Argument type and attributes

ARG1

An INTENT(IN) VECTOR(UNSIGNED(1)) or VECTOR(SIGNED(1)).

Result type and attributes

The result is of the same type as ARG1.

Result value

Each doubleword element of the result is set as follows:

Let x(i) (0 <= i < 8) denote the byte elements of the corresponding input doubleword element, with x(7) as the most significant byte. For each pair of i and j (0 <= i < 8, 0 <= j < 8), the jth bit of the ith byte element of the result is set to the value of the ith bit of the jth byte element of the input.
