I do not intend to back-port the jump-thread patches to the fsf gcc 4.9 branch: the patches I sent are only for the linaro 4.9 branch.
Yes, please test the patches with your validation suite, and then commit to the linaro branch.
Thanks,
Sebastian

Our 4.9 branch is now in maintenance mode, which means that we're only
backporting bugfixes on it, and synchronizing it with upstream 4.9
branch. So, if you'll only backport them to AOSP and not FSF gcc 4.9,
yes it can be beneficial for our branch, but we first have to pass
them into our validation process.
Cheers,
Yvan
