1517 pass new argument for i, j and o cases.
1518 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

1520 (mips_ip, tc_get_register, s_frame): Use macros FP, SP, GP and AT
1521 rather than hard coded constants.
1522 (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and

1739 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
1740 the table, require that the one without bit 0x1000000 set come

1852 for keeping or rejecting configurations still under development;
1853 default is to assume production environment, and reject configs
1854 still being worked on. Mark Elf configurations (except sparc and
1855 i386) as developmental. Deleted cases matching some generic names
1856 in favor of more specific names. (E.g., when we get Alpha
1857 support, we'll still only support VMS for Vax.)

1860 * config/tc-sparc.c (md_end): Function deleted.
1861 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

1871 against placing additional object-file dependent code here. Warn
1872 against contaminating all of GAS with the internals of tc-hppa.c
1873 through inclusion of tc-hppa.h. Delete all forward declarations
1874 for functions only used within tc-hppa.c, likewise for structures,
1875 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1876 conditional code in a few small places.
1878 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1879 structures, global variables, forward declarations together.

1881 conditional code -- try to group conditional code together
1882 into a few places. Make all functions and variables which
1883 are only used within tc-hppa.c static. PARAMize all functions.
1884 Add comments to functions. Delete unused functions, variables,
1885 #defines, etc. Delete unused members within structures. Delete
1886 ldil;ble hacks -- it is believed they were installed to work
1887 around old gas bugs. Avoid using mixed case for local
1888 functions, variables, and structures. Fix formatting problems
1889 not found by GNU-indent. Add FIXME notices for things which
1890 should be worked on the near future. Delete lots of old
1891 useless (1.36 PA-SOM) code.
1893 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
1894 field of the fixS structure. Needed to build unwind

1920 a multiple of the section alignment rather than always a
1923 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

3034 * Extensive changes to permit symbols to contain any expression
3035 type and to delay the computation of the expression until the
3036 value is actually needed. This permits setting symbols to values
3037 calculated based on object code size. Expressions were changed to
3038 no longer be in a section, to stop the overloading of segment and
3039 expression type that previously occurred.
3041 * as.c (big_section, pass1_section, diff_section, absent_section):
3043 (expr_section): Added (used for dummy symbols which hold

3127 (previous_section, previous_subsection): New vars.
3128 (obj_elf_section): Save current place in case DWARF code wants us
3129 to pop back to it. Handle unquoted section name as well as quoted
3130 section name. Don't crash on invalid strings.
3131 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

3153 calculating opP->isiz; this permits the expression size to be
3154 determined as well, later on.

3219 (omagic): Removed unused variable.
3221 * Preliminary support for m88k-coff.

3240 * Removed sy_forward and replaced it with an undefined expression
3241 as the value of a symbol.
3242 * struc-symbol.h (struct symbol): Removed sy_forward field. Added
3243 sy_resolved and sy_resolving single bit fields.
3244 * symbols.c (symbol_new): Don't initialize sy_forward field.
3245 (resolve_symbol_value): New function to adjust symbol value by
3246 fragment address, using recursion to resolve forward symbols.

3248 * read.c (pseudo_set): Set symbolP->sy_value to an undefined
3249 expression rather than setting symbolP->sy_forward.
3250 * write.c (write_object_file): Use resolve_symbol_value on
3251 symbols, keeping the common case (the old behaviour) inline.

4247 than ECOFF line number information.
4248 (obj_ecoff_stab): Accept non-zero values for stabs line number.

4280 * doc/as.texinfo: First pass at using new texinfo features --
4281 variables, conditional tests. Far from complete.

4309 dependencies are read, not when they are used).
4311 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
4312 a29k .bss section; the mondfe program doesn't like it.

4333 source directory, if that's not the current directory.
4335 * configure.in (per-host): Accept MIPS host with BSD version

4357 process relocs if there aren't any relocs to process. Avoids
4358 malloc/free bug on SCO too.
4360 * as.h: Move local include files below system include files, to
4361 avoid some redefinition complaints on some systems.
4362 (const, volatile): Don't need these conditionally defined if we
4363 use CONST and VOLATILE from ansidecl.h.
4364 (seg_name): Use CONST, not const.
4366 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4368 * config/tc-mips.c: Reindented to GNU standards.

4372 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4373 (fixup_segment): Add a29k special case; the linker is not prepared
4374 to see a segment offset here.
4376 * app.c (do_scrub_next_char): Added new state, 10, modifying state

4379 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4381 * Makefile.in: add dvi target; as-$(config).texinfo might live in

4397 bignums, but don't emit error message.
4399 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
4401 * Makefile.in (targ-cpu.o): Depend on config.h.
4403 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4405 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4406 dropping a space immediately following an identifier.
4407 * expr.c, write.c: Rewrote assert expressions to not use multiple
4408 lines; I don't think that can be done portably.
4409 * config/tc-mips.c (macro): Use $AT if target register is zero in
4410 load instruction, which it can be for a floating point load.
4412 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4433 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4435 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4436 to be on a single line.
4438 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

4484 prototypes for all static functions. Moved existing minimal
4485 debugging format support info #ifndef OBJ_ECOFF blocks.
4486 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
4487 does not support a non sign extended high 16 bits reloc. Adjusted
4488 all callers accordingly.
4489 (tc_get_register): Renamed from get_register, and made non-static.
4491 * config/mips-big.mt, config/mips-lit.mt: New files. Define

4534 * make-gas.com: Find obstack.obj if it's not in the current
4536 * read.c (s_ignore): Don't declare is_end_of_line. It's
4537 redundant, and triggers a VMS gcc compiler bug.
4539 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4540 current segment as an argument. (Ignored in all cases but VMS.)
4541 All callers and definitions changed.

4672 for now; should be machine-dependent.
4674 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
4675 targets, forcing BFD use.

4838 md_relax_table): Use default zero initialization.
4839 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4840 latter, instead of selecting with preprocessor conditionals.
4842 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4844 * configure.in: recognise all sparclite variants

4854 * expr.c (operand): If character other than comma or newline is a
4855 logical end-of-line character, use the newline case.
4856 From Eric Youngdale:
4857 (operand): Set X_add_number field for floating-point numbers.
4858 (operand): Treat zero byte as end-of-operand.
4860 * configure.in (per-target): Look for with_bfd_assembler option.
4861 For now, only accept "no", until the merge is done.
4863 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4864 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4870 * expr.c: Add "const" modifier to hex_value.
4871 * symbols.c: Finish conversion to S_* macros in the VMS only
4872 parts of the program. Add "const" modifier to
4873 md_[long,short]_jump_size. Remove declaration of const_flag
4874 (which will be declared in obj-vms.h).
4875 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4876 Fix arguments to VMS_write_object_file.
4877 * config-gas.com: New file. Script for VMS systems to set up the
4878 configuration to build gas for VMS, and create config.status.
4879 * make-gas.com: Redone to work with new scheme.
4880 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4882 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4883 will swap bytes if needed on a big endian system. Use throughout
4885 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4886 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4887 types of malformed stabs. Change parsing algorithm so that we are
4888 more certain of having all of the information that we need on hand.
4889 * obj-vms.c (final_forward_reference): New function, used to help
4890 resolve the data types of as many struct elements as possible

4894 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4895 as symbols as well in the object file. Look for external functions
4896 that start with "__vt.", and turn them into variables, since the
4897 g++ compiler is incapable of doing this.
4898 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4900 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4901 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4902 have the name of the source file yet.
4903 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4905 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4907 * read.c (s_data): Always use "data_section", since it'll map to
4908 SEG_DATA or SEG_E1 if needed.
4909 (s_lcomm): Likewise with bss_section.
4910 (s_fill): Use memset, not bzero.
4912 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4933 (section_alignment): Declare only if not BFD_ASSEMBLER.
4934 (big_section, reg_section, pass1_section, diff_section,
4935 absent_section, text_section, data_section, bss_section): If
4936 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4937 mapping to segT enum values.
4938 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4939 if these are used or defined, if BFD_ASSEMBLER.
4940 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4941 subseg_new split into two functions.
4942 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4944 * as.h (volatile): Don't define if already defined.
4945 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4947 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4948 declare with format attribute for -Wformat checking.
4950 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4952 * app.c, config/tc-*.c: Don't include read.h, since it is already
4955 * These are based on patches from Minh Tran-le
4956 <mtranle@paris.intellicorp.com>.
4957 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4958 obj_format coffbfd and gas_target i386coff for target.
4959 (i[34]86-*-isc*): New host (uses sysv).
4960 * config/i386aix.mt: Removed (no longer used).
4961 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4963 (LDFLAGS): Added, defined as -shlib.
4964 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4965 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4966 (DOT_LABEL_PREFIX): Define.
4967 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4968 name rather than L0\001.
4969 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4971 * symbols.c, symbols.h (local_bss_counter): Removed.
4972 * write.c (write_object_file): bss no longer uses

4980 (size_section): Restored sanity check.
4981 (do_relocs_for): Base section address on s_paddr rather than
4982 computing it. Adjust a29k R_IHIHALF special case to account for
4983 section paddr (used to require paddr to be zero). If there are no
4984 reclos, set s_relptr to 0. Set relocation size in object_headers.
4985 (fill_section): Always set s_vaddr here, removing
4986 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4987 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4988 Set STYP_INFO for .comment.

4992 H_{SET,GET}_* macros.
4993 (do_linenos_for): Set lineno size in object_headers.
4994 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4995 set s_vaddr here. If string_byte_count remains 4, set it back to
4996 0, and only write strings out if there are some. Call
4997 fill_section before do_relocs_for and do_linenos_for.
4998 (obj_coff_section): Handle optional quoted second argument giving
4999 section characteristics.
5000 (obj_coff_bss): Added to handle .bss.
5001 (obj_coff_ident): Added to handle .ident (puts string in .comment

5021 (do_scrub_next_char): For \", return " not '.
5022 (symbol_chars): Now const.
5024 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5025 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5027 * config/obj-coff.h: Don't use #elif.
5029 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5030 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5032 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5034 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5056 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5057 using ZERO_BASED_SEGMENTS.
5058 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5059 never set segment address for SEG_E2 (.bss) and don't write out
5060 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5061 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5062 definitions, and don't merge tags with non-tags. Check for .bf
5063 rather than just checking whether the second character is b and
5064 the third character is f.
5065 (obj_coff_val): gcc can generate values which we don't handle
5066 correctly; discard information for now, since it only affects the
5067 debugging information.
5068 (tag_find_or_name): Don't insert tags in the symbol table.
5069 (yank_symbols): Don't merge labels.
5070 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5208 * all files: Whitespace changes for GNU indentation style, done by
5209 GNU `indent'. Some cleanup still needed, especially of comments.
5211 * configure.in: No te-386bsd.h file exists; don't try to use it.
5213 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
5215 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
5216 could be doing emulation.
5218 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5221 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5248 consistently const, and always initialized them. Included read.h.
5250 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5252 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5253 constant will not fit in an immediate field.
5254 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
5256 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
5258 * obj-coff.c (callj_table): Delete global variable.

5273 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
5274 so widening works consistently.
5276 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
5278 * version.c: Put conditional "const" before version_string, not
5279 before dummy function for VMS. Now version 1.91.03.
5281 * app.c (do_scrub_next_char): Need double-\ before `000' to show
5282 printed rep of null character.
5284 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
5286 * obj-coffbfd.c (write_object_file): check return value of
5289 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5291 * Support for i386-sysv.
5292 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
5293 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
5294 be used to set them all to zero as was done before.

5296 (fill_section): Don't set STYP_NOLOAD for .bss section.
5297 (fixup_segment): 386 uses strange common symbol format.

5300 * configure.in: i386-sysv and i386-sco use coffbfd.
5302 * app.c (do_scrub_next_char): discard whitespace after a label.

5316 * tc-m68k.c (get_num): make it work for all segments, not just the
5319 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
5321 * configure.in: recognize i386-*-bsd emulation.

5330 * tc-z8k.c: lots of bug fixes
5332 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5334 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5335 #elif, since it is not supported by old compilers.
5336 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5337 couple of expressions in tc-m68k.c.
5339 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5341 * read.c (cons): If NO_RELOC is defined, use it.
5343 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5345 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5347 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5348 local labels to start with a .) and set REGISTER_PREFIX to %.
5349 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5351 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5365 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5367 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5368 sections starting from zero, rather than making them consecutive.
5369 This makes subsequent reloc calculations easier, esp if the object
5370 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5371 allocate lcomm in .data rather than in .bss. It seems that some
5372 tools can't cope with a non-zero sized bss before linkage.
5374 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5376 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
5377 throughout. That enum no longer means what we thought it meant.

5380 "-mno-688[58]1" options.
5382 * tc-m68k.c: Added CPU32 support.

5391 Change LIBDEPS dependence to LIBS.
5393 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
5395 * Makefile.in (install): if $(tooldir) exists, install as in
5398 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5400 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5401 .word is < -32768 or > 32767. The -J flag causes the error to be
5402 ignored. This is to catch over-sized switches generated by gcc on
5403 systems which don't support the broken .word hack.
5404 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5405 write.c (fixup_segment): check for signed .word overflow if
5406 WARN_SIGNED_OVERFLOW_WORD.
5408 * write.c (fixup_segment): fixed missing parens in expression
5409 checking for byte or word overflow.
5411 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
5412 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
5413 WARN_SIGNED_OVERFLOW_WORD.

5423 * tc-i386.h : new coff defines
5425 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5427 * input-scrub.c (input_scrub_push): call input_file_begin, not
5429 messages.c (as_perror): print ": " between the passed in error and
5430 the strerror, like perror does.
5432 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
5434 * Makefile.in: use gas_target instead of modifying target_cpu.
5435 From Steve Chamberlain:
5436 Makefile.in: Handle m68*-*-coff*.
5437 read.c, read.h: add mult argument to s_space
5439 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5440 Motorola and MIT syntax; gas can now assemble either type of
5442 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
5443 From Steve Chamberlain:
5444 m68kcoff.mt: for m68k COFF.
5445 obj-coffbfd.c: (fixup_mdeps) added

5448 (write_object_file) call fixup_mdeps
5449 (fixup_segment) set fx_subsy to 0.
5450 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5452 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5455 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5457 * Makefile.in (LIBS): Include opcode library.
5459 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

5479 tc-i960.c (md_ri_to_chars): Always output bout object file in
5480 little endian byte order (used to use endianness of host).
5482 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5484 * config/tc-m68k.c (init_table): Now const. Always include 68851
5485 data, so that "bc" is available to 68040 cache instructions.
5486 Added "tt0", "tt1", and 68ec030 variants.
5487 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5488 (enum _register): Added TT0, TT1.
5489 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5490 line number correctly in "internal error" messages. Don't print
5491 architecture-mismatch message for operand errors.
5493 From Colin Smith (colin@wrs.com):
5494 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5495 than install_operand.

5499 * listing.c (buffer_line): rewind to the start of include
5500 files, they might be included twice.

5507 one element of a family.
5509 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
5511 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5512 so that we can assemble hand-written libgcc code.
5514 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5516 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5517 has already been formatted (but may still contain %-characters).
5520 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5522 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5523 written with indirection on the last two operands, which can be
5524 either data or address registers. Added a new operand type 'r'
5525 which accepts either register type. Added '(' to notend stuff in
5526 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
5528 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

5544 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
5545 their not having symbols associated.
5547 * tc-i960.c (norelax, instrument_branches): Default initializer is
5549 (linkrelax): Delete variable definition.

5572 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
5573 being used with args swapped, causing occasional lossage when
5574 refilling buffers after an include file.
5576 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
5578 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
5579 version. Discard bogus DONTDEF version.
5580 (as_warn, as_bad, as_fatal): Likewise.

5584 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
5585 selected architecture, print a message saying so and listing what

5607 * read.c (s_fill): make the .fill size clamped error a warn and
5608 fix bug where 0's were always placed.
5610 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
5611 two bytes of any constant with 0xff:

5630 * configure.in (mips host): Accept "ultrix" with version number.
5632 * expr.c (floating_constant): Separate "=-" to avoid confusing
5633 ancient or broken compilers.
5635 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
5636 processor/opcode mismatch, so reword the error message.
5637 (md_assemble): If no CPU has been set (even if FPU/PMMU
5638 characteristics have been), default to 68020. Don't need extra
5639 quotes around error string.
5641 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5643 * read.c (potable): Revert sac's incorrect change made Jul 13.

5721 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
5723 * write.c (write_object_file): keep the fix_tail clean, which
5724 fixes a bug in -R where relocations were being lost.

5775 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5777 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5778 where gcc looks for it.
5780 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5782 * Makefile.in: Changed some lines to be less confusing for some

5848 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5850 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5852 * expr.c (operand): if can't work out what sort of operand it is,
5853 then look through FLT_CHARS for a hint.
5855 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5857 * Makefile.in, configure.in: removed traces of namesubdir,

5859 copyrights to '92, changed some from Cygnus to FSF.
5861 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5862 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5863 copyrights to '92, changed some from Cygnus to FSF.
5865 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5867 * expr.c: If an expression is single comma, then return with
5868 SEG_ABSENT rather than an error - since the sparc front end does
5869 really strange things with things like fbge,a
5871 * as.h: include bfd.h if using many sections
5872 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5873 local labels didn't work.
5874 * listing.c (list_symbol_table): don't core dump when there's no
5876 * write.c, write.h: call fix_new with the right number of args on
5878 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5881 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5883 * app.c: MRI compatibility - allow single quote to start a string.
5884 * as.c: fix typo recently introduced.
5885 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5886 * expr.c: Much rewriting, to accomodate MRI syntax for
5887 expressions. Also easier to read now.
5888 * listing.c: Put back defuns
5889 * read.c: modified to accept MRI syntax, put back listing pseudo
5890 ops so that an assembler built with NO_LISTING ignores list ops
5892 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5893 machine is a SPARC or a 29K.
5894 * config/obj-aout.c: added s_sect pseudo op
5895 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5896 fill in the timestamp.
5897 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5898 anymore, define all the relocs which the tc-<x> bit will use so we
5899 can translate from them to the coff types.
5900 * config/tc-a29k.c: reloc_type isn't ane enum any more
5901 * config/tc-m68k.c: Added NO_RELOC definition.
5903 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5905 * Makefile.in: put header files before C source for TAGS; remove
5906 references to non-existent syscalls.h.
5908 * read.c, write.c subsegs.c: back out the .bss changes.
5910 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5912 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5916 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5918 * symbols.c (local_label_name): symbols now start with ^A.
5920 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5921 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5922 generate these sections. .align: will use NOP_OPCODE or 0
5923 for padding. This is just for being nice to the
5926 * expr.c (operand): changed to generate local label "\001L0"
5927 starting with a ^A so that it is recognized as a local label.
5929 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5931 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5932 i/o opcodes - inb, inw, outb and outw. string manipulation with
5933 att syntax - scmp, slod, smov, ssca, ssto.
5935 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5936 to just after .file .
5938 In obj_crawl_symbol_chain() where it tries to put the external
5939 symbols apart, with the condition:
5940 (!S_IS_DEFINED(symbolP) &&
5941 !S_IS_DEBUG(symbolP) &&
5942 !SF_GET_STATICS(symbolP))
5943 it was moving too many symbols out. So I switch it back to the
5945 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5947 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5948 so that we don't use the F_RELFLG which make the linker complain
5949 that somebody has stripped the relocation info.
5951 Also, the AIX ld program require that the relocation table
5952 is sorted by r_vaddr like the standard ATT assembler does.
5954 [he also changed the sizeof(struct ...)'s into the coff
5955 style FOOSZ macros. I'm not sure this is right, but I can't
5956 remember why. xoxorich.]
5958 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5960 * Makefile.in, configure.in, doc: use the doc. Build it, install
5963 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5965 * read.c: white space and comments only.
5967 * configure.in: use the new atof-ns32.c for ns32k.
5969 * write.c: comment change only.
5971 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5972 aren't yet integrated.
5974 * tc-i860.[hc]: blew off the dust. Something must still be done
5975 about conflicting relocation types.
5977 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5980 * tc-i960.c, tc-sparc.c: white space and comments only.
5982 * tc-a29k.h: delete duplicate macro definition.
5984 * new file atof-ns32k.c copied from hack's last unreleased gas.
5986 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5988 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5991 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5992 ChangeLog's prior to this are sketchy at best. I have logs.
5993 They just aren't ChangeLogs.
