Methods

¶ConstantFPSDNode(bool isTarget,
                 const llvm::ConstantFP* val,
                 llvm::EVT VT)

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1623

Parameters

bool isTarget

const llvm::ConstantFP* val

llvm::EVT VT

¶static bool classof(const llvm::SDNode* N)

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1659

Parameters

const llvm::SDNode* N

¶const llvm::ConstantFP* getConstantFPValue() const

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1630

¶const llvm::APFloat& getValueAPF() const

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1629

¶bool isExactlyValue(double V) const

Description

We leave the version with the double argument here because it's just so convenient to write "2.0" and the like. Without this function we'd have to duplicate its logic everywhere it's called.

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1652

Parameters

double V

¶bool isExactlyValue(const llvm::APFloat& V) const

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1655

Parameters

const llvm::APFloat& V

¶bool isInfinity() const

Description

Return true if the value is an infinity

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1639

¶bool isNaN() const

Description

Return true if the value is a NaN.

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1636

¶bool isNegative() const

Description

Return true if the value is negative.

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1642

¶static bool isValueValidForType(
    llvm::EVT VT,
    const llvm::APFloat& Val)

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1657

Parameters

llvm::EVT VT

const llvm::APFloat& Val

¶bool isZero() const

Description

Return true if the value is positive or negative zero.
