As I spoke to you about this at the Summit, the users of the AVR port,
and I would also postulate the general embedded community, would
*really* like to have this functionality, especially your Stage 1. There
are many AVR, or embedded, applications where they are generally
optimized for size, but have a time-critical function that needs to be
optimized for speed. I would vote for including both the attribute
syntax and the pragma syntax. I have many users who would be more
comfortable with the pragma syntax, despite any shortcomings.
