DESCRIPTION
arguments. (Note: pseudo operations cannot be used in assembly source files.)
and rdest is set to rsrc1 logically shifted left by this amount. If the rsrc2<31:5> value is not zero, then take this as a
shift by 32 or more bits. Zeros are shifted into the LSBs of rdest while the MSBs shifted out of rsrc1 are lost.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is unchanged.
