--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note that phiopt could still do min/max detection of a derived value, thus
for the PHI args look through unary ops it can associate a min/max with
and re-write as op (min/max (a, b)). Not sure if that's worth it complicating
the code.
Other than that removing the
else if (TREE_CODE (arg0) == COND_EXPR)
{
from fold_unary that does the operation sinking would "fix" this as well.
