You can use llvm.copysign on any 7;;; floating-point or vector of floating-point type. Not all targets 8;;; support all types however. 9;;; 10;;; declare float @llvm.copysign.f32(float %Mag, float %Sgn) 11;;; declare double @llvm.copysign.f64(double %Mag, double %Sgn) 12;;; declare x86_fp80 @llvm.copysign.f80(x86_fp80 %Mag, x86_fp80 %Sgn) 13;;; declare fp128 @llvm.copysign.f128(fp128 %Mag, fp128 %Sgn) 14;;; declare ppc_fp128 @llvm.copysign.ppcf128(ppc_fp128 %Mag, ppc_fp128 %Sgn) 15;;; 16;;; Overview: 17;;; The ‘llvm.copysign.*’ intrinsics return a value with the magnitude of 18;;; the first operand and the sign of the second operand. 19;;; 20;;; Arguments: 21;;; The arguments and return value are floating-point numbers of the same 22;;; type. 23;;; 24;;; Semantics: 25;;; This function returns the same values as the libm copysign functions 26;;; would, and handles error conditions in the same way. 27;;; 28;;; Note: 29;;; We test only float/double/fp128. 30 31; Function Attrs: nounwind readnone 32define float @copysign_float_var(float %0, float %1) { 33;
