--- Comment #11 from Andrew Pinski <pinskia at gcc dot gnu.org> --- I have idea on how to fix the FENV_ACCESS issue (for gimple), basically you add an extra virtual use op for float gimples and virtual define for functions and inline-asm. Now I am not going to implement this but I want to record it somewhere.
