Functions ¶

func AddSetCarry ¶

func AddSetCarry(nl *gc.Node, nr *gc.Node, res *gc.Node)

AddSetCarry generates add and set carry.

res = nl + nr // with carry flag set

func BtoF ¶

func BtoF(b uint64) int

func BtoR ¶

func BtoR(b uint64) int

func Main ¶

func Main()

func RightShiftWithCarry ¶

func RightShiftWithCarry(n *gc.Node, shift uint, res *gc.Node)

RightShiftWithCarry generates a constant unsigned right shift with carry.

res = n >> shift // with carry

func RtoB ¶

func RtoB(r int) uint64

* track register variables including external registers: * bit reg * 0 R0 * 1 R1 * ... ... * 31 R31 * 32+0 F0 * 32+1 F1 * ... ... * 32+31 F31
