1042 pass new argument for i, j and o cases.
1043 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

1264 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
1265 the table, require that the one without bit 0x1000000 set come

1377 for keeping or rejecting configurations still under development;
1378 default is to assume production environment, and reject configs
1379 still being worked on. Mark Elf configurations (except sparc and
1380 i386) as developmental. Deleted cases matching some generic names
1381 in favor of more specific names. (E.g., when we get Alpha

1396 against placing additional object-file dependent code here. Warn
1397 against contaminating all of GAS with the internals of tc-hppa.c
1398 through inclusion of tc-hppa.h. Delete all forward declarations
1399 for functions only used within tc-hppa.c, likewise for structures,
1400 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1401 conditional code in a few small places.
1403 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1404 structures, global variables, forward declarations together.

1407 into a few places. Make all functions and variables which
1408 are only used within tc-hppa.c static. PARAMize all functions.
1409 Add comments to functions. Delete unused functions, variables,
1410 #defines, etc. Delete unused members within structures. Delete
1411 ldil;ble hacks -- it is believed they were installed to work
1412 around old gas bugs. Avoid using mixed case for local
1413 functions, variables, and structures. Fix formatting problems
1414 not found by GNU-indent. Add FIXME notices for things which
1415 should be worked on the near future. Delete lots of old
1416 useless (1.36 PA-SOM) code.
1418 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
1419 field of the fixS structure. Needed to build unwind

2559 * Extensive changes to permit symbols to contain any expression
2560 type and to delay the computation of the expression until the
2561 value is actually needed. This permits setting symbols to values
2562 calculated based on object code size. Expressions were changed to
2563 no longer be in a section, to stop the overloading of segment and
2564 expression type that previously occurred.
2566 * as.c (big_section, pass1_section, diff_section, absent_section):
2568 (expr_section): Added (used for dummy symbols which hold

2652 (previous_section, previous_subsection): New vars.
2653 (obj_elf_section): Save current place in case DWARF code wants us
2654 to pop back to it. Handle unquoted section name as well as quoted
2655 section name. Don't crash on invalid strings.
2656 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

2678 calculating opP->isiz; this permits the expression size to be
2679 determined as well, later on.

2765 * Removed sy_forward and replaced it with an undefined expression
2766 as the value of a symbol.
2767 * struc-symbol.h (struct symbol): Removed sy_forward field. Added
2768 sy_resolved and sy_resolving single bit fields.
2769 * symbols.c (symbol_new): Don't initialize sy_forward field.
2770 (resolve_symbol_value): New function to adjust symbol value by
2771 fragment address, using recursion to resolve forward symbols.

2773 * read.c (pseudo_set): Set symbolP->sy_value to an undefined
2774 expression rather than setting symbolP->sy_forward.
2775 * write.c (write_object_file): Use resolve_symbol_value on
2776 symbols, keeping the common case (the old behaviour) inline.
2777 * config/obj-aout.c (obj_aout_frob_symbol): Removed sy_forward
2778 handling (subsumed by write.c change).

3772 than ECOFF line number information.
3773 (obj_ecoff_stab): Accept non-zero values for stabs line number.

3805 * doc/as.texinfo: First pass at using new texinfo features --
3806 variables, conditional tests. Far from complete.

3834 dependencies are read, not when they are used).
3836 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
3837 a29k .bss section; the mondfe program doesn't like it.

3858 source directory, if that's not the current directory.
3860 * configure.in (per-host): Accept MIPS host with BSD version

3882 process relocs if there aren't any relocs to process. Avoids
3883 malloc/free bug on SCO too.
3885 * as.h: Move local include files below system include files, to
3886 avoid some redefinition complaints on some systems.
3887 (const, volatile): Don't need these conditionally defined if we
3888 use CONST and VOLATILE from ansidecl.h.
3889 (seg_name): Use CONST, not const.
3891 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3893 * config/tc-mips.c: Reindented to GNU standards.
3895 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
3897 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3898 (fixup_segment): Add a29k special case; the linker is not prepared
3899 to see a segment offset here.
3901 * app.c (do_scrub_next_char): Added new state, 10, modifying state

3904 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3906 * Makefile.in: add dvi target; as-$(config).texinfo might live in
3907 srcdir, might be in objdir.

3922 bignums, but don't emit error message.
3924 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
3926 * Makefile.in (targ-cpu.o): Depend on config.h.
3928 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3930 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3931 dropping a space immediately following an identifier.
3932 * expr.c, write.c: Rewrote assert expressions to not use multiple
3933 lines; I don't think that can be done portably.
3934 * config/tc-mips.c (macro): Use $AT if target register is zero in
3935 load instruction, which it can be for a floating point load.
3937 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3958 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3960 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3961 to be on a single line.
3963 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3965 * Makefile.in (config.h): Create file, writing out definitions of

4009 prototypes for all static functions. Moved existing minimal
4010 debugging format support info #ifndef OBJ_ECOFF blocks.
4011 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
4012 does not support a non sign extended high 16 bits reloc. Adjusted
4013 all callers accordingly.
4014 (tc_get_register): Renamed from get_register, and made non-static.
4016 * config/mips-big.mt, config/mips-lit.mt: New files. Define

4059 * make-gas.com: Find obstack.obj if it's not in the current
4061 * read.c (s_ignore): Don't declare is_end_of_line. It's
4062 redundant, and triggers a VMS gcc compiler bug.
4064 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4065 current segment as an argument. (Ignored in all cases but VMS.)
4066 All callers and definitions changed.

4085 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
4086 Call elf_xstabs for .stabs and .xstabs operators.

4096 * Makefile.in (Makefile): Depends on configure.in.
4098 * config/tc-mips.c (append_insn): Don't check for alignment of
4099 frag in memory; alignment of instructions in section is a separate

4363 md_relax_table): Use default zero initialization.
4364 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4365 latter, instead of selecting with preprocessor conditionals.
4367 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4369 * configure.in: recognise all sparclite variants

4377 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4379 * expr.c (operand): If character other than comma or newline is a
4380 logical end-of-line character, use the newline case.
4381 From Eric Youngdale:
4382 (operand): Set X_add_number field for floating-point numbers.
4383 (operand): Treat zero byte as end-of-operand.
4385 * configure.in (per-target): Look for with_bfd_assembler option.
4386 For now, only accept "no", until the merge is done.
4388 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4389 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4395 * expr.c: Add "const" modifier to hex_value.
4396 * symbols.c: Finish conversion to S_* macros in the VMS only
4397 parts of the program. Add "const" modifier to
4398 md_[long,short]_jump_size. Remove declaration of const_flag
4399 (which will be declared in obj-vms.h).
4400 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4401 Fix arguments to VMS_write_object_file.
4402 * config-gas.com: New file. Script for VMS systems to set up the
4403 configuration to build gas for VMS, and create config.status.
4404 * make-gas.com: Redone to work with new scheme.
4405 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4407 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4408 will swap bytes if needed on a big endian system. Use throughout
4410 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4411 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4412 types of malformed stabs. Change parsing algorithm so that we are
4413 more certain of having all of the information that we need on hand.
4414 * obj-vms.c (final_forward_reference): New function, used to help
4415 resolve the data types of as many struct elements as possible
4416 when some part of the struct is not fully defined by the compiler.

4419 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4420 as symbols as well in the object file. Look for external functions
4421 that start with "__vt.", and turn them into variables, since the
4422 g++ compiler is incapable of doing this.
4423 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4425 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4426 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4427 have the name of the source file yet.
4428 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4430 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4432 * read.c (s_data): Always use "data_section", since it'll map to
4433 SEG_DATA or SEG_E1 if needed.
4434 (s_lcomm): Likewise with bss_section.
4435 (s_fill): Use memset, not bzero.
4437 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4458 (section_alignment): Declare only if not BFD_ASSEMBLER.
4459 (big_section, reg_section, pass1_section, diff_section,
4460 absent_section, text_section, data_section, bss_section): If
4461 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4462 mapping to segT enum values.
4463 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4464 if these are used or defined, if BFD_ASSEMBLER.
4465 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4466 subseg_new split into two functions.
4467 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4469 * as.h (volatile): Don't define if already defined.
4470 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4472 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4473 declare with format attribute for -Wformat checking.
4475 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4477 * app.c, config/tc-*.c: Don't include read.h, since it is already
4480 * These are based on patches from Minh Tran-le
4481 <mtranle@paris.intellicorp.com>.
4482 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4483 obj_format coffbfd and gas_target i386coff for target.
4484 (i[34]86-*-isc*): New host (uses sysv).
4485 * config/i386aix.mt: Removed (no longer used).
4486 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4488 (LDFLAGS): Added, defined as -shlib.
4489 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4490 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4491 (DOT_LABEL_PREFIX): Define.
4492 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4493 name rather than L0\001.
4494 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4496 * symbols.c, symbols.h (local_bss_counter): Removed.
4497 * write.c (write_object_file): bss no longer uses
4498 local_bss_counter. Pass correct data and bss size to
4499 VMS_write_object_file.

4505 (size_section): Restored sanity check.
4506 (do_relocs_for): Base section address on s_paddr rather than
4507 computing it. Adjust a29k R_IHIHALF special case to account for
4508 section paddr (used to require paddr to be zero). If there are no
4509 reclos, set s_relptr to 0. Set relocation size in object_headers.
4510 (fill_section): Always set s_vaddr here, removing
4511 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4512 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4513 Set STYP_INFO for .comment.
4514 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4515 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4517 H_{SET,GET}_* macros.
4518 (do_linenos_for): Set lineno size in object_headers.
4519 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4520 set s_vaddr here. If string_byte_count remains 4, set it back to
4521 0, and only write strings out if there are some. Call
4522 fill_section before do_relocs_for and do_linenos_for.
4523 (obj_coff_section): Handle optional quoted second argument giving
4524 section characteristics.
4525 (obj_coff_bss): Added to handle .bss.
4526 (obj_coff_ident): Added to handle .ident (puts string in .comment
4528 (obj_coff_lcomm): Put common symbols in .bss, not .data.
4529 (fixup_mdeps): Change to segment. Call frag_wane after
4531 (fixup_segment): Explicitly check S_IS_COMMON before making 386
4532 adjustment (already happened only for common symbols, but this is

4546 (do_scrub_next_char): For \", return " not '.
4547 (symbol_chars): Now const.
4549 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4550 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4552 * config/obj-coff.h: Don't use #elif.
4554 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4555 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4557 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4559 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4579 SEG_BSS, fill with NOP_OPCODE.
4580 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
4581 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4582 using ZERO_BASED_SEGMENTS.
4583 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4584 never set segment address for SEG_E2 (.bss) and don't write out
4585 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4586 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4587 definitions, and don't merge tags with non-tags. Check for .bf
4588 rather than just checking whether the second character is b and
4589 the third character is f.
4590 (obj_coff_val): gcc can generate values which we don't handle
4591 correctly; discard information for now, since it only affects the
4592 debugging information.
4593 (tag_find_or_name): Don't insert tags in the symbol table.
4594 (yank_symbols): Don't merge labels.
4595 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4650 options. Updated options documentation for m68k. Some minor
4651 wording/punctuation changes.

4734 GNU `indent'. Some cleanup still needed, especially of comments.
4736 * configure.in: No te-386bsd.h file exists; don't try to use it.
4738 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
4740 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
4741 could be doing emulation.
4743 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4746 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4773 consistently const, and always initialized them. Included read.h.
4775 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4777 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4778 constant will not fit in an immediate field.
4779 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
4781 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
4783 * obj-coff.c (callj_table): Delete global variable.

4790 * obj-coff.c: Replaced ANSI and non-ANSI function declarations
4791 with a single set using PARAMS macro.
4793 * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length

4798 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
4799 so widening works consistently.
4801 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
4803 * version.c: Put conditional "const" before version_string, not
4804 before dummy function for VMS. Now version 1.91.03.
4806 * app.c (do_scrub_next_char): Need double-\ before `000' to show
4807 printed rep of null character.
4809 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
4811 * obj-coffbfd.c (write_object_file): check return value of
4814 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4816 * Support for i386-sysv.
4817 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
4818 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
4819 be used to set them all to zero as was done before.

4821 (fill_section): Don't set STYP_NOLOAD for .bss section.
4822 (fixup_segment): 386 uses strange common symbol format.
4823 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
4824 compatibility with SVR3.2 linker.
4825 * configure.in: i386-sysv and i386-sco use coffbfd.
4827 * app.c (do_scrub_next_char): discard whitespace after a label.

4841 * tc-m68k.c (get_num): make it work for all segments, not just the
4844 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
4846 * configure.in: recognize i386-*-bsd emulation.

4855 * tc-z8k.c: lots of bug fixes
4857 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4859 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4860 #elif, since it is not supported by old compilers.
4861 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4862 couple of expressions in tc-m68k.c.
4864 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4866 * read.c (cons): If NO_RELOC is defined, use it.
4868 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4870 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4872 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4873 local labels to start with a .) and set REGISTER_PREFIX to %.
4874 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4876 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

4890 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4892 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4893 sections starting from zero, rather than making them consecutive.
4894 This makes subsequent reloc calculations easier, esp if the object
4895 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4896 allocate lcomm in .data rather than in .bss. It seems that some
4897 tools can't cope with a non-zero sized bss before linkage.
4899 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4901 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
4902 throughout. That enum no longer means what we thought it meant.

4905 "-mno-688[58]1" options.
4907 * tc-m68k.c: Added CPU32 support.

4916 Change LIBDEPS dependence to LIBS.
4918 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
4920 * Makefile.in (install): if $(tooldir) exists, install as in
4923 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4925 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4926 .word is < -32768 or > 32767. The -J flag causes the error to be
4927 ignored. This is to catch over-sized switches generated by gcc on
4928 systems which don't support the broken .word hack.
4929 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4930 write.c (fixup_segment): check for signed .word overflow if
4931 WARN_SIGNED_OVERFLOW_WORD.
4933 * write.c (fixup_segment): fixed missing parens in expression
4934 checking for byte or word overflow.
4936 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

4948 * tc-i386.h : new coff defines
4950 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4952 * input-scrub.c (input_scrub_push): call input_file_begin, not
4954 messages.c (as_perror): print ": " between the passed in error and
4955 the strerror, like perror does.
4957 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
4959 * Makefile.in: use gas_target instead of modifying target_cpu.
4960 From Steve Chamberlain:
4961 Makefile.in: Handle m68*-*-coff*.
4962 read.c, read.h: add mult argument to s_space
4964 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4965 Motorola and MIT syntax; gas can now assemble either type of
4967 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
4968 From Steve Chamberlain:
4969 m68kcoff.mt: for m68k COFF.
4970 obj-coffbfd.c: (fixup_mdeps) added

4973 (write_object_file) call fixup_mdeps
4974 (fixup_segment) set fx_subsy to 0.
4975 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4977 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4980 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4982 * Makefile.in (LIBS): Include opcode library.
4984 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

5004 tc-i960.c (md_ri_to_chars): Always output bout object file in
5005 little endian byte order (used to use endianness of host).
5007 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5009 * config/tc-m68k.c (init_table): Now const. Always include 68851
5010 data, so that "bc" is available to 68040 cache instructions.
5011 Added "tt0", "tt1", and 68ec030 variants.
5012 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5013 (enum _register): Added TT0, TT1.
5014 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5015 line number correctly in "internal error" messages. Don't print
5016 architecture-mismatch message for operand errors.
5018 From Colin Smith (colin@wrs.com):
5019 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5020 than install_operand.

5024 * listing.c (buffer_line): rewind to the start of include
5025 files, they might be included twice.

5032 one element of a family.
5034 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
5036 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5037 so that we can assemble hand-written libgcc code.
5039 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5041 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5042 has already been formatted (but may still contain %-characters).
5045 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5047 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5048 written with indirection on the last two operands, which can be
5049 either data or address registers. Added a new operand type 'r'
5050 which accepts either register type. Added '(' to notend stuff in
5051 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
5053 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

5067 (relax_align): If linkrelax, provide extra padding.
5069 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
5070 their not having symbols associated.
5072 * tc-i960.c (norelax, instrument_branches): Default initializer is
5074 (linkrelax): Delete variable definition.

5097 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
5098 being used with args swapped, causing occasional lossage when
5099 refilling buffers after an include file.
5101 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
5103 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
5104 version. Discard bogus DONTDEF version.
5105 (as_warn, as_bad, as_fatal): Likewise.
5107 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
5109 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
5110 selected architecture, print a message saying so and listing what

5128 if TN_SUN3; otherwise align to 2**N-byte bounary.
5130 Thu Aug 6 12:10:39 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5132 * read.c (s_fill): make the .fill size clamped error a warn and
5133 fix bug where 0's were always placed.
5135 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
5136 two bytes of any constant with 0xff:

5140 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
5141 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.

5155 * configure.in (mips host): Accept "ultrix" with version number.
5157 * expr.c (floating_constant): Separate "=-" to avoid confusing
5158 ancient or broken compilers.
5160 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
5161 processor/opcode mismatch, so reword the error message.
5162 (md_assemble): If no CPU has been set (even if FPU/PMMU
5163 characteristics have been), default to 68020. Don't need extra
5164 quotes around error string.
5166 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5168 * read.c (potable): Revert sac's incorrect change made Jul 13.

5246 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
5248 * write.c (write_object_file): keep the fix_tail clean, which
5249 fixes a bug in -R where relocations were being lost.
5251 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5253 * configure.in: recognize m680x0 as having sun3 emulation mode for

5279 calc the base of relocs correctly.
5280 * tc-a29k.c (parse_operand): allow expressions to be in any section.
5282 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)

5298 start addresses to match required alignment.
5300 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5302 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5303 where gcc looks for it.
5305 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5307 * Makefile.in: Changed some lines to be less confusing for some

5373 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5375 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5377 * expr.c (operand): if can't work out what sort of operand it is,
5378 then look through FLT_CHARS for a hint.
5380 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5382 * Makefile.in, configure.in: removed traces of namesubdir,
5383 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5384 copyrights to '92, changed some from Cygnus to FSF.
5386 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5387 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5388 copyrights to '92, changed some from Cygnus to FSF.
5390 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5392 * expr.c: If an expression is single comma, then return with
5393 SEG_ABSENT rather than an error - since the sparc front end does
5394 really strange things with things like fbge,a
5396 * as.h: include bfd.h if using many sections
5397 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5398 local labels didn't work.
5399 * listing.c (list_symbol_table): don't core dump when there's no
5401 * write.c, write.h: call fix_new with the right number of args on
5403 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5406 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5408 * app.c: MRI compatibility - allow single quote to start a string.
5409 * as.c: fix typo recently introduced.
5410 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5411 * expr.c: Much rewriting, to accomodate MRI syntax for
5412 expressions. Also easier to read now.
5413 * listing.c: Put back defuns
5414 * read.c: modified to accept MRI syntax, put back listing pseudo
5415 ops so that an assembler built with NO_LISTING ignores list ops
5417 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5418 machine is a SPARC or a 29K.
5419 * config/obj-aout.c: added s_sect pseudo op
5420 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5421 fill in the timestamp.
5422 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5423 anymore, define all the relocs which the tc-<x> bit will use so we
5424 can translate from them to the coff types.
5425 * config/tc-a29k.c: reloc_type isn't ane enum any more
5426 * config/tc-m68k.c: Added NO_RELOC definition.
5428 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5430 * Makefile.in: put header files before C source for TAGS; remove
5431 references to non-existent syscalls.h.
5433 * read.c, write.c subsegs.c: back out the .bss changes.
5435 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5437 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5441 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5443 * symbols.c (local_label_name): symbols now start with ^A.
5445 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5446 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5447 generate these sections. .align: will use NOP_OPCODE or 0
5448 for padding. This is just for being nice to the
5451 * expr.c (operand): changed to generate local label "\001L0"
5452 starting with a ^A so that it is recognized as a local label.
5454 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5456 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5457 i/o opcodes - inb, inw, outb and outw. string manipulation with
5458 att syntax - scmp, slod, smov, ssca, ssto.
5460 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5461 to just after .file .
5463 In obj_crawl_symbol_chain() where it tries to put the external
5464 symbols apart, with the condition:
5465 (!S_IS_DEFINED(symbolP) &&
5466 !S_IS_DEBUG(symbolP) &&
5467 !SF_GET_STATICS(symbolP))
5468 it was moving too many symbols out. So I switch it back to the
5470 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5472 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5473 so that we don't use the F_RELFLG which make the linker complain
5474 that somebody has stripped the relocation info.
5476 Also, the AIX ld program require that the relocation table
5477 is sorted by r_vaddr like the standard ATT assembler does.
5479 [he also changed the sizeof(struct ...)'s into the coff
5480 style FOOSZ macros. I'm not sure this is right, but I can't
5481 remember why. xoxorich.]
5483 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5485 * Makefile.in, configure.in, doc: use the doc. Build it, install
5488 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5490 * read.c: white space and comments only.
5492 * configure.in: use the new atof-ns32.c for ns32k.
5494 * write.c: comment change only.
5496 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5497 aren't yet integrated.
5499 * tc-i860.[hc]: blew off the dust. Something must still be done
5500 about conflicting relocation types.
5502 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5505 * tc-i960.c, tc-sparc.c: white space and comments only.
5507 * tc-a29k.h: delete duplicate macro definition.
5509 * new file atof-ns32k.c copied from hack's last unreleased gas.
5511 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5513 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5516 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5517 ChangeLog's prior to this are sketchy at best. I have logs.
5518 They just aren't ChangeLogs.
