/* operands are indicated with a letter combination:
	b -	general operand of byte size
	w -	general operand of word size
	l -	general operand of long size
	u -	general operand of > long size (immediate mode is not
		implemented for this size, and neither are immediate
		floating point encodings
	A -	an operand of which the address is taken (so, no register
		or immediate mode)
	V -	a bit-field operand (no immediate mode)
	Bb -	byte offset branch
	Bw -	word offset branch
	Bl -	long offset branch
	Bx -	branch, size of offset determined by instruction
	Be -	extended conditional branch; the instruction may be replaced
		by a reverse-conditional branch over a branch or jump
