34 also before setting STYP_NOLOAD for .bss section.
36 * config/tc-m68k.c (flag_reg_prefix_optional): New variable.

53 * config/tc-m68k.c (DATA, ADDR, SP, FPREG, COPNUM, BAD, BAC):
54 Define as macros instead of enumerators, since the Apollo compiler
55 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum

62 [TE_APOLLO] (OBJ_COFF_OMIT_OPTIONAL_HEADER): Undefine. That is,
63 do include the optional header for Apollo target.
64 (COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
66 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
67 can be used within a label name.
69 * config/tc-m68k.h (m68k_init_after_args): Declare.

93 * listing.c (list_symbol_table): Don't print register symbols as
96 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip

98 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
100 * as.c (main): If tc_init_after_args is defined, invoke it after
101 all arguments have been processed.

104 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
105 section instead of .text. Call create_target_segments.

110 * config/tc-mips.c (append_insn): Permit branches to be switched
111 with the preceding instruction even if .set nobopt has been seen.
112 .set nobopt actually controls whether to bring up an instruction
113 from the branch target, which gas does not currently support.

178 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
180 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
182 * vmsconf.sh: In generated file, get ".obj" suffix right, build
183 source files from other directories into objects in the current
184 directory, and specify PSECT attributes explicitly to linker.
185 Also added missing label.
186 * Makefile.in (stamp-mk.com): Reference new variable
187 VMS_OTHER_OBJS for list of non-local object files, instead of

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

274 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
275 don't spew remainder of input file in error message.
276 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
277 message with reloc type and try to process remainder of file.
279 * doc/Makefile.in (install-info-as, install-info-gasp): New
280 targets, now explicitly checking $(srcdir) for info files.
281 (install-info): Depend on both of them; do nothing more.

285 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
287 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
289 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
290 flag rather than signedp field. Only permit extended range if
291 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
292 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
294 * config/tc-ppc.c (ppc_size): New static variable.
295 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
296 (md_begin): If an instruction has a size specific flag set, only

299 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
301 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
302 cross section PC relative relocs right for COFF and ELF.
304 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
306 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

317 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
318 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
319 and -many (all architectures).

330 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
332 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
333 branch with an instruction that uses $at, in case the branch is
335 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
336 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
337 to make it pcrel_offset.
338 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
339 reloc->address; another gruesome hack to get gas reloc handling to
342 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
344 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using

348 (md_assemble): Call it.
349 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
351 (lituse_pending): New variable. Set by anything that generates a
352 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
353 tested by code that might want to emit a LITUSE reloc.
354 (emit_unaligned_io): New function. Currently calls md_assemble,
355 but it should eventually be converted to generate the insn itself
356 and call emit_insn directly.
357 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
358 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
359 emit_bis_r): Likewise.

366 the value can't be resolved.
368 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
370 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
371 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

387 (load_address): Handle EMBEDDED_PIC.
388 (macro): Handle EMBEDDED_PIC in all PIC cases.
389 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
390 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
391 -non_shared to use NO_PIC (this is how the Irix 5 assembler
392 works). Do not permit -G with SVR4_PIC.
393 (s_abicalls): Warn if -G was used, and force -G 0.
394 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
395 anything but a.out, not just for ELF. For ECOFF, don't generate a
396 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
398 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.

406 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
408 * Makefile.in (config-stamp): If `defs' is defined, emit a
409 preprocessor directive to create a macro named by this value into
410 config.new; don't explicitly go for BFD_ASSEMBLER.
411 * configure.in: Define `defs', not `BFDDEF'. Set it to
412 MANY_SEGMENTS for any obj-coffbfd target.
413 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
414 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
416 (LOCAL_LOADLIBES): Deleted.
417 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
418 * config/m88kcoff.mt (TDEFINES): Ditto.

444 bfd_set_symtab is called.
445 (dump_section_relocs): Note whether a symbol is a section symbol
447 (adjust_reloc_syms): For now, always supply an absolute symbol for
448 fixups without symbols but not yet `done'. Use section_symbol to
449 get the symbol, instead of going directly for abs_symbol.
450 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
451 reloc is not a section symbol and is not in the symbol table.
452 (set_symtab): New function, broken out from write_object_file.
453 Counts symbol table instead of relying on an earlier count.
454 (write_object_file): Call set_symtab, but do it after potentially
455 invoking the *_frob_file macros. Don't bother counting symbols.
456 Call symbol_remove, instead of expanding it in place. Moved the
457 conditionalized `object_file_size' declaration down to
458 conditionalized block where it's used. When using the absolute
459 symbol for a fixup without a symbol, set sy_used_in_reloc.
460 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
461 the correct symbol for the absolute section.
463 * subsegs.c (section_symbol): Use symbol_new instead of
464 symbol_make, since we may want it to go into the symbol table.
465 Make the new symbol have internal linkage. If
466 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
467 symbol with the newly created GAS symbol.
468 (obj_sec_sym_ok_for_reloc): Default to always returning 0.

2339 pass new argument for i, j and o cases.
2340 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2561 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2562 the table, require that the one without bit 0x1000000 set come

2617 * write.c (write_relocs): For relocs that are pc_relative and
2618 pcrel_offset and not partial_inplace, adjust reloc->addend to

2674 for keeping or rejecting configurations still under development;
2675 default is to assume production environment, and reject configs
2676 still being worked on. Mark Elf configurations (except sparc and
2677 i386) as developmental. Deleted cases matching some generic names
2678 in favor of more specific names. (E.g., when we get Alpha

2695 through inclusion of tc-hppa.h. Delete all forward declarations
2696 for functions only used within tc-hppa.c, likewise for structures,
2697 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2698 conditional code in a few small places.
2700 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2701 structures, global variables, forward declarations together.

2703 conditional code -- try to group conditional code together
2704 into a few places. Make all functions and variables which
2705 are only used within tc-hppa.c static. PARAMize all functions.
2706 Add comments to functions. Delete unused functions, variables,
2707 #defines, etc. Delete unused members within structures. Delete
2708 ldil;ble hacks -- it is believed they were installed to work
2709 around old gas bugs. Avoid using mixed case for local
2710 functions, variables, and structures. Fix formatting problems
2711 not found by GNU-indent. Add FIXME notices for things which
2712 should be worked on the near future. Delete lots of old
2713 useless (1.36 PA-SOM) code.

2786 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2788 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2789 ELF, since the ELF object format does not have these type of
2790 relocations. Change the abort into as as_bad and return
2791 BFD_RELOC_NONE to silence compiler warnings.
2792 (md_assemble): Keep track of the instruction size. Allow white
2793 space between the $ and the constant for compatibility with older
2794 gases and other assemblers.
2795 (i386_operand): Skip spaces between $ and expression.

3791 are also magic, and have special default flag settings.
3792 (obj_elf_frob_symbol): Since the return value from this function

3856 * Extensive changes to permit symbols to contain any expression
3857 type and to delay the computation of the expression until the
3858 value is actually needed. This permits setting symbols to values
3859 calculated based on object code size. Expressions were changed to
3860 no longer be in a section, to stop the overloading of segment and
3861 expression type that previously occurred.
3863 * as.c (big_section, pass1_section, diff_section, absent_section):
3865 (expr_section): Added (used for dummy symbols which hold

5228 dropping a space immediately following an identifier.
5229 * expr.c, write.c: Rewrote assert expressions to not use multiple
5230 lines; I don't think that can be done portably.
5231 * config/tc-mips.c (macro): Use $AT if target register is zero in
5232 load instruction, which it can be for a floating point load.
5234 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5306 prototypes for all static functions. Moved existing minimal
5307 debugging format support info #ifndef OBJ_ECOFF blocks.

5358 * read.c (s_ignore): Don't declare is_end_of_line. It's
5359 redundant, and triggers a VMS gcc compiler bug.
5361 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5362 current segment as an argument. (Ignored in all cases but VMS.)
5363 All callers and definitions changed.

5659 * config/tc-sparc.c (architecture_requested, warn_on_bump,
5660 md_relax_table): Use default zero initialization.
5661 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5662 latter, instead of selecting with preprocessor conditionals.
5664 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5666 * configure.in: recognise all sparclite variants
5668 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

5671 accidentally changed to use subseg_change where it should have
5674 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5676 * expr.c (operand): If character other than comma or newline is a
5677 logical end-of-line character, use the newline case.
5678 From Eric Youngdale:
5679 (operand): Set X_add_number field for floating-point numbers.
5680 (operand): Treat zero byte as end-of-operand.
5682 * configure.in (per-target): Look for with_bfd_assembler option.
5683 For now, only accept "no", until the merge is done.
5685 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5686 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5687 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5688 * read.c: Finish conversion to S_* macros in the VMS only
5689 parts of the program. Add "const" modifier to hex_value.
5690 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5692 * expr.c: Add "const" modifier to hex_value.
5693 * symbols.c: Finish conversion to S_* macros in the VMS only
5694 parts of the program. Add "const" modifier to
5695 md_[long,short]_jump_size. Remove declaration of const_flag
5696 (which will be declared in obj-vms.h).
5697 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5698 Fix arguments to VMS_write_object_file.
5699 * config-gas.com: New file. Script for VMS systems to set up the
5700 configuration to build gas for VMS, and create config.status.
5701 * make-gas.com: Redone to work with new scheme.
5702 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5704 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5705 will swap bytes if needed on a big endian system. Use throughout
5707 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5708 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5709 types of malformed stabs. Change parsing algorithm so that we are
5710 more certain of having all of the information that we need on hand.
5711 * obj-vms.c (final_forward_reference): New function, used to help
5712 resolve the data types of as many struct elements as possible
5713 when some part of the struct is not fully defined by the compiler.
5714 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5716 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5717 as symbols as well in the object file. Look for external functions
5718 that start with "__vt.", and turn them into variables, since the
5719 g++ compiler is incapable of doing this.
5720 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5722 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5723 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5724 have the name of the source file yet.
5725 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5727 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5729 * read.c (s_data): Always use "data_section", since it'll map to
5730 SEG_DATA or SEG_E1 if needed.
5731 (s_lcomm): Likewise with bss_section.
5732 (s_fill): Use memset, not bzero.
5734 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
5736 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

5750 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
5751 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

5755 (section_alignment): Declare only if not BFD_ASSEMBLER.
5756 (big_section, reg_section, pass1_section, diff_section,
5757 absent_section, text_section, data_section, bss_section): If
5758 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5759 mapping to segT enum values.
5760 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5761 if these are used or defined, if BFD_ASSEMBLER.
5762 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5763 subseg_new split into two functions.
5764 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5766 * as.h (volatile): Don't define if already defined.
5767 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5769 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5770 declare with format attribute for -Wformat checking.
5772 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5774 * app.c, config/tc-*.c: Don't include read.h, since it is already
5777 * These are based on patches from Minh Tran-le
5778 <mtranle@paris.intellicorp.com>.
5779 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5780 obj_format coffbfd and gas_target i386coff for target.
5781 (i[34]86-*-isc*): New host (uses sysv).
5782 * config/i386aix.mt: Removed (no longer used).
5783 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5785 (LDFLAGS): Added, defined as -shlib.
5786 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5787 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5788 (DOT_LABEL_PREFIX): Define.
5789 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5790 name rather than L0\001.
5791 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5793 * symbols.c, symbols.h (local_bss_counter): Removed.
5794 * write.c (write_object_file): bss no longer uses
5795 local_bss_counter. Pass correct data and bss size to
5796 VMS_write_object_file.

5801 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
5802 (size_section): Restored sanity check.
5803 (do_relocs_for): Base section address on s_paddr rather than
5804 computing it. Adjust a29k R_IHIHALF special case to account for
5805 section paddr (used to require paddr to be zero). If there are no
5806 reclos, set s_relptr to 0. Set relocation size in object_headers.
5807 (fill_section): Always set s_vaddr here, removing
5808 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5809 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5810 Set STYP_INFO for .comment.
5811 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5812 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5814 H_{SET,GET}_* macros.
5815 (do_linenos_for): Set lineno size in object_headers.
5816 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5817 set s_vaddr here. If string_byte_count remains 4, set it back to
5818 0, and only write strings out if there are some. Call
5819 fill_section before do_relocs_for and do_linenos_for.
5820 (obj_coff_section): Handle optional quoted second argument giving
5821 section characteristics.
5822 (obj_coff_bss): Added to handle .bss.
5823 (obj_coff_ident): Added to handle .ident (puts string in .comment
5825 (obj_coff_lcomm): Put common symbols in .bss, not .data.
5826 (fixup_mdeps): Change to segment. Call frag_wane after
5828 (fixup_segment): Explicitly check S_IS_COMMON before making 386
5829 adjustment (already happened only for common symbols, but this is
5831 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
5832 * config/tc-i386.c (s_bss): Don't use if I386COFF.

5843 (do_scrub_next_char): For \", return " not '.
5844 (symbol_chars): Now const.
5846 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5847 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5849 * config/obj-coff.h: Don't use #elif.
5851 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5852 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5854 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

5876 SEG_BSS, fill with NOP_OPCODE.
5877 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
5878 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5879 using ZERO_BASED_SEGMENTS.
5880 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5881 never set segment address for SEG_E2 (.bss) and don't write out
5882 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5883 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5884 definitions, and don't merge tags with non-tags. Check for .bf
5885 rather than just checking whether the second character is b and
5886 the third character is f.
5887 (obj_coff_val): gcc can generate values which we don't handle
5888 correctly; discard information for now, since it only affects the
5889 debugging information.
5890 (tag_find_or_name): Don't insert tags in the symbol table.
5891 (yank_symbols): Don't merge labels.
5892 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6074 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6075 constant will not fit in an immediate field.
6076 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

6111 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6113 * Support for i386-sysv.
6114 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
6115 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
6116 be used to set them all to zero as was done before.
6117 (fill_section): segment addresses now set in write_object_file.
6118 (fill_section): Don't set STYP_NOLOAD for .bss section.
6119 (fixup_segment): 386 uses strange common symbol format.
6120 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
6121 compatibility with SVR3.2 linker.
6122 * configure.in: i386-sysv and i386-sco use coffbfd.

6134 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
6135 support for C source listings. (obj_coff_endef): look in the right
6136 part of the symbol for the symbol name
6138 * tc-m68k.c (get_num): make it work for all segments, not just the
6141 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

6152 * tc-z8k.c: lots of bug fixes
6154 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6156 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6157 #elif, since it is not supported by old compilers.
6158 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6159 couple of expressions in tc-m68k.c.
6161 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6163 * read.c (cons): If NO_RELOC is defined, use it.
6165 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6167 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6169 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6170 local labels to start with a .) and set REGISTER_PREFIX to %.
6171 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

6189 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6190 sections starting from zero, rather than making them consecutive.
6191 This makes subsequent reloc calculations easier, esp if the object
6192 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6193 allocate lcomm in .data rather than in .bss. It seems that some
6194 tools can't cope with a non-zero sized bss before linkage.
6196 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6198 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

6220 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6222 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6223 .word is < -32768 or > 32767. The -J flag causes the error to be
6224 ignored. This is to catch over-sized switches generated by gcc on
6225 systems which don't support the broken .word hack.
6226 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6227 write.c (fixup_segment): check for signed .word overflow if
6228 WARN_SIGNED_OVERFLOW_WORD.

6247 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6249 * input-scrub.c (input_scrub_push): call input_file_begin, not
6251 messages.c (as_perror): print ": " between the passed in error and
6252 the strerror, like perror does.
6254 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

6257 From Steve Chamberlain:
6258 Makefile.in: Handle m68*-*-coff*.
6259 read.c, read.h: add mult argument to s_space
6261 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6262 Motorola and MIT syntax; gas can now assemble either type of
6264 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6272 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6274 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6277 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6279 * Makefile.in (LIBS): Include opcode library.

6304 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6306 * config/tc-m68k.c (init_table): Now const. Always include 68851
6307 data, so that "bc" is available to 68040 cache instructions.
6308 Added "tt0", "tt1", and 68ec030 variants.
6309 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6310 (enum _register): Added TT0, TT1.
6311 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6312 line number correctly in "internal error" messages. Don't print
6313 architecture-mismatch message for operand errors.

6338 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6339 has already been formatted (but may still contain %-characters).
6342 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6344 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6345 written with indirection on the last two operands, which can be
6346 either data or address registers. Added a new operand type 'r'
6347 which accepts either register type. Added '(' to notend stuff in
6348 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6588 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6590 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
6592 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6594 * write.c (write_object_file): For b.out format, round up section
6595 start addresses to match required alignment.
6597 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6599 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6600 where gcc looks for it.
6602 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6604 * Makefile.in: Changed some lines to be less confusing for some
6607 * input-file.c: Conditionalize on _IOFBF, not VMS.
6609 * read.c, write.c: Change a series of ifdef/elif to
6610 ifdef/else/ifdef etc.
6612 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
6614 * symbols.c (fb_label_init): fix sizeof to memset.
6616 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
6618 * Makefile.in: install the man page.
6620 * Makefile.in: pass down MAKEINFO explicitly on info.
6622 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
6624 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6626 * flonum-const.c: renamed flonum-konst.c to stop dos name
6629 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
6631 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
6632 tc-m68k.h to te-sun3.h.
6634 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
6636 * configure.in: vxworks68 gets te-sun3.h.
6638 * expr.c: remove limitation that local_labels_dollar or
6639 local_labels_fb must be < 10.
6641 * symbols.c: remove local_labels_dollar, replace with a function
6642 interface for a sparse array. All users adjusted.
6644 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
6646 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6648 * doc/Makefile.in: commented out line for building as-all.texinfo.
6651 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
6653 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
6655 * Makefile.in: added check target.
6657 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6659 * Makefile.in: added tooldir and program_prefix.
6661 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
6663 * write.{c,h} (fix_new): Make these declarations consistent.
6665 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
6667 * Makefile.in (strerror.o): Add rule so that broken Sun make can
6670 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6672 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6674 * expr.c (operand): if can't work out what sort of operand it is,
6675 then look through FLT_CHARS for a hint.
6677 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6679 * Makefile.in, configure.in: removed traces of namesubdir,
6680 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6681 copyrights to '92, changed some from Cygnus to FSF.
6683 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6684 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6685 copyrights to '92, changed some from Cygnus to FSF.
6687 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6689 * expr.c: If an expression is single comma, then return with
6690 SEG_ABSENT rather than an error - since the sparc front end does
6691 really strange things with things like fbge,a
6693 * as.h: include bfd.h if using many sections
6694 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6695 local labels didn't work.
6696 * listing.c (list_symbol_table): don't core dump when there's no
6698 * write.c, write.h: call fix_new with the right number of args on
6700 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6703 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6705 * app.c: MRI compatibility - allow single quote to start a string.
6706 * as.c: fix typo recently introduced.
6707 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6708 * expr.c: Much rewriting, to accomodate MRI syntax for
6709 expressions. Also easier to read now.
6710 * listing.c: Put back defuns
6711 * read.c: modified to accept MRI syntax, put back listing pseudo
6712 ops so that an assembler built with NO_LISTING ignores list ops
6714 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6715 machine is a SPARC or a 29K.
6716 * config/obj-aout.c: added s_sect pseudo op
6717 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6718 fill in the timestamp.
6719 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6720 anymore, define all the relocs which the tc-<x> bit will use so we
6721 can translate from them to the coff types.
6722 * config/tc-a29k.c: reloc_type isn't ane enum any more
6723 * config/tc-m68k.c: Added NO_RELOC definition.
6725 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6727 * Makefile.in: put header files before C source for TAGS; remove
6728 references to non-existent syscalls.h.
6730 * read.c, write.c subsegs.c: back out the .bss changes.
6732 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6734 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6738 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6740 * symbols.c (local_label_name): symbols now start with ^A.
6742 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6743 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6744 generate these sections. .align: will use NOP_OPCODE or 0
6745 for padding. This is just for being nice to the
6748 * expr.c (operand): changed to generate local label "\001L0"
6749 starting with a ^A so that it is recognized as a local label.
6751 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6753 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6754 i/o opcodes - inb, inw, outb and outw. string manipulation with
6755 att syntax - scmp, slod, smov, ssca, ssto.
6757 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6758 to just after .file .
6760 In obj_crawl_symbol_chain() where it tries to put the external
6761 symbols apart, with the condition:
6762 (!S_IS_DEFINED(symbolP) &&
6763 !S_IS_DEBUG(symbolP) &&
6764 !SF_GET_STATICS(symbolP))
6765 it was moving too many symbols out. So I switch it back to the
6767 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6769 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6770 so that we don't use the F_RELFLG which make the linker complain
6771 that somebody has stripped the relocation info.
6773 Also, the AIX ld program require that the relocation table
6774 is sorted by r_vaddr like the standard ATT assembler does.
6776 [he also changed the sizeof(struct ...)'s into the coff
6777 style FOOSZ macros. I'm not sure this is right, but I can't
6778 remember why. xoxorich.]
6780 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6782 * Makefile.in, configure.in, doc: use the doc. Build it, install
6785 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6787 * read.c: white space and comments only.
6789 * configure.in: use the new atof-ns32.c for ns32k.
6791 * write.c: comment change only.
6793 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6794 aren't yet integrated.
6796 * tc-i860.[hc]: blew off the dust. Something must still be done
6797 about conflicting relocation types.
6799 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6802 * tc-i960.c, tc-sparc.c: white space and comments only.
6804 * tc-a29k.h: delete duplicate macro definition.
6806 * new file atof-ns32k.c copied from hack's last unreleased gas.
6808 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6810 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6813 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6814 ChangeLog's prior to this are sketchy at best. I have logs.
6815 They just aren't ChangeLogs.
6819 version-control: never
