Based on the search mode specified in the syntax, the instruction tests for
maximum or minimum signed values.
Values are sign extended when copied into the Accumulator(s).
See "Example" for one way to implement the search loop. After the vector
search loop concludes,
dest_pointer_hi
The next step is to select the final value from these two surviving elements.
Modes
The four supported compare modes are specified by the mandatory
flag.
