[Bug tree-optimization/39764] ICE in set_lattice_value, at tree-ssa-ccp.c:468 with -ffinite-math-only

[rguenth at gcc dot gnu dot org]

------- Comment #3 from rguenth at gcc dot gnu dot org  2009-04-15 12:31 -------
We drop back from CONSTANT (NaN) to UNDEFINED because of
canonicalize_float_value.

I have a fix.
