Re: [PATCH][GCC][PATCHv3] Improve fpclassify w.r.t IEEE like numbers in GIMPLE.


Also, I don't think the call to perform_ibm_extended_fixups in 
is_subnormal is correct.  Subnormal for IBM long double is *not* the same 
as subnormal double high part.  Likewise it's incorrect in is_normal as 
well.

Generally, I don't see tests added that these new functions are correct 
for float, double and long double, which would detect such issues if run 
for a target with IBM long double.
