func Add64

func Add64(x, y, carry uint64) (sum, carryOut uint64)

Add64 returns the sum with carry of x, y and carry: sum = x + y + carry. The carry input must be 0 or 1; otherwise the behavior is undefined. The carryOut output is guaranteed to be 0 or 1.

This function's execution time does not depend on the inputs. On supported platforms this is an intrinsic lowered by the compiler.

func MulUintptr

func MulUintptr(a, b uintptr) (uintptr, bool)

MulUintptr returns a * b and whether the multiplication overflowed. On supported platforms this is an intrinsic lowered by the compiler.
