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