LNO: Vector Intrinsics

• Most intrinsics have their “vector” equivalents. The compiler will automatically substitute vector intrinsics where legal, when the functions are invoked in a loop:

• Vector intrinsics are faster if Nᡂ for most intrinsics

  • Vector intrinsics have different precision rules (1 or 2 ulp less)
  • illegal arguments cannot be trapped with the vector intrinsics
  • -LNO:vintr=off to disable the generation of the vector intrinsics
