Subject: missing instructions in the assembler 'as' (#65)
Index:	bin/as19.s,as29.s 2.11BSD

Description:
	While updating the debugger 'adb' it was noticed that the
	assembler was similarily deficient in some of the KDJ-11
	instructions.  These were added.

	Also the 'eae' instructions were removed, the odds of 2.11BSD
	ever running on a system which uses the EAE are not distinguishable
	from 0.

	The odd/unused/alternate spellings of some instructions were
	removed, e.g 'mpy' = 'mul', 'als' = 'ash', etc.  Not quite sure
	what the historical reasons were for these.  One of these days
	the assembler (and compilers) should be updated to use the 
	standard DEC mnemonics (and address mode notation): 'ldexp'
	instead of 'movei' and '@' instead of '*' for example.  _sigh_

Repeat-By:
	Examine the sources.

Fix:
	Apply the patch below (it updates two files, as19.s and as29.s).
	Remake the assembler.  Prior to installation (if you're in a
	paranoid mood) you might want to save /bin/as and /lib/as2
	(or just have the original distribution tapes around).  I simply
	installed the new assembler and it worked fine.
