Note that you could probably just reload the tmp1_var value rather than needing to store the fsr value again to clear exceptions from it, unless there's an architecture-specific reason the tmp1_var value might no longer be the right value to load to clear exceptions. (This is what x86 does for SSE state, loading the same value for exceptions-cleared SSE state every iteration of the loop.) -- Joseph S. Myers jos...@codesourcery.com
