Jan 10, 2008 · From memory, xdelta patches only contain copy and insert instructions. They might contain very small amounts of context for changes under the minimum match length, but the patch file is binary and the context is quite small, so it might still be safe. pd Says: January 11th, 2008 at 6:03 am. Ben what is the conclusion to your story?
In this case the chain b->c is in the critical path (a can be in parallel with b, and the sub has minimal latency); the store is not in the critical path. So as you can see there is an additional dereference. Also it will touch the additional cacheline pointed by data+sz.
