--- Comment #1 from Marc Glisse <glisse at gcc dot gnu.org> --- Is there a convenient way for gcc to know the value of FE_DIVBYZERO, etc on the target? Do we need to hardcode it? Can we rely on different libc on the same processor to use the same value? What happens if the user calls feraiseexcept and compiles with -fno-trapping-math?
