Multivector floatingpoint adjust exponent
Multiply the floatingpoint elements of the two or four first source vectors by 2.0 to the power of the signed integer values in the corresponding elements of the two or four second source vectors and destructively place the results in the corresponding elements of the two or four first source vectors.
This instruction follows SME2 floatingpoint numerical behaviors corresponding to instructions that place their results in one or more SVE Z vectors.
This instruction is unpredicated.
It has encodings from 2 classes: Two registers and Four registers
