; This test case aims to test the vector multiply instructions on Power10.
; This includes the low order and high order versions of vector multiply.
; The low order version operates on doublewords, whereas the high order version
; operates on signed and unsigned words and doublewords.
; This file also includes 128 bit vector multiply instructions.
