--- Comment #1 from mikulas at artax dot karlin.mff.cuni.cz ---
It turns out (reading bug 37179) that there are other processors that don't
support ffreep - i486-class vortex86sx and i586-class AMD Geode.

Consequently, the instruction should only be generated when using i686 or
better
instruction set. When compiling the above code with "-m32 -O2 -march=i486
-mtune=athlon" or "-m32 -O2 -march=geode -mtune=athlon", the ffreep instruction
is also incorrectly generated.
