The ARM asm implementation of InternalMathSwapBytes64 () does interesting things if bit 7 of operand r1 (upper 32 bits of the input value) is set. After the recursive swap, bit 7 ends up in the sign bit position, after which it is right shifted with sign extension, and or'ed with the upper half of the output value. This means SwapBytes64 (0x00000080_00000000) returns an incorrect value of 0xFFFFFFFF_80000000.
