DESCRIPTION
rsrc2. The result is stored in the destination register, rdest.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.
EXAMPLES
r30 = 0xf310ffff, r40 = 0xffff0000
r10 = 0, r50 = 0x88888888
r20 = 1, r30 = 0xf310ffff,
r50 = 0x88888888
r60 = 0x11119999, r50 = 0x88888888
r70 = 0x55555555, r30 = 0xf310ffff
