Options not documented by gfortran are (usually) common options and thus
documented by gcc. Sometimes we just forget to document them, but not in this
case. See:
http://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html#index-ffloat_002dstore-589
http://gcc.gnu.org/onlinedocs/gcc/Disappointments.html#index-ffloat_002dstore-2709
