CMP<cc> (vectors) Compare vectors Compare active integer elements in the first source vector with corresponding elements in the second source vector, and place the boolean results of the specified comparison in the corresponding elements of the destination predicate. Inactive elements in the destination predicate register are set to zero. Sets the First (N), None (Z), !Last (C) condition flags based on the predicate result, and the V flag to zero. <cc> Comparison EQ equal GE signed greater than or equal GT signed greater than HI unsigned higher than HS unsigned higher than or same NE not equal Green True True This instruction is used by the aliases CMPLE (vectors) Never CMPLO (vectors) Never CMPLS (vectors) Never CMPLT (vectors) Never See below for details of when each alias is preferred.
