1512 pass new argument for i, j and o cases.
1513 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

1734 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
1735 the table, require that the one without bit 0x1000000 set come

1847 for keeping or rejecting configurations still under development;
1848 default is to assume production environment, and reject configs
1849 still being worked on. Mark Elf configurations (except sparc and
1850 i386) as developmental. Deleted cases matching some generic names
1851 in favor of more specific names. (E.g., when we get Alpha

1866 against placing additional object-file dependent code here. Warn
1867 against contaminating all of GAS with the internals of tc-hppa.c
1868 through inclusion of tc-hppa.h. Delete all forward declarations
1869 for functions only used within tc-hppa.c, likewise for structures,
1870 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1871 conditional code in a few small places.
1873 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group

1877 into a few places. Make all functions and variables which
1878 are only used within tc-hppa.c static. PARAMize all functions.
1879 Add comments to functions. Delete unused functions, variables,
1880 #defines, etc. Delete unused members within structures. Delete
1881 ldil;ble hacks -- it is believed they were installed to work
1882 around old gas bugs. Avoid using mixed case for local
1883 functions, variables, and structures. Fix formatting problems
1884 not found by GNU-indent. Add FIXME notices for things which
1885 should be worked on the near future. Delete lots of old
1886 useless (1.36 PA-SOM) code.

3029 * Extensive changes to permit symbols to contain any expression
3030 type and to delay the computation of the expression until the
3031 value is actually needed. This permits setting symbols to values
3032 calculated based on object code size. Expressions were changed to
3033 no longer be in a section, to stop the overloading of segment and
3034 expression type that previously occurred.
3036 * as.c (big_section, pass1_section, diff_section, absent_section):
3038 (expr_section): Added (used for dummy symbols which hold

3148 calculating opP->isiz; this permits the expression size to be
3149 determined as well, later on.

3235 * Removed sy_forward and replaced it with an undefined expression
3236 as the value of a symbol.
3237 * struc-symbol.h (struct symbol): Removed sy_forward field. Added
3238 sy_resolved and sy_resolving single bit fields.
3239 * symbols.c (symbol_new): Don't initialize sy_forward field.

3243 * read.c (pseudo_set): Set symbolP->sy_value to an undefined
3244 expression rather than setting symbolP->sy_forward.
3245 * write.c (write_object_file): Use resolve_symbol_value on
3246 symbols, keeping the common case (the old behaviour) inline.
3247 * config/obj-aout.c (obj_aout_frob_symbol): Removed sy_forward
3248 handling (subsumed by write.c change).
3249 * config/obj-coff.c, config/obj-coffbfd.c (obj_coff_val): Set

4242 than ECOFF line number information.
4243 (obj_ecoff_stab): Accept non-zero values for stabs line number.

4275 * doc/as.texinfo: First pass at using new texinfo features --
4276 variables, conditional tests. Far from complete.

4304 dependencies are read, not when they are used).
4306 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
4307 a29k .bss section; the mondfe program doesn't like it.

4328 source directory, if that's not the current directory.
4330 * configure.in (per-host): Accept MIPS host with BSD version

4352 process relocs if there aren't any relocs to process. Avoids
4353 malloc/free bug on SCO too.
4355 * as.h: Move local include files below system include files, to
4356 avoid some redefinition complaints on some systems.
4357 (const, volatile): Don't need these conditionally defined if we
4358 use CONST and VOLATILE from ansidecl.h.
4359 (seg_name): Use CONST, not const.
4361 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4363 * config/tc-mips.c: Reindented to GNU standards.

4367 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4368 (fixup_segment): Add a29k special case; the linker is not prepared
4369 to see a segment offset here.
4371 * app.c (do_scrub_next_char): Added new state, 10, modifying state

4374 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4376 * Makefile.in: add dvi target; as-$(config).texinfo might live in

4392 bignums, but don't emit error message.
4394 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
4396 * Makefile.in (targ-cpu.o): Depend on config.h.
4398 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4400 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4401 dropping a space immediately following an identifier.
4402 * expr.c, write.c: Rewrote assert expressions to not use multiple
4403 lines; I don't think that can be done portably.
4404 * config/tc-mips.c (macro): Use $AT if target register is zero in
4405 load instruction, which it can be for a floating point load.
4407 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4428 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4430 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4431 to be on a single line.
4433 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4435 * Makefile.in (config.h): Create file, writing out definitions of

4479 prototypes for all static functions. Moved existing minimal
4480 debugging format support info #ifndef OBJ_ECOFF blocks.
4481 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
4482 does not support a non sign extended high 16 bits reloc. Adjusted
4483 all callers accordingly.
4484 (tc_get_register): Renamed from get_register, and made non-static.
4486 * config/mips-big.mt, config/mips-lit.mt: New files. Define

4529 * make-gas.com: Find obstack.obj if it's not in the current
4531 * read.c (s_ignore): Don't declare is_end_of_line. It's
4532 redundant, and triggers a VMS gcc compiler bug.
4534 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4535 current segment as an argument. (Ignored in all cases but VMS.)
4536 All callers and definitions changed.

4833 md_relax_table): Use default zero initialization.
4834 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4835 latter, instead of selecting with preprocessor conditionals.
4837 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4839 * configure.in: recognise all sparclite variants

4849 * expr.c (operand): If character other than comma or newline is a
4850 logical end-of-line character, use the newline case.
4851 From Eric Youngdale:
4852 (operand): Set X_add_number field for floating-point numbers.
4853 (operand): Treat zero byte as end-of-operand.
4855 * configure.in (per-target): Look for with_bfd_assembler option.
4856 For now, only accept "no", until the merge is done.
4858 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4859 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4865 * expr.c: Add "const" modifier to hex_value.
4866 * symbols.c: Finish conversion to S_* macros in the VMS only
4867 parts of the program. Add "const" modifier to
4868 md_[long,short]_jump_size. Remove declaration of const_flag
4869 (which will be declared in obj-vms.h).
4870 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4871 Fix arguments to VMS_write_object_file.
4872 * config-gas.com: New file. Script for VMS systems to set up the
4873 configuration to build gas for VMS, and create config.status.
4874 * make-gas.com: Redone to work with new scheme.
4875 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4877 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4878 will swap bytes if needed on a big endian system. Use throughout
4880 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4881 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4882 types of malformed stabs. Change parsing algorithm so that we are
4883 more certain of having all of the information that we need on hand.
4884 * obj-vms.c (final_forward_reference): New function, used to help
4885 resolve the data types of as many struct elements as possible
4886 when some part of the struct is not fully defined by the compiler.

4889 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4890 as symbols as well in the object file. Look for external functions

4892 g++ compiler is incapable of doing this.
4893 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4895 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4896 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4897 have the name of the source file yet.
4898 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4900 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4902 * read.c (s_data): Always use "data_section", since it'll map to
4903 SEG_DATA or SEG_E1 if needed.
4904 (s_lcomm): Likewise with bss_section.
4905 (s_fill): Use memset, not bzero.
4907 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4928 (section_alignment): Declare only if not BFD_ASSEMBLER.
4929 (big_section, reg_section, pass1_section, diff_section,
4930 absent_section, text_section, data_section, bss_section): If
4931 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4932 mapping to segT enum values.
4933 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4934 if these are used or defined, if BFD_ASSEMBLER.
4935 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4936 subseg_new split into two functions.
4937 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4939 * as.h (volatile): Don't define if already defined.
4940 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4942 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4943 declare with format attribute for -Wformat checking.
4945 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4947 * app.c, config/tc-*.c: Don't include read.h, since it is already
4950 * These are based on patches from Minh Tran-le
4951 <mtranle@paris.intellicorp.com>.
4952 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4953 obj_format coffbfd and gas_target i386coff for target.
4954 (i[34]86-*-isc*): New host (uses sysv).
4955 * config/i386aix.mt: Removed (no longer used).
4956 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4958 (LDFLAGS): Added, defined as -shlib.
4959 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4960 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4961 (DOT_LABEL_PREFIX): Define.
4962 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4963 name rather than L0\001.
4964 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4966 * symbols.c, symbols.h (local_bss_counter): Removed.
4967 * write.c (write_object_file): bss no longer uses
4968 local_bss_counter. Pass correct data and bss size to

4975 (size_section): Restored sanity check.
4976 (do_relocs_for): Base section address on s_paddr rather than
4977 computing it. Adjust a29k R_IHIHALF special case to account for
4978 section paddr (used to require paddr to be zero). If there are no
4979 reclos, set s_relptr to 0. Set relocation size in object_headers.
4980 (fill_section): Always set s_vaddr here, removing
4981 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4982 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4983 Set STYP_INFO for .comment.
4984 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4985 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4987 H_{SET,GET}_* macros.
4988 (do_linenos_for): Set lineno size in object_headers.
4989 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4990 set s_vaddr here. If string_byte_count remains 4, set it back to
4991 0, and only write strings out if there are some. Call
4992 fill_section before do_relocs_for and do_linenos_for.
4993 (obj_coff_section): Handle optional quoted second argument giving
4994 section characteristics.
4995 (obj_coff_bss): Added to handle .bss.
4996 (obj_coff_ident): Added to handle .ident (puts string in .comment

5016 (do_scrub_next_char): For \", return " not '.
5017 (symbol_chars): Now const.
5019 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5020 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5022 * config/obj-coff.h: Don't use #elif.
5024 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5025 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5027 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5029 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5051 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5052 using ZERO_BASED_SEGMENTS.
5053 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5054 never set segment address for SEG_E2 (.bss) and don't write out
5055 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5056 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5057 definitions, and don't merge tags with non-tags. Check for .bf
5058 rather than just checking whether the second character is b and
5059 the third character is f.
5060 (obj_coff_val): gcc can generate values which we don't handle
5061 correctly; discard information for now, since it only affects the
5062 debugging information.
5063 (tag_find_or_name): Don't insert tags in the symbol table.
5064 (yank_symbols): Don't merge labels.
5065 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5203 * all files: Whitespace changes for GNU indentation style, done by
5204 GNU `indent'. Some cleanup still needed, especially of comments.
5206 * configure.in: No te-386bsd.h file exists; don't try to use it.
5208 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
5210 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
5211 could be doing emulation.
5213 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5216 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5243 consistently const, and always initialized them. Included read.h.
5245 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5247 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5248 constant will not fit in an immediate field.
5249 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
5251 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
5253 * obj-coff.c (callj_table): Delete global variable.

5268 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
5269 so widening works consistently.
5271 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
5273 * version.c: Put conditional "const" before version_string, not
5274 before dummy function for VMS. Now version 1.91.03.
5276 * app.c (do_scrub_next_char): Need double-\ before `000' to show
5277 printed rep of null character.
5279 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
5281 * obj-coffbfd.c (write_object_file): check return value of
5284 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5286 * Support for i386-sysv.
5287 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
5288 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
5289 be used to set them all to zero as was done before.
5290 (fill_section): segment addresses now set in write_object_file.
5291 (fill_section): Don't set STYP_NOLOAD for .bss section.
5292 (fixup_segment): 386 uses strange common symbol format.
5293 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
5294 compatibility with SVR3.2 linker.
5295 * configure.in: i386-sysv and i386-sco use coffbfd.
5297 * app.c (do_scrub_next_char): discard whitespace after a label.

5306 fix i960+non-bfd coff bit rot.
5307 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
5308 support for C source listings. (obj_coff_endef): look in the right
5309 part of the symbol for the symbol name
5311 * tc-m68k.c (get_num): make it work for all segments, not just the
5314 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
5316 * configure.in: recognize i386-*-bsd emulation.

5325 * tc-z8k.c: lots of bug fixes
5327 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5329 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5330 #elif, since it is not supported by old compilers.
5331 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5332 couple of expressions in tc-m68k.c.
5334 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5336 * read.c (cons): If NO_RELOC is defined, use it.
5338 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5340 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5342 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5343 local labels to start with a .) and set REGISTER_PREFIX to %.
5344 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5346 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5360 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5362 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5363 sections starting from zero, rather than making them consecutive.
5364 This makes subsequent reloc calculations easier, esp if the object
5365 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5366 allocate lcomm in .data rather than in .bss. It seems that some
5367 tools can't cope with a non-zero sized bss before linkage.
5369 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5371 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
5372 throughout. That enum no longer means what we thought it meant.

5388 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
5390 * Makefile.in (install): if $(tooldir) exists, install as in
5393 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5395 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5396 .word is < -32768 or > 32767. The -J flag causes the error to be
5397 ignored. This is to catch over-sized switches generated by gcc on
5398 systems which don't support the broken .word hack.
5399 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5400 write.c (fixup_segment): check for signed .word overflow if
5401 WARN_SIGNED_OVERFLOW_WORD.
5403 * write.c (fixup_segment): fixed missing parens in expression
5404 checking for byte or word overflow.
5406 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

5416 * obj-coffbfd.h : added stuff
5417 * tc-i386.c (tc_coff_fix2rtype): new function
5418 * tc-i386.h : new coff defines
5420 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5422 * input-scrub.c (input_scrub_push): call input_file_begin, not
5424 messages.c (as_perror): print ": " between the passed in error and
5425 the strerror, like perror does.
5427 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
5429 * Makefile.in: use gas_target instead of modifying target_cpu.
5430 From Steve Chamberlain:
5431 Makefile.in: Handle m68*-*-coff*.
5432 read.c, read.h: add mult argument to s_space
5434 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5435 Motorola and MIT syntax; gas can now assemble either type of
5437 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
5438 From Steve Chamberlain:
5439 m68kcoff.mt: for m68k COFF.
5440 obj-coffbfd.c: (fixup_mdeps) added

5443 (write_object_file) call fixup_mdeps
5444 (fixup_segment) set fx_subsy to 0.
5445 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5447 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5450 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5452 * Makefile.in (LIBS): Include opcode library.
5454 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

5474 tc-i960.c (md_ri_to_chars): Always output bout object file in
5475 little endian byte order (used to use endianness of host).
5477 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5479 * config/tc-m68k.c (init_table): Now const. Always include 68851
5480 data, so that "bc" is available to 68040 cache instructions.
5481 Added "tt0", "tt1", and 68ec030 variants.
5482 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5483 (enum _register): Added TT0, TT1.
5484 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5485 line number correctly in "internal error" messages. Don't print
5486 architecture-mismatch message for operand errors.
5488 From Colin Smith (colin@wrs.com):
5489 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5490 than install_operand.

5494 * listing.c (buffer_line): rewind to the start of include
5495 files, they might be included twice.

5502 one element of a family.
5504 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
5506 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5507 so that we can assemble hand-written libgcc code.
5509 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5511 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5512 has already been formatted (but may still contain %-characters).
5515 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5517 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5518 written with indirection on the last two operands, which can be
5519 either data or address registers. Added a new operand type 'r'
5520 which accepts either register type. Added '(' to notend stuff in
5521 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
5523 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

5539 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
5540 their not having symbols associated.
5542 * tc-i960.c (norelax, instrument_branches): Default initializer is
5544 (linkrelax): Delete variable definition.

5567 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
5568 being used with args swapped, causing occasional lossage when
5569 refilling buffers after an include file.
5571 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
5573 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
5574 version. Discard bogus DONTDEF version.

5579 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
5580 selected architecture, print a message saying so and listing what

5625 * configure.in (mips host): Accept "ultrix" with version number.
5627 * expr.c (floating_constant): Separate "=-" to avoid confusing
5628 ancient or broken compilers.
5630 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
5631 processor/opcode mismatch, so reword the error message.
5632 (md_assemble): If no CPU has been set (even if FPU/PMMU
5633 characteristics have been), default to 68020. Don't need extra
5634 quotes around error string.
5636 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5638 * read.c (potable): Revert sac's incorrect change made Jul 13.

5716 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
5718 * write.c (write_object_file): keep the fix_tail clean, which
5719 fixes a bug in -R where relocations were being lost.
5721 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5723 * configure.in: recognize m680x0 as having sun3 emulation mode for

5746 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5748 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
5749 calc the base of relocs correctly.
5750 * tc-a29k.c (parse_operand): allow expressions to be in any section.
5752 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
5754 * as.c, write.c: use -K rather than -k for the broken word warning

5767 * write.c (write_object_file): For b.out format, round up section
5768 start addresses to match required alignment.
5770 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5772 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5773 where gcc looks for it.
5775 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5777 * Makefile.in: Changed some lines to be less confusing for some

5817 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
5819 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

5843 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5845 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5847 * expr.c (operand): if can't work out what sort of operand it is,
5848 then look through FLT_CHARS for a hint.
5850 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5852 * Makefile.in, configure.in: removed traces of namesubdir,
5853 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5854 copyrights to '92, changed some from Cygnus to FSF.
5856 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5857 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5858 copyrights to '92, changed some from Cygnus to FSF.
5860 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5862 * expr.c: If an expression is single comma, then return with
5863 SEG_ABSENT rather than an error - since the sparc front end does
5864 really strange things with things like fbge,a
5866 * as.h: include bfd.h if using many sections
5867 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5868 local labels didn't work.
5869 * listing.c (list_symbol_table): don't core dump when there's no
5871 * write.c, write.h: call fix_new with the right number of args on
5873 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5876 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5878 * app.c: MRI compatibility - allow single quote to start a string.
5879 * as.c: fix typo recently introduced.
5880 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5881 * expr.c: Much rewriting, to accomodate MRI syntax for
5882 expressions. Also easier to read now.
5883 * listing.c: Put back defuns
5884 * read.c: modified to accept MRI syntax, put back listing pseudo
5885 ops so that an assembler built with NO_LISTING ignores list ops
5887 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5888 machine is a SPARC or a 29K.
5889 * config/obj-aout.c: added s_sect pseudo op
5890 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5891 fill in the timestamp.
5892 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5893 anymore, define all the relocs which the tc-<x> bit will use so we
5894 can translate from them to the coff types.
5895 * config/tc-a29k.c: reloc_type isn't ane enum any more
5896 * config/tc-m68k.c: Added NO_RELOC definition.
5898 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5900 * Makefile.in: put header files before C source for TAGS; remove
5901 references to non-existent syscalls.h.
5903 * read.c, write.c subsegs.c: back out the .bss changes.
5905 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5907 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5911 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5913 * symbols.c (local_label_name): symbols now start with ^A.
5915 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5916 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5917 generate these sections. .align: will use NOP_OPCODE or 0
5918 for padding. This is just for being nice to the
5921 * expr.c (operand): changed to generate local label "\001L0"
5922 starting with a ^A so that it is recognized as a local label.
5924 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5926 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5927 i/o opcodes - inb, inw, outb and outw. string manipulation with
5928 att syntax - scmp, slod, smov, ssca, ssto.
5930 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5931 to just after .file .
5933 In obj_crawl_symbol_chain() where it tries to put the external
5934 symbols apart, with the condition:
5935 (!S_IS_DEFINED(symbolP) &&
5936 !S_IS_DEBUG(symbolP) &&
5937 !SF_GET_STATICS(symbolP))
5938 it was moving too many symbols out. So I switch it back to the
5940 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5942 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5943 so that we don't use the F_RELFLG which make the linker complain
5944 that somebody has stripped the relocation info.
5946 Also, the AIX ld program require that the relocation table
5947 is sorted by r_vaddr like the standard ATT assembler does.
5949 [he also changed the sizeof(struct ...)'s into the coff
5950 style FOOSZ macros. I'm not sure this is right, but I can't
5951 remember why. xoxorich.]
5953 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5955 * Makefile.in, configure.in, doc: use the doc. Build it, install
5958 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5960 * read.c: white space and comments only.
5962 * configure.in: use the new atof-ns32.c for ns32k.
5964 * write.c: comment change only.
5966 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5967 aren't yet integrated.
5969 * tc-i860.[hc]: blew off the dust. Something must still be done
5970 about conflicting relocation types.
5972 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5975 * tc-i960.c, tc-sparc.c: white space and comments only.
5977 * tc-a29k.h: delete duplicate macro definition.
5979 * new file atof-ns32k.c copied from hack's last unreleased gas.
5981 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5983 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5986 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5987 ChangeLog's prior to this are sketchy at best. I have logs.
5988 They just aren't ChangeLogs.
