Sure, the tests are of utmost importance here. By the way, in what suite should they be?
As for the changes in the compiler itself - what do you think about introduction of a fake variable, reflecting rounding mode (similar variables could be introduced for exception flags and other properties). How difficult would it be to do that (we'll need to add implicit dependencies from those variables to all FP-operations and kill their values after each call)?
