--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
I can observe the same behavior with trunk.
For func2, we compute a < b ? a : b first and then call sqrtf on that, while
for func3 we have return a < b ? ABS_EXPR <a> : ABS_EXPR <b>;. Perhaps that's
the reason why ifcvt doesn't optimize this using UNSPEC_IEEE_MIN.
