Duncan, Your effort to improve the control of floating point optimizations in LLVM is noble and commendable. I'd like to make two points that appear not to have been raised previously in the discussion of your proposal to date: 1) Most compiler and back-end control of floating point behavior appears to be motivated by controlling the loss or gain of a few low bits of precision
