;;; 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.
