OE however has not activated the functionality. I'm starting to see some data base programs (and RPM) that can make use of the functionality to create better thread-safe code. This includes a patch to GCC. I've verified it is working based on the recent rpm 5.4.16 work. It also should not expand the size of the target unless the user adds the libitm support to their system. I'd recommend we consider this patch to enable the additional support.
