[Qemu-devel] [PULL 12/51] target-arm: A64: Implement DC ZVA

2014-04-17 Thread Peter Maydell
Implement the DC ZVA instruction, which clears a block of memory. The fast path obtains a pointer to the underlying RAM via the TCG TLB data structure so we can do a direct memset(), with fallback to a simple byte-store loop in the slow path. Signed-off-by: Peter Maydell Reviewed-by: Richard Hend
