// This algorithm uses 5 26-bit limbs to represent a 130-bit
// value. These limbs are, for the most part, zero extended and
// placed into 64-bit vector register elements. Each vector
// register is 128-bits wide and so holds 2 of these elements.
// Using 26-bit limbs allows us plenty of headroom to accommodate
// accumulations before and after multiplication without
// overflowing either 32-bits (before multiplication) or 64-bits

Register names:

	Rn is used for general purpose registers. (0-31)
	Fn is used for floating point registers. (0-31)
	Vn is used for vector registers. Slot 0 of Vn overlaps with Fn. (0-31)
	VSn is used for vector-scalar registers. V0-V31 overlap with VS32-VS63. (0-63)
	CTR represents the count register.
	LR represents the link register.
	CR represents the condition register
