Comment (by rsd@…):

 Ah, so I made a little test program, and figured out that g++ -ffast-math
 or icpc -O<anything but 0> DO set FTZ (and presumably DAZ) and flush to
 zero, but then they lie about it and set has_denorm to denorm_present
 anyway.

 So do I completely not understand this? Is there some interpretation of
 the standard that says it's compliant to zero denormals and still set
 has_denorm to denorm_present?
