;;; Test ‘llvm.smax.*’ intrinsic
;;;
;;; Syntax:
;;;   This is an overloaded intrinsic. You can use @llvm.smax on any
;;;   integer bit width or any vector of integer elements.
;;;
;;; declare i32 @llvm.smax.i32(i32 %a, i32 %b)
;;; declare <4 x i32> @llvm.smax.v4i32(<4 x i32> %a, <4 x i32> %b)
;;;
;;; Overview:
;;;   Return the larger of %a and %b comparing the values as signed
;;;   integers. Vector intrinsics operate on a per-element basis.
;;;   The larger element of %a and %b at a given index is returned
;;;   for that index.
;;;
;;; Arguments:
;;;   The arguments (%a and %b) may be of any integer type or a vector
;;;   with integer element type. The argument types must match each
;;;   other, and the return type must match the argument type.
;;;
;;; Note:
;;;   We test only i8/i16/i32/i64/i128.
