My compiler complains that "x always evaluates to true"

in this call:

	Result.IntVal = APInt(80, 2, x);

What is x?

	uint16_t x[8];

I deduce that the APInt constructor being used is this one:

  APInt(uint32_t numBits, uint64_t val, bool isSigned = false);

rather than this one:

  APInt(uint32_t numBits, uint32_t numWords, const uint64_t bigVal[]);

That doesn't seem right!  This fix compiles but is otherwise completely
untested.
