Public Member Functions
~SelectionDAGGenTargetInfo () override
const char * getTargetNodeName (unsigned Opcode) const override
Returns the name of the given target-specific opcode, suitable for debug printing.
bool isTargetMemoryOpcode (unsigned Opcode) const override
Returns true if a node with the given target-specific opcode has a memory operand.
bool isTargetStrictFPOpcode (unsigned Opcode) const override
Returns true if a node with the given target-specific opcode has strict floating-point semantics.
void verifyTargetNode (const SelectionDAG &DAG, const SDNode *N) const override
Checks that the given target-specific node is valid. Aborts if it is not.
