Mon Nov 23 11:50:00 1992  Ken Raeburn  (raeburn@cygnus.com)

	* obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.

	* tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
	could be doing emulation.

Tue Nov 10 09:50:25 1992  Ian Lance Taylor  (ian@cygnus.com)

	* tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
	still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
	the register name.
	(insert_reg): put REGISTER_PREFIX before register names before
	putting them in the symbol table.
	* tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not
	M68KCOFF.

	* obj-coffbfd.c (fill_section): set STYP_NOLOAD bit for .bss
	section.

	* atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
	comment_chars, line_comment_chars and line_seperator_chars
	consistently const, and always initialized them.  Included read.h.

Thu Nov  5 17:55:41 1992  Jim Wilson  (wilson@sphagnum.cygnus.com)

	* tc-sparc.c (sparc_ip): Add code to flag error if an absolute
	constant will not fit in an immediate field.
	(md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

Wed Nov  4 07:50:46 1992  Ken Raeburn  (raeburn@cygnus.com)

	* obj-coff.c (callj_table): Delete global variable.
	(obj_emit_relocations): Define it locally here, and only if
	TC_I960 is defined.

	* tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.
	(m68k_ip): Don't warn about bignum used as float bit-pattern.

	* obj-coff.c: Replaced ANSI and non-ANSI function declarations
	with a single set using PARAMS macro.

	* tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length
	of 2.

	* tc-i960.c: Missed a couple of 0->NO_RELOC conversions.

	* tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
	so widening works consistently.

Fri Oct 23 14:40:38 1992  Ian Lance Taylor  (ian@cygnus.com)

	* obj-coffbfd.c (write_object_file): check return value of
	bfd_close_all_done.

Tue Oct 20 13:02:25 1992  Ian Lance Taylor  (ian@cygnus.com)

	* Support for i386-sysv.
	obj-coffbfd.c (do_relocs_for, write_object_file): set segment
	addresses to reasonable sizes.  New define ZERO_BASED_SEGMENTS can
	be used to set them all to zero as was done before.
	(fill_section): segment addresses now set in write_object_file.
	(fill_section): Don't set STYP_NOLOAD for .bss section.
	(fixup_segment): 386 uses strange common symbol format.
	tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
	compatibility with SVR3.2 linker.

Mon Oct  5 09:28:57 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

	 fix i960+non-bfd coff bit rot. 
	* obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
	support for C source listings. (obj_coff_endef): look in the right
	part of the symbol for the symbol name

	* tc-m68k.c (get_num): make it work for all segments, not just the
	first three.

Tue Sep 29 12:22:52 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

	* obj-coffbfd.c (write_object_file): don't fixup for the z8k
	* tc-z8k.c: lots of bug fixes

Tue Sep 29 10:51:55 1992  Ian Lance Taylor  (ian@cygnus.com)

	* tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
	#elif, since it is not supported by old compilers.
	ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
	couple of expressions in tc-m68k.c.

Mon Sep 28 21:16:51 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)

	* tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.

Fri Sep 25 18:18:52 1992  Ian Lance Taylor  (ian@cygnus.com)

	* tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
	local labels to start with a .) and set REGISTER_PREFIX to %.
	tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

Tue Sep 22 13:02:07 1992  Sean Eric Fagan  (sef@cygnus.com)

	* obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
	sections starting from zero, rather than making them consecutive.
	This makes subsequent reloc calculations easier, esp if the object
	format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
	allocate lcomm in .data rather than in .bss.  It seems that some
	tools can't cope with a non-zero sized bss before linkage.
 
Tue Sep 22 15:10:51 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)

	* tc-m68k.c: Replace "enum m68k_architecture" with "int"
	throughout.  That enum no longer means what we thought it meant.

	* tc-m68k.c (md_assemble, md_parse_option): Handle new
	"-mno-688[58]1" options.

	* tc-m68k.c: Added CPU32 support.

Fri Sep 18 08:02:18 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

	* tc-m68k.c (m68k_ip): An(disp) is not pc relative.

Sun Sep 13 20:29:39 1992  Ian Lance Taylor  (ian@cygnus.com)

	* obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
	obj-coffbfd.c (fixup_segment): check for signed .word overflow if
	WARN_SIGNED_OVERFLOW_WORD.

	* obj-coffbfd.c (fixup_segment): fixed missing parens in
	expression checking for byte or word overflow.

Fri Sep 11 10:21:04 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

	Support for i386 coff
	* obj-coffbfd.h : added stuff 
	* tc-i386.c (tc_coff_fix2rtype): new function
	* tc-i386.h : new coff defines

Wed Sep  9 11:10:24 1992  Ian Lance Taylor  (ian@cygnus.com)

	* tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
	 Motorola and MIT syntax; gas can now assemble either type of
	 file.
	tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
	From Steve Chamberlain:
	m68kcoff.mt: for m68k COFF.
	obj-coffbfd.c: (fixup_mdeps) added
	 (size_section) removed bad sanity check
	 (fill_section) added rs_machine_dependent case
	 (write_object_file) call fixup_mdeps
	 (fixup_segment) set fx_subsy to 0.
	obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
	 handle m68k.
	tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
	 pseudo ops.

Fri Aug 28 16:25:22 1992  Ian Lance Taylor  (ian@cygnus.com)

	* obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
	tc-i960.c (md_ri_to_chars): Always output bout object file in
	little endian byte order (used to use endianness of host).

Tue Aug 25 15:11:08 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

	* z8k.c, z8k.h, z8k.mt: z8000 support stuff

Mon Aug 24 12:45:12 1992  Ian Lance Taylor  (ian@cygnus.com)

	* tc-m68k.c: use TARGET_CPU to choose default cpu type.

	* te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
	so that we can assemble hand-written libgcc code.

Wed Aug 19 11:20:59 1992  Ian Lance Taylor  (ian@cygnus.com)

	* tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
	written with indirection on the last two operands, which can be
	either data or address registers.  Added a new operand type 'r'
	which accepts either register type.  Added '(' to notend stuff in
	tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

Tue Aug 11 12:58:14 1992  Ken Raeburn  (raeburn@cygnus.com)

	* sparc.mt: New file.

Mon Aug 10 14:37:08 1992  Per Bothner  (bothner@cygnus.com)

	* tc-m68k.c: ".align N" means align to N-byte boundary *only*
	if TN_SUN3; otherwise align to 2**N-byte bounary.

Thu Aug  6 12:08:42 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

	* config/tc-h8300.c: if a :8 is seen after an operand, fill top
	two bytes of any constant with 0xff:

Wed Aug  5 01:54:34 1992  John Gilmore  (gnu at cygnus.com)

	* tc-m68k.c (try_index):  Error if index scaling specified and
	assembling for an older CPU than a 68020.

Mon Jul  6 17:09:32 1992  Steve Chamberlain  (sac@cygnus.com)

	* obj-coffbfd.c (fill_section): mark .lit sections as STYP_LIT

Tue Jun  9 07:50:46 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

	* tc-m68k.c (m68kip): Fix typo so that only arch's >=68020 do
	pcrel data stuff. (md_estimate_size_before_relax): when relaxing a
	68010 bxx into a bra+6 jmpxx, put the bytes of the jmp opcode into
	the right place. (s_bss): Don't put .bss stuff into SEG_DATA, put
	it into SEG_BSS

Thu May 28 11:20:27 1992  Jim Wilson  (wilson@sphagnum.cygnus.com)

	* tc-sparc.c: Use new ARCHITECTURES_CONFLICT_P macro.  Mention new
	-Asparclite flag.

Mon May  4 18:56:19 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

	* obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
	calc the base of relocs correctly.
	* tc-a29k.c (parse_operand): allow expressions to be in any section.

Thu Mar 12 04:42:38 1992  K. Richard Pixley  (rich@cygnus.com)

	* tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
	  tc-m68k.h to te-sun3.h. 

Wed Mar 11 23:34:46 1992  K. Richard Pixley  (rich@cygnus.com)

	* te-sun3.h: add LOCAL_LABELS_DOLLAR.

Fri Feb 21 06:22:15 1992  K. Richard Pixley  (rich@rtl.cygnus.com)

	* obj-aout.c: do not include stab.gnu.h if NO_LISTING.

	* tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.

	* a.out.h: removed.

Fri Feb 21 02:17:22 1992  Minh Tran-Le (TRANLE@INTELLICORP.COM)

	* tc-i386.c: tc-i386.c: added handling of the following opcodes:
	  i/o opcodes - inb, inw, outb and outw.  string manipulation with
	  att syntax - scmp, slod, smov, ssca, ssto.

Fri Feb 21 01:53:50 1992  Minh Tran-Le (TRANLE@INTELLICORP.COM)

	* obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
	  to just after .file .

	  In obj_crawl_symbol_chain() where it tries to put the external
	  symbols apart, with the condition:
	    (!S_IS_DEFINED(symbolP) &&
	     !S_IS_DEBUG(symbolP) &&
	     !SF_GET_STATICS(symbolP))
	  it was moving too many symbols out. So I switch it back to the
	  condition:
	    (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))

	  In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
	  so that we don't use the F_RELFLG which make the linker complain
	  that somebody has stripped the relocation info.

	  Also, the AIX ld program require that the relocation table
	  is sorted by r_vaddr like the standard ATT assembler does.

	  [he also changed the sizeof(struct ...)'s into the coff
	  style FOOSZ macros.  I'm not sure this is right, but I can't
	  remember why.  xoxorich.]

Tue Feb 18 02:11:10 1992  K. Richard Pixley  (rich at cygnus.com)

	* tc-m88k.[hc]: pulled in from hack's unfinished work.  These
	  aren't yet integrated.

	* tc-i860.[hc]: blew off the dust.  Something must still be done
	  about conflicting relocation types.

	* tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
	  real thing.

	* tc-i960.c, tc-sparc.c: white space and comments only.

	* tc-a29k.h: delete duplicate macro definition.

	* new file atof-ns32k.c copied from hack's last unreleased gas.
