const char * AArch64Subtarget::getBZeroEntry ( ) const

This function returns the name of a function which has an interface like the non-standard bzero function, if such a function exists on the current subtarget and it is considered prefereable over memset with zero passed as the second argument. Otherwise it returns null.
