Yup, that's what I had gathered.  I am very much looking forward to the new
back-end going up.  I'd love to help out with it.

Indeed, I was tracking your conversation about function preambles.  It seems
like while supporting both the IAR and GCC styles would be very useful
(perhaps with IAR behind a flag) it would also be considerable work.  Have

You mentioned about helping on the Clang side, that would be awesome because
