FUNCTION
DESCRIPTION
rsrc2 and writes the most-significant 32 bits of the shifted result to rdest.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.
EXAMPLES
r30 = 0xaabbccdd, r40 = 0x11223344
r10 = 0, r40 = 0x11223344,
r30 = 0xaabbccdd
r20 = 1, r40 = 0x11223344,
r30 = 0xaabbccdd
