125 * config/obj-coff.c (coff_frob_symbol): Use C_STAT for the .text
126 section symbol, not C_LABEL.
128 * config/tc-mips.c (mips_ip): Permit a modifier in 'o' case, and
129 permit non constant expressions in 'u' case. Lets ``lui

180 * read.c (emit_expr): Use memset to zero out memory, rather than
181 going through md_number_to_chars. This permits handling symbolic
182 arguments when the size is larger than sizeof (valueT), if

235 (control_regs): New pointer.
236 (m68k_ip): Use control_regs instead of testing CPU every time.

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

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

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

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

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

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

788 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
789 flag rather than signedp field. Only permit extended range if
790 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
791 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
793 * config/tc-ppc.c (ppc_size): New static variable.
794 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.

831 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
832 branch with an instruction that uses $at, in case the branch is
834 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.

836 to make it pcrel_offset.
837 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
838 reloc->address; another gruesome hack to get gas reloc handling to

851 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
852 tested by code that might want to emit a LITUSE reloc.
853 (emit_unaligned_io): New function. Currently calls md_assemble,
854 but it should eventually be converted to generate the insn itself
855 and call emit_insn directly.

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

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

907 * Makefile.in (config-stamp): If `defs' is defined, emit a
908 preprocessor directive to create a macro named by this value into
909 config.new; don't explicitly go for BFD_ASSEMBLER.

911 MANY_SEGMENTS for any obj-coffbfd target.
912 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.

944 (dump_section_relocs): Note whether a symbol is a section symbol
946 (adjust_reloc_syms): For now, always supply an absolute symbol for
947 fixups without symbols but not yet `done'. Use section_symbol to
948 get the symbol, instead of going directly for abs_symbol.
949 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
950 reloc is not a section symbol and is not in the symbol table.
951 (set_symtab): New function, broken out from write_object_file.

953 (write_object_file): Call set_symtab, but do it after potentially
954 invoking the *_frob_file macros. Don't bother counting symbols.
955 Call symbol_remove, instead of expanding it in place. Moved the

3124 * write.c (write_relocs): For relocs that are pc_relative and
3125 pcrel_offset and not partial_inplace, adjust reloc->addend to

3181 for keeping or rejecting configurations still under development;
3182 default is to assume production environment, and reject configs
3183 still being worked on. Mark Elf configurations (except sparc and
3184 i386) as developmental. Deleted cases matching some generic names
3185 in favor of more specific names. (E.g., when we get Alpha

3211 into a few places. Make all functions and variables which
3212 are only used within tc-hppa.c static. PARAMize all functions.
3213 Add comments to functions. Delete unused functions, variables,
3214 #defines, etc. Delete unused members within structures. Delete
3215 ldil;ble hacks -- it is believed they were installed to work
3216 around old gas bugs. Avoid using mixed case for local
3217 functions, variables, and structures. Fix formatting problems
3218 not found by GNU-indent. Add FIXME notices for things which
3219 should be worked on the near future. Delete lots of old
3220 useless (1.36 PA-SOM) code.

3295 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
3296 call strchr for each character to see if it is a special char,

3298 of text, data and bss sections to 4.
3299 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be

4382 * Extensive changes to permit symbols to contain any expression
4383 type and to delay the computation of the expression until the
4384 value is actually needed. This permits setting symbols to values
4385 calculated based on object code size. Expressions were changed to
4386 no longer be in a section, to stop the overloading of segment and
4387 expression type that previously occurred.
4389 * as.c (big_section, pass1_section, diff_section, absent_section):
4391 (expr_section): Added (used for dummy symbols which hold

4475 (previous_section, previous_subsection): New vars.
4476 (obj_elf_section): Save current place in case DWARF code wants us
4477 to pop back to it. Handle unquoted section name as well as quoted
4478 section name. Don't crash on invalid strings.
4479 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

4591 sy_resolved and sy_resolving single bit fields.
4592 * symbols.c (symbol_new): Don't initialize sy_forward field.

5626 than ECOFF line number information.
5627 (obj_ecoff_stab): Accept non-zero values for stabs line number.

5654 references don't appear to work right.
5656 * as.h (const, volatile): Put these definitions back, and use
5659 * doc/as.texinfo: First pass at using new texinfo features --
5660 variables, conditional tests. Far from complete.

5686 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
5687 the bottom (make expands variables in dependencies when the
5688 dependencies are read, not when they are used).
5690 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
5691 a29k .bss section; the mondfe program doesn't like it.

5712 source directory, if that's not the current directory.
5714 * configure.in (per-host): Accept MIPS host with BSD version

5735 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
5736 process relocs if there aren't any relocs to process. Avoids
5737 malloc/free bug on SCO too.
5739 * as.h: Move local include files below system include files, to
5740 avoid some redefinition complaints on some systems.
5741 (const, volatile): Don't need these conditionally defined if we
5742 use CONST and VOLATILE from ansidecl.h.
5743 (seg_name): Use CONST, not const.
5745 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5747 * config/tc-mips.c: Reindented to GNU standards.
5749 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
5751 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5752 (fixup_segment): Add a29k special case; the linker is not prepared
5753 to see a segment offset here.
5755 * app.c (do_scrub_next_char): Added new state, 10, modifying state
5756 9 to only keep a space in between identifier characters.
5758 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5760 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5761 srcdir, might be in objdir.
5763 * doc/Makefile.in: dvi depends on as.dvi

5781 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
5782 bignums, but don't emit error message.
5784 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
5786 * Makefile.in (targ-cpu.o): Depend on config.h.
5788 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5790 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5791 dropping a space immediately following an identifier.
5792 * expr.c, write.c: Rewrote assert expressions to not use multiple
5793 lines; I don't think that can be done portably.
5794 * config/tc-mips.c (macro): Use $AT if target register is zero in
5795 load instruction, which it can be for a floating point load.
5797 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5808 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
5809 z8k-opc.h, not z8k.h.
5811 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
5814 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5816 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
5818 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5820 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5821 to be on a single line.

5865 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
5866 (struct loc, struct proc, struct file): Moved to tc-mips.c within
5867 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.

5869 prototypes for all static functions. Moved existing minimal
5870 debugging format support info #ifndef OBJ_ECOFF blocks.
5871 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
5872 does not support a non sign extended high 16 bits reloc. Adjusted
5873 all callers accordingly.
5874 (tc_get_register): Renamed from get_register, and made non-static.
5876 * config/mips-big.mt, config/mips-lit.mt: New files. Define

5919 * make-gas.com: Find obstack.obj if it's not in the current
5921 * read.c (s_ignore): Don't declare is_end_of_line. It's
5922 redundant, and triggers a VMS gcc compiler bug.
5924 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5925 current segment as an argument. (Ignored in all cases but VMS.)
5926 All callers and definitions changed.

5942 (obj_elf_xstab): New routine.
5943 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
5944 argument to s_ignore. Put "#if 0" around unused code.
5945 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
5946 Call elf_xstabs for .stabs and .xstabs operators.
5948 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
5950 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
5953 * configure.in: mips-bsd configuration was missing format spec.
5956 * Makefile.in (Makefile): Depends on configure.in.
5958 * config/tc-mips.c (append_insn): Don't check for alignment of
5959 frag in memory; alignment of instructions in section is a separate
5962 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI

5979 * config/tc-sparc.c (s_xword): Now call big_cons, so large
5980 constants are accepted, but symbolic values are not. GCC will not
5981 generate the latter currently.
5983 * frags.c (frag_init): New function.
5984 (zero_address_frag, bss_address_frag): Now initialized at run
5986 * as.c (main): Call frag_init.

6030 (fixup_segment): Make sure common-section symbols get treated the
6031 same as undefined symbols.
6032 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type
6033 bfd_reloc_code_real_type. Use seg_fix_{root,tail}P derived from

6040 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and
6043 * symbols.c (symbol_new): Argument NAME is now pointer to const.
6044 Simplified STRIP_UNDERSCORE code. Remove assumptions about null
6045 pointers in freshly allocated storage. [BFD_ASSEMBLER]: Get new

6062 new section/subsection.
6064 * read.c: Don't include ctype.h.
6065 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
6066 for now; should be machine-dependent.
6068 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
6069 targets, forcing BFD use.

6073 * config/tc-sparc.c: Use PARAMS macro for static function
6074 declarations. Use BFD_RELOC_ macros everywhere, with
6075 compatibility macros declared for non-BFD mode.
6076 (struct sparc_it) [BFD_ASSEMBLER]: Use bfd_reloc_code_real_type
6077 instead of enum reloc_type.

6087 of referencing fields directly.
6089 * write.c (cvt_frag_to_fill): New function; extracted from
6091 (write_object_file) [! BFD_ASSEMBLER]: Call it.
6092 (relax_and_size_seg) [BFD_ASSEMBLER]: New function; relax section
6093 and set its size and flags.
6095 * struc-symbol.h (struct symbol) [BFD_ASSEMBLER]: Replace some
6096 fields with BFD equivalents. Turn on back-pointers, and add

6253 * expr.c (operand): If character other than comma or newline is a
6254 logical end-of-line character, use the newline case.
6255 From Eric Youngdale:
6256 (operand): Set X_add_number field for floating-point numbers.
6257 (operand): Treat zero byte as end-of-operand.
6259 * configure.in (per-target): Look for with_bfd_assembler option.
6260 For now, only accept "no", until the merge is done.
6262 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):

6269 * expr.c: Add "const" modifier to hex_value.
6270 * symbols.c: Finish conversion to S_* macros in the VMS only
6271 parts of the program. Add "const" modifier to
6272 md_[long,short]_jump_size. Remove declaration of const_flag
6273 (which will be declared in obj-vms.h).
6274 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6275 Fix arguments to VMS_write_object_file.
6276 * config-gas.com: New file. Script for VMS systems to set up the
6277 configuration to build gas for VMS, and create config.status.
6278 * make-gas.com: Redone to work with new scheme.
6279 * obj-vms.c: Patch to fix bug where we were not correctly parsing the

6284 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
6285 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6286 types of malformed stabs. Change parsing algorithm so that we are
6287 more certain of having all of the information that we need on hand.
6288 * obj-vms.c (final_forward_reference): New function, used to help
6289 resolve the data types of as many struct elements as possible

6293 * obj-vms.c (VMS_write_object_file): Define all vtable psects
6294 as symbols as well in the object file. Look for external functions

6296 g++ compiler is incapable of doing this.
6297 * tc-vax.c: Add '1' option for backward compatibility with older GCC
6299 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
6300 * input-scrub.c (as_where): Fix bug where as would crash if we did not
6301 have the name of the source file yet.
6302 * config/ho-vms.h: define HO_VMS, not HO_VAX.
6304 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
6306 * read.c (s_data): Always use "data_section", since it'll map to
6307 SEG_DATA or SEG_E1 if needed.
6308 (s_lcomm): Likewise with bss_section.
6309 (s_fill): Use memset, not bzero.
6311 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

6333 (big_section, reg_section, pass1_section, diff_section,
6334 absent_section, text_section, data_section, bss_section): If
6335 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
6336 mapping to segT enum values.
6337 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
6338 if these are used or defined, if BFD_ASSEMBLER.
6339 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6340 subseg_new split into two functions.
6341 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6343 * as.h (volatile): Don't define if already defined.
6344 (had_errors, had_warnings): Provide prototypes for ANSI C even if
6346 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
6347 declare with format attribute for -Wformat checking.
6349 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
6351 * app.c, config/tc-*.c: Don't include read.h, since it is already
6354 * These are based on patches from Minh Tran-le
6355 <mtranle@paris.intellicorp.com>.
6356 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
6357 obj_format coffbfd and gas_target i386coff for target.
6358 (i[34]86-*-isc*): New host (uses sysv).
6359 * config/i386aix.mt: Removed (no longer used).
6360 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
6362 (LDFLAGS): Added, defined as -shlib.
6363 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
6364 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6365 (DOT_LABEL_PREFIX): Define.

6379 (size_section): Restored sanity check.
6380 (do_relocs_for): Base section address on s_paddr rather than
6381 computing it. Adjust a29k R_IHIHALF special case to account for
6382 section paddr (used to require paddr to be zero). If there are no
6383 reclos, set s_relptr to 0. Set relocation size in object_headers.
6384 (fill_section): Always set s_vaddr here, removing
6385 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6386 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6387 Set STYP_INFO for .comment.
6388 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
6389 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

6391 H_{SET,GET}_* macros.
6392 (do_linenos_for): Set lineno size in object_headers.
6393 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6394 set s_vaddr here. If string_byte_count remains 4, set it back to
6395 0, and only write strings out if there are some. Call
6396 fill_section before do_relocs_for and do_linenos_for.
6397 (obj_coff_section): Handle optional quoted second argument giving
6398 section characteristics.
6399 (obj_coff_bss): Added to handle .bss.
6400 (obj_coff_ident): Added to handle .ident (puts string in .comment

6420 (do_scrub_next_char): For \", return " not '.
6421 (symbol_chars): Now const.
6423 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6424 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6426 * config/obj-coff.h: Don't use #elif.
6428 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6429 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
6431 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
6433 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

6455 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6456 using ZERO_BASED_SEGMENTS.
6457 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6458 never set segment address for SEG_E2 (.bss) and don't write out
6459 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6460 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6461 definitions, and don't merge tags with non-tags. Check for .bf
6462 rather than just checking whether the second character is b and
6463 the third character is f.
6464 (obj_coff_val): gcc can generate values which we don't handle
6465 correctly; discard information for now, since it only affects the
6466 debugging information.

6468 (yank_symbols): Don't merge labels.
6469 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6524 options. Updated options documentation for m68k. Some minor
6525 wording/punctuation changes.

6579 xrealloc from xrealloc.c.
6580 * xrealloc.c: Deleted.
6581 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
6583 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
6586 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
6588 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;

6607 * all files: Whitespace changes for GNU indentation style, done by
6608 GNU `indent'. Some cleanup still needed, especially of comments.
6610 * configure.in: No te-386bsd.h file exists; don't try to use it.
6612 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
6614 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
6615 could be doing emulation.
6617 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6620 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6647 consistently const, and always initialized them. Included read.h.
6649 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6651 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6652 constant will not fit in an immediate field.
6653 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
6655 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
6657 * obj-coff.c (callj_table): Delete global variable.

6675 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
6677 * version.c: Put conditional "const" before version_string, not
6678 before dummy function for VMS. Now version 1.91.03.
6680 * app.c (do_scrub_next_char): Need double-\ before `000' to show
6681 printed rep of null character.
6683 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
6685 * obj-coffbfd.c (write_object_file): check return value of
6688 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6690 * Support for i386-sysv.
6691 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
6692 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
6693 be used to set them all to zero as was done before.
6694 (fill_section): segment addresses now set in write_object_file.
6695 (fill_section): Don't set STYP_NOLOAD for .bss section.
6696 (fixup_segment): 386 uses strange common symbol format.
6697 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
6698 compatibility with SVR3.2 linker.
6699 * configure.in: i386-sysv and i386-sco use coffbfd.
6701 * app.c (do_scrub_next_char): discard whitespace after a label.

6715 * tc-m68k.c (get_num): make it work for all segments, not just the
6718 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
6720 * configure.in: recognize i386-*-bsd emulation.

6729 * tc-z8k.c: lots of bug fixes
6731 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6733 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6734 #elif, since it is not supported by old compilers.
6735 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6736 couple of expressions in tc-m68k.c.
6738 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6740 * read.c (cons): If NO_RELOC is defined, use it.
6742 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6744 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6746 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6747 local labels to start with a .) and set REGISTER_PREFIX to %.
6748 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6750 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

6764 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6766 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6767 sections starting from zero, rather than making them consecutive.
6768 This makes subsequent reloc calculations easier, esp if the object
6769 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6770 allocate lcomm in .data rather than in .bss. It seems that some
6771 tools can't cope with a non-zero sized bss before linkage.
6773 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6775 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6776 throughout. That enum no longer means what we thought it meant.

6779 "-mno-688[58]1" options.
6781 * tc-m68k.c: Added CPU32 support.

6790 Change LIBDEPS dependence to LIBS.
6792 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6794 * Makefile.in (install): if $(tooldir) exists, install as in
6797 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6799 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6800 .word is < -32768 or > 32767. The -J flag causes the error to be
6801 ignored. This is to catch over-sized switches generated by gcc on
6802 systems which don't support the broken .word hack.
6803 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6804 write.c (fixup_segment): check for signed .word overflow if
6805 WARN_SIGNED_OVERFLOW_WORD.
6807 * write.c (fixup_segment): fixed missing parens in expression
6808 checking for byte or word overflow.
6810 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

6820 * obj-coffbfd.h : added stuff
6821 * tc-i386.c (tc_coff_fix2rtype): new function
6822 * tc-i386.h : new coff defines
6824 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6826 * input-scrub.c (input_scrub_push): call input_file_begin, not
6828 messages.c (as_perror): print ": " between the passed in error and
6829 the strerror, like perror does.
6831 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6833 * Makefile.in: use gas_target instead of modifying target_cpu.
6834 From Steve Chamberlain:
6835 Makefile.in: Handle m68*-*-coff*.
6836 read.c, read.h: add mult argument to s_space
6838 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6839 Motorola and MIT syntax; gas can now assemble either type of
6841 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
6842 From Steve Chamberlain:
6843 m68kcoff.mt: for m68k COFF.
6844 obj-coffbfd.c: (fixup_mdeps) added

6847 (write_object_file) call fixup_mdeps
6848 (fixup_segment) set fx_subsy to 0.
6849 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6851 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6854 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6856 * Makefile.in (LIBS): Include opcode library.
6858 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
6860 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
6861 including zero are accepted, pass +0.0.

6878 tc-i960.c (md_ri_to_chars): Always output bout object file in
6879 little endian byte order (used to use endianness of host).
6881 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6883 * config/tc-m68k.c (init_table): Now const. Always include 68851
6884 data, so that "bc" is available to 68040 cache instructions.
6885 Added "tt0", "tt1", and 68ec030 variants.
6886 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6887 (enum _register): Added TT0, TT1.
6888 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6889 line number correctly in "internal error" messages. Don't print
6890 architecture-mismatch message for operand errors.
6892 From Colin Smith (colin@wrs.com):
6893 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6894 than install_operand.

6898 * listing.c (buffer_line): rewind to the start of include
6899 files, they might be included twice.

6906 one element of a family.
6908 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
6910 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6911 so that we can assemble hand-written libgcc code.
6913 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6915 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6916 has already been formatted (but may still contain %-characters).
6919 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6921 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6922 written with indirection on the last two operands, which can be
6923 either data or address registers. Added a new operand type 'r'
6924 which accepts either register type. Added '(' to notend stuff in
6925 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6927 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
6929 * as.h (enum _relax_state): Start off at one, not zero, to better

6939 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
6940 defined, call it. Change segments before calling fixup_segment.
6941 (relax_align): If linkrelax, provide extra padding.
6943 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6944 their not having symbols associated.
6946 * tc-i960.c (norelax, instrument_branches): Default initializer is
6948 (linkrelax): Delete variable definition.

6969 Mon Aug 17 15:09:56 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6971 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
6972 being used with args swapped, causing occasional lossage when
6973 refilling buffers after an include file.
6975 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
6977 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6978 version. Discard bogus DONTDEF version.
6979 (as_warn, as_bad, as_fatal): Likewise.
6981 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
6983 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6984 selected architecture, print a message saying so and listing what
6985 processors support it, rather than saying "operands mismatch".

7002 if TN_SUN3; otherwise align to 2**N-byte bounary.
7004 Thu Aug 6 12:10:39 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7006 * read.c (s_fill): make the .fill size clamped error a warn and
7007 fix bug where 0's were always placed.
7009 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
7010 two bytes of any constant with 0xff:
7012 Wed Aug 5 12:02:40 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7014 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
7015 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.

7025 fx_offset into account.
7027 Fri Jul 31 21:53:28 1992 Ken Raeburn (raeburn@cygnus.com)
7029 * configure.in (mips host): Accept "ultrix" with version number.
7031 * expr.c (floating_constant): Separate "=-" to avoid confusing
7032 ancient or broken compilers.
7034 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
7035 processor/opcode mismatch, so reword the error message.
7036 (md_assemble): If no CPU has been set (even if FPU/PMMU
7037 characteristics have been), default to 68020. Don't need extra
7038 quotes around error string.
7040 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
7042 * read.c (potable): Revert sac's incorrect change made Jul 13.
7043 Align really is supposed to be ptwo not nbytes.

7122 * write.c (write_object_file): keep the fix_tail clean, which
7123 fixes a bug in -R where relocations were being lost.
7125 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
7127 * configure.in: recognize m680x0 as having sun3 emulation mode for

7172 start addresses to match required alignment.
7174 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
7176 * Makefile.in (install): Install into $(tooldir)/bin, since that's
7177 where gcc looks for it.
7179 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
7181 * Makefile.in: Changed some lines to be less confusing for some

7247 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
7249 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
7251 * expr.c (operand): if can't work out what sort of operand it is,
7252 then look through FLT_CHARS for a hint.
7254 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
7256 * Makefile.in, configure.in: removed traces of namesubdir,
7257 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
7258 copyrights to '92, changed some from Cygnus to FSF.
7260 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
7261 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
7262 copyrights to '92, changed some from Cygnus to FSF.
7264 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7266 * expr.c: If an expression is single comma, then return with
7267 SEG_ABSENT rather than an error - since the sparc front end does
7268 really strange things with things like fbge,a
7270 * as.h: include bfd.h if using many sections
7271 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
7272 local labels didn't work.
7273 * listing.c (list_symbol_table): don't core dump when there's no
7275 * write.c, write.h: call fix_new with the right number of args on
7277 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
7280 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7282 * app.c: MRI compatibility - allow single quote to start a string.
7283 * as.c: fix typo recently introduced.
7284 * as.h : Don't include aout/reloc.h - it's not right for COFF!
7285 * expr.c: Much rewriting, to accomodate MRI syntax for
7286 expressions. Also easier to read now.
7287 * listing.c: Put back defuns
7288 * read.c: modified to accept MRI syntax, put back listing pseudo
7289 ops so that an assembler built with NO_LISTING ignores list ops
7291 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7292 machine is a SPARC or a 29K.
7293 * config/obj-aout.c: added s_sect pseudo op
7294 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7295 fill in the timestamp.
7296 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7297 anymore, define all the relocs which the tc-<x> bit will use so we
7298 can translate from them to the coff types.
7299 * config/tc-a29k.c: reloc_type isn't ane enum any more
7300 * config/tc-m68k.c: Added NO_RELOC definition.
7302 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
7304 * Makefile.in: put header files before C source for TAGS; remove
7305 references to non-existent syscalls.h.
7307 * read.c, write.c subsegs.c: back out the .bss changes.
7309 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7311 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
7315 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7317 * symbols.c (local_label_name): symbols now start with ^A.
7319 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7320 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7321 generate these sections. .align: will use NOP_OPCODE or 0
7322 for padding. This is just for being nice to the
7325 * expr.c (operand): changed to generate local label "\001L0"
7326 starting with a ^A so that it is recognized as a local label.
7328 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7330 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7331 i/o opcodes - inb, inw, outb and outw. string manipulation with
7332 att syntax - scmp, slod, smov, ssca, ssto.
7334 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7335 to just after .file .
7337 In obj_crawl_symbol_chain() where it tries to put the external
7338 symbols apart, with the condition:
7339 (!S_IS_DEFINED(symbolP) &&
7340 !S_IS_DEBUG(symbolP) &&
7341 !SF_GET_STATICS(symbolP))
7342 it was moving too many symbols out. So I switch it back to the
7344 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7346 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7347 so that we don't use the F_RELFLG which make the linker complain
7348 that somebody has stripped the relocation info.
7350 Also, the AIX ld program require that the relocation table
7351 is sorted by r_vaddr like the standard ATT assembler does.
7353 [he also changed the sizeof(struct ...)'s into the coff
7354 style FOOSZ macros. I'm not sure this is right, but I can't
7355 remember why. xoxorich.]
7357 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
7359 * Makefile.in, configure.in, doc: use the doc. Build it, install
7362 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
7364 * read.c: white space and comments only.
7366 * configure.in: use the new atof-ns32.c for ns32k.
7368 * write.c: comment change only.
7370 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7371 aren't yet integrated.
7373 * tc-i860.[hc]: blew off the dust. Something must still be done
7374 about conflicting relocation types.
7376 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7379 * tc-i960.c, tc-sparc.c: white space and comments only.
7381 * tc-a29k.h: delete duplicate macro definition.
7383 * new file atof-ns32k.c copied from hack's last unreleased gas.
7385 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7387 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7390 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7391 ChangeLog's prior to this are sketchy at best. I have logs.
7392 They just aren't ChangeLogs.
7399 version-control: never
