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
7183 * config/tc-mips.c: Reindented to GNU standards.
7185 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
7187 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
7188 (fixup_segment): Add a29k special case; the linker is not prepared
7189 to see a segment offset here.
7191 * app.c (do_scrub_next_char): Added new state, 10, modifying state
7192 9 to only keep a space in between identifier characters.
7194 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
7196 * Makefile.in: add dvi target; as-$(config).texinfo might live in
7197 srcdir, might be in objdir.
7199 * doc/Makefile.in: dvi depends on as.dvi

7217 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
7218 bignums, but don't emit error message.
7220 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
7222 * Makefile.in (targ-cpu.o): Depend on config.h.
7224 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
7226 * app.c (do_scrub_next_char): Added new state, 9, to avoid
7227 dropping a space immediately following an identifier.
7228 * expr.c, write.c: Rewrote assert expressions to not use multiple
7229 lines; I don't think that can be done portably.
7230 * config/tc-mips.c (macro): Use $AT if target register is zero in
7231 load instruction, which it can be for a floating point load.
7233 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

7241 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
7244 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
7245 z8k-opc.h, not z8k.h.
7247 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
7250 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
7252 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
7254 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
7256 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
7257 to be on a single line.

7301 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
7302 (struct loc, struct proc, struct file): Moved to tc-mips.c within
7303 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
7304 * config/tc-mips.c: Rearranged for ECOFF support. Added
7305 prototypes for all static functions. Moved existing minimal
7306 debugging format support info #ifndef OBJ_ECOFF blocks.
7307 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
7308 does not support a non sign extended high 16 bits reloc. Adjusted
7309 all callers accordingly.
7310 (tc_get_register): Renamed from get_register, and made non-static.
7312 * config/mips-big.mt, config/mips-lit.mt: New files. Define

7355 * make-gas.com: Find obstack.obj if it's not in the current
7357 * read.c (s_ignore): Don't declare is_end_of_line. It's
7358 redundant, and triggers a VMS gcc compiler bug.
7360 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7361 current segment as an argument. (Ignored in all cases but VMS.)
7362 All callers and definitions changed.

7380 argument to s_ignore. Put "#if 0" around unused code.
7381 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
7382 Call elf_xstabs for .stabs and .xstabs operators.
7384 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
7386 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
7389 * configure.in: mips-bsd configuration was missing format spec.
7392 * Makefile.in (Makefile): Depends on configure.in.
7394 * config/tc-mips.c (append_insn): Don't check for alignment of
7395 frag in memory; alignment of instructions in section is a separate

7415 * config/tc-sparc.c (s_xword): Now call big_cons, so large
7416 constants are accepted, but symbolic values are not. GCC will not
7417 generate the latter currently.
7419 * frags.c (frag_init): New function.
7420 (zero_address_frag, bss_address_frag): Now initialized at run
7422 * as.c (main): Call frag_init.

7454 referencing symbol structure members.
7455 (obj_aout_frob_symbol) [BFD_ASSEMBLER]: New function.
7457 * as.h (struct frag): Reordered a couple of fields for better

7465 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
7466 (fixup_segment): Make sure common-section symbols get treated the
7467 same as undefined symbols.
7468 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type
7469 bfd_reloc_code_real_type. Use seg_fix_{root,tail}P derived from
7471 * write.h (fix_new): Update prototype.
7473 * tc.h (md_operand, md_convert_frag, tc_headers_hook,
7474 md_section_align, md_undefined_symbol): Don't provide prototypes

7479 * symbols.c (symbol_new): Argument NAME is now pointer to const.
7480 Simplified STRIP_UNDERSCORE code. Remove assumptions about null
7481 pointers in freshly allocated storage. [BFD_ASSEMBLER]: Get new
7483 (colon): Display other/desc fields of redefined symbol only if

7675 latter, instead of selecting with preprocessor conditionals.
7677 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
7679 * configure.in: recognise all sparclite variants

7689 * expr.c (operand): If character other than comma or newline is a
7690 logical end-of-line character, use the newline case.
7691 From Eric Youngdale:
7692 (operand): Set X_add_number field for floating-point numbers.
7693 (operand): Treat zero byte as end-of-operand.
7695 * configure.in (per-target): Look for with_bfd_assembler option.
7696 For now, only accept "no", until the merge is done.
7698 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7699 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

7705 * expr.c: Add "const" modifier to hex_value.
7706 * symbols.c: Finish conversion to S_* macros in the VMS only
7707 parts of the program. Add "const" modifier to
7708 md_[long,short]_jump_size. Remove declaration of const_flag
7709 (which will be declared in obj-vms.h).
7710 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7711 Fix arguments to VMS_write_object_file.
7712 * config-gas.com: New file. Script for VMS systems to set up the
7713 configuration to build gas for VMS, and create config.status.
7714 * make-gas.com: Redone to work with new scheme.
7715 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
7717 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

7720 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
7721 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7722 types of malformed stabs. Change parsing algorithm so that we are
7723 more certain of having all of the information that we need on hand.
7724 * obj-vms.c (final_forward_reference): New function, used to help
7725 resolve the data types of as many struct elements as possible
7726 when some part of the struct is not fully defined by the compiler.

7729 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7730 as symbols as well in the object file. Look for external functions

7733 * tc-vax.c: Add '1' option for backward compatibility with older GCC
7735 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
7736 * input-scrub.c (as_where): Fix bug where as would crash if we did not
7737 have the name of the source file yet.
7738 * config/ho-vms.h: define HO_VMS, not HO_VAX.
7740 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
7742 * read.c (s_data): Always use "data_section", since it'll map to
7743 SEG_DATA or SEG_E1 if needed.
7744 (s_lcomm): Likewise with bss_section.
7745 (s_fill): Use memset, not bzero.
7747 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

7769 (big_section, reg_section, pass1_section, diff_section,
7770 absent_section, text_section, data_section, bss_section): If
7771 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
7772 mapping to segT enum values.
7773 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7774 if these are used or defined, if BFD_ASSEMBLER.
7775 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7776 subseg_new split into two functions.
7777 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7779 * as.h (volatile): Don't define if already defined.
7780 (had_errors, had_warnings): Provide prototypes for ANSI C even if
7782 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7783 declare with format attribute for -Wformat checking.
7785 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7787 * app.c, config/tc-*.c: Don't include read.h, since it is already
7790 * These are based on patches from Minh Tran-le
7791 <mtranle@paris.intellicorp.com>.
7792 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7793 obj_format coffbfd and gas_target i386coff for target.
7794 (i[34]86-*-isc*): New host (uses sysv).
7795 * config/i386aix.mt: Removed (no longer used).
7796 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7798 (LDFLAGS): Added, defined as -shlib.
7799 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7800 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7801 (DOT_LABEL_PREFIX): Define.

7815 (size_section): Restored sanity check.
7816 (do_relocs_for): Base section address on s_paddr rather than
7817 computing it. Adjust a29k R_IHIHALF special case to account for
7818 section paddr (used to require paddr to be zero). If there are no
7819 reclos, set s_relptr to 0. Set relocation size in object_headers.
7820 (fill_section): Always set s_vaddr here, removing
7821 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7822 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7823 Set STYP_INFO for .comment.
7824 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7825 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

7827 H_{SET,GET}_* macros.
7828 (do_linenos_for): Set lineno size in object_headers.
7829 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7830 set s_vaddr here. If string_byte_count remains 4, set it back to
7831 0, and only write strings out if there are some. Call
7832 fill_section before do_relocs_for and do_linenos_for.
7833 (obj_coff_section): Handle optional quoted second argument giving
7834 section characteristics.
7835 (obj_coff_bss): Added to handle .bss.
7836 (obj_coff_ident): Added to handle .ident (puts string in .comment

7856 (do_scrub_next_char): For \", return " not '.
7857 (symbol_chars): Now const.
7859 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7860 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7862 * config/obj-coff.h: Don't use #elif.
7864 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7865 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
7867 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
7869 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

7889 SEG_BSS, fill with NOP_OPCODE.
7890 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
7891 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
7892 using ZERO_BASED_SEGMENTS.
7893 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7894 never set segment address for SEG_E2 (.bss) and don't write out
7895 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7896 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7897 definitions, and don't merge tags with non-tags. Check for .bf
7898 rather than just checking whether the second character is b and
7899 the third character is f.
7900 (obj_coff_val): gcc can generate values which we don't handle
7901 correctly; discard information for now, since it only affects the
7902 debugging information.
7903 (tag_find_or_name): Don't insert tags in the symbol table.
7904 (yank_symbols): Don't merge labels.
7905 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7924 * config/tc-i386.c (md_pseudo_table): For 386bsd and linux, do
7925 power-of-two alignment for .align.
7927 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
7928 and leave everything else alone.

8051 could be doing emulation.
8053 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8056 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

8087 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8088 constant will not fit in an immediate field.
8089 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

8126 * Support for i386-sysv.
8127 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8167 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8169 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8170 #elif, since it is not supported by old compilers.
8171 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8172 couple of expressions in tc-m68k.c.
8174 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8176 * read.c (cons): If NO_RELOC is defined, use it.
8178 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8180 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8182 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8183 local labels to start with a .) and set REGISTER_PREFIX to %.
8184 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8186 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

8200 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8202 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8203 sections starting from zero, rather than making them consecutive.
8204 This makes subsequent reloc calculations easier, esp if the object
8205 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8206 allocate lcomm in .data rather than in .bss. It seems that some
8207 tools can't cope with a non-zero sized bss before linkage.
8209 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8211 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

8230 * Makefile.in (install): if $(tooldir) exists, install as in
8233 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8235 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8236 .word is < -32768 or > 32767. The -J flag causes the error to be
8237 ignored. This is to catch over-sized switches generated by gcc on
8238 systems which don't support the broken .word hack.
8239 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8240 write.c (fixup_segment): check for signed .word overflow if
8241 WARN_SIGNED_OVERFLOW_WORD.
8243 * write.c (fixup_segment): fixed missing parens in expression
8244 checking for byte or word overflow.

8260 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8262 * input-scrub.c (input_scrub_push): call input_file_begin, not
8264 messages.c (as_perror): print ": " between the passed in error and
8265 the strerror, like perror does.
8267 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

8270 From Steve Chamberlain:
8271 Makefile.in: Handle m68*-*-coff*.
8272 read.c, read.h: add mult argument to s_space
8274 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8275 Motorola and MIT syntax; gas can now assemble either type of
8277 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

8284 (fixup_segment) set fx_subsy to 0.
8285 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8287 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8290 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8292 * Makefile.in (LIBS): Include opcode library.
8294 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

8314 tc-i960.c (md_ri_to_chars): Always output bout object file in
8315 little endian byte order (used to use endianness of host).
8317 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8319 * config/tc-m68k.c (init_table): Now const. Always include 68851
8320 data, so that "bc" is available to 68040 cache instructions.
8321 Added "tt0", "tt1", and 68ec030 variants.
8322 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8323 (enum _register): Added TT0, TT1.
8324 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
8325 line number correctly in "internal error" messages. Don't print
8326 architecture-mismatch message for operand errors.
8328 From Colin Smith (colin@wrs.com):
8329 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
8330 than install_operand.

8334 * listing.c (buffer_line): rewind to the start of include
8335 files, they might be included twice.

8344 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
8346 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
8347 so that we can assemble hand-written libgcc code.

8351 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8352 has already been formatted (but may still contain %-characters).
8355 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8357 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8358 written with indirection on the last two operands, which can be
8359 either data or address registers. Added a new operand type 'r'
8360 which accepts either register type. Added '(' to notend stuff in
8361 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
8363 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

8376 defined, call it. Change segments before calling fixup_segment.
8377 (relax_align): If linkrelax, provide extra padding.
8379 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
8380 their not having symbols associated.
8382 * tc-i960.c (norelax, instrument_branches): Default initializer is
8384 (linkrelax): Delete variable definition.

8408 being used with args swapped, causing occasional lossage when
8409 refilling buffers after an include file.
8411 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
8413 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
8414 version. Discard bogus DONTDEF version.
8415 (as_warn, as_bad, as_fatal): Likewise.
8417 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
8419 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
8420 selected architecture, print a message saying so and listing what
8421 processors support it, rather than saying "operands mismatch".

8472 (md_assemble): If no CPU has been set (even if FPU/PMMU
8473 characteristics have been), default to 68020. Don't need extra
8474 quotes around error string.

8558 * write.c (write_object_file): keep the fix_tail clean, which
8559 fixes a bug in -R where relocations were being lost.
8561 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
8563 * configure.in: recognize m680x0 as having sun3 emulation mode for

8608 start addresses to match required alignment.
8610 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8612 * Makefile.in (install): Install into $(tooldir)/bin, since that's
8613 where gcc looks for it.
8615 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
8617 * Makefile.in: Changed some lines to be less confusing for some

8683 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
8685 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
8687 * expr.c (operand): if can't work out what sort of operand it is,
8688 then look through FLT_CHARS for a hint.
8690 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
8692 * Makefile.in, configure.in: removed traces of namesubdir,

8694 copyrights to '92, changed some from Cygnus to FSF.
8696 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
8697 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8698 copyrights to '92, changed some from Cygnus to FSF.
8700 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8702 * expr.c: If an expression is single comma, then return with
8703 SEG_ABSENT rather than an error - since the sparc front end does
8704 really strange things with things like fbge,a
8706 * as.h: include bfd.h if using many sections
8707 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8708 local labels didn't work.
8709 * listing.c (list_symbol_table): don't core dump when there's no
8711 * write.c, write.h: call fix_new with the right number of args on
8713 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8716 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8718 * app.c: MRI compatibility - allow single quote to start a string.
8719 * as.c: fix typo recently introduced.
8720 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8721 * expr.c: Much rewriting, to accomodate MRI syntax for
8722 expressions. Also easier to read now.
8723 * listing.c: Put back defuns
8724 * read.c: modified to accept MRI syntax, put back listing pseudo
8725 ops so that an assembler built with NO_LISTING ignores list ops
8727 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8728 machine is a SPARC or a 29K.
8729 * config/obj-aout.c: added s_sect pseudo op
8730 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8731 fill in the timestamp.
8732 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8733 anymore, define all the relocs which the tc-<x> bit will use so we
8734 can translate from them to the coff types.
8735 * config/tc-a29k.c: reloc_type isn't ane enum any more
8736 * config/tc-m68k.c: Added NO_RELOC definition.
8738 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8740 * Makefile.in: put header files before C source for TAGS; remove
8741 references to non-existent syscalls.h.
8743 * read.c, write.c subsegs.c: back out the .bss changes.
8745 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8747 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8751 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8753 * symbols.c (local_label_name): symbols now start with ^A.
8755 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8756 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8757 generate these sections. .align: will use NOP_OPCODE or 0
8758 for padding. This is just for being nice to the
8761 * expr.c (operand): changed to generate local label "\001L0"
8762 starting with a ^A so that it is recognized as a local label.
8764 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8766 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8767 i/o opcodes - inb, inw, outb and outw. string manipulation with
8768 att syntax - scmp, slod, smov, ssca, ssto.
8770 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8771 to just after .file .
8773 In obj_crawl_symbol_chain() where it tries to put the external
8774 symbols apart, with the condition:
8775 (!S_IS_DEFINED(symbolP) &&
8776 !S_IS_DEBUG(symbolP) &&
8777 !SF_GET_STATICS(symbolP))
8778 it was moving too many symbols out. So I switch it back to the
8780 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8782 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8783 so that we don't use the F_RELFLG which make the linker complain
8784 that somebody has stripped the relocation info.
8786 Also, the AIX ld program require that the relocation table
8787 is sorted by r_vaddr like the standard ATT assembler does.
8789 [he also changed the sizeof(struct ...)'s into the coff
8790 style FOOSZ macros. I'm not sure this is right, but I can't
8791 remember why. xoxorich.]
8793 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
8795 * Makefile.in, configure.in, doc: use the doc. Build it, install

8800 * read.c: white space and comments only.
8802 * configure.in: use the new atof-ns32.c for ns32k.
8804 * write.c: comment change only.
8806 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8807 aren't yet integrated.
8809 * tc-i860.[hc]: blew off the dust. Something must still be done
8810 about conflicting relocation types.
8812 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8815 * tc-i960.c, tc-sparc.c: white space and comments only.
8817 * tc-a29k.h: delete duplicate macro definition.
8819 * new file atof-ns32k.c copied from hack's last unreleased gas.
8821 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8823 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8826 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8827 ChangeLog's prior to this are sketchy at best. I have logs.
8828 They just aren't ChangeLogs.
8835 version-control: never
