[Bug fortran/31114] Consistent floating point arithmetic model option

[pinskia at gcc dot gnu dot org]

------- Comment #6 from pinskia at gcc dot gnu dot org  2007-03-09 22:45 -------
There is no way to get all the same fp arithmetic model on all targets as some
don't even support IEEE float, SPU comes to mind.

Please read: http://gcc.gnu.org/bugs.html#nonbugs

Also read the paper which is linked from that page:
http://www.validlab.com/goldberg/paper.ps

Again for x86/m68k this is a dup of bug 323.  -ffloat-store and -mieee (if it
exists) are the best options for getting to IEEE fp though again some targets
don't support IEEE at all unless you do it all in software which makes it
slower than you want it.
