;;; Test ‘llvm.pow.*’ intrinsic
;;;
;;; Syntax:
;;;   This is an overloaded intrinsic. You can use llvm.pow on any
;;;   floating-point or vector of floating-point type. Not all targets
;;;   support all types however.
;;;
;;; declare float     @llvm.pow.f32(float  %Val, float %Power)
;;; declare double    @llvm.pow.f64(double %Val, double %Power)
;;; declare x86_fp80  @llvm.pow.f80(x86_fp80  %Val, x86_fp80 %Power)
;;; declare fp128     @llvm.pow.f128(fp128 %Val, fp128 %Power)
;;; declare ppc_fp128 @llvm.pow.ppcf128(ppc_fp128  %Val, ppc_fp128 Power)
;;;
;;; Overview:
;;;   The ‘llvm.pow.*’ intrinsics return the first operand raised to
;;;   the specified (positive or negative) power.
;;;
;;; Arguments:
;;;   The arguments and return value are floating-point numbers of
;;;   the same type.
;;;
;;; Note:
;;;   We test only float/double/fp128.
