2246 expression-valued symbol, and calling fix_new_exp recursively.
2247 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
2248 undefined symbol and a constant, fold the constant into the fixup,
2249 and refer to the undefined symbol directly. Then process the
2250 fixup again from scratch.

2386 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
2388 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
2389 many others): new macros; values obtained from "DSTRECRDS.SDL".
2390 * config/obj-vms.h (various): use them.
2391 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
2392 representation (only enum bitfields can avoid being bitstrings).
2393 (bitfield_suffix, setup_basic_type): new routines.
2394 (VMS_typedef_parse): use them. Now recognize bitfields of all
2395 integral types, not just type `int'. Caveat: the representation
2396 used for bitfields still does not work for objects placed in
2397 registers, and gcc's optimizer sometimes puts small structs there.
2399 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2401 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
2402 bit from const_flag.
2403 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
2404 (tc_frob_label): define this to call vms_check_for_special_label,
2405 and declare the latter.
2406 * config/obj-vms.c (vax_g_doubles): declare this file-scope
2408 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
2409 (vms_check_for_special_label): new routine (tc_frob_label).
2410 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
2411 and `gcc2_compiled.' labels; they won't reach here any more.
2412 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
2413 double', use `vax_g_doubles' flag to select type of double.
2414 (VMS_write_object_file) [traceback setup]: don't pass symbols
2415 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
2416 and TBT_Routine_End functions.

2420 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
2421 S_GET_VALUE() to avoid many repeated function calls.
2422 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
2423 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
2424 gets requested. [All the HACK_DEC_C_STARTUP code appears to
2425 be obsolete; gcc does it automatically for vms target. It's
2426 also misnamed, because it is for the "VAX C" run-time library,
2427 not the newer "DEC C" one which has much different startup code.]
2428 {various}: use `S_SET_xxx(symbol,new_value)' rather than
2429 `S_GET_xxx(symbol) = new_value'.
2431 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2433 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
2434 not &bfd_abs_section.
2436 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2438 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
2440 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
2442 * expr.c (expr): Don't reduce the difference of two symbols in the
2443 same frag if the symbols are not in normal sections.
2445 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
2446 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.

2450 (fix_new_hppa): Last arg is now a pointer to an int. Do not
2451 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
2452 fixups, store 32bits of unwind information in the fx_addnumber
2454 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
2455 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
2456 pointer to 32 bits of unwind info.
2457 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
2458 pointer to the dummy symbol; set the addend field to fx_addnumber.
2459 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
2460 rather than &bfd_XXX_section.
2462 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2464 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
2465 value by one; discard adjustments previously being made. From
2468 VMS- and Vax-related changes from Pat Rankin:
2469 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
2470 * vmsconf.sh: no longer have make-gas.com echo text about needing
2471 to modify the gcc-vms driver when intending to use with gcc 1.x.
2472 * as.c (parse_options): suppress 'v' from std_short_options and
2473 eliminate VMS-specific conditional initialization;
2474 [default case]: check for '-v' if md_parse_options doesn't recognize
2476 [default case, #if VMS]: check for filename argument when '-v' seen;
2478 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
2479 for O_big literal operands (double floats and long long ints);
2480 [VMS, md_shortopts]: add second colon after 'v';
2481 (md_parse_options) [VMS, case 'v']: check for argument, so
2482 caller can handle `-v' w/o arg.

2540 to ensure that older versions of autoconf aren't used.
2541 * Makefile.in: Added @configure_input@ line.
2542 (configure): Deleted rule.

2592 fixup is not local, to prevent relocations against externals from
2594 (md_assemble): Initialize disp_reloc field to NO_RELOC. Pass
2595 disp_reloc field to reloc() function, and use TC_RELOC to generate

2627 * ecoff.c (ecoff_build_symbols): If BSF_FUNCTION is set for an
2628 external symbol with no type, set the type to st_Proc rather than

2677 Update for autoconf beta 1.112:
2678 * aclocal.m4 (GAS_CHECK_DECL_NEEDED, GAS_WORKING_ASSERT): New
2680 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
2681 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
2682 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
2683 message to try to ease confusion about autoconf's
2684 "cross-compiling" message.
2685 * acconfig.h (NEED_DECLARATION_MALLOC, NEED_DECLARATION_FREE,
2686 NEED_DECLARATION_ERRNO): Renamed from NEED_*_DECLARATION.

2730 * Makefile.in (target_alias, program_transform_name): Define,
2731 using autoconf @-substitutions.
2733 Wed Aug 31 17:43:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

2740 autoconf 1.109 has this fixed.
2741 * configure.in: Don't change quote characters around AC_MSG_ERROR
2742 invocation. Don't use AC_HEADER_STDC, since it requires running a

3432 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
3433 to put a common symbol in a set.

3478 * read.c (emit_expr): Use memset to zero out memory, rather than
3479 going through md_number_to_chars. This permits handling symbolic

3533 (control_regs): New pointer.
3534 (m68k_ip): Use control_regs instead of testing CPU every time.
3535 Use last_movec_reg too. In error messages, handle 68060, and
3536 print 68060 for mfloat, too.
3537 (m68k_init_after_args): Handle "68060". Use m68040up for making
3538 m68851 choice. Set control_regs.

3831 also before setting STYP_NOLOAD for .bss section.
3833 * config/tc-m68k.c (flag_reg_prefix_optional): New variable.
3834 Initialized to value of REGISTER_PREFIX_OPTIONAL, if defined, or

3907 * config/tc-mips.c (append_insn): Permit branches to be switched
3908 with the preceding instruction even if .set nobopt has been seen.
3909 .set nobopt actually controls whether to bring up an instruction

3975 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
3977 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
3979 * vmsconf.sh: In generated file, get ".obj" suffix right, build
3980 source files from other directories into objects in the current
3981 directory, and specify PSECT attributes explicitly to linker.
3982 Also added missing label.

4050 elf_tc_make_sections stuff. It was there to support PA braindamage
4051 which has been fixed, and in the case of elf_tc_make_sections is
4052 redundant with elf_tc_final_processing.
4054 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4134 to make it pcrel_offset.
4135 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to

4150 tested by code that might want to emit a LITUSE reloc.
4151 (emit_unaligned_io): New function. Currently calls md_assemble,
4152 but it should eventually be converted to generate the insn itself
4153 and call emit_insn directly.

4155 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

4187 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
4188 -non_shared to use NO_PIC (this is how the Irix 5 assembler
4189 works). Do not permit -G with SVR4_PIC.
4190 (s_abicalls): Warn if -G was used, and force -G 0.
4191 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for

4209 MANY_SEGMENTS for any obj-coffbfd target.
4210 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
4211 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
4213 (LOCAL_LOADLIBES): Deleted.
4214 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
4215 * config/m88kcoff.mt (TDEFINES): Ditto.

4241 bfd_set_symtab is called.
4242 (dump_section_relocs): Note whether a symbol is a section symbol
4244 (adjust_reloc_syms): For now, always supply an absolute symbol for
4245 fixups without symbols but not yet `done'. Use section_symbol to
4246 get the symbol, instead of going directly for abs_symbol.
4247 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
4248 reloc is not a section symbol and is not in the symbol table.
4249 (set_symtab): New function, broken out from write_object_file.
4250 Counts symbol table instead of relying on an earlier count.
4251 (write_object_file): Call set_symtab, but do it after potentially
4252 invoking the *_frob_file macros. Don't bother counting symbols.
4253 Call symbol_remove, instead of expanding it in place. Moved the
4254 conditionalized `object_file_size' declaration down to
4255 conditionalized block where it's used. When using the absolute
4256 symbol for a fixup without a symbol, set sy_used_in_reloc.
4257 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
4258 the correct symbol for the absolute section.
4260 * subsegs.c (section_symbol): Use symbol_new instead of
4261 symbol_make, since we may want it to go into the symbol table.
4262 Make the new symbol have internal linkage. If
4263 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
4264 symbol with the newly created GAS symbol.
4265 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
4266 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

4273 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
4274 (sparc_ip, label "immediate"): Reject constants for pcrel
4275 instructions only if the relocation type indicates a "call"
4276 instruction and the offset is within range of a "jmpl %g0". If
4277 it's not in range, use the absolute section symbol plus an offset.
4278 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
4280 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
4282 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
4285 * configure.in: Eliminated all targets using obj-coff but not
4286 defining BFD_ASSEMBLER; I think all such targets that are
4287 supported will be matched by real CPU-OS combinations earlier in
4289 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
4290 some comments about the dpx2 configuration, but left it disabled,
4291 since it couldn't be reached before.
4292 (target a29k-amd-ebmonold): Deleted.

4302 the 'j' operand if there are no further alternatives for this
4305 * config/obj-coffbfd.c (adjust_stab_section): Initialize
4306 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
4307 is not SEG_UNKNOWN rather than checking whether it is >= 0.
4309 * config/tc-mips.c (mips_align): Take new argument, label, and use
4310 it instead of global insn_label.
4311 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
4312 call to mips_emit_delay and pass it to mips_align.
4314 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4316 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
4318 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
4319 argument to a .callinfo directive. Don't loop forever on errors.

4326 * write.c (write_object_file): Check both S_IS_LOCAL and
4327 S_IS_EXTERNAL when deciding whether to discard a symbol.
4329 * config-gas.com: Scan Makefile.in, not version.c, for current
4330 version number. Delete all versions of temp files when finished
4331 with them. Create config.h.
4333 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
4334 values to reduce number of lookups with S_GET_VALUE. Skip debug
4335 symbols to avoid "a really nasty bug". (From Holger Teutsch,
4336 holger@botbso.rhein-main.de.)
4337 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
4338 field. (Also from Holger Teutsch.) Watch for a would-be register
4339 mask that spans frags.
4341 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
4342 this_base, not line_base. (Patch from Andreas Arens,

4346 look local if they're exported or undefined. Used to be done for
4349 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

4353 (lex_type): Use it for `%'.
4355 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

6088 descriptor information to the BFD symbol.
6089 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

6140 pass new argument for i, j and o cases.
6141 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

6144 rather than hard coded constants.
6145 (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and

6362 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
6363 the table, require that the one without bit 0x1000000 set come

6476 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
6478 * configure.in: Set bfd_gas for all sparc targets. Added facility
6479 for keeping or rejecting configurations still under development;
6480 default is to assume production environment, and reject configs
6481 still being worked on. Mark Elf configurations (except sparc and
6482 i386) as developmental. Deleted cases matching some generic names
6483 in favor of more specific names. (E.g., when we get Alpha
6484 support, we'll still only support VMS for Vax.)

6500 through inclusion of tc-hppa.h. Delete all forward declarations
6501 for functions only used within tc-hppa.c, likewise for structures,
6502 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
6503 conditional code in a few small places.
6505 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
6506 structures, global variables, forward declarations together.

6508 conditional code -- try to group conditional code together
6509 into a few places. Make all functions and variables which
6510 are only used within tc-hppa.c static. PARAMize all functions.
6511 Add comments to functions. Delete unused functions, variables,
6512 #defines, etc. Delete unused members within structures. Delete
6513 ldil;ble hacks -- it is believed they were installed to work
6514 around old gas bugs. Avoid using mixed case for local
6515 functions, variables, and structures. Fix formatting problems
6516 not found by GNU-indent. Add FIXME notices for things which
6517 should be worked on the near future. Delete lots of old
6518 useless (1.36 PA-SOM) code.
6520 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
6521 field of the fixS structure. Needed to build unwind

7680 * Extensive changes to permit symbols to contain any expression
7681 type and to delay the computation of the expression until the
7682 value is actually needed. This permits setting symbols to values
7683 calculated based on object code size. Expressions were changed to
7684 no longer be in a section, to stop the overloading of segment and
7685 expression type that previously occurred.
7687 * as.c (big_section, pass1_section, diff_section, absent_section):
7689 (expr_section): Added (used for dummy symbols which hold

7799 calculating opP->isiz; this permits the expression size to be
7800 determined as well, later on.

7814 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
7816 * read.c (float_cons): Simplified parsing logic. If
7817 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.

8924 than ECOFF line number information.
8925 (obj_ecoff_stab): Accept non-zero values for stabs line number.

8986 dependencies are read, not when they are used).
8988 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
8989 a29k .bss section; the mondfe program doesn't like it.

9010 source directory, if that's not the current directory.
9012 * configure.in (per-host): Accept MIPS host with BSD version

9033 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
9034 process relocs if there aren't any relocs to process. Avoids
9035 malloc/free bug on SCO too.

9038 avoid some redefinition complaints on some systems.
9039 (const, volatile): Don't need these conditionally defined if we
9040 use CONST and VOLATILE from ansidecl.h.
9041 (seg_name): Use CONST, not const.
9043 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
9045 * config/tc-mips.c: Reindented to GNU standards.
9047 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
9049 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
9050 (fixup_segment): Add a29k special case; the linker is not prepared
9051 to see a segment offset here.
9053 * app.c (do_scrub_next_char): Added new state, 10, modifying state
9054 9 to only keep a space in between identifier characters.
9056 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
9058 * Makefile.in: add dvi target; as-$(config).texinfo might live in
9059 srcdir, might be in objdir.
9061 * doc/Makefile.in: dvi depends on as.dvi

9079 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
9080 bignums, but don't emit error message.
9082 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
9084 * Makefile.in (targ-cpu.o): Depend on config.h.
9086 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
9088 * app.c (do_scrub_next_char): Added new state, 9, to avoid
9089 dropping a space immediately following an identifier.
9090 * expr.c, write.c: Rewrote assert expressions to not use multiple
9091 lines; I don't think that can be done portably.
9092 * config/tc-mips.c (macro): Use $AT if target register is zero in
9093 load instruction, which it can be for a floating point load.
9095 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

9103 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
9106 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
9107 z8k-opc.h, not z8k.h.
9109 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
9112 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9114 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
9116 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
9118 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
9119 to be on a single line.
9121 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
9123 * Makefile.in (config.h): Create file, writing out definitions of

9163 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
9164 (struct loc, struct proc, struct file): Moved to tc-mips.c within
9165 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
9166 * config/tc-mips.c: Rearranged for ECOFF support. Added
9167 prototypes for all static functions. Moved existing minimal
9168 debugging format support info #ifndef OBJ_ECOFF blocks.
9169 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
9170 does not support a non sign extended high 16 bits reloc. Adjusted
9171 all callers accordingly.
9172 (tc_get_register): Renamed from get_register, and made non-static.
9174 * config/mips-big.mt, config/mips-lit.mt: New files. Define

9217 * make-gas.com: Find obstack.obj if it's not in the current
9219 * read.c (s_ignore): Don't declare is_end_of_line. It's
9220 redundant, and triggers a VMS gcc compiler bug.
9222 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
9223 current segment as an argument. (Ignored in all cases but VMS.)
9224 All callers and definitions changed.
9226 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
9228 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING

9242 argument to s_ignore. Put "#if 0" around unused code.
9243 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
9244 Call elf_xstabs for .stabs and .xstabs operators.
9246 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
9248 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
9251 * configure.in: mips-bsd configuration was missing format spec.
9254 * Makefile.in (Makefile): Depends on configure.in.
9256 * config/tc-mips.c (append_insn): Don't check for alignment of
9257 frag in memory; alignment of instructions in section is a separate

9277 * config/tc-sparc.c (s_xword): Now call big_cons, so large
9278 constants are accepted, but symbolic values are not. GCC will not
9279 generate the latter currently.
9281 * frags.c (frag_init): New function.
9282 (zero_address_frag, bss_address_frag): Now initialized at run
9284 * as.c (main): Call frag_init.

9314 "IGNORE_DEBUG" conditional, since both branches are identical.
9315 Use S_SET_TYPE, S_GET_TYPE, and S_GET_DESC instead of directly
9316 referencing symbol structure members.
9317 (obj_aout_frob_symbol) [BFD_ASSEMBLER]: New function.
9319 * as.h (struct frag): Reordered a couple of fields for better

9327 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
9328 (fixup_segment): Make sure common-section symbols get treated the
9329 same as undefined symbols.
9330 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type
9331 bfd_reloc_code_real_type. Use seg_fix_{root,tail}P derived from
9333 * write.h (fix_new): Update prototype.
9335 * tc.h (md_operand, md_convert_frag, tc_headers_hook,
9336 md_section_align, md_undefined_symbol): Don't provide prototypes
9337 if these are defined as macros.

9341 * symbols.c (symbol_new): Argument NAME is now pointer to const.
9342 Simplified STRIP_UNDERSCORE code. Remove assumptions about null
9343 pointers in freshly allocated storage. [BFD_ASSEMBLER]: Get new
9345 (colon): Display other/desc fields of redefined symbol only if

9536 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
9537 latter, instead of selecting with preprocessor conditionals.
9539 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9541 * configure.in: recognise all sparclite variants

9551 * expr.c (operand): If character other than comma or newline is a
9552 logical end-of-line character, use the newline case.
9553 From Eric Youngdale:
9554 (operand): Set X_add_number field for floating-point numbers.
9555 (operand): Treat zero byte as end-of-operand.
9557 * configure.in (per-target): Look for with_bfd_assembler option.
9558 For now, only accept "no", until the merge is done.
9560 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
9561 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
9562 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
9563 * read.c: Finish conversion to S_* macros in the VMS only
9564 parts of the program. Add "const" modifier to hex_value.
9565 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
9567 * expr.c: Add "const" modifier to hex_value.
9568 * symbols.c: Finish conversion to S_* macros in the VMS only
9569 parts of the program. Add "const" modifier to
9570 md_[long,short]_jump_size. Remove declaration of const_flag
9571 (which will be declared in obj-vms.h).
9572 * write.c: Add "const" modifier to md_[long,short]_jump_size.
9573 Fix arguments to VMS_write_object_file.
9574 * config-gas.com: New file. Script for VMS systems to set up the
9575 configuration to build gas for VMS, and create config.status.
9576 * make-gas.com: Redone to work with new scheme.
9577 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
9579 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
9580 will swap bytes if needed on a big endian system. Use throughout
9582 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
9583 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
9584 types of malformed stabs. Change parsing algorithm so that we are
9585 more certain of having all of the information that we need on hand.
9586 * obj-vms.c (final_forward_reference): New function, used to help
9587 resolve the data types of as many struct elements as possible
9588 when some part of the struct is not fully defined by the compiler.

9591 * obj-vms.c (VMS_write_object_file): Define all vtable psects
9592 as symbols as well in the object file. Look for external functions

9594 g++ compiler is incapable of doing this.
9595 * tc-vax.c: Add '1' option for backward compatibility with older GCC
9597 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
9598 * input-scrub.c (as_where): Fix bug where as would crash if we did not
9599 have the name of the source file yet.
9600 * config/ho-vms.h: define HO_VMS, not HO_VAX.
9602 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
9604 * read.c (s_data): Always use "data_section", since it'll map to
9605 SEG_DATA or SEG_E1 if needed.
9606 (s_lcomm): Likewise with bss_section.
9607 (s_fill): Use memset, not bzero.
9609 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

9631 (big_section, reg_section, pass1_section, diff_section,
9632 absent_section, text_section, data_section, bss_section): If
9633 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
9634 mapping to segT enum values.
9635 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
9636 if these are used or defined, if BFD_ASSEMBLER.
9637 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
9638 subseg_new split into two functions.
9639 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
9641 * as.h (volatile): Don't define if already defined.
9642 (had_errors, had_warnings): Provide prototypes for ANSI C even if
9644 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
9645 declare with format attribute for -Wformat checking.
9647 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
9649 * app.c, config/tc-*.c: Don't include read.h, since it is already
9652 * These are based on patches from Minh Tran-le
9653 <mtranle@paris.intellicorp.com>.
9654 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
9655 obj_format coffbfd and gas_target i386coff for target.
9656 (i[34]86-*-isc*): New host (uses sysv).
9657 * config/i386aix.mt: Removed (no longer used).
9658 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
9660 (LDFLAGS): Added, defined as -shlib.
9661 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
9662 * config/te-sco386.h (LOCAL_LABEL): Don't define.
9663 (DOT_LABEL_PREFIX): Define.
9664 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
9665 name rather than L0\001.

9677 (size_section): Restored sanity check.
9678 (do_relocs_for): Base section address on s_paddr rather than
9679 computing it. Adjust a29k R_IHIHALF special case to account for
9680 section paddr (used to require paddr to be zero). If there are no
9681 reclos, set s_relptr to 0. Set relocation size in object_headers.
9682 (fill_section): Always set s_vaddr here, removing
9683 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
9684 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
9685 Set STYP_INFO for .comment.
9686 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
9687 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

9689 H_{SET,GET}_* macros.
9690 (do_linenos_for): Set lineno size in object_headers.
9691 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
9692 set s_vaddr here. If string_byte_count remains 4, set it back to
9693 0, and only write strings out if there are some. Call
9694 fill_section before do_relocs_for and do_linenos_for.
9695 (obj_coff_section): Handle optional quoted second argument giving
9696 section characteristics.
9697 (obj_coff_bss): Added to handle .bss.
9698 (obj_coff_ident): Added to handle .ident (puts string in .comment

9718 (do_scrub_next_char): For \", return " not '.
9719 (symbol_chars): Now const.
9721 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
9722 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
9724 * config/obj-coff.h: Don't use #elif.
9726 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
9727 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
9729 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
9731 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

9745 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
9747 * listing.c: Call xmalloc, not malloc; don't declare malloc.
9749 * Changes to support SCO 3.2v4:

9751 SEG_BSS, fill with NOP_OPCODE.
9752 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
9753 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
9754 using ZERO_BASED_SEGMENTS.
9755 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
9756 never set segment address for SEG_E2 (.bss) and don't write out
9757 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
9758 (obj_coff_endef): Don't merge labels or symbols awaiting forward
9759 definitions, and don't merge tags with non-tags. Check for .bf
9760 rather than just checking whether the second character is b and
9761 the third character is f.
9762 (obj_coff_val): gcc can generate values which we don't handle
9763 correctly; discard information for now, since it only affects the
9764 debugging information.
9765 (tag_find_or_name): Don't insert tags in the symbol table.
9766 (yank_symbols): Don't merge labels.
9767 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

9784 Mon Dec 7 00:39:09 1992 Ken Raeburn (raeburn@cygnus.com)
9786 * config/tc-i386.c (md_pseudo_table): For 386bsd and linux, do
9787 power-of-two alignment for .align.
9789 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
9790 and leave everything else alone.

9918 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
9921 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
9923 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

10031 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
10032 #elif, since it is not supported by old compilers.
10033 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
10034 couple of expressions in tc-m68k.c.
10036 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10038 * read.c (cons): If NO_RELOC is defined, use it.

10045 local labels to start with a .) and set REGISTER_PREFIX to %.
10046 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
10048 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

10059 * listing.c (debugging_pseudo): Add stabs and stabn as things to
10062 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
10064 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
10065 sections starting from zero, rather than making them consecutive.
10066 This makes subsequent reloc calculations easier, esp if the object
10067 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
10068 allocate lcomm in .data rather than in .bss. It seems that some
10069 tools can't cope with a non-zero sized bss before linkage.
10071 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10073 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10074 throughout. That enum no longer means what we thought it meant.

10077 "-mno-688[58]1" options.
10079 * tc-m68k.c: Added CPU32 support.

10092 * Makefile.in (install): if $(tooldir) exists, install as in
10095 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10097 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10098 .word is < -32768 or > 32767. The -J flag causes the error to be
10099 ignored. This is to catch over-sized switches generated by gcc on
10100 systems which don't support the broken .word hack.
10101 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10102 write.c (fixup_segment): check for signed .word overflow if
10103 WARN_SIGNED_OVERFLOW_WORD.
10105 * write.c (fixup_segment): fixed missing parens in expression
10106 checking for byte or word overflow.
10108 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
10109 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
10110 WARN_SIGNED_OVERFLOW_WORD.

10122 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
10124 * input-scrub.c (input_scrub_push): call input_file_begin, not
10126 messages.c (as_perror): print ": " between the passed in error and
10127 the strerror, like perror does.
10129 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

10136 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
10137 Motorola and MIT syntax; gas can now assemble either type of
10139 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
10140 From Steve Chamberlain:
10141 m68kcoff.mt: for m68k COFF.
10142 obj-coffbfd.c: (fixup_mdeps) added
10143 (size_section) removed bad sanity check
10144 (fill_section) added rs_machine_dependent case
10145 (write_object_file) call fixup_mdeps
10146 (fixup_segment) set fx_subsy to 0.
10147 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
10149 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
10152 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

10176 tc-i960.c (md_ri_to_chars): Always output bout object file in
10177 little endian byte order (used to use endianness of host).
10179 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10181 * config/tc-m68k.c (init_table): Now const. Always include 68851
10182 data, so that "bc" is available to 68040 cache instructions.
10183 Added "tt0", "tt1", and 68ec030 variants.
10184 (md_assemble): Complain if 68000 (only) and 68881 are specified.
10185 (enum _register): Added TT0, TT1.
10186 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
10187 line number correctly in "internal error" messages. Don't print
10188 architecture-mismatch message for operand errors.
10190 From Colin Smith (colin@wrs.com):
10191 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
10192 than install_operand.

10201 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
10203 * Makefile.in: defined TARGET_CPU for C code so that it can choose
10204 one element of a family.
10206 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
10208 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
10209 so that we can assemble hand-written libgcc code.
10211 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10213 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
10214 has already been formatted (but may still contain %-characters).
10215 (as_bad): Likewise.
10217 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
10219 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
10220 written with indirection on the last two operands, which can be
10221 either data or address registers. Added a new operand type 'r'
10222 which accepts either register type. Added '(' to notend stuff in
10223 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
10225 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
10227 * as.h (enum _relax_state): Start off at one, not zero, to better
10228 catch uninitialized-variable errors.
10229 (linkrelax): Declare new variable.
10231 * messages.c (warning_count, error_count): Default initializer is
10234 * write.c: Merged some declarations, using PARMS macro.

10236 data_last_frag): No longer static.
10237 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
10238 defined, call it. Change segments before calling fixup_segment.
10239 (relax_align): If linkrelax, provide extra padding.
10241 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
10242 their not having symbols associated.
10244 * tc-i960.c (norelax, instrument_branches): Default initializer is
10246 (linkrelax): Delete variable definition.

10269 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
10270 being used with args swapped, causing occasional lossage when
10271 refilling buffers after an include file.
10273 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
10275 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
10276 version. Discard bogus DONTDEF version.

10281 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
10282 selected architecture, print a message saying so and listing what
10283 processors support it, rather than saying "operands mismatch".

10474 * Makefile.in (install): Install into $(tooldir)/bin, since that's

10519 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
10521 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

10545 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
10547 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
10549 * expr.c (operand): if can't work out what sort of operand it is,
10550 then look through FLT_CHARS for a hint.
10552 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
10554 * Makefile.in, configure.in: removed traces of namesubdir,
10555 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10556 copyrights to '92, changed some from Cygnus to FSF.
10558 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
10559 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10560 copyrights to '92, changed some from Cygnus to FSF.
10562 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10564 * expr.c: If an expression is single comma, then return with
10565 SEG_ABSENT rather than an error - since the sparc front end does
10566 really strange things with things like fbge,a
10568 * as.h: include bfd.h if using many sections
10569 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
10570 local labels didn't work.
10571 * listing.c (list_symbol_table): don't core dump when there's no
10573 * write.c, write.h: call fix_new with the right number of args on
10575 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
10578 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10580 * app.c: MRI compatibility - allow single quote to start a string.
10581 * as.c: fix typo recently introduced.
10582 * as.h : Don't include aout/reloc.h - it's not right for COFF!
10583 * expr.c: Much rewriting, to accomodate MRI syntax for
10584 expressions. Also easier to read now.
10585 * listing.c: Put back defuns
10586 * read.c: modified to accept MRI syntax, put back listing pseudo
10587 ops so that an assembler built with NO_LISTING ignores list ops
10589 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
10590 machine is a SPARC or a 29K.
10591 * config/obj-aout.c: added s_sect pseudo op
10592 * config/obj-coffbfd.c: lints, set the filehdr flags right and
10593 fill in the timestamp.
10594 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
10595 anymore, define all the relocs which the tc-<x> bit will use so we
10596 can translate from them to the coff types.
10597 * config/tc-a29k.c: reloc_type isn't ane enum any more
10598 * config/tc-m68k.c: Added NO_RELOC definition.
10600 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10602 * Makefile.in: put header files before C source for TAGS; remove
10603 references to non-existent syscalls.h.
10605 * read.c, write.c subsegs.c: back out the .bss changes.
10607 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
10609 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
10611 * a.out.h: removed.
10613 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
10615 * symbols.c (local_label_name): symbols now start with ^A.
10617 * read.c, subsegs.c, write.c obj-coff.c: added handling of
10618 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
10619 generate these sections. .align: will use NOP_OPCODE or 0
10620 for padding. This is just for being nice to the
10623 * expr.c (operand): changed to generate local label "\001L0"
10624 starting with a ^A so that it is recognized as a local label.
10626 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
10628 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
10629 i/o opcodes - inb, inw, outb and outw. string manipulation with
10630 att syntax - scmp, slod, smov, ssca, ssto.
10632 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
10633 to just after .file .
10635 In obj_crawl_symbol_chain() where it tries to put the external
10636 symbols apart, with the condition:
10637 (!S_IS_DEFINED(symbolP) &&
10638 !S_IS_DEBUG(symbolP) &&
10639 !SF_GET_STATICS(symbolP))
10640 it was moving too many symbols out. So I switch it back to the
10642 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
10644 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
10645 so that we don't use the F_RELFLG which make the linker complain
10646 that somebody has stripped the relocation info.
10648 Also, the AIX ld program require that the relocation table
10649 is sorted by r_vaddr like the standard ATT assembler does.
10651 [he also changed the sizeof(struct ...)'s into the coff
10652 style FOOSZ macros. I'm not sure this is right, but I can't
10653 remember why. xoxorich.]
10655 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
10657 * Makefile.in, configure.in, doc: use the doc. Build it, install
10660 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
10662 * read.c: white space and comments only.
10664 * configure.in: use the new atof-ns32.c for ns32k.
10666 * write.c: comment change only.
10668 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
10669 aren't yet integrated.
10671 * tc-i860.[hc]: blew off the dust. Something must still be done
10672 about conflicting relocation types.
10674 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
10677 * tc-i960.c, tc-sparc.c: white space and comments only.
10679 * tc-a29k.h: delete duplicate macro definition.
10681 * new file atof-ns32k.c copied from hack's last unreleased gas.
10683 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
10685 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
10688 * nearly everything. flush ChangeLog, package as gas-1.92.1.
10689 ChangeLog's prior to this are sketchy at best. I have logs.
10690 They just aren't ChangeLogs.
