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.

References N, and Size.

◆ EmitTargetCodeForMemset()

Emit target-specific code that performs a memset.

This can be used by targets to provide code sequences for cases that don't fit the target's parameters for simple stores and can be more efficient than using a library call. This function can return a null SDValue if the target declines to use custom code and a different lowering strategy should be used. Note that if AlwaysInline is true the function has to return a valid SDValue.

Reimplemented from llvm::SelectionDAGTargetInfo.
