/* GCC uses unordered comparison instructions like cebr (Short BFP COMPARE)
   when it should use ordered comparison instructions like kebr
   (Short BFP COMPARE AND SIGNAL) in order to raise invalid exceptions if
   any operand is quiet (or signaling) NAN. See gcc bugzilla:
   <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77918>.
   There exists an equivalent gcc bugzilla for Intel:
   <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52451>.
   This s390 gcc bug is fixed with gcc 10, thus we don't need the workaround
   to call feraiseexcept (FE_INVALID) in math/s_iseqsig_template.c.  */
