Some other machines that have conditional assignment instructions:

1- The IBM TJWatson VLIW, developed by K.Ebcioglu. Its instructions
	are best represented as a tree such as

		if cc1 then
			R1=R2+R3
		else if cc2
`			R2=R3+R4
		else 
		        R3=R4+R5

   In other words, it allows for some form of ANDing of condition codes
to be specified on the (long) instruction.

2- The SIGNETICS LIFE processor: there, every opcode has a third (boolean)
	input. It also is a VLIW

3- The Multiflow TRACE has a "conditional assignment" opcode

	The references are
