MachineBasicBlock MachineBasicBlock::iterator DebugLoc DL

This class represents a function call, abstracting a target machine's calling convention.

Wrapper class for IR location info (IR ordering and DebugLoc) to be passed into SDNode creation funct...

Represents one node in the SelectionDAG.

Unlike LLVM values, Selection DAG nodes may return multiple values as the result of a computation.

const char * getTargetNodeName(unsigned Opcode) const override

Returns the name of the given target-specific opcode, suitable for debug printing.

Definition SelectionDAGTargetInfo.h:202

bool isTargetStrictFPOpcode(unsigned Opcode) const override

Returns true if a node with the given target-specific opcode has strict floating-point semantics.

~SelectionDAGGenTargetInfo() override

bool isTargetMemoryOpcode(unsigned Opcode) const override

Returns true if a node with the given target-specific opcode has a memory operand.

Definition SelectionDAGTargetInfo.h:208

void verifyTargetNode(const SelectionDAG &DAG, const SDNode *N) const override

Checks that the given target-specific node is valid. Aborts if it is not.

Definition SelectionDAGTargetInfo.h:220

virtual bool isTargetStrictFPOpcode(unsigned Opcode) const

Returns true if a node with the given target-specific opcode has strict floating-point semantics.

Definition SelectionDAGTargetInfo.h:53

virtual bool mayRaiseFPException(unsigned Opcode) const

Returns true if a node with the given target-specific opcode may raise a floating-point exception.

virtual bool isTargetMemoryOpcode(unsigned Opcode) const

Returns true if a node with the given target-specific opcode has a memory operand.

Definition SelectionDAGTargetInfo.h:49

virtual void verifyTargetNode(const SelectionDAG &DAG, const SDNode *N) const

Checks that the given target-specific node is valid. Aborts if it is not.
