Well, your asm cannot modify it as you don't have a use or clobber for FP state (but there isn't any...).
Ah, right, I was focusing on "volatile" and forgot there is no "memory" clobber in those asms, cool, that may simplify things a lot.
Also I think the 'volatile' in the asms isn't needed.
Right, I had it because of PR 56027 where we don't use fesetround but the SSE intrinsics. But according to your comment #3 there, volatile is needed even with fesetround. -- Marc Glisse
