DESCRIPTION
full 64-bit product into rdest. The operands are considered unsigned integers. No overflow or underflow detection is
performed.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.
EXAMPLES
r60 = 0x100
r10 = 0, r60 = 0x100, r30 = 0xf11
r20 = 1, r60 = 0x100, r30 = 0xf11
r70 = 0x100, r40 = 0xffffff9c
