If people don't want it, could we add an option to enable thumb2 at

It doesn't because you have the spin_unlock() in the "then" part so it

You need "-O -fno-inline" to trigger it on this particular example
(you don't need "-fno-inline" if you put "Lock" in a separate package).

As a recent committer to GCC, I am always surprised to see the content
of ChangeLog entries and commit messages.
I tend to find GCC ChangeLog entries useless. For example, the more
