486 (EMIT_SECTION_SYMBOLS): Default to 1.

1930 * config/tc-m68k.h: Don't define REGISTER_PREFIX or
1931 OPTIONAL_REGISTER_PREFIX if either is already defined.
1933 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
1935 * configure.in: Set bfd_gas for all sparc targets. Added facility
1936 for keeping or rejecting configurations still under development;
1937 default is to assume production environment, and reject configs
1938 still being worked on. Mark Elf configurations (except sparc and
1939 i386) as developmental. Deleted cases matching some generic names
1940 in favor of more specific names. (E.g., when we get Alpha
1941 support, we'll still only support VMS for Vax.)

1955 against placing additional object-file dependent code here. Warn
1956 against contaminating all of GAS with the internals of tc-hppa.c
1957 through inclusion of tc-hppa.h. Delete all forward declarations
1958 for functions only used within tc-hppa.c, likewise for structures,
1959 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1960 conditional code in a few small places.
1962 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1963 structures, global variables, forward declarations together.
1964 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
1965 conditional code -- try to group conditional code together
1966 into a few places. Make all functions and variables which
1967 are only used within tc-hppa.c static. PARAMize all functions.
1968 Add comments to functions. Delete unused functions, variables,
1969 #defines, etc. Delete unused members within structures. Delete
1970 ldil;ble hacks -- it is believed they were installed to work
1971 around old gas bugs. Avoid using mixed case for local
1972 functions, variables, and structures. Fix formatting problems
1973 not found by GNU-indent. Add FIXME notices for things which
1974 should be worked on the near future. Delete lots of old
1975 useless (1.36 PA-SOM) code.

1987 which do not involve function symbols.
1989 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
1990 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
1992 * config/tc-hppa.c: Likewise.
1994 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
1995 of elf32_symbol_type.
1996 (pa_export_args): Likewise.
1997 (elf_hppa_final_processing): Likewise.
1998 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

2003 * config/tc-hppa.c: (md_section_align): Align all sections to
2004 a multiple of the section alignment rather than always a
2007 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
2008 bits are zero (eg they specify no relocations), then do not even
2009 bother adding their entries to thesymextn section.

2048 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2050 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2051 ELF, since the ELF object format does not have these type of
2052 relocations. Change the abort into as as_bad and return
2053 BFD_RELOC_NONE to silence compiler warnings.
2054 (md_assemble): Keep track of the instruction size. Allow white
2055 space between the $ and the constant for compatibility with older
2056 gases and other assemblers.

4331 than ECOFF line number information.
4332 (obj_ecoff_stab): Accept non-zero values for stabs line number.

4334 to small, undefined and/or readonly sections if appropriate.
4335 Don't output symbol names containing \001 characters.
4336 (ecoff_frob_file): Make sure at least one fdr is output.

4393 dependencies are read, not when they are used).
4395 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
4396 a29k .bss section; the mondfe program doesn't like it.

4417 source directory, if that's not the current directory.
4419 * configure.in (per-host): Accept MIPS host with BSD version

4441 process relocs if there aren't any relocs to process. Avoids
4442 malloc/free bug on SCO too.

4445 avoid some redefinition complaints on some systems.
4446 (const, volatile): Don't need these conditionally defined if we
4447 use CONST and VOLATILE from ansidecl.h.
4448 (seg_name): Use CONST, not const.
4450 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4452 * config/tc-mips.c: Reindented to GNU standards.

4456 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4457 (fixup_segment): Add a29k special case; the linker is not prepared
4458 to see a segment offset here.
4460 * app.c (do_scrub_next_char): Added new state, 10, modifying state
4461 9 to only keep a space in between identifier characters.
4463 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4465 * Makefile.in: add dvi target; as-$(config).texinfo might live in
4466 srcdir, might be in objdir.
4468 * doc/Makefile.in: dvi depends on as.dvi

4481 bignums, but don't emit error message.
4483 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
4485 * Makefile.in (targ-cpu.o): Depend on config.h.
4487 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4489 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4490 dropping a space immediately following an identifier.
4491 * expr.c, write.c: Rewrote assert expressions to not use multiple
4492 lines; I don't think that can be done portably.
4493 * config/tc-mips.c (macro): Use $AT if target register is zero in
4494 load instruction, which it can be for a floating point load.
4496 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)
4498 * write.c (write_contents): Compute the relocs before writing out

4510 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
4513 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

4517 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4519 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4520 to be on a single line.
4522 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

4567 * config/tc-mips.c: Rearranged for ECOFF support. Added
4568 prototypes for all static functions. Moved existing minimal
4569 debugging format support info #ifndef OBJ_ECOFF blocks.

4618 * make-gas.com: Find obstack.obj if it's not in the current
4620 * read.c (s_ignore): Don't declare is_end_of_line. It's
4621 redundant, and triggers a VMS gcc compiler bug.
4623 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4624 current segment as an argument. (Ignored in all cases but VMS.)
4625 All callers and definitions changed.

4643 argument to s_ignore. Put "#if 0" around unused code.
4644 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
4645 Call elf_xstabs for .stabs and .xstabs operators.

4922 md_relax_table): Use default zero initialization.
4923 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4924 latter, instead of selecting with preprocessor conditionals.
4926 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4928 * configure.in: recognise all sparclite variants
4930 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

4938 * expr.c (operand): If character other than comma or newline is a
4939 logical end-of-line character, use the newline case.
4940 From Eric Youngdale:
4941 (operand): Set X_add_number field for floating-point numbers.
4942 (operand): Treat zero byte as end-of-operand.
4944 * configure.in (per-target): Look for with_bfd_assembler option.
4945 For now, only accept "no", until the merge is done.
4947 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4948 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4950 * read.c: Finish conversion to S_* macros in the VMS only
4951 parts of the program. Add "const" modifier to hex_value.
4952 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
4954 * expr.c: Add "const" modifier to hex_value.
4955 * symbols.c: Finish conversion to S_* macros in the VMS only
4956 parts of the program. Add "const" modifier to
4957 md_[long,short]_jump_size. Remove declaration of const_flag
4958 (which will be declared in obj-vms.h).
4959 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4960 Fix arguments to VMS_write_object_file.
4961 * config-gas.com: New file. Script for VMS systems to set up the
4962 configuration to build gas for VMS, and create config.status.
4963 * make-gas.com: Redone to work with new scheme.
4964 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4966 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4967 will swap bytes if needed on a big endian system. Use throughout
4969 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4970 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4971 types of malformed stabs. Change parsing algorithm so that we are
4972 more certain of having all of the information that we need on hand.
4973 * obj-vms.c (final_forward_reference): New function, used to help
4974 resolve the data types of as many struct elements as possible
4975 when some part of the struct is not fully defined by the compiler.

4978 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4979 as symbols as well in the object file. Look for external functions
4980 that start with "__vt.", and turn them into variables, since the
4981 g++ compiler is incapable of doing this.
4982 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4984 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4985 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4986 have the name of the source file yet.
4987 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4989 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4991 * read.c (s_data): Always use "data_section", since it'll map to
4992 SEG_DATA or SEG_E1 if needed.
4993 (s_lcomm): Likewise with bss_section.
4994 (s_fill): Use memset, not bzero.
4996 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5017 (section_alignment): Declare only if not BFD_ASSEMBLER.
5018 (big_section, reg_section, pass1_section, diff_section,
5019 absent_section, text_section, data_section, bss_section): If
5020 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5021 mapping to segT enum values.
5022 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5023 if these are used or defined, if BFD_ASSEMBLER.
5024 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5025 subseg_new split into two functions.
5026 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5028 * as.h (volatile): Don't define if already defined.
5029 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5031 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5032 declare with format attribute for -Wformat checking.
5034 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5036 * app.c, config/tc-*.c: Don't include read.h, since it is already
5039 * These are based on patches from Minh Tran-le
5040 <mtranle@paris.intellicorp.com>.
5041 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5042 obj_format coffbfd and gas_target i386coff for target.
5043 (i[34]86-*-isc*): New host (uses sysv).
5044 * config/i386aix.mt: Removed (no longer used).
5045 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5047 (LDFLAGS): Added, defined as -shlib.
5048 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5049 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5050 (DOT_LABEL_PREFIX): Define.
5051 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5052 name rather than L0\001.
5053 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5055 * symbols.c, symbols.h (local_bss_counter): Removed.
5056 * write.c (write_object_file): bss no longer uses

5064 (size_section): Restored sanity check.
5065 (do_relocs_for): Base section address on s_paddr rather than
5066 computing it. Adjust a29k R_IHIHALF special case to account for
5067 section paddr (used to require paddr to be zero). If there are no
5068 reclos, set s_relptr to 0. Set relocation size in object_headers.
5069 (fill_section): Always set s_vaddr here, removing
5070 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5071 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5072 Set STYP_INFO for .comment.
5073 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5074 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5076 H_{SET,GET}_* macros.
5077 (do_linenos_for): Set lineno size in object_headers.
5078 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5079 set s_vaddr here. If string_byte_count remains 4, set it back to
5080 0, and only write strings out if there are some. Call
5081 fill_section before do_relocs_for and do_linenos_for.
5082 (obj_coff_section): Handle optional quoted second argument giving
5083 section characteristics.
5084 (obj_coff_bss): Added to handle .bss.
5085 (obj_coff_ident): Added to handle .ident (puts string in .comment

5105 (do_scrub_next_char): For \", return " not '.
5106 (symbol_chars): Now const.
5108 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5109 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5111 * config/obj-coff.h: Don't use #elif.
5113 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5114 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5116 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5118 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5132 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
5134 * listing.c: Call xmalloc, not malloc; don't declare malloc.
5136 * Changes to support SCO 3.2v4:
5137 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
5138 SEG_BSS, fill with NOP_OPCODE.
5139 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
5140 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5141 using ZERO_BASED_SEGMENTS.
5142 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5143 never set segment address for SEG_E2 (.bss) and don't write out
5144 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5145 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5146 definitions, and don't merge tags with non-tags. Check for .bf
5147 rather than just checking whether the second character is b and
5148 the third character is f.
5149 (obj_coff_val): gcc can generate values which we don't handle
5150 correctly; discard information for now, since it only affects the
5151 debugging information.
5152 (tag_find_or_name): Don't insert tags in the symbol table.
5153 (yank_symbols): Don't merge labels.
5154 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5157 (obj_coff_section): Accept and ignore a trailing quoted string, as
5158 used in AT&T i386 syntax.
5159 (fixup_segment): Take segment as argument. On the i386, adjust PC
5160 relative addends by the segment vaddr.
5161 * tc-i386.h: Define SUB_SEGMENT_ALIGN.

5300 could be doing emulation.
5302 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5305 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5334 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5336 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5337 constant will not fit in an immediate field.
5338 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5373 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5375 * Support for i386-sysv.
5376 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5414 * tc-z8k.c: lots of bug fixes
5416 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5418 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5419 #elif, since it is not supported by old compilers.
5420 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5421 couple of expressions in tc-m68k.c.
5423 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5425 * read.c (cons): If NO_RELOC is defined, use it.
5427 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5429 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5431 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5432 local labels to start with a .) and set REGISTER_PREFIX to %.
5433 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5435 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5449 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5451 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5452 sections starting from zero, rather than making them consecutive.
5453 This makes subsequent reloc calculations easier, esp if the object
5454 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5455 allocate lcomm in .data rather than in .bss. It seems that some
5456 tools can't cope with a non-zero sized bss before linkage.
5458 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5460 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5479 * Makefile.in (install): if $(tooldir) exists, install as in
5482 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5484 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5485 .word is < -32768 or > 32767. The -J flag causes the error to be
5486 ignored. This is to catch over-sized switches generated by gcc on
5487 systems which don't support the broken .word hack.
5488 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5489 write.c (fixup_segment): check for signed .word overflow if
5490 WARN_SIGNED_OVERFLOW_WORD.
5492 * write.c (fixup_segment): fixed missing parens in expression
5493 checking for byte or word overflow.
5495 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

5509 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5511 * input-scrub.c (input_scrub_push): call input_file_begin, not
5513 messages.c (as_perror): print ": " between the passed in error and
5514 the strerror, like perror does.

5519 From Steve Chamberlain:
5520 Makefile.in: Handle m68*-*-coff*.
5521 read.c, read.h: add mult argument to s_space
5523 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5524 Motorola and MIT syntax; gas can now assemble either type of
5526 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5533 (fixup_segment) set fx_subsy to 0.
5534 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5536 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5539 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5541 * Makefile.in (LIBS): Include opcode library.
5543 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

5563 tc-i960.c (md_ri_to_chars): Always output bout object file in
5564 little endian byte order (used to use endianness of host).
5566 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5568 * config/tc-m68k.c (init_table): Now const. Always include 68851
5569 data, so that "bc" is available to 68040 cache instructions.
5570 Added "tt0", "tt1", and 68ec030 variants.
5571 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5572 (enum _register): Added TT0, TT1.
5573 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5574 line number correctly in "internal error" messages. Don't print
5575 architecture-mismatch message for operand errors.
5577 From Colin Smith (colin@wrs.com):
5578 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5579 than install_operand.
5581 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5583 * listing.c (buffer_line): rewind to the start of include
5584 files, they might be included twice.
5586 * z8k.c, z8k.h, z8k.mt: z8000 support stuff

5593 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
5595 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5596 so that we can assemble hand-written libgcc code.
5598 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5600 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5601 has already been formatted (but may still contain %-characters).
5604 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5606 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5607 written with indirection on the last two operands, which can be
5608 either data or address registers. Added a new operand type 'r'
5609 which accepts either register type. Added '(' to notend stuff in
5610 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
5612 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
5614 * as.h (enum _relax_state): Start off at one, not zero, to better

5623 data_last_frag): No longer static.
5624 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
5625 defined, call it. Change segments before calling fixup_segment.
5626 (relax_align): If linkrelax, provide extra padding.
5628 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
5629 their not having symbols associated.
5631 * tc-i960.c (norelax, instrument_branches): Default initializer is
5633 (linkrelax): Delete variable definition.
5634 (mem_fmt): Call fix_new with NO_RELOC.

5657 being used with args swapped, causing occasional lossage when
5658 refilling buffers after an include file.
5660 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
5662 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
5663 version. Discard bogus DONTDEF version.
5664 (as_warn, as_bad, as_fatal): Likewise.
5666 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
5668 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the

5722 characteristics have been), default to 68020. Don't need extra
5723 quotes around error string.

5805 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
5807 * write.c (write_object_file): keep the fix_tail clean, which
5808 fixes a bug in -R where relocations were being lost.
5810 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5812 * configure.in: recognize m680x0 as having sun3 emulation mode for

5857 start addresses to match required alignment.
5859 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5861 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5862 where gcc looks for it.
5864 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5866 * Makefile.in: Changed some lines to be less confusing for some

5932 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5934 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5936 * expr.c (operand): if can't work out what sort of operand it is,
5937 then look through FLT_CHARS for a hint.
5939 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5941 * Makefile.in, configure.in: removed traces of namesubdir,
5942 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5943 copyrights to '92, changed some from Cygnus to FSF.
5945 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5946 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5947 copyrights to '92, changed some from Cygnus to FSF.
5949 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5951 * expr.c: If an expression is single comma, then return with
5952 SEG_ABSENT rather than an error - since the sparc front end does
5953 really strange things with things like fbge,a
5955 * as.h: include bfd.h if using many sections
5956 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5957 local labels didn't work.
5958 * listing.c (list_symbol_table): don't core dump when there's no
5960 * write.c, write.h: call fix_new with the right number of args on
5962 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5965 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5967 * app.c: MRI compatibility - allow single quote to start a string.
5968 * as.c: fix typo recently introduced.
5969 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5970 * expr.c: Much rewriting, to accomodate MRI syntax for
5971 expressions. Also easier to read now.
5972 * listing.c: Put back defuns
5973 * read.c: modified to accept MRI syntax, put back listing pseudo
5974 ops so that an assembler built with NO_LISTING ignores list ops
5976 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5977 machine is a SPARC or a 29K.
5978 * config/obj-aout.c: added s_sect pseudo op
5979 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5980 fill in the timestamp.
5981 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5982 anymore, define all the relocs which the tc-<x> bit will use so we
5983 can translate from them to the coff types.
5984 * config/tc-a29k.c: reloc_type isn't ane enum any more
5985 * config/tc-m68k.c: Added NO_RELOC definition.
5987 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5989 * Makefile.in: put header files before C source for TAGS; remove
5990 references to non-existent syscalls.h.
5992 * read.c, write.c subsegs.c: back out the .bss changes.
5994 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5996 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6000 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6002 * symbols.c (local_label_name): symbols now start with ^A.
6004 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6005 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6006 generate these sections. .align: will use NOP_OPCODE or 0
6007 for padding. This is just for being nice to the
6010 * expr.c (operand): changed to generate local label "\001L0"
6011 starting with a ^A so that it is recognized as a local label.
6013 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6015 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6016 i/o opcodes - inb, inw, outb and outw. string manipulation with
6017 att syntax - scmp, slod, smov, ssca, ssto.
6019 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6020 to just after .file .
6022 In obj_crawl_symbol_chain() where it tries to put the external
6023 symbols apart, with the condition:
6024 (!S_IS_DEFINED(symbolP) &&
6025 !S_IS_DEBUG(symbolP) &&
6026 !SF_GET_STATICS(symbolP))
6027 it was moving too many symbols out. So I switch it back to the
6029 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6031 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6032 so that we don't use the F_RELFLG which make the linker complain
6033 that somebody has stripped the relocation info.
6035 Also, the AIX ld program require that the relocation table
6036 is sorted by r_vaddr like the standard ATT assembler does.
6038 [he also changed the sizeof(struct ...)'s into the coff
6039 style FOOSZ macros. I'm not sure this is right, but I can't
6040 remember why. xoxorich.]
6042 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6044 * Makefile.in, configure.in, doc: use the doc. Build it, install
6047 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6049 * read.c: white space and comments only.
6051 * configure.in: use the new atof-ns32.c for ns32k.
6053 * write.c: comment change only.
6055 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6056 aren't yet integrated.
6058 * tc-i860.[hc]: blew off the dust. Something must still be done
6059 about conflicting relocation types.
6061 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6064 * tc-i960.c, tc-sparc.c: white space and comments only.
6066 * tc-a29k.h: delete duplicate macro definition.
6068 * new file atof-ns32k.c copied from hack's last unreleased gas.
6070 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6072 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6075 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6076 ChangeLog's prior to this are sketchy at best. I have logs.
6077 They just aren't ChangeLogs.
