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

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

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

159 * as.c (main): If tc_init_after_args is defined, invoke it after
160 all arguments have been processed.

232 * expr.c (operand): Try to parse "0f" and "0b" sequences as
233 floating point and binary numbers respectively; if it doesn't
234 work, treat them as local labels.
236 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
237 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
239 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
241 * vmsconf.sh: In generated file, get ".obj" suffix right, build
242 source files from other directories into objects in the current
243 directory, and specify PSECT attributes explicitly to linker.
244 Also added missing label.
245 * Makefile.in (stamp-mk.com): Reference new variable
246 VMS_OTHER_OBJS for list of non-local object files, instead of

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

334 don't spew remainder of input file in error message.
335 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
336 message with reloc type and try to process remainder of file.

392 branch with an instruction that uses $at, in case the branch is
394 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.

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

411 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
412 tested by code that might want to emit a LITUSE reloc.

429 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
430 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

450 -non_shared to use NO_PIC (this is how the Irix 5 assembler
451 works). Do not permit -G with SVR4_PIC.

471 MANY_SEGMENTS for any obj-coffbfd target.
472 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
473 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
475 (LOCAL_LOADLIBES): Deleted.
476 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
477 * config/m88kcoff.mt (TDEFINES): Ditto.

503 bfd_set_symtab is called.
504 (dump_section_relocs): Note whether a symbol is a section symbol
506 (adjust_reloc_syms): For now, always supply an absolute symbol for
507 fixups without symbols but not yet `done'. Use section_symbol to
508 get the symbol, instead of going directly for abs_symbol.
509 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
510 reloc is not a section symbol and is not in the symbol table.
511 (set_symtab): New function, broken out from write_object_file.
512 Counts symbol table instead of relying on an earlier count.
513 (write_object_file): Call set_symtab, but do it after potentially
514 invoking the *_frob_file macros. Don't bother counting symbols.
515 Call symbol_remove, instead of expanding it in place. Moved the
516 conditionalized `object_file_size' declaration down to
517 conditionalized block where it's used. When using the absolute
518 symbol for a fixup without a symbol, set sy_used_in_reloc.
519 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
520 the correct symbol for the absolute section.
522 * subsegs.c (section_symbol): Use symbol_new instead of
523 symbol_make, since we may want it to go into the symbol table.
524 Make the new symbol have internal linkage. If
525 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
526 symbol with the newly created GAS symbol.
527 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
528 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

533 (in_signed_range): New function.
535 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
536 (sparc_ip, label "immediate"): Reject constants for pcrel
537 instructions only if the relocation type indicates a "call"
538 instruction and the offset is within range of a "jmpl %g0". If
539 it's not in range, use the absolute section symbol plus an offset.
540 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
542 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
544 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
547 * configure.in: Eliminated all targets using obj-coff but not
548 defining BFD_ASSEMBLER; I think all such targets that are
549 supported will be matched by real CPU-OS combinations earlier in
551 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
552 some comments about the dpx2 configuration, but left it disabled,
553 since it couldn't be reached before.
554 (target a29k-amd-ebmonold): Deleted.
556 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

564 the 'j' operand if there are no further alternatives for this
567 * config/obj-coffbfd.c (adjust_stab_section): Initialize
568 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
569 is not SEG_UNKNOWN rather than checking whether it is >= 0.
571 * config/tc-mips.c (mips_align): Take new argument, label, and use
572 it instead of global insn_label.
573 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
574 call to mips_emit_delay and pass it to mips_align.
576 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
578 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
580 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
581 argument to a .callinfo directive. Don't loop forever on errors.
583 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
584 use pre-defined registers as arguments.

592 version number. Delete all versions of temp files when finished
593 with them. Create config.h.
595 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
596 values to reduce number of lookups with S_GET_VALUE. Skip debug

598 holger@botbso.rhein-main.de.)
599 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
600 field. (Also from Holger Teutsch.) Watch for a would-be register
601 mask that spans frags.
603 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
604 this_base, not line_base. (Patch from Andreas Arens,
605 ari@obelix.av.rwth-aachen.de.)
607 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
608 look local if they're exported or undefined. Used to be done for

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

2765 Add comments to functions. Delete unused functions, variables,
2766 #defines, etc. Delete unused members within structures. Delete
2767 ldil;ble hacks -- it is believed they were installed to work
2768 around old gas bugs. Avoid using mixed case for local
2769 functions, variables, and structures. Fix formatting problems
2770 not found by GNU-indent. Add FIXME notices for things which
2771 should be worked on the near future. Delete lots of old

3915 * Extensive changes to permit symbols to contain any expression
3916 type and to delay the computation of the expression until the
3917 value is actually needed. This permits setting symbols to values
3918 calculated based on object code size. Expressions were changed to
3919 no longer be in a section, to stop the overloading of segment and
3920 expression type that previously occurred.
3922 * as.c (big_section, pass1_section, diff_section, absent_section):
3924 (expr_section): Added (used for dummy symbols which hold

4124 sy_resolved and sy_resolving single bit fields.
4125 * symbols.c (symbol_new): Don't initialize sy_forward field.

5158 * as.h (const, volatile): Put these definitions back, and use
5161 * doc/as.texinfo: First pass at using new texinfo features --
5162 variables, conditional tests. Far from complete.

5190 dependencies are read, not when they are used).
5192 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
5193 a29k .bss section; the mondfe program doesn't like it.

5214 source directory, if that's not the current directory.
5216 * configure.in (per-host): Accept MIPS host with BSD version

5238 process relocs if there aren't any relocs to process. Avoids
5239 malloc/free bug on SCO too.

5242 avoid some redefinition complaints on some systems.
5243 (const, volatile): Don't need these conditionally defined if we
5244 use CONST and VOLATILE from ansidecl.h.
5245 (seg_name): Use CONST, not const.
5247 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5249 * config/tc-mips.c: Reindented to GNU standards.

5253 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5254 (fixup_segment): Add a29k special case; the linker is not prepared
5255 to see a segment offset here.
5257 * app.c (do_scrub_next_char): Added new state, 10, modifying state

5260 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5262 * Makefile.in: add dvi target; as-$(config).texinfo might live in

5278 bignums, but don't emit error message.
5280 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
5282 * Makefile.in (targ-cpu.o): Depend on config.h.
5284 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5286 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5287 dropping a space immediately following an identifier.
5288 * expr.c, write.c: Rewrote assert expressions to not use multiple
5289 lines; I don't think that can be done portably.
5290 * config/tc-mips.c (macro): Use $AT if target register is zero in
5291 load instruction, which it can be for a floating point load.
5293 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5314 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5316 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5317 to be on a single line.

5365 prototypes for all static functions. Moved existing minimal
5366 debugging format support info #ifndef OBJ_ECOFF blocks.

5415 * make-gas.com: Find obstack.obj if it's not in the current
5417 * read.c (s_ignore): Don't declare is_end_of_line. It's
5418 redundant, and triggers a VMS gcc compiler bug.
5420 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5421 current segment as an argument. (Ignored in all cases but VMS.)
5422 All callers and definitions changed.

5719 md_relax_table): Use default zero initialization.
5720 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5721 latter, instead of selecting with preprocessor conditionals.
5723 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5725 * configure.in: recognise all sparclite variants

5735 * expr.c (operand): If character other than comma or newline is a
5736 logical end-of-line character, use the newline case.
5737 From Eric Youngdale:
5738 (operand): Set X_add_number field for floating-point numbers.
5739 (operand): Treat zero byte as end-of-operand.
5741 * configure.in (per-target): Look for with_bfd_assembler option.
5742 For now, only accept "no", until the merge is done.
5744 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5745 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5751 * expr.c: Add "const" modifier to hex_value.
5752 * symbols.c: Finish conversion to S_* macros in the VMS only
5753 parts of the program. Add "const" modifier to
5754 md_[long,short]_jump_size. Remove declaration of const_flag
5755 (which will be declared in obj-vms.h).
5756 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5757 Fix arguments to VMS_write_object_file.
5758 * config-gas.com: New file. Script for VMS systems to set up the
5759 configuration to build gas for VMS, and create config.status.
5760 * make-gas.com: Redone to work with new scheme.
5761 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5763 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5764 will swap bytes if needed on a big endian system. Use throughout
5766 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5767 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5768 types of malformed stabs. Change parsing algorithm so that we are
5769 more certain of having all of the information that we need on hand.
5770 * obj-vms.c (final_forward_reference): New function, used to help
5771 resolve the data types of as many struct elements as possible
5772 when some part of the struct is not fully defined by the compiler.

5775 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5776 as symbols as well in the object file. Look for external functions
5777 that start with "__vt.", and turn them into variables, since the
5778 g++ compiler is incapable of doing this.
5779 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5781 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5782 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5783 have the name of the source file yet.
5784 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5786 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5788 * read.c (s_data): Always use "data_section", since it'll map to
5789 SEG_DATA or SEG_E1 if needed.
5790 (s_lcomm): Likewise with bss_section.
5791 (s_fill): Use memset, not bzero.
5793 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5814 (section_alignment): Declare only if not BFD_ASSEMBLER.
5815 (big_section, reg_section, pass1_section, diff_section,
5816 absent_section, text_section, data_section, bss_section): If
5817 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5818 mapping to segT enum values.
5819 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5820 if these are used or defined, if BFD_ASSEMBLER.
5821 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5822 subseg_new split into two functions.
5823 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5825 * as.h (volatile): Don't define if already defined.
5826 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5828 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5829 declare with format attribute for -Wformat checking.
5831 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5833 * app.c, config/tc-*.c: Don't include read.h, since it is already
5836 * These are based on patches from Minh Tran-le
5837 <mtranle@paris.intellicorp.com>.
5838 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5839 obj_format coffbfd and gas_target i386coff for target.
5840 (i[34]86-*-isc*): New host (uses sysv).
5841 * config/i386aix.mt: Removed (no longer used).
5842 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5844 (LDFLAGS): Added, defined as -shlib.
5845 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5846 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5847 (DOT_LABEL_PREFIX): Define.
5848 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5849 name rather than L0\001.

5852 * symbols.c, symbols.h (local_bss_counter): Removed.
5853 * write.c (write_object_file): bss no longer uses
5854 local_bss_counter. Pass correct data and bss size to
5855 VMS_write_object_file.

5861 (size_section): Restored sanity check.
5862 (do_relocs_for): Base section address on s_paddr rather than
5863 computing it. Adjust a29k R_IHIHALF special case to account for
5864 section paddr (used to require paddr to be zero). If there are no
5865 reclos, set s_relptr to 0. Set relocation size in object_headers.
5866 (fill_section): Always set s_vaddr here, removing
5867 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5868 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5869 Set STYP_INFO for .comment.

5873 H_{SET,GET}_* macros.
5874 (do_linenos_for): Set lineno size in object_headers.
5875 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5876 set s_vaddr here. If string_byte_count remains 4, set it back to
5877 0, and only write strings out if there are some. Call
5878 fill_section before do_relocs_for and do_linenos_for.
5879 (obj_coff_section): Handle optional quoted second argument giving
5880 section characteristics.
5881 (obj_coff_bss): Added to handle .bss.
5882 (obj_coff_ident): Added to handle .ident (puts string in .comment

5885 (fixup_mdeps): Change to segment. Call frag_wane after
5887 (fixup_segment): Explicitly check S_IS_COMMON before making 386
5888 adjustment (already happened only for common symbols, but this is
5890 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

5902 (do_scrub_next_char): For \", return " not '.
5903 (symbol_chars): Now const.
5905 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5906 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5908 * config/obj-coff.h: Don't use #elif.
5910 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5911 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5913 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5915 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5929 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
5931 * listing.c: Call xmalloc, not malloc; don't declare malloc.
5933 * Changes to support SCO 3.2v4:

5935 SEG_BSS, fill with NOP_OPCODE.
5936 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
5937 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5938 using ZERO_BASED_SEGMENTS.
5939 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5940 never set segment address for SEG_E2 (.bss) and don't write out
5941 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5942 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5943 definitions, and don't merge tags with non-tags. Check for .bf
5944 rather than just checking whether the second character is b and
5945 the third character is f.
5946 (obj_coff_val): gcc can generate values which we don't handle
5947 correctly; discard information for now, since it only affects the
5948 debugging information.
5949 (tag_find_or_name): Don't insert tags in the symbol table.
5950 (yank_symbols): Don't merge labels.
5951 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6097 could be doing emulation.
6099 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6102 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6129 consistently const, and always initialized them. Included read.h.
6131 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6133 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6134 constant will not fit in an immediate field.
6135 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
6137 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

6154 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
6155 so widening works consistently.
6157 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
6159 * version.c: Put conditional "const" before version_string, not

6170 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6172 * Support for i386-sysv.
6173 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
6174 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
6175 be used to set them all to zero as was done before.

6177 (fill_section): Don't set STYP_NOLOAD for .bss section.
6178 (fixup_segment): 386 uses strange common symbol format.

6215 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6216 #elif, since it is not supported by old compilers.
6217 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6218 couple of expressions in tc-m68k.c.
6220 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6222 * read.c (cons): If NO_RELOC is defined, use it.
6224 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6226 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6228 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6229 local labels to start with a .) and set REGISTER_PREFIX to %.
6230 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

6248 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6249 sections starting from zero, rather than making them consecutive.
6250 This makes subsequent reloc calculations easier, esp if the object
6251 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6252 allocate lcomm in .data rather than in .bss. It seems that some
6253 tools can't cope with a non-zero sized bss before linkage.
6255 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6257 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

6276 * Makefile.in (install): if $(tooldir) exists, install as in
6279 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6281 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6282 .word is < -32768 or > 32767. The -J flag causes the error to be
6283 ignored. This is to catch over-sized switches generated by gcc on
6284 systems which don't support the broken .word hack.
6285 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6286 write.c (fixup_segment): check for signed .word overflow if
6287 WARN_SIGNED_OVERFLOW_WORD.

6306 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6308 * input-scrub.c (input_scrub_push): call input_file_begin, not
6310 messages.c (as_perror): print ": " between the passed in error and
6311 the strerror, like perror does.

6316 From Steve Chamberlain:
6317 Makefile.in: Handle m68*-*-coff*.
6318 read.c, read.h: add mult argument to s_space
6320 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6321 Motorola and MIT syntax; gas can now assemble either type of
6323 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6330 (fixup_segment) set fx_subsy to 0.
6331 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6333 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6336 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6338 * Makefile.in (LIBS): Include opcode library.

6363 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6365 * config/tc-m68k.c (init_table): Now const. Always include 68851
6366 data, so that "bc" is available to 68040 cache instructions.
6367 Added "tt0", "tt1", and 68ec030 variants.
6368 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6369 (enum _register): Added TT0, TT1.
6370 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6371 line number correctly in "internal error" messages. Don't print
6372 architecture-mismatch message for operand errors.
6374 From Colin Smith (colin@wrs.com):
6375 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

6397 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6398 has already been formatted (but may still contain %-characters).
6401 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6403 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6404 written with indirection on the last two operands, which can be
6405 either data or address registers. Added a new operand type 'r'
6406 which accepts either register type. Added '(' to notend stuff in
6407 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6426 their not having symbols associated.
6428 * tc-i960.c (norelax, instrument_branches): Default initializer is

6454 being used with args swapped, causing occasional lossage when
6455 refilling buffers after an include file.
6457 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
6459 * messages.c (as_tsktsk): Use correct ANSI form for stdarg

6465 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6466 selected architecture, print a message saying so and listing what

6513 * expr.c (floating_constant): Separate "=-" to avoid confusing
6514 ancient or broken compilers.
6516 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
6517 processor/opcode mismatch, so reword the error message.
6518 (md_assemble): If no CPU has been set (even if FPU/PMMU
6519 characteristics have been), default to 68020. Don't need extra
6520 quotes around error string.

6582 pcrel data stuff. (md_estimate_size_before_relax): when relaxing a
6583 68010 bxx into a bra+6 jmpxx, put the bytes of the jmp opcode into
6584 the right place. (s_bss): Don't put .bss stuff into SEG_DATA, put

6589 * expr.c(expr): allow SEG_REGISTER in expressions.
6590 * read.c(pseudo_set): register expressions can be the source of a
6592 * subsegs.c (subseg_new): Now -R forces all changes to SEG_DATA to
6593 goto SEG_TEXT (if a.out)
6594 * write.c (write_object_file): If a.out don't use the old way for
6596 * config/obj-a.out (s_sect): complain if the user tries to use a
6597 subsegment with a value which might interfere with out -R hackery.
6598 * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
6599 rather than use ugly if tree. (init_regtable): insert register
6600 names into symbol table.
6602 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6604 * write.c (write_object_file): keep the fix_tail clean, which
6605 fixes a bug in -R where relocations were being lost.
6607 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6609 * configure.in: recognize m680x0 as having sun3 emulation mode for
6610 vxworks environment.
6612 Sun May 31 05:33:00 1992 david d `zoo' zuhn (zoo@cygnus.com)

6632 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6634 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
6635 calc the base of relocs correctly.
6636 * tc-a29k.c (parse_operand): allow expressions to be in any section.
6638 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
6640 * as.c, write.c: use -K rather than -k for the broken word warning
6643 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)

6651 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6653 * write.c (write_object_file): For b.out format, round up section
6654 start addresses to match required alignment.
6656 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6658 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6659 where gcc looks for it.
6661 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6663 * Makefile.in: Changed some lines to be less confusing for some
6666 * input-file.c: Conditionalize on _IOFBF, not VMS.
6668 * read.c, write.c: Change a series of ifdef/elif to
6669 ifdef/else/ifdef etc.

6688 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
6690 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
6691 tc-m68k.h to te-sun3.h.
6693 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
6695 * configure.in: vxworks68 gets te-sun3.h.
6697 * expr.c: remove limitation that local_labels_dollar or
6698 local_labels_fb must be < 10.
6700 * symbols.c: remove local_labels_dollar, replace with a function
6701 interface for a sparse array. All users adjusted.
6703 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
6705 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6707 * doc/Makefile.in: commented out line for building as-all.texinfo.
6710 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
6712 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
6714 * Makefile.in: added check target.
6716 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)

6726 * Makefile.in (strerror.o): Add rule so that broken Sun make can
6729 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6731 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6733 * expr.c (operand): if can't work out what sort of operand it is,
6734 then look through FLT_CHARS for a hint.
6736 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6738 * Makefile.in, configure.in: removed traces of namesubdir,
6739 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6740 copyrights to '92, changed some from Cygnus to FSF.
6742 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6743 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6744 copyrights to '92, changed some from Cygnus to FSF.
6746 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6748 * expr.c: If an expression is single comma, then return with
6749 SEG_ABSENT rather than an error - since the sparc front end does
6750 really strange things with things like fbge,a
6752 * as.h: include bfd.h if using many sections
6753 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6754 local labels didn't work.
6755 * listing.c (list_symbol_table): don't core dump when there's no
6757 * write.c, write.h: call fix_new with the right number of args on
6759 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6762 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6764 * app.c: MRI compatibility - allow single quote to start a string.
6765 * as.c: fix typo recently introduced.
6766 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6767 * expr.c: Much rewriting, to accomodate MRI syntax for
6768 expressions. Also easier to read now.
6769 * listing.c: Put back defuns
6770 * read.c: modified to accept MRI syntax, put back listing pseudo
6771 ops so that an assembler built with NO_LISTING ignores list ops
6773 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6774 machine is a SPARC or a 29K.
6775 * config/obj-aout.c: added s_sect pseudo op
6776 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6777 fill in the timestamp.
6778 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6779 anymore, define all the relocs which the tc-<x> bit will use so we
6780 can translate from them to the coff types.
6781 * config/tc-a29k.c: reloc_type isn't ane enum any more
6782 * config/tc-m68k.c: Added NO_RELOC definition.
6784 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6786 * Makefile.in: put header files before C source for TAGS; remove
6787 references to non-existent syscalls.h.
6789 * read.c, write.c subsegs.c: back out the .bss changes.
6791 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6793 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6797 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6799 * symbols.c (local_label_name): symbols now start with ^A.
6801 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6802 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6803 generate these sections. .align: will use NOP_OPCODE or 0
6804 for padding. This is just for being nice to the
6807 * expr.c (operand): changed to generate local label "\001L0"
6808 starting with a ^A so that it is recognized as a local label.
6810 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6812 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6813 i/o opcodes - inb, inw, outb and outw. string manipulation with
6814 att syntax - scmp, slod, smov, ssca, ssto.
6816 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6817 to just after .file .
6819 In obj_crawl_symbol_chain() where it tries to put the external
6820 symbols apart, with the condition:
6821 (!S_IS_DEFINED(symbolP) &&
6822 !S_IS_DEBUG(symbolP) &&
6823 !SF_GET_STATICS(symbolP))
6824 it was moving too many symbols out. So I switch it back to the
6826 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6828 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6829 so that we don't use the F_RELFLG which make the linker complain
6830 that somebody has stripped the relocation info.
6832 Also, the AIX ld program require that the relocation table
6833 is sorted by r_vaddr like the standard ATT assembler does.
6835 [he also changed the sizeof(struct ...)'s into the coff
6836 style FOOSZ macros. I'm not sure this is right, but I can't
6837 remember why. xoxorich.]
6839 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6841 * Makefile.in, configure.in, doc: use the doc. Build it, install
6844 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6846 * read.c: white space and comments only.
6848 * configure.in: use the new atof-ns32.c for ns32k.
6850 * write.c: comment change only.
6852 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6853 aren't yet integrated.
6855 * tc-i860.[hc]: blew off the dust. Something must still be done
6856 about conflicting relocation types.
6858 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6861 * tc-i960.c, tc-sparc.c: white space and comments only.
6863 * tc-a29k.h: delete duplicate macro definition.
6865 * new file atof-ns32k.c copied from hack's last unreleased gas.
6867 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6869 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6872 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6873 ChangeLog's prior to this are sketchy at best. I have logs.
6874 They just aren't ChangeLogs.
6878 version-control: never
