;;; Test ‘llvm.fma.*’ intrinsic
;;;
;;; Syntax:
;;; This is an overloaded intrinsic. You can use llvm.fma on any
;;; floating-point or vector of floating-point type. Not all targets
;;; support all types however.
;;;
;;; declare float @llvm.fma.f32(float %a, float %b, float %c)
;;; declare double @llvm.fma.f64(double %a, double %b, double %c)
;;; declare x86_fp80 @llvm.fma.f80(x86_fp80 %a, x86_fp80 %b, x86_fp80 %c)
;;; declare fp128 @llvm.fma.f128(fp128 %a, fp128 %b, fp128 %c)
;;; declare ppc_fp128 @llvm.fma.ppcf128(ppc_fp128 %a, ppc_fp128 %b,
;;; ppc_fp128 %c)
;;;
;;; Overview:
;;; The ‘llvm.fma.*’ intrinsics perform the fused multiply-add operation.
;;;
;;; Arguments:
;;; The arguments and return value are floating-point numbers of the same
;;; type.
;;;
;;; Semantics:
;;; Return the same value as a corresponding libm ‘fma’ function but without
;;; trapping or setting errno.
;;;
;;; 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.
