It will take over the world tomorrow afternoon at 3 o'clock.

Come on, people, you know it will take years.

There is not much to write about for LRA from user's perspective as generated code is 1-2% SLOWER, so we'll have to wait for 4.9 to see any real benefit...

did you rebuild your libraries with it? wouldn't you need your low-level hw access (like stdio.h) be astemic throughout? Not sure but if not, you may have redundancy in your functions.

At least until it produces some real benefit that will be visible in the compiled code and worth the upgrade.
