;;; Test ‘llvm.copysign.*’ Intrinsic
;;;
;;; Syntax:
;;;   This is an overloaded intrinsic. You can use llvm.copysign on any
;;;   floating-point or vector of floating-point type. Not all targets
;;;   support all types however.
;;;
;;; declare float     @llvm.copysign.f32(float  %Mag, float  %Sgn)
;;; declare double    @llvm.copysign.f64(double %Mag, double %Sgn)
;;; declare x86_fp80  @llvm.copysign.f80(x86_fp80  %Mag, x86_fp80  %Sgn)
;;; declare fp128     @llvm.copysign.f128(fp128 %Mag, fp128 %Sgn)
;;; declare ppc_fp128 @llvm.copysign.ppcf128(ppc_fp128  %Mag, ppc_fp128  %Sgn)
;;;
;;; Overview:
;;;   The ‘llvm.copysign.*’ intrinsics return a value with the magnitude of
;;;   the first operand and the sign of the second operand.
;;;
;;; Arguments:
;;;   The arguments and return value are floating-point numbers of the same
;;;   type.
;;;
;;; Semantics:
;;;   This function returns the same values as the libm copysign functions
;;;   would, and handles error conditions in the same way.
;;;
;;; Note:
;;;   We test only float/double/fp128.
