Well, I have a question about why is it not enough to use use/def in MI level to prevent the reordering of instructions about set/get fp status register. For example, If the instruction which setting rounding mode, and then the instruction which read the rounding mode, the sequence would not be reordered because of the dependency of rounding mode bits (fp status register).
