DESCRIPTION
the opcode modifier, n; otherwise, rdest is set to 0. The arguments are treated as unsigned integers.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.

r30 = 3
r30 = 3
r30 = 3
r10 = 0, r40 = 0x100
r20 = 1, r40 = 0x100
r60 = 0x80000000
