[PATCH 2/3] Add default implementation of fenv.h and all methods
Joel Sherrill
joel@rtems.org
Wed Jul 31 23:14:00 GMT 2019
The default implementation of the fenv.h methods return
-EOPNOTSUPP.
The intention of the new fenv.h is that it be portable
and that architectures provide their own implementation
of sys/fenv.h.
