--- Comment #3 from Florian Schanda <florian.schanda at bmw dot de> --- Maybe some additional constraints under which we operate can help: - we never change our rounding mode away from RNE - we never disable support for subnormals in any way - we only ever use float32 and float64, we do not use the intel extended precision format Under those constraints, will -fsignaling-nans work?
