;;; Test ‘llvm.sqrt.*’ intrinsic
;;;
;;; Syntax:
;;;   This is an overloaded intrinsic. You can use llvm.sqrt on any
;;;   floating-point or vector of floating-point type. Not all targets
;;;   support all types however.
;;;
;;; declare float     @llvm.sqrt.f32(float %Val)
;;; declare double    @llvm.sqrt.f64(double %Val)
;;; declare x86_fp80  @llvm.sqrt.f80(x86_fp80 %Val)
;;; declare fp128     @llvm.sqrt.f128(fp128 %Val)
;;; declare ppc_fp128 @llvm.sqrt.ppcf128(ppc_fp128 %Val)
;;;
;;; Overview:
;;;   The ‘llvm.sqrt’ intrinsics return the square root of the specified value.
;;;
;;; Arguments:
;;;   The argument and return value are floating-point numbers of the same type.
;;;
;;; Semantics:
;;;   Return the same value as a corresponding libm ‘sqrt’ function but without
;;;   trapping or setting errno. For types specified by IEEE-754, the result
;;;   matches a conforming libm implementation.
;;;
;;;   When specified with the fast-math-flag ‘afn’, the result may be
;;;   approximated using a less accurate calculation.
;;;
;;; Note:
;;;   We test only float/double/fp128.
