◆ EmitTargetCodeForMemset()
|
overridevirtual |
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.
