| ;;; Test ‘llvm.minnum.*’ intrinsic |
| ;;; |
| ;;; Syntax: |
| ;;; This is an overloaded intrinsic. You can use llvm.minnum on any |
| ;;; floating-point or vector of floating-point type. Not all targets |
| ;;; support all types however. |
| ;;; |
| ;;; declare float @llvm.minnum.f32(float %Val0, float %Val1) |
| ;;; declare double @llvm.minnum.f64(double %Val0, double %Val1) |
| ;;; declare x86_fp80 @llvm.minnum.f80(x86_fp80 %Val0, x86_fp80 %Val1) |
| ;;; declare fp128 @llvm.minnum.f128(fp128 %Val0, fp128 %Val1) |
| ;;; declare ppc_fp128 @llvm.minnum.ppcf128(ppc_fp128 %Val0, ppc_fp128 %Val1) |
| ;;; |
| ;;; Overview: |
| ;;; The ‘llvm.minnum.*’ intrinsics return the minimum of the two arguments. |
| ;;; |
| ;;; Arguments: |
| ;;; The arguments and return value are floating-point numbers of the same |
| ;;; type. |
| ;;; |
| ;;; Semantics: |
| ;;; Follows the IEEE-754 semantics for minNum, except for handling of |
| ;;; signaling NaNs. This match’s the behavior of libm’s fmin. |
| ;;; |
| ;;; If either operand is a NaN, returns the other non-NaN operand. |
| ;;; Returns NaN only if both operands are NaN. The returned NaN is |
| ;;; always quiet. If the operands compare equal, returns a value |
| ;;; that compares equal to both operands. This means that |
| ;;; fmin(+/-0.0, +/-0.0) could return either -0.0 or 0.0. |
| ;;; |
| ;;; Unlike the IEEE-754 2008 behavior, this does not distinguish between |
| ;;; signaling and quiet NaN inputs. If a target’s implementation follows |
| ;;; the standard and returns a quiet NaN if either input is a signaling |
| ;;; NaN, the intrinsic lowering is responsible for quieting the inputs |
| ;;; to correctly return the non-NaN input (e.g. by using the equivalent |
| ;;; of llvm.canonicalize). |
| ;;; |
| ;;; Note: |
| ;;; We test only float/double/fp128. |
