2082 ecoff_frob_symbol if appropriate.
2084 * write.c (fixup_segment): For i386 elf and coff (for now), don't

2188 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2190 * configure.in: Set bfd_gas for all sparc targets in one place,
2191 instead of separately for each. Correctly handle user-supplied
2192 "--enable-bfd-gas" option.
2194 * gdbinit.in: Move "break abort" to end, in case gdb complains.
2196 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:

2204 (indent_level): No longer static.
2205 (print_symbol_value_1): Don't print frag address if it matches

2214 * write.c (fix_new_exp): Handle O_add by creating an
2215 expression-valued symbol, and calling fix_new_exp recursively.
2216 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
2217 undefined symbol and a constant, fold the constant into the fixup,
2218 and refer to the undefined symbol directly. Then process the
2219 fixup again from scratch.
2220 (write_object_file): Before calling adjust_reloc_syms, make a pass
2221 through the symbol list trying to resolve values.
2223 * write.c (print_fixup): New routine, for debugging.
2224 (write_relocs): Call bfd_install_relocation. Deleted various

2242 * write.c (write_relocs): Add file name and line number to
2243 as_fatal calls. Handle bfd_reloc_overflow case specifically when
2244 RELOC_EXPANSION_POSSIBLE.
2246 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2248 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these

2253 default definitions matching what we were doing before.
2254 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
2255 always use the varargs form if not using stdarg. It's safe to
2256 always use vfprintf, because libiberty will provide it if the

2276 false (if defined) as well as checking for reg_section.
2277 (listing_listing): Iterate fetching lines while line number is too
2278 low, and we haven't run off the end of the input file.
2280 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
2282 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

2298 X_add_number is zero.
2299 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.

2305 md_estimate_size_before_relax, md_ri_to_chars,
2306 md_create_short_jump, md_create_long_jump.
2307 (brtab_emit): Use data_section, not SEG_DATA.
2309 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2311 * config/vms-conf.h: new file, manually derived from conf.in.

2325 * config/tc-mips.c (insns_since_cache_access): Remove.
2326 (append_insn): Remove setting of insns_since_cache_access, and

2329 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2331 * config/tc-mips.c (md_shortopts): Remove E.
2332 (md_longopts): Add EB and EL.
2333 (md_parse_option): Handle -EB and -EL as separate options, rather
2334 than as a single -E option with an argument.

2338 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
2339 involving global symbols too.
2341 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2343 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
2345 * configure.in: Test for remove, not delete. Fix cross-assembler

2361 representation (only enum bitfields can avoid being bitstrings).
2362 (bitfield_suffix, setup_basic_type): new routines.
2363 (VMS_typedef_parse): use them. Now recognize bitfields of all
2364 integral types, not just type `int'. Caveat: the representation
2365 used for bitfields still does not work for objects placed in
2366 registers, and gcc's optimizer sometimes puts small structs there.
2368 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2370 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
2371 bit from const_flag.
2372 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.

2377 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
2378 (vms_check_for_special_label): new routine (tc_frob_label).
2379 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
2380 and `gcc2_compiled.' labels; they won't reach here any more.
2381 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
2382 double', use `vax_g_doubles' flag to select type of double.
2383 (VMS_write_object_file) [traceback setup]: don't pass symbols
2384 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin

2392 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
2393 gets requested. [All the HACK_DEC_C_STARTUP code appears to
2394 be obsolete; gcc does it automatically for vms target. It's
2395 also misnamed, because it is for the "VAX C" run-time library,
2396 not the newer "DEC C" one which has much different startup code.]
2397 {various}: use `S_SET_xxx(symbol,new_value)' rather than
2398 `S_GET_xxx(symbol) = new_value'.

2421 fixups, store 32bits of unwind information in the fx_addnumber
2423 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
2424 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
2425 pointer to 32 bits of unwind info.
2426 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
2427 pointer to the dummy symbol; set the addend field to fx_addnumber.

2434 value by one; discard adjustments previously being made. From
2437 VMS- and Vax-related changes from Pat Rankin:
2438 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
2439 * vmsconf.sh: no longer have make-gas.com echo text about needing
2440 to modify the gcc-vms driver when intending to use with gcc 1.x.
2441 * as.c (parse_options): suppress 'v' from std_short_options and
2442 eliminate VMS-specific conditional initialization;
2443 [default case]: check for '-v' if md_parse_options doesn't recognize

2447 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
2448 for O_big literal operands (double floats and long long ints);
2449 [VMS, md_shortopts]: add second colon after 'v';
2450 (md_parse_options) [VMS, case 'v']: check for argument, so

2649 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
2650 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
2651 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
2652 message to try to ease confusion about autoconf's

3401 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
3402 to put a common symbol in a set.

3447 * read.c (emit_expr): Use memset to zero out memory, rather than
3448 going through md_number_to_chars. This permits handling symbolic

3501 m68040_control_regs, m68060_control_regs): New arrays.
3502 (control_regs): New pointer.
3503 (m68k_ip): Use control_regs instead of testing CPU every time.
3504 Use last_movec_reg too. In error messages, handle 68060, and
3505 print 68060 for mfloat, too.
3506 (m68k_init_after_args): Handle "68060". Use m68040up for making
3507 m68851 choice. Set control_regs.

4019 elf_tc_make_sections stuff. It was there to support PA braindamage
4020 which has been fixed, and in the case of elf_tc_make_sections is
4021 redundant with elf_tc_final_processing.

4124 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

4158 works). Do not permit -G with SVR4_PIC.
4159 (s_abicalls): Warn if -G was used, and force -G 0.
4160 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for

4209 * write.c (symbol_table_frozen): New variable, to be set after
4210 bfd_set_symtab is called.
4211 (dump_section_relocs): Note whether a symbol is a section symbol
4213 (adjust_reloc_syms): For now, always supply an absolute symbol for
4214 fixups without symbols but not yet `done'. Use section_symbol to
4215 get the symbol, instead of going directly for abs_symbol.
4216 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
4217 reloc is not a section symbol and is not in the symbol table.
4218 (set_symtab): New function, broken out from write_object_file.
4219 Counts symbol table instead of relying on an earlier count.
4220 (write_object_file): Call set_symtab, but do it after potentially
4221 invoking the *_frob_file macros. Don't bother counting symbols.
4222 Call symbol_remove, instead of expanding it in place. Moved the
4223 conditionalized `object_file_size' declaration down to
4224 conditionalized block where it's used. When using the absolute
4225 symbol for a fixup without a symbol, set sy_used_in_reloc.
4226 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
4227 the correct symbol for the absolute section.
4229 * subsegs.c (section_symbol): Use symbol_new instead of
4230 symbol_make, since we may want it to go into the symbol table.
4231 Make the new symbol have internal linkage. If
4232 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
4233 symbol with the newly created GAS symbol.
4234 (obj_sec_sym_ok_for_reloc): Default to always returning 0.

4242 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
4243 (sparc_ip, label "immediate"): Reject constants for pcrel
4244 instructions only if the relocation type indicates a "call"
4245 instruction and the offset is within range of a "jmpl %g0". If
4246 it's not in range, use the absolute section symbol plus an offset.
4247 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
4249 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
4251 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
4254 * configure.in: Eliminated all targets using obj-coff but not
4255 defining BFD_ASSEMBLER; I think all such targets that are
4256 supported will be matched by real CPU-OS combinations earlier in
4258 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
4259 some comments about the dpx2 configuration, but left it disabled,
4260 since it couldn't be reached before.
4261 (target a29k-amd-ebmonold): Deleted.

4271 the 'j' operand if there are no further alternatives for this
4274 * config/obj-coffbfd.c (adjust_stab_section): Initialize
4275 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
4276 is not SEG_UNKNOWN rather than checking whether it is >= 0.
4278 * config/tc-mips.c (mips_align): Take new argument, label, and use
4279 it instead of global insn_label.
4280 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
4281 call to mips_emit_delay and pass it to mips_align.
4283 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4285 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.

4299 version number. Delete all versions of temp files when finished
4300 with them. Create config.h.

4303 values to reduce number of lookups with S_GET_VALUE. Skip debug
4304 symbols to avoid "a really nasty bug". (From Holger Teutsch,
4305 holger@botbso.rhein-main.de.)
4306 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
4307 field. (Also from Holger Teutsch.) Watch for a would-be register
4308 mask that spans frags.
4310 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
4311 this_base, not line_base. (Patch from Andreas Arens,

4315 look local if they're exported or undefined. Used to be done for
4318 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

6450 still being worked on. Mark Elf configurations (except sparc and
6451 i386) as developmental. Deleted cases matching some generic names
6452 in favor of more specific names. (E.g., when we get Alpha

6479 are only used within tc-hppa.c static. PARAMize all functions.
6480 Add comments to functions. Delete unused functions, variables,
6481 #defines, etc. Delete unused members within structures. Delete
6482 ldil;ble hacks -- it is believed they were installed to work
6483 around old gas bugs. Avoid using mixed case for local
6484 functions, variables, and structures. Fix formatting problems
6485 not found by GNU-indent. Add FIXME notices for things which
6486 should be worked on the near future. Delete lots of old

7649 * Extensive changes to permit symbols to contain any expression
7650 type and to delay the computation of the expression until the
7651 value is actually needed. This permits setting symbols to values
7652 calculated based on object code size. Expressions were changed to
7653 no longer be in a section, to stop the overloading of segment and
7654 expression type that previously occurred.
7656 * as.c (big_section, pass1_section, diff_section, absent_section):
7658 (expr_section): Added (used for dummy symbols which hold

7742 (previous_section, previous_subsection): New vars.
7743 (obj_elf_section): Save current place in case DWARF code wants us
7744 to pop back to it. Handle unquoted section name as well as quoted
7745 section name. Don't crash on invalid strings.
7746 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

7783 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
7785 * read.c (float_cons): Simplified parsing logic. If
7786 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.

7834 (omagic): Removed unused variable.
7836 * Preliminary support for m88k-coff.

7855 * Removed sy_forward and replaced it with an undefined expression
7856 as the value of a symbol.
7857 * struc-symbol.h (struct symbol): Removed sy_forward field. Added
7858 sy_resolved and sy_resolving single bit fields.
7859 * symbols.c (symbol_new): Don't initialize sy_forward field.
7860 (resolve_symbol_value): New function to adjust symbol value by
7861 fragment address, using recursion to resolve forward symbols.

7863 * read.c (pseudo_set): Set symbolP->sy_value to an undefined
7864 expression rather than setting symbolP->sy_forward.
7865 * write.c (write_object_file): Use resolve_symbol_value on
7866 symbols, keeping the common case (the old behaviour) inline.

8893 than ECOFF line number information.
8894 (obj_ecoff_stab): Accept non-zero values for stabs line number.

8953 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
8954 the bottom (make expands variables in dependencies when the
8955 dependencies are read, not when they are used).
8957 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
8958 a29k .bss section; the mondfe program doesn't like it.

8979 source directory, if that's not the current directory.
8981 * configure.in (per-host): Accept MIPS host with BSD version

9003 process relocs if there aren't any relocs to process. Avoids
9004 malloc/free bug on SCO too.

9007 avoid some redefinition complaints on some systems.
9008 (const, volatile): Don't need these conditionally defined if we
9009 use CONST and VOLATILE from ansidecl.h.
9010 (seg_name): Use CONST, not const.
9012 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
9014 * config/tc-mips.c: Reindented to GNU standards.
9016 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
9018 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
9019 (fixup_segment): Add a29k special case; the linker is not prepared
9020 to see a segment offset here.
9022 * app.c (do_scrub_next_char): Added new state, 10, modifying state
9023 9 to only keep a space in between identifier characters.
9025 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
9027 * Makefile.in: add dvi target; as-$(config).texinfo might live in
9028 srcdir, might be in objdir.
9030 * doc/Makefile.in: dvi depends on as.dvi

9048 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
9049 bignums, but don't emit error message.
9051 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
9053 * Makefile.in (targ-cpu.o): Depend on config.h.
9055 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
9057 * app.c (do_scrub_next_char): Added new state, 9, to avoid
9058 dropping a space immediately following an identifier.
9059 * expr.c, write.c: Rewrote assert expressions to not use multiple
9060 lines; I don't think that can be done portably.
9061 * config/tc-mips.c (macro): Use $AT if target register is zero in
9062 load instruction, which it can be for a floating point load.
9064 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

9072 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
9075 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
9076 z8k-opc.h, not z8k.h.
9078 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
9081 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9083 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
9085 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
9087 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
9088 to be on a single line.

9136 prototypes for all static functions. Moved existing minimal
9137 debugging format support info #ifndef OBJ_ECOFF blocks.

9139 does not support a non sign extended high 16 bits reloc. Adjusted
9140 all callers accordingly.
9141 (tc_get_register): Renamed from get_register, and made non-static.

9186 * make-gas.com: Find obstack.obj if it's not in the current
9188 * read.c (s_ignore): Don't declare is_end_of_line. It's
9189 redundant, and triggers a VMS gcc compiler bug.
9191 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
9192 current segment as an argument. (Ignored in all cases but VMS.)
9193 All callers and definitions changed.

9209 (obj_elf_xstab): New routine.
9210 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
9211 argument to s_ignore. Put "#if 0" around unused code.
9212 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
9213 Call elf_xstabs for .stabs and .xstabs operators.
9215 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
9217 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
9220 * configure.in: mips-bsd configuration was missing format spec.
9223 * Makefile.in (Makefile): Depends on configure.in.
9225 * config/tc-mips.c (append_insn): Don't check for alignment of
9226 frag in memory; alignment of instructions in section is a separate
9229 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI

9246 * config/tc-sparc.c (s_xword): Now call big_cons, so large
9247 constants are accepted, but symbolic values are not. GCC will not
9248 generate the latter currently.
9250 * frags.c (frag_init): New function.
9251 (zero_address_frag, bss_address_frag): Now initialized at run
9253 * as.c (main): Call frag_init.

9285 referencing symbol structure members.
9286 (obj_aout_frob_symbol) [BFD_ASSEMBLER]: New function.
9288 * as.h (struct frag): Reordered a couple of fields for better

9296 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
9297 (fixup_segment): Make sure common-section symbols get treated the
9298 same as undefined symbols.
9299 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type
9300 bfd_reloc_code_real_type. Use seg_fix_{root,tail}P derived from
9302 * write.h (fix_new): Update prototype.
9304 * tc.h (md_operand, md_convert_frag, tc_headers_hook,
9305 md_section_align, md_undefined_symbol): Don't provide prototypes
9306 if these are defined as macros.
9307 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and
9310 * symbols.c (symbol_new): Argument NAME is now pointer to const.
9311 Simplified STRIP_UNDERSCORE code. Remove assumptions about null
9312 pointers in freshly allocated storage. [BFD_ASSEMBLER]: Get new

9328 (subseg_set) [BFD_ASSEMBLER]: New function; change to a possibly
9329 new section/subsection.
9331 * read.c: Don't include ctype.h.
9332 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
9333 for now; should be machine-dependent.
9335 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
9336 targets, forcing BFD use.
9338 Wed Feb 17 18:59:03 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
9340 * config/tc-sparc.c: Use PARAMS macro for static function

9506 latter, instead of selecting with preprocessor conditionals.
9508 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9510 * configure.in: recognise all sparclite variants

9520 * expr.c (operand): If character other than comma or newline is a
9521 logical end-of-line character, use the newline case.
9522 From Eric Youngdale:
9523 (operand): Set X_add_number field for floating-point numbers.
9524 (operand): Treat zero byte as end-of-operand.
9526 * configure.in (per-target): Look for with_bfd_assembler option.
9527 For now, only accept "no", until the merge is done.
9529 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
9530 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

9536 * expr.c: Add "const" modifier to hex_value.
9537 * symbols.c: Finish conversion to S_* macros in the VMS only
9538 parts of the program. Add "const" modifier to
9539 md_[long,short]_jump_size. Remove declaration of const_flag
9540 (which will be declared in obj-vms.h).
9541 * write.c: Add "const" modifier to md_[long,short]_jump_size.
9542 Fix arguments to VMS_write_object_file.
9543 * config-gas.com: New file. Script for VMS systems to set up the
9544 configuration to build gas for VMS, and create config.status.
9545 * make-gas.com: Redone to work with new scheme.
9546 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
9548 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

9551 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
9552 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
9553 types of malformed stabs. Change parsing algorithm so that we are
9554 more certain of having all of the information that we need on hand.
9555 * obj-vms.c (final_forward_reference): New function, used to help
9556 resolve the data types of as many struct elements as possible
9557 when some part of the struct is not fully defined by the compiler.

9560 * obj-vms.c (VMS_write_object_file): Define all vtable psects
9561 as symbols as well in the object file. Look for external functions

9563 g++ compiler is incapable of doing this.
9564 * tc-vax.c: Add '1' option for backward compatibility with older GCC
9566 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
9567 * input-scrub.c (as_where): Fix bug where as would crash if we did not
9568 have the name of the source file yet.
9569 * config/ho-vms.h: define HO_VMS, not HO_VAX.
9571 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
9573 * read.c (s_data): Always use "data_section", since it'll map to
9574 SEG_DATA or SEG_E1 if needed.
9575 (s_lcomm): Likewise with bss_section.
9576 (s_fill): Use memset, not bzero.
9578 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

9600 (big_section, reg_section, pass1_section, diff_section,
9601 absent_section, text_section, data_section, bss_section): If
9602 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
9603 mapping to segT enum values.
9604 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
9605 if these are used or defined, if BFD_ASSEMBLER.
9606 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
9607 subseg_new split into two functions.
9608 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
9610 * as.h (volatile): Don't define if already defined.
9611 (had_errors, had_warnings): Provide prototypes for ANSI C even if
9613 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
9614 declare with format attribute for -Wformat checking.
9616 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
9618 * app.c, config/tc-*.c: Don't include read.h, since it is already
9621 * These are based on patches from Minh Tran-le
9622 <mtranle@paris.intellicorp.com>.
9623 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
9624 obj_format coffbfd and gas_target i386coff for target.
9625 (i[34]86-*-isc*): New host (uses sysv).
9626 * config/i386aix.mt: Removed (no longer used).
9627 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
9629 (LDFLAGS): Added, defined as -shlib.
9630 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
9631 * config/te-sco386.h (LOCAL_LABEL): Don't define.
9632 (DOT_LABEL_PREFIX): Define.
9633 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
9634 name rather than L0\001.
9635 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
9637 * symbols.c, symbols.h (local_bss_counter): Removed.

9646 (size_section): Restored sanity check.
9647 (do_relocs_for): Base section address on s_paddr rather than
9648 computing it. Adjust a29k R_IHIHALF special case to account for
9649 section paddr (used to require paddr to be zero). If there are no
9650 reclos, set s_relptr to 0. Set relocation size in object_headers.
9651 (fill_section): Always set s_vaddr here, removing
9652 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
9653 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
9654 Set STYP_INFO for .comment.
9655 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
9656 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

9658 H_{SET,GET}_* macros.
9659 (do_linenos_for): Set lineno size in object_headers.
9660 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
9661 set s_vaddr here. If string_byte_count remains 4, set it back to
9662 0, and only write strings out if there are some. Call
9663 fill_section before do_relocs_for and do_linenos_for.
9664 (obj_coff_section): Handle optional quoted second argument giving
9665 section characteristics.
9666 (obj_coff_bss): Added to handle .bss.
9667 (obj_coff_ident): Added to handle .ident (puts string in .comment

9687 (do_scrub_next_char): For \", return " not '.
9688 (symbol_chars): Now const.
9690 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
9691 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
9693 * config/obj-coff.h: Don't use #elif.
9695 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
9696 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
9698 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
9700 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

9720 SEG_BSS, fill with NOP_OPCODE.
9721 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
9722 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
9723 using ZERO_BASED_SEGMENTS.
9724 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
9725 never set segment address for SEG_E2 (.bss) and don't write out
9726 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
9727 (obj_coff_endef): Don't merge labels or symbols awaiting forward
9728 definitions, and don't merge tags with non-tags. Check for .bf
9729 rather than just checking whether the second character is b and
9730 the third character is f.
9731 (obj_coff_val): gcc can generate values which we don't handle
9732 correctly; discard information for now, since it only affects the
9733 debugging information.
9734 (tag_find_or_name): Don't insert tags in the symbol table.
9735 (yank_symbols): Don't merge labels.
9736 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

9756 power-of-two alignment for .align.
9758 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
9759 and leave everything else alone.

9887 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
9890 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)

10000 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
10001 #elif, since it is not supported by old compilers.
10002 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
10003 couple of expressions in tc-m68k.c.
10005 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10007 * read.c (cons): If NO_RELOC is defined, use it.

10014 local labels to start with a .) and set REGISTER_PREFIX to %.
10015 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
10017 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

10028 * listing.c (debugging_pseudo): Add stabs and stabn as things to
10031 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
10033 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
10034 sections starting from zero, rather than making them consecutive.
10035 This makes subsequent reloc calculations easier, esp if the object
10036 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
10037 allocate lcomm in .data rather than in .bss. It seems that some
10038 tools can't cope with a non-zero sized bss before linkage.

10042 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10043 throughout. That enum no longer means what we thought it meant.

10046 "-mno-688[58]1" options.
10048 * tc-m68k.c: Added CPU32 support.
10050 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

10061 * Makefile.in (install): if $(tooldir) exists, install as in
10064 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10066 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10067 .word is < -32768 or > 32767. The -J flag causes the error to be
10068 ignored. This is to catch over-sized switches generated by gcc on
10069 systems which don't support the broken .word hack.
10070 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10071 write.c (fixup_segment): check for signed .word overflow if
10072 WARN_SIGNED_OVERFLOW_WORD.
10074 * write.c (fixup_segment): fixed missing parens in expression
10075 checking for byte or word overflow.
10077 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

10091 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
10093 * input-scrub.c (input_scrub_push): call input_file_begin, not
10095 messages.c (as_perror): print ": " between the passed in error and
10096 the strerror, like perror does.

10105 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
10106 Motorola and MIT syntax; gas can now assemble either type of
10108 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
10109 From Steve Chamberlain:
10110 m68kcoff.mt: for m68k COFF.
10111 obj-coffbfd.c: (fixup_mdeps) added
10112 (size_section) removed bad sanity check
10113 (fill_section) added rs_machine_dependent case
10114 (write_object_file) call fixup_mdeps
10115 (fixup_segment) set fx_subsy to 0.
10116 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
10118 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
10121 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

10145 tc-i960.c (md_ri_to_chars): Always output bout object file in
10146 little endian byte order (used to use endianness of host).
10148 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10150 * config/tc-m68k.c (init_table): Now const. Always include 68851
10151 data, so that "bc" is available to 68040 cache instructions.
10152 Added "tt0", "tt1", and 68ec030 variants.
10153 (md_assemble): Complain if 68000 (only) and 68881 are specified.
10154 (enum _register): Added TT0, TT1.
10155 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
10156 line number correctly in "internal error" messages. Don't print
10157 architecture-mismatch message for operand errors.
10159 From Colin Smith (colin@wrs.com):
10160 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

10173 one element of a family.
10175 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
10177 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
10178 so that we can assemble hand-written libgcc code.
10180 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10182 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
10183 has already been formatted (but may still contain %-characters).
10184 (as_bad): Likewise.
10186 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
10188 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
10189 written with indirection on the last two operands, which can be
10190 either data or address registers. Added a new operand type 'r'
10191 which accepts either register type. Added '(' to notend stuff in
10192 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
10194 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
10196 * as.h (enum _relax_state): Start off at one, not zero, to better
10197 catch uninitialized-variable errors.
10198 (linkrelax): Declare new variable.
10200 * messages.c (warning_count, error_count): Default initializer is
10203 * write.c: Merged some declarations, using PARMS macro.

10205 data_last_frag): No longer static.
10206 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
10207 defined, call it. Change segments before calling fixup_segment.
10208 (relax_align): If linkrelax, provide extra padding.

10238 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
10239 being used with args swapped, causing occasional lossage when
10240 refilling buffers after an include file.
10242 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
10244 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
10245 version. Discard bogus DONTDEF version.

10250 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
10251 selected architecture, print a message saying so and listing what

10303 (md_assemble): If no CPU has been set (even if FPU/PMMU
10304 characteristics have been), default to 68020. Don't need extra
10305 quotes around error string.

10443 * Makefile.in (install): Install into $(tooldir)/bin, since that's
10444 where gcc looks for it.
10446 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
10448 * Makefile.in: Changed some lines to be less confusing for some

10478 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
10480 * configure.in: vxworks68 gets te-sun3.h.
10482 * expr.c: remove limitation that local_labels_dollar or
10483 local_labels_fb must be < 10.
10485 * symbols.c: remove local_labels_dollar, replace with a function
10486 interface for a sparse array. All users adjusted.
10488 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
10490 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

10514 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
10516 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
10518 * expr.c (operand): if can't work out what sort of operand it is,
10519 then look through FLT_CHARS for a hint.
10521 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
10523 * Makefile.in, configure.in: removed traces of namesubdir,
10524 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10525 copyrights to '92, changed some from Cygnus to FSF.
10527 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
10528 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10529 copyrights to '92, changed some from Cygnus to FSF.
10531 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10533 * expr.c: If an expression is single comma, then return with
10534 SEG_ABSENT rather than an error - since the sparc front end does
10535 really strange things with things like fbge,a
10537 * as.h: include bfd.h if using many sections
10538 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
10539 local labels didn't work.
10540 * listing.c (list_symbol_table): don't core dump when there's no
10542 * write.c, write.h: call fix_new with the right number of args on
10544 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
10547 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10549 * app.c: MRI compatibility - allow single quote to start a string.
10550 * as.c: fix typo recently introduced.
10551 * as.h : Don't include aout/reloc.h - it's not right for COFF!
10552 * expr.c: Much rewriting, to accomodate MRI syntax for
10553 expressions. Also easier to read now.
10554 * listing.c: Put back defuns
10555 * read.c: modified to accept MRI syntax, put back listing pseudo
10556 ops so that an assembler built with NO_LISTING ignores list ops
10558 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
10559 machine is a SPARC or a 29K.
10560 * config/obj-aout.c: added s_sect pseudo op
10561 * config/obj-coffbfd.c: lints, set the filehdr flags right and
10562 fill in the timestamp.
10563 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
10564 anymore, define all the relocs which the tc-<x> bit will use so we
10565 can translate from them to the coff types.
10566 * config/tc-a29k.c: reloc_type isn't ane enum any more
10567 * config/tc-m68k.c: Added NO_RELOC definition.
10569 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10571 * Makefile.in: put header files before C source for TAGS; remove
10572 references to non-existent syscalls.h.
10574 * read.c, write.c subsegs.c: back out the .bss changes.
10576 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
10578 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
10580 * a.out.h: removed.
10582 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
10584 * symbols.c (local_label_name): symbols now start with ^A.
10586 * read.c, subsegs.c, write.c obj-coff.c: added handling of
10587 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
10588 generate these sections. .align: will use NOP_OPCODE or 0
10589 for padding. This is just for being nice to the
10592 * expr.c (operand): changed to generate local label "\001L0"
10593 starting with a ^A so that it is recognized as a local label.
10595 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
10597 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
10598 i/o opcodes - inb, inw, outb and outw. string manipulation with
10599 att syntax - scmp, slod, smov, ssca, ssto.
10601 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
10602 to just after .file .
10604 In obj_crawl_symbol_chain() where it tries to put the external
10605 symbols apart, with the condition:
10606 (!S_IS_DEFINED(symbolP) &&
10607 !S_IS_DEBUG(symbolP) &&
10608 !SF_GET_STATICS(symbolP))
10609 it was moving too many symbols out. So I switch it back to the
10611 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
10613 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
10614 so that we don't use the F_RELFLG which make the linker complain
10615 that somebody has stripped the relocation info.
10617 Also, the AIX ld program require that the relocation table
10618 is sorted by r_vaddr like the standard ATT assembler does.
10620 [he also changed the sizeof(struct ...)'s into the coff
10621 style FOOSZ macros. I'm not sure this is right, but I can't
10622 remember why. xoxorich.]
10624 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
10626 * Makefile.in, configure.in, doc: use the doc. Build it, install
10629 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
10631 * read.c: white space and comments only.
10633 * configure.in: use the new atof-ns32.c for ns32k.
10635 * write.c: comment change only.
10637 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
10638 aren't yet integrated.
10640 * tc-i860.[hc]: blew off the dust. Something must still be done
10641 about conflicting relocation types.
10643 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
10646 * tc-i960.c, tc-sparc.c: white space and comments only.
10648 * tc-a29k.h: delete duplicate macro definition.
10650 * new file atof-ns32k.c copied from hack's last unreleased gas.
10652 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
10654 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
10657 * nearly everything. flush ChangeLog, package as gas-1.92.1.
10658 ChangeLog's prior to this are sketchy at best. I have logs.
10659 They just aren't ChangeLogs.
