SYNTAX
FUNCTION
DESCRIPTION
unsigned shift amount, and the two 16-bit integers shifted right by this amount. The sign bits rsrc1<31> and rsrc1<15>
are replicated as needed within each 16-bit value from the left. If the rsrc2<31:4> value is not zero, then take this as a
shift by 16 or more, i.e. extend the sign bit into either result.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.

The argument rsrc1 contains two 16-bit signed integers, rsrc1<31:16> and rsrc1<15:0>. Rsrc2 specifies an
