早期freebsd实现

Fri Jan  4 12:48:22 EST 1991	Jay Fenlason ([e-mail])

	* messages.c  Moved as_perror from input-scrub.c  Modified the
	error messages to look better.

	* output-file.c Don't call as_fatal, just call exit()

	expr.c Slightly improve checking for foo-foo case in
	clean_up_expression().  Detect foo: bar: ... foo-bar...

Tue Dec  4 16:29:20 EST 1990	Jay Fenlason ([e-mail])

	* m68k.c  Fixed an obscure bug involving AOFF mode with a
	large constant displacement (Was forgetting to output the
	extension word.)

	make-gas.com  Added a three line patch from Eric Youngdale that
	makes it possible to submit make-gas.com to a batch queue.

Wed Nov 21 15:07:51 EST 1990	Jay Fenlason ([e-mail])

	* vms.c  (VMS_TBT_Routine_END)  Add a four line patch from
	Eric Youngdale.

Tue Nov 13 14:02:15 EST 1990	Jay Fenlason ([e-mail])

	* vms-dbg.c (VMS_DBG_record())  Another one character patch from
	Eric Youngdale.

Mon Oct 29 15:49:21 EST 1990	Jay Fenlason ([e-mail])

	* read.c  Replace some as_warn calls with as_bad.

Fri Oct 26 15:21:15 EDT 1990	Jay Fenlason ([e-mail])

	* i386.c, i860.c, ns32k.c	Add const changes.

Mon Oct 22 14:04:26 EDT 1990	Jay Fenlason ([e-mail])

	* sparc.c	Add const changes.

	* make-gas.com	define const= for VMS, since many older versions of
	GCC don't work correctly with const under VMS.

Thu Oct 18 12:44:11 EDT 1990	Jay Fenlason ([e-mail])

	* i860.c i860-opcode.h  Added patches from [e-mail]

	* read.c, symbols.c, vms.c, + new_file vms-dbg-module.c
	Added Eric Youngdale's <[e-mail]> VMS debugging
	patches, so debugging GCC output now works.

	* hash.c (hash_grow)  Remember to blank out the wall entry in the new
	hash table.  This is important on systems where malloc() returns
	non-zero storage. . .

Tue Oct 16 10:11:35 EDT 1990	Jay Fenlason ([e-mail])

	* output-file.c (output_file_create)  if output filename is given as
	'-', write to stdout.

	* m68k.c Finally get the PCREL code to work right.  Add relaxation of
	PCREL stuff  This small fix from Ken Woodland
	([e-mail]).

	* m68k.c  Added some const declarations to constants.  (md_relax_table,
	md_pseudo_table, etc. . .)

Thu Oct 11 11:15:10 EDT 1990	Jay Fenlason ([e-mail])

	* Makefile, read.c, write.c Include the i860 port.
	(New files i860.c i860-opcode.h i860.h)

	* m68k.c Fix some addressing modes, (AOFF, AINDEX, etc) to work in
	PC relative mode.

	* (all over)  Raeburn's const hacking.  This reduces the data-space size by
	declaring many tables, etc, as 'const'.

Thu Sep 27 13:43:49 EDT 1990	Jay Fenlason ([e-mail])

	* m68k.c (get_num)  Fix so that 1:w is treated properly.

	* Makefile  Replace references to a.out.h with a.out.gnu.h

Tue Sep 25 15:50:36 EDT 1990	Jay Fenlason ([e-mail])

	that the locations in question do.  A xix line patch from Michael Bloom
	(usc!srhqla!quad1!psivax!ttidca![e-mail])

Mon Sep 24 11:43:15 EDT 1990	Jay Fenlason ([e-mail])

	* as.c  #include <sys/types.h> if _POSIX_SOURCE defined.  This because
	<signal.h> uses pid_t that's defined in it.

	* m68k.c reverse the sense of -l option, and allow :w and :l to
	override the default size of AOFF indexes.

	Also, allow -l to shorten branches to unknown labels from LONG to WORD.

Thu Sep 13 17:05:09 EDT 1990	Jay Fenlason ([e-mail])

	* read.c (pseudo_set) Compain if we're setting the symbol to the
	difference of two symbols which are in different frags.  (We can't
	find out how far apart they are.)

Wed Aug 15 12:18:58 EDT 1990	Jay Fenlason

	* m68k.c (m68k_ip_op)  Dyke out the code that deals with parsing
	:[wl] at the end of expressions since it is handled in get_num()
	and this was putting the result in the wrong place anyway.
	Corrected a couple of other references to ->isiz instead of con?->e_siz

Mon Aug 13 15:53:46 EDT 1990	Jay Fenlason

	* read.c  Handle .align specially on the sparc, or any other machine

Wed Aug  1 13:30:48 EDT 1990	Jay Fenlason ([e-mail])

	vax.c (md_assemble)  print a useful error message if expression()

	([e-mail]) for c++?  (A dozen lines or so)

Mon Nov 13 11:48:44 EST 1989	[e-mail]

	I hope this works!

	m68k.c (s_proc (new))  Added s_proc no-op pseudo-op.
