http://www.fortran.bcs.org/2007/jubilee/f50.pdf, the following:

IEEE module implementation
• Only if IEEE_GET_FLAG is directly called in a routine: save then clear the
flags on entry, merge the flags on exit.
• Only in a routine that uses a mode setting procedure: save mode on entry,
restore mode on exit.
• Parallelism and other optimisations are little impeded by the use of IEEE
facilities (all IEEE semantics being local).
