+;;; 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.
