--- Comment #2 from vincenzo Innocente <vincenzo.innocente at cern dot ch> --- Thanks for the fast response I think I can "survive" with -O3 -fno-trapping-math in principle it should not change the binary compatibility of the output w/r/t -O2 and at best of my understanding it does not inhibit raising FP exceptions (we already force -fno-math-errno to avoid errno generation in sqrt...)
