480 (EMIT_SECTION_SYMBOLS): Default to 1.

1924 * config/tc-m68k.h: Don't define REGISTER_PREFIX or
1925 OPTIONAL_REGISTER_PREFIX if either is already defined.
1927 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
1929 * configure.in: Set bfd_gas for all sparc targets. Added facility
1930 for keeping or rejecting configurations still under development;
1931 default is to assume production environment, and reject configs
1932 still being worked on. Mark Elf configurations (except sparc and
1933 i386) as developmental. Deleted cases matching some generic names
1934 in favor of more specific names. (E.g., when we get Alpha
1935 support, we'll still only support VMS for Vax.)
1937 * config/tc-sparc.h (md_end): New macro.
1938 * config/tc-sparc.c (md_end): Function deleted.
1939 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

1949 against placing additional object-file dependent code here. Warn
1950 against contaminating all of GAS with the internals of tc-hppa.c
1951 through inclusion of tc-hppa.h. Delete all forward declarations
1952 for functions only used within tc-hppa.c, likewise for structures,
1953 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1954 conditional code in a few small places.
1956 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1957 structures, global variables, forward declarations together.
1958 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
1959 conditional code -- try to group conditional code together
1960 into a few places. Make all functions and variables which
1961 are only used within tc-hppa.c static. PARAMize all functions.
1962 Add comments to functions. Delete unused functions, variables,
1963 #defines, etc. Delete unused members within structures. Delete
1964 ldil;ble hacks -- it is believed they were installed to work
1965 around old gas bugs. Avoid using mixed case for local
1966 functions, variables, and structures. Fix formatting problems
1967 not found by GNU-indent. Add FIXME notices for things which
1968 should be worked on the near future. Delete lots of old
1969 useless (1.36 PA-SOM) code.

1981 which do not involve function symbols.
1983 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
1984 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
1986 * config/tc-hppa.c: Likewise.
1988 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
1989 of elf32_symbol_type.
1990 (pa_export_args): Likewise.
1991 (elf_hppa_final_processing): Likewise.
1992 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed
1994 (hppa_tc_make_sections): Do not declare elf_get_symtab_map any
1997 * config/tc-hppa.c: (md_section_align): Align all sections to
1998 a multiple of the section alignment rather than always a
2001 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
2002 bits are zero (eg they specify no relocations), then do not even
2003 bother adding their entries to thesymextn section.

2040 instead add a second loop over special_chars. Set alignment
2041 of text, data and bss sections to 4.
2042 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2044 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2045 ELF, since the ELF object format does not have these type of
2046 relocations. Change the abort into as as_bad and return
2047 BFD_RELOC_NONE to silence compiler warnings.
2048 (md_assemble): Keep track of the instruction size. Allow white
2049 space between the $ and the constant for compatibility with older
2050 gases and other assemblers.
2051 (i386_operand): Skip spaces between $ and expression.

4411 source directory, if that's not the current directory.
4413 * configure.in (per-host): Accept MIPS host with BSD version

4435 process relocs if there aren't any relocs to process. Avoids
4436 malloc/free bug on SCO too.

4439 avoid some redefinition complaints on some systems.
4440 (const, volatile): Don't need these conditionally defined if we
4441 use CONST and VOLATILE from ansidecl.h.
4442 (seg_name): Use CONST, not const.
4444 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4446 * config/tc-mips.c: Reindented to GNU standards.

4450 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4451 (fixup_segment): Add a29k special case; the linker is not prepared
4452 to see a segment offset here.
4454 * app.c (do_scrub_next_char): Added new state, 10, modifying state

4457 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4459 * Makefile.in: add dvi target; as-$(config).texinfo might live in
4460 srcdir, might be in objdir.

4475 bignums, but don't emit error message.
4477 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
4479 * Makefile.in (targ-cpu.o): Depend on config.h.
4481 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4483 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4484 dropping a space immediately following an identifier.
4485 * expr.c, write.c: Rewrote assert expressions to not use multiple
4486 lines; I don't think that can be done portably.
4487 * config/tc-mips.c (macro): Use $AT if target register is zero in
4488 load instruction, which it can be for a floating point load.
4490 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4504 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
4507 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

4511 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4513 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4514 to be on a single line.

4561 * config/tc-mips.c: Rearranged for ECOFF support. Added
4562 prototypes for all static functions. Moved existing minimal
4563 debugging format support info #ifndef OBJ_ECOFF blocks.

4612 * make-gas.com: Find obstack.obj if it's not in the current
4614 * read.c (s_ignore): Don't declare is_end_of_line. It's
4615 redundant, and triggers a VMS gcc compiler bug.
4617 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4618 current segment as an argument. (Ignored in all cases but VMS.)
4619 All callers and definitions changed.

4637 argument to s_ignore. Put "#if 0" around unused code.
4638 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
4639 Call elf_xstabs for .stabs and .xstabs operators.

4916 md_relax_table): Use default zero initialization.
4917 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4918 latter, instead of selecting with preprocessor conditionals.
4920 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4922 * configure.in: recognise all sparclite variants

4932 * expr.c (operand): If character other than comma or newline is a
4933 logical end-of-line character, use the newline case.
4934 From Eric Youngdale:
4935 (operand): Set X_add_number field for floating-point numbers.
4936 (operand): Treat zero byte as end-of-operand.
4938 * configure.in (per-target): Look for with_bfd_assembler option.
4939 For now, only accept "no", until the merge is done.
4941 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4942 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
4943 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
4944 * read.c: Finish conversion to S_* macros in the VMS only
4945 parts of the program. Add "const" modifier to hex_value.
4946 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
4948 * expr.c: Add "const" modifier to hex_value.
4949 * symbols.c: Finish conversion to S_* macros in the VMS only
4950 parts of the program. Add "const" modifier to
4951 md_[long,short]_jump_size. Remove declaration of const_flag
4952 (which will be declared in obj-vms.h).
4953 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4954 Fix arguments to VMS_write_object_file.
4955 * config-gas.com: New file. Script for VMS systems to set up the
4956 configuration to build gas for VMS, and create config.status.
4957 * make-gas.com: Redone to work with new scheme.
4958 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4960 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4961 will swap bytes if needed on a big endian system. Use throughout
4963 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4964 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4965 types of malformed stabs. Change parsing algorithm so that we are
4966 more certain of having all of the information that we need on hand.
4967 * obj-vms.c (final_forward_reference): New function, used to help
4968 resolve the data types of as many struct elements as possible
4969 when some part of the struct is not fully defined by the compiler.

4972 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4973 as symbols as well in the object file. Look for external functions
4974 that start with "__vt.", and turn them into variables, since the
4975 g++ compiler is incapable of doing this.
4976 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4978 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4979 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4980 have the name of the source file yet.
4981 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4983 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4985 * read.c (s_data): Always use "data_section", since it'll map to
4986 SEG_DATA or SEG_E1 if needed.
4987 (s_lcomm): Likewise with bss_section.
4988 (s_fill): Use memset, not bzero.
4990 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5012 (big_section, reg_section, pass1_section, diff_section,
5013 absent_section, text_section, data_section, bss_section): If
5014 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5015 mapping to segT enum values.
5016 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5017 if these are used or defined, if BFD_ASSEMBLER.
5018 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5019 subseg_new split into two functions.
5020 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5022 * as.h (volatile): Don't define if already defined.
5023 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5025 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5026 declare with format attribute for -Wformat checking.
5028 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5030 * app.c, config/tc-*.c: Don't include read.h, since it is already
5033 * These are based on patches from Minh Tran-le
5034 <mtranle@paris.intellicorp.com>.
5035 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5036 obj_format coffbfd and gas_target i386coff for target.
5037 (i[34]86-*-isc*): New host (uses sysv).
5038 * config/i386aix.mt: Removed (no longer used).
5039 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5041 (LDFLAGS): Added, defined as -shlib.
5042 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5043 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5044 (DOT_LABEL_PREFIX): Define.
5045 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5046 name rather than L0\001.
5047 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5049 * symbols.c, symbols.h (local_bss_counter): Removed.

5058 (size_section): Restored sanity check.
5059 (do_relocs_for): Base section address on s_paddr rather than
5060 computing it. Adjust a29k R_IHIHALF special case to account for
5061 section paddr (used to require paddr to be zero). If there are no
5062 reclos, set s_relptr to 0. Set relocation size in object_headers.
5063 (fill_section): Always set s_vaddr here, removing
5064 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5065 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5066 Set STYP_INFO for .comment.
5067 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5068 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5070 H_{SET,GET}_* macros.
5071 (do_linenos_for): Set lineno size in object_headers.
5072 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5073 set s_vaddr here. If string_byte_count remains 4, set it back to
5074 0, and only write strings out if there are some. Call
5075 fill_section before do_relocs_for and do_linenos_for.
5076 (obj_coff_section): Handle optional quoted second argument giving
5077 section characteristics.
5078 (obj_coff_bss): Added to handle .bss.
5079 (obj_coff_ident): Added to handle .ident (puts string in .comment

5099 (do_scrub_next_char): For \", return " not '.
5100 (symbol_chars): Now const.
5102 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5103 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5105 * config/obj-coff.h: Don't use #elif.
5107 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5108 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5110 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5112 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5126 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
5128 * listing.c: Call xmalloc, not malloc; don't declare malloc.
5130 * Changes to support SCO 3.2v4:
5131 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
5132 SEG_BSS, fill with NOP_OPCODE.
5133 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
5134 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5135 using ZERO_BASED_SEGMENTS.
5136 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5137 never set segment address for SEG_E2 (.bss) and don't write out
5138 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5139 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5140 definitions, and don't merge tags with non-tags. Check for .bf
5141 rather than just checking whether the second character is b and
5142 the third character is f.
5143 (obj_coff_val): gcc can generate values which we don't handle
5144 correctly; discard information for now, since it only affects the
5145 debugging information.
5146 (tag_find_or_name): Don't insert tags in the symbol table.
5147 (yank_symbols): Don't merge labels.
5148 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5294 could be doing emulation.
5296 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5299 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5328 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5330 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5331 constant will not fit in an immediate field.
5332 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5367 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5369 * Support for i386-sysv.
5370 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5408 * tc-z8k.c: lots of bug fixes
5410 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5412 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5413 #elif, since it is not supported by old compilers.
5414 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5415 couple of expressions in tc-m68k.c.
5417 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5419 * read.c (cons): If NO_RELOC is defined, use it.
5421 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5423 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5425 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5426 local labels to start with a .) and set REGISTER_PREFIX to %.
5427 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5429 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5443 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5445 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5446 sections starting from zero, rather than making them consecutive.
5447 This makes subsequent reloc calculations easier, esp if the object
5448 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5449 allocate lcomm in .data rather than in .bss. It seems that some
5450 tools can't cope with a non-zero sized bss before linkage.
5452 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5454 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5473 * Makefile.in (install): if $(tooldir) exists, install as in
5476 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5478 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5479 .word is < -32768 or > 32767. The -J flag causes the error to be
5480 ignored. This is to catch over-sized switches generated by gcc on
5481 systems which don't support the broken .word hack.
5482 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5483 write.c (fixup_segment): check for signed .word overflow if
5484 WARN_SIGNED_OVERFLOW_WORD.
5486 * write.c (fixup_segment): fixed missing parens in expression
5487 checking for byte or word overflow.
5489 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

5503 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5505 * input-scrub.c (input_scrub_push): call input_file_begin, not
5507 messages.c (as_perror): print ": " between the passed in error and
5508 the strerror, like perror does.

5513 From Steve Chamberlain:
5514 Makefile.in: Handle m68*-*-coff*.
5515 read.c, read.h: add mult argument to s_space
5517 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5518 Motorola and MIT syntax; gas can now assemble either type of
5520 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5527 (fixup_segment) set fx_subsy to 0.
5528 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5530 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5533 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5535 * Makefile.in (LIBS): Include opcode library.
5537 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

5557 tc-i960.c (md_ri_to_chars): Always output bout object file in
5558 little endian byte order (used to use endianness of host).
5560 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5562 * config/tc-m68k.c (init_table): Now const. Always include 68851
5563 data, so that "bc" is available to 68040 cache instructions.
5564 Added "tt0", "tt1", and 68ec030 variants.
5565 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5566 (enum _register): Added TT0, TT1.
5567 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5568 line number correctly in "internal error" messages. Don't print
5569 architecture-mismatch message for operand errors.
5571 From Colin Smith (colin@wrs.com):
5572 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5573 than install_operand.
5575 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5577 * listing.c (buffer_line): rewind to the start of include
5578 files, they might be included twice.
5580 * z8k.c, z8k.h, z8k.mt: z8000 support stuff

5585 one element of a family.
5587 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
5589 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5590 so that we can assemble hand-written libgcc code.
5592 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5594 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5595 has already been formatted (but may still contain %-characters).
5598 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5600 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5601 written with indirection on the last two operands, which can be
5602 either data or address registers. Added a new operand type 'r'
5603 which accepts either register type. Added '(' to notend stuff in
5604 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
5606 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
5608 * as.h (enum _relax_state): Start off at one, not zero, to better

5617 data_last_frag): No longer static.
5618 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
5619 defined, call it. Change segments before calling fixup_segment.
5620 (relax_align): If linkrelax, provide extra padding.
5622 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
5623 their not having symbols associated.
5625 * tc-i960.c (norelax, instrument_branches): Default initializer is
5627 (linkrelax): Delete variable definition.
5628 (mem_fmt): Call fix_new with NO_RELOC.

5651 being used with args swapped, causing occasional lossage when
5652 refilling buffers after an include file.
5654 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
5656 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
5657 version. Discard bogus DONTDEF version.
5658 (as_warn, as_bad, as_fatal): Likewise.
5660 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
5662 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
5663 selected architecture, print a message saying so and listing what

5715 (md_assemble): If no CPU has been set (even if FPU/PMMU
5716 characteristics have been), default to 68020. Don't need extra
5717 quotes around error string.

5799 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
5801 * write.c (write_object_file): keep the fix_tail clean, which
5802 fixes a bug in -R where relocations were being lost.
5804 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5806 * configure.in: recognize m680x0 as having sun3 emulation mode for

5851 start addresses to match required alignment.
5853 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5855 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5856 where gcc looks for it.
5858 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5860 * Makefile.in: Changed some lines to be less confusing for some

5926 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5928 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5930 * expr.c (operand): if can't work out what sort of operand it is,
5931 then look through FLT_CHARS for a hint.
5933 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5935 * Makefile.in, configure.in: removed traces of namesubdir,
5936 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5937 copyrights to '92, changed some from Cygnus to FSF.
5939 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5940 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5941 copyrights to '92, changed some from Cygnus to FSF.
5943 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5945 * expr.c: If an expression is single comma, then return with
5946 SEG_ABSENT rather than an error - since the sparc front end does
5947 really strange things with things like fbge,a
5949 * as.h: include bfd.h if using many sections
5950 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5951 local labels didn't work.
5952 * listing.c (list_symbol_table): don't core dump when there's no
5954 * write.c, write.h: call fix_new with the right number of args on
5956 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5959 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5961 * app.c: MRI compatibility - allow single quote to start a string.
5962 * as.c: fix typo recently introduced.
5963 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5964 * expr.c: Much rewriting, to accomodate MRI syntax for
5965 expressions. Also easier to read now.
5966 * listing.c: Put back defuns
5967 * read.c: modified to accept MRI syntax, put back listing pseudo
5968 ops so that an assembler built with NO_LISTING ignores list ops
5970 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5971 machine is a SPARC or a 29K.
5972 * config/obj-aout.c: added s_sect pseudo op
5973 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5974 fill in the timestamp.
5975 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5976 anymore, define all the relocs which the tc-<x> bit will use so we
5977 can translate from them to the coff types.
5978 * config/tc-a29k.c: reloc_type isn't ane enum any more
5979 * config/tc-m68k.c: Added NO_RELOC definition.
5981 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5983 * Makefile.in: put header files before C source for TAGS; remove
5984 references to non-existent syscalls.h.
5986 * read.c, write.c subsegs.c: back out the .bss changes.
5988 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5990 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5994 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5996 * symbols.c (local_label_name): symbols now start with ^A.
5998 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5999 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6000 generate these sections. .align: will use NOP_OPCODE or 0
6001 for padding. This is just for being nice to the
6004 * expr.c (operand): changed to generate local label "\001L0"
6005 starting with a ^A so that it is recognized as a local label.
6007 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6009 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6010 i/o opcodes - inb, inw, outb and outw. string manipulation with
6011 att syntax - scmp, slod, smov, ssca, ssto.
6013 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6014 to just after .file .
6016 In obj_crawl_symbol_chain() where it tries to put the external
6017 symbols apart, with the condition:
6018 (!S_IS_DEFINED(symbolP) &&
6019 !S_IS_DEBUG(symbolP) &&
6020 !SF_GET_STATICS(symbolP))
6021 it was moving too many symbols out. So I switch it back to the
6023 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6025 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6026 so that we don't use the F_RELFLG which make the linker complain
6027 that somebody has stripped the relocation info.
6029 Also, the AIX ld program require that the relocation table
6030 is sorted by r_vaddr like the standard ATT assembler does.
6032 [he also changed the sizeof(struct ...)'s into the coff
6033 style FOOSZ macros. I'm not sure this is right, but I can't
6034 remember why. xoxorich.]
6036 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6038 * Makefile.in, configure.in, doc: use the doc. Build it, install
6041 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6043 * read.c: white space and comments only.
6045 * configure.in: use the new atof-ns32.c for ns32k.
6047 * write.c: comment change only.
6049 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6050 aren't yet integrated.
6052 * tc-i860.[hc]: blew off the dust. Something must still be done
6053 about conflicting relocation types.
6055 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6058 * tc-i960.c, tc-sparc.c: white space and comments only.
6060 * tc-a29k.h: delete duplicate macro definition.
6062 * new file atof-ns32k.c copied from hack's last unreleased gas.
6064 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6066 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6069 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6070 ChangeLog's prior to this are sketchy at best. I have logs.
6071 They just aren't ChangeLogs.
