Difficult to say.

But we need to figure out how it will look like, it's much easier to experiment with runtime calls.

Review and +1's are welcome. Regarding kernel, we need to put together a TODO list -- there is lots of work. Do you able to build kernel with asan and boot it? Just verifying it and pointing any weak places in our docs would be a good start. Thanks! -- You received this message because you are subscribed to the Google Groups "address-sanitizer" group.
