Ensure AbaPtr is not used in runtime code

2017-10-20T02:17:12+00:00

The AbaPtr makes assumptions that we have pointer values that are only 32-bits long. In our runtime (HBRT) environment that assumption is not true so we need to make sure none of the code that runs there is trying to use the AbaPtr code.

Implement a lockfree ABA-safe smart pointer.

2015-04-24T16:35:17+00:00

* Use algorithm from lockfree stack as basis. * Convert lockfree stack to use new ABA-safe pointer. * Convert trace service to use ABA-safe pointers on client buffer pages to resolve futex hang due to page reuse.
