/*
   After deciding the instruction entry (via hash.c) the instruction parser
   will try to match the operands after the instruction to the required set
   given in the entry operandfield. Every operand will result in a change in
   the opcode or the addition of data to the opcode.
   The operands in the source instruction are checked for inconsistent
   semantics.

	F : 32 bit float	general form
	L : 64 bit float	    "
	B : byte		    "
	W : word		    "
	D : double-word		    "
	A : double-word		gen-address-form ie no regs, no immediate
	I : integer writeable   gen int except immediate (A + reg)
	Z : floating writeable	gen float except immediate (Z + freg)
	d : displacement
	b : displacement - pc relative addressing  acb
	p : displacement - pc relative addressing  br bcond bsr cxp
	q : quick
	i : immediate (8 bits)
	    This is not a standard ns32k operandtype, it is used to build
	    instructions like    svc arg1,arg2
	    Svc is the instruction SuperVisorCall and is sometimes used to
	    call OS-routines from usermode. Some args might be handy!
	r : register number (3 bits)
	O : setcfg instruction optionslist
	C : cinv instruction optionslist
	S : stringinstruction optionslist
	U : registerlist	save,enter
	u : registerlist	restore,exit
	M : mmu register
	P : cpu register
	g : 3:rd operand of inss or exts instruction
	G : 4:th operand of inss or exts instruction
	    Those operands are encoded in the same byte.
	    This byte is placed last in the instruction.
	f : operand of sfsr
	H : sequent-hack for bsr (Warning)

column	1 	instructions
	2 	number of bits in opcode.
	3 	number of bits in opcode explicitly
		determined by the instruction type.
	4 	opcodeseed, the number we build our opcode
		from.
	5 	operandtypes, used by operandparser.
	6 	size in bytes of immediate

   addressing extension for operand A
   addressing extension for operand B
   implied operands

   Operand A is the operand listed first in the following opcode table.
   Operand B is the operand listed second in the following opcode table.
   All instructions have at most 2 general operands, so this is enough.
   The implied operands are associated with operands other than A and B.

   Each operand has a digit and a letter.

   The digit gives the position in the assembly language.  The letter,
   one of the following, tells us what kind of operand it is.  */
