I am having troule with the gnu C compiler on an AViiON.  Specifically
I am running DG-UX (version 4.30) and with the optimiser on, the
compiler produces code that the assembler barfs on.  The function is
rather large and I would like to narrow it down before I ask for
detailed help.  But in the mean time I don't have any knowledge of nor
texts that describe the 88000 assembler.  Question is what does br.n
addr do?  Is it an unconditional branch or is it branch not equal to 0
or something else?  As usual help is greatly appreaciated!

FYI, from memory the code generated is something like

	br.n	addr1
	or	r1,r2,r3,0x1234
addrn	add	r10,r2,0x400

The assembler complains that or instructions cannot have 4 operands!
