Thanks. We are close to branching an RTEMS release.
Sounds like this will be a good thing to switch to
immediately after that.

I highly recommend switching to the EABI.
If you want to support recent (Thumb-2) CPUs I'd expect that you pretty much
have to use an EABI based target.
What is the difference and how will it impact code? I am
worried about our assembly code.
The main visible change is that that you must preserve 8-byte stack alignment
at public entry points.
Is there a standard conditional to know the difference if
it matters?
