Fri Sep  1 11:39:52 EDT 1989	hack@ai.mit.edu

	floating-point numbers.

Wed Aug 30 13:59:57 EDT 1989	hack@ai.mit.edu

	* Makefile  Remove the rest of the $< entries that kill sun make

Fri Aug 25 15:00:30 EDT 1989	Nobody You Know (hack@ai.mit.edu)

	* atof-m68k.c (gen_to_words) deal with denormalized floating-point
	numbers.

Tue Aug 22 02:03:05 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)

	* Makefile (gas-dist.tar): Put ChangeLog in the tar file.

	* version.c: Added comment telling Jay Fenl--I mean people--not to put
	changes in version.c, but to use ChangeLog instead.

	* version.c (version_string): Put "GNU" in all-caps.

	* version.c: Moved all comments about changes to ChangeLog (this file).
	Many anonymous entries have been attributed to Jay Fenlason (hack).

Thu Aug 17 15:53:57 1989  Jay Fenlason  (hack at apple-gunkies.ai.mit.edu)

	* Makefile: Removed $< references that seem
	to choke some versions of make.

	* frags.c (frag_grow): Fixed to deal with requests for very
	large frags (larger than frags.chunk_size).

	* app.c (do_scrub_next_char): Have it ignore any characters
	after the filename in a # line "filename".

	* sparc.c (s_common): On an error, don't print out
	input_line_pointer past the end of the line where the error is.

	* atof-generic.c (atof_generic): Accept any case for
	inf and nan.

	* m68k.c (m68_ip): Don't use PC-relative mode for alterable
	addressing modes.

Tue Aug 15 04:58:36 1989  Roland McGrath  (roland at apple-gunkies.ai.mit.edu)

	* sparc.c (md_begin): Rewrote this function to perform consistency
	checks with the new opcode table.

Fri Aug 11 16:01:16 1989  Roland McGrath  (roland at apple-gunkies.ai.mit.edu)

	* sparc-opcode.h (struct sparc_opcode): Replaced `mask' field with
	`lose'; removed `last' field.  Updated all opcodes accordingly.
	Fixed several opcodes that generated the wrong instructions.
	sparc.c (md_begin, sparc_ip): Changed to use new struct sparc_opcode.

Thu Aug  3 14:44:24 1989  Jay Fenlason  (hack at apple-gunkies.ai.mit.edu)

	* Makefile (a32k): Use read- and write-ns32k.o
	* ns32k.c (encode_operand): Make sure pcrel_adjust starts out zeroed.
	* read.c (cons): Call fix_new_ns32k() if NS32K is defined.
	* write.c (write_object_file): Ditto.
	These so that .word sym-sym (etc) will produce values with
	the proper byte-order.

Wed Aug 2 12:55:?? 1989  Jay Fenlason (hack at apple-gunkies.ai.mit.edu)

	* sparc.c (comment_chars[]): Removed '|' because it was causing
	problems.  Probably not the best fix, since I suspect other
	assemblers (68020) may get | in .stabs also, and the 68020 needs
	the '|' comment character.

Mon Jul 31 09:22:28 1989  Roland McGrath  (roland at apple-gunkies.ai.mit.edu)

	* sparc.c (sparc_ip): Allow the characters [0123] in opcodes.

	* atof-generic.c (atof_generic): Tried to keep
	size_of_digits_in_littlenum from going negative.

	* sparc-opcode.h: Added duplicate [i+1] entries to go with
	the [1+i] entries already there.  A kludgy fix, but it works.

Mon Jul 24 17:20:03 1989  Jay Fenlason  (hack)

	* write.c (relax_segment): Modified rs_org code so it won't
	occasionally dump core.

	* write.c (pseudo_set): Modified SEG_DIFFERENCE to (perhaps)
	allow one to set a symbol to the difference of two other symbols.

	* ns32k.c (convert_iif): Moved size_so_far+=size and size=0 inside
	 the check for a valid type.

	* sparc-opcode.h: Modified the entries for std "q,[1+i]", "D,[1+i]",
	and "Q,[1+i]".

	and inss instructions from 31 to 32 bits.

	* make-gas.com, version.c, hex-value.c, flonum-const.c: VMS fixes.

	* ns32k.c, ns32k-opcode.h: More fixes from taylor@think.com.

	  imull foo,%eax no longer gets assembled into the 32-64 bit
	  multiply, which clobbers %edx behind gcc's back

	  jcxz/jecxz were backwards

	  There was a bug when using %ebp as a base register with no
	  displacement

	  Instructions like andb $0xffffff, %al used to put out too many
	  immediate bytes

	  The splitting jump instructions across frags could happen when
	  obstack_room()==6 too.
